  5. Glutathione transferases in the bioactivation of azathioprine.

    The prodrug azathioprine is primarily used for maintaining remission in inflammatory bowel disease, but approximately 30% of the patients suffer adverse side effects. The prodrug is activated by glutathione conjugation and release of 6-mercaptopurine, a reaction most efficiently catalyzed by glutathione transferase (GST) A2-2. Among five genotypes of GST A2-2, the variant A2*E has threefold-fourfold higher catalytic efficiency with azathioprine, suggesting that the expression of A2*E could boost 6-mercaptopurine release and adverse side effects in treated patients. Structure-activity studies of the GST A2-2 variants and homologous alpha class GSTs were made to delineate the determinants of high catalytic efficiency compared to other alpha class GSTs. Engineered chimeras identified GST peptide segments of importance, and replacing the corresponding regions in low-activity GSTs by these short segments produced chimeras with higher azathioprine activity. By contrast, H-site mutagenesis led to decreased azathioprine activity when active-site positions 208 and 213 in these favored segments were mutagenized. Alternative substitutions indicated that hydrophobic residues were favored. A pertinent question is whether variant A2*E represents the highest azathioprine activity achievable within the GST structural framework. This issue was addressed by mutagenesis of H-site residues assumed to interact with the substrate based on molecular modeling. The mutants with notably enhanced activities had small or polar residues in the mutated positions. The most active mutant L107G/L108D/F222H displayed a 70-fold enhanced catalytic efficiency with azathioprine. The determination of its structure by X-ray crystallography showed an expanded H-site, suggesting improved accommodation of the transition state for catalysis.

  7. Are we giving azathioprine too much time?

    Azathioprine is Currently the key drug in the maintenance treatment of inflammatory bowel diseases. However, there are still some practical issues to be resolved: one is how long we must maintain the drug. Given that inflammatory bowel diseases are to date chronic, non-curable conditions, treatment should be indefinite and only the loss of efficacy or the appearance of serious side effects may cause withdrawal. As regards to efficacy and their maintenance over time, evidence supports the continuous usefulness of the drug in the long term: in fact its withdrawal very substantially increases the risk of relapse. About side effects, azathioprine is a relatively well tolerated drug and even indefinite use seems safe. The main theoretical risks of prolonged use would be the myelotoxicity, hepatotoxicity, and the development of cancer. In fact, serious bone marrow suppression or serious liver damage are uncommon, and can be minimized with proper use of the drug. Recent metanalysis suggests that the risk of lymphoma is real, but the individual risk is rather low, and decision analysis suggests a favorable benefit/risk ratio in the long term. Therefore, in patients with inflammatory bowel diseases in whom azathioprine is effective and well tolerated, the drug should not be stopped. This recommendation concerns the use of azathioprine as a single maintenance drug, and is not necessarily applicable to patients receiving concomitant biological therapy.

    Azathioprine is an immunosuppressive drug that has shown effectiveness in inflammatory bowel disease treatment. Its metabolite, 6-mercaptopurine, is metabolized through thiopurine methyltransferase. Patients with low enzyme activity may have more frequent and severe side effects. The most common is leukopenia, and rarely pancytopenia. The thiopurine methyltransferase activity monitoring shows an individualized profile of enzymatic activity but it should not replace monitoring by performing serial blood counts. In patients with fever and severe neutropenia, early empirical antibiotic treatment should be initiated to prevent severe and disseminated infection. Two patients with this condition are reported.

    2015-01-01

    Full Text Available Background: Azathioprine in daily doses has been shown to be effective and safe in the treatment of Parthenium dermatitis. Weekly pulses of azathioprine (WAP are also effective, but there are no reports comparing the effectiveness and safety of these two regimens in this condition. Aims: To study the efficacy and safety of WAP and daily azathioprine in Parthenium dermatitis. Methods: Sixty patients with Parthenium dermatitis were randomly assigned to treatment with azathioprine 300 mg weekly pulse or azathioprine 100 mg daily for 6 months. Patients were evaluated every month to assess the response to treatment and side effects. Results: The study included 32 patients in the weekly azathioprine group and 28 in the daily azathioprine group, of whom 25 and 22 patients respectively completed the study. Twenty-three (92% patients on WAP and 21 (96% on daily azathioprine had a good or excellent response. The mean pretreatment clinical severity score decreased from 26.4 ± 14.5 to 4.7 ± 5.1 in the WAP group, and from 36.1 ± 18.1 to 5.7 ± 6.0 in the daily azathioprine group, which was statistically significant and comparable (P = 0.366. Patients on WAP had a higher incidence of adverse effects (P = 0.02. Limitations: The study had a small sample size and the amount of clobetasol propionate used in each patient was not determined, though it may not have affected the study outcome due to its comparable use in both groups. Conclusions: Azathioprine 300 mg weekly pulse and 100 mg daily dose are equally effective and safe in the treatment of Parthenium dermatitis.

  11. Early pregnancy azathioprine use and pregnancy outcomes.

    2012-02-01

    BACKGROUND: Azathioprine (AZA) is used during pregnancy by women with inflammatory bowel disease (IBD), other autoimmune disorders, malignancy, and organ transplantation. Previous studies have demonstrated potential risks. METHODS: The Swedish Medical Birth Register was used to identify 476 women who reported the use of AZA in early pregnancy. The effect of AZA exposure on pregnancy outcomes was studied after adjustment for maternal characteristics that could act as confounders. RESULTS: The most common indication for AZA use was IBD. The rate of congenital malformations was 6.2% in the AZA group and 4.7% among all infants born (adjusted OR: 1.41, 95% CI: 0.98-2.04). An association between early pregnancy AZA exposure and ventricular\\/atrial septal defects was found (adjusted OR: 3.18, 95% CI: 1.45-6.04). Exposed infants were also more likely to be preterm, to weigh <2500 gm, and to be small for gestational age compared to all infants born. This effect remained for preterm birth and low birth weight when infants of women with IBD but without AZA exposure were used as a comparison group. A trend toward an increased risk of congenital malformations was found among infants of women with IBD using AZA compared to women with IBD not using AZA (adjusted OR: 1.42, 95% CI: 0.93-2.18). CONCLUSIONS: Infants exposed to AZA in early pregnancy may be at a moderately increased risk of congenital malformations, specifically ventricular\\/atrial septal defects. There is also an increased risk of growth restriction and preterm delivery. These associations may be confounded by the severity of maternal illness.

  12. Biochemical and morphological study on hepatotoxicity of azathioprine in rat.

    Directory of Open Access Journals (Sweden)

    Watanabe,Akiharu

    1979-02-01

    Full Text Available Sprague-Dawley rats given azathioprine in the diet for 3 to 4 weeks developed severe liver damage. Elevations of serum alkaline phosphatase and gamma-glutamyl transpeptidase activities were associated with increased hepatic glucose 6-phosphate dehydrogenase levels and decreased liver glucose 6-phosphatase activities, i.e., conditions which were commonly observed in various hepatotoxin-induced liver injuries. Light and electron microscopic observations revealed centrolobular necrosis with large scars and the proliferation of the mitochondria and rough endoplasmic reticulum. This model could be used to study the mechanisms of azathioprine-induced liver damage and its prevention.

    Azathioprine is a purine antimetabolite drug commonly used to treat inflammatory bowel disease (IBD). In vivo it is active after reaction with reduced glutathione (GSH) and conversion to mercaptopurine. Although this reaction may occur spontaneously, the presence of isoforms M and A of the enzyme glutathione-S-transferase (GST) may increase its speed. Indeed, in pediatric patients with IBD, deletion of GST-M1, which determines reduced enzymatic activity, was recently associated with reduced sensitivity to azathioprine and reduced production of azathioprine active metabolites. In addition to increase the activation of azathioprine to mercaptopurine, GSTs may contribute to azathioprine effects even by modulating GSH consumption, oxidative stress and apoptosis. Therefore, genetic polymorphisms in genes for GSTs may be useful to predict response to azathioprine even if more in vitro and clinical validation studies are needed.

    Myasthenia gravis (MG) is an autoimmune neuromuscular disorder characterised by fatigable voluntary skeletal muscle weakness. The underlying pathogenesis is complex involving adaptive autoimmune responses. Azathioprine remains a first line broad acting immunosuppressant for MG. Due to varied clinical responses to azathioprine we aimed to investigate the relationship between azathioprine metabolites and symptom control. Mild correlations between Quantitative Myasthenia Gravis Score (QMG) vs. 6-thioguanine nucleotides (R=-0.317 p=0.186) and QMG vs. lymphocyte count (R=0.402 p=0.08) were found. Azathioprine metabolite measurement should be considered in MG patients with; pancytopenia, deranged liver function or recurrent infections.

    Increased rates of NMSC (nonmelanoma skin cancer) have recently been reported in people with MG (myasthenia gravis) receiving azathioprine treatment. Guidelines on azathioprine for patients with dermatological and gastrointestinal disorders stress the importance of NMSC risk awareness and prevention. The aim of this study is to assess whether MG patients are being informed of this risk.

  19. Protective effect of pumpkin seed oil against genotoxicity induced by azathioprine

    2012-10-01

    Full Text Available Pumpkin is a leafy green vegetable; it belongs to the Cucurbitaceae family. Pumpkin seed oil supplementation can prevent changes in plasma lipids and blood pressure. The present study was conducted to evaluate the protective effect of pumpkin seed oil against cytotoxicity and genotoxicity of azathioprine. Oral administration of pumpkin seed oil either before or after treatment of azathioprine was effective in the reduction of the frequencies of Mn-PCEs, decreased the DNA fragmentation, total sperm abnormalities and significantly increased sperm count, percentage of PCEs, and enhanced the ratio of PCEs to NCEs. However, random amplified polymorphism of DNA (RAPD showed distinct differences in animal groups intoxicated with azathioprine before and after pumpkin seed oil treatment, which reflected a DNA protective effect of pumpkin seed oil. Depletion of glutathione content in the testis was also observed in azathioprine treated mice, which was improved by an oral administration of pumpkin seed oil either before or after treatment with azathioprine.

    Azathioprine (AZA) is used clinically sometimes at high doses for short-term therapy to treat acute rejection of kidney allograft or to desensitize hypersensitive patients to it. The delayed consequences of this approach had not been well investigated. Therefore, in this study we have investigated the delayed consequences of high-dose short-term AZA administration in rabbits. Our results showed that oral administration of AZA (10 mg/kg/day) to rabbits for two weeks induced reversible thrombocytosis and delayed fatal macrocytic anemia. Moreover, neither the hemoglobin level nor the white blood cell count was affected by AZA. The solvent of AZA had no effect on blood cell counts and hemoglobin levels. We can conclude that although high-dose AZA therapy may not induce immediate and significant changes in blood picture, delayed fatal macrocytosis may occur.

    Early rejection can still complicate renal transplantation even with cyclosporin. We added low-dose allopurinol (25 mg on alternative days) to "triple" immunosuppression with cyclosporin, prednisolone, and azathioprine for twelve recipients of cadaver renal grafts. The controls were fifteen patients on triple therapy alone. Only one rejection episode occurred among the allopurinol-treated patients, whereas eleven controls had rejections (seven with more than one episode). Allopurinol may be toxic when combined with azathioprine, yet the bone marrow tolerated the new regimen well. As expected, reduction of the azathioprine dose was necessary in the treated group.

    The early hypersensitivity reaction and late bone marrow depression are well-known side-effects of azathioprine,whereas interstitial pneumonia is a rare complication.A 40-year old male patient had been treated with azathioprine in consequence of extensive ulcerative colitis for 10 years. He then complained of 7 d of fever,cough and catarrhal signs, without symptoms of active colitis. Opportunistic infections were ruled out. The chest X-ray, CT and lung biopsy demonstrated the presence of interstitial inflammation. Azathioprine therapy was discontinued as a potential source of the pulmonary infiltrate. In response to steroid therapy, and intensive care, the pulmonary infiltrate gradually decreased within 4 wk. Three months later, his ulcerative colitis relapsed,and ileo-anal pouch surgery was performed. In cases of atypical pneumonia, without a proven infection,azathioprine-associated interstitial pneumonitis may be present, which heals after withdrawal of the drug.

    1992-05-01

    The immunosuppressive efficacy of azathioprine is related to its rapid metabolism in vivo to 6-mercaptopurine (6MP), with subsequent conversion to thioguanine nucleotides by an anabolic route involving hypoxanthine-guanine phosphoribosyltransferase. Two alternative catabolic routes exist: oxidation to 6-thiouric acid via xanthine oxidase and methylation to 6-methylmercaptopurine via the enzyme thiopurine methyltransferase (TPMT). Catabolism via either route would restrict formation of the active metabolites. We analyzed TPMT activity in erythrocyte lysates of 25 controls, 25 uremic patients on dialysis, and 68 transplanted patients. Median activity was lower in controls (31.0 pmol/hr/mg Hb, range 16.2-43.0) and transplanted patients receiving only cyclosporine and prednisolone (31.7 pmol/hr/mg Hb, range 12.7-43.5) than in the azathioprine treated group, (36.1 pmol/hr/mg Hb, range 16.1-71.3), or the uremic group on dialysis, (35.5 pmol/hr/mg Hb, range 18.6-62.6) suggesting that both azathioprine and uremia induce the enzyme, but CsA does not. Only 3 patients demonstrated total intolerance to azathioprine, 2 of whom had very low TPMT activity (zero and 12.7 pmol/hr/mg Hb). The intolerance of the third patient, despite high TPMT activity, was attributed to concomitant cotrimoxazole therapy. Patients with intermediate activity (15-26 pmol/hr/mg Hb) could tolerate azathioprine well. Of 29 cadaver recipients given only azathioprine plus prednisolone, 24 with a better clinical outcome had a significantly lower activity (33.1 pmol/hr/mg Hb, range 16.1-46.1) than 5 with reduced allograft function (42.5 pmol/hr/mg Hb, range 33.8-51.5). TPMT activity in these 24 patients was also significantly lower than the general group of azathioprine-treated recipients. This inverse association between TPMT activity and allograft function was again found among 30 patients receiving triple therapy (azathioprine, CsA, prednisolone).

  4. Azathioprine associated acute respiratory distress syndrome: case report and literature review

    Directory of Open Access Journals (Sweden)

    Scherbak D

    2014-08-01

    Full Text Available A 58-year-old Caucasian man treated with azathioprine to prevent rejection of an orthotopic liver transplant, presented to the Carl Hayden VA Medical Center with rapid respiratory decline and appeared septic. He required urgent intubation, mechanical ventilator support and empiric antibiotics. His clinical picture and imaging studies were consistent with acute respiratory distress syndrome; however, extensive infectious work up failed to reveal an offending organism. Review of his current medications implicated azathioprine and upon discontinuation of this agent, the patient made a rapid recovery. He was subsequently extubated, transferred out of the ICU and soon discharged home in good health. Prescribed for organ transplant rejection and a wide array of autoimmune diseases, azathioprine has been rarely correlated with pneumonitis and rapid respiratory failure. No reported cases were found in which azathioprine was used to treat liver transplant rejection and associated with development of the adult respiratory distress syndrome (ARDS. However, there have been ARDS cases in which azathioprine was used for other purposes. We review all the available cases of azathioprine associated ARDS. The patients in these reports had similar clinical symptoms on presentation as our patient: hypoxia, febrile episodes and rapid development of ARDS with no infectious etiology. Most notable is the rapid resolution of ARDS after discontinuation of azathioprine. Although azathioprine toxicity related respiratory failure is rare, this correlation should still be considered in the differential for immunosuppressed patients presenting with rapid pulmonary decline. Further studies are needed and warranted to better correlate this connection, but it is imperative to recognize that the relationship exists.

    Possible interaction between immunosuppressive drug, azathioprine, and calf thymus DNA was explored by cyclic voltammetry, spectrophotometry, competitive spectrofluorimetry, circular dichroism spectroscopy (CD), and viscosity measurements. Cyclic voltammetry showed negative shift in the reduction peak of azathioprine in the presence of DNA, and large decrease in peak current, referring to the predominance of electrostatic forces. The binding constant was calculated to be 1.22×10(3)M(-1). Absorption hyperchromism without shift in wavelength was observed when DNA was added to azathioprine solution. Competitive fluorescence experiments were conducted by using Hoechst 33258 and methylene blue as probes for minor groove and intercalation binding modes, respectively. The studies showed that azathioprine could release Hoechst 33258, while negligible effect was detected in the case of methylene blue. Stern-Volmer quenching constant (KSV) and complex formation constant (Kf) were obtained from the fluorescence measurements to be 7.6×10(3)M(-1) and 7.76×10(4)M(-1), respectively, at 298K. Enthalpy and entropy changes during the interaction between azathioprine and DNA were calculated from Van't Hoff plot (ΔH=-20.2kJmol(-1); ΔS=26.11Jmol(-1)K(-1) at 298K) which showed an exothermic spontaneous reaction, and involvement of electrostatic forces in the complex formation with DNA. Moreover, circular dichroism studies revealed that azathioprine induced detectable changes in the negative band of DNA spectrum. Viscosity of DNA solution decreased in the presence of azathioprine, showed a non-intercalative mode of interaction. Finally, molecular docking calculations showed that in the lowest energy level of drug-DNA complex, azathioprine approaches the minor grooves of DNA.

    Thiopurines have been shown to effectively maintain remission of both Crohn's disease (CD) and ulcerative colitis (UC), and to behave as disease modifiers if used for >12 months in UC. Gastric intolerance manifesting as nausea constitutes a demanding drawback of thiopurines, at times forcing treatment discontinuance. A few studies have now indicated that some patients might tolerate mercaptopurine (6-MP) for azathioprine. In this paper, we review the literature, and reappraise our own data against the published figures. The data which form the basis for this study span over all visit reports that were released between January 2008 and December 2011 in a primary care Hospital, in Turin, Italy. For the aim of this study we searched our own database and the MedLine using the key-words "azathioprine", "mercaptopurine", "thiopurine", "inflammatory bowel disease", "Crohn's disease", "ulcerative colitis". We retrieved 85 azathioprine prescriptions for 42 UC, 37 CD, and 6 miscellaneous patients. There were 10 episodes of gastric intolerance to azathioprine, which were switched to 6-MP: 6 out of 10 (60%) responded and tolerated the switch drug in a median follow-up of 66 months. Female gender prevailed (p=0.038) in the azathioprine intolerant subset. A trial with 6-MP is worth being offered to azathioprine intolerant inflammatory bowel disease subjects at any center matching the standard figures of specific performance.

    2011-04-01

    Full Text Available Background: Rosemary is widely found along the coasts of the Mediterranean Sea. Its leaves or extract were found to have a high antioxidant and anti-inflammatory activity. It is also used as an antispasmodic, analgesic, anti-rheumatic and expectorant. These actions are mainly due to its content of essential oils. Azathioprine (AZA is an immunosuppressive drug. It is widely used in many diseases. A major drawback is the occurrence of side-effects, especially acute pancreatitis. Aim of the work: This work was done to study the effect of dietary supplement of rosemary leaves as a strategy for amelioration of the side-effects of azathioprine. Material and Methods: Thirty-two adult male albino rats were used in this study. They were equally divided into four groups. Group I: control group, group II: rosemary group, the animals were given a daily oral dose of rosemary leaves extract. Group III: azathioprine group, the animals were given a single dose of AZA intraperitoneally. Group IV: rosemary azathioprine group: the rats were given daily doses of rosemary leaves extract then azathioprine in the last day of the experiment as in the previous regimen. The experiment continued for ten days. Blood samples were taken from all groups and examined for tumour necrosis factor alpha, serum amylase enzyme, C-reactive protein and renal function tests (serum urea and creatinine. Results: Rosemary significantly decreased the levels of tumour necrosis factor alpha, serum amylase enzyme and serum urea and C-reactive protein in rosemary AZA group compared to AZA group . Conclusion: The aqueous rosemary leaves extract has the ability to ameliorate the biochemical pathways of the side-effects of azathioprine, so it is advisable to give it concomitantly to patients treated by azathioprine.

Cases were patients with MG with a first time...... diagnosis of cancer (except non-melanoma skin cancer) registered during 2000-2009, and controls were patients with MG with no history of cancer. Prior use of azathioprine in cases and controls was assessed through prescription records (1995-2009). We used unconditional logistic regression to calculate odds...... ratios (ORs) with 95% confidence intervals (CIs) for cancer associated with a high cumulative dose [≥ 1000 defined daily doses (DDD)] or long-term use (≥ 5 years) of azathioprine, compared with never use of the drug and adjusted for potential confounders. RESULTS: We identified 89 cases and 873 controls...

    Meneses, Cristina; Rada, Gabriel

    2015-07-08

    The treatment of polymyositis is based on corticosteroid therapy, with addition of azathioprine for non responsive cases or as an attempt to diminish corticosteroids requirements. However, there is no clear evidence of its benefit in controlling symptoms. Searching in Epistemonikos database, which is maintained by screening 30 databases, we identified only one systematic review including one pertinent randomized trial. We generated a summary of findings following the GRADE approach. We concluded there is uncertainty if azathioprine improves or not muscular strength in polymyositis because the certainty of the evidence is very low.

    Patients with inflammatory bowel disease have normal life expectancy and, due to modern immunosuppressive therapies, also a normal quality of life. Since mostly young people are affected, their social behaviour suits this environment. Alcohol binging is an increasingly disturbing factor among young people. We describe a patient with Crohn's disease, treated with azathioprine,who developed peliosis hepatis after three epsiodes of alcohol binging. Liver toxicity was not observed previously during the course of the treatment.Azathioprine-induced peliosis hepatis is thought to be idiosyncratic in humans. From animal studies, however,it is clear that hepatic depletion of glutathione leads to azathioprine toxicity to the sinusoidal endothelial cells. Damage of these cells causes peliosis hepatis.Since alcohol binging leads to hepatic glutathione depletion, we conclude that in our patient the episodes of binging have reduced liver gluathione content and therefore this has increased azathioprine toxicity causing peliosis hepatis. The problem of alcohol binging has not yet been addressed in IBD patients undertaking immunosuppressive therapy. This should be reviewed in future considerations regarding patients advice.

    Full Text Available Introduction: regenerative nodular hyperplasia (RNH is a rare liver disease with an etiology that is not well understood. Among the etiological factors are purine-analogue drugs such as azathioprine. Case report: we present a case of a 47-year-old patient diagnosed with Crohn's disease in treatment with azathioprine due to corticosteroid dependency who developed RNH with clinical and laboratory signs of portal hypertension one year after starting treatment. After discontinuation of azathioprine, the patient started treatment and, given the poor disease progression, started treatment with adalimumab. This was continued with an excellent response and without deleterious effects on the liver. Discussion: the relevance of this case is twofold: First, this is a rare and early side effect of azathioprine treatment and this is an irreversible disease with potentially serious complications. Second, because treatment was carried out with biological drugs (adalimumab despite the patient having advance liver disease with portal hypertension without any evidence of its worsening, nor signs of deleterious effects or complications, given that there is scarce or no experience with adalimumab treatment in this type of situation.

  16. Structural determinants of glutathione transferases with azathioprine activity identified by DNA shuffling of alpha class members.

    2008-02-01

    A library of alpha class glutathione transferases (GSTs), composed of chimeric enzymes derived from human (A1-1, A2-2 and A3-3), bovine (A1-1) and rat (A2-2 and A3-3) cDNA sequences was constructed by the method of DNA shuffling. The GST variants were screened in bacterial lysates for activity with the immunosuppressive agent azathioprine, a prodrug that is transformed into its active form, 6-mercaptopurine, by reaction with the tripeptide glutathione catalyzed by GSTs. Important structural determinants for activity with azathioprine were recognized by means of primary structure analysis and activities of purified enzymes chosen from the screening. The amino acid sequences could be divided into 23 exchangeable segments on the basis of the primary structures of 45 chosen clones. Segments 2, 20, 21, and 22 were identified as primary determinants of the azathioprine activity representing two of the regions forming the substrate-binding H-site. Segments 21 and 22 are situated in the C-terminal helix characterizing alpha class GSTs, which is instrumental in their catalytic function. The study demonstrates the power of DNA shuffling in identifying segments of primary structure that are important for catalytic activity with a targeted substrate. GSTs in combination with azathioprine have potential as selectable markers for use in gene therapy. Knowledge of activity-determining segments in the structure is valuable in the protein engineering of glutathione transferase for enhanced or suppressed activity.

    Full Text Available SUMMARY. Introduction: Idiopathic pulmonary fibrosis (IPF is characterized by progressive deterioration of lung function, leading ultimately to death. No pharmacological treatment has been found to stabilize the evolution of the disease, but interferon-g and azathioprine have been used as therapeutic options. Aim: To compare the effectiveness of treatment with interferon-g plus low dose prednisone or azathioprine plus low dose prednisone in patients with IPF. Materials and methods: Patients newly diagnosed with IPF were recruited, 22 in total, of whom 10 received azathioprine plus prednisone and 12 patients received interferon-g plus prednisone for six months. Clinical evaluation, lung function tests, HRCT, bronchoscopy and bronchoalveolar lavage (BAL were performed at baseline and after six months of treatment. Results: All patients were alive after six months of treatment. No statistically significant difference between the two groups was detected regarding clinical deterioration, inflammatory biomarkers such as erythrocyte sedimentation rate (ESR, C-reactive protein (CRP, and BAL cell sub-populations. There was a trend, not statistically significant, towards a greater reduction in forced vital capacity and diffusing capacity for carbon monoxide in the interferon-g group. Conclusion: Interferon-g does not offer any therapeutic advantage over azathioprine as regards the clinical course, lung function tests and BAL cell counts of patients with IPF.

  18. Are we giving azathioprine too late? The case for early immunomodulation in inflammatory bowel disease

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    Inflammatory bowel disease (IBD) includes two entities, Crohn's disease and ulcerative colitis. Both are chronic conditions with frequent complications and surgical procedures and a great impact on patient's quality of life. The thiopurine antimetabolites azathioprine and 6-mercaptopurine are widely used in IBD patients. Current indications include maintenance therapy, steroid-dependant disease, fistula closure, prevention of infliximab immunogenicity and prevention of Crohn's disease recurrence. Surprisingly, the wide use of immunosuppressants in the last decades has not decreased the need of surgery, probably because these treatments are introduced at too late stages in disease course. An earlier use of immunossupressants is now advocated by some authors. The rational includes: (1) failure to modify IBD natural history of present therapeutic approach, (2) demonstration that azathioprine can induce mucosal healing, a relevant prognostic factor for Crohn's disease and ulcerative colitis, and (3) demonstration that early immunossupression has a very positive impact on pediatric, recently diagnosed Crohn's disease patients. We are now awaiting the results of new studies, to clarify the contribution of azathioprine, as compared to infliximab (SONIC Study), and to demonstrate the usefulness of azathioprine in recently diagnosed adult Crohn's disease patients (AZTEC study).

    For almost three decades in many countries azathioprine has been used to treat relapsing-remitting multiple sclerosis. However its efficacy was usually considered marginal and following approval of β interferons for this indication it was no longer recommended as first line treatment, even if presently no conclusive direct β interferon-azathioprine comparison exists. To compare azathioprine efficacy versus the currently available β interferons in relapsing-remitting multiple sclerosis, a multicenter, randomized, controlled, single-blinded, non-inferiority trial was conducted in 30 Italian multiple sclerosis centers. Eligible patients (relapsing-remitting course; ≥2 relapses in the last 2 years) were randomly assigned to azathioprine or β interferons. The primary outcome was annualized relapse rate ratio (RR) over 2 years. Key secondary outcome was number of new brain MRI lesions. Patients (n = 150) were randomized in 2 groups (77 azathioprine, 73 β interferons). At 2 years, clinical evaluation was completed in 127 patients (62 azathioprine, 65 β interferons). Annualized relapse rate was 0.26 (95% Confidence Interval, CI, 0.19–0.37) in the azathioprine and 0.39 (95% CI 0.30–0.51) in the interferon group. Non-inferiority analysis showed that azathioprine was at least as effective as β interferons (relapse RRAZA/IFN 0.67, one-sided 95% CI 0.96; p<0.01). MRI outcomes were analyzed in 97 patients (50 azathioprine and 47 β interferons). Annualized new T2 lesion rate was 0.76 (95% CI 0.61–0.95) in the azathioprine and 0.69 (95% CI 0.54–0.88) in the interferon group. Treatment discontinuations due to adverse events were higher (20.3% vs. 7.8%, p = 0.03) in the azathioprine than in the interferon group, and concentrated within the first months of treatment, whereas in the interferon group discontinuations occurred mainly during the second year.

Results: Azathioprine had a slower onset of action with a statistically significant improvement seen by 6 months (P = 0.016. Cyclophosphamide had a faster onset of action (3 months though there was no statistical difference in the efficacy between the two at the end of 6 months. The (RonT was 33.3-44.4% for azathioprine and 28.8-42.9% for cyclophosphamide at 6 months. Though ELISA had a high sensitivity and specificity for diagnosis, as a tool for assessing therapeutic response a significant decrease was seen only till 3 months. This was restricted to Dsg1 for the azathioprine group and both Dsg3 and Dsg1 levels for the cyclophosphamide group. There were two deaths, both in the cyclophosphamide group. Conclusions: Azathiorpine and cyclophosphamide are equally effective for mucosal and cutaneous disease in pemphigus after 6 months of therapy. Dsg ELISA is useful for diagnosis of pemphigus but is not a useful tool for monitoring response to therapy.

    AIM: To evaluate the role of azathioprine (AZA) in Indian patients with ulcerative colitis over longer duration of time.METHODS: One hundred fifty six patients with ulcerative colitis who were treated with AZA from .January 1995 to December 2003 were reviewed. The indications for its use were as follows: (1) steroid dependent and steroid refractory disease; (2) Azathioprine monotherapy for na(i)ve patients with severe disease; and (3) combination therapy (AZA + sulfasalazine or 5-aminosalicylates) for na(i)ve patients with severe disease. The data included patient and disease demographics, efficacy and toxicity profile of AZA. Patients with a minimum duration of 6 mo use of AZA were included in this report.RESULTS: Of a total of 156 patients treated with AZA,45 were excluded from analysis for the following reasons(follow up less than 6 mo,n = 9; poor follow up,n = 18;adverse affects,n = 18). In steroid refractory/dependent group the mean number of relapses prior to and post initiation of AZA therapy were 3.28 (± 0.81) and 0.94 (±0.29) respectively. Discontinuation of steroids could be accomplished in 12 of the 15 steroid dependent patients.The proportion of patients with sustained remission of 1,2, 3, 4 and 5 years duration were calculated. Eighteen patients experienced adverse effects necessitating withdrawal of AZA (pancreatitis,n = 7; hepatitis,n = 3; gastrointestinal intolerance,n = 2; alopecia,n = 2; and hematological, n = 4) while 13 patients needed dose reduction or temporary withdrawal of the drug.CONCLUSION: Azathioprine is well tolerated and has therapeutic benefits lasting as long as 4 years. Adverse effects such as pancreatitis, hepatitis, cytopenias and gastrointestinal symptoms do occur but are controlled by drug withdrawal only.

    Kara Bradford; David Q Shih

    2011-01-01

    The thiopurine drugs, 6-mercaptopurine (6-MP) and azathioprine, are efficacious in the arsenal of inflammatory bowel disease (IBD) therapy. Previous reports indicate that 6-thioguanine nucleotide (6-TGN) levels correlate with therapeutic efficacy, whereas high 6-methylmercaptopurine (6-MMP) levels are associated with hepatotoxicity and myelotoxicity. Due to their complex metabolism, there is wide individual variation in patient response therein, both in achieving therapeutic drug levels as well as in developing adverse reactions. Several strategies to optimize 6-TGN while minimizing 6-MMP levels have been adopted to administer the thiopurine class of drugs to patients who otherwise would not tolerate these drugs due to side-effects. In this report, we will review different approaches to administer the thiopurine medications, including the administration of 6-mercaptopurine in those unsuccessfully treated with azathioprine; co-administration of thiopurine with allopurinol; co-administration of thiopurine with anti-tumor necrosis factor a; 6-TGN administration; desensitization trials; and split dosing of 6-MP.

    Full Text Available The immunosuppressant azathioprine (AZA is widely used in the treatment of inflammatory bowel disease (IBD for both inducing and maintaining remission. However, the adverse effects of AZA can often necessitate a dose reduction or discontinuation. Bone marrow suppression is one of the most serious complications with AZA treatment. On the other hand, some reports have suggested that neutropenia during AZA therapy reduced the relapse rates of IBD patients, and there have been some cases where eradication of the sensitized leukocytes by leukapheresis or bone marrow transplantation improved the IBD, which may explain the relevant role of neutropenia in controlling disease activity. This report describes the case of a 22-year-old male patient who had Crohn’s colitis and complicated perianal fistulas that required immunosuppression; he achieved endoscopically determined remission and showed accelerated mucosal healing as well as clinical remission following the AZA-induced pancytopenia.

    Sweet's syndrome (SS) is a dermatosis with systemic symptoms characterized by tender, red nodules or papules, occasionally covered with vesicles, pustules or bullae, usually affecting the upper limbs, face and neck. SS is frequently observed in patients with leukemia or connective tissue diseases, while it is rather seldom in patients with inflammatory bowel disease. The exact pathogenesis of SS is only partially understood. We report the case of a 50-year-old patient with indeterminate colitis, presenting with a febrile diffuse papulopustular and necrotizing skin eruption that healed with significant scarring and appeared 14 days after onset of treatment with azathioprine. Histological examination revealed the presence of features typical of SS, gene expression analysis very high levels of interleukin-1β (IL-1β) mRNA in lesional skin, and immunohistochemistry high levels of IL-1β at the protein level. SS associated with azathioprine is being increasingly reported and is reviewed herein.

    By using graphene nanosheets decorated with Ag nanoparticles (AgNPs-G) as an effective approach for the surface modification of pyrolytic graphite electrode (PGE), a sensing platform was fabricated for the sensitive voltammetric determination of Azathioprine (Aza). The prepared AgNPs-G nanosheets were characterized using transmission electron microscopy (TEM), X-ray diffraction (XRD), UV–vis and Raman spectroscopy techniques. The electrochemical behavior of Aza was investigated by means of cyclic voltammetry. Comparing to the bare PGE, a remarkable enhancement was observed in the response characteristics of Aza on the surface of the modified electrode (AgNPs-G/PGE) as well as a noticeable decrease in its reduction overpotential. These results can be attributed to the incredible enlargement in the microscopic surface area of the electrode due to the presence of graphene nanosheets together with strong adsorption of Aza on its surface. The effect of experimental parameters such as accumulation time, the amount of modifier suspension and pH of the supporting electrolyte were also optimized toward obtaining the maximum sensitivity. Under the optimum conditions, the calibration curve studies demonstrated that the peak current increased linearly with Aza concentrations in the range of 7 × 10{sup −7} to 1 × 10{sup −4} mol L{sup −1} with the detection limit of 68 nM. Further experiments revealed that the modified electrode can be successfully applied for the accurate determination of Aza in pharmaceutical preparations. - Highlights: • A novel electrochemical sensing platform based on graphene nanosheets decorated with Ag nanoparticles was constructed for determination of Azathioprine. • The prepared modified electrode showed an efficient catalytic role toward the electro-reduction of Azathioprine. • The prepared modified electrode shows a wide linear dynamic range and a nanomolar detection limit for Azathioprine. • The modification procedure provides a

    The development of colorectal cancer in ulcerative colitis is a function of disease duration, with the risk approaching 14% at 25 years. Colitic cancer has become an issue in the last decades, as the availability of effective immune suppressors has reduced resort to curative colectomies. Scrutiny of the available drug options for ulcerative colitis has generated solid evidence of a chemopreventive role of mesalamines. Recent studies on the thiopurines azathioprine and mercaptopurine have unraveled the ability of these drugs to reduce inflammation and influence adaptive immunity by enhancing apoptosis. This evidence, speaking in favor of a chemopreventive role of thiopurines, has not been supported until recently by clinical studies. By contrast, endoscopic and clinical data in our hands have continued to suggest such a role: of a cohort of ulcerative colitis patients treated with azathioprine for 17 years, those on active treatment had no mucosal inflammation on endoscopy and overall none in this cohort developed cancer. This retrospective data have now been validated by cutting-edge information from a prospective nationwide study from an independent group which found a significant chemopreventive effect of azathioprine in those with extended long-standing colitis. Combination of our single-center experience with the data from this large study strongly indicates that the immune modulatory properties of thiopurines can translate into clinically meaningful anti-cancer activity in colitis. These results are likely to influence the medical choices of inflammatory bowel disease caregivers in the decades to come.

    Azathioprine (AZA) is a cytotoxic immunosuppressive drug used in the prevention of rejection in organ transplants and the treatment of auto-immune diseases. However, AZA is haemotoxic causing significant bone marrow depression. The present studies were to characterize the haemotoxicity of AZA in the female CD-1 mouse. In Experiment 1, a dose-ranging study, with AZA gavaged daily for 10 days, clinical evidence of toxicity was evident at 125 mg/kg and above. Experiment 2 was a dose-response study with AZA gavaged daily for 10 days at 40-120 mg/kg. At day 1 after the final dose, AZA induced a dose-related pancytopaenia, reduced femoral marrow cellularity, increases in serum levels of the cytokine fms-like tyrosine kinase 3 ligand, reduction in granulocyte-monocyte colony-forming units and erythroid colonies, and increased bone marrow apoptosis. Histology demonstrated hepatocyte hypertrophy, thymic atrophy, reduced splenic extramedullary haemopoiesis, and reduced cellularity of sternal bone marrow. In Experiment 3, AZA was dosed for 10 days at 100 mg/kg with autopsies at 1, 3, 9, 22, 29, 43 and 57 days postdosing. At 1, 3 and 9 days, haematological parameters reflected changes in Experiment 2. At 22/29 days, many blood parameters were returning towards normal; at 43/57 days, most parameters compared with controls. However, there was some evidence of a persistent (i.e. residual/late-stage) mild reduction in RBC and erythroid progenitor cell counts at day 43/57. We conclude that the CD-1 mouse provides an acceptable model for the haemotoxicity of AZA in man.

  20. Thiopurine drugs azathioprine and 6-mercaptopurine inhibit Mycobacterium paratuberculosis growth in vitro.

    The in vitro susceptibility of human- and bovine-origin Mycobacterium paratuberculosis to the thioupurine drugs 6-mercaptopurine (6-MP) and azathioprine (AZA) was established using conventional plate counting methods and the MGIT 960 ParaTB culture system. Both 6-MP and AZA had antibacterial activity against M. paratuberculosis; isolates from Crohn's disease patients tended to be more susceptible than were bovine-origin isolates. Isolates of Mycobacterium avium, used as controls, were generally resistant to both AZA and 6-MP, even at high concentrations (> or =64.0 microg/ml). Among rapidly growing mycobacteria, Mycobacterium phlei was susceptible to 6-MP and AZA whereas Mycobacterium smegmatis strains were not. AZA and 6-MP limited the growth of, but did not kill, M. paratuberculosis in a dose-dependent manner. Anti-inflammatory drugs in the sulfonamide family (sulfapyridine, sulfasalazine, and 5-aminosalycilic acid [mesalamine]) had little or no antibacterial activity against M. paratuberculosis. The conventional antibiotics azithromycin and ciprofloxacin, used as control drugs, were bactericidal for M. paratuberculosis, exerting their killing effects on the organism relatively quickly. Simultaneous exposure of M. paratuberculosis to 6-MP and ciprofloxacin resulted in significantly higher CFU than use of ciprofloxacin alone. These data may partially explain the paradoxical response of Crohn's disease patients infected with M. paratuberculosis to treatment with immunosuppressive thiopurine drugs, i.e., they do not worsen with anti-inflammatory treatment as would be expected with a microbiological etiologic pathogen. These findings also should influence the design of therapeutic trials to evaluate antibiotic treatments of Crohn's disease: AZA drugs may confound interpretation of data on therapeutic responses for both antibiotic-treated and control groups.

    Tumor-derived and bacterial phosphoantigens are recognized by unconventional lymphocytes that express a Vγ9Vδ2 T cell receptor (Vδ2 T cells) and mediate host protection against microbial infections and malignancies. Vδ2 T cells are absent in rodents but readily populate the human intestine, where their function is largely unknown. Here, we assessed Vδ2 T cell phenotype and function by flow cytometry in blood and intestinal tissue from Crohn's disease patients (CD patients) and healthy controls. Blood from CD patients included an increased percentage of gut-tropic integrin β7-expressing Vδ2 T cells, while "Th1-committed" CD27-expressing Vδ2 T cells were selectively depleted. A corresponding population of CD27+ Vδ2 T cells was present in mucosal biopsies from CD patients and produced elevated levels of TNFα compared with controls. In colonic mucosa from CD patients, Vδ2 T cell production of TNFα was reduced by pharmacological blockade of retinoic acid receptor-α (RARα) signaling, indicating that dietary vitamin metabolites can influence Vδ2 T cell function in inflamed intestine. Vδ2 T cells were ablated in blood and tissue from CD patients receiving azathioprine (AZA) therapy, and posttreatment Vδ2 T cell recovery correlated with time since drug withdrawal and inversely correlated with patient age. These results indicate that human Vδ2 T cells exert proinflammatory effects in CD that are modified by dietary vitamin metabolites and ablated by AZA therapy, which may help resolve intestinal inflammation but could increase malignancy risk by impairing systemic tumor surveillance.

    Background Malignant tumor is the most common complication occurred in transplant recipients. It is widely recognized that immunosuppressive treatments increase the risk of cancer in transplant recipients. The efficacy and safety of rapamycin (RPM) in combination with low-dose calcineurin inhibitor (CNI) in treating 15 renal allograft recipients which developed urothelial carcinoma were observed. Methods Immunosuppressive regimen in all recipients was altered with rapamycin to replace mycophenolate mofetil (MMF) or azathioprine (Aza). The initial loading dosage was 2 mg/d, and the next dosage was 1 mg/d. The dosage of rapamycin was carefully adjusted according to the blood drug level and concentration of the drug was maintained at 4-6 ug/L. In all the 15 patients, the calcineurin inhibitor was reduced down to one third of the original dosage after the rapamycin blood concentration became stable. Surgical treatment and intravesical instillation chemotherapy were carried out in all patients. Recurrence of the tumor was monitored throughout the study. Post-transplant renal function and side effects were also closely monitored. Results Among the 15 patients, 9 had no tumor recurrence in 2 years, 2 had tumor recurrences twice, and 4 had once. There was no acute rejection observed during RPM treatment. Post-transplant renal function in 11 patients was improved, with a decreased creatinine level. Hyperlipoidemia and thrombocytopenia were the most frequent adverse events which responded well to corresponding treatments. Conclusion Among the renal allograft recipients with urothelial carcinoma, combination of rapamycin and low dose calcineurin inhibitor treatment is effective and safe.

Eight weeks' postgrafting medication with cyclosporin A, prednisolone and azathioprine had resulted in survival of 14 out of 15 grafts (93%), compared with 11 out of 14 (79%) in the group treated with cyclosporin A alone. Only 2 out of 13 grafts (15%) survived in placebo-treated animals....... Transplants in the trimedication group displayed distinct cell and neuropil layers and only minimal cellular infiltration by leukocyte common antigen-expressing cells, whereas grafts in cyclosporin A- and placebo-treated groups were densely infiltrated. The results are discussed in relation to the need...... for extended immunosuppressive and antiinflammatory therapies after intracerebral grafting of histoincompatible tissues....

    To assess the impact of cyclosporine on long-term kidney function in transplant patients, we retrospectively analyzed 273 patients on azathioprine and 308 on CsA with graft functioning at 1 year. To balance the length of follow-ups, the observation of patients was cut at 5 years. Actual graft survival rate at 5 years was similar in Aza and CsA (88% vs. 90%). Multivariate analysis in Aza pts showed that proteinuria (P = 0.006) and hypertension at 1 year (P = 0.002) increased the probability of irreversible graft failure by 2.47 and 2.85, respectively. In CsA patients, proteinuria (P = 0.007) and plasma creatinine higher than 2.5 mg/dl (P = 0.006) increased the probability of graft failure by 5.12 and 6.48, respectively. In both Aza and CsA patients with a follow-up of at least 5 years, plasma creatinine levels were significantly worse at 5 years vs. 1 year (P = 0.004). The slopes of plasma creatinine values plotted vs time were not different between the two groups. Chronic graft dysfunction (CGD) was defined as a stable increase of plasma creatinine of at least 50% above stable values at 1 year. The probability of remaining without CGD at 5 years was 75% for CsA and 80% for Aza patients (P = N.S.). Multivariate analysis of factors influencing the development of CGD showed that hypertension (P = 0.003) and proteinuria at 1 year (P = 0.081) increased the probability of developing CGD by 2.19 and 1.76, respectively, in Aza, while in CsA patients proteinuria only (P = 0.063) increased the probability of developing CGD by 2.29. Graft survival at 5 years after development of CGD was 34% in Aza and 53% in CsA-treated patients. These data confirm that in the long-term CsA does not cause a higher prevalence of CGD and show that, in the presence of CGD, CsA has a superior protective effect than Aza.

    AIM: To evaluate the efficacy and the safety of aza-thioprine (AZA) and buthionine sulfoximine (BSO) by localized application into HepG2 tumor in vivo.METHODS: Different hepatoma and colon carcinoma cell lines (HepG2, HuH7, Chang liver, LoVo, RKO, SW-48, SW-480) were grown in minimal essencial medium supplemented with 10% fetal bovine serum and 1% antibiotic/antimycotic solution and maintained in a humidified 37'C incubator with 5% CO2. These cells were pretreated with BSO for 24 h and then with AZA for different times. We examined the effects of this combination on some proteins and on cellular death. We also studied the efficacy and the safety of AZA (6 mg/kg per day) and BSO (90 mg/kg per day) in HepG2 tumor growth in vivo using athymic mice. We measured safety by serological markers such as amino-transferases and creatine kinase.RESULTS: The in vitro studies revealed a new mechanism of action for the AZA plus BSO combination in the cancer cells compared with other thiopurines (6-mer-captopurine, 6-methylmercaptopurine, 6-thioguanine and 6-methylthioguanine) in combination with BSO. The cytotoxic effect of AZA plus BSO in HepG2 cells resulted from necroptosis induction in a mitochondrial-de-pendent manner. From kinetic studies we suggest that glutathione (GSH) depletion stimulates c-Jun amino-ter-minal kinase and Bax translocation in HepG2 cells with subsequent deregulation of mitochondria (cytochrome c release, loss of membrane potential), and proteolysis activation leading to loss of membrane integrity, release of lactate dehydrogenase and DNA degradation. Some of this biochemical and cellular changes could be reversed by N-acetylcysteine (a GSH replenisher). In vivo studies showed that HepG2 tumor growth was inhibited when AZA was combined with BSO.CONCLUSION: Our studies suggest that a combination of AZA plus BSO could be useful for localized treatment of hepatocellular carcinoma as in the currently used transarterial chemoembolization method.

    Full Text Available Abstract Background Azathioprine is used as an immunosuppressant in canine immune-mediated hemolytic anemia (IMHA, but this potentially toxic and carcinogenic drug has not been proven to be beneficial. The aim of this study was to determine the difference in outcome and survival of dogs with idiopathic IMHA treated with a protocol that included azathioprine and prednisolone versus a protocol that included prednisolone alone. Results The study included 222 dogs with a hematocrit lower than 0.30 L/L and either a positive Coombs' test or spherocytosis and no evidence of diseases that could trigger IMHA. The clinical and laboratory data at the time of diagnosis and the response to therapy and survival were compared in dogs treated according to the prednisolone and azathioprine protocol (AP protocol; n = 149 and dogs treated according to the prednisolone protocol (P protocol; n = 73. At study entry, the two groups were comparable, except that thrombocyte counts were significantly lower and clinical signs had been present significantly longer in the AP protocol group. No significant difference in survival was found between the two groups: the 1-year survival was 64% (95% CI 54 - 77% in the P protocol group and 69% (95% CI 59-80% in the AP protocol group, respectively. Conclusions Azathioprine would appear not to be beneficial as standard treatment for all cases of IMHA; however, a blinded, randomized clinical trial is needed to establish whether outcome is different with the two treatment protocols.

    Hepatoblastoma is a primary liver cancer that affects children, due to the sensitivity of this tumor to insulin-like growth factor 1 (IGF-1). In this paper we show that azathioprine (AZA) is capable of inhibiting IGF1-mediated signaling cascade in HepG2 cells. The efficiency of AZA on inhibition of proliferation differs in the evaluated cell lines as follows: HepG2 (an experimental model of hepatoblastoma) > Hep3B (derived from a hepatocellular carcinoma) > HuH6 (derived from a hepatoblastoma) ≫ HuH7 (derived from a hepatocellular carcinoma) = Chang Liver cells (a non-malignant cellular model). The effect of AZA in HepG2 cells has been proven to derive from activation of Ras/ERK/TSC2, leading to activation of mTOR/p70S6K in a sustained manner. p70S6K phosphorylates IRS-1 in serine 307 which leads to the uncoupling between IRS-1 and p85 (the regulatory subunit of PI3K) and therefore causing the lack of response of HepG2 to IGF-1. As a consequence, proliferation induced by IGF-1 is inhibited by AZA and autophagy increases leading to senescence of HepG2 cells. Our results suggest that AZA induces the autophagic process in HepG2 activating senescence, and driving to deceleration of cell cycle but not to apoptosis. However, when simultaneous to AZA treatment the autophagy was inhibited by bafilomycin A1 and the degradation of regulatory proteins of cell cycle (e.g. Rb, E2F, and cyclin D1) provoked apoptosis. In conclusion, AZA induces resistance in hepatoblastoma cells to IGF-1, which leads to autophagy activation, and causes apoptosis when it is combined with bafilomycin A1. We are presenting here a novel mechanism of action of azathioprine, which could be useful in treatment of IGF-1 dependent tumors, especially in its combination with other drugs. - Highlights: • Azathioprine activated Ras/ERK/TSC-2/mTOR/p70S6K signaling pathway in HepG2 cells. • Azathioprine inhibited IGF-1-mediated signaling cascade. • Azathioprine induced autophagy leading to cell cycle

    Full Text Available Hepatocellular carcinoma most commonly occurs in patients with underlying liver disease or cirrhosis. We describe a case of hepatocellular carcinoma in a 34-year-old man with Crohn’s disease treated with azathioprine and infliximab. The patient had no history of liver disease and a complete autoimmune and viral workup was unremarkable. Unfortunately, the patient developed widespread metastatic disease and passed away 5 months after his initial diagnosis. The mechanism of hepatocellular carcinoma in patients’ with Crohn’s disease is poorly understood and may include both autoimmunity and treatment-related complications. Previous case reports suggest the possibility of a concerning association between azathioprine therapy and the development of hepatocellular carcinoma in patients with Crohn’s disease. Clinicians may consider early imaging in patients with Crohn’s disease presenting with concerning symptomatology or abnormal liver enzymes, especially in those being treated with azathioprine alone or in combination with infliximab. Future research may help to uncover additional risk factors for this exceedingly rare diagnosis in this patient population.

    In the present study we demonstrate that azathioprine (AZA) inhibits vaccinia virus (VV) replication in both BSC-40 and RAG cell lines, acting on different stages of virus cycle. In BSC-40 cells, early protein synthesis was not significantly affected, but late gene expression was severely impaired. In RAG cells all stages of gene expression were completed during synchronous infection in the presence of the drug. The onset of DNA replication was not affected in RAG cells, but a severe inhibition was observed in BSC-40 cells. Electron microscopic analysis of VV-infected RAG cells treated with AZA revealed brick-shaped particles presenting abnormal definition of the internal structure. Purified virions from AZA-treated RAG cells presented several modifications of the protein content, a lesser amount of DNA, and a lower PFU:particle ratio. Our results suggest that in VV-infected RAG cells AZA interfered with virus morphogenesis, whereas in BSC-40 cells the replicative cycle was inhibited at the DNA replication stage.

    Background and Aims: Azathioprine [AZA] is recommended for maintenance of steroid-free remission in inflammatory bowel disease IBD. The aim of this study has been to establish the incidence and severity of AZA-induced pancreatitis, an idiosyncratic and major side effect, and to identify specific risk factors. Methods: We studied 510 IBD patients [338 Crohn’s disease, 157 ulcerative colitis, 15 indeterminate colitis] with initiation of AZA treatment in a prospective multicentre registry study. Acute pancreatitis was diagnosed in accordance with international guidelines. Results: AZA was continued by 324 [63.5%] and stopped by 186 [36.5%] patients. The most common cause of discontinuation was nausea [12.2%]. AZA-induced pancreatitis occurred in 37 patients [7.3%]. Of these: 43% were hospitalised with a median inpatient time period of 5 days; 10% had peripancreatic fluid collections; 24% had vomiting; and 14% had fever. No patient had to undergo nonsurgical or surgical interventions. Smoking was the strongest risk factor for AZA-induced acute pancreatitis [p < 0.0002] in univariate and multivariate analyses. Conclusions: AZA-induced acute pancreatitis is a common adverse event in IBD patients, but in this study had a mild course in all patients. Smoking is the most important risk factor. PMID:26468141

    Full Text Available Effects of carbon tetrachloride (CCl4 and azathioprine (AZP on the evolution of hyperplastic liver nodules and foci and hepatocellular carcinoma (HCC were tested in short- and long-term in vivo experiments. In diethylnitrosamine (DEN-treated rats, which were fed a N-2-fluorenylacetamide (FAA-containing diet and additionally treated with repeated CCl4 injections, gamma-glutamyl transpeptidase (gamma-GTP-positive hyperplastic nodules were markedly developed in the 8th week of the experiment. However, their number and area in liver sections were remarkably small in DEN-treated rats fed a diet containing both FAA and AZP. Increased area of gamma-GTP-positive foci was also observed in the 12th week in DEN-injected rats fed a choline-devoid died alone or treated with repeated doses of CCl4 alone. Hepatocellular carcinoma in DEN-injected rats treated with both FAA and CCl4 was first detected in the 21st week, and the incidence up to the 36th week was very high. However, no hepatocellular carcinoma developed in DEN-injected rats treated with both FAA and AZP. The increased activity of liver aniline hydroxylase observed 12 h after the administration of FAA, AZP or DEN alone was not observed when AZP was administered simultaneously with FAA to DEN-injected rats. The mechanisms of the effects of CCl4 and AZP on hepatocarcinogenesis are discussed with special reference to drug interaction.

