    Undifferentiated arthritis (UA) is a frequently occurring clinical presentation with a variable outcome. While some forms of UA will spontaneously remit, other forms will progress to chronic arthritis; an outcome that would preferably be prevented. Which immunological factors are normally at the basis of resolution of inflammation, and what, on the other hand, causes inflammation to persist? This review provides an overview of the immunological mechanisms involved in these two scenarios, including specific examples of how these mechanisms apply, or can be influenced in rheumatic diseases. Furthermore, what do we know about risk factors for chronic arthritis, such as the development of autoantibodies? The recent years have provided many insights concerning risk factors for autoantibody-positive versus autoantibody-negative rheumatoid arthritis, which are discussed along with a possible pathophysiological model incorporating autoantibodies into the larger process of disease development. Finally, the evolution of the autoantibody response over time is described.

    About 20% of patients with juvenile chronic arthritis develop uveitis which is frequently bilateral. Risk factors for uveitis are: female gender, pauciarticular onset of arthritis, presence of circulating antinuclear antibodies, and the antigens HLA-DW5 and HLA-DPw2. The visual prognosis in patients with uveitis is good in 25% and fair in 50%. The remaining 25% develop cataract and/or glaucoma. The management of glaucoma is unsatisfactory, but the results of cataract surgery by lensectomy are good.

    The nomenclature and classification criteria for arthritis in children should be dealt with initially as separate issues, although they are undoubtedly intertwined. The classification criteria should aim to delineate homogeneous patient populations, yet should be flexible enough to incorporate advances in disease knowledge. It should be recognized that arriving at an international consensus for classification criteria will merely provide a set of operational definitions to facilitate research, and not a set of diagnostic criteria. Indeed the only point to obtaining consensus is to begin a process of systematic ongoing review of the criteria. The labels attached to any of these diseases should facilitate accurate communication. In view of the heterogeneous nature of childhood arthritis, consideration should be given to using a broad umbrella term such as juvenile or childhood arthritis only for communicating with the lay public. Medical nomenclature should be formulated to reflect accurately homogeneous subgroups of arthritis, and should not artificially proscribe a relationship between paediatric and adult disease.

    Full Text Available Abstract Background and aim Marine n-3 fatty acids and γ-linolenic acid both have anti-inflammatory effects and may be useful to help treat inflammatory diseases. The effects of these alone or combined were examined in patients with arthritis in a randomized controlled trial. Design Patients with rheumatoid arthritis or psoriatic arthritis were randomized into four groups in a double-blind, placebo-controlled parallel designed study. Patients received the respective capsules (1: 3.0 g n-3 LC-PUFA/d; 2: 3.2 g γ-linolenic acid/d; 3: 1.6 g n-3 LC-PUFA + 1.8 g γ-linolenic acid/d; 4: 3.0 g olive oil for a twelve week period. Clinical status was evaluated and blood samples were taken at the beginning and at the end of the period. Differences before and after intervention were tested with paired t-test or with Wilcoxon test for non-normal data distribution. Results 60 patients (54 rheumatoid arthritis, 6 psoriatic arthritis were randomised, 47 finished per protocol. In group 1, the ratio of arachidonic acid (AA/eicosapentaenoic acid (EPA decreased from 6.5 ± 3.7 to 2.7 ± 2.1 in plasma lipids and from 25.1 ± 10.1 to 7.2 ± 4.7 in erythrocyte membranes (p ≤ 0.001. There was no significant influence on AA/EPA ratio due to interventions in group 2-4. In group 2, the intake of γ-linolenic acid resulted in a strong rise of γ-linolenic acid and dihomo-γ-linolenic acid concentrations in plasma lipids, cholesteryl esters, and erythrocyte membranes. The combination of n-3 LC-PUFA and γ-linolenic acid (group 3 led to an increase of γ-linolenic acid and dihomo-γ-linolenic acid concentrations in plasma lipids, cholesteryl esters, and erythrocyte mem-branes. This increase was only half of that in group 2. Conclusions Incorporation of eicosanoid precursor FAs was influenced by an intake of n-3 LC-PUFA and γ-linolenic acid suggesting a possible benefit for therapy of chronic inflammatory diseases.

  10. Chronic blood pressure control.

    Brands, Michael W

    2012-10-01

    Chronic blood pressure is maintained within very narrow limits around an average value. However, the multitude of physiologic processes that participate in blood pressure control present a bewildering array of possibilities to explain how such tight control of arterial pressure is achieved. Guyton and Coleman and colleagues addressed this challenge by creating a mathematical model that integrated the short- and long-term control systems for overall regulation of the circulation. The hub is the renal-body fluid feedback control system, which links cardiac function and vascular resistance and capacitance with fluid volume homeostasis as the foundation for chronic blood pressure control. The cornerstone of that system is renal sodium excretory capability, which is defined by the direct effect of blood pressure on urinary sodium excretion, that is, "pressure natriuresis." Steady-state blood pressure is the pressure at which pressure natriuresis balances sodium intake over time; therefore, renal sodium excretory capability is the set point for chronic blood pressure. However, this often is misinterpreted as dismissing, or minimizing, the importance of nonrenal mechanisms in chronic blood pressure control. This article explains the renal basis for the blood pressure set point by focusing on the absolute dependence of our survival on the maintenance of sodium balance. Two principal threats to sodium balance are discussed: (1) a change in sodium intake or renal excretory capability and (2) a change in blood pressure. In both instances, circulatory homeostasis is maintained because the sodium balance blood pressure set point is reached.

    1989-03-01

    Three hundred and fifteen patients with anterior uveitis associated with juvenile chronic arthritis (JCA) were studied in order to identify the various risk factors for uveitis. Girls were more susceptible to uveitis than boys by a ratio of 3:1. In 94% of cases the uveitis was diagnosed after the development of arthritis. The risk of uveitis was small after seven or more years had elapsed from the onset of arthritis. Patients with pauciarticular onset JCA had the highest risk of uveitis and systemic onset patients the least risk. The presence of circulating antinuclear antibody was also an important marker for an increased risk of uveitis. A regimen for routine screening of patients is suggested.

    1992-05-01

    A case of Lyme arthritis with advanced degenerative changes localized to the midcarpal joint was treated with a limited wrist arthrodesis with relief of pain and improved function. Chronic Lyme arthritis occurs as the third stage of Lyme disease. Serologic testing and a history of a characteristic rash may be helpful in the diagnosis. Radiographic and histopathologic findings are nonspecific, with both degenerative and inflammatory characteristics. Intravenous antibiotics provide an effective treatment of chronic Lyme arthritis.

  16. Bite force and temporomandibular disorder in juvenile chronic arthritis.

    Science.gov (United States)

    Wenneberg, B; Kjellberg, H; Kiliaridis, S

    1995-08-01

    The aim of this study was to investigate the functional condition of the stomatognathic system in children suffering from juvenile chronic arthritis, with respect to bite force and temporomandibular disorder in relation to radiographic abnormalities of the mandibular condyle, occlusal factors and systemic disease parameters. Thirty-five children with juvenile chronic arthritis were compared to 89 healthy children with an Angle Class I occlusion and 62 children with an Angle Class II malocclusion. Subjective symptoms and clinical signs of temporomandibular disorder and radiographic mandibular condylar changes were more common in children with juvenile chronic arthritis than in the two comparison groups. Maximal molar and incisal bite forces and maximal molar bite force endurance times were also significantly reduced in children with juvenile chronic arthritis. It is concluded that the differences between the groups are caused mainly by the systemic inflammatory disease itself, but a functional influence of weakened masticatory muscles cannot be excluded.

    Over 90% of lead in blood is bound to the erythrocytes. This high affinity of lead for red cells may mean that chronic blood loss is a significant means for excretion of lead. This study sought correlations between blood lead levels and clinical conditions involving chronic blood loss. During May, June and July, 146 patients with normal hematocrits and red cell indices were identified from the hospital and clinic populations. For each patient, age, race, sex and medical history were noted, and a whole blood sample was analyzed by flameless atomic absorption spectrophotometry. Age-and race-matched pairs showed a significant correlation of chronic blood loss with lead levels. Patients with the longest history of blood loss (menstruating women) had the lowest level (mean 6.13 ..mu..g/dl, range 3.6-10.3 ..mu..g/dl). Post-menopausal women had levels (7.29 ..mu..g/dl, 1.2-14 ..mu..g/dl) comparable to men with peptic ulcer disease, or colon carcinoma (7.31 ..mu..g/dl, 5.3-8.6 ..mu..g/dl). The highest levels were among men who had no history of bleeding problems (12.39 ..mu..g/dl, 2.08-39.35 ..mu..g/dl). Chronic blood loss may be a major factor responsible for sexual differences in blood lead levels. Since tissue deposition of environmental pollutants is implicated in diseases, menstruation may represent a survival advantage for women.

  18. Pregnancy in Chronic Arthritis: Only a Matter of Planning

    Full Text Available Chronic arthritis often affects women of childbearing age. The old concept that having chronic arthritis constitutes a major obstacle to women when planning a pregnancy is now obsolete. Thanks to our current capacity to control the activity of rheumatoid arthritis and other chronic inflammatory conditions, and due to the availability of highly effective drugs such as tumour necrosis factor inhibitor agents and other biological agents, many women with these diseases are now able to consider the challenge of childbearing and raising children. Careful pre-conceptional evaluation and risk assessment constitutes the first step of proper care, which can be individualised according to the disease. More than ever, rheumatologists must know how to deal with this situation, and must be able to provide adequate counselling regarding the control of arthritis during conception and pregnancy.

There were 68 girls-84%, 13 boys-16%. We studied the clinical manifestations, the antinuclear antibodies (ANA using HEP-2 cells for the 33 pts with uveitis and 46 pts without uveitis, HLA status was determined for 36 pts. Results. 85,2% of the children had arthritis before uveitis. The mean age at onset of arthritis was 3,5 year (range: 1-10 yrs, the mean age at onset of uveitis was 6 year (range: 2-15 yrs. The mean interval between the onset of arthritis and uveitis was 3,02 years (range: 3,5 yrs before arthritis onset to 12,5 yrs after. In 68,1% pts the diagnosis of uveitis was made within 5 yrs after onset of arthritis. 93% of pts had mono-oligoarticular onset, but 50% had poliarticular course. 23,5% of pts had functional disability 3-4 classes. Ocular complications were developed in 53.1%: cataracts-38,3%, band keratopathy-11,1%, glaucoma-2,5%. 93,9% of 33 studied children with arthritis and uveitis were ANA positive, 9,1% were RF positive. 18,1 % had HLA-DR8 (p<0,001, 83,3% - HLA-A2 (p<0,00l, HLA-B27 - 30,6 % (p<0,00l. Conclusion. Clinical and laboratory data of our pts suggest that: lthe combination of arthritis and uveitis would be named JCA with uveitis; 2 according our opinion JCA with uveitis is separate nosological form among the juvenile arthritides.

    2011-04-01

    Full Text Available Childhood chronic arthritis of unknown etiology is known collectively as juvenile idiopathic arthritis (JIA and consists of heterogeneous subtypes with unique clinical patterns of disease. JIA is the commonest rheumatic disease in children and may still result in significant disability, with joint deformity, growth impairment, and persistence of active arthritis into adulthood. Basic research is rather focused on rheumatoid arthritis, and this lead to small number of publications considering JIA. In this study we examine, by flow cytometry, the expression of dendritic cells (DCs in the peripheral blood and synovial fluid of children with active JIA in a group of 220 patients. We reveal a significant decrease in the percentage of immature DCs in the blood of patients compared to control children. Surprisingly, we found higher percentages of mature circulating dendritic cells. Both populations of DCs, immature and mature, were accumulated in patients’ synovial fluid. We also confirmed the presence of CD206+/CD209+ in JIA samples, which can represent a population of macrophages with dendritic cells morphology. Our results support the thesis that dendritic cells are crucial in the induction and maintenance of autoimmune response and local inflammation during juvenile idiopathic arthritis.

    2014-01-01

    Chronic kidney disease (CKD) is a comorbid condition that affects, based on recent estimates, between 47% and 54% of patients with gouty arthritis. However, data from randomized controlled trials in patients with gouty arthritis and CKD are limited, and current gouty arthritis treatment guidelines do not address the challenges associated with managing this patient population. Nonsteroidal anti-inflammatory drugs and colchicine are recommended first-line treatments for acute gouty arthritis attacks. However, in patients with CKD, nonsteroidal anti-inflammatory drugs are not recommended because their use can exacerbate or cause acute kidney injury. Also, colchicine toxicity is increased in patients with CKD, and dosage reduction is required based on level of kidney function. Allopurinol, febuxostat, and pegloticase are all effective treatments for controlling elevated uric acid levels after the treatment of an acute attack. However, in patients with CKD, required allopurinol dosage reductions may limit efficacy; pegloticase requires further investigation in this population, and febuxostat has not been studied in patients with creatinine clearancegouty arthritis including urate-lowering therapy in patients with CKD. Challenges specific to primary care providers are addressed, including guidance to help them decide when to collaborate with, or refer patients to, rheumatology and nephrology specialists based on the severity of gout and CKD.

    The chronic chikungunya arthritis symptoms closely mimic the rheumatoid arthritis (RA) symptoms, thus making it difficult to distinguish between these two clinical entities. The current comparative study characterizes NK (CD3(-)CD56(+)) and NK-like T (CD3(+)CD56(+)) cell responses in patients with chronic chikungunya arthritis and RA. Phenotype and functions of NK and NK-like T cells repertoire were assessed in 56 chronic chikungunya arthritis, 26 RA patients and 82 controls using flow cytometry. TNF-α and IFN-γ-secreting NK-like T cells were high in both chronic arthritis patients than in controls. Percentage of TNF-α(+) NK cells was higher in RA patients than in controls. Percentage of perforin(+) NK cells was low in both chronic arthritis patient groups. Among the patient groups, expressions of perforin(+) and IFN-γ(+) NK-like T cells were higher in RA. Overall, our data show reduced frequency of NK-like T cells, lower expression of perforin(+) NK, higher expression of TNF-α(+) NK-like T and IFN-γ(+) NK-like T cells as the markers of chronic arthritic diseases. In the absence of any specific treatment for chronic chikungunya induced arthritis and promising results of anti-TNF-α therapy against RA, current data may form the basis for future in vivo studies and has scope as possible therapeutics against chikungunya.

  7. Chronic gonococcal arthritis with C5 deficiency presenting with brief flare-ups: case study and literature review.

    Gonococcal arthritis is typically acute and appears within 3 weeks after initial infection. Chronic gonococcal arthritis is now exceptionally rare, since the advent of the antibiotic era. Numerous host factors are involved in gonococcal dissemination, such as complement deficiency, HIV and gonococcus strain characteristics. Gonococcal arthritis shares the same risk factors. In this instance, our patient was a 16-year-old girl suffering from persistent polyarthralgia with joint swelling presenting with brief flare-ups for a period of 1 year. She disclosed a single episode of unprotected sexual intercourse 1 year ago, i.e. just before developing her first rheumatological symptoms. Therefore, we performed a joint aspiration (arthrocentesis), and synovial fluid was inoculated directly into aerobic and anaerobic blood culture bottles, which tested positive for Neisseria gonorrhoeae within 24 h. Clinical presentation was consistent with previous reports of chronic gonococcal arthritis. Further investigation revealed a C5 complement deficiency, which might explain the chronic Neisseria process. A favourable outcome was reached after a ten-day course of IV ceftriaxone, with no apparent sequelae found during follow-up 6 weeks later. This case demonstrates an unusual gonococcal arthritis with brief flare-ups for the course of a year, followed by a subacute form. N. meningitidis infections, similar to N. gonorrhoeae, are typically acute and may sometimes be involved in chronic processes. However, this characteristic appears to be rare in the case of N. gonorrhoeae. Risk factors for this chronic process will be discussed with a review of the literature.

    1988-01-01

    Three hundred and fifteen patients with anterior uveitis and juvenile chronic arthritis were reviewed in order to determine the incidence, visual prognosis, and the clinical characteristics of the intraocular inflammation. The overall incidence of uveitis was 20%. Approximately 25% of patients had relatively mild and/or transient involvement and an excellent visual prognosis. In 50% the uveitis was more severe but could be controlled with topical medication. In the remaining 25% the visual prognosis was poor due to the intractable nature of the uveitis and the subsequent development of vision-threatening complications. The majority of patients (74%) were under the age of 8 years when the uveitis was first diagnosed. Clinically, the intraocular inflammation was most frequently an asymptomatic, chronic, non-granulomatous, iridocyclitis which was bilateral in 71% of cases. Other ocular lesions, which were rare, included keratoconjunctivitis sicca and corneal melting.

    Full Text Available Objective: to estimate a need for conservative rehabilitation treatment in patients with juvenile chronic arthritis (JCA.Material and methods. Data on the principles and procedures of rehabilitation treatment were analyzed in patients with JCA on the basis of 25- year experience. The need for these packages of measures in 1999, 2008, and 2014 was compared. Standard procedures for joints at different sites were described. According to the degree of joint functions, there were rehabilitation treatment packages: corrective, mobilization, and general health-improving.Results and discussion. All patients with juvenile arthritis need rehabilitation (physical, psychological, and social. Comparison of the total number of patients who had received rehabilitation treatment in 1999, 2008, and 2014 showed a small trend towards its reduction. This is due to the smaller number of patients with dysfunctions and to the larger number of those without movement disorders who had received adequate treatment in early periods of the disease. The high percentage of patients having limited joint functions needs a mobilization package. Analysis of the data available in the literature and the authors' experience may lead to the conclusion that all patients with JCA need exercise therapy. The latter is a major procedure for physical rehabilitation and should be included in the standards for adjuvant treatment during basic medical therapy. Emphasis is laid on the importance of the early initiation of treatment to prevent incapacitating deformity at early stages of the disease.

    Objective To study the clinical and biochemical effects of a low starting dose for gold therapy in rheumatoid arthritis patients with a contact allergy to gold. Methods Serum cytokines were assayed before and 24 h after the first injection of gold sodium thiomalate (GSTM). Results Contact allergy to gold was found in 4 of 19 patients. Compared to gold-negative patients (starting dose: 10 mg GSTM), there was a larger increase in serum TNFalpha (p < 0.05), sTNF-R1 (NS), and IL-1 ra (p < 0.05) in gold-allergic patients. Conclusions Cytokines are released in blood by GSTM in RA patients with gold allergy. To minimize the risk of acute adverse reactions the starting dose of GSTM should be lowered to 5 mg. Alternatively, patients should be patch-tested before gold therapy; in test-positive cases, 5 mg is recommended as the first dose. PMID:11860615

    OBJECTIVE: To assess blood vessel stability in inflammatory synovial tissue (ST) and to examine neural cell adhesion molecule (NCAM), oxidative DNA damage, and hypoxia in vivo. METHODS: Macroscopic vascularity and ST oxygen levels were determined in vivo in patients with inflammatory arthritis who were undergoing arthroscopy. Vessel maturity\\/stability was quantified in matched ST samples by dual immunofluorescence staining for factor VIII (FVIII)\\/alpha-smooth muscle actin (alpha-SMA). NCAM and 8-oxo-7,8-dihydro-2\\'-deoxyguanosine (8-oxodG) were examined by immunohistochemistry. Angiogenesis was assessed in vitro, using human dermal endothelial cells (HDECs) in a Matrigel tube formation assay. RESULTS: A significant number of immature vessels (showing no pericyte recruitment) was observed in tissue from patients with inflammatory arthritis (P < 0.001), in contrast to osteoarthritic and normal tissue, which showed complete recruitment of pericytes. Low in vivo PO(2) levels in the inflamed joint (median [range] 22.8 [3.2-54.1] mm Hg) were inversely related to increased macroscopic vascularity (P < 0.04) and increased microscopic expression of FVIII and alpha-SMA (P < 0.04 and P < 0.03, respectively). A significant proportion of vessels showed focal expression of NCAM and strong nuclear 8-oxodG expression, implicating a loss of EC-pericyte contact and increased DNA damage, levels of which were inversely associated with low in vivo PO(2) (P = 0.04 for each comparison). Circulating cells were completely negative for 8-oxodG. Exposure of HDEC to 3% O(2) (reflecting mean ST in vivo measurements) significantly increased EC tube formation (P < 0.05). CONCLUSION: Our findings indicate the presence of unstable vessels in inflamed joints associated with hypoxia, incomplete EC-pericyte interactions, and increased DNA damage. These changes may further contribute to persistent hypoxia in the inflamed joint to further drive this unstable microenvironment.

  1. MRI and ultrasound in children with juvenile chronic arthritis

    Energy Technology Data Exchange (ETDEWEB)

    Lamer, S.; Sebag, G.H

    2000-02-01

    In this era of advancing imaging technology, a knowledge of the relative values of available imaging techniques is necessary to optimize the management of children with juvenile chronic arthritis (JCA). After clinical examination, plain films remain the initial investigation. The need for radiation protection must be a priority in children with JCA. Conventional radiographs allow grouping of the various arthritides (on the base of the distribution and pattern of joint space changes) and staging of disease progression. Ultrasound (US) is very sensitive in the detection of joint effusions, especially in the hip, and guides fluid aspiration. US and Doppler can be used for the evaluation of synovial hypertrophy and activity. Arthrography and to a certain extent nuclear studies have been replaced by magnetic resonance imaging (MRI). MRI can demonstrate articular cartilage, joint effusion, synovial hypertrophy, cortical and medullary bone, cartilage and bone perfusion, and fibrocartilaginous structures (menisci and ligaments). Contrast enhanced MRI is the most sensitive modality to determine whether an arthritic condition is present. However, it does not assist in establishing a specific diagnosis. MRI determines accurately the activity and the extent of the disease and is particularly useful in the early detection of articular damage. Finally, MRI is of major importance in the evaluation of response to local therapy (especially steroids) and the detection of complications.

    The objectives of this study are to assess the frequency of chronic arthritis and compare the clinical and laboratory features in a large population of childhood-onset systemic lupus erythematosus (cSLE) and adult-onset (aSLE) patients. This historical study evaluated 336 cSLE and 1830 aSLE patients. Chronic arthritis was defined as synovitis of at least 6 weeks of duration. Rhupus was characterised as the association of SLE and chronic inflammatory arthritis with erosion and positive rheumatoid factor. Jaccoud's arthropathy is a non-erosive subluxation leading to severe deformity of the hands and feet. Data were compared using Student's t test or the Mann-Whitney test for continuous variables. For categorical variables, differences were assessed by Fisher's exact test and Pearson chi-square. Frequencies of chronic arthritis were similar in cSLE and aSLE (2.4 vs. 3.8%, p = 0.261). The median time from disease onset to appearance of chronic arthritis was shorter in cSLE (0 vs. 10 years, p lupus anticoagulant (40 vs. 1.6%, p = 0.012), anticardiolipin IgM (40 vs. 1.5%, p = 0.012) and median Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) [10.5(1-20) vs. 6(4-16), p = 0.029] were higher in cSLE. Frequency of rhupus, (12 vs. 17%, p = 1.0), Jaccoud's arthropathy (0 vs. 17%, p = 0.343) and treatments were similar in cSLE and aSLE. We determined that chronic arthritis in SLE has distinct features in children, with very early onset, polyarticular involvement and association with active disease. We further demonstrated in this series that a proportion of chronic arthritis involvement in SLE is manifested as rhupus and Jaccoud's arthropathy.

    Full Text Available Joint syndrome evolution was prospectively followed up in a 49-year-old woman who had serum hepatitis in 1990. When she came to a rheumatologist for the first time in 1999 she complained of occasional joint pain. She did not have joint inflammatory changes at that time but chronic hepatitis С was revealed at the examination. Hepatitis С diagnosis was confirmed by morphological and repeated virological evaluations. During antiviral treatment the pt developed symmetrical polyarthritis involving hand joints. Elevation of cryoglobuline, rheumatoid factor and antinuclear antibodies level was revealed. During the next year polyarthritis recurred and later acquired undulatory course with periods of exacerbation and stabilization. Attempts of treatment with sulfasalazine failed due to transaminase elevation. In 2006 ulnar deviation appeared and rheumatoid factor level remained elevated. MRI showed multiple erosions of carpal bones. Considering features of joint syndrome development joint damage in this pt was regarded as arthritis associated with chronic hepatitis C.

    2007-06-01

    Though patients with chronic fatigue syndrome (CFS) have lots of complaints, abnormal findings cannot be detected by biochemical screening tests. However, some specialized blood tests have revealed neuroendocrine immune axis abnormalities, which is closely associated with each other. Recent studies indicate that CFS can be understood as a special condition based on abnormality of the psycho-neuro-endocrino-immunological system, with the distinguishing feature of CFS seeming to be the secondary brain dysfunction caused by several cytokines and/or autoantibodies. In this paper, we summarize these abnormalities found in CFS and show the neuro-molecular mechanism leading to chronic fatigue.

    1987-10-01

    Abnormalities on computed tomography (CT) are described in 12 adults in whom septic arthritis of the hip was diagnosed. Presenting symptoms varied, as did CT findings. Soft tissue abnormalities ranged from intra-articular effusion to large abscess formation, and bone changes ranged from minimal erosion of articular surfaces to gross destruction of the proximal femur and acetabulum. CT can be helpful in the evaluation of septic arthritis of the hip because of its superior demonstration of soft tissue detail. An accurate diagnosis can be established in unsuspected cases and can be confirmed when clinical indicators are vague.

In recent years, a great number of studies have investigated the possible role of reactive oxygen species in the etiology and pathogenesis of Rheumatoid Arthritis. The aim of this study was to analyze the level of activities of catalase, glutathione peroxidas (GSH-Px, Super oxide dismotase (SOD in patients with RA compared with the healthy subjects. Methods: In a case-control study sixty rheumatoid arthritis patients 18-75 years old and 60 healthy sex and age-matched controls were selected, Catalase activity was measured by determining the constant rate (k of hydrogen peroxide decomposition. GSH-Px activity of plasma was measured with spectrophotometer by Glutathione oxide generation due to GSH-Px. SOD activity is measured by degree of inhibition effect of SOD in generating super oxide radicals by xanthine and xanthine oxidase. C-reactive protein and rheumatoid factor values were determined by agglutination and latex tests. Results: The plasma activity of catalase (p0.05. There was a negative significant relation between C reactive protein and Rheumatoid factor values with the erythrocyte activity of catalase and GSH-Px (p<0.01. Conclusion: These results suggested that oxidative stress plays a very important role in the inflammation and pathogenesis of RA.

    2006-11-01

    We present a 40-year-old woman complaining of worsening chest pain. She was previously treated with a prolonged course of antibiotics for suspected sternal osteomyelitis. Radiological investigations were suggestive of ongoing inflammation within the manubriosternal joint. Formal surgical debridement yielded evidence corroborating the diagnosis although microbiological samples were negative. Prolonged empirical treatment with intravenous antibiotics leads to a complete resolution of symptoms. Primary culture-negative manubriosternal septic arthritis is rare, and suboptimal treatment, particularly if confused with other conditions such as synovitis, acne, pustulosis, hyperostosis and osteitis (SAPHO) syndrome, compounds its considerable morbidity.

Results. Dyslipidemia (DLP frequency analysis showed differences only for LP(a. Increase of LP(a and TG concentrations in RA was more frequent than in control. CL and HDLC levels did not differ. Intima-media complex (IMC thickness in RA and control was the same. Atherosclerotic plaques (AP in RA were more frequent. RA pts showed negative correlation between IMC thickness and HDLC, as well as between HDLC values, apoAl and CRP. LP(a level correlated with DAS4. There was no association between concentrations of CL, TG, HDLC, low-density lipoprotein cholesterol (LDLC, apo В and Al, LP(a and extra-articular RA features and glucocorticoid administration. In pts with high LP(a level AP were more frequent, activity of RA, apo B, LDLC levels were higher than in pts with normal level of this LP. LP(a values in pts with AP were higher than in pts without AP (p<0,05. Conclusion. Chronic inflammation in RA plays an important role in disturbances in blood cholesterol transport system. LP(a level increase is a risk factor of atherosclerotic vascular damage.

    Full Text Available Abstract Background High prevalence rates for rheumatoid arthritis, spondyloarthopathies, and systemic lupus erythematosus have been described in American Indian and Alaskan Native adults. The impact of these diseases on American Indian children has not been investigated. Methods We used International Classification of Diseases-9 (ICD-9 codes to search two Indian Health Service (IHS patient registration databases over the years 1998–2000, searching for individuals 19 years of age or younger with specific ICD-9-specified diagnoses. Crude estimates for disease prevalence were made based on the number of individuals identified with these diagnoses within the database. Results Rheumatoid arthritis (RA / juvenile rheumatoid arthritis (JRA was the most frequent diagnosis given. The prevalence rate for JRA in the Oklahoma City Area was estimated as 53 per 100,000 individuals at risk, while in the Billings Area, the estimated prevalence was nearly twice that, at 115 per 100,000. These rates are considerably higher than those reported in the most recent European studies. Conclusion Chronic arthritis in childhood represents an important, though unrecognized, chronic health challenge within the American Indian population living in the United States.

    A combination of surgical and medical treatment is normally required for patients with septic arthritis. Antibiotics selected for use on these patients are normally based on tissue culture results. However, in sub-acute and chronic septic arthritis cases, the results of the culture are usually negative as a result of prior treatment. The present study will investigate the incidence of culture-negative septic arthritis and the outcomes based on the use of first-line drug antibiotics for the treatment of sub-acute and chronic septic arthritis. For the present study, the authors retrospectively reviewed medical records of surgically treated septic arthritis cases over the past 10 years at Siriraj Hospital. The patient culture results, the antibiotics used, and the results of treatment were all recorded and analyzed. One hundredfifty-three septic arthritis patients were reviewed. Sixty-two patients were classified as having been diagnosed with either sub-acute or chronic septic arthritis. Thirty-six of 62 patients (58.1%) had a negative culture result. In the culture-positive patients, 42.3% had Streptococcus, 26.9% had Staphylococcus aureus, 11.5% had other gram positive bacteria, 15.4% had gram-negative bacteria, and 3.8% had tuberculus infection. In the culture-negative sub-acute and chronic group (36 of 62), 23 patients received Cefazolin, nine patients received Cloxacillin, and four patients received Clindamycin. Successful results were 69.9%, 66.7% and 75%, respectively. The present study reflects that the incidence ofculture-negative, sub-acute and chronic septic arthritis is approximately 58.1%. The first-line class of antibiotics remains the appropriate antibiotic choice for these patients because they are still effective for treatment of septic arthritis in up to 70% of all cases.

Materials and methods. 101 patients at the age of 60.6 ± 11.8 years, 92 % of women, with reliable rheumatoid arthritis (American College of Rheumatology – ACR, 1987, were examined. The visual analog scale was used for an assessment of pain strength at the moment; the Van Korff’s questionnaire – for determination of pain strength at the moment and retrospectively for the last half a year with an assessment of disadaptation level and disability, ranging of a chronic pain syndrome on classes; the McGill Pain Questionnaire – for the characteristic of touchsensitive and emotional components of pain. Neuropathic pain was revealed by DN4 questionnaire. Anxiety and depression were determined by the Hospital Anxiety and Depression Scale (HADS. Fibromyalgia diagnosed by criteria of ACR, (1990. Results. Pain estimated by various scales and questionnaires varied from moderated to intensive. According to Van Korff’s questionnaire it was characterized by average level of disadaptation and easy disability that corresponded to the second class of chronic pain. The Rank pain index of the McGill Pain Questionnaire touch scale testified that pain was described by a smaller number of definitions on a touch scale than on emotional. This indicates a moderate impact of pain syndrome on a state of mind. Neuropathic pain is diagnosed for 37.3 % of patients with tunnel syndrome, mononeuritis and touch polyneuropathy. The secondary fibromyalgia is revealed for 2 % of patients with early rheumatoid arthritis of high activity. According to HADS anxiety and depression was revealed for 58 and 59 % of patients correspondingly. This demanded psychotherapeutic consultation and additional correction.

    Rheumatoid arthritis (RA) and chronic periodontitis are the most common chronic inflammatory diseases with remarkable pathological and clinical similarities. A lot of similarities exist between RA and periodontitis at cellular and molecular levels. The relationship between these two chronic inflammatory diseases is still unclear. This case-control study was undertaken to determine the possible association between chronic inflammatory diseases like RA and periodontitis. The case group consisted of 100 patients attending the Rheumatology clinic who have rheumatoid arthritis (RA group). Age- and gender-matched 112 patients without RA attending the Outpatient wing of Department of General Medicine formed the control group (NRA group). The number of missing teeth, gingival index (GI), oral hygiene index-simplified (OHI-S), probing pocket depth (PPD) and clinical attachment levels (CAL) were evaluated in both the groups. Rheumatoid disease activity was assessed by DAS-28 score system. Systemic markers of inflammation like erythrocytic sedimentation rate (ESR) and serum levels of C-reactive protein (CRP) were assessed. There was a statistically significant difference in GI, OHI-S, PPD, CAL, ESR and CRP levels between cases (RA group) and controls (NRA group) (P < 0.05). Among subjects with RA, there was no association between the rheumatoid disease activity and the severity of periodontal disease. The occurrence and severity of periodontitis was found to be higher in RA subjects as compared to subjects without RA, suggesting a positive relation between these two chronic inflammatory diseases.

    Full Text Available Introduction. Knee flexion contractures are common after-effects of juvenile arthritis. Treatment is usually conservative and may include physical therapy and kinesitherapy. Surgical treatment, particularly of the soft parts, indicated for contractures resistant to conservative treatment, helps to correct the deformity, maintain movements, and relieves pain. Intensive postoperative physiotherapy is of special importance. Case report. A 23-year-old female patient with chronic juvenile arthritis since the age of one was admitted for treatment of flexion con­tractures in both knees, muscle hypotrophy, loss of strength and gait disability. The patient underwent arthroscopic synovectomy. The operation was first performed on the right and after 3 mouths on the left knee. The pre operative range of motion in the rigth knee was 30°-70° and in the left 40°-80°. The patient underwent intensive physical therapy to reduce postoperative swelling of knees and firstly passive and then active kinesitherapy. Nine months after the first surgery and six months after the second, the range of motion in the right knee was 0°-100° and in the left 0°-105°. The strength of tested muscles was increased and gait was improved. Conclusion. Management and rehabilitation of patients with chronic juvenile arthritis include maintenance or improvement in position and function of joints that is achieved with synovectomy. The results depend on combined interdisciplinary rehabilitation, well-experienced staff, and pre- and post-operative physiotherapy as well as kinesitherapy. Arthroscopic synovectomy has many advantages and we believe that it was a better solution than open capsulosynovectomy in this patient with chronic juvenile arthritis of the knee. .

    Full Text Available Objectives: Muscle blood flow in the forearm of patients with rheuma-toid arthritis and healthy volunteers following treatment with temperature increasingarm baths, mudpacks and short- or decimeter-wave diathermy was studied in thisinvestigation. The aim of the study was to find out the difference of reactive hyperemia between the different temperature methods as well as the influence on theconsensual reaction. Subjects: Eighty patients with rheumatoid arthritis, stage 3 according toSteinbrocker, as well as 80 healthy human subjects had been assigned numerically in the four therapy- and controlgroups. Patients with diseases influencing the peripheral blood flow were excluded. Design: Blood flow was measured by venous occlusion plethysmography in both forearms with the subjects lyingsupine. The application of the local heat therapies had been excluded on the left forearm. The forearm blood flow wasmonitored before heat therapy, directly after as well as in two further 10 minutes intervals. An analysis of variancewas used to determine the influence on blood flow of the response to the heat therapies in patients with rheumatoidarthritis and healthy subjects.Results: Under homogeneous starting conditions and a statistically uniformed high blood flow in rest the reactive values of blood flow on the left-hand side of application and the right consensual side showed high significant differencesbetween all methods of therapy. Differences between the patients and the healthy subjects only showed tendencies withpartially lower reactions, concerning the patients with rheumatoid arthritis. All methods of heat therapy caused a statistically provable consensual reaction that turned out smaller after diathermic methods. Here the post therapeuticreaction of the blood flow on the side of application was also lower or rather shorter. Conclusion: Greater differences of the blood flow in rest between the patients with rheumatoid arthritis and healthysubjects

    Full Text Available Abstract. Characteristics of myeloid and plasmacytoid dendritic cells from peripheral blood were studied in healthy donors and patients with rheumatoid arthritis (RA. We evaluated relative amounts of dendritic cell by their subtypes, degree of their maturity, and ability to respond to the maturation factors (toll-like receptor 4, 7 and 8 agonists. The results of in vitro experiments have shown that the patients with rheumatoid arthritis exhibited a significant reduction in numbers of plasmacytoid dendritic cells from peripheral blood. A sufficient decrease in CD83, CD80 expression on dendritic cell subtypes in RA patients was significantly less, than in healthy donors. In patients with RA, a significant increase in the number of CCR7-expressing plasmacytoid dendritic cells was shown in peripheral blood. In stimulated cultures, maturation of dendritic cells expressing maturation markers (CD83, CD80, CCR7 proved to be increased up to normal values. It should be noted that the counts of plasmacytoid dendritic cells in peripheral blood of RA patients expressing CCR7 was significantly higher than among healthy donors. Meanwhile, expression of CD83 and CD80 increased tovalues of healthy donors.Hence, we have found a significant reduction in relative counts of blood-derived myeloid and plasmacytoid dendritic cells expressing markers of mature dendritic cells (CD83, CD80 in patients with rheumatoid arthritis. Upon stimulated in vitro maturation, the counts of myeloid and plasmacytoid dendritic cells expressing CD83 and CD80 increased to the values corresponding to those of control group. RA patients showed significantly higher numbers of plasmacytoid dendritic cells expressing CCR7. This could indicate some changes in functional activity of dendritic cells in peripheral blood of patients with RA.

    Full Text Available Abstract Background Recent studies have demonstrated a role for spinal p38 MAP kinase (MAPK in the development of chronic inflammation and peripheral arthritis and a role for GABA in the inhibition of p38 MAPK mediated effects. Integrating these data suggests that GABA may play a role in downregulating mechanisms that lead to the production of proinflammatory agents such as interleukin-1, interleukin-6, and matrix metalloproteinase 3 – agents implicated in the pathogenesis of rheumatoid arthritis (RA. Genetic studies have also associated RA with members of the p38 MAPK pathway. Hypothesis We propose a hypothesis for an inefficient GABA signaling system that results in unchecked proinflammatory cytokine production via the p38 MAPK pathway. This model also supports the need for increasing research in the integration of immunology and neuroscience.

    ABSTRACT: INTRODUCTION: Cartilage oligomeric matrix protein (COMP) is a homopentameric protein in cartilage. The development of arthritis, like collagen-induced arthritis (CIA), involves cartilage as a target tissue. We have investigated the development of CIA in COMP-deficient mice. METHODS: COMP......-deficient mice in the 129/Sv background were backcrossed for 10 generations against B10.Q mice, which are susceptible to chronic CIA. COMP-deficient and wild-type mice were tested for onset, incidence, and severity of arthritis in both the collagen and collagen antibody-induced arthritis models. Serum anti......-collagen II and anti-COMP antibodies as well as serum COMP levels in arthritic and wild-type mice were measured by enzyme-linked immunosorbent assay. RESULTS: COMP-deficient mice showed a significant early onset and increase in the severity of CIA in the chronic phase, whereas collagen II-antibody titers were...

