    Intravenous immunoglobulin (IVIG) has been used as antibody replacement therapy in primary immunodeficiency diseases (PIDDs) for more than 50 years. Its role as a therapeutic agent has expanded over the past couple of decades as its anti-inflammatory and immune-modulatory mechanisms of action have been elucidated. It is now used "off-label" to treat other autoimmune diseases. This article focuses on the role of IVIG in the treatment of PIDDs characterized by absent or deficient antibody production. Replacement doses are given on a monthly basis in these conditions as a prophylactic measure to prevent acute and serious bacterial infections. [Pediatr Ann. 2017;46(1):e8-e12.].

    Full Text Available Mohamed Mahdi-Rogers, Yusuf A RajaballyNeuromuscular Clinic, Department of Neurology, University Hospitals of Leicester, Leicester, UKAbstract: Chronic inflammatory demyelinating polyneuropathy (CIDP is an acquired heterogeneous disorder of immune origin affecting the peripheral nerves, causing motor weakness and sensory symptoms and signs. The precise pathophysiology of CIDP remains uncertain although B and T cell mechanisms are believed to be implicated. Intravenous immunoglobulins (IVIg have been shown in a number of trials to be an effective treatment for CIDP. IVIg is thought to exert its immunomodulatory effects by affecting several components of the immune system including B-cells, T-cells, macrophages and complement. This article provides an overview of the pathogenesis of CIDP and of its treatment with IVIg.Keywords: chronic inflammatory demyelinating polyneuropathy, intravenous immunoglobulin, pathogenesis, treatment

    Full Text Available Scleroderma is progressive autoimmune disease associated with severe disability. The major underlying pathological process in scleroderma is progressive development of fibrous tissue and obliteration of the microvasculature. Currently, there are no medical products for the treatment of scleroderma that provide both sufficient immunosuppression and low-risk side safety profile with negligible side effects. There are a large number of experimental data showing that intravenous immunoglobulin (IVIG has multiple clinical and morphological effects. On the other hand, some authors report good effect of intravenous immune globulins in patients with scleroderma. The less frequent side effects of IVIG in doses below or equal to 2 g/kg/month divided in 5 consecutive days make IVIG a promising treatment of choice in scleroderma.

    Gait impairment is a common presenting symptom in patients with chronic inflammatory demyelinating polyneuropathy (CIDP). However, gait parameters have not previously been evaluated in detail as potential independent outcome measures. We prospectively measured changes in spatiotemporal gait parameters of 20 patients with CIDP at baseline and following treatment with intravenous immunoglobulin (IVIG), using GAITRite® a computerized walkway system with embedded sensors. Overall, study patients showed significant improvements in gait velocity, cadence, stride length, double support time, stance phase, and swing phase following IVIG treatment. Mean changes in velocity, stance phase, and swing phase, exhibited the greatest statistical significance among the subgroup that exhibited clinically meaningful improvement in Inflammatory Neuropathy Cause and Treatment disability score, Medical Research Council sum score, and grip strength. Assessment of gait parameters, in particular velocity, step phase and swing phase, is a potentially sensitive outcome measure for evaluating treatment response in CIDP.

An atypical clinical presentation with cutaneous and subcutaneous nodules has been reported rarely. In recent years, intravenous immunoglobulin (IVIg appears to be the therapy of choice for scleromyxedema. Treatment experiences in atypical manifestations with mucinous nodules are limited to sporadic reports. We report the case of male patient with atypical scleromyxedema without underlying paraproteinemia, presenting with generalized papular and sclerodermoid skin eruption and multiple nodular mucinous lesions on the fingers and face as well as on the eyelids, and associated systemic symptoms. Complete regression of all cutaneous lesions and extracutaneous symptoms with sustained remission was achieved by combined treatment with thalidomide and IVIg.

    Full Text Available Intravenous immunoglobulin (IVIG is used in the treatment of neuropathy. This case report presents, for the first time, a patient with severe periodontal destruction after chronic therapy with IVIG. The patient reported having extracted his maxillary anterior teeth himself due to high mobility. Clinical examination and radiographic images show a generalized and severe periodontitis. No significant alterations in genetic or microbiological features were observed. The present case suggests that periodontal disease aggravation could be considered a new adverse effect of IVIG therapy. Postulated mechanisms are immune complexes formation, complement activation, and a direct effect in osteoclasts. In conclusion, it is important that patients that will receive IVIG treatment underwent dental evaluation.

    The management of refractory recurrent pericarditis is challenging. Previous clinical reports have noted a beneficial effect of high-dose intravenous human immunoglobulins (IvIgs) in isolated and systemic inflammatory disease-related forms. In this article, we analyzed retrospectively our clinical experience with IvIg therapy in a series of clinical cases of pericarditis refractory to conventional treatment. We retrospectively analyzed 9 patients (1994 to 2010) with refractory recurrent pericarditis, who received high-dose IvIg as a part of their medical treatment. Nonsteroidal anti-inflammatory drugs (NSAIDs), steroids, or colchicine treatment was not discontinued during IvIg treatment. No patients had a history of autoimmune or connective tissue diseases. During an average period of 11 months from the first recurrence, patients had experienced a mean of 5 relapses before the first IvIg treatment. In 4 cases, patients showed complete clinical remission with no further relapse after the first IvIg cycle. Two patients experienced a single minor relapse, responsive to short-term nonsteroidal anti-inflammatory drugs. In 2 patients, we performed a second cycle of IvIg after a recurrence of pericarditis, with subsequent complete remission. One patient did not respond to 3 cycles of IvIg and subsequently underwent pericardial window and long-term immunosuppressive treatment. No major adverse effect was observed in consequence of IvIg administration in all the cases. In conclusion, although IvIg mode of action is still poorly understood in this setting, this treatment can be considered as an option in patients with recurrent pericarditis refractory to conventional medical treatment and, in our small series, has proved to be effective in 8 of 9 cases.

    Intravenous Immunoglobulin G (IVIG) therapy has been used as a component of the treatment of hemolytic disease of the newborn. There is still no consensus on its use in ABO hemolytic disease of the newborn routinely. The aim of this study is to determine whether administration of IVIG to newborns with ABO incompatibility is necessary. One hundred and seventeen patients with ABO hemolytic disease and positive Coombs test were enrolled into the study. The subjects were healthy except jaundice. Infants were divided into two groups: Group I (n = 71) received one dose of IVIG (1 g/kg) and LED phototherapy whereas Group II (n = 46) received only LED phototherapy. One patient received erythrocyte transfusion in Group I, no exchange transfusion was performed in both groups. Mean duration of phototherapy was 3.1 ± 1.3 days in Group I and 2.27 ± 0.7 days in Group II (p hemolytic disease. Meticulus follow-up of infants with ABO hemolytic disease and LED phototherapy decreases morbidity. IVIG failed to show preventing hemolysis in ABO hemolytic disease.

    Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease with diverse manifestations. We suggest that intravenous immunoglobulin (IVIg) therapy may be beneficial and safe for various manifestations in SLE. A structured literature search of articles published on the efficacy of IVIg in the treatment of SLE between 1983 and 2005 was conducted. We searched the terms "IVIg," "intravenous immunoglobulin," "lupus," "SLE," and "systemic lupus erythematosus." The various clinical manifestations of SLE that were reported to be successfully treated by IVIg in case reports include autoimmune hemolytic anemia, acquired factor VIII inhibitors, acquired von Willebrand disease, pure red cell aplasia, thrombocytopenia, pancytopenia, myelofibrosis, pneumonitis, pleural effusion, pericarditis, myocarditis, cardiogenic shock, nephritis, end-stage renal disease, encephalitis, neuropsychiatric lupus, psychosis, peripheral neuropathy, polyradiculoneuropathy, and vasculitis. The most extensive experience is with lupus nephritis. There are only a few case series of IVIg use in patients with SLE with various manifestations, in which the response rate to IVIg therapy ranged from 33 to 100%. We suggest that IVIg devoid of sucrose, at a dose of 2 g/kg over a 5-d period given uniformly and at a slow infusion rate in patients without an increased risk for thromboembolic events or renal failure, is a safe and beneficial adjunct therapy for cases of SLE that are resistant to or refuse conventional treatment. The duration of therapy is yet to be established. Controlled trials are warranted.

  17. Solar urticaria successfully treated with intravenous immunoglobulin.

    2012-02-01

    Idiopathic solar urticaria (SU) is a rare, debilitating photodermatosis, which may be difficult to treat. First-line treatment with antihistamines is effective in mild cases, but remission after phototherapeutic induction of tolerance is often short-lived. Other treatment options include plasma exchange, photopheresis and cyclosporin. We present two cases of severe, idiopathic SU, which were resistant to conventional treatment. Both patients achieved remission after administration of intravenous immunoglobulin (IVIg) and have remained in remission at 13 months and 4 years, respectively. There are only two case reports of successful treatment of solar urticaria with IVIg. In our experience IVIg given at a total dose of 2 g\\/kg over several 5-day courses about a month apart is an effective treatment option for severe idiopathic SU. It is also generally safe, even if certainly subject to significant theoretical risks, such as induction of viral infection or anaphylaxis.

  18. FCGR2A Promoter Methylation and Risks for Intravenous Immunoglobulin Treatment Responses in Kawasaki Disease

    2015-01-01

    Full Text Available Kawasaki disease (KD is characterized by pediatric systemic vasculitis of an unknown cause. The low affinity immunoglobulin gamma Fc region receptor II-a (FCGR2A gene was reported to be involved in the susceptibility of KD. DNA methylation is one of the epigenetic mechanisms that control gene expression; thus, we hypothesized that methylation status of CpG islands in FCGR2A promoter associates with the susceptibility and therapeutic outcomes of Kawasaki disease. In this study, 36 KD patients and 24 healthy subjects from out-patient clinic were recruited. Eleven potential methylation sites within the targeted promoter region of FCGR2A were selected for investigation. We marked the eleven methylation sites from A to K. Our results indicated that methylation at the CpG sites G, H, and J associated with the risk of KD. CpG sites B, C, E, F, H, J, and K were found to associate with the outcomes of IVIG treatment. In addition, CpG sites G, J, and K were predicted as transcription factors binding sites for NF-kB, Myc-Max, and SP2, respectively. Our study reported a significant association among the promoter methylation of FCGR2A, susceptibility of KD, and the therapeutic outcomes of IVIG treatment. The methylation levels of CpG sites of FCGR2A gene promoter should be an important marker for optimizing IVIG therapy.

    1995-07-01

    In this uncontrolled study 15 patients with ANCA-associated systemic vasculitis, who were poor responders to conventional therapy, were treated with single or multiple courses of intravenous immunoglobulin (IVIG), 30 g/day over 5 days. Clinical and serological evaluation was performed before and 4 weeks after IVIG. Six of the 15 patients experienced clinically significant benefit from IVIG. Improvement was confined to single organ manifestations (skin, ENT findings), no improvement was seen with conjunctivitis and scleritis, pericarditis or nephritis. No patient experienced complete remission after IVIG. Repeated courses of IVIG at 4-week intervals were no more effective than single courses. In six anti-proteinase 3 (PR3)-positive patients pretreatment sera were incubated with F(ab')2 fragments of the IVIG preparation in vitro to measure the inhibitory effect of IVIG on anti-PR3 activity. An inhibition of anti-PR3 activity by 25-70% was observed; this did not correlate with clinical effects. Approximately 40% of patients benefited from IVIG treatment, though complete remission of disease activity did not occur. Neither clinical characteristics nor the inhibitory effect of the IVIG preparation on serum anti-PR3 activity in vitro predicted clinical response to this treatment modality.

    Full Text Available La sindrome di Churg-Strauss è una malattia estremamente rara e ancora più raro è riscontrarla in una paziente in stato di gravidanza. Il trattamento iniziale della malattia consiste nella somministrazione di alte dosi di corticosteroidi. I pazienti più gravi o che rispondono poco o insoddisfacientemente ai corticosteroidi vengono solitamente trattati con farmaci citotossici. Le immunoglobuline somministrate per via endovenosa (IgEV stanno dimostrando di essere efficaci nel trattamento di questa patologia, tuttavia non esiste un consenso universale sulla loro effettiva utilità nelle vasculiti sistemiche. Noi presentiamo il caso di una donna con sindrome di Churg-Strauss resistente al trattamento con corticosteroidi e ciclofosfamide. Allorché si riscontrò che la paziente era al 3° mese di gravidanza fu iniziata una terapia con alte dosi di IgEV con ottimi risultati. Questo caso conferma l’utilità del trattamento con IgEV della sindrome di Churg-Strauss e ne dimostra l’efficacia anche in stato di gravidanza.

    Although intravenous immunoglobulin (IVIG) is highly effective in Kawasaki disease (KD), mechanisms are not understood and 10-20% of patients are treatment-resistant, manifesting a higher rate of coronary artery aneurysms. Murine models suggest that α2-6-linked sialic acid (α2-6Sia) content of IVIG is critical for suppressing inflammation. However, pro-inflammatory states also up-regulate endogenous levels of β-galactoside:α2-6 sialyltransferase-I (ST6Gal-I), the enzyme that catalyzes addition of α2-6Sias to N-glycans. We asked whether IVIG failures correlated with levels of α2-6Sia on infused IVIG or on the patient's own endogenous IgG. We quantified levels of α2-6Sia in infused IVIG and endogenous IgG from 10 IVIG-responsive and 10 resistant KD subjects using multiple approaches. Transcript levels of ST6GAL1, in patient whole blood and B cell lines were evaluated by RT-PCR. Plasma soluble (s)ST6Gal-I levels were measured by ELISA. There was no consistent difference in median sialylation levels of infused IVIG between groups. However, α2-6Sia levels in endogenous IgG, ST6GAL1 transcript levels, and ST6Gal-I protein in serum from IVIG-resistant KD subjects were lower than in responsive subjects at both pre-treatment and one-year time points (p treatment response in KD. Rather, lower sialylation of endogenous IgG and lower blood levels of ST6GALI mRNA and ST6Gal-I enzyme predict therapy resistance. These differences were stable over time, suggesting a genetic basis. Because IVIG-resistance increases risk of coronary artery aneurysms, our findings have important implications for the identification and treatment of such individuals.

    Two small trials suggest that low-dose intravenous immunoglobulin (IVIg) may improve the symptoms of complex regional pain syndrome (CRPS), a rare posttraumatic pain condition. To confirm the efficacy of low-dose IVIg compared with placebo in reducing pain during a 6-week period in adult patients who had CRPS from 1 to 5 years. 1:1 parallel, randomized, placebo-controlled, multicenter trial for 6 weeks, with an optional 6-week open extension. Patients were randomly assigned to 1 of 2 study groups between 27 August 2013 and 28 October 2015; the last patient completed follow-up on 21 March 2016. Patients, providers, researchers, and outcome assessors were blinded to treatment assignment. (ISRCTN42179756). 7 secondary and tertiary care pain management centers in the United Kingdom. 111 patients with moderate or severe CRPS of 1 to 5 years' duration. IVIg, 0.5 g/kg of body weight, or visually indistinguishable placebo of 0.1% albumin in saline on days 1 and 22 after randomization. The primary outcome was 24-hour average pain intensity, measured daily between days 6 and 42, on an 11-point (0- to 10-point) rating scale. Secondary outcomes were pain interference and quality of life. The primary analysis sample consisted of 108 eligible patients, 103 of whom had outcome data. Mean (average) pain scores were 6.9 points (SD, 1.5) for placebo and 7.2 points (SD, 1.3) for IVIg. The adjusted difference in means was 0.27 (95% CI, -0.25 to 0.80; P = 0.30), which excluded the prespecified, clinically important difference of -1.2. No statistically significant differences in secondary outcomes were found between the groups. In the open extension, 12 of the 67 patients (18%) who received 2 IVIg infusions had pain reduction of at least 2 points compared with their baseline score. Two patients in the blinded phase (1 in the placebo and 1 in the IVIg group) and 4 in the open IVIg phase had serious events. Results do not apply to patients who have had CRPS for less than 1 year or more

    Kawasaki disease (KD) is a systemic vasculitis primarily affecting children who are initial IVIG treatment. This study was conducted to investigate the risk factors for initial IVIG treatment failure in KD. Children who met KD diagnosis criteria and were admitted for IVIG treatment were retrospectively enrolled for analysis. Patients were divided into IVIG-responsive and IVIG-resistant groups. Initial laboratory data before IVIG treatment were collected for analysis. A total of 131 patients were enrolled during the study period. At 48 h after completion of initial IVIG treatment, 20 patients (15.3%) had an elevated body temperature. Univariate analysis showed that patients who had initial findings of high neutrophil count, abnormal liver function, low serum albumin level (≤2.9 g/dL) and pericardial effusion were at risk for IVIG treatment failure. Multivariate analysis with a logistic regression procedure showed that serum albumin level was considered the independent predicting factor of IVIG resistance in patients with KD (p = 0.006, OR = 40, 95% CI: 52.8-562). There was no significant correlation between age, gender, fever duration before IVIG treatment, haemoglobin level, total leucocyte and platelet counts, C-reactive protein level, or sterile pyuria and initial IVIG treatment failure. The specificity and sensitivity for prediction of IVIG treatment failure in this study were 96% and 34%, respectively. Pre-IVIG treatment serum albumin levels are a useful predictor of IVIG resistance in patients with KD. © 2010 The Author(s)/Journal Compilation © 2010 Foundation Acta Paediatrica.

    The clinical significance of platelet associated IgG in ITP detected by direct platelet suspension immunofluorescence test (PSIFT) was studied. The platelet mean life span (MLS) was measured with 111 In-labelled platelets in 17 adult patients. All the patients had shortened platelet MLS. The direct PSIFT was positive in 14 patients. Patients were initially treated with prednisone; 12 patients with poor response to the drug were splenectomised. 8 of these 12 patients were treated with intravenous immunoglobulin (IvIg) before splenectomy. The response to IvIg was as good or better in the 3 patients with negative PSIFT, than in the 5 patients with positive PSIFT. (author)

    Conclusion: The results of this study suggest that although IVIG treatment within 10 days is important to minimize development of cardiac pathology, neither occurrence of CA lesions in IVIG-treated children nor the time frame for resolution of established CA abnormalities was associated with the timing of IVIG administration. Age 40 mm/hour predict a delay in resolution of CA lesions among children with KD.

    Full Text Available Background/Aim. Intravenous immunoglobulin is a blood product made of human polyclonal immunoglobulin G. The mode of action of intravenous immunoglobulin is very complex. It is indicated in treatment of neonatal immune thrombocytopenia and haemolytic disease of the newborn. The aim of the study was to present our experience in the use of intravenous immunoglobulin in a group of term neonates. Methods. We analysed all relevant clinical and laboratory data of 23 neonates who recieved intravenous immunoglobulin during their hospitalization in Neonatal Intensive Care Unit of Mother and Child Health Care Institute over a five year period, from 2006. to 2010. Results. There were 11 patients with haemolytic disease of the newborn and 12 neonates with immune thrombocytopenia. All of them recieved 1-2 g/kg intravenous immunoglobulin in the course of their treatment. There was no adverse effects of intravenous immunoglobulin use. The use of intravenous immunoglobulin led to an increase in platelet number in thrombocytopenic patients, whereas in those with haemolytic disease serum bilirubin level decreased significantly, so that some patients whose bilirubin level was very close to the exchange transfusion criterion, avoided this procedure. Conclusion. The use of intravenous immunoglobulin was shown to be an effective treatment in reducing the need for exchange transfusion, duration of phototherapy and the length of hospital stay in neonates with haemolytic disease. When used in treatment of neonatal immune thrombocytopenia, it leads to an increase in the platelet number, thus decreasing the risk of serious complications of thrombocytopenia.

However, pro-inflammatory states also up-regulate endogenous levels of β-galactoside:α2-6 sialyltransferase-I (ST6Gal-I, the enzyme that catalyzes addition of α2-6Sias to N-glycans. We asked whether IVIG failures correlated with levels of α2-6Sia on infused IVIG or on the patient's own endogenous IgG.We quantified levels of α2-6Sia in infused IVIG and endogenous IgG from 10 IVIG-responsive and 10 resistant KD subjects using multiple approaches. Transcript levels of ST6GAL1, in patient whole blood and B cell lines were evaluated by RT-PCR. Plasma soluble (sST6Gal-I levels were measured by ELISA.There was no consistent difference in median sialylation levels of infused IVIG between groups. However, α2-6Sia levels in endogenous IgG, ST6GAL1 transcript levels, and ST6Gal-I protein in serum from IVIG-resistant KD subjects were lower than in responsive subjects at both pre-treatment and one-year time points (p <0.001, respectively.Our data indicate sialylation levels of therapeutic IVIG are unrelated to treatment response in KD. Rather, lower sialylation of endogenous IgG and lower blood levels of ST6GALI mRNA and ST6Gal-I enzyme predict therapy resistance. These differences were stable over time, suggesting a genetic basis. Because IVIG-resistance increases risk of coronary artery aneurysms, our findings have important implications for the identification and treatment of such individuals.

    Amyloid-beta peptide (Abeta) contributes to the acute progression of Alzheimer's disease (AD) and has become the main target for therapeutics. Active immunization with Abeta in individuals with AD has been efficacious; however, some patients developed side effects, possibly related to an autoimmune response. Evidence that intravenous immunoglobulin (IVIg), an FDA-approved purified immunoglobulin fraction from normal human donor blood, shows promise of passive immunotherapy for AD is reviewed. Investigations into the molecular effects of IVIg on Abeta clearance, using the BV-2 cellular microglia line, demonstrate that IVIg dissolves Abeta fibrils in vitro, increases cellular tolerance to Abeta, enhances microglial migration toward Abeta deposits, and mediates phagocytosis of Abeta. Preliminary clinical results indicate that IVIg, which contains natural antibodies against the Abeta, warrants further study into its potential to deliver a controlled immune attack on the peptide, avoiding the immune toxicities that have had a negative impact on the first clinical trials of vaccine against Abeta.

    Anti-E alloimmunisation is a less common cause of haemolytic disease in the newborn (HDN) and is usually associated with mild to moderate clinical manifestations, that are often less severe than anti-D immunisation. Conventional treatments for HDN are phototherapy and exchange transfusion, the latter still representing a high-risk procedure. Currently, intravenous immunoglobulin has been used as alternative treatment for HDN to reduce the need for exchange transfusion, as well as the length of phototherapy and hospitalisation. We report a case of anti-E HDN treated successfully with intravenous immunoglobulin, as adjuvant treatment to phototherapy.

    Full Text Available Background Glucose-6-phosphate dehydrogenase deficiency alone or concomitant with ABO isoimmunisation is a widespread indication for neonatal exchange transfusion. Aims To evaluate the effectiveness of Intravenous Immunoglobulin in the treatment of neonatal hyperbilirubinemia due to glucose-6-phosphate dehydrogenase deficiency. Methods A retrospective cohort study was conducted between 2006 and 2014 at the Jordan University of Science and technology. The medical records of 43 infants admitted to the neonatal intensive care unit for isolated glucose-6- phosphate dehydrogenase deficiency hemolytic disease of the newborns were reviewed. Patients were divided into two groups. Group I, a historical cohort, included newborns born between 2006 and 2010, Treatment included phototherapy and exchange transfusion. Group II included newborns born between 2011 and 2014, where, in addition to phototherapy, intravenous immunoglobulin was administered. The duration of phototherapy and number of exchange transfusions were evaluated. Results Of 412 newborns that were admitted with neonatal hyperbilirubinemia, Glucose-6-phosphate dehydrogenase deficiency was present in 43. Of these, 22, did not receive intravenous immunoglobulin and served as a control group. The other 21 newborns received intravenous immunoglobulin. There was no difference in the demographic characteristics between the two groups. Infants in the control group were significantly more likely to receive exchange blood transfusion than infants in the immunoglobulin treatment group, but were significantly less likely to need phototherapy. Conclusion Intravenous immunoglobulin is an effective alternative to exchange transfusion in infants with glucose-6-phosphate dehydrogenase deficiency hemolytic disease of the newborn. It is suggested that intravenous immunoglobulin may be beneficial as a prophylaxis for infants with hyperbilirubinemia.

    Previous research has found patients with the FcγRIIIB NA1 variant having increased risk of intravenous immunoglobulin (IVIG) resistance in Kawasaki disease (KD). Our previous studies revealed that elevated FcγRIIA expression correlated with the susceptibility of KD patients. We conducted this research to determine whether and how Fcγ receptors affect the susceptibility, IVIG treatment response, and coronary artery lesions (CAL) of KD patients. The activating FcγRIIA and inhibitory FcγRIIB methylation levels of seven patients with KD and four control subjects were examined using HumanMethylation27 BeadChip. We enrolled a total of 44 KD patients and 10 control subjects with fevers. We performed real-time RT-PCR to determine the FcγRIIA and FcγRIIB expression levels, as well as a luciferase assay of FcγRIIA. We found a considerable increase in methylation of both FcγRIIA and FcγRIIB in KD patients undergoing IVIG treatment. Promoter methylation of FcγRIIA inhibited reporter activity in K562 cells using luciferase assay. The FcγRIIB mRNA expression levels were not found to increase susceptibility, CAL formation, or IVIG resistance. FcγRIIA mRNA expression levels were significantly higher in IVIG-resistant patients than in those that responded to IVIG during the pre-treatment period. Furthermore, the FcγRIIA/IIB mRNA expression ratio was considerably higher in KD patients with CAL than in those without CAL. FcγRIIA and FcγRIIB both demonstrated increased methylation levels in KD patients that underwent IVIG treatment. FcγRIIA expression influenced the IVIG treatment response of KD patients. The FcγRIIA/IIB mRNA expression ratio was greater in KD patients with CAL formation. PMID:27893416

    Cytomegalovirus (CMV) remains one of the most important pathogens after transplantation, potentially leading to CMV disease, allograft dysfunction, acute, and chronic rejection and opportunistic infections. Immunoglobulin G (IgG) preparations with high antibody titers against CMV are a valuable adjunctive prevention and treatment option for clinicians and apart from standard intravenous immunoglobulin (IVIG), CMV hyperimmune preparations are available. The CMV antibody titer of these preparations is typically determined by Enzyme-linked immunosorbent assay (ELISA), also used for the selection of high titer plasma donors for the production of the CMV Hyperimmune product. However, CMV ELISA titers do not necessarily correlate with CMV antibody function which is determined by virus neutralization tests. CMV antibody titers were determined by both ELISA and virus neutralization assay and the IgG subclass distribution was compared between a CMV hyperimmune licensed in Europe and standard IVIG preparations. Although the expected high CMV IgG ELISA antibody titers were confirmed for three lots of a CMV hyperimmune preparation, the functionally more relevant CMV neutralizing antibody titers were significantly higher for 31 lots of standard IVIG preparations. Moreover, considerably lower IgG3 levels were found for the CMV hyperimmune preparation compared with standard IVIG preparations. The higher functional CMV neutralization titers of standard IVIG preparations and the better availability of these preparations, suggest that these products could be a valuable alternative to the CMV hyperimmune preparation.

    To evaluate whether the use of intravenous immunoglobulin in newborn infants with isoimmune hemolytic jaundice due to Rh and ABO incompatibility is an effective treatment in reducing the need for exchange transfusion. This study included all direct Coombs' test positive Rh and ABO isoimmunized babies, who admitted in the Neonatal Intensive Care Unit of Ghaem Hospital of Mashhad University of Medical Sciences, Iran, from October 2003 to October 2004. Significant hyperbilirubinemia was defined as rising by >or=0.5 mg/dl per hour. Babies were randomly assigned to received phototherapy with intravenous immunoglobulin (IVIg) 0.5 g/kg over 4 hours, every 12 hours for 3 doses (study group) or phototherapy alone (control group). Exchange transfusion was performed in any group if serum bilirubin exceeded >or=20mg/dl or rose by >or=1mg/dl/h. A total of 34 babies were eligible for this study (17 babies in each group). The number of exchange transfusion, duration of phototherapy and hospitalization days, were significant shorter in the study group versus control group. When we analyzed the outcome results in ABO and Rh hemolytic disease separately, the efficacy of IVIg was significantly better in Rh versus ABO isoimmunization. Late anemia was more common in the IVIg group 11.8% versus 0%, p=0.48. Adverse effects were not observed during IVIg administration. Administration of IVIg to newborns with significant hyperbilirubinemia due to Rh hemolytic disease reduced the need for exchange transfusion but in ABO hemolytic disease there was no significant difference between IVIg and double surface blue light phototherapy.

    Intravenous immunoglobulin (IVIg) therapy has multiple mechanisms of immunomodulatory action. We wished therefore to assess its efficacy in a spectrum of patients with refractory uveitis. Retrospective review of clinical charts was conducted to document response to IVIg treatment in consecutive patients with treatment-refractory uveitis. Main outcome measures were control of intraocular inflammation, visual acuity, progression of the disease, and complications. Four (two male) patients, with a mean age at the beginning of the treatment of 47 years (range: 39-64), were included in the study. Indication for treatment was patients with active non-infectious uveitis refractory to steroids and immunomodulatory therapy. All patients received a course of 0.5 g/kg per day of IVIg for three consecutive days, repeating this course at a mean of 11 week (range: 2-39 weeks) intervals when indicated clinically. The median duration of the IVIg therapy was 7 months (range: 3-14 months). In three patients treatment resulted in stabilisation and prevention of progression of the disease, and additionally in two patients it facilitated a decrease in prednisolone dose. Treatment failed to induce long-term remission in one patient with recurrence of macular oedema. IVIg was well tolerated with neither immediate nor longer-term adverse events observed. In three out of four cases IVIg was an effective adjunctive therapy and well tolerated for the management of treatment-refractory uveitis.

    Intravenous immunoglobulin (IVIg) therapy is currently the only established treatment in patients with multifocal motor neuropathy (MMN), and many patients have an IVIg-dependent fluctuation. We aimed to investigate the efficacy and safety of every 3 week IVIg (1.0 g/kg) for 52 weeks. This study was an open-label phase 3 clinical trial, enrolling 13 MMN patients. After an induction IVIg therapy (0.4 g/kg/d for 5 consecutive days), maintenance dose (1.0 g/kg) was given every 3 weeks for 52 weeks. The major outcome measures were the Medical Research Council (MRC) sum score and hand-grip strength at week 52. This trial is registered with ClinicalTrials.gov, number NCT01827072. At week 52, 11 of the 13 patients completed the study, and all 11 had a sustained improvement. The mean (SD) MRC sum score was 85.6 (8.7) at the baseline, and 90.6 (12.8) at week 52. The mean grip strength was 39.2 (30.0) kPa at the baseline and 45.2 (32.8) kPa at week 52. Two patients dropped out because of adverse event (dysphagia) and decision of an investigator, respectively. Three patients developed coronary spasm, dysphagia, or inguinal herniation, reported as the serious adverse events, but considered not related with the study drug. The other adverse effects were mild and resolved by the end of the study period. Our results show that maintenance treatment with 1.0 g/kg IVIg every 3 week is safe and efficacious for MMN patients up to 52 weeks. Further studies are required to investigate optimal dose and duration of maintenance IVIg for MMN. © 2018 The Authors.

    Full Text Available Abstract Background Expression of inflammatory cytokines in cerebrospinal fluid (CSF has led to the hypothesis of intrathecal chronic inflammation to explain the denervation observed in post-polio syndrome (PPS. It has been shown that therapy with intravenous immunoglobulin (IVIG improves physical performance and dampens down the inflammatory process at 6 months in PPS patients. We here examined the effects of IVIG on cytokine expression and clinical outcome one year after IVIG treatment. Methods From a previous study with 135 PPS patients included, 41 patients were further evaluated before un-blinding for one year (21 placebo and 20 treated with IVIG, Xepol® 50 mg/ml, and were assessed for clinical variables by performing the Short Form-36 survey (SF-36 questionnaire assessment, the 6 minute walk distance test (6MWT and registering pain level by Visual Analogue Scale (VAS after IVIG treatment. A separate cohort of 37 PPS patients went through lumbar puncture (LP at baseline and 20 patients, treated with IVIG, repeated the LP one year later. Thirty patients affected with other neurological diseases (OND were used as control group. Inflammatory cytokines TNF, TGFβ, IFNγ, IL-23, IL-13 and IL-10 were measured in blood cells and CSF cells with RT-PCR. Results Scores of the physical components of SF-36 were significantly higher at the one year follow up time-point in the IVIG-treated patients when compared to baseline as well as to the control subjects. Pain VAS score and 6MWT improved significantly in the IVIG-treated patients when compared with baseline Relative expression of TNF and IFN-γ in both PBMCs and CSF from PPS patients were increased compared to OND subjects at baseline (p  Conclusions IVIG has effects on relevant QoL variables and inflammatory cytokines up to one year in patients with PPS. This gives a basis for scheduling IVIG in upcoming trials with this therapy.

    Full Text Available Introduction: From its initial report on two female patients in 1979 by J.O. Susac, Susac syndrome (SuS or SICRET (small infarctions of cochlear, retinal and encephalic tissue has persisted as an elusive entity. To date the available evidence for its treatment is based on case reports and case series. The largest systematic review described only 304 reported cases since the 1970s. Here we presented the first reported case to our knowledge in Mexican population and the unusual presentation in a pregnant patient. Case presentation: A 34-year-old Hispanic woman was brought to the ER in our hospital for apathy and behavioral changes. Upon arrival at the ER, her husband described a one-month history of behavioral changes with apathy, progressive abulia, visuospatial disorientation, and gait deterioration. The initial lab test shows no significance except by a positive qualitative hCG. An MRI was obtained and showed hyperintense periventricular white matter lesions in T2 and FLAIR sequences also involving bilateral basal ganglia and with predominant affection of the corpus callosum, in addition to infratentorial cerebellar lesions. After treatment with intravenous immunoglobulins a marked and prompt clinical and radiological improvement was observed. Conclusion: SuS is still an elusive disease. To date, no definitive score or clinical feature can predict the outcome of the disease. The presentation during pregnancy is also rare and therefore the optimal treatment and the prognosis is unknown. We hope that this article will serve as a foundation for future research.

    Full Text Available &lt;b&gt;Purpose:&lt;/b&gt; It has been reported that 10% to 20% of children with Kawasaki disease (KD will not respond to intravenous immunoglobulin (IVIG treatment. In this study, we aimed to identify useful predictors of therapeutic failure in children with KD. &lt;b&gt;Methods:&lt;/b&gt; We examined 309 children diagnosed with KD at the Kyungpook National University Hospital and the Inje University Busan Paik Hospital between January 2005 and June 2011. We retrospectively reviewed their medical records and analyzed multiple parameters in responders and nonresponders to IVIG. &lt;b&gt;Results:&lt;/b&gt; Among the 309 children, 30 (9.7% did not respond to IVIG. They had significantly higher proportion of neutrophils, and higher levels of aspartate aminotransferase, alanine aminotransferase (ALT, total bilirubin, and N-terminal fragment of B-type natriuretic peptide than did responders. IVIGnonresponders had a significantly longer duration of hospitalization, and more frequently experienced coronary artery lesion, and sterile pyuria. No differences in the duration of fever at initial treatment or, clinical features were noted. &lt;b&gt;Conclusion:&lt;/b&gt; Two independent predictors (ALT?#248;4 IU/L, total bilirubin?#240;.9 mg/dL for nonresponse were confirmed through multivariate logistic regression analysis. Thus elevated ALT and total bilirubin levels might be useful in predicting nonresponse to IVIG therapy in children with KD.

  5. Clinical Efficiency of Application of Intravenous Immunoglobulin in Pregnant Women with Intrauterine Infection

    2016-02-01

    Full Text Available The problem of intrauterine infection (IUI is still relevant today. Ineffective treatment of this pathology is associated with physiological decline of the immunity in these patients. We have proposed the additional use of intravenous immunoglobulin for the treatment of pregnant women with IUI. There were examined 75 patients with IUI, which was diagnosed in the II trimester. The I group consisted of 40 individuals who received conventional treatment, the II group was formed from 35 women who additionally received intravenous immunoglobulin. On the background of IUI, pregnancy was characterized by an increased incidence of threatened miscarriage and premature labor, gestosis and placental dysfunction; during delivery, premature rupture of amniotic membrane and fetal distress were more common. These patients had placenta with both ultrasonic and histological signs of infection. Among newborns, there was a significant increase in the incidence of pathology associated with intrauterine infection. Additional use of intravenous immunoglobulin in the treatment of IUI during the II trimester of pregnancy in comparison with conventional therapy leads to a significant reduction in the incidence of both obstetric complications and perinatal pathology.

    1992-01-01

    A case of severe Guillain-Barré syndrome (GBS) was treated with high dose intravenous immunoglobulin (IVIG), 400 mg.kg-1.days-1, over three consecutive days. The treatment was repeated once. We observed a time-related response between immunoglobulins administration and clinical improvement. The pathologic lesions of the GBS suggest that this syndrome has an immunologic basis: a humoral factor is probably not the only immunological mechanism and cellular mechanisms are also likely to be of importance. Specific mechanisms might also be present in GBS, such as anti-idiotypic suppression of autoantibodies, and elimination of circulating immune complexes. Treatment with IVIG might have several therapeutic advantages over plasmapheresis: IVIG is easily infused without any delay, is easily available and has been used widely without serious complications.

  9. THE ROLE OF IgM-ENRICHED INTRAVENOUS IMMUNOGLOBULIN IN TRANSPLANTATION

    Directory of Open Access Journals (Sweden)

    Szabó Judit

    2014-04-01

    Full Text Available After organ transplantation, gamma globulin and intravenous immunoglobulin enriched with IgM are most frequently used in septic shock as early immune-support. If the explanted organ is infected, the transplantation, as a life-saving operation, can be performed if there is no systemic inflammation and the patient receives IgM enriched immunoglobulin prophylaxis during surgery. The period after transplantation can be divided into three parts from the infection point of view: the first month after transplantation, the first sixth months and the following six months. Infections within the first month are basically related to the surgical procedure. Because of the immunosuppressive therapy, the opportunistic and fungal infections are more common during the first sixth months. After this period, the occurrence and the type of infections are similar to that of the non-transplant population except for pulmonary infections. The latter is two to three times more frequent. This is explained by the secondary hypogammaglobulinaemia (lower blood levels of IgM and IgG which is caused by the steroids but most of mycophenolate mofetil by inhibition of the T and B lymphocyte proliferation. Septic shock develops with a continuing fall of IgM levels. Under these circumstances additional intravenous immunoglobulin therapy with IgM can be lifesaving. Besides, immunoglobulin concentrates with IgM may also be used in the case of viral infections without prophylaxis and/or without etiological therapy such as in the case of West Nile virus infection. As a result of the increase in antibiotic resistance, the application of immunotherapy, including immunoglobulins may become the mainstream in the treatment of septic shock.

    Full Text Available Influenza is a highly contagious, acute, febrile respiratory infection that can have fatal consequences particularly in individuals with chronic illnesses. Sporadic reports suggest that intravenous immunoglobulin (IVIg may be efficacious in the influenza setting. We investigated the potential of human IVIg to ameliorate influenza infection in ferrets exposed to either the pandemic H1N1/09 virus (pH1N1 or highly pathogenic avian influenza (H5N1. IVIg administered at the time of influenza virus exposure led to a significant reduction in lung viral load following pH1N1 challenge. In the lethal H5N1 model, the majority of animals given IVIg survived challenge in a dose dependent manner. Protection was also afforded by purified F(ab′2 but not Fc fragments derived from IVIg, supporting a specific antibody-mediated mechanism of protection. We conclude that pre-pandemic IVIg can modulate serious influenza infection-associated mortality and morbidity. IVIg could be useful prophylactically in the event of a pandemic to protect vulnerable population groups and in the critical care setting as a first stage intervention.

    There is a growing interest in new therapeutic strategies for the treatment of Alzheimer disease (AD) which focus on reducing the beta-amyloid peptide (Aβ) burden in the brain by sequestering plasma Aβ, a large proportion of which is bound to albumin and other proteins. This review discusses the concepts of interaction between Aβ and albumin that have given rise to AMBAR (Alzheimer's Disease Management by Albumin Replacement) project, a new multicentre, randomised, controlled clinical trial for the treatment of AD. Results from preliminary research suggest that Albutein(®) (therapeutic albumin, Grifols) contains no quantifiable levels of Aβ. Studies also show that Albutein(®) has Aβ binding capacity. On the other hand, AD entails a high level of nitro-oxidative stress associated with fibrillar aggregates of Aβ that can induce albumin modification, thus affecting its biological functions. Results from the phase ii study confirm that using therapeutic apheresis to replace endogenous albumin with Albutein(®) 5% is feasible and safe in patients with AD. This process resulted in mobilisation of Aβ and cognitive improvement in treated patients. The AMBAR study will test combination therapy with therapeutic apheresis and haemopheresis with the possible leverage effect of Albutein(®) with intravenous immunoglobulin replacement (Flebogamma(®) DIF). Cognitive, functional, and behavioural changes in patients with mild to moderate AD will be assessed. the AMBAR study represents a new therapeutic perspective for AD.

    Full Text Available Nonparaneoplastic opsoclonus–myoclonus ataxia syndrome is a rare neuroinflammatory condition featured by opsoclonus, myoclonus, ataxia, and cognitive behavioral disturbance. The authors report an observation of enterovirus 71-associated opsoclonus–myoclonus ataxia syndrome evolving toward full recovery on intravenous intravenous immunoglobulin (IG treatment. Based on this case report, enterovirus 71 should be added to the list of infectious agents likely involved in opsoclonus–myoclonus ataxia syndrome, including the emerging subgroup of opsoclonus–myoclonus ataxia syndrome recovering without aggressive or prolonged immunosuppressive intervention. Further studies are mandatory to define the precise role, incidence, treatment, and outcome of enterovirus 71 and other infectious agents in benign forms of opsoclonus–myoclonus ataxia syndrome.

    Full Text Available Intravenous immunoglobulins (IVIGs, a mixture of variable amounts of proteins (albumin, IgG, IgM, IgA, and IgE antibodies, as well as salt, sugar, solvents, and detergents, are successfully used to treat a variety of dermatological disorders. For decades, IVIGs have been administered for treatment of infectious diseases and immune deficiencies, since they contain natural antibodies that represent a first-line defense against pathogens. Today their indication has expanded, including the off-label therapy for a variety of autoimmune and inflammatory diseases. In dermatology, IVIGs are administered for treatment of different disorders at different therapeutic regimens, mostly with higher doses then those administered for treatment of infectious diseases. The aim of this prospective review is to highlight the indications, effectiveness, side effects, and perspectives of the systemic treatment with IVIGs for patients with severe, life-threatening, and resistant to conventional therapies autoimmune or inflammatory dermatoses.

    Five patients treated with intraperitoneal 131I-labeled mouse monoclonal antibody for ovarian cancer also received i.v. exogenous polyclonal human anti-murine immunoglobulin antibody. The pharmacokinetics of 131I-labeled monoclonal antibody in these patients were compared with those of 28 other patients receiving i.p.-radiolabeled monoclonal antibody for the first time without exogenous human anti-murine immunoglobulin, and who had no preexisting endogenous human anti-murine immunoglobulin antibody. Patients receiving i.v. human anti-murine immunoglobulin antibody demonstrated a rapid clearance of 131I-labeled monoclonal antibody from their circulation. The (mean) maximum 131I blood content was 11.4% of the injected activity in patients receiving human anti-murine immunoglobulin antibody compared to 23.3% in patients not given human anti-murine immunoglobulin antibody. Intravenous human anti-murine immunoglobulin antibody decreased the radiation dose to bone marrow (from 131I-labeled monoclonal antibody in the vascular compartment) 4-fold. Following the injection of human anti-murine immunoglobulin antibody, 131I-monoclonal/human anti-murine immunoglobulin antibody immune complexes were rapidly transported to the liver. Antibody dehalogenation in the liver was rapid, with 87% of the injected 131I excreted in 5 days. Despite the efficient hepatic uptake of immune complexes, dehalogenation of monoclonal antibody was so rapid that the radiation dose to liver parenchyma from circulating 131I was decreased 4-fold rather than increased. All patients developed endogenous human anti-murine immunoglobulin antibody 2 to 3 weeks after treatment

    Full Text Available Introduction: Direct costs for treating Guillain-Barré Syndrome (GBS represent a significant financial burden to public hospitals. Few studies compared the cost of plasma exchange (PE treatment with human intravenous immunoglobulin (IVIg. Objectives: To compare the cost of two therapies for GBS: IVIg and PE. Secondary objective was to evaluate compliance to IVIg prescription guidelines of the Pharmacy and Therapeutics Committee (PTC. Methods: A cross-sectional study included 25 patients with GBS admitted in a university affiliated hospital from June, 2003 through June, 2008. The costs of IVIg (n=20 and PE (n=5 were evaluated through the cost minimization method, considering direct medical costs yield by the management of the institution. Patients receiving treatments other than PE or IVIg were excluded. Data were collected by medical records review. Clinical endpoint was disability on discharge, established by the 7-point scale of Hughes. Compliance to the PTC guidelines was evaluated considering the dose and prescription regime of IVIg. Results: Twenty-five participants, ranging from 2 to 70 years of age, were included. No difference occurred in any medical variables related to the treatment or in the main clinical outcome measured by the Hughes’ scale. The mean direct cost of PE treatment was US$ 6,059± 1,701 per patient, and the same expense for IVIg was US$ 18,344±12,259 (P = 0.035. Total inpatient cost was US$ 25,730± 18,714 in the PE group, and 34,768± 27,766 (p=0.530 in the IVIg group. Conclusions: In a university-based hospital, PE is equally effective and less expensive than IVIg to treat GBS.

    Full Text Available A 7-year-old girl had presented with high body temperature and joint pain which continued for 3 days. Because of the prolonged history of unexplained fever, rash, bilateral nonpurulent conjunctival injection, oropharyngeal erythema, strawberry tongue, and extreme of age, incomplete Kawasaki disease was considered and started on an intravenous immunoglobulin infusion. Six days after this treatment, patient was referred to eye clinic with decreased vision and photophobia. Visual acuity was reduced to 20/40 in both eyes. Slit-lamp examination revealed bilateral diffuse corneal punctate epitheliopathy and anterior stromal haze. Corneal epitheliopathy seemed like crystal deposits. One day after presentation, mild anterior uveitis was added to clinical picture. All ocular findings disappeared in one week with topical steroid and unpreserved artificial tear drops. We present a case who was diagnosed as incomplete Kawasaki disease along with bilateral diffuse crystalline-like keratopathy. We supposed that unusual ocular presentation may be associated with intravenous immunoglobulin treatment.

    Full Text Available Intravenous immunoglobulins (IVIgs are used for several indications, including autoimmune conditions. IVIg treatment is associated with several possible adverse reactions including induction of a hypercoagulable state. We report a 76-year-old woman treated with IVIg for myasthenia gravis, which developed chest pain and weakness following IVIg infusion. The symptoms were associated with ST segment depression in V4–6 and elevated troponin levels. The patient was diagnosed with non-ST elevation myocardial infarction (NSTEMI. The patient had no significant risk factor besides age and a cardiac perfusion scan was interpreted as normal (the patient refused to undergo cardiac catheterization. This case is compatible with IVIg-induced hypercoagulability resulting in NSTEMI. Cardiac evaluation should therefore be considered prior to initiation of IVIg treatment especially in patients with multiple cardiovascular risks.

    Full Text Available Much attention has been placed recently in transplantation in highly HLA-sensitized patients. In attempts to remove these antibodies and enable successful renal transplantation, several approaches have been developed. Intravenous immunoglobulin (IVIG was found to be effective in the treatment of autoimmune and inflammatory disorders (e. g. Kawasaki disease, Guillain-Barre syndrome. Recently, a beneficial effect of IVIG on the reduc- tion of anti-HLA antibodies was described. The anti-inflammatory effect of IVIG provides hopeful opportunities in antibody-mediated rejection (AMR management. There are several protocols of IVIG administration for pre-transplant desensitization and AMR treatment: high-dose IVIG, low-dose IVIG + plasmapheresis, IVIG + plasmapheresis + rituximab. These advancements have enabled transplantation in patients previously considered untransplantable and in concert with new diagnostic techniques has resulted in new approaches to management of AMR.

    Bullous pemphigoid is an autoantibody-mediated skin blistering disease. Previous studies revealed that intravenous Ig is therapeutic in animal models of bullous pemphigoid by saturating the IgG-protective receptor FcRn, thereby accelerating degradation of pathogenic IgG. Sasaoka et al. demonstrate that the inhibitory effects of intravenous Ig on bullous pemphigoid are also associated with negative modulation of cytokine production by keratinocytes.