    By using graphene nanosheets decorated with Ag nanoparticles (AgNPs-G) as an effective approach for the surface modification of pyrolytic graphite electrode (PGE), a sensing platform was fabricated for the sensitive voltammetric determination of Azathioprine (Aza). The prepared AgNPs-G nanosheets were characterized using transmission electron microscopy (TEM), X-ray diffraction (XRD), UV-vis and Raman spectroscopy techniques. The electrochemical behavior of Aza was investigated by means of cyclic voltammetry. Comparing to the bare PGE, a remarkable enhancement was observed in the response characteristics of Aza on the surface of the modified electrode (AgNPs-G/PGE) as well as a noticeable decrease in its reduction overpotential. These results can be attributed to the incredible enlargement in the microscopic surface area of the electrode due to the presence of graphene nanosheets together with strong adsorption of Aza on its surface. The effect of experimental parameters such as accumulation time, the amount of modifier suspension and pH of the supporting electrolyte were also optimized toward obtaining the maximum sensitivity. Under the optimum conditions, the calibration curve studies demonstrated that the peak current increased linearly with Aza concentrations in the range of 7 × 10(-7) to 1 × 10(-4)mol L(-1) with the detection limit of 68 nM. Further experiments revealed that the modified electrode can be successfully applied for the accurate determination of Aza in pharmaceutical preparations.

    Despite the accumulation of positive data, the role of azathioprine (AZA) in the maintenance of remission of ulcerative colitis is still controversial. We looked at the follow-up of the ulcerative colitis patients who, after responding to either steroids or cyclosporin (CsA), received AZA at our referral center for over a decade. The 39 patients (29 m/10f) were treated between 1991 and 2007. Twenty-five of them had responded to CsA, the remaining 14 to corticosteroids. AZA was usually overlapped with either of the two agents at the initial dose of 2mg/kg/day. The definitions of remission, relapse, and AZA toxicity followed commonly agreed criteria. The median duration of the AZA treatment was 14 months (<1-201). Fifty-two percent and 14%, respectively, of the CsA and the steroid responders needed surgery (overall rate=38%). The figures were 32 and 15 at the first year. The majority of the patients had 1-2 relapses often in connection with withdrawal of AZA; only 3 of these relapsers needed hospitalization. AZA caused toxicity in 16/39 (41%) patients, requiring withdrawal in 23% of the cases; leukopenia (17%) and hepatitis/cholestasis (10%) ranked first and second for frequency. All of the patients in whom AZA was stopped (or reduced) relapsed. In conclusion, the 1-year colectomy rates compare favorably with the figures reported by the literature. By contrast, the toxicity rates were higher than expected. Failure to genotype or to use escalating AZA doses can only be hypothesized as causes.

    Full Text Available Chronic allograft nephropathy (CAN remains a major cause of graft failure over the long term, second only to patient mortality. The main adverse effects of cyclosporine A (CsA include nephrotoxicity, hypertension, symptomatic hyperuricemia, hirsutism, and gum hyperplasia. Available studies among live related donor renal transplants lack adequate information regarding the long-term efficacy and safety of primary CsA-based immunosuppressive regimens. This prospective randomized study is aimed at evaluating the long-term results of CsA-based immunosuppressive protocols in live-donor kidney transplantation. The follow-up data of 444 renal transplant recipients operated at the Urology and Nephrology Center, Mansoura University, prior to 1996 were reviewed. Primary immuno-suppressive protocols included: steroids and azathioprine (group I, 130 cases; steroids and CsA (group II, 75 cases; and steroids, CsA, and azathioprine (group III, 239 cases. Only adult primary renal transplant recipients with age ranging between 18 and 60 years and one haplotype HLA mismatch with the donor were included. All patients received kidneys from living related donors with previous donor non-specific blood transfusions. The percentage of cases with chronic rejection was significantly higher in group III. Living cases with graft failure were significantly higher in group III, whereas mortality was significantly higher in group I. Diabetic patients and those with serious bacterial infections were significantly more prevalent in group II. Hypertensive patients were significantly more common in groups I and II. Liver disease was more prevalent among patients in group III. Our study suggests that the long-term results of treatment with steroids and azathioprine are satisfactory in live related donor kidney transplant recipients. Chronic rejection was significantly higher in patients in group III, possibly due to the risk of CsA nephrotoxicity. Groups with CsA-based protocols

    Cyclosporin has improved graft survival after renal transplantation, but cyclosporin nephrotoxicity is a severe clinical problem. Conversion from cyclosporin to azathioprine 1 year after transplantation might improve long-term graft survival by avoidance of cyclosporin nephrotoxicity. After treatment with cyclosporin and prednisolone during the first year after renal transplantation, 106 patients were consecutively randomized to treatment with either azathioprine and prednisolone or cyclosporin and prednisolone in a prospective, controlled study during the following 5 years, i.e. 6 years after transplantation. Actuarial estimates of graft survival rates after inclusion in the study were obtained by the product-limit method of Kaplan-Meier, and the Mantel-Cox log rank test was used to compare the two treatment regimens. When the end-points in the analyses were cessation of graft function or withdrawal of immunosuppressive treatment due to side-effects, and when patients alive with graft function or who had died with a functioning graft were treated as censored observations, graft survival 5 years after inclusion in the study was 57.7 +/- 5.2% in the total material and was the same in both the azathioprine group (52.4 +/- 7.7%) and the cyclosporin group (63.3 +/- 6.7%) (log rank = 0.40, P = 0.53). When cessation of graft function was the only end-point, graft survival 5 years after inclusion in the study was 73.7 +/- 5.2% for the total material with no significant differences between the two groups (log rank = 0.58, P = 0.45).(ABSTRACT TRUNCATED AT 250 WORDS)

The treatment is based on corticosteroids and cytotoxic drugs, under special conditions. We describe the case of a 7-year-old girl with IPH who achieved partial clinical remission with high doses of corticosteroids. However, the treatment had to be discontinued because the patient developed Cushing's syndrome. Treatment was started with an azathioprine-corticosteroid combination and then changed to azathioprine alone, which was maintained for four years, with excellent results.

    A novel modified glassy carbon electrode with a film of nanodiamond-graphite/chitosan is constructed and used for the sensitive voltammetric determination of azathioprine (Aza). The surface morphology and thickness of the film modifier are characterized using atomic force microscopy. The electrochemical response characteristics of the electrode toward Aza are investigated by means of cyclic voltammetry. The modified electrode showed an efficient catalytic role for the electrochemical reduction of Aza, leading to a remarkable decrease in reduction overpotential and enhancement of the kinetics of the electrode reaction with a significant increase of peak current. The effects of experimental variables, such as the deposited amount of modifier suspension, the pH of the supporting electrolyte, the accumulation potential and time were investigated. Under optimal conditions, the modified electrode showed a wide linear response to the concentration of Aza in the range of 0.2-100 muM with a detection limit of 65 nM. The prepared modified electrode showed several advantages: simple preparation method, high stability and uniformity in the composite film, high sensitivity, excellent catalytic activity in physiological conditions and good reproducibility. The modified electrode can be successfully applied to the accurate determination of trace amounts of Aza in pharmaceutical and clinical preparations.

    Retrospective and prospective cohort studies suggest that central nervous system involvement occurs in approximately 0.5 % of patients with advanced Hodgkin's lymphoma. The isolated primary intracranial manifestation of Hodgkin's lymphoma is an extremely rare finding, with few cases reported in the literature. Little is known about the optimal treatment and prognosis of these tumors. Here, we present a case report with a review of the literature. A 47-year-old Caucasian man with persistent frontal headache and unspecific vertigo for half a month was diagnosed with nodular space-occupying lesions in the cerebellum. His medical history included multiple sclerosis, which was treated for 20 years with the immunosuppressive drug azathioprine. Further staging revealed no additional lesions suspected of being malignant. The patient underwent total tumor resection. Immunohistopathological examination showed Epstein-Barr virus-associated classic Hodgkin's lymphoma. Diagnostic bone marrow punction excluded lymphoma involvement of the bone marrow. The patient had no B symptoms. Consequently, the patient was classified as having stage I{sub E}A disease according to the Modified Ann Arbor Classification of Hodgkin Lymphoma and received systemic chemotherapy followed by radiation therapy for the former cerebellar tumor region. He was in complete clinical remission at the last follow-up 9 months after the initial diagnosis. This case report and literature review suggest that multimodal treatment leads to a remarkable clinical outcome in Hodgkin's lymphoma with intracranial involvement. (orig.)

    AIM: To assess the combined effect of disease phenotype, smoking and medical therapy [steroid, azathioprine (AZA), AZA/biological therapy] on the probability of disease behavior change in a Caucasian cohort of patients with Crohn's disease (CD). METHODS: Three hundred and forty well-characterized, unrelated, consecutive CD patients were analyzed (M/F: 155/185, duration: 9.4 ± 7.5 years) with a complete clinical follow-up. Medical records including disease phenotype according to the Montreal classification, extraintestinal manifestations, use of medications and surgical events were analyzed retrospectively. Patients were interviewed on their smoking habits at the time of diagnosis and during the regular follow-up visits. RESULTS: A change in disease behavior was observed in 30.8% of patients with an initially non-stricturing, non-penetrating disease behavior after a mean disease duration of 9.0 ± 7.2 years. In a logistic regression analysis corrected for disease duration, perianal disease, smoking, steroid use, early AZA or AZA/ biological therapy use were independent predictors of disease behavior change. In a subsequent Kaplan-Meier survival analysis and a proportional Cox regression analysis, disease location ( P = 0.001), presence of perianal disease ( P < 0.001), prior steroid use ( P = 0.006), early AZA ( P = 0.005) or AZA/biological therapy ( P = 0.002), or smoking ( P = 0.032) were independent predictors of disease behavior change. CONCLUSION: Our data suggest that perianal disease, small bowel disease, smoking, prior steroid use, early AZA or AZA/biological therapy are all predictors of disease behavior change in CD patients.

    A total of 25 renal transplant recipients, treated solely with prednisolone and azathioprine, were investigated in a randomized, double-blind, placebo-controlled, cross-over study. The effect of a single oral dose of felodipine 5 mg or placebo on: glomerular filtration rate (GFR); renal plasma flow (RPF); renal vascular resistance (RVR); renal tubular sodium and water handling, measured by the lithium clearance technique; plasma levels of angiotensin II (AngII), aldosterone (Aldo), atrial natriuretic factor (ANF) and arginine vasopressin (AVP); blood pressure (BP), and heart rate (HR) was studied before, during, and after an intravenous infusion of cyclosporin (CyA). Three consecutive clearance periods were performed, each lasting 1 h. During the second period, CyA (0.75 mg kg-1 body weight) was infused. Before infusion of CyA, felodipine caused a significant rise (6.7%) in RPF and lowered RVR, but did not change GFR significantly. The rise in RPF was abolished by infusion of CyA. After infusion, both GFR (7.8%) and RPF (9.4%) were significantly higher and RVR lower after felodipine than after placebo. Proximal tubular output and total sodium excretion were higher on the felodipine day before and after, but not during CyA infusion. In all three periods felodipine reduced both systolic and diastolic BP. In conclusion, a single dose of felodipine increases RPF and decreases blood pressure in renal transplant recipients not treated with CyA. Although some of these changes are abolished by an acute intravenous infusion of CyA, the effects of felodipine are present again also during the 1st hour after the infusion and thereby indicate at least in part some renal protective effect of felodipine. It is suggested that a higher dose of felodipine might also have been preventive against CyA renal side-effects during the acute infusion.

    The human Dialyzed Leukocyte Extract (DLE) is a heterogeneous mix of oligopeptides of assays exist: E-rosette test, induction of delayed type hypersensitivity in mice, leukocyte migration and IFN-γ secretion. The animal-origin materials and in vivo assays convey a considerable logistic, ethic and economic burden, meanwhile the available in vitro assays have been reported with limited reproducibility and sometimes contradictory results. Here we are reporting a new DLE biological activity cell-based assay. The A20 and Jurkat cell lines were treated with (+Aza) or without (-Aza) azathioprine, DLE (+DLE) or both (+Aza/+DLE). After 72h, the cell proliferation was analyzed by the MTT or BrdU incorporation assays. In +Aza/+DLE treated cells, we observed a significant higher proliferation, when compared with +Aza/-DLE. In the absence of Aza, cells did not present any proliferation difference between -DLE or +DLE treatments. Both assays, MTT and BrdU showed similar results, being the MTT test more cost effective and we select it for validation as DLE biological assay using Jurkat cells only. We tested three different lyophilized DLE batches and we found consistent results with acceptable assay reproducibility and linearity. The DLE capacity for rescuing Jurkat cell proliferation during +Aza treatment was consistent using different liquid and lyophilized DLE batches, presenting also consistent chromatographic profiles. Finally, DLE treatment in Jurkat cells did not result into significant IL-2 of IFN-γ secretion, and known lymphocyte proliferative drugs failed to rescue Jurkat cells viability in presence of +Aza, as +DLE treatment did in our MTT assay. In conclusion, our new cell-based MTT assay has excellent DLE biological activity consistency, robustness and is cost effective, presenting important advantages over previous DLE activity in vitro and in vivo assays.

    Full Text Available Os nucleotídeos de tioguanina (6-TGN, metabólitos ativos da azatioprina (AZA e da 6-mercaptopurina (6-MP, atuam como antagonistas das purinas, inibindo as sínteses de DNA, RNA e a protéica, e induzindo à citotoxicidade/imunossupressão. A enzima geneticamente determinada, tiopurina metiltransferase (TPMT, está envolvida no metabolismo desses agentes e, hipoteticamente, determina a resposta clínica às tiopurinas. A baixa atividade dessa enzima diminui a metilação das tiopurinas, resultando em potencial sobredose, enquanto altos níveis de TPMT levam à superprodução do metabólito tóxico 6-metilmercaptopurina (6-MMP e à não-efetividade terapêutica da AZA e da 6-MP. Várias mutações no gene da TPMT têm sido identificadas e correlacionadas com fenótipos de baixa atividade. Neste artigo, também se discute a monitoração terapêutica desses fármacos por meio da medida dos níveis de 6-TGN intra-eritrocitários, os quais se correlacionam com imunossupressão e mielotoxicidade. Já a 6-MMP está diretamente relacionada com hepatotoxicidade.

The genetically determined thiopurine methyltransferase enzyme (TPMT is involved in the metabolism of these agents and, theoretically, determines the clinical response to thiopurines. Low activity of this enzyme decreases the methylation of thiopurines, what results in potential overdosing, whereas high TPMT status leads to overproduction of toxic metabolite 6-methilmercaptopurine (6-MMP and ineffectiveness of AZA and 6-MP. Several mutations in the TPMT gene have been identified and correlated with low activity phenotypes. In this

However, studies examining their effectiveness in routine practice among diverse patient populations are lacking. Among a cohort of new users of 6MP/AZA, we described treatment patterns and changes in subsequent therapy. Methods: Using the Truven Health Analytics databases, we identified all individuals diagnosed with CD and initiating 6-MP/AZA monotherapy from 2001–2008 (n=3,657. We estimated the proportion of CD patients remaining on 6-MP/AZA monotherapy, using Kaplan–Meier methods, and identified predictors of treatment noncontinuation, using multivariable Cox regression. Among the “noncontinuers,” we described subsequent patterns of maintenance therapy and summarized the diagnosis and procedure codes and prescription drug claims preceding treatment discontinuation. Results: The 1-year 6-MP/AZA treatment continuation rate was 42%. Children (age ≤18 years and individuals with no prior anti-tumor necrosis factor (TNF use were more likely to continue 6-MP/AZA, while those dispensed more (>4 outpatient prescriptions for any drug before initiation of 6-MP/AZA were less likely to continue maintenance treatment. Overall, 1,128 (39% and 105 (4% individuals experienced a clinical event potentially indicating active disease or 6-MP/AZA-intolerance prior to discontinuation, respectively. Most patients discontinued therapy; among the remaining patients who failed to continue 6-MP/AZA, most augmented with an anti-TNF. Conclusion: Most patients initiating 6-MP

  3. Harmful effects of the azathioprine metabolite 6-mercaptopurine in vascular cells: induction of mineralization.

    Directory of Open Access Journals (Sweden)

    Jasmin Prüfer

    Full Text Available Vascular mineralization contributes to the high cardiovascular morbidity and mortality in patients who suffer from chronic kidney disease and in individuals who have undergone solid organ transplantation. The immunosuppressive regimen used to treat these patients appears to have an impact on vascular alterations. The effect of 6-mercaptopurine (6-MP on vascular calcification has not yet been determined. This study investigates the effect of 6-MP on vascular mineralization by the induction of trans-differentiation of rat vascular smooth muscle cells in vitro. 6-MP not only induces the expression of osteo-chondrocyte-like transcription factors and proteins but also activates alkaline phosphatase enzyme activity and produces calcium deposition in in vitro and ex vivo models. These processes are dependent on 6-MP-induced production of reactive oxygen species, intracellular activation of mitogen-activated kinases and phosphorylation of the transcription factor Cbfa1. Furthermore, the metabolic products of 6-MP, 6-thioguanine nucleotides and 6-methyl-thio-inosine monophosphate have major impacts on cellular calcification. These data provide evidence for a possible harmful effect of the immunosuppressive drug 6-MP in vascular diseases, such as arteriosclerosis.

    Sublethal irradiation of BALB/c mice 4 hours prior to inoculation with 5 {times} 10(4) virulent Brucella abortus, caused significant (P less than 0.01) reductions in bacterial numbers in comparison with numbers in unirradiated controls. Numbers of brucellae in the spleen were significantly lower by 5 days after inoculation and decreased thereafter, so that at 2 and 3 weeks after inoculation, there were up to 1,000-fold fewer organisms in the spleen of irradiated mice. The number of brucellae in the spleen increased in irradiated mice thereafter. The course of events in the liver was similar, but developed more slowly, and peak differences in bacterial numbers were about 1 log less. These phenomena were not attributable to differences in implantation of brucellae in the liver or spleen, nor to an abnormal distribution of organisms in other organs of irradiated mice. Irradiation of mice during the plateau phase of infection also resulted in significant (P less than 0.05) reductions in bacterial counts in the spleen during the succeeding 4 weeks. Macrophage activation in the spleen, measured by a Listeria monocytogenes-killing assay, was significantly (P less than 0.01) increased by irradiation alone at 1 week after inoculation and at that time was significantly (P less than 0.01) greater in B abortus-infected, irradiated mice than in B abortus-infected controls. Histologic, cytologic, and immunologic studies revealed that the decrease in numbers of organisms between 1 and 2 weeks after inoculation in irradiated mice occurred at a time when their immune response to B abortus was suppressed and when numbers of neutrophils and monocytes infiltrating the spleen were significantly (P less than 0.01) diminished.

    Severe forms of pemphigus vulgaris (PV) that are resistant to standard treatment present a life-threatening disease with a mortality of 5-10%. The treatment is usually individualized. The most popular procedures used today include intravenous applications of immunoglobulins and rituximab. Currently the common use of pulse corticosteroids, often in first-line treatment, is being neglected. This particular case documented the severity of the disease and also the need for combined and comprehensive care, in which corticosteroid pulse therapy still plays an important role.

    The authors report their experience using cyclosporine-A (CsA) in renal transplant patients. When compared with azathioprine/prednisone, CsA contributed significantly to a better graft and patient survival, either if used associated with prednisone of with azathioprine plus prednisone. CsA was also used in substitution to azathioprine in patients with hepatopathy attributed to azathioprine toxicity. The initial results are promising. The association of CsA and azathioprine with corticosteroids withdrawal was used as an attempt to allow normal growth in children. This seems to be the best choice of treatment for children. Careful monitoring of CsA blood levels avoids, or at least, minimizes nephrotoxicity. To achieve therapeutic CsA levels, patients with liver damage need lower, while children need higher oral CsA doses. To summarise: when CsA in carefully used, it is an excellent immunosuppressive drug.

    2012-09-01

    Bullous pemphigoid is a rare, autoimmune blistering disease. Its clinical presentation is tense blisters that may arise on normal-appearing or erythematous skin. Bullous pemphigoid refractory to systemic corticosteroids in combination with immunosuppressants such as azathioprine and mycophenolate mofetil may benefit from adjuvant high-dose intravenous immunoglobulin (IVIg). We describe a particular case with an unusual clinical presentation unresponsive to systemic corticosteroids plus azathioprine, in which the addition of high-dose IVIg was successful. The combined therapy of systemic corticosteroids and azathioprine plus high-dose IVIg can be an option in refractory cases due to its efficiency and tolerability.

The patients were divided into three groups: (I) cyclosporin treated, (II) azathioprine treated, and (III) azathioprine treated patients with chronic rejection. The platelet function in the renal transplant patients was normal and there was no difference between groups I and II. The specific activity of protein C was decreased in patients after renal transplantation and decreasing protein C activity and progressive renal failure was found to be positively correlated in the azathioprine treated groups.

    Full Text Available Nongranulomatous ulcerative jejunoileitis (NGUJI is a rare, often fatal disorder that produces multiple nonmalignant small bowel ulcerations. A 55-year-old woman with presumed celiac disease presented with steroid-refractory diarrhea, weight loss and abdominal pain. A laparotomy was performed to exclude the possibility of a lymphomatous disorder, and multiple nonmalignant small bowel ulcerations were discovered. Despite a combination of treatment with total parenteral nutrition (TPN and prednisone 30 mg/day she continued to deteriorate. The addition of azathioprine to her treatment regimen resulted in marked clinical and biochemical improvement. Her enteroscopy normalized, and she was able to discontinue TPN and reduce her steroid requirements. Although azathioprine has been used occasionally to treat refractory sprue, there have been no reports of its use in NGUJI. In this case, azathioprine played a key role in the management of NGUJI and should be considered a treatment option for patients with this disorder.

  2. Is there a benefit from the concomitant use of immunosupression with anti-TNF in Crohn's disease; heads or tails?

    2009-09-01

    Over the last some years the increasing knowledge on the pathogenesis of Crohn's disease led to the development of a number of biological agents targeting specific molecules involved in gut inflammation, first of all TNF-alpha and its receptors. Infliximab, adalimumab and certolizumab have been successful in inducing and maintaining remission in Crohn's disease at both short and long term. This was recently confirmed by a Cochrane meta-analysis and also open label extension follow-up and cohort studies. Emerging new data however indicate that combination therapy with infliximab-azathioprine appears to have added benefit in inducing steroid-free remission and mucosal healing than either infliximab or azathioprine alone in azathioprine-naïve patients with early disease. Similarly the combination of steroids induction and infliximab was efficacious in luminal Crohn's disease. In contrast, there seems to be no synergism between methotrexate and infliximab. It is also less clear whether it is beneficial to use short or long-term infliximab-azathioprine combination in patients who previously failed therapy with azathioprine. In contrast, combination may potentially be associated with increased risk for infection and cancer. In case control-studies, especially the combination of steroids and anti-TNF and older age increased the risk for infectious complications, while scattered case reports point to the potentially increased risk of a rare form of non-Hodgkin's lymphoma (Hepatosplenic T cell lymphoma) with the use of azathioprine-anti-TNF combination. The aim of this review is to summarize the benefits and risks for the use combination therapy with TNF-alpha inhibitors in the treatment of Crohn's disease.

    Azathioprine has been extensively used in the management of inflammatory bowel diseases. It might cause pancreatic damage in the form of either asymptomatic elevation in serum amylase/lipase or overt acute pancreatitis. Here we report the case of a 61-year-old patient with ulcerative colitis who had been treated with azathioprine for three years, achieving clinical remission. During treatment he presented an asymptomatic elevation of serum pancreatic enzymes, without any signs of pancreatitis at imaging. This evidence brought us to reassess the drug dosage, without achieving a normalization of biochemical analysis. Autoimmune pancreatitis was excluded. One year after the suspension of azathioprine, we still face persistent high levels of amylase/lipase. Normalization of enzymatic values in patients who develop intolerance to azathioprine, in the form of either asymptomatic elevation in serum amylase/lipase or overt acute pancreatitis, is usually achieved in about two months after stopping drug intake. Asymptomatic elevation in serum pancreatic enzymes in the absence of pancreatic disease is reported in the literature and defined as "Gullo's syndrome," but nobody of the subjects studied had been treated in the past with pancreatotoxic drugs. Might this case be defined as "benign pancreatic hyperenzymemia"?

    A catabolic route for azathioprine involving methylation by thiopurine methyltransferase has been directly implicated in the drug's immunosuppressive efficacy. Since ethnic differences in thiopurine methyltransferase activity have been reported in a study of Lapps, this study compared the distribution of thiopurine methyltransferase activity in erythrocyte lysates from 134 healthy, randomly selected subjects living in Brazil, comprising 39 blacks (i.e. Afro-Brazilians), 33 white subjects, 30 mixed-race subjects, and 32 Brazilian-residing Japanese subjects. The results demonstrated bimodality of thiopurine methyltransferase activity compatible with genetic polymorphism in the white, black and mixed-race groups, but not in the Japanese, who were homogeneously 'fast methylators' (high thiopurine methyltransferase activity). Thiopurine methyltransferase activity was generally higher in Brazilian males than females, and some individuals in the black and mixed-race groups had very high activity. Azathioprine-immunosuppressed transplant patients with thiopurine methyltransferase activity above 35 pmol/h/mgHb have previously been shown to have significantly poorer outcomes. Using this thiopurine methyltransferase value as the cut-off point between 'poor responders' and 'good responders' to azathioprine, 65% of the Japanese, 59% of the black subjects, and 63% of the mixed-race subjects fell into the 'poor responder' category, compared with only 42% of the white group. Interestingly, this approximately 20% difference in azathioprine response corresponds to the racial differences seen in allograft survival.

    We present the case of a 43-year old caucasian male suffering from a condition initially diagnosed as colitis ulcerosa. For 2 years Azathioprine and anti-TNF-alpha antibodies were used for treatment without convincing benefit but with serious adverse events. After the first occurrence of complex accompanying symptoms like oral and scrotal ulcerations, arthritis and scratch-induced skin lesions the differential diagnosis of a Morbus Adamantiades-Behçet with intestinal evolvement was considered. After introduction of a parenteral Ciclosporin medication, which was later switched to Tacrolimus and Azathioprin, a remission could be achieved that lasted for several months. When a drug-induced acute kidney injury occurred, the regime was changed to Golimumab and a delayed but significant improvement was achieved. To separate Morbus Adamantiades-Behçet from inflammatory bowel disease is of some difficulty, demands interdisciplinary cooperation and is the basis for a successful therapy.

    Azathioprine and 6-mercaptopurine remain pivotal therapies for the maintenance of disease remission in patients with Crohn's disease and ulcerative colitis. While thiopurine S-methyltransferase deficiency was the first pharmacogenetic phenomenon to be recognized to influence thiopurine toxicity and reliably predict leukopenia, it does not predict other adverse effects, nor does it explain most cases of thiopurine resistance. In recent years, a number of other genetic polymorphisms have received increasing attention in the literature. In particular, SNPs in NUDT15 and in the class II HLA locus have been shown to predict thiopurine-related leukopenia and pancreatitis. The aim of this review is to provide a concise update of genetic variability which may influence patient response to azathioprine and 6-mercaptopurine.

The patient had been diagnosed with AIH 3 months previously, based on jaundice and impaired liver function tests, and she had been treated with low-dose prednisolone and azathioprine. She presented with malaise, arthritis, a malar rash on the face, and oral ulcers. Laboratory tests revealed a positive ANA/anti-dsDNA test. Liver biopsy showed chronic hepatitis with severe inflammatory activity, in favor of a diagnosis of definite AIH. She fulfilled the international criteria for both SLE and AIH. The clinical symptoms and laboratory findings of SLE improved with ongoing treatment with corticosteroids and azathioprine, accompanied with hydroxychloroquine sulfate. The present case indicates that AIH can be the first manifestation of SLE in children.

    Myasthenia gravis is a disorder of neuromuscular transmission caused by autoimmune mechanisms. We reported a possible association between seropositive myasthenia gravis and Kaposi's sarcoma in a HIV-negative subject and the observed interactions between the treatment regimen for these two conditions. A 62-year-old man came to our attention for ocular myasthenia gravis. He suffered from a classic form of Kaposi's sarcoma since about 1 year. When myasthenic symptoms worsened, the patient was started on prednisone and azathioprine. The patient had a significant worsening of Kaposi's sarcoma, so prednisone and azathioprine were reduced and he was treated with vinblastine, with improvement both in dermatologic than in neurological symptomatology. We propose some considerations: the potential correlation between Kaposi's sarcoma and myasthenia gravis through immunological mechanism; myasthenia gravis as a paraneoplastic manifestation of Kaposi's sarcoma, and the role of an antitumoral agent as a treatment for both the conditions.

    Amoxicillin/clavulanate is associated with liver injury,mostly of a cholestatic pattern. While outcomes are usually benign, progression to cirrhosis and death has been reported. The role of immunosuppressive therapy for patients with a protracted course is unclear. We report the case of an elderly patient who developed prolonged cholestasis secondary to amoxicillin/clavulanate. Vanishing bile duct syndrome was confirmed by sequential liver biopsies. The patient responded to prednisone treatment,but could not be weaned off corticosteroids, even when azathioprine was added. Complete withdrawal of both prednisone and azathioprine was possible by using mycophenolate mofetil, an inosine monophosphate dehydrogenase inhibitor. Sustained remission has been maintained for more than 3 years with low-dose mycophenolate mofetil.

    Thirty-two cases of canine cutaneous histiocytosis were retrospectively evaluated. Median age at onset was 4 years. Lesions included nodules and plaques affecting the head/face, trunk and limbs, and erythema, swelling and depigmentation of the nasal planum/nares. Systemic involvement was not ruled out in all cases. All dogs had complete resolution of dermatological lesions after initial treatment (median 45 days). Initial treatment included prednisone +/- antibiotics (12 of 32 dogs), prednisone and tetracycline/niacinamide (four of 32), prednisone and azathioprine (three of 32), tetracycline/niacinamide +/- vitamin E/essential fatty acids (six of 32), antibiotics +/- antihistamines (three of 32), cyclosporine and ketoconazole (one of 32), topical therapy (two of 32), and no treatment (one of 32). Seventeen dogs received maintenance therapy which consisted of tetracycline/niacinamide +/- vitamin E/essential fatty acids (12 of 17), cyclosporine/ketoconazole (two to three times a week) (two of 17), azathioprine daily (one of 17), prednisone/azathioprine (two times a week) (one of 17), and prednisone daily (one of 17). Median follow up was 25 months. Nine dogs had a recurrence of cutaneous histiocytosis (median days to recurrence 130 days), with seven of nine having more than one recurrence. At study completion, six dogs were deceased (no lesions at the time of death) and 26 of 32 were alive with no lesions. Ten of 26 dogs were on maintenance treatment (eight tetracycline/niacinamide, one azathioprine, one vitamin E). Previous dermatological disease and season had no detectable influence on recurrence. Recurrence was significantly more likely in dogs with nasal planum/nares lesions than dogs without these lesions. Tetracycline/niacinamide was an effective treatment option for dogs in this study population.

    Full Text Available Abstract Introduction Hermansky-Pudlak syndrome (HPS is a rare autosomal recessive inherited disorder consisting of a triad of albinism, increased bleeding tendency secondary to platelet dysfunction, and systemic complications associated with ceroid depositions within the reticuloendothelial system. HPS has been associated with gastrointestinal (GI complications related to chronic granulomatous colitis with pathologic features suggestive of Crohn's disease. This colitis can be severe and has been reported to be poorly responsive to medical therapies including antibiotics, corticosteroids, sulfasalazine, mesalamine and azathioprine. Case presentation We report a patient with HPS which was complicated by inflammatory bowel disease with clinical and pathologic features of Crohn's disease, refractory to antibiotics, corticosteroids and azathioprine. A trial of infliximab was attempted and repeated infusions produced a complete response. Conclusion The occurrence of ileitis and perianal lesions and also the histopathological findings in our case suggest that HPS and Crohn's disease may truly be associated. Given this similarity and the failure of the standard medical therapy of corticosteroids and azathioprine, our patient received infliximab with marked clinical improvement.

    Decay accelerating factor (DAF) expression at the muscle endplate is an important defence against complement-mediated damage in myasthenia gravis. Previously we implicated the c.-198C>G DAF polymorphism with the development of treatment-resistant myasthenia-associated ophthalmoplegia by showing that the C>G DAF polymorphism prevented lipopolysaccharide-induced upregulation of lymphoblast DAF. We postulated that drugs used in myasthenia gravis may increase the susceptibility of extraocular muscles to complement-mediated damage and studied their effects on endogenous DAF using patient-derived lymphoblasts as well as mouse myotubes. We show that prednisone repressed C>G DAF expression in lymphoblasts and increased their susceptibility to cytotoxicity. Methotrexate, but not azathioprine or cyclosporine, increased DAF in C>G lymphoblasts. In mouse myotubes expressing wild-type Daf, prednisone also repressed Daf expression. Although cyclosporine, azathioprine, and methotrexate increased muscle Daf levels when used alone, upon co-treatment with prednisone only azathioprine maintained myotube Daf levels close to basal. Therefore, prednisone negatively influences DAF expression in C>G lymphoblasts and in myotubes expressing wild-type Daf. We speculate that myasthenic individuals at risk of developing the ophthalmoplegic complication, such as those with C>G DAF, may have inadequate endogenous levels of complement regulatory protein protection in their extraocular muscle in response to prednisone, increasing their susceptibility to complement-mediated damage.

    Full Text Available Pemphigus is a rare, chronic and life-threating autoimmune disease. The objective of this retrospective study was to evaluate the course and prognosis of pemphigus patients treated in our clinics. Medical records of 42 patients followed up regularly, and diagnosed at the Department of Dermatology, Faculty of Medicine, University of Dicle, from July 1994 to January 2004 were reviewed retrospectively. Of 42 patients with pemphigus, 38 had been treated with combination of methylprednisolone and azathioprine. Four patients had been treated with methylprednisolone alone. The initial doses ranged from 80 to 300 mg of methylprednisolone and 100-150 mg of azathioprine daily. No remission was obtained in 5 cases treated with combined therapy of methylprednisolone and azathioprine. Of 42 patients, 5 died during the study period. All of the patients who died were those patients with pemphigus vulgaris. In 4 patients, death occurred due to reasons related to the disease or treatment. Twenty nine patients were in complete remission with no therapy for duration varying between 4 months and 8 years.

    Aim To identify clinical and/or genetic predictors of response to several therapies in Crohn’s disease (CD) patients. Methods We included 242 patients with CD (133 females) aged (mean ± standard deviation) 39 ± 12 years and a disease duration of 12 ± 8 years. The single-nucleotide polymorphisms (SNPs) studied were ABCB1 C3435T and G2677T/A, IL23R G1142A, C2370A, and G9T, CASP9 C93T, Fas G670A and LgC844T, and ATG16L1 A898G. Genotyping was performed with real-time PCR with Taqman probes. Results Older patients responded better to 5-aminosalicylic acid (5-ASA) and to azathioprine (OR 1.07, p = 0.003 and OR 1.03, p = 0.01, respectively) while younger ones responded better to biologicals (OR 0.95, p = 0.06). Previous surgery negatively influenced response to 5-ASA compounds (OR 0.25, p = 0.05), but favoured response to azathioprine (OR 2.1, p = 0.04). In respect to genetic predictors, we observed that heterozygotes for ATGL16L1 SNP had a significantly higher chance of responding to corticosteroids (OR 2.51, p = 0.04), while homozygotes for Casp9 C93T SNP had a lower chance of responding both to corticosteroids and to azathioprine (OR 0.23, p = 0.03 and OR 0.08, p = 0.02,). TT carriers of ABCB1 C3435T SNP had a higher chance of responding to azathioprine (OR 2.38, p = 0.01), while carriers of ABCB1 G2677T/A SNP, as well as responding better to azathioprine (OR 1.89, p = 0.07), had a lower chance of responding to biologicals (OR 0.31, p = 0.07), which became significant after adjusting for gender (OR 0.75, p = 0.005). Conclusions In the present study, we were able to identify a number of clinical and genetic predictors of response to several therapies which may become of potential utility in clinical practice. These are preliminary results that need to be replicated in future pharmacogenomic studies. PMID:24918007

    Full Text Available Crohn’s disease (CD and Takayasu’s arteritis (TA are inflammatory granulomatous autoimmune disorders. Simultaneous occurrence of CD and TA in the same individual is rare. We report two cases treated with biologic agents. Case 1: A 16-year-old male presented with abdominal pain, nausea, vomiting. CT angiogram showed thickening of the terminal ileum, wall thickening and narrowing of multiple large and medium arteries including aorta and left common carotid. Colonoscopy with biopsy of the stenotic ileocecal valve confirmed CD. Resected carotid artery pathology was consistent with TA. Treatment was initially begun with prednisone, then methotrexate was started followed by infliximab. Due to side effects, methotrexate was switched to azathioprine. He remained asymptomatic. Case 2: A 38-year-old male with well-characterized Crohn’s ileocolitis for 15 years, who had been treated with prednisone, mesalamine, sulfasalazine, and azathioprine presented with chest, upper back and abdominal pain. CT angiogram showed vasculitis of large and medium arteries, with stenosis of the right renal artery, and wall thickening of the sigmoid colon. He was diagnosed with TA. He underwent treatment with infliximab and adalumimab on different occasions, which were later discontinued due to fever, bacteremia and complications from sepsis. He remained on prednisone and azathioprine. In these two patients with both CD and TA the diagnoses were confirmed by imaging and pathologic findings. Both patients developed vascular complications. Tumor necrosis factor inhibitor therapy was effective in one patient but discontinued in the other due to infection. Further research into the association of CD and TA may provide clues to their etiologies and guide effective interventions.

Conventional therapeutics for moderate-to-severe CD include 5-aminosalicylic acid, corticosteroids, purine analogs, azathioprine, and 6-mercaptopurine. Patients who fail to respond to conventional therapy are treated with tumor necrosis factor (TNF-α inhibitors such as infliximab and adalimumab, but their efficacy is limited due to primary nonresponse or loss of response. It is suggested that this requires switch to another TNF-α inhibitor, a combination therapy with TNF-α blockade plus azathioprine, or granulocyte and monocyte adsorptive apheresis, and that other therapeutic options having different mechanisms of action, such as blockade of inflammatory cytokines or adhesion molecules, are needed. Natalizumab and vedolizumab are neutralizing antibodies directed against integrin a4 and a4ß7, respectively. Ustekinumab is a neutralizing antibody directed against the receptors for interleukin-12 and interleukin-23. Here, we provide an overview of therapeutic treatments that are effective and currently available for CD patients, as well as some that likely will be available in the near future. We also discuss the advantages of managing patients with refractory CD using a combination of TNF-α inhibitors plus azathioprine or intensive monocyte adsorptive apheresis.

    2003-06-01

    Full Text Available Abstract Background Tuberculosis remains a serious world-wide health threat which requires the characterisation of novel drug targets for the development of future antimycobacterials. One of the key obstacles in the definition of new targets is the large variety of metabolic alterations that occur between cells in the active growth and chronic/dormant phases of tuberculosis. The ideal biochemical target should be active in both growth phases. Methionine adenosyltransferase, which catalyses the formation of S-adenosylmethionine from methionine and ATP, is involved in polyamine biosynthesis during active growth and is also required for the methylation and cyclopropylation of mycolipids necessary for survival in the chronic phase. Results The gene encoding methionine adenosyltransferase has been cloned from Mycobacterium tuberculosis and the model organism M. smegmatis. Both enzymes retained all amino acids known to be involved in catalysing the reaction. While the M. smegmatis enzyme could be functionally expressed, the M. tuberculosis homologue was insoluble and inactive under a large variety of expression conditions. For the M. smegmatis enzyme, the Vmax for S-adenosylmethionine formation was 1.30 μmol/min/mg protein and the Km for methionine and ATP was 288 μM and 76 μM respectively. In addition, the enzyme was competitively inhibited by 8-azaguanine and azathioprine with a Ki of 4.7 mM and 3.7 mM respectively. Azathioprine inhibited the in vitro growth of M. smegmatis with a minimal inhibitory concentration (MIC of 500 μM, while the MIC for 8-azaguanine was >1.0 mM. Conclusion The methionine adenosyltransferase from both organisms had a primary structure very similar those previously characterised in other prokaryotic and eukaryotic organisms. The kinetic properties of the M. smegmatis enzyme were also similar to known prokaryotic methionine adenosyltransferases. Inhibition of the enzyme by 8-azaguanine and azathioprine provides a starting

    The first renal transplant was done on July 22, 1968 and until December, 2010 a total of 865 procedures have been performed. Immunosuppressive protocols have changing with time: from 1968 to 1984 azathioprine + prednisone plus total radiation in some cases; from 1985 to 1998 cyclosporine + azathioprine + prednisone; in 1998 tacrolimus is used for first time; Mofetil micofenolate was available at 2005 and practically has displaced to azathioprine. As far as possible we use some induction therapy. Primary ESRD etiologies were: unknown (74.9%), glomerulonephritis (9.7%) and diabetic nephropathy (4.2%). Recipient's mean age was 29.9 +/- 11.6 years (12-70) and 35 +/- 9.8 years (18-62) in donors. Analysis group for graft and patient survival included 292 transplants (censured for death with functional graft) with a follow-up of 103 months (CI 95%: 99-108). Survival at 1, 5 and 10 years were: 95, 85 and 60% for graft as well as 100, 94 and 90% for patient. In year 2000 we started to perform renal biopsies at transplant (time zero biopsies), those results have been published and at present are a worldwide reference. In September, 2005 laparoscopic donor nephrectomy is initiated, 180 procedures have been done with excellent results. In year 2006, training in renal transplant acquires the endorsement as a Medicine Posgrade recognized by the UNAM School of Medicine. We have participated in 9 national clinical trials and 6 international multicentric ones. Our renal transplant program offers a good choice for patients with low resources with similar results reported in the literature using current immunosuppressive schemes and surgical procedures. Institutional authorities and humanitarian associations support in addition to participation on investigation studies have been of vital importance.

    2007-06-24

    There are fewer significant changes in the medical therapy of ulcerative colitis (UC) compared to Crohn's disease. The most important factors that determine therapy are disease extent and severity. 5-aminosalicylates (5-ASA) constitute the treatment of choice in mild-to-moderate UC. The efficacy of new compounds (e.g. mesalazine) is only mildly improved compared to sulphasalazine; however, their use has become more frequent due to a more favorable side effects profile. Topical medication is more effective in proctitis and distal colitis, and the combination of topical and orally-administered drugs is superior to oral therapy alone also in extensive disease. Thus, this latter regimen should be considered for cases where the escalation of treatment is required. Systemic steroids still represent the first line therapy in acute, severe UC, while in patients who do not respond to steroids, cyclosporine and infliximab should be considered as a second line therapy and as alternatives for colectomy. Maintenance treatment is indicated in all UC cases. 5-ASA compounds are suggested as first line maintenance therapy with the optimal dose still being under investigation. Topical compounds are effective also for maintenance in distal colitis or proctitis, if accepted by the patients. Immunosuppressives, especially azathioprine, should be considered in chronically active, steroid dependent or resistant patients. According to recent publications, azathioprine is almost equally effective in UC and CD. The question of chemoprevention is important during maintenance. There are increasing data supporting the notion that aminosalicylates may lower the risk for UC-associated colorectal cancer. The most important changes in the management of UC are the more frequent use of topical aminosalicylates and azathioprine, the availability of infliximab in severe UC, and increasing use of aminosalicylates for chemoprevention of colorectal carcinoma. Furthermore, adequate attention is needed to

    Therapy for orbital pseudotumor, also called idiopathic orbital inflammation, is nonspecific and mainly based on the use of corticosteroids. Two patients with steroid-dependent idiopathic orbital inflammation, one with myositis and the other with dacryoadenitis, and intolerant of standard steroid sparing agents (methotrexate or azathioprine), were treated with infliximab, a monoclonal antitumor necrosis factor alpha antibody. In both patients, orbital manifestations disappeared following treatment. After follow-up for at least 20 months, the 2 patients still receiving infliximab remained event free. Infliximab enabled steroid tapering to less than 5 mg per day, suggesting that infliximab could constitute an alternative to conventional steroid sparing agents.

    Abstract Background: Thalidomide has been successful use in patients with refractory Crohn disease (CD) in recent years. Methods: We collected the data of a postoperative CD patient who was prescribed thalidomide to induce remission and reviewed the relevant literatures. Results: A 51-year-old female was diagnosed as CD after an urgent terminal intestinal resection and presented endoscopic recurrence despite the prophylactic treatment with azathioprine (AZA). Fortunately, she achieved mucosal healing (MH) at a low dose of thalidomide for 15 months. Conclusion: Thalidomide is effective to induce MH in the postoperative CD endoscopic recurrence.

    Multiphasic disseminated encephalomyelitis (MDEM) followed by optic neuritis (ON) has been described as a new entity in recent years. Gluten encephalopathy has also been recognized as a neurological manifestation of celiac disease. Accurate diagnosis of both is important due to the therapeutic implications. We report a girl presenting with recurrent encephalopathic polyfocal demyelinating episodes followed by optic neuritis, and a clinical history suggestive of gluten sensitivity. She had persistently high ESR, neutrophilia, and tested positive for anti-MOG (myelin oligodendrocyte glycoprotein) antibody. She responded well to methylprednisolone in each relapse, and achieved remission for a year after azathioprine was added.

    Acute pancreatitis or a pancreatic mass is a very rare initial presentation of Wegener's granu-lomatosis. A 62-year-old woman presented with tumor-like pancreatitis and otitis media Abdominal ultrasound and magnetic resonance suggested the presence of pancreatic tumor. Ultrasound-guided fine needle aspiration was negative. Distal pancreatic resection and splenectomy were performed and histopathology proved Wegener's vasculitis of the pancreas and spleen. Azathioprine and steroids were subsequently started and six months later the patient was asymptomatic. Involvement of the pancreas could be considered as a presenting symptom of Wegener's vasculitis.

    Primary Antiphospholipid Antibody Syndrome (PAPS) and Autoimmune haemolytic anemia (AIHA) is a very rare combination. Antiphospholipid Antibody Syndrome (APS) with underlying SLE, however, has a well documented association with Coomb's positive Auoimmune Haemolytic Anaemia. We describe a young girl with PAPS presenting with deep venous thrombosis, livedo reticularis and features of AIHA. The patient was refractory to treatment for 5 years however, her condition improved dramatically with anticoagulants, corticosteroid therapy and the addition of hydroxychloroquine and azathioprin. We have also discussed hydroxychloroquine therapy in PAPS which is not yet fully established and the probability of this patient developing other autoimmune disorders in future.

    Systemic lupus erythematosus-related hepatitis, known as lupus hepatitis, is a rare manifestation of systemic lupus erythematosus, and is usually subclinical with mild abnormalities of serum liver enzymes. While cases with clinically significant and refractory lupus hepatitis are uncommon, treatment options for lupus hepatitis are to be established. Here, we report the case of a 45-year-old man with progressive lupus hepatitis accompanied by autoimmune haemolytic anaemia. Lupus hepatitis of this patient was refractory to tacrolimus, azathioprine and cyclophosphamide, but was successfully treated by mycophenolate mofetil. Mycophenolate mofetil might be an effective therapeutic option for refractory lupus hepatitis.

    Full Text Available The common therapeutic goal for all subepidermal bullous diseases is to prevent inflammation and production of pathogenic autoantibodies and/or to facilitate the elimination of these antibodies. Diseases included in this group are the pemphigoids, linear IgA dermatosis, epidermolysis bullosa acquisita, dermatitis herpetiformis and bullous systemic erythematosus. Corticosteroids are the most commonly used systemic medication. Other alternatives include dapsone, various antibiotics and nicotinamide, azathioprine, cyclophosphamide, methotrexate, cycloporine, mycophenolate mofetil, IV immunoglobulins and plasmapheresis.

    Gallbladder disease is no more common in patients with systemic lupus erythematosus (SLE) than in the general population. We describe a 17-year-old patient with SLE, who developed nephritis that was well controlled with medications. Initial treatment consisted of azathioprine, aspirin and prednisone with stable control of her symptoms. Two years later she developed a right quadrant abdominal pain,and an abdominal ultrasound revealed microlithiasic cholecystitis. Open cholecystectomy was performed and the histopathological findings revealed vasculitis with thrombotic microangiopathy in the gallbladder. This case presentation illustrates that calculous or acalculous cholecystitis should be considered as a manifestation of active SLE and APS.

    Chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids (CLIPPERS) is a recently described central nervous system inflammatory condition. In this case report we describe a patient initially with features consistent with this syndrome, who represented with seizures (not previously reported in this syndrome) and corresponding prominent cortical involvement on imaging (also not previously noted). Owing to diagnostic uncertainty, cerebral biopsy was performed revealing histology consistent with CLIPPERS, excluding other differentials. Following a further brainstem relapse, this patient was treated with high-dose steroids, subsequently switched to a tapering oral regime and now, azathioprine, a steroid-sparing agent. She remains well on this.

  5. The Use of Budesonide in the Treatment of Autoimmune Hepatitis in Canada

    Directory of Open Access Journals (Sweden)

    2008-01-01

    Full Text Available BACKGROUND: Autoimmune hepatitis (AIH is a chronic inflammatory disease that is successfully treated with prednisone and/or azathioprine immunosuppressive therapy in 70% to 80% of patients. The remaining patients are intolerant or refractory to these standard medications. Budesonide, a synthetic glucocorticoid, undergoes a high degree of first-pass metabolism, reducing its systemic bioavailability, and has a 15-fold greater affinity for the glucocorticoid receptor than prednisolone. Budesonide may be a potentially useful systemic steroid-sparing immunosuppressive agent in the treatment of AIH.

    Magnetic resonance scans of 74 patients with multiple sclerosis participating in a controlled trial were compared 6 months before and at the end of a 24-32 months-treatment period with either Cyclosporin A (n=31) or Azathioprine (n=43). Both qualitative rating and computation of lesion volume showed deterioration in more than 40% of the patients, while by clinical criteria only 10-30% were worse. No significant difference was noted when the two treatment groups were compared. If careful repositioning and standardized image parameters are used, MRI is an indispensable tool for the objective determination of disease progression in MS although it cannot replace clinical examination.

  7. Pancolitis with Ischemic Injury as a Complication of Immunosuppressive Treatment in a Patient with Autoimmune Hepatitis: A Case Report

    2012-01-01

    Full Text Available Ischemic colitis is a serious drug-induced adverse event. There are only few cases of immunosuppression-associated ischemic colitis described in the literature, but none with a pancolitis-like manifestation. We report the case of a 72-year-old female patient who developed a pancolitis with ischemic injury on immunosuppressive treatment with steroids and azathioprine for autoimmune hepatitis. The patient presented with massive rectal bleeding. Colonoscopy confirmed the diagnosis of pancolitis. The results of histological examination indicated drug-induced ischemic colitis involving the entire colon. This is the first case of ischemic pancolitis mimicking an inflammatory bowel disease (IBD in a patient with immunosuppressive therapy.

    A 64-year-old man with no past medical history presented with abnormally elevated liver enzymes 1 year after developing a diffuse rash thought to be related to eating large quantities of raw cashew nuts. Liver biopsy was performed, which revealed features concerning for drug- or toxin-induced autoimmune hepatitis. The patient began treatment with azathioprine and prednisone, and liver enzymes normalized. We describe a unique case of a toxin-induced autoimmune hepatitis precipitated not by a drug or dietary supplement but by a food product.

    2013-01-01

    Full Text Available Drug rash with eosinophilia and systemic symptoms (DRESS syndrome is an adverse reaction commonly occurring with antiepileptic agents. It was earlier referred to by various names such as dilantin hypersensitivity syndrome and anticonvulsant hypersensitivity syndrome. It is characterized by the triad of fever, skin eruption, and systemic involvement. DRESS syndrome has also been reported with a number of other drugs including allopurinol, minocycline, terbinafine, sulfonamides, azathioprine, dapsone, and antiretroviral agents such as abacavir and nevirapine. We describe a rare case of nevirapine-induced hypersensitivity syndrome that was successfully treated with oral steroids.

    2015-09-28

    We report a case of acute severe hepatitis resulting from masitinib in a young amyotrophic lateral sclerosis patient. Hepatotoxicity induced by masitinib, a tyrosine kinase inhibitor, is usually transient with mild elevation of transaminases, although acute hepatitis has been not reported to date. The hepatitis was resolved after masitinib was discontinued and a combination of prednisone and azathioprine was started. The transaminases returned to baseline normal values five months later. This is the first case in the hepatitis literature associated with masitinib. The autoimmune role of this drug-induced liver injury is discussed. Physicians should be aware of this potential complication.

    2008-05-18

    The most important factors that determine treatment strategy in ulcerative colitis (UC) are disease extent and severity. Orally-topically administered 5-aminosalicylates (5-ASA) remain the treatment of choice in mild-to-moderate UC. In contrast, the treatment of refractory (to steroids, azathioprine or 5-ASA) and fulminant cases is still demanding. New evidence supports a role for infliximab induction and/or maintenance therapy in these subgroup of patients leading to increased remission and decreased colectomy rates. The aim of this paper is to review the rationale for the use of TNF-alpha inhibitors in the treatment of UC.

    Pemphigus vulgaris (PV) is an autoimmune bullous and erosive mucocutaneous disease. Rarely, it occurs in patients with other autoimmune disease. The relation between PV and neurological disorders is unclear and needs to be more studied. Here, we report a case of amyotrophic lateral sclerosis (ALS), followed by dermatologic involvement. Histopathological evidence and direct immunofluorescence are consistent with PV. Systemic corticosteroid and azathioprine were effective in the treatment of mucocutaneous lesions. PV seems to be accidentally associated with ALS. Expression of major histocompatibility complex Class II in autoimmune disease and production of autoantibodies have been proposed to describe the association of PV with ALS. PMID:28163728

  13. Nonstandard drugs and feasible new interventions for autoimmune hepatitis: part I.

    Science.gov (United States)

    Czaja, Albert J

    2012-10-01

    Nonstandard drugs that target critical pathogenic pathways or immune regulatory mechanisms constitute the next generation of treatments for autoimmune hepatitis. Mycophenolate mofetil impairs the proliferation of lymphocytes, decreases autoantibody production, and induces apoptosis of activated immunocytes. Patients treated for azathioprine intolerance improve more frequently than patients treated for refractory liver disease (54% versus 10%), and mycophenolate mofetil is emerging as a rescue therapy for this population. Complete corticosteroid withdrawal is possible in 40% of patients treated with mycophenolate mofetil, and the frequency of side effects ranges from 3-34%. Budesonide in combination with azathioprine has normalized liver tests more frequently (47% versus 18%) and with fewer side effects (28% versus 53%) than standard therapy after 6 months. Budesonide is emerging as a frontline treatment in non-cirrhotic patients with uncomplicated disease or contraindications to conventional corticosteroids. Cyclosporine and tacrolimus are effective salvage agents for steroid-refractory disease, but side effects have been common and occasionally serious. The 6- thioguanine nucleotides and rapamycin are feasible treatments for autoimmune hepatitis, but 6-thioguanine has major obstacles to overcome, especially the risk of liver toxicity or nodular regenerative hyperplasia. The nonstandard drug therapies emerging for autoimmune hepatitis reflect the need to supplement or supplant current treatment regimens. None has been licensed for use in autoimmune hepatitis, and their applications have been based on results from small singlecenter experiences.