    Human leukocyte antigen-antigen D related (HLA-DR) molecules are highly expressed in synovial tissue (ST), the target of the immune response in chronic inflammatory forms of arthritis. Here, we used LC-MS/MS to identify HLA-DR-presented self-peptides in cells taken directly from clinical samples: ST, synovial fluid mononuclear cells (SFMC), or peripheral blood mononuclear cells (PBMC) from five patients with rheumatoid arthritis (RA) and eight with Lyme arthritis (LA). We identified 1593 non-redundant HLA-DR-presented peptides, derived from 870 source proteins. A total of 67% of the peptides identified in SFMC and 55% of those found in PBMC were found in ST, but analysis of SFMC/PBMC also revealed new antigen-presented peptides. Peptides were synthesized and examined for reactivity with the patients' PBMC. To date, three autoantigens in RA and four novel autoantigens in LA, presented in ST and/or PBMC, were shown to be targets of T- and B-cell responses in these diseases; ongoing analyses may add to this list. Thus, immunoprecipitation and LC-MS/MS can now identify hundreds of HLA-DR-presented self-peptides from individual patients' tissues or fluids with mixed cell populations. Importantly, identification of HLA-DR-presented peptides from SFMC or PBMC allows testing of more patients, including those early in the disease. Direct analysis of clinical samples facilitates identification of novel immunogenic T-cell epitopes.

    A soluble form of CD21 (sCD21) and CD23 (sCD23) is released from the surface of human white blood cells upon shedding of the extracellular domain. sCD21 circulates in a complex with cleavage fragments of C3 and sCD23, which were previously identified as ligands of membrane and soluble CD21. sCD21 seems to be a marker of chronic inflammatory disease. To assess the sCD21 and sCD23 status in patients with subsets of juvenile arthritis (JA), we determined plasma levels sCD21 and sCD23. Plasma sCD21 levels were significantly decreased in all JA subtypes (O-JA P < 0.0068; P- and S-JA P < 0.0001) compared to healthy controls. Plasma sCD23 levels were significantly decreased in P-JA and S-JA (both P < 0.0001), but not in O-JA (P < 0.3843) in comparison with healthy controls, and data statistically analyzed. Our results suggest that pathological mechanisms relevant to autoimmune disorders interfere with the regulation of both CD21 and CD23 shedding.

    During an uncontrolled, open-labelled, open-ended clinical trial of auranofin in children with juvenile rheumatoid arthritis (JRA) we obtained serial blood samples for the purpose of assessing gold content. Our objectives were (1) to observe the pattern of blood gold concentrations over a period of time in children undergoing long-term oral gold therapy, and (2) to observe the effect of changing dosage levels on blood gold concentrations. The initial dosage of auranofin was 0.1 mg/kg/day with allowable increases to 0.2 mg/kg/day. A concurrent nonsteroidal anti-inflammatory drug was allowed. Twenty-one patients were enrolled in the study, and we obtained 2 or more serial samples on 13 of the children. At a constant dosage of 0.1 mg/kg/day, steady state blood gold concentrations were attained in 11 to 13 weeks of therapy and, in the absence of a dosage change, remained remarkably constant through extended periods. The blood gold concentration was related to total daily dosage rather than to the cumulative amount of gold received. Increasing or decreasing the dose resulted in a direct effect on concentration. The clinical value of blood gold levels resulting from auranofin therapy in JRA will have to be established through double-blind controlled trials.

  7. Blood Dendritic Cells: Canary in the Coal Mine to Predict Chronic Inflammatory Disease?

    2014-01-01

    Full Text Available The majority of risk factors for chronic inflammatory diseases are unknown. This makes personalized medicine for assessment, prognosis, and choice of therapy very difficult. It is becoming increasingly clear, however, that low-grade subclinical infections may be an underlying cause of many chronic inflammatory diseases and thus may contribute to secondary outcomes (e.g. cancer. Many diseases are now categorized as inflammatory-mediated diseases that stem from a dysregulation in host immunity. There is a growing need to study the links between low-grade infections, the immune responses they elicit, and how this impacts overall health. One such link explored in detail here is the extreme sensitivity of myeloid dendritic cells (mDC in peripheral blood to chronic low-grade infections and the role that these mDCs play in arbitrating the resulting immune responses. We find that emerging evidence supports a role for pathogen-induced mDCs in chronic inflammation leading to increased risk of secondary clinical disease. The mDCs that are elevated in the blood as a result of low-grade bacteremia often do not trigger a productive immune response, but can disseminate the pathogen throughout the host. This aberrant trafficking of mDCs can accelerate systemic inflammatory disease progression. Conversely, restoration of DC homeostasis may aid in pathogen elimination and minimize dissemination. Thus it would seem prudent when assessing chronic inflammatory disease risk to consider blood mDC numbers, and the microbial content (microbiome and activation state of these mDCs. These may provide important clues (the canary in the coal mine of high inflammatory disease risk. This will facilitate development of novel immunotherapies to eliminate such smoldering infections in atherosclerosis, cancer, rheumatoid arthritis, and pre-eclampsia.

Following induction of arthritis, the treatment group received intra-articular BoNT/B. Arthritic control groups were treated with intra-articular normal saline or sham injections. Pain behavior testing was performed prior to arthritis, after induction of arthritis, and following treatments. Pain behavior measures included analysis of gait impairment (spontaneous pain behavior and joint tenderness evaluation (evoked pain response. Strength was measured as ability to grasp and cling.Results: Visual gait analysis showed significant impairment of gait in arthritic mice that improved 43% after intra-articular BoNT/B, demonstrating a substantial articular analgesic effect. Joint tenderness, measured with evoked pain response scores, increased with arthritis induction and decreased 49.5% after intra-articular BoNT/B treatment. No improvement in visual gait scores or decrease in evoked pain response scores were found in the control groups receiving intra-articular normal saline or sham injections. Intra-articular BoNT/B was safe, and no systemic effects or limb weakness was noted.Conclusions: This study is the first report of intra-articular BoNT/B for analgesia in a murine model of arthritis pain. The results of this study validate prior work using intra-articular neurotoxins in murine models. Our findings show chronic degenerative arthritis

  12. The Mechanisms Underlying Chronic Inflammation in Rheumatoid Arthritis from the Perspective of the Epigenetic Landscape

    2016-01-01

    Full Text Available Rheumatoid arthritis (RA is a chronic inflammatory autoimmune disease that is characterized by synovial hyperplasia and progressive joint destruction. The activation of RA synovial fibroblasts (SFs, also called fibroblast-like synoviocytes (FLS, contributes significantly to perpetuation of the disease. Genetic and environmental factors have been reported to be involved in the etiology of RA but are insufficient to explain it. In recent years, accumulating results have shown the potential role of epigenetic mechanisms, including histone modifications, DNA methylation, and microRNAs, in the development of RA. Epigenetic mechanisms regulate chromatin state and gene transcription without any change in DNA sequence, resulting in the alteration of phenotypes in several cell types, especially RASFs. Epigenetic changes possibly provide RASFs with an activated phenotype. In this paper, we review the roles of epigenetic mechanisms relevant for the progression of RA.

    The authors examined the role of ultrasound (US) in diagnosis and management of heel pain in chronic inflammatory arthritis. Nineteen patients underwent US examination. Eight patients (2 with previously unsuccessful nonguided injections), had 11 US-guided corticosteroid injections for treatment of retrocalcaneal bursitis (n = 6), plantar fasciitis (n = 3), and posterior tibial tenosynovitis (n = 2). US-demonstrated Achilles tendon rupture (n = 2), Achilles tendinitis (n = 8), posterior tibial tenosynovitis (n = 6), peroneus longus tenosynovitis (n = 2), retrocalcaneal bursitis (n = 13), and plantar fasciitis (n = 4). Loss of smooth bone contour (n = 13) correlated with bone erosions on plain radiographs in all but one case. Ten of 11 guided injections resulted in full resolution of heel pain. The diverse causes of heel pain are highlighted, and the ability of US to provide information with management implications is confirmed. US-guided corticosteroid injection is beneficial, especially after failure of nonguided injection.

    A high performance liquid chromatography (HPLC) method has been developed for measuring salicylic acid in the plasma and saliva of children with juvenile chronic arthritis (JCA). Samples were extracted with diethyl ether and, after drying, redissolved in methanol to be chromatographed. Quantitation of salicylic acid was performed by reverse phase HPLC on a spherisorb ODS-2 column, using methanol: water: acetic acid as mobile phase. Phenolic was monitored by absorbance at 237 nm. Linearity between the amount of mass injected and the response in the detector was determined. This method was applied to compare concentrations of salivary and plasma salicylic acid. The method also permitted the quantitation of salivary salicylate as a non-invasive, indirect method for monitoring the concentration of plasma salicylate in patients with JCA.

    Full Text Available Abstract Background Short bowel syndrome (SBS may induce a plethora of clinical symptoms ranging from underweight to nutrient-, vitamin- and electrolyte deficiencies. The objective of this case report is to illustrate how demanding the management of a 60 year old patient with SBS and recurrent joint attacks was for different medical disciplines. Case presentation The patient with SBS presented with a body mass index of 16.5 kg/m2 after partial jejunoileal resection of the small intestine with a six year long history of recurrent pain attacks in multiple peripheral joints, chronic diarrhoea and food intolerances. Pain attacks occurred 4–5 times a week with a median consumption of 15 mg prednisone per day. The interdisciplinary workup after several gastroenterologic, rheumatologic, radiologic, psychiatric and orthopedic consultations is shown including successful treatment steps. Clinical diagnosis revealed no systemic inflammatory disease, but confirmed extreme hypomagnesemia (0.2 mmol/l after reproducible pathological magnesium resorption tests as causative for chronic calcium pyrophosphate crystal inflammatory arthritis (pseudogout, chondrocalcinosis. Multidisciplinary treatment included application of colchicines, parenteral nutrition and magnesium substitution, antiperistaltic agents and avoidance of intolerant foods. Normalization of magnesium levels and a marked remission of joint attacks were achieved after six months with significant reduction of prednisone to 1.5 mg/day. Conclusion Despite the rarity of this condition, it is important to know that hypomagnesaemia may be associated with calcium pyrophosphate crystal inflammatory arthritis (chondrocalcinosis and that SBS patients may be prone to develop extreme hypomagnesaemia causing recurrent joint attacks without systemic inflammation.

    The myocardial blood flow was measured by the 133Xenon disappearance curve from the left ventricular wall following an injection of 133Xenon in the left coronary artery in 8 dogs without digoxin pretreatment and in 8 chronically digitalized dogs. The myocardial blood flow was significantly less (30%) in the digitalized dogs than in the dogs without pretreatment. In the digitalized dogs as well as in those without pretreatment an intravenous injection of digoxin resulted in a further significant decrease of the myocardial blood flow of about 20% and a significant increase of the coronary vascular resistance. The reduced myocardial blood flow both during acute and chronic digitalization is beleived to be of clinical importance.

    Chronic systemic inflammation is associated with increased cardiovascular mortality in patients with rheumatoid arthritis (RA). The aim of our study was to investigate association of glucose metabolism and inflammatory markers in a group of patients with rheumatoid arthritis free of other metabolic risk factors. Twenty-two premenopausal RA females (11 patients on low-dose GC (glucocorticoid therapy) and 15 age- and BMI-matched healthy females underwent the oral glucose tolerance test. The insulin sensitivity indices according Matsuda (ISI(MAT)) and Cederholm (ISI(CED)) as well as HOMA2 %S were calculated. Cytokines, lipid profile, non-esterified fatty acids (NEFA) and plasminogen activator inhibitor-1 (PAI-1) were measured in baseline blood samples. Despite elevated interleukin IL-6 and TNF alpha, glucose, insulin and C-peptide responses to oral glucose load as well as ISI(MAT), ISI(CED), PAI-1 and NEFA were comparable in both RA groups and healthy controls. HOMA2 %S correlated with disease activity. In conclusions, low-dose glucocorticoid treatment does not lead to glucose metabolism impairment in RA patients without other metabolic risk factors. Increased cardiovascular mortality and morbidity is probably due to a direct effect of systemic inflammation on myocardium and/or blood vessels.

    Viral agents have been suspected as participants of immune-mediated disorders. In the case of rheumatic diseases, the synovial joint cavity represents a secluded area of inflammation which could harbor etiological agents. We analyzed by polymerase chain reaction the possible presence of DNA from various herpes viruses in blood and synovial fluid from patients with either rheumatoid arthritis (n = 18), axial spondyloarthritis (n = 11), or osteoarthritis (n = 8). Relevant findings were as follows: DNA from varicella zoster virus was found in synovial fluid but not in blood mononuclear cells from 33 % of patients with rheumatoid arthritis and in 45 % of patients with axial spondyloarthritis but not in patients with osteoarthritis. Also, DNA from herpes simplex viruses 1 and 2 was found both in the blood and in the synovial fluid from 33 % of patients with rheumatoid arthritis. Our results indicate the occasional presence of DNA from herpes viruses in patients with rheumatoid arthritis or with axial spondyloarthritis. However, these findings might represent a parallel epiphenomenon of viral activation associated either with immunosuppressive therapy or with primary immune disturbances, rather than the etiological participation of herpes viruses in these disorders.

    Patients with chronic pain due to neuropathy or musculoskeletal injury frequently exhibit reduced alpha and increased theta power densities. However, little is known about electrical brain activity and chronic pain in patients with rheumatoid arthritis (RA). For this purpose, we evaluated power densities of spontaneous electroencephalogram (EEG) band frequencies (delta, theta, alpha, and beta) in females with persistent pain due to RA. This was a cross-sectional study of 21 participants with RA and 21 healthy controls (mean age = 47.20; SD = 10.40). EEG was recorded at rest over 5 min with participant's eyes closed. Twenty electrodes were placed over five brain regions (frontal, central, parietal, temporal, and occipital). Significant differences were observed in depression and anxiety with higher scores in RA participants than healthy controls (p = 0.002). Participants with RA exhibited increased average absolute alpha power density in all brain regions when compared to controls [F (1.39) = 6.39, p = 0.016], as well as increased average relative alpha power density [F (1.39) = 5.82, p = 0.021] in all regions, except the frontal region, controlling for depression/anxiety. Absolute theta power density also increased in the frontal, central, and parietal regions for participants with RA when compared to controls [F (1, 39) = 4.51, p = 0.040], controlling for depression/anxiety. Differences were not exhibited on beta and delta absolute and relative power densities. The diffuse increased alpha may suggest a possible neurogenic mechanism for chronic pain in individuals with RA.

    Full Text Available Psoriatic arthritis (PsA is an inflammatory arthritis whose pathogenesis is poorly understood; it is characterized by bone erosions and new bone formation. The diagnosis of PsA is mainly clinical and diagnostic biomarkers are not yet available. The aim of this work was to clarify some aspects of the disease pathogenesis and to identify specific gene signatures in paired peripheral blood cells (PBC and synovial biopsies of patients with PsA. Moreover, we tried to identify biomarkers that can be used in clinical practice.PBC and synovial biopsies of 10 patients with PsA were used to study gene expression using Affymetrix arrays. The expression values were validated by Q-PCR, FACS analysis and by the detection of soluble mediators.Synovial biopsies of patients showed a modulation of approximately 200 genes when compared to the biopsies of healthy donors. Among the differentially expressed genes we observed the upregulation of Th17 related genes and of type I interferon (IFN inducible genes. FACS analysis confirmed the Th17 polarization. Moreover, the synovial trascriptome shows gene clusters (bone remodeling, angiogenesis and inflammation involved in the pathogenesis of PsA. Interestingly 90 genes are modulated in both compartments (PBC and synovium suggesting that signature pathways in PBC mirror those of the inflamed synovium. Finally the osteoactivin gene was upregulared in both PBC and synovial biopsies and this finding was confirmed by the detection of high levels of osteoactivin in PsA sera but not in other inflammatory arthritides.We describe the first analysis of the trancriptome in paired synovial tissue and PBC of patients with PsA. This study strengthens the hypothesis that PsA is of autoimmune origin since the coactivity of IFN and Th17 pathways is typical of autoimmunity. Finally these findings have allowed the identification of a possible disease biomarker, osteoactivin, easily detectable in PsA serum.

    BACKGROUND Viral replication in blood cells with nucleuses may lead to the damage of lymphocytes genetic apparatus and the beginning of immunopathological reactions.AIM Of this investigation is to reveal the damage to peripheral blood lymphocytes (PBL)DNA in the patients with chronic liver diseases.MATERIALS AND METHODS Sixteen-ninepatients with chronic liver diseases (37 patients with chronic viral hepatitis, 2 patients with liver cirrhosis of mixed etiology (alcohol + virus G),30 women with primary biliary cirrhosis-PBC)were examined. The condition of DNA structure of PBL-was measured by the fluorescenceanalysis of DNA unwinding (FADU) technique with modification. Changes of fluorescence (in %) reflected the DNA distractions degree (thepresence of DNA single-stranded breaks and alkalinelabile sights).RESULTS AND CONCLUSION . The quantity of DNA single-stranded breaks and alkalinelabile sightsin DNA in all patients with chronic viral hepatitis .didnt differ from the control group,excluding the patients with chronic hepatitis (CH) C + G. Patients with HGV and TTV monoinfection had demonstrated the increase of the DNA single-stranded breaks PBL quantity.This fact may be connected with hypothesisabout the viruses replication in white blood cells discussed in the literature. Tendency to increase quantity of DNA PBL damages in the patients with primary biliary cirrhosis (PBC) accordingly to the alkaline phosphatase activity increase was revealed. Significant decrease of the DNA single-stranded breaks and alkalinelabile sights in the PBC patients that were treated with prednison was demonstrated. Probably, the tendency to increase the quantity of DNA singlestranded breaks and alkalinelabile sights in lymphocytes of the PBC patients was depended on the surplus of the blood bile acid content.

    In an effort to improve detection of fastidious organisms, joint fluid aspirates of pediatric patients were inoculated into BACTEC 460 aerobic blood culture bottles, in addition to cultures on solid media. Culture records for the 1988 to 1991 period were reviewed to compare the performance of both methods for the recovery of pathogens. Overall, 216 children underwent a diagnostic joint tap, and 63 specimens grew significant organisms, including Kingella kingae in 14. While both methods were comparable for recovery of usual pathogens, with a single exception, K. kingae isolates were detected by the BACTEC system only. K. kingae appears to be a more common cause of septic arthritis in children than has been previously recognized. The BACTEC blood culture system enhances the recovery of K. kingae from joint fluid and improves bacteriologic diagnosis of pediatric septic arthritis.

    Chronic Lyme arthritis that is unresponsive to antibiotic therapy is associated with an increased frequency of the HLA-DR4 specificity. To determine whether the immune response to a particular polypeptide of Borrelia burgdorferi may be associated with treatment-resistant chronic Lyme arthritis, we correlated the clinical courses and HLA-DR specificities of 128 patients with Lyme disease with their antibody responses to spirochetal polypeptides. Antibody reactivity was determined by Western blotting (immunoblotting) with sonicated whole B. burgdorferi and recombinant forms of its outer surface proteins, OspA and OspB, as the antigen preparations. Of 15 patients monitored for 4 to 12 years, 11 (73%) developed strong immunoglobulin G responses to both OspA and OspB near the beginning of prolonged episodes of arthritis, from 5 months to 7 years after disease onset. When single serum samples from 80 patients with Lyme arthritis, were tested, 57 (71%) showed antibody reactivity to recombinant Osp proteins; in contrast, none of 43 patients who had erythema migrans or Lyme meningitis (P < 0.00001) and 1 of 5 patients who had chronic neuroborreliosis but who never had arthritis (P = 0.03) showed antibody reactivity to these proteins. Among the 60 antibiotic-treated patients with Lyme arthritis, those with the HLA-DR4 specificity and Osp reactivity had arthritis for a significantly longer time after treatment than those who lacked Osp reactivity (median duration, 9.5 versus 4 months; P = 0.009); a similar trend was found for the HLA-DR2 specificity. For other HLA-DR specificities, arthritis resolved within a median duration of 2 months in both Osp-reactive and nonreactive patients. We conclude that the combination of the HLA-DR4 specificity and OspA or OspB reactivity is associated with chronic arthritis and the lack of a response to antibiotic therapy. Images PMID:7685738

    Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disease primarily involving the joint synovium. RA is a systemic disease which has many known extra-articular manifestations. We present a unique case of a patient with long standing RA who presented with a primary complaint of chest and back pain. Echocardiography revealed borderline normal left ventricular function and a large pericardial effusion with the finding of elevated intrapericardial pressure suspicious for cardiac tamponade. Infectious workup was all found to be negative. The presence and elevation of anti-cyclic citrullinated peptide antibody, rheumatoid factor and C-reactive protein (CRP) confirmed the patient was having an active flare-up of RA. It was determined that this flare-up was the cause of the cardiac tamponade. A pericardiocentesis was performed and 850 mL of bloody fluid was drained. The patient remained stable following the pericardiocentesis. At his follow-up visit, repeat echocardiogram showed no signs for pericardial effusion. Although there has been extensive study of RA, there are only a few documented cases noting the occurrence of cardiac tamponade in these patients. Therefore, it is important for the clinician to be aware of and recognize this potentially serious cardiac outcome associated with a common rheumatologic condition.

    Diabetic patients with increased plasma glucose concentrations may develop cerebral symptoms of hypoglycemia when their plasma glucose is rapidly lowered to normal concentrations. The symptoms may indicate insufficient transport of glucose from blood to brain. In rats with chronic hyperglycemia the maximum glucose transport capacity of the blood-brain barrier decreased from 400 to 290 micromoles per 100 grams per minute. When plasma glucose was lowered to normal values, the glucose transport rate into brain was 20 percent below normal. This suggests that repressive changes of the glucose transport mechanism occur in brain endothelial cells in response to increased plasma glucose.

    Full Text Available This study presents effects of intravenous laser blood irradiation (ILBI in a transient immunodeficiency patient with juvenile idiopathic arthritis (JIA treated with an interleukin-6 receptor inhibitor (Tocilizumab. Biological agents induce JIA remission, but some patients do not respond favorably to this final therapeutic line of defense. ILBI was performed in a 16-year-old male patient, with JIA and transient immunodeficiency. When ILBI was introduced, the patient was receiving disease-modifying drugs, steroids, tocilizumab, and physical therapy. Because the disease was not well controlled, ILBI was applied in addition to other ongoing therapies. The patient underwent 1 session daily, and 10 successive sessions per month, repeated every 3 months, for 7 months. Patient evaluation was performed before ILBI was started and at 3, 6, 9, and 12 months after ILBI initiation, using the ACR Pediatric response. The outcome was evaluated using Pediatric 50, 70, and 90 responses and compared to initial status, after 3, 6, 9, and 12 months. At the end of study, the titre of IgA and IgG levels returned to normal. Synergistic anti-inflammatory effect of ILBI was evident, if applied additionally in combination with tocilizumab, in a patient with a therapy-resistant severe form of JIA and related subacute transient immunodeficiency.

    Mycoplasma salivarium is a rare agent of septic arthritis in immunocompromised patients. We report a case of septic arthritis due to Mycoplasma salivarium in a patient with B-cell chronic lymphocytic leukemia who underwent chemotherapy with rituximab and bendamustin. Therapy of arthritis due to Mycoplasma salivarium is difficult because there are almost no susceptibility data available. The present case illustrates that antimicrobial susceptibility of Mycoplasma strains is not necessarily predictable and that antibiotic therapy should therefore be guided by in vitro susceptibility testing.

    Abstract Trial Design: In the double-blind, randomized, controlled trial, we aimed to evaluate the effects of compound tufuling oral liquid (CoTOL) on serum uric acid (sUA) levels and recurrence of acute gouty arthritis in intercritical and chronic gout treatment. Methods: A total of 210 patients with gout were screened from 8 hospitals to observe the sUA and acute gouty arthritis recurrence rate-reducing effects of CoTOL in intercritical and chronic gout during a 12-week treatment. We treated 139 and 71 patients with CoTOL and the placebo, respectively, and evaluated their sUA levels, acute gouty arthritis recurrence rate, and adverse events at week 0, 6, and 12. Results: Twenty-five and 12 patients in the treatment and control groups, respectively, had interrupted treatments, whereas 114 and 59 cases, respectively, completed their treatments. At the end of the 12-week treatment, the average decrease in sUA was 74.26 (95% confidence interval [CI]: 56.74–91.77 μmol/L) and 28.81 μmol/L (95% CI: 4.91–52.71 μmol/L) in the treatment and control groups, respectively (P = 0.004). The average decrease rate of sUA was 12.76% (95% CI: 9.82%–15.70%) and 4.57% (95% CI: 0.42%–8.71%) in the treatment and control groups, respectively (P = 0.004), and the gouty arthritis recurrence rate of the treatment group was lower than that of the control group (from week 6 to 12, 21.93% and 50.88% in the treatment and control group, respectively, P leucopenia incidences were observed in the treatment group than those in the control group (3/139 vs. 7/71, respectively, P = 0.033). Conclusion: CoTOL reduced sUA levels and effectively prevented acute arthritis recurrence in intercritical and chronic gout without serious adverse events. PMID:28296744

    Objectives To investigate the association between rheumatoid arthritis (RA) and periodontitis with special emphasis on the role of antirheumatic drugs in periodontal health. Design Prospective follow-up study. Patients with early untreated RA and chronic active RA were examined at baseline and 16 months later. Controls were examined once. Settings and participants The study was conducted in Finland from September 2005 to May 2014 at the Helsinki University Hospital. Overall, 124 participants were recruited for dental and medical examinations: 53 were patients with early disease-modifying antirheumatic drug (DMARD) naїve RA (ERA), 28 were patients with chronic RA (CRA) with insufficient response to conventional DMARDs. After baseline examination, patients with ERA started treatment with synthetic DMARDs and patients with CRA with biological DMARDs. Controls were 43 age-matched, gender-matched and community-matched participants. Outcome measures Degree of periodontitis (defined according to the Center for Disease Control and Prevention and the American Academy of Periodontology). Prevalence of periodontal bacteria (analysed from plaque samples), clinical rheumatological status by Disease Activity Score, 28-joint count (DAS28), function by Health Assessment Questionnaire (HAQ) and treatment response by European League Against Rheumatism (EULAR) criteria. Results Moderate periodontitis was present in 67.3% of patients with ERA, 64.3% of patients with CRA and 39.5% of control participants (p=0.001). Further, patients with RA had significantly more periodontal findings compared with controls, recorded with common periodontal indexes. In the re-examination, patients with RA still showed poor periodontal health in spite of treatment with DMARDs after baseline examination. The prevalence of Porphyromonas gingivalis was higher in patients with ERA with periodontal probing depth ≥4 mm compared with patients with CRA and controls. Antirheumatic medication did not seem

    Family studies have provided overwhelming evidence for an underlying genetic component to psoriasis. Toll-like receptors (TLRs) are key transmembrane proteins in both the innate and adaptive immune responses which are known to be integral processes in psoriasis. Recent functional studies support this notion having suggested a role for TLR4 in the pathogenesis of psoriasis. Furthermore a missense polymorphism in the TLR4 gene has been associated with a number of autoimmune conditions, including Crohn diseases, making TLR4 a viable candidate gene for investigation. The aim of this study was to investigate polymorphisms across the TLR4 region with a high-density single nucleotide polymorphism (SNP) panel in a large cohort of patients with chronic plaque type psoriasis. Twenty SNPs were successfully genotyped using Sequenom iPLEX Gold platform in 2826 UK chronic plaque type psoriasis patients including subgroup data on presence of confirmed psoriatic arthritis (n = 1839) and early-onset psoriasis (n = 1466) was available. Allele frequencies for psoriasis patients were compared against imputed Wellcome Trust Case Control Consortium controls (n = 4861). Significant association was observed between a missense variant rs4986790 of TLR4 (Asp229Gly) and plaque type psoriasis (p = 2 × 10(-4)) which was also notable in those with psoriatic arthritis (p = 2 × 10(-4)) and early-onset psoriasis (p = 8 × 10(-4)). We present data suggestive of an association between a functional variant and an intronic variant of TLR4 and chronic plaque type psoriasis and psoriatic arthritis. However, validation of this association in independent cohorts will be necessary.

    Chronic kidney disease (CKD) may affect excretion and metabolism of vitamins but data for dogs are limited. In this study, blood vitamin levels were investigated in 19 dogs with chronic renal failure. High performance liquid chromatography was used to quantify retinol, retinyl esters, tocopherol, thiamine, riboflavin, pyridoxal-5'-phosphate, ascorbic acid and 25-hydroxycholecalciferol concentrations, whereas cobalamin, folate, biotin and pantothenic acid were measured by microbiological methods. Levels of retinol, retinyl palmitate, ascorbic acid, and vitamins B1, B2 and B6 were increased compared to healthy dogs. Dogs with CKD showed decreased concentrations of 25-hydroxycholecalciferol and folate. Alpha-tocopherol, biotin, pantothenate and cobalamin levels were not significantly different between controls and dogs with CKD. Whether lower vitamin D and folate concentrations in dogs with CKD justify supplementation has to be evaluated in future studies.

Objective The aim of the study was to establish if there was any improvement of disease activity parameters after four weeks of physical and spa treatment. METHOD We compared morning stiffness, tender and swollen joint count, body pain level and Disease Activity Score 28 (DAS-28 in patients with rheumatoid and psoriatic arthritis, and assessed the effect of physical and spa treatment on those parameters. The research encompassed 109 patients: 69 with rheumatoid arthritis (RA group and 40 with psoriatic arthritis (PA group. They were from Norway, staying for four weeks in June-September 2003. The groups served as their own controls - "one group pre-test post test" study. Disease activity measurement was made twice: at the beginning and at the end of treatment. The therapeutic set consisted of mud applications, kinesitherapy, mineral water pool and electrotherapy. Results At the beginning there was no significant difference in observed disease activity parameters between patients with rheumatoid and psoriatic arthritis (p>0.05. After four weeks of physical and spa treatment disease activity was significantly reduced in all observed parameters in both groups: morning stiffness (p<0.001 RA+PA, tender joint count (p<0.01 RA+PA, swollen joint count (p<0.01 RA; p<0.05 PA, body pain (p<0.01 RA+PA and DAS-28 score (p<0.01 RA+PA. Conclusion Physical and spa treatment, together with climatic factors in Igalo, lead to a significant reduction of disease activity parameters of patients suffering from rheumatoid arthritis and psoriatic arthritis. .

    Chronic graft versus host disease (GVHD) is a less frequently seen disease that occurs post solid organ or bone marrow transplantation. Chronic GVHD occurring post blood transfusion is an even more uncommon disease. It can present either as a lichenoid disease or as a sclerodermatous disease involving multiple systems. In this article, we report a case of chronic graft versus host reaction occurring in skin secondary to blood transfusion.

    Rheumatoid arthritis (RA) is a chronic inflammatory destructive disease involving the joint and characterized by T-lymphocyte accumulation within the synovial compartment. It is dominated by the presence of macrophages, plasma cells and synovial fibroblasts which are the main pathogenic factors leading to the destruction of bone and cartilage. The survival of these cells may be promoted by inadequate apoptosis leading to synovial hyperplasia. So, the aim of the present study was to evaluate the apoptosis levels before and after induction of apoptosis using anti-Fas mAb, both in peripheral blood (PB) and synovial fluid (SF) infiltrating mononuclear cells (MCs) of patients with RA. CD4+ T cell subsets and cell survival assays were also done to investigate correlations between these parameters. The study was conducted on 15 patients with RA, 10 individual volunteers as a control group and 10 patients with osteoarthritis (OA) as a control group for SF evaluations (have defective Fas expression on their cells). Results of this work revealed that in vitro induction of apoptosis by anti-Fas mAb resulted in increase of: percent (%) reduction of cell viability in PBMCs and SFMCs, % reduction of CD4+ T cell subsets and apoptotic cell % in all studied groups than before induction. The increase in the three parameters is only significant in SF of RA group compared to PB while it is non significant in OA group due to the defective Fas expression on OA cells. Our results also showed a significant positive correlation between CD4+ T cell and viability percentages before induction of apoptosis in SF of RA and between apoptosis levels and CD4+ T cell percentage after induction of apoptosis in the SF of RA group. In conclusion, activated T cells infiltrating SF of RA patients have functional Fas antigen which enable them to undergo in vitro apoptosis using anti-Fas mAb. The cytotoxicity of which is more specific to local lesion such as SF of RA patients suggesting that local

    In children with Juvenile Chronic arthritis (JCA), temporomandibular joint involvement may lead to disturbances in dentofacial growth and mandibular function. The aim of this thesis was to study the dentofacial morphology, temporomandibular joint destruction and mandibular function in JCA children, and the relation between these factors. The intention was also to make a longitudinal study of the changes in facial morphology during growth and during treatment with functional appliances. Thirty-five JCA children, 12 boys and 23 girls, aged 7-16 years (mean 11.2 years), and the control groups, with either normal or distal occlusion, were studied by means of panoramic radiographs, lateral cephalograms, study casts, recordings of signs and symptoms of temporomandibular disorders (TMD), bite force and chewing characteristics. A method to evaluate the condylar height on panoramic radiographs was developed. Panoramic radiographs are found to be reliable for evaluation of the condylar height, provided the same panoramic machine is used. The dentofacial morphology in JCA children is characterized by a smaller, more retrognathic and steeper inclined mandible compared to that of healthy children with ideal occlusion. Compared to healthy children with distal occlusion, no difference in mandibular retrognathia could be demonstrated but the JCA children showed a smaller, more steeply inclined mandible. The presence and extent of condylar lesions play a significant role in the development of the facial morphology and also contribute to the facial heterogeneity among JCA children. During growth the JCA children without radiographically visible condylar lesions showed a growth pattern resembling that of healthy children with normal occlusion, while children with condylar lesions showed aggravation of the mandibular retrognathia and a tendency towards a backward-rotating growth pattern. The chewing movements in JCA children are restricted by the disease and by the presence of

    Although strong epidemiologic evidence suggests an important role for adaptive immunity in the pathogenesis of polyarticular juvenile rheumatoid arthritis (JRA), there remain many aspects of the disease that suggest equally important contributions of the innate immune system. We used gene expression arrays and computer modeling to examine the function in neutrophils of 25 children with polyarticular JRA. Computer analysis identified 712 genes that were differentially expressed between patients and healthy controls. Computer-assisted analysis of the differentially expressed genes demonstrated functional connections linked to both interleukin (IL)-8- and interferon-gamma (IFN-gamma)-regulated processes. Of special note is that the gene expression fingerprint of children with active JRA remained essentially unchanged even after they had responded to therapy. This result differed markedly from our previously reported work, in which gene expression profiles in buffy coats of children with polyarticular JRA reverted to normal after disease control was achieved pharmacologically. These findings suggest that JRA neutrophils remain in an activated state even during disease quiescence. Computer modeling of array data further demonstrated disruption of gene regulatory networks in clusters of genes modulated by IFN-gamma and IL-8. These cytokines have previously been shown to independently regulate the frequency (IFN-gamma) and amplitude (IL-8) of the oscillations of key metabolites in neutrophils, including nicotinamide adenine dinucleotide (phosphate) (NAD(P)H) and superoxide ion. Using real-time, high-speed, single-cell photoimaging, we observed that 6/6 JRA patients displayed a characteristic defect in 12% to 23% of the neutrophils tested. Reagents known to induce only frequency fluctuations of NAD(P)H and superoxide ion induced both frequency and amplitude fluctuations in JRA neutrophils. This is a novel finding that was observed in children with both active (n = 4) and

    Full Text Available Purpose. This study explored the effect of autologous blood injection (with ultrasound guidance to the elbows of patients who had radiologically assessed degeneration of the origin of extensor carpi radialis brevis and failed cortisone injection/s to the lateral epicondylitis. Methods. This prospective longitudinal series involved preinjection assessment of pain, grip strength, and function, using the patient-rated tennis elbow evaluation. Patients were injected with blood from the contralateral limb and then wore a customised wrist support for five days, after which they commenced a stretching, strengthening, and massage programme with an occupational therapist. These patients were assessed after six months and then finally between 18 months and five years after injection, using the patient-rated tennis elbow evaluation. Results. Thirty-eight of 40 patients completed the study, showing significant improvement in pain; the worst pain decreased by two to five points out of a 10-point visual analogue for pain. Self-perceived function improved by 11–25 points out of 100. Women showed significant increase in grip, but men did not. Conclusions. Autologous blood injection improved pain and function in a worker’s compensation cohort of patients with chronic lateral epicondylitis, who had not had relief with cortisone injection.

    Chronic kidney disease (CKD) is progressive loss of renal function associated among others with increased intracellular calcium concentration. The purpose of this study was to identify the effects of CKD on cell membrane properties such as human red blood cell Ca(2+) ATPase activity, lymphocyte plasma membrane P2X(7) receptor expression and function. This could help us in elucidating the origin of increased calcium concentration in blood cells. We found out Ca(2+) ATPase activity is decreased in early stage CKD patients resulting in altered calcium removal from cytoplasm. By means of flow cytometry we assessed that P2X(7) receptor expression on lymphocyte membrane is 1.5 fold increased for CKD patients. Moreover, we detected an increased uptake of ethidium bromide through this receptor in CKD at basal conditions. It means CKD lymphocyte membranes contain more receptors which are more permeable thus allowing increased calcium influx from extracellular milieu. Finally, we can state alterations in blood cell membranes are closely linked to CKD and may be responsible for intracellular calcium accumulation.

    A patient with juvenile rheumatoid arthritis and chronic iritis is reported with intraocular pressure near 30 mm Hg and previous episodes of intraocular pressure as high as 50 mm Hg despite maximally tolerated medical therapy. Because of the potential risk involved with a full-thickness filtration procedure, it was decided that a nonpenetrating deep sclerectomy would be appropriate, followed by placement of a collagen glaucoma drainage device to maintain aqueous outflow. Immediately postoperatively, intraocular pressure was stabilized. At 24 months postoperatively, intraocular pressure was well controlled at 15 mm Hg with patient receiving only Lotemax. No significant complications were noted at any point in the postoperative course. Because of the patient's predisposition for serious complications frequently associated with trabeculectomy, nonpenetrating deep sclerectomy with the collagen glaucoma drainage device was an effective alternative for this patient.

    Disorders in mental functioning are indicated as the cause of all connective tissue diseases and also as their consequences. That is why psychologist's help may be very important for patients with rheumatoid arthritis. Psychological observations of patients with chronic systemic connective tissue diseases show a number of negative emotional states such as fear, anxiety, insecurity, depressed mood, depression, impatience, anger and a sense of loss These patients constantly experience pain of varying intensity and location. In many of them progressive disease leads to the advancement of mental crisis. Methods of psychological therapy must be focused on strenghtening mental resilience and helping in surviving mental crisis. Psychological therapy should concentrate on raising self-esteem, training interpersonal skills and teaching relaxation techniques to cope better with pain and suffering. Psychological therapy should support the patient in struggling with the problems caused by the disease and developing ways of adapting to life with the disease.

    Full Text Available Rheumatoid arthritis (RA is a chronic, systematic autoimmune disease that mainly affects joints and bones. Although the precise etiology is still unknown, Th17 cell is being recognized as an important mediator in pathogenesis of RA. VSTM1-v2 is a novel cytokine which has recently been reported to promote the differentiation of Th17 cells. This study is performed to study whether VSTM1-v2 can be recognized as a biomarker of RA, and is correlated to IL-17 expression. We obtained peripheral blood mononuclear cells (PBMCs from 40 patients with RA and 40 age- and sex-matched healthy controls by standard Ficoll-Paque Plus density centrifugation. The mRNA expression levels of VSTM1-v2 and IL-17A in PBMCs were detected by real time-PCR. Disease activity parameters of RA were measured by routine methods. Our results showed that VSTM1-v2 mRNA expression in PBMCs from RA patients was significantly increased in comparison of that in healthy individuals. The VSTM1-v2 mRNA expression level was positively correlated with IL-17A mRNA expression level, DAS28, CRP and ESR, but was not correlated to RF, Anti-CCP or ANA. VSTM1-v2 might be a biomarker of RA and a novel factor in the pathogenesis of RA.