    Objective: To compare the therapeutic outcomes of plasmapheresis with intravenous immunoglobulins (IVIG) for Guillain Barre syndrome. Study Design: Randomized controlled trial. Place and Duration of Study: Medicine department; PNS Shifa Hospital Karachi from Jan 2011 to Jun 2012. Patients and Methods: Adult patients admitted to internal medicine department with the diagnosis of Guillain Barre Syndrome (GBS) fulfilling the inclusion and exclusion criteria were included after taking ethical approval and informed consent. They were randomly assigned to plasmapheresis and IVIG treatment groups. Their presenting features, investigations and management plan were followed over 6 months duration. Hughes disability scale for Guillain Barre syndrome was documented and compared at admission, 4 weeks, 12 weeks and 6 months by non-parametric tests via SPSS version 17. Results: Total 36 patients (31 males and 5 females) were included. Mean age was 37 ± 15 (18-70) years, mean duration of symptoms 11.6 ± 12.7 days. Plasmapheresis and IVIG groups were comparable with respect to age and gender (p>0.05). Significant improvement of mean disability score was observed in each group from baseline score (p<0.0005). At specified intervals, comparison between the two groups in terms of mean improvement in disability scores showed significant improvement at 4 weeks (p<0.05) in IVIG group as compared to plasmapheresis group; however on further observation at 12 weeks and 6 months, mean improvement was comparable between two groups with no significant difference (p>0.05). There was no significant difference in need for assisted ventilation between two groups (p>0.05). Variants of GBS observed were AIDP (50%), AMAN (31%) and AMSAN (19%). Conclusion: Our study suggests that both plasmapheresis and intravenous immunoglobulins are useful and effective modes of treatment for Guillain Barre Syndrome. Significant short term improvement was observed in the IVIG group at 4 weeks of treatment; however

    Full Text Available Impetigo herpetiformis (IH, if left untreated, is associated with a high rate of perinatal morbidity and mortality and may lead to the decision of termination of pregnancy. There are various and effective therapeutic agents available for the treatment of the disease. A 23-year-old woman with a history of plaque psoriasis presented with a sudden generalized pustular eruption on the 25th week of her first gestation. The diagnosis was made based on the clinical and histopathological findings. The patient was treated with systemic prednisolone (2 mg/kg/d first and, cyclosporine A (3 mg/kg/d was added to the treatment after two weeks because prednisolone was not effective alone. The lesions did not regress despite four weeks of combined treatment with prednisolone and cyclosporine. Intravenous immunoglobuline (IVIG (0.3 g/kg/d, 6 days was added on the 30th week of gestation and resulted in regression of cutaneous rashes. On the 33rd week of gestation, IVIG (0.7 g/kg/d, 3 days was repeated due to reactivation of pustules, and an improvement was observed. In this case report, we called attention to IVIG therapy in IH, for having the pregnancy continued enough for the fetal maturation before the delivery.

    Full Text Available Background Kawasaki Disease (KD is a vasculitis with multi-organ involvementof unknown etiology; it is the most common cause of pediatric-heart diseases in developed countries. Treatment with Intravenous Immunoglobulin (IVIG prevents coronary artery lesions; although there are some IVIG-resistant cases, combination therapy with corticosteroids and IVIG is one of the recommendations for treatment of these cases. The aim of this study was to compare these three options for treatment of Kawasaki Disease and to evaluate their ability to deal with coronary artery complication of Kawasaki Disease. Materials and Methods A prospective cross- sectional study of hospitalized cases of Kawasaki Disease, conducted in pediatric department of Imam Reza hospital, Mashhad-Iran, during 2013 to 2015 (18 months. Based on demographic and clinical data of these patients, children with high risk of unresponsiveness to IVIG therapy (based on Harada score, were determined and treated with IVIG and corticosteroids- combination initially. Follow-up patients for heart complications were 6 weeks. Results Twenty five patients (89.2% out of total 28 hospitalized patients in this period of time who fulfilled diagnostic criteria were considered as complete Kawasaki Disease. Coronary Artery Lesions (CALs were shown in 4 patients during the follow-up period, with high risk in patients with incomplete presentation (33.3% versus 12%, P

The treatment of RSM remains challenging, and the role of intravenous immunoglobulin (IVIG in RSM is controversial. Case report: Mrs HM, 37 years old, obstetric summary: P0+1+13+1, a known case of hypothyroidism/polycystic ovary syndrome, married to an unrelated 47-year-old man, presented to our RSM clinic in early January 2014 for investigation and treatment. She has had multiple failed in vitro fertilization trials and 13 first-trimester missed miscarriages terminating at 6–7 weeks, all without IVIG therapy. Her tenth pregnancy was spontaneous, managed in London, UK, with multiple supportive therapy and courses of IVIG starting from the third to the 30th week of pregnancy. The pregnancy ended at 36 weeks of gestation with a cesarean section and a live girl baby was delivered. Mrs HM had balanced translocation, 46XX t (7:11 (p10:q10.

    Full Text Available Background: Common variable immunodeficiency is the most commonly-diagnosed primary immunodeficiency in adults; it is characterized by recurrent sinopulmonary and gastrointestinal infections, and increased incidence of malignancy and autoimmune processes. Many patients begin to have clinical manifestations during reproductive age. Case report: A 34-year-old woman with 12 weeks of gestation who was diagnosed with common variable immunodeficiency after recurrent episodes of rhinosinusitis, pharyngoamygdalitis, and pneumonia. 0.6 g/kg of IVIG was prescribed every 21 days during the second trimester; the patient only presented one episode of pharyngoamygdalitis, with adequate response to treatment with antibiotics. During the third trimester the dose was adjusted to every 14 days. The patient ended the pregnancy at term without complications, with a child without defects and with proper weight and size. Conclusions: The administration of immunoglobulin is the main treatment to control common variable immunodeficiency. While the recommended starting dose is 400-800 mg/kg intravenously every 3 to 4 weeks, there is no consensus on the dose to be used in pregnant women. The recommendation is to perform serum level controls before infusion to determine and adjust it.

    The antiphospholipid syndrome (APS) is defined by the occurrence of venous and arterial thromboses and recurrent fetal losses, frequently accompanied by a moderate thrombocytopenia, in the presence of antiphospholipid antibodies (aPL), namely lupus anticoagulant (LA), anticardiolipin antibodies (aCL), or anti-β2 glycoprotein-I (β2GPI) antibodies. The current mainstay of treatment for thrombotic APS is heparin followed by long-term anticoagulation, while in obstetric APS, the accepted first-line treatment consists in low-dose aspirin (LDA) plus prophylactic unfractionated or low-molecular-weight heparin (LMWH). Recently, new emerging treatment modalities, including intravenous immunoglobulins (IVIG), have been implemented to manage APS refractory to conventional therapy. The objective of this review is to summarize the currently available information on the IVIG therapy in APS, focusing on the use of IVIG in the obstetric form, CAPS and on primary or secondary thromboprophylaxis. We analyzed 35 studies, reporting the effects of IVIG in APS patients, and we discussed their results. IVIG in obstetric APS seem to be very useful in selected situations (patients not responsive to the conventional treatment, concomitant autoimmune manifestations or infections or patients in whom anticoagulation is contraindicated). IVIG treatment represents an important component of the combination therapy of CAPS and they could be useful, in addition to the standard therapy, to prevent recurrent thrombosis in APS patients refractory to conventional anticoagulant treatment. Anyway, in some cases we also found controversial results that claim the need of further well-designed studies to definitely state the efficacy and tolerability of IVIG in CAPS, obstetric and non-APS.

    Monoclonal gammopathy-associated systemic capillary-leak syndrome, also known as Clarkson disease, is a rare condition characterized by recurrent life-threatening episodes of capillary hyperpermeability in the context of a monoclonal gammopathy. This study was conducted to better describe the clinical characteristics, natural history, and long-term outcome of monoclonal gammopathy-associated systemic capillary-leak syndrome. We conducted a cohort analysis of all patients included in the European Clarkson disease (EurêClark) registry between January 1997 and March 2016. From diagnosis to last follow-up, studied outcomes (eg, the frequency and severity of attacks, death, and evolution toward multiple myeloma) and the type of preventive treatments administered were monitored every 6 months. Sixty-nine patients (M/F sex ratio 1:1; mean ± SD age at disease onset 52 ± 12 years) were included in the study. All patients had monoclonal gammopathy of immunoglobulin G type, with kappa light chains in 47 (68%). Median (interquartile range) follow-up duration was 5.1 (2.5-9.7) years. Twenty-four patients (35%) died after 3.3 (0.9-8) years. Fifty-seven (86%) patients received at least one preventive treatment, including intravenous immunoglobulins (IVIg) n = 48 (73.8%), theophylline n = 22 (33.8%), terbutaline n = 22 (33.8%), and thalidomide n = 5 (7.7%). In the 65 patients with follow-up, 5- and 10-year survival rates were 78% (n = 35) and 69% (n = 17), respectively. Multivariate analysis found preventive treatment with IVIg (hazard ratio 0.27; 95% confidence interval, 0.10-0.70; P = .007) and terbutaline (hazard ratio 0.35; 95% confidence interval, 0.13-0.96; P = .041) to be independent predictors of mortality. We describe the largest cohort to date of patients with well-defined monoclonal gammopathy-associated systemic capillary-leak syndrome. Preventive treatment with IVIg was the strongest factor associated with survival, suggesting the use of IVIg as the first

    Full Text Available  Background: Drug use evaluation (DUE aims at improving the patients’ care. Studying the administration pattern of intravenous immunoglobulin (IVIG is an important research topic due to its significant role in the treatment and controlling of many disorders, high prices, and limited availability of this drug.  Methods:This observational cross-sectional study was conducted at Shahid Sadoughi Hospital in Yazd, central Iran, from May to September 2014. The orders of different wards in the hospital for IVIG given to the hospital central pharmacy were surveyed. Also, a special form developed for evaluation the method of administration. The related physician and nurse were consulted on drug complications and the causes. Finally, the gleaned data were compared to the available standards on the prescription and administration of IVIG.Results:A total of 75 patients received IVIG during this study. 58.7% of the prescriptions belonged to the cases approved by Food and Drug Administration (FDA. The most frequent cause of the use of IVIG was idiopathic thrombocytopenic purpura (ITP. The rate and dose of administration was suitable in most of the patients, yet, the measurement of laboratory parameters required for IVIG were observed in only a few cases. Complications occurred in 26.7% of the patients receiving it, which was mostly related to infusion-related reactions. On the whole, 3922 g IVIG was used during this study of which 1848 g belonged to the cases approved by FDA.Conclusion:Regarding the high costs of IVIG, complications, and limited information on the quality of the effect of this drug in the treatment of many cases, physicians should be cautious enough with its appropriate use. Besides, the presence of a clinical pharmacist in the health-care team not only improves the quality of drug therapy and treatment results, but also plays an important part in decreasing the treatment costs for the patients.

    Immunoadsorption (IA) is increasingly used instead of plasma exchange due to lower risk of side effects and a higher selectivity. As a consequence of the reduction of immunoglobulins (Ig), the rate of infectious complications might increase in those patients. We therefore aimed to investigate the infection rate following IA without intravenous IG (IVIG) substitution in our apheresis center, where patients do not receive IVIG on a regular basis. We conducted a retrospective analysis of the IA treatments performed between 2010 and 2015 without IVIG substitution and collected data on patient age, diagnosis, number of IA treatments, serum levels of Ig, total protein, albumin, C-reactive protein (CRP) and infectious complications that occurred within 2 months after the IA treatment cycle. A total number of 52 patients (27 females) received at least 5 IA sessions using the following adsorbers: TheraSorb™-Ig (n = 3), TheraSorb™-Ig flex (n = 44), TheraSorb™ Ig pro (n = 1) and TheraSorb™-IgE (n = 5). The median number of treatment sessions was 8.8 [range 5-16], the median IgG reduction was 82 [11-99] %. Serum albumin was decreased by 8%. The median CRP levels remained normal until the end of therapy and within 2 months after that (3.10 and 4.30 mg/L respectively). Only 4 patients had infections (7.7%). Three of them received additional immunosuppressive therapy. Immunoadsorption leads to a significant reduction of IgG. CRP as inflammatory marker is not affected. Even without substitution of IVIG the complication rate directly linked with IA is low and questionable. Copyright © 2017 Elsevier B.V. All rights reserved.

    Although pulse-dose dexamethasone is increasingly favored for treating pediatric opsoclonus-myoclonus syndrome (OMS), and multimodal immunotherapy is associated with improved clinical response, there have been no neuroimmunologic studies of dexamethasone-based multimodal disease-modifying therapy. In this observational retrospective study, 19 children with OMS (with or without associated neuroblastoma) underwent multibiomarker evaluation for neuroinflammation. Nine children of varying OMS severity, duration, and treatment status were treated empirically with pulse dexamethasone, intravenous immunoglobulin (IVIg), and rituximab combination immunotherapy (DEXIR-CI). Another 10 children on dexamethasone alone or with IVIg at initial evaluation only provided a comparison group. Motor severity (total score) was scored rater-blinded via videotapes using the validated OMS Evaluation Scale. DEXIR-CI was associated with a 69% reduction in group total score (P = 0.004) and was clinically well tolerated. Patients given the dexamethasone combination exhibited significantly lowered B cell frequencies in cerebrospinal fluid (-94%) and blood (-76%), normalizing the cerebrospinal fluid B cell percentage. The number of patients with positive inflammatory markers dropped 87% (P = 0.002) as did the number of markers. Cerebrospinal fluid oligoclonal bands were positive in four of nine pretreatment patients but zero of six post-treatment patients. In the comparison group, partial response to dexamethasone alone or with IVIg was associated with multiple positive markers for neuroinflammation despite an average of seven months of treatment. Multimechanistic dexamethasone-based combination immunotherapy increases the therapeutic armamentarium for OMS, providing a viable option for less severely affected individuals. Partial response to dexamethasone with or without IVIg is indicative of ongoing neuroinflammation and should be treated promptly and accordingly. Copyright © 2017

    Intravenous immunoglobulin (IVIg) is a polyclonal immunoglobulin G preparation with potent immunomodulatory properties. The mode of action of IVIg has been investigated in multiple disease states, with various mechanisms described to account for its benefits. Recent data indicate that IVIg increases both the number and the suppressive capacity of regulatory T cells, a subpopulation of T cells that are essential for immune homeostasis. IVIg alters dendritic cell function, cytokine and chemokine networks, and T lymphocytes, leading to development of regulatory T cells. The ability of IVIg to influence Treg induction has been shown both in animal models and in human diseases. In this review, we discuss data on the potential mechanisms contributing to the interaction between IVIg and the regulatory T-cell compartment.

    Common variable immunodeficiency (CVID) is a heterogeneous subset of immunodeficiency disorders. Recurrent bacterial infection is the main feature of CVID, but various non-infectious complications can occur. A 42-year-old woman presented with cough and abnormal chest X-ray shadows. Laboratory tests showed remarkable hypogammaglobulinemia. Computed tomography revealed multiple consolidation and nodules on the bilateral lung fields, systemic lymphadenopathy, and splenomegaly. A surgical lung biopsy specimen provided the final diagnosis of lymphoproliferative disease in CVID, which was grouped under the term granulomatous lymphocytic interstitial lung disease. Interestingly, the lung lesions of this case resolved immediately after the initiation of intravenous immunoglobulin monotherapy.

    Cardiopulmonary manifestations of adult-onset Still's disease (AOSD) include pericarditis, pleural effusion, transient pulmonary infiltrates, pulmonary interstitial disease and myocarditis. Serositis are common but pneumonitis and myocarditis are not and bring elevated risk of mortality. They may manifest on disease onset or flares. Previously reported cases were treated with high-dose glucocorticoids and immunosupressants and, when refractory, intravenous immunoglobulin (IVIG). We report an AOSD patient whose flare presented with severe pleupneumonitis and myopericarditis and, following nonresponse to a methylprednisolone pulse, high dose of prednisone and cyclosporine A, recovered after a 2-day 1g/kg/day IVIG infusion.

    Full Text Available Background: Common variable immunode ciency (CVID is the most frequent symptomatic primary immunodeficiency, affecting 1:25,000- 75,000 people. It is characterized by the absence or decrease antibody production. Treatment for CVID consists on human immunoglobulin administration, and the intravenous route is the most common route for administration, at 400-800 mg/kg of weight every 3-4 weeks. Adverse effects associated with intravenous immunoglobulin (IVIg use occur in 25% of all infusions, with severe adverse reactions presenting in less than 1% of all patients. Acute renal failure can occur as a severe adverse reaction, which presents 1-10 days after starting IVIg treatment. In our center we implemented an ambulatory scheme for IVIg administration, which allows its administration in an average of 3 hours, without severe adverse effects. Objectives: To describe adverse effects and to evaluate the frequency of renal failure secondary to ambulatory IVIg administration in patients with common variable immunode ciency. Material and method: A descriptive and prospective study was done including adult patients con de nitive diagnosis of common variable immunodeficiency, receiving IVIg at replacement dose every 3 weeks. All patients were evaluated with clinical exploration, somatometry, serum creatinine, albumin and urea determination, 24 hours creatinine clearance, glomerular ltration rate with CKD-EPI, and immediate renal function associated with accumulated IVIg. Results were analyzed with descriptive statistics. Results: We determined adverse effects in 25 patients with common variable immunode ciency (15 women and 10 men, average age 36.7 years, during a 10 months period (January-September 2013. During this period 284 IVIg infusions were administered using our scheme, frequency of adverse effects were 12.9%, with 5.2% of early adverse effects and 7.7% late adverse effects, all being mild to moderate, in some cases required analgesic and

    Refractory recurrent pericarditis is a major clinical challenge after colchicine failure, especially in corticosteroid-dependent patients. Human intravenous immunoglobulins (IVIGs) have been proposed as possible therapeutic options for these cases. The goal of this systematic review is to assess the efficacy and safety of IVIGs in this context. Studies reporting the use of IVIG for the treatment of recurrent pericarditis and published up to October 2014 were searched in several databases. All references found, upon initial assessment at title and abstract level for suitability, were consequently retrieved as full reports for further appraisal. Among the 18 citations retrieved, 17 reports (4 case series and 13 single case reports, with an overall population of 30 patients) were included. The mean disease duration was 14 months and the mean number of recurrences before IVIG was 3. Approximately 47% of patients had idiopathic recurrent pericarditis, 10% had an infective cause, and the remainder a systemic inflammatory disease. Nineteen out of the 30 patients (63.3%) were on corticosteroids at IVIG commencement. IVIGs were generally administered at a dose of 400-500 mg/kg/day for 5 consecutive days with repeated cycles according to the clinical response. Complications were uncommon (headache in ~3%) and not life-threatening. After a mean follow-up of approximately 33th months, recurrences occurred in 26.6% of cases after the first IVIG cycle, and 22 of the 30 patients (73.3%) were recurrence-free. Five patients (16.6%) were on corticosteroids at the end of the follow-up. IVIGs are rapidly acting, well tolerated, and efficacious steroid-sparing agents in refractory pericarditis.

    Hemolytic disease of newborn (HDN) is a condition that develops in a fetus, when the IgG molecules produced by the mother pass through the placenta and attack the fetal red blood cells. HDN can occur due to Rh and ABO incompatibilities between the mother and the fetus as well as due to other allo-immune antibodies belonging to Kell (K and k), Duffy (Fya), Kidd (Jka and Jkb), and MNS (M, N, S, and s) systems. Role of intravenous immunoglobulin in management of HDN is not clear.SARA red blood cell antigen, first discovered in 1990 is a low frequency antigen. We report, a multiparous female whose pregnancy was complicated by HDN due to anti-SARA antibodies requiring both exchange transfusion and intravenous immunoglobulin. The response was sustained after intravenous immunoglobulin (IVIG) rather than after exchange transfusion.

  1. Endothelial Cell Amplification of Regulatory T Cells Is Differentially Modified by Immunosuppressors and Intravenous Immunoglobulin

    Full Text Available Immunosuppressive treatment is a prerequisite for both organ transplantation and tolerance of the allograft. However, long-term immunosuppression has been associated with a higher incidence of malignancies and infections. Immunosuppressors mainly target circulating immune cells and little is known of their “off-target” effects, such as their impact on endothelial cells (ECs. In chronic antibody-mediated rejection (AMR, the allograft endothelium is a target of damage, histologically detected as transplant glomerulopathy, and which correlates with poor graft survival. Under inflammatory conditions, EC expression of HLA class II antigens can lead to CD4+-T lymphocyte alloactivation and selective expansion of pro-inflammatory Th17 and pro-tolerance Treg subsets. This response can be modified and preactivation of the EC by HLA-DR antibody binding promoted a proinflammatory Th17 response. However, whether or not immunosuppressors alter EC immunogenicity has not been examined. In alloimmunized patients with AMR, cyclosporine A (CsA and mycophenolic acid (MPA are often combined with intravenous immunoglobulins (IVIgs. This study reports changes in the microvascular EC phenotype and function after treatment with CsA, MPA, or IVIg. Both CsA and MPA decreased HLA-DR and increased CD54 expression, whereas IVIg increased HLA-DR expression. Interleukin 6 secretion was reduced by all three immunomodulators. Preincubation of ECs with CsA or MPA limited, while IVIg amplified, Treg expansion. Because CsA, MPA, and IVIg are known for their ability to act upon leukocytes, we confirmed that ECs maintained their immunoregulatory role when allogeneic leukocytes were pretreated with CsA, MPA, or IVIg. The results reveal that individual immunosuppressors, used in the induction and maintenance of renal allograft tolerance, had direct and distinct effects on ECs. Results of experiments associating IVIg with either CsA or MPA underlined the differences observed using

    2015-01-01

    Full Text Available A 57-year-old male presented with a 6-month history of blisters and painful erosions on the right buccal mucosa. No skin or other mucosal involvement was seen. The findings of histopathological and direct immunofluorescence examinations were sufficient for the diagnosis of oral mucous membrane pemphigoid in the context of adequate clinical correlation. No response was seen after topical therapies and oral corticosteroids or dapsone. Intravenous immunoglobulin was started and repeated every three weeks. Complete remission was achieved after three cycles and no recurrence was seen after two years of follow-up. The authors report a rare unilateral presentation of oral mucous membrane pemphigoid on the right buccal and hard palate mucosa, without additional involvement during a period of five years. Local trauma or autoimmune factors are possible etiologic factors for this rare disorder, here with unique presentation.

    We report a screen of plasma donors confirming that widespread use of childhood measles vaccination since 1963 resulted in a decrease in average measles virus antibody titers among plasma donors, which is reflected in intravenous immunoglobulins (IVIGs). The measles virus antibody titer, however, is a potency requirement for IVIGs, as defined in a Food and Drug Administration regulation. To mitigate the decline in measles virus antibody titers in IVIGs and to ensure consistent product release, revaccination of plasma donors was investigated as a means to boost titers. However, revaccination-induced titer increases were only about 2-fold and short-lived. © The Author 2017. Published by Oxford University Press for the Infectious Diseases Society of America.

    The use of intravenous immunoglobulin (IVIg) has been reported as an immunomodulating agent in several autoimmune diseases, including systemic lupus erythematosus (SLE). Herein we report a SLE patient with severe clinical presentation that included pericarditis, pleural effusion, nephrotic range proteinuria, leukopenia, and lymphopenia. The patient received one course of high-dose IVIg (2.8 g/kg body weight), and within a week of post-IVIg therapy, her condition significantly improved. One-month post-IVIg there were decreased proteinuria, elevated leukocytes and lymphocytes count, decrease in antinuclear and anti-dsDNA antibodies, and disappearance of pericarditis and pleuritis. This case demonstrates the efficacy of IVIg in severe SLE with various clinical manifestations.

    Full Text Available The efficacy of intravenous immunoglobulins (IVIg in patients with autoimmune diseases (AID has been known for several decades. Majority of these patients received IVIg in hospital. A retrospective study was conducted in 22 centers in France to evaluate the feasibility of the administration of Tegeline, an IVIg from LFB Biomedicaments, and assess its safety at home, compared to in hospital, in patients with AID. The included patients were at least 18 years old, suffering from AID, and treated with at least 1 cycle of Tegeline at home after receiving 3 consecutive cycles of hospital-based treatment with Tegeline at a dose between 1 and 2 g/kg/cycle. Forty-six patients with AID, in most cases immune-mediated neuropathies, received a total of 138 cycles of Tegeline in hospital and then 323 at home. Forty-five drug-related adverse events occurred in 17 patients who received their cycles at home compared to 24 adverse events in hospital in 15 patients. Serious adverse events occurred in 3 patients during home treatment, but they were not life-threatening and did not lead to discontinuation of Tegeline. Forty-five patients continued their treatment with Tegeline at home or in hospital; 39 (84.8% were still receiving home treatment at the end of the study. In conclusion, the study demonstrates the good safety profile of Tegeline administered at home at high doses in patients with AID who are eligible for home administration of Tegeline.

    Patients with antibody deficiencies depend on the presence of a variety of antibody specificities in intravenous immunoglobulin (IVIG) to ensure continued protection against pathogens. Few studies have examined levels of antibodies to specific pathogens in IVIG preparations and little is known about the specific antibody levels in patients under regular IVIG treatment. The current study determined the range of antibodies to tetanus, diphtheria, measles and varicella in IVIG products and the levels of these antibodies in patients undergoing IVIG treatment. We selected 21 patients with primary antibody deficiencies who were receiving regular therapy with IVIG. Over a period of one year, we collected four blood samples from each patient (every 3 months), immediately before immunoglobulin infusion. We also collected samples from the IVIG preparation the patients received the month prior to blood collection. Antibody levels to tetanus, diphtheria, measles and varicella virus were measured in plasma and IVIG samples. Total IgG levels were determined in plasma samples. Antibody levels to tetanus, diphtheria, varicella virus and measles showed considerable variation in different IVIG lots, but they were similar when compared between commercial preparations. All patients presented with protective levels of antibodies specific for tetanus, measles and varicella. Some patients had suboptimal diphtheria antibody levels. There was a significant correlation between serum and IVIG antibodies to all pathogens, except tetanus. There was a significant correlation between diphtheria and varicella antibodies with total IgG levels, but there was no significant correlation with antibodies to tetanus or measles. The study confirmed the variation in specific antibody levels between batches of the same brand of IVIG. Apart from the most common infections to which these patients are susceptible, health care providers must be aware of other vaccine preventable diseases, which still exist

    Outcome of patients with transplant glomerulopathy (TG) is poor. Using B-cell targeting molecules represent a rational strategy to treat TG during chronic antibody-mediated rejection. In this pilot study, 21 patients with this diagnosis received four doses of intravenous immunoglobulins and two doses of rituximab (IVIG/RTX group). They were retrospectively compared with a untreated control group of 10 patients. At 24 months post-biopsy, graft survival was similar and poor between the treated and the untreated group, 47% vs. 40%, respectively, p = 0.69. This absence of response of IVIG/RTX treatment was observed, regardless the phenotype of TG. Baseline estimated glomerular filtration rate (eGFR) and decline in eGFR during the first six months after the treatment were risk factors associated with 24-month graft survival. The IVIG/RTX therapy had a modest effect on the kinetics of donor-specific alloantibodies at M24, compared to the untreated group, not associated with an improvement in graft survival. The mean number of adverse events per patient was higher in the IVIG/RTX group than in the control group (p = 0.03). Taken together, IVIG/RTX treatment for severe TG during chronic antibody-mediated rejection does not seem to change the natural history of TG and is associated with a high incidence of adverse events. © 2015 John Wiley & Sons A/S.

    Intravenous immunoglobulin (IVIG) is an important research topic because of its efficacy in the management of an increasing number of diseases, its high cost and limited availability. This study was designed to evaluate the paediatric inpatient use of IVIG and identify strategies to reduce the drug expenditures. Over a six-month period, physician and nursing charts, and notes for subjects who were treated with IVIG, were reviewed to gather the required data. This included patient demographics, IVIG, indications, dosage regimen, adverse drug reactions (ADRs) and their management. 58.3 percent of IVIG infusions were ordered for labelled indications. Patients in the labelled group experienced more clinical improvement than subjects in the off-label group. Haematologists and neurologists were the most prevalent prescribers. ADRs were more prevalent in the off-label group. Hypotension, fever, headache and chills were the most common adverse effects. ADRs were managed with drugs in 22.9 percent of IVIG administrations and IVIG infusions were modified in 12.5 percent of infusions. ADRs were more prevalent in this hospital than those reported by other authors. This may be due to nursing negligence of the recommended infusion rate, higher sensitivity of our population or to the brands of IVIG which are used in the hospital. This shows the need for further evaluation of IVIG prescription and administration.

    Full Text Available Immunoglobulin G (IgG of excellent quality for intravenous use was obtained from the cryosupernatant of human plasma by a chromatographic method based on a mixture of ion-exchange, DEAE-Sepharose FF and arginine Sepharose 4B affinity chromatography and a final purification step by Sephacryl S-300 HR gel filtration. The yield of 10 experimental batches produced was 3.5 g IgG per liter of plasma. A solvent/detergent combination of 1% Tri (n-butyl phosphate and 1% Triton X-100 was used to inactivate lipid-coated viruses. Analysis of the final product (5% liquid IgG based on the mean for 10 batches showed 94% monomers, 5.5% dimers and 0.5% polymers and aggregates. Anticomplementary activity was 0.3 CH50/mg IgG and prekallikrein activator levels were less than 5 IU/ml. Stability at 37ºC for 30 days in the liquid state was satisfactory. IgG was stored in flasks (2.5 g/flask at 4 to 8ºC. All the characteristics of the product were consistent with the requirements of the 1997 Pharmacopée Européenne.

    A new human liquid intravenous immunoglobulin product, Flebogamma DIF, has been developed. This IgG is purified from human plasma by cold ethanol fractionation, PEG precipitation and ion exchange chromatography. The manufacturing process includes three different specific pathogen clearance (inactivation/removal) steps: pasteurization, solvent/detergent treatment and Planova nanofiltration with a pore size of 20 nm. This study evaluates the pathogen clearance capacity of seven steps in the production process for a wide range of viruses through spiking experiments: the three specific steps mentioned above and also four more production steps. Infectivity of samples was measured using a Tissue Culture Infectious Dose assay (log(10) TCID(50)) or Plaque Forming Units assay (log(10) PFU). Validation studies demonstrated that each specific step cleared more than 4 log(10) for all viruses assayed. An overall viral clearance between > or =13.33 log(10) and > or =25.21 log(10), was achieved depending on the virus and the number of steps studied for each virus. It can be concluded that Flebogamma DIF has a very high viral safety profile. 2010 The International Association for Biologicals. Published by Elsevier Ltd. All rights reserved.

    It has been proposed that the anti-inflammatory effects of intravenous immunoglobulin (IVIG) might be due to the small fraction of Fc-sialylated IgG. In this study we biochemically and functionally characterized sialic acid-enriched IgG obtained by Sambucus nigra agglutinin (SNA) lectin fractionation. Two main IgG fractions isolated by elution with lactose (E1) or acidified lactose (E2) were analyzed for total IgG, F(ab')(2) and Fc-specific sialic acid content, their pattern of specific antibodies and anti-inflammatory potential in a human in vitro inflammation system based on LPS- or PHA-stimulated whole blood. HPLC and LC-MS testing revealed an increase of sialylated IgG in E1 and more substantially in the E2 fraction. Significantly, the increased amount of sialic acid residues was primarily found in the Fab region whereas only a minor increase was observed in the Fc region. This indicates preferential binding of the Fab sialic acid to SNA. ELISA analyses of a representative range of pathogen and auto-antigens indicated a skewed antibody pattern of the sialylated IVIG fractions. Finally, the E2 fraction exerted a more profound anti-inflammatory effect compared to E1 or IVIG, evidenced by reduced CD54 expression on monocytes and reduced secretion of MCP-1 (CCL2); again these effects were Fab- but not Fc-dependent. Our results show that SNA fractionation of IVIG yields a minor fraction (approx. 10%) of highly sialylated IgG, wherein the sialic acid is mainly found in the Fab region. The tested anti-inflammatory activity was associated with Fab not Fc sialylation.

    The worldwide seroprevalence of hepatitis A virus (HAV) and hepatitis B virus (HBV) has changed over the last two decades, indicating a declining incidence of HAV and HBV infections. Therefore, vaccinations against HAV and HBV are recommended for unimmunized people before traveling to an endemic area. Unfortunately, primary antibody deficiency (PAD) patients can only obtain humoral immunity through intravenous immunoglobulin G (IVIG) replacement and not from vaccination because of a defect in antibody production. However, few studies have analyzed the titers of antibodies against HAV or HBV in IVIG products. In this study, the titers of anti-HAV and anti-HBs antibodies were measured in nineteen lots of IVIG products from five manufacturers from three countries (A, B from Korea; C, D from Japan; and E from the USA), and trough titers in plasma were estimated. Concentrations of anti-HAV antibody ranged from 1,888-8,927 mIU/mL and estimated trough titers exceeded the minimal protective value in all evaluated IVIG products. Concentrations of anti-HBs antibody ranged from 438-965 mIU/mL in products A and B and were 157, 123, and 1,945 mIU/mL in products C, D, and E, respectively. Estimated trough titers in products A, B, and E exceeded the minimal protective value but those in products C and D did not reach this threshold. These data demonstrated that available IVIG products generally provide sufficient antibodies against HAV and HBV to protect patients with PAD, although the trough concentrations of anti-HBs antibody in two IVIG products did not reach the minimum protective value.

    Although intravenous immunoglobulin G (IVIG) therapy has been reported in hyperbilirubinemia of Rh hemolytic disease, its use in ABO hemolytic disease has been reported in only a few studies. In our institute we have observed that almost 30% of babies with hyperbilirubinemia due to ABO hemolytic disease required exchange transfusion. To determine whether administration of IVIG to newborns with significant hyperbilirubinemia due to ABO hemolytic disease would reduce the need for exchange transfusion as a primary goal in these babies. This was a prospective study involving all newborns with significant hyperbilirubinemia due to direct Coombs-positive ABO hemolytic disease. All healthy term babies with ABO hemolytic disease with positive direct Coombs test in the period between 2000 and 2002 were identified. Significant hyperbilirubinemia was defined as hyperbilirubinemia requiring phototherapy and/or rising by 8.5 micromol/l per h (0.5 mg/dl per h) or more to require exchange transfusion. Babies were randomly assigned into two groups: group 1 (study group) received phototherapy plus IVIG (500 mg/kg); and group 2 (control group) received phototherapy alone. Exchange transfusion was carried out in any group if at any time the bilirubin level reached 340 micromol/l (20 mg/dl) or more, or rose by 8.5 micromol/l per h (0.5 mg/dl per h) in group 2. A total of 112 babies were enrolled over 2 years, 56 in each group. Exchange transfusion was carried out in four babies in the study group, while 16 babies in the control group required exchange. Late anemia was not of concern in either group. No adverse effects related to IVIG administration were recorded. Administration of IVIG to newborns with significant hyperbilirubinemia due to ABO hemolytic disease with positive direct Coomb's test reduces the need for exchange transfusion without producing immediate adverse effects.

    Full Text Available Japanese encephalitis (JE virus (JEV is a mosquito-borne flavivirus found across Asia that is closely related to West Nile virus. There is no known antiviral treatment for any flavivirus. Results from in vitro studies and animal models suggest intravenous immunoglobulin (IVIG containing virus-specific neutralizing antibody may be effective in improving outcome in viral encephalitis. IVIG's anti-inflammatory properties may also be beneficial.We performed a pilot feasibility randomized double-blind placebo-controlled trial of IVIG containing anti-JEV neutralizing antibody (ImmunoRel, 400mg/kg/day for 5 days in children with suspected JE at two sites in Nepal; we also examined the effect on serum neutralizing antibody titre and cytokine profiles. 22 children were recruited, 13 of whom had confirmed JE; 11 received IVIG and 11 placebo, with no protocol violations. One child (IVIG group died during treatment and two (placebo subsequently following hospital discharge. Overall, there was no difference in outcome between treatment groups at discharge or follow up. Passive transfer of anti-JEV antibody was seen in JEV negative children. JEV positive children treated with IVIG had JEV-specific neutralizing antibody titres approximately 16 times higher than those treated with placebo (p=0.2, which was more than could be explained by passive transfer alone. IL-4 and IL-6 were higher in the IVIG group.A trial of IVIG for JE in Nepal is feasible. IVIG may augment the development of neutralizing antibodies in JEV positive patients. IVIG appears an appealing option for JE treatment that warrants further study.ClinicalTrials.gov NCT01856205.

    In patients with primary antibody deficiencies, subcutaneous administration of IgG (SCIG) replacement is effective, safe, well-tolerated, and can be self-administered at home. A new SCIG replacement at 20% concentration (Hizentra ® ) has been developed and has replaced Vivaglobin ® (SCIG 16%). An observational prospective multi-centric open-label study, with retrospective comparison was conducted in 15 Italian centers, in order to investigate whether and to what extent switching to Hizentra ® would affect frequency of infusions, number of infusion sites, patients' satisfaction, and tolerability in patients previously treated with Vivaglobin ® or intravenous immunoglobulins (IVIG). Any variations of dosage, frequency and duration of the infusions, and of number of infusion sites induced by Hizentra ® with respect to the former treatment were recorded. Practical advantages and disadvantages of Hizentra ® , with respect to the medicinal product formerly used, and the variations in patients' therapy-related satisfaction were monitored by means of the TSQM (Treatment Satisfaction Questionnaire for Medication); number, frequency, and duration of infectious events and adverse effects were recorded. Eighty-two patients switched to Hizentra ® : 19 (23.2%) from IVIG and 63 (76.8%) from Vivaglobin ® . The mean interval between infusions was not affected by the shift (7.0 ± 2.0 days with previous treatment versus 7.1 ± 1.2 during Hizentra ® ). A decrease in the number of infusion sites with Hizentra ® was recorded in 12 out of 56 patients for whom these data were available. At 6 months, 89.7% of patients were satisfied with Hizentra ® ; no difference in terms of effectiveness, side effects, convenience, and global satisfaction was observed. No difference in the incidence of adverse events was reported.

  18. Intravenous immunoglobulin prevents murine antibody-mediated acute lung injury at the level of neutrophil reactive oxygen species (ROS production.

    John W Semple

    Full Text Available Transfusion-related acute lung injury (TRALI is a leading cause of transfusion-associated mortality that can occur with any type of transfusion and is thought to be primarily due to donor antibodies activating pulmonary neutrophils in recipients. Recently, a large prospective case controlled clinical study of cardiac surgery patients demonstrated that despite implementation of male donors, a high incidence of TRALI still occurred and suggested a need for additional interventions in susceptible patient populations. To examine if intravenous immunoglobulin (IVIg may be effective, a murine model of antibody-mediated acute lung injury that approximates human TRALI was examined. When BALB/c mice were injected with the anti-major histocompatibility complex class I antibody 34-1-2s, mild shock (reduced rectal temperature and respiratory distress (dyspnea were observed and pre-treatment of the mice with 2 g/kg IVIg completely prevented these symptoms. To determine IVIg's usefulness to affect severe lung damage, SCID mice, previously shown to be hypersensitive to 34-1-2s were used. SCID mice treated with 34-1-2s underwent severe shock, lung damage (increased wet/dry ratios and 40% mortality within 2 hours. Treatment with 2 g/kg IVIg 18 hours before 34-1-2s administration completely protected the mice from all adverse events. Treatment with IVIg after symptoms began also reduced lung damage and mortality. While the prophylactic IVIg administration did not affect 34-1-2s-induced pulmonary neutrophil accumulation, bone marrow-derived neutrophils from the IVIg-treated mice displayed no spontaneous ROS production nor could they be stimulated in vitro with fMLP or 34-1-2s. These results suggest that IVIg prevents murine antibody-mediated acute lung injury at the level of neutrophil ROS production and thus, alleviating tissue damage.

    Full Text Available Abstract Intravenous immunoglobulin (IVIg is a blood-derived product, used for the treatment of immunodeficiency and autoimmune diseases. Since a range of immunotherapies have recently been proposed as a therapeutic strategy for Parkinson’s disease (PD, we investigated the effects of an IVIg treatment in a neurotoxin-induced animal model of PD. Mice received four injections of MPTP (15 mg/kg at 2-hour intervals followed by a 14-day IVIg treatment, which induced key immune-related changes such as increased regulatory T-cell population and decreased CD4+/CD8+ ratio. The MPTP treatment induced significant 80% and 84% decreases of striatal dopamine concentrations (P P P

She received five pulses of IVMP (30 mg/kg/day. Two weeks after steroid weaning, she developed right hemiplegia and coma. Brain magnetic resonance imaging showed a left frontal necrotico-hemorrhagic lesion and new multifocal areas of demyelination. She underwent decompressive craniotomy and evacuation of an ongoing left frontoparietal hemorrhage. Comprehensive investigations ruled out vascular and infectious process. The neurological deterioration stopped concomitantly with combined neurosurgical drainage of the hematoma, decompressive craniotomy, IVMP, and intravenous immunoglobulins (IVIG. She developed during the following months Crohn disease and sclerosing cholangitis. After 2-year follow-up, there was no new neurological manifestation. The patient still suffered right hemiplegia and aphasia, but was able to walk. Cognitive/behavioral abilities significantly recovered. A heterozygous novel rare missense variant (c.4993A>G, p.Lys1665Glu was identified in RANBP2, a gene associated with acute necrotizing encephalopathy. RANBP2 is a protein playing an important role in the energy homeostasis of neuronal cells.ConclusionIn any ADS occurring in the context of SCD and/or autoimmune condition, we recommend to slowly wean steroids and to closely monitor the patient after weaning to quickly treat any recurrence of neurological symptom

    Full Text Available Dengue represents an important health problem in Brazil and therefore there is a great need to develop a vaccine or treatment. The neutralization of the dengue virus by a specific antibody can potentially be applied to therapy. The present paper describes, for the first time, the preparation of Immunoglobulin specific for the dengue virus (anti-DENV IgG, collected from screened Brazilian blood-donations. Production was performed using the classic Cohn-Oncley process with minor modifications. The anti-DENV IgG was biochemically and biophysically characterized and fulfilled the requirements defined by the European Pharmacopoeia. The finished product was able to neutralize different virus serotypes (DENV-1, DENV-2, and DENV-3, while a commercial IgG collected from American blood donations was found to have low anti-dengue antibody titers. Overall, this anti-DENV IgG represents an important step in the study of the therapeutic potential and safety of a specific antibody that neutralizes the dengue virus in humans.

    Cationization of proteins in general enhances the cellular uptake of these macromolecules, and cationized antibodies are known to retain antigen binding properties. Therefore, cationized antibodies may be therapeutic and allow for intracellular immunization. The present studies test the hypothesis that the tissue uptake of cationized immunoglobulin G (IgG) after intravenous administration may be greatly increased relative to the uptake of native proteins. The pharmacokinetics of cationized immunoglobulin G clearance from blood, and the volume of distribution of the cationized or native protein (albumin, IgG) for 10 organs was measured both in anesthetized rats and in an anesthetized adult Macaca irus cynomologous monkey. Initial studies on brain showed that serum factors inhibited uptake of 125I-cationized IgG, but not 3H-cationized IgG. The blood-brain barrier permeability surface area product for 3H-cationized IgG was 0.57 ± 0.04 microliters min-1 g-1. The ratio of the volume of distribution of the 3-H-cationized IgG compared to 3H-labeled native albumin ranged from 0.9 (testis) to 15.7 (spleen) in the rat at 3 hr after injection, and a similarly enhanced organ uptake was observed in the primate. In conclusion, these studies demonstrate that cationization of immunoglobulin greatly increases organ uptake of the plasma protein compared to native immunoglobulins, and suggest that cationization of monoclonal antibodies may represent a potential new strategy for enhancing the intracellular delivery of these proteins

    Full Text Available Viral safety of human plasma products plays a key role in their safe uses. Solvent- detergent (SD virus-inactivation method has gained widespread popularity in the manufacture of biological products. This treatment which inactivates lipid-enveloped viruses effectively consists of incubation of a plasma protein solution in the presence of a non-volatile organic solvent and a detergent. In this study, IgM-enriched immunoglobulin was incubated at 24 °C for 6 h under slow stirring in the presence of tri(n-butyl phosphate (0.3% w/w as solvent and tween 80 (1% w/w as detergent. After completion of the inactivation process and removal of the solvent-detergent, the ability of SD-treatment to remove Infectious Bovine Rhinotracheitis (IBR virus (a lipid-enveloped virus and Foot-and-Mouth Disease virus (a non-enveloped virus were evaluated by "virus spiking studies" using a scaled down process. Reduction factor of 4 log was obtained for the SD-treatment of IgM-enriched immunoglobulin spiked with IBR virus. No virus inactivation was observed in the SD-treated IgM-enriched immunoglobulin, spiked with Foot-and-Mouth Disease virus. It was concluded that treatment of IgM-enriched immunoglobulin with TNBP-TWEEN 80 may be considered as an efficient lipid-enveloped virus inactivation step in the manufacture of this product.

    Full Text Available In connective tissue diseases, autoantibodies cause pulmonary interstitial inflammation and fibrosis, and patients require treatment with an immunosuppressive agent such as a steroid. Dermatomyositis is an incurable, uncommon form of connective tissue disease that occasionally causes diffuse pulmonary inflammation leading to acute severe respiratory failure. In such cases, the prognosis is very poor despite treatment with high-dose steroid. In the present case, a 46-year-old man was admitted to our hospital with dyspnea. He was diagnosed with dermatomyositis combined with cryptogenic organizing pneumonia (COP with respiratory failure and underwent treatment with steroid and an immunosuppressive agent, but the COP was not improved. However, the respiratory failure did improve after treatment with intravenous immunoglobulin, which therefore can be considered a treatment option in cases where steroids and immunosuppressive agents are ineffective.

    IVIG consumption is increasing due to the fact that in many cases the drugs are being used off-label. IVIG were more likely to be used in autoimmune and systemic inflammatory diseases. However, in randomized clinical trials, a good effect was achieved only in Kawasaki disease and immune thrombocytopenic purpura. Current clinical guidelines narrowed the indications for IVIG, limiting their use in sepsis. Immunoglobulin replacement therapy is recommended for children with physiological delay of immunoglobulin production only in repeated infections, which can not be controlled or prevented with antibiotics. In secondary ID, replacement therapy must be carried out if the cause of hypogammaglobulinemia can not be eliminated or elimination is contraindicated, as well as in association with β-cell cancers, in which severe infections caused by encapsulated bacteria persist despite preventive antibiotic therapy.

    Preexisting donor-specific antibodies against human leukocyte antigens are major risk factors for acute antibody-mediated and chronic rejection of kidney transplant grafts. Immunomodulation (desensitization) protocols may reduce antibody concentration and improve the success of transplant. We investigated the effect of desensitization with intravenous immunoglobulin and rituximab on the antibody profile in highly sensitized kidney transplant candidates. In 31 transplant candidates (calculated panel-reactive antibody [cPRA], 34%-99%), desensitization included intravenous immunoglobulin on days 0 and 30 and a single dose of rituximab on day 15. Anti-human leukocyte antigen antibodies were analyzed before and after desensitization. Reduction of cPRA from 25% to 50% was noted for anti-class I (5 patients, within 20-60 days) and anti-class II (3 patients, within 10-20 days) antibodies. After initial reduction of cPRA, the cPRA increased within 120 days. In 24 patients, decrease in mean fluorescence intensity of antibodies by more than 50% was noted at follow-up, but there was no reduction of cPRA. Rebound occurred in 65% patients for anti-class I antibodies at 350 days and anti-class II antibodies at 101 to 200 days. Probability of rebound effect was higher in patients with mean fluorescence intensity of more than 10,700 before desensitization, anti-class II antibodies, and history of previous transplant. The desensitization protocol had limited efficacy in highly sensitized kidney transplant candidate because of the short period with antibody reduction and high frequency of rebound effect.

    To investigate the clinical effect and safety of anti-D immunoglobulin (anti-D) in the treatment of children with newly diagnosed acute immune thrombocytopenia (ITP) through a Meta analysis. PubMed, EMBASE, Cohrane Library, Ovid, CNKI, and Wanfang Data were searched for randomized controlled trials (RCTs) published up to April 2017. Review Manager 5.3 was used for the Meta analysis. Seven RCTs were included. The Meta analysis showed that after 72 hours and 7 days of treatment, the intravenous immunoglobulin (IVIG) group had a significantly higher percentage of children who achieved platelet count >20×10 9 /L than the anti-D group (Panti-D (50 μg/kg) group and the IVIG group (P>0.05), and there were also no significant differences in platelet count after 24 hours and 7 days of treatment between the 50 μg/kg and 75 μg/kg anti-D groups (P>0.05). The anti-D group had a significantly greater reduction in the hemoglobin level than the IVIG group after treatment, but did not need transfusion. No children in the anti-D group or the IVIG group experienced serious adverse reactions. Intravenous injection of anti-D may have a similar effect as IVIG in improving platelet count in children with acute ITP, but it may be slightly inferior to IVIG in the rate of platelet increase after treatment. The anti-D dose of 50 μg/kg may have a similar effect as 75 μg/kg. The recommended dose of anti-D for treatment of ITP is safe.

We studied 24 patients diagnosed as having relapsing and remitting MS, of whom 12 received intravenous immunoglobulin G; a control group of 12 were given placebo. In a double-blind study, MRI was obtained initially and at 3, 6 and 9 months, and interpreted without knowledge of clinical findings, laboratory tests or treatment. The lesions were classified according to their distribution and evaluated qualitatively and quantitatively. Each patient was also examined clinically and scored according to the expanded disability status scale (EDSS) following every MRI examination. All patients in the treatment group showed significant improvement. The lesions decreased in both in size and number in all sites. In the control group lesions increased both in number and size in all sites, but only the increase between 3and 6 months was statistically significant. In both groups, significant apparent changes were detected in the cerebellum and brain stem. Volumetric evaluation was found to be more helpful than qualitative assessment. (orig.)