    Full Text Available A forty-year-old man underwent an allogeneic BMT from his HLA identical sister. GvHD prophylaxis was done with cyclosporine (CyA, methotrexate and prednisone (PDN. On day +90 extensive GvHD was noted and higher doses of immunosuppressive drugs alternating CyA with PDN were initiated. Patient's follow-up was complicated by intermittent episodes of leukopenia and monthly episodes of sinusitis or pneumonia. One year after BMT, the patient developed hoarseness and nasal voice. No etiologic agent could be identified on a biopsy sample of the vocal chord. Upon tapering the doses of immunosuppressive drugs, the patient had worsening of chronic GvHD and was reintroduced on high doses of cyclosporine alternating with prednisone on day +550. Three months later, GvHD remained out of control and the patient was started on azathioprine. On day +700, hoarseness and nasal voice recurred. Another biopsy of the left vocal chord failed to demonstrate infection. Episodes of sinusitis became more frequent and azathioprine was withheld 3 months after it was started. One month later, the patient had bloody nasal discharge and surgical drainage of maxillary sinuses was performed. Histopathology showed hyphae and cultures grew Scedosporium apiospermum. ltraconazole 800 mg/day was initiated. The patient developed progressive respiratory failure and died 15 days later.

    Full Text Available Literature regarding acute human toxicity of thiopurines is limited to a handful of case reports. Our objectives were to describe all cases of overdose with thiopurines reported to the Swiss Toxicological Information Centre between 1995-2013. A retrospective analysis was performed to determine circumstances, magnitude, management and outcome of overdose with these substances. A total of 40 cases (14 paediatric were reported (azathioprine, n = 35; 6-mercaptopurine, n = 5. Of these, 25 were with suicidal intent, 12 were accidental and 3 were iatrogenic errors. The magnitude of overdose ranged from 1.5 to 43 (median 8 times the usual dose in adults. Twelve cases (30% had attributable symptoms. The majority of these were minor and included gastrointestinal complaints and liver function test and blood count abnormalities. Symptoms were experienced by patients who took at least 1.5-times their usual daily thiopurine dose. Overdoses over two or more consecutive days, even if of modest size, were less well tolerated. One case of azathioprine and allopurinol co-ingestion over consecutive days led to agranulocytosis. Decontamination measures were undertaken in 11 cases (10 activated charcoal, 1 gastric lavage and these developed fewer symptoms than untreated patients. This study shows that acute overdoses with thiopurines have a favourable outcome in the majority of cases and provides preliminary evidence that gastrointestinal decontamination with activated charcoal may reduce symptom development after overdose of these substances if patients present to medical services soon after ingestion.

    Full Text Available Natasha Jordan,1 David D’Cruz2 1Department of Rheumatology, Cambridge University Hospitals NHS Foundation Trust, Cambridge, 2Louise Coote Lupus Unit, Guy’s and St Thomas’ Hospital NHS Foundation Trust, London, UK Abstract: Systemic lupus erythematosus (SLE is a complex autoimmune disease with variable clinical manifestations. While the clearest guidelines for the treatment of SLE exist in the context of lupus nephritis, patients with other lupus manifestations such as neuropsychiatric, hematologic, musculoskeletal, and severe cutaneous lupus frequently require immunosuppression and/or biologic therapy. Conventional immunosuppressive agents such as mycophenolate mofetil, azathioprine, and cyclophosphamide are widely used in the management of SLE with current more rationalized treatment regimens optimizing the use of these agents while minimizing potential toxicity. The advent of biologic therapies has advanced the treatment of SLE particularly in patients with refractory disease. The CD20 monoclonal antibody rituximab and the anti-BLyS agent belimumab are now widely in use in clinical practice. Several other biologic agents are in ongoing clinical trials. While immunosuppressive and biologic agents are the foundation of inflammatory disease control in SLE, the importance of managing comorbidities such as cardiovascular risk factors, bone health, and minimizing susceptibility to infection should not be neglected.

    Full Text Available Antiphospholipid syndrome (APS is a systemic disease that causes venous and arterial thrombosis in virtually any organ. Sometimes it is complicated into pulmonary infarction and cavitation, pulmonary hypertension, and catastrophic course with high morbidity and mortality. The present case is a 35-year-old woman with one episode of postpartum deep veins thrombosis (DVT 12 years earlier and the second one after the second labor two years later. In spite of usual therapy for each episode of DVT, the condition had progressed into severe pulmonary hypertension. The diagnosis of primary APL syndrome was confirmed four years ago. She had been on warfarin, low dose of steroid, and azathioprine since the diagnosis of APL syndrome. After one year treatment with steroid and azathiprine the patient showed progressive well being; however, because of hyperglycemia the steroid tapered and discontinued. She had several attacks of paroxismal atrial tachycardia in the last year. On the last time, she presented with severe dyspnea, hemoptesis, and lower limbs edema. Chest radiography and Lung CT scan demonsterated the presence of lung cavitations. Because of high suspicious for fungal pulmonary infection, azathioprine was also discontinued. However, constellation renal failure, hemodynamic instability, and confusion caused the patient to succumb to death. The definite diagnosis of lung cavitations was not obtained

    Kronbichler, Andreas; Jayne, David R W

    2015-07-01

    Rituximab has enriched our armamentarium in the treatment of anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis. Two randomised controlled trials have shown that rituximab is non-inferior compared with cyclophosphamide followed by azathioprine for the induction of remission. The newly diagnosed patients in the Rituximab in ANCA-Associated Vasculitis (RAVE) and Rituximab Versus Cyclophosphamide in ANCA-Associated Vasculitis (RITUXVAS) trials had a numerically higher response rate in the cyclophosphamide/azathioprine arm, and the number of such patients treated with rituximab numbered cases and late-onset neutropaenia are complications not seen with cyclophosphamide. Over the longer term it is unclear what relapse prevention strategy should be employed after rituximab, and there was a trend to a higher relapse risk after rituximab in the RITUXVAS trial at 2 years. Further health economic studies are required to understand all the costs associated with rituximab. In the context of concomitant underlying infectious complications, in terms of fertility concerns, especially in young patients, and when malignancy is underlying we would recommend the use of rituximab as first-line therapy.

    Aortitis is a nonspecific term that describes an inflammation of the aortic wall caused by inflammatory, infectious, paraneoplastic and idiopathic diseases. The symptoms are variable and nonspecific; therefore a high level of clinical suspicion is required to diagnose it. It is often an incidental finding while looking for other diagnoses and it is confirmed mainly through imaging studies. We report three cases of aortitis: A 29-year-old woman presenting with alopecia, oral and nasal ulcers and positive antinuclear antibodies. A CAT scan showed a segmental thickening of thoracic aorta, with dilated and stenotic areas. She was successfully treated with steroids, hydroxychloroquine, cyclophosphamide and azathioprine. A 41-year-old male presenting with dorsal pain and cough. The CAT scan showed an extra-intimal thickening of the descending aorta and stenosis of the celiac artery. The final diagnosis was a polyangiitis and was treated with steroids, cyclophosphamide and azathioprine. A 28-year-old woman presenting with pain in the left upper abdomen. Imaging studies showed a thickening of the aortic arch and subclavian artery. The final diagnosis was sarcoidosis and the patient was treated with prednisone.

    Systemic lupus erythematosus (SLE) is an autoimmune disease which may involve gastrointestinal system (GIS). The aim of this study was to present GIS manifestations of pediatric SLE patients. The medical files of 69 children with SLE followed between January 2011 and January 2016 were reviewed. All fulfilled the Systemic Lupus International Collaborating Clinics criteria. All patients (≤18 years of age) with GIS manifestations were included. GIS manifestations were observed in 19 (27.5%) out of 69 SLE patients and present at the time of SLE diagnosis in 13 (68.4%). The GIS manifestations due to SLE were autoimmune hepatitis (AIH) (n = 8) and lupus enteritis (n = 1). Manifestations associated with SLE were hepatomegaly and hypertransaminasemia due to macrophage activation syndrome (MAS) (n = 3) and hepatic steatosis (n = 1). GIS manifestations as a result of the adverse events of drugs were as follows: toxic hepatitis (n = 3; associated with methotrexate and nonsteroidal anti-inflammatory drugs in one, methotrexate in another, and azathioprine in another patient), azathioprine-induced cholestatic hepatitis (n = 1), and gastritis associated with corticosteroid (n = 1). In one patient, acute appendicitis occurred as a coincidence. In this study, one of every five pediatric SLE patients had GIS-related manifestations. GIS involvement may occur as an initial manifestation of the disease.

    Full Text Available Refractory coeliac disease (RCD is a rare complication of coeliac disease (CD and involves malabsorption and villous atrophy despite adherence to a strict gluten-free diet (GFD for at least 12 months in the absence of another cause. RCD is classified based on the T-cells in the intra-epithelial lymphocyte (IEL morphology into type 1 with normal IEL and type 2 with aberrant IEL (clonal by PCR (polymerase chain reaction for T cell receptors (TCR at the β/γ loci. RCD type 1 is managed with strict nutritional and pharmacological management. RCD type 2 can be complicated by ulcerative jejunitis or enteropathy associated lymphoma (EATL, the latter having a five-year mortality of 50%. Management options for RCD type 2 and response to treatment differs across centres and there have been debates over the best treatment option. Treatment options that have been used include azathioprine and steroids, methotrexate, cyclosporine, campath (an anti CD-52 monoclonal antibody, and cladribine or fluadribine with or without autologous stem cell transplantation. We present a tertiary centre’s experience in the treatment of RCD type 2 where treatment with prednisolone and azathioprine was used, and our results show good response with histological recovery in 56.6% of treated individuals.

    Non-classical manifestations of autoimmune hepatitis can delay diagnosis and treatment. Our aims were to describe the clinical phenotypes that can confound the diagnosis, detail scoring systems that can ensure their recognition, and outline advances in treatment that can improve their outcome. Prime source and review articles in English were selected through Medline from 1970-2008 and assimilated into personal libraries spanning 32 years. Acute severe or asymptomatic presentations and atypical histological findings,including centrilobular zone 3 necrosis and concurrent bile duct changes, are compatible with the diagnosis.Cholangiographic abnormalities may be present in children and adults with the disease, and autoimmune hepatitis must be considered in patients without autoantibodies or with antimitochondrial antibodies and no other cholestatic features. Asymptomatic patients frequently become symptomatic; mild disease can progress; and there are no confident indices that justify withholding treatment. Two diagnostic scoring systems with complementary virtues have been developed to evaluate patients with confusing features. Normal liver tests and tissue constitute the optimal end point of treatment, and the first relapse is an indication for longterm azathioprine therapy. Cyclosporine, tacrolimus and mycophenolate mofetil are promising salvage therapies, and budesonide with azathioprine may be a superior frontline treatment. We conclude that the non-classical phenotypes of autoimmune hepatitis can be recognized promptly, diagnosed accurately, and treated effectively.

    We report the case of a 21-year-old man who was noted to have pneumomediast inum dur ing an admission for an acute flare of ulcerative colitis. At that time, he was on maintenance treatment with azathioprine at a dose of 1.25 mg/kg per day, and had not received supplementary steroids for 9 mo. He had never received anti-tumor necrosis factor (TNF)α therapy. Shortly after apparently effective treatment with intravenous steroids and an increased dose of azathioprine, he developed worsening colitic and new respiratory symptoms, and was diagnosed with Pneumocystis jiroveci ( carinii) pneumonia (PCP). Pneumomediastinum is rare in immunocompetent hosts, but is a recognized complication of PCP in human immunodeficiency virus (HIV) patients, although our patient 's HIV test was negative. Treatment of PCP with co-trimoxazole resulted in resolution of both respiratory and gastrointestinal symptoms, without the need to increase the steroid dose. There is increasing vigilance for opportunistic infections in patients with inflammatory bowel disease following the advent of anti-TNFα therapy. This case emphasizes the importance of considering the possibility of such infections in all patients with inflammatory bowel disease, irrespective of the immunosuppressants they receive, and highlights the potential of steroid-responsive opportunistic infections to mimic worsening colitic symptoms in patients with ulcerative colitis.

    Takayasu's arteritis (TA) and Giant cell arteritis (GCA) comprise the large vessel vasculitides (LVV). Patients with LVV are treated with disease-modifying anti-rheumatic drugs (DMARDs), both conventional (cDMARDs) and biologic (bDMARDs). We undertook a scoping review to assess the effectiveness of cDMARDs in TA and GCA. We could identify 11 studies in TA and 18 studies in GCA. There were only 3 randomized controlled trials on methotrexate, one on hydroxychloroquine and two on cyclosporine in GCA, the others being case series (including all studies on TA). Most of these studies had small patient numbers (median 15 in TA and 27 in GCA). Outcome measures reported in different studies were heterogenous. Overall, methotrexate, leflunomide, azathioprine, mycophenolate mofetil and cyclophosphamide were effective in TA (low quality of evidence). Methotrexate (high quality of evidence), hydroxychloroquine and cyclosporine (moderate quality of evidence) appeared to be ineffective in GCA. Azathioprine (moderate quality of evidence), leflunomide, mycophenolate mofetil, cyclophosphamide and dapsone (low quality of evidence) were effective in GCA. There exists a paucity of high quality evidence to guide use of cDMARDs in TA and GCA. There is an unmet need to conduct large multi-centric randomized placebo-controlled trials to accurately assess the utility on cDMARDs in LVV.

    From 1969 to 1987, 35 pregnancies occurred in 31 women with renal transplant. Four of them were still pregnant when this study was concluded. There was one ectopic pregnancy. All patients received azathioprine and prednisone. In the majority of patients the glomerular filtration rate increased in a way similar to normal pregnant women. In five cases there was a progressive loss in renal function. In four of them this was attributed to preexistent renal damage. No toxemia occurred. Anemia developed during 11 pregnancies and blood transfusion was required for five women. Four patients had urinary tract infection which was easily controlled with antibiotics. One patient had severe arterial hypertension, secondary to chronic rejection. One patient developed jaundice reverted with reduction in azathioprine doses. One woman died of septicemia secondary to fetal death, during the 6th month of pregnancy. Twenty children were born with no abnormalities, although many of them were underweighted. Two thirds of pregnancies were delivered by cesarean section. No harm to the pelvic allograft occurred in vaginal deliveries. There have been 4 abortions (2 of them were induced with no medical indication). Four pregnancies (26 to 39 gestational weeks) ended in stillborn babies: the mothers had impaired renal function associated with hypertension and proteinuria. One newborn died of pulmonary infection two days after delivery. Another was born with microcephaly and polydactilia and survived 6 years. No breast feeding was allowed.

    Autoimmune hepatitis is an unresolving, hepatocellular inflammation of unknown cause that is characterized by the presence of periportal hepatitis on histologic examination, tissue autoantibodies in serum, and hypergammaglobulinemia. By international consensus, the designation autoimmune hepatitis has replaced alternative terms for the condition. Three types of autoimmune hepatitis have been proposed based on immunoserologic findings. Type 1 autoimmune hepatitis is characterized by the presence of antinuclear antibodies (ANA) or smooth muscle antibodies (SMA) (or both) in serum. Seventy percent of patients with type 1 of autoimmune hepatitis are women. This type is the most common form and accounts for at least 80% of cases. Type 2 is characterized by the presence of antibodies to liver-kidney microsome type 1 (anti-LKM1) in serum. Patients with this type of autoimmune hepatitis are predominantly children. Type 3 autoimmune hepatitis is characterized by the presence of antibodies to soluble liver antigen (anti-SLA) in serum. There are no individual features that are pathognomonic of autoimmune hepatitis, and its diagnosis requires the confident exclusion of other conditions. The large majority of patients show satisfactory response to corticosteroid (usually prednisone or prednisolone) therapy. For the past 30 years it has been customary to add azathioprine as a "steroid sparing" agent to allow lower doses of steroids to be used and remission, once achieved, can be sustained in many patients with azathioprine alone after steroid withdrawal. Patients with autoimmune hepatitis who have decompensated during or after corticosteroid therapy are candidates for liver transplantation.

    Full Text Available Objective. To describe the clinical characteristics and radiological findings in two patients with subacute encephalitis associated with elevated serum voltage-gated potassium channel antibody (VGKCAb and antithyroperoxidase (TPO antibody. Case Reports. Case 1: 63-year-old woman was admitted for altered mental status and possible seizure activity. MRI brain showed hyperintensity in the bilateral hippocampal areas. She was positive for VGKCAb and anti-TPO antibodies. She was treated with steroids, IVIG, plasma exchange and azathioprine. After 8 months, she had marked improvement in her memory and seizures. Case 2: 61-year-old woman was admitted for video EEG monitoring of unclassified seizure and cognitive function decline. MRI of the brain showed mild hyperintensity in bilateral hippocampal areas and significant atrophy in the frontotemporal lesion. Anti-TPO antibody and VGKCAb were positive. She was treated with steroids, plasma exchange and azathioprine. After 9 months, she had marked improvement in her memory and seizures. Conclusion. Autoimmune subacute encephalitis appears to be an underdiagnosed entity. It is important to screen patients with subacute encephalitis for anti-TPO antibody and VGKCAb, particularly in the presence of seizures. Immunosuppressive therapy appears to be effective in treating this entity.

    Full Text Available Autoimmune hepatitis is (AIH is a chronic hepatitis that occurs in children and adults of all ages. It is characterized by immunologic and autoimmune features, including circulating auto antibodies and high serum globulin concentrations. It was first described in the 1950s by term of chronic active hepatitis. It has 2 types with different auto antibodies. Diagnosis is based upon serologic and histologic findings and exclusion of other forms of chronic liver disease.   A scoring system should be used in assessment based upon: 1 Auto anti bodie titer 2 Serum IgG level  3 Liver histology 4 Absence of viral and other causes of hepatitis. Clear indications for treatment: 1   rise of aminotrasferases 2   clinical symptoms of liver disease 3   histological features in liver biopsy 4   Children with AIH initial treatment involve glucocorticoid with or without azathioprine. For patients with fulminant hepatitis liver transplantation, should be kept in mind.   Remission is defined by: 1   Resolution of symptoms 2   Normalization of serum trasaminases 3   Normalization of serum bilirubin and gamma globuline levels. 4   Improvement in liver histology 5   Treatment is continued for at least 2-5 years, glucocorticoids are with drawn first, by tapering over six weeks. Azathioprine will be with drawn.  

  11. Myasthenia gravis: an update for the clinician.

    2014-03-01

    This paper provides a thorough overview of the current advances in diagnosis and therapy of myasthenia gravis (MG). Nowadays the term 'myasthenia gravis' includes heterogeneous autoimmune diseases, with a postsynaptic defect of neuromuscular transmission as the common feature. Myasthenia gravis should be classified according to the antibody specificity [acetylcholine, muscle-specific receptor tyrosine kinase (MuSK), low-density lipoprotein receptor-related protein 4 (LRP4), seronegative], thymus histology (thymitis, thymoma, atrophy), age at onset (in children; aged less than or more than 50 years) and type of course (ocular or generalized). With optimal treatment, the prognosis is good in terms of daily functions, quality of life and survival. Symptomatic treatment with acetylcholine esterase inhibition is usually combined with immunosuppression. Azathioprine still remains the first choice for long-term immunosuppressive therapy. Alternative immunosuppressive options to azathioprine include cyclosporin, cyclophosphamide, methotrexate, mycophenolate mofetil and tacrolimus. Rituximab is a promising new drug for severe generalized MG. Emerging therapy options include belimumab, eculizumab and the granulocyte- macrophage colony-stimulating factor. One pilot study on etanercept has given disappointing results. For decades, thymectomy has been performed in younger adults to improve non-paraneoplastic MG. However, controlled prospective studies on the suspected benefit of this surgical procedure are still lacking. In acute exacerbations, including myasthenic crisis, intravenous immunoglobulin, plasmapheresis and immunoadsorption are similarly effective.

    Full Text Available A 25-year-old patient was referred due to subclavian stenosis, identified on echocardiography. She presented with exertional dizziness and dyspnoea. Questioning revealed bilateral arm claudication. Examination demonstrated an absent right ulnar pulse and asymmetrical brachial blood pressure. Bruits were evident over both common carotid arteries. Doppler ultrasound and MRI angiograms revealed occlusion or stenosis in multiple large arteries. Takayasu arteritis (TA was diagnosed and induction therapy commenced: 1 mg/kg oral prednisolone and 500 mg/m2 intravenous cyclophosphamide (CYC. Attempts to reduce prednisolone below 15 mg/d proved impossible due to recurring disease activity. Adjuvant azathioprine 100 mg/d was subsequently added. Several weeks later, the patient was admitted with a left homonymous hemianopia. The culprit lesion in the right carotid artery was surgically managed and the patient discharged on azathioprine 150 mg/d and prednisolone 30 mg/d. Despite this, deteriorating exertional dyspnoea and angina pectoris were reported. Reimaging confirmed new stenosis in the right pulmonary artery. Surgical treatment proved infeasible. Given evidence of refractory disease activity on maximal standard therapy, we initiated rituximab, based on recently reported B-cell activity in TA.

    Cyclophosphamide (CYC) has been the landmark in the treatment of lupus nephritis. However, long-term treatment with CYC is associated with significant side effects. We aimed to evaluate the efficacy of short-term intravenous (IV) CYC treatment as a remission induction treatment followed by azathioprine (AZA) or mycophenolate mofetil (MMF) as a maintenance treatment. Twenty patients (18 girls) with biopsy-proven class III (5) and IV (15) lupus nephritis were included in to the study. Detailed clinical and laboratory data and patient outcomes were evaluated. All patients received three methylprednisolone (MP) IV pulses, followed by oral prednisone 0.5-1 mg/kg per day and one IV pulse of CYC per month for 6 months. Azathioprine was started as a remission-maintaining treatment. In ten of 20 patients, treatment was switched to MMF. The mean age at the time of diagnosis was 16.11 +/- 3.49 years, and the mean duration of follow-up was 49.6 +/- 27 months. Fourteen patients (70%) had complete remission, three (15%) had partial remission, one (5%) continued to have active disease, and two (10%) progressed to end-stage renal disease. Nine of the patients (45%) with complete remission had received AZA, and switching to MMF increased complete remission rate (additional five patients; 25%). In conclusion, short-term (6-month) IV bolus CYC treatment followed by AZA is a safe and effective treatment in children with severe lupus nephritis, and using MMF increases remission rate in resistant cases.

    Autoimmune liver diseases may be associated with extrahepatic autoimmune pathology. We report the case of a 52-year old woman who initially presented to the gastroenterology department for extreme fatigue, pale stools, dark urine and pruritus. Laboratory tests showed significant cholestasis and elevation of aminotransferase levels. Immunological tests revealed positive antinuclear (ANA=1:320) and antimitochondrial antibodies (AMA=1:40) with negative anti-smooth muscle and liver kidney microsomal type 1 antibodies. The biopsy was compatible with overlap syndrome type 1. The patient was commenced on immunosuppressive therapy according to standard of care (azathioprine 50mg, ursodeoxycholic acid and prednisone 0.5mg/kg), with moderate biochemical improvement. She subsequently developed proximal symmetrical weakness and cutaneous involvement and was diagnosed with biopsy-proven dermatomyositis. The immunosuppressive regimen was intensified to 150 mg azathioprine. At the three-month follow-up, her symptoms subsided and aminotransferases and muscle enzymes normalized. Upon further investigation the patient was diagnosed with autoimmune thyroiditis and antiphospholipid syndrome. To our knowledge, this is the first case of primary biliary cirrhosis - autoimmune hepatitis overlap syndrome associated with dermatomyositis, autoimmune thyroiditis and antiphospholipid syndrome.

    The orthotopic liver transplantation (OLT) program of the University of Liège was initiated in 1986. Between 1986 and December 1998, 150 adult OLT have been performed in our institution, including 18 liver retransplantations, 1 combined heart and liver transplantation and 3 combined liver and kidney transplantations. The aim of this study was to report the last 3 years of our experience. From January 1996 to November 1998, we performed 50 OLT on 49 patients. Three were retransplantations and two were combined liver and kidney transplantations. Fourty-three patients were transplanted for chronic liver disease and 6 for acute or subacute hepatopathy. Mean waiting time on the list was 4 weeks. Immunosuppression was based on triple therapy (cyclosporin A/tacrolimus, steroids, azathioprine), with steroid and azathioprine withdrawal in most of the patients after 3 months. In the chronic liver disease group, operative (< 30 days) survival was 95% (peroperative myocardial infarction in 2 patients). In the acute liver disease group, postoperative survival was 66%. No perioperative death occurred in 1997 and 1998. Actuarial one year survival was 87%. In our experience, OLT has become a safe procedure.

    Idiopathic inflammatory myopathy consists of dermatomyositis (DM), polymyositis (PM), inclusion body myositis (IBM) and necrotizing autoimmune myopathy (NAM). At all stages of myositis, physiotherapy is effective in improving muscle strength, endurance and in maintaining joint motion. In DM and PM the therapy is initiated with glucocorticosteroids. Steroid-sparing agents (azathioprine, methotrexate and cyclosporin A) are added to prevent Cushing's syndrome or an unsatisfactory response. Therapy can also be escalated with intravenous immunoglobulins. Tacrolimus and mycophenolate mofetil (MMF) were effective in small case series. Cyclophosphamide is restricted to patients not responding to previous agents. For treatment intensification immunoglobulins can also be combined with MMF. There is not enough evidence to routinely recommend rituximab. The results with TNF-alpha inhibitors and plasmapheresis were negative or inconsistent. In DM skin involvement responds to sun blockers, antimalarials, topical corticosteroids or calcineurin inhibitors. In NAM statins should be discontinued and treatment with prednisone and immunosuppressants initiated. In IBM a therapeutic trial with prednisone, methotrexate or azathioprine may be warranted, especially in cases in which the serum creatine kinase (CK) is elevated or an inflammatory infiltrate is present in the muscle biopsy.

    In general, cadaver kidney transplantation survival remains at 40-50% for the first year after transplantation. To compare the beneficial effect of a new immunosuppressive protocol to standard therapy (azathioprine and prednisone), we have studied 30 high risk first cadaveric renal allograft recipients who were randomly selected before (Group A, n.15) and after (Group B, n.15) 10/79. At 12 mos, actuarial graft survival of Group B is 75% compared to 46% in Group A. Actuarial patient survival for Group B is 94% for one year compared to 60% in Group A. We feel that these improved results are related to basic changes in our immunosuppressive protocol. These changes consist of: 1. Low doses of azathioprine and prednisolone (less than 1 mg/kg) with rapid reduction to very low levels (less than 0.3 mg/kg); 2. ALG administration at 30 mg/kg/day for 14 times; 3. Rapid placement (one month) on alternate day steroid therapy; 4. Elimination of steroids for the treatment of rejection; 5. Use of ALG (20 mg/kg/day for 10 days) for the treatment of rejection; 6. Use of ALG combined with modified lymph node irradiation for third rejection episodes; and 7. Long-term intermittent ALG administration provided that kidney function continues to be normal. The best immunosuppressive protocol is clearly the one associated with less morbidity and improved quality of life after transplantation. Our current protocol (Group B) provides the best results.

    Intrarenal vasoconstriction is a characteristic feature of CsA nephrotoxicity. The influence of nifedipine, a dihydropyridine calcium channel blocker and potent renal vasodilator, on renal haemodynamics was investigated in 11 cyclosporin A (CsA)- and 9 azathioprine (Aza)-treated normotensive long-term renal allograft recipients. Baseline Cr51-EDTA clearance and effective renal plasma flow (ERPF) were similar in both groups. Nifedipine 20 mg twice daily for 28 days significantly increased Cr51-EDTA clearance (+14.8%) in the CsA group; however, ERPF, renal vascular resistance (RVR), and filtration fraction did not change. Nifedipine did not influence renal haemodynamics in the azathioprine group. The increase in Cr51-EDTA clearance in the CsA group did not correlate with baseline renal function, CsA dose or whole blood levels, donor age, duration of graft, or renal functional reserve capacity. This study suggests that nifedipine confers a beneficial effect on renal haemodynamics in long-term CsA-treated renal allograft recipients and appears to improve renal function by a non-haemodynamic mechanism.

    Post-streptococcal glomerulonephritis (PSGN) generally has a good renal prognosis, and immunosuppressive therapies are not needed. However, a few patients present with severe acute kidney injury and extensive crescent formations. The etiology of such patients is not well known, and involvement of anti-neutrophil cytoplasmic antibodies is rarely reported. A 9-year-old girl with rapidly progressive nephritic syndrome was diagnosed with PSGN. A biopsy showed diffuse crescentic glomerulonephritis with immunoglobulin G and C3 deposits; moreover, humps were observed on electron microscopy. After she was administered methylprednisolone pulse therapy and intravenous cyclophosphamide, followed by prednisolone and azathioprine therapy, her urinary abnormalities improved and renal function normalized. However, the myeloperoxidase anti-neutrophil cytoplasmic antibody (MPO-ANCA) titers gradually increased. We speculated that PSGN may be augmented by increased MPO-ANCA levels. Therefore, the patient is currently being treated with losartan, enalapril, azathioprine, and prednisolone. Although the MPO-ANCA titer remains high, urinary findings show mild proteinuria and her renal function has been norma for 18 months since onset. A progressive clinical course and severe histological findings may indicate the involvement of ANCA in deterioration of condition in patients with PSGN. Furthermore, in such cases immunosuppressive therapies should be considered even in pediatric PSGN.

    2009-10-01

    Allergic and irritant contact dermatitis are important dermatological problems. Although the frequencies of positive reactions to a number of allergens have decreased during last 30 years because of better avoidance (and at least in part due to improved legislation), contact allergy to other agents is rising. The medical treatment starts from a correct identification of triggers of contact dermatitis which could allow patients to reduce or avoid exposure to these agents in future. A good clinical history, examination and immunological tests including patch testing are of crucial importance at this stage. Further management includes emollients, topical and oral corticosteroids, topical calcineurin inhibitors, azathioprine and ciclosporin. Methotrexate and alitretinoin are recent additions to the armamentarium of dermatologists who manage contact dermatitis.

  1. Autoimmune Hepatitis as a Unique Form of an Autoimmune Liver Disease: Immunological Aspects and Clinical Overview

    Hind I. Fallatah

    2012-01-01

    Full Text Available Autoimmune hepatitis (AIH is a unique form of immune-mediated disease that attacks the liver through a variety of immune mechanisms. The outcomes of AIH are either acute liver disease, which can be fatal, or, more commonly, chronic progressive liver disease, which can lead to decompensated liver cirrhosis if left untreated. AIH has characteristic immunological, and pathological, features that are important for the establishment of the diagnosis. More importantly, most patients with AIH have a favorable response to treatment with prednisolone and azathioprine, although some patients with refractory AIH or more aggressive disease require more potent immune-suppressant agents, such as cyclosporine or Mycophenolate Mofetil. In this paper, we discuss the immunological, pathological and clinical features of AIH, as well as the standard and alternative treatments for AIH.

    2009-01-01

    Autoimmune hepatitis (AIH) is a necroinflammatory liver disease of unknown etiology that occurs in children and adults of all ages. Characteristics are its autoimmune features, hyperglobulinemia (IgG), and the presence of circulating autoantibodies, as well as a response to immunosuppressant drugs. Current treatment consists of prednisone and azathioprine and in most patients this disease has become very treatable. Over the past 2 years, a couple of new insights into the genetic aspects, clinical course and treatment of AIH have been reported, which will be the focus of this review. In particular, we concentrate on genome-wide microsatellite analysis, a novel mouse model of AIH, the evaluation of a large AIH cohort for overlap syndromes,suggested novel criteria for the diagnosis of AIH, and the latest studies on treatment of AIH with budenoside and mycophenolate mofetil.

    2010-01-01

    During the last decades, the conventional therapy for autoimmune blistering diseases has been high-dose, long-term systemic corticosteroid and immunosuppressive agents or adjuvant drugs. Long-term, high-dose steroid therapy can result in serious adverse effects. The rationale for using adjuvant drugs is that concerns reducing the need for corticosteroids, and hence, their side effects, or it may result in better control of the disease, or both. Immunosuppressive agents are not free of adverse effects, however. Prolonged immune suppression may account for high rates of morbidity, disability, and possible death. There is no consensus about the first-choice adjuvant drug for the management of blistering autoimmune diseases. This contribution evaluates six adjuvant drugs-cyclophosphamide, azathioprine, cyclosporine, mycophenolate mofetil, intravenous immunoglobulin, and rituximab-and discusses the choice of a "winning drug" that is effective and safe.

    Full Text Available Autoimmune hepatitis (AIH is a chronic inflammatory liver disease of unknown aetiology usually requiring long-term immunosuppressive therapy. We present the case of an AIH patient who received long-term corticosteroids and azathioprine. As treatment for concomitant osteoporosis she was also treated with potent intravenous bisphosphonate (BP. This treatment was complicated by the development of BP-related osteonecrosis of the jaw (BRONJ. BRONJ is an uncommon complication of BP treatment regimes that occurs at increased frequency in the presence of other risk factors, including chronic inflammatory conditions. Our patient suffered from a severe and complicated clinical course of BRONJ which, despite adequate therapy, resulted in death of the patient. Here we discuss the risk factors for the development and clinical course of BRONJ in AIH and the implications for management of these patients.

    Maria Giovanna Danieli

    2012-01-01

    Full Text Available Sensory neuronopathy is described in association with the Sjögren's syndrome (SS. We studied a 55-year-old woman with a 4-year history of progressive asymmetric numbness, distal tingling, and burning sensation in upper and lower limbs. In a few months, she developed ataxia with increased hypoanaesthesia. Electrodiagnostic tests revealed undetectable distal and proximal sensory nerve action potential in upper and lower limbs. Cervical spine magnetic resonance showed a signal hyperintensity of posterior columns. Previous treatment with high-dose glucocorticoids and azathioprine was ineffective. A combined treatment with intravenous immunoglobulin and mycophenolate mofetil was followed by a progressive and persistent improvement. This case documented the efficacy and the safety of the coadministration of intravenous immunoglobulin and mycophenolate mofetil in sensory neuronopathy associated with SS refractory to conventional immunosuppressive therapy.

    We report the case of a 45-year-old female patient with an 18 month diagnosis of distal ulcerative colitis (proctosigmoiditis) of 18 months, who presented initially with allergy to salicylates, for which the disease was managed with corticosteroids and azathioprine and subsequently with Infliximab infusions, entering in remission. When she was about to receive her fifth Infliximab infusion she presented an exacerbation of her underlying disease with frequent stools with mucus, blood and tenesmus. Given that her initial diagnosis was made with a sigmoidoscopy we scheduled a total colonoscopy showing marked inflammation, erythema and friability limited to the recto-sigmoid mucosa, like at the disease onset, and when we reached the cecum an erythematous area circumscribed to the appendiceal orifice was observed, with a mucosal aspect identical to the described for the recto-sigmoid mucosa. The biopsies taken from that area were compatible with ulcerative colitis. We herein describe the details of the case and review the literature.

    The case of a patient who was initially diagnosed with Systemic Lupus Erythematosus, with subsequent documentation of Celiac Disease histologically and serologically is reported. The patient presented elevation of the aminotransferases, upon detection of the Celiac Disease which was initially attributed to the underlying disease. However, despite the complete resolution of her articular symptoms with a gluten-free diet, the liver chemistry abnormalities persisted. This led to consider an autoimmune hepatitis as the cause which was documented with a liver biopsy three months after the diagnosis of the celiac disease and under a strict gluten-free diet. Treatment with prednisone and azathioprine was initiated with complete normalization of aminotransferase levels. We present the sequence of events with the results and a review of the literature.

    Pancreatic islet transplantation is a treatment option for patients with type 1 diabetes (T1D), but pregnancy has generally not been advised for women after receiving an islet allograft. We hereby describe what is to our knowledge the first successful pregnancy and persistent graft function in a woman 4 years after her initial islet transplantation. A 37-year-old woman with brittle type 1 diabetes was transplanted with two separate islet graft infusions, eventually becoming insulin independent. Ten months after her second transplantation, her immunosuppression was switched from tacrolimus and sirolimus to tacrolimus, azathioprine, and prednisolone, due to her wish to become pregnant. She became pregnant one year later, and after 38 weeks of uncomplicated pregnancy, she gave birth to a healthy child by C-section. The current report suggests that pregnancy and childbirth can be accomplished after islet transplantation without loss of islet graft function.

    Muscle breakdown and repair were measured by metabolic balance techniques in a patient with polymyositis who was being treated with prednisolone and azathioprine. Changes in body muscle mass that had been estimated from nitrogen and phosphorus balances correlated with antropometric assessments of thigh muscle mass and quadriceps strength. Decline in muscle strength was associated with a net rate of muscle breakdown of 148 g/day. Recovery was associated with a net rate of muscle repair of up to 100 g/day. Early reduction in corticosteroid treatment appeared to enhance the rate of repair. Changes in the isometric contraction force of the quadriceps muscle (but not in clinical symptoms, plasma creatine kinase [CK] or erythrocyte sedimentation rate [ESR] were found to reliably indicate whether the muscle was in a state of breakdown or repair. Treatment of the individual patient may be quantitatively monitored by metabolic balance studies or, more simply, by measurement of muscle strength.

  11. Evolution of Collagenous Colitis into Severe and Extensive Ulcerative Colitis

    2007-01-01

    Full Text Available Collagenous colitis is an inflammatory mucosal disorder of the colon with distinctive histopathological features, including a thickened subepithelial collagen layer. The clinical course is usually benign, but serious complications, including death, may occur. In the present report, a 69-year-old woman with watery diarrhea and collagenous colitis developed bloody diarrhea that was refractory to treatment medications, including corticosteroids and azathioprine. Endoscopic and histopathological studies showed a focal neutrophilic inflammatory process that progressed to a diffuse and extensive form of colitis, eventually requiring total proctocolectomy. Careful histological review of the resected colon showed no evidence of persistent collagenous colitis. These findings suggest an important need for continued long-term follow-up of patients with collagenous colitis because superimposed and serious colonic complications may occur, including a severe and extensive pancolitis refractory to medications and necessitating total proctocolectomy.

    Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is an acquired, autoimmune peripheral neuropathy. Systemic lupus erythematosus (SLE) is a multisystemic, autoimmune disease that can affect the central nervous system in about 40% of patients, with prevalence and incidence unknown in the pediatric population due to lack of multicenter studies. We report the case of a 13-year-old Mexican boy, diagnosed with CIDP at the onset of SLE, beginning with progressive muscle weakness of lower and upper limbs, without affection of the central nervous system. The patient had positive ANA, antiDNAdc, antiBeta2glycoprotein, anti-cardiolipin, ANCA-C and X. He received intravenous immunoglobulin, cyclophosphamide, steroids, and azathioprine and showed clinical improvement. It is important to take into account the presence of peripheral neurological disorders in patients with pediatric SLE, considering CIDP as an uncommon presentation, making the diagnosis important for better treatment and evolution.

    2014-12-01

    Pharmacogenetic studies have been performed for almost all classes of drugs that have been used in IBD but very few have generated consistent findings or have been replicated. The genetic test that has been approved for clinical practice is TPMT testing prior to starting treatment with thiopurine drugs. Research in IBD pharmacogenetics has focused on prediction of drug efficacy and toxicity by identifying polymorphisms in the genes encoding enzymes that are involved in metabolic pathways. Recent research has mainly focused on therapeutic agents such as azathioprine, methotrexate, aminosalicylates, corticosteroids, infliximab and adalimumab. Future pharmaceutical trials should include pharmacogenetic research to test appropriate candidate genes in a prospective manner and correlate genetic associations with trial outcomes and relevant functional data.

    Full Text Available Ulcerative colitis (UC is a chronic idiopathic inflammatory disorder of colon. Frequency of UC is gradually increasing over few years worldwide. Prevalence is 35 to 100/100 000 people in USA, 1% of them are infants. UC develops in a genetically predisposed individual with altered intestinal immune response. An eight-month-old girl presented with loose bloody stool, growth failure, and moderate pallor. The girl was diagnosed as a case of UC by colonoscopy and biopsy. Treatment was thereafter started with immunosuppressive drugs. After initial induction therapy with parenteral steroid and infliximab, the patient is now on remission with azathioprine and mesalamine. UC is rare in Bangladesh, especially in children, and it is rarer during infancy. Several conditions like infective colitis, allergic colitis, Meckel′s diverticulitis, Crohn′s disease, etc. may mimic the features of UC. So, if a child presents with recurrent bloody diarrhea, UC should be considered as differential diagnosis.

  16. Generalized subcutaneous edema as a rare manifestation of dermatomyositis: clinical lesson from a rare feature.

    LENUS (Irish Health Repository)

    Haroon, Muhammad

    2011-04-01

    Generalized subcutaneous edema is a very rare manifestation of inflammatory myopathies. A 61-year-old woman presented with classic signs and symptoms of dermatomyositis. She was also noted to have generalized edema that was so florid that an alternative diagnosis was considered. Her disease was resistant to corticosteroids, azathioprine, and mycophenolate mofetil. Intravenous administration of immunoglobulins was started because of marked worsening of her disease-muscle weakness, generalized anasarca, and involvement of her bulbar muscles. This led to dramatic resolution of her subcutaneous edema and significant improvement of her skin and muscle disease. As the initial screen for malignancy was negative, a positron emission tomography-computed tomography scan was requested, which interestingly showed a metabolically active cervical tumor. Anasarca is an unusual manifestation of dermatomyositis. In treatment-refractory cases, it seems reasonable to consider positron emission tomography scan in excluding underlying malignant disease.

    2005-10-12

    In Crohn's disease therapeutic concepts are according to distinct conditions. Course of the disease, the individual disease pattern and the aim of treatment are of particular significance. Care of patients with Crohn's disease requires interdisciplinary cooperation between gastroenterologists and surgeons. Primary therapy in mild to moderate disease comprises aminosalicylates and budesonide. Treatment of refractory or severe cases are corticosteroids. Immunosuppressive therapy is indicated in all kinds of complicated disease. First line immunosuppressants are Azathioprine and 6-Mercaptopurine while Methotrexate, Infliximab, Mycophenolatmofetil and other compounds represent alternative or rescue medications. Maintenance of remission should not be done on a regular basis but rather regarding the individual patients' situation. Risks have to be carefully balanced with possible benefits. The most important aim of treatment is quality of life.

    Inflammatory bowel diseases (IBD) are chronic inflammatory conditions of the gastrointestinal tract,which clinically present as one of two disorders, Crohn's disease or ulcerative colitis. Mainstays of drug treatments for IBD include aminosalicylates, corticosteroids and immunosuppressants such as azathioprine, methotrexate and cyclosporin. Advances in basic research of the pathophysiological process in IBD have been applied to generate a variety of new therapeutics targeting at different levels of the inflammatory processes. New therapies are classified as: (1) Anti-TNFα antibodies; (2) Recombinant cytokines; (3) Selective adhesion blockade;(4) Growth factors; (5) Innate immunostimulation; (6) Nucleic acid based therapies; (7) Gene therapy; (8) Autologous bone-marrow transplantation; (9) Helminths and (10) Extracorporeal immunomodulation. All treatments have the potential to provide more effective and safe treatment for IBD.

  19. Is the sinusoidal obstructive syndrome post-liver transplantation a pathologic entity with a multifactorial etiology?

    Directory of Open Access Journals (Sweden)

    Luis Miguel Marín-Gómez

    2015-04-01

    Full Text Available The sinusoidal obstructive syndrome is a complication typically associated with hematopoietic stem cell transplantation. This syndrome, more commonly known as veno-occlusive disease, has also been described after liver transplantation. It can have a life-threatening course. Herein, we describe the hepatic graft loss secondary to the development of a sinusoidal obstructive syndrome after a severe acute cellular rejection and toxic levels of once daily modified released tacrolimus (TAC. We discuss the role of the endotheliitis of acute rejection and toxic metabolites of some immunosuppressants such as azathioprine and TAC. Based on the current scientific evidence, we contemplate the possibility that the etiology of sinusoidal obstruction syndrome post-liver transplantation is multifactorial.

    1998-02-01

    Inflammatory bowel disease represents chronic idiopathic disorders which involve either the colon exclusively (ulcerative colitis) of any part of the gastrointestinal tract (Crohn's disease). The course of these entities is typified by periods of symptomatic exacerbation interspersed with clinical remissions. Management is based upon regimens which decrease mucosal inflammation. Colonic disease distal to the splenic flexure may be treated with topical therapy, but other regions generally necessitate oral therapy. Currently used medications include the aminosalicylates, glucocorticoids, antibiotics and immunomodulators. The immunomodulator class of medications includes azathioprine, 6-mercaptopurine, cyclosporine A and methotrexate. Newer agents include short-chain fatty acids, omega-3 fatty acids and antibodies directed to tumor necrosis factor. Medical management also occasionally involves optimizing nutritional status with the addition of elemental diets or total parenteral nutrition. Management of specific clinical presentations is discussed.

  1. Hepatotoxicity by Drugs: The Most Common Implicated Agents.

    Björnsson, Einar S

    2016-02-06

    Idiosyncratic drug-induced liver injury (DILI) is an underreported and underestimated adverse drug reaction. Information on the documented hepatotoxicity of drugs has recently been made available by a website that can be accessed in the public domain: LiverTox (http://livertox.nlm.nih.gov). According to critical analysis of the hepatotoxicity of drugs in LiverTox, 53% of drugs had at least one case report of convincing reports of liver injury. Only 48 drugs had more than 50 case reports of DILI. Amoxicillin-clavulanate is the most commonly implicated agent leading to DILI in the prospective series. In a recent prospective study, liver injury due to amoxicillin-clavulanate was found to occur in approximately one out of 2300 users. Drugs with the highest risk of DILI in this study were azathioprine and infliximab.

    2014-01-01

    Neuromyelitis optica (NMO) is an inflammatory demyelinating disease of the central nervous system that selectively targets the optic nerve and spinal cord, although it may also target certain areas of the brain. The majority of cases are associated with relapses. A specific biomarker, an autoantibody that targets aquaporin-4, is present in the majority of patients and facilitates the diagnosis. Detection of this biomarker in serum has enabled recognition of an expanded spectrum of clinical disorders that previously would not have met diagnostic criteria for NMO. Aquaporin-4 IgG1 autoantibodies are pathogenic and produce lesions of the brain when injected intracerebrally or systemically. The clinical course of NMO is dominated by acute attacks. Progressive worsening of disability, as occurs in prototypic multiple sclerosis, is distinctly unusual. Corticosteroids and plasma exchange are useful for management of acute attacks. Several treatments used to prevent attacks of multiple sclerosis are ineffective in this condition; effective immunotherapies include azathioprine, mycophenolate mofetil and rituximab.

    2015-03-27

    The diagnosis of acute autoimmune rheumatic disorders in sickle cell disease (SCD) can be challenging. Polymyositis is an inflammatory myopathy which, like SCD, may present with myalgia but is usually associated with proximal muscle weakness. We describe an adolescent boy presenting with limb pain, difficulty in mobilisation, with progressive loss of motor function and later bulbar weakness. Investigations showed massive elevation of creatine kinase, and MRI and muscle biopsy findings consistent with severe polymyositis. The patient was treated with corticosteroids, intravenous immunoglobulin and intensive rehabilitation therapy. He made a good recovery and was discharged on azathioprine and prednisolone. In the context of SCD, multisystem symptoms, unexplained muscle pain and weakness, unresponsive to conventional treatment in the presence of steady state haemoglobin, should alert the clinician to autoimmune phenomena. Key factors in making a diagnosis are an autoimmune screen and early discussion with a rheumatology expert.

    Secondary amyloidosis (AA) is a severe complication of progressed Crohn’s disease (CD) for which no effective treatment exists. We present the exceptional case of a 33 year-old male with moderate renal failure and proteinuria, who was simultaneously diagnosed with AA amyloid nephropathy and oligosymptomatic CD. He was treated with infliximab at 5mg/kg/8 weeks for 4 years, azathioprine at 1-1.5mg/kg/day (first year) and renin-angiotensin-aldosterone system blockers, with no complications. Treatment caused a decrease in proteinuria, improved renal function, and improved inflammatory parameters over time. Inspired by this case, we performed a review of the medical literature and found that infliximab could be a useful tool in the early treatment of amyloidosis secondary to CD.

    2011-09-01

    Full Text Available The treatment of rheumatoid arthritis traditionally includes symptomatic drugs, showing a prompt action on pain and infl ammation, but without any infl uence on disease progression, and other drugs that could modify the disease course and occasionally induce clinical remission (DMARDs or disease modifying anti-rheumatic drugs. This review describes the historical steps that led to the use of the main DMARDs in rheumatoid arthritis, such as gold salts, sulphasalazine, chloroquine and hydroxychloroquine, D-penicillamine, and other immunoactive drugs, including methotrexate, azathioprine, cyclosporin and lefl unomide. The historical evolution of use of these drugs is then discussed, including the strategy of progressive (“therapeutic pyramid” or of more aggressive treatment, through the simultaneous use of two or more DMARDs (“combination therapy”.

    Tesar, V; Hruskova, Z

    2012-08-01

    Patient survival and renal survival of patients with lupus nephritis improved, but still in a significant proportion of patients the disease progresses to end-stage renal failure, possibly at least partly due to slow and incomplete response to induction treatment and high relapse rate on the maintenance treatment. Mycophenolate mofetil was recently demonstrated to be a comparably effective and safe induction treatment of lupus nephritis as high-dose cyclophosphamide pulses, in Caucasian patients it has become a reasonable alternative to low-dose cyclophosphamide pulses according to the EUROLUPUS protocol. Mycophenolate was shown to be more effective than azathioprine in the maintenance treatment and is currently the treatment of choice for this phase of the disease. Rituximab should be reserved for patients refractory (or intolerant) to cyclophosphamide and/or mycophenolate. Therapy of lupus nephritis should be individually tailored; more aggressive therapy should be reserved for patients at high risk for renal dysfunction and its progression.

    We report here a case of systemic lupus erythematosus with severe, active pauci-immune necrotizing and crescentic glomerulonephritis. This patient had been diagnosed of a lupus nephritis type III previously and treated with steroids and azathioprine. After a renal symptomless period of nine years, she developed heavy proteinuria and hypertension. A second kidney biopsy was then performed. The pathological study disclosed a pauci-immune necrotizing crescentic and segmental glomerulonephritis. The absence of subendothelial and mesangial deposits was confirmed by both immunofluorescent microscopy and electron microscopy. The simultaneous immunological study showed normal ANCA levels while complement, anti-dsDNA and ANA were altered. The patient was treated with steroids and cyclophosphamide eith good response. This case points out the possibility previously recognized by others of an association between lupus and an pauci-immune necrotizing glomerulonephritis.

    2005-01-01

    Full Text Available Infliximab, a monoclonal antibody directed against tumour necrosis factor-alpha, is an effective therapy for Crohn's disease. Though uncommon, serious opportunistic infections, including reactivation of tuberculosis, have occurred in patients after infliximab administration. Meningitis caused by Listeria monocytogenes developed in a 37-year-old man six days after the second infusion of infliximab. The patient, who also was treated with azathioprine and corticosteroids, had an uneventful recovery after a course of antibiotics. Several other recent reports have implicated infliximab therapy in the development of severe Listeria infections, particularly meningitis and sepsis. With the increasing use of tumour necrosis factor-alpha-neutralizing agents, clinicians should be aware of the risk of opportunistic infections caused by L monocytogenes in patients with Crohn's disease following infliximab treatment.

    Full Text Available Importance. Rituximab was not effective in ameliorating the hearing loss in a patient with atypical Cogan’s syndrome. Observations. We report the case of a patient who developed acute bilateral uveitis and sensorineural hearing loss. A diagnosis of atypical Cogan’s syndrome was made. The patient’s hearing loss did not improve despite high dose steroids and azathioprine. Rituximab was administered given a recent report of its efficacy in a patient with refractory disease; however, our patient’s hearing loss did not improve. Conclusion. Hearing loss in Cogan’s syndrome is difficult to treat. Though rituximab was ineffective in our case, earlier administration in the disease course could be effective for future patients.

    Time, times and timing are key words in inflammatory bowel diseases (IBD).The leifmotif of this issue or World Journal of Gastroenterology is time. We have asked experts to review on the epidemiology of these diseases over time,the changes in innate immunity that could be present in the first time, and then the timing of key treatments. The correct time of using azathioprine, mercaptopurine, infliximab, cyclosporine and surgery are reviewed.We have chosen experts with not only great clinical expertise but also personal interest in clinical and basic investigation. Our goal in this monograph is to get an idea not only of the present but of the immediate future in some of the key management issues in IBD. To this end, we think that the authors are the most adequate.

    2007-01-01

    We report a 12 years old female patient with an overlap syndrome involving autoimmune hepatitis (ALM) and systemic lupus erythematosus (SLE). The patient presented with jaundice, hepatosplenomegaly, malAlse, polyarthralgia, arthritis and butterfly rash on the face. Laboratory tests revealed severe liver dysfunction, Coombs positive hemolytic anemia and a positive ANA/ anti-dsDNA test. Renal biopsy showed class IIA kidney disease, while liver biopsy showed chronic hepatitis with severe inflammatory activity. The patient satisfied the international criteria for both SLE and ALM. Clinical symptoms and laboratory findings of SLE improved with high dose treatment with corticosteroids and azathioprine, however, remission of the liver disease could not be achieved. Repeat biopsy of the liver after three years of therapy revealed ongoing chronic hepatitis with high level of inflammatory activity. The present case indicates that children with liver dysfunction and SLE should be investigated for ALM. There is much diagnostic and therapeutic dilemma in patients with ALH-SLE overlap syndrome.

    Ultrasound examination of a para 1, gravida 2, 26 y.o. showed severe hydrocephalus and polyhydramnios. Amniocentesis was performed at 27 weeks. High resolution chromosome analysis revealed a karyotype with a 9;12 translocation, a pericentric inversion of chromosome 11, and a paracentric inversion of chromosome 13. Parental chromosome studies were normal. The mother was not on medication prior to her pregnancy and there was no known exposure to radiation. Delivery was at 34 weeks gestation. The phenotype consisted of micrognathia, low set ears, hypertelorism, and hydrodcephaly. Review of the literature revealed a single report with multiple de novo aberrations consisting of a 6;14 translocation and a deleted 7. This was diagnosed in the child of a woman with systemic lupus erythematous treated with azathioprine. These types of abnormalities have been known to be induced by chemical and radiation exposure. High resolution banding combined with molecular studies presently improve our ability to detect subtle structural aberrations.