    Chronic arthritis (CA) is an unusual condition in childhood-onset systemic lupus erythematosus (cSLE) and data in children is very limited. The aim of the study is to assess CA in a large population of cSLE patients, in a multicenter cross-sectional study including 852 cSLE patients followed in ten Pediatric Rheumatology referral services in state of São Paulo, Brazil. CA was observed in 32/852 (3.7 %) cSLE patients mostly in hands and ankles. Chronic monoarthritis was diagnosed in four cSLE patients, oligoarthritis in nine and polyarthritis in 19. In the latter group, six had rhupus syndrome. Two oligoarticular patients had Jaccoud's arthropathy. CA was an isolated manifestation observed at disease onset in 13/32 (41 %) cSLE patients, and juvenile idiopathic arthritis (JIA) was the first diagnosis in 18/32 (56 %). The comparison of last visit of patients with CA and without this manifestation revealed higher frequency of splenomegaly (28 vs. 11 %, p = 0.002). The median of SLICC/ACR-DI score [1(0-9) vs. 0(0-7), p = 0.003] was significantly higher in CA patients compared to patients without this manifestation, likewise the frequency of musculoskeletal damage (31 vs. 9 % p = 0.001). Frequencies of treatment with nonsteroidal anti-inflammatory drugs (75 vs. 26 %, p < 0.0001), hydroxychloroquine sulfate (87 vs. 59 %, p = 0.001) and methotrexate (47 vs. 22 %, p = 0.001) were significantly higher in CA patients. This large multicenter study allowed us to characterize CA as a rare and early manifestation of cSLE, frequently mimicking JIA at disease onset. It is predominantly polyarticular, involving more often hands and ankles and it is associated with significant musculoskeletal accrual damage.

    Elucidation of factors regulating glucocorticoid (GC) sensitivity is required for the development of "steroid-sparing" therapies for chronic inflammatory diseases, including rheumatoid arthritis (RA). Accumulating evidence suggests that macrophage migration inhibitory factor (MIF) counterregulates the GC-induction of anti-inflammatory mediators, including mitogen-activated protein kinase phosphatase 1 (MKP1), a critical mitogen-activated protein kinase signaling inhibitor. This observation has yet to be extended to human disease; the molecular mechanisms remain unknown. We investigated NURR1, a GC-responsive transcription factor overexpressed in RA, as a MIF signaling target. We reveal abrogation by recombinant MIF (rMIF) of GC-induced MKP1 expression in RA fibroblast-like synoviocytes (FLS). rMIF enhanced NURR1 expression, artificial NBRE (orphan receptor DNA-binding site) reporter transactivation, and reversed GC-inhibition of NURR1. NURR1 expression was reduced during experimental arthritis in MIF-/- synovium, and silencing MIF reduced RA FLS NURR1 mRNA. Consistent with NBRE identification on the MKP1 gene, MKP1 mRNA was reduced in FLS that ectopically express NURR1, and silencing NURR1 enhanced MKP1 mRNA in RA FLS. rMIF enhanced NBRE binding on the MKP1 gene, and the absence of the NBRE prevented NURR1-repressive effects on basal and GC-induced MKP1 transactivation. This study defines NURR1 as a novel MIF target in chronic inflammation and demonstrates a role for NURR1 in regulating the anti-inflammatory mediator, MKP1. We propose a MIF-NURR1 signaling axis as a regulator of the GC sensitivity of MKP1.

    The associations between the lumbar and femoral bone mineral and several body constitutional, lifestyle, and disease related variables were studied in 111 children with juvenile chronic arthritis (JCA) by factor and multiple linear regression analyses. In addition to the measurement of bone mineral density (BMD), bone width and bone mineral volumetric density (BMDvol) were determined by dual-x-ray absorptiometry (DXA). Factor analysis of 13 explanatory variables yielded six non-correlating factors, named as body size, physical activity, calcium intake, glucocorticoids, disease duration, and disease activity. These six factors were used as new variables to explain BMD, BMDvol, and bone width by multiple linear regression analyses. These showed body size, physical activity, and calcium intake as significant positive and disease activity and glucocorticoids as significant negative determinants of BMD in JCA. The analyses revealed also considerable differences in the relationships between factors and BM Dvol or bone width.

  8. Chronic intestinal ischaemia: measurement of the total splanchnic blood flow.

    A redundant collateral network between the intestinal arteries is present at all times. In case of ischaemia in the gastrointestinal tract, the collateral blood supply can develop further, thus accommodating the demand for oxygen even in the presence of significant stenosis or occlusion of the intestinal arteries without clinical symptoms of intestinal ischaemia. Symptoms of ischemia develop when the genuine and collateral blood supply no longer can accommodate the need for oxygen. Atherosclerosis is the most common cause of obliteration in the intestinal arteries. In chronic intestinal ischaemia (CII), the fasting splanchnic blood flow (SBF) is sufficient, but the postprandial increase in SBF is inadequate and abdominal pain will therefore develop in relation to food intake causing the patient to eat smaller meals at larger intervals with a resulting weight loss. Traditionally, the CII-diagnosis has exclusively been based upon morphology (angiography) of the intestinal arteries; however, substantial discrepancies between CII-symptoms and the presence of atherosclerosis/stenosis in the intestinal arteries have been described repeatedly in the literature impeding the diagnosis of CII. This PhD thesis explores a method to determine the total SBF and its potential use as a diagnostic tool in patients suspected to suffer from CII. The SBF can be measured using a continuous infusion of a tracer and catheterisation of a hepatic vein and an artery. By measuring the SBF before and after a standard meal it is possible to assess the ability or inability to enhance the SBF and thereby diagnosing CII. In Study I, measurement of SBF was tested against angiography in a group of patients suspected to suffer from CII due to pain and weight loss. A very good agreement between the postprandial increase in SBF and angiography was found. The method was validated against a well-established method independent of the hepatic extraction of tracer using pAH in a porcine model (study II

    Bacteria, viruses, fungi, and parasites can all cause arthritis of either acute or chronic nature, which can be divided into infective/septic, reactive, or inflammatory. Considerable advances have occurred in diagnostic techniques in the recent decades resulting in better treatment outcomes in patients with infective arthritis. Detection of emerging arthritogenic viruses has changed the epidemiology of infection-related arthritis. The role of viruses in the pathogenesis of chronic inflammatory arthritides such as rheumatoid arthritis is increasingly being recognized. We discuss the various causative agents of infective arthritis and emphasize on the approach to each type of arthritis, highlighting the diagnostic tests, along with their statistical accuracy. Various investigations including newer methods such as nucleic acid amplification using polymerase chain reaction are discussed along with the pitfalls in interpreting the tests.

  10. Blood Biomarkers of Chronic Inflammation in Gulf War Illness.

    Gerhard J Johnson

    Full Text Available More than twenty years following the end of the 1990-1991 Gulf War it is estimated that approximately 300,000 veterans of this conflict suffer from an unexplained chronic, multi-system disorder known as Gulf War Illness (GWI. The etiology of GWI may be exposure to chemical toxins, but it remains only partially defined, and its case definition is based only on symptoms. Objective criteria for the diagnosis of GWI are urgently needed for diagnosis and therapeutic research.This study was designed to determine if blood biomarkers could provide objective criteria to assist diagnosis of GWI.A surveillance study of 85 Gulf War Veteran volunteers identified from the Department of Veterans Affairs Minnesota Gulf War registry was performed. All subjects were deployed to the Gulf War. Fifty seven subjects had GWI defined by CDC criteria, and 28 did not have symptomatic criteria for a diagnosis of GWI. Statistical analyses were performed on peripheral blood counts and assays of 61 plasma proteins using the Mann-Whitney rank sum test to compare biomarker distributions and stepwise logistic regression to formulate a diagnostic model.Lymphocyte, monocyte, neutrophil, and platelet counts were higher in GWI subjects. Six serum proteins associated with inflammation were significantly different in GWI subjects. A diagnostic model of three biomarkers-lymphocytes, monocytes, and C reactive protein-had a predicted probability of 90% (CI 76-90% for diagnosing GWI when the probability of having GWI was above 70%.The results of the current study indicate that inflammation is a component of the pathobiology of GWI. Analysis of the data resulted in a model utilizing three readily measurable biomarkers that appears to significantly augment the symptom-based case definition of GWI. These new observations are highly relevant to the diagnosis of GWI, and to therapeutic trials.

    A serologic study of Chagas disease was performed in 110 patients submitted to chronic hemodialisis and blood transfusions. Immunofluorescence antibody testing (IgG and IgM) was positive in 6 out of 62 patients receiving multiple blood transfusions (9.7%), but negative in all 48 subjects without transfusions. Thus, repeated blood transfusion is a significant risk for T cruzi infection in chronic hemodialized patients.

    Pro-inflammatory cytokine release (IL-8, IL-6, TNF-α, IL-1β) by peripheral blood neutrophils, isolated from periodontitis patients (before/after therapy) and matched controls, was determined after 18 h culture in the presence/absence of Escherichia coli LPS, opsonised Staphylococcus aureus, heat-killed Fusobacterium nucleatum and Porphyromonas gingivalis. All cultures demonstrated differences in the amounts of each cytokine detected (P IL-6 > TNF-α = IL-1β). Median cytokine release from unstimulated patient neutrophils was consistently, but non-significantly, higher than from control cells. Stimulated cytokine release from untreated patient neutrophils was also consistently higher than from control cells. This hyper-reactivity was significant for all tested cytokines when data for all stimuli were combined (P TNF-α), opsonised S. aureus (IL-8, TNF-α, IL-1β) and P. gingivalis (IL-8, IL-1β). Cytokine production by patient neutrophils did not reduce following successful non-surgical periodontal therapy and, except for responses to F. nucleatum, the cytokine hyper-reactivity detected pre-therapy was retained. These data demonstrate that chronic periodontitis is characterised by neutrophils that constitutively exhibit cytokine hyper-reactivity, the effects of which could modulate local and systemic inflammatory-immune responses and influence the risk and severity of periodontitis-associated systemic inflammatory diseases.

    Full Text Available Objective. To compare efficacy of different glucocorticoid (GC medication forms in protracted and chronic gout arthritis. Material and methods. 59 pts with tophaceous gout (crystal-verified diagnosis and arthritis of three and more joints lasting more than a months in spite of treatment with sufficient doses of nonsteroidal anti-inflammatory drugs were included. Median age of pts was 56 [48;63], median disease duration — 15,2 years [7,4;20], median swollen joint count at the examination — 8 [5; 11]. The patients were randomized into 2 groups. Methylprednisolone (MP 500 mg/day iv during 2 days and placebo im once was administered in one of them, betamethasone (BM 7 mg im once and placebo iv twice — in the other. Results. Number of pts with full resolution of arthritis, recurrent exacerbation, insufficient arthritis resolution or clinically insignificant response was comparable in both groups. More rapid decrease of pain at moving was achieved during the first 2-3 days after GC administration in pts with full resolution of arthritis (p=0,03 in group receiving MP in comparison with BM. At day 14 joint damage measures did not differ between groups. Conclusion. Efficacy of short-term glucocorticoid administration does not depend on mode of administration and GC medication form (methylprednisolone 500 mg/day iv during 2 days or betamethasone 7 mg im once.

    1990-12-01

    Full Text Available Twenty-four patients with rheumatoid arthritis (RA and 20 normal controls were examined for the ability of their peripheral blood B cells to produce interleukin 1 (IL-1 with or without lipopolysaccharide (LPS. B cells were purified from peripheral blood by negative selection methods (i.e., removal of adherent cells and sheep red blood cell rosette-forming cells, followed by treatment with monoclonal antibodies (OKT3 and OKM1 and complement. The amount of IL-1 in B cell culture supernatants (SN was measured by thymocyte and fibroblast proliferation assays and an enzyme-linked immunosorbent assay for IL-1 alpha and beta. As a group, cultured B cells from patients with RA, both spontaneously and when stimulated with LPS, produced higher levels of IL-1 than those from normal controls. IL-1 production by RA B cells with LPS had a weak but positive correlation with disease activity. Moreover, RA B cell culture SN with elevated levels of IL-1 had a synergistic effect on the growth of anti-human IgM (anti-mu stimulated B cells. In separate experiments, the growth of RA B cells was significantly promoted by IL-1 beta both with and without anti-mu stimulation. These results suggest that B cell-derived IL-1 may be involved in the B cell clonal expansion of RA through its own activity as a B cell stimulatory factor.

    Human immunodeficiency virus (HIV) and methamphetamine (METH) dependence are independently associated with neuronal dysfunction. The coupling between cerebral blood flow (CBF) and neuronal activity is the basis of many task-based functional neuroimaging techniques. We examined the interaction between HIV infection and a previous history of METH dependence on CBF within the lenticular nuclei (LN). Twenty-four HIV-/METH-, eight HIV-/METH+, 24 HIV+/METH-, and 15 HIV+/METH+ participants performed a finger tapping paradigm. A multiple regression analysis of covariance assessed associations and two-way interactions between CBF and HIV serostatus and/or previous history of METH dependence. HIV+ individuals had a trend towards a lower baseline CBF (-10%, p = 0.07) and greater CBF changes for the functional task (+32%, p = 0.01) than HIV- subjects. Individuals with a previous history of METH dependence had a lower baseline CBF (-16%, p = 0.007) and greater CBF changes for a functional task (+33%, p = 0.02). However, no interaction existed between HIV serostatus and previous history of METH dependence for either baseline CBF (p = 0.53) or CBF changes for a functional task (p = 0.10). In addition, CBF and volume in the LN were not correlated. A possible additive relationship could exist between HIV infection and a history of METH dependence on CBF with a previous history of METH dependence having a larger contribution. Abnormalities in CBF could serve as a surrogate measure for assessing the chronic effects of HIV and previous METH dependence on brain function.

    Objective To establish whether the analysis of whole blood gene expression can be useful in predicting or monitoring response to anti-TNF therapy in RA. Methods Whole blood RNA (PAXgene) was obtained at baseline and 14 weeks on three independent cohorts with a combined total of 250 patients with rheumatoid arthritis beginning anti-TNF therapy. We employed an approach to gene expression analysis that is based on gene expression “modules”. Results Good and Moderate Responders by EULAR criteria exhibited highly significant and consistent changes in multiple gene expression modules using a hyper geometric analysis after 14 weeks of therapy. Strikingly, non responders exhibited very little change in any modules, despite exposure to TNF blockade. These patterns of change were highly consistent across all three cohorts, indicating that immunological changes after TNF treatment are specific to the combination of both drug exposure and responder status. In contrast, modular patterns of gene expression did not exhibit consistent differences between responders and non-responders at baseline in the three cohorts. Conclusions These data provide evidence that using gene expression modules related to inflammatory disease may provide a valuable method for objective monitoring of the response of RA patients who are treated with TNF inhibitors.

However, certain complications, such as alloimmunization to red blood cells, can create challenges in the management of those patients. Routine phenotyping of blood recipients and the use of phenotype-matched blood units for transfusion have been useful to lower the occurrence of red cell alloantibodies in chronically transfused individuals. Nevertheless, extensive phenotyping is expensive, laborious, and cannot be performed in certain situations. The molecular understanding of blood groups has enabled the design of assays that may be used to better guide matched red blood cell transfusions. This review summarizes key findings related to red cell alloimmunization, the already identified and potential future benefits of blood group genotyping, and how molecular typing is being incorporated in the blood bank's routine to improve clinical and long-term outcomes in chronically transfused patients.

    Anti-cyclic citrullinated peptide (anti-CCP) antibody is highly specific for diagnosing rheumatoid arthritis (RA). Cigarette smoking is a lifestyle and environmental factor associated with anti-CCP production and is strongly associated with chronic obstructive pulmonary disease (COPD). This study assessed levels of anti-CCP antibodies and rheumatoid factor (RF) among patients with RA and COPD. The study sample comprised 63 patients with RA and 70 patients with COPD, all of whom underwent assessment of anti-CCP antibody and RF levels. Testing revealed that 54.2% of RA patients and 0% of COPD patients were positive for anti-CCP antibodies. Additionally, 82.5% of RA patients and 42% of COPD patients were positive for RF. Among RA patients, levels of anti-CCP antibodies were higher among smokers than among nonsmokers (242.7 ± 128.3 vs. 68.1 ± 112.1, P < 0.001). COPD patients had low titers of RF but were negative for anti-CCP antibodies. The presence of anti-CCP antibodies was a reliable serologic marker in RA diagnosis and was associated with cigarette smoking.

    Full Text Available Osteoporosis is a well-known extra-articular complication in rheumatoid arthritis (RA. The chronic corticosteroid treatment, the functional impairment associated with RA and the disease itself appear to be the most relevant determinants. Most of the previous studies involved postmenopausal women, in whom the estrogenic deficiency might amplify the negative effect towards bone of both RA and corticosteroid therapy. We decided to evaluate bone health in a cohort of premenopausal RA patients. The study population includes 47 premenopausal women attending our outpatient clinic for RA and twice as many healthy age-matched control women selected from the hospital personnel. The bone density at the spine and femoral neck were significantly lower in patients with RA as compared with controls. When spine bone mineral density (BMD values were adjusted for the cumulative glucocorticoid (GC dose alone and for the cumulative GC dose plus body mass index (BMI the mean differences between two groups decreased but they remained statistically significant. We found no difference when the spine BMD was adjusted for cumulative GC dose, BMI and health assessment questionnaire. The difference in femoral neck BMD remained statistically significant also after all the same adjustments. In conclusion, our study shows that a BMD deficiency is frequent also in premenopausal women affected by RA, especially at femoral site and that the main determinants of this bone loss are not only the disease-related weight loss, corticosteroid therapy and functional impairment, but also the systemic effects of the disease itself.

    The treatment and care of patients with rheumatoid arthritis (RA) is complex and various health professionals with different areas of expertise may be involved. The objective of this article is to review the treatments and their efficacy as provided by health care professionals in RA care. The requirements for further research in this area are formulated. To achieve better effects of treatment it is necessary to improve the coordination of services as provided by the different specialists. The important roles of the patients themselves in the care and management of the disease are emphasized, as well as the roles of the informal caregivers such as a spouse or other family members and friends and the role of patient societies. The possible role of the International Classification of Functioning, Disability and Health (ICF) to improve the communication and facilitate the coordination among health professionals and between patients and health professionals is mentioned. The topics presented in this article may encourage further discussion and research, particularly concerning the effects of the treatments as provided by allied health professionals. Health professionals play an important role in the life of patients with rheumatic disorders, in all the domains of the ICF: body functions and structure, activities (action by an individual) and participation (involvement in a life situation). Health professionals in rheumatology can make the difference in the lives of RA patients and their families.

    Rheumatoid arthritis (RA) is a long-lasting intractable autoimmune disorder, which has become a substantial public health problem. Despite widespread use of biologic drugs, there have been uncertainties in efficacy and long-term safety. Mesenchymal stem cells (MSCs) have been suggested as a promising alternative for the treatment of RA because of their immunomodulatory properties. However, the precise mechanisms of MSCs on RA-related immune cells are not fully elucidated. The aim of this study was to investigate the therapeutic potential of human umbilical cord blood-derived MSCs (hUCB-MSCs) as a new therapeutic strategy for patients with RA and to explore the mechanisms underlying hUCB-MSC-mediated immunomodulation. Mice with collagen-induced arthritis (CIA) were administered with hUCB-MSCs after the onset of disease, and therapeutic efficacy was assessed. Systemic delivery of hUCB-MSCs significantly ameliorated the severity of CIA to a similar extent observed in the etanercept-treated group. hUCB-MSCs exerted this therapeutic effect by regulating macrophage function. To verify the regulatory effects of hUCB-MSCs on macrophages, macrophages were co-cultured with hUCB-MSCs. The tumor necrosis factor (TNF)-α-mediated activation of cyclooxygenase-2 and TNF-stimulated gene/protein 6 in hUCB-MSCs polarized naive macrophages toward an M2 phenotype. In addition, hUCB-MSCs down-regulated the activation of nucleotide-binding domain and leucine-rich repeat pyrin 3 inflammasome via a paracrine loop of interleukin-1β signaling. These immune-balancing effects of hUCB-MSCs were reproducible in co-culture experiments using peripheral blood mononuclear cells from patients with active RA. hUCB-MSCs can simultaneously regulate multiple cytokine pathways in response to pro-inflammatory cytokines elevated in RA microenvironment, suggesting that treatment with hUCB-MSCs could be an attractive candidate for patients with treatment-refractory RA.

    The aims of the current study are to describe gadolinium-enhanced MRI features of an acute flare of established gouty arthritis in different joints and to examine a possible association between serum uric acid and MRI signs indicative of ongoing inflammation and/or structural joint damage as well as association with disease characteristics and laboratory findings. Twenty-seven male patients with established chronic gout agreed to participate, mean age 47.6 years, and mean disease duration in months 43.2 (±31.8). For all patients, detailed demographic, disease characteristics, and laboratory findings were obtained and correlated with MRI findings. In 27 patients with established gout, a total of 50 MRI studies were performed of the following joints: feet joints (n = 23), ankles (n = 18), knees (n = 5), and hand and wrist joints (n = 4). MRI revealed capsular thickening in 19 patients, bone marrow edema (BME) in 15, soft tissue edema (STE) in 20, joint effusion in 21, bone erosions in 17, cartilaginous erosions in 4, and tenosynovitis in 9 cases. In 17 cases, tophaceous lesions were found. Post contrast MRI showed synovial thickening in seven cases. Positive correlations were observed between serum uric acid levels and the following MRI findings: capsular thickening (r = 0.552, p = 0.003), BME (r = 0.668, p ≤ 0.0001), STE (r = 0.559, p = 0.002), and tenosynovitis (r = 0.513, p = 0.006). Using MRI in chronic gout, important features can be detected like BME, minute cartilaginous erosions, and hypertrophic synovial inflammation in post contrast MR images. Serum uric acid (SUA) was positively correlated with capsular thickening, BME, STE, and tenosynovitis.

  13. Increased Risk of Chronic Kidney Disease in Rheumatoid Arthritis Associated with Cardiovascular Complications - A National Population-Based Cohort Study.

    Hsien-Yi Chiu

    Full Text Available There have been few large population-based studies of the association between rheumatoid arthritis (RA and chronic kidney disease (CKD and glomerulonephritis. This nationwide cohort study investigated the risks of developing CKD and glomerulonephritis in patients with RA, and the associated risks for cardiovascular complications.From the Taiwan National Health Insurance Research Database, we identified a study cohort of 12,579 patients with RA and randomly selected 37,737 subjects without RA as a control cohort. Each subject was individually followed for up for 5 years, and the risk of CKD was analyzed using Cox proportional hazards regression models.During the follow-up period, after adjusting for traditional cardiovascular risk factors RA was independently associated with a significantly increased risk of CKD (adjusted hazard ratio [aHR] 1.31; 95% confidence interval [CI] 1.23-1.40 and glomerulonephritis (aHR 1.55; 95% CI 1.37-1.76. Increased risk of CKD was also associated with the use of non-steroidal anti-inflammatory drugs, cyclosporine, glucocorticoids, mycophenolate mofetil, and cyclophosphamide. Patients with comorbidities had even greater increased risk of CKD. Moreover, RA patients with concurrent CKD had significantly higher likelihood of developing ischemic heart disease and stroke.RA patients had higher risk of developing CKD and glomerulonephritis, independent of traditional cardiovascular risk factors. Their increased risk of CKD may be attributed to glomerulonephritis, chronic inflammation, comorbidities, and renal toxicity of antirheumatic drugs. Careful monitoring of renal function in RA patients and tight control of their comorbid diseases and cardiovascular risk factors are warranted.

    Rheumatoid arthritis is a chronic inflammatory joint disease, which can cause cartilage and bone damage as well as disability. Early diagnosis is key to optimal therapeutic success, particularly in patients with well-characterised risk factors for poor outcomes such as high disease activity, presence of autoantibodies, and early joint damage. Treatment algorithms involve measuring disease activity with composite indices, applying a treatment-to-target strategy, and use of conventional, biological, and newz non-biological disease-modifying antirheumatic drugs. After the treatment target of stringent remission (or at least low disease activity) is maintained, dose reduction should be attempted. Although the prospects for most patients are now favourable, many still do not respond to current therapies. Accordingly, new therapies are urgently required. In this Seminar, we describe current insights into genetics and aetiology, pathophysiology, epidemiology, assessment, therapeutic agents, and treatment strategies together with unmet needs of patients with rheumatoid arthritis.

    Hemodynamics, external respiratory function (ERF), blood gas composition and viscosity were studied in 120 patients with chronic obstructive bronchitis at different developmental stage of cor pulmonale. In pulmonary hypertension, there were moderate ERF disorders that became more marked in the compensatory and particularly decompensatory cor pulmonale. As bronchial patency deteriorated, the index of right ventricular performance increased from 0.76+0.081 to 1.23+0.022 in the examinees. Examination of blood gas composition revealed insignificant hypoxemia in pulmonary hypertension and compensatory cor pulmonale, which progressed with decompensation of chronic cor pulmonale (CCP). As bronchial obstruction progressed, there were increases in systolic, diastolic, and mean pressure in the pulmonary artery. The viscosity of blood and plasma and the indices of red blood cell aggregation and deformability were in the normal range in pulmonary hypertension and compensatory CCP. In CCP decompensation, the viscosity of blood and plasma and the index of red blood cell aggregation were increased and the index of red blood cell deformability was decreased.

    Full Text Available Louise SharpeSchool of Psychology, The University of Sydney, Sydney, NSW, AustraliaAbstract: There are numerous reviews and meta-analyses that confirm that psychological therapy is efficacious for patients with rheumatoid arthritis (RA in terms of managing pain. Therefore, the literature has moved on to answer additional questions: 1 What types of interventions are most strongly supported by the current evidence? 2 Do different patients benefit from different approaches? 3 When is it best to intervene? 4 What modalities are best for administering the intervention? 5 What model of care should we be proposing that will result in widespread implementation and will ensure access for patients with RA? This review concludes that cognitive behavioral therapy (CBT is the most efficacious treatment for pain management in RA; however, there are indications that mindfulness may have particular benefits for patients with a history of depression. CBT is most effective when administered early in the course of the disease. However, there is at present little evidence to confirm whether or not psychosocial interventions are effective for patients with comorbid psychological disorders. One of the major challenges is ensuring access to effective interventions for patients, particularly early on in the course of the disease, with a view to preventing physical and psychological morbidity. A stepped-care model is proposed; however, we urgently need more, better-quality trials of minimal interventions, particularly in Internet-delivered CBT, which appears promising and may form the cornerstone of future stepped-care models for providing psychosocial care to patients with RA.Keywords: pain, pain management, cognitive behavioral therapy, psychosocial treatment, coping, psychosocial, psychotherapy

    Introduction Direct detection of microbial super antigens in synovial fluid of patients with rheumatoid arthritis may be able to guide to the design of cost-effective therapies. The purpose of this study was to assess the existence of Staphylococcal enterotoxin A (superantigen A) in the synovial fluid of patients with RA by the PCR and ELISA methods. Methods This experimental study was conducted on the synovial fluid of 103 RA patients from Baqiyatallah University of Medical Sciences’ Rheumatology Clinic in Tehran, Iran in 2011–2014. Bacterial cultures, polymerase chain reaction with specific primer pairs and enzyme-linked immunosorbent assay (ELISA) methods were used. The PCR products were subjected to sequence as a confirmatory molecular method results. The data were descriptively analyzed by SPSS Version 19. Results The bacteriological study result indicated that, in four cases (3.8%) of the patients, bacterial strains were isolated. The result of PCR molecular method for staphylococcal enterotoxin A gene showed that, 42 of the patients (40.7%) tested positive for the ent A gene. The results of ELISA were positive for staphylococcal enterotoxin A (superantigen A) in 51 cases (49.51%) of the patients’ synovial fluids. The results indicated that the possibility of detecting superantigen A in the SF of RA patients, but the origin of the enterotoxin A gene remained unknown. Conclusions The findings of this study may be able to alter the actual theory on the pathogenesis, diagnosis, and treatment of RA patients. In addition, the results have shown the probability of an endogenous origin for the involved superantigen A in RA patients’ synovial fluids. PMID:27053990

    Full Text Available This single-blind, placebo-controlled study assesses the efficacy of synergic administration of intravenous laser blood irradiation (ILBI and etanercept in selected subtypes of juvenile idiopathic arthritis (JIA. Etanercept is a tumor necrosis factor alpha blocking agent with recognized importance in JIA. Laser radiation has immunomodulatory effects in animal and human studies. Fourteen patients (Group I received ILBI and 9 patients (Group II received placebo laser. ILBI was performed in addition to ongoing JIA medication, including etanercept. ILBI was administrated in 3 sets of 5 consecutive daily sessions, with a 7-week interval between every set of sessions. Evaluation was performed using ACR (American College of Rheumatology Pediatric Criteria (ACR Pedi at study enrollment and at 10 and 20 weeks, respectively. After 10 weeks, 85.7% of the patients in Group I fulfilled Pedi 30 criteria, compared to only 55.6% of the patients in Group II. After 20 weeks, all patients in both groups had a Pedi 30 response. In Group I, 92.8% of the subjects met the Pedi 50 response, compared to only 55.6% in the placebo group. One patient in Group I responded best, fulfilling Pedi 70 criteria. If applied synergistically, ILBI and etanercept would have an increased efficacy in promoting JIA remission.

    Full Text Available OBJECTIVE: We evaluated the incidence of and the main risk factors associated with cutaneous adverse events in patients with chronic inflammatory arthritis following anti-TNF-α therapy. METHODS: A total of 257 patients with active arthritis who were taking TNF-α blockers, including 158 patients with rheumatoid arthritis, 87 with ankylosing spondylitis and 12 with psoriatic arthritis, were enrolled in a 5-year prospective analysis. Patients with overlapping or other rheumatic diseases were excluded. Anthropometric, socioeconomic, demographic and clinical data were evaluated, including the Disease Activity Score-28, Bath Ankylosing Spondylitis Disease Activity Index and Psoriasis Area Severity Index. Skin conditions were evaluated by two dermatology experts, and in doubtful cases, skin lesion biopsies were performed. Associations between adverse cutaneous events and clinical, demographic and epidemiological variables were determined using the chi-square test, and logistic regression analyses were performed to identify risk factors. The significance level was set at p<0.05. RESULTS: After 60 months of follow-up, 71 adverse events (73.85/1000 patient-years were observed, of which allergic and immune-mediated phenomena were the most frequent events, followed by infectious conditions involving bacterial (47.1%, parasitic (23.5%, fungal (20.6% and viral (8.8% agents. CONCLUSION: The skin is significantly affected by adverse reactions resulting from the use of TNF-α blockers, and the main risk factors for cutaneous events were advanced age, female sex, a diagnosis of rheumatoid arthritis, disease activity and the use of infliximab.

    The present study investigated the pharmacological effect of agmatine in Complete Freud Adjuvant (CFA) induced arthritis and cachexia in rats. The rats were injected with CFA (0.1ml/rat) to induced symptoms of arthritis. Day 8 onwards of CFA administration, rats were injected daily with agmatine for next 7days, and arthritis score, body weights and food intake were monitored daily (g). Since cachexia is known to produce severe inflammation, malnutrition and inhibition of albumin gene expression, we have also monitored the total proteins, albumin, TNF-α and IL-6 levels in arthritic rats and its modulation by agmatine. In the present study, CFA treated rats showed a progressive reduction in both food intake and body weight. In addition analysis of blood serum of arthritis animals showed a significant reduction in proteins and albumin and significant elevation in tumor necrosis factor (TNF)-α and Interleukins (IL)-6. Chronic agmatine (20-40mg/kg, ip) treatment not only attenuated the signs of arthritis but also reverses anorexia and body weight loss in CFA treated rats. In addition, agmatine restored total protein and albumin and reduces TNF-α and IL-6 levels in arthritis rats. These results suggest that agmatine administration can prevent the body weights loss and symptoms of arthritis via inhibition of inflammatory cytokines.

    Recently, a noninvasive and highly proliferative stem cell population from menstrual blood called MenSCs has been identified. Despite their use in clinical studies, their immunomodulatory properties have not yet been investigated. In this context, we studied the immunosuppressive properties of MenSCs in comparison with the well-characterized bone marrow derived-MSCs (BM-MSCs). Using an in vitro proliferation assays, we showed that MenSCs displayed a lower suppressive effect on peripheral blood mononuclear cells and in particular on the proinflammatory CD4(+) IFN-γ(+) and CD8(+) IFNγ(+) cells than BM-MSCs. Moreover, compared to BM-MSCs, MenSCs activated with IFN-γ and IL-1β produced lower amounts of immunosuppressive factors such as IDO, PDL-1, PGE2, and Activin A and exhibited a substantial lower expression level of IFN-γ receptor subunits. In the collagen induced arthritis model, while BM-MSCs administration resulted in a potent therapeutic effect associated with a significant decrease of proinflammatory T cell frequency in the lymph nodes, MenSCs injection did not. In contrast, in the xeno-GVHD model, only MenSCs administration significantly increased the survival of mice. This beneficial effect mediated by MenSCs was associated with a higher capacity to migrate into the intestine and liver and not to their anti-inflammatory capacities. All together our results demonstrate for the first time that the therapeutic potential of MSC in the experimental xeno-GVHD model is independent of their immunosuppressive properties. These findings should be taken into consideration for the development of safe and effective cell therapies.

    2016-01-01

    Rheumatoid arthritis is a common chronic inflammatory and destructive arthropathy that consumes considerable personal, social and economic costs. It consists of a syndrome of pain, stiffness and symmetrical inflammation of the synovial membrane (synovitis) of freely moveable joints such as the knee (diarthrodial joints). Although the etiology of rheumatoid arthritis is unclear, the disease is characterized by inflammation of the synovial lining of diarthrodial joints, high synovial proliferation and an influx of inflammatory cells, macrophages and lymphocytes through angiogenic blood vessels. Diseasemodifying antirheumatic drugs slow disease progression and can induce disease remission in some patients. Methotrexate is the first line therapy, but if patients become intolerant to this drug, biologic agents should be used. The development of biological substances for the treatment of rheumatic conditions has been accompanied by ongoing health economic discussions regarding the implementation of these highly effective, but accordingly, highly priced drugs are the standard treatment guidelines of rheumatic diseases. In this way, more efficient strategies have to be identified. Despite numerous reviews in rheumatoid arthritis in the last years, this area is in constant development and updates are an urgent need to incorporate new advances in rheumatoid arthritis research. This review highlights the immunopathogenesis rationale for the current therapeutic strategies in rheumatoid arthritis.

    The effects of social stress on several blood immune measures and collagen-induced arthritis (CIA) were investigated in Wistar rats using the resident-intruder confrontation paradigm to induce stress of different intensity. Male intruders were exposed for one week to a dominant opponent either repeatedly for 4h daily (moderate stress) or continuously (severe stress). Arthritis was induced by intradermal injection of collagen type II (CII) into the tail skin at the end of day 3 of confrontation. Only severe stress was associated with decreased CD4 and CD8 T cells, and the increase in granulocyte numbers and body mass loss was more pronounced under these conditions. Only severe stress reduced the susceptibility to arthritis by about 50%. Severity scores did not differ in the first five days after disease onset between all groups. Subsequent experiments focused on severely stressed rats indicated that disease progressed until day 10 only in control animals, but not in severely stressed males. Stressor exposure resulted in increased blood monocyte numbers, but these males failed to accumulate macrophages into the skin at the site of CII injection. High numbers of attacks experienced by intruders correlated with delayed disease onset in severely stressed rats. We hypothesize that severe stress persisting after disease induction exhibits beneficial effects on the susceptibility of CIA and propose that the specific endocrine and immunological profile associated with severe stress is an important factor for disease outcome--a factor which probably explains many of the conflicting data of previous stress studies on CIA.

    Full Text Available Many studies in hypertensive humans and animals have shown that increased blood viscosity is in direct relation with essential hypertension. The aim of our studies was to investigate the effects of chronic hematocrit value changes on arterial blood pressure and kidney function in genetically induced hypertension. To this end, we studied the effects of several interventions, designed to increase/decrease hematocrit, on hemodynamic parameters, vascular reactivity, glomerular filtration and renal function curve in spontaneously hypertensive rats (SHR. Results of our study show that chronic hematocrit value elevation increases blood pressure and peripheral vascular resistance in SHR. On the other hand, chronic hematocrit lowering elucidates blood pressure and peripheral vascular resistance decrease followed by cardiac output rising. Both hematocrit value changes significantly reduce vasodilatory vascular response. Hematocrit lowering induces acute renal failure. Sodium excretion is shifted to higher blood pressure values in high hematocrit value animals and opposite - lower blood pressure values in low hematocrit value animals. Repeated transfusions develop salt sensitive malignant hypertension in SHR. Further studies are necessary to evaluate the degree of kidney damage after chronic hematocrit value changes in SHR.

    Full Text Available Hypertension, diabetes, and proteinuria are well-recognized risk factors for progressive kidney function loss. However, despite excellent antihypertensive and antidiabetic drug therapies, which also often lower urinary protein excretion, there remains a significant reservoir of patients with chronic kidney disease who are at high risk for progression to end-stage kidney disease. This has led to the search for less traditional cardiovascular risk factors that will help stratify patients at risk for more rapid kidney disease progression. Among these are noninvasive estimates of vascular structure and function. Arterial stiffness, manifested by the pulse wave velocity in the aorta, has been established in a number of studies as a significant risk factor for kidney disease progression and cardiovascular endpoints. Much less well studied in chronic kidney disease are measures of central arterial pressures. In this paper we cover the physiology behind the generation of the central pulse wave contour and the studies available using these approaches and conclude with some speculations on the rationale for why measurements of central pressure may be informative for the study of chronic kidney disease progression.

    Several studies point to the increased risk of reactivation of latent tuberculosis infection (LTBI) in patients with chronic inflammatory arthritis (CIAs) after using tumour necrosis factor (TNF)α blockers. To study the incidence of active mycobacterial infections (aMI) in patients starting TNF α blockers, 262 patients were included in this study: 109 with rheumatoid arthritis (RA), 93 with ankylosing spondylitis (AS), 44 with juvenile idiopathic arthritis (JIA) and 16 with psoriatic arthritis (PsA). All patients had indication for anti-TNF α therapy. Epidemiologic and clinical data were evaluated and a simple X-ray and tuberculin skin test (TST) were performed. The control group included 215 healthy individuals. The follow-up was 48 months to identify cases of aMI. TST positivity was higher in patients with AS (37.6%) than in RA (12.8%), PsA (18.8%) and JIA (6.8%) (p < 0.001). In the control group, TST positivity was 32.7%. Nine (3.43%) patients were diagnosed with aMI. The overall incidence rate of aMI was 86.93/100,000 person-years [95% confidence interval (CI) 23.6-217.9] for patients and 35.79/100,000 person-years (95% CI 12.4-69.6) for control group (p < 0.001). All patients who developed aMI had no evidence of LTBI at the baseline evaluation. Patients with CIA starting TNF α blockers and no evidence of LTBI at baseline, particularly with nonreactive TST, may have higher risk of aMI. PMID:26560983

  4. Limitations of clinical trials in chronic diseases: is the efficacy of methotrexate (MTX) underestimated in polyarticular psoriatic arthritis on the basis of limitations of clinical trials more than on limitations of MTX, as was seen in rheumatoid arthritis?