    Eosinophilic granulomatosis with polyangiitis (EGPA), previously called Churg-Strauss syndrome, frequently affects the peripheral nervous system. We conducted a multicenter, double-blind, three-arm treatment period, randomized, pre-post trial to assess the efficacy of intravenous immunoglobulin (IVIg) administration for residual peripheral neuropathy in patients with EGPA that is in remission, indicated by laboratory indices. Twenty-three patients were randomly assigned into three groups, in which the timing of IVIg and placebo administration was different. Each group received one course of intervention and two courses of placebo at 2-week intervals. Treatment effects were assessed every 2 weeks for 8 weeks. The primary outcome measure, the amount of change in the manual muscle testing sum score 2 weeks after IVIg administration, significantly increased (p = 0.002). The results over time suggested that this effect continued until the last assessment was done 8 weeks later. The number of muscles with manual muscle testing scores of three or less (p = 0.004) and the neuropathic pain scores represented by the visual analogue scale (p = 0.005) also improved significantly 2 weeks after IVIg administration. This study indicates that IVIg treatment for EGPA patients with residual peripheral neuropathy should be considered even when laboratory indices suggest remission of the disease.

    Coagulation factors (II, VII, IX, X, and particularly XIa) remaining in high concentrations in intravenous immunoglobulin (IVIG) preparations can form thrombi, causing thromboembolic events, and in serious cases, result in death. Therefore, manufacturers of biological products must investigate the ability of their production processes to remove procoagulant activities. Previously, we were able to remove coagulation factors II, VII, IX, and X from our IVIG preparation through ethanol precipitation, but factor XIa, which plays an important role in thrombosis, remained in the intermediate products. Here, we used a chromatographic process using a new resin that binds with high capacity to IgG and removes procoagulant activities. The procoagulant activities were reduced to low levels as determined by the thrombin generation assay: 250 s, FXI/FXIa ELISA: <0.31 ng/mL. Even after spiking with FXIa at a concentration 32.5 times higher than the concentration in normal specimens, the procoagulant activities were below the detection limit (<0.31 ng/mL). These results demonstrate the ability of our manufacturing process to remove procoagulant activities to below the detection limit (except by NaPTT), suggesting a reduced risk of thromboembolic events that maybe potentially caused by our IVIG preparation.

    This study assessed the validity of using established Japanese risk scoring methods to predict intravenous immunoglobulin (IVIG) resistance to Kawasaki disease in Israeli children. We reviewed the medical records of 282 patients (70% male) with Kawasaki disease from six Israeli medical centres between 2004-2013. Their mean age was 2.5 years. The risk scores were calculated using the Kobayashi, Sano and Egami scoring methods and analysed to determine if a higher risk score predicted IVIG resistance in this population. Factors that predicted a lack of response to the initial IVIG dose were identified. We found that 18% did not respond to the first IVIG dose. The three scoring methods were unable to reliably predict IVIG resistance, with sensitivities of 23-32% and specificities of 67-87%. Calculating a predictive score that was specific for this population was also unsuccessful. The factors that predicted a lacked of response to the first IVIG dose included low albumin, elevated total bilirubin and ethnicity. The established risk scoring methods created for Japanese populations with Kawasaki disease were not suitable for predicting IVIG resistance in Caucasian Israeli children and we were unable to create a specific scoring method that was able to do this.

    Full Text Available Intravenous immunoglobulin (IVIG is commonly used for a wide range of diagnoses, by multiple pediatric subspecialists. We report two cases of hepatitis B screening results post IVIG infusion, where positive anti-Hepatitis B core antigen serology tests indicated possible occult hepatitis infection, leading to a delay in care. However, serial antibody testing showed results consistent with the passive transfer of antibodies.

    Variations in muscle strength and function have not been studied in patients with chronic inflammatory demyelinating polyneuropathy and multifocal motor neuropathy whose treatment regimen has been changed from intravenous to subcutaneous immunoglobulin (IVIg to SCIg). In a prospective, open-label study, patients were changed from monthly IVIg to weekly SCIg. The primary endpoint was variation in isokinetic muscle strength (cIKS). Secondary endpoints were variations in Medical Research Council (MRC) score, grip strength (GS), 9-hole-peg test (9-HPT), and 40-meter-walk test (40-MWT). The coefficient of variance of cIKS during the IVIg and SCIg treatment periods was unchanged (mean ± SD: 6.97 ± 4.83% vs. 5.50 ± 3.13%, P = 0.21). The variations in the 9-HPT and 40-MWT were significantly lower in the SCIg group (P = 0.01 and P = 0.005, respectively). When therapy was changed from IVIg to SCIg, fluctuation of muscle strength was unchanged, but performance fluctuations were diminished. Muscle Nerve 57: 610-614, 2018. © 2017 Wiley Periodicals, Inc.

    Full Text Available Posttransplant antiglomerular basement membrane (anti-GBM disease occurs in approximately 5% of Alport patients and usually ends in irreversible graft failure. Recent research has focused on characterizing the structure of the anti-GBM alloepitope. Here we present a case of a 22-year-old male with end-stage renal disease secondary to Alport syndrome, with a previously failed renal allograft, who received a second deceased-donor kidney transplant. Six days after transplantation, he developed acute kidney injury. The serum anti-GBM IgG was negative by enzyme immunoassay (EIA. On biopsy, he had crescentic glomerulonephritis with linear GBM fixation of IgG. With further analysis by western blotting, we were able to detect antibodies to an unidentified protein from the basement membrane. This patient was treated with plasmapheresis twice per week and monthly intravenous immunoglobulin (IVIG for a total of five months. At the end of treatment, these unknown antibodies were no longer detected. His renal function improved, and he has not required dialysis. We conclude that anti-GBM disease in patients with Alport Syndrome may be caused by circulating antibodies to other components of the basement membrane that are undetectable by routine anti-GBM EIA and may respond to treatment with plasmapheresis and IVIG.

    Human intravenous immunoglobulin (IGIV) has been in use for the past 20 years. This biological product is commonly provided in liquid or lyophilized dosage form. When the lyophilized product is rehydrated, it is usually administered within 2-3 h from time of complete dissolution. While this practice is advisable whenever possible, occasionally the patient or care-giver may need to delay the infusion. Hence, a study of the stability of lyophilized IGIV after reconstitution with water for injection was conducted. The reconstituted product was stored either in its original glass container or pooled into poly(vinyl chloride) (PVC) bags. The effect of extended storage on the active ingredient (IgG), excipients (glucose, albumin) and extractables [sodium from glass vials, and di-(2-ethyl-hexyl) phthalate and cyclohexanone from PVC bags] was evaluated. The stability of the active ingredient was evaluated by physico-chemical tests (molecularsize distribution, pH, appearance, total protein), monitoring titres of a specific antibody (hepatitis B surface antigen) and an antibody functional test (bacterial opsonization). To evaluate the risk of microbial contamination during reconstitution and pooling procedures, sterility, pyrogen and animal-safety tests were included in the protocol. The potential of IgG polymerizing in solution during storage and subsequent complement activation was evaluated by assaying for non-specific binding of complement (anti-complement activity). Results show that aseptically reconstituted IGIV is stable and remains sterile up to 48 h at 5 degrees C. The reconstituted product was also found to be stable at room temperature (25 degrees C) up to 12 h.

    Full Text Available Guillain-Barré syndrome (GBS is an acute symmetrical pa- ralyzing disease due to a demyelinating polyrradiculoneuropathy, often induced by a preceding infection 1. The main modalities for the treatment of GBS include plasmapheresis and intrave- nous immune globulin. Reports of the use of IVIG in children with GBS are limited: 1 g/kg for two days or 400 mg/kg for five days. While these studies in children are not definitive because of design limitations, their results are consistent with the larger randomized trials in adults 2,3.

    Women with elevated natural killer (NK) cell frequency and function during pregnancy, suffer from recurrent pregnancy loss (RPL). In the present study, the possible effect of intravenous immunoglobulin (IVIG) administration on Th1 and Th2 cell frequency, cytokine secretion, and expression of transcription factors is compared between RPL patients and control group. Totally, 44 women with a history of RPL (32 women as treated group and 12 as control group) were enrolled in the study. The frequency of Th1 and Th2 lymphocytes, the expression of transcription factors related to these cells and the serum levels of associated cytokines were assessed by flowcytometry, real-time PCR and ELISA, respectively. All, assessments were performed both before and after treatment with IVIG. A significant reduction in Th1 lymphocyte frequency, transcription factor expression and cytokine levels were observed in IVIG-treated group, while all the above parameters indicated a significant increase for Th2 lymphocytes. Th1/Th2 ratio decreased significantly (p value<0.0001) at the end of treatment and 28 out of 32 (87.5%) women in IVIG-treated group had live birth in comparison with 5 out of 12 (41.6%) in untreated group. IVIG administration proves to be an efficient therapeutic strategy which is able to enhance the success rate of pregnancy through a shift in Th2 responses. Furthermore, IVIG presents efficacy for the treatment of reproduction failures especially in subjects with immune cell abnormalities and increased NK cell level and function.

    Pregnant women with triple antibody positive antiphospholipid syndrome (APS) who have had thrombosis or a history of early, severe pregnancy complications are generally considered at high risk of pregnancy loss. The objectives of this study were to investigate the efficacy and safety of a relatively new treatment protocol used in addition to conventional therapy in high-risk pregnant patients affected with primary APS. The study's two inclusion criteria were: (1) the presence of triple antiphospholipid positivity, (2) previous thrombosis and/or a history of one or more early, severe pregnancy complications. Eighteen pregnancies occurring between 2002 and 2015 in 14 APS patients, (mean age 34.8±3.6 SD) were monitored. All 14 (100%) patients had triple antiphospholipid positivity. In addition, six of them (42.8%) had a history of thrombosis, four (28.6%) had one or more previous early and severe pregnancy complications, and four (30.8%) met both clinical study criteria. The study protocol included weekly plasmapheresis or immunoadsorption and fortnightly 1g/kg intravenous immunoglobulins. Seventeen of the pregnancies (94.4%) produced live neonates, all born between the 26th and 37th weeks of gestation (mean 33.1±3.5 SD). One female (5.5%), born prematurely at 24 weeks, died of sepsis a week after birth. There were two cases (11.1%) of severe pregnancy complications. No treatment side effects were registered. Given the high live birth rate and the safety associated to it, the study protocol described here could be taken into consideration by medical teams treating high-risk APS pregnant patients.

    Chemotherapy remains a mainstay of treatment for cancer patients. However, anti-cancer drugs frequently cause a wide range of side effects, including leukopenia and gastrointestinal toxicity. These adverse effects can lead to treatment delays or necessitate temporary dose reductions. Although chemotherapy-related changes in gut morphology have been demonstrated, the influences of chemotherapeutic regimens on gut immunity are understood poorly. This study aimed to examine whether the anti-cancer drug paclitaxel (PTX) impairs gut immunity in mice. Male ICR mice were randomized into three groups: Control, low-dose PTX (low PTX; 2 mg/kg), or high-dose PTX (high PTX; 4 mg/kg). A single intravenous dose was given. On day seven after the injection, lymphocytes from Peyer patches (PP), intraepithelial (IE) spaces, and the lamina propria (LP) were counted and analyzed by flow cytometry (CD4(+), CD8(+), αβTCR(+), γδTCR(+), B220(+)). Immunoglobulin A (IgA) concentrations were measured in small intestinal and respiratory tract washings. Total, CD4(+) and γδTCR(+) lymphocyte numbers in PPs were significantly lower in the high PTX than in the control group. The CD4(+) lymphocyte numbers in the IE spaces were significantly lower in both PTX groups than in the control group. Respiratory tract IgA concentrations were lower in the high PTX than in the control group. The present data suggest high-dose PTX impairs mucosal immunity, possibly rendering patients more vulnerable to infection. Careful dose selection and new therapies may be important for maintaining mucosal immunity during PTX chemotherapy.

    A 7-year-old Japanese boy with a 4-month history of systemic juvenile idiopathic arthritis (s-JIA) experienced disease flare with spiking fever, exanthema and arthralgia. He then developed progressive dyspnea due to severe pericarditis, and proinflammatory hypercytokinemia was suspected. Methylprednisolone pulse therapy was ineffective and echocardiography showed massive pericardial effusion had persisted. Alternatively, subsequent intravenous immunoglobulin (IVIG) therapy resulted in dramatic resolution of the pericardial effusion, and his general condition significantly improved within a few days. This case report may lend further support the use of IVIG for selected patients with s-JIA and severe pericarditis.

    Pregnancies at risk of fetal and neonatal alloimmune thrombocytopenia (FNAIT) are commonly treated using weekly intravenous immunoglobulin (IVIG) at 1 g/kg maternal weight. IVIG is an expensive multidonor human blood product with dose-related side effects. Our aim was to evaluate the effectiveness of IVIG at a lower dose, i.e., 0.5 g/kg. This was a randomized controlled multicenter trial conducted in Sweden, the Netherlands and Australia. Pregnant women with human platelet antigen alloantibodies and an affected previous child without intracranial hemorrhage (ICH) were enrolled. The participants were randomized to IVIG at 0.5 or 1 g/kg per week. The analyses were per intention to treat. The primary outcome was fetal or neonatal ICH. Secondary outcomes were platelet count at birth, maternal and neonatal IgG levels, neonatal treatment and bleeding other than ICH. A total of 23 women were randomized into two groups (low dose: n = 12; standard dose: n = 11). The trial was stopped early due to poor recruitment. No ICH occurred. The median newborn platelet count was 81 × 10(9)/l (range 8-269) in the 0.5 g/kg group versus 110 × 10(9)/l (range 11-279) in the 1 g/kg group (p = 0.644). The risk of adverse outcomes in FNAIT pregnancies treated with IVIG at 0.5 g/kg is very low, similar to that using 1 g/kg, although our uncompleted trial lacked the power to conclusively prove the noninferiority of using the low dose.

    Prior clinical trials have suggested that home-based Ig treatment in multifocal motor neuropathy (MMN) and chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) and its variant Lewis-Sumner syndrome (LSS) is safe and effective and is less costly than hospital-administered intravenous immunoglobulin (IVIg). A French prospective, dual-center, cost minimization analysis was carried out to evaluate IVIg administration (5% concentrated) at home versus in hospital with regard to costs, patients' autonomy, and patients' quality of life. The primary endpoint was the overall cost of treatment, and we adopted the perspective of the payer (French Social Health Insurance). Twenty-four patients aged 52.3 (12.2) years were analyzed: nine patients with MMN, eight with CIDP, and seven with LSS. IVIg (g/kg) dosage was 1.51 ± 0.43 in hospital and 1.52 ± 0.4 at home. Nine-month total costs per patient extrapolated to 1 year of treatment were €48,189 ± 26,105 versus €91,798 ± 51,125 in the home and hospital groups, respectively ( p  home treatment were the good tolerance and absence of side effects of IVIg administration, as well as a good understanding of the advantages and drawbacks of home treatment (75% of respondents). The mRankin scores before and after switch to home treatment were 1.61 ± 0.72 and 1.36 ± 0.76, respectively ( p  =   .027). The switch from hospital-based to home-based IVIg treatment for patients with immune neuropathy represents potentially significant savings in the management of the disease.

    Primary antibody deficiencies require lifelong replacement therapy with immunoglobulin (Ig)G to reduce the incidence and severity of infections. Both subcutaneous and intravenous routes of administering IgG can be effective and well tolerated. Treatment regimens can be individualized to provide optimal medical and quality-of-life outcomes in infants, children, adults and elderly people. Frequency, dose, route of administration, home or infusion-centre administration, and the use of self- or health-professional-administered infusion can be tailored to suit individual patient needs and circumstances. Patient education is needed to understand the disease and the importance of continuous therapy. Both the subcutaneous and intravenous routes have advantages and disadvantages, which should be considered in selecting each patient's treatment regimen. The subcutaneous route is attractive to many patients because of a reduced incidence of systemic adverse events, flexibility in scheduling and its comparative ease of administration, at home or in a clinic. Self-infusion regimens, however, require independence and self-reliance, good compliance on the part of the patient/parent and the confidence of the physician and the nurse. Intravenous administration in a clinic setting may be more appropriate in patients with reduced manual dexterity, reluctance to self-administer or a lack of self-reliance, and intravenous administration at home for those with good venous access who prefer less frequent treatments. Both therapy approaches have been demonstrated to provide protection from infections and improve health-related quality of life. Data supporting current options in IgG replacement are presented, and considerations in choosing between the two routes of therapy are discussed. © 2014 British Society for Immunology.

    The Di(b) antigen usually occurs with high incidence, except in certain Asian and South American Indian populations. In general, hemolysis caused by anti-Di(b) is not severe and its clinical course is benign. We report a Korean neonate with severe hemolytic disease of the newborn caused by anti-Di(b). The phenotype and genotype of the Diego blood group system of the patient and his mother were Di(a+b+) and Di(a+b-), respectively. The mother's serum and eluate from the neonate's erythrocytes contained anti-Di(b). This case was successfully managed with phototherapy and high dose iv immunoglobulin. Since most commercial antibody detection panels do not contain Di(b-) red cells, it is important to consider anti-Di(b) in cases of hemolytic disease of the newborn caused by an antibody against a high frequency antigen.

    Full Text Available Abstract Introduction We report the case of a patient with Churg-Strauss syndrome with eighth cranial nerve palsy. Vestibulocochlear nerve palsy is extremely rare in Churg-Strauss syndrome. To the best of our knowledge, only one case of complicated neuropathy of the eighth cranial nerve has been described in a previous report presenting an aggregate calculation, but no differentiation between polyarteritis nodosa and Churg-Strauss syndrome was made. High-dose immunoglobulin was administered to our patient, and her neuropathy of the eighth cranial nerve showed improvement. Case presentation At the age of 46, a Japanese woman developed Churg-Strauss syndrome that later became stable with low-dose prednisolone treatment. At the age of 52, she developed sudden difficulty of hearing in her left ear, persistent severe rotary vertigo, and mononeuritis multiplex. At admission, bilateral perceptive deafness of about 80dB and eosinophilia of 4123/μL in peripheral blood were found. A diagnosis of cranial neuropathy of the eighth cranial nerve associated with exacerbated Churg-Strauss syndrome was made. Although high doses of steroid therapy alleviated the inflammatory symptoms and markers, the vertigo and bilateral hearing loss remained. Addition of a high-dose immunoglobulin finally resulted in marked alleviation of the symptoms associated with neuropathy of the eighth cranial nerve. Conclusions A high dose of immunoglobulin therapy shows favorable effects in neuropathy of the eighth cranial nerve, but no reports regarding its efficacy in cranial neuropathy have been published.

    Intravenous immunoglobulin (IVIG) is a polyspecific pooled immunoglobulin G preparation and one of the commonly used therapeutics for autoimmune diseases including those of neurological origin. A recent report in murine model proposed that IVIG expands regulatory T (T reg ) cells via induction of interleukin 33 (IL-33). However, translational insight on these observations is lacking. Ten newly diagnosed Guillain-Barré syndrome (GBS) patients were treated with IVIG at the rate of 0.4 g/kg for three to five consecutive days. Clinical evaluation for muscular weakness was performed by Medical Research Council (MRC) and modified Rankin scoring (MRS) system. Heparinized blood samples were collected before and 1, 2, and 4-5 weeks post-IVIG therapy. Peripheral blood mononuclear cells were stained for surface CD4 and intracellular Foxp3, IFN-γ, and tumor necrosis factor alpha (TNF-α) and were analyzed by flow cytometry. IL-33 and prostaglandin E2 in the plasma were measured by ELISA. The fold changes in plasma IL-33 at week 1 showed no correlation with the MRC and MRS scores at weeks 1, 2, and ≥4 post-IVIG therapy. Clinical recovery following IVIG therapy appears to be associated with T reg cell response. Contrary to murine study, there was no association between the fold changes in IL-33 at week 1 and T reg cell frequency at weeks 1, 2, and ≥4 post-IVIG therapy. T reg cell-mediated clinical response to IVIG therapy in GBS patients was associated with reciprocal regulation of effector T cells-expressing TNF-α. T reg cell expansion by IVIG in patients with autoimmune diseases lack correlation with IL-33. T reg cell frequency, but not plasma IL-33 levels, represents potential immunological biomarker to predict clinical response to IVIG therapy.

We sought to evaluate the pharmacokinetic characteristics of anti-HBIG quantitatively during the first 6 months after liver transplantation. Methods: Identical doses of 10,000 IU HBIG were administered to adult liver transplant recipients daily during the first week, weekly thereafter until 28 postoperative days, and monthly thereafter. Blood samples were obtained at days 1, 7, 28, 84, and 168 after transplantation. Plasma HBIG titer was quantified using 4 different immunoassay methods. The titer determined by each analytical method was used for mixed-effect modeling, and the most precise results were chosen. Simulations were performed to predict the plausible immunoglobulin maintenance dose. Results: HBIG was eliminated from the body most rapidly in the immediate post-transplant period, and the elimination rate gradually decreased thereafter. In the early post-transplant period, patients with higher DNA titer tend to have lower plasma HBIG concentrations. The maintenance doses required to attain targets in 90%, 95%, and 99% of patients were ~15.3, 18.2, and 25.1 IU, respectively, multiplied by the target trough level (in IU/L. Conclusion: The variability (explained and unexplained in HBIG pharmacokinetics was relatively larger in the early post-transplant period. Dose individualization based upon

    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.

    Phosphodiesterase inhibitors such as milrinone can relieve symptoms and improve hemodynamics in patients with advanced congestive heart failure. We retrospectively evaluated the hemodynamic and clinical outcomes of long-term combination therapy with intravenous milrinone and oral β-blockers in 65 patients with severe congestive heart failure (New York Heart Association class IV function and ejection fraction milrinone. Oral medical therapy was maximized when possible. The mean duration of milrinone treatment in this combination-treatment group was 269 days (range, 14–1,026 days). Functional class improved from IV to II–III with milrinone therapy. Twenty-four such patients tolerated β-blocker up-titration and were successfully weaned from milrinone. Sixteen patients (31%) died while receiving combination therapy; one died of sudden cardiac death (on treatment day 116); the other 15 died of progressive heart failure or other complications. Hospital admissions during the previous 6 months and admissions within 6 months after milrinone initiation stayed the same. Meanwhile, the total number of hospital days decreased from 450 to 380 (a 15.6% reduction), and the mean length of stay decreased by 1.4 days (a 14.7% reduction). We conclude that 1) milrinone plus β-blocker combination therapy is an effective treatment for heart failure even with β-blocker up-titration, 2) weaning from milrinone may be possible once medications are maximized, 3) patients' functional status improves on the combination regimen, and 4) treatment-related sudden death is relatively infrequent during the combination regimen.

Assim, estes resultados sugerem que a IGEV diminui o tempo necessário para a melhora clínica quando comparado com tratamento suportivo.We report our experience with intravenous immunoglobulin (IVIG, plasmapheresis and supportive care in 13 patients with the Guillain-Barré syndrome. Seven of 13 patients received IVIG, 2 plasmapheresis and 4 supportive care. At 15th day after IVIG administration, all patients in this group had improved at least one disability grade. In the plasmapheresis group, 1 improved at 5th day after the procedure. Two of the 4 patients that received supportive care improved at 20th day of evaluation. In the IVIG group, the final scores were lower and had no relapses. These results suggest faster clinical improvement with IVIG when compared with supportive measures.

    Parvovirus B19 (B19) disease is a rare cause of anemia in cancer patients and often goes unrecognized, causing delays in anticancer therapy. A retrospective review was carried out of the records of patients with multiple myeloma who underwent melphalan-based autologous stem cell transplantation (MEL-ASCT) and developed B19 infection (January 2009-December 2011). Cases were defined by the presence of clinical and laboratory findings consistent with B19 disease in patients with repeatedly positive plasma quantitative polymerase chain reaction for parvovirus. Six patients qualified as cases; 5 presented with trilineage cytopenias (chronic in 1) and 1 with anemia later progressing to pancytopenia. Transfusion-dependent thrombocytopenia led to testing in 5 patients. Two of these patients also had manifestations of autoimmune disease. Therapy with intravenous immunoglobulin (IVIG) resulted in clinical and hematologic response in all; however, 1 patient, whose white blood cell counts and serum hemoglobin levels improved, required splenectomy for persistent thrombocytopenia. All patients required additional IVIG for recurrent B19 disease. Although viral load at diagnosis did not correlate with the severity of cytopenia, its decrease was associated with response during 17 of 20 evaluable episodes (P = 0.02). Preemptive IVIG allowed the safe administration of chemotherapy in 3 patients, including MEL-ASCT in 1. Parvovirus B19 can cause severe disease in myeloma patients including ASCT recipients. Thrombocytopenia - not anemia - was the leading presentation and may be associated with autoimmune conditions. Patients with unexplained cytopenias, particularly when prolonged, should undergo testing for circulating parvovirus. A reduction in viral load was associated with response to IVIG, although additional therapy was needed for recurrent disease. Most importantly, preemptive IVIG allowed for safe and timely administration of antineoplastic therapy in patients with ongoing B

    Peristomal pyoderma gangrenosum (PPG) is a rare subtype of pyoderma gangrenosum that is characterized by painful, necrotic ulcerations occurring in the area surrounding an abdominal stoma. PPG is typically seen in younger patients with active inflammatory bowel disease. The etiology and pathogenesis is largely unknown and risk factors are not well defined. Therapy typically involves a combination of aggressive local wound care and systemic medications. Diagnosis and management of PPG can be difficult and data on treatment are limited. We present a case of severe postoperative peristomal recalcitrant to conventional therapy successfully treated with intravenous immune globulin. PMID:25802252

    Objective: To assess the beneficial effect of intravenous pamidronate treatment in children with osteogenesis imperfecta (OI). Study Design: Experimental study. Place and Duration of Study: Endocrine Unit at the National Institute of Child Health, Karachi, Pakistan, from January 2007 to December 2011. Methodology: All children diagnosed with osteogenesis imperfecta on the basis of repeated spontaneous fractures and typical radiological findings registered during the study period, were included in this study. Pamidronate therapy were offered to those with more than 3 fractures per year or had platyspondyly. Pamidronate disodium was diluted in isotonic saline and administered by slow ravenous infusion over 3 hours in a dosage 1 mg/kg/day for 3 consecutive days 3 monthly for 2 years. Fracture rate, bone mineral density (BMD), mobility score, wellbeing and pain episodes were evaluated at baseline and 2 years after the treatment. Good response was defined as less than 2 fractures per year or mobility score improvement and poor response as more than 2 fracture per year with mobility score less than 2. Results: Seventy two patients were included in this study. There were 40 boys and 32 girls with mean age of 3.64 +- 3.2 years. The annual fracture rate decreased overall from 5.8 +- 1.61 to 0.6 +- 0.93 (p < 0.001). BMD Z-score improved from -5.3 +- 1.74 to -1.7 +- 0.72 (p < 0.001). Mobility score was 0.94 +- 1.30 at baseline and 2.5 +- 1.02 at the end of the treatment (p < 0.001). Wellbeing gained from 3.63 +- 1.44 to 7.8 +- 1.18 (p < 0.001) and pain episode improved from 24.1 +- 8.15 to 2.7 +- 8.31 (p < 0.001). Good response was noted in 92% of patients and poor response in 8% patients. Conclusion: Bisphosphonate seems to be an effective symptomatic treatment for children with osteogenesis imperfecta irrespective of severity of mutation or clinical phenotype. Cyclical bisphosphonate therapy has a positive effect on fracture rate, BMD, mobility score, wellbeing and pain

    Intravenous phenobarbital (IV-PB) therapy was launched in Japan in October 2008. We retrospectively investigated its efficacy and tolerability in patients with status epilepticus. Forty-three consecutive patients received IV-PB for status epilepticus between June 2009 and April 2011. Among them, 39 patients had underlying diseases, which included acute diseases in 19 patients and chronic conditions in 20 patients. Although 18 patients had been taking antiepileptic drugs (AEDs) before the occurrence of status epilepticus, the blood AED concentrations in 8 patients was below the therapeutic levels. Before the administration of IV-PB, 39 patients were treated with intravenous benzodiazepine, 17 patients were treated with intravenous phenytoin, and 15 patients with intravenous infusion of lidocaine. The initial doses of IV-PB ranged from 125 to 1,250 mg (1.9-20.0 mg/kg). Additional doses of IV-PB were required in 12 patients. Seizures were controlled in 35 patients (81%) after IV-PB administration. Cessation of status epilepticus was attained in 24 patients after the initial dose and in 11 patients after additional doses. There were no serious adverse effects, although respiratory suppression was observed in 3 patients and drug eruption was observed in 1 patient. IV-PB is relatively safe and effective for controlling status epilepticus. If the first dose is not effective, additional doses are required up to the recommended maximum dose.

    The aim of this trial was to investigate the efficacy of massive i.v. immunoglobulin (MIVIg) treatment for women with a history of recurrent spontaneous abortion (RSA) due to unexplained aetiology. The study included nine women (11 pregnancies) with a history of four or more consecutive RSA with unexplained aetiology and no live births. The mean number of fetal losses was 4.5 (range 4-6 abortions). Over the course of 5 days, immunoglobulin (20 g/day) was infused i.v. at gestational weeks 4-7. No additional infusions were carried out. Two pregnancies out of the 11 conceptions resulted in missed abortions at gestational weeks 6 and 7 respectively. Mosaicism (46XX/ 48XX, +16, +20), and tetraploidy (92XXXX) were found by chromosome analyses of the two aborti. Eight out of the other nine pregnancies resulted in full term deliveries of healthy neonates. One pregnancy developed intrauterine growth retardation and fetal distress, resulting in a premature delivery (30 gestational weeks) by Caesarean section. Thus, excluding the two abortions with chromosome aberrations, the MIVIg treatment was effective in all nine pregnancies of RSA women with unexplained aetiology. This MIVIg treatment (100 g administered in early gestation) may be a beneficial alternative to previous IVIg infusion methods, and should be further evaluated in a multicentric, placebo-controlled study, employing a larger number of homogeneous patients who fall into a high risk category of first trimester abortions.

    Intravenous levetiracetam (LEV) has been shown to be effective and safe in treating adults with refractory status epilepticus (SE). We sought to investigate the efficacy and safety of intravenous LEV for pediatric patients with refractory SE. We performed a retrospective medical-record review of pediatric patients who were treated with intravenous LEV for refractory SE. Clinical information regarding age, sex, seizure type, and underlying neurological status was collected. We evaluated other anticonvulsants that were used prior to administration of intravenous LEV and assessed loading dose, response to treatment, and any adverse events from intravenous LEV administration. Fourteen patients (8 boys and 6 girls) received intravenous LEV for the treatment of refractory SE. The mean age of the patients was 4.4 ± 5.5 years (range, 4 days to 14.6 years). Ten of the patients were neurologically healthy prior to the refractory SE, and the other 4 had been previously diagnosed with epilepsy. The mean loading dose of intravenous LEV was 26 ± 4.6 mg/kg (range, 20-30 mg/kg). Seizure termination occurred in 6 (43%) of the 14 patients. In particular, 4 (57%) of the 7 patients younger than 2 years showed seizure termination. No immediate adverse events occurred during or after infusions. The current study demonstrated that the adjunctive use of intravenous LEV was effective and well tolerated in pediatric patients with refractory SE, even in patients younger than 2 years. Intravenous LEV should be considered as an effective and safe treatment option for refractory SE in pediatric patients.

    Incarcerated intravenous heroin users have more problematic patterns of heroin use, but are less likely to access methadone maintenance treatment by their own initiative than heroin users in the community. The present study examined predictors for receiving methadone maintenance treatment post-release among incarcerated intravenous heroin users within a 24-month period. This cohort study recruited 315 incarcerated intravenous heroin users detained in 4 prisons in southern Taiwan and followed up within the 24-month period post-release. Cox proportional hazards regression analysis was applied to determine the predictive effects of sociodemographic and drug-use characteristics, attitude toward methadone maintenance treatment, human immunodeficiency virus serostatus, perceived family support, and depression for access to methadone maintenance treatment after release. There were 295 (93.7%) incarcerated intravenous heroin users released that entered the follow-up phase of the study. During the 24-month follow-up period, 50.8% of them received methadone maintenance treatment. After controlling for the effects of the detainment period before and after recruitment by Cox proportional hazards regression analysis, incarcerated intravenous heroin users who had positive human immunodeficiency virus serostatus (HR = 2.85, 95% CI = 1.80-4.52, p maintenance treatment before committal (HR = 1.94, 95% CI = 1.23-3.05, p maintenance treatment within the 24-month follow-up period. Positive human immunodeficiency virus serostatus with fully subsidized treatment and previous methadone maintenance treatment experiences predicted access of methadone maintenance treatment post-release. Strategies for getting familiar with methadone maintenance treatment during detainment, including providing methadone maintenance treatment prior to release and lowering the economic burden of receiving treatment, may facilitate entry of methadone maintenance treatment for incarcerated intravenous heroin

    We studied effects of OK-432 on the bone marrow and peripheral blood cells of lung cancer patients. The nuclear cell count of bone marrow increased in 5 to 7 patients upon intravenous treatment with OK-432 compared with 3 of 6 patients who were intramuscularly treated with OK-432. Serial neutrophil counts of bone marrow increased in all 7 patients treated intravenously compared with 3 of 6 patients treated intramuscularly. The mean nuclear cell count or the serial neutrophil count of bone marrow in intravenously treated patients was significantly higher than the pretreatment values (p less than 0.001). In the peripheral blood picture, the difference in white blood cells or neutrophils before and after intravenous treatment was also statistically significant (p less than 0.01). There was no change in the erythrocytic series count of bone marrow and the hemoglobin count. Our results support the superiority of intravenous OK-432 treatment over intramuscular treatment in the growth-accelerating effect on bone marrow cells, especially regarding the neutrophil series.

    This article describes a recent case of ciguatera poisoning treated with intravenous mannitol. Mannitol has been used with good effect in non-controlled studies in acutely severely poisoned patients, but is not described in the treatment of chronic or milder poisoning. Our patient was a 35-year-old Niuean man who had eaten a ciguatoxic fish two weeks previously. His symptoms were not severe but were very unpleasant and restricted his ability to work. He was given a single dose of mannitol (0.66g/kg) as an intravenous infusion over two hours. His symptoms dramatically improved within 24 hours, and within a few days he felt virtually back to his former self. He experienced no side effects to the mannitol. It is suggested that intravenous mannitol may prove to be a useful treatment for mild to moderate ciguatera poisoning, and for patients who present late for treatment.

    Thyroid stimulating immunoglobulins (TSAb) were measured in fifty-four patients with Graves' disease before treatment with either radioiodine (seventeen patients) or propylthiouracil (PTU) (thirty-seven patients) and followed during treatment. After radioiodine TSAb increased to levels exceeding pretreatment values, and became detectable in three of six originally TSAb negative patients. In most patients TSAb decreased during treatment with PTU, and became undetectable after a mean of 12 months in patients above 40 years, and after a mean of 6 months in patients below 40 years. In order to eliminate the presumed causative agent in Graves' disease, antithyroid treatment should be at least 18 months in patients above 40 years, and at least 12 months in patients below 40 years of age. In twenty-nine patients TSAb were measured at cessation of 2 years antithyroid drug therapy. Ten patients were TSAb positive and all except one relapsed. Five of nineteen TSAb negative patients relapsed. Although TSAb positivity predicts relapse, it is not an ideal index of prognosis after antithyroid therapy. (author)

    The effect of melphalan on immunoglobulin G (IgG) production by a human lymphoblastoid cell line (BF) was studied. The amount of secreted IgG and the percentage of cells containing cytoplasmic IgG were measured by immunoassay and cytofluorometry, respectively. Dose-response studies indicated that melphalan concentrations of 2 x 10/sup -8/ M had no effect, while concentrations of 8 x 10/sup -7/ M were totally toxic, after 72-h exposures to the drug. Statistically significant, persistent, alterations in both synthesis and secretion of IgG by BF cells were observed following treatment for 72 h with 4 x 10/sup -7/ M melphalan, and there was an increase in population-doubling time from 24 to 72 h in these drug-treated cells. The percentage of IgG-containing cells in melphalan-treated cultures was significantly decreased as compared to control cultures. IgG secretion was also decreased in these cultures, and the variation in IgG secretion as a function of cellular growth was significantly altered following melphalan treatment. Decreased IgG production following melphalan treatment may be related to altered cell cycle kinetics. Based on immunological analysis, there was no evident alteration in the IgG secreted by melphalan-treated cells, nor did melphalan treatment produce a cellular population lacking IgG entirely.

    The goal of this study was to investigate whether intravenous infusion of 1000 ml 40% calcium borogluconate combined with the oral adminstration of 500 g sodium phosphate leads to a better cure rate and longer-lasting normocalcaemia and normophosphataemia than standard intravenous treatment with 500 ml calcium borogluconate in cows with parturient paresis. Forty recumbent cows with hypocalcaemia and hypophosphataemia were alternately allocated to group A or B. Cows of both groups were treated intravenously with 500 ml 40% calcium borogluconate, and cows of group B additionally received another 500 ml calcium borogluconate via slow intravenous infusion and 500 g sodium phosphate administered via an orogastric tube. Thirty-two cows stood within 8 hours after the start of treatment and 8 did not; of the 32 cows that stood, 18 belonged to group A and 14 to group B (90% of group A vs. 70% of group B; P = 0.23). Seven cows relapsed; of these and the 8 that did not respond to initial treatment, 10 stood after two standard intravenous treatments. Downer cow syndrome occurred in 5 cows, 3 of which recovered after aggressive therapy. The overall cure rate did not differ significantly between groups A and B. Twelve (60%) cows of group A and 14 (70%) cows of group B were cured after a single treatment and of the remaining 14, 11 were cured after two or more treatments. Two downer cows were euthanized and one other died of heart failure during treatment. Serum calcium concentrations during the first eight hours after the start of treatment were significantly higher in group B than in group A, and oral sodium phosphate caused a significant and lasting increase in inorganic phosphate. More cows of group B than group A were cured after a single treatment (P > 0.05). These findings, although not statistically significant, are promising and should be verified using a larger number of cows.

    Full Text Available We report a case of immunoglobulin G4 (IgG4-related retroperitoneal fibrosis (RF with complete remission and no relapses after therapy with steroids and Hochuekkito, a Kampo (i.e. traditional Japanese herbal medicine. A 62-year-old Japanese man was admitted to our hospital for treatment of a retroperitoneal mass detected by computed tomography. The mass had a maximum diameter of 11.0 cm; it involved the left ureter and was associated with left hydronephrosis. After inserting a ureteral stent, we performed a biopsy by laparotomy. Histopathology revealed IgG4-related RF. The lesion disappeared after 7 months of steroid therapy. We subsequently used Hochuekkito as an alternative maintenance treatment because of steroid-related complications. The patient has not relapsed in the 3 years since starting the medication. To the best of our knowledge, this is the first case of IgG4-related RF treated with Hochuekkito as a maintenance treatment.

    2008-04-01

    Full Text Available Immunoglobulin E (IgE is central to the development of allergic diseases. Cross-linking of cell-bound IgE by the allergen leads to the initiation of the inflammatory cascade. Omalizumab, an anti-IgE antibody, forms complexes with free IgE, thereby inhibiting the allergic reaction before its commencement. A survey of the clinical trials performed on omalizumab indicated that this anti-IgE antibody is efficacious and well tolerated in the treatment of separate and concomitant asthma and rhinitis. In patients with poorly controlled asthma, omalizumab reduced the asthma exacerbation and emergency visit rate, along with improving the quality of life. The improvement in asthma control was associated with a reduction of inhaled and oral corticosteroids. Improved nasal symptom scores and a reduced need for antihistamines were observed in patients with allergic rhinitis. Omalizumab was also proven to be effective as an add-on therapy for concomitant asthma and rhinitis. In conclusion, omalizumab provides an integrated approach for the treatment and management of allergic respiratory diseases.

    Background and purpose: To investigate the feasibility of using intravenous contrast-enhanced computed tomography (CT) scans in 3-dimensional conformal radiotherapy (3D-CRT), stereotactic body radiation therapy (SBRT) and intensity-modulated radiotherapy (IMRT) treatment planning for lung cancers, respectively. Materials and methods: Twelve patients with bulky lung tumors and 14 patients with small lung tumors were retrospectively analyzed. Each patient took two sets of CT in the same position with active breathing control (ABC) technique before and after intravenous contrast agent (CA) injections. Bulky tumors were planned with 3D-CRT, while SBRT plans were generated for patients with small tumors based on CT scans with intravenous CA. In addition, IMRT plans were generated for patients with bulky tumors to continue on a planning study. All plans were copied and replaced on the scans without intravenous CA. The radiation doses calculated from the two sets of CTs were compared with regard to planning volumes (PTV), the organ at-risk (OAR) and the lungs using Wilcoxon's signed rank test. Results: In comparisons for 3D-CRT plans, CT scans with intravenous CA reduced the mean dose and the maximum dose of PTV with significant differences (p 95 ) for targets, respectively (p < 0.05). There was no statistical significance for lung parameters between two sets of scans in SBRT plans and IMRT plans. Conclusions: The enhanced CT scans can be used for both target delineation and treatment planning in 3D-CRT. The dose difference caused by intravenous CA is small. But for SBRT and IMRT, the minimum irradiation dose in targets may be estimated to be increased up to 2.71% while the maximum dose may be estimated to be decreased up to 1.36%. However, the difference in dose distribution in most cases were found to be clinical tolerable.

    A 65-year-old pluripathological woman attended our hospital with a cutaneous eruption of sudden appearance after vancomycin treatment. She presented targetoid lesions affecting approximately 25-30% of her body surface, large erosions with mucosal lesions and positive Nikolsky sign. Under the initial clinical suspicion of toxic epidermal necrolysis (TEN), and considering the recent literature of successful use of etanercept in these cases, she was treated with a single dose of this antitumour necrosis factor (anti-TNF) agent. Subsequently, the exanthema progression stopped and resolution of the lesions happened in a few days. Later on, histopathology revealed a subepidermal blister with dense neutrophilic infiltrate and linear deposits of immunoglobulin A (IgA) on the dermoepidermal junction, allowing us to establish the diagnosis of drug-induced linear IgA dermatosis mimicking TEN. Linear IgA dermatosis can have severe clinical manifestations, even mimicking TEN, and can have high mortality, especially in drug-induced cases. We have not found any other report of linear IgA dermatosis treated with etanercept in the English literature. Anti-TNF medications could represent useful therapeutic alternatives in this dermatosis. © 2017 British Association of Dermatologists.

    Infective endocarditis is a life threatening complication of intravenous drug abuse, which continues to be a major burden with inadequately characterised long-term outcomes. We reviewed our institutional experience of surgical treatment of infective endocarditis in active intravenous drug abusers with the aim of identifying the determinants long-term outcome of this distinct subgroup of infective endocarditis patients. A total of 451 patients underwent surgery for infective endocarditis between January 1993 and July 2013 at the University Hospital of Heidelberg. Of these patients, 20 (7 female, mean age 35 ± 7.7 years) underwent surgery for infective endocarditis with a history of active intravenous drug abuse. Mean follow-up was 2504 ± 1842 days. Staphylococcus aureus was the most common pathogen detected in preoperative blood cultures. Two patients (10%) died before postoperative day 30. Survival at 1, 5 and 10 years was 90%, 85% and 85%, respectively. Freedom from reoperation was 100%. Higher NYHA functional class, higher EuroSCORE II, HIV infection, longer operating time, postoperative fever and higher requirement for red blood cell transfusion were associated with 90-day mortality. In active intravenous drug abusers, surgical treatment for infective endocarditis should be performed as extensively as possible and be followed by an aggressive postoperative antibiotic therapy to avoid high mortality. Early surgical intervention is advisable in patients with precipitous cardiac deterioration and under conditions of staphylococcal endocarditis. However, larger studies are necessary to confirm our preliminary results.

    To evaluate the efficacy and limitation of intra-arterial urokinase (IAUK) infusion for treatment of acute cerebral stroke. Twenty-seven acute cerebral stroke patients treated with IAUK infusion within six hours of stroke onset were reviewed. All patients showed normal initial brain findings on CT. In 21 patients, urokinase(5-15 x 10 5 IU) was administered through a microcatheter placed into or proximal to occluded segment. Mechanical disruption of thrombus by guidewire was performed in 17 patients. Angiographic and clinical responses and complications after IAUK infusion, were evaluated and the results were compared with those of intravenous heparin(N=19) and urokinase infusion(N=19). Complete or partial angiographic recanalization of occluded segment was found in 18 patients (67%), and neurologic improvement was followed in 14 patients(52%). The degree of improvement on the stroke scale score after IAUK infusion was statistically more significant(p<0.05) than that shown after intravenous heparin and urokinase infusion. Complications after IAUK infusion were large(15%) and small amount intracerebral hemorrhage(15%), contrast leakage into brain parenchyma(11%), and gastrointestinal bleeding(4%). Between the IAVK and the intravenous urokinase infusion group, differences in extent and types of complications were statistically insignificant, but were significantly higher in those two groups than in the intravenous heparin infusion group. IAUK infusion may be effective for the treatment of acute cerebral stroke

    There is increasing evidence supporting that neuromyelitis optica (NMO) is an inflammatory humoral mediated disorder associated with NMO-IgG/AQP-4 antibodies. However, little is known about the subsets of B cells and T cells that contribute to the pathogenesis or therapy response. To describe the clinical and immunological changes associated with intravenous immunoglobulins (IV-Igs) plus rituximab (RTX) in a patient with a severe acute attack of NMO and intrathecal synthesis of NMO-IgG/AQP-4, who previously did not respond to intravenous methylprednisolone and plasma exchange. We sequentially analysed the levels of NMO-IgG/AQP-4 by immunohistochemistry, and B and T cells subsets by multiparametric flow-cytometry, in the CSF and peripheral blood (PB), before and alter IV-Igs plus RTX therapy. In the CSF before treatment, and compared with PB, there was a higher percentage of CD4(+) T cells and a lower percentage of CD8(+) T cells and CD19(+) B cells. After therapy, the percentage of CD4(+) T cells remained high, and that of CD8(+) T cells increased. The observed decrease in the percentage of CD19(+) B cells was lower than in the PB. When the CSF was compared, it was found that the percentage of effector-memory and effector CD8(+) T cells had increased after therapy, and that of IgM memory B cells and switched-memory B cells decreased. The observed changes paralleled the decrease of NMO-IgG/AQP-4 results to negative and the clinical improvement. Our findings confirm that, besides intrathecal humoral immune response against AQP4, B and T cell subsets are involved in the modulation of inflammation within and outside the central nervous system.

    Fiorello, Christine V

    2017-03-01

    Foot infections are a common problem among seabirds in wildlife rehabilitation. Pododermatitis and digital infections are often challenging to treat because of the presence of suboptimal substrates, abnormal weight-bearing due to injuries, and suboptimal nutritional or health status. Seabirds represent the majority of animals requiring rehabilitation after oil spills, and foot problems are a common reason for euthanasia among these birds. Antibiotic intravenous regional perfusion therapy is frequently used in humans and other species to treat infections of the distal extremities, but it has not been evaluated in seabirds. During the 2015 Refugio oil spill response, four birds with foot lesions (pododermatitis, osteomyelitis, or both) were treated with ampicillin/sulbactam administered intravenously to the affected limb(s) in addition to systemic antibiotics and anti-inflammatories. Three of the birds, all brown pelicans ( Pelecanus occidentalis ) recovered rapidly and were released. Two of these birds had acute pododermatitis and were treated once with intravenous regional perfusion. They were released approximately 3 wk after the perfusion therapy. The third pelican had osteomyelitis of a digit. It was treated twice with intravenous regional perfusion and was released about 1 mo after the initial perfusion therapy. The fourth bird, a Pacific loon ( Gavia pacifica ), was treated once with perfusion therapy but did not respond to treatment and was euthanatized. No serious adverse effects were observed. This technique should be explored further in avian species.

  18. The possible role of intravenous lipid emulsion in the treatment of chemical warfare agent poisoning

    Directory of Open Access Journals (Sweden)

    Arik Eisenkraft

    Full Text Available Organophosphates (OPs are cholinesterase inhibitors that lead to a characteristic toxidrome of hypersecretion, miosis, dyspnea, respiratory insufficiency, convulsions and, without proper and early antidotal treatment, death. Most of these compounds are highly lipophilic. Sulfur mustard is a toxic lipophilic alkylating agent, exerting its damage through alkylation of cellular macromolecules (e.g., DNA, proteins and intense activation of pro-inflammatory pathways. Currently approved antidotes against OPs include the peripheral anticholinergic drug atropine and an oxime that reactivates the inhibited cholinesterase. Benzodiazepines are used to stop organophosphate-induced seizures. Despite these approved drugs, efforts have been made to introduce other medical countermeasures in order to attenuate both the short-term and long-term clinical effects following exposure. Currently, there is no antidote against sulfur mustard poisoning. Intravenous lipid emulsions are used as a source of calories in parenteral nutrition. In recent years, efficacy of lipid emulsions has been shown in the treatment of poisoning by fat-soluble compounds in animal models as well as clinically in humans. In this review we discuss the usefulness of intravenous lipid emulsions as an adjunct to the in-hospital treatment of chemical warfare agent poisoning.