    Psoriasis is a common, chronic, inflammatory, multisystem disease with predominantly skin and joint manifestations affecting approximately 2% of the population. In this fourth of 6 sections of the guidelines of care for psoriasis, we discuss the use of traditional systemic medications for the treatment of patients with psoriasis. Treatment should be tailored to meet individual patients' needs. We will discuss in detail the efficacy and safety, and offer recommendations for the use of the 3 most commonly used, and approved, traditional systemic agents: methotrexate, cyclosporine, and acitretin. We will also briefly discuss the available data for the use of azathioprine, fumaric acid esters, hydroxyurea, leflunomide, mycophenolate mofetil, sulfasalazine, tacrolimus, and 6-thioguanine in psoriasis.

    The diagnosis of acute autoimmune rheumatic disorders in sickle cell disease (SCD) can be challenging. Polymyositis is an inflammatory myopathy which, like SCD, may present with myalgia but is usually associated with proximal muscle weakness. We describe an adolescent boy presenting with limb pain, difficulty in mobilisation, with progressive loss of motor function and later bulbar weakness. Investigations showed massive elevation of creatine kinase, and MRI and muscle biopsy findings consistent with severe polymyositis. The patient was treated with corticosteroids, intravenous immunoglobulin and intensive rehabilitation therapy. He made a good recovery and was discharged on azathioprine and prednisolone. In the context of SCD, multisystem symptoms, unexplained muscle pain and weakness, unresponsive to conventional treatment in the presence of steady state haemoglobin, should alert the clinician to autoimmune phenomena. Key factors in making a diagnosis are an autoimmune screen and early discussion with a rheumatology expert. PMID:25819817

    Methotrexate has been used an immunomodulator in many autoimmune diseases,including inflammatory bowel disease. However,many physicians are unfamiliar or uncomfortable with its use in the management of inflammatory bowel disease. We summarize the data for use of methotrexate in common clinical scenarios:(1) steroid dependant Crohn’s disease(CD);(2) maintenance of remission in steroid free CD;(3) azathioprine failures in CD;(4) in combination therapy with Anti-TNF agents in CD;(5) decreasing antibody formation to Anti-TNF therapy in CD;(6) management of fistulizing disease in CD; and(7) as well as induction and maintenance of remission in ulcerative colitis. An easy to use algorithm is provided for the busy clinician to access and safely prescribe methotrexate for their inflammatory bowel disease patients.

    Full Text Available Abstract Objective Behcet's is an idiopathic multi-organ syndrome, which may have onset during childhood. Vascular involvement is uncommon, with rarely reported coronary aneurysm formation. We present a case report of a teenager girl who developed recalcitrant life-threatening Behcet's vasculitis, involving both small and large venous and arterial systems including a giant coronary aneurysm. Case report De-identified data were collected retrospectively in case report format. Although our sixteen year old female with Behcet's vasculitis had resolution of many arterial aneurysms, she had persistent venous thrombosis of large vessels, as well as persistent, giant arterial aneurysms requiring intra-arterial coiling of a lumbar artery and coronary bypass grafting despite intensive immunosuppression including glucocorticoids, cyclophosphamide, infliximab, methotrexate, azathioprine and intravenous immunoglobulin. Conclusions Vascular manifestations may be seen in Behcet's syndrome, including asymptomatic coronary aneurysm, which may be refractory to immunosuppression and ultimately require surgical intervention. Increased awareness is essential for prompt diagnosis and management.

    The current established drugs used to treat inflammatory bowel disease include glucocorticoids includingnewer agent budesonide, sulfasalazine and 5-ASA compounds such as Asacol, Pentasa, Dipentum andBalsalazide and immunomodulatory agents such as azathioprine, and 6-mercaptopurine. Additional drugswhich have been found to be useful, particularly in refractory cases of Crohn's disease including fistulizingtype of Crohn's disease, include cyclosporine A, methotrexate, humanized antibody against TNFa(cA2),FK506, IL-10, IL-11 and Probiotics. Various agents, whether used alone or in combination, have to betailored for each patient and none is ideal. Exciting new developments directed against proinflammatorypathways, cytokines, free oxygen radicals and cell surface related immune targets are areas of intense recentinvestigations and many novel therapeutic agents are expected to be available in the near future for medicaltreatment of inflammatory bowel disease.

    Full Text Available Pemphigus vulgaris (PV is a life threatening autoimmune blistering disease of skin and mucous membranes. Advent of systemic steroids has greatly reduced the mortality rate. However, steroids and adjuvant immunosuppressive therapy are nowadays frequent contributory agents of morbidity and mortality of PV. Mycophenolate mofetil (MMF has been reported to be an effective adjuvant to systemic steroids. It helps in increasing the immunosuppressive effect and minimizing the toxicities by steroid sparing effect. However, its efficacy in refractory cases of PV is not well documented. The lowest possible dose with satisfactory therapeutic efficacy and least side effects is known. We used MMF 1 g/day and systemic steroids in 3 Indian patients with pemphigus vulgaris who were resistant to systemic steroid monotherapy or combination treatment with azathioprine. In our experience, MMF offers an effective adjuvant with minimal side-effects in the treatment of resistant PV.

    A 48-year-old female with severe ulcerative colitis refractory to conventional therapy was referred to our facility for management. The patient showed extensive ulcerative colitis since the age of 20 years and had failed therapy with 5-aminosalicylic acid agents and azathioprine. The disease remained active despite treatment with steroids and cyclosporine. The clinical and endoscopic parameters were consistent with severe disease. Infectious precipitants were ruled out. Given the severity of the disease and in order to avoid a colectomy, we started the patient on infliximab therapy. A dramatic clinical and endoscopic response was observed and she remained in remission at the end of a 1-year follow-up period. We discuss findings in the literature regarding the use of infliximab therapy in patients with ulcerative colitis who have failed steroids and cyclosporine.

    2015-05-01

    The field of pharmacogenomics was initiated in the 1950s and began to thrive after the completion of the human genome project 10 years ago. Thus far, more than 100 drug labels and clinical guidelines referring to pharmacogenomic biomarkers have been published, and several key pharmacogenomic markers for either drug safety or efficacy have been identified and subsequently adopted in clinical practice as pre-treatment genetic tests. However, a tremendous variation of genetic backgrounds exists between different ethnic groups. The application of pharmacogenomics in the Chinese population is still a long way off, since the published guidelines issued by the organizations such as US Food and Drug Administration require further confirmation in the Chinese population. This review highlights important pharmacogenomic discoveries in the Chinese population and compares the Chinese population with other nations regarding the pharmacogenomics of five most commonly used drugs, ie, tacrolimus, cyclosporine A, warfarin, cyclophosphamide and azathioprine.

    Full Text Available Abstract Introduction Strongyloides stercoralis infection affects hundreds of millions of people worldwide. As immigration rates and international travel increase, so does the number of cases of strongyloidiasis in the United States. Although described both in immigrant and in immunosuppressed populations, hyperinfection and dissemination of S. stercoralis following the initiation of antiparasitic medication is a previously unreported phenomenon. Case presentation Here we describe the case of a 38-year-old immunocompromised woman with systemic lupus erythematosus, who developed disseminated disease following treatment with albendazole (400 mg every 12 hours. Notably the patient was receiving oral prednisone (10 mg once daily, azathioprine (50 mg twice daily, and hydroxychloroquine (400 mg daily at the time of hospitalization. The patient was subsequently treated successfully with ivermectin (200 mcg/kg daily. Conclusion The reader should be aware that dissemination of S. stercoralis can occur even after the initiation of antiparasitic medication.

    Full Text Available Abstract Background Cellulitis caused by Mycobacterium avium-intracellulare has rarely been described. Mycobacterium avium-intracellulare is a rare cause of septic arthritis after intra-articular injection, though the causative role of injection is difficult to ascertain in such cases. Case presentation A 57-year-old with rheumatoid arthritis treated with prednisone and azathioprine developed bilateral painful degenerative shoulder arthritis. After corticosteroid injections into both acromioclavicular joints, he developed bilateral cellulitis centered over the injection sites. Skin biopsy showed non-caseating granulomas, and culture grew Mycobacterium avium-intracellulare. Joint aspiration also revealed Mycobacterium avium-intracellulare infection. Conclusion Although rare, skin and joint infections caused by Mycobacterium avium-intracellulare should be considered in any immunocompromised host, particularly after intra-articular injection. Stains for acid-fast bacilli may be negative in pathologic samples even in the presence of infection; cultures of tissue specimens should always be obtained.

    Crohn's disease is a chronic, progressive disabling condition ultimately leading to stricturing and/or penetrating complications. The need for surgery may be as high as 70% in patients with severe active disease or complications. However, relapse may develop in a significant proportion of the patients after surgery leading to frequent re-operations. Despite emerging data, postoperative prevention is still controversial. After careful evaluation of the individual risk a tailored therapy should be considered. In patients with small risk for relapse mesalazine or in selected cases no-treatment may be an option. In patients with a moderate-to-high risk azathioprine should be considered together with metronidazole in the three months. Follow-up ileocolonoscopy 6-12 months after the surgery is helpful in the determination of endoscopic severity and may assist in the optimization of the therapy. In most severe cases anti-TNF agents may be appropriate for postoperative prevention and therapy.

    PURPOSE OF REVIEW: Renal dysfunction due to calcineurin inhibitor (CNI) toxicity is a major clinical problem in cardiac transplantation. The aim of the article is to review the efficacy and safety of various renal sparing strategies in cardiac transplantation. RECENT FINDINGS: Small studies have...... documented that late initiation of CNI is safe in patients treated with induction therapy at the time of transplantation. Use of mycophenolate is superior when compared with azathioprine to allow for CNI reduction. More substantial reduction in CNI levels is safe and effective with the introduction...... of sirolimus or everolimus. However, studies that use very early CNI discontinuation have found an increased risk of allograft rejection, and this strategy requires further study before it can be routinely recommended. CNI discontinuation late after cardiac transplantation seems more effective than CNI...

  10. Clinical utility of labeled cells for detection of allograft rejection and myocardial infarction

    1984-07-01

    The choice of a specific radiolabeled blood component for use in detection of allograft rejection depends on several factors including the immunosuppressive agents used, the type of organ allografted, and particularly the length of time the allograft resides in the host and the duration of rejection. To date, only the use of 111In-labeled platelets in renal allograft recipients immunosuppressed with azathioprine and corticosteroids has shown clinical promise in the detection of early allograft rejection. Radiolabeled blood components are unlikely to play a significant role in detection of myocardial infarction. The use of these agents for monitoring therapeutic interventions or as indicators of prognosis in patients with myocardial infarction continues to be investigated.

    To investigate the effect of oral nifedipine, a calcium channel blocker known not to modify cyclosporin A (CyA) pharmacokinetics, on immediate transplant function and CyA nephrotoxicity, 68 adult renal transplant recipients were pre-operatively randomized to one of three regimes: A (high-dose CyA, initial dose 17 mg/kg per day, maintenance dose 7 mg/kg per day); B (regime A plus oral nifedipine); C low-dose CyA, initial dose 10 mg/kg per day, maintenance 4 mg/kg per day plus azathioprine 1 mg/kg per day). All three groups received identical steroid regimes. Calcium channel blockers of all types were avoided in groups A and C. Delayed graft function (dialysis dependence by day 4) was seen least frequently in group B (P nifedipine significantly improves immediate and medium-term graft function.

    Salmonella enterica serovar Minnesota is a rarely isolated organism in clinical samples mainly grown from stool cultures. Sepsis due to Salmonella is known in severely immunocompromised patients, but so far urosepsis due to S. enterica serovar Minnesota has not been described. We report a case of a 31-year-old patient suffering from Crohn's disease treated with infliximab and azathioprine, in whom was implanted a double-J ureteric catheter for urolithiasis. The patient presented with urinary tract infection and severe sepsis. S. enterica serovar Minnesota was grown from urine and blood cultures. After empiric antimicrobial treatment with meropenem and vancomycin, treatment was changed to ceftriaxone. Antimicrobial treatment was continued for a total of 3 weeks without evidence of Salmonella recurrence on follow-up visits. Salmonella spp. rarely cause urinary tract infection and sepsis. However, in immunocompromised patients, non-typhoidal salmonellosis merits a thorough clinical and microbiological evaluation.

    Full Text Available A 52-year-old woman undergoing azathioprine treatment for rheumatoid arthritis developed acute retinal necrosis a month after intravitreal dexamethasone (Ozurdex ® implantation for posterior uveitis in the left eye. Varicella zoster virus (VZV DNA was detected in the anterior chamber and vitreous samples on polymerase chain reaction (PCR analysis. Retinal detachment occurred despite systemic and intravitreal antiviral therapy. Favorable structural and functional outcomes were achieved after retinal surgery with silicone oil. To the authors’ knowledge, this is the first reported case of acute retinal necrosis following placement of an Ozurdex® implant. Physicians practicing Ozurdex® implantations should be aware of this unusual but devastating complication. Extra caution and frequent follow-up are required in all immunocompromised patients receiving Ozurdex® implantation.

The laboratory findings revealed hemolytic anemia and direct antiglobulin test was positive. With a diagnosis of autoimmune hemolytic anemia (AIHA, prednisolone was started but was ineffective after 1 month of therapy. A bone marrow trephine biopsy revealed pure red cell aplasia (PRCA showing severe erythroid hypoplasia. The case was considered PRCA following AIHA. This combination without clear underlying disease is rare. Human parvovirus B19 infection was not detected in the marrow aspirate during reticulocytopenia. The patient received azathioprine, and PRCA improved but significant hemolysis was once again documented with a high reticulocyte count. The short time interval between AIHA and PRCA phase suggested an increased possibility of the evolution of a single disease.

    2013-03-01

    Idiopathic pulmonary hemosiderosis (IPH), a subtype of diffuse alveolar hemorrhage is a rare condition, first described by Virchow in 1864. Historically, it manifests in children in the first decade of life with the combination of hemoptysis, iron deficiency anemia, and alveolar infiltrates on chest radiograph. More recently, diffuse alveolar hemorrhage has been classified by the absence or presence of pulmonary capillaritis (PC), the latter carrying a potential for a poorer outcome. While systemic corticosteroids remain the first line treatment option, other immune modulators have been trailed including hydroxychloroquine, azathioprine, 6-mercaptopurine, and cyclophosphamide with varying results. Our case demonstrates for the first time, the successful use of intravenous cyclophosphamide in the management of chronic idiopathic PC.

    Full Text Available Disseminated strongyloidiasis is a rare manifestation in patients on immunosuppressive drugs. We report two cases of fatal disseminated Strongyloides stercoralis infestation. The first was in a patient of pemphigus vulgaris who developed an exacerbation of symptoms, one year after diagnosis and was given intravenous dexamethasone and azathioprine and in the third week of hospitalization developed features of septicemia, respiratory failure and petechial hemorrhages which were proven to be due to disseminated strongyloidiasis. The second patient was diagnosed to have stage IV diffuse large cell type of non-Hodgkin lymphoma and after the second cycle of chemotherapy, developed generalized symptoms of septicemia, respiratory failure, purpuric macules and patches. This was also proven to be disseminated strongyloidiasis.

    Sinha, Animesh A; Hoffman, Melissa B; Janicke, Elise C

    2015-04-01

    The therapeutic management of pemphigus vulgaris (PV) is centered around immunosuppression, which can be generalized, as in the use of corticosteroids or steroid sparing agents, or specific, as in therapeutic blockage of autoantibody production, certain cytokines, or signaling pathways. Currently, the backbone of treatment for PV, particularly, first line therapy, remains systemic corticosteroids. Although very effective, the significant side effects of long-term corticosteroid usage are well documented. Adjunctive therapies aim to eliminate, or at least decrease, the necessary dose of corticosteroids. Specifically, azathioprine, cyclophosphamide, methotrexate, cyclosporine, mycophenolate mofetil and dapsone are now widely used in PV. Intravenous immunoglobulin (IVIG), plasmapheresis, immunoadsorption, and most recently, rituximab, are other members of the therapeutic armamentarium. However, despite the widening range of treatment options in PV, well-controlled clinical trials and consensus guidelines are lacking.

    2015-01-01

    Pediatric chronic inflammatory demyelinating polyneuropathy (CIDP) is an uncommon acquired disorder of unknown cause, presumed to have an immunological basis. We report 20 patients seen at Children's Hospital Los Angeles over a period of 10 years. The outcome of our patients was favorable in a vast majority with good response to various treatments instituted. However, residual neurologic deficit was common. The choice of treatment modality was empirical and selected by the treating neurologist. Intravenous immunoglobulin (IVIG) and corticosteroids were most commonly utilized for treatment. Plasmapheresis, mycophenolate mofetil, rituximab, cyclophosphamide, azathioprine, and abatacept were added if the patients were refractory to IVIG or became corticosteroid dependent. The spectrum of disease severity ranged from a single monophasic episode, to multiphasic with infrequent relapses with good response to IVIG, to progressive disease refractory to multiple therapies.

    2016-02-01

    Erythromelalgia may be primary or secondary to an underlying medical condition. Association with small fiber neuropathy and axonal large fiber peripheral neuropathy has been described. Erythromelalgia in the setting of acquired demyelinating neuropathy has not been reported. We report a 52-year-old woman with severe erythromelalgia, pain and burning, progressive weakness, hyporeflexia and distal pan-sensory deficits. Cerebrospinal fluid protein was 219 mg/dL. Nerve conduction study revealed extreme (ten-fold) prolongation of distal motor latencies, markedly slow motor nerve conduction, reduced terminal latency index, reduced distal compound muscle action potential (CMAP) amplitude, possible conduction blocks, and distal denervation. Treatment with intravenous immunoglobulin, prednisone and azathioprine resulted in marked clinical and electrophysiological improvement. Our patient fulfills the diagnostic criteria for chronic inflammatory demyelinating polyneuropathy (CIDP); however, the unique electrodiagnostic features and presentation with erythromelalgia may represent a CIDP variant or a novel dysimmune neuropathy, or may partly be related to neurotoxic effects of prior alcohol abuse.

    Full Text Available Neuromyelitis optica (NMO is an inflammatory demyelinating disease that preferentially affects the optic nerves and spinal cord. It has a worldwide distribution and distinctive clinical, neuroimaging and laboratory findings that distinguish it from multiple sclerosis. In most cases there is a long interval between the optic neuritis and myelitis but approximately 10 to 20% can have near simultaneous occurrence of both. We report a case of NMO presenting with symptoms and signs of optic neuritis and transverse myelitis which was later confirmed by neuroimaging and laboratory findings. The acute attack was treated with pulse therapy of corticosteroid and subsequently the patient was maintained on Azathioprine and tapering dose of oral steroid. This case highlights a neurological disorder that is increasing in prominence and may become more relevant in our region with increased diagnostic utility of antibody testing.

  3. Clinical utility of thiopurine S-methyltransferase genotyping.

    Science.gov (United States)

    Corominas, Hèctor; Baiget, Montserrat

    2004-01-01

    Thiopurine S-methyltransferase (TPMT) is a cytosolic enzyme that plays a major role in the metabolism of thiopurine drugs such as mercaptopurine and azathioprine. The interindividual differences in response to thiopurine administration is in part due to the presence of genetic polymorphisms in the gene that regulates TPMT activity. TPMT genotype correlates well with the in vivo enzyme activity within erythrocytes. Patients with genetically determined decreased TPMT activity develop severe myelosuppression when treated with standard doses of thiopurine drugs because an excess of thioguanine nucleotides accumulates in hematopoietic tissues. TPMT genotyping provides clinicians with a reliable method for identifying TPMT-deficient patients who can benefit from low doses of thiopurine drugs in order to reduce the risk of developing adverse effects. Moreover, the administration of higher doses of the drug could improve therapeutic response in patients in whom the TPMT genotyping demonstrates the absence of mutated alleles.

    Lambert-Eaton myasthenic syndrome (LEMS) is an autoinmune idiopathic or paraneoplastic syndrome producing antibodies agaisnt presynaptic voltage calcium channels. The clinical features of patients with LEMS are muscle weakness and autonomic dysfunction. We report a 40 years old man with a four years history of proximal weakness, absent tendon reflexes and dry mouth. The diagnosis was confirmed by characteristic electromyographic findings, showing a low-amplitude muscle response that increased dramatically after activation. Circulating antibodies to voltage-gated calcium channel were present. The search for malignant tumors was negative. The patient was treated with prednisone and azathioprine and after four months, he was able to walk and signs of autonomic dysfunction started to subside.

    Full Text Available Epidermolysis bullosa acquisita (EBA is a chronic, autoimmune condition involving the skin and mucous membranes. Symptomatic mucosal involvement is rare, but can impact on quality of life, due to esophageal strictures and dysphagia. We report a case involving a 60-year-old male presenting with bullous skin lesions on areas of friction on his hands, feet and mouth. Milia were visible on some healed areas. Biopsy showed a subepidermal vesicle. Direct immunofluorescence showed intense linear junctional IgG and C3 at the dermo-epidermal junction. Serological tests also supported the diagnosis of EBA. Screening tests for underlying malignancies were negative. Despite treatment with systemic steroids, the patient developed increasing dysphagia, requiring further investigation with esophagoscopy and a barium swallow. Confirmation of extensive esophageal stricturing prompted adjustment of medications including an increase in systemic steroids and addition of azathioprine. Currently, the patient′s disease remains under control, with improvement in all his symptoms and return of anti-basement membrane antibody levels to normal, whilst he remains on azathioprine 150 mg daily and prednisolone 5 mg daily. This case highlights the fact that the treatment of a given patient with EBA depends on severity of disease and co-morbid symptoms. Newer immunoglobulin and biological therapies have shown promise in treatment resistant disease. Considering that long-term immunosuppressants or biologicals will be required, potential side effects of the drugs should be considered. If further deterioration occurs in this patient, cyclosporin A or intravenous immunoglobulin (IV Ig will be considered. Vigilance for associated co-morbidities, especially malignancies, should always be maintained.

The authors report the first case of a successful maternal-fetal outcome in a pregnant patient with systemic lupus erythematosus-associated pulmonary arterial hypertension treated with sildenafil and inhaled iloprost during pregnancy and until several weeks after caesarean section. Case presentation The case presented is of a 29-year-old woman with systemic lupus erythematosus and associated severe pulmonary arterial hypertension. Vasodilator therapy with bosentan and sildenafil, immunosuppressive therapy with prednisone, hydroxychloroquine and azathioprine and oral anticoagulation (phenprocoumon had normalized her right ventricular over right atrial pressure when she was diagnosed in her 5th week of pregnancy. The teratogenic drugs bosentan and phenprocoumon were stopped, the latter replaced by low molecular weight heparin. During the 35th week, a slight increase in pulmonary pressure was found. Therapy with inhaled iloprost was established. A caesarean section was performed in the 37th week and a healthy baby was delivered. The patient remained stable until 11 weeks after delivery, when an increase in right ventricular over right atrial pressure was noted. Bosentan was reintroduced and prednisone and azathioprine doses were increased. The patient has remained stable until the present time. Conclusion Pulmonary arterial hypertension has been considered a contraindication for pregnancy. Novel vasodilator therapy, combined with immunosuppressants in this patient with systemic lupus erythematosus, may "cure" pulmonary arterial hypertension and permit pregnancy with successful outcome. However, postpartum exacerbation of systemic lupus erythematosus and pulmonary arterial hypertension have to be considered.

    Full Text Available Objective: To evaluate the role of bronchoalveolar lavage (BAL in patients with interstitial lung disease associated to antisynthetase syndrome. Methods: We describe 5 patients, anti-Jo1 positive, with interstitial lung disease (lung fibrosis and/or diffusion capacity of CO <80%. Patients were monitored with lung function tests every 6 months, with high-resolution computed tomography (HRCT every 12 months, and with bronchoalveolar lavage (BAL at baseline and in the subsequent follow-up. Patients were treated as follows: a azathioprine with colchicine, or cyclosporine alone b cyclophosphamide when high neutrophil or eosinophil count on BAL was observed. Only low-dose steroids were used for mild muscular or articular involvement. Results: Pulmonary involvement remained stable in all patients at months +24. Lung function remained unchanged compared to the baseline evaluation; HRCT was stable in patients with fibrosis and no progression into fibrosis was observed in patients with ground glass areas at baseline. Bacterial pneumonia occurred in one patient treated with cyclophosphamide and resolved after antibiotic therapy. Conclusions: Clinical manifestations, instrumental tests and BAL may be of value to choice the best immunosuppressive therapy in the single case. An early less aggressive approach (azathioprine with colchicine, or cyclosporine alone may be useful. BAL could be performed when a progression of the lung involvement is demonstrated in the subsequent follow-up. Cyclophosphamide may be a valid alternative treatment in the presence of a neutrophilic or eosinophilic alveolitis. Efficacy and safety of the aforementioned immunosuppressive approach were observed in our series, avoiding prolonged high-dose steroid administration.

    Neurosarcoidosis is a relatively rare complication of sarcoidosis that occurs in approximately 5-15 % of patients. The clinical picture is variable. Clinically, neurosarcoidosis is mostly manifested as lesions of the cranial nerves (50-70 %) and several cranial nerves are typically affected. This is the result of aseptic granulomatous basal meningitis. Intraparenchymal granulomas also occur, frequently affecting basal near-midline structures, such as the hypothalamus and pituitary glands and can lead to encephalopathy. Diagnostics are essentially performed using magnetic resonance imaging (MRI) as it can demonstrate the thickened meninges, which have a high affinity for contrast media but the results are not specific. Particularly in the absence of systemic sarcoidosis, diagnosis can be difficult. Laboratory tests are not very sensitive and specific, which makes neurosarcoidosis a diagnostic challenge. Due to the substantial morbidity of the disease, early and consistent treatment should be initiated. This is usually carried out with corticosteroids supported by immunosuppressant drugs, such as azathioprine and methotrexate. (orig.) [German] Die Neurosarkoidose ist eine seltene Komplikation der Sarkoidose, die bei ca. 5-15 % der Patienten auftritt. Das klinische Bild ist variabel.

    Abstract Rationale: Chronic liver disease is a major cause of morbidity and mortality in patients with HIV. However, autoimmune hepatitis (AIH) in patients with HIV has rarely been reported. Our aim was to evaluate a cohort of patients with HIV and AIH and identify clinical presentations and outcomes. Patient Concerns: Management of autoimmune hepatitis in context of human immunodeficiency virus, long-term outcomes, and safety in setting of underlying immunocompromised state. Diagnoses: Autoimmune Hepatitis, Human Immunodeficiency Virus, Hepatotoxicity, Liver Injury, Liver Transplantation. Interventions: We retrospectively reviewed the charts of patients with HIV and AIH based on histological, serologic, biochemical demographic, and clinical data. Outcomes: Five patients were identified with autoimmune hepatitis; 4 of 5 were women, and all were African or African-American. The age at the time of AIH diagnosis was 46.6 ± 13.4 years. All patients acquired HIV sexually and all had CD4 counts >250 cells/uL (456–1011 cells/uL) and undetectable HIV viral loads at the time of AIH diagnosis. One patient presented with acute liver failure necessitating liver transplantation and developed AIH posttransplantation. At the time of diagnosis, the AST were 350 ± 448 U/L, ALT 247 ± 190 U/L, bilirubin 7 ± 12 mg/dL, and alkaline phosphatase 126 ± 53 U/L. All patients had histologic evidence of AIH on liver biopsies. Patients were successfully treated with prednisone and azathioprine, without a decrease in CD4 <250 cells/uL, infectious complications or significant side effects. Lessons: AIH occurs in patients with well-controlled HIV. In our patient cohort, immunosuppressive therapy with prednisone and azathioprine was safe and effective in inducing remission, without significant complications or development of opportunistic infections.

    Although systemic steroids are highly efficacious in ulcerative colitis (UC),failure to respond to steroids sUll poses an important challenge to the surgeon and physician alike. Even if the life Lime risk of a fulminant UC flare is only 20%, this condition is potentially life threatening and should be managed in hospital. If patients fail 3 to 5 d of intravenous corticosteroids and optimal supportive care, they should be considered for any of three options: intravenous cyclosporine (2 mg/kg for 7 d, and serum level controlled),infliximab (5 mg/kg N,0-2-6 wk) or total colectomy.The choice between these three options is a medicalsurgical decision based on clinical signs, radiological and endoscopic findings and blood analysis (CRP, serum albumin).Between 65 and 85% of patients will initially respond to cyclosporine and avoid colectomy on the short term. Over 5 years only 50% of initial responders avoid colectomy and outcomes are better in patients naive to azathioprine (bridging strategy).The data on infliximab as a medical rescue in fulminant colitis are more limited although the efficacy of this anti tumor necrosis factor (TNF) monoclonal antibody has been demonstrated in a controlled trial. Controlled data on the comparative efficacy of cyclosporine and infliximab are not available at this moment. Both drugs are immunosuppressants and are used in combination with steroids and azathioprine, which infers a risk of serious, even fatal, opportunistic infections. Therefore,patients not responding to these agents within 5-7 d should be considered for colectomy and responders should be closely monitored for infections.

    Objectives To develop recommendations for the management of adult and paediatric lupus nephritis (LN). Methods The available evidence was systematically reviewed using the PubMed database. A modified Delphi method was used to compile questions, elicit expert opinions and reach consensus. Results Immunosuppressive treatment should be guided by renal biopsy, and aiming for complete renal response (proteinuria <0.5 g/24 h with normal or near-normal renal function). Hydroxychloroquine is recommended for all patients with LN. Because of a more favourable efficacy/toxicity ratio, as initial treatment for patients with class III–IVA or A/C (±V) LN according to the International Society of Nephrology/Renal Pathology Society 2003 classification, mycophenolic acid (MPA) or low-dose intravenous cyclophosphamide (CY) in combination with glucocorticoids is recommended. In patients with adverse clinical or histological features, CY can be prescribed at higher doses, while azathioprine is an alternative for milder cases. For pure class V LN with nephrotic-range proteinuria, MPA in combination with oral glucocorticoids is recommended as initial treatment. In patients improving after initial treatment, subsequent immunosuppression with MPA or azathioprine is recommended for at least 3 years; in such cases, initial treatment with MPA should be followed by MPA. For MPA or CY failures, switching to the other agent, or to rituximab, is the suggested course of action. In anticipation of pregnancy, patients should be switched to appropriate medications without reducing the intensity of treatment. There is no evidence to suggest that management of LN should differ in children versus adults. Conclusions Recommendations for the management of LN were developed using an evidence-based approach followed by expert consensus. PMID:22851469

    Full Text Available Abstract Background Eosinophilic gastritis is related to eosinophilic gastroenteritis, varying only in regards to the extent of disease and small bowel involvement. Common symptoms reported are similar to our patient's including: abdominal pain, epigastric pain, anorexia, bloating, weight loss, diarrhea, ankle edema, dysphagia, melaena and postprandial nausea and vomiting. Microscopic features of eosinophilic infiltration usually occur in the lamina propria or submucosa with perivascular aggregates. The disease is likely mediated by eosinophils activated by various cytokines and chemokines. Therapy centers around the use of immunosuppressive agents and dietary therapy if food allergy is a factor. Case presentation The patient is a 31 year old Caucasian female with a past medical history significant for ulcerative colitis. She presented with recurrent bouts of vomiting, abdominal pain and chest discomfort of 11 months duration. The bouts of vomiting had been reoccurring every 7–10 days, with each episode lasting for 1–3 days. This was associated with extreme weakness and cachexia. Gastric biopsies revealed intense eosinophilic infiltration. The patient responded to glucocorticoids and azathioprine. The differential diagnosis and molecular pathogenesis of eosinophilic gastritis as well as the molecular effects of glucocorticoids in eosinophilic disorders are discussed. Conclusions The patient responded to a combination of glucocorticosteroids and azathioprine with decreased eosinophilia and symptoms. It is likely that eosinophil-active cytokines such as interleukin-3 (IL-3, granulocyte macrophage colony stimulating factor (GM-CSF and IL-5 play pivotal roles in this disease. Chemokines such as eotaxin may be involved in eosinophil recruitment. These mediators are downregulated or inhibited by the use of immunosuppressive medications.

    Full Text Available Background: Children have different natural history of Hepatitis B virus (HBV infection. They commonly develop asymptomatic chronic carrier state which is less frequently seen in adults. We describe a rare case of acute on chronic liver failure (ACLF in the course of concurrent autoimmune hepatitis (AIH and HBV infection and replication of HBV following the treatment for autoimmune hepatitis. Case Report: A 15 year old male child presented with jaundice and altered sensorium. Physical examination showed hepatosplenomegaly. The liver function tests were markedly altered. Serology was positive for anti liver kidney microsomal antibody (LKM, hepatitis B surface antigen (HBsAg and immunoglobulin M (IgM anti hepatitis B core antigen (HBc Ag. Liver biopsy showed chronic hepatitis with features of acute exacerbation. Patient was started on treatment with azathioprine and prednisolone for AIH following which clinical and biochmemical improvement was noted. After two years of continued treatment a repeat biopsy performed showed fairly reduced histological activity, but marked replication of the HBV (immunohistochemistry for HBsAg and anti HBcAg showed diffuse cytoplasmic and nuclear positivity respectively. These findings suggest viral replication although the patient was clinically stable. At six months follow-up after the second biopsy and cessation of azathioprine and prednisolone, there were raised liver enzymes and viral load, hence the patient was started on antiviral drug Entecavir to which there was good response and the patient is presently doing well. Conclusion: We describethe rare co occurrence of HBV infection and AIH with marked HBV replication following the treatment for AIH

    Full Text Available Background and Design: Bullous pemphigoid (BP is an autoimmune skin disorder characterized by large, tense blisters of the skin. It occurs mainly in the elderly. The one year mortality associated with bullous pemphigoid ranges from 19% to 41%. We aim to analyse the etiologic factors, demographic features, clinical course and response to treatment in patients with BP. Material and Method: Between January 1999 and January 2008, 31 patients with BP were evaluated retrospectively. We assessed duration of the disease, presence of associated symptoms, clinical findings, drug intake, response to treatment, recurrence rates and also extensive laboratory testing and radiologic evaluations on each patient to clarify a possible underlying malignancy. Results: In a 10-year period, 31 patients with BP, female male ratio was 19/12, ranging in age from 59 to 96 (mean 78.8±8.67 years were evaluated. Duration of the disease was 16.58±18.48 months. Direct immunoflourescence of the perilesional skin showed linear deposition of IgG and C3 along the dermoepidermal junction in 24 patients (77.4%. There was no significant relationship between drug usage and bullous pemphigoid. No malignancy was detected. Medium dosage of prednisolone (50-60 mg/day was the first choice of treatment in 8 patients with a complete response rate in all but two patients died during therapy. Four patients died during hospitalization with unknown reasons before any treatment was started. In 16 cases the initial treatment was prednisolone and azathioprine. The mean follow-up period was 12 months and 11 (35% cases had relapsed. The longest remission was achieved with prednisolone and azathioprine combination. Conclusion: In conclusion, no association was found between BP and drug usage or malignancy. All patients responded well to treatment. Therapy with prednisone maintained with azathiopyrine significantly reduced the recurrences. However, disease-specific mortality is found to be high and

    Serial measurements of serum and urine markers of bone metabolism and of forearm bone density (BMD) by dual photon absorptiometry were performed in 22 patients undergoing renal transplantation in 1986. Patients were randomised to immunosuppression with (1) cyclosporin alone (CsA group, n = 10), (2) cyclosporin for 3 months followed by azathioprine-prednisone (CsA/AzP group, n = 3) or (3) long-term azathioprine-prednisone (LT AzP group, n = 9). As no reduction in bone mineral density (BMD) was noted in the first 6 months, groups 2 and 3 were considered together (AzP group, n = 12). Mean{+-}SEM BMD fell by 19{+-}2% at 36 months (n = 19,m p<0.01), with similar reductions seen in the CsA and AzP groups. At 60 months, BMD of the AzP group was 25{+-}3% below baseline (p<0.01), while the CsA group were only 5{+-}4% belov baseline (p = NS vs baseline, p<0.05 vs AzP group). The degree of reduction in BMD over 5 years correlated with total glucocorticoid dose (r = 0.63, p<0.05), but not with biochemical markers of bone turnover. Serum alkaline phosphatase fell post-transplant in patients treated with AzP, but not in the CsA group. These results demonstrate significant loss of forearm bone mineral with long-term follow-up after renal transplantation, but suggest that patients treated with cyclosporin monotherapy may be at lower risk of this complication.

    The patient was a 13-year-old girl. In August 2000, she presented with a fever, together with diarrhea, vomiting, arthralgia, nasal bleeding and malaise, and was examined by another physician. Because her platelet count was low, and there were positive reactions for anti-nuclear antibodies, anti-DNA antibodies and platelet-associated IgG, idiopathic thrombopenic purpura, and systemic lupus erythematosus (SLE) was suspected. From January 2001, when she caught measles, she reported abdominal pain, and urinalysis indicated urinary protein and occult blood, and the left kidney was found hydronephrotic. At the same time left ureter stenosis and dilatation were demonstrated. Symptoms were disappeared by hydration and treatment with NSAIDs, but 2 months later fever and erythematous patches seen on both cheeks led to the proper diagnosis of SLE, and she was admitted to our hospital. Intravenous pyelography revealed hydronephrosis on left kidney, constriction and dilatation of the left ureter, and intracystic endoscopy showed erythema at the orifice of the left ureter. The pathological examination indicated the presence of vasculitis, and finally lupus cystitis was diagnosed. Intravenous cyclophosphamide (IVCY)-pulse therapy was introduced to a total of 8 times over the period of a year, and maintenance therapy with predonisolone and azathioprin was also used. After completion of the IVCY-pulse therapy, the hydronephrosis and constriction of the ureter were disappeared. No side effects of IVCY-pulses were observed, and the patient is now in remission. We reported a case of childhood SLE complicated with lupus cystitis and successfully treated by IVCY-pulse therapy and maintenance predonisolone and azathioprin.

    Seventeen female patients who underwent orthotopic liver transplantation between June 1973 and June 1987 became pregnant 5 months to 11 years after transplantation. Immunosuppression was maintained with combinations of prednisone, cyclosporine, and azathioprine prior to and during pregnancy. One patient discontinued immunosuppression after knowledge of pregnancy, taking only azathioprine sporadically. Mean age at time of delivery was 26 years. Twelve patients had no alteration in liver function studies; 7 patients demonstrated mild or moderate enzyme elevations prior to delivery, with one case of rejection confirmed by percutaneous liver biopsy. Major problems related to pregnancy were hypertension, anemia, and hyperbilirubinemia. Twenty live births occurred (2 patients had 2 separate pregnancies, one patient had a set of twins); 13 were by caesarian section, 7 by vaginal delivery. Eleven of the 13 caesarian births were premature by gestational age. All vaginal births were term. Toxemia of pregnancy and early rupture of membranes were the principal indications for caesarean section. There were no congenital abnormalities or birth defects and all the children are surviving well. Fifteen of 16 children older than one year all have normal physical and mental development, with one child manifesting immature speech development. Four children are under one year, all with normal milestones thus far. Sixteen of the 17 mothers are alive from 2–18 years after transplantation; the only death was from a lymphoma, almost 4 years after transplantation and 2½ years after delivery. This experience suggests that women undergoing liver transplantation can safely bear children despite an increased risk of premature caesarian births. The effect of chronic immunosuppression of female pediatric patients on their reproductive potential later in adulthood remains to be fully evaluated but the results so far are favorable.

    The cardiovascular and renal pathophysiology associated with chronic renal allograft rejection under triple drug immunosuppressive treatment was studied using a recently developed model (Brown Norway (BN) rats) in a 6-week experiment. Renal transplantation was performed to 10-week-old rats in a rat strain combination of Dark Agouti (DA) --> BN. The right kidney was removed from another group of BN rats (uninephrectomized). A triple drug treatment comprising cyclosporine (10 mg/kg subcutaneously, s.c.), azathioprine (2 mg/kg s.c.) and methylprednisolone (1.6 mg/kg s.c.) was given to each rat daily for 6 weeks. A control group underwent no operations nor drug treatment. After the transplantation, the systolic blood pressure in this group was increased from 116 +/- 2 to 166 +/- 2 mmHg, while in the uninephrectomized group the rise was from 115 +/- 4 to 146 +/- 4 mmHg, and no change was observed in the blood pressures of the control group. The vascular relaxation responses of mesenteric arterial rings in vitro to acetylcholine were inhibited in both the transplantation group and the uninephrectomized group as compared with the control group, but few significant differences were found in the contraction responses to noradrenaline and potassium chloride. Graft histology was examined after 6 weeks, quantified by using the chronic allograft damage index (CADI). Changes specific to a chronic rejection reaction were observed in the allografts (CADI mean 6.0) but no injuries were seen in the rats' own kidneys (CADI mean 1.2). Our findings show that allograft rejection in BN rats after renal transplantation is associated with the development of arterial hypertension. The combination of cyclosporine, methylprednisolone and azathioprine also rises blood pressure in uninephrectomized BN rats. The hypertensive effects of the drug treatment and graft rejection are associated with endothelial dysfunction.

    The purpose of this study was to screen pemphigus vulgaris (PV) (autoimmune bullous skin disease) for the presence of immunoglobulin G against Mycobacterium tuberculosis and Aspergillus fumigatus. The sera of 60 PV patients and 28 controls were screened for the presence of immunoglobulin G against M. tuberculosis and A. fumigatus by enzyme-linked immune-sorbent assay. Forty patients were females and 20 were males. The range of IgG against M. tuberculosis was from 0.9 to 152.6 (median = 2.95) in the patients and was from 0 to 2.2 (median = 1.6) in the controls. Seven (11.7 %) patients and none of the controls exceeded the cut-off value. Four patients were on systemic steroids and azathioprine and three did not receive treatment before. The results showed that PV patients had significantly more IgG against M. tuberculosis than the controls; the p value was 0.006. The range of IgG against A. fumigatus was from 1.3 to 76.3 (median = 4.9) in the patients and was from 1 to 105.3 (median = 5.25) in the controls. Six (10 %) patients and eight (28.6 %) controls exceeded the cut-off value. The six patients were on systemic steroids and azathioprine. No significant difference was detected between PV patients and controls regarding exposure to A. fumigatus; the p value was 0.308. PV patients showed significantly more exposure to the M. tuberculosis than the controls. This suggests that M. tuberculosis may contribute to the pathogenesis of PV.

    Systemic corticosteroids represent the standard treatment for autoimmune pancreatitis with IgG4-associated cholangitis.For steroid-dependent disease,azathioprine has been used for maintenance of remission.Mycophenolate mofetil has been used for transplant immunosuppression and more recently for autoimmune hepatitis; however,there are no case reports to date on the use of mycophenolate mofetil in adult patients with autoimmune pancreatitis.A patient with IgG4-mediated autoimmune pancreatitis and IgG4-associated cholangitis refractory to steroids and intolerant of azathioprine was treated with mycophenolate mofetil,which inhibits de novo guanosine synthesis and blockade of both B and T lymphocyte production.Introduction of mycophenolate mofetil and uptitration to 1000 mg by mouth twice daily over a treatment period of 4 mo was associated with improvement in the patient's energy level and blood glucose control and was not associated with any adverse events.The patient was managed without a biliary stent.However,there was a return of symptoms,jaundice,increase in transaminases,and hyperbilirubinemia when the prednisone dose reached 11 mg per day.In the first report of mycophenolate mofetil use in an adult patient with IgG4-associated autoimmune pancreatitis and IgG4-associated cholangitis,the introduction of mycophenolate mofetil was safe and well-tolerated without adverse events,but it did not enable discontinuation of the steroids.Mycophenolate mofetil and other immunomodulatory therapies should continue to be studied for maintenance of remission in the large subset of patients with refractory or recurrent autoimmune pancreatitis.

    received azathioprine, cyclophosphamide and ciclosporine. Seventeen received oral steroids in addition to immunosuppresive drugs. Four patients combined two immunosupressive drugs to control their disease. In three refractory cases IV immunoglobulin (Ig was administered with good response. From 48 evaluated patients, 39 improved with treatment, eight remained stable and one progressed. In our experience, methotrexate and azathioprine were effective drugs, with low toxicity. Dapsone was useful in mild cases, with frequent adverse effects. IVIg was effective for refractory cases.

    Background Thyroid-associated orbitopathy is commonly associated with Graves' disease with lid retraction, exophthalmos, and periorbital swelling, but rarely with autoimmune thyroiditis or euthyroid state. We reviewed 3 cases from our hospital whose antibodies to anti-receptor of TSH were normal. Methods Case 1: 60 year-old non-diabetic woman with bilateral glaucoma in treatment, recurrent media otitis and euthyroidism, acute onset of painless diplopia, and lid ptosis in the left eye. MRI of orbit showed increased size of the III right cranial pair and high levels of thyroid autoantibodies (Tab) anti-tiroglobulin (ATG) 115.1, anti-thyroid peroxidase (ATPO) 1751 U/mL. She started oral deflazacort 30 mg each 3 days. Sixty days later, complete remission of eye symptoms correlated with lower auto-antibodies level (ATG 19 ATPO 117). Case 2: 10 year-old girl. At age 8, she had diplopia, lid ptosis and limitations of upper gaze in the left eye. The neurological study discarded ocular myasthenia; with thyroid goitier, and hypothyrodism, she started oral levothyroxin. At age 10 with normal IRM Botulinic toxin was injected, without change. High levels of Tab were found, ATG 2723, ATPO 10.7. She started oral deflazacort 30 mg each 3 days, azathioprin 100 mg, daily. Actually, Tab levels are almost normal, but she remains with ocular alterations. Case 3: 56 year-old woman, Grave´s disease with exophtalmos in 1990, treated with I131 and immunosupression, with good outcome; obesity, hypertension and bilateral glaucoma in treatment. She suddenly presented diplopia and IV pair paresia of the right eye. A year later, ATb were found slightly elevated, ATG 100 years ATPO 227; despite prednisone 50 mg, each 3 days and azathioprin 150 mg/daily treatment, a surgical procedure was required for relieve the ocular symptoms. Results We found only 3 cases previously reported with this type of eye thyroid disease. Is important to note that awareness of this atypical form of orbitopathy

    Full Text Available Abstract Background Oral thiopurines are effective and widely used in treatment of inflammatory bowel disease (IBD in humans, although their use is limited due the development of adverse events. Here, we examine the efficacy and toxicity of oral treatment with 6-tioguanine (6-TG and azathioprine (AZA in a murine model of IBD. Methods We induced acute or chronic colitis in BALB/c mice by one or four cycles of 3% dextran sulphate sodium (DSS, respectively. Mice were treated by daily gavages of various dosages of 6-tioguanine, azathioprine, or by phosphate buffered saline (PBS starting the first day of DSS or after two cycles of DSS, respectively. We monitored the efficacy and toxicity by measuring the weight change and serum alanine aminotransferase (ALT activity and by disease severity and histology, at the end of the experiment. Moreover, we measured cytokine production after colon fragment cultivation by enzyme-linked immunoabsorbent assay and numbers of apoptotic cells in the spleen by flow cytometry. Results 6-TG is effective in the treatment of acute DSS-induced colitis in a dose-dependent manner and 40 μg of 6-TG is significantly more effective in the treatment of acute colitis than both AZA and PBS. This effect is accompanied by decrease of IL-6 and IFN-γ production in colon. We did not observe histological abnormalities in liver samples from control (PBS or 6-TG treated mice. However, liver samples from most mice treated with AZA showed mild, yet distinct signs of hepatotoxicity. In chronic colitis, all thiopurine derivatives improved colitis, 20 μg of 6-TG per dose was superior. High doses of 6-TG led to significant weight loss at the end of the therapy, but none of the thiopurine derivatives increased levels of serum ALT. Both thiopurine derivatives reduced the proportion of apoptotic T helper cells, but a high production of both IL-6 and TGF-β was observed only in colon of AZA-treated mice. Conclusions Use of 6-TG in the treatment

    Full Text Available Kidney transplantation offers best hope to women with end-stage renal disease who wish to become pregnant. Pregnancy in a kidney transplant recipient continues to remain challenging due to side effects of immunosuppressive medication, risk of deterioration of allograft function, risk of adverse maternal complications of preeclampsia and hypertension, and risk of adverse fetal outcomes of premature birth, low birth weight, and small for gestational age infants. The factors associated with poor pregnancy outcomes include presence of hypertension, serum creatinine greater than 1.4 mg/dL, and proteinuria. The recommended maintenance immunosuppression in pregnant women is calcineurin inhibitors (tacrolimus/cyclosporine, azathioprine, and low dose prednisone; and it is considered safe. Sirolimus and mycophenolate mofetil should be stopped 6 weeks prior to conception. The optimal time to conception continues to remain an area of contention. It is important that counseling for childbearing should start as early as prior to getting a kidney transplant and should be done at every clinic visit after transplant. Breast-feeding is not contraindicated and should not be discouraged. This review will help the physicians in medical optimization and counseling of renal transplant recipients of childbearing age.

    SUMMARY Purpose Oral Lichen Planus (OLP) is a chronic inflammatory disease of skin and mucous membranes. Approximately 20% of women with oral lichen planus develops lesions in the genital mucosa. In 1982, Pelisse described a special form of lichen planus (LP), which consists of a triad of symptoms: vulval, vaginal and gingival (VVG)-LP lesions. Aim of the present report is to report two new cases and review the international literature. Material and methods Two cases of VVG-LP are reported and a review of recent literature is performed. Results The onset of erosive or ulcerative mouth lesions may precede or follow by months or even years the onset of vulvovaginal lesions. Vaginal agglutination is associated with the postmenopausal state in conjunction with a dermatologic condition. Intra-lesional corticosteroids have a role in localized chronic ulceration, while systemic therapies such as corticosteroids, azathioprine, mycophenolate mofetil, hydroxychloroquine, ciclosporin, methotrexate, retinoids, thalidomide and photo chemotherapy have been used in more severe cases with varying success. Conclusions VVG-LP is rather a rare condition and has been documented in the literature mainly in the form of case reports. Lack of a precise diagnostic criteria of VVG-LP depends on the specialists.

    Noonan Syndrome (NS) is characterized by short stature, typical facial dysmorphology and congenital heart defects. The incidence of NS is estimated to be between 1:1000 and 1:2500 live births. The syndrome is transmitted as an autosomal dominant trait. In approximately 50% of cases, the disease is caused by missense mutations in the PTPN11 gene on chromosome 12, resulting in a gain of function of the non-receptor protein tyrosine phosphatase SHP-2 protein. Autoimmune Hepatitis (AIH) is a cryptogenic, chronic and progressive necroinflammatory liver disease. Common features of AIH are hypergammaglobulinemia (IgG), presence of circulating autoantibodies, histological picture of interface hepatitis and response to immunosuppressant drugs. Conventional treatment with Prednisone and Azathioprine is effective in most patients. We describe the case of a 6 years-old girl with Noonan Syndrome and Autoimmune Hepatitis type 1. Molecular analysis of PTPN11 gene showed heterozygous mutation c.923A>G (Asn308Ser) in exon 8. Though association between NS and autoimmune disorders is known, this is the second case of association between Noonan Syndrome and Autoimmune Hepatitis type 1 described in literature. In the management of NS, an accurate clinical evaluation would be recommended. When there is a clinical suspicion of autoimmune phenomena, appropriate laboratory tests should be performed with the aim of clarifying whether the immune system is involved in NS. We think that autoimmunity represents a characteristic of NS, even if the etiopathogenesis is still unknown.

    Blau syndrome (BS) and early onset sarcoidosis (EOS) are, respectively, the familial and sporadic forms of the pediatric granulomatous autoinflammatory disease, which belong to the group of monogenic autoinflammatory syndromes. Both of these conditions are caused by mutations in the NOD2 gene, which encodes the cytosolic NOD2 protein, one of the pivotal molecules in the regulation of innate immunity, primarily expressed in the antigen-presenting cells. Clinical onset of BS and EOS is usually in the first years of life with noncaseating epithelioid granulomas mainly affecting joints, skin, and uveal tract, variably associated with heterogeneous systemic features. The dividing line between autoinflammatory and autoimmune mechanisms is probably not so clear-cut, and the relationship existing between BS or EOS and autoimmune phenomena remains unclear. There is no established therapy for the management of BS and EOS, and the main treatment aim is to prevent ocular manifestations entailing the risk of potential blindness and to avoid joint deformities. Nonsteroidal anti-inflammatory drugs, corticosteroids and immunosuppressive drugs, such as methotrexate or azathioprine, may be helpful; when patients are unresponsive to the combination of corticosteroids and immunosuppressant agents, the tumor necrosis factor-α inhibitor infliximab should be considered. Data on anti-interleukin-1 inhibition with anakinra and canakinumab is still limited and further corroboration is required. The aim of this paper is to describe BS and EOS, focusing on their genetic, clinical, and therapeutic issues, with the ultimate goal of increasing clinicians' awareness of both of these rare but serious disorders.

    Chronic allograft damage, defined by interstitial fibrosis and tubular atrophy (IF/TA), is a leading cause of allograft failure. Few effective therapeutic options are available to prevent the progression of IF/TA. We applied a meta-analysis approach on IF/TA molecular datasets in Gene Expression Omnibus to identify a robust 85-gene signature, which was used for computational drug repurposing analysis. Among the top ranked compounds predicted to be therapeutic for IF/TA were azathioprine, a drug to prevent acute rejection in renal transplantation, and kaempferol and esculetin, two drugs not previously described to have efficacy for IF/TA. We experimentally validated the anti-fibrosis effects of kaempferol and esculetin using renal tubular cells in vitro and in vivo in a mouse Unilateral Ureteric Obstruction (UUO) model. Kaempferol significantly attenuated TGF-β1-mediated profibrotic pathways in vitro and in vivo, while esculetin significantly inhibited Wnt/β-catenin pathway in vitro and in vivo. Histology confirmed significantly abrogated fibrosis by kaempferol and esculetin in vivo. We developed an integrative computational framework to identify kaempferol and esculetin as putatively novel therapies for IF/TA and provided experimental evidence for their therapeutic activities in vitro and in vivo using preclinical models. The findings suggest that both drugs might serve as therapeutic options for IF/TA. PMID:28051114

    In the last few decades a number of small, often largely unrecognized steps have fundamentally changed the management of systemic lupus erythematosus (SLE). The current goal is to stop all disease activity without long-term use of more than 5 mg prednisolone per day. Remission, i.e. absence of activity in the SLE activity score of choice, is the defined target in the treat to target approach. The essential basic measures include life-long hydroxychloroquine as well as protection from sunlight (UV) and vitamin D substitution. Patients suffering from SLE need more vaccinations than the healthy population and control of risk factors for atherosclerosis is critical for long-term survival. Methotrexate is on par with azathioprine. If disease activity cannot be controlled in this way, belimumab is an approved therapeutic option. Cyclophosphamide is still used but only in life-threatening situations, such as lupus nephritis or central nervous system (CNS) vasculitis and in drastically reduced doses. Alternatively, off-label mycophenolate mofetil (MMF) can be used particularly for lupus nephritis and off-label rituximab in refractory disease courses. Numerous novel approaches are being tested in controlled trials and it is hoped that new drugs will be available for SLE patients within a few years.