    Clinical trials are the optimal method to establish efficacy of a drug versus placebo or another drug. Nonetheless, important limitations are seen, particularly in chronic diseases over long periods, although most are ignored. Pragmatic limitations of clinical trials include a relatively short observation period, suboptimal dosage schedules, suboptimal surrogate markers for long-term outcomes, statistically significant results which may not be clinically unimportant and vice versa. Even ideal clinical trials have intrinsic limitations, including the influence of design on results, data reported in groups which ignore individual variation, non-standard observer-dependent interpretation of a balance of efficacy and toxicity, and distortion of a "placebo effect." Limitations are seen in many clinical trials of methotrexate (MTX) in rheumatoid arthritis (RA) and psoriatic arthritis (PsA). The first MTX clinical trial in rheumatology documented excellent efficacy in PsA, but frequent adverse events in 1964, explained by intravenous doses up to 150 kg. MTX was abandoned until the 1980s for RA, while gold salts and penicillamine were termed "remission-inducing," on the basis limitations of clinical trials. In the most recent MTX in PsA (MIPA) trial, all outcomes favoured MTX, but only patient and physician global estimates met the pclinical trials than from limitations of MTX.

    Full Text Available Abstract Background Rheumatoid arthritis (RA is a chronic autoimmune disease, which causes synovial damage. Persistence of lymphocyte infiltrates in the rheumatoid synovium has been attributed to abnormal apoptosis. While not comprehensively investigated, perturbations in peripheral blood lymphocyte (PBL apoptosis may also be involved in perpetuation of autoimmune processes in RA. Methods We investigated total, CD4+ and CD19+ PBL apoptosis in our study cohort by monitoring the translocation of phosphatidylserine using the Annexin-V assay. To examine the role of death receptor mediated apoptosis as well as activation-induced-cell-death (AICD, PBLs were labeled with CD95/Fas and CD69 markers and enumerated by flow cytometry. Proteolytic activity of initiator and executioner caspases was determined by luminometry. DNA fragmentation assays were used to examine whether apoptotic signals were transduced to the nucleus. Quantitative PCR arrays were used to investigate apoptotic pathways associated with RA-PBLs. Since heat-shock-protein-70 (HSP70 is an inducible protein which modulates apoptotic signals, we determined HSP70 levels by intra-cellular flow cytometry and western blots. Results The RA-PBLs showed signs of elevated apoptosis whilst in circulation. These include increases in the loss of plasma membrane asymmetry, indicated by increased externalization of phosphatidylserine (especially in B-lymphocytes. RA-PBLs showed a bias to CD95/Fas mediated apoptotic pathways, but low levels of the CD69 marker suggested that this was not associated with immune activation. Although downstream markers of apoptosis such as caspase-3/7 activity, were increased, no DNA fragmentation was observed in RA-PBLs. Interestingly, elevated levels of apoptosis did not correlate with absolute lymphocyte counts in RA patients. Levels of HSP70 were highly elevated in RA-PBLs compared to controls. Conclusion The results suggest that while apoptosis may be initiated in RA

    Rheumatoid arthritis (RA) is a chronic inflammatory disease characterized by the destruction of articular cartilage and bone with elevated levels of proinflammatory cytokines. It has been reported that IL-17 and Th17 cells play important roles in the pathogenesis of RA. Recently, plasticity in helper T cells has been demonstrated; Th17 cells can convert to Th1 cells. It remains to be elucidated whether this conversion occurs in the early phase of RA. Here, we tried to identify Th17 cells, Th1 cells, and Th17 cell-derived Th1 cells (CD161(+)Th1 cells) in the peripheral blood of early-onset RA patients. We also evaluated the effect of methotrexate on the ratio of Th17 cells in early-onset RA patients. The ratio of Th17 cell-derived Th1 cells to CD161(+)Th17 cells was elevated in the peripheral blood of early-onset RA patients. In addition, MTX reduced the ratio of Th17 cells but not Th1 cells. These findings suggest that IL-17 and Th17 play important roles in the early phase of RA; thus, anti-IL-17 antibodies should be administered to patients with RA in the early phase.

    Objective:To observe the clinical effect of Rebixiao granule (热痹消颗粒剂, RBXG) in treating repeatedly attacking acute gouty arthritis and through experimental study on blood uric acid to explore RBXG's therapeutic mechanism. Methods: Ninety repeatedly attacking acute gouty arthritis patients were divided into the treated group (n= 60) and control group (n = 30). The treated group was treated with RBXG, and the control group was treated with Futalin tablets (diclofenac sodium). The baseline treatment including good rest, Iow purine diet, sufficient water drinking and urine alkalization, etc. was then given to both groups. Hypoxanthine 600 mg/kg and niacin 100 mg/kg was applied to hyperuricemic mice by gastrogavage to establish the animal models. Results: The clinical effective rate of the treated group was 95.0% and that of the control 90.0 %. Good therapeutic effects were won, insignificant difference (P>0.05)was shown between the two groups. However, the cure rate of the treated group was 26.7% while that of the control group was 10.0%, with significant difference (P<0.01) shown between them. The treated group had its blood uric acid lowered, which was significantly different (P<0.05) from that of the control group. The animal experiment indicated that all the three groups treated with different dosages of RBXG, as well as the Ash bark and Smilax glabra rhizome groups had their blood uric acid content reduced in the hyperuricemic mice. Conclusion: RBXG has a quicker initiation and better treatment effects than sole anti-inflammatory and analgesic agents on the treatment of repeatedly attacking acute gouty arthritis, showing no obvious toxic or adverse reactions and therefore good for long-term administration and likely to be a safe TCM preparation to control the symptoms and reduce the onsets of repeatedly attacking of acute gouty arthritis. The animal experiment shows that both the compound preparation and part of the single ingredients in the

    Full Text Available In the present study we examined gross changes in the mass of whole adrenal glands and that of the adrenal cortex, as well as the serum corticosterone and glucose level of mature male Wistar rats subjected to three different treatments: animals subjected to chronic restraint-stress, animals injected with lithium (Li and chronically stressed rats treated with Li. Under all three conditions we observed hypertrophy of whole adrenals, as well as the adrenal cortices. Chronic restraint stress, solely or in combination with Li treatment, significantly elevated the corticosterone level, but did not change the blood glucose level. Animals treated only with Li exhibited an elevated serum corticosterone level and blood glucose level. The aim of our study was to investigate the modulation of the chronic stress-induced effect on the blood glucose level by lithium, as a possible mechanism of avoiding the damage caused by chronic stress. Our results showed that lithium is an agent of choice which may help to reduce stress-elevated corticosterone and replenish exhausted glucose storages in an organism.

    The authors previously reported that the visit-to-visit variability of blood pressure is correlated with renal function decline in nondiabetic chronic kidney disease. Little is known about the association between visit-to-visit variability and renal function decline in patients with diabetic chronic kidney disease. The authors retrospectively studied 69 patients with diabetic chronic kidney disease stage 3a, 3b, or 4. The standard deviation and coefficient of variation of blood pressure in 12 consecutive visits were defined as visit-to-visit variability of blood pressure. The median observation period was 32 months. In univariate correlation, the standard deviation and coefficient of variation of blood pressure were not significantly associated with the slope of estimated glomerular filtration rate. There was no significant association between the visit-to-visit variability of blood pressure and renal function decline in patients with diabetic chronic kidney disease, in contrast with our previous study of nondiabetic patients with chronic kidney disease.

    As the semiautomated electrophoretic analysis of proteinuria still needs technical experience, interest was focused on easy-to-perform methods of urinary protein measurement. SRID-tests for albumin, transferrin, IgG, alpha-1-microglobulin and a spectrophotometrical test for beta-NAG were carried out in 50 normal controls and compared to PCI/ECI-values of patients suffering from rheumatoid arthritis (n = 52) and various types of chronic glomerulonephritis (n = 41). Elevated levels of alpha-1-M and beta-NAG in chronic glomerulonephritis were interpreted as indicative for tubulointerstitial involvement in the chronic inflammatory process. PCI/ECI elevation in individual RA-samples may be caused by functional impairment of tubular protein handling due to chronic ingestion of non-steroid analgesics. The serum assays for transferrin (TF) and IgG based on SRID technique turned out to be too insensitive for the application on unconcentrated urine of normal control persons. In renal patients, however, TF-PCI values above 30 mg/g crea and IgG-PCI values above 50 mg/g crea have to be interpreted as pathologic indicating damage of the glomerular basement membrane. To elucidate TF- and IgG-values in urines with low protein content, highly sensitive nephelometric methods should be used. Concentration of urinary proteins using membrane filters may lead to protein losses, resulting in miscalculation of PC-indices.

    Disorders of iron utilization caused by abnormal elevation of hepcidin levels are the main mechanism of anemia of chronic disease. Hepcidin is mainly produced by the liver. Recently it has been found that monocytes are another source of hepcidin. The increased hepcidin in serum and urine of multiple myeloma patients may be one cause of anemia of chronic disease (ACD). However it is unclear whether the peripheral blood monocyte hepcidin is involved in the pathogenesis of anemia of chronic disease. This study was purposed to investigate the role of monocyte hepcidin in multiple myeloma patients with anemia of chronic disease. The clinical data and peripheral venous blood of multiple myeloma patients were collected.Serum concentration of IL-6 and TNF-α was detected by ELISA. Peripheral blood monocytes were isolated by CD14(+) magnetic beads. Hepcidin, IL-6 and TNF-α mRNA of monocytes were detected by real time quantitative PCR. The results showed that the expression level of monocyte hepcidin mRNA in myeloma patients was higher than that in normal controls. In untreated patients, the expression level of monocyte hepcidin mRNA was negatively correlated with hemoglobin, and positively correlated with serum ferritin and IL-6 levels, but unrelated with TNF-α levels.It is concluded that the increased monocyte hepcidin levels in multiple myeloma patients may play an etiologic role in ACD.

    The antigens of the Duffy blood group system (DARC) act as a receptor for the interleukin IL-8. IL-8 plays an important role in the pathogenesis of chronic periodontitis due to its chemotactic properties on neutrophils. The aim of this study was to investigate a possible association of Duffy blood group gene polymorphisms with the -353T>A, -845T>C and -738T>A SNPs of the IL8 gene in chronic periodontitis. One hundred and twenty-four individuals with chronic periodontitis and 187 controls were enrolled. DNA was extracted using the salting-out method. The Duffy genotypes and IL8 gene promoter polymorphisms were investigated by PCR-RFLP. Statistical analyses were conducted using the Chi square test with Yates correction or Fisher's Exact Test, and the possibility of associations were evaluated by odds ratio with a 95% confidence interval. When analyzed separately, for the Duffy blood group system, differences in the genotype and allele frequencies were not observed between all the groups analyzed; and, in nonsmokers, the -845C allele (3.6% vs. 0.4%), -845TC genotype (7.3% vs. 0.7%) and the CTA haplotype (3.6% vs. 0.4%) were positively associated with chronic periodontitis. For the first time to our knowledge, the polymorphisms of erythroid DARC plus IL8 -353T>A SNPs were associated with chronic periodontitis in Brazilian individuals. In Afro-Brazilians patients, the FY*02N.01 with IL8 -353A SNP was associated with protection to chronic periodontitis.

    Citrullination, a post-translational modification of proteins, is increased in inflammatory processes and is known to occur in smokers. It can induce anti-cyclic citrullinated peptide (CCP) antibodies, the most specific serologic marker for rheumatoid arthritis. Thus far, the incidence of autoimmunity in patients with wood-smoke-induced chronic obstructive pulmonary disease (COPD) resulting in anti-CCP production has not been examined. We hypothesise that anti-CCP antibody level in these patients should be higher than that in healthy subjects. A total of 112 non-rheumatoid arthritis patients, including 56 patients with wood-smoke-induced COPD and 56 patients with tobacco-induced COPD, and 56 healthy non-smoker controls were included. The serum anti-CCP antibody levels were measured and compared between the groups and against smoke exposure and clinical characteristics. The mean anti-CCP antibody levels in wood-smoke-induced COPD group were significantly higher than those in tobacco-induced COPD group (p = 0.03) and controls (p = 0.004). Furthermore, 8 (14.2 %) patients with wood-smoke-induced COPD, 4 (7.14 %) with tobacco-induced COPD and 2 (3.57 %) controls exceeded the conventional cut-off of anti-CCP antibody positivity. No relationship was found between the anti-CCP antibody level and age, gender, duration of disease, Pack-years of smoking, and duration of exposure to wood smoke. Moreover, correlations between anti-CCP antibodies and severity of airflow limitation, CAT scores, mMRC scores of dyspnoea, and GOLD staging of COPD severity were not significant. Wood-smoke-induced COPD could significantly increase the anti-CCP antibody level in non-rheumatoid arthritis patients when compared with that in patients with tobacco-induced COPD and healthy controls.

    study was to evaluate short-term blood pressure response to two different plasma levels of enalaprilat. METHODS: As part of an open, randomized, controlled trial of the effect of high and low dosage of enalapril on the progression of renal failure, short-term blood pressure response was evaluated. Data...... pressures in the two groups were 140 (110-200) and 133 (110-165), in the high and low enalaprilat concentration groups, respectively, and after 3 months they were 135 (105-170) and 130 (105-170) mmHg (NS). Median diastolic blood pressure was 80 mmHg in each group both at baseline (65-100) and at follow......AIMS: In chronic renal failure, the clearance of most ACE inhibitors including enalapril is reduced. Hence, with conventional dosage, plasma enalaprilat may be markedly elevated. It is unclear whether this excess of drug exposure affords an improved control of blood pressure. The aim of the present...

    BACKGROUND: Blood eosinophil counts might predict response to inhaled corticosteroids (ICS) in patients with chronic obstructive pulmonary disease (COPD) and a history of exacerbations. We used data from the WISDOM trial to assess whether patients with COPD with higher blood eosinophil counts would...... to receive either continued or reduced ICS over 12 weeks. We did a post-hoc analysis after complete ICS withdrawal (months 3-12) to compare rate of exacerbations and time to exacerbation outcomes on the basis of blood eosinophil subgroups of increasing cutoff levels. The WISDOM trial is registered...... at ClinicalTrials.gov, number NCT00975195. FINDINGS: In the 2296 patients receiving treatment after ICS withdrawal, moderate or severe exacerbation rate was higher in the ICS-withdrawal group versus the ICS-continuation group in patients with eosinophil counts (out of total white blood cell count) of 2...

    A critical concern in the transmission of prion diseases, including chronic wasting disease (CWD) of cervids, is the potential presence of prions in body fluids. To address this issue directly, we exposed cohorts of CWD-naïve deer to saliva, blood, or urine and feces from CWD-positive deer. We found infectious prions capable of transmitting CWD in saliva (by the oral route) and in blood (by transfusion). The results help to explain the facile transmission of CWD among cervids and prompt caution concerning contact with body fluids in prion infections.

    Objective:To examine metabolic disorders of major components of organic basis of bone tissue in patients with chronic hematogenous osteomyelitis and response to surgical treatment. Methods: The cubital vein puncture was conducted to take blood for analysis in patients with chronic hematogenous osteomyelitis. The activity of collagenase and hyaluronidase, elastin, elastase and total content of glycosaminoglycans were measured in blood serum. Results: The study revealed an enhancement of catabolic phase of metabolism of the main components in bone organic matrix during the relapse of inflammation. It was evidenced by indicators reflecting the synthetic and catabolic phases of the main components of the connective tissue collagen and glycosaminoglycans. The effective therapeutic treatments led to the reduction and normalization of studied compounds. Conclusions: The initial development of hematogenous osteomyelitis happens in a background of metabolic disorders of the main components of organic matrix of bone tissue, and normalizes upon effective therapy.

    In order to discuss the diversity of clinical features and the difficulty in diagnosis of children with juvenile rheumatoid arthritis (JRA), we present two cases who have documented the development of systemic lupus erythematosus (SLE) and mixed connective tissue disease (MCTD) after a long period of disease characterized only by arthritis that was initially diagnosed as JRA. The first case was a girl diagnosed for her arthritic joints as polyarticular JRA at 15 years of age. At onset, she had Raynaud phenomenon but autoantibodies such as anti-nuclear antibody (ANA), anti-DNA antibody, and rheumatoid factor were negative. Five years after onset, she became ANA positive and 3 years later she became pregnant. During her pregnancy, she became positive for anti-DNA antibody without any signs of nephritis. One month after the delivery, however, she developed butterfly rash, carditis, nephritis, and was diagnosed as SLE. No destructive changes were observed in her joints though arthritis continued for 8 years form onset to pregnancy. The second case was a 3 years old girl who was diagnosed as polyarticular JRA. Treatment by aspirin induced complate remission after one year from the onset. However, 10 years after that remission, she developed Raynaud phenomenon and arthralgia in her knees and hip joints. Her laboratory findings showed hypergammaglobulinemia, positive ANA, positive anti-DNA antibody, positive anti-RNP antibody. She was eventually diagnosed as MCTD when she was found to have polymyositis by EMG and serum CK. In the present paper, two cases imply the difficulty in diagnosing JRA and diversity of rheumatic diseases such as JRA, SLE and MCTD. Closer and longer period of observation is essential for the JRA patients with nondestructive arthritis.

    In order for acute gouty arthritis to occur, neutrophils must interact with monosodium urate (MSU) crystals. As a result of this interaction, enzymes, chemotactic factors, and other mediators of the inflammatory response are released from neutrophil lysosomes. It was observed that MSU crystals adsorb gamma globulin, albumin, and other proteins found in serum and joint fluid. Results are reported from a study designed to demonstrate the effects of coating of MSU crystals with proteins on the phlogistic responses of neutrophils to crystals.

    The in vivo angiogenic potential of transplanted human umbilical cord blood (UCB) CD133(+) stem cells in experimental chronic hepatic fibrosis induced by murine schistosomiasis was studied. Enriched cord blood-derived CD133(+) cells were cultured in primary medium for 3 weeks. Twenty-two weeks post-Schistosomiasis infection in mice, after reaching the chronic hepatic fibrotic stage, transplantation of stem cells was performed and mice were sacrificed 3 weeks later. Histopathology and electron microscopy showed an increase in newly formed blood vessels and a decrease in the fibrosis known for this stage of the disease. By immunohistochemical analysis the newly formed blood vessels showed positive expression of the human-specific angiogenic markers CD31, CD34 and von Willebrand factor. Few hepatocyte-like polygonal cells showed positive expression of human vascular endothelial growth factor and inducible nitric oxide synthase. The transplanted CD133(+) human stem cells primarily enhanced hepatic angiogenesis and neovascularization and contributed to repair in a paracrine manner by creating a permissive environment that enabled proliferation and survival of damaged cells rather than by direct differentiation to hepatocytes. A dual advantage of CD133(+) cell therapy in hepatic disease is suggested based on its capability of hematopoietic and endothelial differentiation.

    2007-09-01

    Thirty-nine samples of synovial fluid were collected from the joints of 32 horses with suspected septic arthritis and 39 samples were collected from horses euthanased for non-orthopaedic conditions. The white blood cell counts (WBCC) were determined and the pro and active forms of matrix metalloproteinases (MMPs) 2 and 9 were measured by gelatin zymography and image analysis in each sample. The initial measurements of the ratio of proMMP9:proMMp2 and WBCC were good prognostic indicators of the survival of the horses. There was no significant relationship between the interval between the injury and the horse being referred for treatment and either the WBCC or the levels of MMP2 and MMP9 initially, and no evidence that this interval significantly affected the chances of the horses surviving.

    Full Text Available Abstract Background Payments for red blood cell (RBC transfusions are separate from US Medicare bundled payments for dialysis-related services and medications. Our objective was to examine the economic burden for payers when chronic dialysis patients receive outpatient RBC transfusions. Methods Using Truven Health MarketScan® data (1/1/02-10/31/10 in this retrospective micro-costing economic analysis, we analyzed data from chronic dialysis patients who underwent at least 1 outpatient RBC transfusion who had at least 6 months of continuous enrollment prior to initial dialysis claim and at least 30 days post-transfusion follow-up. A conceptual model of transfusion-associated resource use based on current literature was employed to estimate outpatient RBC transfusion payments. Total payments per RBC transfusion episode included screening/monitoring (within 3 days, blood acquisition/administration (within 2 days, and associated complications (within 3 days for acute events; up to 45 days for chronic events. Results A total of 3283 patient transfusion episodes were included; 56.4% were men and 40.9% had Medicare supplemental insurance. Mean (standard deviation [SD] age was 60.9 (15.0 years, and mean Charlson comorbidity index was 4.3 (2.5. During a mean (SD follow-up of 495 (474 days, patients had a mean of 2.2 (3.8 outpatient RBC transfusion episodes. Mean/median (SD total payment per RBC transfusion episode was $854/$427 ($2,060 with 72.1% attributable to blood acquisition and administration payments. Complication payments ranged from mean (SD $213 ($168 for delayed hemolytic transfusion reaction to $19,466 ($15,424 for congestive heart failure. Conclusions Payments for outpatient RBC transfusion episodes were driven by blood acquisition and administration payments. While infrequent, transfusion complications increased payments substantially when they occurred.

    Full Text Available INTRODUCTION: Rheumatoid arthritis is a chronic systemic inflammatory disorder that affects many tissue organs such as skin, blood vessels, heart, lungs and muscles but principally affects joints producing synovitis that often progress to tissue destruction of articular cartilage and ankylosis of joints. Pulmonary manifestations in rheumatoid arthritis are varied as the pleura, lung, parenchyma, airways and pulmonary vasculature all can be involved. AIM AND OBJECTIVES : To study the incidence of pleuropulmonary manifestations of Rheumatoid Arthritis in patients who were confirmed to have rheumatoid arthritis by 2010 ACR criteria . 6 METHODOLOGY : This prospective study was carried out at King George Hospital, Visakhapatnam, Andhra Pradesh. It is a Tertiary Care Hospital. The study was conducted from January 2013 to December 2014. RESULTS: A total of sixty patients who were confirmed to have rheumatoid arthritis were included in this study. Of these, female patients were 34 (56.66% and males were 26 (43.33%. In this study, out of sixty patients of rheumatoid arthritis 24 patients (40% had pleuropulmonary manifestations. CONCLUSION : Rheumatoid Arthritis is prevalent in females but pleuropulmonary manifestations are common in males. Prevalence of pleuropulmonary manifestations is independent of duration of rheumatoid arthritis. But presence of pleuropulmonary manifestations indicate the severity of disease process

    Defective regulation of apoptosis may play a role in the development of autoimmune diseases. Fas and Bcl-2 proteins are involved in the control of apoptosis. The aims of this study were to determine the expression of Fas antigen and Bcl-2 protein on peripheral blood T and B lymphocytes from patients with juvenile-onset systemic lupus erythematosus (JSLE), juvenile rheumatoid arthritis (JRA) and juvenile dermatomyositis (JDM). Thirty-eight patients with JSLE, 19 patients with JRA, 10 patients with JDM and 25 healthy controls entered the study. Freshly isolated peripheral blood mononuclear cells (PBMC) were stained for lymphocyte markers CD3, CD4, CD8, CD19 and for Fas and Bcl-2 molecules. Expressions were measured by three-color flow cytometry. Statistical analysis was performed using Kruskal-Wallis test. Percentages of freshly isolated T lymphocytes positively stained for Fas protein from JSLE patients were significantly increased compared to healthy controls, patients with JRA and patients with JDM. Percentages of B lymphocytes positive for Fas from JSLE patients were higher than healthy controls and JRA patients. In addition, Fas expression on T cells from patients with JRA was increased compared to JDM patients. Otherwise, Fas expression on T and B cells from JRA and JDM patients were similar to healthy controls. MFI of Bcl-2 positive T lymphocytes from JSLE patients were significantly increased compared to healthy controls and JRA patients. MFI of Bcl-2 protein on B lymphocytes from JSLE patients was similar to healthy controls and patients with JRA and JDM. Bcl-2 expression did not differ between JRA and JDM patients and healthy controls. In conclusion, increased expression of Fas and Bcl-2 proteins observed in circulating T and B lymphocytes from patients with JSLE, but not from patients with JRA and JDM, suggests that abnormalities of apoptosis may be related to the pathogenesis of JSLE and probably are not a result of chronic inflammation.

    Vascular dementia is a devastating disorder not only for the patient, but also for the family because this neurocognitive disorder breaks the patient's independence, and leads to family care of the patient with a high cost for the family. This complex disorder alters memory, learning, judgment, emotional control and social behavior and affects 4% of the elderly world population. The high blood pressure or arterial hypertension is a major risk factor for cerebrovascular disease, which in most cases leads to vascular dementia. Interestingly, this neurocognitive disorder starts after long lasting hypertension, which is associated with reduced cerebral blood flow or hypoperfusion, and complete or incomplete ischemia with cortical thickness. Animal models have been generated to elucidate the pathophysiology of this disorder. It is known that dendritic complexity determines the receptive synaptic contacts, and the loss of dendritic spine and arbor stability are strongly associated with dementia in humans. This review evaluates relevant data of human and animal models that have investigated the link between long-lasting arterial hypertension and neural morphological changes in the context of vascular dementia. We examined the effect of chronic arterial hypertension and aged in vascular dementia.

    Full Text Available Background: The conventional cytogenetic approach to demonstrate Philadelphia (Ph chromosome at times does not yield enough number of metaphases or are of suboptimal quality. Further, the rapid molecular tests have completely pushed this simple technique into disrepute. Aims: This study aimed to evaluate usefulness of phytohemagglutinin (PHA-stimulated peripheral blood culture for detection of Ph chromosome in chronic myeloid leukemia (CML patients. Materials and Methods: Fifty-six patients, including 11 newly diagnosed cases of CML and 45 patients of CML on imatinib therapy showing the presence of Ph chromosome in unstimulated samples, were included in the study. Cytogenetic analysis was done on unstimulated samples, i.e. bone marrow aspirate, 24- and 48-h peripheral blood culture, and compared with PHA-stimulated 72-h peripheral blood culture. Results: The preparations from PHA-stimulated peripheral blood culture samples in all 56 patients yielded high number of good-quality metaphases. All the 11 (100% newly diagnosed patients and 39/45 (87% of the patients on imatinib therapy showed the presence of Ph chromosome in PHA-stimulated samples. Addition of PHA-stimulated 72-h peripheral blood culture preparation can be of use for increasing the diagnostic yield in cases of CML with suboptimal results on conventional cytogenetics from bone marrow aspirate sample.

    Full Text Available Rheumatoid arthritis (RA and juvenile idiopathic/rheumatoid arthritis (JIA are chronic, inflammatory, systemic, auto-immune diseases characterized by chronic arthritis leading to progressive joint erosions. The individual functional and social impact of rheumatoid arthritis is of great importance. Disability and joint damage occur rapidly and early in the course of the disease. The remarkably improved outcomes have been achieved initiating biologic therapy with close monitoring of disease progression. Biologic agents are drugs, usually proteins, which can influence chronic immune dysregulation resulting in chronic arthritis. According to the mechanism of action these drugs include: 1 anti-TNF drugs (etanercept, infiximab, adalimumab; 2 IL-1 blocking drugs (anakinra; 3 IL-6 blocking drugs (tocilizumab; 4 agents blocking selective co-stimulation modulation (abatacept; 5 CD 20 blocking drugs (rituximab. Biologics targeting TNF-alpha with methotrexate have revolutionized the treatment of RA, producing significant improvement in clinical, radiographic, and functional outcomes not seen previously. The new concept of rheumatoid arthritis treatment defines early diagnosis, early aggressive therapy with optimal doses of disease modifying antirheumatic drugs (DMARDs and, if no improvement has been achieved during six months, early introduction of biologic drugs. The three-year experience of biologic therapy in Serbia has shown a positive effect on disease outcome.

    Science.gov (United States)

    2017-01-01

    Whether inflammation mediates how reproductive events affect chronic-disease risk is unclear. We studied inflammatory biomarkers in the context of reproductive events using National Health and Nutrition Examination Survey (NHANES) data. From 15,986 eligible women from the 1999–2011 data cycles, we accessed information on reproductive events, blood counts, C-reactive protein (CRP), and total homocysteine (tHCY). We calculated blood-count ratios including: platelet-lymphocyte (PLR), lymphocyte-monocyte (LMR), platelet-monocyte (PMR), and neutrophil-monocyte (NMR). Using sampling weights per NHANES guidelines, means for counts, ratios, or biomarkers by reproductive events were compared using linear regression. We performed trend tests and calculated p-values with partial sum of squares F-tests. Higher PLR and lower LMR were associated with nulliparity. In postmenopausal women, lower PMR was associated with early age at first birth and higher NMR with later age at and shorter interval since last birth. Lower PNR and higher neutrophils and tHCY were associated with early natural menopause. In all women, the neutrophil count correlated positively with CRP; but, in premenopausal women, correlated inversely with tHCY. Reproductive events leave residual signatures on blood counts and inflammatory biomarkers that could underlie their links to chronic disease risk. PMID:28234958

  8. Role of tachykinin 1 and 4 gene-derived neuropeptides and the neurokinin 1 receptor in adjuvant-induced chronic arthritis of the mouse.

    Directory of Open Access Journals (Sweden)

    Eva Borbély

    Full Text Available OBJECTIVE: Substance P, encoded by the Tac1 gene, is involved in neurogenic inflammation and hyperalgesia via neurokinin 1 (NK1 receptor activation. Its non-neuronal counterpart, hemokinin-1, which is derived from the Tac4 gene, is also a potent NK1 agonist. Although hemokinin-1 has been described as a tachykinin of distinct origin and function compared to SP, its role in inflammatory and pain processes has not yet been elucidated in such detail. In this study, we analysed the involvement of tachykinins derived from the Tac1 and Tac4 genes, as well as the NK1 receptor in chronic arthritis of the mouse. METHODS: Complete Freund's Adjuvant was injected intraplantarly and into the tail of Tac1(-/-, Tac4(-/-, Tacr1(-/- (NK1 receptor deficient and Tac1(-/-/Tac4(-/- mice. Paw volume was measured by plethysmometry and mechanosensitivity using dynamic plantar aesthesiometry over a time period of 21 days. Semiquantitative histopathological scoring and ELISA measurement of IL-1β concentrations of the tibiotarsal joints were performed. RESULTS: Mechanical hyperalgesia was significantly reduced from day 11 in Tac4(-/- and Tacr1(-/- animals, while paw swelling was not altered in any strain. Inflammatory histopathological alterations (synovial swelling, leukocyte infiltration, cartilage destruction, bone damage and IL-1β concentration in the joint homogenates were significantly smaller in Tac4(-/- and Tac1(-/-/Tac4(-/- mice. CONCLUSIONS: Hemokinin-1, but not substance P increases inflammation and hyperalgesia in the late phase of adjuvant-induced arthritis. While NK1 receptors mediate its antihyperalgesic actions, the involvement of another receptor in histopathological changes and IL-1β production is suggested.

    AIM: To assess the extent of micronutrient and oxidative stress in blood and to examine their linkages with viral loads in chronic hepatitis C patients.METHODS: Hepatitis C virus (HCV)-RNA levels were quantified in the serum from 37 previously untreated patients with chronic hepatitis C. The plasma and erythrocyte micronutrients (zinc, selenium, copper, and iron) were estimated, and malondialdehyde (MDA)contents were determined as a marker to detect oxidative stress. Antioxidant enzymes, superoxide dismutase (SOD),glutathione peroxidase (GPX) and glutathione reductase (GR) activities in blood were also measured. The control group contained 31 healthy volunteers.RESULTS: The contents of zinc (Zn), and selenium (Se)in plasma and erythrocytes were significantly lower in hepatitis C patients than in the controls. On the contrary,copper (Cu) levels were significantly higher. Furthermore,plasma and erythrocyte MDA levels, and the SOD and GR activities in erythrocytes significantly increased in hepatitis C patients compared to the controls. However, the plasma GPX activity in patients was markedly lower. Plasma Se (r= -0.730, P<0.05), Cu (r = 0.635), and GPX (r = -0.675)demonstrated correlations with HCV-RNA loads. Significant correlation coefficients were also observed between HCV-RNA levels and erythrocyte Zn (r = -0.403), Se (r = -0.544), Cu (r = 0.701) and MDA (r = 0.629) and GR (r = 0.441).CONCLUSION: The levels of Zn, Se, Cu, and oxidative stress (MDA), as well as related anti-oxidative enzymes (GR and GPX) in blood have important impact on the viral factors in chronic hepatitis C. The distribution of these parameters might be significant biomarkers for HCV.

    In front of a patient with arthritis, clinical good-sense tells that the most probable diagnosis are the most prevalent ones. Nevertheless, we have to exclude a multiplicity of other aetiologies, less frequent, but with highest implications in the therapeutic conduct. Infections by Brucella and by Borrelia are rare causes of chronic arthritis, yet are diagnosis to consider, even when the clinical manifestations aren't the most typical, as there still exist endemic areas in Portugal. Here we report two clinical cases about patients with arthritis for more than one year, subject to ineffective exams ant treatments. Only the clinical history could put on evidence clinical-epidemiological data, suggestive of Brucellosis and Lyme Disease, namely the professional contact with infected animals, and the history of probable erythema migrans, that pointed toward the correct diagnosis. So, with directed therapeutic, there was complete resolution of the inflammatory symptoms.

    Adjuvant arthritis (AA) is a condition that involves systemic oxidative stress. Unexpectedly, it was found that sarcoplasmic reticulum Ca(2 +)-ATPase (SERCA) activity was elevated in muscles of rats with AA compared to controls, suggesting possible conformational changes in the enzyme. There was no alteration in the nucleotide binding site but rather in the transmembrane domain according to the tryptophan polar/non-polar fluorescence ratio. Higher relative expression of SERCA, higher content of nitrotyrosine but no increase in phospholipid oxidation in AA SR was found. In vitro treatments of SR with HOCl showed that in AA animals SERCA activity was more susceptible to oxidative stress, but SR phospholipids were more resistant and SERCA could also be activated by phosphatidic acid. It was concluded that increased SERCA activity in AA was due to increased levels of SERCA protein and structural changes to the protein, probably induced by direct and specific oxidation involving reactive nitrogen species.

    Shift work is a risk factor for inflammation, hypertension, and cardiovascular disease. This increased risk cannot be fully explained by classical risk factors. Shift workers' behavioral and environmental cycles are typically misaligned relative to their endogenous circadian system. However, there is little information on the impact of acute circadian misalignment on cardiovascular disease risk in shift workers, independent of differences in work stress, food quality, and other factors that are likely to differ between night and day shifts. Thus, our objectives were to determine the independent effect of circadian misalignment on 24-h high-sensitivity C-reactive protein (hs-CRP; a marker of systemic inflammation) and blood pressure levels-cardiovascular disease risk factors-in chronic shift workers. Chronic shift workers undertook two 3-day laboratory protocols that simulated night work, comprising 12-hour inverted behavioral and environmental cycles (circadian misalignment) or simulated day work (circadian alignment), using a randomized, crossover design. Circadian misalignment increased 24-h hs-CRP by 11% ( p Circadian misalignment increased 24-h systolic blood pressure (SBP) and diastolic blood pressure (DBP) by 1.4 mmHg and 0.8 mmHg, respectively (both p ≤ 0.038). The misalignment-mediated increase in 24-h SBP was primarily explained by an increase in SBP during the wake period (+1.7 mmHg; p = 0.017), whereas the misalignment-mediated increase in 24-h DBP was primarily explained by an increase in DBP during the sleep opportunity (+1.8 mmHg; p = 0.005). Circadian misalignment per se increases hs-CRP and blood pressure in shift workers. This may help explain the increased inflammation, hypertension, and cardiovascular disease risk in shift workers.

    Environmental noise levels in the United States are increasing, yet there are few studies in which the nonauditory effects of workplace noise are assessed. In the current study, the authors examined chronic effects of noise on blood pressure and heart rate in 374 workers at an automobile plant. Data were collected from subjects prior to the start of their workshift. Participants completed questionnaires about diet, alcohol use, lifestyle, noise annoyance, use of hearing protection, noise exposure outside of the work environment, personal and family health histories, and demographic information. Resting blood pressure, heart rate, and body mass index were obtained. Noise exposure levels were extracted retrospectively from company records for each participant for the past 5 yr. Summary statistics were generated for each variable, and the authors performed bivariate correlations to identify any unadjusted associations. The authors then completed statistical modeling to investigate the effects of noise on blood pressure and heart rate, after they controlled for other variables (e.g., gender, race, age). The authors controlled for confounding variables, after which use of hearing protection in high-noise areas was a significant predictor of a decrease in both systolic and diastolic blood pressures. The results suggested that the reduction of noise exposure by means of engineering controls or by consistent use of hearing protection by workers may positively affect health outcomes.

    Full Text Available Reactive arthritis is an acute, sterile, non-suppurative and inflammatory arthropaty which has occured as a result of an infectious processes, mostly after gastrointestinal and genitourinary tract infections. Reiter syndrome is a frequent type of reactive arthritis. Both reactive arthritis and Reiter syndrome belong to the group of seronegative spondyloarthropathies, associated with HLA-B27 positivity and characterized by ongoing inflammation after an infectious episode. The classical triad of Reiter syndrome is defined as arthritis, conjuctivitis and urethritis and is seen only in one third of patients with Reiter syndrome. Recently, seronegative asymmetric arthritis and typical extraarticular involvement are thought to be adequate for the diagnosis. However, there is no established criteria for the diagnosis of reactive arthritis and the number of randomized and controlled studies about the therapy is not enough.

    The reasons for development of chronic inflammation are complex and not fully understood. One of the factors affecting the prolongation of inflammation is changes in cell metabolism, occurring at the center of the inflammatory process. In chronic inflammation there is an imbalance between the processes of storage and consumption of energy reserves. Hypoxia that is a consequence of edema results in transition of white blood cells to anaerobic metabolism. Neutrophils, lymphocytes and macrophages produce active oxygen metabolites which on one hand facilitate the elimination of pathogens, and on the other hand, can cause damage to healthy cells located in the inflamed tissue. In this paper, we discuss the importance of disturbed redistribution of energy as one of the main reasons for transformation of the acute inflammatory process into the chronic one.

    Rheumatoid arthritis (RA) is a chronic debilitating autoimmune disorder characterized by synovitis that leads to cartilage and bone erosion by invading fibrovascular tissue. Mouse models of RA recapitulate many features of the human disease. Despite the availability of medicines that are highly effective in many patient populations, autoimmune diseases (including RA) remain an area of active biomedical research, and consequently mouse models of RA are still extensively used for mechanistic studies and validation of therapeutic targets. This review aims to integrate morphologic features with model biology and cover the key characteristics of the most commonly used induced and spontaneous mouse models of RA. Induced models emphasized in this review include collagen-induced arthritis and antibody-induced arthritis. Collagen-induced arthritis is an example of an active immunization strategy, whereas antibody- induced arthritis models, such as collagen antibody-induced arthritis and K/BxN antibody transfer arthritis, represent examples of passive immunization strategies. The coverage of spontaneous models in this review is focused on the TNFΔ (ARE) mouse, in which arthritis results from overexpression of TNF-α, a master proinflammatory cytokine that drives disease in many patients.

    Full Text Available Background: The patient with hemoglobinopathy like thalassemia major (TM, bone marrow dysfunction, and sickle cell disease are requiring chronic blood transfusion for their life time to survive. Among these, TM is one of the most common hemoglobinopathy worldwide. Objective: This study is done to assess the quality of life (QOL of the patients with chronic blood transfusion and chelation therapy. Materials and Methods: The QOL scores were obtained through the self-administered SF-36 questionnaire. The study subjects were asked to answer the SF-36 questionnaire once every 3 months. Results: After 6 months, the SF 36 general health mean score was 63.58 ± 12.98 (P < 0.05. The highest mean score was 69.37 ± 11.61. The mean difference after the final reviews was statistically significant. Conclusion: The preponderance of scores used to assess QOL suggests that there is a direct and independent effect on QOL when treated with transfusion and iron-chelation therapy.