    Severe malaria is a medical emergency associated with high mortality. Adequate treatment requires initial parenteral therapy for fast parasite clearance followed by longer acting oral antimalarial drugs for cure and prevention of recrudescence. In a randomized controlled clinical trial, we evaluated the 42-day parasitological outcomes of severe malaria treatment with intravenous artesunate (AS) or intravenous quinine (QNN) followed by oral artemisinin based combination therapy (ACT) in children living in a high malaria transmission setting in Eastern Uganda. We enrolled 300 participants and all were included in the intention to treat analysis. Baseline characteristics were similar across treatment arms. The median and interquartile range for number of days from baseline to parasite clearance was significantly lower among participants who received intravenous AS (2 (1-2) vs 3 (2-3), P malaria symptoms. In this high transmission setting, we observed adequate initial treatment outcomes followed by very high rates of malaria re-infection post severe malaria treatment. The impact of recurrent antimalarial treatment on the long term efficacy of antimalarial regimens needs to be investigated and surveillance mechanisms for resistance markers established since recurrent malaria infections are likely to be exposed to sub-therapeutic drug concentrations. More strategies for prevention of recurrent malaria infections in the most at risk populations are needed. The study was registered with the Pan African Clinical Trial Registry ( PACTR201110000321348 ).

    1993-12-01

    We compared the biochemical effects and safety of pamidronate (30 mg a day for 3 consecutive days) versus clodronate (300 mg a day for 3 consecutive days) via intravenous infusion in 14 patients with Paget's disease of bone (PDB). Both drugs induced a decrease in serum alkaline phosphatase levels as well as the elimination of hydroxyproline from urine, an effect most marked in the group treated with pamidronate. The response was maintained for 6 months after the infusion in the majority of the patients. No relevant side effects were found, except post-infusion febricula and in one patient, self-limiting thrombopenia 6 months after the infusion. We conclude that the intravenous infusion of either of the two drugs may constitute a safe and effective alternative for treatment of PDB with marked biochemical activity or resistant to conventional therapy.

This case series includes 10 client-owned animals, 9 dogs and 1 cat, that underwent treatment with ILE for a variety of severe intoxications over a 4-year period. History, physical examination findings, clinical signs, clinicopathological test results, treatment, response to treatment, and outcome were recorded. Eight of the 10 patients survived to discharge. The toxicities included in this case series were baclofen, ivermectin and spinosad plus milbemycin oxime, baclofen and tadalafil, carbamate, methamphetamine, dextroamphetamine sulfate, amlodipine, bromethalin, and organophosphate. The two patients who died were intoxicated with bromethalin and an organophosphate. Six of the 10 patients developed lipemia secondary to ILE administration, and there were no other known adverse effects. Overall, ILE was a safe therapeutic option. This case series provides clinical evidence of successful treatment with ILE as an antidote for previously unpublished toxicities (amlodipine, carbamate, methamphetamine, and dextroamphetamine sulfate, additional evidence of success in treating baclofen and ivermectin toxicosis, as well as unsuccessful treatment of bromethalin and organophosphate toxicities.Keywords: intravenous lipid emulsion, toxicity, amlodipine

    Recent reports warn that the worldwide cell culture capacity is insufficient to fulfill the increasing demand for human protein drugs. Production in milk of transgenic animals is an attractive alternative. Kilogram quantities of product per year can be obtained at relatively low costs, even in small animals such as rabbits. We tested the long-term safety and efficacy of recombinant human -glucosidase (rhAGLU) from rabbit milk for the treatment of the lysosomal storage disorder Pompe disease. The disease occurs with an estimated frequency of 1 in 40,000 and is designated as orphan disease. The classic infantile form leads to death at a median age of 6 to 8 months and is diagnosed by absence of alpha-glucosidase activity and presence of fully deleterious mutations in the alpha-glucosidase gene. Cardiac hypertrophy is characteristically present. Loss of muscle strength prevents infants from achieving developmental milestones such as sitting, standing, and walking. Milder forms of the disease are associated with less severe mutations and partial deficiency of alpha-glucosidase. In the beginning of 1999, 4 critically ill patients with infantile Pompe disease (2.5-8 months of age) were enrolled in a single-center open-label study and treated intravenously with rhAGLU in a dose of 15 to 40 mg/kg/week. Genotypes of patients were consistent with the most severe form of Pompe disease. Additional molecular analysis failed to detect processed forms of alpha-glucosidase (95, 76, and 70 kDa) in 3 of the 4 patients and revealed only a trace amount of the 95-kDa biosynthetic intermediate form in the fourth (patient 1). With the more sensitive detection method, 35S-methionine incorporation, we could detect low-level synthesis of -glucosidase in 3 of the 4 patients (patients 1, 2, and 4) with some posttranslation modification from 110 kDa to 95 kDa in 1 of them (patient 1). One patient (patient 3) remained totally deficient with both detection methods (negative for cross

    A ketogenic diet has been used successfully to treat intractable epilepsy. However, the role of early intravenous initiation of ketogenic diet in the acute phase of super-refractory status epilepticus is not well-described. An intravenous ketogenic diet was administered to a boy with super-refractory status epilepticus. At 24 hours after intravenous ketogenic diet, moderate ketosis appeared, and thiamylal was successfully weaned at 70 hours after admission. An intravenous ketogenic regimen led to subsequent ketosis and seizure control in a child with super-refractory status epilepticus. Early induction of ketosis may be a novel strategy to effectively treat super-refractory status epilepticus. Although there are few data regarding the early use of intravenous ketogenic diet in the treatment of super-refractory status epilepticus, it may be considered an alternative option.

    Full Text Available BACKGROUND AND OBJECTIVE: Postoperative pain treatment in mastectomy remains a major challenge despite the multimodal approach. The aim of this study was to investigate the analgesic effect of intravenous lidocaine in patients undergoing mastectomy, as well as the postoperative consumption of opioids. METHODS: After approval by the Human Research Ethics Committee of the Instituto de Medicina Integral Prof. Fernando Figueira in Recife, Pernambuco, a randomized, blind, controlled trial was conducted with intravenous lidocaine at a dose of 3 mg/kg infused over 1 h in 45 women undergoing mastectomy under general anesthesia. One patient from placebo group was. RESULTS: Groups were similar in age, body mass index, type of surgery, and postoperative need for opioids. Two of 22 patients in lidocaine group and three of 22 patients in placebo group requested opioid (p = 0.50. Pain on awakening was identified in 4/22 of lidocaine group and 5/22 of placebo group (p = 0.50; in the post-anesthetic recovery room in 14/22 and 12/22 (p = 0.37 of lidocaine and placebo groups, respectively. Pain evaluation 24 h after surgery showed that 2/22 and 3/22 patients (p = 0.50 of lidocaine and placebo groups, respectively, complained of pain. CONCLUSION: Intravenous lidocaine at a dose of 3 mg/kg administered over a period of an hour during mastectomy did not promote additional analgesia compared to placebo in the first 24 h, and has not decreased opioid consumption. However, a beneficial effect of intravenous lidocaine in selected and/or other therapeutic regimens patients cannot be ruled out.

    Ketogenic diet (KD) has been used to treat refractory status epilepticus (RSE). KD is a high-fat, restricted-carbohydrate regimen that may be administered with different fat to protein and carbohydrate ratios (3:1 and 4:1 fat to protein and carbohydrate ratios). Other ketogenic regimens have a lower fat and higher protein and carbohydrate ratio to improve taste and thus compliance to treatment. We describe a case of RSE treated with intravenous KD in the Pediatric Intensive Care Unit (PICU). An 8-year-old boy was referred to the PICU because of continuous tonic-clonic and myoclonic generalized seizures despite several antiepileptic treatments. After admission he was intubated and treated with intravenous thiopental followed by ketamine. Seizures continued with frequent myoclonic jerks localized on the face and upper arms. EEG showed seizure activity with spikes on rhythmic continuous waves. Thus we decided to begin KD. The concomitant ileus contraindicated KD by the enteral route and we therefore began IV KD. The ketogenic regimen consisted of conventional intravenous fat emulsion, plus dextrose and amino-acid hyperalimentation in a 2:1 then 3:1 fat to protein and carbohydrate ratio. Exclusive IV ketogenic treatment, well tolerated, was maintained for 3 days; peristalsis then reappeared so KD was continued by the enteral route at 3:1 ratio. Finally, after 8 days and no seizure improvement, KD was deemed unsuccessful and was discontinued. Our experience indicates that IV KD may be considered as a temporary "bridge" towards enteral KD in patients with partial or total intestinal failure who need to start KD. It allows a prompt initiation of KD, when indicated for the treatment of severe diseases such as RSE. Copyright © 2016 European Paediatric Neurology Society. Published by Elsevier Ltd.

    Full Text Available Introduction: Puncture wound in diagnostic interventions permits the entry of bacteria into the skin or soft tissue, thus precipitating nosocomial infection, such as erysipelas. There are other risk factors of nosocomial infections including old age, immunosuppressive drugs, and underlying diseases. Pemphigus foliaceus (PF is an autoimmune disease with corticosteroid treatment as the mainstay therapy, which could cause immunosuppression and predispose patients to infection. The objective of this paper was to report erysipelas as one of the manifestations of nosocomial infection in patients under immunosuppressive therapy. Case: A case of erysipelas acquired on the 9th day of hospitalization in a PF patient underwent intravenous dexamethasone injection, with history of puncture wounds on the previous day on the site of erysipelas was reported. The clinical findings of erysipelas were well defined, painful erythema and edema that felt firm and warm on palpation, with blisters and pustules on top. Gram staining from the pustules and blisters fluid revealed Gram (+ cocci. Patient was given 2 grams intravenous ceftriaxone for 7 days and saline wet compress. Improvement on the erysipelas was seen the day after ceftriaxone injection. The patient was discharged after 12 days of hospitalization with improvement both on the PF and the erysipelas. On the next visit 7 days later, the erysipelas lesion disappeared. Conclusion: Puncture wound and immunosuppresive treatment are the factors that could cause erysipelas as a nosocomial infection, and an appropriate treatment of the infection would decrease the functional disability of the patient.

    The aim of this study was to compare the efficacy and safety of 3 nonsteroidal anti-inflammatory drugs-intravenous tenoxicam, lornoxicam, and dexketoprofen trometamol-for the treatment of patients with renal colic. We conducted a prospective double-blind randomized trial of consecutive adult patients who presented to the emergency department with a chief complaint of acute flank pain and had a clinical diagnosis of suspected acute renal colic. Patients were randomly allocated to receive an intravenous bolus of tenoxicam, lornoxicam, or dexketoprofen trometamol in a blinded fashion. Primary outcome measure of the study was visual analog scale (VAS) score difference at 30 minutes. Secondary outcome measures were VAS scores at 5, 15, and 120 minutes as well as rescue analgesic need at 30 minutes and adverse events during the follow-up period. A total of 445 patients were screened, and 123 patients were enrolled in the study. The mean age was 36 ± 10 years. The mean reduction in VAS pain scores at 30 minutes was 42 ± 26 mm for tenoxicam, 57 ± 23 mm for lornoxicam, and 52 ± 25 mm for dexketoprofen (P = .047). Lornoxicam demonstrated the fastest rate of VAS score reduction over the first 30 minutes. The mean reduction values in VAS pain scores at 5, 15, and 120 minutes were similar among the 3 groups. Rescue analgesics at 30 minutes were required by 16 patients (39%) receiving tenoxicam, 10 patients (24%) receiving lornoxicam, and 8 patients (19%) receiving dexketoprofen (P = .121). No serious adverse events were observed. Intravenous tenoxicam, lornoxicam, and dexketoprofen are all effective in the treatment of renal colic, although lornoxicam appears to reduce VAS pain scores with the fastest rate in this comparison.

    Full Text Available Background and Purpose: Multiple system atrophy with predominant cerebellar ataxia is a disabling neurologic disease. However, effective management has not yet been established. We conducted a short-term, open-label preliminary study to assess the benefits of intravenous amantadine treatment in patients with probable multiple system atrophy with predominant cerebellar ataxia. Methods: Twenty patients (10 male, 10 female with probable multiple system atrophy with predominant cerebellar ataxia received 400 mg of amantadine by intravenous per day for 5 days. Ataxia severity was evaluated by the International Cooperative Ataxia Rating Scale before and after intravenous amantadine therapy and all subjects reported subjective improvement after intravenous amantadine treatment using a patient global impression scale. We analyzed the total and subscale scores by the ataxia scale and patient global impression scale. Results: The mean age was 57.4 years (range: 47–72 and the mean disease duration was 30.8 months (range: 11–79. The ataxia severity significantly decreased after intravenous amantadine therapy from 42.5 to 37.3 (p < 0.001. The mean patient global impression scale for improvement was 2.9 and there were no side effects of intravenous amantadine treatment observed. When we assessed responders, the duration of intravenous amantadine effect was more than 1 month in 4 subjects of 7 responders. Conclusions: Our findings suggest that intravenous amantadine treatment can be a safe management option in cerebellar ataxia, although the mechanism is unclear. Thus, further double-blind, long-term studies with a larger sample size are needed.

    Full Text Available Objectives: To evaluate the knowledge of ophthalmologists regarding local anesthesia toxicity syndrome (LATS and intravenous lipid emulsion used in treatment, and to raise awareness of this issue. Materials and Methods: A questionnaire comprising 14 questions about demographics, local anesthesia (LA use, toxicity, and treatment methods was administered to ophthalmologists at different hospitals. Results: The study included 104 ophthalmologists (25% residents, 67.3% specialists, 7.7% faculty members with a mean age of 35.71±6.53 years. The highest number of participants was from state hospitals (65.4%, and 34.6% of the physicians had been working in ophthalmology for more than 10 years. Seventy-six percent of the participants reported using LA every day or more than twice a week, but 56.7% had received no specific training on this subject. No statistically significant difference was observed between different education levels and the rates of training (p=0.419. Bupivacaine was the most preferred LA and the majority of respondents (97.1% did not use a test dose. Allergy (76% and hypotension (68.3% were the most common responses for early findings of LATS, while cardiac arrest (57.4% and hepatotoxicity (56.4% were given for late findings. The most common responses concerning the prevention of LATS included monitorization (72.4% and use of appropriate doses (58.2%. Symptomatic treatment was selected by 72.4% of respondents and cardiopulmonary resuscitation and antihistamine treatment by 58.8%. Of the ophthalmologists in the study, 62.5% had never encountered LATS. The use of 20% intravenous lipid emulsion therapy for toxicity was known by 65% of the physicians, but only 1 participant stated having used it previously. Conclusion: The importance of using 20% lipid emulsion in LATS treatment and having it available where LA is administered must be emphasized, and there should be compulsory training programs for ophthalmologists on this subject.

    Paracetamol poisoning is common worldwide. It is treated with intravenous acetylcysteine, but the standard regimen is complex and associated with frequent adverse effects related to concentration, which can cause treatment interruption. We aimed to ascertain whether adverse effects could be reduced with either a shorter modified acetylcysteine schedule, antiemetic pretreatment, or both. We undertook a double-blind, randomised factorial study at three UK hospitals, between Sept 6, 2010, and Dec 31, 2012. We randomly allocated patients with acute paracetamol overdose to either the standard intravenous acetylcysteine regimen (duration 20·25 h) or a shorter (12 h) modified protocol, with or without intravenous ondansetron pretreatment (4 mg). Masking was achieved by infusion of 5% dextrose (during acetylcysteine delivery) or saline (for antiemetic pretreatment). Randomisation was done via the internet and included a minimisation procedure by prognostic factors. The primary outcome was absence of vomiting, retching, or need for rescue antiemetic treatment at 2 h. Prespecified secondary outcomes included a greater than 50% increase in alanine aminotransferase activity over the admission value. Analysis was by intention to treat. This trial is registered with ClinicalTrials.gov (identifier NCT01050270). Of 222 patients who underwent randomisation, 217 were assessable 2 h after the start of acetylcysteine treatment. Vomiting, retching, or need for rescue antiemetic treatment at 2 h was reported in 39 of 108 patients assigned to the shorter modified protocol compared with 71 of 109 allocated to the standard acetylcysteine regimen (adjusted odds ratio 0·26, 97·5% CI 0·13-0·52; ppoisoning, a 12 h modified acetylcysteine regimen resulted in less vomiting, fewer anaphylactoid reactions, and reduced need for treatment interruption. This study was not powered to detect non-inferiority of the shorter protocol versus the standard approach; therefore, further research is needed

    Duchenne muscular dystrophy (DMD) is a severe hereditary myopathy. Standard treatment by glucocorticosteroids is limited because of numerous side effects. The aim of this study was to test immunomodulation by human immunoglobulin G (IgG) as treatment in the experimental mouse model (mdx) of DMD. 2 g/kg human IgG compared to human albumin was injected intraperitoneally in mdx mice at the age of 3 and 7 weeks. Advanced voluntary wheel running parameters were recorded continuously. At the age of 11 weeks, animals were killed so that blood, diaphragm, and lower limb muscles could be removed for quantitative PCR, histological analysis and ex vivo muscle contraction tests. IgG compared to albumin significantly improved the voluntary running performance and reduced muscle fatigability in an ex vivo muscle contraction test. Upon IgG treatment, serum creatine kinase values were diminished and mRNA expression levels of relevant inflammatory markers were reduced in the diaphragm and limb muscles. Macrophage infiltration and myopathic damage were significantly ameliorated in the quadriceps muscle. Collectively, this study demonstrates that, in the early disease course of mdx mice, human IgG improves the running performance and diminishes myopathic damage and inflammation in the muscle. Therefore, IgG may be a promising approach for treatment of DMD. Two monthly intraperitoneal injections of human immunoglobulin G (IgG) improved the early 11-week disease phase of mdx mice. Voluntary running was improved and serum levels of creatine kinase were diminished. In the skeletal muscle, myopathic damage was ameliorated and key inflammatory markers such as mRNA expression of SPP1 and infiltration by macrophages were reduced. The study suggests that IgG could be explored as a potential treatment option for Duchenne muscular dystrophy and that pre-clinical long-term studies should be helpful. © 2015 International Society for Neurochemistry.

    To describe the natural history, antenatal and postnatal therapy, and clinical outcomes of Australian patients with fetomaternal/neonatal alloimmune thrombocytopenia (NAIT) recorded in the Australian NAIT registry. Analysis of registry data of Australian mothers treated antenatally for NAIT and any fetus/newborn with thrombocytopenia (TCP) and maternal human platelet antigen (HPA) antibodies. Ninety four potential cases (91 pregnancies; three twin pregnancies) were registered between December 2004 and September 2015 with 76 confirmed or treated as NAIT. NAIT was frequently unanticipated (44 cases, 58%), whilst 32 cases (42%) were anticipated due to personal or family history. In 70/76 cases, the diagnosis of NAIT was made based on HPA antibody results; anti-HPA-1a was most commonly detected (58/70, 82%), followed by anti-HPA-5b (5/70, 7%). Intracranial haemorrhage (ICH) was detected in seven cases (9%). Maternal antenatal therapy resulted in improved clinical outcomes. For antenatally treated cases, whilst 10/29 (34%) neonates had severe TCP, only one ICH was detected. This study provides data on contemporary "real world" management of Australian mothers and babies with NAIT. Antenatal IVIG therapy was associated with better neonatal outcomes. Maternal side-effects and treatment costs were substantial.

    Many of the elderly in nursing homes are very ill and have a reduced quality of life. Life expectancy is often hard to predict. Decisions about life-prolonging treatment should be based on a professional assessment of the patient's best interest, assessment of capacity to consent, and on the patient's own wishes. The purpose of this study was to investigate and compare how these types of decisions were made in nursing homes and in hospital wards. Using a questionnaire, we studied the decision-making process for 299 nursing home patients who were treated for dehydration using intravenous fluids, or for bacterial infections using intravenous antibiotics. We compared the 215 (72%) patients treated in nursing homes to the 84 (28%) nursing home patients treated in the hospital. The patients' capacity to consent was considered prior to treatment in 197 (92%) of the patients treated in nursing homes and 56 (67%) of the patients treated in hospitals (p nursing homes than in hospital (90% vs. 52%). Next of kin and other health personnel were also more rarely involved when the nursing home patient was treated in hospital. Whether advance care planning had been carried out, was more often unknown in the hospital (69% vs. 17% in nursing homes). Hospital doctors expressed more doubt about the decision to admit the patient to the hospital than about the treatment itself. This study indicates a potential for improvement in decision-making processes in general, and in particular when nursing home patients are treated in a hospital ward. The findings corroborate that nursing home patients should be treated locally if adequate health care and treatment is available. The communication between the different levels of health care when hospitalization is necessary, must be better.

    Severe malaria remains a major cause of mortality and morbidity for children living in many tropical regions. With the emergence of strains of Plasmodium falciparum resistant to both chloroquine and quinine, alternative antimalarial agents are required. The artemisinin group of compounds are rapidly effective in severe disease when given by intramuscular or intravenous injection. However, these routes of administration are not always available in rural areas. In an open, randomized comparison 109 Vietnamese children, aged between 3 months and 14 years, with severe P.falciparum malaria, were allocated at random to receive artemisinin suppositories followed by mefloquine (n = 37), intramuscular artesunate followed by mefloquine (n = 37), or intravenous quinine followed by pyrimethamine/sulfadoxine (n = 35). There were 9 deaths: 2 artemisinin, 4 artesunate and 5 quinine-treated children. There was no difference in fever clearance time, coma recovery, or length of hospital stay among the 3 groups. However, parasite clearance times were significantly faster in artemisinin and artesunate-treated patients than in those who received quinine (P children receiving these drugs had lower peripheral reticulocyte counts by day 5 of treatment than those in the quinine group (P = 0.011). No other adverse effect or toxicity was found. There was no treatment failure in these 2 groups, but 4 patients in the quinine group failed to clear their parasites within 7 d of starting treatment and required alternative antimalarial therapy. Artemisinin suppositories are easy to administer, cheap, and very effective for treating children with severe malaria. In rural areas where medical facilities are lacking these drugs will allow antimalarial therapy to be instituted earlier in the course of the disease and may therefore save lives.

    Full Text Available Elda Righi, Alessia Carnelutti, Antonio Vena, Matteo Bassetti Infectious Diseases Division, Santa Maria della Misericordia University Hospital, Udine, Italy Abstract: The increase in hospitalization due to acute bacterial skin and skin structure infections (ABSSSI caused by resistant pathogens supports the need for new treatment options. Antimicrobial options for ABSSSI that provide broad-spectrum coverage, including gram-negative pathogens and multidrug-resistant gram-positive bacteria, such as methicillin-resistant Staphylococcus aureus (MRSA, are limited. Delafloxacin is a novel fluoroquinolone available as intravenous and oral formulations and is characterized by an increased efficacy in acidic environments and activity on bacterial biofilm. Delafloxacin displays enhanced in vitro activity against MRSA, and enterococci, while maintaining efficacy against gram-negative pathogens and anaerobes. Delafloxacin has been studied for the treatment of ABSSSI and respiratory infections. Phase III studies have demonstrated noninferiority of delafloxacin compared to vancomycin, linezolid, tigecycline, and the combination of vancomycin plus aztreonam in the treatment of ABSSSI. Due to its favorable pharmacokinetic characteristics, the wide spectrum of action, and the potential for sequential therapy, delafloxacin represents a promising option in the empirical and targeted treatment of ABSSSI, both in hospital- and in community-based care.

    Full Text Available Abstract Background Intravenous (IV artesunate is the treatment of choice for severe malaria. In Europe, however, no GMP-manufactured product is available and treatment data in European travellers are scarce. Fortunately, artesunate became available in the Netherlands and Belgium through a named patient programme. This is the largest case series of artesunate treated patients with severe malaria in Europe. Methods Hospitalized patients treated with IV artesunate between November 2007 and December 2010 in the Netherlands and Belgium were retrospectively evaluated. Patient characteristics, treatment and clinical outcome were recorded on a standardized form and mortality, parasite clearance times and the occurrence of adverse events were evaluated. Results Of the 68 treated patients, including 55 with severe malaria, two patients died (2/55 = 3.6%. The mean time to 50% parasite clearance (PCT50, 90% and 99% were 4.4 hours (3.9 - 5.2, 14.8 hours (13.0 - 17.2, and 29.5 hours (25.9 - 34.4 respectively. Artesunate was well tolerated. However, an unusual form of haemolytic anaemia was observed in seven patients. The relationship with artesunate remains uncertain. Conclusions Data from the named patient programme demonstrate that IV artesunate is effective and well-tolerated in European travellers lacking immunity. However, increased attention needs to be paid to the possible development of haemolytic anaemia 2-3 weeks after start of treatment. Treatment of IV artesunate should be limited to the period that IV treatment is required and should be followed by a full oral course of an appropriate anti-malarial drug.

Jadad Scale was used to evaluate the quality of literatures. Meta-analysis was performed by using RevMan 5.3 software. Results There were a total of 258 records after preliminary searching, and 6 RCTs involving 766 episodes were finally included after excluding duplicate ones and those which did not meet the inclusion criteria. The results were as follows: 1 midazolam via intranasal administration was as effective as intravenous diazepam in achieving seizure control in children (RD = -0.070, 95%CI: -0.200—0.060, P = 0.290. However, non-intravenous (intranasal or buccal midazolam showed better effects on seizure control than rectal diazepam (RD = 0.170, 95% CI: 0.030—0.320; P = 0.020. 2 The mean time from arrival at hospital to cessation was not significantly different between intranasal midazolam and intravenous diazepam (SMD = -1.570, 95%CI: -3.280—0.140; P = 0.070. 3 There was no statistical difference between intranasal midazolam and intravenous diazepam for the time from giving drug to cessation (SMD = 0.240, 95%CI: -0.110—0.590; P = 0.170. 4 There was no statistical difference on the occurrence rate of adverse drug reactions between non-intravenous midazolam and intravenous or non-intravenous diazepam (RD = -0.010, 95% CI: -0.030—0.200; P = 0.500.  Conclusions Non-intravenous midazolam is safe and effective in the treatment for status epilepticus in children.

    Chronic pulsatile subcutaneous administration of low doses of gonadotrophin releasing hormone (GnRH) is an effective therapy for men with hypogonadotrophic hypogonadism. Hypersensitivity reactions to GnRH are rare. We wish to report hypersensitivity reactions with intravenous GnRH after low dose subcutaneous pulsatile GnRH treatment in two men with hypogonadotrophic hypogonadism due to suprasellar disease.

    To compare the clinical efficacy and safety of rectal dihydroartemisinin (DATM--Cotecxin) and intravenous quinine in the treatment of severe malaria in children and adults. Moi Teaching and Referral Hospital, Eldoret, Kenya between July and November 1998. A total of sixty seven patients aged two to sixty years with severe malaria were studied. This was an open randomised comparative clinical trial. These were parasite clearance time, fever clearance time, efficacy and the side effect profile of the two drugs. The two groups were comparable on admission on the clinical and laboratory parameters. The parasite clearance time was shorter in the rectal DATM group than quinine group. There was no statistical difference on the fever clearance time and cure rates in the two groups. The adverse reaction profile was better with rectal DATM than with quinine, tinnitus observed more in the quinine group. Rectal DATM is faster in parasite clearance than quinine and is a safe and convenient alternative to quinine in the treatment of severe malaria.

    Paradoxical hyperactivity (PH) is a known complication of sedation in children, especially with barbiturates such as pentobarbital. The accompanying inconsolable irritability and agitation, similar to behaviors reported in children with attention deficit hyperactivity disorder (ADHD), is uncomfortable for the child and anxiety-provoking for parents and health-care workers. Our objective was to describe our experience with oral (PO) and intravenous (IV) caffeine as a treatment for sedation-induced PH. From January 2000 to April 2003, 19,894 children were sedated in our institution for radiology procedures. Of these, 360 children were diagnosed with PH. A total of 229 children exhibiting symptoms of PH after sedative administration were treated with PO caffeine ( n=88; 43 boys, 45 girls; mean age 4.5 years, mean weight 18.7 kg) or IV caffeine ( n=131; 73 boys, 58 girls; mean age 4.8 years, mean weight 20.1 kg) or both ( n=10; 8 boys, 2 girls; mean age 5.0 years, mean weight 19.9 kg). A positive effect was defined as a decrease in agitation, crying, or hyperactivity within 40 min of caffeine administration. A control group ( n=45) was obtained from those 141 children who experienced post-sedation PH but were not treated with caffeine, and matched for age and sex with samples of children treated with IV caffeine ( n=45) and PO caffeine ( n=45). Children treated intravenously received the equivalent of 20 mg/kg caffeine citrate (to a maximum of 200 mg). Of those treated with IV caffeine, 82/131 (63%) showed a positive effect, and returned to baseline behavioral status after an average of 33 min (SD=23 min). The untreated control group required a significantly longer time to recover ( Pcaffeine. Children treated orally received approximately 1.0-2.5 mg/kg caffeine in Mountain Dew (Pepsi-Cola Company), and 36/88 (41%) showed a positive effect and returned to baseline behavioral status after an average of 42 min (SD=27 min). Of the 10 children treated with both PO and IV

    Sporotrichosis is an important subcutaneous mycosis, with an increasing worldwide incidence. However, few data are available regarding the immunological aspects of Sporothrix schenckii infection, particularly the humoral responses to the fungus. In this study we measured immunoglobulin G (IgG), IgM, and IgA in sera from 41 patients with sporotrichosis before antifungal treatment and from another 35 patients with sporotrichosis during itraconazole treatment by using a recently described S. schenckii exoantigen enzyme-linked immunosorbent assay (ELISA). More than 95% of patients had detectable IgA antibodies, and more than 85% had IgM and IgG antibodies before treatment. The number of patients with IgG antibodies increased to 91% during treatment. Conversely, significantly fewer samples from treated patients were positive for IgM (71%) and IgA (89%). Overall, 78% of patients had detectable levels of all isotypes tested at diagnosis, and this percentage dropped to 62.9% in patients receiving itraconazole. Testing of all three isotypes improved the sensitivity; at least two isotypes were detected in 93% of patients before and 89% after treatment. The reactivity of 94 sera from patients with other diseases and healthy individuals was also tested. Cross-reactivity occurred in 33% of the heterologous sera. Most of them were positive only in one isotype, 8.5% were positive for at least two isotypes, and only one serum (1.1%) was positive for the three isotypes. Antibodies produced during S. schenckii infection are diverse, and we demonstrate that an exoantigen ELISA for the detection of combinations of IgA, IgG, and IgM antibodies is a highly sensitive and specific diagnostic assay for sporotrichosis.

    The current standard treatment for IgA nephropathy relies on steroid and/or immunosuppressive therapy and angiotensin converting enzyme inhibitors (ACEI) or angiotensin receptor blocker (ARB). This study examines the benefits and safety of combining valsartan with clopidogrel and leflunomide as a treatment for progressive IgA nephropathy. Patients with primary IgA nephropathy, confirmed by renal biopsy, were recruited for this study. Patients were separated into four groups (n = 42 each) after 2 months of run-in period of valsartan treatment. All patients were treated with valsartan alone (Group 1) or valsartan and either clopidogrel (Group 2) or leflunomide (Group 3) or both clopidogrel and leflunomide (Group 4). Each group was followed up for their next 24 months for 24 h urinary protein excretion, serum creatinine and estimated glomerular filtration rate (eGFR) to assess the effect of the treatment. Adverse effects were recorded concurrently to evaluate the safety of the treatment. Of all 168 patients, 107 were males and 61 were females, with an average age of 33.8 ± 8.79 years. Baseline characteristics were comparable among the four groups (P > 0.05) prior to the experimental treatment. There was a significant (P Valsartan combined with Clopidogrel and Leflunomide can reduce the urinary proteins loss and renal function deterioration for IgA nephropathy patients and cause minimal adverse reactions.

    Intravenous bisphosphonate therapy is the mainstay of medical treatment in osteogenesis imperfecta (OI) and has been shown to increase bone mass, decrease bone pain, improve mobility, and reduce the incidence of fractures. Sclerotic metaphyseal lines parallel to the growth plate are seen on long bone radiographs following cyclical intravenous therapy. These areas create stress risers within the bone that may act as foci for subsequent fractures as exemplified in this clinical case. An 8-year-old girl with OI sustained a distal radial fracture following 3 years of treatment with 6-monthly intravenous zoledronate. Her diagnosis, response to treatment, and subsequent fracture at a sclerotic metaphyseal line is described. Peripheral quantitative computer tomography was used to characterise the presence of multiple stress risers at the distal forearm. Trabecular bone mineral density fluctuated from 34 to 126% compared to neighbouring 2-mm regions. There remain many unanswered questions about optimal bisphosphonate treatment regimens in children with OI. The formation of stress risers following intravenous bisphosphonate treatment raises the hypothesis that a more frequent and low-dose bisphosphonate regimen would provide more uniform dosing of bone in the growing child and reduce the likelihood of fractures compared to current treatment practices.

    Several oral nonsteroidal anti-inflammatory drugs (NSAID) are effective to treat migraine attacks. Despite its efficacy to treat migraine and other pain, there are a few commercial NSAIDs available for intravenous (i.v.) administration. Lysine clonixinate (LC) is a NSAID derived from nicotinic acid that has been proven effective in various algic syndromes such as renal colic, nerve compression, muscular pain and odontalgias. The aim of this study was to evaluate the efficacy of the i.v. LC in the treatment of severe attacks of migraine. We studied prospectively 19 patients, 17 women and 2 men, ages from 18 to 57 years, with the diagnosis of migraine according to the International Headache Society criteria. The patients were oriented to proceed to the clinic once the headache has started, and were placed under an i.v. infusion of LC and saline in a superficial vein of the forearm, once the intensity reached severe. Evaluating the headache intensity after 30, 60 and 90 minutes, as well as the presence of side effects, we observed that all of the 19 patients were headache free after 90 minutes. Some patients presented mild adverse effects and the vital signs were not significantly affected. We then concluded that the i.v. infusion of the NSAID LC (2-3-chloro-o-toluidin)piridin-3-lysine carboxilate), a derived from the nicotinic acid with a chemical structure that resembles the flufenamic acid, was efficient abolishing a severe migraine attack after 90 minutes in 19 patients. Controlled studies with a double-blind and randomized design, and treating a greater number of patients and attacks are necessary to confirm these initial observations.

    Immunoglobulin (Ig)G4-associated cholangitis (IAC) is one of the common organ manifestations of IgG4-related systemic disease (ISD). IAC and autoimmune pancreatitis (AIP) may mimic sclerosing cholangitis, cholangiocarcinoma, or pancreatic carcinoma. Diagnosis is based on a combination of clinical, biochemical, radiological, and histological findings.To study the clinical presentation of and treatment strategy for IAC, we reviewed clinical, serologic, and imaging characteristics, as well as treatment response, in 39 patients with IAC. The majority of patients were men (82%). Clinical features on presentation included obstructive jaundice in 26 patients (67%) and abdominal pain in 20 (51%). Positive IgG4 immunostaining was seen in 27 patients. The median serum IgG4 level before treatment was 769.4 mg/dL (range, 309.1-1229.7 mg/dL). After the steroid therapy, the median serum IgG4 level in 23 patients was 247.0 mg/dL (range, 139.0-355.0 mg/dL). Cholangiograms were available in 36 (92%) patients. Stenosis of the lower part of the common bile duct was found in 26 of 39 patients. Stenosis was diffusely distributed in the intra- and extrahepatic bile ducts in 14 of 39 patients. Additionally, strictures of the bile duct were detected in the hilar hepatic lesions in 27 of 39 patients. AIP was the most frequent comorbidity (35/39 in this study) of IAC. Other affected organs included eyes (n = 6), salivary glands (sialadenitis, n = 10), lymph nodes (mediastinal and axillary, n = 3), kidneys (n = 2), and the retroperitoneum (retroperitoneal fibrosis, n = 2).Regarding treatment, 29 patients were treated with steroids, of whom one underwent pancreatoduodenectomy, and one underwent choledochojejunostomy. Eight patients were treated with biliary stents. The remaining 19 patients took prednisolone alone. Eight patients achieved spontaneous resolution. Four patients with suspected pancreatic cancer or cholangiocarcinoma underwent surgery, including 2

    Brief description of research area: A common problem in swine production is diarrhoea in newly weaned piglets, and huge quantities of antibiotics go to treat post-weaning diarrhoeas in piglets. The use of antibiotics can lead to the development of multi- and fully resistant bacteria, which...... consequently pose a great threat to human health. Therefore, sustainable alternatives for treating post-weaning diarrhoea without using antibiotics are in demand. Swine that are old (and big) enough for slaughter have during their upbringing been challenges by many different pathogens and thus have developed...... know: It is possible to multimerise immunoglobulins, which results in an advantage when binding to their respective antigens in comparison to the non-multimerised immunoglobulins, but too high degree of multimerisation abates immunoglobulin reactivity.

    Full Text Available P Brandon Bookstaver, April D Miller, Celeste N Rudisill, LeAnn B NorrisDepartment of Clinical Pharmacy and Outcomes Sciences, South Carolina College of Pharmacy, University of South Carolina Campus, Columbia, South Carolina, USAAbstract: This paper reviews the current data on the use of the first approved intravenous ibuprofen product for the management of post-operative pain and fever in the United States. The management of acute and post-operative pain and fever with nonsteroidal anti-inflammatory agents (NSAIDs is well documented. A search in Medline and International Pharmaceutical Abstracts of articles until the end of November 2009 and references of all citations were conducted. Available manufacturer data on file were also analyzed for this report. Several randomized controlled studies have demonstrated the opioid-sparing and analgesic effects of 400 and 800 mg doses of intravenous ibuprofen in a series of post-operative patient populations. Two recent studies have also noted the improvement in fever curves in critically ill and burn patients. These data, along with pharmacokinetic and pharmacologic properties, are explored in this review, which addresses the clinical utility of a parenteral NSAID in a hospitalized patient for post-operative pain management and fever reduction. Further data on intravenous ibuprofen are needed to define long-term utilization, management of acute pain, and use in special populations.Keywords: ibuprofen, intravenous, injectable, nonsteroidal anti-inflammatory drug

    This case report describes the possible benefit of intravenous lipid emulsion in two patients surviving a severe intoxication with hydroxychloroquine in a dose that was previously considered to be lethal. The first case involves a 25-year-old female who ingested 17.5 grams of hydroxychloroquine, approximately one hour before presentation. An ECG showed QRS widening and the lab results showed hypokalaemia. She became unconscious, and developed hypotension and eventually apnoea. After intubation, supportive care consisted of norepinephrine and supplementation of potassium. Moreover, sodium bicarbonate and intravenous lipid emulsion were started to prevent cardiac toxicity. After these interventions, haemodynamic stability was established within a few hours. Although cardiomyopathy was confirmed, the patient recovered after two weeks. The second case concerns a 25-year-old male who took 5 grams of hydroxychloroquine. At presentation, two hours after intake, he showed QTc prolongation and hypokalaemia. The patient was treated with the usual supportive care and, although presentation to hospital was later, with intravenous lipid emulsion. Also this patient recovered. In conclusion, these cases show the benefit of supplemental intravenous lipid emulsion to prevent cardiac toxicity after a severe intoxication with hydroxychloroquine.

    Bone and joint infection in adults arises most commonly as a complication of joint replacement surgery, fracture fixation and diabetic foot infection. The associated morbidity can be devastating to patients and costs the National Health Service an estimated £20,000 to £40,000 per patient. Current standard of care in most UK centres includes a prolonged course (4-6 weeks) of intravenous antibiotics supported, if available, by an outpatient parenteral antibiotic therapy service. Intravenous therapy carries with it substantial risks and inconvenience to patients, and the antibiotic-related costs are approximately ten times that of oral therapy. Despite this, there is no evidence to suggest that oral therapy results in inferior outcomes. We hypothesise that, by selecting oral agents with high bioavailability, good tissue penetration and activity against the known or likely pathogens, key outcomes in patients managed primarily with oral therapy are non-inferior to those in patients treated by intravenous therapy. The OVIVA trial is a parallel group, randomised (1:1), un-blinded, non-inferiority trial conducted in thirty hospitals across the UK. Eligible participants are adults (>18 years) with a clinical syndrome consistent with a bone, joint or metalware-associated infection who have received ≤7 days of intravenous antibiotic therapy from the date of definitive surgery (or the start of planned curative therapy in patients treated without surgical intervention). Participants are randomised to receive either oral or intravenous antibiotics, selected by a specialist infection physician, for the first 6 weeks of therapy. The primary outcome measure is definite treatment failure within one year of randomisation, as assessed by a blinded endpoint committee, according to pre-defined microbiological, histological and clinical criteria. Enrolling 1,050 subjects will provide 90 % power to demonstrate non-inferiority, defined as less than 7.5 % absolute increase in treatment

    Multiple sclerosis (MS) is an inflammatory and degenerative disease leading to demyelination and axonal damage in the CNS. Autoimmunity plays a central role in MS pathogenesis. Per definition, monoclonal antibodies are recombinant biological compounds with a well defined target, thus carrying the promise of targeting pathogenic cells or molecules with high specificity, avoiding undesired off-target effects. Natalizumab was the first monoclonal antibody to be approved for the treatment of MS. Several other monoclonal antibodies are in development and have demonstrated promising efficacy in phase II studies. They can be categorized according to their mode of action into compounds targeting (i) leukocyte migration into the CNS (natalizumab); (ii) cytolytic antibodies (rituximab, ocrelizumab, ofatumumab, alemtuzumab); or (iii) antibodies and recombinant proteins targeting cytokines and chemokines and their receptors (daclizumab, ustekinumab, atacicept, tabalumab [Ly-2127399], secukinumab [AIN457]). In this review, we discuss the specific molecular targets, clinical efficacy and safety of these compounds and discuss criteria to anticipate the position of monoclonal antibodies in the diversifying armamentarium of MS therapy in the coming years.

    To compare the efficacy of intravenous ondansetron or dexamethasone compared with intravenous fluid therapy alone in children presenting to the emergency department with refractory vomiting from viral gastritis who had failed attempts at oral hydration. This double-blind, randomized, controlled trial was performed in a tertiary care pediatric emergency department. Children aged 6 months to 12 years presenting with more than three episodes of vomiting in the past 24 hours, mild/moderate dehydration, and failed oral hydration were included. Patients with other medical causes were excluded. Subjects were randomized to dexamethasone 1 mg/kg (15 mg maximum), ondansetron 0.15 mg/kg, or placebo (normal saline [NS], 10 mL). All subjects also received intravenous NS at 10-20 mL/kg/hr. Oral fluid tolerance was evaluated at two and four hours. Those not tolerating oral fluids at four hours were admitted. Discharged patients were evaluated at 24 and 72 hours for vomiting and repeat health care visits. The primary study outcome was hospitalization rates between the groups. Data were analyzed using chi-square test, Kruskal-Wallis test, Mantel-Haenszel test, and analysis of variance, with p hydration than NS-treated patients (29 [67.4%]; relative risk, 1.28; 95% confidence interval = 1.02 to 1.68). There were no differences in number of mean episodes of vomiting or repeat visits to health care at 24 and 72 hours in the ondansetron, dexamethasone, or NS groups. In children with dehydration secondary to vomiting from acute viral gastritis, ondansetron with intravenous rehydration improves tolerance of oral fluids after two hours and reduces the hospital admission rate when compared with intravenous rehydration with or without dexamethasone.

  11. Clinical applications of immunoglobulin: update

    Directory of Open Access Journals (Sweden)

    Marcia Cristina Zago Novaretti

    2011-06-01

    Full Text Available Human immunoglobulin is the most used blood product in the clinical practice. Immunoglobulin applications have increased quickly since the elucidation of its immunomodulatory and antiinflammatory properties which turned this blood product into a precious tool in the treatment of numerous diseases that present with humoral immune deficiency or that cause immune system dysfunction. Currently, the approved indications for Ig are: primary immunodeficiencies, secondary immunodeficiencies (multiple myeloma or chronic lymphoid leukemia, Kawasaki syndrome, immune thrombocytopenic purpura, Guillain Barré syndrome, graft-versus-host disease following bone marrow transplantation and repeat infections in HIV children. On the other hand, there are numerous "off-label" indications of immunoglobulin, which represent 20-60% of all clinical applications of this drug. It is important to study all these indications and, above all, the scientific evidence for its use, in order to provide patients with a new therapeutic option without burdening the health system. This review results from a wide selection of papers identified in the Pubmed and Lilacs scientific electronic databases. A group of descriptors were used from human immunoglobulin to the names of each disease that immunoglobulin is clinically applied. Our main objective is to list the numerous indications of immunoglobulin, both authorized and "off-label" and to analyze these indications in the light of the most recent scientific evidence.

    Ischemic stroke is a major cause of disability and death in the USA. Intravenous tissue plasminogen activator (t-PA) remains underutilized. With the development of newer intra-arterial reperfusion therapies, there is increased opportunity to address the more devastating large-vessel occlusions. We seek to identify the numbers of patients with stroke treated with intravenous and intra-arterial therapies, as well as to estimate the potential number of intra-arterial cases in the foreseeable future. We performed a literature search to determine case volumes of intravenous t-PA use. We extrapolated the current case volume of intra-arterial stroke therapies from the numbers of cases in which the Merci retrieval device was used. In order to estimate the potential numbers of intra-arterial stroke cases, we characterized the percentage of patients with stroke who received intra-arterial therapy at two leading stroke centers. We applied these percentages to the numbers of patients with stroke seen at the top 100, 200 and 500 stroke centers by volume. The rate of intravenous t-PA use is 2.4-3.6%, resulting in 15 000-22 000 cases/year in the USA. The estimated case volume of intra-arterial therapies is 3500-7200 in 2006. Based on data from St. Luke's Brain and Stroke Institute and Massachusetts General Hospital, approximately 5-20% of patients with ischemic stroke can be treated with intra-arterial therapies. Extrapolating this to the top 500 stroke centers by volume, the potential number of intra-arterial cases in the USA is 10 400-41 500/year. Based on the current numbers of intra-arterial cases, our theoretical model identifies a potential for significant growth of this stroke therapy.

    PurposeExplore the application of endovascular covered stent-graft (SG) placement in femoral pseudoaneurysms in intravenous drug addicts.Materials and MethodsWe evaluated a consecutive series of pseudoaneurysm in intravenous drug addicts treated with SGs from August 2010 to December 2013.Results15 patients with 16 arterial pseudoaneurysms were enrolled in this study. All were males with a mean age of 36.9 years. Hemorrhage was the most common reason (93.8 %) for seeking medical care, and 3 of these patients were in hemorrhagic shock at admission. All patients received broad-spectrum antibiotics, and debridement and drainage were implemented after SG placement. 7 of the 13 cases which had microbiologic results showed mixed infections, while gram-negative bacteria were the major pathogens. Except for 2 patients, who were lost to follow-up, two new pseudoaneurysms formed due to delayed debridement, and one stent thrombosis occurred, none of the remaining cases had SG infection or developed claudication.ConclusionsSG placement controls massive hemorrhage rapidly, gives enough time for subsequent treatment for pseudoaneurysms due to intravenous drug abuse, and reduces the incidence of postoperative claudication. With appropriate broad-spectrum antibiotics and early debridement, the incidence of SG infection is relatively low. It is an effective alternative especially as temporary bridge measure for critical patients. However, the high cost, uncertain long-term prospects, high demand for medical adherence, and the risk of using the conduits for re-puncture call for a cautious selection of patients.

    5-Fluorouracil (5-Fu) is one of the most commonly prescribed antineoplastic agents against gastric and colorectal cancers. Continuous infusion would be the optimal way of its administration, however, may usually cause thrombosis, infection, and prolonged hospital stay. Oral fluoropyrimidines would be an attractive alternative, but their efficiency and toxicities for the treatment of gastric and colorectal cancer are still obscure as compared with infusion 5-Fu. Literature retrieval, trials selection and assessment, data collection, and statistic analysis were performed according to the Cochrane Handbook. The outcome measures were tumor response rate, progression-free survival, overall survival, and adverse effects. Twenty-nine randomized controlled trials, comprising totally 15 154 patients, were included. Meta-analysis showed similar overall outcome in terms of response rate (1.01; 95% confidence interval [CI], 0.92-1.12), progression-free survival (hazard ratio 1.00; 95%CI, 0.94-1.06), and overall survival (hazard ratio 0.96; 95%CI, 0.92-1.01) between oral fluoropyrimidine-based and intravenous 5-Fu-based regimens in gastric and colorectal cancer patients. The risk of grade 3/4 neutropenia, thrombocytopenia, and stomatitis was more prominent in intravenous 5-Fu-based regimens; while more frequent grade 3/4 hand-foot syndrome, diarrhea, and anorexia were detected in oral fluoropyrimidine-based regimens. Oral-fluoropyrimidines showed equivalent response and similar survival outcomes, but different toxicity profiles, as compared with intravenous 5-Fu. Thus, it would be a more convenient and adjustable alternative in treatment of advanced gastric and colorectal cancer. © 2017 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

    2016-08-01

    Rhizobium radiobacter, a soil-based organism, is not, usually, pathogenic unless in the immunecompromised. Endocarditis, in the immunocompromised, is a typical presentation generally as a result of catheter-based infections. We describe the presentation of R. radiobacter prosthetic valve endocarditis and the inherent challenges in its presentation and diagnosis. A patient presented with acute limb ischemia secondary to R. radiobacter-mediated endocarditis and subsequent thromboembolization of the distal superior femoral and proximal popliteal arteries in the left lower limb. He underwent an uneventful thrombolectomy that restored blood flow distal to the occlusion and restored the patency of the affected arteries. Postoperatively, the patient maintained several unexplained febrile episodes. Blood cultures remained negative for infection. A cardiac work-up demonstrated the presence of vegetative growth on the prosthetic mitral and native aortic valves. Histopathologic analysis of the extracted thrombus confirmed the presence of R. radiobacter. On further history, it was elucidated that the patient was an intravenous drug user who routinely stored drug paraphernalia in plant beds. The patient recovered uneventfully after Piptazobactam was administered. R. radiobacter, and similarly other soil-based pathogens, should be considered as a potential source of endocarditic infection and thromboembolization in patients who similarly describe a history of intravenous drug use.