    The objectives of the study were to examine the initial, first-year anti-rheumatic outpatient therapy in patients with incident SLE, as well as the concomitant use of drugs for certain comorbidities, compared to the use in the general population. The Finnish nationwide register data on special reimbursements for medication costs was screened to identify the inception cohort of 566 adult SLE patients (87% females, mean age 46.5 ± 15.9 years) over the years 2000-2007. The patients were linked to the national Drug Purchase Register. Of those, 90% had purchased at least once some disease-modifying anti-rheumatic drugs (DMARDs) during the first year. Hydroxychloroquine was the most common (76%), followed by azathioprine (15%) and methotrexate (13%). With the exception of increase in mycophenolate mofetil, the proportions remained stable over the whole study period 2000-2007. Drugs for cardiovascular diseases, dyslipidemia, diabetes mellitus, hypothyroidism and obstructive pulmonary disease were more frequently purchased than in the sex- and age-adjusted population, with rate ratios ranging from 1.6 to 7.8. Over the years 2000-2007, almost all the patients with incident SLE in Finland started with a DMARD. Higher percentages of SLE patients were on medication for several common chronic diseases than in the population as a whole.

    Full Text Available Introduction. Systemic lupus erythematosus (SLE is a chronic immunological disease causing a significant morbidity and mortality in younger women and involving several organs and systems, most often the kidneys, being consequently the incidence of lupus nephritis (LN about 60%. Case report. We reported a 57 year-old patient with the diagnosed SLE in 1995. Pathohistological analysis of kidney biopsy revealed LN type V. The patient was treated with corticosteroid pulses and azathioprine during one year. A remission was achieved and maintained with prednisone, 15 mg daily. Nephrotic relapse was diagnosed in 2006 and the second kidney biopsy revealed recent kidney infarction due to extensive vasculitis. Soon, a cerebrovascul insult developed and CT-scan revealed endocranial infarctus. The patient was treated with corticosteroids and cyclophosphamide pulses (totally VI monthly pulses, and also with low-molecular heparine, anticoagulants and salicylates because of the right leg phlebothrombosis. After the pulses, the patient was adviced to take prednisone 20 mg daily and azothioprine 100 mg daily, and 6 months later mycophenolate mofetil because of persistent active serological immunological findings (ANA 1 : 320 and nephrotic syndrome. Mycophenolate mofetil was efficient in inducing and maintaining remission of nephrotic syndrome. Conclusion. The aim of LN treatment is to achieve and maintain remission, improve patients’ outcome, reduce the toxicity of immunosuppressive drugs and the incidence of relapses. Mycophenolate mofetil was shown to be efficient in inducing and maintaining remission of nephrotic syndrome in the frame of LN.

    There have been few changes over the last 50 years in the treatment of Systemic lupus erythematosus (SLE), using non-specific anti-inflammatory agents such as: nonsteroidal anti-inflammatory drugs along with the immune cell modulating agent hydroxychloroquine for mild disease, and broad spectrum immunosuppressants plus antiinflammatories such as corticosteroids, azathioprine, cyclophosphamide, or mycophenolate during flares or severe disease with organ involvement. In some patients, the response is inadequate and side effects appear from mild unpleasant up to severe toxicity. Drug metabolism and clearance may be severely compromised. Therefore, it is a priority to develop better treatments with fewer adverse events that can be used at different stages of disease activity. In recent years, a member of the tumor necrosis factor (TNF) family, soluble human B Lymphocyte Stimulator protein (BLyS), also referred to as B-cell activating factor (BAFF) and TNFSF13B has been studied extensively. This protein is synthesized by myeloid cell lines, specifically interacts with B lymphocytes and increases their life-span. BlyS plays a key role in the selection, maturation and survival of B cells and it has a significant role in the pathogenesis of SLE. In this review, we analyzed the role of BLyS as a diagnostic/prognostic marker and/or therapeutic target for lupus patients, and the different clinical studies published using belimumab.

    Lupus erythematosus (LE) is a multifactorial autoimmune disease with clinical manifestations of differing severity which may present with skin manifestations as primary sign of the disease (cutaneous lupus erythematosus, CLE) or as part of a disease spectrum (systemic lupus erythematosus, SLE). To date, no drugs are approved specifically for the treatment of CLE and only single agents have been applied in randomized controlled trials. Therefore, topical and systemic agents are used "off-label", primarily based on open-label studies, case series, retrospective analyses, and expert opinions. In contrast, several agents, such as hydroxychloroquine, chloroquine, cyclophosphamide, azathioprine, and belimumab, are approved for the treatment of SLE. Recent approaches in the understanding of the molecular pathogenesis of LE enabled the development of further new agents, which target molecules such as interleukin 6 (IL-6) and interferon (IFN). Only single trials, however, applied these new agents in patients with cutaneous involvement of the disease and/or included endpoints which evaluated the efficacy of these agents on skin manifestations. This article provides an updated review on new and recent approaches in the treatment of CLE.

    A 74-year-old gentleman was admitted to the regional neurosciences center with encephalopathy, myokymia, and dysautonomia. Chest imaging had previously identified an incidental mass in the anterior mediastinum, consistent with a primary thymic tumor. Antivoltage-gated potassium channel (anti-VGKC) antibodies were positive (titer 1273 pmol/L) and he was hypokalemic. Electromyogram and nerve conduction studies were in keeping with peripheral nerve hyperexcitability syndrome, and an electroencephalogram was consistent with encephalopathy. A diagnosis of Morvan syndrome was made, for which he was initially treated with high-dose steroids, followed by a 5-day course of intravenous immunoglobulin (IVIG) therapy. He also underwent thymectomy, followed by a postexcision flare of his symptoms requiring intensive care management. Further steroids, plasmapheresis, and IVIG achieved stabilization of his clinical condition, enabling transfer for inpatient neurorehabilitation. He was commenced on azathioprine and a prolonged oral steroid taper. A subsequent presumed incipient relapse responded well to further IVIG treatment. This case report documents a thymoma-associated presentation of anti-VGKC-positive Morvan syndrome supplemented by patient and carer narrative and video, both of which provide valuable further insights into this rare disorder. There are a limited number of publications surrounding this rare condition available in the English literature. This, combined with the heterogenous presentation, association with underlying malignancy, response to treatment, and prognosis, provides a diagnostic challenge. However, the association with anti-VGKC antibody-associated complexes and 2 recent case series have provided some scope for both accurate diagnosis and management.

    Full Text Available Background: Pemphigus, bullous pemphigoid, and epidermolysis bullosa acquisita are autoimmune diseases of skin associated with considerable morbidity and sometimes mortality. There is no cure for these diseases. Aims: To summarize evidence-based treatments for these diseases by performing a systematic review. Methods: The research protocol included the following steps: identification of databases to be searched, defining search strategy, searching the databases for references, first-stage screening of the abstracts, second-stage screening of full texts of articles identified after the first-stage screening, data extraction from the identified articles after second-stage screening, quality appraisal of the studies using the Delphi list, and summarizing the findings. Results: No randomized controlled trials of interventions in pemphigus vegetans, pemphigus erythematosus, and epidermolysis bullosa acquisita could be found. After the second-stage screening, 12 randomized controlled trials were analyzed, which included patients with pemphigus vulgaris or pemphigus vulgaris and pemphigus foliaceus, and 7 which included patients with bullous pemphigoid. Conclusions: Number of high-quality randomized controlled trials conducted on pemphigus and bullous pemphigoid is small. Oral corticosteroid along with a steroid-sparing agent appears to be the most effective treatment for pemphigus. Azathioprine may be most effective as a steroid-sparing agent. Topical corticosteroid therapy (as studied is effective for bullous pemphigoid and appears to be superior to oral corticosteroid for extensive disease. Some suggestions about future research are made.

  19. Interstitial lung disease in patients with rheumatoid arthritis: spontaneous and drug induced.

    2014-03-01

    Rheumatoid arthritis (RA) is an inflammatory autoimmune disease characterized by the destruction of articular joint structures. RA is a systemic condition that often affects multiple organs, including the heart, lungs, and kidneys. Pulmonary complications of RA are relatively common and include pleural effusion, rheumatoid nodules, bronchiectasis, obliterative bronchiolitis, and opportunistic infections. Interstitial lung disease (ILD) is a common occurrence in patients with RA, and can range in severity from an asymptomatic incidental finding to a rapidly progressing life-threatening event. Usual interstitial pneumonia and non-specific interstitial pneumonia are the two most common patterns, though others have been reported. Various disease-modifying anti-rheumatic drugs-in particular, methotrexate and the tumor necrosis factor-alpha inhibitors-have been associated with RA-ILD in numerous case reports and case series, though it is often difficult to distinguish association from causality. Treatment for RA-ILD typically involves the use of high-dose corticosteroids, often in conjunction with alternative immunosuppressant agents such as azathioprine or mycophenolate mofetil, and outcomes vary widely depending on the initial pattern of lung disease. Additional research into the mechanisms driving RA-ILD is needed to guide future therapy.

  20. Teratogenesis and immunosuppressive treatment.

    Despite the potential risks to the mother and fetus caused by immunosuppressive drugs, uneventful pregnancies are now frequent among transplant recipients. Although there is no apparent increase in the type or incidence of malformations in the newborns or evidence of graft dysfunction, pregnancy-related complications, including premature termination and low birth weight, may be more frequent. To prevent graft rejection due to the increased immunologic reactivity of the transplant recipient during pregnancy, it is reasonable to wait 2 years after transplantation before conception, to have stable graft function and to be on low drug doses for maintenance immunosuppression. Among the immunosuppressive agents, corticosteroids may induce a number of treatment-related complications, including diabetes and osteoporosis; however, the incidence of fetal malformations during corticosteroid treatment is about 3.5%, a value close to that of the general population. Among immunosuppressive antibodies, no evidence of developmental toxicity has been demonstrated with basiliximab. On the contrary, some concerns have been raised about azathioprine, since its use has been associated with fetal abnormalities in animals; however, clinical data so far have indicated only a small teratogenic risk. Therefore, immunosuppressive therapy with selected drugs and antibodies does not apparently increase the risk of birth defects and may be continued in pregnancy. Finally, although breast-feeding is not recommended, because of drug transfer into maternal milk, the available clinical data do not support this limitation because of the low amount of drug absorbed by the infant and the absence of clinical toxicity in published case reports.

    Full Text Available Myasthenia gravis (MG in childhood is rare comprising 10 to 20 % of all myasthenic patients. We studied 18 patients with MG whose first symptoms started from 1 to 12 years of age, followed at the Department of Neurology of the UNIFESP-EPM, from January 1983 to August 1997. There were 10 girls and 8 boys (1.2:1. Eleven patients (61% presented moderate or severe generalized disease and 4 (22% had at least one myasthenic crisis. EMG with supramaximal repetitive nerve stimulation was diagnostic in 8 (47% out of 17 patients, and chest CT was normal in 14 patients. Seropositivity to acetylcholine receptor antibodies was found in 81.6% (9 out of 11 tested and the levels had no relation to clinical severity. Nine out of 16 patients (56% worsened with pyridostigmine alone and were treated with prednisone. Four out of those nine continued worsening despite steroids and were subjected to thymectomy (all showed thymic lymphoid follicular hyperplasia. Three patients (75% improved markedly after thymectomy and one (25% worsened, eventually getting better with intravenous immunoglobulin and oral azathioprine. MG treatment, using all resources available, has to be individualized for each child.

    Full Text Available "nFamilial Mediterranean fever (FMF is a relatively rare disorder, characterized by recurrent self-limited attacks of fever and polyserositis. Diagnosis is made by clinical features, gene identification on chromosome 16 and clinical response to specific treatment. Different types of vasculitis have been reported in FMF. Henoch-Schönlein purpura (HSP is one of them, usually with a benign clinical course. Repeated attacks of HSP have been rarely reported in FMF. This is the report of a 7-year-old girl who presented initially with recurrent fever and abdominal pain. After the primary diagnosis of FMF and appropriate treatment, she experienced two documented repeated attacks of HSP with severe renal involvement (crescentric glomerulonephritis and protracted abdominal pain in the second one. Glomerulonephritis was controlled by methyl-prednisolone pulse therapy plus oral corticosteroid and azathioprine, but abdominal pain was resistant to steroids and revealed completely by intravenous immunoglobuline (IVIg administration. In conclusion, it is suggested to consider the recurrence of HSP in cases with FMF to prevent irreversible renal complications. IVIg seems to be a good choice for the management of intractable abdominal pain of HSP.

    Full Text Available Neuromyelitis optica (NMO is an inflammatory disease of the central nervous system characterized by severe optic neuritis and transverse myelitis, usually with a relapsing course. Aquaporin-4 antibody is positive in a high percentage of NMO patients and it is directed against this water channel richly expressed on foot processes of astrocytes. Due to the severity of NMO attacks and the high risk for disability, treatment should be instituted as soon as the diagnosis is confirmed. There is increasing evidence that NMO patients respond differently from patients with multiple sclerosis (MS, and, therefore, treatments for MS may not be suitable for NMO. Acute NMO attacks usually are treated with high dose intravenous corticosteroid pulse and plasmapheresis. Maintenance therapy is also required to avoid further attacks and it is based on low-dose oral corticosteroids and non-specific immunosuppressant drugs, like azathioprine and mycophenolate mofetil. New therapy strategies using monoclonal antibodies like rituximab have been tested in NMO, with positive results in open label studies. However, there is no controlled randomized trial to confirm the safety and efficacy for the drugs currently used in NMO.

    Patients on thiopurine therapy need frequent monitoring to prevent drug adverse events. To describe the structure and main results of a nurse-driven outpatient clinic (NDOC) program for the follow-up of patients receiving treatment with thiopurine immunosuppressants, we retrospectively reviewed patients' clinical charts on thiopurine drugs, azathioprine (AZA), and 6-mercaptopurine. We evaluated the efficacy of the NDOC by comparing the number of physician visits and the adequacy of laboratory controls for each patient before and after inclusion in the program. From January 2006 to December 2008, 179 patients were included. Of these, 102 had received thiopurines for at least 1 year before the start of the NDOC. Mean age was 42 ± 15 years; 83 were female. In all, 137 of the 179 patients (76%) had Crohn disease. AZA was the most frequent drug used (97%). Mean time of follow-up was 2.03 ± 0.9 years. Implementation of this program decreased the number of physician visits per year-from 4.6 ± 1.9 to 2.4 ± 1.3 (p < .001)-and the number of periods longer than 4 months without laboratory control (from 68% to 45%; p = .01). Leucopenia episodes and complications did not differ significantly before and after the start of the NDOC. Nurse-driven follow-up of these patients reduces physician visits while improving tightness of the follow-up.

    Dermatomyositis is an idiopathic inflammatory myopathy that cause skin and muscle complications. The ethiology is not understood well yet. Released cytokines including interferon and interleukins are suggested to make inflammatory responses in the skin or muscle. Muscle weakness and skin lesions including heliotrope rash, shawl sign and Gottron's papules are the most common symptoms. A biopsy (muscle or skin) is always the most reliable method for diagnosis. Corticosteroids in association with immunosuppressive agents are used as standard treatment. The patient was a 30 years old woman who got involved with dermatomyositis for 10 years. She has been under therapy with Methotrexate, Prednisolon and Azathioprine until she came to us suffering from progressive skin lesions. Experiments and examinations were normal except the lesions and detected lipoatrophy. Because of immune cells infiltration and observations necrotizing vasculitis was diagnosed. After three month of high dose prednisolon and intravenous cyclophosphamide therapy the lesions vanished remarkable. True and immediate diagnosis gives physicians the chance not only to assess the best treatment but have adequate time to apply the procedure. However shortening the therapy and diminishing morbidity of the disease need more investigations and efforts.

    Sjögren syndrome affecting the major cerebral arteries is rare, and an optimal therapeutic strategy to counteract such a lesion has not yet been established. We herein report a case of a 39-year-old woman with a history of primary Sjögren syndrome, which had previously been treated with immunosuppressive therapy, manifesting with a crescendo transient ischemic attack because of left middle cerebral artery stenosis. Despite the administration of high doses of prednisolone and azathioprine for active Sjögren syndrome, the frequency of crescendo transient ischemic attacks increased with the progression of stenosis and magnetic resonance imaging showed the development of subacute cerebral infarction. Single-photon emission computed tomography with N-isopropyl[(123)I]-p-iodoamphetamine revealed apparent hemodynamic compromise in the affected cerebral hemisphere. In light of the increased risk of further progression of cerebral infarction, we decided to perform surgical revascularization in spite of her active inflammatory condition. The patient underwent extracranial-intracranial bypass without complications and was treated with intensive immunosuppressive therapy during the perioperative period. Based on our findings, we recommend surgical revascularization for occlusive cerebrovascular disease with hemodynamic compromise in combination with intensive immunosuppressive therapy, even in the active inflammatory state of autoimmune diseases, if ischemic symptoms are medically uncontrollable.

    Because toxicity with the use of 3000 centiGray (cGy) of total lymphoid irradiation (TLI) was observed in an earlier study, 2000-cGy treatments were delivered in a 2-portal format to 7 patients and in a modified 3-portal fashion to 6 patients, as part of a randomized, investigator-blinded trial of TLI treatment for refractory rheumatoid arthritis. Analysis of combined data from the 13 patients revealed statistically significant improvement in 5 clinical indicators of disease activity at the end of TLI and 6 and 12 months later, accompanied by T4-specific immunosuppression. Management considerations resulted in the introduction of prednisone therapy in 5 patients, methotrexate in 4, and azathioprine in 1 during the interval of 8-12 months post-TLI. Herpes zoster occurred in 5 patients prior to the initiation of this additional therapy. These data indicate that, in patients with rheumatoid arthritis, a TLI dose of 2000 cGy is sufficient to produce measurable benefit that lasts for 6 months, and that the improvement can be maintained at 12 months by the use of prednisone and methotrexate.

    The three major immune disorders of the liver are autoimmune hepatitis (AIH),primary biliary cirrhosis (PBC) and primary sclerosing cholangitis (PSC).Variant forms of these diseases are generally called overlap syndromes,although there has been no standardised definition.Patients with overlap syndromes present with both hepatitic and cholestatic serum liver tests and have histological features of AIH and PBC or PSC.The AIH-PBC overlap syndrome is the most common form,affecting almost 10% of adults with AIH or PBC.Single cases of AIH and autoimmune cholangitis (AMA-negative PBC) overlap syndrome have also been reported.The AIH-PSC overlap syndrome is predominantly found in children,adolescents and young adults with AIH or PSC.Interestingly,transitions from one autoimmune to another have also been reported in a minority of patients,especially transitions from PBC to AIH-PBC overlap syndrome.Overlap syndromes show a progressive course towards liver cirrhosis and liver failure without treatment.Therapy for overlap syndromes is empiric,since controlled trials are not available in these rare disorders.Anticholestatic therapy with ursodeoxycholic acid is usually combined with immunosuppressive therapy with corticosteroids and/or azathioprine in both AIH-PBC and AIH-PSC overlap syndromes.In end-stage disease,liver transplantation is the treatment of choice.

    Systemic lupus erythematosus (SLE) is a complex autoimmune disease with variable clinical manifestations. While the clearest guidelines for the treatment of SLE exist in the context of lupus nephritis, patients with other lupus manifestations such as neuropsychiatric, hematologic, musculoskeletal, and severe cutaneous lupus frequently require immunosuppression and/or biologic therapy. Conventional immunosuppressive agents such as mycophenolate mofetil, azathioprine, and cyclophosphamide are widely used in the management of SLE with current more rationalized treatment regimens optimizing the use of these agents while minimizing potential toxicity. The advent of biologic therapies has advanced the treatment of SLE particularly in patients with refractory disease. The CD20 monoclonal antibody rituximab and the anti-BLyS agent belimumab are now widely in use in clinical practice. Several other biologic agents are in ongoing clinical trials. While immunosuppressive and biologic agents are the foundation of inflammatory disease control in SLE, the importance of managing comorbidities such as cardiovascular risk factors, bone health, and minimizing susceptibility to infection should not be neglected.

    The concurrence of inflammatory bowel disease with systemic lupus erythematosus (SLE) is rare. The concomitant diagnosis of Crohn's disease and SLE is even more rare. The patient, a 40-year-old woman, was admitted to our hospital because of relapsing episodes of abdominal pain, diarrheas upper and lower extremities arthralgias, Raynaud's phenomenon with positive antinuclear antibodies, and fever for the last 2 years. The patient was diagnosed elsewhere with SLE and treated with hydroxychloroquine. Her medical history also included tonsillectomy and total hip replacement after a car accident. Family history was unremarkable. Physical examination was unremarkable except of very mild pain at lower left abdominal quadrant. Laboratory tests showed erythrocyte sedimentation rate at 32 mm/h, C-reactive protein at 36 mg/dl, positive rheumatoid factor, and increased C3, C4, positive antinuclear antibodies with the presence of anti-Sm and anti-RNP antibodies. Ileocolonoscopy revealed colonic inflammation with ulcers and pseudopolyps. Subsequent biopsies were diagnostic of Crohn's disease. Patient was diagnosed with Crohn's colitis concomitant to systemic lupus erythematosus and was started on therapy with azathioprine 2 mg/Kg, methylprednisolone 16 mg/d with slow tapering, mesalazine 1.5 g/day, and hydroxychloroquine. Patient is in excellent health status on the six-month follow-up.

    Pyomyositis is a pyogenic infection of skeletal muscle that arises from hematogenous spread and usually presents with localized abscess. This muscle infection has been rarely reported in adult-onset systemic lupus erythematous and, to the best of our knowledge, has not been diagnosed in pediatric lupus population. Among our childhood-onset systemic lupus erythematous population, including 289 patients, one presented pyomyositis. This patient was diagnosed with childhood-onset systemic lupus erythematous at the age of 10 years-old. After six years, while being treated with prednisone, azathioprine and hydroxychloroquine, she was hospitalized due to a 30-day history of insidious pain in the left thigh and no apparent trauma or fever were reported. Her physical examination showed muscle tenderness and woody induration. Laboratory tests revealed anemia, increased acute phase reactants and normal muscle enzymes. Computer tomography of the left thigh showed collection on the middle third of the vastus intermedius, suggesting purulent stage of pyomyositis. Treatment with broad-spectrum antibiotic was initiated, leading to a complete clinical resolution. In conclusion, we described the first case of pyomyositis during childhood in pediatric lupus population. This report reinforces that the presence of localized muscle pain in immunocompromised patients, even without elevation of muscle enzymes, should raise the suspicion of pyomyositis. A prompt antibiotic therapy is strongly recommended.

    Full Text Available Elisabeth Lippert, Martina Müller, Claudia Ott University Hospital Regensburg, Department of Internal Medicine I, Regensburg, Germany Abstract: Ulcerative colitis (UC is a chronic inflammation mainly affecting the colon mucosa. It predominantly occurs in younger patients. Until recently, the main goals in the treatment of UC were to temper the symptoms, such as diarrhea, pain, and weight loss, by using mesalazine and steroids. With newer medications, such as immunomodulators (thiopurines and the biologics providing blockade of tumor necrosis factor (TNF, the goals of the therapy in UC have changed to long-term remission and mucosal healing. The first available anti-TNF therapy in UC included infusion therapy with infliximab every few weeks. In 2012, subcutaneously administered adalimumab gained approval for the treatment of UC in Germany. In patients with a mild disease, therapy with mesalazine, orally or topically, can be sufficient. In patients with moderate to severe disease, therapy with azathioprine or anti-TNF is often required to reach disease control; however, this is only efficient in about two-thirds of patients. Some patients either show no response or a lost response while on treatment. So, further medical options are warranted in the treatment of UC. With golimumab, a new approach in the treatment of mild to moderate UC recently became available in Germany and is a promising new option in the therapy regimen for patients with UC.

    2015-03-01

    Full Text Available Pityriasis rubra pilaris (PRP is an exceptionally rare, chronic inflammatory dermatosis of unknown etiology. Patients classically present with small, follicular keratosis and salmon-colored plaques that begin at the head and neck and slowly progress to widespread erythroderma including the palms and soles. It is difficult to distinguish PRP from other inflammatory dermatoses; however, features that help aid in the diagnosis include ‘islands' of spared skin, orangish hue and typical findings on biopsy. There are no specific guidelines on therapy and treatment options include corticosteroids, vitamin D analogs, retinoids, methotrexate, cyclosporine, azathioprine and tumor necrosis factor alpha antagonists. Unfortunately options are limited for patients when these drugs do not work. We report a case of chronic PRP, refractory to conventional treatment, successfully treated with ustekinumab monotherapy. The patient was treated with 90 mg subcutaneous ustekinumab injections and began to show improvement within only 8 weeks. Long-term control of the disease has been attained without any significant side effects. We report this case to show that ustekinumab can be used as an alternative treatment method for patients with chronic, unremitting PRP. Treatment response is remarkably rapid and the infrequent dosing leads to patient compliance and a significantly improved quality of life.

    2013-09-01

    Full Text Available We report a case of a 43-year-old female who presented with right ear fullness and otorrhea. She was initially diagnosed with mastoiditis that was not responsive to multiple courses of antibiotics and steroids. She was then diagnosed with refractory inflammatory pseudotumor, and subsequent treatments included several mastoidectomies, further steroids, and radiation therapy. The patient went on to develop mastoiditis on the contralateral side as well as central nervous system involvement with headaches and right-sided facial paresthesias. Reexamination of the mastoid tissue revealed a significantly increased number of IgG4-positive cells, suggesting a diagnosis of IgG4-related disease. The patient improved clinically and radiographically with rituximab and was able to taper off azathioprine and prednisone. IgG4-related disease should be considered in patients with otologic symptoms and be on the differential diagnosis in patients with inflammatory pseudotumor. Staining for IgG and IgG4 is essential to ensure a prompt diagnosis and treatment.

    2016-03-01

    Full Text Available Progressive multifocal leukoencephalopathy (PML caused by reactivation of the JC virus (JCV, a human polyomavirus, occurs in autoimmune disorders, most frequently in systemic lupus erythematosus (SLE. We describe a HIV-negative 34-year-old female with SLE who had been treated with immunosuppressant therapy (IST; steroids and azathioprine since 2004. In 2011, she developed decreased sensation and weakness of the right hand, followed by vertigo and gait instability. The diagnosis of PML was made on the basis of brain MRI findings (posterior fossa lesions and JCV isolation from the cerebrospinal fluid (700 copies/ml. IST was immediately discontinued. Cidofovir, mirtazapine, mefloquine and cycles of cytarabine were sequentially added, but there was progressive deterioration with a fatal outcome 1 year after disease onset. This report discusses current therapeutic choices for PML and the importance of early infection screening when SLE patients present with neurological symptoms. In the light of recent reports of PML in SLE patients treated with rituximab or belimumab, we highlight that other IST may just as well be implicated. We conclude that severe lymphopenia was most likely responsible for JCV reactivation in this patient and discuss how effective management of lymphopenia in SLE and PML therapy remains an unmet need.

    Full Text Available A 30-year-old woman affected by Mixed Connective Tissue Disease with scleroderma spectrum developed a facial eruption, a clinical and histological characteristic of subacute cutaneous lupus erythematosus (SCLE. Speckled anti-nuclear antibodies, high-titer anti-ribonucleoprotein1, anti-Sm, anti-Cardiolipin (aCL IgG/IgM, and anti-Ro/SSA antibodies were positive. SCLE was resistant to Azathioprine, Hydroxychloroquine, and Methotrexate while Mycophenolate Mofetil was suspended due to side effects. Subsequently, the patient was treated with three cycles of therapeutic plasma exchange (TPE followed, one month after the last TPE, by the anti-CD20 antibody Rituximab (RTX (375 mg/m2 weekly for 4 weeks. Eight and 16 months later the patient received other two TPE and RTX cycles, respectively. This therapeutic approach has allowed to obtain a complete skin healing persistent even after 8-month follow-up. Moreover, mitigation of Raynaud's phenomenon, resolution of alopecia, and a decline of aCL IgG/IgM and anti-Ro/SSA antibodies were observed.

    Our objective was to evaluate our overall experience in pediatric renal transplantation. Between March 1976 and March 2004, 1,600 live-donor kidney transplantations were carried out in our center; 216 of the patients were 18 years old or younger (mean age 12.9 years). There were 136 male patients and 80 female patients. The commonest causes of end-stage renal disease (ESRD) were renal dysplasia (22%), nephrotic syndrome (20%), hereditary nephritis (16%), and obstructive uropathy (16%). Of the donors, 94% were one-haplotype matched and the rest were identical. Pre-emptive transplantation was performed in 51 (23%) patients. Triple-therapy immunosuppression (prednisone + cyclosporine + azathioprine) was used in 78.2% of transplants. Rejection-free recipients constituted 47.7%. Hypertension (62%) was the commonest complication. A substantial proportion of patients (48%) were short, with height standard deviation score (SDS) less than -1.88. The overall infection rate was high, and the majority (53%) of infections were bacterial. The graft survival at 1 year, 5 years and 10 years were 93.4%, 73.3% and 48.2%, respectively, while the patients' survival at 1, 5 and 10 years were 97.6%, 87.8% and 75.3%, respectively. Despite long-term success results of pediatric renal transplantation in a developing country, there is a risk of significant morbidity.

    Full Text Available Wegener′s granulomatosis (WG is a necrotizing granulomatous vasculitis invol-ving the nose, paranasal sinuses, lungs, and kidneys. Ocular involvement can occur in about 50% of cases. There are very few reports of WG with orbital inflammation and exorbitism. We report a case of a female patient who presented with exorbitism related to orbital inflammation secondary to WG, with renal involvement. A 29-year-old woman with a previous history of recurrent pan-sinusitis presented with bilateral exophthalmos and renal failure with rapidly progressive glo-merulonephritis. Computed tomography showed extensive bilateral soft tissue in the retro-orbital area. Immunologic tests showed the presence of type-C anti-neutrophil cytoplasmic antibodies and renal biopsy revealed pauci immune crescentic glomerulonephritis. The patient was treated with corticosteroids and pulses of cyclophosphamide followed by azathioprine and trimethoprim-sulfamethoxazole. After a follow-up of 10 months, the renal outcome was favorable with improvement of renal function but there was persistence of exorbitism and loss of visual function. Our case suggests that WG should be considered in the differential diagnosis of persistent bila-teral exophthalmos. Prompt recognition of this early manifestation is important for the institution of early treatment.

    2011-01-01

    Full Text Available Die Neurosarkoidose ist eine seltene Komplikation der Sarkoidose und wird mit einer Prävalenz von 5–15 % beschrieben. Ihr klinisches Bild ist sehr variabel und oft Folge einer aseptischen granulomatösen Meningitis. Diese führt häufig zu Hirnnervenaffektionen oder einer aseptischen Meningitis mit Liquorzirkulationsstörungen. Auch intraparenchymatöse Granulome kommen vor, häufig mit Befall basaler mittelliniennaher Strukturen wie Hypothalamus und Hypophyse, die zu einer Enzephalopathie führen können. Das MRT besitzt einen hohen diagnostischen Stellenwert, die Befunde sind allerdings nicht spezifisch und können sehr variabel sein. Daher bleibt der histologische Granulomnachweis Goldstandard für die Diagnose einer Neurosarkoidose, was aber nur bei wenigen Patienten möglich ist. Laboruntersuchungen sind wenig sensitiv und spezifisch, was die Neurosarkoidose zu einer diagnostischen Herausforderung macht, insbesondere wenn Zeichen einer systemischen Sarkoidose fehlen. Angesichts der erheblichen Morbidität der Erkrankung sollte eine frühe und konsequente Behandlung erfolgen. Dies geschieht in der Regel mit Kortikosteroiden, unterstützt durch Immunsuppressiva wie Azathioprin oder Methotrexat.

    A 37-year old woman presented with a 9-year history of hepatitis of unknown origin and aminotransferases within a 3-fold upper limit of normal. Autoimmune hepatitis (AIH) was diagnosed on the basis of elevated aminotransferases, soluble liver antigen/liver pancreas (SLA/LP) autoantibodies and characteristic histology.Immunosuppressive therapy led to rapid normalization of aminotransferases. Two years later, the patient developed left sided hemisensory deficits under maintenance therapy of prednisolone and azathioprine (AZT). Later she developed right foot drop and paraesthesia in the ulnar innervation territory on both sides. Magnetic resonance imaging (MRI) and cerebral panangiography suggested cerebral vasculitis. Neurological investigation and electromyography disclosed multiplex neuritis (MN) probably due to vasculitis. Consistent with this diagnosis, autoantibodies to extractable nuclear antigens were detectable in serum. Immunosuppression was changed to oral 150 mg cyclophosphamide (CPM0) per day. Prednisolone was increased to 40 mg/d and then gradually tapered to 5 mg. Oral CPM was administered up to a total dose of 40 g and then substituted by 6 times of an intervall infusion therapy of CPM (600 mg/m2).Almost complete motoric remission was achieved after 3 mo of CPM. Sensibility remained reduced in the right peroneal innervation territory. Follow-up of cranial MRI provided stable findings without any new or progressive lesions. This is the first report of multiplex neuritis in a patient with autoimmune hepatitis.

    2012-01-01

    Adamantiades-Behcet's disease (ABD) is a chronic,relapsing,systemic vasculitis of unknown etiology.It is more prevalent in populations along the ancient Silk Road from Eastern Asia to the Mediterranean Basin,and most frequently affects young adults between the second and fourth decades of life.ABD-complicated gastroenteropathy is a significant cause of morbidity and mortality,with abdominal pain as the most common symptom.The ileocecal region is affected predominantly,with ulcerations that may lead to penetration and/or perforation,whereas other parts of the gastrointestinal system including the esophagus and stomach can also be affected.Endoscopy is useful to locate the site and extent of the lesions,and tissue biopsy is often warranted to examine the histopathology that is often suggestive of underlying vasculitis of small veins/venules or,alternatively in some cases,nonspecific inflammation.Bowel wall thickening is the most common finding on computed tomography scan.Treatment is largely empirical since well-controlled studies are difficult to conduct due to the heterogeneity of the disease,and the unpredictable course with exacerbation and remission.Corticosteroids with or without other immunosuppressive drugs,such as cyclophosphamide,azathioprine,sulfasalazine,tumor necrosis factor α antagonist or thalidomide should be applied before surgery,except in emergency.

  3. Systemic and non-systemic vasculitis affecting the peripheral nerves.

    2009-06-01

    Vasculitis affecting the peripheral nerves predominantly manifests as subacute, progressive, asymmetric sensorimotor polyneuropathy or mononeuritis multiplex, and more rarely as painful mononeuropathy, pure sensory neuropathy, neuropathy of the cranial nerves, plexopathy, or as autonomic neuropathy. Vasculitic neuropathy may occur isolated or non-isolated (systemic) together with involvement of other organs. Systemic vasculitis with involvement of the peripheral nerves is further subdivided into primary (Takayasu syndrome, giant cell arteritis, classical panarteritis nodosa, thrombangitis obliterans, Kawasaki disease, Churg-Strauss syndrome, Wegener granulomatosis, cryoglobulinemic vasculitis, Behcet disease, microscopic polyangitis, Schoenlein Henoch purpura) or secondary systemic vasculitis (autoimmune connective tissue diseases, vasculitis from infection, sarcoidosis, malignancy, drugs, radiation, or diabetes). In addition to routine laboratory investigations and nerve conduction studies, nerve biopsy is essential for diagnosing the condition and to delineate it from differentials, although its sensitivity is only approximately 60%. Therapy of non-viral vasculitic neuropathy is based on corticosteroids and cyclophosphamide alone or in combination. Additional options include azathioprine, methotrexate, mycophenolate mofetil, or rituximab. In single cases immunoglobulins, immunoadsorbtion, or plasma exchange have been successfully applied. In case of virus-associated vasculitis interferon-alpha plus lamivudine or ribaverin may be beneficial.

    2016-05-01

    A European League Against Rheumatism (EULAR) task force was established to define points to consider on use of antirheumatic drugs before pregnancy, and during pregnancy and lactation. Based on a systematic literature review and pregnancy exposure data from several registries, statements on the compatibility of antirheumatic drugs during pregnancy and lactation were developed. The level of agreement among experts in regard to statements and propositions of use in clinical practice was established by Delphi voting. The task force defined 4 overarching principles and 11 points to consider for use of antirheumatic drugs during pregnancy and lactation. Compatibility with pregnancy and lactation was found for antimalarials, sulfasalazine, azathioprine, ciclosporin, tacrolimus, colchicine, intravenous immunoglobulin and glucocorticoids. Methotrexate, mycophenolate mofetil and cyclophosphamide require discontinuation before conception due to proven teratogenicity. Insufficient documentation in regard to fetal safety implies the discontinuation of leflunomide, tofacitinib as well as abatacept, rituximab, belimumab, tocilizumab, ustekinumab and anakinra before a planned pregnancy. Among biologics tumour necrosis factor inhibitors are best studied and appear reasonably safe with first and second trimester use. Restrictions in use apply for the few proven teratogenic drugs and the large proportion of medications for which insufficient safety data for the fetus/child are available. Effective drug treatment of active inflammatory rheumatic disease is possible with reasonable safety for the fetus/child during pregnancy and lactation. The dissemination of the data to health professionals and patients as well as their implementation into clinical practice may help to improve the management of pregnant and lactating patients with rheumatic disease.

    Full Text Available BackgroundType B insulin resistance syndrome is a manifestation of autoantibodies to the insulin receptor that results in severe hyperglycemia and acanthosis nigricans. However, the mechanisms by which these autoantibodies induce hypoglycemia are largely unknown. In this paper, we report the case of patient with type B insulin resistance syndrome who presented with frequent severe fasting hypoglycemia and acanthosis nigricans.MethodsTo evaluate the mechanism of hypoglycemia, we measured the inhibition of insulin binding to erythrocytes and IM9 lymphocytes in a sample of the patient's dialyzed serum before and after immunosuppressive therapy.ResultsIn the patient's pre-treatment serum IgG, the binding of 125I-insulin to erythrocytes was markedly inhibited in a dose-dependent manner until the cold insulin level reached 10-9 mol/L. We also observed dose-dependent inhibition of insulin binding to IM9 lymphocytes, which reached approximately 82% inhibition and persisted even when diluted 1:20. After treatment with glucocorticoids, insulin-erythrocyte binding activity returned to between 70% and 80% of normal, while the inhibition of insulin-lymphocyte binding was reduced by 17%.ConclusionWe treated a patient with type B insulin resistance syndrome showing recurrent fasting hypoglycemia with steroids and azathioprine. We characterized the patient's insulin receptor antibodies by measuring the inhibition of insulin binding.

    To report the long-term outcome of deceased donor kidney transplantation in children with emphasis on the use of an intensive initial immunosuppression protocol using R-ATG as antibody induction. Between January 1991 and December 1997, 82 deceased donor kidney transplantations were performed in 75 pediatric recipients. Mean recipient age at transplantation was 12.9 yr and the mean follow-up period was 12.6 yr. All patients received quadruple immunosuppression with steroid, cyclosporine, azathioprine, and antibody induction using R-ATG-Fresenius. Actual one, five, and 10 yr patient survival rates were 99%, 97%, and 94%, respectively; only one patient (1.2%) developed PTLD. Actual one, five, and 10 yr overall graft survival rates were 84%, 71%, and 50%, respectively; there were five cases (6%) of graft thrombosis and the actual immunological graft survival rates were 91%, 78%, and 63% at one, five, and 10 yr, respectively. The use of an intensive initial immunosuppression protocol with R-ATG as antibody induction is safe and effective in pediatric recipients of deceased donor kidneys with excellent immunological graft survival without an increase in PTLD or other neoplasms over a minimum 10-yr follow up.

    2014-06-01

    Herein we summarize the clinical presentation, treatment and outcome of neuro-ophthalmologic manifestations in patients with systemic lupus erythematosus (SLE). We performed a systematic review of the neuro-ophthalmologic manifestations of SLE reported in the English literature from 1970 to 2010 by a Medline search. The prevalence of neuro-ophthalmologic manifestations is 3.6% in adult and 1.6% in childhood SLE patients. Neuro-ophthalmologic manifestations of SLE are highly variable, with the commonest presentation being optic neuritis, followed by myasthenia gravis, visual field defects and pseudotumor cerebri. The underlying pathology was thought to be either SLE activity or its vascular complications. Most neuro-ophthalmologic manifestations of SLE are responsive to high-dose glucocorticoids. Anticoagulation is indicated when there is concomitant antiphospholipid syndrome. SLE-related neuromyelitis optica is often refractory to treatment and 92% of patients require multiple immunosuppressive protocols. Neuro-ophthalmologic manifestations of SLE are uncommon but heterogeneous. The prognosis of neuro-ophthalmologic manifestations in SLE is generally good because of their rapid response to glucocorticoids. Relapses of these manifestations may be reduced by the use of maintenance immunosuppression. Cyclophosphamide, azathioprine, plasmapheresis, intravenous immunoglobulin and rituximab can be considered in glucocorticoid-dependent or refractory cases. Anticoagulation is indicated when there is concomitant antiphospholipid syndrome.

    Juvenile systemic lupus erythematosus (JSLE) is a complex multisystemic autoimmune disorder of unknown cause. It accounts for about one in five cases of SLE. The tendency for SLE to run a fulminant course when it starts in childhood has made JSLE a potentially more severe disease than adult SLE. Reports of JSLE from sub-Saharan Africa are scanty in spite of the increasing reports of adult SLE. We conducted a 4-year retrospective study of JSLE cases seen at the Lagos State University Teaching Hospital between January 2010 and December 2014. Out of the 12 patients studied, eight were girls and four were boys. All patients had positive antinuclear antibody and extractable nuclear antibody tests. Anti-dsDNA antibody was positive in 10 patients. Eight patients had renal disease while four patients had neuropsychiatric manifestations. Haematological abnormalities and constitutional symptoms were present in all patients. Patients were treated with pulse methylprednisolone, oral prednisolone, hydroxychloroquine and azathioprine. Three patients also received rituximab. In conclusion, JSLE exists in Nigeria and exhibits clinical and immunological characteristics similar to its pattern in other parts of the world. It is, however, diagnosed late and is possibly being underdiagnosed as there is no paediatric rheumatologist in the country.

    The purpose of this study is to explore the possible applicability of Sterculia urens gum as a novel carrier for colonic delivery system of a sparingly soluble drug, azathioprine. The study involves designing a microflora triggered colon-targeted drug delivery system (MCDDS) which consists of a central polysaccharide core and is coated to different film thicknesses with blends of chitosan/Eudragit RLPO, and is overcoated with Eudragit L00 to provide acid and intestinal resistance. The microflora degradation property of gum was investigated in rat caecal medium. Drug release study in simulated colonic fluid revealed that swelling force of the gum could concurrently drive the drug out of the polysaccharide core due to the rupture of the chitosan/Eudargit coating in microflora-activated environment. Chitosan in the mixed film coat was found to be degraded by enzymatic action of the microflora in the colon. Release kinetic data revealed that the optimized MCDDS was fitted well into first-order model, and apparent lag time was found to be 6 hours, followed by Higuchi release kinetics. In vivo study in rabbits shows delayed T max, prolonged absorption time, decreased C max, and absorption rate constant (Ka), indicating a reduced systemic toxicity of the drug as compared to other dosage forms.

    Four renal transplant patients on immunosuppressive therapy who presented with acute myeloid leukaemia are described. In two cases, azathioprine may have played an important role as a cofactor in leukaemogenesis. In a third case, the alkylating agent cyclophosphamide may have contributed. All patients were treated for leukaemia with full doses of cytotoxic chemotherapy and, in each case, a functioning renal allograft was preserved throughout the treatment despite attenuation of immunosuppressive therapy. Three patients achieved complete remission. Of the three, one is surviving at 2 years and two expired during the pancytopenic phase of their treatment with no active leukaemia present, and with intact renal function. As increasing expertise in the field of organ transplantation allows patients to survive longer, such patients' exposure to immunosuppressive and potentially leukaemogenic drugs is prolonged. The risk of secondary neoplasia has been previously documented in this population. Two of the four cases reported here suffered from polycystic kidney disease as their underlying condition. While this report suggests that the leukaemias are related to renal transplantation, we cannot rule out an association with the underlying disease which led to the transplant. This report further suggests that the leukaemia that develops in such patients may respond to standard therapy, and that such treatment does not compromise the transplanted kidney.

  13. Therapeutic advances and future prospects in immune-mediated inflammatory myopathies.

    2008-11-01

    THE INFLAMMATORY MYOPATHIES INCLUDE THREE DISTINCT ENTITIES: polymyositis (PM), dermatomyositis (DM), and inclusion body myositis (IBM). A T-cell-mediated cytotoxic process in PM and IBM and a complement-mediated microangiopathy in DM are the hallmarks of the underlying autoimmune processes. The most consistent therapeutic problem remains the distinction of PM from the difficult-to-treat mimics such as s-IBM, necrotizing myopathies and inflammatory dystrophies. This review provides a step-by-step approach to the treatment of inflammatory myopathies, highlights the common pitfalls and mistakes in therapy, and identifies the emerging new therapies. In uncontrolled studies, PM and DM respond to prednisone to some degree and for some period of time, while a combination with one immu-nosuppressive drug (azathioprine, cyclosporine, mycophenolate, methotrexate) offers additional benefit or steroid-sparing effect. In contrast, IBM is resistant to most of these therapies, most of the time. Controlled studies have shown that IVIg is effective and safe for the treatment of DM, where is used as a second, and at times first, line therapy. IVIg seems to be also effective in the majority of patients with PM based on uncontrolled series, but it offers transient help to a small number of patients with IBM especially those with dysphagia. Bona fide patients with PM and DM who become resistant to the aforementioned therapies, may respond to rituximab, tacrolimus or rarely to an tumor necrosis factor alpha inhibitor. For IBM patients, experience with alemtuzumab, a T-cell-depleting monoclonal antibody, is encouraging.

  14. Clinical trials in CIDP and chronic autoimmune demyelinating polyneuropathies.

    Dalakas, Marinos C

    2012-05-01

    The main chronic autoimmune neuropathies include chronic inflammatory demyelinating polyneuropathy (CIDP), multifocal motor neuropathy (MMN), and anti-myelin-associated glycoprotein (MAG) demyelinating neuropathy. On the basis of randomized controlled studies, corticosteroids, intravenous immunoglobulin (IVIg), and plasmapheresis provide short-term benefits in CIDP. MMN responds only to IVIg. Because in MMN and CIDP, IVIg infusions are required every 3-6 weeks to sustain benefits or long-term remissions, there is a need for "IVIg-sparing" agents. In CIDP, immunosuppressive drugs, such as azathioprine, cyclosporine, methotrexate, mycophenolate, and cyclophosphamide, are used, but controlled trials have not shown that they are effective. Controlled trials have also not shown benefit to any agents in anti-MAG neuropathy. However, clinicians use many immunosuppressive drugs in both settings, but all have potentially serious side effects and are only effective in some patients. Thus, there is a need for new therapies in the inflammatory and paraproteinemic neuropathies. New agents targeting T cells, B cells, and transmigration and transduction molecules are discussed as potential treatment options for new trials. The need for biomarkers that predict therapeutic responses or identify patients with active disease is emphasized, and the search for better scoring tools that capture meaningful changes after response to therapies is highlighted.

  15. Current treatment of the inflammatory myopathies.

    Science.gov (United States)

    Dalakas, M C

    1994-11-01

    Among the main concerns regarding the current therapy for the inflammatory myopathies are a lack of adequate controlled trials, a lack of objective means to reliably measure muscle strength, lack of natural history data, consideration of polymyositis, dermatomyositis, and inclusion-body myositis as a homogeneous group of inflammatory myopathies, and reliance on nonspecific markers for determining prognosis and assessing response to therapies. Prednisone remains the drug of choice in treating these disorders, although a controlled trial has never been undertaken to study its efficacy. Among the steroid-sparing agents, azathioprine, methotrexate, cyclosporine, and chlorambucil are used with invariably low to moderate success. There are no results of controlled trials to indicate whether one of these drugs is superior to another. Intravenous immunoglobulin, which is very expensive, was shown in a controlled trial to be effective in steroid-resistant dermatomyositis not only in dramatically improving muscle strength and skin rash but also in resolving the underlying immunopathology. Controlled trials of intravenous immunoglobulin in patients with polymyositis and inclusion-body myositis are under way. Inclusion-body myositis has emerged as a common inflammatory myopathy that is predictably disabling and resistant to most therapies.

    Crohn's disease is a chronic inflammatory condition affecting the gastrointestinal tract at any point from the mouth to the rectum. Patients may experience diarrhea, abdominal pain, fever, weight loss, abdominal masses, and anemia. Extraintestinal manifestations of Crohn's disease include osteoporosis, inflammatory arthropathies, scleritis, nephrolithiasis, cholelithiasis, and erythema nodosum. Acute phase reactants, such as C-reactive protein level and erythrocyte sedimentation rate, are often increased with inflammation and may correlate with disease activity. Levels of vitamin B12, folate, albumin, prealbumin, and vitamin D can help assess nutritional status. Colonoscopy with ileoscopy, capsule endoscopy, computed tomography enterography, and small bowel follow-through are often used to diagnose Crohn's disease. Ultrasonography, computed axial tomography, scintigraphy, and magnetic resonance imaging can assess for extraintestinal manifestations or complications (e.g., abscess, perforation). Mesalamine products are often used for the medical management of mild to moderate colonic Crohn's disease. Antibiotics (e.g., metronidazole, fluoroquinolones) are often used for treatment. Patients with moderate to severe Crohn's disease are treated with corticosteroids, azathioprine, 6-mercaptopurine, or anti-tumor necrosis factor agents (e.g., infliximab, adalimumab). Severe disease may require emergent hospitalization and a multidisciplinary approach with a family physician, gastroenterologist, and surgeon.

  17. HYPERTENSION IN RENAL ALLOGRAFT RECIPIENTS

    Objective To further evaluate the effect of hypertension on renal graft function, and the relationship between hypertension, hyperlipoidemia and ischemic heart disease. Methods 102 renal transplant recipients with a functioning renal graft for more than 1 year were enrolled in this study. Renal function was followed for the further 24 months. Results The overall prevalence of hypertension was 89.2%(91/102) and 36.2%(33/91) hypertensive patients had uncontrolled blood pressure. After 24 months those with high blood pressure had significantly higher Scr levels than normotensive patients (P<0.05). The number of different antihypertensive classes required was related to Scr (P<0.05). Plasma cholesterol levels in hypertension patients especially in blood pressure uncontrolled group were significantly elevated (P<0.01). Ischemic heart disease was more common in hypertensive patients (P<0.05). Cyclosporine A was associated with hypertension more frequently than azathioprine and FK506, whereas low-dose prednisolone did not appear to influence blood pressure. Conclusion The data further confirmed that hypertension was associated with hyperlipidemia and ischemic heart disease, and emerged as a predictor of renal graft dysfunction. Whether cyclosporine A should be converted to new immunosuppressive agents and which class of antihypertensive medication is more effective in this population remain open questions.

    Full text. In recently years many reports have published of unusual or unexpected changes in the biodistribution of radiopharmaceuticals which do not correlate with normality or disease. Whilst many extraneous factors can alter tracer kinetics it has become apparent that concomitant patient medication can be such a factor. If the clinician is unaware that patient is on drug therapy difficulties arise in making a accurate diagnosis. Most drug/radio pharmaceutical effects are those in which the functional status of the organ is altered as a result of the pharmacological action of the drug. Examples here are narcotic analgesics such as methadone, pethidine and morphine which cause spasm of the biliary tract due to contraction of the sphincter of Oddi and an altered transit time of the technetium labelled tracer. Cytotoxic drugs such as cyclophosphamide and vincristine can markedly affect tumour uptake of 67-gallium so that litter or no activity is taken up by the tumour. Nifedipine, because of its powerful calcium channel blocking activity is known to affect the radiolabelling of white cells and red cells and to affect uptake of Tc-99 m MDP into bones. Other important and confusing effects are caused by phenothiazines, cimetidine and oral contraceptives. In recent years it has been reported that drugs such as cyclosporin, azathioprine and heparin and derivatives of heparin can markedly interfere with cell labelling procedures. This review will consider some of the clinical effects of drugs and will also address the reporting of instances of drug/radio pharmaceutical interactions

    Full Text Available Refractory celiac disease (RCD is when malabsorption symptoms and villous atrophy persist despite strict adherence to a gluten free diet (GFD for more than 12 months and other causes of villous atrophy have been ruled out.  RCD is considered a rare disease and almost exclusively occurs in adults. Persistent diarrhea, abdominal pain, weight loss are the most common symptoms in RCD. Also, anemia, fatigue, malaise, thromboembolic events and coexisting autoimmune disorders are frequent. Diagnosis of RCD is based on other causes of unresponsiveness to the GFD, particularly collagenous sprue, ulcerative jejunitis, and enteropathy-associated T-cell lymphoma. Many disorders such as autoimmune enteropathy, tropical sprue, common variable immunodeficiency, and intolerance to non-gluten dietary proteins may have similar histological findings but not necessarily identical with CD and therefore should be excluded. Repeat intestinal biopsy may help to differentiate causes of non-responsive CD associated with ongoing villous atrophy (e.g., gluten contamination, small-bowel bacterial overgrowth, RCD. There are 2 subtypes of RCD according to absence (type I or presence (type II of an abnormal intraepithelial lymphocyte population. RCD type 1 usually becomes better with a combination of aggressive nutritional support, adherence to GFD, and pharmacologic therapies such as prednisone, budesonide and azathioprine. For RCD type 2, more aggressive therapeutic approach is needed since clinical response to therapies is less certain and may evolve into aggressive enteropathy associated T-cell lymphoma and the prognosis is poor.   Key words: Celiac Disease, Refractory.  