    Visit-to-visit blood pressure variability has been shown to be an independent risk factor for cardiovascular diseases. High visit-to-visit blood pressure variability and endothelial dysfunction are observed in patients with chronic kidney disease. It is therefore assumed that high variability in visit-to-visit blood pressure measurements may be associated with endothelial dysfunction in these patients. The present study investigated the associations between visit-to-visit blood pressure variability and renal and endothelial function in patients with chronic kidney disease. We analyzed 150 consecutive patients with predialysis chronic kidney disease who visited our outpatient clinic from January 2006 to December 2010. The study examined the relationships between variability in visit-to-visit systolic blood pressure levels or mean systolic blood pressure (M SBP) and estimated glomerular filtration rate (eGFR) and flow-mediated dilation, an index of endothelial function. Variability in visit-to-visit systolic blood pressure showed a significant negative association with eGFR, independent of age, hemoglobin A1c, low-density lipoprotein (LDL) cholesterol and uric acid, whereas M SBP did not. Similarly, variability in SBP showed a significant negative association with flow-mediated dilation, independent of age, eGFR, HbA1c, LDL cholesterol and M SBP. These data indicate that variability in visit-to-visit blood pressure measurements is associated with impaired renal and endothelial function in patients with chronic kidney disease. This finding suggests that reducing blood pressure fluctuations might have beneficial effects in patients with chronic kidney disease, although this point needs to be addressed by future studies.

  3. Expression profiling reveals novel hypoxic biomarkers in peripheral blood of adult mice exposed to chronic hypoxia.

    Full Text Available Hypoxia induces a myriad of changes including an increase in hematocrit due to erythropoietin (EPO mediated erythropoiesis. While hypoxia is of importance physiologically and clinically, lacunae exist in our knowledge of the systemic and temporal changes in gene expression occurring in blood during the exposure and recovery from hypoxia. To identify these changes expression profiling was conducted on blood obtained from cohorts of C57Bl-10 wild type mice that were maintained at normoxia (NX, exposed for two weeks to normobaric chronic hypoxia (CH or two weeks of CH followed by two weeks of normoxic recovery (REC. Using stringent bioinformatic cut-offs (0% FDR, 2 fold change cut-off, 230 genes were identified and separated into four distinct temporal categories. Class I contained 1 transcript up-regulated in both CH and REC; Class II contained 202 transcripts up-regulated in CH but down-regulated after REC; Class III contained 9 transcripts down-regulated both in CH and REC; Class IV contained 18 transcripts down-regulated after CH exposure but up-regulated after REC. Profiling was independently validated and extended by analyzing expression levels of selected genes as novel biomarkers from our profile (e.g. spectrin alpha-1, ubiquitin domain family-1 and pyrroline-5-carboxylate reductase-1 by performing qPCR at 7 different time points during CH and REC. Our identification and characterization of these genes define transcriptome level changes occurring during chronic hypoxia and normoxic recovery as well as novel blood biomarkers that may be useful in monitoring a variety of physiological and pathological conditions associated with hypoxia.

    A few studies have shown that methotrexate (MTX) use exacerbates liver fibrosis and even leads to liver cirrhosis in rheumatoid arthritis (RA) patients, although the risk is low compared to psoriatics. We therefore conducted a population-based cohort study to investigate the impact of long-term MTX use on the risk of chronic hepatitis C (CHC)-related cirrhosis among RA patients. We analyzed data from the National Health Insurance Research Database in Taiwan and identified 450 incident cases of RA among CHC patients (255 MTX users and 195 MTX non-users) from January 1, 1998 to December 31, 2007. After a median follow-up of more than 5 years since the diagnosis of CHC, a total of 55 (12%) patients developed liver cirrhosis. We did not find an increased risk of liver cirrhosis among CHC patients with long-term MTX use for RA. Furthermore, there was no occurrence of liver cirrhosis among the 43 MTX users with a cumulative dose ≧3 grams after 108 months of treatment. In conclusion, our data showed that long-term MTX use is not associated with an increased risk for liver cirrhosis among RA patients with CHC. However, these results should be interpreted with caution due to potential bias in the cohort. PMID:27609026

    Children with juvenile idiopathic arthritis (JIA) are prone to the problems that can delay their psychosocial development; however, the existing literature has not reached a consensus on the psychological problems related to JIA. A total of 51 children and adolescents with JIA and 75 healthy controls aged 6 to 18 years were examined using the Child Behavioral Checklist (CBCL). Our results represented that 70 percent of JIA group reached “borderline clinical” range or “clinical” range in internalizing problems, while this percentage in the control group was 18 percent. In addition, our results indicated that JIA group has gotten significantly higher scores (more than twofold) in externalizing behaviors compared to control group. Furthermore, children with JIA showed higher rate of anxiety/depression, withdrawal/depression, somatic complaints, rule breaking behaviors, and aggressive behaviors as well as thought and social problems compared to control group (p < 0.001). As a conclusion, children and adolescents with JIA compared to healthy controls may show higher rate of both internalizing and externalizing problems. Furthermore, our novel findings on externalizing, social, and thought problems in JIA warrant further investigation on affected children who may be at greater risk of future psychopathologies.

    Since the first proof of efficacy of TNFalpha blockade, both the number of patients treated worldwide and the number of indications for treatment with TNFalpha blockers have grown steadily. Surprisingly, the profound immunomodulation induced by anti-TNFalpha therapy is associated with a relatively low incidence of immune-related complications such as lupus-like syndromes and demyelinating disease. This contrasts sharply with the prominent induction of autoantibodies such as antinuclear antibodies (ANA) and anti-dsDNA antibodies during TNFalpha blockade. Although this phenomenon has been recognized for several years, the clinical and biological implications are not yet fully understood. In this review, recent studies analysing the effect of TNFalpha blockade (infliximab and etanercept) on the ANA profile in autoimmune arthritis will be discussed. Taken together, these reports indicate that the prominent ANA and anti-dsDNA autoantibody response is 1) not a pure class effect of TNFalpha blockers, 2) independent of the disease background, 3) largely restricted to the induction of short-term IgM anti-dsDNA antibodies, and 4) not associated with other serological or clinically relevant signs of lupus. Nevertheless, a careful follow-up of patients treated with TNFalpha blockers remains mandatory, including monitoring for lupus-like characteristics.

Recently, studies came out detecting this specific alteration also in fast replicating cells, e.g. in blood or skin tissue, often in correlation to specific diseases or - specifically in skin - external stressors such as UV radiation. In this study, we investigated mitochondrial mutagenesis in 69 patients with a chronic alcoholic disease and 46 age matched controls with a moderate drinking behavior. Two different fragments, specific for total and for deleted mtDNA (dmtDNA) were amplified in a duplex-PCR. A subsequent fragment analysis was performed and for relative quantification, the quotient of the peak areas of amplification products specific for deleted and total mtDNA was determined. Additionally, a real time PCR was performed to quantify mtDNA copy number. The relative amount of 4977 bp deleted mtDNA in alcoholics was significantly increased compared to controls. On the other hand, no difference regarding the mtDNA/nuclear DNA ratio in both investigated groups was detected. Additionally, no age dependence could be found nor in alcoholics, neither in the control group. These findings indicate that mtDNA mutagenesis in blood can be influenced by stressors such as alcohol. Ethanol seems to be a significant factor to alter mitochondrial DNA in blood and might be an additional contributor for the cellular aging process.

    Full Text Available Immune mediated demyelinating disease after allogeneic stem cell transplantation is a rare entity with unclear etiology. Acute inflammatory demyelinating polyneuropathy (AIDP has been reported after related and adult unrelated allogeneic stem cell transplantation but no such case has been reported after unrelated cord blood transplantation. We hereby present the first case of AIDP after double umbilical cord blood transplantation (DUCBT. A 55-year-old man with chronic lymphocytic leukemia (CLL received a cord blood transplant for relapsed refractory disease with high risk cytogenetics. On day 221, patient presented with skin rash, tingling in both lower extremites, and ascending paralysis that progressed rapidly over the course of 2 days. The workup resulted in a diagnosis of AIDP and administration of intravenous immunoglobulins plus steroids was initiated. Motor and sensory powers were fully recovered and his chronic GVHD was managed for several months with single agent sirolimus.

    Introduction: Polymorphonuclear neutrophil leukocytes (PMNL) have an important defensive role against various microorganisms and other agents, but by liberating various substances, first of all the superoxide anion (O 2¯), they can damage the bronchial mucosa and influence the development of bronchial inflammation which is the fundamental of bronchial hyperreactivity (BHR). Objective: to show the role of the PMNL for development and level of BHR in patients with chronic obstructive pulmonary disease (COPD). Material and methods: We observed 160 patients with COPD treated in Clinic for Pulmonary Diseases and TB “Podhrastovi” Sarajevo during three years :from 2012 to 2014. They were divided into groups and subgroups according to the first registration of BHR in the course of illness and to the number of exacerbations of the disease in one year. The number of blood PMNL was measured in a stable state of disease at the begging and at the end of investigation. Results: The number of blood PMNL was significantly greater in patients with 3 or more exacerbations per one year (p <0.01). Patients with BHR had significantly greater number blood PMNL than patients without BHR (p< 0.05). Patients with 3 exacerbations per year had a statistically significant increase of number of PMNL between first and last examination (p<0.01). Conclusion: There is statistically significant correlation between the number of blood PMNL and the level of BHR in COPD, but future examination need to be done to determine real role and mode of action of PMNL for these processes.

    1 The present study was undertaken to characterize the spectrum of arachidonic acid metabolites present in synovial effusions of patients with rheumatoid or psoriatic arthritis, and to compare changes in their concentration following a short-term treatment with 6α-methyl-prednisolone (6-MeP: 4-8 mg/day) or indoprofen (1.2 g/day), a nonsteroidal anti-inflammatory agent with proven synovial prostaglandin inhibitory effect. 2 Measurements of prostaglandin E2 (PGE2), thromboxane (TX) B2, 6-keto-PGF1α and PGF2α were performed by radioimmunoassay techniques in synovial effusions obtained from 23 patients, and validated by thin-layer chromatographic analysis of the extracted immunoreactivity. 3 PGE2 and TXB2 accounted for more than 60% of the total immunoreactivity in untreated patients. The absence of any constant ratio between the different arachidonic acid metabolites detected in synovial fluid is consistent with a heterogeneous cellular origin of these compounds. 4 Indoprofen treatment was associated with a consistent reduction of synovial prostaglandin and thromboxane concentrations, ranging from 36% in the case of 6-keto-PGF1α to 90% in the case of PGE2. 5 In contrast, 6-MeP caused opposite changes on different metabolites originating via the cyclo-oxygenase pathway. Thus, 6-keto-PGF1α concentrations were reduced by 35%, PGF2α concentrations were increased by 30%, while PGE2 and TXB2 were unchanged following 6-MeP. 6 Although the mechanism(s) underlying the failure of 6-MeP to reduce synovial PGE2 and TXB2 levels are uncertain, the results of the present study clearly indicate that therapeutic doses of steroidal and nonsteroidal anti-inflammatory drugs cause quite distinct changes in arachidonic acid metabolism, which might be relevant to their specific therapeutic actions and side-effects.

    Full Text Available AbstractBackground. Rheumatoid arthritis (RA is commonly accompanied by pain that is discordant with the degree of peripheral pathology. Very little is known about the cerebral processes involved in pain processing in RA. Here we investigated resting-state brain connectivity associated with prolonged pain in RA. Methods. 24 RA subjects and 19 matched controls were compared with regard to both behavioral measures of pain perception and resting-resting state fMRI data acquired subsequently to fMRI sessions involving pain stimuli. The resting-state fMRI brain connectivity was investigated using 159 seed regions located in cardinal pain processing brain regions. Additional principal component based multivariate pattern analysis of the whole brain connectivity pattern was carried out in a data driven analysis to localize group differences in functional connectivity. Results. When RA patients were compared to controls, we observed significantly lower pain resilience for pressure on the affected finger joints (i.e. P50-joint and an overall heightened level of perceived global pain in RA patients. Relative to controls, RA patients displayed increased brain connectivity predominately for the supplementary motor areas, mid-cingulate cortex and the primary sensorimotor cortex. Additionally, we observed an increase in brain connectivity between the insula and prefrontal cortex as well as between anterior cingulate cortex and occipital areas for RA patients. None of the group differences in brain connectivity were significantly correlated with behavioral parameters.Conclusion. Our study provides experimental evidence of increased connectivity between frontal midline regions that are implicated in affective pain processing and bilateral sensorimotor regions in RA patients.

    2012-01-01

    Full Text Available This case report describes the successful treatment of chronic headache from intracranial hypotension with bilateral transforaminal (TF lumbar epidural blood patches (EBPs. The patient is a 65-year-old male with chronic postural headaches. He had not had a headache-free day in more than 13 years. Conservative treatment and several interlaminar epidural blood patches were previously unsuccessful. A transforaminal EBP was performed under fluoroscopic guidance. Resolution of the headache occurred within 5 minutes of the procedure. After three months without a headache the patient had a return of the postural headache. A second transforaminal EBP was performed again with almost immediate resolution. The patient remains headache-free almost six months from the time of first TF blood patch. This is the first published report of the use of transforaminal epidural blood patches for the successful treatment of a headache lasting longer than 3 months.

    Respiratory-induced changes in the partial pressures of arterial carbon dioxide (PaCO2) and oxygen (PaO2) play a major role in cerebral blood flow (CBF) regulation. Elevations in PaCO2 (hypercapnia) lead to vasodilatation and increases in CBF, whereas reductions in PaCO2 (hypocapnia) lead to vasoconstriction and decreases in CBF. A fall in PaO2 (hypoxia) below a certain threshold (balance between the myriad of vasodilators and constrictors derived from the endothelium, neuronal innervations and perfusion pressure. This review examines the extent and mechanisms by which hypoxia regulates CBF. Particular focus will be given to the marked influence of hypoxia associated with exposure to high altitude and chronic lung disease. The associated implications of these hypoxia-induced integrative alterations for the regulation of CBF are discussed, and future avenues for research are proposed.

    Full Text Available Background. Cell signaling via Toll-like receptors (TLRs leads to synovial inflammation in rheumatoid arthritis (RA. We aimed to assess effects of TLR2 and TLR4 stimulation on proinflammatory cytokine production by peripheral blood mononuclear cells (PBMCs from patients with recent-onset RA, osteoarthrosis (OA, and healthy control (HC. Methods. PBMCs were stimulated with LPS, biglycan and cytokine mix. Cytokines were analyzed in supernatants with ELISA. Expression of toll-like receptors mRNA in leukocytes was analyzed using real-time qPCR. Results. PBMCs from RA patients spontaneously produced less IL-6 and TNFα than cells from OA and HC subjects. LPS increased cytokines' production in all groups. In RA patients increase was dramatic (30 to 48-fold and 17 to 31-fold, for respective cytokines compared to moderate (2 to 8-fold in other groups. LPS induced 15-HETE generation in PBMCs from RA (mean 251% and OA patients (mean 43%, although only in OA group, the increase was significant. TLR2 and TLR4 gene expressions decreased in response to cytokine mix, while LPS enhanced TLR2 expression in HC and depressed TLR4 expression in OA patients. Conclusion. PBMCs from recent-onset RA patients are overresponsive to stimulation with bacterial lipopolysaccharide. TLR expression is differentially regulated in healthy and arthritic subjects.

    Full Text Available Patients with rheumatoid arthritis (RA have a higher risk for atherosclerosis. There is no clinical information about scavenger receptor CD36 and the development of subclinical atherosclerosis in patients with RA. The aim of this study was to evaluate the association between membrane expression of CD36 in peripheral blood mononuclear cells (PBMC and carotid intima-media thickness (cIMT in patients with RA. Methods. We included 67 patients with RA from the Rheumatology Department of Hospital Civil “Dr. Juan I. Menchaca,” Guadalajara, Jalisco, Mexico. We evaluated the cIMT, considering subclinical atherosclerosis when >0.6 mm. Since our main objective was to associate the membrane expression of CD36 with subclinical atherosclerosis, other molecules related with cardiovascular risk such as ox-LDL, IL-6, and TNFα were tested. Results. We found low CD36 membrane expression in PBMC from RA patients with subclinical atherosclerosis (P<0.001. CD36 mean fluorescence intensity had negative correlations with cIMT (r = −0.578, P<0.001, ox-LDL (r = −0.427, P = 0.05, TNFα (r = −0.729, P<0.001, and IL-6 (r = −0.822, P<0.001. Conclusion. RA patients with subclinical atherosclerosis showed low membrane expression of CD36 in PBMC and increased serum proinflammatory cytokines. Further studies are needed to clarify the regulation of CD36 in RA.

    Full Text Available Objective. The purpose of the current study was to investigate nimesulide effects on prostaglandin E 2 concentration in blood serum and some parameters of the cardiovascular system in pts with RA during a 6-month period. Materials and methods. 40 RA pts were studied, 20 of them took 200 mg of nimesulide per day (24 hours in combination with low doses of metatrexate (7.5-10.0 mg per week. The pts were studied for 6 months. The content of E2 prostaglandin in blood serum was evaluated and estimated by means of the immuneenzymic method in 20 pts who took 200 mg of nimesulide per day (24 hours in comparison with 20 pts who took 100 mg of sodium diclofenac per day. The cardiovascular system was evaluated and estimated by means of screening examinations and after the 6-month treatment period by means of 24-hour monitoring of arterial blood pressure, ECG-monitoring and echocardioscopy. Results. In case of the nimesulide treatment the above RA pts did not show reliable reduction of PGE- 2 in blood serum as compared with sodium dicofenac after a 5 day and the 6-month treatment. This showed the selective effect of nimesulide in relation to COX-2. As far as the parameters of the cardiovascular system are concerned, no negative dynamics were revealed at the background of nimesulide treatment . It was revealed that nimesulide is quite effective and has good tolerance.

    Esteban R Fernández

    Full Text Available Numerous abnormalities of the peripheral blood T cell compartment have been reported in human chronic Trypanosoma cruzi infection and related to prolonged antigenic stimulation by persisting parasites. Herein, we measured circulating lymphocytes of various phenotypes based on the differential expression of CD19, CD4, CD27, CD10, IgD, IgM, IgG and CD138 in a total of 48 T. cruzi-infected individuals and 24 healthy controls. Infected individuals had decreased frequencies of CD19+CD27+ cells, which positively correlated with the frequencies of CD4+CD27+ cells. The contraction of CD19+CD27+ cells was comprised of IgG+IgD-, IgM+IgD- and isotype switched IgM-IgD- memory B cells, CD19+CD10+CD27+ B cell precursors and terminally differentiated CD19+CD27+CD138+ plasma cells. Conversely, infected individuals had increased proportions of CD19+IgG+CD27-IgD- memory and CD19+IgM+CD27-IgD+ transitional/naïve B cells. These observations prompted us to assess soluble CD27, a molecule generated by the cleavage of membrane-bound CD27 and used to monitor systemic immune activation. Elevated levels of serum soluble CD27 were observed in infected individuals with Chagas cardiomyopathy, indicating its potentiality as an immunological marker for disease progression in endemic areas. In conclusion, our results demonstrate that chronic T. cruzi infection alters the distribution of various peripheral blood B cell subsets, probably related to the CD4+ T cell deregulation process provoked by the parasite in humans.

    We have little information on chronic graft-versus-host disease (GVHD) after cord blood transplantation (CBT). We investigated its clinical features in 1072 Japanese patients with hematologic malignancies who received a transplant through the Japan Cord Blood Bank Network. The primary end point was to investigate the incidence of any chronic GVHD. Median age of the patients was 33 years (range, 0-79 years). The cumulative incidence of chronic GVHD 2 years after transplantation was 28%. Chronic GVHD was fatal in 29 patients. Multivariate analysis demonstrated that development of chronic GVHD was favorably associated with both overall survival and event-free survival. Multivariate analysis identified risk factors of chronic GVHD: higher patient body weight, higher number of mismatched antigens for GVHD direction, myeloablative preparative regimen, use of mycophenolate mofetil in GVHD prophylaxis, and development of grades II to IV acute GVHD. Although chronic GVHD is a significant problem after CBT, it is associated with improved survival, perhaps due to graft-versus-malignancy effects.

    Full Text Available Objective. Given the role of TNF-α in Rheumatoid Arthritis (RA we decided to define the characteristics of the TNF- α synthesis by peripheral blood mononuclear cells (PBMNCs obtained from active-aggressive RA patients giving a particular attention to the modulation of the expression of two fundamental proteins in TNF-α mRNA stability regulation, Tristetraprolin (TTP and HuR. Methods. 11 RA patients with active disease were enrolled in the study before their entry in 2 double blind protocols: Infliximab versus MTX and Etanercept versus MTX. 9 healthy blood donors were taken as controls. PBMNCs obtained by Ficoll centrifugation and plastic adherence were stimulated with lipopolysaccharide (LPS and TNF-α was measured in the supernatant during 8 hours by ELISA. At each time point the cells were harvested and analysed for TNF- α, TTP and HuR mRNA expression by semi-quantitative PCR. Results. MNCs TNF-α secretion after LPS stimulation did not differ significantly between RA and control subjects, even if a tendency towards a more prompt response was observed in the patients. More importantly only the DMARDs responsive patients (DAS <3.7 at the 6th month, with a minimal reduction of 1.2 points disclosed precociously (at the first month a significant change in the profile of TNF-α secretion and maintained it until the 6th month. The “normalization” of the synthetic behaviour was accompanied by the resetting in the regulation of the expression of the TTP, that appeared significantly different in the patients before and after therapy. Conclusions. Independently from the type of therapy, responsive patients demonstrate a rapid change in the cellular biology at the systemic level that might drive the resolution of the phlogistic process at the synovial level.

    In 90% of patients with rheumatoid arthritis (RA), the joints of the hand are affected. Studies of grip strength training have not indicated a negative effect on disease activity after training. Introduction of ultrasound Doppler (USD) to measure increased blood flow induced by inflammation has made it possible to investigate the direct effect on blood supply in the synovium after training. In this case-control study, 24 patients with RA with USD activity in the wrist joint participated. The USD activity was measured by the color fraction (CF) (CF = colored pixels/total number of pixels in ROI). Twenty-four patients were assigned to an 8-week grip strength training program. At baseline and after 8 weeks of training, an USD examination of the wrist joint was performed. In the training group, we measured grip strength and pain in the wrist joint. Six patients withdrew from the training because of pain or change in medication. Eighteen patients served as control group. There was a modest, not significant, decrease in the CF in response to training (1.86%; P = 0.08). Grip strength increased 8.8% after training (P = 0.055). Pain in motion deceased after training (P = 0.04). No difference in the CF was seen between the training and control groups, neither at baseline nor at follow-up (P = 0.82 and P = 0.48). Patients withdrawing from training had a significantly higher CF than the other patients (P > 0.001). The results in this study might indicate that the flow in the synovium assessed by USD is not affected by grip strength training.

    Full Text Available Periodic assessment of gene expression for diagnosis and monitoring in rheumatoid arthritis (RA may provide a readily available and useful method to detect subclinical disease progression and follow responses to therapy with disease modifying anti-rheumatic agents (DMARDs or anti-TNF-α therapy. We used quantitative real-time PCR to compare peripheral blood gene expression profiles in active ("unstable" RA patients on DMARDs, stable RA patients on DMARDs, and stable RA patients treated with a combination of a DMARD and an anti-TNF-α agent (infliximab or etanercept to healthy human controls. The expression of 48 inflammatory genes were compared between healthy controls (N=122, unstable DMARD patients (N=18, stable DMARD patients (N=26, and stable patients on combination therapy (N=20. Expression of 13 genes was very low or undetectable in all study groups. Compared to healthy controls, patients with unstable RA on DMARDs exhibited increased expression of 25 genes, stable DMARD patients exhibited increased expression of 14 genes and decreased expression of five genes, and combined therapy patients exhibited increased expression of six genes and decreased expression of 10 genes. These findings demonstrate that active RA is associated with increased expression of circulating inflammatory markers whereas increases in inflammatory gene expression are diminished in patients with stable disease on either DMARD or anti-TNF-α therapy. Furthermore, combination DMARD and anti-TNF-α therapy is associated with greater reductions in circulating inflammatory gene expression compared to DMARD therapy alone. These results suggest that assessment of peripheral blood gene expression may prove useful to monitor disease progression and response to therapy.

    The complement mediated binding of prepared antibody//sup 3/H-dsDNA immune complexes to the red blood cells obtained from a number of patient populations has been investigated. Patients with solid tumors have binding activity similar to that seen in a normal group of individuals. However, a significant fraction of patients with systemic lupus erythematosus, rheumatoid arthritis, and hematologic malignancies have lowered binding activity compared with normal subjects. Quantitative studies indicate the lowered activity probably arises due to a decrease in complement receptors on the respective red blood cells. The potential importance and implications of these findings are briefly discussed.

    AIM: To determine the prevalences of TTV and HGV infections among blood donors and patients with chronic liver disease in Korea, to investigate the association of TTV and HGV infections with blood transfusion, and to assess the correlation between TTV and HGV viremia and hepatic damage.METHODS: A total of 391 serum samples were examined in this study. Samples were obtained from healthy blood donors (n= 110), hepatitis B surface antigen (HBsAg)-positive donors (n=112), anti-hepatitis C virus (anti-HCV)-positive donors (n=69), patients with type B chronic liver disease (n=81), and patients with type C chronic liver disease (n= 19).TTV DNA was detected using the hemi-nested PCR. HGV RNA was tested using RT-PCR. A history of blood transfusion and serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were also determined.RESULTS: TTV DNA was detected in 8.2 % of healthy blood donors, 16.1% of HBsAg-positive donors, 20.3 % of antiHCV-positive donors, 21.0 % of patients with type B chronic liver disease, and 21.1% of patients with type C chronic liver disease. HGV RNA was detected in 1.8 % of healthy blood donors, 1.8 % of HBsAg-positive donors, 17.4 % of anti-HCV-positive donors, 13.6% of patients with type B chronic liver disease, and 10.5% of patients with type C chronic liver disease. The prevalence of TTV and HGV infections in HBV- or HCV-positive donors and patients was significantly higher than in healthy blood donors (P<0.05),except for the detection rate of HGV in HBsAg-positive donors which was the same as for healthy donors. There was a history of transfusion in 66.7% of TTV DNA-positive patients and 76.9% of HGV RNA-positive patients (P<0.05). No significant increase in serum ALT and AST was detected in the TTV- or HGV-positive donors and patients.CONCLUSION: TTV and HGV infections are more frequently found in donors and patients infected with HBV or HCV than in healthy blood donors. However, there is no significant

    The association between juvenile arthritis and uveitis is reviewed. Some children with the HLA-B27 related spondyloarthropathies develop anterior uveitis. About 20% of patients with juvenile rheumatoid arthritis (JRA) who are negative for IgM rheumatoid factor develop a frequently bilateral, nongranulomatous chronic anterior uveitis. Risk factors for uveitis in JRA patients are: female gender, pauciarticular onset of arthritis, presence of circulating antinuclear antibodies, and the antigens HLA-DW5 and HLA-DPw2. Uveitis is rare after seven years or more have elapsed from the onset of arthritis. The visual prognosis in patients with uveitis is good in 25% and fair in 50%. The remaining 25% develop visual impairment from complicated cataract and/or secondary inflammatory glaucoma. The potential benefit of cytotoxic agents in the treatment of intractable uveitis is outweighed by the risk of serious side effects. The management of secondary inflammatory glaucoma is unsatisfactory, but the results of treatment of complicated cataracts by lensectomy-vitrectomy are good.

    Current diagnostic methods in differentiating septic from non-septic arthritis are time-consuming (culture) or have limited sensitivity (Gram stain). Microcalorimetry is a novel method that can rapidly detect microorganisms by their heat production. We investigated the accuracy and time to detection of septic arthritis by using microcalorimetry. Patients older than 18 years of age with acute arthritis of native joints were prospectively included. Synovial fluid was aspirated and investigated by Gram stain, culture and microcalorimetry. The diagnosis of septic arthritis and non-septic arthritis were made by experienced rheumatologists or orthopaedic surgeons. Septic arthritis was diagnosed by considering the finding of acute arthritis together with findings such as positive Gram stain or positive culture of synovial fluid or positive blood culture. The sensitivity and specificity for diagnosing septic arthritis and the time to positivity of microcalorimetry were determined. Of 90 patients (mean age 64 years), nine had septic arthritis, of whom four (44 %) had positive Gram stain, six (67 %) positive synovial fluid culture and four (44 %) had positive blood culture. The sensitivity of microcalorimetry was 89 %, the specificity was 99 % and the mean detection time was 5.0 h (range, 2.2-8.0 h). Microcalorimetry is an accurate and rapid method for the diagnosis of septic arthritis. It has potential to be used in clinical practice in diagnosing septic arthritis.

    The study examined whether deficits in cardiac output and blood volume in a CFS (chronic fatigue syndrome) cohort were present and linked to illness severity and sedentary lifestyle. Follow-up analyses assessed whether differences in cardiac output levels between CFS and control groups were corrected by controlling for cardiac contractility and TBV (total blood volume). The 146 participants were subdivided into two CFS groups based on symptom severity data, severe (n=30) and non-severe (n=26), and two healthy non-CFS control groups based on physical activity, sedentary (n=58) and non-sedentary (n=32). Controls were matched to CFS participants using age, gender, ethnicity and body mass. Echocardiographic measures indicated that the severe CFS participants had 10.2% lower cardiac volume (i.e. stroke index and end-diastolic volume) and 25.1% lower contractility (velocity of circumferential shortening corrected by heart rate) than the control groups. Dual tag blood volume assessments indicated that the CFS groups had lower TBV, PV (plasma volume) and RBCV (red blood cell volume) than control groups. Of the CFS subjects with a TBV deficit (i.e. > or = 8% below ideal levels), the mean+/-S.D. percentage deficit in TBV, PV and RBCV were -15.4+/-4.0, -13.2+/-5.0 and -19.1+/-6.3% respectively. Lower cardiac volume levels in CFS were substantially corrected by controlling for prevailing TBV deficits, but were not affected by controlling for cardiac contractility levels. Analyses indicated that the TBV deficit explained 91-94% of the group differences in cardiac volume indices. Group differences in cardiac structure were offsetting and, hence, no differences emerged for left ventricular mass index. Therefore the findings indicate that lower cardiac volume levels, displayed primarily by subjects with severe CFS, were not linked to diminished cardiac contractility levels, but were probably a consequence of a co-morbid hypovolaemic condition. Further study is needed to address

    Excess dietary nitrogen (EDN) is commonly expected in dairy herds, but no data are available regarding its consequences on cattle immunity. In this study neutrophil functions were assessed during EDN in steers. In experiment 1, 4 one-month periods, 4 diets [16% crude protein (CP; DM basis), 20% CP based on soybean meal, 20% CP based on urea, and 24% CP based on urea and soybean meal], and 4 steers were included in a crossover design to determine the effects of a chronic excess. In experiment 2, the repercussions of an acute excess were assessed with 2 periods of 10 d, the same 4 steers, and 2 diets containing 14 and 20% CP. Sampling was done during the fourth week of each period in experiment 1, and on d 0, 1, 2, 3, 7, and 9 of each period in experiment 2. Individual blood biochemistry parameters were measured and neutrophil factors, such as counts, recovery after isolation, surface expression of CD11b and CD62L, phagocytosis, diapedesis, reactive oxygen species (ROS) production, and bacteria killing, were determined. Data were analyzed by general linear models of R, with period, diet or biochemical component, and animal as explanatory variables. The outcome variables were biochemical or immune variables. The variables diet, period, and animal were forced as fixed effects. Data collected over the entire period of experiment 2 were pooled. Several multiples linear regressions or ANOVA were performed and a Bonferroni correction was applied. In experiment 2 (acute EDN), neutrophil counts were negatively associated with nitrogen intake, conversely to CD62L expression. The observed relative neutropenia may be due to neutrophil margination because CD62L-expressing neutrophils are more likely to stick to endothelium. Interestingly, ROS production was changed by EDN: chronic EDN (experiment 1) was negatively associated with opsonized zymozan (OZ)-induced ROS production and acute EDN (experiment 2) with spontaneous ROS production. For chronic EDN, ROS production upon

    Full Text Available The purpose of this study was to determine whether chronic periodontitis can stand behind the modifications observed in the salivary and blood concentration of some bivalent cations (Calcium, Magnesium, Zinc and Copper. The investigations were performed on an experimental group of 30 patients with clinically-onset chronic periodontitis, and on a control one, including 30 periodontitisfree patients. Total saliva samples were obtained as “first time in the morning” then weighed and processed. Cations were read on an Atomic Absorption Spectrophotometer (Calcium, Copper and Zinc and also by Ion Chromatography (Magnesium. The same patients were required to undergo laboratory blood tests for Calcium, Magnesium and Zinc. The obtained data were normalised, then statistically interpreted using two-tailed heteroscedastic t-Student tests. The results obtained showed a clear connection of blood magnesium, and also of salivary calcium, magnesium, zinc and copper, to chronic periodontitis. Salivary cations are therefore related to the local inflammatory status and associated pathological processes. Blood magnesium could be affected by chronic inflammation.

    In 99 patients with congenital heart defects or chronic respiratory disease without clinical symptoms of disturbances in peripheral circulation, resting and maximal blood flow in the anterior tibial muscle of both extremities were investigated 2.7 yrs (average) after cardiac catheterization. The method used involved /sup 133/Xe clearance. Resting blood flow was normal and no difference could be demonstrated between the extremity originally used for catheterization and the contralateral control extremity. No disturbance in maximal blood flow could be proved in the extremity used for catheterization by the venous route only. Maximal blood flow was significantly lower in that extremity where the femoral artery had been catheterized or cannulated for pressure measurement and blood sampling. The disturbance in maximal flow was shown regardless of whether the arterial catheterization involved the Seldinger percutaneous technique, arteriotomy, or mere cannulation of the femoral artery. The values in the involved extremity did not differ significantly from the values in a healthy population.

    Full Text Available BACKGROUND & OBJECTIVES: Patients with Rheumatoid Arthritis (R.A. have a marked increase in Carotid Atherosclerosis independent of traditional risk factors like family history of myocardial infarction in first degree male relatives younger than 55 years of age or first degree female relatives younger than 65 years of age, smoking, hypertension (D efined as blood pressure of 140/90 mm hg or higher, diabetes mellitus and fasting serum cholesterol levels including age. Chronic inflammation and possibly disease severity and duration are atherogenic in Rheumatoid Arthritis patients. Preclinical disease may also be identified by using ultrasonography to determine carotid intimal - media thickness, an indirect measure of atherosclerosis. The common carotid artery Intima media thickness in Rheumatoid Arthritis patients is positively associated with disease duration, Early Rheumatoid Arthritis (D uration less or = 1 year is associated with lesser Intima media thickness than was Rheumatoid Arthritis of longer duration. Increased carotid artery Intima media thickness and the presence of carotid plaque are associated with markers of systemic inflammation in patients with Rheumatoid Arthritis and in healthy subjects. OBJECTIVE OF THE STUDY: To determine preclinical atherosclerosis occurring prematurely in patients of Rheumatoid Arthritis by ultrasonograhic measurement Common Carotid Artery Intima media thickness and to evaluate the risk factors associated with arterial intima media thickness in patient of Rheumatoid Arthritis. RESULTS: In RA patients, common carotid artery IMT was significantly higher when compared to healthy controls (0.65 ± 0.06 v/s 0.57 ± 0.049 and was significantly associated with the duration of RA, swollen joint count and erosive changes on hand x - ray independently of other confounding variables. CONCLUSION: Patients with rheumatoid arthritis have a marked increase in carotid atherosclerosis independent of traditional risk factors

    Juvenile idiopathic arthritis is the most common rheumatic disease in childhood. It is a chronic inflammatory disease associated with arthritis of unknown etiology that begins before the age of 16 and persists for longer than 6 weeks. In this report, the case of a child who suffered recurrent alternative hip arthritis with bilateral hip arthritis is examined, in which he was finally diagnosed as suffering from Juvenile idiopathic arthritis. A 14-year-old boy of Taiwanese origin presented with a normal birth and developmental history. At the age of 10, right-side hip joint pain was experienced, which later migrated to the left side. On further inspection, synovium hypertrophy, cartilage erosion and hip turbid fluid accumulation were found and aseptic arthritis was presumed to be the primary cause. However, after re-examining both his clinical history and presentation, Juvenile idiopathic arthritis was the final diagnosis. Any child presenting with repeat joint swelling are at risk of Juvenile idiopathic arthritis. This is still to be the case if symptoms recede or heal and no initial diagnosis is made. Therefore, a better understanding of the risk of recurrent arthritis is needed. It cannot be emphasized strongly enough that Juvenile idiopathic arthritis should be suspected at all times when a child suffers from recurrent aseptic arthritis of the hip joint.

    Adipokines have been reported to be involved in the regulation of various physiological processes, including the immune response. Rheumatoid arthritis (RA) is an example of a systemic immune disease that causes chronic inflammation of the synovium and bone destruction in the joint. Recent therapeutic strategies based on the understanding of the role of cytokines and cellular mechanisms in RA have improved our understanding of angiogenesis. On the other hand, endogenous endothelial progenitor cells, which are a population isolated from peripheral blood monocytes have recently been identified as a homing target for pro-angiogeneic factor and vessel formation. In this review, we summarize the effects of common adipokines, such as adiponectin, leptin and resistin in RA pathogenesis and discuss other potential mechanisms of relevance for the therapeutic treatment of RA.

    Full Text Available BACKGROUND: T-helper (Th 22 is involved in the pathogenesis of inflammatory diseases. The roles of Th22 cells in the pathophysiological of ankylosing spondylitis (AS and rheumatoid arthritis (RA remain unsettled. So we examined the frequencies of Th22 cells, Th17 cells and Th1 cells in peripheral blood (PB from patients with AS and patients with RA compared with both healthy controls as well as patients with osteoarthritis. DESIGN AND METHODS: We studied 32 AS patients, 20 RA patients, 10 OA patients and 20 healthy controls. The expression of IL-22, IL-17 and IFN-γ were examined in AS, RA, OA patients and healthy controls by flow cytometry. Plasma IL-22 and IL-17 levels were examined by enzyme-linked immunosorbent assay. RESULTS: Th22 cells, Th17 cells and interleukin-22 were significantly elevated in AS and RA patients compared with OA patients and healthy controls. Moreover, Th22 cells showed positive correlation with Th17 cells as well as interleukin-22 in AS and RA patients. However, positive correlation between IL-22 and Th17 cells was only found in AS patients not in RA patients. In addition, the percentages of both Th22 cells and Th17 cells correlated positively with disease activity only in RA patients not in AS patients. CONCLUSIONS: The frequencies of both Th22 cells and Th17 cells were elevated in PB from patients with AS and patients with RA. These findings suggest that Th22 cells and Th17 cells may be implicated in the pathogenesis of AS and RA, and Th22 cells and Th17 cells may be reasonable cellular targets for therapeutic intervention.

    This study aimed to assess effects of chronic occupational exposure on immune status in Mayak workers chronically exposed to ionizing radiation (IR). The study cohort consists of 77 workers occupationally exposed to external gamma-rays at total dose from 0.5 to 3.0 Gy (14 individuals) and workers with combined exposure (external gamma-rays at total dose range 0.7-5.1 Gy and internal alpha-radiation from incorporated plutonium with a body burden of 0.3-16.4 kBq). The control group consists of 43 age- and sex-matched individuals who never were exposed to IR, never involved in any cleanup operations following radiation accidents and never resided at contaminated areas. Enzyme-linked immunoassay and flow cytometry were used to determine the relative concentration of lymphocytes and proteins. The concentrations of T-lymphocytes, interleukin-8 and immunoglobulins G were decreased in external gamma-exposed workers relative to control. Relative concentrations of NKT-lymphocytes, concentrations of transforming growth factor-β, interferon gamma, immunoglobulins A, immunoglobulins M and matrix proteinase-9 were higher in this group as compared with control. Relative concentrations of T-lymphocytes and concentration of interleukin-8 were decreased, while both the relative and absolute concentration of natural killers, concentration of immunoglobulins A and M and matrix proteinase-9 were increased in workers with combined exposure as compared to control. An inverse linear relation was revealed between absolute concentration of T-lymphocytes, relative and absolute concentration of T-helpers cells, concentration of interferon gamma and total absorbed dose from external gamma-rays in exposed workers. For workers with incorporated plutonium, there was an inverse linear relation of absolute concentration of T-helpers as well as direct linear relation of relative concentration of NKT-lymphocytes to total absorbed red bone marrow dose from internal alpha-radiation.