    A 41-yr-old African elephant ( Loxodonta africana ) presented with a swollen third digit of the left forelimb and a 2-cm hole in the pad. Corrective trimming, topical treatments, and an oral antibiotic resulted in apparent resolution; however, it reoccurred after 4 mo. Radiographs suggested bone lysis in the third phalanx, with the primary differential diagnosis being septic osteitis. Flushing with metronidazole solution and intravenous regional perfusion (IVRP) of the foot were commenced. A tourniquet was applied just above the carpus, an interdigital vein was identified by ultrasound, and into this vein 2 g (20 ml) of ceftiofur sodium solution, followed by 60 ml of heparinized saline, was administered. The foot was kept raised for 25 min and then the tourniquet was removed. IVRP was repeated every other day for 70 treatments over 6 mo. Healing occurred, which was confirmed radiographically. IVRP offers an excellent treatment modality in a well-trained elephant.

    Full Text Available Intravenous glucocorticoids are recommended for multiple sclerosis (MS. However, they can be inconvenient and expensive. Due to their convenience and low cost, oral glucocorticoids may be an alternative treatment. Recently, several studies have shown that there is no difference in efficacy and safety between oral methylprednisolone (oMP and intravenous methylprednisolone (ivMP.We sought to assess the clinical efficacy, safety and tolerability of oral methylprednisolone versus intravenous methylprednisolone for MS relapses in this meta-analysis.Randomized controlled trials (RCTs evaluating the clinical efficacy, safety and tolerability of oral methylprednisolone versus intravenous methylprednisolone for MS relapses were searched in PubMed, Cochrane Library, Medline, EMBASE and China Biology Medicine until October 25, 2016, without language restrictions. The proportion of patients who had improved by day 28 was chosen as the efficacy outcome. We chose the risk ratio (RR to analyze each trial with the 95% confidence interval (95% CI. We also used the fixed-effects model (Mantel-Haenszel approach to calculate the pooled relative effect estimates.A total of 5 trials were identified, which included 369 patients. The results of our meta-analysis revealed that no significant difference existed in relapse improvement at day 28 between oMP and ivMP (RR 0.96, 95% CI 0.84 to 1.10. No evidence of heterogeneity existed among the trials (P = 0.45, I2 = 0%. Both treatments were equally safe and well tolerated except that insomnia was more likely to occur in the oMP group compared to the ivMP group.Our meta-analysis reveals strong evidence that oMP is not inferior to ivMP in increasing the proportion of patients experiencing clinical improvement at day 28. In addition, both routes of administration are equally well tolerated and safe. These findings suggest that we may be able to replace ivMP with oMP to treat MS relapses.

    AbstractBackgroundSevere malaria is a medical emergency with high mortality. Prompt achievement of therapeutic concentrations of highly effective anti-malarial drugs reduces the risk of death. The aim of this study was to assess the pharmacokinetics and pharmacodynamics of intravenous artesunate in Ugandan adults with severe malaria.MethodsFourteen adults with severe falciparum malaria requiring parenteral therapy were treated with 2.4 mg\\/kg intravenous artesunate. Blood samples were collected after the initial dose and plasma concentrations of artesunate and dihydroartemisinin measured by solid-phase extraction and liquid chromatography-tandem mass spectrometry. The study was approved by the Makerere University Faculty of Medicine Research and Ethics Committee (Ref2010-015) and Uganda National Council of Science and Technology (HS605) and registered with ClinicalTrials.gov (NCT01122134).ResultsAll study participants achieved prompt resolution of symptoms and complete parasite clearance with median (range) parasite clearance time of 17 (8–24) hours. Median (range) maximal artesunate concentration (Cmax) was 3260 (1020–164000) ng\\/mL, terminal elimination half-life (T1\\/2) was 0.25 (0.1-1.8) hours and total artesunate exposure (AUC) was 727 (290–111256) ng·h\\/mL. Median (range) dihydroartemisinin Cmax was 3140 (1670–9530) ng\\/mL, with Tmax of 0.14 (0.6 – 6.07) hours and T1\\/2 of 1.31 (0.8–2.8) hours. Dihydroartemisinin AUC was 3492 (2183–6338) ng·h\\/mL. None of the participants reported adverse events.ConclusionsPlasma concentrations of artesunate and dihydroartemisinin were achieved rapidly with rapid and complete symptom resolution and parasite clearance with no adverse events.

    In recent years, there has been increasing interest in the role of intravenous lipid formulations as potential antidotes in patients with severe cardiotoxicity caused by drug toxicity. The aim of this study was to conduct a comprehensive bibliometric analysis of all human and animal studies featuring lipid emulsion as an antidote for the treatment of acute poisoning. The Scopus database search was performed on 5 February 2016 to analyse the research output related to intravenous lipid emulsion as an antidote for the treatment of acute poisoning. Research indicators used for analysis included total number of articles, date (year) of publication, total citations, value of the h-index, document types, countries of publication, journal names, collaboration patterns and institutions. A total of 594 articles were retrieved from Scopus database for the period of 1955-2015. The percentage share of global intravenous lipid emulsion research output showed that research output was 85.86% in 2006-2015 with yearly average growth in this field of 51 articles per year. The USA, United Kingdom (UK), France, Canada, New Zealand, Germany, Australia, China, Turkey and Japan accounted for 449 (75.6%) of all the publications. The total number of citations for all documents was 9,333, with an average of 15.7 citations per document. The h-index of the retrieved documents for lipid emulsion research as antidote for the treatment of acute poisoning was 49. The USA and the UK achieved the highest h-indices, 34 and 14, respectively. New Zealand produced the greatest number of documents with international collaboration (51.9%) followed by Australia (50%) and Canada (41.4%) out of the total number of publications for each country. In summary, we found an increase in the number of publications in the field of lipid emulsion after 2006. The results of this study demonstrate that the majority of publications in the field of lipid emulsion were published by high-income countries. Researchers from

    Full Text Available Background: Propofol is one of the widely used intravenous (i.v. anaesthetics, although pain on injection still remains a considerable concern for the anaesthesiologists. A number of techniques has been tried to minimize propofol-induced pain with variable results. Recently, a 5-HT 3 antagonist, ondansetron pre-treatment, has been shown to reduce propofol-induced pain. The aim of our randomized, placebo-controlled, double-blinded study was to determine whether pre-treatment with intravenous granisetron, which is routinely used in our practice for prophylaxis of post-operative nausea and vomiting, would reduce propofol-induced pain. Methods: Eighty-two women, aged 18-50 years, American society of Anaesthesiologist grading (ASA I-II, scheduled for various surgeries under general anaesthesia were randomly assigned to one of the two groups. One group received 2 mL 0.9% sodium chloride while the other group received 2 mL granisetron (1 mg/mL, and were accompanied by manual venous occlusion for 1 min. Then, 2 mL propofol was injected through the same cannula. Patients were asked by a blinded investigator to score the pain on injection of propofol with a four-point scale: 0=no pain, 1=mild pain, 2=moderate pain, 3=severe pain. Results: Twenty-four patients (60% complained of pain in the group pre-treated with normal saline as compared with six (15% in the group pre-treated with granisetron. Pain was reduced significantly in the granisetron group (P<0.05. Severity of pain was also lesser in the granisetron group compared with the placebo group (2.5% vs. 37.5%. Conclusion: We conclude that pre-treatment with granisetron along with venous occlusion for 1 min for prevention of propofol-induced pain was highly successful.

    The treatment of patients with severe malaria in sub-Saharan Africa has become a challenge to clinicians due to poor compliance to quinine and the increasing multidrug resistance to antimalarials by the P. falciparum parasite. The aim of this study was to compare the efficacy and safety profile of two truncated antimalarial regimens of intravenous quinine followed by oral Malarone (Malarone arm) with intravenous quinine followed by oral quinine (quinine arm) in the treatment of severe P. falciparum malaria. The outcome measures were parasite clearance time, fever clearance time, efficacy, and adverse events profile. Consecutive patients aged 1-60 years, with a diagnosis of severe malaria with positive blood smears for P. falciparum parasites and admitted to the Moi Teaching and Referral Hospital were randomized into the two study arms. Of the 360 patients studied 167 and 193 cases were randomized into the Malarone and quinine arms, respectively. Of the five (1.4 per cent) patients who died, three came from the quinine arm. The frequency of adverse reactions was higher in the oral quinine group (31.6 per cent) than in the Malarone group (25.7 per cent). The mean parasite clearance time was 120 h and 108 h for the quinine and Malarone arms of the study, respectively, and the mean fever clearance times were 84 h and 72 h for the quinine and Malarone arms, respectively (p=0.1). Truncated therapeutic regimen using malarone after intravenous quinine is safer and as effective as conventional intravenous quinine followed by oral quinine in the treatment of severe malaria. The P. falciparum recrudescence rate was lower with the use of Malarone than for quinine.

  7. Home intravenous antibiotic treatment for acute pulmonary exacerbations in cystic fibrosis - Is it good for the patient?

    2009-01-01

    Full Text Available There is a worldwide drive for the home management of chronic respiratory diseases. With the widespread use of home intravenous (IV treatment for cystic fibrosis (CF pulmonary exacerbations (PExs, evidence pointing to an inferior outcome of care for home-treated patients in comparison to hospital-treated patients is a cause of concern. Currently, patients who self-administer IV antibiotics at home are provided with equipment and instructions on the use of antibiotics. Policies vary; but in most UK centers, these patients are then followed up by the multidisciplinary team only on days 1, 7 and 14 of the treatment course. We aimed to review the current published literature in search for evidence for the value and the shortfalls of self-administered IV treatment at home for acute PExs in CF patients in comparison to conventional hospital treatment. We searched the electronic database system Medline for published papers regarding studies comparing home- and hospital-based IV antibiotic treatment for both adult and pediatric CF patients. Sixteen studies were identified and grouped into those that showed a similar outcome between home and hospital treatment and those that showed an inferior outcome for home management. Most studies were retrospective or inadequately powered to provide clear answers. Ideally, outcome of care for home treatment should be at least equal to outcome for hospital treatment. Extensive efforts should be made to standardize therapies preserving the advantages of home management and addressing the perceived reasons for an inferior outcome. Until further studies provide definitive answers, treatment at home should be reserved for adequately selected patients and individualized depending on the unique settings of each CF center and specific patients′ requirements. There is great need for a prospective randomized controlled trial comparing home and hospital treatments in order to clarify this matter.

  8. Post-treatment haemolysis in severe imported malaria after intravenous artesunate: case report of three patients with hyperparasitaemia

    2012-05-01

    Full Text Available Abstract Parenteral artesunate has been shown to be a superior treatment option compared to parenteral quinine in adults and children with severe malaria. Little evidence, however, is available on long-term safety. Recently, cases of late-onset haemolysis after parenteral treatment with artesunate have been reported in European travellers with imported Plasmodium falciparum malaria. Therefore, an extended follow-up of adult patients treated for severe imported malaria was started in August 2011 at the University Medical Center Hamburg-Eppendorf. Until January 2012, three patients with hyperparasitaemia (range: 14-21% were included for analysis. In all three patients, delayed haemolysis was detected in the second week after the first dose of intravenous artesunate. Reticulocyte production index remained inadequately low in the 7 – 14 days following the first dose of artesunate despite rapid parasite clearance. Post-treatment haemolysis after parenteral artesunate may be of clinical relevance in particular in imported severe malaria characterized by high parasite levels. Extended follow-up of at least 30 days including controls of haematological parameters after artesunate treatment seems to be indicated. Further investigations are needed to assess frequency and pathophysiological background of this complication.

    Stimulation of vascular endothelial growth factor (VEGF) has been observed following transarterial chemoembolization (TACE) in hepatocellular cancer (HCC) and may contribute to tumor regrowth. This pilot study examined whether intravenous (IV) bevacizumab, a monoclonal antibody against VEGF, could inhibit neovessel formation after TACE. 30 subjects with HCC undergoing TACE at a single academic institution were randomized with a computer-generated allocation in a one to one ratio to either bevacizumab at a dose of 10 mg/kg IV every 14 days beginning 1 week prior to TACE (TACE-BEV arm) or observation (TACE-O arm). Angiography was performed with TACE at day 8, and again at weeks 10 and 14. Repeat TACE was performed at week 14 if indicated. TACE-BEV subjects were allowed to continue bevacizumab beyond week 16. TACE-O subjects were allowed to cross-over to bevacizumab at week 16 in the setting of progressive disease. The main outcome measure was a comparison of neovessel formation by serial angiography. Secondary outcome measures were progression free survival (PFS) at 16 weeks, overall survival (OS), bevacizumab safety, and an analysis of VEGF levels before and after TACE with and without bevacizumab. Among the 30 subjects enrolled, 9 of 15 randomized to the TACE-O arm and 14 of 15 randomized to the TACE-BEV arm completed all 3 angiograms. At week 14, 3 of 9 (33%) TACE-O subjects and 2 of 14 (14%) TACE-BEV subjects demonstrated neovascularity. The PFS at 16 weeks was 0.19 in the TACE-O arm and 0.79 in the TACE-BEV arm (p = 0.021). The median OS was 61 months in the TACE-O arm and 49 months in the TACE-BEV arm (p = 0.21). No life-threatening bevacizumab-related toxicities were observed. There were no substantial differences in bevacizumab pharmacokinetics compared to historical controls. Bevacizumab attenuated the increase in VEGF observed post-TACE. IV bevacizumab was well tolerated in selected HCC subjects undergoing TACE, and appeared to diminish neovessel formation

    Background. Mistletoe therapy (MT) is widely used in patient-centered integrative cancer care. The objective of this study was to explore the concepts, procedures, and observations of expert doctors, with a focus on intravenous MT. Method. A qualitative interview study was conducted with 35 highly experienced doctors specialized in integrative and anthroposophic medicine. Structured qualitative content analysis was applied. For triangulation, the results were compared with external evidence that was systematically collected, reviewed, and presented. Results. Doctors perform individualized patient assessments that lead to multimodal treatment approaches. The underlying goal is to help patients to live with and overcome disease. Mistletoe infusions are a means of accomplishing this goal. They are applied to stabilize disease, achieve responsiveness, induce fever, improve quality of life, and improve the tolerability of conventional cancer treatments. The doctors reported long-term disease stability and improvements in patients' general condition, vitality, strength, thermal comfort, appetite, sleep, pain from bone metastases, dyspnea in pulmonary lymphangitis carcinomatosa, fatigue, and cachexia; chemotherapy was better tolerated. Also patients' emotional and mental condition was reported to have improved. Conclusion. Individualized integrative cancer treatment including MT aims to help cancer patients to live well with their disease. Further research should investigate the reported observations.

    Nearly 10 years after its introduction into the market, the significance of lacosamide in genetic generalized epilepsies is still unclear. Its new mode of action may qualify lacosamide as a therapeutic agent in this entity, but only a limited number of cases have been published so far. To describe the efficacy of lacosamide as treatment in a patient with the absence status epilepticus. We report on a 28-year-old woman with genetic generalized epilepsy who suffered recurrent absence status epilepticus during video-EEG-monitoring. After treatment failure of first- and second-line medication, lacosamide was administered. The outcome in this patient was evaluated, and a systematic literature review was performed for the use of lacosamide in the absence status epilepticus. After application of 400 mg lacosamide intravenously, the absence status epilepticus terminated within 30 minutes. No further seizures or epileptiform discharges reoccurred until the end of video-EEG-Monitoring 3 days later. The role of lacosamide as a therapeutic option in patients with the absence status epilepticus is unclear. Only two cases have been reported so far with conflicting results. Further randomized controlled studies are required to validate the relevance of lacosamide as treatment for status epilepticus in genetic generalized and the absence epilepsy. © 2018 John Wiley & Sons A/S.

    Full Text Available Background. Mistletoe therapy (MT is widely used in patient-centered integrative cancer care. The objective of this study was to explore the concepts, procedures, and observations of expert doctors, with a focus on intravenous MT. Method. A qualitative interview study was conducted with 35 highly experienced doctors specialized in integrative and anthroposophic medicine. Structured qualitative content analysis was applied. For triangulation, the results were compared with external evidence that was systematically collected, reviewed, and presented. Results. Doctors perform individualized patient assessments that lead to multimodal treatment approaches. The underlying goal is to help patients to live with and overcome disease. Mistletoe infusions are a means of accomplishing this goal. They are applied to stabilize disease, achieve responsiveness, induce fever, improve quality of life, and improve the tolerability of conventional cancer treatments. The doctors reported long-term disease stability and improvements in patients’ general condition, vitality, strength, thermal comfort, appetite, sleep, pain from bone metastases, dyspnea in pulmonary lymphangitis carcinomatosa, fatigue, and cachexia; chemotherapy was better tolerated. Also patients’ emotional and mental condition was reported to have improved. Conclusion. Individualized integrative cancer treatment including MT aims to help cancer patients to live well with their disease. Further research should investigate the reported observations.

  13. Intermittent preventive sulfadoxine-pyrimethamine treatment of primigravidae reduces levels of plasma immunoglobulin G, which protects against pregnancy-associated Plasmodium falciparum malaria

    Pregnancy-associated malaria (PAM) is an important cause of maternal and neonatal suffering. It is caused by Plasmodium falciparum capable of inhabiting the placenta through expression of particular variant surface antigens (VSA) with affinity for proteoglycans such as chondroitin sulfate A....... Protective immunity to PAM develops following exposure to parasites inhabiting the placenta, and primigravidae are therefore particularly susceptible to PAM. The adverse consequences of PAM in primigravidae are preventable by intermittent preventive treatment (IPTp), where women are given antimalarials...... at specified intervals during pregnancy, but this may interfere with acquisition of protective PAM immunity. We found that Kenyan primigravidae receiving sulfadoxine-pyrimethamine IPTp had significantly lower levels of immunoglobulin G (IgG) with specificity for the type of parasite-encoded VSA-called VSA(PAM...

    Full Text Available Aluminium phosphide (AlP is used to protect stored grains from rodents. It produces phosphine gas (PH3, a mitochondrial poison thought to cause toxicity by blocking the cytochrome c oxidase enzyme and inhibiting oxidative phosphorylation, which results in cell death. AlP poisoning has a high mortality rate among humans due to the rapid onset of cardiogenic shock and metabolic acidosis, despite aggressive treatment. We report a 21-yearold male who was referred to the Afzalipour Hospital, Kerman, Iran, in 2015 after having intentionally ingested a 3 g AlP tablet. He was successfully treated with crystalloid fluids, vasopressors, sodium bicarbonate, digoxin, glucagon and antioxidant agents and was discharged from the hospital six days after admission in good clinical condition. For the treatment of AlP poisoning, the combination of glucagon and digoxin with antioxidant agents should be considered. However, evaluation of further cases is necessary to optimise treatment protocols.

    BACKGROUND: The efficacy of α1 proteinase inhibitor (A1PI) augmentation treatment for α1 antitrypsin deficiency has not been substantiated by a randomised, placebo-controlled trial. CT-measured lung density is a more sensitive measure of disease progression in α1 antitrypsin deficiency emphysema...... of emphysema, a finding that could not be substantiated by lung density measurement at FRC alone or by the two measurements combined. These findings should prompt consideration of augmentation treatment to preserve lung parenchyma in individuals with emphysema secondary to severe α1 antitrypsin deficiency...

    Patients with intractable rheumatoid arthritis (RA) were treated with total lymphoid irradiation (TLI, 200 rad). The authors previously reported long-lasting clinical improvement in this group associated with a persistent decrease in circulating Leu-3 (helper subset) T cells and marked impairment of in vitro lymphocyte function. In the present experiments, they studied the mechanisms underlying the decrease in pokeweed mitogen stimulated immunoglobulin (Ig) secretion observed after TLI. Peripheral blood mononuclear cells (PBL) from TLI-treated patients produced 10-fold less Ig (both IgM and IgG) in response to pokeweed mitogen than before radiotherapy. This decrease in Ig production was associated with the presence of suppressor cells in co-culture studies. By using responder cells obtained from normal individuals (allogeneic system), PBL from eight of 12 patients after TLI suppressed Ig synthesis by more than 50%. In contrast, PBL from the same patients before TLI failed to suppress Ig synthesis. PBL with suppressive activity contained suppressor T cells, and the latter cells bore the Leu-2 surface antigen. In 50% of the patients studied suppressor cells were also found in the non-T fraction and were adherent to plastic. Interestingly, the Leu-2 + cells from TLI-treated patients were no more potent on a cell per cell basis than purified Leu-2 + cells obtained before TLI. Additional experiments suggested that the suppression mediated by T cells after TLI is related to the increased ratio of Leu-2 to Leu-3 cells observed after radiotherapy

    There are no randomized trials comparing intravenous iron to RBC transfusion for the treatment of severe postpartum anaemia. The objectives of this study were to evaluate the feasibility of randomizing women with severe postpartum anaemia secondary to postpartum haemorrhage to RBC transfusion or intravenous iron, and to describe patient-reported outcomes, and haematological and iron parameters. Women with a postpartum haemorrhage exceeding 1000 ml and an Hb between 5·6 and 8·1 g/dl were randomized to 1500 mg of intravenous iron (n = 7) isomaltoside or RBC transfusion (n = 6). Participants completed the Multidimensional Fatigue Inventory and Edinburgh Postnatal Depression Scale, and blood samples were drawn at inclusion, daily during the first week and at weeks 3, 8 and 12. We screened 162 women and included 13 (8%). There was no significant difference between groups in fatigue or depression scores. RBC transfusion was associated with a higher Hb on day 1, inhibition of reticulocytosis during the first week and low iron levels. Intravenous iron was associated with increased reticulocytosis during the first week, repleted iron stores and a higher Hb in weeks 3-12. This pilot study shows that intravenous iron could be an attractive alternative to RBC transfusion in severe postpartum anaemia, and that a larger trial is needed and feasible. © 2016 The Authors.

  1. Bleeding risk during treatment of acute thrombotic events with subcutaneous LMWH compared to intravenous unfractionated heparin; a systematic review.

    Directory of Open Access Journals (Sweden)

    Giorgio Costantino

    Full Text Available BACKGROUND: Low Molecular Weight Heparins (LMWH are at least as effective antithrombotic drugs as Unfractionated Heparin (UFH. However, it is still unclear whether the safety profiles of LMWH and UFH differ. We performed a systematic review to compare the bleeding risk of fixed dose subcutaneous LMWH and adjusted dose UFH for treatment of venous thromboembolism (VTE or acute coronary syndromes (ACS. Major bleeding was the primary end point. METHODS: Electronic databases (MEDLINE, EMBASE, and the Cochrane Library were searched up to May 2010 with no language restrictions. Randomized controlled trials in which subcutaneous LMWH were compared to intravenous UFH for the treatment of acute thrombotic events were selected. Two reviewers independently screened studies and extracted data on study design, study quality, incidence of major bleeding, patients' characteristics, type, dose and number of daily administrations of LMWH, co-treatments, study end points and efficacy outcome. Pooled odds ratios (OR and 95% confidence intervals (CI were calculated using the random effects model. RESULTS: Twenty-seven studies were included. A total of 14,002 patients received UFH and 14,635 patients LMWH. Overall, no difference in major bleeding was observed between LMWH patients and UFH (OR = 0.79, 95% CI 0.60-1.04. In patients with VTE LMWH appeared safer than UFH, (OR = 0.68, 95% CI 0.47-1.00. CONCLUSION: The results of our systematic review suggest that the use of LMWH in the treatment of VTE might be associated with a reduction in major bleeding compared with UFH. The choice of which heparin to use to minimize bleeding risk must be based on the single patient, taking into account the bleeding profile of different heparins in different settings.

    Full Text Available Objective: There are few published reports concerning the efficacy of oral ibuprofen for the treatment of patent ductus arteriosus (PDA in extremely low birth weight (ELBW infants. Oral ibuprofen was compared to intravenous indomethacin regarding efficacy and safety in the treatment of PDA in infants weighting less than 1,000 g at birth. Method: This was a retrospective study in a single center. Data on ELBW infants who had an echocardiographically confirmed PDA were collected. The infants were treated with either intravenous indomethacin or oral ibuprofen. Rate of ductal closure, need for additional treatment, drug-related side effects or complications, and mortality were compared between the two treatment groups. Result: 26 infants who received indomethacin and 22 infants who received ibuprofen were studied. The overall rate of ductal closure was similar between the two treatments: it occurred in 23 of 26 infants (88.5% treated with indomethacin, and in 18 of 22 infants (81.8% treated with ibuprofen (p = 0.40. The rate of surgical ligation (11.5% versus 18.2%; p = 0.40 did not differ significantly between the two treatment groups. No significant difference was found in post-treatment serum creatinine concentrations between the two groups. There were no significant differences regarding additional side effects or complications. Conclusion: In ELBW infants, oral ibuprofen is as efficacious as intravenous indomethacin for the treatment of PDA. There were no differences between the two drugs with respect to safety. Oral ibuprofen could be used as an alternative agent for the treatment of PDA in ELBW infants. Resumo: Objetivo: Existem poucos relatórios publicados com relação à eficácia do ibuprofeno via oral no tratamento da persistência do canal arterial (PCA em neonatos com extremo baixo peso ao nascer (EBPN.

    Pooled human immunoglobulins (IGs) are prepared from plasma obtained from healthy donors as a concentrated antibody-containing solution. In addition, high-titer IGs (hyperimmune) against a specific pathogen can be obtained from vaccinated or convalescing donors. Currently, IGs can be used for the treatment of a variety of infections for which no specific therapy exists or that remain difficult to treat. Moreover, the recent pathogen outbreaks for which there is no approved treatment have renewed attention to the role of convalescent plasma and IGs. Areas covered: In this review, a historical perspective of the use of sera and IGs in humans as anti-infective agents (any viral, bacterial, parasitic infection), excluding immunodeficient patients, is presented from early development to the latest clinical studies. A Medline search was conducted to examine the peer-reviewed literature, with no date limits. Expert commentary: Human pooled plasma-derived IG products benefit from the polyclonal response of every individual donor and from the interindividual variability in such response. The trend to increased availability of vaccines for infectious diseases also opens new potential applications of hyperimmune IGs for emerging or re-emerging infectious diseases (e.g.: Ebola, Zika, Dengue), for the prevention and treatment in the general population, healthcare personnel and caregivers.

Puerperal anemia can impair postpartum maternal and neonatal well-being. Objective: To determine the effect of treatment of moderate puerperal iron-deficiency anemia using a single intravenous total-dose iron dextran versus daily single dose oral iron(III-hydroxide polymaltose. Methodology: A randomized controlled study in which postpartum women with moderate iron-deficiency anemia were randomized into treatment with either a single total-dose intravenous iron dextran or with daily single doses of oral iron(III-hydroxide polymaltose tablets for 6 weeks. Effects on hemoglobin concentration using either method were compared at 6 weeks postpartum. Analysis was per protocol using SPSS version 17 for windows. P-values ≤0.05 were considered significant. Results: Two hundred eighty-four women were recruited for the study: 142 women received single total dose intravenous infusion of iron dextran while 142 received daily oral iron(III-hydroxide polymaltose tablets. Approximately 84.0% (237/282 completed the study and were analyzed including 81% (115/142 of those randomized to injectable iron therapy compared to 85.9% (122/142 of those randomized to oral treatment.

    Exchange transfusion and phototherapy have traditionally been used to treat jaundice and avoid the associated neurological complications. Because of the risks and burdens of exchange transfusion, intravenous immunoglobulin (IVIg) has been suggested as an alternative therapy for alloimmune hemolytic disease of the newborn (HDN) to reduce the need for exchange transfusion. To assess the effect and complications of IVIg in newborn infants with alloimmune HDN on the need for and number of exchange transfusions. We performed electronic searches of CENTRAL, PubMed, Embase (Ovid), Web of Science, CINAHL (EBSCOhost), Academic Search Premier, and the trial registers ClinicalTrials.gov and controlled-trials.com in May 2017. We also searched reference lists of included and excluded trials and relevant reviews for further relevant studies. We considered all randomized and quasi-randomized controlled trials of IVIg in the treatment of alloimmune HDN. Trials must have used predefined criteria for the use of IVIg and exchange transfusion therapy to be included. We used the standard methods of Cochrane and its Neonatal Review Group. We assessed studies for inclusion and two review authors independently assessed quality and extracted data. We discussed any differences of opinion to reach consensus. We contacted investigators for additional or missing information. We calculated risk ratio (RR), risk difference (RD) and number needed to treat for an additional beneficial outcome (NNTB) for categorical outcomes. We calculated mean difference (MD) for continuous variables. We used GRADE criteria to assess the risk of bias for major outcomes and to summarize the level of evidence. Nine studies with 658 infants fulfilled the inclusion criteria. Term and preterm infants with Rh or ABO (or both) incompatibility were included. The use of exchange transfusion decreased significantly in the immunoglobulin treated group (typical RR 0.35, 95% CI 0.25 to 0.49; typical RD -0.22, 95% CI -0.27 to

    Intravenous bisphosphonate therapy is the first-line treatment in moderate-to-severe osteogenesis imperfecta (OI), but there are varied treatment protocols with little data on long-term efficacy. This study evaluates the clinical outcomes when transitioning from active bisphosphonate treatment to maintenance therapy. A retrospective review was conducted on 17 patients before treatment, following active treatment (zoledronate 0.05 mg/kg 6-monthly or pamidronate 6-9 mg/kg/year) and after establishment on maintenance treatment for more than 2 years (zoledronate 0.025 mg/kg 6-monthly or pamidronate lean tissue mass increased during active treatment. These improvements were maintained during the period of maintenance treatment. Vertebral height improved in fractured thoracic vertebrae from pre-treatment to active therapy and improved further during maintenance treatment. Metacarpal cortical thickness and relative cortical area also increased over the treatment periods. Maintenance intravenous bisphosphonate therapy preserved the beneficial effects of active treatment at the doses stated above. Further studies are required to determine the optimal bisphosphonate treatment regimen in the management of children with OI. © 2015 S. Karger AG, Basel.

    Postoperative nausea and vomiting (PONV) remains the most common postoperative complication, and causes decreased patient satisfaction, prolonged postoperative hospital stays, and unanticipated admission. There are limited data that indicate that dextrose may reduce nausea and vomiting. In this trial, we attempted to determine whether the rate of PONV can be decreased by postoperative administration of IV dextrose bolus. To test the effect of postoperative dextrose administration on PONV rates, we conducted a double-blind, randomized, placebo-controlled trial. We enrolled 62 nondiabetic, ASA class I or II nonsmoking outpatients scheduled for gynecologic laparoscopic and hysteroscopic procedures. Patients were randomized into 2 groups: the treatment group received dextrose 5% in Ringer lactate solution, and the control (placebo) group received Ringer lactate solution given immediately after surgery. All patients underwent a standardized general anesthesia and received 1 dose of antiemetic a half hour before emergence from anesthesia. PONV scores, antiemetic rescue medications, narcotic consumption, and discharge time were recorded in the postanesthesia care unit (PACU) in half-hour intervals. The 2 groups were similar with regard to age, weight, anxiety scores, prior PONV, non per os status, presurgical glucose, anesthetic duration, intraoperative narcotic use, and total weight-based fluid volume received. Postoperative nausea scores were not significantly different in the dextrose group compared with the control group (P > 0.05) after Bonferroni correction for repeated measurements over time. However, patients who received dextrose 5% in Ringer lactate solution consumed less rescue antiemetic medications (ratio mean difference, 0.56; 95% confidence interval, 0.39-0.82; P = 0.02), and had a shorter length of stay in the PACU (ratio mean difference, 0.80; 95% confidence interval, 0.66-0.97; P = 0.03) compared with patients in the control group.

    Haemodynamically significant patent ductus arteriosus is a significant cause of morbidity and mortality in pre-term infants. This retrospective study was conducted to investigate the usefulness of lower-dose paracetamol for the treatment of patent ductus arteriosus in pre-term infants. A total of 13 pre-term infants who received intravenous paracetamol because of contrindications or side effects to oral ibuprofen were retrospectively enrolled. In the first patient, the dose regimen was 15 mg/kg/dose, every 6 hours. As the patient developed significant elevation in transaminase levels, the dose was decreased to 10 mg/kg/dose, every 8 hours in the following 12 patients. Echocardiographic examination was conducted daily. In case of closure, it was repeated after 2 days and when needed thereafter in terms of reopening. A total of 13 patients received intravenous paracetamol. Median gestational age was 29 weeks ranging from 24 to 31 weeks and birth weight was 950 g ranging from 470 to 1390 g. The median postnatal age at the first intravenous paracetamol dose was 3 days ranging from 2 to 9 days. In 10 of the 13 patients (76.9%), patent ductus arteriosus was closed at the median 2nd day of intravenous paracetamol ranging from 1 to 4 days. When the patient who developed hepatotoxicity was eliminated, the closure rate was found to be 83.3% (10/12). Intravenous paracetamol may be a useful treatment option for the treatment of patent ductus arteriosus in pre-term infants with contrindication to ibuprofen. In our experience, lower-dose paracetamol is effective in closing the patent ductus arteriosus in 83.3% of the cases.

    In patients with ischemic heart disease and arrhythmias, selection of antiarrhythmic treatment is often difficult as it is hard to separate "primary" from ischemic arrhythmias. We studied 20 patients with ischemic heart disease, who developed ventricular arrhythmias consistently during exercise test. Exercise test was performed twice during infusion of placebo and then during intravenous administration of nitroglycerin, titrated to reduce systolic blood pressure by 10 mmHg. Exercise duration was 7.8 +/- 1.7 and 7.9 +/- 1.5 min, in the 2 placebo tests (NS). Angina developed in 5 patients and ischemic ST changes in 10. With nitroglycerin exercise duration increased to 8.4 +/- 20 min (p less than 0.05), diagnostic ST segment depression was observed in 2 patients and only 1 had angina. In all 20 patients, ventricular arrhythmias were consistently present during both tests on placebo, that were markedly reduced by nitroglycerin. In fact, ventricular ectopic beats were 455 (mean 35.8 +/- 16.8) and 418 (mean 34.4 +/- 11.1) in the 2 exercise tests with placebo, and 11 during nitroglycerin infusion (mean 0.6 +/- 0.1; p less than 0.001). Couplets were 28 and 29 during placebo (NS) and 0 during nitroglycerin (p less than 0.001). Ventricular tachycardia was present in 6 and 8 patients during placebo but in none during nitroglycerin (p less than 0.001). Reduction of exercise-induced arrhythmias was maintained during chronic treatment with oral vasodilators. Prevention of exercise-related arrhythmias by nitroglycerin infusion appears a good indicator of their ischemic origin and may provide valuable information for long-term profilaxis with oral vasodilators, then avoiding the use of antiarrhythmic agents and their potential side effects.

    Full Text Available INTRODUCTION: This study aimed to discuss the results of the intravenous thrombolytic treatment (IV-tPA to acute ischemic stroke patients, in the light of the literature. METHODS: We performed our study with forty acute ischemic stroke patients who were receiving the IV-tPA in the intensive care unit of our neurology clinic between 2011 and 2015.. The demographic, clinical and radiological data were collected retrospectively. The intracranial hemorrhage detected within 3 months after discharge and neurological status at the end of the 3rd month were evaluated by using modified Rankin scale (MRS and National Institutes of Health Stroke Scale (NIHSS scores. The symptom-to-needle time, Alberta stroke programe early computed tomography score (ASPECT and initial and follow-up scores of NIHSS were analyzed. RESULTS: Fifteen patients were female, twenty-five were male, and the mean age was 66.45±10.56. The initial mean NIHSS score was 13±4.33, whereas it was 4,10±3,37at 3rd month. The initial mean ASPECT score was 8.23±1.20. Symptomatic intracranial hemorrhage was detected in 1 patient and asymptomatic intracranial hemorrhage was detected in 6. The mean symptom-to-needle time was 139,0±48,1 minutes. The neurological disability of 13 patients ( %32.5 were fully recovered at the end of the 3rd month, while 7 patients were died. (% 17,5 The initial NIHSS and ASPECT scores were significantly different between group of patients with a MRS score between 0-2 and between 3-6 (p=0.03 and p=0.006; respectively, while the symptom-to-needle time was not different (p=0.79. DISCUSSION AND CONCLUSION: The results of the current study are in accordance with previous studies in the literature. These results have shown that the IV-tPA treatment is efficient and safe treatment modality in acute ischemic stroke, and reduces disability at the end of the 3rd month.

    Full Text Available Non-steroidal anti-inflammatory drugs are often used as components of multimodal therapy for postoperative pain management, but their use is currently limited by its side effects. The specific objective of this study was to evaluate the efficacy and safety of a new formulation of intravenous (IV ibuprofen for the management of postoperative pain in a European population.A total of 206 patients from both abdominal and orthopedic surgery, were randomly assigned in 1:1 ratio to receive 800 mg IV-ibuprofen or placebo every 6 hours; all patients had morphine access through a patient controlled analgesia pump. The primary outcome measure was median morphine consumption within the first 24 hours following surgery. The mean±SEM of morphine requirements was reduced from 29,8±5,25 mg to 14,22±3,23 mg (p = 0,015 and resulted in a decrease in pain at rest (p = 0,02 measured by Visual Analog Scale (VAS from mean±SEM 3.34±0,35 to 0.86±0.24, and also in pain during movement (p = 0,02 from 4.32±0,36 to 1.90±0,30 in the ibuprofen treatment arm; while in the placebo group VAS score at rest ranged from 4.68±0,40 to 2.12±0,42 and during movement from 5.66±0,42 to 3.38±0,44. Similar treatment-emergent adverse events occurred across both study groups and there was no difference in the overall incidence of these events.Perioperative administration of IV-Ibuprofen 800 mg every 6 hours in abdominal surgery patient's decreases morphine requirements and pain score. Furthermore IV-Ibuprofen was safe and well tolerate. Consequently we consider appropriate that protocols for management of postoperative pain include IV-Ibuprofen 800 mg every 6 hours as an option to offer patients an analgesic benefit while reducing the potentially risks associated with morphine consumption.EU Clinical Trials Register 2011-005007-33.

    Myasthenia gravis is an autoimmune neuromuscular disorder. There are several treatment options, including symptomatic treatment (acetylcholinesterase inhibitors), short-term immunosuppression (corticosteroids), long-term immunosuppression (azathioprine, cyclosporine, cyclophosphamide, methotrexate, mycophenolate mofetil, rituximab, tacrolimus), rapid acting short-term immunomodulation (intravenous immunoglobulin, plasma exchange), and long-term immunomodulation (thymectomy). This review explores in detail these different treatment options. Potential future treatments are also discussed. PMID:21845054

    Henoch-Schönlein purpura is an immunoglobulin A-mediated, small vascular inflammatory disease that can be associated with palpable purpura, arthralgia, abdominal pain, or nephritis. The presence of purpura facilitates the diagnosis of Henoch-Schönlein purpura at the onset of associated symptoms, whereas the absence of purpura makes the diagnosis challenging. It is important to diagnose Henoch-Schönlein purpura with delayed-onset skin purpura to avoid unnecessary surgery for acute abdomen. Most cases of Henoch-Schönlein purpura with severe abdominal pain are treated with low-dose steroids and intravenous immunoglobulin. A 15-year-old Korean girl complained of severe abdominal pain and delayed-onset purpura on admission. Henoch-Schönlein purpura was diagnosed based on endoscopic findings of hemorrhagic duodenitis and duodenal vasculitis and abdominal computed tomography findings of edematous bowels. Two common initial treatments, a low-dose steroid and intravenous immunoglobulin, were administered, but there was no improvement for 1 month. Subsequently, we used high-dose intravenous methylprednisolone pulse therapy (30 mg/kg/day, with a maximum of 1g/day), which dramatically alleviated her abdominal symptoms. High-dose intravenous methylprednisolone pulse therapy can be used as the ultimate treatment for delayed-onset Henoch-Schönlein purpura with severe abdominal pain when symptoms do not improve after low-dose steroid and intravenous immunoglobulin treatments.

    Full Text Available Abstract Background Taurolidine (TRD is a novel agent with multimodal antineoplastic effects. We present the case of a tumor remission after intravenous administration of taurolidine in a patient with gastric cancer re-recurrence. Case presentation A 58 years old male patient suffering from a gastric adenocarcinoma was submitted to partial gastrectomy and partial liver resection (pT2, pN1, pM1L (liver segment 2, N0, V0. 24 months later a local recurrence was diagnosed and the patient was reoperated. Postoperatively the patient underwent a palliative chemotherapy with eloxatin, FU, and leucovorin. A subsequent CT-revealed a liver metastasis and a recurrence adjacent to the hepatic artery. After successful radiofrequency ablation of the liver metastasis the patient was intravenously treated with 2% taurolidine. The patient endured the therapy well and no toxicity was observed. CT-scans revealed a stable disease without a tumor progression or metastatic spread. After 39 cycles the patient was submitted to left nephrectomy due to primary urothelial carcinoma and died 2 days later due to myocardial infarction. Postmortem histology of the esophageal-jejunal anastomosis and liver revealed complete remission of the known metastasized gastric adenocarcinoma. Conclusion The intravenous treatment with 2% taurolidine led to a histological remission of the tumor growth without any toxicity for the patient.

    Recent evidence has suggested that intra-arterial thrombolysis may provide benefit beyond intravenous thrombolysis in ischemic stroke patients. Previous meta-analyses have only compared intra-arterial thrombolysis with standard treatment without thrombolysis. The objective was to review the benefits and harms of intra-arterial thrombolysis in ischemic stroke patients. We undertook a meta-analysis of randomized controlled trials comparing the efficacy and safety of intra-arterial thrombolysis with either standard treatment or intravenous thrombolysis following acute ischemic stroke. Primary outcomes included poor functional outcomes (modified Rankin Scale 3-6), mortality, and symptomatic intracranial hemorrhage. Study quality was assessed, and outcomes were stratified by comparison treatment received. Four trials (n = 351) comparing intra-arterial thrombolysis with standard treatment were identified. Intra-arterial thrombolysis reduced the risk of poor functional outcomes (modified Rankin Scale 3-6) [relative risk (RR) = 0·80; 95% confidence interval = 0·67-0·95; P = 0·01]. Mortality was not increased (RR = 0·82; 95% confidence interval = 0·56-1·21; P = 0·32); however, risk of symptomatic intracranial hemorrhage was nearly four times more likely (RR = 3·90; 95% confidence interval = 1·41-10·76; P = 0·006). Two trials (n = 81) comparing intra-arterial thrombolysis with intravenous thrombolysis were identified. Intra-arterial thrombolysis was not found to reduce poor functional outcomes (modified Rankin Scale 3-6) (RR = 0·68; 95% confidence interval = 0·46-1·00; P = 0·05). Mortality was not increased (RR = 1·12; 95% confidence interval = 0·47-2·68; P = 0·79); neither was symptomatic intracranial hemorrhage (RR = 1·13; 95% confidence interval = 0·32-3·99; P = 0·85). Differences in time from symptom onset-to-treatment and type of thrombolytic administered were found

    We previously showed that 40 % of clinically stable patients hospitalised for community-acquired pneumonia (CAP) are not switched to oral therapy in a timely fashion because of physicians' barriers. We aimed to decrease this proportion by implementing a novel protocol. In a multi-centre controlled before-and-after study, we evaluated the effect of an implementation strategy tailored to previously identified barriers to an early switch. In three Dutch hospitals, a protocol dictating a timely switch strategy was implemented using educational sessions, pocket reminders and active involvement of nursing staff. Primary outcomes were the proportion of patients switched timely and the duration of intravenous antibiotic therapy. Length of hospital stay (LOS), patient outcome, education effects 6 months after implementation and implementation costs were secondary outcomes. Statistical analysis was performed using mixed-effects models. Prior to implementation, 146 patients were included and, after implementation, 213 patients were included. The case mix was comparable. The implementation did not change the proportion of patients switched on time (66 %). The median duration of intravenous antibiotic administration decreased from 4 days [interquartile range (IQR) 2-5] to 3 days (IQR 2-4), a decrease of 21 % [95 % confidence interval (CI) 11 %; 30 %) in the multi-variable analysis. LOS and patient outcome were comparable before and after implementation. Forty-three percent (56/129) of physicians attended the educational sessions. After 6 months, 24 % (10/42) of the interviewed attendees remembered the protocol's main message. Cumulative implementation costs were 5,798 (20/reduced intravenous treatment day). An implementation strategy tailored to previously identified barriers reduced the duration of intravenous antibiotic administration in hospitalised CAP patients by 1 day, at minimal cost.

    Full Text Available OBJECTIVE: Intravenous iron is widely used to treat iron deficiency in day-care units. Ferric carboxymaltose (FCM allows administration of larger iron doses than iron sucrose (IS in each infusion (1000 mg vs. 200 mg. As FCM reduces the number of infusions required but is more expensive, we performed a cost-minimization analysis to compare the cost impact of the two drugs. MATERIALS AND METHODS: The number of infusions and the iron dose of 111 consecutive patients who received intravenous iron at a gastrointestinal diseases day-care unit from 8/2007 to 7/2008 were retrospectively obtained. Costs of intravenous iron drugs were obtained from the Spanish regulatory agencies. The accounting department of the Hospital determined hospital direct and indirect costs for outpatient iron infusion. Non-hospital direct costs were calculated on the basis of patient interviews. In the pharmacoeconomic model, base case mean costs per patient were calculated for administering 1000 mg of iron per infusion using FCM or 200 mg using IS. Sensitivity analysis and Monte Carlo simulation were performed. RESULTS: Under baseline assumptions, the estimated cost of iron infusion per patient and year was €304 for IS and €274 for FCM, a difference of €30 in favour of FCM. Adding non-hospital direct costs to the model increased the difference to €67 (€354 for IS vs. €287 for FCM. A Monte Carlo simulation taking into account non-hospital direct costs favoured the use of FCM in 97% of simulations. CONCLUSION: In this pharmacoeconomic analysis, FCM infusion reduced the costs of iron infusion at a gastrointestinal day-care unit.

    Hydroxocobalamin is a Food and Drug Administration-approved antidote for cyanide poisoning. Cobinamide is a potential antidote that contains 2 cyanide-binding sites. To our knowledge, no study has directly compared hydroxocobalamin with cobinamide in a severe, cyanide-toxic large-animal model. Our objective is to compare the time to return of spontaneous breathing in swine with acute cyanide-induced apnea treated with intravenous hydroxocobalamin, intravenous cobinamide, or saline solution (control). Thirty-three swine (45 to 55 kg) were intubated, anesthetized, and instrumented (continuous mean arterial pressure and cardiac output monitoring). Anesthesia was adjusted to allow spontaneous breathing with FiO2 of 21% during the experiment. Cyanide was continuously infused intravenously until apnea occurred and lasted for 1 minute (time zero). Animals were then randomly assigned to receive intravenous hydroxocobalamin (65 mg/kg), cobinamide (12.5 mg/kg), or saline solution and monitored for 60 minutes. A sample size of 11 animals per group was selected according to obtaining a power of 80%, an α of .05, and an SD of 0.17 in mean time to detect a 20% difference in time to spontaneous breathing. We assessed differences in time to death among groups, using Kaplan-Meier estimation methods, and compared serum lactate, blood pH, cardiac output, mean arterial pressure, respiratory rate, and minute ventilation time curves with repeated-measures ANOVA. Baseline weights and vital signs were similar among groups. The time to apnea and cyanide dose required to achieve apnea were similar. At time zero, mean cyanide blood and lactate concentrations and reduction in mean arterial pressure from baseline were similar. In the saline solution group, 2 of 11 animals survived compared with 10 of 11 in the hydroxocobalamin and cobinamide groups (Pcyanide concentrations became undetectable at the end of the study in both antidote-treated groups, and no statistically significant differences

    Describe the treatment of patients with vaso-occlusive crises (VOC) in a Brazilian emergency department (ED) and the successful switch from intravenous to oral morphine. We analyzed records of 315 patients with sickle cell disease using two different protocols for pain: one in March 2010 prescribing intravenous morphine every 4 h throughout their stay, and another in March 2011 and 2012 prescribing one initial dose of intravenous morphine followed by equianalgesic doses of oral morphine every 4 h. Patients were triaged into three groups: mild, moderate, and severe VOC. The mild group was treated within 1 h after triage, the moderate within 30 min and the severe was treated immediately. Patients whose pain was not relieved within 6 h after the first dose of morphine were transferred into a different holding area of the ED where they continued to receive the same treatment for 48 h after which they were hospitalized if still in pain. The number of patients who stayed <24 h in the ED increased significantly from 63 in 2010 to 87 in 2012, and the number of admissions decreased from 26 in 2010 to 10 in 2012. The incidence of acute chest syndrome decreased from 8.5% in 2010 to 1.9% in 2012. Patients treated with oral morphine stayed a shorter time in the ED, had more pain relief, were admitted less frequently, and had less acute chest syndrome. These differences may be due to environmental, cultural, psychological, and pharmacogenetic factors. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Patients treated with intravenous zoledronic acid 5 mg for osteoporosis may experience post-dose influenza-like symptoms. Oral acetaminophen/paracetamol or ibuprofen administered 4 h post-infusion reduced the proportion of patients with increased oral temperature and worsening post-infusion symptom scores vs. placebo, thus providing an effective strategy for the treatment of such symptoms. Once-yearly intravenous zoledronic acid 5 mg is a safe and effective treatment for postmenopausal osteoporosis. This study assessed whether transient influenza-like post-dose symptoms associated with intravenous infusion of zoledronic acid can be reduced by post-dose administration of acetaminophen/paracetamol or ibuprofen. In an international, multicenter, randomized, double-blind, double-dummy parallel-group study, bisphosphonate-naïve postmenopausal women with osteopenia (n = 481) were randomized to receive zoledronic acid 5 mg + acetaminophen/paracetamol (n = 135), ibuprofen (n = 137) or placebo (n = 137), or placebo + placebo (n = 72). Acetaminophen/paracetamol and ibuprofen were administered every 6 h for 3 days beginning 4 h post-infusion. The proportion of patients with increased oral temperature (≥1°C above 37.5°C) and with worsening post-infusion symptom scores over 3 days was significantly lower in patients receiving ibuprofen (36.8% and 48.5%) or acetaminophen/paracetamol (37.3% and 46.3%) vs. those receiving placebo (63.5% and 75.9%, respectively; all p paracetamol or ibuprofen. Oral acetaminophen/paracetamol or ibuprofen effectively managed the transient influenza-like symptoms associated with zoledronic acid 5 mg.