  1. Successful Discontinuation of Infliximab in a Refractory Case of Vasculo-Behçet Disease

    Full Text Available Reports have shown that antitumor necrosis factor alpha (anti-TNF-α agents including infliximab (IFX can dramatically suppress the disease activity of refractory vasculo-Behçet disease (vasculo-BD. However, it is completely unknown whether we can discontinue anti-TNF-α agents under clinical remission. A 31-year-old patient with vasculo-BD was initially treated with a high dose of steroid and intravenous cyclophosphamide therapy. Six months later, however, the disease recurred. IFX was administered and immediately the disease activity was reduced. Fortunately, we could discontinue IFX after 18-month remission and no recurrence has been observed. Based on previous reports and our patient, all patients who could discontinue IFX sustained clinical remission for at least one year, continued taking immunosuppressive agents such as methotrexate and azathioprine, and had vascular involvements only in non-life-threatening major vessels such as leg or arm arteries/veins. This is a report suggesting the possibility of discontinuation of IFX in vasculo-BD.

    2015-09-01

    Full Text Available Autoimmune hepatitis is a chronic liver inflammation resulting from deregulation of immune tolerance mechanisms. Multiple sclerosis is also an inflammatory disease in which the insulating covers of nerve cells in the brain and spinal cord are damaged. Here we present a case of an 18 year old female with multiple sclerosis was treated with glatiramer acetate and with interferon beta 1a at our hospital. Seven months after initiating treatment, liver dysfunction occurred. Clinical and laboratory findings were suggestive of drug-induced hepatitis, which led to discontinuation of treatment with interferon. Facing a new episode of acute hepatitis one year later, she was subjected to a liver biopsy, and the analysis of autoantibodies was positive for smooth muscle antibodies. Given the diagnosis of autoimmune hepatitis she started therapy with prednisolone and azathioprine, with good clinical and analytical response. Besides, the demyelinating lesions of multiple sclerosis became lower. In conclusion, there are only a few cases that describe the association of autoimmune hepatitis with multiple sclerosis, and there is a chance both diseases have the same autoimmune inflammatory origin.

    Pulmonary abnormalities are not frequently encountered in patients with inflammatory bowel diseases. However, lung toxicity can be induced by conventional medications used to maintain remission, and similar evidence is also emerging for biologics. We present the case of a young woman affected by colonic Crohn's disease who was treated with oral mesalamine and became steroid-dependent and refractory to azathioprine and adalimumab. She was referred to our clinic with a severe relapse and was treated with infliximab, an anti-tumor necrosis factor α (TNF-α) antibody, to induce remission. After an initial benefit, with decreases in bowel movements, rectal bleeding and C-reactive protein levels, she experienced shortness of breath after the 5(th) infusion. Noninfectious interstitial lung disease was diagnosed. Both mesalamine and infliximab were discontinued, and steroids were introduced with slow but progressive improvement of symptoms, radiology and functional tests. This represents a rare case of interstitial lung disease associated with infliximab therapy and the effect of drug withdrawal on these lung alterations. Given the increasing use of anti-TNF-α therapies and the increasing reports of pulmonary abnormalities in patients with inflammatory bowel diseases, this case underlines the importance of a careful evaluation of respiratory symptoms in patients undergoing infliximab therapy.

    Beginning in November 1981, eight patients with end stage diabetic nephropathy underwent renal cadaveric transplantation after TLI. Transplantation was done between 2 to 11 days after the end of a fractionated TLI to a total dose of 20 to 30 Gy. During the same observation period, 60 nondiabetic patients with end stage renal disease of different origin also received a cadaveric kidney graft, with a conventional regimen of immunosuppression that consists of anti-lymphocyte-globulin, tapering high doses of prednisone, and azathioprine. Phytohemagglutinin (PHA)-, concanavalin A (con A)-, and pokeweed mitogen (PWM)-induced blastogenesis, as well as the mixed lymphocyte reaction (MLR) and the cell-mediated lympholysis (CML) decreased progressively during the first months after conventional immunosuppression to 50% of the pretransplantation level, and remained there for the first year after transplantation. These tests were much more impaired after TLI and again no recovery occurred during the first year. In the clinic, the more profound immunosuppression in TLI patients was more frequently associated with viral infections (cytomegalovirus and herpes zoster). The incidence of rejections, however, was somewhat less frequent in the TLI-treated group and occurred significantly later. After TLI, the mean cumulative dose of steroids needed for kidney transplantation during the first year after transplantation could be substantially reduced.

    Full Text Available Abstract Background Neuromyelitis optica (NMO is an idiopathic, severe, inflammatory demyelinating disease of the central nervous system, that causes severe optic neuritis and myelitis attacks. Early discrimination between multiple sclerosis (MS and NMO is important, as optimum treatment for both diseases may differ considerably. Case Presentation We report a case of a patient who initially presented as longitudinally extensive transverse myelitis (LETM, having spastic upper extremities diparesis and spastic paraplegia, C2/C3 sensory level and urinary incontinence, as well as extensive inflammatory spinal cord lesions from C2 level to conus. After 5 months the patient had another attack of transverse myelitis, had electrophysiological findings consistent with optic neuritis, was seropositive for NMO-IgG (aquaporin-4 IgG and thus fulfilled NMO diagnostic criteria. Following treatment of disease attacks with pulse corticosteroid therapy and intravenous immunoglobulins, we included oral azathioprine in a combination with oral prednisone in the therapy. Since there was no significant clinical improvement, we decided to use cyclophosphamide therapy, which resulted in good clinical improvement and gradual decrease of cord swelling. Conclusion In this NMO case report we wanted to emphasize the extensiveness of inflammatory spinal cord changes in our patient, from C2 level to conus. In the conclusion it is important to say that accurate, early diagnosis and distinction from MS is critical to facilitate initiation of immunosuppressive therapy for attack prevention.

    Corticosteroids and 5-aminosalicylic acid are the primary standard therapy for inflammatory bowel disease. Recent immunologic data implicate an involvement of mast cell activation followed by increased histamine secretion and elevated tissue concentrations of histamine in the pathogenesis of ulcerative colitis. In the present case, the clinical course of a 35-year-old man with steroid-dependent chronic active ulcerative colitis, who did not respond to high-dose steroids, antibiotics, or azathioprine during 3 years, is reported. Clinical disease activity and established serological markers were recorded during 6 weeks of unsuccessful therapy and during the next 6 weeks, as a new nonsedative antihistaminergic drug, a mast cell stabilizer, and an hypoallergenic diet were implemented in addition to conventional therapy. Induction of remission was achieved within 2 weeks after treatment with fexofenadine, disodium cromoglycate, and an amino acid-based formula. Clinical disease activity, stool frequency, leukocytes, c-reactive protein, and orosomucoid levels in serum decreased rapidly. Daily steroid administration could be gradually reduced along with 6 weeks of this treatment. This report suggests that histamine and mast cell activity may be important pathophysiological factors responsible for persistent clinical and mucosal inflammatory activity in ulcerative colitis despite the use of steroids. In ulcerative colitis, patients unresponsive to conventional treatment, therapeutic considerations should also include an antiallergic approach when further signs of atopy or intestinal hypersensitivity are present.

    AIM: Prednisone and azathioprine represent the standard treatment for autoimmune hepatitis (AIH). However, only 65% of the patients enter complete histological remission. Recently, budesonide (BUD) was reported to be a promising alternative. In this study we assessed the efficacy and safety of BUD in AIH.METHODS: Eighteen patients (12 women, 6 men; mean age 45.4±21 years) with AIH were treated with BUD (Budenofalk(R)) 3 mg thrice daily and followed up for at least 24 wk. Seven patients also had features of primary biliary cirrhosis (n = 5) or primary sclerosing cholangitis (n = 2). Advanced liver fibrosis or cirrhosis was present in 6 patients.RESULTS: Fifteen (83%) patients had a complete clinical and biochemical remission. Ten patients, including five with acute hepatitis, were given BUD as first-line therapy, of which seven enter remission. Three patients,two with liver cirrhosis, did not improve. All patients with second-line therapy experienced long-term remission.A histological remission was also seen in three patients.Clinically relevant BUD-induced side effects were recorded only in patients with liver cirrhosis (n = 4).CONCLUSION: BUD is effective in remission induction in the majority of our patients with AIH. Side effects and treatment failure was mainly observed in patients with liver cirrhosis.

    Between February 1983 and July 1987, twelve patients underwent heart-lung transplantation at the University of Cape Town and the University of Munich. The patients included eight men and four women, whose ages ranged from 15 to 49 years (mean, 27 years). The underlying pathologic condition was idiopathic primary pulmonary hypertension in five cases, Eisenmenger's syndrome in four cases, idiopathic pulmonary fibrosis in one case, diffuse fibrosing alveolitis in one case, and chronic emphysema in one case. The immunosuppressive regimen consisted of cyclosporine A, azathioprine, and rabbit antithymocyte globulin (RATG) during the first 2 postoperative weeks; RATG was subsequently replaced by methylprednisolone. Pulmonary rejection frequently occurred in the absence of cardiac rejection; in one case, however, this situation was reversed. Two patients required retransplantation, which was undertaken for caseating pulmonary tuberculosis with obliterative bronchiolitis after 1 year in one case and for early pulmonary insufficiency after 2 days in the other case. There were no operative deaths, but three early deaths occurred, owing to respiratory insufficiency of unknown origin (10 days postoperatively), multiorgan failure (10 days postoperatively), and acute liver dystrophy (11 days postoperatively). Five weeks after operation, a fourth patient died of multi-organ failure. There were five late deaths, all of which resulted from infectious complications. Three patients, including one who underwent retransplantation, remain alive and well, 10 to 36 months postoperatively.

    Wegener's granulomatosis (WG) is a necrotizing granulomatous vasculitis involving the nose, paranasal sinuses, lungs, and kidneys. Ocular involvement can occur in about 50% of cases. There are very few reports of WG with orbital inflammation and exorbitism. We report a case of a female patient who presented with exorbitism related to orbital inflammation secondary to WG, with renal involvement. A 29-year-old woman with a previous history of recurrent pan-sinusitis presented with bilateral exophthalmos and renal failure with rapidly progressive glomerulonephritis. Computed tomography showed extensive bilateral soft tissue in the retro-orbital area. Immunologic tests showed the presence of type-C anti-neutrophil cytoplasmic antibodies and renal biopsy revealed pauci immune crescentic glomerulonephritis. The patient was treated with corticosteroids and pulses of cyclophosphamide followed by azathioprine and trimethoprim-sulfamethoxazole. After a follow-up of 10 months, the renal outcome was favorable with improvement of renal function but there was persistence of exorbitism and loss of visual function. Our case suggests that WG should be considered in the differential diagnosis of persistent bilateral exophthalmos. Prompt recognition of this early manifestation is important for the institution of early treatment.

    Full Text Available Pyoderma gangrenosum is an extraintestinal manifestation of inflammatory bowel disease that can be therapeutically troublesome. We comment on the case of a patient with clinically inactive ulcerat-ive colitis who progressively developed necrotic lesions on both tibial aspects of his legs, which corresponded both clinically and histologically to pyoderma gangrenosum. Treatment with steroids and azathioprine could not control this complication. A single dose of infliximab 5 mg/kg was given, achieving an impressive response of the skin lesions followed by complete healing 3 months later. Infliximab can be useful in the management of refractory extraintestinal manifestations of inflammatory bowel disease.Dentro de las manifestaciones extraintestinales de la enfermedad inflamatoria intestinal, el pioderma gangrenoso plantea con frecuencia dificultades terapéuticas. Presentamos el caso de un enfermo diagnosticado de colitis ulcerosa, inactiva en ese momento, que presentó un pioderma gangrenoso en miembros inferiores y no respondió a esteroides y azatioprina. Se administró una dosis de 5 mg/kg de infliximab obteniendo una rápida mejoría de las lesiones y la completa curación a los 3 meses. Infliximab puede ser útil en manifestaciones extraintestinales de la enfermedad inflamatoria intestinal, como el pioderma gangrenoso, si no responden a los tratamientos habituales.

    Full Text Available Christina M Gelbard1, Adelaide A Hebert1,21Departments of Dermatology; 2Pediatrics, University of Texas-Houston, Houston, TX, USAAbstract: Atopic dermatitis is a chronic, inflammatory skin condition that affects 10% to 20% of children and 1% to 3% of adults in the US. Symptoms often result in sleeplessness, psychological stress, poor self-esteem, anxiety, and poor school or work performance. The cost of atopic dermatitis is estimated to be US$0.9 to 3.8 billion every year. Topical steroids are first-line treatment for atopic dermatitis, and recent advances in vehicle technologies have resulted in improved patient tolerability and compliance. Topical calcineurin inhibitors are also safe and effective topical treatments for atopic dermatitis, and provide an additional therapeutic option for patients with this disease. Systemic immunomodulators are used in the treatment of severe refractory disease. Cyclosporine, methotrexate, azathioprine, mycophenolate mofetil, and interferon gamma have been used in the management of severe atopic dermatitis. This review highlights the current and emerging trends in the treatment of atopic dermatitis.Keywords: atopic dermatitis, topical corticosteroids, calcineurin inhibitors, methotrexate, cyclosporine, mycophenolate mofetil, IFN-γ

    We report the case of a 38-year-old man who presented with severe diarrhea, weight loss of 10 kg, ankles paresthesia and severe motor weakness in the left fibular nerve territory after introduction of azathioprine and corticosteroid for proteinuria. Coloscopy and gastroscopy revealed a typical aspect of Whipple disease (WD), associated with both positive PAS staining and specific immunohistochemistry. T. whipplei PCR results were positive in blood, faeces, saliva and duodenal biopsy specimens. Diagnosis of WD with systemic manifestations was retained and doxycycline plus hydroxychloroquine therapy were started. This treatment improved joint pain, and skin and intestinal symptoms. One month later, our patient presented with fever and an important inflammatory syndrome (CRP 150 mg/dL and 16.8 10(9)/L leukocytes), while no infection was found despite a thorough review. We concluded it was an immune reconstitution inflammatory syndrome (IRIS). Manifestations persisted despite increasing corticosteroids and thalidomide (200 mg/day) was introduced with good efficacy on these symptoms. WD may be revealed by non-specific symptoms such as weight loss or arthralgia, but also by many other misleading signs. Our observation illustrates the highly polymorphic clinical presentation of WD, and the diagnostic difficulties that may arise. This is also a new report of thalidomide effectiveness in IRIS in WD.

    Membranous nephropathy is a common cause of nephrotic syndrome in adults. It usually occurs secondary to underlying disease processes such as autoimmune disorders, malignancy, infection, and drugs. The presentation of nephrotic syndrome with concomitant precipitous decline in renal function warrants investigation of a coexistent disorder.We report the case of a 30-year-old male who presented with symptoms and signs of hypothyroidism.A diagnosis of Hashimoto's thyroiditis was contemplated based on the presence of high serum levels of antithyroglobulin and antithyroid peroxidase antibodies. Upon initiation of treatment with levothyroxine, patient symptomatology improved; however, the laboratory studies demonstrated continued elevated creatinine, hematuria, and proteinuria, which had not been addressed. Two months following treatment initiation, he had progressive deterioration in renal function and proteinuria. A renal biopsy revealed coexistent necrotizing and crescentic glomerulonephritis and membranous nephropathy.The final diagnosis was necrotizing, crescentic glomerulonephritis with superimposed membranous nephropathy likely secondary to Hashimoto's thyrodiitis.Induction treatment with oral cyclophosphamide and prednisone was started.At the end of 6 months of treatment, there was improvement in renal function and proteinuria and maintenance treatment with azathioprine and low-dose prednisone was initiated. This case highlights the importance of precise and detailed evaluation of patients with autoimmune diseases such as Hashimoto's thyroiditis particularly in the presence of active urine sediment. Proper evaluation and diagnosis of such patients has implications on the prognosis and response to treatment.

  16. Treatment Options for Primary Autoimmune Hemolytic Anemia: A Short Comprehensive Review.

    Until now, treatment of primary autoimmune hemolytic anemia of the warm type (wAIHA) is primarily based on immunosuppression. However, many patients do not respond adequately to treatment, and treated patients may develop severe side effects due to uncontrolled, mixed and/or long-lasting immunosuppression. Unfortunately, the newly used therapeutic monoclonal antibodies are unspecific and remain frequently ineffective. Thus, development of a specific therapy for AIHA is necessary. The ideal therapy would be the identification and elimination of the causative origin of autoimmunization and/or the correction or reprogramming of the dysregulated immune components. Blood transfusion is the most rapidly effective measure for patients who develop or may develop hypoxic anemia. Although some effort has been made to guide physicians on how to adequately treat patients with AIHA, a number of individual aspects should be considered prior to treatment. Based on my serological and clinical experience and the analysis of evidence-based studies, we remain far from any optimized therapeutic measures for all AIHA patients. Today, the old standard therapy using controlled steroid administration, with or without azathioprine or cyclophosphamide, is, when complemented with erythropoiesis-stimulating agents, still the most effective therapy in wAIHA. Rituximab or other monoclonal antibodies may be used instead of splenectomy in therapy-refractory patients.

    Introduction Immunosuppressive agents (ISA) have been used in multiple sclerosis (MS) for decades, frequently as off label licensed therapies. Given the new MS treatment landscape, what place do ISA have in combating MS? Methods We conducted a retrospective multicentre study to investigate the frequency of ISA prescription in 17 Italian MS centres, and to describe the clinical factors related to ISA use. Results Out of 6,447 MS patients, 2,034 (31.6%) were treated with ISA, with Azathioprine being the most frequently used ISA overall. MS patients treated with ISA alone were more frequently affected by the progressive course (both primary and secondary) of the disease (RRR 5.82, 95% CI 4.14–8.16, p<0.0001), had higher EDSS (RRR 3.69, 95% CI 2.61–5.21, p<0.0001), higher assignment age (RRR 1.04, 95% CI 1.03–1.06, p<0.0001) than patients treated with only disease modifying drugs (DMDs). Conclusions Progressive course, higher EDSS, higher assignment age were the strongest predictors of ISA prescription and use in our population. PMID:27348606

    Fetomaternal microchimerism suggests immunological tolerance between mother and fetus. Thus, we performed primary hematopoietic stem cell transplantation from a mismatched mother to thalassemic patient without an human leukocyte antigen-identical donor. Twenty-two patients with thalassemia major were conditioned with 60 mg/kg hydroxyurea and 3 mg/kg azathioprine from day -59 to -11; 30 mg/m(2) fludarabine from day -17 to -11; 14 mg/kg busulfan starting on day -10; and 200 mg/kg cyclophosphamide, 10 mg/kg thiotepa, and 12.5 mg/kg antithymocyte globulin daily from day -5 to -2. Fourteen patients received CD34(+)-mobilized peripheral blood and bone marrow progenitor cells; 8 patients received marrow graft-selected peripheral blood stem cells CD34(+) and bone marrow CD3/CD19-depleted cells. T-cell dose was adjusted to 2 x 10(5)/kg by fresh marrow cell addback at the time of transplantation. Both groups received cyclosporine for graft-versus-host disease prophylaxis for 2 months after transplantation. Two patients died (cerebral Epstein-Barr virus lymphoma or cytomegalovirus pneumonia), 6 patients reject their grafts, and 14 showed full chimerism with functioning grafts at a median follow-up of 40 months. None of the 14 patients who showed full chimerism developed acute or chronic graft-versus-host disease. These results suggest that maternal haploidentical hematopoietic stem cell transplantation is feasible in patients with thalassemia who lack a matched related donor.

    Full Text Available The development of cerebral venous thrombosis (CVT as a secondary complication of Crohn's disease (CD seems to be rare, but it is generally accepted that the disease activity of CD contributes to the establishment of a hypercoagulable state. Here, we describe a case of CVT that developed outside the active phase of CD. A 17-year-old male visited the emergency room because of a sudden onset of right-sided weakness and right-sided hypesthesia. He had been diagnosed with CD 1 year before and was on a maintenance regimen of mesalazine and azathioprine. He did not exhibit any symptoms indicating a CD flare-up (bloody stools, abdominal pain, complications, or weight loss. A brain MRI scan revealed an acute infarction of the left frontal cortex and a cortical subarachnoid hemorrhage. Additionally, a magnetic resonance venography revealed a segmental filling defect in the superior sagittal sinus and also the non-visualizability of some bilateral cortical veins. The characteristics of the present case suggest that the risk of CVT is most likely related to CD per se rather than disease activity associated with CD.

    Full Text Available Abstract Background Clinical presentation, diagnosis, management and outcome of molecularly defined congenital pulmonary alveolar proteinosis (PAP due to mutations in the GM-CSF receptor are not well known. Case presentation A 2 1/2 years old girl was diagnosed as having alveolar proteinosis. Whole lung lavages were performed with a new catheter balloon technique, feasible in small sized airways. Because of some interstitial inflammation in the lung biopsy and to further improve the condition, empirical therapy with systemic steroids and azathioprin, and inhaled and subcutaneous GMCSF, were used. Based on clinical measures, total protein and lipid recovered by whole lung lavages, all these treatments were without benefit. Conversely, severe respiratory viral infections and an invasive aspergillosis with aspergilloma formation occurred. Recently the novel homozygous stop mutation p.Ser25X of the GMCSF receptor alpha chain was identified in the patient. This mutation leads to a lack of functional GMCSF receptor and a reduced response to GMCSF stimulation of CD11b expression of mononuclear cells of the patient. Subsequently a very intense treatment with monthly lavages was initiated, resulting for the first time in complete resolution of partial respiratory insufficiency and a significant improvement of the overall somato-psychosocial condition of the child. Conclusions The long term management from early childhood into young adolescence of severe alveolar proteinosis due to GMCSF receptor deficiency requires a dedicated specialized team to perform technically demanding whole lung lavages and cope with complications.

  1. Efficient DNA interstrand crosslinking by 6-thioguanine and UVA radiation.

    Patients taking the immunosuppressant and anticancer thiopurines 6-mercaptopurine, azathioprine or 6-thioguanine (6-TG), develop skin cancer at a very high frequency. Their DNA contains 6-TG which absorbs ultraviolet A (UVA) radiation, and their skin is UVA hypersensitive, consistent with the formation of DNA photodamage. Here we demonstrate that UVA irradiation of 6-TG-containing DNA causes DNA interstrand crosslinking. In synthetic duplex oligodeoxynucleotides, the interstrand crosslinks (ICLs) can form between closely opposed 6-TG bases and, in a less favoured reaction, between 6-TG and normal bases on the opposite strand. In vivo, UVA irradiation of cultured cells containing 6-TG-substituted DNA also causes ICL formation and induces the chromosome aberrations that are characteristically associated with this type of DNA lesion. 6-TG/UVA activates the Fanconi anemia (FA) pathway via monoubiquitination of the FANCD2 protein. Cells defective in the FA pathway or other factors involved in ICL processing, such as XPF and DNA Polζ, are all hypersensitive to killing by 6-TG/UVA-consistent with a significant contribution of photochemical ICLs to the cytotoxicity of this treatment. Our findings suggest that sunlight-exposed skin of thiopurine treated patients may experience chronic photochemical DNA damage that requires constant intervention of the FA pathway.

    Abstract We report the case of a 17‐year‐old female patient with known hypertrophic cardiomyopathy and a Wolff‐Parkinson‐White syndrome. She came to our department for further evaluation of a new diagnosed dilated cardiomyopathy characterized by an enlargement of the left ventricle and a fall in ejection fraction. Clinically, she complained about atypical chest pain, arrhythmic episodes with presyncopal events, and dyspnea (NYHA III) during the last 6 months. Non‐invasive and invasive examinations including magnetic resonance imaging, electrophysiological examinations, and angiography did not lead to a conclusive diagnosis. Therefore, endomyocardial biopsies (EMBs) were taken to investigate whether a specific myocardial disease caused the impairment of the left ventricular function. EMB analysis resulted in the diagnosis of a virus‐negative, active myocarditis. Based on this diagnosis, an immunosuppressive treatment with prednisolone and azathioprine was started, which led to an improvement of cardiac function and symptoms within 3 months after initiating therapy. In conclusion, we show that external stress triggered by myocarditis can induce a reversible transition from a hypertrophic cardiomyopathy to a dilated cardiomyopathy phenotype. This case strongly underlines the need for a thorough and invasive examination of heart failure of unknown causes, including EMB investigations as recommend by the actual ESC position statement.

    Full Text Available Treatment of Wegener’s granulomatosis, often a life-threatening disease, has greatly improved, considering that before corticosteroids and immunosuppressives were available, the average survival time of patients amounted to no more than 5 months. The management of Wegener’s granulomatosis can be divided in two stages: induction of remission and maintenance of remission. The standard regimen for the induction of remission consists of cyclophosphamide, 2 mg/kg/day orally, in combination with prednisone, 1mg/Kg/day orally, with a gradual tapering once remission has been obtained. To lower the overall cumulative dose, monthly intravenous pulses of cyclophosphamide have been evaluated. Other alternative treatments as high doses of corticosteroids, methotrexate, or plasmapheresis have been proposed, together as prophylaxis with trimethoprim-sulfamethoxazole. To minimize toxicity, for maintenance therapy other drugs are also used such as methotrexate, azathioprine, cyclosporine. Frequent therapeutic changes are needed due to the great variability of the disease; while important aspects are the recognition and treatment of relapse, and include not only the management of resistant disease, but also some particular aspects such as disease in chronic dialysis, renal transplant, pregnancy. Other cytotoxic drugs like leflunomide or mycofenolic mofetil appear to be promising, while new efforts to identify more effective and less toxic therapies include biologic products, such as high-dose immunoglobulin, TNF antagonists and other monoclonal antibodies. Many different kind of clinical trials are going on to better evaluate the real efficacy and safety of these treatments in Wegener’s granulomatosis.

    We present herein the cases of two patients who developed idiopathic portal hypertension (IPH) following renal transplantation. Both patients had been treated with azathioprine and prednisolone for 6 years and 4 months and for 4 years and 7 months, respectively, and presented with splenomegaly and thrombocytopenia suggesting hypersplenism. Celiac angiography showed a dilated splenic artery and vein in both patients. When the splenic artery was obliterated with a balloon catheter in case 1, the portal venous pressure decreased from 51 cmH2O to 36 cmH2O, and the direction of the superiomesenteric venous blood flow became hepatopetal rather than hepatofugal. These results suggested that the spleen might have played an important role in the development of IPH in these two patients. A splenectomy was therefore performed, immediately following which the portal venous pressure decreased remarkably, and the esophageal varices disappeared during the postoperative follow-up period. Microscopic examination of liver biopsies taken at the operation revealed lymphoplasmacytic infiltration with bile duct hyperplasia but no evidence of periportal fibrosis, and electron microscopy demonstrated very mild perisinusoidal fibrosis. Thus, the histological changes seen in the livers of these patients seemed not to have caused the portal hypertension. In conclusion, although few patients develop IPH after renal transplantation, we should be aware of its possibility and consider splenectomy as the treatment of choice.

    Chronic intestinal pseudo-obstruction (CIP) is an infre-quent complication of an active systemic lupus erythema-tosus (SLE). We illustrate a case of SLE inactive-related CIP. A 51-year old female with inactive SLE (ECLAM score 2) was hospitalized with postprandial fullness, vomiting, abdominal bloating and abdominal pain. She had had no bowel movements for five days. Plain abdominal X-ray revealed multiple fluid levels and dilated small and large bowel loops with air-fluid levels. Intestinal contrast radiology detected dilated loops. CIP was diagnosed. The patient was treated with prokinetics, octreotide, claritromycin, rifaximin, azathioprine and tegaserod without any clinical improvement. Then methylprednisolone (500 mg iv daily) was started. After the first administration, the patient showed peristaltic movements. A bowel movement was reported after the second administration. A plain abdominal X-ray revealed no air-fluid levels. Steroid therapy was slowly reduced with complete resolution of the symptoms. The patient is still in a good clinical condition. SLE-related CIP is generally reported as a complication of an active disease. In our case, CIP was the only clinical demonstration of the SLE.

    This study reports major gastrointestinal complications in a group of 416 patients following kidney transplantation. Three hundred and ninety-nine patients received a cadaveric kidney while the other 17 received a living related organ. The immunosuppressive regimen changed somewhat during the course of the study but included azathioprine, prednisolone, antilymphocyte globulin, and cyclosporin. Perforations occurred in the colon (n = 6), small bowel (n = 4), duodenum (n = 2), stomach (n = 1), and esophagus (n = 1). There were five cases of acute pancreatitis, four of upper gastrointestinal and two of lower intestinal hemorrhage, two of acute appendicitis, one of acute cholecystitis, one postoperative mesenteric infarction, and two small bowel obstructions. Fifty percent of the complications occurred while patients were being given high-dose immunosuppression to manage either the early postoperative period or episodes of acute rejection. Ten percent of the complications had an iatrogenic cause. Of the 31 patients affected, 10 (30%) died as a direct result of their gastrointestinal complication. This high mortality appears to be related to the effects of the immunosuppression and the associated response to sepsis. Reduction of these complications can be achieved by improved surgical management, preventive measures, prompt diagnosis, and a reduced immunosuppressive protocol.

  7. Pregnancy in Systemic Lupus Erythematosus Patients with Nephritis

    Full Text Available Pregnancy in patients with lupus nephritis is a challenging clinical situation. Although not absolutely contraindicated, it is associated with increased risk for foetal and maternal complications, including foetal loss, preterm delivery, intrauterine growth retardation, hypertension, pre-eclampsia, nephritis flare, and, rarely, maternal death. The complication rate is further increased in the presence of antiphospholipid antibodies or the antiphospholipid syndrome. Proliferative classes of nephritis (III and IV also appear to confer excess risk for complications. Immunosuppressives such as cyclophosphamide and mycophenolate, and antihypertensives such as angiotensin-converting-enzyme (ACE inhibitors and angiotensin receptor blockers need to be stopped due to teratogenic effects. Agents like corticosteroids, azathioprine, and probably calcineurin inhibitors are considered compatible with gestation. Lupus activity needs to be assessed and carefully monitored. Thrombotic risk due to antiphospholipid antibodies, thrombotic events, or nephrosis needs to be evaluated and managed accordingly, with the use of aspirin and/or unfractioned or low molecular weight heparin. Differentiating between severe pre-eclampsia and lupus nephritis flare might require a renal biopsy, which might not always be feasible, for example after the 32nd gestational week or in a setting of uncontrolled hypertension or thrombocytopaenia. A 6-month history of quiescent disease on non-teratogenic agents seems to be associated with best chance for favourable outcomes. Pregnancy is optimally managed by a multidisciplinary team of experienced specialists, and close monitoring for disease activity during gestation; additionally, follow-up for maternal flare postpartum is also advised.

    Bullous pemphigoid (BP) is an autoimmune blistering disease that commonly occurs in the elderly. Immunosuppressive medications are effective at controlling the disease in the majority of cases. Mortality can occur as a consequence of severe disease or as a result of the therapies that are frequently employed as treatment. Commonly employed therapies include systemic corticosteroids, azathioprine and mycophenolate mofetil. In a small subset of patients, these first- and second-line therapies do not control disease or are not tolerated by the patients. Optional therapies include nicotinamide (niacinamide), tetracycline, intravenous immunoglobulin, cyclophosphamide, dapsone and methotrexate. The majority of BP patients are elderly, and several considerations need to be taken into account before a specific therapy is chosen. Methotrexate provides several advantages in the elderly population in terms of practicality, cost and tolerability. Several retrospective and prospective studies have evaluated its effectiveness in the treatment of BP in the elderly population. The results of these studies indicate that methotrexate is an effective therapy for BP and is a reasonable option for treatment in the elderly population, although maybe not as a first- or second-line therapy.

  9. The Outlier in All of Us: Why Implementing Pharmacogenomics Could Matter for Everyone.

    2016-04-01

    The field of pharmacogenomics originally emerged in the 1950s from observations that a few rare individuals had unexpected, severe reactions to drugs. As recently as just 6 years ago, prominent views on the subject had largely remained unchanged, with authors from the US Food and Drug Administration (FDA) citing the purpose of pharmacogenetics as "tailoring treatment for the outliers." It should not be surprising if this is the prevailing view--the best-studied pharmacogenomic drug examples are indeed just that, genetic explanations of extreme responses or susceptibilities among usually a very small fraction of the human population. Thiopurine methyltransferase (TPMT) deficiency as a cause of severe myelosuppression upon treatment with azathioprine or mercaptopurine is found as a heterozygous trait in only ∼ 10% of patients, and homozygous (deficiency) carriers are even more rare--occurring in fewer than 1 in 300 patients. Malignant hyperthermia resulting from inhaled anesthetics and succinylcholine is believed to have a genetic incidence of only about 1 in 2000 people.

    Two hundred and four patients who underwent renal transplantation were followed up as outpatients with a minimum of four years. They were divided into two socio-economic levels: group I - 104 patients who underwent transplantation in a private hospital and 120 patients (group II) with a lower socio-economic standard, treated in a public hospital. In both groups urinary infections and hepatitis were excluded. The incidence of infection in group I was 24% and in group II, 50% (p = 0.0002). There was no difference in relation to viral infection in either groups. However, bacterial infection and infection by opportunistic agents were significantly higher in group II (p = 0.0001 and p = 0.0282). The number of hospitalizations and the number of infections of patients were higher in group II. There was a tendency for an increase in mortality owing to infection in group II. There was no difference in the two groups as the parameters of: age, sex, type of donor, primary disease, number of rejections crises, level of serum creatinine and number of patients with ciclosporine. On the other hand, the dose of azathioprine and prednisone was mildly higher in those patients of group II. Low level of socio-economic conditions is a risk factor in renal transplant patients.

    An important component of safety assessment of new pharmaceuticals is evaluation of their potential to increase the risk of developing cancer in humans. The traditional 2-year rodent bioassay often is not feasible or scientifically applicable for evaluation of biotherapeutics. Additionally, it has poor predictive value for non-genotoxic immunosuppressive compounds. Thus, there is a need for alternative testing strategies. A novel 3-stage tumor model in syngeneic C3H/HeN mice was evaluated here to study the effects of immunosuppressive drugs on tumor promotion and progression in vivo. The model employed a skin squamous cell carcinoma cell line (SCC VII) due to the increased prevalence of squamous cell carcinoma (SCC) in humans associated with immunosuppression after transplants. Local invasion, colonization and tumor progression were evaluated. The validation set of immunosuppressive drugs included: Cyclosporin (CSA), cyclophosphamide (CTX), azathioprine, etanercept, abatacept and prednisone. Local invasion was evaluated by histological assessment as well as fluorescence trafficking from Qdot(®)-labeled tumor cells from the site of inoculation to the draining lymph node. Colonization was evaluated by lung colony counts following intravenous inoculation. Tumor progression was assessed by morphometric analysis of lesion area, angiogenesis and growth fraction of established metastatic neoplasia. Immunosuppressive drugs in the validation set yielded mixed results, including decreased progression. The methods and results described herein using an in vivo syngeneic mouse tumor model can provide insight about the assessment of immunosuppressive drugs in carcinogenicity risk assessment.

    Full Text Available Activated granulocytes, monocytes, and platelets appear to be closely involved in active Crohn’s disease (CD. Adsorptive granulocyte apheresis (GCAP is a new treatment for inflammatory bowel disease. GCAP was used to treat a 23-year-old female patient with CD resistant to both infliximab (IFX and azathioprine (AZA. At 16 years of age, the patient underwent a partial ileal resection for peritonitis caused by perforative ileitis. On pathological examination of the resected specimen, the diagnosis was CD. Mesalazine was started, but the patient did not comply with therapy. She was admitted to our hospital again in 2007 due to an acute exacerbation. IFX induction therapy was started. The combination of both AZA daily and IFX every 8 weeks was continued as maintenance therapy. However, she developed severe abdominal pain in September 2009. Computed tomography revealed ileitis and ascending colitis, and blood tests showed high inflammatory response marker levels. She was considered to have IFX- and AZA-resistant CD. Initial intravenous steroid therapy did not result in any improvement. Therefore, weekly GCAP therapy was given for 5 weeks, which immediately improved the inflammatory response markers. GCAP combined with prednisolone could be effective for IFX- and AZA-refractory CD.

    Total lymphoid irradiation (TLI) was administered to 11 patients who had intractable rheumatoid arthritis that was unresponsive to conventional medical therapy, including aspirin, multiple nonsteroidal antiinflammatory drugs, gold salts, and D-penicillamine. Total lymphoid irradiation was given as an alternative to cytotoxic drugs such as azathioprine and cyclophosphamide. After radiotherapy, 9 of the 11 patients showed a marked improvement in clinical disease activity as measured by morning stiffness, joint tenderness, joint swelling, and overall functional abilities. The mean improvement of disease activity in all patients ranged from 40-70 percent and has persisted throughout a 13-28 month followup period. This improvement permitted the mean daily steroid dose to be reduced by 54%. Complications included severe fatigue and other constitutional symptoms during radiotherapy, development of Felty's syndrome in 1 patient, and an exacerbation of rheumatoid lung disease in another. After therapy, all patients exhibited a profound T lymphocytopenia, and a reversal in their T suppressor/cytotoxic cell to helper cell ratio. The proliferative responses of peripheral blood mononuclear cells to phytohemagglutinin, concanavalin A, and allogeneic leukocytes (mixed leukocyte reaction) were markedly reduced, as was in vitro immunoglobulin synthesis after stimulation with pokeweed mitogen. Alterations in T cell numbers and function persisted during the entire followup period, except that the mixed leukocyte reaction showed a tendency to return to normal values.

    Full Text Available Systemic sclerosis (SSc is an autoimmune systemic disease of unknown etiology. Present treatment modalities have limited impact on clinical/ laboratory outcomes. For the first time in our center, we used plasma exchange (PEx in a rather young woman with recent onset but progressive SSc. She is a 39-year-old woman with a recent history of skin stiffness, Raynaud’s phenomenon, nail fold capillary changes and newly diagnosis of SSc presented to us due to worsening her clinical symptoms even after initiation of routine remedies such as low dose oral prednisolone, Ca-channel blockers, azathioprine and pentoxyfylline. After obtaining written consent, interdisciplinary discussion with experts in this field and agreement we started a series of plasma exchange with FFP replacement for her. A dramatic clinical response was observed in respect to Raynaud’s phenomenon, skin stiffness, tendon rub after three sessions of PEx. Her modified Rodnan skin score (MRSS dropped from 36 (before commencement of therapy to 28 in day 4 and 18 in day 20 after 15 sessions of PEx. In conclusion PEx could significantly modify the course of SSc as observed in our case study. Elimination of culprit immune mediators/cytokines/autoantibodies could be the possible mechanism of action of PEx.

    2016-01-01

    Aim: The aim of this study was to review our experience with gestations in autoimmune hepatitis patients. Background: There are only limited data describing pregnancy in patients with autoimmune hepatitis. Patients and methods: Retrospective analysis of pregnancies with autoimmune hepatitis followed in Centro Hospitalar do Porto, Portugal in the last ten years. Results: We reported nine pregnancies in seven patients with autoimmune hepatitis. Two patients had documented liver cirrhosis prior to the pregnancy. In this study, 66.7% of patients were treated with azathioprine and 88.9% with prednisolone. Clinical improvements were observed in 11.1% of pregnancies and 22.2% exacerbations were diagnosed. There were six live births and two preterm deliveries (preterm delivery rate of 33%). We also report three first trimester miscarriages (early gestation miscarriage rate of 33%). There were no neonatal or maternal deaths. Conclusion: The favorable obstetric outcome is a realistic expectation in patients with autoimmune hepatitis. Tight monitoring and control of asymptomatic and unpredictable exacerbations, which are unrelated to the severity of the underlying disease, are essential to the prognosis of the current pregnancy.

    Cristina Candido

    Full Text Available Abstract Introduction: Women regain fertility a few time after renal transplantation. However, viability of pregnancy and maternal complications are still unclear. Objective: To describe the outcomes of pregnancies in kidney transplanted patients, focusing on maternal complications. Methods: Retrospective study of pregnancies in kidney transplanted patients between 2004 and 2014, followed up 12 months after delivery. Each pregnancy was considered an event. Results: There were 53 pregnancies in 36 patients. Mean age was 28 ± 5years. Pregnancy occurred 4.4 ± 3.0 years post-transplant. Immunosuppression before conception was tacrolimus, azathioprine, and prednisone in 74% of the cases. There were 15% miscarriages in the 1st trimester and 8% in 2nd trimester. In 41% of the cases, it was necessary to induce labor. From all births, 22% were premature and 17% very premature. There were 5% stillbirths and 5% of neonatal deaths. De novo proteinuria occurred in 60%, urinary tract infection in 23%, preeclampsia in 11%, acute rejection in 6%, and graft loss in 2% of the cases. It was observed a significant increase in creatinine at preconception comparing to 3rd trimester and follow-up (1.17 vs. 1.46 vs. 1.59 mg/dL, p < 0.001. Conclusion: Although the sample is limited, the number of miscarriages was higher than in the general population, with high rates of maternal complications. Sustained increase of creatinine suggests increased risk of graft loss in long-term.

    Management of inflammatory bowel disease includes not only drug, endoscopic and surgical therapy but alsopsychosocial support, dietary and specific nutritional measures: a multidisciplinary medical, surgical, nursingand dietetic approach is essential for all patients, particularly those with complex or refractory disease. Inthis paper, current treatment of acute severe ulcerative colitis and steroid-refractory or -dependent Crohn'sdisease is reviewed. Adjunctive intravenous cyclosporin is an alternative to urgent colectomy in steroid-refractory patients with acute severe ulcerative colitis, while the place of intravenous heparin for thisindication awaits clarification. Azathioprine or 6-mercaptopurine are useful options in chronically active,steroid-refractory or -dependent Crohn's disease, but may take up to 4 months to work. Methotrexate is amore recent immunomodulatory alternative. Of new therapies selectively aimed at specific pathophysiologicaltargets, the first to reach clinical application is anti-TNF-alpha antibody (infliximab) for refractory Crohn'sdisease: its benefits are promising, but experience with it is limited to date, its cost is high and there areuncertainties about long-term safety. In view of the increasing variety and complexity of management optionsin inflammatory bowel disease, whether apparently responsive or difficult to treat, patients must participatein decisions about which therapies they are to be given.

    1975-01-01

    Results are presented on the effect of immunosuppressive substances such as chlorambucil, cyclophosphamide, azathioprine, amethopterine and a cortizone derivate of betamethasone, on the development of Fasciola hepatica in the rat. The suppression of the immune response of the host to immunosuppressants was reflected in an earlier start of migration of the flukes to the common bile duct, and in an earlier onset of egg production as compared with that in the controls. Of the substances employed, cyclophosphamide and betamethasone were the most effective ones within the period from week 2--6 p.i., which is the time during which the migration of the flukes in the liver parenchyma is highest. Pathological changes in the liver of the animals were less marked than those of the infected controls. Evidence was obtained on an increased pathogenicity of infective larval flukes causing a higher mortality of the hosts in comparison with that of the control animals. On the other hand, the administration of immunosuppressants did neither influence the total number of developed flukes nor the appearance of eosinophilia in the peripheral blood of the treated animals.

    Intact or inactivated donor lymphoid cells have been found to downregulate the alloimmune response in a number of experimental models. We conducted a randomized, prospective, double blind, and placebo-controlled trial to determine whether heat-treated donor spleen cells would affect early rejection after liver transplantation. Donor spleen was obtained during organ procurement for 40 patients undergoing liver transplantation. All patients were treated with cyclosporine, azathioprine and steroids. The patients were randomized after surgery to receive either heat-treated (45 degrees C for 1 h) spleen cells or placebo. Patients underwent protocol biopsies at 1 wk, 4 and 12 months, or as needed. Biopsies were reviewed in a blind fashion and scored according to the Banff consensus criteria. Randomization resulted in 19 patients in the spleen cell group and 21 in the placebo group. One-yr graft survival was 94 and 100%, respectively. Early rejection was more frequent in the spleen cell group (61 vs. 35%, p, not significant). The histopathological rejection activity index at 7 d was also higher for the patients in the spleen cell group: 39% of spleen cell treated patients had a score of 4 or higher as opposed to 5% in the placebo group (p spleen cell group versus 1.3 + 1.7 for the placebo group (p = 0.034). It is concluded that heat-treated donor spleen cells given within 24 h after liver transplantation were not clinically beneficial and increased the intensity of rejection in 7-d protocol liver biopsies.

    Full Text Available Glucocorticosteroids (GCs that provide a good and rapid clinical effect are the drug of choice to treat rheumatic polymyalgia (RP. A review of English language publications on the treatment of RP is given. Thirty (13 randomized and 17 observational studies of 20 and more patients with RP have been analyzed. Particular emphasis is laid on initial therapy with GCs, evaluation of their different daily doses, schemes for their dosage reduction and treatment termination, and on the frequency of recurrences. Studies dealing with the treatment with prednisone, prednisolone, methylprednisolone, and injectable sustained-release GC formulations are considered. The data of clinical trials of glucocorticoid-sparing agents (methotrexate, azathioprine during early and maintenance therapy are analyzed. The genetically engineered agents (infliximab, etanercept investigated in clinical trials are considered to be as alternatives; a case of using rituximab is described. The role of nonsteroidal anti-inflammatory drugs in the treatment of RP is also evaluated. An algorithm is proposed for the management of a patient with RP.

    Full Text Available Abstract Introduction We report a case of bilateral herpetic keratitis developing after rapid oral corticosteroid tapering in a patient with pemphigus foliaceus, which was followed by unilateral neurotrophic keratitis that was treated with amniotic membrane transplantation. Case presentation A 71-year-old Korean man developed bilateral herpetic keratitis one week after rapid tapering of systemic corticosteroid. He had been on high-dose oral corticosteroid and azathioprine therapy for six months for treatment of pemphigus foliaceus. Topical acyclovir ointment was prescribed. A week later, our patient's right eye had healed, but his left eye showed increased stromal edema with enlarged epithelial defects. He was prescribed oral acyclovir with topical broad-spectrum antibiotics applied to his left eye. The stromal edema cleared within a week but the epithelial defect remained unchanged. An amniotic membrane transplantation was performed on our patient's left eye, and his epithelial defect had totally healed three weeks later. Conclusions Patients with autoimmune disease or who are on immunosuppressive therapy have a higher chance of developing bilateral herpetic keratitis. Although rare, the condition may be followed by unilateral neurotrophic keratitis. Rapid corticosteroid tapering may act as a triggering factor for viral infection or reactivation of herpes.

  2. Myasthenia gravis: subgroup classification and therapeutic strategies.

    Gilhus, Nils Erik; Verschuuren, Jan J

    2015-10-01

    Myasthenia gravis is an autoimmune disease that is characterised by muscle weakness and fatigue, is B-cell mediated, and is associated with antibodies directed against the acetylcholine receptor, muscle-specific kinase (MUSK), lipoprotein-related protein 4 (LRP4), or agrin in the postsynaptic membrane at the neuromuscular junction. Patients with myasthenia gravis should be classified into subgroups to help with therapeutic decisions and prognosis. Subgroups based on serum antibodies and clinical features include early-onset, late-onset, thymoma, MUSK, LRP4, antibody-negative, and ocular forms of myasthenia gravis. Agrin-associated myasthenia gravis might emerge as a new entity. The prognosis is good with optimum symptomatic, immunosuppressive, and supportive treatment. Pyridostigmine is the preferred symptomatic treatment, and for patients who do not adequately respond to symptomatic therapy, corticosteroids, azathioprine, and thymectomy are first-line immunosuppressive treatments. Additional immunomodulatory drugs are emerging, but therapeutic decisions are hampered by the scarcity of controlled studies. Long-term drug treatment is essential for most patients and must be tailored to the particular form of myasthenia gravis.

    Inflammatory bowel disease (IBD) is most common in young adults, but it can also present in the elderly. Furthermore, with the aging of the population, the number of elderly patients with IBD is expected to grow. Other conditions, such as diverticulitis and ischaemic colitis, may be more common in the elderly and need to be considered in the differential diagnosis. Management of elderly patients with IBD follows the same principles as in younger patients, with a few exceptions. For patients with mild-to-moderate colitis, a 5-aminosalicylate drug is often used (sulfasalazine, olsalazine, mesalazine, balsalazide). Topical therapy may be sufficient for those with distal colitis, whereas an oral preparation is used for more extensive disease. In those with more severe or refractory symptoms, corticosteroids are used, although the elderly appear to be at increased risk for corticosteroid-associated complications. For patients with corticosteroid-dependent or corticosteroid-refractory disease, immunosuppression with azathioprine or mercaptopurine may help avoid surgery. In patients with Crohn's disease, a similar approach is followed, with the additional consideration that the formulation of drug used must ensure delivery of drug to the site of inflammation. In fistulising Crohn's disease, antibacterials, immunosuppressive drugs, infliximab and surgery are often used in combination. Controlled trials and clinical experience have shown that infliximab is a significant addition to the therapeutic armamentarium for patients with Crohn's disease.

    Various types of virus induced and non-virus induced chronic active hepatitis (CAH) as well as chronic non-suppurative destructive cholangitis (PBC) and primary sclerosing cholangitis have to be distinguished. Classical autoimmune type "lupoid" CAH is characterized by antinuclear antibodies (ANA), liver membrane antibodies (LMA) and smooth muscle antibodies (SMA). A second subgroup of autoimmune type CAH is characterized by anti liver kidney-microsomal antibodies (LKM) which are directed against a specific cytochrome p-450 isoenzyme. A third subgroup of autoimmune type CAH is identified by auto-antibodies to a soluble cytoplasmic liver antigen (SLA). Autoimmune type CAH profits from immuno-suppressive therapy, i.e. corticosteroids alone or in combination with azathioprin. Chronic hepatitis B virus infection is nowadays treated with Interferon when HBV-DNA is detectable in serum, duration of liver disease is less than 5 years and superinfection with HDV and HIV can be excluded. PBC is diagnosed through the detection of antimitochondrial antibodies (AMA) and its PBC specific subtypes anti p 62 (M2) and anti p 48. Aetiology and pathogenesis of PBC are still unknown. Liver transplantation is an established therapy for endstage PBC. This is also true for primary sclerosing cholangitis (PSC).

    Full Text Available Die Neuromyelitis optica (NMO ist eine schubförmige demyelinisierende Erkrankung des Zentralnervensystems mit vornehmlichem Befall von Sehnerven und Rückenmark. Sie ist bis vor einigen Jahren für eine Sonderform der Multiplen Sklerose (MS gehalten worden. Die Entdeckung eines NMO-spezifischen Autoantikörpers, der mit Aquaporin-4, dem Wasserkanal der Astrozytenzellmembran reagiert und eine bedeutende Rolle in der Pathogenese dieser seltenen Erkrankung spielt, hat dazu geführt, dass die NMO nun als eigene Krankheitsentität gesehen wird. Akute Krankheitsschübe der NMO werden analog zu Exazerbationen der MS mit hochdosiertem, i.v. verabreichtem Methylprednisolon behandelt. Bei fehlender therapeutischer Wirksamkeit wird eine Plasmapherese angeschlossen. Zur Vorbeugung weiterer Krankheitsschübe werden im Unterschied zur MS nicht immunmodulierende, sondern immunsuppressive Medikamente eingesetzt. Als Mittel der Wahl gelten derzeit eine orale Langzeittherapie mit Prednisolon und Azathioprin, Mycophenolat-Mofetil oder i.v. Rituximab. Diese Empfehlungen stehen in Einklang mit den derzeitigen Vorstellungen zur Pathogenese der NMO. Sie stützen sich allerdings nur auf kleine klinische Studien mit geringen Fallzahlen ohne hohe Evidenzklasse.

    Full Text Available Abstract Background One of the rare presentations of superior vena cava syndrome is bleeding of "downhill" esophageal varices (DEV and different approaches have been used to control it. This is a case report whose DEV was eradicated by band ligation for the first time. Case presentation We report a 42-year-old man who is a known case of Behcet's disease. The patient's first presentation was superior vena cava syndrome due to thrombosis followed by bipolar ulcers and arthralgia. He received warfarin, prednisolone and azathioprine. The clinical course of the patient was complicated by one episode of hematemesis without abdominal pain when the patient's PT was in therapeutic range. After resuscitation and correction of PT with fresh frozen plasma transfusion, upper gastrointestinal endoscopy was done. Prominent varices were seen in the upper third of the esophagus, tapering to the middle part without acute bleeding. Stomach and duodenum were normal. Color ultrasonography evaluation of the portal, hepatic and splenic veins was negative for thrombosis. Band ligation was done and the patient's bleeding did not recur. Conclusion Band ligation is a safe and effective method for controlling DEV bleeding in patients with uncorrectable underlying disorders.

    Granulomatosis with polyangiitis and microscopic polyangiitis are small vessel vasculitides characterized by circulating antineutrophil circulating antibodies. Standard treatment for active severe disease has consisted of cyclophosphamide with glucocorticoids with or without plasmapheresis, which achieves approximately 75% sustained remission, but carries significant adverse effects such as malignancy, infertility, leukopenia, and infections. The role of B cells in the pathogenesis of anti-neutrophil circulating antibodies-associated vasculitis has been established, and as such, rituximab, a monoclonal anti-CD20 antibody, has been studied in treatment of active granulomatosis with polyangiitis and microscopic polyangiitis (induction) and in maintaining remission. Rituximab has been shown to be effective in inducing remission in several retrospective studies in patients with refractory disease or cyclophosphamide intolerance. The RAVE and RITUXVAS trials demonstrated rituximab is a noninferior alternative to standard cyclophosphamide-based therapy; however, its role in elderly patients and patients with severe renal disease warrants further investigation. Rituximab has been compared with azathioprine for maintaining remission in the MAINRITSAN trial and may be more efficacious in maintaining remission in patients treated with cyclophosphamide induction. Rituximab is not without risks and carries a similar adverse event risk rate as cyclophosphamide in randomized control trials. However, its use can be considered over cyclophosphamide in patients who have relapsing or refractory disease or in young patients seeking to preserve fertility.

    Misconceptions are common in the care of patients with inflammatory bowel disease (IBD). In this paper, we state the most commonly found misconceptions in clinical practice and deal with the use of 5-aminosalicylates and thiopurines, to review the related scientific evidence, and make appropriate recommendations. Prevention of errors needs knowledge to avoid making such errors through ignorance. However, the amount of knowledge is increasing so quickly that one new danger is an overabundance of information. IBD is a model of a very complex disease and our goal with this review is to summarize the key evidence for the most common daily clinical problems. With regard to the use of 5-aminosalicylates, the best practice may to be consider abandoning the use of these drugs in patients with small bowel Crohn' s disease. The combined approach with oral plus topical 5-aminosalicylates should be the first-line therapy in patients with active ulcerative colitis; once-daily treatment should be offered as a first choice regimen due to its better compliance and higher efficacy. With regard to thiopurines, they seem to be as effective in ulcerative colitis as in Crohn' s disease. Underdosing of thiopurines is a form of undertreatment. Thiopurines should probably be continued indefinitely because their withdrawal is associated with a high risk of relapse. Mercaptopurine is a safe alternative in patients with digestive intolerance or hepatotoxicity due to azathioprine. Finally, thiopurine methyltransferase (TPMT) screening cannot substitute for regular monitoring because the majority of cases of myelotoxicity are not TPMT-related.