    This study tested the hypothesis that inducing hyperinsulinemia and hyperglycemia in dogs, by infusing glucose chronically intravenously, would increase tubular sodium reabsorption and cause hypertension. Glucose was infused for 6 days (14 mg.kg(-1).min(-1) iv) in five uninephrectomized (UNX) dogs. Mean arterial pressure (MAP) and renal blood flow (RBF) were measured 18 h/day using DSI pressure units and Transonic flow probes, respectively. Urinary sodium excretion (UNaV) decreased significantly on day 1 and remained decreased over the 6 days, coupled with a significant, sustained increase in RBF, averaging approximately 20% above control on day 6. Glomerular filtration rate and plasma renin activity (PRA) also increased. However, although MAP tended to increase, this was not statistically significant. Therefore, the glucose infusion was repeated in six dogs with 70% surgical reduction in kidney mass (RKM) and high salt intake. Blood glucose and plasma insulin increased similar to the UNX dogs, and there was significant sodium retention, but MAP still did not increase. Interestingly, the increases in PRA and RBF were prevented in the RKM dogs. The decrease in UNaV, increased RBF, and slightly elevated MAP show that glucose infusion in dogs caused a sustained increase in tubular sodium reabsorption by a mechanism independent of pressure natriuresis. The accompanying increase in PRA, together with the failure of either RBF or PRA to increase in the RKM dogs, suggests the site of tubular reabsorption was before the macula densa. However, the volume retention and peripheral edema suggest that systemic vasodilation offsets any potential renal actions to increase MAP in this experimental model in dogs.

    Full Text Available Introduction: Patients with chronic kidney disease (CKD show an increase in bowel aerobic bacteria that produce uremic toxins and decreased anaerobic bacteria as bifidobacteria and lactobacillus. The latter can be used as probiotics. The probiotic with greater availability in Mexico, is the lactobacillus casei shirota (LcS, currently there is no known LcS specified dose that produces a benefit to the patient with CKD. Objective: To determine the effectiveness of two different LcS doses in achieving a decrease in urea concentrations of at least 10% in patients with KDOQI stage 3 and stage 4 CKD. Metodology: A simple randomized, controlled clinical trial. Outpatients treated at the National Institute of Medical Sciences and Nutrition Salvador Zubiran in Mexico D.F. Patients were provided the LcS, as follows: Group A: 8 x 10(9 colony-forming units (CFU and Group B: 16 x 10(9 CFU. Patients were followed-up for eight weeks, and baseline and final samples were obtained to calculate the basal and final concentrations, respectively, of blood urea and serum creatinine (CrS. During the follow-up, both groups consumed a diet of 30 kcal/kg/weight and 0.8 g/kg/weight of protein, and a food diary was made to assess both the adherence to the diet and LcS. Results: Thirty patients with CKD were evaluated. When analyzing the percentage change between the different doses, a decrease > 10% was found in the blood urea concentrations for patients treated with the 16 x 10(9 dose, which was significant with respect to the baseline measurement. Conclusion: There was a > 10% decrease in the serum urea concentrations with LcS in patients with stage 3 and 4 CRF.

  10. Biomarkers for early and late stage chronic allograft nephropathy by proteogenomic profiling of peripheral blood.

    Sunil M Kurian

    Full Text Available BACKGROUND: Despite significant improvements in life expectancy of kidney transplant patients due to advances in surgery and immunosuppression, Chronic Allograft Nephropathy (CAN remains a daunting problem. A complex network of cellular mechanisms in both graft and peripheral immune compartments complicates the non-invasive diagnosis of CAN, which still requires biopsy histology. This is compounded by non-immunological factors contributing to graft injury. There is a pressing need to identify and validate minimally invasive biomarkers for CAN to serve as early predictors of graft loss and as metrics for managing long-term immunosuppression. METHODS: We used DNA microarrays, tandem mass spectroscopy proteomics and bioinformatics to identify genomic and proteomic markers of mild and moderate/severe CAN in peripheral blood of two distinct cohorts (n = 77 total of kidney transplant patients with biopsy-documented histology. FINDINGS: Gene expression profiles reveal over 2400 genes for mild CAN, and over 700 for moderate/severe CAN. A consensus analysis reveals 393 (mild and 63 (moderate/severe final candidates as CAN markers with predictive accuracy of 80% (mild and 92% (moderate/severe. Proteomic profiles show over 500 candidates each, for both stages of CAN including 302 proteins unique to mild and 509 unique to moderate/severe CAN. CONCLUSIONS: This study identifies several unique signatures of transcript and protein biomarkers with high predictive accuracies for mild and moderate/severe CAN, the most common cause of late allograft failure. These biomarkers are the necessary first step to a proteogenomic classification of CAN based on peripheral blood profiling and will be the targets of a prospective clinical validation study.

    Full Text Available Increased blood pressure variability (BPV, which can be experimentally induced by sinoaortic denervation (SAD, has emerged as a new marker of the prognosis of cardiovascular and renal outcomes. Considering that increased BPV can lead to organ-damage, the goal of the present study was to evaluate the effects of SAD on renal function in an experimental model of chronic kidney disease (CKD. SAD was performed in male Wistar rats 2 weeks before 5/6 nephrectomy and the animals were evaluated 4 weeks after the induction of CKD. Our data demonstrated that BPV was increased in SAD and CKD animals and that the combination of both conditions (SAD+CKD exacerbated BPV. The baroreflex sensitivity index was diminished in the SAD and CKD groups; this reduction was more pronounced when SAD and CKD were performed together. 5/6 nephrectomy led to hypertension, which was higher in SAD+CKD animals. Regarding renal function, the combination of SAD and CKD resulted in reduced renal plasma and blood flow, increased renal vascular resistance and augmented uraemia when compared to CKD animals. Glomerular filtration rate and BPV were negatively correlated in SAD, CKD and SAD+CKD animals. Moreover, SAD+CKD animals presented a higher level of glomerulosclerosis when compared to all other groups. Cardiac and renal hypertrophy, as well as oxidative stress, was also further increased when SAD and CKD were combined. These results show that SAD prior to 5/6 nephrectomy exacerbates renal dysfunction, suggesting that previous augmented BPV should be considered as an important factor to the progression of renal diseases.

    Full Text Available BACKGROUND: Chronic soil-transmitted helminth (STH infections are associated with effects on systemic immune responses that could be caused by alterations in immune homeostasis. To investigate this, we measured the impact in children of STH infections on cytokine responses and gene expression in unstimulated blood. METHODOLOGY/PRINCIPAL FINDINGS: Sixty children were classified as having chronic, light, or no STH infections. Peripheral blood mononuclear cells were cultured in medium for 5 days to measure cytokine accumulation. RNA was isolated from peripheral blood and gene expression analysed using microarrays. Different infection groups were compared for the purpose of analysis: STH infection (combined chronic and light vs. uninfected groups and chronic STH infection (chronic vs. combined light and uninfected groups. The chronic STH infection effect was associated with elevated production of GM-CSF (P=0.007, IL-2 (P=0.03, IL-5 (P=0.01, and IL-10 (P=0.01. Data reduction suggested that chronic infections were primarily associated with an immune phenotype characterized by elevated IL-5 and IL-10, typical of a modified Th2-like response. Chronic STH infections were associated with the up-regulation of genes associated with immune homeostasis (IDO, P=0.03; CCL23, P=0.008, HRK, P=0.005, down-regulation of microRNA hsa-let-7d (P=0.01 and differential regulation of several genes associated with granulocyte-mediated inflammation (IL-8, down-regulated, P=0.0002; RNASE2, up-regulated, P=0.009; RNASE3, up-regulated, p=0.03. CONCLUSIONS/SIGNIFICANCE: Chronic STH infections were associated with a cytokine response indicative of a modified Th2 response. There was evidence that STH infections were associated with a pattern of gene expression suggestive of the induction of homeostatic mechanisms, the differential expression of several inflammatory genes and the down-regulation of microRNA has-let-7d.

    Hypovitaminosis D occurs early in the course of chronic kidney disease (CKD), and its association with cardiovascular morbidity and mortality is well known. In this study, we aimed to evaluate whether the degree of hypovitaminosis D may differently affect blood pressure (BP) and coronary artery calcification (CAC) in nondialyzed CKD patients. This study included 80 CKD patients with a creatinine clearance between 15 and 60 ml/min/1.73 m(2) and serum 25 hydroxivitamin D [25(OH)D] level hypovitaminosis D, were defined according to the median 25(OH)D value. Patients with severe hypovitaminosis D [25(OH)D hypovitaminosis D [25(OH)D >17.2 ng/ml; M-group]. No differences were found between the S and M-group in terms of diastolic BP and the presence of coronary calcification. In the multiple linear regression analysis, severe hypovitaminosis D was a predictor of 24-h, daytime and nighttime BP after controlling for a number of confounders. The severity of hypovitaminosis D was associated with increased BP in nondialyzed CKD patients. The degree of hypovitaminosis D was not related to CAC, which was equally elevated in both the severe and mild hypovitaminosis D groups.

    Rheumatoid arthritis (RA) is characterized by chronic synovial inflammation, which can cause progressive joint damage and disability. Diffuse optical spectroscopy (DOS) and imaging have the potential to become potent monitoring tools for RA. We devised a method that combined time-resolved DOS and tracer kinetics modeling to rapidly and reliably quantify blood flow in the joint. Preliminary results obtained from two animals show that the technique can detect joint inflammation as early as 5 days after onset.

    A prospective analysis of 60 patients with gout was undertaken to evaluate the radiographic spectrum of gouty arthritis in patients treated in the era of hypouricemic therapy. Twenty-two of these patients were clinically tophaceous; 36 were considered to have radiographic findings diagnostic of gouty arthritis by strict radiographic criteria. Up to 24% of the patients denied symptoms in joints with radiographic changes of gout; 42% with no evidence of tophi on clinical examination had radiographic changes characteristic of gout. Radiographic assessment can be extremely helpful in the management of gout by documenting the degree and extent of bony involvement, particularly in patients with limited symptoms or without clinical tophi.

    Full Text Available Quinalphos (QP is commonly used for pest control in the agricultural fields surrounding freshwater reservoirs. This study was conducted to evaluate the chronic toxicity of this pesticide on blood parameters and some organs of silver barb, Barbonymus gonionotus. Fish were exposed to two sublethal concentrations, 0.47 ppm and 0.94 ppm, of QP for a period of 28 days. All the blood parameters (red blood cell, hematocrit, and hemoglobin and blood glucose except for white blood cells decreased with increasing concentration of toxicant and become significantly lower (p<0.05 at higher concentration when compared with control. The derived hematological indices of mean corpuscular volume, mean corpuscular hemoglobin, and mean corpuscular hemoglobin concentration were equally altered compared to control. Histoarchitectural changes of liver and kidney were observed after exposure to the QP. Hypertrophy of hepatocytes, mild to severe necrosis, ruptured central vein, and vacuolation were observed in the liver of treated groups. Highly degenerated kidney tubules and hematopoietic tissue, degeneration of renal corpuscle, vacuolization, and necrosis were evident in the kidney of treated groups. In conclusion, chronic exposure to QP at sublethal concentrations induced hematological and histological alterations in silver barb and offers a simple tool to evaluate toxicity derived alterations.

    Chronic arthritis is very common and is associated with a variety of systemic diseases whereas hemophilic arthropathy is one of the most common clinical manifestations of hemophilia, mainly of hemophilia type A. All of these polyarticular diseases are associated with progressive pain and increasing lack of mobility. Therapy is based on conservative treatment such as medication with non-steroidal anti-inflammatory drugs, selective therapy strategies such as intraarticular injections of e.g. radioactive substances (radiosynoviorthesis) or surgical interventions. However, in some cases, the disease does not respond to one of these treatment options or cannot be continued due to important side-effects. Systemic application of radioisotopes like {sup 186}Re HEDP has been successfully administered for pain palliation of osseous metastases. Today, only few data exist for systemic therapy with {sup 186}Re HEDP in patients suffering from benign polyarticular disease. In a prospective study with patients suffering from chronic arthritis a single systemic application of {sup 186}Re HEDP led to a reduction of disease activity in six of eight and to a reduction of the number of painful or swollen joints in five of eight included patients. In a further prospective study with 12 patients with hemophilic arthropathy, 19 of 36 (52.7%) most painful joints could be successfully treated with one systemic {sup 186}Re HEDP therapy. Furthermore, a reduction of global pain could be observed in those patients. However, further randomized studies with larger study populations are necessary in order to confirm this promising results. (orig.)

    Vasodilators are used with caution in patients with chronic obstructive pulmonary disease (COPD). We have developed a device for percutaneous arteriovenous shunt creation in the iliac region to increase cardiac output and oxygen delivery for patients with COPD. Although this device does not cause significant blood pressure changes in normotensive patients with COPD, we hypothesized that arteriovenous shunt creation might cause vasodilator effects in hypertensive patients because of a reduction in vascular resistance.

    Human toxocariasis is a parasitic zoonosis mainly caused by Toxocara canis or Toxocara cati and is acquired by ingestion of the parasite's embryonated eggs. Arthralgia and/or arthritis were reported in up to 17% of the cases, generally with acute duration (less than 6 weeks). However, to our knowledge, chronic polyarthritis, as the isolated presentation of Toxocara infection, was not reported. One of the 5809 patients that was followed up at our service (0.017%) had chronic polyarthritis as the single manifestation of toxocariasis and was described herein. A 3-year-old girl was referred to our service with severe painful chronic polyarthritis for a period longer than 10 weeks and morning stiffness of 30min. Dog contact exposure history in the recreational areas of neighborhood was reported. Her exams showed high levels of eosinophils in peripheral blood (29%), bone marrow aspirate revealed marked eosinophilia (32%) and Toxocara enzyme-linked immunosorbent assay (Elisa) was positive (1:1280). She was treated with paracetamol (40mg/kg/day) and thiabendazole (25mg/kg/day) for 10 days, and all manifestations reduced. After eight months of follow-up, she was on clinical and laboratorial remission. In conclusion, we described a case of chronic polyarthritis, as isolated manifestation of toxocariasis, mimicking juvenile idiopathic arthritis and leukemia. Importantly, this zoonosis should be considered in patients with arthritis and eosinophilia.

    Hypertension, as in adults, is a frequent complication found in children with chronic kidney disease (CKD). Indeed, hypertension has now become one of the most prevalent chronic diseases of childhood. The most recent data available (2003) indicate that at least 38% of children with CKD in the United States are receiving antihypertensive therapy. Only recently has it been shown in children that hypertension, traditionally considered a marker for disease severity in children, is additionally a significant and independent risk factor for accelerated deterioration of kidney function and progression of CKD and a significant risk factor for cardiovascular disease. The following review outlines the differences and similarities of childhood versus adult hypertension with respect to measurement, diagnosis, treatment, and consequence in CKD. The definition of hypertension changes continually as a child grows with or without CKD. Despite numerous guidelines, the diagnosis of childhood hypertension continues to be based on epidemiologic data rather than evidence. For children, the current definition includes 2 categories: high normal, which is blood pressure (BP) between the 90th and 95th percentile, and hypertensive, which is BP above the 95th percentile. The evaluation of all hypertensive children should include a complete assessment of end-organ damage, including eyes, cardiovascular system (including blood vessels), kidneys, and nervous system. For children with CKD and end-stage renal disease (ESRD), a high percentage have left ventricular hypertrophy (LVH). The finding of end-organ damage or comorbidity (CKD, diabetes) in any child is an absolute indication for immediate pharmacologic therapy, whereas the presence of hypertension above the 95th percentile in children without CKD warrants initial intervention such as life style modification. The guidelines for measurement of BP in children with CKD are similar to those in children without CKD and include casual BP

    Full Text Available The goal is to study the cerebral blood flow and psychometric characteristics in veterans of Afghanistan with early forms of chronic brain ischemia. Material and Methods. The study included 74 veterans of the Afghan war aged from 45 to 55 years: group 1, 28 people with NPNKM; Group 2-28 patients with circulatory encephalopathy stage 1; group 3-18 healthy persons. Doppler examination of cerebral vessels was carried out on the unit «Smart-lite». Reactive and personal anxiety of patients was assessed using the scale of Spielberger, evaluation of the quality of life through the test SAN. Determining the level of neuroticism and psychoticism was conducted by the scale of neuroticism and psy-choticism. Results: The study of cerebral blood flow in the Afghan war veterans showed signs of insolvency of carotid and carotid-basilar anastomoses, hypoperfusion phenomenon with the depletion of autoregulation, violation of the outflow of venous blood at the level of the microvasculature, accompanied by cerebral arteries spasm. More than 40% of patients with early forms of chronic brain ischemia had high personal anxiety, low levels of well-being and activity, with maximum expression of dyscirculatory hypoxia. Conclusion. Readaptation of veterans of Afghanistan is accompanied by the changes in psychometric performance and the formation of the earliest forms of brain chronic ischemia associated with inadequate hemodynamics providing increased functional activity of the brain and the inefficiency of compensatory-adaptive reactions.

    A pathogenic role for Streptococcus (S) pyogenes infections in chronic plaque psoriasis is suspected but poorly defined. We separated cellular and supernatant proteins from S. pyogenes cultures by high-resolution two-dimensional gel electrophoresis, and used immunoblotting to demonstrate the diversity of serum or plasma IgGs that react with elements of the proteome of this bacterium. We have shown that a substantial proportion of IgG-reactive proteins from cultured S. pyogenes are secreted. The total secreted protein fraction, including diverse IgG-binding elements, was subsequently used in an ELISA to measure blood titers of reactive IgG. This ELISA showed that blood samples from patients with chronic plaque psoriasis contained significantly higher titers of reactive IgG than samples from age- and sex-matched healthy controls (P=0.0009). In contrast, neither a standard assay measuring antistreptolysin O titers nor ELISAs measuring titers of IgG reactive with protein fractions from Staphylococcus aureus and Staphylococcus epidermidis, were able to distinguish between blood samples from the two groups. These findings justify the hypothesis that S. pyogenes infections are more important in the pathogenesis of chronic plaque psoriasis than has previously been recognized, and indicate the need for further controlled therapeutic trials of antibacterial measures in this common skin disease.

  13. Chronic kidney disease predicts impaired membrane microviscosity of red blood cells in hypertensive and normotensive subjects.

    Tsuda, Kazushi

    2013-01-01

    Current evidence indicates that abnormalities in physical properties of the cell membranes may be strongly linked to hypertension and other circulatory disorders. Recent studies have shown that chronic kidney disease (CKD) might be a risk factor for cardiovascular and cerebrovascular outcomes. The purpose of the present study was to examine the possible relationship between kidney function and membrane fluidity (a reciprocal value of membrane microviscosity) of red blood cells (RBCs) in hypertensive and normotensive subjects using an electron spin resonance (ESR) and spin-labeling method. The order parameter (S) for the ESR spin-label agent (5-nitroxide stearate) in RBC membranes was significantly higher in hypertensive subjects than in normotensive subjects, indicating that membrane fluidity was decreased in hypertension. The order parameter (S) of RBCs was inversely correlated with estimated glomerular filtration rate (eGFR), suggesting that a decreased eGFR value might be associated with reduced membrane fluidity of RBCs. Multivariate regression analysis also demonstrated that, after adjustment for general risk factors, eGFR might be a significant predictor of membrane fluidity of RBCs. The reduced levels of both membrane fluidity of RBCs and eGFR were associated with increased plasma 8-iso-prostaglandin F2α (an index of oxidative stress) and decreased plasma nitric oxide (NO)-metabolites, suggesting that kidney function could be a determinant of membrane microviscosity of RBCs, at least in part, via oxidative stress- and NO-dependent mechanisms. The ESR study suggests that CKD might have a close correlation with impaired rheologic behavior of RBCs and microcirculatory disorders in hypertensive subjects.

    2015-11-01

    Rheumatic diseases, such as rheumatoid and psoriatic arthritis are systemic inflammatory conditions characterized by a chronic form of arthritis, often leading to irreversible joint damage. Early treatment for patients with rheumatic diseases is required to reduce or prevent joint injury. However, early diagnosis can be difficult and currently it is not possible to predict which individual patient will develop progressive erosive disease or who may benefit from a specific treatment according to their clinical features at presentation. Biomarkers are therefore required to enable earlier diagnosis and predict prognosis in both rheumatoid arthritis and psoriatic arthritis. In this review we will examine the evidence and current status of established and experimental biomarkers in rheumatoid and psoriatic arthritis for three important purposes; disease diagnosis, prognosis and prediction of response to therapy.

    Synovial membranes in patients with rheumatoid arthritis as well as other types of chronic destructive inflammatory arthritis contain infiltrates of activated T lymphocytes that probably contribute to the pathogenesis of the disease. In an effort to elucidate the nature of these infiltrates, interleukin 2 (IL-2)-responsive T lymphocytes were grown out of synovial fragments from 14 patients undergoing surgery for advanced destructive inflammatory joint disease. Eleven of the samples examined were from patients with classical rheumatoid arthritis, while three others were obtained from individuals with clinical osteoarthritis. Southern blot analysis of T-cell receptor (TCR) ..beta..-chain genes in 13 of 14 cultures showed distinct rearrangements, indicating that each culture was characterized by the predominance of a limited number of clones. T-cell populations from peripheral blood stimulated with a variety of activators and expanded with IL-2 did not demonstrate evidence of similar clonality in long-term culture. These results suggest that a limited number of activated T-cell clones predominate at the site of tissue injury in rheumatoid synovial membranes as well as in other types of destructive inflammatory joint disease. Further characterization of these T-cell clones may aid our understanding of the pathogenesis of these rheumatic disorders.

    Background: Progression of Chronic kidney disease (CKD) may result from tissue hypoxia induced by small artery structural narrowing, with increased renal vascular resistance (RVR) and impaired blood supply. We investigated whether vasodilating therapy (VT) is superior to non-vasodilating therapy...... (nonVT) for improvement of RVR, tissue oxygenation, and preservation of kidney function.

    Full Text Available Juvenile Idiopathic Arthritis (JIA is the most chronic musculoskeletal disease of pediatric population. The chronic course of disease has a great impact on oral health. Temporomandibular joint is involved in JIA causing limited mouth opening with progressive open bite, retrognathia, microgenia and bird like appearance. Joints of upper and lower extremities are also involved. Effect on upper limb function leads to difficulty with fine motor movements required for brushing and flossing. This increases incidence of caries and periodontal disease in children. The cause of JIA is still poorly understood and none of the available drugs for JIA can cure the disease. However, prognosis has improved as a result of progress in disease classification and management. The dental practitioner should be familiar with the symptoms and oral manifestations of JIA to help manage as multidisciplinary management is essential.

    2014-06-01

    Full Text Available Microcrystals are responsible for some of the most common and complex arthropathies which are often accompanied by intense, severe pain and inflammatory reactions. The main pathogens are crystals of monosodium urate (MSU, responsible for the gout, calcium pyrophosphate (CPP, which deposits also in various clinical forms of arthopathies, and basic calcium phosphate associated with osteoarthritis. In this context, the microcrystal arthritis is characterized by multiple, acute attacks followed by chronic pain, disability, impaired quality of life, and increased mortality. Given their chronic nature, they represent an ever more urgent public health problem. MSU and CPP crystals are also able to activate nociceptors. The pain in mycrocrystalline arthritis (MCA is an expression of the inflammatory process. In the course of these diseases there is an abundant release of inflammatory molecules, including prostaglandins 2 and kinins. Interleukin-1 represents the most important cytokine released during the crystal-induced inflammatory process. Therefore, clinically, pain is the most important component of MCA, which lead to functional impairment and disability in a large proportion of the population. It is fundamental to diagnose these diseases as early as possible, and to this aim, to identify appropriate and specific targets for a timely therapeutic intervention.

    Full Text Available Juvenile rheumatoid arthritis (JRA is the most common rheumatic condition in children. JRA is defined as persistent arthritis in 1 or more joints for at least 6 weeks, with the onset before age 16 years. The etiology of JRA is unknown. Antigen activated CD4+ T cell stimulate monocytes, macrophages, and synovial fibroblasts to produce the cytokines Interleukin-1 (IL-1, IL-6, and tumor necrosis factor ? (TNF-? and to secrete matrix metalloproteinases, which lead to chronic inflammation due to infiltration of inflammatory cell, angiogenesis, destruction of cartilage and bone with pannus formation. The 3 major subtypes of JRA are based on the symptoms at disease onset and are designated systemic onset, pauciarticular onset, and polyarticular onset. For all patients, the goals of therapy are to decrease chronic joint pain and suppress the inflammatory process. Poor prognostic have been observed in patients with polyarticular onset, rheumatoid factor, persistent morning stiffness, tenosynovitis, involvement of the small joints, rapid appearance of erosions, active late onset childhood, subcutaneous nodules, or antinuclear antibody.

  8. Glucose kinetics in the collagen-induced arthritis model: an all-in-one model to assess both efficacy and metabolic side effects of glucocorticoids.

    Directory of Open Access Journals (Sweden)

    Erik J M Toonen

    Full Text Available Prednisolone and other glucocorticoids (GCs are potent anti-inflammatory drugs, but chronic use is hampered by metabolic side effects. Therefore, there is an urgent medical need for improved GCs that are as effective as classical GCs but have a better safety profile. A well-established model to assess anti-inflammatory efficacy is the chronic collagen-induced arthritis (CIA model in mice, a model with features resembling rheumatoid arthritis. Models to quantify undesired effects of glucocorticoids on glucose kinetics are less well-established. Recently, we have described a model to quantify basal blood glucose kinetics using stably-labeled glucose. In the present study, we have integrated this blood glucose kinetic model in the CIA model to enable quantification of both efficacy and adverse effects in one animal model. Arthritis scores were decreased after treatment with prednisolone, confirming the anti-inflammatory properties of GCs. Both inflammation and prednisolone induced insulin resistance as insulin secretion was strongly increased whereas blood glucose concentrations and hepatic glucose production were only slightly decreased. This insulin resistance did not directly resulted in hyperglycemia, indicating a highly adaptive compensatory mechanism in these mice. In conclusion, this 'all-in-one' model allows for studying effects of (novel GC compounds on the development of arthritis and glucose kinetics in a single animal. This integrative model provides a valuable tool for investigating (drug-induced metabolic dysregulation in an inflammatory setting.

    Of 511 cases of brucellosis studied between December 1983 and February 1986, four (0.8%) had sternoclavicular (STCL) arthritis. Two were male and two female, and only one was younger than 50 years old. All four cases had significantly high specific IgG antibody titres (1 of 1280), measured by the indirect immunofluorescent (IIF) test, and two had Brucella melitensis isolated from their blood. In two cases, STCL arthritis was the presenting problem, and it was associated in one with ankle arthritis, hepatitis, renal impairment, orogenital ulcers and a haematological picture of myelodysplasia; in the other it was a relapsing STCL arthritis. In the remaining two cases, STCL arthritis was part of an extensive osteoarticular disease, which was associated in one with cachexia, liver cirrhosis, heart failure and prostatitis with urine retention, and in the other with severe thrombocytopenia. Excellent results were obtained from six to eight weeks' therapy with streptomycin, rifampicin and cotrimoxazole or tetracycline.

    Identifying neovascularity (angiogenesis) as an early feature of inflammatory arthritis can help in early accurate diagnosis and treatment monitoring of this disease. Photoacoustic tomography (PAT) is a hybrid imaging modality which relies on intrinsic differences in the optical absorption among the tissues being imaged. Since blood has highly absorbing chromophores including both oxygenated and deoxygenated hemoglobin, PAT holds potential in identifying early angiogenesis associated with inflammatory joint diseases. PAT is used to identify changes in the development of inflammatory arthritis in a rat model. Imaging at two different wavelengths, 1064 nm and 532 nm, on rats revealed that there is a significant signal enhancement in the ankle joints of the arthritis affected rats when compared to the normal control group. Histology images obtained from both the normal and the arthritis affected rats correlated well with the PAT findings. Results support the fact that the emerging PAT could become a new tool for clinical management of inflammatory arthritis.

    1. The oxygen consumption of blood of normal individuals, when the hemoglobin is saturated with oxygen, is practically zero within the limits of experimental error of the microspirometer used. 2. The oxygen consumed in a microspirometer by the blood of patients with chronic myelogenous leucemia with a high white blood cell count, and of one with leucocytosis from sepsis, was proportional to the number of adult polymorphonuclear neutrophils in the blood. 3. No correlation could be made between the rate of oxygen absorption and the total number of white blood cells in the blood, or the total number of immature cells, or the number of red blood cells, or the amount of oxyhemoglobin. 4. The blood of patients with chronic myelogenous leucemia continued to use oxygen in the microspirometer longer than that of normal individuals, and the hemoglobin, in the leucemic bloods, became desaturated even though exposed to air. 5. In blood in which the bulk. of the cells were immature and the mature cells few, the oxygen consumption was lower than in blood in which the mature cells predominated. The rate of oxygen consumption of the immature cells was relatively low as compared to the mature. 6. The slower rate of oxygen absorption by the immature leucocytes in chronic myelogenous leucemia as compared to the mature cells, places them, in accord with Warburg's reports, in the class of the malignant tissues in this respect rather than in the group of young or embryonic cells.

    Epstein-Barr virus-induced gene 3 (Ebi3) and the p35 subunit of IL-12 have been reported to form a heterodimeric cytokine, named IL-35, in human and mouse. In mice, IL-35 has been shown to be constitutively expressed by CD4(+)CD25(+)Foxp3(+) regulatory T cells (Tregs) and suggested to contribute to their suppressive activity. However, human CD4(+)CD25(+)Foxp3(+) Tregs do not constitutively express detectable amounts of IL-35 in both mRNA and protein levels. Circulating CD4(+)CD25(+) Treg frequency of chronic Hepatitis B patients significantly correlates with serum viral load. In this study, we investigated whether IL-35 expression could be detected in CD4(+) T cells from peripheral blood of chronic Hepatitis B patients. Using both RT-PCR and immunoprecipitation plus Western blot analysis, we demonstrated that IL-35 expression could be detected in the CD4(+) T cells from peripheral blood of Chronic Hepatitis B patients.

    Stroke is a life threatening disease leading to long-term disability in stroke survivors. Cerebral functional insufficiency in chronic stroke might be due to pathological changes in brain areas remote from initial ischemic lesion, i.e. diaschisis. Previously, we showed that the damaged blood-brain barrier (BBB) was implicated in subacute diaschisis. The present study investigated BBB competence in chronic diaschisis using a transient middle cerebral artery occlusion (tMCAO) rat model. Our results demonstrated significant BBB damage mostly in the ipsilateral striatum and motor cortex in rats at 30 days after tMCAO. The BBB alterations were also determined in the contralateral hemisphere via ultrastructural and immunohistochemical analyses. Major BBB pathological changes in contralateral remote striatum and motor cortex areas included: (1) vacuolated endothelial cells containing large autophagosomes, (2) degenerated pericytes displaying mitochondria with cristae disruption, (3) degenerated astrocytes and perivascular edema, (4) Evans Blue extravasation, and (5) appearance of parenchymal astrogliosis. Importantly, discrete analyses of striatal and motor cortex areas revealed significantly higher autophagosome accumulation in capillaries of ventral striatum and astrogliosis in dorsal striatum in both cerebral hemispheres. These widespread microvascular alterations in ipsilateral and contralateral brain hemispheres suggest persistent and/or continued BBB damage in chronic ischemia. The pathological changes in remote brain areas likely indicate chronic ischemic diaschisis, which should be considered in the development of treatment strategies for stroke. PMID:24610730

    Full Text Available Abstract Background Genomic profiling of peripheral blood reveals altered immunity in chronic fatigue syndrome (CFS however interpretation remains challenging without immune demographic context. The object of this work is to identify modulation of specific immune functional components and restructuring of co-expression networks characteristic of CFS using the quantitative genomics of peripheral blood. Methods Gene sets were constructed a priori for CD4+ T cells, CD8+ T cells, CD19+ B cells, CD14+ monocytes and CD16+ neutrophils from published data. A group of 111 women were classified using empiric case definition (U.S. Centers for Disease Control and Prevention and unsupervised latent cluster analysis (LCA. Microarray profiles of peripheral blood were analyzed for expression of leukocyte-specific gene sets and characteristic changes in co-expression identified from topological evaluation of linear correlation networks. Results Median expression for a set of 6 genes preferentially up-regulated in CD19+ B cells was significantly lower in CFS (p = 0.01 due mainly to PTPRK and TSPAN3 expression. Although no other gene set was differentially expressed at p Conclusion Dissection of blood microarray profiles points to B cell dysfunction with coordinated immune activation supporting persistent inflammation and antibody-mediated NK cell modulation of T cell activity. This has clinical implications as the CD19+ genes identified could provide robust and biologically meaningful basis for the early detection and unambiguous phenotyping of CFS.

    Background: The relationship between diabetes and periodontitis has been studied for more than 50 years and is generally agreed that the periodontal disease is more prevalent in diabetic patients compared to nondiabetics. Vascular changes like increased thickness of basement membrane in small vessels has been reported in diabetic patients, but the quantity of blood vessels in gingiva of diabetic patients has not been discussed much. The aim of this study was to compare the number of blood vessels in gingiva between chronic periodontitis (CP) patients, CP with diabetes (type 2), and normal healthy gingiva. Materials and Methods: The study included 75 patients, divided into three groups of 25 patients each-Group I with healthy periodontium (HP), Group II with CP, and Group III with CP with diabetes mellitus (CPDM). Gingival biopsies were obtained from the subjects undergoing crown lengthening procedure for Group I, and in patients with CP and in CPDM biopsies were collected from teeth undergoing extraction. Sections were prepared for immune histochemical staining with CD34. Results: Difference was observed in the average number of blood vessels when compared between HP, CP, and CPDM groups. Statistical significant difference was observed when the HP and CP groups and HP and CPDM groups were compared. Conclusion: The results of the study indicated that the number of blood vessels in gingival connective tissue is significantly higher in CP and CPDM patients. PMID:26015666

    Metabolic acidosis has profound effects on vascular tone. This study investigated the in vivo effects of acute metabolic acidosis (AMA) and chronic metabolic acidosis (CMA) on hemodynamic parameters and endothelial function. CMA was induced by ad libitum intake of 1% NH4Cl for 7 days, and AMA was induced by a 3-h infusion of 6 M NH4Cl (1 mL/kg, diluted 1:10). Phenylephrine (Phe) and acetylcholine (Ach) dose-response curves were performed by venous infusion with simultaneous venous and arterial blood pressure monitoring. Plasma nitrite/nitrate (NOx) was measured by chemiluminescence. The CMA group had a blood pH of 7.15±0.03, which was associated with reduced bicarbonate (13.8±0.98 mmol/L) and no change in the partial pressure of arterial carbon dioxide (PaCO2). The AMA group had a pH of 7.20±0.01, which was associated with decreases in bicarbonate (10.8±0.54 mmol/L) and PaCO2 (47.8±2.54 to 23.2±0.74 mmHg) and accompanied by hyperventilation. Phe or ACh infusion did not affect arterial or venous blood pressure in the CMA group. However, the ACh infusion decreased the arterial blood pressure (ΔBP: -28.0±2.35 mm Hg [AMA] to -4.5±2.89 mmHg [control]) in the AMA group. Plasma NOx was normal after CMA but increased after AMA (25.3±0.88 to 31.3±0.54 μM). These results indicate that AMA, but not CMA, potentiated the Ach-induced decrease in blood pressure and led to an increase in plasma NOx, reinforcing the effect of pH imbalance on vascular tone and blood pressure control.

    Rheumatoid arthritis (RA) is a systemic chronic inflammatory disease characterized by extensive synovitis resulting in erosions of articular cartilage and marginal bone with joint destruction. The lack of immunological tolerance in RA represents the first step toward the development of autoimmunity. Susceptible individuals, under the influence of environmental factors, such as tobacco smoke, and silica exposure, develop autoimmune phenomena that result in the presence of autoantibodies. HLA and non-HLA haplotypes play a major role in determining the development of specific autoantibodies differentiating anti-citrullinated antibodies (ACPA)-positive and negative RA patients. Rheumatoid factor (RF) and ACPA are the serological markers for RA, and during the preclinical immunological phase, autoantibody titers increase with a progressive spread of ACPA antigens repertoire. The presence of ACPA represents an independent risk factor for developing RA in patients with undifferentiated arthritis or arthralgia. Moreover, anti-CarP antibodies have been identified in patients with RA as well as in individuals before the onset of clinical symptoms of RA. Several autoantibodies mainly targeting post-translational modified proteins have been investigated as possible biomarkers to improve the early diagnosis, prognosis and response to therapy in RA patients. Psoriatic arthritis (PsA) is distinguished from RA by infrequent positivity for RF and ACPA, together with other distinctive clinical features. Actually, specific autoantibodies have not been described. Recently, anti-CarP antibodies have been reported in sera from PsA patients with active disease. Further investigations on autoantibodies showing high specificity and sensibility as well as relevant correlation with disease severity, progression, and response to therapy are awaited in inflammatory arthritides.

    Full Text Available Vasculitis is a heterogeneous group of disorders characterized by the presence of necrotic inflammatory phenomena and destruction of blood vessels. Vasculitis is classified as primary (idiopathic or secondary to infections, connective tissue diseases and drugs but can also be considered as a paraneoplastic phenomenon. Evidence shows that the increasing use of biological agents results in a growing number of reports of autoimmune diseases induced by these therapies. An inflammatory articular chronic disease such as rheumatoid arthritis may be complicated by extra-articular manifestations, such as cutaneous or systemic vasculitis. Herewith, we describe the case of a great vessels arteritis in a patient affected by rheumatoid arthritis in therapy with an anti-TNF agent (etanercept.

    Full Text Available CONTEXT: The exact mechanism involved in changes in blood pressure and peripheral vascular resistance during pregnancy is unknown. OBJECTIVE:To evaluate the importance of endothelium-derivated relaxing factor (EDRF and its main component, nitric oxide, in blood pressure and vascular reactivity in pregnant rats. DESIGN: Clinical trial in experimentation animals. SETTING: University laboratory of Pharmacology. SAMPLE: Female Wistar rats with normal blood pressure, weight (152 to 227 grams and age (90 to 116 days. INTERVENTION: The rats were divided in to four groups: pregnant rats treated with L-NAME (13 rats; pregnant control rats (8 rats; virgin rats treated with L-NAME (10 rats; virgin control rats (12 rats. The vascular preparations and caudal blood pressure were obtained at the end of pregnancy, or after the administration of L-NAME in virgin rats. MAIN MEASUREMENTS: The caudal blood pressure and the vascular response to acetylcholine in pre-contracted aortic rings, both with and without endothelium, and the effect of nitric oxide inhibition, Nw-L-nitro-arginine methyl-ester (L-NAME, in pregnant and virgin rats. The L-NAME was administered in the drinking water over a 10-day period. RESULTS: The blood pressure decreased in pregnancy. Aortic rings of pregnant rats were more sensitive to acetylcholine than those of virgin rats. After L-NAME treatment, the blood pressure increased and relaxation was blocked in both groups. The fetal-placental unit weight of the L-NAME group was lower than that of the control group. CONCLUSION: Acetylcholine-induced vasorelaxation sensitivity was greater in pregnant rats and that blood pressure increased after L-NAME administration while the acetylcholine-induced vasorelaxation response was blocked.