    Aldosterone prevents the uptake of norepinephrine in the myocardium. Atrial natriuretic peptide (ANP), a circulating hormone of cardiac origin, inhibits aldosterone synthase gene expression in cultured cardiocytes. We evaluated the effects of intravenous ANP on cardiac sympathetic nerve activity (CSNA) and aldosterone suppression in patients with acute decompensated heart failure (ADHF). We studied 182 patients with moderate nonischemic ADHF requiring hospitalization and treated with standard therapy containing intravenous ANP and 10 age-matched normal control subjects. ANP was continuously infused for >96 h. In all subjects, delayed total defect score (TDS), heart to mediastinum ratio, and washout rate were determined by 123 I-metaiodobenzylguanidine (MIBG) scintigraphy. Left ventricular (LV) end-diastolic volume, end-systolic volume, and ejection fraction were determined by echocardiography. All patients with acute heart failure (AHF) were examined once within 3 days and then 4 weeks after admission, while the control subjects were examined only once (when their hemodynamics were normal). Moreover, for 62 AHF patients, plasma aldosterone concentrations were measured at admission and 1 h before stopping ANP infusion. 123 I-MIBG scintigraphic and echocardiographic parameters in normal subjects were more favorable than those in patients with AHF (all p < 0.001). After treatment, all these parameters improved significantly in AHF patients (all p < 0.001). We also found significant correlation between percent changes of TDS and aldosterone concentrations (r = 0.539, p < 0.001) in 62 AHF patients. The CSNA and LV performance were all improved in AHF patients. Furthermore, norepinephrine uptake of myocardium may be ameliorated by suppressing aldosterone production after standard treatment containing intravenous ANP. (orig.)

    Sjogren's syndrome, involving sicca symptoms with xerostomia, stomatitis, and considerable pain is a difficult-to-treat autoimmune disease where the treatment options are limited and, as in the case of methotrexate, have a low therapeutic index. This case report concerns a male patient, aged 75 years and vegetarian, with Sjogren's syndrome subsequently confirmed by salivary gland biopsy. Serum antinuclear antibodies (ANA) were elevated (1 : 320). Low serum vitamin B12 and iron levels could be improved after 20 days using vitamin B12 and iron oral supplements. Despite symptomatic treatment, xerostomia, glossitis, and glossodynia were still present, at times marked, after 12 months when the ANA titer was unchanged. Following treatment with an anti-inflammatory polyvalent immunoglobulin formulation (Lactobin®N, 7 g daily), a bovine colostrum concentrate given orally in combination with oral vitamin D3 (2,000 IU daily), sicca symptoms and xerostomia progressively decreased and at day 750 were confined to occasional and minor glossitis of the upper lip. This case report demonstrates the satisfactory control of Sjogren's syndrome using oral polyvalent immunoglobulins with vitamin D3. In contrast to treatment options involving antimalarial drugs and methotrexate, there are no safety issues in patients tolerant to milk products.

    Objectives To assess the effect of thoracic paravertebral block (PVB) on pain management and preservation of pulmonary function compared with intravenous, patient-controlled analgesia (IVPCA) in patients with multiple rib fractures (MRFs). Methods Ninety patients with unilateral MRFs were included in this prospective study and randomly assigned to the TPVB or IVPCA group. The visual analogue scale (VAS) pain score, blood gas analysis, and bedside spirometry were measured and recorded at different time points after analgesia. Results TPVB and IVPCA provided good pain relief. VAS scores were significantly lower in the TPVB group than in the IVPCA group at rest and during coughing ( P pain relief and preservation of pulmonary function in patients with MRFs.

    A 7-year-old male English Coonhound with suspected myxedema coma complicated by severe hypothermia and metabolic abnormalities was treated with a combination of active external and core rewarming techniques, i.v. and oral administration of levothyroxine, supplemental oxygen, and administration of fluids (0.9% NaCl solution). Myxedema coma develops as a consequence of severe hypothyroidism and is characterized by a hypometabolic, stuporous state. Myxedema coma is associated with a high mortality rate, and most reported cases have involved Doberman Pinschers. Intravenous administration of levothyroxine can be used successfully in combination with oral administration to restore normal metabolic function and assist in warming and thermoregulation, although dosages should be conservative to avoid adverse cardiovascular effects.

    Intravenous (iv) administration of an antidepressant is a common practice in some European countries, particularly in France, Spain, and Italy in the initial treatment phase of hospitalised, severe depressed patients. After a beneficial response is observed, patients are switched to an oral formulation. The approved treatment period of the iv form of citalopram is limited to 8-10 days. The high bioavailability of citalopram permits the use of identical iv and oral doses. Citalopram is a racemate, consisting of a 1:1 mixture of the S- and R-enantiomers. The therapeutically active component is the S-enantiomer (escitalopram). Pharmacokinetic single dose administration studies in healthy subjects have demonstrated that daily oral administration of 20 mg of escitalopram or 40 mg citalopram results in similar plasma concentrations of the S-enantiomer of citalopram. This open-label multicentre French prospective study investigated the tolerability and efficacy of oral escitalopram 10 and 20 mg/day, administered for a 6-week period as continuation treatment of citalopram (20 mg or 40 mg daily) intravenous (iv), in patients with Major Depressive Disorder. A total of 171 patients were enrolled, of whom 147 (85%) completed the study. The mean MADRS score at inclusion (last citalopram dose) was 31.6 +/- 9.9. The total MADRS score decreased after 3 days of oral treatment with escitalopram. Escitalopram demonstrated a continuous effect in treating depressive symptoms throughout the study. The decrease in MADRS mean total score from baseline was statistically significant to each visit (day 3, 15; p or = 50%), and the majority of them were considered remitters (final MADRS score escitalopram was well tolerated in the study population. In all, 57 patients (33%) reported at least one adverse event (AE) during the study (21 patients in the 10 mg group and 36 patients in the 20 mg group); of these, 7 patients (4%) withdrew from the study. The most frequently reported AEs were

    Purpose: To test the hypothesis that daily intravenous pre-hydration decreases renal toxicity and improves chemotherapy adherence in patients receiving daily cisplatin to concurrent radiotherapy for locally advanced non-small cell lung cancer (NSCLC). Patients and methods: Patients with locally advanced NSCLC were treated between 2008 and August 2012 with daily 6 mg/m 2 cisplatin as a bolus injection in 10 ml; of saline and 66 Gy/24 fr radiotherapy in 32 days. Since January 2011, the administration of cisplatin was routinely preceded by intravenous pre-hydration with 1 L of natriumchloride 0.9%. Patients were divided in a pre-hydrated (PH) and non-pre-hydrated (NPH) cohort. Serum-creatinine and glomerular filtration rate (GFR) were assessed twice weekly during treatment. Retrospectively, baseline data, toxicity, treatment adherence and efficacy data were compared. Results: Of the 356 patients 232 NPH patients and 100 PH patients were eligible. Patient-and treatment characteristics compared equally. The median of the maximum decrease in GFR was 24% and 8% for NPH and PH (p < 0.01), respectively. Sixty-nine percent of the patients in the NPH group completed the 24 administrations of cisplatin, as compared to 83% of the PH group (p < 0.01). Nineteen percent vs. 2% of the patients in the NPH and PH group discontinued cisplatin treatment because of renal toxicity. Surprisingly, the incidence of acute esophageal toxicity grade ⩾2 decreased following prehydration: 62% vs. 34% (p < 0.001) for the NPH and PH groups, respectively. The one-year survival was comparable between groups (75% for NPH and 71% for PH). Conclusion: Daily pre-hydration was associated with a reduced rate of both renal and acute esophageal toxicity and an increased chemotherapy adherence in patients receiving daily dose of cisplatin and concurrent radiotherapy for locally advanced NSCLC

    Full Text Available Acute headaches are responsible for a significant percentage of the case load at primary care units and emergency rooms in Brazil. Dipyrone (metamizol is easily available in these settings, being the most frequently used drug. We conducted a randomized, placebo-controlled, double-blind study to assess the effect of dipyrone in the acute treatment of episodic tension-type headache. Sixty patients were randomized to receive placebo (intravenous injection of 10 ml saline or 1 g dipyrone in 10 ml saline. We used seven parameters of analgesic evaluation. The patients receiving dipyrone showed a statistically significant improvement (P<0.05 of pain compared to placebo up to 30 min after drug administration. The therapeutic gain was 30% in 30 min and 40% in 60 min. The number of patients needed to be treated for at least one to have benefit was 3.3 in 30 min and 2.2 in 60 min. There were statistically significant reductions in the recurrence (dipyrone = 25%, placebo = 50% and use of rescue medication (dipyrone = 20%, placebo = 47.6% for the dipyrone group. Intravenous dipyrone is an effective drug for the relief of pain in tension-type headache and its use is justified in the emergency room setting.

    The aim of this study was to develop PEGylated phosphatidylcholine (PC)-rich nanovesicles (phosphatiosomes) carrying ciprofloxacin (CIPX) for lung targeting to eradicate extracellular and intracellular methicillin-resistant Staphylococcus aureus (MRSA). Soyaethyl morphonium ethosulfate (SME) was intercalated in the nanovesicle surface with the dual goals of achieving strengthened bactericidal activity of CIPX-loaded phosphatiosomes and delivery to the lungs. The isothermal titration calorimetry (ITC) results proved the strong association of SME phosphatiosomes with pulmonary surfactant. We demonstrated a superior anti-MRSA activity of SME phosphatiosomes compared to plain phosphatiosomes and to free CIPX. A synergistic effect of CIPX and SME nanocarriers was found in the biofilm eradication. SME phosphatiosomes were readily engulfed by the macrophages, restricting the intracellular MRSA count by 1-2 log units. SME phosphatiosomes efficiently accumulated in the lungs after intravenous injection. In a rat model of lung infection, the MRSA burden in the lungs could be decreased by 8-fold after SME nanosystem application. Copyright © 2017 Elsevier Inc. All rights reserved.

    Little is known about the anti-tumor activity of humoral immunity in lung cancer patients treated with nivolumab, an immune checkpoint inhibitor. Herein, we report a case of lung cancer with 5% expression of PD-L1, in which a partial response to nivolumab was sustained for > 7 months. Immunohistochemical analysis of the metastatic lymph node biopsy specimen showed prominent accumulation of plasma cells and immunoglobulin G. These findings suggest that pre-existing humoral immunity may be worth considering as a candidate therapeutic biomarker of nivolumab in some lung cancer patients. © 2018 The Authors.

    Full Text Available Neurological disorders are among the main clinical problems affecting preterm children and often result in the development of communication and learning disabilities later in life. Several factors are of importance for brain development, however the role of immunoglobulins (passive immunity transfer has not yet been investigated. Piglets are born agammaglobulinemic, as a result of the lack of transfer of maternal immunoglobulins in utero, thus, they serve as an ideal model to mimic the condition of immunoglobulin deficiency in preterm infants. Thirty six, unsuckled newborn piglets were fed an infant formula or colostrum and supplemented orally or intravenously with either species-specific or foreign immunoglobulin and then compared to both newborn and sow-reared piglets. Two days after the piglets were born behavioural tests (novel recognition and olfactory discrimination of conspecifics scent were performed, after which the piglets were sacrificed and blood, cerebrospinal fluid and hippocampi samples were collected for analyses. Both parameters of neuronal plasticity (neuronal maturation and synapse-associated proteins and behavioural test parameters appeared to be improved by the appearance of species-specific porcine immunoglulin in the circulation and cerebrospinal fluid of the piglets. In conclusion, we postulate possible positive clinical effects following intravenous infusion of human immunoglobulin in terms of neuronal plasticity and cognitive function in preterm infants born with low blood immunoglobulin levels.

    Full Text Available Intravenous levodopa has been used in a multitude of research studies due to its more predictable pharmacokinetics compared to the oral form, which is used frequently as a treatment for Parkinson’s disease (PD. Levodopa is the precursor for dopamine, and intravenous dopamine would strongly affect vascular tone, but peripheral decarboxylase inhibitors are intended to block such effects. Pulse and blood pressure, with orthostatic changes, were recorded before and after intravenous levodopa or placebo—after oral carbidopa—in 13 adults with a chronic tic disorder and 16 tic-free adult control subjects. Levodopa caused no statistically or clinically significant changes in blood pressure or pulse. These data add to previous data that support the safety of i.v. levodopa when given with adequate peripheral inhibition of DOPA decarboxylase.

    Substance use disorders (SUD) are inheritable and the culprit is hypodopaminergic function regulated by reward genes. We evaluated a natural dopaminergic agonist; KB220 intravenous (IV) and oral variants, to improve dopaminergic function in SUD. Our pilot experiment found a significant reduction of chronic symptoms, measured by the Chronic Abstinence Symptom Severity (CASS) Scale. The combined group (IV and oral) did significantly better than the oral-only group over the first week and 30-day follow-up period. Next, the combination was given to129 subjects and three factors; Emotion, Somatic, and Impaired Cognition, with eigenvalues greater than one were extracted for baseline CASS-Revised (CASS-R) variables. Paired sample t-tests for pre and post-treatment scales showed significant declines (p = .00001) from pre- to post-treatment: t = 19.1 for Emotion, t = 16.1 for Somatic, and t = 14.9 for Impaired Cognition. In a two-year follow-up of 23 subjects who underwent KB220IV therapy (at least five IV treatments over seven days) plus orals for 30+ days: 21 (91%) were sober at six months, 19 (82%) having no relapse; 19 (82%) were sober at one year, 18 (78%) having no relapse; and 21 (91%) were sober two-years post-treatment, 16 (70%) having no relapse. We await additional research and advise caution in interpreting these encouraging results. PMID:23457891

  4. Intra-arterial and intra-venous chemotherapy combined with radiation in the treatment of brain tumours

    The present investigations were undertaken to study the effect of combining different modalities of chemotherapy with radiation in post-operative treatment of brain tumours. The conclusions and clinical implication of the investigations are as follows: The combination of combined intra-arterial chemotherapy followed by radiation leads to an increased median survival with more long term survivors in patients with anaplastic astrocytomas and in patients older than 40 years with astrocytomas. In patients with glioblastoma multiforme, this modality of treatment do not improve median survival, but an increased number of long-term survivors may be seen. Patients younger than 40 years with astrocytomas do not benefit from this modality of treatment. A parallelism exists between sensitivity to chemotherapy and response to radiotherapy. Patients who will benefit from the treatment may be selected early, normally two months after treatment start. Combining intra-arterial chemotherapy and radiation does not lead to an increased incidence of adverse CNS reactions. Specific transient abnormalities in the brain may occur during the first year after treatment and may be misinterpreted as tumour recurrence. EEG may be valuable in predicting adverse CNS reactions following treatment. Nuclear brain scan may be of valuable in selecting the patients who are in danger of developing adverse CNS reactions. Intra-arterial chemotherapy does have an effect in patients with brain tumours who have recurrent tumour after radiation. The most important prognostic factors are age, corticosteroid dependency at treatment start, performance status, histology and frontal lobe location. 103 refs., 2 tabs

    accumulating in support of calreticulin as a polypeptide binding chaperone. In contrast to mammalian immunoglobulin G (IgG), which has complex type N-glycans, chicken immunoglobulin Y (IgY) possesses a monoglucosylated high mannose N-linked glycan, which is a ligand for calreticulin. Here, we have used solid...... and solution-phase assays to analyze the in vitro binding of calreticulin, purified from human placenta, to human IgG and chicken IgY in order to compare the interactions. In addition, peptides from the respective immunoglobulins were included to further probe the binding specificity of calreticulin....... The experiments demonstrate the ability of calreticulin to bind to denatured forms of both IgG and IgY regardless of the glycosylation state of the proteins. Furthermore, calreticulin exhibits binding to peptides (glycosylated and non-glycosylated) derived from trypsin digestion of both immunoglobulins...

    Iron deficiency is the leading cause of anemia in patients with inflammatory bowel disease (IBD). Intravenous iron is the first-line treatment for clinically active IBD or previous oral iron intolerance. The aim of the present study was to develop a comparative model of iron deficiency and delivery for iron isomaltoside (IIM), ferric carboxymaltose (FCM), low molecular weight iron dextran (LMWID), and iron sucrose (IS) in the treatment of iron deficiency anemia associated with IBD. Areas covered: A model was developed to evaluate iron delivery characteristics, resource use and costs associated with IIM, FCM, LMWID and IS. Iron deficiency was modeled using dosing tables and retreatments were modeled based on a pooled retrospective analysis. The analyses were conducted over 5 years in patients with IBD with mean bodyweight of 75.4 kg and hemoglobin levels of 10.77 g/dL based on observational data. Expert opinion: The modeling analysis showed that using IIM required 1.2 infusions (per treatment) to correct the mean iron deficit, compared with 1.6, 1.2, and 7.1 with FCM, LMWID and IS, respectively. Costs were estimated to be 2,518 pounds sterling (GBP) per patient with IIM or LMWID, relative to GBP 3,309 with FCM or GBP 14,382 with IS.

    We performed a preliminary feasibility and safety study using intravenous (IV) administration of a platelet glycoprotein IIb/IIIa inhibitor (abciximab) in conjunction with intraarterial (IA) administration of a thrombolytic agent (reteplase) in a primate model of intracranial thrombosis. We introduced thrombus through superselective catheterization of the intracranial segment of the internal carotid artery in 16 primates. The animals were randomly assigned to receive IA reteplase and IV abciximab (n =4), IA reteplase and IV placebo (n =4), IA placebo and IV abciximab (n =4) or IA and IV placebo (n =4). Recanalization was assessed by serial angiography during the 6-h period after initiation of treatment. Postmortem magnetic resonance (MR) imaging was performed to determine the presence of cerebral infarction or intracranial hemorrhage. Partial or complete recanalization at 6 h after initiation of treatment (decrease of two or more points in pre-treatment angiographic occlusion grade) was observed in two animals treated with IA reteplase and IV abciximab, three animals treated with IA reteplase alone and one animal treated with IV abciximab alone. No improvement in perfusion was observed in animals that received IV and IA placebo. Cerebral infarction was demonstrated on postmortem MR imaging in three animals that received IA and IV placebo and in one animal each from the groups that received IA reteplase and IV abciximab or IV abciximab alone. One animal that received IV abciximab alone had a small intracerebral hemorrhage on MR imaging. (orig.)

    To compare the short term clinical and biological effects of intravenous (i.v.) pulse methylprednisolone (MP) and infliximab (IFX) in patients with severe active rheumatoid arthritis (RA) despite methotrexate (MTX) treatment. Patients with active RA despite MTX treatment were randomly allocated to receive a single i.v. infusion of MP (1 g) or three i.v. infusions of IFX (3 mg/kg) on weeks 0, 2, and 6. Patients were "blindly" evaluated for disease activity measures. Quality of life (QoL) was evaluated through the SF-36 health survey. Serum matrix metalloproteinase-3 (MMP-3) titres were measured at baseline, weeks 2 and 6. Compared with baseline, significant improvement was noted in all activity measures, including serum C reactive protein (CRP) titres, in the IFX group only. At week 14, 6/9 (67%) and 4/9 (44%) IFX patients met the ACR20 and 50 response criteria, while this was the case in only 1/12 (8%) and 0/12 (0%) MP patients, respectively (ptreatment, whereas some did so in the IFX group. Serum MMP-3 titres significantly decreased (41% drop) at week 6 in the IFX group, while no changes were seen in patients given MP. This short term randomised comparative study demonstrates that TNF blockade is better than MP pulse therapy in a subset of patients with severe refractory RA, with improvement in not only clinical parameters of disease activity but also biological inflammatory indices, such as serum CRP and MMP-3 titres.

    Patients who suffer re-infarction during initial hospitalization for ST-elevation myocardial infarction (STEMI) have decreased survival compared to patients without re-infarction, so treatment of re-infarction may influence survival. To determine whether the utilization of reperfusion therapies varied within 12 h of re-infarction and was associated with 30-day mortality, we studied 552 patients with re-infarction of 17,073 patients with STEMI enrolled in HERO-2 in five regions (Russia, Eastern Europe, Western Countries, Asia, and Latin America). Patients presenting within 6 h of symptom-onset were randomized to receive either bivalirudin or unfractionated heparin intravenously just prior to streptokinase. Re-infarction occurred in 2.8 and 3.6% of bivalirudin and heparin treated patients, respectively (P = 0.004), but treatment assignment did not influence mortality after re-infarction. Patients with re-infarction had a higher 30-day mortality than those without re-infarction (24 vs. 10%; P model). Within 12 h of re-infarction, fibrinolytic therapy was administered to 12.0 and 8.2% underwent percutaneous coronary intervention (PCI); these two treatments were more frequently utilized in patients from Western countries (n = 112), compared to patients from other countries (n = 440) (34.8 and 16.1% compared to 6.1 and 6.1%, respectively, P < 0.001). Mortality was 15% in patients receiving reperfusion therapy for re-infarction and 27% for those with conservative management, hazard ratio (HR) 0.53 (95% CI 0.32-0.88), P = 0.01. In multiple Cox regression analysis which included adjustment for clinical variables and randomized treatment assignment, 30-day mortality after re-infarction varied by region (highest Latin America 29%, lowest Western countries 15%; P = 0.01). Other independent prognostic factors included age, time from randomization to re-infarction, and Killip class at randomization. The HR for PCI treatment of re-infarction was 0.18 [(95% CI 0.04-0.76), P = 0

    Full Text Available Postoperative pain is the most important factor od so called "tumor promotive effect of surgery" ie. of endocrine-metabolic changes having the consequence drop in immune, antiinfective and antitumor defense. Due to presence of organic involutive changes, old people (≥ 65 years, often have serious side effects during application of usual analgetics. Since hypertonic glucose (33% given i.v. or per os, works analgesically in small children there is assumption that it can be used in treatment of postoperative pain in old oncology patients. We tested the hypothesis that postoperative pain in old oncology patients can be treated with i.v. application of 50% of glucose solution. 37 oncology patients over 65 years, 26 females and 11 males, operated for breast cancer and soft tissue cancer, werw investigated. Average age of the patients was 72±4 years. 50% Glucose solution was given in two boluses of 20 ml each: the first bolus was given to all patients at the end of anesthesia and the other bolus was given individually after appearance of post-operative pain. Pain intensity (in coefficients of the visual analogue scale VAK = 1-100 and its characteristics were tested by oral testing of operated patients: after weaking from anesthesia, after the first appearance of the pain and 15 minutes after giving of the second glucose bolus. None patient had pain weaking from anesthesia. All tested patients experienced pain during the first 70 minutes and it could be categorized as very strong pain (=82 VAK. The pain was decreased with another glucose bolus by approximately (=56% VAK so it was classifies in category of bearable pains (=36 VAK. In 9 patients (24,3% the pain had neuropatic component (filing of "burning" which could not be eliminated by hypertonic glucose but only with application of tramadol. Activation of the central cholinergic transmission is the most significant mechanism of analgesic glucose effect, but, probably there is another one

    Full Text Available Background and Aims: A retrospective analysis of treatment outcome using recommended dose of sodium stibogluconate (SSG alone and in combination with other antileishmanial drugs in adults with post-kala-azar dermal leishmaniasis (PKDL attending as outpatients. Methods: A total of 61 patients seen over ten years were included in the report. All had polymorphic lesions. Diagnosis was based on clinical picture, hailing from kala-azar (KA endemic area, exclusion of other dermatoses, histopathology, and therapeutic response. Patients were distributed into two groups: Group I (n = 32, where SSG was given intravenously; in Group II (n = 29, they were allocated to one of four categories using SSG in combination with other drugs. In the first category, SSG was given along with allopurinol (n = 10; in second with rifampicin (n = 6; and in third with both allopurinol and rifampicin (n = 5. In the fourth category, SSG was administered with an immunomodulator (n = 8, Mw vaccine, known to enhance host Th1 response. Results: Only 12 out of 61 patients completed treatment till histopathologic evidence of cure, five in Group I and seven in Group II, no patient being from third category. None had taken SSG without interruptions. Time taken for papulonodules to subside was similar in both groups, but erythema and induration subsided earlier in Group II. Group I patients attained cure after 120 injections while in Group II it took 95 injections in SSG + allopurinol and Mw vaccine categories respectively, and 110 with SSG + rifampicin. Nevertheless this was insufficient to facilitate compliance. Poor performance and high dropouts related to long duration of therapy, thrombophlebitis, difficulty in accessing veins, disabling rheumatic side-effects and practical problems. Liver, renal and pancreatic functions and ECG remained normal. Conclusion: No major advantage was obtained using allopurinol, rifampicin or Mw vaccine along with SSG as compared to SSG alone.

    A subcutaneous (SC) formulation of rituximab (MabThera ® /Rituxan ® ) has been developed that could reduce administration time and improve patient satisfaction with treatment. The Rituximab Administration Satisfaction Questionnaire (RASQ) was created to assess patients' perceptions and satisfaction with rituximab SC (RASQ-SC) or rituximab intravenous (RASQ-IV). We assessed the content validity and psychometric properties of RASQ in patients with non-Hodgkin lymphoma. Face and content validity of RASQ-SC and RASQ-IV were qualitatively assessed using 60-minute combined concept elicitation and cognitive debriefing interviews. Psychometric validation of RASQ (item performance and reliability) was assessed quantitatively against the established Cancer Therapy Satisfaction Questionnaire (CTSQ), using questionnaire data from the PrefMab (NCT01724021) and MabCute (NCT01461928) clinical studies. RASQ-IV demonstrated excellent coverage of concepts relevant to patients' (n=10) own treatment experiences and no new concepts were identified. Patients' expectations of rituximab SC were conceptually consistent with items included in the RASQ-SC, suggesting that the tool is also conceptually adequate. In 1,051 patients from PrefMab and MabCute, correlations with domains such as "RASQ: Physical Impacts" and "CTSQ: Feelings About Side Effects", "RASQ: Physical Impacts" and "CTSQ: Satisfaction With Therapy", and "RASQ: Satisfaction" and "CTSQ: Satisfaction With Therapy", achieved moderate-to-high correlations (>0.4) for convergent domains and <0.3 for divergent domains. This study supports the qualitative face and content validity and psychometric validity of RASQ-IV and RASQ-SC. Minor revisions were made to the questionnaires to enhance clarity and aid consistent reporting.

    Intrauterine infection with Ureaplasma spp. is strongly associated with preterm birth and adverse neonatal outcomes. We assessed whether combined intraamniotic (IA) and maternal intravenous (IV) treatment with one of two candidate antibiotics, azithromycin (AZ) or solithromycin (SOLI), would eradicate intrauterine Ureaplasma parvum infection in a sheep model of pregnancy. Sheep with singleton pregnancies received an IA injection of U. parvum serovar 3 at 85 days of gestational age (GA). At 120 days of GA, animals (n=5 to 8/group) received one of the following treatments: (i) maternal IV SOLI with a single IA injection of vehicle (IV SOLI only); (ii) maternal IV SOLI with a single IA injection of SOLI (IV+IA SOLI); (iii) maternal IV AZ and a single IA injection of vehicle (IV AZ only); (iv) maternal IV AZ and a single IA injection of AZ (IV+IA AZ); or (v) maternal IV and single IA injection of vehicle (control). Lambs were surgically delivered at 125 days of GA. Treatment efficacies were assessed by U. parvum culture, quantitative PCR, enzyme-linked immunosorbent assay, and histopathology. Amniotic fluid (AF) from all control animals contained culturable U. parvum. AF, lung, and chorioamnion from all AZ- or SOLI-treated animals (IV only or IV plus IA) were negative for culturable U. parvum. Relative to the results for the control, the levels of expression of interleukin 1β (IL-1β), IL-6, IL-8, and monocyte chemoattractant protein 2 (MCP-2) in fetal skin were significantly decreased in the IV SOLI-only group, the MCP-1 protein concentration in the amniotic fluid was significantly increased in the IV+IA SOLI group, and there was no significant difference in the histological inflammation scoring of lung or chorioamnion among the five groups. In the present study, treatment with either AZ or SOLI (IV only or IV+IA) effectively eradicated macrolide-sensitive U. parvum from the AF. There was no discernible difference in antibiotic therapy efficacy between IV-only and IV

    Intravenous thrombolysis is an effective emergency treatment for acute ischaemic stroke for patients meeting specific criteria. Approximately 12% of eligible patients in England, Wales and Northern Ireland received thrombolysis in the first quarter of 2013, yet as many as 15% are eligible to receive treatment. Suboptimal use of thrombolysis may have been largely attributable to structural factors; however, with the widespread implementation of 24/7 hyper acute stroke services, continuing variation is likely to reflect differences in clinical decision-making, in particular the influence of ambiguous areas within the guidelines, licensing criteria and research evidence. Clinicians' perceptions about thrombolysis may now exert a greater influence on treatment rates than structural/service factors. This research seeks to elucidate factors influencing thrombolysis decision-making by using patient vignettes to identify (1) patient-related and clinician-related factors that may help to explain variation in treatment and (2) associated trade-offs in decision-making based on the interplay of critical factors. A discrete choice experiment (DCE) will be conducted to better understand how clinicians make decisions about whether or not to offer thrombolysis to patients with acute ischaemic stroke. To inform the design, exploratory work will be undertaken to ensure that (1) all potentially influential factors are considered for inclusion; and (2) to gain insights into the 'grey areas' of patient factors. A fractional factorial design will be used to combine levels of patient factors in vignettes, which will be presented to clinicians to allow estimation of the variable effects on decisions to offer thrombolysis. Ethical approval for this study was obtained from the Newcastle University Research Ethics Committee. The results will be disseminated in peer review publications and at national conferences. Findings will be translated into continuing professional development activities

    To improve the scintigraphic detection of bacterial infections a protein charge-purified fraction of polyclonal human immunoglobulin was applied as a radiopharmaceutical. This purification was achieved by attaching the immunoglobulin to an anion-exchanger column and by obtaining the column-bound fraction with buffer. The binding to bacteria in vitro and the target to non-target ratios of an experimental thigh infection with Staphylococcus aureus or Klebsiella pneumoniae in mice were evaluated to compare the purified and the unpurified immunoglobulin. The percentage of binding to all gram-positive and gram-negative bacteria used in this study was significantly (P 99m Tc-labelled protein charge-purified polyclonal human immunoglobulin was administered intravenously. At all time intervals the target (infected thighs) to non-target (non-infected thighs) ratios for both infections were significantly higher (P 99m Tc-labelled protein charge-purified immunoglobulin localizes both a gram-positive and a gram-negative thigh infection more intensely and faster than 99m Tc-labelled unpurified immunoglobulin.

    We investigated, at diagnosis, the relationship between serum immunoglobulin G4 levels and the main characteristics of Graves' disease: hyperthyroidism severity, goiter size, presence of active Graves' ophthalmopathy, antithyroid antibodies status, and titer. This prospective study included 80 newly diagnosed Graves' disease patients. The main parameters measured at diagnosis: thyroid-stimulating hormone, free thyroxine, free triiodothyronine, total triiodothyronine, thyroglobulin, antithyroid peroxidase antibodies, anti-thyroglobulin antibodies, thyroid-stimulating hormone receptor antibodies, immunoglobulin G4. In Graves' disease patients, serum immunoglobulin G4 levels were higher than in general population (p = 0.028) and higher in men compared to women (p = 0.002). Only one female patient with intense hypoechoic goiter, high anti-thyroglobulin antibody, and antithyroid peroxidase antibody titers had an elevated serum immunoglobulin G4 level at diagnosis. Patients with immunoglobulin G4 levels above the 75th percentile (>237.52 mg/dl, N = 20) were younger at Graves' ophthalmopathy onset (p 286.28 mg/dl, N = 8) had lower total triiodothyronine values (p = 0.001) than patients with IgG below the 90th percentile. No significant correlations were found between smoking status (p = 0.58), goiter size (p = 0.50), the presence of ophthalmopathy (p = 0.42) or thyroid-stimulating hormone receptor antibody titers (p = 0.45) and the mean value of immunoglobulin G4 levels at diagnosis. Our data suggest that Graves' disease patients with elevated immunoglobulin G4 levels at diagnosis have a phenotype characterized by higher anti-thyroglobulin antibody and antithyroid peroxidase antibody titers, less severe T3 hyperthyroidism, younger age at ophthalmopathy onset and require a shorter duration of the first methimazole treatment cycle.

    Open treatment of femoroacetabular impingement (FAI) through a surgical hip dislocation (SHD) approach has been reported to allow for improvement in pain and function. However, the approach require a trochanteric osteotomy and may be associated with high level of pain after surgery. Currently, there is no systematic approach for pain management after SHD for treatment of FAI. A retrospective chart review was used to collect data from 121 subjects (12 to 21 y and below) who received periarticular local infiltration analgesia (LIA, n=20), epidural analgesia (n=72), or intravenous patient-controlled analgesia (PCA, n=29) after SHD from January 2003 to June 2014. Verbal pain scores, opioid consumption, incidence of side effects/complications, and length of hospital stay (LOS) were recorded. All nonopioid medications with analgesic potential were included in the statistical models as potential confounding variables RESULTS:: Twelve hours after surgery, the odds of moderate/severe pain were higher in the PCA group (odds ratio, 20.5; 95% confidence interval (CI), 1.7-243.8; P=0.0166] and epidural group (odds ratio, 5.2; 95% CI, 0.7-92.0; P=0.3218) compared with the LIA group. There was no difference in pain scores across all groups 1 hour (P=0.0675) or 24 hours (P=0.3473) postoperatively. Total opioid consumption in the LIA group was 59.8% (95% CI, 15.0%-81.0%; P=0.0175) lower than the total opioid consumption in the epidural group and 60.7% (95% CI, 17.3-81.3; P=0.0144) lower than the total opioid consumption in the PCA group. LOS was increased in the epidural (mean difference, 22.1; 95% CI, 6.8-37.4 h; P=0.0051) and PCA (mean difference, 16 h; 95% CI, 1-31.5 h; P=0.0367) groups relative to the LIA group. There was 0 (0%) complication in the LIA group compared with 11 (15.3%) in the epidural group. LIA was more effective at controlling pain 12 hours after surgery in comparison with PCA with similar pain control to epidural. LIA was associated with significantly lower

Hoffmann La-Roche Ltd, Basel, Switzerland; 4Clinical Outcomes Solutions, Tucson, AZ, USA Background: A subcutaneous (SC formulation of rituximab (MabThera®/Rituxan® has been developed that could reduce administration time and improve patient satisfaction with treatment. The Rituximab Administration Satisfaction Questionnaire (RASQ was created to assess patients’ perceptions and satisfaction with rituximab SC (RASQ-SC or rituximab intravenous (RASQ-IV. We assessed the content validity and psychometric properties of RASQ in patients with non-Hodgkin lymphoma.Methods: Face and content validity of RASQ-SC and RASQ-IV were qualitatively assessed using 60-minute combined concept elicitation and cognitive debriefing interviews. Psychometric validation of RASQ (item performance and reliability was assessed quantitatively against the established Cancer Therapy Satisfaction Questionnaire (CTSQ, using questionnaire data from the PrefMab (NCT01724021 and MabCute (NCT01461928 clinical studies.Results: RASQ-IV demonstrated excellent coverage of concepts relevant to patients’ (n=10 own treatment experiences and no new concepts were identified. Patients’ expectations of rituximab SC were conceptually consistent with items included in the RASQ-SC, suggesting that the tool is also conceptually adequate. In 1,051 patients from PrefMab and MabCute, correlations with domains such as “RASQ: Physical Impacts” and “CTSQ: Feelings About Side Effects”, “RASQ: Physical Impacts” and “CTSQ: Satisfaction With Therapy”, and “RASQ: Satisfaction” and “CTSQ: Satisfaction With Therapy”, achieved moderate-to-high correlations (>0.4 for convergent domains and <0.3 for divergent domains.Conclusion: This study supports the qualitative face and

    Chemotherapy and targeted drugs are important tools in the treatment of malignant diseases. A number of the planned treatments are cancelled late which is a great challenge for the clinic to minimize in order to prevent the risk for misused resources. The aim of this study was to analyze the frequency and reasons for late (Karolinska University Hospital. The survey comprehends the vast majority of all such treatment for solid tumors in adult patients in the Stockholm region with two million inhabitants. All bookings and late cancellations including their reasons were recorded. Diagnoses, treatment indication, line of treatment and survival, in particular short term survival, were analyzed. Almost 3000 bookings for 1460 patients were included and 13% were cancelled late. Patient detoriation was the dominating cause for late cancellation in patients with palliative treatment (59%), while hematological toxicity was most common in the adjuvant group (42%). The most common treatment indication was palliative (62%). Of the palliative treatments, 95% where given in the first to third treatment line. Breast cancer (31.9%) and colorectal cancer (29.9%) were the two most common diagnoses. Seventy-one patients (4.9%) died within two months after the treatment. A more careful selection and monitoring of the patients might reduce the number of late cancellations due to patient detoriation. To record performance status (PS) as a routine for all patients might be helpful in that process. If the number of late cancellations could be reduced, resources at the clinic could be used more efficiently.

    Post-surgical meningitis and/or ventriculitis caused by Gram-negative bacteria may be difficult to treat due to the emergence of multiresistant strains. Two patients with multiresistant Acinetobacter baumannii central nervous system infection, successfully treated with either intravenous and/or intraventricular colistin are presented. Unresolved issues such as dose and duration of intraventricular colistin are discussed.

    Flat panel detector CT angiography with intravenous contrast agent injection (IV CTA) allows high-resolution imaging of cerebrovascular structures. Artifacts caused by metallic implants like platinum coils or clips lead to degradation of image quality and are a significant problem. To evaluate the influence of a prototype metal artifact reduction (MAR) algorithm on image quality in patients with intracranial metallic implants. Flat panel detector CT after intravenous application of 80 mL contrast agent was performed with an angiography system (Artis zee; Siemens, Forchheim, Germany) using a 20 s rotation protocol (200° rotation angle, 20 s acquisition time, 496 projections). The data before and after MAR of 26 patients with a total of 34 implants (coils, clips, stents) were independently evaluated by two blinded neuroradiologists. MAR improved the assessability of the brain parenchyma and small vessels (diameter metallic implants and at a distance of 6 cm (p<0.001 each, Wilcoxon test). Furthermore, MAR significantly improved the assessability of parent vessel patency and potential aneurysm remnants (p<0.005 each, McNemar test). MAR, however, did not improve assessability of stented vessels. When an intravenous contrast protocol is used, MAR significantly ameliorates the assessability of brain parenchyma, vessels, and treated aneurysms in patients with intracranial coils or clips.

    The purpose of this study was to report the visual and anatomical outcomes of an intravenous microdose of 10 mg of bevacizumab in a patient with a vascularized pigment epithelial detachment (PED) associated with exudative age-related macular degeneration refractory to several intravitreal bevacizumab injections. Interventional case report and literature review. A 62-year-old female patient with a PED secondary to age-related macular degeneration was treated with 9 consecutive intravitreal injections of 2.5 mg of bevacizumab. Despite an initial response where the PED decreased in size, the subretinal fluid reabsorbed and the visual acuity improved; after the seventh injection, the PED started to grow in size again causing a drop in visual acuity. After an intravenous injection of 10 mg of bevacizumab, the patient experienced an improvement in visual acuity and a flattening of her PED. An intravenous injection of a microdose of bevacizumab appears to have resolved the PED with a sustained improvement of visual acuity.

    Heat-treatment of colostrum is a method developed to reduce calf exposure to pathogens. Infrared (IR) spectroscopy and Brix refractometers can be used for measuring colostral IgG concentration and assessing colostrum quality. To determine the impact of heat-treatment on accuracy of IR spectroscopy and Brix refractometers for measuring colostral IgG concentration and assessing colostrum quality before and after heat-treatment. A total of 60 Holstein dairy cows on 8 commercial dairy farms. A cross-sectional study was designed to determine the effect of heat-treatment at 60°C and 63°C each for 30 and 60 minutes duration on colostral IgG concentration measured by the reference radial immunodiffusion (RID) assay, IR spectroscopy, and digital and optical refractometers. Colostrum IgG concentration significantly decreased after heat-treatment at 63°C for 30 or 60 minutes as measured by RID, but the IgG values remained unchanged when measured by IR spectroscopy and refractometers. The lowest correlation coefficient found between IR spectroscopy (r = 0.70) and RID results was in colostrum heat-treated at 63°C for 60 minutes. For digital (r = 0.48) and optical (r = 0.50) refractometers, the lowest correlation coefficient was at 63°C for 30 minutes when compared to RID. The accuracy of the IR spectroscopy, digital and optical Brix refractometers was decreased from 91.7 to 80%, 81.7 to 45%, and 80 to 45%, respectively, when colostrum heat-treated at 63°C for 60 minutes. Radial immunodiffusion, IR spectroscopy, and Brix refractometers exhibit utility for measuring IgG concentration when colostrum heat-treated at 60°C but does not detect decrease IgG concentrations when heat-treated at 63°C.

    Full Text Available Immunoglobulin G4-related disease (IgG4-RD is an increasingly recognized immune-mediated condition comprised of a collection of disorders that share specific pathological, serological, and clinical features. IgG4-RD is a fibroinflammatory condition with a tendency to form tumors with inflammatory infiltrate with IgG4 rich plasma cells and elevation of serum IgG4, which may affect virtually every organ and tissue. IgG4-related ophthalmic disease may present as dacryoadenitis, myositis, or involvement of other orbital tissue. Hypophysitis or pachymeningitis may manifest as cranial neuropathies. The diagnosis of IgG4-RD is based on a typical clinical scenario, supportive laboratory test, expected radiological characteristics, and distinct histopathological and immunohistochemical features. Corticosteroids and immunosuppressives form the mainline treatment.

    The effect of reperfusion with intravenous streptokinase for acute myocardial infarction (AMI) was assessed by myocardial scintigraphy in 6 patients using {sup 99m}Tc-MIBI injected before and 48 hours after the thrombolysis. All patients showed 3 to 4 segmental defects consistent for AMI in the baseline study. The post-thrombolytic study showed an intense reperfusion in 3 patients, a moderate reperfusion in 2 patients and absence of reperfusion in one patient. These findings indicate that the dual imaging strategy with {sup 99m}Tc-MIBI is an effective non-invasive technique to assess the effectiveness of reperfusion in acute myocardial infarcted areas.

    Indications for direct visualization of the bile ducts include bile duct dilatation demonstrated by ultrasound or computed tomography (CT) scanning, where the cause of the bile duct dilatation is uncertain or where the anatomy of bile duct obstruction needs further clarification. Another indication is right upper quadrant pain, particularly in a post-cholecystectomy patient, where choledocholithiasis is suspected. A possible new indication is pre-operative evaluation prior to laparoscopic cholecystectomy. The bile ducts are usually studied by endoscopic retrograde cholangiopancreatography (ERCP), or, less commonly, trans-hepatic cholangiography. The old technique of intravenous cholangiography has fallen into disrepute because of inconsistent bile-duct opacification. The advent of spiral CT scanning has renewed interest in intravenous cholangiography. The CT technique is very sensitive to the contrast agent in the bile ducts, and angiographic and three-dimensional reconstructions of the biliary tree can readily be obtained using the CT intravenous cholangiogram technique (CT IVC). Seven patients have been studied using this CT IVC technique, between February 1995 and June 1996, and are the subject of the present report. Eight further studies have since been performed. The results suggest that CT IVC could replace ERCP as the primary means of direct cholangiography, where pancreatic duct visualization is not required. (authors)

    Full Text Available The experimental model of paracoccidioidomycosis induced in mice by the intravenous injection of yeast-forms of P. brasiliensis (Bt2 strain; 1 x 10(6 viable fungi/animal was used to evaluate sequentially 2, 4, 8, 16 and 20 weeks after inoculation: 1. The presence of immunoglobulins and C3 in the pulmonary granuloma-ta, by direct immunofluorescence; 2. The humoral (immunodiffusion test and the cellular (footpad sweeling test immune response; 3. The histopathology of lesions. The cell-immune response was positive since week 2, showing a transitory depression at week 16. Specific antibodies were first detected at week 4 and peaked at week 16. At histology, epithelioid granulomas with numerous fungi and polymorphonuclear agreggates were seen. The lungs showed progressive involvement up to week 16, with little decrease at week 20. From week 2 on, there were deposits of IgG and C3 around fungal walls within the granulomas and IgG stained cells among the mononuclear cell peripheral halo. Interstitital immunoglobulins and C3 deposits in the granulomas were not letected. IgG and C3 seen to play an early an important role in. the host defenses against P. brasiliensis by possibly cooperating in the killing of parasites and blocking the antigenic diffusion.

  12. Is dosing of therapeutic immunoglobulins optimal? – A review of a 3-decade long debate in Europe.

    Full Text Available The consumption of immunoglobulins (Ig is increasing due to better recognition of antibody deficiencies, an aging population and new indications. This review aims to examine the various dosing regimens and research developments in the established and in some of the relevant off-label indications in Europe. The background to the current regulatory settings in Europe is provided as a backdrop for the latest developments in primary and secondary immunodeficiencies and in immunomodulatory indications. In these heterogeneous areas, clinical trials encompassing different routes of administration, varying intervals and infusion rates are paving the way towards more individualized therapy regimens.In primary antibody deficiencies adjustments in dosing and intervals will depend on the clinical presentation, effective IgG trough levels and IgG metabolism. Ideally, individual pharmacokinetic profiles in conjunction with the clinical phenotype could lead to highly tailored treatment. In practice, incremental dosage increases are necessary to titrate the optimal dose for more severely ill patients. Higher intravenous doses in these patients also have beneficial immunomodulatory effects beyond mere IgG replacement. Better understanding of the pharmacokinetics of Ig therapy is leading to a move away from simplistic ‘per kg’ dosing.Defective antibody production is common in many secondary immunodeficiencies irrespective of whether the causative factor was lymphoid malignancies (established indications, certain autoimmune disorders, immunosuppressive agents or biologics. This antibody failure, as shown by test immunisation, may be amenable to treatment with replacement Ig therapy. In certain immunomodulatory settings (e.g. ITP selection of patients for Ig therapy may be enhanced by relevant biomarkers in order to exclude non-responders and thus obtain higher response rates. In this review the developments in dosing of therapeutic immunoglobulins have been

    Postpartum haemorrhage can lead to iron deficiency with and without anaemia, the clinical consequences of which include physical fatigue. Although oral iron is the standard treatment, it is often associated with gastrointestinal side effects and poor compliance. To date, no published randomised controlled studies have compared the clinical efficacy and safety of standard medical care with intravenous administration of iron supplementation after postpartum haemorrhage.The primary objective of this study is to compare the efficacy of an intravenous high single-dose of iron isomaltoside 1000 with standard medical care on physical fatigue in women with postpartum haemorrhage. In a single centre, open-labelled, randomised trial, women with postpartum haemorrhage exceeding 700 mL will be allocated to either a single dose of 1,200 mg of iron isomaltoside 1000 or standard medical care. Healthy parturients with a singleton pregnancy will be included within 48 hours after delivery.Participants will complete structured questionnaires that focus on several dimensions of fatigue and mental health (Multidimensional Fatigue Inventory, Edinburgh Postnatal Depression Scale and the Postpartum Questionnaire), at inclusion and at follow-up visits after three days, one week, three weeks, eight weeks, and 12 weeks postpartum. The primary endpoint is the aggregated change in physical fatigue score within 12 weeks postpartum, as measured by a subscale of the Multidimensional Fatigue Inventory. The primary objective will be considered to have been met if an intravenous high single dose of iron isomaltoside 1000 is shown to be superior to standard medical care in women after postpartum haemorrhage regarding physical fatigue.For claiming superiority, we set the minimal clinically relevant difference between the mean scores at 1.8, and the assumed standard deviation at 4.2. Hence, 87 participants per treatment group are needed in order to demonstrate superiority; to provide an extra margin

    Previous reports on the use of radiolabelled immunoglobulins led us to undertake a pilot experiment in an animal model to investigate the potentials sodium pertechnate Tc 99m-immunoglobulin scintigraphy in the detection of infectious foci. Mice infected in one leg with staphylococcus infection in were injected with sodium pertechnote Tc 99m-immunoglobulin, albumin aggregated technetium Tc 99m or gallium citrate Ga 67. The results obtained by scintigraphy suggested a specific accumulation of radiolabelled immunoglobulin at the site of infection. Visualization of the infection and the image quality, especially the 6- and 24-h images, were clearly enhanced after the use of immunoglobulin preparations as compared with those labelled with gallium.