  9. Challenges for lupus management in emerging countries.

    In emerging countries, systemic lupus erythematosus (SLE) has been associated with several unfavorable outcomes including disease activity, damage accrual, work disability and mortality. Poor socioeconomic status (SES) and lack of access to healthcare, especially in medically underserved communities, may be responsible for many of the observed disparities. Diagnostic delay of SLE or for severe organ damages (renal involvement) have a negative impact on those adverse outcomes in lupus patients who either belong to minority groups or live in emerging countries. Longitudinal and observational prospective studies and registries may help to identify the factors that influence poor SLE outcomes in emerging countries. Infection is an important cause of mortality and morbidity in SLE, particularly in low SES patients and tuberculosis appears to be frequent in SLE patients living in endemic areas (mainly emerging countries). Thus, tuberculosis screening should be systematically performed and prophylaxis discussed for patients from these areas. SLE treatment in the developing world is restricted by the availability and cost of some immunosuppressive drugs. Moreover, poor adherence has been associated to bad outcomes in lupus patients with a higher risk of flares, morbidity, hospitalization, and poor renal prognosis. Low education and the lack of money are identified as the main barrier to improve lupus prognosis. Newer therapeutic agents and new protocols had contributed to improve survival in SLE. The use of corticoid-sparing agents (hydroxychloroquine, methotrexate, azathioprine and mycophenolate mofetif) is one of the most useful strategy; availability of inexpensive generics may help to optimize access to these medications.

    Full Text Available Background and Aims. Thiopurines are used in the treatment of Crohn’s disease (CD and thiopurine S-methyltransferase (TPMT activity can guide thiopurine dosing to avoid adverse events. This retrospective study evaluated the safety and efficacy of starting thiopurines at low dose versus full dose in patients with CD and normal TPMT. Methods. This was a single center retrospective study including adult CD patients with normal TPMT levels (≥25 nmol/hr/g Hgb who were followed for 1 year. Patients started at full dose of azathioprine (2–2.5 mg/kg or 6-mercaptopurine (1–1.5 mg/kg were compared to patients started at low dose. Harvey-Bradshaw index, treatment failure, and drug-related adverse events were recorded. Results. Our study included 134 patients. Both groups had similar incidences of drug-related adverse events and discontinuation of therapy due to side effects. Fifty-six percent of all adverse events occurred within 31 days and 92% occurred within 3 months of therapy. Clinical response favored the full-dose group at 6 months (69% versus 27%, p=0.0542. Conclusions. Our study indicates that it is safe to start patients on full-dose thiopurine when they have a normal TPMT given its very similar toxicity profile to patients started on low dose. This may also positively impact efficacy.

    Full Text Available OBJECTIVE: To assess intermediate-term outcome in children who have undergone orthotopic heart transplantation. METHODS: We carried out a longitudinal and prospective study between October '92 and June '99 comprising 20 patients with ages ranging from 12 days to 7 years (mean of 2.8 years. We employed a double immunosuppression protocol with cyclosporine and azathioprine and induction therapy with polyclonal antithymocyte serum. Survival and complications resulting from the immunosuppression protocol were analyzed. RESULTS:The double immunosuppression protocol and the induction therapy with polyclonal antithymocyte serum resulted in an actuarial survival curve of 90% and 78.2% at 1 and 6 years, respectively, with a mean follow-up period of 3.6 years. One patient died due to acute rejection 40 days after transplantation; another patient died 2 years after transplantation due to lymphoproliferative disorder; a third patient died because of primary failure of the graft; and a fourth patient died due to bronchopneumonia. The major complications were as follows: acute rejection, infection, nephrotoxicity, and systemic hypertension. The means of rejection and infection episodes per patient were 2.9 and 3.4, respectively. After one year of transplantation, a slight reduction in the creatinine clearance and systemic hypertension were observed in 7 (38.9% patients. CONCLUSION: Heart transplantation made life possible for those patients with complex congenital heart diseases and cardiomyopathies in refractory congestive heart failure constituting a therapeutical option for this group of patients in the terminal phase.

    2016-01-01

    Takayasu arteritis (TA) is the third most common childhood vasculitis and its clinical manifestations depend on the arteries involved. We report a case of a 9-year-old boy with multiple aneurysms in carotid and iliac arteries, subclavian and coronary arteries, and abdominal aorta. At the age of 7 years, he presented with recurrent fever and hepatosplenomegaly. An angio-computed tomography scan showed aneurysms in the left subclavian artery, abdominal aorta, and both proximal iliac arteries. He was diagnosed with TA and was treated with corticosteroids, aspirin, and enalapril. One year later, he was admitted to Dr Roberto Gilbert Children’s Hospital because of intracranial hemorrhage. Angiography revealed enlargement of aneurysms enlargement and new aneurysms. He also developed portal hypertension. Treatment with intravenous corticosteroids, azathioprine, and monthly intravenous cyclophosphamide was begun. After 6 months of no improvement, infliximab was begun. The aim of this article was to report the concurrence of coronary involvement and portal vein hypertension in pediatric TA because there were scarce reports on this matter. PMID:27895519

    A 46-year-old man who had been treated with azathioprine and budesonide for Crohn's disease for the past eight years developed a purulent skin condition on the right ring finger. Despite surgical drainage and treatment with amoxicillin and flucloxacillin, the condition spread itself over the hand and lower arm, partly per continuum and partly in jumps. The patient did not feel ill and there were no systemic symptoms. Ultimately, Nocardia asteroides was cultured from the wound and complete cure was achieved after 8 months' treatment with co-trimoxazole. Infections with Nocardia spp. are rare but may occur more often and run a more fulminant course in patients under treatment with immunosuppressants. Cutaneous nocardiosis generally has a characteristic lymphogenous spreading pattern, but an atypical picture with pustules, pyoderma, cellulitis or abscess formation is also possible. In non-cutaneous nocardiosis there is usually pneumonia or lung abscess, possibly with secondary haematogenous spread to the central nervous system or skin. Culturing Nocardia requires more time than usual but can be promoted by special culture media. Treatment of the infection with co-trimoxazole is the method of choice and is almost always successful in cases of cutaneous nocardiosis.

    AIM: To assess the efficacy of intravenous cyclophosphamide pulse therapy for refractory inflammatory bowel disease (IBD).METHODS: We included in our cohort eight patients with (moderate/severe) steroid refractory IBD (4 with ulcerative colitis and 4 with Crohn's disease). They all received 6 cycles of intravenous cyclophosphamide (800mg) per month.RESULTS: Patients entered into remission after the second/third cyclophosphamide pulse. Disease activity decreased. There were no side effects and toxicity. All the patients went into long lasting remission. All Crohn's disease patients and 3 of 4 ulcerative colitis patients achieved complete remission. One patient with ulcerative colitis showed an impressive clinical response but did not enter into remission. For the maintenance, patients with Crohn's disease were treated with methotrexate (15 mg/wk) and patients with ulcerative colitis were treated with azathioprine (2.5 mg/kg body weight/d).CONCLUSION: Remission was maintained in all patients for 6 mo on the average. The drug was well tolerated. These findings suggest that aggressive immunosuppressive therapy may be useful in some refractory patients and further controlled study should be considered in order to fully evaluate this type of treatment as a potential therapy for IBD.

    Crohn's disease (CD) is a multifactorial disorder of unknown cause. Outstanding progress regarding the pathophysiology of CD has led to the development of innovative therapeutic concepts. Numerous controlled trials have been performed in CD over the last years. However, many drugs have not been approved by regulatory authorities due to lack of efficacy or severe side effects. Therefore, well-known drugs, including 5-ASA, systemic or topical corticosteroids, and immunosuppressants such as azathioprine, are still the mainstay of CD therapy. Importantly, biologicals such as infliximab have shown to be efficacious in problematic settings such as fistulizing or steroid-dependent CD. This review is intended to give practical guidelines to clinicians for the conventional treatment of CD. We concentrated on the results of randomized, placebo-controlled trials and meta-analyses, when available, that provide the highest degree of evidence. We provide evidence-based treatment algorithms whenever possible. However, many clinical situations have not been answered by controlled clinical trials and it is important to fill these gaps through expert opinions. We hope that this review offers a useful tool for clinicians in the challenging treatment of CD.

    Crohn's disease (CD) and ulcerative colitis (UC) are chronic inflammatory diseases of the gastrointestinal tract. While a cure remains elusive, both can be treated with medications that induce and maintain remission. With the recent advent of therapies that inhibit tumor necrosis factor (TNF) alpha the overlap in medical therapies for UC and CD has become greater. Although 5-ASA agents have been a mainstay in the treatment of both CD and UC, the data for their efficacy in patients with CD, particularly as maintenance therapy, are equivocal. Antibiotics may have a limited role in the treatment of colonic CD. Steroids continue to be the first choice to treat active disease not responsive to other more conservative therapy; nonsystemic steroids such as oral and rectal budesonide for ileal and right-sided CD and distal UC respectively are also effective in mild-rnederate disease. 6-mercaptopurine (6-MP) and its prodrug azathioprine are steroid-sparing immunomodulators effective in the maintenance of remission of both CD and UC, while methotrexate may be used in both induction and maintenance of CD. Infliximab and adalimumab are anti-TNF agents approved in the US and Europe for the treatment of Crohn's disease, and infliximab is also approved for the treatment of UC.

    Corticosteroids and immunomodulators have been the mainstay therapies for Crohn's disease. Corticosteroids are highly effective to control symptoms in the shortterm, but they are not effective in maintaining remission, they heal the mucosa in a reduced proportion of cases, and long-time exposure is associated with an increased risk of infections and mortality. Immunomodulators, azathioprine and methotrexate, heal the mucosa in a higher proportion of patients that corticosteroids but their onset of action is slow and they benefit less than half of patients with Crohn's disease. In the last decade, medical therapy for Crohn's disease has experienced a remarkable change due to the introduction of biologic therapy, and particularly the use of anti-tumour necrosis factor-alpha agents. Infliximab, adalimumab, and certolizumab pegol have demonstrated efficacy for induction and maintenance of remission in active Crohn's disease. These agents have raised the bar for what is a suitable symptomatic response in Crohn's disease and modification of the natural history of the disease has become a major goal in the treatment of Crohn's disease. There are several data in the literature that suggest that early use of biologic therapy and achievement of mucosal healing contribute to disease course modification. However, many questions on early biological therapy for Crohn's disease remain still unanswered.

    2009-01-01

    Full Text Available Mizoribine (MZB is an imidazole nucleoside and an immunosuppressive agent. The immunosuppressive effect of MZB has been reported to be due to the inhibition of DNA synthesis in the S phase of the cell cycle. Because of its relative lack of toxicity, during the past decade MZB has been frequently used instead of azathioprine as a component of immunosuppressive drug regimens. MZB is being used to treat renal transplantation patients, IgA nephropathy, lupus erythematosus, and childhood nephrotic syndrome (NS, and some recent studies have assessed the efficacy of oral MZB pulse therapy for severe lupus nephritis, steroid-resistant NS, and frequently relapsing-steroid-dependent NS. This review summarizes the published findings on the efficacy of MZB for renal disease including IgA nephropathy, lupus nephritis, and NS, as well as of oral MZB pulse therapy for severe lupus nephritis and NS, and also the mechanism of the effect of oral MZB pulse therapy on the lymphocyte cell cycle.

    Full Text Available Behcet's disease (BD is an inflammatory multisystemic disease characterized by perivascular inflammation and generally presents with recurrent oral and genital ulcers and uveitis. It is known that BD may also involve the kidneys. Amyloidosis, glomerulonephritis (crescentic, proliferative, IgA nephropathy, interstitial nephritis are commonly described renal lesions which may lead to end-stage renal disease (ESRD in BD. Immunosuppressive therapies used for the treatment of BD may cause malignant diseases (lymphoma, skin and solid organ malignancies, etc. The risk with azathioprin is especially high after 10 years of treatment. Cyclosporine, another immunosuppressive agent frequently used for treatment of BD, also has tumorigenic potential and is associated with renal toxicity and renal failure. Renal transplantation may be performed in patients with malignancies after a 2-5 year complete remission period, although it may differ according to the type of tumor. We report a case of end-stage renal disease and Hodgkin's lymphoma occurring after treatment with immunosuppressive medicine for BD. The patient was successfully treated with renal transplantation.

    Full Text Available Celiac disease is an autoimmune disorder primarily targeting the small bowel, although extraintestinal extensions have been reported. The autoimmune processes can affect the liver with manifestations such as primary biliary cirrhosis and autoimmune hepatitis. We describe a 61-year-old woman with celiac disease and an increased levels of aminotransferases. The persistence of increased levels of aminotransferases after 1 year of gluten-free diet and the positivity for an anti-nuclear and anti-double-strand DNA antibodies led to a misdiagnosis of systemic lupus erythematosus-related hepatitis. Based on these findings the patient was placed on steroids, which after a few months were stopped because of the onset of diabetes mellitus. Soon after steroid withdrawal, the patient had a marked increase in aminotransferases and γ-globulins, and a liver biopsy revealed chronic active hepatitis. A course of three months of steroids and azathioprine normalized both biochemical and clinical parameters. Currently the patient is symptom-free and doing well. In conclusion, a hypertransaminasemia persisting after a gluten-free diet should be interpreted as a sign of coexisting autoimmune liver disease. Any autoantibody positivity (in this case to ANA and anti-dsDNA should be carefully considered in order to avoid misdiagnosis delaying appropriate clinical management.

    Ten patients with lupus nephritis and marked proteinuria (3.9 g or more/d) that did not respond adequately to treatment with prednisone alone or prednisone in combination with azathioprine were treated with total lymphoid irradiation in an uncontrolled feasibility study. Within 6 weeks after the start of total lymphoid irradiation, the serum albumin level rose in all patients in association with a reduction in the serum level of anti-DNA antibodies, an increase in the serum complement level, or both. Improvement in these variables persisted in eight patients followed for more than 1 year, with the stabilization or reduction of the serum creatinine level. Urinary leakage of albumin was substantially reduced in all patients. Side effects associated with radiotherapy included transient constitutional complaints in ten patients, transient blood element depressions in three, localized viral and bacterial infections in four, and ovarian failure in one. The results suggest that total lymphoid irradiation may provide an alternative to cytotoxic drugs in the treatment of lupus nephritis.

    2012-02-01

    BACKGROUND: We assess our long-term experience with regards the safety and efficacy of Mycophenolate Mofetil (MMF) in our low risk renal transplant population and compared it retrospectively to Azathioprine (AZA) immunosuppressive regimen. Patients and methods. Between January 1999 and December 2005, 240 renal transplants received MMF as part of their immunosuppressive protocol (MMF group). AZA group of 135 renal transplants was included for comparative analysis (AZA group). Patients received Cyclosporine was excluded from this study. RESULTS: The incidence of biopsy proven 3-month acute rejections was 30 (12.5%) in MMF group and 22 (16%) in AZA group respectively (P = 0.307). Patient survival rates at 1 and 5 years for the MMF group were 97 and 94%, respectively, compared to 100% and 91% at 1 and 5 years respectively for the AZA group (P = 0.61). Graft survival rates at 1 and 5 years for the MMF group were 95 and 83%, respectively, compared to 97 and 84% at 1 and 5 years, respectively for the AZA group (P = 0.62). CONCLUSION: There was no difference in acute rejection episodes between MMF and AZA based immunotherapy. Additionally, we observed no significant difference concerning graft survival in the MMF group when compared to AZA group.

    Full Text Available Interstitial lung disease (ILD is common in systemic sclerosis (SSc patients and despite recent advances in the treatment is, at present, the major cause of death. Today, an early diagnosis of ILD is possible, and is mandatory to improve the prognosis of the disease. Pulmonary function tests and high-resolution computed tomography remain the mainstay for the diagnosis of SSc-ILD, but there is a growing interest in lung ultrasound. Recently, the correlation between severity of fibrosis and some peripheral blood biomarkers has been described. Nonselective immunosuppressors are still the main treatment for ILD, with cyclophosphamide (CYC most widely used to obtain remission. Novel therapies towards specific molecular and cellular targets have been suggested; in particular, rituximab (RTX has shown promising results, but further research is needed. It is of paramount importance to define the severity of the disease and the risk of progression in order to define the need for treatment and the treatment intensity. We propose the division of the treatment strategies at our disposal to induce remission into three categories: high intensity (haematopoietic stem cell transplantation, medium intensity (CYC and RTX and low intensity (azathioprine (AZA and mycophenolate mofetil (MMF. After obtaining remission, maintenance treatment with AZA or MMF should be started. In this review we explore new advances in the pathogenesis, diagnosis and treatment of SSc-ILD.

    2009-09-01

    There have been several retrospective studies indicating benefits associated with mycophenalate mofetil (MMF) compared to azathioprine (AZA) for renal transplant recipients. However, these analyses evaluated outcomes prior to changes in utilization patterns of concomitant immunosuppression. Recent prospective trials have indicated similar outcomes among patients treated with MMF and AZA. The aim of this study was to evaluate outcomes in a broad group of patients in the more recent era. We evaluated adult solitary renal transplant recipients from 1998 to 2006 with the national SRTR database. Primary outcomes were time to patient death and graft loss, complications and renal function. Models were adjusted for potential confounding factors, propensity scores and stratified between higher/lower risk transplants and concomitant immunosuppression. Adjusted models indicated a modest risk among AZA patients for graft loss (AHR = 1.14, 95% CI 1.07-1.20); however, this was not apparent among AZA patients also treated with tacrolimus (AHR = 0.97, 95% CI 0.85-1.11]. One-year acute rejection rates were reduced for patients on MMF versus AZA (10 vs. 13%, p MMF with improved outcomes may not be apparent in patients also receiving tacrolimus.

    Full Text Available This paper assessed the burden of adverse events (AEs associated with azathioprine (AZA, cyclophosphamide (CYC, mycophenolate mofetil (MMF, methotrexate (MTX, and cyclosporine (CsA in patients with systemic lupus erythematosus (SLE. Thirty-eight publications were included. Incidence of AEs ranged from 42.8% to 97.3%. Common AEs included infections (2.4–77%, gastrointestinal AEs (3.2–66.7%, and amenorrhea and/or ovarian complications (0–71%. More hematological cytopenias were associated with AZA (14 episodes than MMF (2 episodes. CYC was associated with more infections than MMF (40–77% versus 12.5–32%, resp. or AZA (17–77% versus 11–29%, resp.. Rates of hospitalized infections were similar between MMF and AZA patients, but higher for those taking CYC. There were more gynecological toxicities with CYC than MMF (32–36% versus 3.6–6%, resp. or AZA (32–71% versus 8–18%, resp.. Discontinuation rates due to AEs were 0–44.4% across these medications. In summary, the incidence of AEs associated with SLE immunosuppressants was consistently high as reported in the literature; discontinuations due to these AEs were similar across treatments. Studies on the economic impact of these AEs were sparse and warrant further study. This paper highlights the need for more treatment options with better safety profiles.

  7. Response of transplant recipients to influenza vaccination based on type of immunosuppression: A meta-analysis

    Full Text Available Influenza vaccination is widely used in transplant recipients, but there is little known about the significance and correlating factors of its effectiveness. In the current study, we reviewed the existing literature on clinical trials performed in transplant recipients on the effectiveness of influenza vaccination and to evaluate the relevance of the type of immunosuppression employed in these patients on the humoral reaction to the vaccine. A comprehensive search of the literature was performed through Pubmed and Google Scholar to find reports indicating immunogenicity of influenza vaccination in transplant patients. Finally, data from 15 published clinical trials were included in the meta-analysis. Data of 947 transplant recipients retrieved from 15 clinical trials investigating the immunogenicity of influenza vaccination were analyzed in this meta-analysis. Analysis showed significantly lower rates of sero-conversion among transplant recipients receiving mycophenolate mofetil (MMF than other immunosuppressive agents (relative risk: 0.724; 95% confidence interval: 0.596-0.880; P = 0.001. No significant correlation was found with tacrolimus, sirolimus, cyclosporine and azathioprine. Different immunosuppressive agents seem to have different effects on the humoral response rate to influenza vaccination, with MMF having the most significant deleterious effect. The limited and controversial data available in the literature do not support any differential effect for other immunosuppressive agents.

  8. Current treatment of ulcerative colitis

    2011-01-01

    Ulcerative colitis (UC) is a chronic disease featuring recurrent inflammation of the colonic mucosa. The goal of medical treatment is to rapidly induce a steroid-free remission while at the same time preventing complications of the disease itself and its treatment. The choice of treatment depends on severity, localization and the course of the disease. For proctitis, topical therapy with 5-aminosalicylic acid (5-ASA) compounds is used. More extensive or severe disease should be treated with oral and local 5-ASA compounds and corticosteroids to induce remission. Patients who do not respond to this treatment require hospitalization. Intravenous steroids or, when refractory, calcineurin inhibitors (cyclosporine, tacrolimus), tumor necrosis factor-α antibodies (infliximab) or immunomodulators (azathioprine, 6-mercaptopurine) are then called for. Indications for emergency surgery include refractory toxic megacolon, perforation, and continuous severe colorectal bleeding. Close collaboration between gastroenterologist and surgeon is mandatory in order not to delay surgical therapy when needed.

    Ulcerative colitis (UC) is a chronic disease featuring re- current inflammation of the colonic mucosa. The goal of medical treatment is to rapidly induce a steroid-free remission while at the same time preventing complica- tions of the disease itself and its treatment. The choice of treatment depends on severity, localization and the course of the disease. For proctitis, topical therapy with 5-aminosalicylic acid (5-ASA) compounds is used. More extensive or severe disease should be treated with oral and local 5-ASA compounds and corticosteroids to induce remission. Patients who do not respond to this treatment require hospitalization. Intravenous steroids or, when refractory, calcineurin inhibitors (cyclosporine, tacrolimus), tumor necrosis factor-α antibodies (infliximab) or immunomodulators (azathioprine, 6-mercaptopurine) are then called for. Indications for emergency surgery include refractory toxic megacolon, perforation, and continuous severe colorectal bleeding. Close collaboration between gastroenterologist and surgeon is mandatory in order not to delay surgical therapy when needed. This article is intended to give a general, practice-orientated overview of the key issues in ulcerative colitis treatment. Recommendations are based on published consensus guidelines derived from national and international guidelines on the treatment of ulcerative colitis.

    Full Text Available Granulomatous epiescleritis nodular disease in canines is a very unusual presentation that affects or external fibrous tunic of the eyeball and conjunctiva, which was an increase similar to a unilateral or bilateral tumor. Suspected immune-mediated disease due to lack of identification of an etiologic agent and the response to treatment with immunosuppressive drugs (Couto, 1992. The ideal therapy is the application of steroids via intralesional, topical or systemic, or other immunosuppressants such as cyclosporine and azathioprine; it is still advisable to apply antibiotic is the ideal combination of tetracycline and neomycin (Gilger & Whitley, 1999. The diagnostic method of episcleritis is made by histopathology, which is evident in changes similar to chronic granulomatous inflammation.

    Dermatomyositis is a life-altering inflammatory disorder of skin and muscle. Details regarding the natural course of this disorder, the effects of specific therapies on its progression, and the optimal therapeutic dosage and duration of prednisone are limited. We performed a retrospective medical record review of dermatomyositis patients at four medical centers. All patients were over the age of 21 and had a clinical diagnosis of dermatomyositis with pathological confirmation. We reviewed average muscle strength, corticosteroid use, creatine kinase levels, and supplemental immunosuppressant use during the 36-month period following each patient's initial assessment. One hundred patients participated with an average age of 50.1 years. Average muscle strength improved and prednisone requirements lessened six months after initial assessment. There was no difference in the mean change in muscle strength or cumulative corticosteroid use over 36 months among those initially treated with methotrexate, mycophenolate mofetil, pulse IVIG, or azathioprine. There was a 5% mortality rate in dermatomyositis patients due to infections. Treated dermatomyositis patients demonstrate the most significant improvement in strength during the first six-to-twelve months following their initial clinical assessment. Additional prospective studies are needed to determine the relative benefit of select immunosuppressant agents in preserving strength and reducing corticosteroid use in dermatomyositis.

    Dermatomyositis is a rare idiopathic inflammatory myopathy that affects adults and children, mostly female. Hallmarks of the disease are myositis with necrosis, regeneration and perifascicular atrophy accompanied by a typical skin rash with heliotrope erythema, Gottron's sign, Gottron's papules and nail fold changes with splinter hemorrhage. Typical skin symptoms may appear 6 months up to 2 years before muscle involvement (amyopathic dermatomyositis). New myositis-specific antibodies may allow clinicoserologic correlations within a heterogeneous clinical spectrum. Autoantibody profiles, subtype of myositis, overlap with other collagen vascular disorders and/or malignancy (paraneoplastic dermatomyositis) as well as age of the patients all have a considerable impact on course and prognosis. Infections, drugs and tumors may trigger activation of T and B cells, plasmacytoid dendritic cells, overproduction of type I interferons and complement-mediated endothelial cell damage resulting in vasculopathy. UV radiation may also trigger dermatomyositis. Oral corticosteroids (1.5-2.0 mg/kg body weight/day) are the mainstay of treatment until improvement of muscle symptoms and/or normalization of muscle enzymes with subsequent slow tapering. Corticosteroids may be given as monotherapy or combined with steroid-sparing immunosuppressive agents' i.e. azathioprine, methotrexate, mycophenolate mofetil or high-dose intravenous immunoglobulins. Prognosis has improved considerably since use of high-dose corticosteroids, from 50 to 90% response rate. New therapies with biologicals (anti-CD20-, anti-TNFalpha-, anti-interferon antibodies) and Janus kinase inhibitors are currently being evaluated.

  14. The evidence for immunotherapy in dermatomyositis and polymyositis: a systematic review.

    Dermatomyositis and polymyositis are rare chronic inflammatory disorders with significant associated morbidity and mortality despite treatment. High-dose corticosteroids in addition to other interventions such as immunosuppressants, immunomodulators, and more recently, biologics are commonly used in clinical practice; however, there are no clear guidelines directing their use. Our objective was to systematically review the evidence for immunotherapy in the treatment of dermatomyositis and polymyositis. Relevant studies were identified through Embase and PubMed database searches. Trials were selected using pre-determined selection criteria and then assessed for quality. Randomized controlled trials and experimental studies without true randomization and including adult patients with definite or probable dermatomyositis or polymyositis were evaluated. Any type of immunotherapy was considered. Clinical improvement, judged by assessment of muscle strength after 6 months, was the primary outcome. Secondary outcomes included IMACS definition of improvement, improvements in patient and physician global scores, physical function, and muscle enzymes. Twelve studies met eligibility criteria. Differences in trial design, quality, and variable reporting of baseline characteristics and outcomes made direct comparison impossible. Although no treatment can be recommended on the basis of this review, improved outcomes were demonstrated with a number of agents including methotrexate, azathioprine, ciclosporin, rituximab, and intravenous immunoglobulin. Plasmapheresis and leukapheresis were of no apparent benefit. More high-quality randomized controlled trials are needed to establish the role of immunosuppressive agents in the treatment of these conditions and the clinical context in which they are most likely to be beneficial.

    A small subset of patients with active ulcerative colitis is non-responsive to major known non-biological therapies.We reported 5 patients with positive serum proteinase-3 antineutrophil cytoplasmic antibody (PR3-ANCA) and tried to (1) identify the common clinical features of these patients; (2) investigate the efficacy of a novel therapy using a Chinese medicine compound; and (3) attract more gastroenterologists to be engaged in further study of this subset of patients. The common manifestations of disease in these 5 patients included recurrent bloody diarrhea and inflammatory lesions involving the entire colorectal mucosa. Initial treatment with intravenous methylprednisolone successfully induced remission.Four of these 5 patients were steroid-dependence,and immunosuppressants, such as azathioprine and cyclophosphamide, were ineffective. In 3 patients,only the particular Chinese medicine compound could induce and maintain remission. One patient underwent colectomy. No vascular inflammatory lesions were found by histopathological examination. Although more cases are needed for confirmation, our study indicates that ulcerative colitis with positive PR3-ANCA may belong to a subtype of refractory ulcerative colitis. The particular Chinese medicine compound used in our study is by far the most effective in the management of these patients,with additional advantages of having no noticeable sideeffects and less financial burden.

    Immunomodulator therapy with thiopurine analogues azathioprine or 6-mercaptopurine is commonly prescribed for the treatment of organ transplantation, inflammatory bowel disease, autoimmune diseases and malignancies. Hepatotoxicity due to thiopurine analogues usually presents as an increase in serum transaminase levels. Toxicity is usually not severe, and a dose reduction is effective in most patients. Nodular regenerative hyperplasia (NRH) is a very rare but potentially severe complication of thiopurine-containing therapy. NRH is often asymptomatic, neither biochemical nor molecular markers are indicative for NRH. The suspicion rises when there are clinical symptoms of portal hypertension or increases in transaminases levels orthrombocytopenia. Liver biopsy is essential for definitive diagnosis. This is a case report of a 40-year-old male patient with Crohn's disease who developed increased serum levels of liver enzymes and thrombocytopenia following the administration of thiopurine. Although treatment with thiopurine was discontinued, he has further progressed and presented with acute variceal bleeding due to portal hypertension. The diagnosis of nodular regenerative hyperplasia was proven by a liver biopsy. In conclusion, NRH is a very rare but potentially severe complication of thiopurine-containing immunosuppressive therapy for IBD.

    The inclusion complexes of beta-Cyclodextrin (beta-CD) and HP-beta-Cyclodextrin (HP-beta-CD) with 6-Mercaptopurine (6-MP), Azathioprine (BAN) and 8-Azaguanine (Azan) were investigated by fluorescence. Various factors affecting the formation of inclusion complexes were discussed in detail including formation time and pH effect. The formation constants of their inclusion complexes were determined. The results indicated that their inclusion was affected significantly by laying time and pH. The formation time of beta-CD inclusion complexes is much longer than that of HP-beta-CD. The optimum pH is about pH = 7.7-12. Their maximum excitation wavelengths are all in the range of 276-285 nm and the maximum emission wavelengths are all in the range of 328-353 nm. The fluorescence signals are intensified with increasing concentration of CD. The stoichiometries of the inclusion complexes of CD with these three anticancer xanthines are all 1:1 and the formation constants are calculated.

    Full Text Available Refractory coeliac disease (RCD is a recognised complication, albeit very rare, of coeliac disease (CD. This condition is described when individuals with CD continue to experience enteropathy and subsequent or ongoing malabsorption despite strict adherence to a diet devoid of gluten for at least 12 months and when all other causes mimicking this condition are excluded. Depending on the T-cell morphology and T-cell receptor (TCR clonality at the β/γ loci, RCD can be subdivided into type 1 (normal intra-epithelial lymphocyte morphology, polyclonal TCR population and type 2 (aberrant IELs with clonal TCR. It is important to differentiate between the two types as type 1 has an 80% survival rate and is managed with strict nutritional and pharmacological management. RCD type 2 on the other hand has a 5-year mortality of 50% and can be complicated by ulcerative jejunitis or enteropathy-associated T-cell lymphoma (EATL. Management of RCD type 2 has challenged many experts, and different treatment approaches have been adopted with variable results. Some of these treatments include immunomodulation with azathioprine and steroids, methotrexate, cyclosporine, alemtuzumab (an anti CD-52 monoclonal antibody, and cladribine or fludarabine sometimes with autologous stem cell transplantation. In this article, we summarise the management approach to patients with RCD type 2.

    Full Text Available Hypertrophic pachymeningitis (HP is a rare disorder of diverse etiology. It presents with headaches, cranial neuropathies and ataxia occurring alone or in combination. Dural biopsy is essential to exclude secondary causes of pachymeningitis. There is paucity of data on biopsied cases of HP. We report three biopsy-proven cases of idiopathic hypertrophic cranial pachymeningitis. All our patients had headaches and multiple cranial neuropathies; ataxia was seen in one patient. One patient had recurrent anterior and posterior cranial neuropathies, while one each had recurrent anterior and posterior cranial neuropathies. Two patients had profound irreversible mono-ocular visual loss. All of them showed prominent pachymeningeal thickening on imaging. Infarcts were seen in one patient, which have rarely been documented. All patients showed biopsy evidence of meningeal thickening and nonspecific chronic inflammation of the dura. The disease may have a remitting and relapsing course, and usually responds to steroids. Clinical improvement was excellent in two patients and modest in one on steroid therapy. All our patients required azathioprine during the course of therapy. Early institution and long-term maintenance of steroid therapy prevents neurologic sequelae. Occurrence of abdominal inflammatory pseudotumor in a patient of HP possibly as part of multifocal fibrosclerosis has not been described earlier.

    Pharmacogenetics is the study of the association between variability in drug response and (or) drug toxicity and polymorphisms in genes. The goal of this field of science is to adapt drugs to a patient's specific genetic background and therefore make them more efficacious and safe. In this article we describe the variants in genes that influence either the efficacy or toxicity of common drugs used in the treatment of inflammatory bowel diseases (IBD), ulcerative colitis (UC),and Crohn's disease (CD) including sulfasalazine and mesalazine, azathioprine (AZA) and 6-mercaptopurine (6-MP), methotrexate (MTX), glucocorticosteroids (CSs) and infliximab. Furthermore, difficulties with pharmacogenetic studies in general and more specifically in IBD are described. Although pharmacogenetics is a promising field that already contributed to a better understanding of some of the underlying mechanisms of action of drugs used in IBD, the only discovery translated until now into daily practice is the relation between thiopurine S-methyltransferase (TPMT) gene polymorphisms and hematological toxicity of thiopurine treatment. In the future it is necessary to organize studies in well characterized patient cohorts who have been uniformly treated and systematically evaluated in order to quantitate drug response more objectively. An effort should be made to collect genomic DNA from all patients enrolled in clinical drug trials after appropriate informed consent for pharmacogenetic studies.

  1. Methotrexate: should we start using it in clinical practice?

    2013-11-01

    Therapeutic approaches in inflammatory bowel disease have changed significantly in the past decade. Early aggressive immunosuppression has become the mainstay of therapy for patients at risk for complicated disease. Azathioprine is the most widely used immunosuppressant; however, a subgroup of patients is intolerant or refractory. Since the late 1990s, methotrexate (MTX) has become more widely used as an immunomodulator in patients with chronic inflammatory diseases such as rheumatoid arthritis and psoriasis. Yet according to recent clinical data, methotrexate remained the second most commonly used immunosuppressive in inflammatory bowel diseases. Two landmark trials and subsequent studies provided evidence for the use of methotrexate in Crohn's disease, both for induction and maintenance of remission. The evidence is less solid in ulcerative colitis, for which results of further randomized controlled trials are pending (e.g. Meteor, Merit). A potential new indication of MTX could be combination therapy with biologicals. While this is state of the art therapy in rheumatoid arthritis, data in inflammatory bowel diseases are less clear. Some studies suggest that combination with immunosuppressants could prevent the development of anti-drug antibodies, while others suggested anti- TNF induced autoimmune disorders as a potential indication. In contrast, improved efficacy was not reported by one study (COMMIT). Limitations include frequent side effects, route of administration, pregnancy and concerns about long-term safety. This review summarizes current knowledge on the efficacy and side effects of methotrexate, and tries to reevaluate the drug in the current IBD armamentarium.

    2007-06-17

    The therapy of inflammatory bowel diseases is based on 5-aminosalicylates (5-ASAs) that are the forefront of treatment of mild-to-moderate active disease and maintenance; steroids are used for the treatment of moderate-to-severe active disease; immunosuppressives and sometimes antibiotics in moderate-to-severe disease; maintenance and for the treatment of selected complications. The last few years have witnessed a significant change in the treatment of Crohn's disease. Based on evidence from new clinical studies and recent meta-analyses, the role of and indications for conventional therapy have been reassessed. The 5-ASAs are nowadays less frequently used in both active disease and maintenance therapy. Instead, budesonide has been introduced in the treatment of mild-to-moderate ileal disease. Besides the modest use of 5-ASAs, steroids are prescribed for active colonic disease. Immunosuppressives, especially azathioprine, are more commonly used in moderate-to-severe disease as well as in maintenance. The preferred maintenance regimen following medically- and surgically-induced remission, in addition to relationship between medical and surgical therapies, has also changed. The recent introduction of new "biological" therapy represents a major, promising change in the therapy of resistant and penetrating disease.

    Renal involvement is frequent during natural history of systemic lupus erythematosus (SLE) and has a major prognostic value in this systemic disease. Screening for renal symptoms, such as proteinuria, micro-haematuria or renal failure must be performed at initial diagnosis and repeated during subsequent follow-ups. Any significant abnormality of these parameters may reveal active glomerulonephritis (GN) and should lead to a renal biopsy, which will significantly impact the therapeutic choices. Proliferative GN, defined as class III or IV by the actual histo-pathological classification, is the most severe form of SLE-associated nephropathy and can lead to end-stage renal disease (ESRD) in up to 60% of cases, according to ethnicity and follow-up duration. Standard induction treatment of active proliferative GN includes corticosteroids combined with an immunosuppressive drug, which can either be cyclophosphamide or mycophenolate mofetil (MMF). Even though, recent biotherapies have not yet proved their efficacy in the field of lupus nephritis, new protocols are expected, aiming higher remission rates and avoidance of high-dose corticosteroids regimens. When remission is achieved in proliferative GN, a maintenance therapy is required to decrease the risk of relapse, using either azathioprine or MMF. Immunosuppressive drugs are responsible for an increased risk of infectious or neoplastic complications but cardiovascular disease is actually one of the main causes of mortality among lupus patients, especially for patients with SLE-related kidney disease, well before reaching ESRD.

    Primary sclerosing cholangitis is an infrequent extraintestinal manifestation of ulcerative colitis. Damage to bile ducts is irreversible and medical therapies to prevent progression of the disease are usually ineffective. We describe a patient with long-standing ulcerative colitis, which was refractory to corticosteroid therapy who developed primary sclerosing cholangitis (biochemical stage II/IV) in the course of his pancolitis. Treatment with infliximab (5 mg/kg as an induction dose followed by maintenance doses every two months) was indicated because of steroid-dependent disease associated to primary sclerosing cholangitis as well as sacroiliitis and uveitis and previous episode of severe azathioprine-related hepatic toxicity. At present, after two years of follow-up, the patient is asymptomatic with normal liver tests and complete resumption of daily life activities. This case draws attention to the usefulness of anti-tumor necrosis factor-alpha therapy for the management of primary sclerosing cholangitis as extraintestinal manifestation of inflammatory bowel disease.

    Full Text Available One of the susceptibility genes in Crohn’s disease (CD is CARD15. Our study examined the relationship between peripheral CARD15 expression and phenotype and duration of CD, treatment methods and inflammatory indices. Sixty patients with CD and 30 healthy volunteers as controls were enrolled in the study. Total RNA was isolated from peripheral blood mononuclear cells (PBMCs with E.Z.N.A. Total RNA Kit (Omega Bio-tek then quantitative real-time PCR was performed on the ABI Prism 7900 HT Real-Time PCR System. CARD15 gene expression in PBMCs in CD was significantly higher than in the control group. The highest level of gene expression was found in CD patients in the fourth decade of life. The mRNA level of the CARD15 gene was higher in patients with disease duration between 12 and 60 months. A positive correlation was found between erythrocyte sedimentation rate (ESR and gene expression level. Gene expression increased with increasing level of C-reactive protein and ESR, but it was not statistically significant. CARD15 expression significantly decreased in CD patients treated with anti-TNFα agents compared to azathioprine or steroid treatment groups. Expression of the CARD15 gene in Crohn›s disease is higher than in healthy individuals. Disease duration and age of patients seem to be the most important factors influencing CARD15 expression.

  6. Reactivation of hepatitis B virus infection after cytotoxic chemotherapy or immunosuppressive therapy

    Institute of Scientific and Technical Information of China (English)

    María Luisa Manzano-Alonso; Gregorio Castellano-Tortajada

    2011-01-01

    Reactivation of hepatitis B is defined as the recurrence or an abrupt rise in hepatitis B virus (HBV) replication,often accompanied by an increase in serum transaminase levels, and both events occurring in a patient with a previous inactive hepatitis B infection. This reactivation can occur in situations in which the ratio of HBV replication and immune response is altered. It can happen during the treatment of hemato-oncological malignancies with chemotherapy and in immunosuppression of autoimmune diseases. Clinical manifestations of hepatitis B reactivation are variable and can range from asymptomatic to acute hepatitis, which are sometimes serious and result in acute liver failure with risk of death, and usually occur in the periods between cycles or at the end of chemotherapy. Immunosuppressive drugs such as corticosteroids or azathioprine can induce HBV reactivation in patients carrying hepatitis B virus surface antigen (HBsAg) or anti-HBc, but much less frequently than chemotherapy treatments. The tumor necrosis factor α inhibitors infliximab, etanercept and adalimumab may cause reactivation of hepatitis B, and the overall frequency with infliximab may be similar (50%-66%) to that caused by chemotherapy. Baseline HBV serology is recommended for all patients receiving chemotherapy and immunosuppressive drugs, and HBsAg positive patients should receive anti-HBV prophylaxis to decrease virus reactivation and death rates.

    1986-01-01

    When pretreated with total lymphoid irradiation, renal allograft recipients have an increased percentage of OKT 8 positive (cytotoxic/suppressor) T cells among their peripheral blood T lymphocytes (PBL) (56 +- 21%) and also of Leu 7 PBL (47 +- 18%). In contrast, transplant patients treated with azathioprine or cyclosporine A have percentages of OKT 8 and Leu 7 positive PBL, similar to control persons (respectively 29 +- 13, 33 +- 10, 30 +- 10 for the OKT 8+ cells and 8 +- 7, 11 +- 6 and 15 +- 9 for the Leu 7+ cells). After purification, about two thirds (70%) of the OKT 8 positive, OKT 3 positive, T lymphocytes of TLI patients were shown to co-express the Leu 7 antigen. It is concluded that after TLI, an increase of OKT 3+, OKT 8+ and Leu 7 + lymphocytes takes place, a subset previously described to be present in low numbers in control persons and whose function is still unclear. This expansion after TLI should allow functional identification of this subset and might contribute to the understanding of the immunosuppressive effects of TLI.

  8. Effect of blood transfusions on canine renal allograft survival

    In this study significantly prolonged canine renal allograft survival has been demonstrated after transfusion of 100 ml of third-party whole blood given peroperatively. Peroperative transfusions of third-party leukocyte-free blood or pure lymphocyte cell suspensions did not influence graft survival. Futhermore, no improvement in graft survival has been found after a peroperative transfuson of irradiated whole blood (2500 rad). These data suggest that delayed graft rejection after blood transfusions can only be expected after the administration of whole blood. The role of competent lymphocytes in whole blood is questionable, since a transfusion of irradiated whole blood in combination with nonirradiated lymphocytes did not lead to prolonged graft survival. Immunosuppression of the recipient directly after transfusion seems to be essential to induce the beneficial effect of blood transfusions. This has been demonstrated for a transfusion of whole blood 14 days before transplantation. A single transfusion of 100 ml of whole blood 14 days before transplantation could effectively prolong graft survival if immunosuppression with azathioprine and prednisone was started on the day of transfusion. No improvement in graft survival has been found with such a transfusion if preoperative immunosuppression has been omitted.

    A double-blind, randomized, placebo-controlled study was conducted to determine the effect of nifedipine on early renal allograft function when added to a triple therapy immunosuppression regime comprising low-dose cyclosporin (CsA), prednisolone and azathioprine. Fifty adult cadaveric renal allograft recipients were randomized to placebo (group P n = 17), nifedipine 10 mg preoperatively and 20 mg b.d. postoperatively for 48 h, followed by matching placebo for 3 months (group NS n = 16) or nifedipine 10 mg preoperatively and 20 mg b.d. postoperatively for 3 months (group NL n = 17). Donor and recipient exclusion criteria included recent calcium antagonist treatment. At 3 months after transplantation mean GFR adjusted for graft loss was significantly higher in group NL than in NS (mean +/- SD 61 +/- 28 versus 34 +/- 25 ml/min/1.73 m2; P nifedipine commenced preoperatively and continued for 3 months following transplantation has beneficial effects on early renal allograft function when incorporated as part of an immunotherapy regimen based on cyclosporin.

    A case is described of a 54-year-old 55 kg patient who presented for clipping of a middle cerebral aneurysm two years after a successful renal allograft. Immunosuppression was maintained with azathioprine 100 mg daily, cyclosporine 300 mg daily and prednisone 10 mg daily. The patient had chronic hypertension controlled with nifedipine 40 mg daily and furosemide 20 mg daily. The cyclosporine level taken on the morning of surgery was 166 micrograms.L-1. Induction of anaesthesia consisted of fentanyl 350 micrograms, thiopentone 125 mg and pancuronium 5.5 mg. Anaesthesia was maintained with nitrous oxide 70 per cent in oxygen and isoflurane 0.5-1.5 per cent. No additional doses of pancuronium were given during the four hour surgical procedure. At the end of surgery, four twitches were present with train-of-four stimulation, but evidence of residual muscle paralysis was present. Residual neuromuscular blockade was reversed with atropine 1.2 mg and neostigmine 2.5 mg. Residual paralysis was present in the Recovery Room and edrophonium 10 mg was given prior to extubation. Clinical testing demonstrated adequate reversal of neuromuscular blockade. Twenty minutes following extubation, increasing respiratory distress was noted. There was clinical evidence of muscle paralysis. The patient was re-intubated. It is proposed that cyclosporine potentiated the pancuronium blockade producing prolonged neuromuscular relaxation resulting in residual paralysis following surgery. The potential interactions of cyclosporine and muscle relaxants deserve further study.

    The comparative effects of enalapril (E) and nifedipine (N) on renal hemodynamics were assessed in twenty-two moderately hypertensive, cadaveric renal transplant patients who were maintaining stable renal function. Fourteen patients were on cyclosporin (CSA) and eight were receiving azathioprine with prednisolone (AZA). In each patient effective renal plasma flow (ERPF) was determined four times, first baseline, second with E, third as another baseline after a washout period, and fourth with N; and renal vascular resistance (RVR) was derived in each. ERPF and RVR were significantly compromised in the CSA group (202 +/- 55 ml/min and 65 +/- 18 mmHg/ml/min) compared to the AZA group (302 +/- 99 and 43 +/- 15 respectively). During E therapy, RVR further increased in the CSA group to 82 +/- 37 while it decreased in the AZA group to 31 +/- 7 (both changes were significant when compared to their respective baseline values). N, on the other hand, only significantly lowered RVR in the AZA group. Furthermore, two patients, one from each group, developed acute reversible renal failure shortly after E therapy. However, both agents were effective in lowering blood pressure to a comparable degree in both groups. In conclusion, our data showed a somewhat less favourable renal hemodynamic response to short-term enalapril therapy in hypertensive renal transplant patients maintained on CSA. However, the significance of such hemodynamic changes for long-term renal function remains uncertain.

    Hypertension present in more than 50% of successfully renal transplanted patients and its prevalence has slightly increased since the introduction of cyclosporine A. Twenty patients, 9 women and 11 men aged from 30 to 58 years, with stable cadaveric renal allograft function and moderate to severe hypertension, were included in the study. Renal artery graft stenosis causing hypertension were excluded. All patients were given triple drug immunosuppressive treatment with methylprednisolone, azathioprine and cyclosporine A (CsA) and their hypertension was treated with a nifedipine dose of 20 mg twice daily. To evaluate the effect of ACE inhibitors on renal hemodynamics and hypertension, a 4 mg/daily dose of perindopril was added to the above regimen for two months. Effective renal plasma flow (ERPF) decreased from 208 +/- 54 to 168 +/- 61 ml/min and renal vascular resistance (RVR) increased from 75 +/- 12 to 88 +/- 17 mm Hg/ml/min (P nifedipine. It is suggested that the combination of both antihypertensive agents was more effective than monotherapy with nifedipine in controlling blood pressure, but less favorable on the renal hemodynamic response in hypertensive renal transplant patients who were maintained on CsA.

    In view of the reported increase in thromboembolic episodes following cyclosporine A (CyA) therapy, the effect of this drug on platelet aggregation and thromboxane A2 release was investigated. The addition of CyA, at therapeutic concentrations to platelet rich plasma from normal subjects in vitro was found to increase aggregation in response to adrenaline, collagen and ADP. Ingestion of CyA by healthy volunteers was also associated with enhanced platelet aggregation. The CyA-mediated enhancement of aggregation was further enhanced by the addition in vitro of therapeutic concentrations of heparin. Platelets from renal allograft recipients treated with CyA also showed hyperaggregability and increased thromboxane A2 release, which were most marked at "peak" plasma CyA concentration and less so at "trough" concentrations. Platelet hyperaggregability in renal allograft patients on long-term CyA therapy tended to revert towards normal following the replacement of CyA with azathioprine. Hypertensive patients with renal allografts on nifedipine therapy had normal platelet function and thromboxane release in spite of CyA therapy. These observations suggest that CyA-mediated platelet activation may contribute to the pathogenesis of the thromboembolic phenomena associated with the use of this drug. The increased release of thromboxane A2 (a vasoconstrictor) may also play a role in mediating CyA-related nephrotoxicity.

    Full Text Available We studied the incidence and the risk factors predisposing to post transplantation urinary tract infection (UTI and the association with use of different immunosuppressive regimens. We performed a retrospective analysis of 152 recipients of renal transplantation over a period of two years. Seventy one (46.71% patients had culture positive UTI, Escherichia coli (45.1% being the commonest. Thirty four (22.39% patients had acute rejection and 14.4% of those had suffered UTI in the early post transplant period. Immunosuppression included induction with various anti-bodies and maintenance on antirejection medications. Trimethoprim-sulphamethoxazole was given as prophylaxis throughout the period. The UTI was treated according to microbiological sensitivity. 2.8% died due to urosepsis. In our retrospective analysis renal transplant recipients under the age of 45, female gender and diabetics suffered more UTI. Combination therapy with micro-emulsion form of cyclosporine A, prednisolone and azathioprine developed more UTI (P= 0.0418.

    Full Text Available Behcet′s disease is a multisystem inflammatory disorder that is most common in countries along the ancient "Silk Road". The eye is the most commonly involved vital organ in Behηet′s patients and the typical form of involvement is a relapsing remitting panuveitis and retinal vasculitis. Uveitis is the initial manifestation of the disease in 10-15% of the patients. Anterior uveitis is always nongranulomatous. Diffuse vitritis, retinal infiltrates, sheathing of predominantly retinal veins, and occlusive vasculitis are the typical signs of posterior segment inflammation. Spontaneous resolution of acute inflammatory signs is a diagnostic feature. Fundus fluorescein angiography is the gold standard in monitoring inflammatory activity. Laser flare photometry is a useful noninvasive tool since flare readings correlate with fluorescein angiographic leakage. The most common complications are cataract, maculopathy, and optic atrophy. Male patients have a more severe disease course and worse visual prognosis. Immunomodulatory therapy is indicated in all patients with posterior segment involvement. Corticosteroids combined with azathioprine and/or cyclosporine is used initially. Biologic agents, including interferon alfa and infliximab, are used in resistant cases. Visual prognosis has improved in recent years with an earlier and more aggressive use of immunomodulatory therapy and the use of biologic agents in resistant cases.

    Multiple extraintestinal diseases are present in 0.3- 4.5 % of inflammatory bowel disease patients. A 39-year-old woman was admitted with a 3 months history of cervicalgia with functional incapacity, asthenia, tibio-tarsal bilateral arthritis and bloody diarrhoea. She had ferropenic anemia, SR-120 mm, creatinine clearance-42 mL/min, proteinuria-1.2 g/24h. Colonoscopy with biopsy showed active ulcerative rectossigmoiditis. She had bilateral sacroileitis more pronounced at the right side which was suggestive of ankylosing spondylitis. HLA B27 was positive. Because of colestasis, colangio-MRI and CPRE were done and were suggestive of primary sclerosing colangitis. Renal disease was interpreted as an analgesic nephropathy versus glomerulonephritis associated with ulcerative colitis. Cardiac ecodoppler showed pericardial thickening with a thin pericardial effusion. Full improvement of gastrointestinal complaints was observed with 5-ASA topic enemas, sulfassalazine, corticosteroids and azathioprine and full remission of ankylosing spondylitis with adalimumab. This case illustrates extraintestinal wide involvement as the initial presentation of ulcerative colitis, remarking its systemic nature.

    Full Text Available Pemfigus is an autoimmune bullous skin disease, characterized by intraepidermal blisters. It is a severe and potentially life-threatening chronic disease with blisters and erosions on the mucosae and the skin. Treatment options do not differ for two most common types of pemphigus, pemphigus vulgaris and pemphigus foliaceus, except that the latter is usually less resistant to treatment and corticosteroids can often be started at lower doses. Systemic corticosteroids are still the most widely used drugs in the treatment of pemphigus and continue to be the mainstay of therapy for this disease. Adjuvant drugs are commonly used in combination with the aims of increasing efficacy and of having a steroid-sparing action, thereby allowing reduced corticosteroid side-effects. Mortality and complete remission rates have improved since the introduction of adjuvant drugs to pemphigus. Adjuvant drugs include immunoadsorbtion, corticosteroid pulse therapy, intravenous immunoglobulin (IVIG, immunosuppressive agents such as azathioprine, cyclophosphamide, mycophenolate mofetil and and anti-CD20 monoclonal antibody (rituximab. The lack of consensus in the published literature about the treatment of this disorder is responsible for different treatment strategies. Treatments need to be chosen after careful consideration of the potential benefits and side effects according to the patients’ medical condition. Here, both conventional therapies and novel treatment regimens for pemphigus are discussed. (Turkderm 2011; 45 Suppl 1: 44-53

    Full Text Available Pemphigus is an autoimmune blistering disease affecting skin and mucous membranes which threatens the life. In our country it is the most common disease in this group. In our region, among the pemphigus cases, the most common variant is pemphigus vulgaris. Pemphigus vulgaris consists of the 80% of pemphigus cases and it occurs 10 times more than pemphigus foliaceus. Treatment of pemphigus is accepted as a miracle in clinical medicine. The disease, which had an almost always fatal outcome, had been turned to the disease which long-term remissions or “cure” can be achievable. However, in the past the cause of the death was the disease itself, nowadays, with decreasing frequency, all of the mortalities is due to the treatment side effects. In treatment of pemphigus which drug to use and when to use it has varieties according to the intended effect. Corticosteroids are the main treatment; besides IVIg, plasmapheresis or pulse steroid prefers to control the disease rapidly. Mainly immunosuppressive agents (azathioprine, methotrexate, cyclophosphamide, cyclosporine, and mycophenolate besides gold, dapsone, antibiotics or rituximab are using for late-term effect and to reduce the corticosteroid requirement.