  19. T cell migration in rheumatoid arthritis

    Full Text Available Rheumatoid arthritis (RA is an autoimmune disease characterized by chronic inflammation in joints, associated with synovial hyperplasia and with bone and cartilage destruction. Although the primacy of T cell-related events early in the disease continues to be debated, there is strong evidence that autoantigen recognition by specific T cells is crucial to the pathophysiology of rheumatoid synovitis. In addition, T cells are key components of the immune cell infiltrate detected in the joints of RA patients. Initial analysis of the cytokines released into the synovial membrane showed an imbalance, with a predominance of proinflammatory mediators, indicating a deleterious effect of Th1 T cells. There is nonetheless evidence that Th17 cells also play an important role in RA. T cells migrate from the bloodstream to the synovial tissue via their interactions with the endothelial cells that line synovial postcapillary venules. At this stage, selectins, integrins and chemokines have a central role in blood cell invasion of synovial tissue, and therefore in the intensity of the inflammatory response.In this review we will focus on the mechanisms involved in T cell attraction to the joint, the proteins involved in their extravasation from blood vessels, and the signaling pathways activated. Knowledge of these processes will lead to a better understanding of the mechanism by which the systemic immune response causes local joint disorders and will help to provide a molecular basis for therapeutic strategies.

    Objective Cerebral autoregulation (CA) is the mechanism by which constant cerebral blood flow is maintained despite changes in cerebral perfusion pressure.CA can be evaluated by dynamic monitoring of cerebral blood flow velocity (CBFV) with transcranial Doppler sonography (TCD).The present study aimed to explore CA in chronic anxiety.Methods Subjects with Hamilton anxiety scale scores ≥14 were enrolled and the dynamic changes of CBFV in response to an orthostatic challenge were investigated using TCD.Results In both the anxious and the healthy subjects,the mean CBFV was significantly lower in the upright position than when supine.However,the CBFV changes from supine to upright differed between the anxious and the healthy groups.Anxious subjects showed more pronounced decreases in CBFV with abrupt standing.Conclusion Our results indicate that cerebrovascular modulation is compromised in chronic anxiety; anxious subjects have some insufficiency in maintaining cerebral perfusion after postural change.Given the fact that anxiety and impaired CA are associated with cardiovascular disease,early ascertainment of compromised cerebrovascular modulation using TCD might suggest interventional therapies in the anxious population,and improve the primary prevention of cardiovascular disease.

    A method for the treatment of chronic sensorineural hearing loss (CSNHL) is proposed that includes administration of trental followed by intravenous laser irradiation of blood (IVLBI). The study included 81 patients at the age from 20 to more than 60 years presenting with CSNHL. They were allocated to three groups; the patients in group 1 (n=32) were given trental intravenously followed by intravenous laser irradiation of blood, those of group 2 (n=24) were treated with IVLBI alone while patients of group 3 (n=25) received "traditional" treatment. Audiometric examination and rheoencephalography were carried out before and after therapy. The hearing improved to 18-20 dB in group 1, to 10-15 dB in group 2, and to 10 dB in group 3. The improvement of rheoencephalographic characteristics was documented in the patients of all groups but was especially pronounced in group 1. It is concluded that the proposed method significantly increases the efficiency of treatment of chronic sensorineural hearing loss.

    Full Text Available In this study we evaluated the possible protective effects of selenium (Se on hematological and oxidative stress parameters in rats chronically treated with cisplatin (cisPt. Four groups of Wistar albino rats were examined: a control, untreated rats (I, rats treated with Se (II, rats treated with cisPt (III, and rats treated with Se and cisPt (IV. All animals were treated for 5 days successively and killed 24 h after the last treatment. Hematological and oxidative stress parameters were followed in whole blood and red blood cells (RBC. Results showed that the chronic application of Se was followed by a higher number of reticulocytes and platelets, increased lipid peroxidation and GSH content in the RBC. Cisplatin treatment induced depletion of RBC and platelet numbers and an elevation of the superoxide anion, nitrites and glutathione levels. Se and cisPt co-treatment was followed by an elevation of the hematological parameters and the recovery of the glutathione status when compared to the control and cisPt-treated rats.

    Blood-brain barrier (BBB) permeabilizers, such as mannitol, can facilitate peripherally delivered stem cells to exert therapeutic benefits on the stroke brain. Although this BBB permeation-aided stem cell therapy has been demonstrated in the acute stage of stroke, such BBB permeation in the chronic stage of the disease remains to be examined. Adult Sprague-Dawley rats initially received sham surgery or experimental stroke via the 1-h middle cerebral artery occlusion (MCAo) model. At 1 month after the MCAo surgery, stroke animals were randomly assigned to receive human umbilical cord stem cells only (2 million viable cells), mannitol only (1.1 mol/L mannitol at 4°C), combined human umbilical cord stem cells (200,000 viable cells) and mannitol (1.1 mol/L mannitol at 4°C), and vehicle (phosphate-buffered saline) only. Stroke animals that received human umbilical cord blood cells alone or combined human umbilical cord stem cells and mannitol exhibited significantly improved motor performance and significantly better brain cell survival in the peri-infarct area compared to stroke animals that received vehicle or mannitol alone, with mannitol treatment reducing the stem cell dose necessary to afford functional outcomes. Enhanced neurogenesis in the subventricular zone accompanied the combined treatment of human umbilical cord stem cells and mannitol. We showed that BBB permeation facilitates the therapeutic effects of a low dose of peripherally transplanted stem cells to effectively cause functional improvement and increase neurogenesis in chronic stroke.

    The development of novel anti-rheumatic drugs revolutionizes currently therapeutic strategies and diagnostic management of patients with rheumatoid arthritis, facilitating the goal of true remission instead of only symptomatic treatment as in former years. Since early treatment is known to be crucial for the longterm outcome, imaging modalities such as magnetic resonance imaging and high-frequency ultrasonography including Doppler sonography, which allow direct visualization of very early pathologic alterations of synovitis, or even initial destruction, become increasingly important. Besides the established therapy with methotrexate, new drugs such as leflunomide or the use of various combination therapies have been successfully introduced into the therapeutic armamentarium. Especially the introduction of cytokine-antagonists such as TNF-a inhibitors target the aim of remission. In addition, the upcoming therapeutic agents, which influence very effectively the inflammatory and destructive process need also to be integrated into the concert of different therapeutic strategies in the management of patients with rheumatoid arthritis, which includes the mandatory complementary factors such as physiotherapy, ergotherapy and orthopedic surgery.

    The purpose of the study was to examine the value of regular measurements of plasma renin concentration (PRC) in selecting those chronic haemodialysis patients suitable for bilateral nephrectomy to prevent development of uncontrollable hypertension. Regular measurements of arterial blood pressure (BP) and PRC were performed during one year in 31 patients undergoing regular haemodialysis because of end-stage renal disease. Among 18 patients with PRC greater than or equal to 100 micro Goldblatt units per ml plasma (microGU/ml) systolic and/or diastolic hypertension persisted or developed in 12. In contrast, among 13 patients with PRC greater than 100microGU/ml, BP became normal in all but one, who had a slightly increased systolic BP. However, hypertension was mild and easily controlled by conventional therapy in all except one, who probably had an overlying volume-dependent hypertension. Therefore, bilateral nephrectomy was not necessary in any case. The results indicate that hypertension in the majority of chronic haemodialysis patients with high PRC can be adequately controlled without surgical intervention and that regular measurements of PRC have no practical value in forecasting the development of uncontrollable hypertension in chronic haemodialysis patients.

    Rheumatoid arthritis (RA) patients are vulnerable to cardiovascular morbidity and mortality in which atherosclerosis plays a major role. In this study, the lipid profile and fasting blood sugar (FBS) of RA patients receiving a complementary medicine of olive and fig, as add-on therapy for routine disease-modifying antirheumatic drugs (DMARDs) regimen containing low dose methotrexate (MTX), were studied. A randomized controlled clinical trial was designed. Adult RA patients were randomly allocated in two groups receiving routine DMARDs regimen (control group) and routine DMARDs regimen plus the herbal supplementary formulation of olive oil, fig and olive fruits (intervention group). Patients were followed every 4 weeks for total study period of 16 weeks. In addition to demographic and medical history of the patients, the total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglyceride (TG), the atherogenic index of plasma (AIP) defined as log(TG/HDL-C), and the fasting blood sugar (FBS) were determined and recorded. 56 patients (control = 27 and intervention = 29), with mean ± sd age of 50.9 ± 12.3 years completed the study. Average MTX dose received by intervention and control groups were 24.30 ± 18.39 and 17.61 ± 15.53 mg/week, respectively (p = 0.11). Repeated measures analysis of variance (ANOVA) revealed that differences between lipid profile indicators and FBS in the two study groups were not statistically significant (P>0.05). No additional substantial adverse reaction was seen in the study groups. Our findings are more reassuring for patients and their doctors to trust on the safety of the investigated complementary preparation to be used as add-on therapy to manage rheumatoid arthritis.

    Full Text Available Objective. To study different variants of osteolysis in pts with psoriatic arthritis (PA and to reveal their relationship with other clinico-radiological features of joint damage. Material and methods. 370 pts with definite PA having different variants of joint damage were included. Radiological examination of bones and joints (in some cases large picture frame was performed. Morphological evaluation of synovial biopsies was done in 34 pts with PA and 10 pts with rheumatoid arthritis (RA. Results. Different types of osteolysis were revealed in 80 (21,6% pts. Osteolytic variant of joint damage was present in 29 pts. 33 pts had acral, 48 — intra-articular osteolysis and 16 - true bone atrophy. Frequency and intensity of bone resorption were associated with severity of PA. Acral osteolysis correlated with arthritis of distal interphalangeal joints and onychodystrophy. Intra-articular osteolysis was most often present in distal interphalangeal joints of hands and metacarpophalangeal joints (39,6% and 41,7% respectively. Characteristic feature of PA was combination of prominent resorption with formation of bone ankylosis and periosteal reaction. Ankylosis was present in 33,3% of pts with intra-articular osteolysis and in 60% of pts with combination of different osteolysis variants. Systemic reaction of microcirculation in synovial biopsies was most prominent in osteolytic variant: marked thickening of capillary and venule basal membrane with high level of acid phosphatase, increased capillary and precapillary blood flow with stasis features, vascular lymphocyte and macrophage infiltration, productive vasculitis with annular wall thickening, thrombovasculitis and villi deep layer sclerosis. Conclusion. Different variants of osteolysis show bone involvement in PA. Acral and intra- articular osteolysis association with bone ankylosis and periostitis proves their common pathogenetic entity.

    Full Text Available Background: The effect of kind of dialysis solution on the control of blood pressure and adequacy and efficacy of hemodialysis is a most debated and controversial issue.Methods: Twenty six chronic hemodialized patients in Ghaem hemodialysis center, Mashhad, Iran, in winter of the year 2004, enrolled this study for one month. The patients were dialyzed with bicarbonate buffer and were dialyzed in the next month with acetate. The kind of membranes and the dialysis machines were the same in both months. Systolic and diastolic pressures were measured before and after hemodialysis in at least three hemodialysis sessions, and he means recorded. The mean of the body weight were also recorded. In the same sessions of hemodialysis by measuring the urea, before and after hemodialysis, urea reduction ratio (URR, was also calculated. Statistical analysis was done with paired student t test for paired measurement, and independent t test for evaluating the effect of the kind of dialysate buffer on the measured parameters.Results: There were no significant statistical differences between acetate and bicarbonate dialysis solution buffers in the control of diastolic blood pressure. But use of acetate buffer resulted in more significant systolic blood pressure reduction compared with bicarbonate buffer (p=0.045. When adequacy of hemodialysis were compared between two kinds of buffers there were no significant statistical differences between them. When the effect of dialysate sodium concentration in the range utilized in two buffers, was evaluated on the systolic and diastolic pressure reduction, no significant differences, between two types of buffers attributable to the difference between dialysates sodium concentrations were found.Conclusion: Hemodialysis with both, acetate and bicarbonate buffers results in significant reductions in systolic and diastolic blood pressure, weight and urea ratio. Use of acetate buffer is more significantly associated with

Arterial blood gas (ABG analyses have an important role in the assessment and monitoring of the metabolic and oxygen status of patients with acute exacerbation of chronic obstructive pulmonary disease (COPD. Arterial puncture could have a lot of adverse effects, while sampling of venous blood is simpler and is not so invasive. Objective. The aim of this study was to evaluate whether venous blood gas (VBG values of pH, partial pressure of carbon dioxide (PCO2, partial oxygen pressure (PO2, bicarbonate (HCO3, and venous and arterial blood oxygen saturation (SO2 can reliably predict ABG levels in patients with acute exacerbation of COPD. Methods. Forty-seven patients with a prior diagnosis of COPD were included in this prospective study. The patients with acute exacerbation of this disease were examined at the General Hospital EMS Department in Prijepolje. ABG samples were taken immediately after venous sampling, and both were analyzed. Results. The Pearson correlation coefficients between arterial and venous parameters were 0.828, 0.877, 0.599, 0.896 and 0.312 for pH, PCO2, PO2, HCO3 and SO2, respectively. The statistically significant correlation between arterial and venous pH, PCO2 and HCO3, values was found in patients with acute exacerbation of COPD (p<0.001. Conclusion. When we cannot provide arterial blood for analysis, venous values of the pH, Pv,CO2 and HCO3 parameters can be an alternative to their arterial equivalents in the interpretation of the metabolic status in patients with acute exacerbation of COPD, while the values of venous Pv,O2 and Sv,O2 cannot be used as predictors in the assessment of oxygen status of such patients.

    The protozoan Trypanosoma cruzi is the causative agent of Chagas disease, a major public health problem in Latin America. This parasite has a complex population structure comprised by six or seven major evolutionary lineages (discrete typing units or DTUs) TcI-TcVI and TcBat, some of which have apparently resulted from ancient hybridization events. Because of the existence of significant biological differences between these lineages, strain characterization methods have been essential to study T. cruzi in its different vectors and hosts. However, available methods can be laborious and costly, limited in resolution or sensitivity. In this study, a new genotyping strategy by real-time PCR to identify each of the six DTUs in clinical blood samples have been developed and evaluated. Two nuclear (SL-IR and 18S rDNA) and two mitochondrial genes (COII and ND1) were selected to develop original primers. The method was evaluated with eight genomic DNA of T. cruzi populations belonging to the six DTUs, one genomic DNA of Trypanosoma rangeli, and 53 blood samples from individuals with chronic Chagas disease. The assays had an analytical sensitivity of 1-25fg of DNA per reaction tube depending on the DTU analyzed. The selectivity of trials with 20fg/μL of genomic DNA identified each DTU, excluding non-targets DTUs in every test. The method was able to characterize 67.9% of the chronically infected clinical samples with high detection of TcII followed by TcI. With the proposed original genotyping methodology, each DTU was established with high sensitivity after a single real-time PCR assay. This novel protocol reduces carryover contamination, enables detection of each DTU independently and in the future, the quantification of each DTU in clinical blood samples.

    Full Text Available Rheumatoid arthritis (RA is a chronic inflammatory disease caused by both genetic and environmental factors. Smoking has been implicated as one of the most important extrinsic risk factors for its development and severity. Recent developments have shed light on the pathophysiology of RA in smokers, including oxidative stress, inflammation, autoantibody formation and epigenetic changes. The association of smoking and the development of RA have been demonstrated through epidemiologic studies, as well as through in vivo and animal models of RA. With increased use of biological agents in addition to standard disease-modifying antirheumatic drugs (DMARDs, there has been interest in how smoking affects drug response in RA treatment. Recent evidence suggests the response and drug survival in people treated with anti-tumour necrosis factor (anti-TNF therapy is poorer in heavy smokers, and possible immunological mechanisms for this effect are presented in the current paper.

    Rheumatoid arthritis (RA) is a chronic and painful clinical condition that leads to progressive joint damage, disability, deterioration in quality of life, and shortened life expectancy. Even mild inflammation may result in irreversible damage and permanent disability. The clinical course according to symptoms may be either intermittent or progressive in patients with RA. In most patients, the clinical course is progressive, and structural damage develops in the first 2 years. The aim of RA management is to achieve pain relief and prevent joint damage and functional loss. Physiotherapy and rehabilitation applications significantly augment medical therapy by improving the management of RA and reducing handicaps in daily living for patients with RA. In this review, the application of physiotherapy modalities is examined, including the use of cold/heat applications, electrical stimulation, and hydrotherapy. Rehabilitation treatment techniques for patients with RA such as joint protection strategies, massage, exercise, and patient education are also presented.

    The systemic effect of radiation increases in proportionally with the dose and dose rate. Little is known concerning the relationships between harmful effects and accumulated dose, which is derived from continuous low-dose rate radiation exposure. Recent our studies show that low-dose-rate chronic radiation exposure (3.49 mGy/h) causes adverse effects in the testis at a dose of 2 Gy (6 mGy/h). However, the mechanism of the low-dose-rate 2 Gy irradiation induced testicular injury remains unclear. The present results indicate that low-dose rate chronic radiation might affect the BTB permeability, possibly by decreasing levels of ZO-1, Occludin-1, and NPC-2. Furthermore, our results suggest that there is a risk of male infertility through BTB impairment even with low-dose-rate radiation if exposure is continuous.

Long-term prognosis in RA was greatly improved following the introduction of highly effective medications such as methotrexate (MTX. Despite the importance of this drug in RA, 8%–16% of patients must discontinue the treatment because of adverse effects. Last decade, we developed a promising new nanocarrier as a drug-delivery system, lipid-core nanocapsules.Objective: The aim of the investigation reported here was to evaluate if methotrexate-loaded lipid-core nanocapsules (MTX-LNC reduce proinflammatory and T-cell-derived cytokines in activated mononuclear cells derived from RA patients and even in functional MTX-resistant conditions. We also aimed to find out if MTX-LNC would reduce inflammation in experimentally inflammatory arthritis at lower doses than MTX solution.Methods: Formulations were prepared by self-assembling methodology. The adjuvant arthritis was induced in Lewis rats (AIA and the effect on edema formation, TNF-a levels, and interleukin-1 beta levels after treatment was evaluated. Mononuclear cells obtained from the synovial fluid of RA patients during articular infiltration procedures were treated with MTX solution and MTX-LNC. For in vitro experiments

    The opioid tetrapeptides endomorphins (EM)-1 and EM-2 are widely expressed in central nervous system and immune tissues of rats and humans. Their analgesic properties are well characterized but they also have anti-inflammatory properties. EM-1 significantly attenuated the onset of hindpaw inflammation in adjuvant-induced arthritis in rats. Immunohistochemical staining demonstrated the presence of EMs in T cells, macrophages, and fibroblasts in synovial tissues from patients with osteo- or rheumatoid arthritis (RA). In an ex vivo superfusion system, EM-1 potently inhibited the release of proinflammatory cytokines interleukin (IL)-6 and IL-8 from synovial tissues from patients with osteo- or RA. These results demonstrate that EMs are endogenously synthesized within human immune cells and have the potential to act as potent therapeutic agents in the treatment of chronic inflammatory disease. We discuss the clinical potential for EM analogues chemically modified to resist proteolytic degradation and identify modified protease-resistant analogues with enhanced bioactivity.

    Background Medical ozone therapy system was reported to have certain effects on the treatment of severe hepatitis,but its mechanism is not very clear. One of the causes of death of severe hepatitis is complication of renal damage or hepatorenal syndrome. The present study aimed to observe effects of medical ozone therapy system on plasma renin activity (PRA), angiotensin Ⅱ (AⅡ), aldosterone (ALD), renal blood flow and renal function of patients with chronic severe hepatitis and explore mechanisms of medical ozone therapy in the treatment of severe hepatitis.Methods Eighty-five cases with chronic severe hepatitis were randomly divided into ozone therapy group (43 cases)and control group (42 cases). The patients in the ozone therapy group were treated with basic treatments plus ozone therapy system. Basic autohemotherapy was used. One hundred milliliter venous blood was drawn from each patient,and was mixed with 100 ml (35 μg/ml) medical ozone and then was returned the blood to the patient intravenously, once every other day for 20 days. Only the basic treatments were given to the control group. PRA, All, ALD, renal blood flow and damage to renal function of the two groups before treatment and 20 days after treatment were compared. Survival rates were also compared.Results Twenty days after the treatment, in ozone therapy group, PRA was (1.31±0.12) ng·ml-1·h-1, All (111.25±17.35)pg/ml, ALD (251.31 ±22.60) pg/ml, which decreased significantly compared with those before treatment (PRA (2.23±0.13)ng·ml-1 ·h1, AⅡ (155.18±19.13) pg/ml, ALD (405.31±29.88) pg/ml, t=4.67-14.23, P <0.01), also lower than those of control group 20 days after the treatment (PRA (2.02±0.11) ng·ml-1·h-1, All (162.21±15.32) pg/ml, ALD (401.20±35.02) pg/ml,t=4.97-15.61, P <0.01); renal blood flow was (175.15±28.20) ml/min, which increased compared with that before the treatment ((125.68±21.25) ml/min) and was higher than that of control group 20 days after the treatment

    An increased understanding in the pathophysiology of chronic inflammatory diseases, such as rheumatoid arthritis, reveals that the diseased tissue and the increased presence of macrophages and other overexpressed molecules within the tissue can be exploited to enhance the delivery of nanomedicine. Nanomedicine can passively accumulate into chronic inflammatory tissues via the enhanced permeability and retention phenomenon, or be surface conjugated with a ligand to actively bind to receptors overexpressed by cells within chronic inflammatory tissues, leading to increased efficacy and reduced systemic side-effects. This review highlights the research conducted over the past decade on using nanomedicine for potential treatment of rheumatoid arthritis and summarizes some of the major findings and promising opportunities on using nanomedicine to treat this prevalent and chronic disease.

  8. Nutritional considerations in rheumatoid arthritis.

    Touger-Decker, R

    1988-03-01

    Rheumatoid arthritis is a chronic, systemic, inflammatory disorder of unknown etiology. The severity of the disease process adversely affects nutritional status. Articular changes, such as small joint deformities and temporomandibular joint syndrome, alter the ability to self-feed. The inflammatory process may increase metabolic rate. Ingestion, digestion, absorption, and excretion may be compromised by secondary manifestations of the disease. Comprehensive nutrition assessment incorporates evaluation of disease and treatment-specific factors, along with the usual assessment parameters. Abnormal values for certain assessment parameters do not necessarily reflect nutritional status. Treatment methods, including medications, may have an impact on nutritional status, assessment tools, and self-feeding. Nutrition management goals focus on identification and implementation of feeding strategies. Evaluation of the ability to feed oneself includes consideration of functional status, secondary manifestations, and medical treatment. Multiple feeding modalities may be required. Oral supplements, tube feedings, and parenteral nutrition may be employed to meet the nutrition needs of the individual with rheumatoid arthritis.

    Full Text Available Rheumatoid arthritis is a systemic autoimmune disease, mainly poli-artycular, among wide-spread chronic inflammatory diseases, that cause pain, functional limitation, damage and joints deformations, and disability. It is characterized by turns of active inflammation and remission phases. Inflammation degree and persistence are associated to a bad functional prognosis and progressive joint disability. These patients management require a continuous valuation of inflammatory activity index of disease both therapeutic management and to prevent disablement process. We focus on many valuation index of joint disability and functional damage. Very important are both the scales of auto-values concerning the pain and the joint swelling and clinical data get by physician to valuate activity index of disease as defined by DAS28. Significant data come by health-related quality of life, disability and by AIMS2 (Arthritis Impact Measurement Scale.

    Pulmonary hypertension (PH) has emerged as a major complication of several hematologic disorders, including hemoglobinopathies, red cell membrane disorders, chronic myeloproliferative disorders, and splenectomy. With the exception of sickle cell disease, there are a limited number of studies systematically evaluating the prevalence of PH using the gold standard right heart catheterization in these disorders. The cause of the PH in patients with hematologic disorders is multifactorial, and a thorough diagnostic evaluation is essential. More importantly, there are virtually no high-quality data on the safety and efficacy of PH-targeted therapy in this patient population.

    This paper reports the first successful chronic monitoring (for 30 days) of blood pressure, heart rate, EEG, and physical activity in a freely moving bird, following (described) implantation of a commercially available (Data Sciences International) radiotelemetry device in a 1.6-kg broiler chicken. The tip of the device's pressure sensing catheter was introduced into the descending aorta via a leg (ischiadic) artery and, although the catheter was tied in place, circulation in the leg was maintained and leg function was not impaired. EEG was recorded from the device's paired sensing electrodes positioned on the surface of the telencephalon. Physiological and activity data collected by the radiotelemetry system over 2 complete 24-h periods, 1 and 4 weeks after implantation of the device, were analyzed with the system's own (Dataquest LabPRO) analysis software. The results presented are discussed mainly in terms of variation between light and dark periods.

Twenty-eight women were allocated into a control group (n=11, mean ±SEM: age, 43.5 ±1.5 yr; body mass, 66.1 ±3.1 kg; height, 160.6 ±1.5 cm and a vibration group (n=17, mean ±SEM: age, 44.0 ±1.0 yr; body mass, 67.1 ±2.2 kg; height, 162.5 ±1.5 cm. After baseline assessments, participants of the experimental group performed WBV training 3 times/week for 8 weeks. Before and after the chronic WBV exercise, the participants of the vibration group performed one session of acute WBV exercise. Blood chemistry measurements (hematology, creatine kinase, lactate dehydrogenase, aspartate aminotransferase, alanine aminotransferase, C-reactive protein, glucose, insulin, triacylglycerols, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, apolipoprotein A1, apolipoprotein B and lipoprotein, thiobarbituric-acid reactive substances, protein carbonyls, total antioxidant capacity, uric acid, albumin and bilirubin were assessed pre-exercise and post-exercise at the first and eighth week of WBV exercise in both control and vibration groups. The results failed to support any effect of both acute and chronic WBV exercise on biochemical health-related parameters. However, it seems that WBV exercise is a safe way of training without a negative impact on muscle and liver functionality.

    Full Text Available Abstract Juvenile arthritis comprises a variety of chronic inflammatory diseases causing erosive arthritis in children, often progressing to disability. These children experience functional impairment due to joint and back pain, heel pain, swelling of joints and morning stiffness, contractures, pain, and anterior uveitis leading to blindness. As children who have juvenile arthritis reach adulthood, they face possible continuing disease activity, medication-associated morbidity, and life-long disability and risk for emotional and social dysfunction. In this article we will review the burden of juvenile arthritis for the patient and society and focus on the following areas: patient disability; visual outcome; other medical complications; physical activity; impact on HRQOL; emotional impact; pain and coping; ambulatory visits, hospitalizations and mortality; economic impact; burden on caregivers; transition issues; educational occupational outcomes, and sexuality. The extent of impact on the various aspects of the patients', families' and society's functioning is clear from the existing literature. Juvenile arthritis imposes a significant burden on different spheres of the patients', caregivers' and family's life. In addition, it imposes a societal burden of significant health care costs and utilization. Juvenile arthritis affects health-related quality of life, physical function and visual outcome of children and impacts functioning in school and home. Effective, well-designed and appropriately tailored interventions are required to improve transitioning to adult care, encourage future vocation/occupation, enhance school function and minimize burden on costs.

    The objective of this study was to analyze social representations of diabetes mellitus by chronic patients in a neighborhood in Guadalajara, Mexico. The methodology was qualitative and ethnographic. Thirty patients were interviewed at four moments over the course of two years, and the interviews were transcribed and analyzed with a dialectic hermeneutic focus using the Ethnograph software. The main results include a holistic representation of the disease, with multi-causality and key differences according to gender, allowing the expression of body sensations, pain, images, and individual meanings, the perception of a contaminated, unnatural physical environment, and a social context with economic limitations and affective, family, and marital problems. Diabetes is a means of expression, a vehicle, and a catalyst in an adverse environment which allows organizing what are perceived as negative internal and external events.

    For reproduction of chronic hyperimmunocomplexemia model the classic Cochrane C. G., 1973 elaboration was used. The circulating immune complexes (CIC) were identified by precipitation methods, and fixated--by immunofluorescent in endothelium reproduction of aorta, and their clearance organs--liver and spleen. The estimation of neutrophil status was carried out according to rosette-forming neutrophils ability--by latex, zimosane, mieloperoxidasa, NST tests. The growth of large and middle CIC in vessel bed was estimated, their fixation in aorta bifurcation, and also on liver and spleen calls, but their intensivity is less, comparing to aorta endothelium. The neutrophil status was characterised by O-neutrophils growth, strengthening of capturing macrophages function, considerable activation of fermentative polynuclear systems, although reserve possibilities in them grew in less degree. Morphologic investigations allow to speak mediatingly about neutrophils participation in endotheliocytes damage, and also about their ability to secure the mononuclear cells further participation in damaging of aorta walls and partially of liver and spleen.

    Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is an immune-mediated demyelinating disease of the peripheral nervous system. Th17 and Th1 cells contribute to the pathogenesis of most autoimmune diseases, but little is known about their distribution and reciprocal relationship in CIDP. In this study, we analyzed the distribution of Th17, Th1, and Th17/Th1 cells in the peripheral blood and cerebrospinal fluid (CSF). The results showed that the frequency of Th17 cells was significantly higher in the peripheral blood mononuclear cell (PBMCs) and CSF of active CIDP in comparison with remitting CIDP or to other non-inflammatory neurological diseases (ONDs), accompanied by similar findings for Th17/Th1 cells. Both active and remitting CIDP have higher percentage of Th1 cells in the CSF than OND. CSF protein levels positively correlated with the frequencies of Th17 cells either in the PBMCs or CSF of active CIDP, while there was no significant correlation with Th1 cells. In line with these observations, the levels of interleukin-17 (IL-17) in plasma and transcript factors retinoic acid receptor-related orphan receptor (ROR)γt expressed by PBMCs were significantly higher in the active CIDP than remitting CIDP or OND. In summary, our preliminary findings suggest that elevated numbers of inflammatory T cells, especially for Th17 cells, might be an important determinant in the evolution of CIDP.

    B cell antihost antibody production plays a central role in chronic graft-versus-host disease (cGVHD). T follicular helper (TFH) cells drive B cell responses and are implicated in this process. Given differences in cGVHD incidence between umbilical cord blood (UCB) and adult donor transplant recipients, we evaluated TFH cell reconstitution kinetics to define graft source differences and their potential pathogenic role in cGVHD. Although we observed significantly fewer TFH cells in the blood of UCB recipients (versus matched related donors [MRD]) early after transplantation, by 1 year the numbers of TFH cells were similar. Additionally, at both early (day 60) and late (1 year) time points, TFH cell phenotype was predominantly central memory cells in both cohorts. TFH cells were functional and able to produce multiple cytokines (INF-γ, TNF-α, IL-2, IL-17, and IL-21) after stimulation. In contrast to mouse models, where an enhanced frequency of splenic TFH cells contributes to cGVHD, patients with cGVHD showed significantly depleted circulating TFH cells after both UCB and MRD transplantation. Low numbers of TFH cells early after UCB transplantation could directly contribute to less cGVHD in this cohort. Additionally, systemic therapy (including steroids and calcineurin inhibitors) may contribute to decreases in TFH cells in patients with cGVHD. These data provide further evidence supporting the importance of TFH cells in cGVHD pathogenesis.

    This study examined the effects of 2 wk of high-NaCl diet on kidney function and dynamic renal blood flow autoregulation (RBFA) in rats with adenine-induced chronic renal failure (ACRF). Male Sprague-Dawley rats received either chow containing adenine or were pair-fed an identical diet without adenine (controls). After 10 wk, rats were randomized to either remain on the same diet (0.6% NaCl) or to be switched to high 4% NaCl chow. Two weeks after randomization, renal clearance experiments were performed under isoflurane anesthesia and dynamic RBFA, baroreflex sensitivity (BRS), systolic arterial pressure variability (SAPV), and heart rate variability were assessed by spectral analytical techniques. Rats with ACRF showed marked reductions in glomerular filtration rate and renal blood flow (RBF), whereas mean arterial pressure and SAPV were significantly elevated. In addition, spontaneous BRS was reduced by ∼50% in ACRF animals. High-NaCl diet significantly increased transfer function fractional gain values between arterial pressure and RBF in the frequency range of the myogenic response (0.06-0.09 Hz) only in ACRF animals (0.3 ± 4.0 vs. -4.4 ± 3.8 dB; P renal failure by facilitating pressure transmission to the microvasculature.

    The acute (0.57 microg/kg i.v. in 2 hours) and long-term (0.57 microg/kg i.v. in 2 hours for 5 days over 4 weeks) effects of the PGE1 analogue alprostadil were studied in patients affected with intermittent claudication. Whole Blood Viscosity (WBV), Whole Blood Filterability (WBF), haematocrit (Htc) and fibrinogen plasma concentration, were studied together with P50, 2,3-diphosphoglycerate, and adenosine plasma levels. Moreover, in the long-term study, pain-free (PFWD) and maximal walking distance (MWD) were measured. Single alprostadil infusion induced an improvement in WBV, WBF, and oxygen transport, and an increase in adenosine plasma levels. Long-term alprostadil administration produced a decrease in WBV only, without significant changes in WBF, Htc, fibrinogen, P50, 2,3-diphosphoglycerate, also inducing a significant prolongation of PFWD and MWD. The possibility is suggested that pulse rises in adenosine plasma levels play a role in the effects of chronic alprostadil administration, maybe in a way similar to that observed in the phenomenon of ischaemic preconditioning,

    X-linked agammaglobulinemia (XLA) is a primary immunodeficiency disease caused by mutations in the Bruton's tyrosine kinase (BTK) gene. XLA can also present in combination with juvenile idiopathic arthritis (JIA), the major chronic rheumatologic disease in children. We report herein the first known case of a juvenile patient diagnosed with XLA combined with JIA that later developed into invasive Klebsiella pneumoniae polyarticular septic polyarthritis. An additional comprehensive review of XLA combined with JIA and invasive K. pneumoniae septic arthritis is also presented. XLA was identified by the detection of BTK mutations while the diagnosis of JIA was established by clinical and laboratory assessments. Septic arthritis caused by invasive K. pneumoniae was confirmed by culturing of the synovia and gene detection of the isolates. Invasive K. pneumoniae infections can not only result in liver abscesses but also septic arthritis, although this is rare. XLA combined with JIA may contribute to invasive K. pneumoniae infection.

    The incidence of chronic pancreatitis (CP) is increasing, and dyslipidemia severely affects the health of middle-aged and elderly people. We investigated the association between blood lipid levels and CP. The serum lipid metabolic indices of 48 patients with CP (CP group) were summarized retrospectively. The physical examination results of 40 randomly selected healthy individuals were used as the normal control (NC) group. Statistical analyses of the blood lipid data were performed between the 2 groups using the case-control study method. High-density lipoprotein-cholesterol (HDL-c) levels decreased and fasting blood glucose (GLU) levels increased in the CP group compared with those in the NC group (P<0.01). Pearson correlation analysis results showed that serum amylase (AMY) was positively correlated with low-density lipoprotein-cholesterol (LDL-c; r=0.414, P<0.05), and urine AMY (UAMY) was positively correlated with total cholesterol (TC; r=0.614, P<0.01) and LDL-c (r=0.678, P<0.01). A binary logistic regression analysis showed that GLU (odds ratio [OR], 5.052; P<0.01) and TC (OR, 1.074; P<0.01) may be risk factors for CP, whereas HDL-c may be a CP protective factor (OR, 0.833; P<0.01). The HDL-c levels decreased and GLU levels increased in the CP group compared with those in the NC group; AMY was positively correlated with LDL-c and UAMY was positively correlated with TC and LDL-c; GLU and TC may be risk factors for CP; and HDL-c may be a CP protective factor. This may be the first time that such results have been reported. These findings will contribute to primary prevention and control of CP progression.

    A blood sample from a 14-year-old dog was submitted to the veterinary diagnostic laboratory of the University of Milan for marked leukocytosis with atypical cells. A diagnosis of chronic T-cell lymphocytic leukemia (CLL) was made based on blood smear evaluation and flow cytometric phenotyping. A CBC by Sysmex XT-2000iV revealed a moderate normocytic normochromic anemia. Red blood cells counted by optic flow cytometry (RBC-O) resulted in a higher value than using electrical impedance (RBC-I). The relative reticulocyte count based on RNA content and size was 35.3%, while the manual reticulocyte count was < 1%. The WBC count of 1,562,680 cells/μL was accompanied by a flag. Manual counts for RBC and WBC using the Bürker chamber confirmed the Sysmex impedance results. Finally the manual PCV was lower than HCT by Sysmex. While Sysmex XT can differentiate between RBC and WBC by impedance, even in the face of extreme lymphocytosis due to CLL, RBC-O can be affected by bias, resulting in falsely increased RBC and reticulocyte numbers. Overestimation of RBC-O may be due to incorrect Sysmex classification of leukemic cells or their fragments as reticulocytes. This phenomenon is known as pseudoreticulocytosis and can lead to misinterpretation of regenerative anemia. On the other side PCV can be affected by bias in CLL due to the trapping of RBC in the buffy coat, resulting in a pink hue in the separation area. As HGB concentration is not affected by flow cytometric or other cell-related artifacts it may represent the most reliable variable to assess the degree of anemia in cases of CLL.

    AIM: To evaluate the gastric permeability after both acute and chronic use of non-steroidal anti-inflammatory drugs (NSAIDs) and to assess the clinical usefulness of sucrose test in detecting and following NSAIDs- induced gastric damage mainly in asymptomatic patients and the efficacy of a single pantoprazole dose in chronic users.METHODS: Seventy-one consecutive patients on chronic therapy with NSAIDs were enrolled in the study and divided into groups A and B (group A receiving 40 mg pantoprazole daily, group B only receiving NSAIDs). Sucrose test was performed at baseline and after 2, 4 and 12 wk,respectively. The symptoms in the upper gastrointestinal tract were recorded.RESULTS: The patients treated with pantoprazole had sucrose excretion under the limit during the entire follow-up period. The patients without gastroprotection had sucrose excretion above the limit after 2 wk, with an increasing trend in the following weeks (P = 0.000). A number of patients in this group revealed a significantly altered gastric permeability although they were asymptomatic during the follow-up period.CONCLUSION: Sucrose test can be proposed as a valid tool for the clinical evaluation of NSAIDs- induced gastric damage in both acute and chronic therapy. This tecnique helps to identify patients with clinically silent gastric damages. Pantoprazole (40 mg daily) is effective and well tolerated in chronic NSAID users.

    In nondialysis chronic kidney disease, ambulatory blood pressure (ABP) performs better than clinic BP in predicting outcome, but whether repeated assessment of ABP further refines prognosis remains ill-defined. We recruited 182 consecutive hypertensive patients with nondialysis chronic kidney disease who underwent 2 ABPs 12 months apart to evaluate the enhancement in risk stratification provided by a second ABP obtained 1 year after baseline on the risk (hazard ratio and 95% confidence interval) of composite renal end point (death, chronic dialysis, and estimated glomerular filtration rate decline ≥40%). The difference in daytime and nighttime systolic BP between the 2 ABPs (daytime and nighttime bias) was added to a survival model including baseline ABP. Net reclassification improvement was also calculated. Age was 65.6±13.4 years; 36% had diabetes mellitus and 36% had previous cardiovascular event; estimated glomerular filtration rate was 42.2±19.6 mL/min per 1.73 m(2), and clinic BP was 145±18/80±11 mm Hg. Baseline ABP (daytime, 131±16/75±10 and nighttime, 122±18/66±10 mm Hg) and daytime/nighttime BP goals (58.2% and 43.4%) did not change at month 12. Besides baseline ABP values, bias for daytime and nighttime systolic BP linearly associated with renal outcome (1.12, 1.04-1.21 and 1.18, 1.08-1.29 for every 5-mm Hg increase, respectively). Classification of patients at risk improved when considering nighttime systolic level at second ABP (net reclassification improvement, 0.224; 95% confidence interval, 0.005-0.435). Patients with first and second ABPs above target showed greater renal risk (2.15, 1.29-3.59 and 1.71, 1.07-2.72, for daytime and nighttime, respectively). In nondialysis chronic kidney disease, reassessment of ABP at 1 year further refines renal prognosis; such reassessment should specifically be considered in patients with uncontrolled BP at baseline.