    The efficacy and toxicity of sequential intravenous and oral ciprofloxacin therapy was compared with intravenously administered ceftazidime in a prospective, randomized, controlled, non-blinded trial. Thirty-two patients (16 patients receiving ciprofloxacin and 16 patients receiving ceftazidime) with 38 infections caused by susceptible Pseudomonas aeruginosa, enteric gram-negative rods, Salmonella group B, Serratia marcescens, Pseudomonas cepacia, and Xanthomonas maltophilia at various sites were evaluable for determination of efficacy. Length of therapy varied from seven to 25 days. Concomitant antimicrobials included intravenously administered beta-lactams for gram-positive organisms, intravenous/oral metronidazole and clindamycin for anaerobes, and intravenous/local amphotericin B for Candida albicans. Intravenous administration of 200 mg ciprofloxacin every 12 hours to 11 patients produced peak serum levels between 1.15 and 3.12 micrograms/ml; trough levels ranged between 0.08 and 0.86 micrograms/ml. Overall response rates were similar for patients receiving ciprofloxacin and ceftazidime. Emergence of resistance was similar in both groups--one Enterobacter cloacae and two P. aeruginosa became resistant after ciprofloxacin therapy and two P. aeruginosa became resistant after ceftazidime therapy. The frequency of superinfection with a variety of organisms was also similar in both groups. Adverse events related to ciprofloxacin included transient pruritus at the infusion site and generalized rash leading to drug discontinuation (one patient each), and with ceftazidime adverse effects included pain at the site of infusion and the development of allergic interstitial nephritis (one patient each). Overall, intravenous/oral ciprofloxin therapy appears to be as safe and effective as intravenous ceftazidime therapy in the treatment of a variety of infections due to susceptible aerobic gram-negative organisms.

    Full Text Available We present a case of complex regional pain syndrome (CRPS, in which symptoms, including burning pain and severe allodynia, were alleviated by using a regional intravenous nerve blockade (Bier block combined with physiotherapy, but reappeared following an epileptic seizure. Symptoms disappeared again following control of epileptic discharges, as revealed by single-photon emission computed tomography (SPECT and electroencephalography (EEG results. Although systemic toxicity of a local anesthetic applied by Bier block was suspected as a cause of the first seizure, the patient did not present any other toxic symptoms, and seizures repeatedly occurred after Bier block cessation; the patient was then diagnosed as having temporal symptomatic epilepsy. This case suggests that symptoms of CRPS may be sustained by abnormal brain conditions, and our findings contribute to the understanding of how the central nervous system participates in maintaining pain and allodynia associated with CRPS.

    Immunoglobulin (Ig) therapy is the mainstay of treatment for primary antibody deficiency disorders and has proved to be efficacious in specific autoimmune and inflammatory diseases. Additionally, due to the role of Ig in complement activation, it is being used increasingly in solid organ transplantation. Furthermore, Ig is the primary or secondary treatment in some immune-mediated neuropathies such as chronic inflammatory demyelinating polyneuropathy (CIDP) or multifocal motor neuropathy (MMN). This session discusses trends of Ig use in Europe, proposed mechanisms of action, adverse effects and the potential role of Ig therapy in transplantation. Dr Šedivá reported that Ig therapy is available in all European countries, although dosing is not always optimal, due partly to reimbursement plans. Subcutaneous immunoglobulin (SCIg) has become increasingly accessible in recent years; however, the chosen route of administration still varies widely between countries. Dr Berger's presentation on optimization of Ig therapy in neuropathies, and Dr Rojavin's report on a pharmacometric model to determine the serum IgG levels achieved by different dosing regimens in primary antibody deficiency (PAD) patients, led to the challenging concept of using individualized dosing strategies. Dr Klehmet reported on the potential benefit of using antigen-specific T cell responses as a biomarker of IVIg responsiveness in CIDP patients, while Dr von Gunten provided an insight into the mechanisms of action of Ig preparations, suggesting that the immunoregulatory effects of IgG may be mediated by IgG antibodies against glycans. Dr Basta reported on the potential thrombogenic adverse effects associated with Ig therapy. Although these adverse events are rare, further studies are needed to clarify the relationship between Ig replacement and immunomodulatory therapy and these adverse reactions. In transplantation, Dr Carbone described that prophylactic IVIg treatment was found to decrease the

    Hyper-immunoglobulin D syndrome is a rare autosomal-recessive autoinflammatory syndrome in which a mevalonate kinase deficiency results due to mutations of the mevalonate kinase gene. We report a case of an Asian male infant who was found to have hyper-immunoglobulin D syndrome in the absence of fever. His skin manifestations included cephalic pustulosis as well recurrent transient and fixed pink plaques and nodules on the face and extremities. Subsequent examination revealed hyper-immunoglobulin D syndrome with two novel allelic mutations in the mevalonate kinase gene: c.895G > A (p.D299N) and c.1168C > T (p.Q390). It is important for dermatologists to recognize the varied cutaneous presentations of hyper-immunoglobulin D syndrome because rapid diagnosis and treatment can significantly affect outcomes. © 2018 Wiley Periodicals, Inc.

    In an epidemiological study of the somatic late effects risk following incorporation of a short lived α-emitter, 1473 ankylosing spondylitis patients treated with repeated intravenous injections of 224 Ra in the years 1948 - 75, have been observed in the GSF. The usual therapeutic plan consisted of a total of 10 - 12 injections of 1.036 MBq (28 μCi) of 224 Ra each, given at weekly intervals; this would result in an cumulative α-dose of 0.56 - 0.67 Gy to the marrow-free skeleton of a 70-kg-man (standard man). These patients have been followed together with a control group of ankylosing spondylitis patients not treated with radioactive drugs and/or X-rays. Until May 1993 (mean follow-up time 19.9 yr), 595 patients of the exposure group and 722 patients of the control group have died, causes of death have been ascertained for 578, resp. 668 patients. Among others we observed in the exposure group 10 cases of leukaemia (vs. 2.7 - 2.8 cases expected, p 239 Pu, an α-emitter which like 224 Ra deposits preferentially on the bone surface. (orig.) [de

    Full Text Available Canine parvovirus (CPV is a highly infectious virus. The virus causes death in dogs worldwide. The mortality rate due to infection of CPV in dog reaches 91%. Prevention of CPV infection in puppies has been done by vaccination which is effectively proven. Protective mechanisms of maternal antibodies contribute to the failure of vaccination. Highly stable characteristics of parvovirus enable the virus still exist in the environment. Various therapies are performed only to suppress the clinical symptoms but can not reduce puppy mortalities. This review discusses CPV alternative therapy and the advantages using immunoglobulin Y (IgY specific antibodies isolated from chicken egg yolk. Immunoglobulin Y will neutralize the virus, so it can not infect host cells. Intravenous IgY therapy has shown to suppress the spread of CPV infection and prevent death.

    Immunoglobulins form an important component of the immunological activity found in milk and colostrum. They are central to the immunological link that occurs when the mother transfers passive immunity to the offspring. The mechanism of transfer varies among mammalian species. Cattle provide...... a readily available immune rich colostrum and milk in large quantities, making those secretions important potential sources of immune products that may benefit humans. Immune milk is a term used to describe a range of products of the bovine mammary gland that have been tested against several human diseases....... The use of colostrum or milk as a source of immunoglobulins, whether intended for the neonate of the species producing the secretion or for a different species, can be viewed in the context of the types of immunoglobulins in the secretion, the mechanisms by which the immunoglobulins are secreted...

    Full Text Available During recent years, an increasing number of neuromuscular diseases have been recognized either to be caused primarily by autoimmune mechanisms, or to have important autoimmune components. The involved pathophysiological mechanisms and clinical manifestations have been better recognized and many of these disorders are potentially treatable by immunosuppression or by immunomodulation with intravenous immunoglobulin (IVIg. IVIg has been tried in a variety of immune-mediated neurological diseases, being target of widespread use in central and peripheral nervous systems diseases. Objective To give an overview of the main topics regarding the mechanism of action and different therapeutic uses of IVIg in neurological practice, mainly in neuromuscular diseases.

    2010-01-01

    Purpose of review Due to the well-known toxicities of cyclophosphamide, substantial interest exists in finding other therapies to treat primary systemic vasculitis. Biologic agents have been proposed as an alternative to cyclophosphamide for these disorders because of their recent success in treating other rheumatic diseases. This article reviews the current state-of-the-art with regards to the use of biologic agents as a treatment for systemic vasculitis. Recent findings The greatest amount of experience with these agents for the treatment of systemic vasculitis is with anti-tumor necrosis factor agents, pooled intravenous immunoglobulin, and anti-B cell therapies such as rituximab. Intravenous immunoglobulin is already a standard therapy for Kawasaki's disease, but should also be considered for the treatment of ANCA-associated vasculitis when standard therapies are either ineffective or contraindicated. Early experience with tumor necrosis factor inhibitors indicates that they may be effective for the treatment of Takayasu's arteritis, but their role in the treatment of other forms of vasculitis remains controversial. Early experience with rituximab for the treatment of several forms of vasculitis has been quite promising, but must be confirmed by ongoing randomized clinical trials. Summary Biologic agents represent the next evolution in treatment for the primary systemic vasculitides. Greater understanding of these diseases has allowed use to move further away from non-specific, highly toxic therapies towards a more directed approach. As our experience with these agents increases, they will likely form the keystone of treatment in the near future. PMID:19077713

  6. Ultrasonography versus intravenous urography

    1991-01-01

    The present study was performed to compare the clinical value of urography and ultrasonography in a non-selected group of patients referred for urography to a university hospital. The conslusions and clinical implications of the study are as follows: Intravenous urography remains the cornerstone imaging examination in the evaluation of ureteral calculi. Ultrasonography is a valuable adjunct in cases of non- visualization of the kidneys, in distal obstruction and known contrast media allergy. When women with recurrent urinary tract infection are referred for imaging of the urinary tract, ultrasonography should be used. Ultrasonography should replace urography for screening of non-acute hydronephrosis like in female genital cancer and benign prostate hyperplasia. There is good correlation between urography and ultrasonography in assessing the degree of hydronephrosis. However, more researh on the relationship between hydronephrosis and obstruction is necessary. Ultrasonography should be used as the only imaging method of the upper urinary tract in patients with microscopic hematuria. In patients less than 50 years with macroscopic hematuria, ultrasonography should be used as the only imaging of the upper urinary tract, and an examination of the urinary bladder should be included. In patients over 50 years, urography supplied with ultrasonography should be used, but more research is necessary on the subject of imaging method and age. 158 refs

  7. Immunoglobulin E-Mediated Autoimmunity

    Directory of Open Access Journals (Sweden)

    Marcus Maurer

    2018-04-01

    Full Text Available The study of autoimmunity mediated by immunoglobulin E (IgE autoantibodies, which may be termed autoallergy, is in its infancy. It is now recognized that systemic lupus erythematosus, bullous pemphigoid (BP, and chronic urticaria, both spontaneous and inducible, are most likely to be mediated, at least in part, by IgE autoantibodies. The situation in other conditions, such as autoimmune uveitis, rheumatoid arthritis, hyperthyroid Graves’ disease, autoimmune pancreatitis, and even asthma, is far less clear but evidence for autoallergy is accumulating. To be certain of an autoallergic mechanism, it is necessary to identify both IgE autoantibodies and their targets as has been done with the transmembrane protein BP180 and the intracellular protein BP230 in BP and IL-24 in chronic spontaneous urticaria. Also, IgE-targeted therapies, such as anti-IgE, must have been shown to be of benefit to patients as has been done with both of these conditions. This comprehensive review of the literature on IgE-mediated autoallergy focuses on three related questions. What do we know about the prevalence of IgE autoantibodies and their targets in different diseases? What do we know about the relevance of IgE autoantibodies in different diseases? What do we know about the cellular and molecular effects of IgE autoantibodies? In addition to providing answers to these questions, based on a broad review of the literature, we outline the current gaps of knowledge in our understanding of IgE autoantibodies and describe approaches to address them.

    1991-01-01

    The purpose of this study was to investigate both the ability of 99mTc-labeled polyclonal human immunoglobulin (HIG) to localize an infection and the modes of action involved in this process. Mice, infected with Staphylococcus aureus ATCC 25923 in a thigh muscle, received HIG intravenously. Scintigrams were made 1, 4, and 24 hr later; subsequently the mice were killed and the activity in several organs and thighs was determined. The radiopharmaceutical demonstrated a time-dependent accumulation at the site of infection. It was found that vascular permeability or Fc binding alone could not account for the mode of action of HIG. Neither the origin of Ig (human versus murine) nor the total amount of protein (0.01-1.0 mg Ig per mouse) affected the target-to-background (T/B) ratios. Ratios were not different for leukocytopenic animals. A correlation (p less than 0.001) was demonstrated between the number of bacteria at the site of infection and the T/B ratio. This was also found after antibiotic treatment (p less than 0.02)

    Gasoline, ingested intentionally or accidentally, is toxic. The majority of reported cases of gasoline intoxication involve oral ingestion or inhalation. Data are scarce on complications and outcomes following hydrocarbon poisoning by intravenous injection. Following a suicide attempt by intravenous self-injection of 10 ml of gasoline, a 26-year-old medical student was admitted to the intensive care unit (ICU) with hemoptysis, symptoms of acute respiratory failure, chest pain, and severe abdominal cramps. Gas exchange was severely impaired and a chest x-ray indicated chemical pneumonitis. Initial treatment consisted of mechanical ventilation, supportive hyperventilation, administration of nitrogen oxide (NO), and prednisone. Unfortunately, the patient developed multi-organ dysfunction syndrome (MODS) complicated by life-threatening severe vasoplegia within 24 hours after gasoline injection. High doses of vasopressors along with massive amounts of parenteral fluids were necessary. Despite fluid replacement, renal function worsened and required hemofiltration on 5 sequential days. After 12 days of intensive care management, the patient recovered completely and was discharged to a psychiatric care facility. Intravenous gasoline injection causes major injury to the lungs, the organ bearing the first capillary bed encountered. Treatment of gasoline poisoning is symptomatic because no specific antidote is available. Early and aggressive supportive care may be conducive to a favorable outcome with minimal residual pulmonary sequelae.

Although it has been approved for selected indications, the list of its clinical indications, particularly off-labels, has grown considerably. Unfortunately, many of these conditions, lack sufficient clinical data of efficacy and might not always be appropriate.Method: It was a cross sectional study performed in Amir-al-momenin teaching hospital affiliated to Zabol University of medical sciences. All hospitalized patients who received IVIG during a 6 month period (autumn and winter 2015 were included in this study. We used predesigned data collection forms for data gathering as patient’s demographics, diagnoses, as well as drug related data, such as dose regimen, duration, rate of infusion, any related lab test.Results: In this study total of 49 patients received IVIG. Only in 25 cases, the mentioned indications were FDA approved (51%.Total of 189 IVIG vials (945 grams that cost 146,475,000 Tomans (39481 USD was administered during this study period, of which 560 grams (112vials (59.2% were used for FDA approved indications. From 19 ITP patients only 6 (12.2% fulfilled the criteria for IVIG therapy. Considering cases of wrong doses and whom were not indicated to receive IVIG therapy, total of (93 vials 465 grams, that cost 72,075,000 Tomans (19427 USD were spent irrationally.Conclusion: We concluded that IVIG was widely used irrationally in our institution and cost of this irrational administration is huge. This fact justifies the need for establishing multidisciplinary supervisory procedure in our hospital.

    Treatment-resistant depression patients are more likely to suffer from comorbid physical and mental disorders, experience marked and protracted functional impairment, and incur higher health-care costs than non-affected individuals. Magnesium sulfate is a treatment option that may offer great potential for patients with treatment-resistant depression based on prior work in animals and humans. Twelve subjects with mild or moderate treatment-resistant depression were randomized into a double-blind crossover trial to receive an infusion of 4 g of magnesium sulfate in 5% dextrose or placebo infusion of 5% dextrose with a 5-day washout in between the 8-day intervention period. Subjects were assessed before and after the intervention for serum and urine magnesium, lipid panel, the Hamilton Rating Scale for Depression, and the Patient Health Questionnaire-9. We found a difference in serum magnesium from day 2 to 8 (pre-infusion) (P < 0.002) and from baseline to day 8 (P < 0.02). No changes were noted on the Hamilton Rating Scale for Depression or the Patient Health Questionnaire-9 24 h post-treatment, but as serum magnesium increased from baseline to day 7, the Patient Health Questionnaire-9 decreased from baseline to day 7 (P = 0.02). Magnesium sulfate did not significantly affect depression 24 h post-infusion, but other results were consistent with the literature. The association between changes in serum magnesium and the Patient Health Questionnaire-9 supports the idea that magnesium sulfate may be used to address treatment-resistant depression, an ongoing medical challenge. © 2016 The Authors Psychiatry and Clinical Neurosciences © 2016 Japanese Society of Psychiatry and Neurology.

    To determine the pharmacokinetics of detomidine hydrochloride administered IV (as an injectable formulation) or by the oral-transmucosal (OTM) route (as a gel) and assess sedative effects of the OTM treatment in healthy dogs. 12 healthy adult dogs. In phase 1, detomidine was administered by IV (0.5 mg/m(2)) or OTM (1 mg/m(2)) routes to 6 dogs. After a 24-hour washout period, each dog received the alternate treatment. Blood samples were collected for quantification via liquid chromatography with mass spectrometry and pharmacokinetic analysis. In phase 2, 6 dogs received dexmedetomidine IV (0.125 mg/m(2)) or detomidine gel by OTM administration (0.5 mg/m(2)), and sedation was measured by a blinded observer using 2 standardized sedation scales while dogs underwent jugular catheter placement. After a l-week washout period, each dog received the alternate treatment. Median maximum concentration, time to maximum concentration, and bioavailability for detomidine gel following OTM administration were 7.03 ng/mL, 1.00 hour, and 34.52%, respectively; harmonic mean elimination half-life was 0.63 hours. All dogs were sedated and became laterally recumbent with phase 1 treatments. In phase 2, median global sedation score following OTM administration of detomidine gel was significantly lower (indicating a lesser degree of sedation) than that following IV dexmedetomidine treatment; however, total sedation score during jugular vein catheterization did not differ between treatments. The gel was subjectively easy to administer, and systemic absorption was sufficient for sedation. Detomidine gel administered by the OTM route provided sedation suitable for a short, minimally invasive procedure in healthy dogs.

    A 28-year old female was admitted with recurrent seizures following 2 days of febrile illness, after which she developed status epilepticus. Midazolam and later thiopentone infusions were started after failure of regular intravenous antiepileptics. Burst suppression was achieved at doses of 3 mg/kg/hr for midazolam and 6 mg/kg/hr of thiopentone. Adjunctive medications included methylprednisolone, intravenous immunoglobulin and acyclovir. Imaging and biochemical parameters were normal. She required 3 cycles of midazolam and 2 cycles of thiopentone for complete cessation of seizures. She recovered with mild attentional and recent memory deficits on follow up. Treatment of super-refractory status epilepticus requires individualized regimens and may need doses beyond conventional limits. To the best of our knowledge, there is no such reported case from India.

    Background and purpose: in German-speaking countries, the intravenous treatment of ankylosing spondylitis (AS) with radium-224 ({sup 224}Ra) was common between the late 1940s and 2005. In this long-term investigation, the risk of malignant diseases following intravenous {sup 224}Ra treatment for AS was assessed. Patients and methods: in a prospective long-term study, 1,471 patients with AS who were treated with {sup 224}Ra between 1948 and 1975 have been followed together with a control group of 1,324 AS patients treated neither with radioactive drugs nor with X-rays. Standardized questionnaires to evaluate the patients' health status were used. Observed numbers of malignant diseases were compared with those of the control group as well as with expected numbers for a normal population. Results: After 26 years of follow-up, causes of death have been certified for 1,006 patients of the exposure group (control group: 1,072 patients). Significantly increased rates of myeloid leukemia (12 cases observed vs. 2.9 expected; p < 0.001), kidney cancer (18 vs. 9.1; p < 0.01), thyroid cancer (4 vs. 1.2; p = 0.03) and borderline significantly increased rates of cancer of female genital organs (10 vs. 5.6; p = 0.06) were found in the exposure group in contrast to no significant increases of these diseases in the control group. Rates of pulmonary and gastrointestinal malignancies were not increased. Lymphatic leukemia (exposure group: 8 vs. 2.7; p < 0.01; control group: 7 vs. 3; p = 0.03) was significantly elevated due to a high rate of chronic lymphatic leukemia in both, the exposure as well as the control group. Conclusion: treatment of AS with {sup 224}Ra led to increased incidences of myeloid leukemia and malignancies of kidneys, thyroid and female genital organs. Although this kind of therapy is now abandoned, there is a need for close follow-up of patients who received it. (orig.)

    Patients with stroke symptoms but negative diffusion-weighted imaging (DWI) might have transient ischemic attacks (TIA) or stroke mimics. Brain DWI is important for the diagnosis of cerebral infarction but it is not available before thrombolysis for most patients to avoid treatment delay. This study aimed to evaluate the safety of IV thrombolysis in patients with a negative post-treatment DWI for cerebral infarction. We conducted a retrospective study of 89 patients treated with IV recombinant tissue plasminogen activator (rt-PA) within 4.5 h after stroke symptom onset. The patients were identified in our acute stroke registry from January 2009 to September 2010. Information on patients' demographics, clinical characteristics, neuroimaging, treatment complications, and outcomes was obtained and analyzed. Out of 89 patients, 23 patients (26%) had a negative DWI on follow-up stroke imaging. Fourteen patients had a TIA and nine patients had a stroke mimic, including Todd's paralysis, complicated migraine, and somatoform disorder. We found significant differences between patients with a positive and a negative DWI in mean age (62 years vs. 52 years; P scale score (11 points versus 6 points; P negative DWI had symptomatic or asymptomatic ICH. Our results suggest that the administration of IV rt-PA within the first 4.5 h of symptom onset in patients with suspected ischemic stroke is safe even when post-treatment DWI does not demonstrate cerebral infarction.

    Seventeen consecutive patients with posttraumatic reflex sympathetic dystrophy syndrome (RSDS) were treated with one or more regional i.v. blocks of methylprednisolone sodium succinate and lidocaine HCL after physical therapy and oral medications had failed to produce satisfactory relief of their symptoms. In 12 of these patients the upper extremity was affected, and in five, it was the lower extremity. A fracture of the distal radius was the most frequent predisposing event. The average delay between injury and the manifestation of RSDS was 2.5 months (range 2 days to almost 6 months). The index treatment in all cases started within 3 months of the onset of symptoms. The number of i.v. blocks given ranged from one to four (average 2.4). The side effects and complications were negligible. The treatment, which in most cases was given exclusively on an outpatient basis, was well tolerated by all patients except one. Assessment of 16 of them at 6 months showed that 11 had total or almost total relief of their symptoms. When 15 of the patients were reassessed at an average follow-up of 28 months (range 12-48 months), it was noted that none of the patients with an early satisfactory response experienced recurrence of their symptoms. The condition of the symptomatic patients in the interim had improved overall. Analysis of the cases with an unsatisfactory outcome suggested that the primary reason for failure was inadequate treatment rather than ineffectiveness of the treatment used. It was concluded that this method is simple, safe, and well tolerated and should be regarded as a first choice for posttraumatic RSDS.

    Full Text Available Objective To formulate the best treatment plan for multiple sclerosis (MS patients by evaluating the therapeutic efficacy and side effect of various evidence-based programs. Methods Key words were defined as multiple sclerosis, immunomodulatory therapy and therapy, etc. We searched MEDLINE, Cochrane Library, Wanfang data bases for Scientific Journals in China and National Knowledge Infrastructure for Chinese Scientific Journals Database. Additionally, we applied manual searching and screened out conference paper and academic dissertation, etc, from various references. After that we obtained and evaluated by Jadad scales on systematic reviews, randomized controlled trials, controlled clinical trials and observational study cases about glucocorticoids, plasmapheresis, intravenous immunoglobulin, IFN-β, glatiramer acetate, mitoxantrone, natalizumab, fingolimod. Results After screening, all seventeen selected resources included systematic reviews 6 articles, randomized controlled trials 7 articles, controlled clinical trials 2 articles, observational study cases 2 articles, among which fifteen articles were proved to be high quality (according to Jadad scoring system, five score 4, six score 5, four score 7, two chapters were judged to be low quality scoring 3. Finally, we summerize that: 1 The first choice of treatment for acute relapses is glucocorticoids and we suggest that plasmapheresis or intravenous immunoglobulin may be tried as an alternative therapy in acute MS relapse, especially in case of contraindications to intravenous methylprednisolone. 2 Immunomodulatory or immunosuppressive treatment (IFN-β, glatiramer acetate, mitoxantrone, natalizumab can be an option to prevent new relapses and progression of disability. 3 Fingolimod is an oral treatment for multiple sclerosis to improve treatment adherence. Conclusion Using evidence-based medicine methods can provide us best clinical evidence on MS treatment.

    To evaluate the effects of intravenous immunoglobulin therapy on progression of severe sepsis in patients of poly trauma. Design: Quasi-experimental study. Place and Duration of Study: Combined Military Hospital Peshawar from June 2008 to Dec 2009. Patients and Methods: Forty six patients of poly trauma with severe sepsis were included. Along with the standard management i.e., surgical management, fluid resuscitation, antibiotics, analgesics, ionotropic, ventilatory and nutritional support, IVIG 5% (intravenous immunoglobulin) was infused over a period of 6 hours and repeated for three consecutive days. Sequential Organ Failure Assessment (SOFA) score was used to assess the progress in all the patients. Results: At the time of enrolment mean SOFA score was 5.41+- 1.127 and on the 15 day it was 1.62 +- 2.24, mean age was 39.21+10.26 years. Thirty four patients (73.91%) developed gram negative sepsis and eighteen patients (39.13%) developed septic shock. Mean duration of stay in ICU and on ventilatory support was 20.80+9.61 and 10.52 + 5.52 days respectively. Thirty five days mortality rate of these patients was 30.43%. Conclusion: The IVIG administration, when used along with the standard management appears to improve significantly the prognosis in patients of poly trauma with severe sepsis. (author)

TERalb equals the lymphatic return rate of albumin provided the transport mechanisms are filtrative-convective (i.e. no local back transport). Additional measurements in five pigs...... with proteins of different molecular size confirmed a dominating filtrative-convective transport. The increased TERalb during diuretic medication is best explained by an increased lymph drainage, which may decrease interstitial fluid pressure and thereby increase the transmural capillary pressure difference...... being essential for a filtrative-convective transvascular albumin transport. Increased lymph drainage may contribute to the therapeutic effect of diuretic treatment in oedema and ascites....

    A phase II trial was carried out by the Grupo Oncologico Cooperativo del Sur (G.O.C.S.) to assess the efficacy and toxicity of a biochemical modulation of 5-fluorouracil (5-FU) by i.v. pretreatment with interferon (IFN)-alpha2b in patients with advanced colorectal carcinoma refractory to previous therapy with 5-FU modulated by methotrexate (MTX) or leucovorin (LV) or both. Between January 1993 and October 1995, 34 patients were entered on the study. The treatment was IFN-alpha2b 5 x 10(6)/m2 IU in a 1-h i.v. infusion, followed immediately by 5-FU 600 mg/m2 i.v. bolus injection. Courses were repeated weekly until observation of progressive disease or severe toxicity. One patient could not be assessed for response. Objective regression was observed in 2 of 33 patients (6%, 95% confidence interval, 0%-14%). No patient achieved a complete response. Two patients had partial responses (6%). No change was recorded in 14 patients (41%), and progressive disease occurred in 17 (52%). The median time to treatment failure was 3 months, and the median survival was 5 months. Toxicity was within acceptable limits. The main side effects were mucositis and diarrhea. Four episodes of grade 2 stomatitis were observed, causing dosage modifications. The most frequent toxic effects attributable to IFN-alpha2b were mild fatigue and fever. In conclusion, second-line therapy with i.v. IFN-alpha2b preceding 5-FU has shown an interesting profile of activity in a patient population with clearly unfavorable characteristics. From this perspective, further appropriately designed studies are needed to identify the greatest potential of IFN-alpha2b as a modulator of 5-FU.

    Hospitalized patients are at increased risk for candidemia and invasive candidiasis (C/IC). Improved therapeutic regimens with enhanced clinical and pharmacoeconomic outcomes utilizing existing antifungal agents are still needed. An open-label, non-comparative study evaluated an intravenous (i.v.) to oral step-down strategy. Patients with C/IC were treated with i.v. anidulafungin and after 5 days of i.v. therapy had the option to step-down to oral azole therapy (fluconazole or voriconazole) if they met prespecified criteria. The primary endpoint was the global response rate (clinical + microbiological) at end of treatment (EOT) in the modified intent-to-treat (MITT) population (at least one dose of anidulafungin plus positive Candida within 96 hours of study entry). Secondary endpoints included efficacy at other time points and in predefined patient subpopulations. Patients who stepped down early (≤ 7 days' anidulafungin) were identified as the "early switch" subpopulation. In total, 282 patients were enrolled, of whom 250 were included in the MITT population. The MITT global response rate at EOT was 83.7% (95% confidence interval, 78.7-88.8). Global response rates at all time points were generally similar in the early switch subpopulation compared with the MITT population. Global response rates were also similar across multiple Candida species, including C. albicans, C. glabrata, and C. parapsilosis. The most common treatment-related adverse events were nausea and vomiting (four patients each). A short course of i.v. anidulafungin, followed by early step-down to oral azole therapy, is an effective and well-tolerated approach for the treatment of C/IC. ClinicalTrials.gov: NCT00496197.

    Immunoglobulin is a key factor of the immune response resulting from B-cell activation and associated with T-cell stimulation. Because of its structure, this antibody has a dual function: it specifically recognizes the inducer antigen in the variable region and eliminates it by a constant portion which is responsible for effector properties. Surface immunoglobulin, therefore, is the B-cell antigen receptor; it differs from the T-cell receptor in that it recognizes the antigen unbound to the major istocompatibility complex; binding the antigen results in direct signal transduction first in the cytoplasm, then in the nucleus. This receptor can be secreted in the body: it is made up of circulating immunoglobulins. Human immunoglobulins are divided into 5 classes, each of them with its own response kinetics, distribution and functions. The variability of the antibody response accounts for a genetic organization involving numerous genes which may be associated with each other, or mutate, or recombine during maturation of the lymphocytes. Altogether, this system has a theoretical capacity of response to three hundred million different antigens.

    Hemolytic disease of the fetus and newborn (HDFN) remains a serious pregnancy complication which can lead to severe fetal anemia, hydrops and perinatal death. Areas covered: This review focusses on the current prenatal management, treatment with intrauterine transfusion (IUT) and promising non-invasive treatment options for HDFN. Expert commentary: IUTs are the cornerstone in prenatal management of HDFN and have significantly improved perinatal outcome in the past decades. IUT is now a relatively safe procedure, however the risk of complications is still high when performed early in the second trimester. Non-invasive management using intravenous immunoglobulin may be a safe alternative and requires further investigation.

    Iron deficiency is a common nutritional deficiency amongst women of childbearing age. Peri-partum iron deficiency anaemia (IDA) is associated with significant maternal, fetal and infant morbidity. Current options for treatment are limited: these include oral iron supplementation, which can be ineffective and poorly tolerated, and red blood cell transfusions, which carry an inherent risk and should be avoided. Ferric carboxymaltose is a new treatment option that may be better tolerated.The study was designed to assess the safety and efficacy of iron deficiency anaemia (IDA) correction with intravenous ferric carboxymaltose in pregnant women with mild, moderate and severe anaemia in the second and third trimester. Prospective observational study; 65 anaemic pregnant women received ferric carboxymaltose up to 15 mg/kg between 24 and 40 weeks of pregnancy (median 35 weeks gestational age, SD 3.6). Treatment effectiveness was assessed by repeat haemoglobin (Hb) measurements and patient report of well-being in the postpartum period. Safety was assessed by analysis of adverse drug reactions and fetal heart rate monitoring during the infusion.

    To establish the effects of plasma volume expansion (PVE) followed by intravenous dihydralazine (DH) administration on maternal whole blood viscosity (WBV) and hematocrit, uteroplacental and fetoplacental downstream impedance and umbilical venous (UV) volume flow in pre-eclampsia. In 13 pre-eclamptic women maternal and fetal hemodynamics were established by means of combined measurement of maternal arterial blood pressure (BP), WBV, hematocrit and uterine artery (UtA) resistance index (RI) in addition to umbilical artery (UA) pulsatility index (PI) and UV volume flow obtained from UV vessel area and UV time-averaged flow velocity. In each woman all parameters were measured four times at baseline, after PVE, after DH and 24 h after the start of treatment. Maternal diastolic BP, hematocrit and WBV display a significant reduction after PVE. In the fetus UA PI decreases significantly whereas a significant increase in UV cross-sectional area was detected. After maternal DH administration, arterial systolic and diastolic BP and UA PI show a significant decrease compared with the measurements following PVE. At 24 h, only maternal systolic and diastolic BP display a significant further decrease. No significant changes were established for the UtA RI, UV time-averaged velocity and UV volume flow during the entire study period. During pre-eclampsia, maternal PVE followed by DH administration results in a significant reduction in maternal diastolic BP, maternal hematocrit and WBV. Maternal PVE is associated with a significant increase in UV cross-sectional area and a non-significant rise of 11% in UV volume flow. Maternal DH administration does not result in any change in UV cross-sectional area. However, UA PI decreases significantly after both PVE and DH treatment. Copyright 2004 ISUOG.

    The technology of antivenom production has gradually changed since the earliest production of antisera around the turn of the 20th century. Use of early antisera was associated with frequent acute adverse reactions and serum sickness. New F(ab')2 products, manufactured using pepsin degradation of immunoglobulin together with precipitation of unwanted protein and albumin serum fractions, should in concept cause fewer immune reactions in clinical use. A linked set of five prospective clinical trials of an equine F(ab')2 antivenom, together with one historical control study, were completed during development of the product for a Biological License Application through the US FDA. Adverse events were recorded and categorized, with particular attention to the frequency of immune reactions. A total of 1534 patients ages 0.1-90.5 years received antivenom, in Arizona and in Mexico, for treatment of scorpion envenomation. Total dosing ranged from 1 to 5 vials except for one outlier who received 10 vials. Estimated protein exposure was 12-275 mg per patient (outlier, up to 550 mg). Three patients (0.2%) had acute reactions to antivenom infusion (one urticaria, one urticaria and dyspnea, and one panic attack). Eight (0.5%) had rashes suggestive of Type 3 immune reactions, although none had the full syndrome of serum sickness. Two women were treated for envenomation during the first trimester of pregnancy, one of whom subsequently experienced a spontaneous abortion. Rates of immune reaction to this product were two orders of magnitude lower than the range (up to 75% for early and 81% for late reactions) historically reported with use of minimally refined whole immunoglobulin products against a variety of infections and envenomations. Lower protein dose, greater purity of the active component, lack of the immunogenic Fc portion of the immunoglobulin molecule, and slow intravenous infusion are likely to be the reason for this. Clinical implications of a safer product include that

    Patients with immunoglobulin light chain amyloidosis are at risk for both thrombotic and bleeding complications. While the hemostatic defects have been extensively studied, less is known about thrombotic complications in this disease. This retrospective study examined the frequency of venous thromboembolism in 929 patients with immunoglobulin light chain amyloidosis presenting to a single referral center, correlated risk of venous thromboembolism with clinical and laboratory factors, and examined complications of anticoagulation in this population. Sixty-five patients (7%) were documented as having at least one venous thromboembolic event. Eighty percent of these patients had events within one year prior to or following diagnosis. Lower serum albumin was associated with increased risk of VTE, with a hazard ratio of 4.30 (CI 1.60-11.55; P=0.0038) for serum albumin less than 3 g/dL compared to serum albumin greater than 4 g/dL. Severe bleeding complications were observed in 5 out of 57 patients with venous thromboembolism undergoing treatment with anticoagulation. Prospective investigation should be undertaken to better risk stratify these patients and to determine the optimal strategies for prophylaxis against and management of venous thromboembolism.

    To review the pharmacology, pharmacokinetics, efficacy, safety, dosage and administration, potential drug-drug interactions, and place in therapy of the intravenous (IV) formulation of carbamazepine (Carnexiv) for the treatment of seizures in adult patients. A comprehensive PubMed and EBSCOhost search (1945 to August 2017) was performed utilizing the keywords carbamazepine, Carnexiv, carbamazepine intravenous, IV carbamazepine, seizures, epilepsy, and seizure disorder. Additional data were obtained from literature review citations, manufacturer's product labeling, and Lundbeck website as well as Clinicaltrials.gov and governmental sources. All English-language trials evaluating IV carbamazepine were analyzed for this review. IV carbamazepine is FDA approved as temporary replacement therapy for treatment of adult seizures. Based on a phase I trial and pooled data from 2 open-label bioavailability studies comparing oral with IV dosing, there was no noted indication of loss of seizure control in patients switched to short-term replacement antiepileptic drug therapy with IV carbamazepine. The recommended dose of IV carbamazepine is 70% of the patient's oral dose, given every 6 hours via 30-minute infusions. The adverse effect profile of IV carbamazepine is similar to that of the oral formulation, with the exception of added infusion-site reactions. IV carbamazepine is a reasonable option for adults with generalized tonic-clonic or focal seizures, previously stabilized on oral carbamazepine, who are unable to tolerate oral medications for up to 7 days. Unknown acquisition cost and lack of availability in the United States limit its use currently.

    The National Service Framework advocates correction of anaemia in patients with chronic kidney disease (CKD). Oral iron is insufficient, while intravenous (IV) supplementation replenishes and maintains iron stores. In Yorkshire numerous peripheral clinics exist to reduce travel for patients, but patients must travel to the main unit for IV iron therapy. Therefore an outpatient service in tandem with a routine clinic for administration of IV CosmoFer was created. To evaluate the feasibility and benefits of IV iron therapy in the outpatient clinic during active patient review for CKD patients. A cross-sectional study of patients attending for total dose IV iron (n = 57) at a peripheral clinic. Iron was administered and monitored according to protocol by one of the clinic nurses with medical staff available in the adjoining room. Haemoglobin, ferritin and renal function were recorded pre-infusion and after 4-6 months. Results are given as medians/means +/- standard error. A total of 76 IV infusions were carried out with no reported side effects or haemodynamic instability. Haemoglobin (median 10.9 vs. 11.3 g dL(-1), P = NS), creatinine and estimated glomerular filtration rate (eGFR) over the 6-month period remained stable. Serum ferritin rose significantly [80.9 +/- 6.2 vs. 186.4 +/- 18.2 g L(-1) (P Hospital time saved 380 day case bed hours, doctor hours saved 76 hours, and patient hours saved 3 hours/patient. Cost savings for TDI CosmoFer in peripheral clinic versus in centre therapy and versus sucrose, respectively, for 76 treatments was pound 5749.40 and pound 46,320.80 respectively. We have demonstrated, in a resource-limited service, the feasibility and cost-effectiveness of a management care pathway for patients with CKD, in a peripheral clinic, to receive total dose IV CosmoFer without disruption of a functioning renal clinic.

Comparative studies of SC versus IV, IM versus IV, or IM versus SC have been sporadically conducted, and some new findings are completely different from the dosage recommendation as described in prescribing information. However, clinicians may still be ignorant of such new evidence-based findings when choosing treatment methods.Methods: A literature search was performed using PubMed, MEDLINE, and Web of Sciences™ Core Collection to analyze the advantages and disadvantages of SC, IV, and IM administration in head-to-head comparative studies.Results: “SC better than IV” involves trastuzumab, rituximab, antitumor necrosis factor medications, bortezomib, amifostine, recombinant human granulocyte-macrophage colony-stimulating factor, granulocyte colony-stimulating factor, recombinant interleukin-2, immunoglobulin, epoetin alfa, heparin, and opioids. “IV better than SC” involves ketamine, vitamin K1, and abatacept. With respect to insulin and ketamine, whether IV has advantages over SC is determined by specific clinical circumstances. “IM better than IV” involves epinephrine, hepatitis B immunoglobulin, pegaspargase, and some antibiotics. “IV better than IM” involves ketamine, morphine, and antivenom. “IM better than SC” involves epinephrine. “SC better than IM” involves interferon-beta-1a, methotrexate, human chorionic gonadotropin, hepatitis B immunoglobulin, hydrocortisone, and morphine.

    Full Text Available Immunoglobulin G4-related disease(IgG4-related diseasehas received lots of attention in medical community as a recently recognized fibro-inflammatory condition. It is characterized by infiltration of IgG4-immunopositive plasmacytes and concentration of elevated serum IgG4. IgG4-related disease shows organ enlargement or nodular/hyperplastic lesions in various organs including the pancreas, hepatobiliary tract and orbit, which is called IgG4-related orbital disease. The diagnostic criteria for IgG4-related disease and IgG4-related orbital disease has recently been established, which is based on clinical, imaging and histopathologic features of the orbital lesions. Besides, attention should be drawn to the differentiation from other diseases. The treatment is empirical including corticosteroids, immunosuppressive drugs, radiotherapy, and rituximab.

    A practical field method for measuring immunoglobulin concentration in bovine colostrum has been developed from the linear relationship between colostral specific gravity and immunoglobulin concentration. Fourteen colostrums were collected within 24 h postpartum from nursed and unnursed cows and were assayed for specific gravity and major colostral constituents. Additionally, 15 colostrums were collected immediately postpartum prior to suckling and assayed for specific gravity and immunoglobulin concentration. Regression analysis provided an equation to estimate colostral immunoglobulin concentration from the specific gravity of fresh whole colostrum. From this, a colostrometer was developed for practical field use.

    Oritavancin is a lipoglycopeptide with bactericidal activity against Gram-positive organisms. Its rapid concentration-dependent bactericidal activity and long elimination half-life allow single-dose treatment of acute bacterial skin and skin structure infections (ABSSSI). SOLO I and SOLO II were randomized, double-blind studies evaluating the efficacy and safety of a single 1,200-mg intravenous (i.v.) dose of oritavancin versus twice-daily i.v. vancomycin for 7 to 10 days in ABSSSI patients. Safety data from both studies were pooled for safety analysis. The database comprised pooled safety data for 976 oritavancin-treated patients and 983 vancomycin-treated patients. The incidences of adverse events, serious adverse events, and discontinuations due to adverse events were similar for oritavancin (55.3, 5.8, and 3.7%, respectively) and vancomycin (56.9, 5.9, and 4.2%, respectively). The median time to onset (3.8 days versus 3.1 days, respectively) and the duration (3.0 days for both groups) of adverse events were also similar between the two groups. The most frequently reported events were nausea, headache, and vomiting. Greater than 90% of all events were mild or moderate in severity. There were slightly more infections and infestations, abscesses or cellulitis, and hepatic and cardiac adverse events in the oritavancin group; however, more than 80% of these events were mild or moderate. Subgroup analyses did not identify clinically meaningful differences in the incidence of adverse events attributed to oritavancin. A single 1,200-mg dose of oritavancin was well tolerated and had a safety profile similar to that of twice-daily vancomycin. The long elimination half-life of oritavancin compared to that of vancomycin did not result in a clinically meaningful delay to the onset or prolongation of adverse events.

    One hundred and twenty cases of clinically diagnosed rheumatoid arthritis, 80 non-rheumatoid cases suffering from various other diseases and 40 healthy individuals were investigated for the presence of rheumatoid factor, quantitation of serum immunoglobulin, demonstration of ANA and LE cell phenomenon. Microlatex agglutination test of serum for rheumatoid factor showed 56.6% positivity in rheumatoid group and 3.7% positivity in non-rheumatoid group. All three serum immunoglobulins (IgG, IgM, IgA) were raised in serum in significant titre in cases of rheumatoid arthritis, whereas only IgA lever was elevated in the group of non-rheumatoid diseases. ANA and LE cell phenomenon were observed in 11.7% and 4.4% cases of rheumatoid arthritis who had severe underlying disease. In non-rheumatoid group, only one of 6 cases of systemic lupus erythematosus showed rheumatoid factor and that too in an insignificant titre (less than 1:20). Synovium and synovial fluid contained plenty of plasma cells and lymphocytes. It has been observed that RF appears first in synovial fluid and it may take several months to a year to attain detectable level in serum.

    The ability to diagnose and localize vascular graft infections has been a major challenge. Recent studies in animal models and humans with focal bacterial infection have shown that radiolabeled, polyclonal, human immunoglobulin G accumulates at the site of inflammation and can serve as the basis for an imaging technique. This study investigated this new technique for the diagnosis and localization of vascular graft infections. Twenty-five patients with suspected vascular infections involving grafts (22), atherosclerotic aneurysms (2), and subclavian vein thrombophlebitis (1) were studied. Gamma camera images of the suspected area were obtained between 5 and 48 hours after intravenous administration of 1.5 to 2.0 mCi (56 to 74 mBq) of indium 111-labeled, human, polyclonal immunoglobulin G. Scan results were interpreted without clinical information about the patient and were subsequently correlated with surgical findings, other imaging modalities, and/or clinical follow-up. In 10 of 10 patients found to have positive scan results, localized infections were confirmed at the involved sites. In 14 of 15 patients whose scan results were interpreted as negative, no vascular infections were identified at follow-up. The patient with false-negative results and recurrent bacteremia from an aortoduodenal fistula was found to have a negative scan outcome at a time when his disease was quiescent. These data suggest that nonspecific, human, indium 111-labeled immunoglobulin G scanning can be a useful noninvasive means of localizing vascular infections

    Conclusion: The relation of immunoglobulin concentration with increasing duration of wear and material of contact lens shows that tear immunoglobulin rise accrues due to mechanical stimulation, hence contact lenses should not be used for a long period and lenses of hard nature should be discouraged. The maintenance, cleaning and deproteinization of the lenses are of high importance to avoid immunostimulation.

    1978-01-01

    We have, studied the effect of radiation on humoral immunity in patients with carcinoma of the cervix by measuring variations in serum immunoglobulins (IgA, IgG, IgM) during radiotherapy. Of 81 patients with untreated cancer of the cervix (at stages Ib-IIIb), those at stage III had a significantly lower IgG level (P < 0.05) compared with control patients (94 in number). There was a significant fall (P < 0.05) in the mean serum IgA and IgG levels during radiation therapy in group A (36 patients who received this modality of treatment alone). However, in group B (26 patients who underwent pelvic lymphadenectomy prior to radiotherapy) and in group C (9 patients subjected to hysterectomy with pelvic lymphadenectomy before irradiation) there was no significant fall in the mean serum IgA and IgG levels. There were two distinct patterns of variation in serum immunoglobulins seen during external irradiation: type a) in which serum immunoglobulin levels tended to decline with the increase in radiation dose, and type b) in which serum immunoglobulin levels either remained the same as those prior to irradiation or varied in an irregular fashion during irradiation. There was a significant difference (P < 0.05) in the incidence of either type a) or b) for IgG and IgM between group A and groups B and C. The type a) pattern of serum immunoglobulin variation was more common in patients with stage 1 carcinoma, and was gradually superceded by type b) in more advanced cases. Thus it would appear that lymph nodes retain the ability to respond to radiation in most cases of early stage carcinoma, but lose this capacity with more advanced carcinoma, a finding which is suggestive of lowered ability for antibody production of the most bearing advanced carcinoma.

  7. Intravenous Iron Carboxymaltose as a Potential Therapeutic in Anemia of Inflammation.

    Directory of Open Access Journals (Sweden)

    Niklas Lofruthe

    Full Text Available Intravenous iron supplementation is an effective therapy in iron deficiency anemia (IDA, but controversial in anemia of inflammation (AI. Unbound iron can be used by bacteria and viruses for their replication and enhance the inflammatory response. Nowadays available high molecular weight iron complexes for intravenous iron substitution, such as ferric carboxymaltose, might be useful in AI, as these pharmaceuticals deliver low doses of free iron over a prolonged period of time. We tested the effects of intravenous iron carboxymaltose in murine AI: Wild-type mice were exposed to the heat-killed Brucella abortus (BA model and treated with or without high molecular weight intravenous iron. 4h after BA injection followed by 2h after intravenous iron treatment, inflammatory cytokines were upregulated by BA, but not enhanced by iron treatment. In long term experiments, mice were fed a regular or an iron deficient diet and then treated with intravenous iron or saline 14 days after BA injection. Iron treatment in mice with BA-induced AI was effective 24h after iron administration. In contrast, mice with IDA (on iron deficiency diet prior to BA-IA required 7d to recover from AI. In these experiments, inflammatory markers were not further induced in iron-treated compared to vehicle-treated BA-injected mice. These results demonstrate that intravenous iron supplementation effectively treated the murine BA-induced AI without further enhancement of the inflammatory response. Studies in humans have to reveal treatment options for AI in patients.