  20. Steroid sparing regimens for management of oral immune-mediated diseases

    2014-01-01

    Full Text Available Immune-mediated mucocutaneous disease may present oral symptoms as a first sign of the disease. The primary etiology could be the cellular and/or humoral immune responses directed against epithelial or connective tissue, in a chronic and recurrent pattern. Lichen planus, pemphigus vulgaris and bullous pemphigoid are the most frequent immunologically mediated mucocutaneous diseases. More often than not, patients present with complaints of blisters, oral ulcers, pain, burning sensation, and bleeding from the various oral sites. Steroids, whether topical or systemic, are the treatment of choice as they have both anti-inflammatory and immune-suppressant properties; however, challenges in the treatment of autoimmune diseases are the complexity of symptoms, the need to manage long-term medications for preserving organ function, and the long-term adverse effects of steroids. In such situations steroid sparing agents, such as, tacrolimus, dapsone, azathioprine, cyclosporine, and so on, may be helpful. Here an attempt is made to review various treatment regimens that could be used as alternatives to steroids for management of such diseases.

    Pemphigus is defined as a group of chronic self-immune vesicular diseases histologically recognized by inter-epidermic vesicles resulting from acantholysis. The aim of this study was to evaluate the precipitant and circulative IgG antibodies in patients with pemphigus vulgaris before and after treating with immunofluorescence. Sixty-two patients (34 females and 28 males) with clinically and pathologically confirmed P.V. were studied prospectively over a one year period of time during which direct and indirect immunofluorescent tests were performed before and after treatment. They had mild or moderate forms of disease. All patients received prednisolon 1-2 mg/kg/day and Azathioprine 2-3 mg/kg/day or methylpredisolon (1 g day(-1) for 4 days) and cyclophosphamide (500 mg/first day) pulse therapy due to general condition. Thirty- four females and 28 males enrolled, the mean age were 39.5 years (SD = 12.7). Before treatment, 10 and 52 cases were positive for skin depositing + or ++) and circulatory IgG (1/20 -1/60), respectively. Two to 3 month later, 37 were IgG positive with titers 1/20 to 1/160. The correlation between circulatory IgG before and after treatment was weakly positive (p = 0.05, r = 0.415). In the present study, treatment methods used for patients suffering from pemphigus vulgaris were not successful in significantly decreasing the circulative autoantibodies levels.

    Pemphigus vulgaris is a rare, potentially fatal, autoimmune blistering disease of the skin and mucous membranes. Treatment of this disease is problematic because of a lack of high-grade, evidence-based recommendations, the side-effect profiles of the therapies available, and the extensive supportive care that afflicted patients require. The authors present the unfortunate course of a patient with severe pemphigus vulgaris who was admitted to the U.S. Army Institute of Surgical Research Burn Center, to demonstrate the potential complications of therapy. Given the patient's complex course, the authors reviewed the literature and share in this article the most up-to-date treatment recommendations for patients with pemphigus vulgaris. The authors' review of the literature supports using conventional therapy consisting of high-dose corticosteroids and an adjuvant immunosuppressant for mild to moderate cases of pemphigus vulgaris. The immunosuppresants recommended are mycophenolate mofetil, azathioprine, and cyclophosphamide, in order of preference, based on their side-effect profiles and steroid-sparing effects. For severe or recalcitrant cases of pemphigus vulgaris, the authors recommend adding rituximab as early as possible. If increased risk of infection is of particular concern, the use of intravenous immunoglobulin in place of rituximab is advised.

    Full Text Available An unusual presentation of Devic’s neuromyelitis optica (NMO disease associated with bilateral internuclear ophthalmoplegia (INO is described. A 32-year-old pregnant patient was diagnosed with NMO. First symptoms were headache and sudden visual loss in her right eye (RE. Eighteen months ago, she reported other neurologic symptoms such as paresthesia. Based on her visual field, fundoscopy and Ishihara test, she was diagnosed with retrobulbar neuritis of the RE. After delivery, new neurologic symptoms resembling transverse myelitis appeared. She was treated with methylprednisolone and plasmapheresis, which improved her visual acuity; however, a sudden bilateral INO appeared, with adduction defect and nystagmus with abduction in both eyes. No improvement was obtained after treatment with azathioprine and rituximab. Paresis of the legs and the right arm persisted, but double vision and OIN gradually disappeared. At the end, the patient had a residual exophoria in the RE and nystagmus with abduction in the left eye. Prevalence of NMO is lower than one case per one million inhabitants, and it is not likely to affect the encephalic trunk; furthermore, bilateral INO in NMO is rare. Two major criteria and at least two of the three minor ones are required to confirm a NMO diagnosis, and our patient fulfilled these diagnosis criteria.

    Full Text Available Neuromyelitis optica (NMO is an autoimmune demyelinating condition of the central nervous system often associated with aquaporin-4 (AQP4 autoantibodies manifesting as severe optic neuritis and long segment myelitis with tendency to relapse. Seronegative patients and who do not meet the NMO criteria are classified as having NMO Spectrum Disorder (NMOSD, but are treated identically to clinically definite NMO. Acute relapse is treated with intravenous methylprednisolone for 5 days with or without subsequent treatment with plasma exchange (PE. This must be followed by oral steroid to prevent rebound worsening and further relapse. For relapse prevention, immunosuppressive agents that have been found to be effective are azathioprine, rituximab, mycophenolate mofetil, methotrexate, and mitoxantrone; although none of which have been validated in randomized, controlled trial. Some patients do relapse with monotherapy, and switching to more effective agent or use of combination therapy is beneficial in such situation. There is no consensus about the duration of preventive therapy, but generally 2-3 years of relapse-free period is considered the minimum, taking into account the risks of long-term toxicity of these agents.

    Infection is one of the leading causes of morbidity and mortality in systemic lupus erythematosus (SLE). Bacterial infections are most frequent, followed by viral and fungal infections. The impaired cellular and humoral immune functions seen in patients with SLE are predisposing conditions, whilst disease activity, prednisone doses over 7.5-10 mg/day, high doses of methylprednisolone or cyclophosphamide are well-recognised risk factors for infection. The first six months after rituximab treatment and the use of more than three courses are also associated with an increased susceptibility for infection. It has not been established whether belimumab, azathioprine and mycophenolate mofetil increase the risk of serious infections. Most vaccines are effective and safe in SLE patients, although vaccination should be avoided during periods of active disease. Live virus vaccines are contraindicated for immunosuppressed patients. Influenza and pneumococcal vaccines are universally recommended. Tuberculosis prophylaxis should be considered in selected cases. Therefore, it is advisable not to exceed doses of 5 mg/day of prednisone in chronic treatment. Methylprednisolone and cyclophosphamide should be used in low-dose regimens. Antimalarials have a well-known protective role against infection, in addition to other beneficial properties, thus, hydroxychloroquine is recommended for all SLE patients where no contraindication exists.

    2014-01-01

    Unmet therapeutic needs in Behçet's disease have drawn recent attention to biological agents targeting cytokines other than TNF. The anti-IL-17 antibody secukinumab and the anti-IL-2 receptor antibody daclizumab were not superior to placebo for ocular Behçet's in randomised controlled trials, comprising 118 and 17 patients, respectively. The anti-IL-1 agents anakinra and canakinumab and the anti-IL-6 agent tocilizumab were given to isolated refractory disease patients, who were either anti-TNF naïve (n=9) or experienced (n=18). No new safety signals were reported. Although a potential for bias to report positive effects and underreport negative cases may exist, Anakinra was partially effective, whereas disease remission was noted after canakinumab in some anti-TNF resistant patients. Tocilizumab appeared effective for neuro-Behçet's, but not for mucocutaneous manifestations. Finally, in a pilot study of 7 patients with relapsing posterior uveitis refractory to azathioprine and/or cyclosporine, the anti-IL-1β antibody Gevokizumab was beneficial. Collectively, it seems that IL-1 and IL-6 are promising targets in patients refractory or intolerant to other regimens including anti-TNFs. However, controlled studies are surely needed.

    Full Text Available BACKGROUND: Due to the risks related to long-term treatment with prednisone and azathioprine, most clinicians try to withdraw these drugs when patients with autoimmune hepatitis are in remission. However, there is a high probability of relapse, and most patients end up receiving maintenance treatment. AIM: To evaluate the safety and efficacy of maintenance treatment with chloroquine in the prevention of autoimmune hepatitis relapses. METHODS: Classical treatment was stopped after achievement of biochemical and histological remission of autoimmune hepatitis. Chloroquine diphosphate, 250 mg daily, was given for at least 12 months or until the occurrence of relapses defined by levels of aminotransferases at least twice the upper normal values. RESULTS: Fourteen patients were consecutively treated and compared with 18 historical controls. There was a 6.49 (1.38-30.30 greater chance of relapse in the historical controls when compared with patients treated with chloroquine (72.2% x 23.5%; 0.031. CONCLUSIONS: The group treated with chloroquine had a lower frequency of relapses. Chloroquine was safe in patients with autoimmune hepatitis and hepatic cirrhosis without decompensation, on 250 mg daily up to 2 years. These preliminary results provide a basis for upcoming controlled studies comparing chloroquine with placebo or for maintenance treatment with prednisone and/or azathioprine for the prevention of autoimmune hepatitis relapses.RACIONAL: Em razão dos riscos relacionados ao tratamento prolongado com prednisona e azatioprina, tenta-se a retirada dessas drogas em pacientes com hepatite auto-imune em remissão. Como há alta taxa de recidiva, a maioria dos pacientes recebe tratamento por tempo indefinido. OBJETIVO: Avaliar a segurança e a eficácia do tratamento de manutenção com cloroquina na prevenção de recidiva da hepatite auto-imune. MÉTODOS: O tratamento convencional foi suspenso após obtenção de remissão bioquímica e histol

    The high-resolution computed tomography (HRCT) technique is an essential component in diagnosing interstitial lung disease (ILD) as it provides important and specialized information and a much greater accuracy than chest X-rays. It contributes to a narrowing down of the differential diagnoses and is also important for planning further invasive investigations, e.g. bronchoscopy, bronchoalveolar lavage, transbronchial lung biopsy and surgical lung biopsy, if needed. An accurate diagnosis of ILD is based on a multidisciplinary discussion involving pulmonologists, radiologists and pathologists experienced in the diagnosis of ILD. The therapy approaches of five different entities of ILD are shown as examples. In hypersensitivity pneumonitis the mainstay of treatment is complete avoidance of exposure to the provoking antigen. In cryptogenic organizing pneumonia most patients recover with corticosteroid therapy with prednisolone over a period of 6 months to 1 year. In cases of sarcoidosis therapy depends on organ involvement and functional impairment but there is no durable benefit to routine treatment of patients with acute pulmonary sarcoidosis, even among those with stage II or III chest radiographs. In general, patients with severe or progressive disease will require treatment. In idiopathic pulmonary fibrosis (IPF) a confident radiological diagnosis of definitive usual interstitial pneumonia (UIP) obviates the need for surgical lung biopsy. Other etiologies of a HRCT pattern of UIP, such as domestic and occupational environmental exposure, connective tissue disease and drug toxicity must be ruled out. In IPF antifibrotic therapy with pirfenidone (approval since 2011) or the triple tyrosine kinase inhibitor nintendanib (pending approval in 2015) can reduce disease progression but therapy with acetylcysteine alone or in combination with prednisolone and azathioprine failed to meet efficacy endpoints.

    [PUVA], ciclosporin or azathioprine) were available. In the manufacturer's original submission to NICE, the base-case incremental cost-effectiveness ratios (ICERs) reported for alitretinoin were pound8614 per QALY versus ciclosporin, - pound469 per QALY versus PUVA (with alitretinoin dominant) and pound10 612 per QALY versus azathioprine (year 2007-8 values). In response to a request from the ERG, the manufacturers provided a revised model that compared alitretinoin only with placebo, for which the ICER was reported to be pound12 931. However, the omission of adverse events entirely from this revised model, in combination with a number of other factors, led the ERG to conclude that the model underestimated the costs of treatment associated with alitretinoin. Estimates of health-related quality of life (HR-QOL) were the primary source of uncertainty, with the use of values from an alternative source producing ICERs of around pound30 000 per QALY gained. The ERG concluded that, although the evidence presented indicates that alitretinoin is efficacious in the treatment of severe CHE, it gives little indication of alitretinoin's efficacy relative to likely alternative treatment options or its efficacy and safety in the longer term. Although the ICERs estimated by the manufacturer suggested that alitretinoin may be cost effective for use in the UK NHS, utilizing the alternative HR-QOL estimates resulted in a 2-fold increase in the ICER. Thus, there was considerable uncertainty as to the true ICER of alitretinoin versus the relevant treatment comparators. The Appraisal Committee recommended that alitretinoin be provided to those patients with severe CHE and a Dermatology Life Quality Index (DLQI) score of at least 15. They recommended that treatment be stopped as soon as an adequate response was observed, or if CHE remained severe at 12 weeks, or if response was inadequate at 24 weeks.

    This paper presents a summary of the evidence review group (ERG) report into the clinical effectiveness and cost-effectiveness of alitretinoin for the treatment of adults with severe chronic hand eczema refractory to topical steroid treatment in accordance with the licensed indication, based upon the evidence submission from Basilea Pharmaceuticals Ltd to the National Institute for Health and Clinical Excellence (NICE) as part of the single technology appraisal process. The clinical evidence came from a single placebo-controlled randomised controlled trial of daily treatment with alitretinoin for 12-24 weeks, with follow-up for a further 24 weeks, in patients with severe chronic hand eczema (CHE) unresponsive to topical steroids. A statistically significantly greater proportion of patients using alitretinoin achieved the primary end point of clear or almost clear hands by week 24 than did those with placebo. Dose-dependent headache was the most commonly reported adverse event in patients treated with alitretinoin. Serious adverse events were rare, but alitretinoin was associated with increases in both total cholesterol and triglycerides, which has implications for risks of future cardiovascular events. The manufacturer submitted a de novo decision analytic model to estimate, over a time horizon of 3 years, the cost-effectiveness of alitretinoin versus the other relevant comparators identified by NICE. In response to the points of clarification put to it by the ERG regarding the initial submission, the manufacturer provided additional evidence and a revised decision analytic model with a 'placebo' arm. In the manufacturer's original submission to NICE, the base-case incremental cost-effectiveness ratios (ICERs) reported for alitretinoin were 8614 pounds per quality-adjusted life-year (QALY) versus ciclosporin, -469 pounds per QALY versus psoralen + UVA (with alitretinoin dominant) and 10,612 pounds per QALY versus azathioprine. These ICERs decreased as the time

    Full Text Available Tuberculosis is one of the most frequent opportunistic infections after renal transplantation and occurred in 30 of 1264 patients transplanted between 1976 and 1996 at Hospital São Paulo - UNIFESP and Hospital Dom Silvério, Brazil. The incidence of 2.4% is five times higher than the Brazilian general population. The disease occurred between 50 days to 18 years after the transplant, and had an earlier and worse development in patients receiving azathioprine, prednisone and cyclosporine, with 35% presenting as a disseminated disease, while all patients receiving azathioprine and prednisone had exclusively pulmonary disease. Ninety percent of those patients had fever as the major initial clinical manifestation. Diagnosis was made by biopsy of the lesion (50%, positivity to M. tuberculosis in the sputum (30% and spinal cerebral fluid analysis (7%. Duration of treatment ranged from 6 to 13 months and hepatotoxicity occurred in 3 patients. The patients who died had a significant greater number of rejection episodes and received higher doses of corticosteroid. In conclusion, the administration of cyclosporine changed the clinical and histopathological pattern of tuberculosis occurring after renal transplantation.A tuberculose é uma das mais frequentes infecções oportunistas encontradas após o transplante renal.

    Full Text Available Abstract Background Extraintestinal manifestations of Crohn's disease may involve the skin, the eyes, the genital mucosa, and the joints. Dermatoses associated with Crohn's disease include neutrophilic dermatoses, erythema nodosum, granulomatous dermatitis, blistering dermatoses, and non-specific skin manifestations. Cutaneous Crohn's disease is characterized by skin non-caseating epithelioid granulomatas with giant cells, remote from the gastrointestinal tract. We report herein two new cases. Observations On both patients, differential diagnosis of neutrophilic dermatoses and infectious disease were evoked, and antimicrobial agents were introduced in one of them. Given the atypical presentation, the final diagnosis of cutaneous Crohn's disease could only be made with histological examination. In patient 1, the plaques decreased in size and infiltration by more than 75% after 3 weeks of treatment with bethametasone dipropionate 0.05% cream. In patient 2, the plaques decreased by more than 50% after 6 weeks of treatment with prednisolone (45 mg/day and azathioprine (100 mg/day. Discussion Cutaneous Crohn's disease may present as dusky, erythematous, infiltrated, and ulcerated plaques and nodules. Female-to-male sex ratio is about 2, and the mean age at onset is 35. Recurrently, the hypothesis of a skin mycobacterial or fungal infection greatly delays proper treatment. Rarity of cutaneous Crohn's disease hampers therapeutic assessment in controlled trials. Thus, available literature is limited to case reports and sparse small series, with contradictory results. These reports are subject to publication bias, and no definite evidence-based recommendations can be made on the most adequate therapeutic strategy.

  14. Metabolite monitoring to guide thiopurine therapy in systemic autoimmune diseases.

    6-Thioguanine nucleotide (6-TGN) is the active metabolite of thiopurine drugs azathioprine and 6-mercaptopurine. 6-Methylmercaptopurine (6-MMP) is an inactive and potentially hepatotoxic metabolite. A subgroup of patients (shunters) preferentially produce 6-MMP instead of 6-TGN, therefore displaying thiopurine resistance and risk for hepatotoxicity. Outside inflammatory bowel disease literature, few data exist regarding individualized thiopurine therapy based on metabolite monitoring. This study sought to describe metabolite monitoring in patients receiving weight-based thiopurine for systemic autoimmune diseases. Patients were enrolled using a laboratory database, and data were retrospectively collected. The correlation between the highest thiopurine dose (mg/kg) and the 6-TGN concentration (pmol/8 × 10(8) erythrocytes) was estimated with Pearson's correlation coefficient. Seventy-one patients with various systemic autoimmune conditions were enrolled. The correlation between the thiopurine dose and the 6-TGN level was weak for the overall patient sample (r = 0.201, p = 0.092) and for the subgroup of non-shunters (r = 0.278, p = 0.053). Subjects with 6-MMP levels >5700 pmol/8 × 10(8) erythrocytes had more hepatic cytolysis compared to subjects with 6-MMP 5700. Eleven non-shunters had hepatotoxicity, one of which had 6-MMP >5700. Thiopurine metabolite monitoring shows wide variability in 6-TGN levels among patients treated with weight-based thiopurine for systemic autoimmune diseases. Thirty-one percent of the patients in our series fulfilled the shunter definition. Thiopurine metabolite monitoring and dose adjustment to improve maintenance of remission and avoid hepatotoxicity should be studied prospectively.

    Neuropsychiatric systemic lupus erythematosus (NPSLE) is a generic definition referring to a series of neurological and psychiatric symptoms directly related to systemic lupus erythematosus (SLE). NPSLE includes heterogeneous and rare neuropsychiatric (NP) manifestations involving both the central and peripheral nervous system. Due to the lack of a gold standard, the attribution of NP symptoms to SLE represents a clinical challenge that obligates the strict exclusion of any other potential cause. In the acute setting, management of these patients does not differ from other non-SLE subjects presenting with the same NP manifestation. Afterwards, an individualized therapeutic strategy, depending on the presenting manifestation and severity of symptoms, must be started. Clinical trials in NPSLE are scarce and most of the data are extracted from case series and case reports. High-dose glucocorticoids and intravenous cyclophosphamide remain the cornerstone for patients with severe symptoms that are thought to reflect inflammation or an underlying autoimmune process. Rituximab, intravenous immunoglobulins, or plasmapheresis may be used if response is not achieved. When patients present with mild to moderate NP manifestations, or when maintenance therapy is warranted, azathioprine and mycophenolate may be considered. When symptoms are thought to reflect a thrombotic underlying process, anticoagulation and antiplatelet agents are the mainstay of therapy, especially if antiphospholipid antibodies or antiphospholipid syndrome are present. Recent trials on SLE using new biologicals, based on newly understood SLE mechanisms, have shown promising results. Based on what we currently know about its pathogenesis, it is tempting to speculate how these new therapies may affect the management of NPSLE patients. This article provides a comprehensive and critical review of the literature on the epidemiology, pathophysiology, diagnosis, and management of NPSLE. We describe the most

    Systemic lupus erythematosus (SLE) is a rare, severe, multisystem autoimmune disorder. Childhood-onset SLE (cSLE) follows a more aggressive course with greater associated morbidity and mortality than adult-onset SLE. Its aetiology is yet to be fully elucidated. It is recognised to be the archetypal systemic autoimmune disease, arising from a complex interaction between the innate and adaptive immune systems. Its complexity is reflected by the fact that there has been only one new drug licensed for use in SLE in the last 50 years. However, biologic agents that specifically target aspects of the immune system are emerging. Immunosuppression remains the cornerstone of medical management, with glucocorticoids still playing a leading role. Treatment choices are led by disease severity. Immunosuppressants, including azathioprine and methotrexate, are used in mild to moderate manifestations. Mycophenolate mofetil is widely used for lupus nephritis. Cyclophosphamide remains the first-line treatment for patients with severe organ disease. No biologic therapies have yet been approved for cSLE, although they are being used increasingly as part of routine care of patients with severe lupus nephritis or with neurological and/or haematological involvement. Drugs influencing B cell survival, including belimumab and rituximab, are currently undergoing clinical trials in cSLE. Hydroxychloroquine is indicated for disease manifestations of all severities and can be used as monotherapy in mild disease. However, the management of cSLE is hampered by the lack of a robust evidence base. To date, it has been principally guided by best-practice guidelines, retrospective case series and adapted adult protocols. In this pharmacological review, we provide an overview of current practice for the management of cSLE, together with recent advances in new therapies, including biologic agents.

    A 74-year-old gentleman was admitted to the regional neurosciences center with encephalopathy, myokymia, and dysautonomia. Chest imaging had previously identified an incidental mass in the anterior mediastinum, consistent with a primary thymic tumor. Antivoltage-gated potassium channel (anti-VGKC) antibodies were positive (titer 1273 pmol/L) and he was hypokalemic. Electromyogram and nerve conduction studies were in keeping with peripheral nerve hyperexcitability syndrome, and an electroencephalogram was consistent with encephalopathy. A diagnosis of Morvan syndrome was made, for which he was initially treated with high-dose steroids, followed by a 5-day course of intravenous immunoglobulin (IVIG) therapy. He also underwent thymectomy, followed by a postexcision flare of his symptoms requiring intensive care management. Further steroids, plasmapheresis, and IVIG achieved stabilization of his clinical condition, enabling transfer for inpatient neurorehabilitation. He was commenced on azathioprine and a prolonged oral steroid taper. A subsequent presumed incipient relapse responded well to further IVIG treatment. This case report documents a thymoma-associated presentation of anti-VGKC-positive Morvan syndrome supplemented by patient and carer narrative and video, both of which provide valuable further insights into this rare disorder. There are a limited number of publications surrounding this rare condition available in the English literature. This, combined with the heterogenous presentation, association with underlying malignancy, response to treatment, and prognosis, provides a diagnostic challenge. However, the association with anti-VGKC antibody-associated complexes and 2 recent case series have provided some scope for both accurate diagnosis and management. PMID:26740856

    Full Text Available A 68-year-old male patient was referred to our institution in May 2011 for a suspected tumor in the pancreatic head with consecutive jaundice. Using magnetic resonance imaging, further differentiation between chronic inflammation and a malignant process was not possible with certainty. Apart from cholestasis, laboratory studies showed increased values for CA 19-9 to 532 U/ml (normal <37 U/ml and hypergammaglobulinemia (immunoglobulin G, IgG of 19.3% (normal 8.0–15.8% with an elevation of the IgG4 subtype to 2,350 mg/l (normal 52–1,250 mg/l. Endoscopic retrograde cholangiopancreatography revealed a prominent stenosis of the distal ductus hepaticus communis caused by pancreatic head swelling and also a bihilar stenosis of the main hepatic bile ducts. Cytology demonstrated inflammatory cells without evidence of malignancy. Under suspicion of autoimmune pancreatitis with IgG4-associated cholangitis, immunosuppressive therapy with steroids and azathioprine was started. Follow-up endoscopic retrograde cholangiopancreatography after 3 months displayed regressive development of the diverse stenoses. Jaundice had disappeared and blood values had returned to normal ranges. Moreover, no tumor of the pancreatic head was present in the magnetic resonance control images. Due to clinical and radiological similarities but a consecutive completely different prognosis and therapy, it is of fundamental importance to differentiate between pancreatic cancer and autoimmune pancreatitis. Especially, determination of serum IgG4 levels and associated bile duct lesions induced by inflammation should clarify the diagnosis of autoimmune pancreatitis and legitimate immunosuppressive therapy.

    We reviewed the records of the renal transplant patients followed at our hospital to determine short-term outcome and complications. Sixty-five renal transplant patients, follow-up for two years were included in this study. Of these patients 40 (61.5%) were males, 33 (50.7%) were Saudis with mean age of 37.2 +/- 11.7 years. Donors were living related (LRD) in 23 (35%), living non-related (LNRD) in 27 (42%) and cadaveric (CAD) in 15 (23%). Thirty-two transplants were carried out at Medinah, 21 in India and the rest in other centers inside Saudi Arabia. Immunosuppression was based on a triple therapy (Cyclosporin, Azathioprine, and Prednisone). At two years, 52 (80%) patients were alive, with functioning graft in 31 (58%). Causes of death among 13 patients (11 LNRD & 2 CAD) were infections in 7 (54%), immediate post transplant in three (22.7%), acute myocardial infarction in two (15.7%), CVA in one (7.6%). Complications encountered were acute rejection (23 episodes) in 18 923.6%) patients, infections in 19 (25%), chronic rejection in 16 (21.5%), surgical in 13 917.1%), diabetes mellitus in 5 (6.5%) primary non-function in three (3.8%) and Kaposi Sarcoma in two (2.4%). Twenty-six (81.25%) out of 32 transplants performed in Madinah were functioning, four (12.5%) patients returned to dialysis and two (6.25%) patients died. Among the 21 transplants done in India 11 (52%) patients died, six (28.6%) returned to dialysis, and four (19.4%) had function deteriorated in all patients. We conclude that despite limitations, results of renal transplantation carried out at Madinah are encouraging on short-term basis. Live related transplant has a very good outcome, while commercial transplantation carries poor prognosis.

    Full Text Available Peliosis hepatis is a rare liver disease characterized by blood-filled cavities scattered irregularly throughout the liver. Risk factors for peliosis include chronic illness such as AIDS, tuberculosis, cancer also use of some drugs such as anabolic steroids and azathioprine. The aim of the present study was to evaluate the curative properties of crocus sativus petals on induced peliosis hepatis in rats. Thirty two male Wistar rats (weight: 180-220 g were randomly divided into four equal groups: group 1 (healthy group received only IP normal saline, group2 received IP 80mg/kg.bw gentamicin, group3 IP 80mg/kg.bw gentamicin+ 40mg/kg crocus sativus petal extract, and group 4 was given IP 80mg/kg.bw gentamicin+ 40mg/kg crocus sativus petal extract. At the end of the experiment, the rats were anesthetized and their blood samples were collected through cardiac puncture for AST and ALT measurement.Then, the livers of the subjects were excised and fixed in formalin. It was found that AST significantly increased in gentamicin group (P<0.05 compared to the healthy group and groups treated by means of crocus sativus petal extract .Moreover, there was no significant differences between the groups administered the extract and those given gentamicin. Histologically,heterogeneous multiple blood-filled cavities were observed in gentamicin group (2 and the treatment groups (3 and 4. The results of the present study show that doses of hydroalcoholic extract of crocus sativus do not effect on peliosis hepatic and telangiectasis due to gentamicin sulfate in rats

    Enzyme replacement therapy (ERT) can produce anti-drug antibody (ADA) responses that reduce efficacy or lead to hypersensitivity reactions. Six patients with severe mucopolysaccharidosis type I (MPS I/Hurler syndrome) who did not receive hematopoietic stem cell transplantation underwent an immunosuppression regimen prior to initiating ERT with laronidase. The primary endpoint for immune tolerance induction was the number of patients with an ADA titer ≤ 3200 after 24 weeks of laronidase at the labeled dose. Cyclosporine levels were measured weekly and doses adjusted to maintain trough levels above 400 mg/mL. A 6-week (Cohort 1) or 12-week (Cohort 2) immune tolerance induction period with cyclosporine (initial dose: 15 or 20 mg/kg/day), azathioprine (initial dose: 2.5 or 5 mg/kg/day) and low-dose laronidase infusions (0.058-0.29 mg/kg/week) was followed by an immune-challenge period with laronidase infusions at the labeled dose (0.58 mg/kg/week) for 24 weeks. Anti-laronidase IgG titers were determined following treatment. There were 147 treatment-emergent adverse events reported, most of which were mild and not related to the study treatment. While there was no evidence of immune tolerance in 3 of 3 patients in Cohort 1, there were some indications of immune tolerance induction in 2 of 3 patients in Cohort 2. Patients with lower ADA titers showed greater reductions in urinary glycosaminoglycan excretion. Routine monitoring of plasma cyclosporine parent-compound levels by high pressure liquid chromatography proved difficult for clinical practice. The evolving clinical management of MPS I and a better understanding of the clinical impact of laronidase-related immunogenicity require reassessment of immune modulation strategies in patients with MPS I receiving laronidase treatment.

    Systemic lupus erythematosus (SLE) is an autoimmune disease and can cause multi-organ damage. Peritoneal involvement, also called lupus peritonitis, is a rare but sometimes fatal manifestation. Deposition of immune complexes consisting of immunoglobulin G and complement is considered to be involved in the pathogenesis of lupus peritonitis; however, it remains unknown whether inflammatory cytokines contribute to the pathology of this manifestation. Here we present two patients with treatment-resistant lupus peritonitis: a 37-year-old woman with a 26-year history of SLE who had been treated with prednisolone and cyclophosphamide followed by azathioprine and a 65-year-old woman with a 33-year history of SLE who had been treated with prednisolone alone. Both patients were admitted to our department because of abdominal distention. Computed tomography scans showed massive ascites. Ascitic fluid examinations of both patients showed leukocytosis with no evidence of malignancy or infection. After eliminating other causes for ascites, they were diagnosed with lupus peritonitis. Despite the intensified immunosuppressive therapy, they died of uncontrolled peritonitis several months after admission. Examinations of the ascites at admission also revealed a large content of interleukin (IL)-6, compared with other inflammatory cytokines, IL-1β and tumor necrosis factor-α. In fact, the ascitic IL-6 levels of these two patients were 12,389 pg/mL and 5,486 pg/mL, much higher than their serum IL-6 levels of 36 pg/mL and 140 pg/mL, respectively. We therefore suggest that IL-6 may contribute to the pathogenesis of lupus peritonitis and that the inhibition of IL-6 signaling may provide a novel therapeutic strategy for lupus peritonitis.

    Full Text Available Late recurrent primary biliary cirrhosis (PBC following orthotopic liver transplant remains a controversial topic. The first documented case of recurrence occurring in 16 patients transplanted for PBC and followed at the authors' institution for longer than one year is presented. A 54-year-old man transplanted for PBC developed a cholestatic pattern of enzyme elevation on post-transplant day (PTD 1305. Repeat antimitochondrial antibody was strongly positive (1:300 to 1:400. A liver biopsy revealed severe bile duct damage, lymphocytic cholangitis, focal periductal noncaseating granuloma and minimal endotheliitis. Recurrent PBC was diagnosed. At the time of orthotopic liver transplant this patient received induction immunosuppression with OKT3 crossed over to cyclosporine (CsA, azathioprine (AZA and prednisone. AZA was discontinued early and maintenance CsA tapered to a target trough level of 150 to 200 ng/mL by PTD 365. Prednisone was withdrawn by PTD 664. CsA levels during PTDs 1225 to 1305 (before elevation of hepatobiliary enzymes were below target at 114 to 166 ng/mL. Of the 16 patients, all but three were maintained on CsA, AZA and prednisone. One was on CsA (trough levels on target and AZA; the other two, including the patient with recurrent PBC, were on CsA only. The trough CsA level of the patient without recurrent PBC has been within the target range. The authors speculate that the underlying defect in immunoregulation in PBC persists post-transplant and that in the patient without recurrent PBC this defect was unmasked by lowered maintenance immunosuppression - allowing recurrence of PBC in a previously stable liver allograft.

    2012-01-01

    Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by B cell hyperactivity and defective T-cell function, and several cytokine aberrations, with high titer production of autoantibodies and clinical involvement in multiple organ systems. It can present with a wide variety of symptoms, most commonly involving the skin, joints, kidneys, and blood vessels. Patients with mild SLE can be treated with non-steroidal antiinflammatory drugs and antimalarials. Corticosteroids, azathioprine and cyclophosphamide, remain important for long term management of most patients with active disease. In recent years, significant progress in molecular and cellular biology of SLE has resulted in a better characterization and understanding of the biology and prognosis of this disease. These achievements have provided new opportunities for the development of innovative, more effective, therapies. Novel agents potentially useful in the treatment of patients with SLE include tolerogens, monoclonal antibodies and other agents. Tolerogens are synthetic molecules that can bind and cross-link autoantibodies on reactive B-cell surface, promoting B-cell depletion or inactivity. An anti-DNA antibody based peptide, pCons, might have also therapeutic efficacy in SLE patients who are positive for anti-DNA antibodies. In addition, prasterone, a proprietary synthetic dehydroepiandrosterone product is under investigation for the treatment of SLE. Blockade of TLR9 with specific G-rich DNAoligonucleotids also suppresses lupus activity. Several newer mAbs have been developed and are being evaluated in phase I/II clinical trials. These include newer anti-CD20 mAbs, anti-cytokine therapies, anti-BLys mAbs and anti-C5 mAbs. Most of the new agents which could be potentially useful in the treatment of patients with SLE need further laboratory investigations and clinical trials. In this review, promising new agents, potentially useful in SLE, are presented.

    Systemic lupus erythematosus (SLE) is an autoimmune disease that is associated with the production of autoantibodies, and with considerable morbidity and mortality. There has been much interest in developing more specific therapies for this disease, which is currently managed with immunosuppressive drugs, predominantly corticosteroids, azathioprine, methotrexate and cyclophosphamide, in combination with hydroxychloroquine. Mycophenolate mofetil has been demonstrated to be as efficacious as cyclophosphamide in patients with lupus nephritis, and is being used increasingly in the clinic despite not being licensed for this indication. Novel methods of reducing autoantibody formation in SLE include the use of mAbs that modulate and/or deplete B-cells (anti-CD22 and anti-CD20 antibodies, respectively), or that interfere with the stimulatory effects of the soluble factor B-lymphocyte stimulator (anti-BLys antibodies). Alternative approaches include the use of atacicept (Merck Serono), a transmembrane activator and calcium modulator ligand interactor (TACI)-Ig fusion protein, which inhibits B-cell stimulation by binding to BLys and a profileration-inducing ligand (APRIL), or toleragens such as abetimus. Blocking costimulatory molecule interactions, such as the CD40-CD40 ligand interaction with mAbs and the CD28-B7 interaction with a soluble cytotoxic T-lymphocyte antigen 4 (CTLA-4)-IgG1 construct (abatacept), has also been attempted as a therapeutic strategy for SLE. The most promising strategy for a new drug for SLE is belimumab (Human Genome Sciences/GlaxoSmithKline), an anti-BLys antibody, as two phase III clinical trials with this drug recently met their primary endpoints. In this review, these novel approaches to the treatment of SLE, including the potential of targeting cytokine pathways involved in autoimmunity, are discussed.

    The most frequent localization of ulcerative colitis(UC) is the distal colon.In treating patients with active distal UC,efficacy and targeting of the drug to the distal colon are key priorities.Oral and rectal 5-aminosalicylic acid(5-ASA) preparations represent the first line therapy of mild-to-moderate distal UC for both induction and maintenance treatment.It has been reported that many UC patients are not adherent to therapy and that noncompliant patients had a 5-fold risk of experiencing a relapse.These findings led to the introduction of oncedaily oral regimens of 5-ASA as better therapeutic options in clinical practice due to improved adherence.New formulations of mesalazine,including the multimatrix delivery system,and mesalazine granules,which allow once-daily administration,have been developed.They have been demonstrated to be efficacious in inducing and maintaining remission in mild-to-moderate distal UC in large clinical trials.However,existing data for distal UC are rather insufficient to make a comparison between new and classical 5-ASA formulations.It seems that the new formulations are at least as effective as classical oral 5-ASA formulations.Other treatment options,in the case that 5-ASA therapy is not effective,include systemic corticosteroids,thiopurines(azathioprine or 6-mercaptopurine),cyclosporine,infliximab and surgery.The combination of a prompt diagnostic work-up,a correct therapeutic approach and an appropriate follow-up schedule is important in the management of patients with distal UC.This approach can shorten the duration of symptoms,induce a prolonged remission,improve patient’s quality of life,and optimize the use of health resources.

    Canine histiocytic ulcerative colitis (HUC) is characterized by colonic inflammation with predominantly periodic acid-Schiff (PAS)-positive macrophages. The inflammation results in colonic thickening, ulcerations, and distortion of normal glandular architecture. Resultant clinical signs consist of chronic large bowel diarrhea, tenesmus, and marked weight loss, and the disease frequently results in euthanasia. Conventional therapy consists of some combination of prednisone, azathioprine, sulfasalazine, and metronidazole. Nine dogs (8 Boxers and 1 English Bulldog) with histologic confirmation of HUC were treated with antibiotic therapy (either with enrofloxacin alone or in combination with metronidazole and amoxicillin). Clinical signs, physical examination findings, laboratory abnormalities, and the histologic severity of the disease were evaluated. Four of the 9 dogs had been treated previously with conventional therapy and had failed to respond favorably; then, these dogs were placed on antibiotic therapy (enrofloxacin, n = 1; enrofloxacin, metronidazole, and amoxicillin, n = 3) and had resolution of clinical signs within 3-12 days. Five dogs were treated solely with antibiotic therapy (enrofloxacin, n = 1; enrofloxacin and metronidazole, n = 1; enrofloxacin, metronidazole, and amoxicillin, n = 3), and clinical signs resolved in 2-7 days. Repeated biopsy specimens were obtained from 5 dogs after treatment, and all showed marked histologic improvement. The increase in body weight after treatment was statistically significant (P = .01). Three dogs currently are not on any treatment and have had resolution of clinical signs for up to 14 months. These observations suggest that an infectious agent responsive to antibiotics plays an integral role in the clinical manifestation of canine HUC, and they support the use of antibiotics in its treatment.

    Post-transplant diabetes mellitus is a frequent complication of solid organ transplantation that generally requires treatment with lifestyle interventions and antidiabetic medication. A number of demonstrated and potential pharmacokinetic drug-drug interactions (DDIs) exist between commonly used immunosuppressants and antidiabetic drugs, which are comprehensively summarized in this review. Cyclosporine (CsA) itself inhibits the cytochrome P450 (CYP) 3A4 enzyme and a variety of drug transporters. As a result, it increases exposure to repaglinide and sitagliptin, will likely increase the exposure to nateglinide, glyburide, saxagliptin, vildagliptin and alogliptin, and could theoretically increase the exposure to gliquidone and several sodium-glucose transporter (SGLT)-2 inhibitors. Currently available data, although limited, suggest that these increases are modest and, particularly with regard to gliptins and SGLT-2 inhibitors, unlikely to result in hypoglycemia. The interaction with repaglinide is more pronounced but does not preclude concomitant use if repaglinide dose is gradually titrated. Mycophenolate mofetil and azathioprine do not engage in DDIs with any antidiabetic drug. Although calcineurin inhibitors (CNIs) and mammalian target of rapamycin inhibitors (mTORi) are intrinsically prone to DDIs, their disposition is not influenced by metformin, pioglitazone, sulfonylureas (except possibly glyburide) or insulin. An effect of gliptins on the disposition of CNIs and mTORi is unlikely, but has not been definitively ruled out. Based on their disposition profiles, glyburide and canagliflozin could affect CNI and mTORi disposition although this requires further study. Finally, delayed gastric emptying as a result of glucagon-like peptide-1 agonists seems to have a limited, but not necessarily negligible effect on CNI disposition.

    Data on patients with crescentic glomerulonephritis (greater than 50% glomeruli with crescents), referred to the Hospital for Sick Children during the past 13 years, were reviewed. Thirty patients (13 male, 17 female) aged 3.7-15.7 years (mean 9.5) were evaluated. Initial clinical features included: oedema (24/30), hypertension (19/30), gross haematuria (15/30), oliguria (15/30) and a decreased glomerular filtration rate (GFR less than 30 ml/min per 1.73 m2) (22/30). Henoch-Schönlein purpura was present in 9 patients, microscopic polyarteritis in 3, polyarteritis nodosa in 1, Wegener's granulomatosis in 1, systemic lupus erythematosus in 1, post-streptococcal glomerulonephritis in 2, mesangiocapillary glomerulonephritis in 7, anti-glomerular basement membrane glomerulonephritis in 2, and 4 were idiopathic. In 10 patients 50%-79% of glomeruli were affected by crescentic changes (group 1) and in the remaining 20, 80% or more (group 2). The crescents were cellular, fibrocellular or fibrous, and the degree of sclerosis was assessed. Patients in both groups were treated with plasma exchange, corticosteroids, anticoagulants, cyclophosphamide and azathioprine in different combinations. On follow-up, 3 patients were dead, 1 was lost to follow-up, 12 were on dialysis/transplant programmes, 4 had a GFR of less than 30 and 10 a GFR of more than 30 ml/min per 1.73 m2. In our experience, 50% progressed to end-stage renal failure. The interval between disease onset and start of treatment was a prognostic factor for outcome. Fibrous crescents were associated with a worse outcome than fibrocellular crescents (P less than 0.05). Outcome was not, however, related to the percentage of glomeruli affected (P greater than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

    2009-05-29

    Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is an immune-mediated disorder with variable symptoms and severity that can be difficult to diagnose. Intravenous immunoglobulin, plasma exchange and corticosteroids have all been proven to be beneficial in randomized controlled trials, although the proof for corticosteroids is less clear. Although these treatments are likely to be similar in efficacy, they differ in terms of their cost, availability and adverse effects. These characteristics should be taken into account when deciding which treatment to offer a patient. If there is no response to the first treatment option, one of the other treatments should be tried. Patients with a pure motor CIDP may deteriorate after corticosteroid treatment. Some patients do not respond or become refractory or intolerant to these conventional treatments. Those who become unresponsive to therapy should be checked again for the appearance of a monoclonal protein or other signs of malignancy. Over the years, small non-randomized studies have reported possible beneficial effects of various immunosuppressive agents. A Cochrane review concluded that currently there is insufficient evidence to decide whether these immunosuppressive drugs are beneficial in CIDP. When giving immunosuppressive drugs, one should be aware that some might even cause demyelinating disease. It is difficult to prove beneficial effects of these newer treatments since they have only been used in small groups of patients, who are refractory to other treatments, and often in combination with other treatments. CIDP patients can deteriorate during or after infections or improve spontaneously, making it more difficult to judge treatment efficacy. Various treatments for CIDP are described such as azathioprine, ciclosporin, cyclophosphamide, interferons, methotrexate, mycophenolate mofetil, rituximab and etanercept. An overview of these newer treatments, their mode of action, adverse effects and

    Summary Background Large leg ulcers (LLU) may complicate autoimmune diseases. They pose a therapeutic challenge and are often resistant to treatment. To report three cases of autoimmune diseases complicated with LLU. Case Report Case 1. A 55-year old woman presented with long-standing painful LLU due to mixed connective tissue disease (MCTD). Biopsy from the ulcer edge showed small vessel vasculitis. IV methylprednisolone (MethP) 1 G/day, prednisolone (PR) 1mg/kg, monthly IV cyclophosphamide (CYC), cyclosporine (CyA) 100mg/day, IVIG 125G, ciprofloxacin+IV Iloprost+enoxaparin+aspirin (AAVAA), hyperbaric oxygen therapy (HO), maggot debridement and autologous skin transplantation were performed and the LLU healed. Case 2. A 45-year old women with MCTD developed multiple LLU’s with non-specific inflammation by biopsy. MethP, PR, hydroxychloroquine (HCQ), azathioprine (AZA), CYC, IVIG, AAVAA failed. Treatment for underlying the LLU tibial osteomyelitis and addition of CyA was followed by the LLU healing. Case 3. A 20-year-old man with history of polyarteritis nodosa (PAN) developed painful LLU’s due to small vessel vasculitis (biopsy). MethP, PR 1 mg/kg, CYC, CyA 100 mg/d, AAVAA failed. MRSA sepsis and relapse of systemic PAN developed. IV vancomycin, followed by ciprofloxacin, monthly IVIG (150 g/for 5 days) and infliximab (5 mg/kg) were instituted and the LLU’s healed. Conclusions LLU are extremely resistant to therapy. Combined use of multiple medications and services are needed for healing of LLU due to autoimmune diseases. PMID:21169912

    Background Cancer is currently among the three leading causes of death after solid organ transplantation and its incidence is increasing. Non-melanoma skin cancer - squamous cell carcinoma and basal cell carcinoma - is the most common malignancy found in kidney transplant recipients (KTRs). The incidence of non-melanoma skin cancer in KTRs has not been extensively studied in Portugal. Objectives To determine the incidence of non-melanoma skin cancer in KTRs from the largest Portuguese kidney transplant unit; and to study risk factors for non-melanoma skin cancer. Methods Retrospective analysis of clinical records of KTRs referred for the first time for a dermatology consultation between 2004 and 2013. A case-control study was performed on KTRs with and without non-melanoma skin cancer. Results We included 288 KTRs with a median age at transplantation of 47 years, a male gender predominance (66%) and a median transplant duration of 3.67 years. One fourth (n=71) of KTRs developed 131 non-melanoma skin cancers, including 69 (53%) squamous cell carcinomas and 62 (47%) basal cell carcinomas (ratio squamous cell carcinoma: basal cell carcinoma 1.11), with a mean of 1.85 neoplasms per patient. Forty percent of invasive squamous cell carcinomas involved at least two clinical or histological high-risk features. The following factors were associated with a higher risk of non-melanoma skin cancer: an older age at transplantation and at the first consultation, a longer transplant duration and the presence of actinic keratosis. KTRs treated with azathioprine were 2.85 times more likely to develop non-melanoma skin cancer (p=0.01). Conclusion Non-melanoma skin cancer was a common reason for dermatology consultation in Portuguese KTRs. It is imperative for KTRs to have access to specialized dermatology consultation for early referral and treatment of skin malignancies. PMID:27579740

    Autoimmune hepatitis (AIH),initially known as chronic active or active chronic hepatitis (and by various other names),first came under clinical notice in the late 1940s.However,quite likely,chronic active hepatitis (CAH) had been observed prior to this and was attributed to a persistently destructive virus infection of the liver.An earlier (and controversial) designation in 1956 as lupoid hepatitis was derived from associated L.E.cell test positivity and emphasized accompanying multisystem features and immunological aberrations.Young women featured prominently in early descriptions of CAH.AIH was first applied in 1965 as a descriptive term.Disease-characteristic autoantibodies were defined from the early 1960s,notably antinuclear antibody (ANA),smooth muscle antibody (SMA) and liver-kidney microsomal (LKM) antibody.These are still widely used diagnostically but their relationship to pathogenesis is still not evident.A liver and disease specific autoantigen has long been searched for but unsuccessfully.Prolonged immunosuppressive therapy with predisolone and azathioprine in the 1960s proved beneficial and remains standard therapy today.AIH like many other autoimmune diseases is associated with particular HLA alleles especially with the "ancestral" B8,DR3 haplotype,and also with DR4.Looking forwards,AIH is one of the several enigmatic autoimmune diseases that,despite being (relatively) organ specific,are marked by autoimmune reactivities with non-organ-specific autoantigens.New paradigms are needed to explain the occurrence,expressions and pathogenesis of such diseases.

    There are conflicts on whether influenza vaccinated systemic lupus erythematosus (SLE) patients are associated with a decreased immunogenicity and safety, compared with healthy controls. We conducted meta-analyses to compare SLE patients with healthy controls for flu-vaccine immunogenicity, as well as for adverse events.PubMed, MEDLINE, and Cochrane Library were searched by October 15, 2015. Studies were included when they met the inclusion criteria. Two reviewers independently extracted data on study characteristics, methodological quality, and outcomes. The primary outcome was seroprotection (SP) rate after immunization.A total of 15 studies were included. There were significant differences in SP rates between the SLE patients and healthy controls, respectively, for H1N1 (RR 0.79, 95% CI 0.73-0.87) and B strain (RR 0.75, 95% CI 0.65-0.87), but not for H3N2 (RR 0.84, 95% CI 0.68-1.03). Subgroup analyses demonstrated SLE patients with immunosuppressants, corticosteroids, azathioprine and prednisone had significantly lower SP rates, compared with healthy controls. SLE patients with nonadjuvanted H1N1 vaccine had significantly lower SP rate, compared with healthy controls. SLE patients were not associated with increased adverse events (RR 1.88, 95% CI 0.94-3.77).SLE generates immunogenicity differently, compared with healthy controls in pandemic H1N1 and B strains, but same in seasonal H3N2 strain. Nonadjuvant and special kind of immunosuppressive biologics can play an important role in SLE immunogenicity to flu vaccine. There is no significant difference in adverse event rates between SLE patients and healthy controls.

    Cryptococcus neoformans is the third most common cause of invasive fungal infections in solid organ transplantation. The infection generally presents as disseminated disease, involving multiple sites including the central nervous system, lungs, and skin. An increase in the incidence of primary pulmonary cryptococcal infections has been reported recently in solid organ recipients; these infections were generally symptomatic with an accelerated clinical course. We report four cases of asymptomatic pulmonary cryptococcosis in solid organ recipients (kidney, n=2, heart, n=2). In each case, an incidental finding on a routine chest radiograph led to the microbiological or histopathological diagnosis of invasive pulmonary C. neoformans infection. In these patients, cryptococcosis occurred a median of 25 months (range 7-36 months) after organ transplantation. All patients had a calcineurin inhibitor, prednisone, and azathioprine or mycophenolate mofetil as part of their immunosuppressive therapy at the time of diagnosis. Serum cryptococcal antigen was available and positive in the three patients studied; assessment of cerebrospinal fluid (CSF) of all four patients revealed no organisms by smear or culture. Therapy consisted of oral fluconazole in all cases, with flucytosine in one case, combined with resection of lung tissue in two individuals. All patients have remained free of cryptococcal disease (follow-up median 42 months, from 18 to 88 months). Cryptococcal disease in solid organ recipients may present as asymptomatic, localized pulmonary disease. The natural history of such infections is unknown. New pulmonary radiographic findings should prompt an aggressive diagnostic evaluation including serum and CSF cryptococcal antigen assays, and a biopsy of pulmonary lesions. Prolonged therapy may be used to reduce the risk of progression and dissemination during periods of intensified immune suppression.

  18. Clinical, immunopathologic, and therapeutic considerations of inflammatory myopathies.

    The inflammatory myopathies encompass a group of heterogenous muscle diseases which have in common an acquired myopathy with histological signs of endomysial inflammation. We present evidence based on recently emerged clinical, histologic, immunopathologic, demographic and therapeutic observations that these myopathies comprise three major and distinct groups: polymyositis (PM), dermatomyositis (DM), and inclusion-body myositis (IBM). Immune-mediated mechanisms characteristic for each group appear to play a primary role in the pathogenesis of these diseases. In DM there is an intramuscular microangiopathy mediated by the C5b-9 membranolytic attack complex, leading sequentially to loss of capillaries, muscle ischemia, muscle fiber necrosis and perifascicular atrophy. In contrast, in PM and IBM the muscle fiber injury is initiated by sensitized CD8+ cytotoxic T cells that recognize MHC-I restricted muscle antigens, leading to phagocytosis and fiber necrosis. Among the viruses implicated in the cause of inflammatory myopathies, only the retroviruses, HIV, HTLV-1 and simian retroviruses, have been convincingly associated with PM. Retroviruses, therefore, appear to be the leading group of viruses capable of triggering these diseases. The treatment of inflammatory myopathies has been largely empirical. A detailed therapeutic plan based on our experience with a large number of patients is presented. Patients with bona fide PM or DM respond to steroids to some degree and for some period of time. In contrast, patients with IBM do not respond to any therapy and the disease should be suspected when a patient with presumed PM has failed treatment. Methotrexate and cyclophosphamide are disappointing. Cyclosporine and Azathioprine are commonly used but they are of uncertain benefit. Plasmapheresis is ineffective. High-dose intravenous immunoglobulin is a promising new therapeutic modality.

    Full Text Available Abstract Neuro-Behçet’s disease (NBD involves the central nervous system; peripheral nervous system involvement is not often reported. NBD is quite common in adult patients and occurs rarely during childhood and adolescence. Young patients may share symptoms and signs of NBD with other neuro-ophthalmological disorders (e.g. idiopathic intracranial hypertension; thus, making the differential diagnosis difficult. Neuroimaging is mandatory and necessary for a correct NBD diagnosis but in children radiological examinations are often difficult to perform without sedation. From 1971 to 2011, 130 patients aged ≤16 years have been reported with NBD, according to retrospective surveys, case series, and case reports. The origin of the reported cases met the well-known geographical distribution of Behçet’s disease (BD; the mean age at presentation of neurological findings was 11.8 years, with male gender prevalence (ratio, 2.9:1. We considered in detail the neuro-ophthalmological features of the 53 cases whose neuroimaging alterations were described with an assigned radiological pattern of the disease (parenchymal: 14 cases, non-parechymal: 35 cases, and mixed: 4 cases. In 19/53 patients (36%, neuro-ophthalmological symptoms anticipated any pathognomonic sign for a BD diagnosis, or only occasional aphtae were recalled by the patients. Family history was positive in 17% of subjects. Headache was reported in 75% of the patients; in those presenting with cerebral vascular involvement, headache was combined to other symptoms of intracranial hypertension. Papilledema was the most frequently reported ophthalmological finding, followed by posterior uveitis. Treatment consisted of systemic steroids in 93% of patients, often combined with other immunosuppressive drugs (especially colchicine and azathioprine. Clinical recovery or improvement was documented in the large majority of patients. Nine subjects had definitive alterations, and one died. Based on our