    A controlled, randomised trial comparing the results of oral rehydration therapy with those of intravenous fluid treatment in 470 children with severe gastroenteritis was undertaken. The oral rehydration therapy was divided into two phases--a rehydration phase that used high sodium isotonic fluid at 40 ml/kg per hour and a maintenance phase using low sodium isotonic fluid (sodium 40, potassium 30, bicarbonate 25, chloride 45, and dextrose 130 mmol/l). The results indicate that oral rehydration treatment, used according to this protocol, is successful in treating severe diarrhoea and dehydration, and has considerable advantages over intravenous fluid therapy in reducing complications associated with the treatment of hypernatraemia, in promoting rapid correction of hypokalaemia and acidosis, in decreasing the duration of diarrhoea, and in promoting a greater weight gain at hospital discharge.

    Full Text Available The efficacy of florfenicol associated or not to intravenous fluid therapy for treatment of Salmonella Dublin-infected calves was determined. Twenty-four healthy 10 to 15-day-old Holstein calves were randomly allotted into four groups, with six animals each: control (group 1; infected with 10(8CFU Salmonella Dublin and not treated (group 2; infected with 10(8CFU Salmonella Dublin and treated with florfenicol (group 3; and infected with 10(8CFU Salmonella Dublin and treated with florfenicol associated to fluid therapy (group 4. All animals were submitted to physical examination just before inoculation and every 24 hours, during seven days after experimental infection. Rectal swabs and blood samples were collected for Salmonella Dublin isolation and pH and blood electrolytes determination. The experimental infection with Salmonella Dublin induced clinical signs of salmonellosis, such as diarrhea and fever, and caused reduction in blood concentrations of pH, sodium, potassium and chlorides. The treated calves showed good clinical recovery, and the group treated with antibiotic in combination to fluid therapy presented a faster and more efficient correction of the hydro-electrolyte balance.Avaliou-se a eficácia terapêutica do florfenicol associado ou não à fluidoterapia intravenosa no tratamento de bezerros infectados experimentalmente com Salmonella Dublin.

    2011-03-01

    The immunoglobulin λ isotype is present in nearly all vertebrates and plays an important role in the human immune system. Despite its importance, few systematic studies have been performed to analyze the structural conformation of its variable regions, contrary to what is the case for κ and heavy chains. We show here that an analysis of the structures of λ chains allows the definition of a discrete set of recurring conformations (canonical structures) of their hypervariable loops and, most importantly, the identification of sequence constraints that can be used to predict their structure. We also show that the structural repertoire of λ chains is different and more varied than that of the κ chains, consistently with the current view of the involvement of the two major light-chain families in complementary strategies of the immune system to ensure a fine tuning between diversity and stability in antigen recognition. © 2011 Wiley-Liss, Inc.

    32 patients with different tumours were irradiated by 60 Co gamma-rays. During therapy lasting for several weeks, changes in the content of immunoglobulin and of some other serum proteins, circulating immune complexes and plasma free hemoglobin were determined. Immunosuppression according to immunoglobulin content in serum was not produced by this type of radiation. Decrease in immune complex levels was a good prognostic sign. Low values of plasma hemoglobin content during treatment indicated that no erythrocyte membrane damage had been effected. (orig.) [de

    Orthopedic surgeons are becoming more involved in the care of patients with septic arthritis and bursitis caused by yeast species. This case report involves a middle-aged immunocompromised female who developed a Candida glabrata septic olecranon bursitis that developed after she received a corticosteroid injection in the olecranon bursa for presumed aseptic bursitis. Candida (Torulopsis) glabrata is the second most frequently isolated Candida species from the bloodstream in the United States. Increased use of fluconazole and other azole antifungal agents as a prophylactic treatment for recurrent Candida albicans infections in immunocompromised individuals is one reason why there appears to be increased resistance of C. glabrata and other nonalbicans Candida (NAC) species to fluconazole. In this patient, this infection was treated with surgery (bursectomy) and intravenous caspofungin, an echinocandin. This rare infectious etiology coupled with this intravenous antifungal treatment makes this case novel among cases of olecranon bursitis caused by yeasts.

    Full Text Available Serum immunoglobulins (IgG, IgA and IgM and immune complexes IgG (IcG were measured in 58 cases of acute inflammatory demyelinating neuropathy, popularly known as Guillian Barre′ syndrome, and in 30 healthy controls using single radial immunodiffusion assay. Immunoglobulin and immune complex levels were significantly elevated in patients as compared to controls. The increased levels of immunoglobulins and immune complexes may contribute to the pathogenesis of the disease and provide rationale for therapeutic plasmapheresis.

    Full Text Available 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.

    Full Text Available Intractable epilepsy in children poses a serious medical challenge. Acute repetitive seizures and status epilepticus leads to frequent emergency room visits and hospital admissions. Permanent neurological damage can occur if there is delay in treatment. It has been shown that these children continue to remain intractable even after acute seizure management with approved FDA agents. Intravenous levetiracetam, a second-generation anticonvulsant was approved by the FDA in 2006 in patients 16 years and older as an alternative when oral treatment is not an option. It has been shown that oral levetiracetam can be used in the treatment of status epilepticus and acute repetitive seizures. Data have been published showing that intravenous levetiracetam is safe and efficacious, and can be used in an acute inpatient setting. This current review will discuss the recent data about the safety and tolerability of intravenous levetiracetam in children and neonates, and emphasize the need for a larger prospective multicenter trial to prove the efficacy of this agent in acute seizure management.

    The recognition of the importance of Epstein-Barr virus (EBV) infection, including EBV-associated post-transplant lymphoproliferative disease (PTLD), has led to a new focus on the prevention of this problem. This paper reviews the scientific rationale behind, and clinical experience with, the use of chemoprophylaxis (using acyclovir or ganciclovir) and immunoprophylaxis (using intravenous immunoglobulin) in the prevention of EBV/PTLD. While some centers have already introduced the use of one or both of these agents as standard prophylaxis against the development of this complication, published data in support of these protocols are currently lacking. Well designed clinical trials are necessary to evaluate the potential role of both antiviral and immunoglobulin agents in the prevention of EBV/PTLD in organ transplant recipients.

    Full Text Available Background: Among hospitalized patients, indications for the measurement of magnesium levels and treatment of hypomagnesemia with intravenous magnesium are not well defined. Recently, there have been reports of worldwide shortages of intravenous magnesium sulphate. Objective: To examine secular trends in the administration of intravenous magnesium on hospital wards at a tertiary care institution. The secondary objective is to identify factors associated with magnesium use among admitted patients. Methods: Retrospective cross-section review of hospitalized patients at a single Canadian tertiary care center. Utilization of non-parental nutrition intravenous magnesium from 2003 to 2013 stratified by hospital ward was examined. In addition, patient level data from select wards (including medical and surgical services was examined at early and more recent time period (4/2006 versus 4/2013. Results: Among the 248,329 hospitalized patients, intravenous magnesium use increased by 2.86 fold from 2003 to 2013. Not all wards had an increase whereas some had nearly a 10 fold increase in use. In the sample ( n = 769, (adjusting for admission magnesium level, presence of an indication for intravenous magnesium, ward location, comorbidity and demographics intravenous magnesium administration was higher (25.8 % versus 5.5 % in 2013 versus 2006 (OR 13.91 (95 % CI, 6.21–31.17, p < 0.001. Despite this increase in intravenous magnesium administration, <3 % of patients were admitted on oral magnesium in 2006 and 2013. For patients receiving intravenous magnesium only a minority were discharged on oral therapy despite low levels. Conclusions: This center has witnessed a considerable increase in the use of in-hospital intravenous magnesium over the last 6 years that cannot be explained for by medical indications. The risks and benefits of this therapy deserve further study. If this change in practice is representative of other North American hospitals, it may be

However, successful venipuncture and intravenous cannulation are absolutely required for pediatric clinical risk management. This study assessed the success rate of venipuncture and intravenous cannulation when transmitted light was applied to the pediatric dorsum manus. The subjects included 100 young children who were scheduled for dental treatment or oral surgery under general anesthesia. Anesthesia was induced, and insertion of an intravenous catheter into the dorsum manus was attempted with or without using transmitted light. The patients were evaluated to determine whether the venipuncture was successful, and whether the intravenous cannulation of the external catheter was successful. The success rate of venipuncture was 100% when transmitted light was used, and 83% when the transmitted light was not used (P = 0.000016. In addition, the success rate of intravenous cannulation was 88% when transmitted light was used, and 55% when the transmitted light was not used (P = 0.0000002. The shape of the vein in the dorsum manus can be clearly recognized when transmitted light is used. The use of light significantly increased the success rate of intravenous cannulation, because it allowed direct confirmation of the direction to push the intravenous catheter forward. The use of transmitted light allows for more successful venipuncture and intravenous cannulation in young children.

JEV is considered to be indigenized and widespread in Japan, whereas WNV and DenV are not indigenized in Japan. Globulin products seem to reflect the status of the donor population according to antivirus neutralization activity. However, the anti-JEV, -WNV, and -DenV neutralization activities of globulin products derived from donors in Japan have not been clarified. Furthermore, potential candidates for the development of an effective immunotherapeutic drug for encephalitis caused by JEV, WNV, or DenV have also not been identified. Therefore, the aim of this study was to determine the overall status of the donor population in Japan based on globulin products by evaluating anti-JEV, -WNV, and -DenV neutralizing activities of intravenous immunoglobulin. Overall, intravenous immunoglobulin products showed stable neutralizing activity against JEV but showed no or only weak activity against WNV or DenV. These results suggest that the epidemiological level against WNV and DenV in the donor population of Japan is still low, suggesting that these viruses are not yet indigenized. In addition, JEV vaccinations and/or infections in the donor population do not induce a cross-reactive antibody against WNV. Keywords

  13. Immunoglobulin class-switch recombination deficiencies.

    2012-07-30

    Immunoglobulin class-switch recombination deficiencies (Ig-CSR-Ds) are rare primary immunodeficiencies characterized by defective switched isotype (IgG/IgA/IgE) production. Depending on the molecular defect in question, the Ig-CSR-D may be combined with an impairment in somatic hypermutation (SHM). Some of the mechanisms underlying Ig-CSR and SHM have been described by studying natural mutants in humans. This approach has revealed that T cell-B cell interaction (resulting in CD40-mediated signaling), intrinsic B-cell mechanisms (activation-induced cytidine deaminase-induced DNA damage), and complex DNA repair machineries (including uracil-N-glycosylase and mismatch repair pathways) are all involved in class-switch recombination and SHM. However, several of the mechanisms required for full antibody maturation have yet to be defined. Elucidation of the molecular defects underlying the diverse set of Ig-CSR-Ds is essential for understanding Ig diversification and has prompted better definition of the clinical spectrum of diseases and the development of increasingly accurate diagnostic and therapeutic approaches.

    Doxapram is a respiratory stimulant used to treat hypoventilation. Here we investigated whether doxapram could also trigger respiratory neuroplasticity. Specifically, we hypothesized that intermittent delivery of doxapram at low doses would lead to long-lasting increases (i.e., facilitation) of phrenic motor output in anesthetized, vagotomized, and mechanically-ventilated rats. Doxapram was delivered intravenously in a single bolus (2 or 6mg/kg) or as a series of 3 injections (2mg/kg) at 5min intervals. Control groups received pH-matched saline injections (vehicle) or no treatment (anesthesia time control). Doxapram evoked an immediate increase in phrenic output in all groups, but a persistent increase in burst amplitude only occurred after repeated dosing with 2mg/kg. At 60min following the last injection, phrenic burst amplitude was 168±24% of baseline (%BL) in the group receiving 3 injections (Pphrenic response to doxapram (2mg/kg) was reduced by 68% suggesting that at low doses the drug was acting primarily via the carotid chemoreceptors. We conclude that intermittent application of doxapram can trigger phrenic neuroplasticity, and this approach might be of use in the context of respiratory rehabilitation following neurologic injury. © 2013.

Human leukocyte antigen (HLA compatibility is an important tool to prevent post-transplant complications such as graft rejection and graft-versus-host disease, but the high rates of relapse limit the survival of transplant patients. Natural Killer cells, a type of lymphocyte that is a key element in the defense against tumor cells, cells infected with viruses and intracellular microbes, have different receptors on their surfaces that regulate their cytotoxicity. Killer immunoglobulin-like receptors are the most important, interacting consistently with human leukocyte antigen class I molecules present in other cells and thus controlling the activation of natural killer cells. Several studies have shown that certain combinations of killer immunoglobulin-like receptors and human leukocyte antigens (in both donors and recipients can affect the chances of survival of transplant patients, particularly in relation to the graft-versusleukemia effect, which may be associated to decreased relapse rates in certain groups. This review aims to shed light on the mechanisms and effects of killer immunoglobulin-like receptors - human leukocyte antigen associations and their implications following hematopoietic stem cell transplantation, and to critically analyze the results obtained by the studies presented herein.

    Full Text Available ABSTRACT: The aim of this study was to measure serum immunoglobulin concentrations of Nellore cattle produced by in vitro fertilization (IVF with umbilical diseases and to evaluate surgical excision as a method of treatment. Sixteen cattle with ages ranging from 1 to 15 months, males and females, affected by umbilical diseases were enrolled in the study. Blood samples were collected for cell counts and the determination of immunoglobulin concentrations by electrophoresis and zinc sulphate turbidimetry (ZST. Four calves were presented with umbilical herniation, two with an umbilical herniation associated with a persistent urachus, two with an umbilical herniation with a persistent urachus and omphaloarteritis, three with an umbilical herniation and an urachal diverticulum, three with a persistent urachus, one with an urachal diverticulum, and one with omphalitis. The blood cell counts pre- and post-surgical revealed differences in cell volume and the number of leukocytes. The immunoglobulin values measured by electrophoresis values were below normal in most animals, whereas the ZST showed normal levels in most of them. Most of the calves affected by umbilical diseases and produced by IVF presented hypoglobulinaemia. Correlations between umbilical diseases, failure of passive transfer of immunity and IVF could not be demonstrated.

    Reduced serum immunoglobulin (IgA, IgG, IgM) levels developed in the majority of 27 patients with hematologic disorders after treatment with 100 to 350 R total-body gamma-ray exposures at a dose rate of either 1.5 R/min to 1.5 R/hr. A reduction in IgA of 20 percent or more was found in 66 percent of the cases, while 56 percent showed an IgM decrease, and 49 percent an IgG decrease of 20 percent. The severity of immunoglobulin depression was influenced by the total radiation dose and the patient's primary disease. The occurrence of IgG and IgM depression was greater when the radiation was given at 1.5 R/hr than when the dose rate was 1.5 R/min. Substantial but incomplete recovery toward preirradiation immunoglobulin levels was found for most patients by 7 wk after total-body irradiation (TBI). (U.S.)

    The effects of 131 I therapy on the activity of thyroid stimulating antibody (TSAb) and thyrotrophin binding inhibiting immunoglobulin (TBII) in nineteen patients with Graves' disease have been studied. Prior to 131 I administration, TSAb was detected in 84%, and TBII in 68% of patients. Following 131 I administration TSAb and TBII were detectable in 100% of patients. The elevation 3 months after treatment of the means of both the TSAb and TBII indices for the group of nineteen patients was highly significant compared with pretreatment values. All the patients went into remission during the course of the study and the TSAb index declined in all patients, becoming undetectable in eleven; TBII also declined in most patients but remained detectable in thirteen. The study furthermore afforded the opportunity for a direct comparison of binding with stimulatory activity. These results show that after 131 I therapy for Graves' hyperthyroidism there is a transient increase in TSAb as well as TBII, followed by a decline, and that the measurement of binding and stimulatory activities are in good general agreement.

    2014-07-01

    A European reassessment has led to identical changes in the summaries of product characteristics (SPCs) for all intravenous iron-containing products: the risk of serious adverse effects is now highlighted, underlining the fact that intravenous iron-containing products should only be used when the benefits clearly outweigh the harms. Unfortunately, iron dextran still remains on the market despite a higher risk of hypersensitivity reactions than with iron sucrose.

    The introduction of intra-arterial chemotherapy (IAC) as salvage treatment has improved the prognosis for eye conservation in group D retinoblastoma. The aim of this study was to compare the outcomes of consecutive patients with advanced unilateral disease treated with either first-line intravenous chemotherapy (IVC) or first-line IAC. This is a retrospective mono-centric comparative review of consecutive patients. Sporadic unilateral retinoblastoma group D cases treated conservatively at Jules-Gonin Eye Hospital and CHUV between 1997 and 2014. From January 1997 to August 2008, IVC, combined with focal treatments, was the primary treatment approach. From September 2008 to October 2014, IAC replaced IVC as first-line therapy. 48 patients met the inclusion criteria, receiving only either IAC or IVC as primary treatment modality. Outcomes of 23 patients treated by IVC were compared with those of 25 treated by IAC; mean follow-up was 105.3 months (range 29.2-218.6) and 41.7 months (range 19.6-89.5), respectively. Treatment duration was significantly shorter in the IAC group (pchemotherapy treatment. Despite this, the results reported here imply that eyes treated with first-line IAC will have shorter treatment period, better ocular survival and visual acuity than first-line IVC.

  1. A new high molecular weight immunoglobulin class from the carcharhine shark: implications for the properties of the primordial immunoglobulin.

    1996-04-16

    All immunoglobulins and T-cell receptors throughout phylogeny share regions of highly conserved amino acid sequence. To identify possible primitive immunoglobulins and immunoglobulin-like molecules, we utilized 3' RACE (rapid amplification of cDNA ends) and a highly conserved constant region consensus amino acid sequence to isolate a new immunoglobulin class from the sandbar shark Carcharhinus plumbeus. The immunoglobulin, termed IgW, in its secreted form consists of 782 amino acids and is expressed in both the thymus and the spleen. The molecule overall most closely resembles mu chains of the skate and human and a new putative antigen binding molecule isolated from the nurse shark (NAR). The full-length IgW chain has a variable region resembling human and shark heavy-chain (VH) sequences and a novel joining segment containing the WGXGT motif characteristic of H chains. However, unlike any other H-chain-type molecule, it contains six constant (C) domains. The first C domain contains the cysteine residue characteristic of C mu1 that would allow dimerization with a light (L) chain. The fourth and sixth domains also contain comparable cysteines that would enable dimerization with other H chains or homodimerization. Comparison of the sequences of IgW V and C domains shows homology greater than that found in comparisons among VH and C mu or VL, or CL thereby suggesting that IgW may retain features of the primordial immunoglobulin in evolution.

    Full Text Available Context: Chronic inflammatory demyelinating polyradiculopathy (CIDP is an acquired and autoimmune neuropathy, characterized by a chronic, rapidly progressive, symmetric weakness. In children, abnormal gait is as a first symptom of muscle weakness. Evidence Acquisition: The diagnosis of CIDP is on the basis of clinical characteristics, electrodiagnostic that shows the severity of the disease, lumbar puncture and spine magnetic resonance imaging (MRI. Results: The first-line treatments in childhood CIDP are intravenous immunoglobulin (IVIG, corticosteroids, and plasmapheresis. Response to first-line therapies is usually satisfactory; nevertheless, recommendations regarding the choice of second-line therapy can only be prepared on the basis of the existing practice described in some of the case reports. Conclusions: This review demonstrated the clinical presentation, diagnosis, and treatment of childhood CIDP.

  4. Immunoglobulin heavy chain exclusion in the shark.

    Full Text Available The adaptive immune system depends on specific antigen receptors, immunoglobulins (Ig in B lymphocytes and T cell receptors (TCR in T lymphocytes. Adaptive responses to immune challenge are based on the expression of a single species of antigen receptor per cell; and in B cells, this is mediated in part by allelic exclusion at the Ig heavy (H chain locus. How allelic exclusion is regulated is unclear; we considered that sharks, the oldest vertebrates possessing the Ig/TCR-based immune system, would yield insights not previously approachable and reveal the primordial basis of the regulation of allelic exclusion. Sharks have an IgH locus organization consisting of 15-200 independently rearranging miniloci (VH-D1-D2-JH-Cmu, a gene organization that is considered ancestral to the tetrapod and bony fish IgH locus. We found that rearrangement takes place only within a minilocus, and the recombining gene segments are assembled simultaneously and randomly. Only one or few H chain genes were fully rearranged in each shark B cell, whereas the other loci retained their germline configuration. In contrast, most IgH were partially rearranged in every thymocyte (developing T cell examined, but no IgH transcripts were detected. The distinction between B and T cells in their IgH configurations and transcription reveals a heretofore unsuspected chromatin state permissive for rearrangement in precursor lymphocytes, and suggests that controlled limitation of B cell lineage-specific factors mediate regulated rearrangement and allelic exclusion. This regulation may be shared by higher vertebrates in which additional mechanistic and regulatory elements have evolved with their structurally complex IgH locus.

  5. Manufacture of immunoglobulin products for patients with primary antibody deficiencies – the effect of processing conditions on product safety and efficacy

    2014-12-01

    Full Text Available Early preparations of immunoglobulin (IG manufactured from human plasma by ethanol (Cohn fractionation were limited in their usefulness for substitution therapy in patients with primary antibody deficiencies (PAD, as IG aggregates formed during manufacture resulted in severe systemic reactions in patients when given intravenously. Developments in manufacturing technology obviated this problem through the capacity to produce concentrated solutions of intact monomeric IG, revolutionizing PAD treatment and improving patient life expectancy and quality of life. As the need for IG has grown, manufacturers have refined further manufacturing technologies to improve yield from plasma and produce therapies which are easier and less expensive to deliver. This has led to the substitution, partly or wholly, of ethanol precipitation by other techniques such as chromatography, and has also stimulated the production of highly concentrated solutions capable of rapid infusion. IG products have been associated, since their inception, with certain adverse events, including infectious disease transmission, haemolysis and thromboembolism. The introduction of standardized manufacturing processes and dedicated pathogen elimination steps has removed the risk of infectious disease, and the focus of attention has shifted to other problems which appear to have increased over the past five years. These include haemolysis and thromboembolism, both the cause for substantial concern and the subject of recent regulatory scrutiny and actions. We review the development of manufacturing technology and the emerging evidence that changes for the optimization of yield and convenience has contributed to the recent incidents in certain adverse events. Industry measures under development will be discussed in terms of their potential to improve safety and optimize care for patients with PAD.

Physicians should keep in mind that patients with Graves' disease may show thyroid-stimulating hormone-binding inhibitory immunoglobulin assay results that do not reflect the severity of Graves' disease or indicate the outcome of the disease, and that active Graves' disease may persist even after negative results on thyroid-stimulating hormone-binding inhibitory immunoglobulin assays. Timely performance of thyroid function tests in combination with sensitive imaging tests, including thyroid ultrasound and scintigraphy, are necessary to evaluate the severity of Graves' disease and treatment efficacy.

  7. Why intravenous moderate sedation should be taught in graduate endodontic programs.

    Montagnese, Thomas Anthony

    2012-03-01

    The purpose of this opinion article is to present reasons why intravenous moderate sedation should be taught in graduate endodontic programs. Access to oral health care is an area of much interest and concern, but some patients are unable to get endodontic care because they have special needs. Special needs can refer to patients who fear dentistry itself and other aspects of dental treatment. A variety of phobias and medical, developmental, and physical conditions can make it difficult for some patients to tolerate the endodontic care they need and want. Moderate sedation can help many of these patients. Endodontists in general are not trained to provide intravenous moderate sedation. By incorporating intravenous moderate sedation into endodontic practice, many of these patients can be treated. The first step in achieving this goal is to add intravenous moderate sedation training to graduate endodontic programs. The long-term effect will be to make specialty endodontic care available to more people.

    We tested biweekly infusions of IV immunoglobulin (IVIg) as a possible treatment for mild to moderate Alzheimer disease (AD) dementia. In a phase 3, double-blind, placebo-controlled trial, we randomly assigned 390 participants with mild to moderate AD to receive placebo (low-dose albumin) or IVIg (Gammagard Liquid; Baxalta, Bannockburn, IL) administered IV at doses of 0.2 or 0.4 g/kg every 2 weeks for 18 months. The primary cognitive outcome was change from baseline to 18 months on the 11-item cognitive subscale of the Alzheimer's Disease Assessment Scale; the primary functional outcome was 18-month change on the Alzheimer's Disease Cooperative Study-Activities of Daily Living Inventory. Safety and tolerability data, as well as serial MRIs and plasma samples, were collected throughout the study from all enrolled participants. No beneficial effects were observed in the dual primary outcome measures for the 2 IVIg doses tested. Significant decreases in plasma Aβ42 (but not Aβ40) levels were observed in IVIg-treated participants. Analysis of safety data showed no difference between IVIg and placebo in terms of the rate of occurrence of amyloid-related imaging abnormalities (brain edema or microhemorrhage). IVIg-treated participants had more systemic reactions (chills, rashes) but fewer respiratory infections than participants receiving placebo. Participants with mild to moderate AD showed good tolerability of treatment with low-dose human IVIg for 18 months but did not show beneficial effects on cognition or function relative to participants who received placebo. NCT00818662. This study provides Class II evidence that IVIg infusions performed every 2 weeks do not improve cognition or function at 18 months in patients with mild to moderate AD. © 2017 American Academy of Neurology.

    Full Text Available Therapeutic human polyclonal antibodies (hpAbs derived from pooled plasma from human donors are Food and Drug Administration approved biologics used in the treatment of a variety of human diseases. Powered by the natural diversity of immune response, hpAbs are effective in treating diseases caused by complex or quickly-evolving antigens such as viruses. We previously showed that transchromosomic (Tc cattle carrying a human artificial chromosome (HAC comprising the entire unrearranged human immunoglobulin heavy-chain (hIGH and kappa-chain (hIGK germline loci (named as κHAC are capable of producing functional hpAbs when both of the bovine immunoglobulin mu heavy-chains, bIGHM and bIGHML1, are homozygously inactivated (double knockouts or DKO. However, B lymphocyte development in these Tc cattle is compromised, and the overall production of hpAbs is low. Here, we report the construction of an improved HAC, designated as cKSL-HACΔ, by incorporating all of the human immunoglobulin germline loci into the HAC. Furthermore, for avoiding the possible human-bovine interspecies incompatibility between the human immunoglobulin mu chain protein (hIgM and bovine transmembrane α and β immunoglobulins (bIgα and bIgβ in the pre-B cell receptor (pre-BCR complex, we partially replaced (bovinized the hIgM constant domain with the counterpart of bovine IgM (bIgM that is involved in the interaction between bIgM and bIgα/Igβ; human IgM bovinization would also improve the functionality of hIgM in supporting B cell activation and proliferation. We also report the successful production of DKO Tc cattle carrying the cKSL-HACΔ (cKSL-HACΔ/DKO, the dramatic improvement of B cell development in these cattle and the high level production of hpAbs (as measured for the human IgG isotype in the plasma. We further demonstrate that, upon immunization by tumor immunogens, high titer tumor immunogen-specific human IgG (hIgG can be produced from such Tc cattle.

    The prognostic value of minimal residual disease (MRD) in Philadelphia-chromosome-positive (Ph+) childhood acute lymphoblastic leukemia (ALL) treated with tyrosine kinase inhibitors is not fully established. We detected MRD by real-time quantitative polymerase chain reaction (RQ-PCR) of rearranged immunoglobulin/T-cell receptor genes (IG/TR) and/or BCR/ABL1 fusion transcript to investigate its predictive value in patients receiving Berlin-Frankfurt-Münster (BFM) high-risk (HR) therapy and post-induction intermittent imatinib (the European intergroup study of post-induction treatment of Philadelphia-chromosome-positive acute lymphoblastic leukemia (EsPhALL) study). MRD was monitored after induction (time point (TP)1), consolidation Phase IB (TP2), HR Blocks, reinductions, and at the end of therapy. MRD negativity progressively increased over time, both by IG/TR and BCR/ABL1. Of 90 patients with IG/TR MRD at TP1, nine were negative and none relapsed, while 11 with MRD<5×10−4 and 70 with MRD≥5×10−4 had a comparable 5-year cumulative incidence of relapse of 36.4 (15.4) and 35.2 (5.9), respectively. Patients who achieved MRD negativity at TP2 had a low relapse risk (5-yr cumulative incidence of relapse (CIR)=14.3[9.8]), whereas those who attained MRD negativity at a later date showed higher CIR, comparable to patients with positive MRD at any level. BCR/ABL1 MRD negative patients at TP1 had a relapse risk similar to those who were IG/TR MRD negative (1/8 relapses). The overall concordance between the two methods is 69%, with significantly higher positivity by BCR/ABL1. In conclusion, MRD monitoring by both methods may be functional not only for measuring response but also for guiding biological studies aimed at investigating causes for discrepancies, although from our data IG/TR MRD monitoring appears to be more reliable. Early MRD negativity is highly predictive of favorable outcome. The earlier MRD negativity is achieved, the better the prognosis. PMID

    Intravenous access in prehospital emergency care allows for early administration of medication and extended measures such as anaesthesia. Cannulation may, however, be difficult, and failure and resulting delay in treatment and transport may have negative effects on the patient. Therefore, our study aims to perform a concise assessment of the difficulties of prehospital venous cannulation. We analysed 23 candidate predictor variables on peripheral venous cannulations in terms of cannulation failure and exceedance of a 2 min time threshold. Multivariate logistic regression models were fitted for variables of predictive value (P0.6) of their respective receiver operating characteristic curve. A total of 762 intravenous cannulations were enroled. In all, 22% of punctures failed on the first attempt and 13% of punctures exceeded 2 min. Model selection yielded a three-factor model (vein visibility without tourniquet, vein palpability with tourniquet and insufficient ambient lighting) of fair accuracy for the prediction of puncture failure (AUC=0.76) and a structurally congruent model of four factors (failure model factors plus vein visibility with tourniquet) for the exceedance of the 2 min threshold (AUC=0.80). Our study offers a simple assessment to identify cases of difficult intravenous access in prehospital emergency care. Of the numerous factors subjectively perceived as possibly exerting influences on cannulation, only the universal - not exclusive to emergency care - factors of lighting, vein visibility and palpability proved to be valid predictors of cannulation failure and exceedance of a 2 min threshold.

    (PDA in extremely low birth weight (ELBW infants. Oral ibuprofen was compared to intravenous indomethacin regarding efficacy and safety in the treatment of PDA in infants weighting less than 1,000 g at birth. METHOD: This was a retrospective study in a single center. Data on ELBW infants who had an echocardiographically confirmed PDA were collected. The infants were treated with either intravenous indomethacin or oral ibuprofen. Rate of ductal closure, need for additional treatment, drug-related side effects or complications, and mortality were compared between the two treatment groups. RESULT: 26 infants who received indomethacin and 22 infants who received ibuprofen were studied. The overall rate of ductal closure was similar between the two treatments: it occurred in 23 of 26 infants (88.5% treated with indomethacin, and in 18 of 22 infants (81.8% treated with ibuprofen (p = 0.40. The rate of surgical ligation (11.5% versus 18.2%; p = 0.40 did not differ significantly between the two treatment groups. No significant difference was found in post-treatment serum creatinine concentrations between the two groups. There were no significant differences regarding additional side effects or complications. CONCLUSION: In ELBW infants, oral ibuprofen is as efficacious as intravenous indomethacin for the treatment of PDA. There were no differences between the two drugs with respect to safety. Oral ibuprofen could be used as an alternative agent for the treatment of PDA in ELBW infants.

    Immunoglobulin G4 (IgG4)-related disease is a well-known disorder characterized by an inflammatory reaction with an increase in the number of IgG4-positive plasma cells associated with sclerosis. IgG4-related disease often affects the dura mater with a pattern of diffuse thickening when the central nervous system is involved. However, some nodular dural thickening requires discrimination from tumors because of obviously different treatment options. We report of a case of IgG4-related disease with tumefactive dural involvement

    To estimate whether treatment with intravenous nitroglycerin for uterine relaxation increases the chance of successful external cephalic version. Two double-blind, randomized clinical trials were undertaken: one in nulliparous women and a second in multiparous women. Women presenting for external cephalic version at term were eligible to participate. The primary outcome was immediate success of external cephalic version. Other outcomes were presentation at delivery, cesarean delivery rate, and side effects and complications. Sample size calculations were based on a 100% increase in success of external cephalic version with a one-sided analysis and alpha=0.05 (80% power). In total, 126 women were recruited-82 in the nulliparous trial and 44 in the multiparous trial. Seven patients did not have external cephalic version before delivery but were included in the analysis of success of external cephalic version. One patient was lost to follow-up. The external cephalic version success rate for nulliparous patients was 24% (10 of 42) in patients who received nitroglycerin compared with 8% (3 of 40) in those who receive placebo (P=.04, one-sided Fisher exact test, odds ratio 3.85, lower bound 1.22). In multiparous patients, the external cephalic version success rate did not differ significantly between groups: 44% (10 of 23) in the nitroglycerin group compared with 43% (9 of 21) in the placebo group (P=.60). Treatment with intravenous nitroglycerin increased the rate of successful external cephalic version in nulliparous, but not in multiparous, women. Treatment with intravenous nitroglycerin appeared to be safe, but our numbers were too small to rule out rare serious adverse effects. I.

  18. [Peripheral intravenous catheter-related phlebitis].

    2011-01-01

    Phlebitis is a very common complication of the use of intravenous catheters. Two patients with an i.v. catheter complicated by thrombophlebitis are described. Patient A was immunocompromised due to chronic lymphatic leukaemia and developed septic thrombophlebitis with positive blood cultures for S. Aureus. Patient B was being treated with flucloxacillin because of an S. Aureus infection and developed chemical phlebitis. Septic phlebitis is rare, but potentially serious. Chemical or mechanical types of thrombophlebitis are usually less severe, but happen very frequently. Risk factors include: female sex, previous episode of phlebitis, insertion at (ventral) forearm, emergency placement and administration of antibiotics. Until recently, routine replacement of peripheral intravenous catheters after 72-96 h was recommended, but randomised controlled trials have not shown any benefit of this routine. A recent Cochrane Review recommends replacement of peripheral intravenous catheters when clinically indicated only.

    Heat-inactivated normal human serum produces iron-reversible bacteriostasis of a number of microorganisms. This inhibitory effect was abolished by adsorption of serum with ultraviolet-killed cells of species that produce the siderophore enterochelin. Bacteriostasis also was alleviated by asorption of serum with 2,3-dihydroxy-N-benzoyl-L-serine, a degradation product of enterochelin, bound to the insoluble matrix AH-Sepharose 4B. Our results indicate that enterochelin-specific immunoglobulins exist in normal human serum. These immunoglobulins may act synergistically with transferrin to effect bacteriostasis of enterochelin-producing pathogens.

    Full Text Available Mepivacaine is a potent local anaesthetic and used for infiltration and regional anaesthesia in adults and pediatric patients. Intoxications with mepivacaine affect mainly the CNS and the cardiovascular system. We present a case of accidental intravenous mepivacaine application and intoxication of an infant resulting in seizure, broad complex bradyarrhythmia, arterial hypotension and finally cardiac arrest. The patient could be rescued by prolonged resuscitations and a rapid initiation of ECMO and survived without neurological damage. The management strategies of this rare complication including promising other treatment options with lipid emulsions are discussed.

    Ten healthy volunteers received three standard Bier's blocks. Prilocaine 0.5%, 40 ml was injected at a solution temperature of 0 degrees C, 22 degrees C or 37 degrees C. Recordings were made of sensory block, motor block, intravenous pressure, limb temperature and pain on injection. There were no differences between the three treatments in the rate of development or in the quality of block but there was a significant difference in the comfort of injection. Cold solutions caused most, and warm solutions least discomfort.

  2. A Phase 3, Randomized, Double-Blind, Multicenter Study to Evaluate the Safety and Efficacy of Intravenous Iclaprim Vs Vancomycin for the Treatment of Acute Bacterial Skin and Skin Structure Infections Suspected or Confirmed to be Due to Gram-Positive Pathogens: REVIVE-1.

    Our objective in this study was to demonstrate the safety and efficacy of iclaprim compared with vancomycin for the treatment of patients with acute bacterial skin and skin structure infections (ABSSSIs). REVIVE-1 was a phase 3, 600-patient, double-blinded, randomized (1:1), active-controlled trial among patients with ABSSSI that compared the safety and efficacy of iclaprim 80 mg fixed dose with vancomycin 15 mg/kg, both administered intravenously every 12 hours for 5-14 days. The primary endpoint of this study was a ≥20% reduction in lesion size (early clinical response [ECR]) compared with baseline among patients randomized to iclaprim or vancomycin at the early time point (ETP), 48 to 72 hours after the start of administration of study drug in the intent-to-treat population. ECR among patients who received iclaprim and vancomycin at the ETP was 80.9% (241 of 298) of patients receiving iclaprim compared with 81.0% (243 of 300) of those receiving vancomycin (treatment difference, -0.13%; 95% confidence interval, -6.42%-6.17%). Iclaprim was well tolerated in the study, with most adverse events categorized as mild. Iclaprim achieved noninferiority (10% margin) at ETP compared with vancomycin and was well tolerated in this phase 3 clinical trial for the treatment of ABSSSI. Based on these results, iclaprim appears to be an efficacious and safe treatment for ABSSSI suspected or confirmed to be due to gram-positive pathogens. NCT02600611.

    Full Text Available In order to obtain intravenous immunoglobulin G (iv IgG of high quality from F-I+II+III or F-II+III pastes prepared by the Cohn method, we developed a chromatography process using ion exchange gels, Q-Sepharose FF and CM-Sepharose FF, and Sephacryl S-300 gel filtration. Viral inactivation was performed by incubating the preparation with pepsin at pH 4.0 at 35oC for 18 h. The characteristics of 28 batches produced by us were: yield 4.3 ± 0.2 g/l plasma, i.e., a recovery of 39.1 ± 1.8%; IgG subclasses distribution: IgG1 = 58.4%, IgG2 = 34.8%, IgG3 = 4.5% and IgG4 = 2.3%; IgG size distribution was 98.4% monomers, 1.2% dimers and 0.4% polymers and protein aggregates; anticomplement activity was less than 0.5 CH50/mg IgG, and prekallikrein activator activity (PKA was less than 5 IU/ml. These characteristics satisfied the requirements of the European Pharmacopoea edition, and the regulations of the Brazilian Health Ministry (M.S. Portaria No. 2, 30/10/1998.

    The aim of this study was to clarify whether Tc-99m HIG (Polyclonal Human Immunoglobulin G) can image and determine the severity of orbital involvement in patients with Graves' ophthalmopathy. Twenty-six patients between 19 and 56 years old with Graves' ophthalmopathy were examined. All patients received approximately 370 MBq Tc-99m HIG by intravenous (i.v.) injection. Planar and SPECT examination were performed 4 hours after the injection. Visual and semiquantitative evaluations were performed for both orbits by two independent observers. Clinically active ophthalmopathy patients had noticeably increased orbital accumulation of Tc-99m HIG. In patients with inactive disease, and 14 of 19 had no uptake, whereas 5 patients had orbital radioactivity accumulation. The duration of Graves' ophthalmopathy did not correlate with the presence of active ophthalmopathy and Tc-99m HIG grade. There was no correlation between clinical classification and clinical activity (r=278). There was a good correlation between clinical activity and the radioactivity grade with r=0.666 (p=0.01). The clinical classification closely correlated with Tc-99m HIG grade (r=0.423, p=0.05) Tc-99m HIG scan can clearly identified clinically active patients, and subclinical inflammation can be shown by this scintigraphic evaluation. The current preliminary results suggested that Tc-99m HIG SPECT might be useful for the assessment of disease activity in Graves' ophthalmopathy. (author)

  5. Specific egg yolk immunoglobulin as a new preventive approach for Shiga-toxin-mediated diseases.

    Paola Neri

    Full Text Available Shiga toxins (Stxs are involved in the development of severe systemic complications associated with enterohemorrhagic Escherichia coli (EHEC infection. Various neutralizing agents against Stxs are under investigation for management of EHEC infection. In this study, we immunized chickens with formalin-inactivated Stx-1 or Stx-2, and obtained immunoglobulin Y (IgY from the egg yolk. Anti-Stx-1 IgY and anti-Stx-2 IgY recognized the corresponding Stx A subunit and polymeric but not monomeric B subunit. Anti-Stx-1 IgY and anti-Stx-2 IgY suppressed the cytotoxicity of Stx-1 and Stx-2 to HeLa 229 cells, without cross-suppressive activity. The suppressive activity of these IgY was abrogated by pre-incubation with the corresponding recombinant B subunit, which suggests that the antibodies directed to the polymeric B subunits were predominantly involved in the suppression. In vivo, the intraperitoneal or intravenous administration of these IgY rescued mice from death caused by intraperitoneal injection of the corresponding toxin at a lethal dose. Moreover, oral administration of anti-Stx-2 IgY reduced the mortality of mice infected intestinally with EHEC O157:H7. Our results therefore suggest that anti-Stx IgY antibodies may be considered as preventive agents for Stx-mediated diseases in EHEC infection.

    Full Text Available Secondary antibody deficiency can occur as a result of haematological malignancies or certain medications, but not much is known about the clinical and immunological features of this group of patients as a whole. Here we describe a cohort of 167 patients with primary or secondary antibody deficiencies on immunoglobulin (Ig-replacement treatment. The demographics, causes of immunodeficiency, diagnostic delay, clinical and laboratory features, and infection frequency were analysed retrospectively. Chemotherapy for B cell lymphoma and the use of Rituximab, corticosteroids or immunosuppressive medications were the most common causes of secondary antibody deficiency in this cohort. There was no difference in diagnostic delay or bronchiectasis between primary and secondary antibody deficiency patients, and both groups experienced disorders associated with immune dysregulation. Secondary antibody deficiency patients had similar baseline levels of serum IgG, but higher IgM and IgA, and a higher frequency of switched memory B cells than primary antibody deficiency patients. Serious and non-serious infections before and after Ig-replacement were also compared in both groups. Although secondary antibody deficiency patients had more serious infections before initiation of Ig-replacement, treatment resulted in a significant reduction of serious and non-serious infections in both primary and secondary antibody deficiency patients. Patients with secondary antibody deficiency experience similar delays in diagnosis as primary antibody deficiency patients and can also benefit from immunoglobulin-replacement treatment.

    Secondary antibody deficiency can occur as a result of haematological malignancies or certain medications, but not much is known about the clinical and immunological features of this group of patients as a whole. Here we describe a cohort of 167 patients with primary or secondary antibody deficiencies on immunoglobulin (Ig)-replacement treatment. The demographics, causes of immunodeficiency, diagnostic delay, clinical and laboratory features, and infection frequency were analysed retrospectively. Chemotherapy for B cell lymphoma and the use of Rituximab, corticosteroids or immunosuppressive medications were the most common causes of secondary antibody deficiency in this cohort. There was no difference in diagnostic delay or bronchiectasis between primary and secondary antibody deficiency patients, and both groups experienced disorders associated with immune dysregulation.

    Full Text Available Background. Traditional mistletoe therapy in cancer patients involves subcutaneous applications of Viscum album L. preparations, with doses slowly increasing based on patient responses. Intravenous infusion of high doses may improve therapeutic outcomes and is becoming more common. Little is known about the safety of this “off-label” application of mistletoe. Methods. An observational study was performed within the Network Oncology. Treatment with intravenous mistletoe applications is described. The frequency of adverse drug reactions (ADRs to intravenous mistletoe applications was calculated and compared to ADR data from a study on subcutaneous applications. Results. Of 475 cancer patients who received intravenous infusions of Helixor, Abnoba viscum, or Iscador mistletoe preparations, 22 patients (4.6% reported 32 ADRs of mild (59.4% or moderate severity (40.6%. No serious ADRs occurred. ADRs were more frequently reported to i.v. mistletoe administered alone (4.3%, versus prior to chemotherapy (1.6%. ADR frequency differed with respect to preparation type, with Iscador preparations showing a higher relative frequency, compared to Abnoba viscum and Helixor. Overall, patients were almost two times less likely to experience an ADR to intravenous compared to subcutaneous application of mistletoe. Conclusion. Intravenous mistletoe therapy was found to be safe and prospective studies for efficacy are recommended.

    Bioelectrical impedance (BIA) is often used to measure body fluid spaces and thereby body composition. However, in acute animal studies, we found that impedance was driven by the saline content of intravenous (IV) fluids and not by the volume. The aim of the study was to investigate the effect of 3 different fluids acutely administered on the change in impedance, specifically resistance (R). Nine healthy adults participated in 3 treatment (0.9% saline, 5% dextrose, and a mixture of 0.3% saline + 3.3% dextrose) experiments on nonconsecutive days. They all received 1 L of one of the treatments intravenously over a 1-hour period. Repeated BIA measurements were performed prior to IV infusion and then every 5 minutes for the 1-hour infusion period, plus 3 more measurements up to 15 minutes after the completion of the infusion. The change in R in the 0.9% saline infusion experiment was significantly lower than that of the glucose and mixture treatment ( P < .001). Bioelectrical impedance spectroscopy and BIA measure salt rather than the volume changes over the infusion period. Hence, in patients receiving IV fluids, BIA of any kind (single frequency or multifrequency) cannot be used to measure body fluid spaces or body composition.

    Full Text Available BACKGROUND: With a wide range of applications, titanium dioxide (TiO₂ nanoparticles (NPs are manufactured worldwide in large quantities. Recently, in the field of nanomedicine, intravenous injection of TiO₂ nanoparticulate carriers directly into the bloodstream has raised public concerns on their toxicity to humans. METHODS: In this study, mice were injected intravenously with a single dose of TiO₂ NPs at varying dose levels (0, 140, 300, 645, or 1387 mg/kg. Animal mortality, blood biochemistry, hematology, genotoxicity and histopathology were investigated 14 days after treatment. RESULTS: Death of mice in the highest dose (1387 mg/kg group was observed at day two after TiO₂ NPs injection. At day 7, acute toxicity symptoms, such as decreased physical activity and decreased intake of food and water, were observed in the highest dose group. Hematological analysis and the micronucleus test showed no significant acute hematological or genetic toxicity except an increase in the white blood cell (WBC count among mice 645 mg/kg dose group. However, the spleen of the mice showed significantly higher tissue weight/body weight (BW coefficients, and lower liver and kidney coefficients in the TiO₂ NPs treated mice compared to control. The biochemical parameters and histological tissue sections indicated that TiO₂ NPs treatment could induce different degrees of damage in the brain, lung, spleen, liver and kidneys. However, no pathological effects were observed in the heart in TiO₂ NPs treated mice. CONCLUSIONS: Intravenous injection of TiO₂ NPs at high doses in mice could cause acute toxicity effects in the brain, lung, spleen, liver, and kidney. No significant hematological or genetic toxicity was observed.

    Emergency Department (ED) headache patients are commonly treated with neuroleptic antiemetics like metoclopramide. Haloperidol has been shown to be effective for migraine treatment. Our study compared the use of metoclopramide vs. haloperidol to treat ED migraine patients. A prospective, double-blinded, randomized control trial of 64 adults aged 18-50 years with migraine headache and no recognized risks for QT-prolongation. Haloperidol 5 mg or metoclopramide 10 mg was given intravenously after 25 mg diphenhydramine. Pain, nausea, restlessness (akathisia), and sedation were assessed with 100-mm visual analog scales (VAS) at baseline and every 20 min, to a maximum of 80 min. The need for rescue medications, side effects, and subject satisfaction were recorded. QTc intervals were measured prior to and after treatment. Follow-up calls after 48 h assessed satisfaction and recurrent or persistent symptoms. Thirty-one subjects received haloperidol, 33 metoclopramide. The groups were similar on all VAS measurements, side effects, and in their satisfaction with therapy. Pain relief averaged 53 mm VAS over both groups, with equal times to maximum improvement. Subjects receiving haloperidol required rescue medication significantly less often (3% vs. 24%, p haloperidol-treated subjects experiencing more restlessness (43% vs. 10%). Intravenous haloperidol is as safe and effective as metoclopramide for the ED treatment of migraine headaches, with less frequent need for rescue medications. Published by Elsevier Inc.

    Although molds are regarded as the main fungal allergen sources, evidence indicates that spores of Basidiomycota including Agaricus bisporus ( A. bisporus ) can be also found at high concentrations in the environment and may cause as many respiratory allergies as molds. The aim of the present study was to evaluate specific immunoglobulin E (IgE) and immunoglobulin G (IgG) antibodies against A. bisporus via immunoblotting technique in individuals working at mushroom cultivation centers. In this study, 72 workers involved in the cultivation and harvest of button mushrooms were enrolled. For the analysis of serum IgE and IgG, A. bisporus grown in Sabouraud dextrose broth was harvested and ruptured by liquid nitrogen and glass beads. The obtained sample was centrifuged and the supernatant was collected as "crude extract" (CE). CE was separated via Sodium Dodecyl Sulfate-Polyacrylamide Gel Electrophoresis (SDS-PAGE). The separated proteins were transferred to a nitrocellulose filter and the bands responsive to IgE and IgG were identified by anti-human conjugated antibodies. All participants were screened in terms of total IgE level. Among 72 workers, 18 (25%) had a total IgE level higher than 188 IU/mL. In SDS-PAGE, the CE of A. bisporus showed 23 different protein bands with a molecular weight range of 13-80 kDa. The sera of 23.6% and 55.5% of participants showed positive response, with specific IgE and IgG antibodies against A. bisporus in the blot, respectively. The bands with molecular weights of 62 and 68 kDa were the most reactive protein components of A. bisporus to specific IgE antibodies. Moreover, bands with molecular weights of 57 and 62 kDa showed the highest reactivity to IgG, respectively. Also, 62 and 68 kDa components were the most reactive bands with both specific IgG and IgE antibodies. The obtained findings revealed that A. bisporus has different allergens and antigens, which contribute to its potential as an aeroallergen in hypersensitivity