    Proton induced X-ray emission (PIXE) analysis is used to measure trace element concentrations in blood serum from patients with rheumatoid arthritis. Initially trace element contaminations in blood-collecting and storing devices are determined. Then mean values and nyctemeral cycles are measured both in normal subjects and patients with rheumatoid arthritis and other similar pathologies. Abnormal concentrations of Cu and Zn and anomalies in the nyctemeral cycle are found in the patients. In the second phase of the project, the special case of chrysotherapeutically treated (gold salt treatment) rheumatoid arthritis patients is studied for extended periods of time (up to 53 weeks).

    This study examined brain functioning in patients with Lyme encephalopathy. Eleven patients underwent neuropsychological tests and Xenon(133)-regional cerebral blood flow (rCBF) studies, using an external detector system. Each rCBF scan was age- and sex-matched to two archival, normal controls. While few differences were noted on gray-matter flow indices (ISI, fg), Lyme patients demonstrated significant flow reductions in white matter index (k(2)) (p=.004), particularly in the posterior temporal and parietal lobes bilaterally (p=.003). Flow reductions in white matter areas were significantly associated with deficits in memory (r=.66, p=.027) and visuospatial organization (r=.62, p=.041). Results suggest that Lyme encephalopathy may be a disease primarily affecting the cerebral white matter.

    Background Blood pressure (BP) is often inadequately controlled in patients with chronic kidney disease (CKD). Previous reports of the longitudinal association between achieved level of BP and end-stage renal disease (ESRD) have not incorporated time-updated BP with appropriate adjustment for known confounders. Objective To assess the association between baseline and time-updated systolic BP (SBP) with the progression of CKD. Design Observational, prospective cohort study (ClinicalTrials.gov identifier: NCT00304148) Setting Seven US clinical centers Patients Participants of the Chronic Renal Insufficiency Cohort (CRIC) Study (N=3,708) followed for a median (25th, 75th percentiles) of 5.7 (4.6, 6.7) years Measurements The mean of three seated SBP measurements were used as the visit-specific SBP. SBP was time-updated as the mean of that visit and all prior visits. Outcomes were ESRD and the composite renal endpoint of ESRD (dialysis or transplantation) or halving of the estimated glomerular filtration rate (eGFR). Analyses investigating baseline and time-updated SBP utilized traditional Cox proportional hazards models and marginal structural models, respectively. Results SBP was ≥130 mmHg at all study visits in 19.2% of participants, and ≥140 mmHg in 10.6%. The hazard ratio (95% confidence interval) for ESRD among participants with SBP 130–139 mmHg, compared to SBP <120 mmHg, was 1.46 (1.13–1.88) using only baseline data, and was 2.37 (1.48–3.80) using all available time-updated data. Among those with SBP ≥140 mmHg, corresponding hazard ratios were 1.46 (1.18–1.88) and 3.37 (2.26–5.03), respectively. Limitations SBP was measured once annually, and the CRIC Study cohort is not a random sample. Conclusions Among participants in the CRIC Study, time-updated SBP over 130 mmHg was more strongly associated with progression of CKD than analyses based on baseline SBP. Funding The CRIC Study is funded under cooperative agreements from the National Institute of

    Full Text Available Background One of the problems of the patients with chronic obstructive pulmonary disease (COPD is the weakness of the respiratory muscles that causes oxygen desaturation at rest and activity and decreases exercise tolerance. Objectives This study aimed to investigate the effect of inspiratory muscle training on arterial oxygen saturation (SPO2. Patients and Methods Forty patients with mild to very severe COPD were recruited for this study, which is a randomized control trail. The patients were randomized to IMT (inspiratory muscle training and control group. Training was performed with Respivol (a kind of inspiratory muscle trainer for 8 weeks (15 min/d for 6 d/week. SPSS software version 16 was used to analyze the data by performing independent t test, paired t test, and Fisher exact test. Results Results showed that, after 8 weeks of inspiratory muscle training, there was a little increase (but not statistically significant improvement in SPO2 (from 92.6 ± 8.71 % to 95.13 ± 7.08 %, with P = 0.06, whereas it remained unchanged in the control group (from 96.0 ± 3.46 % to 96.4 ± 3.35 % with P = 0.51. No statistically significant difference was seen between the two groups (P > 0.05. Conclusions Although inspiratory muscles training can prevent desaturation, which is caused by activity, it fails to improve it.

    The validation of housekeeping genes (HKGs) for normalization of RNA expression in Real-Time PCR is crucial to obtain the most reliable results. There is limited information on reference genes used in the study of gene expression in milk somatic cells and the frozen whole blood of goats. Thus, the aim of this study was to propose the most stable housekeeping genes that can be used as a reference in Real-Time PCR analysis of milk somatic cells and whole blood of goats infected with caprine arthritis encephalitis virus (CAEV). Animals were divided into two groups: non-infected (N=13) and infected with CAEV (N=13). Biological material (milk somatic cells and whole blood) was collected 4 times during the lactation period (7, 30, 100 and 240days post-partum). The expression levels of candidate reference genes were analyzed using geNorm and NormFinder software. The stability of candidates for reference gene expression was analyzed for CAEV-free (control) and CAEV-infected groups, and also for both groups together (combined group). The stability of expression of β-actin (ACTB), glyceraldehyde-3P-dehydrogenase (GAPDH), cyclophilin A (PPIA), RNA18S1, ubiquilin (UBQLN1) and ribosomal protein large subunit P0 (RPLP0) was determined in milk somatic cells, while ACTB, PPIA, RPLP0, succinate dehydrogenase complex subunit A (SDHA), zeta polypeptide (YWHAZ), battenin (CLN3), eukaryotic translation initiation factor 3K (EIF3K) and TATA box-binding protein (TBP) were measured in frozen whole blood of goats. PPIA and RPLP0 were considered as the most suitable internal controls as they were stably expressed in milk somatic cells regardless of disease status, according to NormFinder software. Furthermore, geNorm results indicated the expression of PPIA/RPLP0 genes as the best combination under these experimental conditions. The results of frozen whole blood analysis using NormFinder software revealed that the most stable reference gene in control, CAEV-infected and combined groups is

    Although the use of corticosteroids in juvenile idiopathic arthritis (JIA) is now much more limited owing to the availability of methotrexate and biological agents, there are clinical scenarios where it is still indicated. For example, corticosteroids may be indicated for intraarticular injections to prevent joint deformities, as a "bridge" drug to relieve symptoms in polyarticular disease while waiting for methotrexate and biologics to exert their full therapeutic effects, and in the treatment of chronic iridocyclitis, macrophage activation syndrome, and systemic JIA, although the advent of interleukin (IL)-1 and IL-6 blockers has greatly reduced the latter indication.

    Full Text Available Psoriatic arthritis is a complex disease affecting primarily peripheral and axial joints and entheses together with the skin. The pathogenesis is characterized by a genetic background and by inflammatory mechanisms which may be triggered by environmental factors. Several susceptibility genes have been investigated; they include HLA genes, genes within the HLA region and genes outside the HLA region. T cells, including the recently described subset Th17, are thought to play an important role in the acute and chronic phases of the disease. Some of these findings allowed novel therapeutic interventions or opened new promising approaches in treatment. The most relevant data of the literature are summarized and discussed.

    T follicular helper cells (Tfh) provide help to B cells to support their activation, expansion and differentiation. However, the role of Tfh cells in chronic HBV infection is poorly defined. The aim of this research was to examine the function of Tfh cells and whether they are involved in HBV related disease. Blood CXCR5+CD4+T cells and B cells in 85 patients with chronic HBV infection (HBV patients) and health controls (HC) were examined by flow cytometry. The molecule expression in blood CXCR5+CD4+ T cells was detected by real-time PCR. Blood CXCR5+CD4+ T cells and B cells were co-cultured and the production of Ig and cytokines was detected by ELISA. Autoantibodies were detected by indirect immunofluorescence and immunospot assay. We found that blood CXCR5+CD4+ T cells in patients with chronic HBV infection (HBV patients) expressed higher level of activation related molecules and cytokines than that from health controls (HC).In HBV patients, the frequency of blood CXCR5+CD4+ T cells was significantly correlated with serum ALT and AST. We also found that blood CXCR5+CD4+ T cells from HBV patients could induce B cells to secret higher level of immunoglobulin than that from HC. Several autoantibodies, including ANA, ss-A, ss-B, Scl-70, Jo-1, ect, were indeed positive in 65% HBV patients. Among HBV patients, expression of function related molecules was significantly higher in blood CXCR5+CD4+ T cells from patients with autoantibodies than that without autoantibodies. Our research indicated that blood CXCR5+CD4+ T cells from HBV patients were over activated and show augmented capacity to help B cells for antibody secreting, which might correlated with liver inflammation and the production of autoantibodies in extrahepatic manifestations.

    Full Text Available The present study aims to analyse the effects of lead (Pb chronic exposure on blood lead levels, Monoamine oxidase A enzyme (MAO A and serotonin levels of brass craftsmen in Pati, Central Java, Indonesia, and to examine the connections among these three variables. The brass home industry area was polluted by lead. Thus, it chronically exposes the workers to lead pollution. Therefore, their blood lead level increased and later raised the level of MAO A and reduced the level of serotonin. Path analysis results show that the path coefficient (ñ of lead effects in decreasing serotonin through MAO A pathway is -0.411. Furthermore, lead effects that directly affect serotonin level without passing through MAO A pathway is -0.391 with residual coefficient (e of 0.572. In conclusion, the increase of blood lead level causes an increase in level of MAO A and drop in the level of serotonin.

    Full Text Available Atherosclerosis is a chronic inflammatory disease of the arteries. Clinical consequences of the atherosclerotic process occur in the adult population, however atherosclerotic process begins in childhood. The classic risk factors for atherosclerosis include obesity, dyslipidaemia, age, gender or family history. In recent years, attention has been drawn to the similarity between atherosclerotic inflammatory processes and inflammatory changes in the course of systemic connective tissue disease, in particular systemic lupus etythematosus (SLE or rheumatoid arthritis (RA. There is also observed the similarity of the pathogenetic background of development of atherosclerosis and juvenile idiopathic arthritis (JIA. Elevated levels of pro-inflammatory cytokines are observed in the course of juvenile idiopathic arthritis. Also homocysteine concentrations, which may play a significant role in the development of atherosclerotic lesions, are observed higher in patients with JIA. Some studies revealed higher carotid intima-media thickness (IMT index values in children with JIA. In view of the fact that atherosclerotic process begins as early as in childhood, the introduction of appropriate preventive measures in children is a matter of utmost importance.

    Trypanosoma cruzi (Tc) infection causes chagasic cardiomyopathy; however, why 30–40% of the patients develop clinical disease is not known. To discover the pathomechanisms in disease progression, we obtained the proteome signature of peripheral blood mononuclear cells (PBMCs) of normal healthy controls (N/H, n = 30) and subjects that were seropositive for Tc-specific antibodies, but were clinically asymptomatic (C/A, n = 25) or clinically symptomatic (C/S, n = 28) with cardiac involvement and left ventricular dysfunction. Protein samples were labeled with BODIPY FL-maleimide (dynamic range: > 4 orders of magnitude, detection limit: 5 f-mol) and resolved by two-dimensional gel electrophoresis (2D-GE). After normalizing the gel images, protein spots that exhibited differential abundance in any of the two groups were analyzed by mass spectrometry, and searched against UniProt human database for protein identification. We found 213 and 199 protein spots (fold change: |≥ 1.5|, p93% prediction success in classifying infected individuals with no disease and those with cardiac involvement and LV dysfunction. In conclusion, we have identified molecular pathways and a panel of proteins that could aid in detecting seropositive individuals at risk of developing cardiomyopathy. PMID:26919708

    The use of alcohol is increasingly prevalent in our country and remains associated with innumerable social and economic problems. In addition, brain abnormalities have been proved by means of neuroimaging techniques not only in the first days of withdrawal, but also months after the last use of the substance in the patients. The purpose of the present study was to investigate patterns of the regional cerebral blood flow (rCBF) in alcoholic dementia. Six patients (all men; 44-67 years, mean age = 57.5 years) who fulfilled DSM-IV criteria for alcoholic dementia were enrolled in the study. RCBF measurements of resting state using Tc-99m ethyl cysteinate dimmer (ECD) SPECT were performed. The SPECT image was obtained 40 minutes after intravenous injection of 1110 MBq of Tc-99m ECD using a dual-head gamma camera (ECAM plus; Siemens, Erlangen, Germany). The normalized SPECT data from the alcoholic dementia group were compared with those from 12 healthy subjects. Alcoholic dementia patients showed significant decrement of rCBF in the left thalamus, superior frontal gyrus of left frontal lobe, left insula, postcentral gyrus of left parietal lobe, parahippocapal gyrus of left limbic lobe, right caudate, and cingulate gyrus of right limbic lobe than age-matched healthy subjects. Despite the small number of patients examined, the study supports the belief that patients with alcohol induced cognitive dysfunction have the neuro pathophysiology as those with classical alcoholic dementia.

    The mechanisms supporting functional improvement by aerobic exercise following stroke remain incompletely understood. This study investigated how cycling intensity and aerobic fitness influence cerebral blood flow (CBF) following a single exercise session. Thirteen community-living stroke survivors performed 20 min of semi-recumbent cycling at low and moderate intensities (40-50 and 60-70 % of heart rate reserve, respectively) as determined from an exercise stress test. CBF was quantified by arterial spin labeling MRI at baseline, as well as 30 and 50 min post-exercise. An intensity-dependent effect was observed in the right post-central and supramarginal gyri up to 50 min after exercise (uncorrected p Aerobic fitness was directly related to posterior cingulate and thalamic CBF, and inversely related to precuneal CBF at rest (R (2) ≥ 0.75); however, no relationship between fitness and the post-exercise change in CBF was observed. Divergent changes in regional CBF were observed in the right parietal cortex following low- and moderate-intensity exercise, which suggests that intensity of prescribed exercise may be useful in optimizing rehabilitation.

    AIM: To study the dynamic changes of hepatits B virus (HBV) DNA in serum and peripheral blood mononuclear cells (PBMCs) of patients after lamivudine therapy.METHODS: A total of 72 patients with chronic HBV infection were included in this study. All patients were confirmed to have the following conditions: above 16 years of age, elevated serum alanine amonotransferase (ALT), positive hepatitis B e antigen (HBeAg), positive HBV DNA in serum and PBMCs, negative antibodies against HAV, HCV, HDV, HEV. Other possible causes of chronic liver damages, such as drugs, alcohol and autoimmune diseases were excluded. Seventy-two cases were randomly divided into lamivudine treatment group (n = 42) and control group (n = 30). HBV DNA was detected both in serum and in PBMCs by fluorescence quantitative polymerase chain reaction (PCR), during and after lamivudine treatment.RESULTS: In the treatment group, HBV DNA became negative both in serum and in PBMC, of 38 and 25 out of 42 cases respectively during the 48 Wk oflamivudine treatment, the negative rate was 90.5% and 59.5% respectively. In the control group, the negative rate was 23.3% and 16.7% respectively. It was statistically significant at 12, 24 and 48 wk as compared with the control group (P < 0.005). The average conversion period of HBV DNA was 6 wk (2-8 wk) in serum and 16 wk (8-24 wk) in PBMC.CONCLUSION: Lamivudine has remarkable inhibitory effects on HBV replication both in serum and in PBMCs.The inhibitory effect on HBV DNA in PBMCs is weaker than that in serum.

    Among those with moderate-to-advanced chronic kidney disease, the relationship between blood pressure (BP) and cardiovascular disease seems U shaped but is loglinear in apparently healthy adults. The SHARP (Study of Heart and Renal Protection) randomized 9270 patients with chronic kidney disease to ezetimibe/simvastatin versus matching placebo and measured BP at each follow-up visit. Cox regression was used to assess the association between BP and risk of cardiovascular disease among (1) those with a self-reported history of cardiovascular disease and (2) those with no such history and, based on plasma troponin-I concentration, a low probability of subclinical cardiac disease. A total of 8666 participants had a valid baseline BP and troponin-I measurement, and 2188 had at least 1 cardiovascular event during follow-up. After adjustment for relevant confounders, the association between systolic BP and cardiovascular events was U shaped, but among participants without evidence of previous cardiovascular disease, there was a positive loglinear association throughout the range of values studied. Among those with the lowest probability of subclinical cardiac disease, each 10 mm Hg higher systolic BP corresponded to a 27% increased risk of cardiovascular disease (hazard ratio, 1.27; 95% confidence interval, 1.11–1.44). In contrast, the relationship between diastolic BP and cardiovascular risk remained U shaped irrespective of cardiovascular disease history or risk of subclinical disease. In conclusion, the lack of a clear association between systolic BP and cardiovascular risk in this population seems attributable to confounding, suggesting that more intensive systolic BP reduction may be beneficial in such patients.

    Aim. We conducted a cost-effectiveness analysis of seven hepatitis C virus (HCV) testing strategies in blood donors. Methods. Three of the seven strategies were based on HCV diagnosis and reporting guidelines in Mexico and four were from previous and current recommendations outlined by the CDC. The strategies that were evaluated determine antibody levels according to the signal-to-cut-off (S/CO) ratio and use reflex Immunoblot (IMB) or HCV RNA tests to confirm true positive (TP) cases of chronic HCV infection. Costs were calculated from the perspective of the Mexican Institute of Social Security (IMSS). A decision tree model was developed to estimate the expected number of true positive cases and costs for the base-case scenarios and for the sensitivity analyses. Results. Base-case findings indicate an extended dominance of the CDC-USA2 and CDC-USA4 options by the IMSS Mexico3 and IMSS-Mexico1 alternatives. The probabilistic sensitivity analyses results suggest that for a willingness-to-pay (WTP) range of $0–9,000 USD the IMSS-Mexico1 strategy is the most cost-effective of all strategies ($5,000 USD per TP). The IMSS-Mexico3, IMSS-Mexico2, and CDC-USA3 strategies are also cost-effective strategies that cost between $7,800 and $8,800 USD per TP case detected. The CDC-USA1 strategy was very expensive and not cost-effective. Conclusions. HCV antibody testing strategies based on the classification of two or three levels of the S/CO are cost-effective procedures to identify patients who require reflex IMB or HCV RNA testing to confirm chronic HCV infection.

    Infection of pigs with CSFV can lead to either acute disease, resulting in death or recovery, or chronic disease. The mechanisms by which CSFV manipulates the pig's first line of defence to establish a chronic infection are poorly understood. Therefore, pigs were infected with moderately virulent CSFV, and whole blood was collected on a regular basis during a period of 18 days. Using whole-genome microarrays, time-dependent changes in gene expression were recorded in blood cells of chronically diseased pigs and pigs that recovered. Bioinformatics analysis of regulated genes indicated that different immunological pathways were regulated in chronically diseased pigs compared to recovered pigs. In recovered pigs, antiviral defence mechanisms were rapidly activated, whereas in chronically diseased pigs, several genes with the potential to inhibit NF-κB- and IRF3/7-mediated transcription of type I interferons were up-regulated. Compared to recovered pigs, chronically diseased pigs failed to activate NK or cytotoxic T-cell pathways, and they showed decreased gene activity in antigen-presenting monocytes/macrophages. Remarkably, in chronically diseased pigs, genes related to the human autoimmune disease systemic lupus erythematosus (SLE) were up-regulated during the whole period of 18 days. CSFV pathology in kidney and skin resembles that of SLE. Furthermore, enzymes involved in the degradation of 1,25-dihydroxyvitamin D3 and of tryptophan to kynurenines were expressed at different levels in chronically diseased and recovered pigs. Both of these chemical processes may affect the functions of T helper/regulatory cells that are crucial for tempering the inflammatory response after a viral infection.

    Background Dioxin is an industrial pollutant related to various diseases, but epidemiological data on its effects on the kidney are limited. Therefore, we conducted a study to evaluate the association between dioxin exposure and chronic kidney disease (CKD) and identify the related factors. Methods We conducted a community-based cross-sectional study and recruited participants from an area where the residents were exposed to dioxin released from a factory. We defined a “high dioxin level” as polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) ≥ 20 pg WHO98-TEQDF/g lipid in the serum and defined CKD as having an estimated glomerular filtration rate (e-GFR) ≤ 60 mL/min/1.73m2 or a diagnosis of CKD by a physician. The renal function was assessed between 2005 and 2010, and we excluded those who had had kidney diseases before the study started. Comparisons between patients of CKD and those who did not have CKD were made to identify the risk factors for CKD. Results Of the 2898 participants, 1427 had high dioxin levels, and 156 had CKD. In the univariate analyses, CKD was associated with high dioxin levels, age, gender, metabolic syndrome, diabetes mellitus, hypertension, and high insulin and uric acid levels. After adjusting for other factors, we found high dioxin levels (adjusted odds ratio [AOR] = 1.76, 95% confidence interval [CI]: 1.04–2.99), female gender (AOR = 1.74, 95%CI: 1.20–2.53), hypertension (AOR = 1.68, 95%CI: 1.17–2.42), high insulin levels (AOR = 2.14, 95% CI: 1.26–3.61), high uric acid levels (AOR = 4.25, 95% CI: 2.92–6.20), and older age (AOR = 4.66, 95% CI: 1.87–11.62 for 40–64 year and AOR = 26.66, 95% CI: 10.51–67.62 for age ≥ 65 year) were independent predictors of CKD. Conclusion A high dioxin level was associated with an increased prevalence of CKD. Therefore, the kidney function of populations with exposure to dioxin should be monitored. PMID:26963719

    Full Text Available Introduction: Arterial gas derangement could change urinary sodium excretion in Chronic Obstructive Pulmonary Disease (COPD patients.There are very few and conflicting data in regards to the measurement of fractional excretion of sodium in COPD patients. The main aim of this study was to assess the relationship between renal fractional excretion of sodium(FeNa with arterial blood gas and spirometric parameters in COPD. Materials and Methods: This study was a cross-sectional study performed on 40 consecutive stable COPD outpatients in 2 main general hospitals (Emam Reza, Ghaem in Mashhad/Iran between 2011 and 2012. We investigated the relationship of renal FeNa with arterial blood gas parameters including HCO3, PH, PaCO2 and PaO2, and spirometric parameters. Analysis was done by SPSS v16 with a statistically meaningful p value of less than 0.05. Results: Mean age was 65.97±10.77 SD years and female to male ratio was 0.26. A renal FeNa of less than 1% was presented in 27% patients. There was a significant, positive relationship between renal FeNa and PaO2 (P=0.005, r=0.456. The correlations between PaCO2, HCO3, PH and spirometric parameters were not seen (P>0.05, but there was a significant relationship between Urine Na and PaO2. Outstanding, it seems likely that kidneys of COPD patients are responsible for sodium retaining state particularly in the presence of hypoxemia. Conclusion: This study indicates that in COPD patients, PaO2 but not PaCO2 is related to renal FeNa which shows the probable role of hypoxemia on sodium output in COPD patients. However, some caution is needed for interpretation of the probable role of hypercapnia on sodium retention in COPD.

    The ocular and systemic characteristics of 160 patients with anterior uveitis and seronegative juvenile rheumatoid arthritis are reviewed. Chronic uveitis occurred in 131 patients, 76% of whom were girls. Both eyes were involved in 70% of the cases. Band keratopathy occurred in 41% of the eyes, cataract in 42%, and secondary glaucoma in 19%. Only 11 patients had uveitis before the onset of arthritis. Notable correlations included a pauciarticular onset of arthritis in 95% of the patients, and positive tests for antinuclear antibody in 82%. Of 29 patients with acute anterior uveitis, 27 were boys. The inflammation responded well to therapy, and serious complications did not occur. At follow-up 21 patients had typical ankylosing spondylitis, and five had sacroiliitis. The incidence of positive results of tests for HLA-B27 antigen was 94%.

    Rheumatoid arthritis is a chronic inflammatory debilitating disease triggered by a complex interaction involving genetic and environmental factors. Active smoking and occupational exposures such as silica increase its risk, suggesting that initial inflammation and generation of rheumatoid arthritis-related autoantibodies in the lungs may precede the clinical disease. This hypothesis paved the way to epidemiological studies investigating air pollution as a potential determinant of rheumatoid arthritis. Studies designed for epidemiology of rheumatoid arthritis found a link between traffic, a surrogate of air pollution, and this disease. Furthermore, a small case-control study recently found an association between wood smoke exposure and anticyclic citrullinated protein/peptide antibody in sera of patients presenting wood-smoke-related chronic obstructive pulmonary disease. However, reports addressing impact of specific pollutants on rheumatoid arthritis incidence and severity across populations are somewhat conflicting. In addition to the link reported between other systemic autoimmune rheumatic diseases and particulate matters/gaseous pollutants, experimental observation of exacerbated rheumatoid arthritis incidence and severity in mice models of collagen-induced arthritis after diesel exhaust particles exposure as well as hypovitaminosis D-related autoimmunity can help understand the role of air pollution in rheumatoid arthritis. All these considerations highlight the necessity to extend high quality epidemiological researches investigating different sources of atmospheric pollution across populations and particularly in low-and-middle countries, in order to further explore the biological plausibility of air pollution's effect in the pathogenesis of rheumatoid arthritis. This should be attempted to better inform policies aiming to reduce the burden of rheumatoid arthritis.

    Agricultural workers have physically demanding occupations. In this study of Saskatchewan farmers, the authors examined (1) self-reported prevalence of physician-diagnosed rheumatoid arthritis and osteoarthritis; and (2) the impact of these chronic arthridities on engagement in physical tasks related to farming. This study was conducted through a cross-sectional analysis of baseline data from the Saskatchewan Farm Injury Cohort Study in which 2,473 adult residents upon 1,216 farms participated. Collected survey data included demographic and health information; regional musculoskeletal symptoms for each participant assessed via the Standard Nordic Questionnaire; and engagement in various specific physical tasks or activities associated with mixed farming practices. Of the 2,473 respondents, 13% reported chronic arthritic diagnoses (10% osteoarthritis, 4% rheumatoid arthritis, with 1% from each category overlapping with both forms of arthritis). Participants reporting arthritis were more likely to also report disabling musculoskeletal symptoms involving their shoulders, elbows, hands, lower back, hips, knees, and ankles. Farmers with arthritis reported less participation in all physical farming activities studied, including various machinery operations, herd maintenance and veterinary activities, overhead work, shoveling/pitchfork work, and lifting/carrying. When adjusted for age, gender, and comorbidities, operation of combines and shoveling/pitchfork work continued to be significantly less engaged in by farmers with arthritis. The overall prevalence of arthritis was consistent with general population prevalence, although the category of rheumatoid arthritis was overrepresented. Farmers with arthritis were significantly less likely to participate in combine operation and shoveling/pitchfork chores compared with their counterparts without arthritis.

    Full Text Available Pseudogout is a crystal-induced arthropathy characterized by the deposition of calcium pyrophosphate dihydrate (CPPD crystals in synovial fluid, menisci, or articular cartilage. Although not very common, this entity can be seen in patients with chronic kidney disease (CKD. Septic arthritis due to Mycobacterium avium-intracellulare (MAI is a rare entity that can affect immunocompromised patients such as those with acquired immunodeficiency syndrome (AIDS or those who are on immunosuppressive drugs. Here, we describe a 51-year-old female who presented with fever, right knee pain, swelling, warmth, and decreased range of motion for several days. The initial assessment was consistent with pseudogout, with negative bacterial and fungal cultures. However, due to high white blood cell (WBC count in the synovial fluid analysis, she was empirically started on intravenous (IV vancomycin and piperacillin-tazobactam and discharged on IV vancomycin and cefepime, while acid-fast bacilli (AFB culture was still in process. Seventeen days later, AFB culture grew Mycobacterium avium-intracellulare (MAI, and she was readmitted for relevant management. This case illustrates that septic arthritis due to MAI should be considered in the differential diagnosis of septic arthritis in immunocompromised patients.

    Gestational diabetes mellitus (GDM) has long-term health consequences, and fetal exposure to a diabetic intrauterine environment increases cardiovascular risk for her adult offspring. Some part of this could be related to their endothelial progenitor cells (EPCs). Understanding the vessel-forming ability of human umbilical cord blood (HUCB)-derived endothelial colony-forming cells (ECFCs) against pathological stress such as GDM response to hypoxia could generate new therapeutic strategies. This study aims to investigate the role of chronic hypoxia in EPCs functional and vessel-forming ability in GDM subjects. Each ECFC was expressed in endothelial and pro-angiogenic specific markers, namely endothelial nitric oxide synthase (eNOS), platelet (PECAM-1) endothelial cell adhesion molecule 1, vascular endothelial-cadherin CdH5 (Ca-dependent cell adhesion molecule), vascular endothelial growth factor A, (VEGFA) and insulin-like growth factor 1 (IGF1). Chronic hypoxia did not affect CdH5, but PECAM1 MRNA expressions were increased in control and GDM subjects. Control hypoxic and GDM normoxic VEGFA MRNA expressions and hypoxia-inducible factor 1-alpha (HIF1α) protein expressions were significantly increased in HUCB ECFCs. GDM resulted in most failure of HUCB ECFC adaptation and eNOS protein expressions against chronic hypoxia. Chronic hypoxia resulted in an overall decline in HUCB ECFCs’ proliferative ability due to reduction of clonogenic capacity and diminished vessel formation. Furthermore, GDM also resulted in most failure of cord blood ECFC adaptation against chronic hypoxic environment. PMID:25565870

  13. Severity and patterns of blood-nerve barrier breakdown in patients with chronic inflammatory demyelinating polyradiculoneuropathy: correlations with clinical subtypes.

    Full Text Available OBJECTIVE: Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP is currently classified into clinical subtypes, including typical and atypical forms (multifocal acquired demyelinating sensory and motor neuropathy (MADSAM and distal acquired demyelinating symmetric neuropathy (DADS. The aim of this study was to elucidate the patterns and severity of breakdown of the blood-nerve barrier (BNB in each CIDP subtype. METHODS: We evaluated the effects of sera obtained from patients with typical CIDP, MADSAM and DADS and control subjects on the expression levels of tight junction proteins and transendothelial electrical resistance (TEER value in human peripheral nerve microvascular endothelial cells (PnMECs. RESULTS: The sera obtained from the patients with the three clinical phenotypes of CIDP decreased the amount of claudin-5 protein levels and TEER values in the PnMECs. In addition, the sera obtained from typical CIDP patients more prominently reduced claudin-5 protein levels and TEER values in the PnMECs than did that obtained from the MADSAM and DADS patients. Furthermore, the severity of BNB disruption after exposure to the sera was associated with higher Hughes grade, lower MRC score, more pronounced slowing of motor nerve conduction in the median nerve and higher frequency of abnormal temporal dispersion. CONCLUSIONS: Sera derived from typical CIDP patients destroy the BNB more severely than those from MADSAM or DADS patients. The extent of BNB disruption in the setting of CIDP is associated with clinical disability and demyelination in the nerve trunk. These observations may explain the phenotypical differences between CIDP subtypes.

    The “reverse dipping” blood pressure (BP) pattern has been studied among the general population and in individuals suffering from hypertension. However, the prognosis of this pattern in chronic kidney disease (CKD) patients is not known. We monitored BP throughout the day and followed health outcomes in 588 CKD patients admitted to our hospital. Time to all-cause mortality, cardiovascular mortality, renal events and cardiovascular events was recorded. Multivariate-adjusted Cox regression analyses were carried out to detect the prognostic value of a reverse dipping BP pattern. Prevalence of a “dipper”, “non-dipper” and “reverse dippers” was 34.69%, 43.54% and 18.03%, respectively. Patients with a reverse dipping pattern had a higher prevalence of total mortality, cardiovascular mortality, renal events and cardiovascular events than patients with a dipping pattern (P < 0.025). Multivariate-adjusted Cox regression analyses showed that reverse dippers (versus dippers) were associated with a higher risk of total mortality (hazard ratio [HR], 5.08; 95% confidence interval [CI], 1.79~14.47), cardiovascular mortality (4.17; 1.25~13.88), renal events (3.00; 1.59~5.65) and cardiovascular events (4.12; 1.78~9.51) even after adjustment by 24-h systolic BP. These data suggest that a reverse dipping BP pattern, independent of 24-h levels of systolic BP, has prognostic value in CKD patients not undergoing dialysis. PMID:27713498

    Since the advent of HAART, there have been substantial improvements in HIV patient survival; however, the prevalence of HIV associated dementia has increased. Importantly, HIV positive individuals who smoke progress to HIV associated neurological conditions faster than those who do not. Recent in vitro data have shown that pharmacological levels of saquinavir causes endothelial oxidative stress and significantly decreases Notch-4 expression, a primary protein involved in maintaining stability of blood-brain barrier (BBB) endothelium. This is concerning as nicotine can also generate reactive oxygen species in endothelium. It is largely unknown if pharmacological doses of these drugs can cause a similar in vivo down-regulation of Notch-4 and if there is a concurrent destabilization of the integrity of the BBB. The data herein show: (i) nicotine and protease inhibitors cause an additive oxidative stress burden in endothelium; (ii) that the integrity of the BBB is disrupted after concurrent chronic nicotine and protease inhibitor administration; and (iii) that BBB endothelial dysfunction is correlated with a decrease in Notch-4 and ZO-1 expression. Considering the high prevalence of smoking in the HIV infected population (3- to 4-fold higher than in the general population) this data must be followed up to determine if all protease inhibitors cause a similar BBB disruption or if there is a safer alternative. In addition, this data may suggest that the induced BBB disruption may allow foreign molecules to gain access to brain and be a contributing factor to the slow progression of HIV associated dementia.

    2010-11-01

    The characteristic radiographic hallmarks of chronic gouty arthritis are the presence of macroscopic tophi and erosions with overhanging edges and relative preservation of the joint space. In recent years there has been more insight into the processes underlying the development of bone erosions in gouty arthritis. This review discusses the mechanical, pathological, cellular and immunological factors that may have a role in the pathogenesis of bone erosions in gouty arthritis. It highlights the evidence suggesting that monosodium urate crystal deposition is associated with the presence of underlying osteoarthritis and the important role of osteoclasts and the receptor for activation of nuclear factor κ B (RANK) and RANK ligand (RANK-RANKL) pathway in the pathogenesis of gouty erosions. Gouty arthritis is primarily driven by interleukin 1β (IL-1β). IL-1β has been implicated in bone destruction and erosions in other inflammatory arthridities. Thus, future IL-1 inhibitors may prevent and treat erosion formation due to tophaceous gouty arthritis. This review discusses imaging modalities and highlights ultrasongraphic evidence suggesting a significant relationship between the presence of the gouty tophus and bone erosions as well as the frequent presence of persistent low-grade inflammation in asymptomatic chronic tophaceous gouty arthritis on high-resolution ultrasonography. It is the tophus eroding the underlying bone that is pivotal for the development of bone erosions in gouty arthritis.

    Full Text Available Clinically, there are some differences between rheumatoid arthritis (RA and Lyme disease. Although Lyme arthritis exhibits marked differences from RA, it can cause erosion at joint due to chronic proliferative synovitis as similar to RA. In the literature, a case was reported where both entities were seen together. In this manuscript, we aimed to present a case with symmetric arthritis at small hand joints and arthralgia at wrist that mimicked RA but diagnosed as Lyme disease by history, clinical presentation and laboratory findings, and successfully treated.

    Full Text Available Abstract Background Rheumatoid arthritis (RA, inflammatory bowel disease (IBD, and psoriasis are immune-mediated inflammatory diseases with similarities in pathophysiology, and all can be treated with similar biological agents. Previous studies have shown that there are gender differences with regard to disease characteristics in RA and IBD, with women generally having worse scores on pain and quality of life measurements. The relationship is less clear for psoriasis. Because treatment differences between men and women could explain the dissimilarities, we investigated gender differences in the disease characteristics before treatment initiation and in the biologic treatment prescribed. Methods Data on patients with RA or IBD were collected from two registries in which patients treated with biologic medication were enrolled. Basic demographic data and disease activity parameters were collected from a time point just before the initiation of the biologic treatment. For patients with psoriasis, the data were taken from the 2010 annual report of the Swedish Psoriasis Register for systemic treatment, which included also non-biologic treatment. For all three diseases, the prescribed treatment and disease characteristics were compared between men and women. Results In total, 4493 adult patients were included in the study (1912 with RA, 131 with IBD, and 2450 with psoriasis. Most of the treated patients with RA were women, whereas most of the patients with IBD or psoriasis were men. There were no significant differences between men and women in the choice of biologics. At treatment start, significant gender differences were seen in the subjective disease measurements for both RA and psoriasis, with women having higher (that is, worse scores than men. No differences in objective measurements were found for RA, but for psoriasis men had higher (that is, worse scores for objective disease activity measures. A similar trend to RA was seen in IBD

    2014-01-01

    Full Text Available Although biologic therapies have changed the course of rheumatoid arthritis (RA, today’s major challenge remains to identify biomarkers to target treatments to selected patient groups. Circulating micro(miRNAs represent a novel class of molecular biomarkers whose expression is altered in RA. Our study aimed at quantifying miR-125b in blood and serum samples from RA patients, comparing healthy controls and patients with other forms of rheumatic diseases and arthritis, and evaluating its predictive value as biomarker for response to rituximab. Detectable levels of miR-125b were measured in total blood and serum samples and were significantly elevated in RA patients compared to osteoarthritic and healthy donors. The increase was however also found in patients with other forms of chronic inflammatory arthritis. Importantly, high serum levels of miR-125b at disease flare were associated with good clinical response to treatment with rituximab three months later (P=0.002. This predictive value was not limited to RA as it was also found in patients with B lymphomas. Our results identify circulating miR-125b as a novel miRNA over expressed in RA and suggest that serum level of miR-125b is potential predictive biomarker of response to rituximab treatment.

    Septic pyogenic arthritis of the acromioclavicular joint is a rare entity that occurs in immunosuppressed patients or those with discontinuity of defense barriers. There are only 15 cases described in the literature. The diagnosis is based on clinical features and the isolation of a microorganism in synovial fluid or blood cultures. The evidence of arthritis by imaging (MRI, ultrasound or scintigraphy) may be useful. Antibiotic treatment is the same as in septic arthritis in other locations. Staphylococcus aureus is the microorganism most frequently isolated. Our objective was to describe the clinical features, treatment and outcome of patients diagnosed with septic arthritis of the acromioclavicular joint at a Rheumatology Department. We developed a study with a retrospective design (1989-2012). The medical records of patients with septic arthritis were reviewed (101 patients). Those involving the acromioclavicular joint were selected (6 patients; 6%).

  6. Prostaglandins and Rheumatoid Arthritis

    Directory of Open Access Journals (Sweden)

    Mohammad Javad Fattahi

    2012-01-01

    Full Text Available Rheumatoid arthritis (RA is a chronic, autoimmune, and complex inflammatory disease leading to bone and cartilage destruction, whose cause remains obscure. Accumulation of genetic susceptibility, environmental factors, and dysregulated immune responses are necessary for mounting this self-reacting disease. Inflamed joints are infiltrated by a heterogeneous population of cellular and soluble mediators of the immune system, such as T cells, B cells, macrophages, cytokines, and prostaglandins (PGs. Prostaglandins are lipid inflammatory mediators derived from the arachidonic acid by multienzymatic reactions. They both sustain homeostatic mechanisms and mediate pathogenic processes, including the inflammatory reaction. They play both beneficial and harmful roles during inflammation, according to their site of action and the etiology of the inflammatory response. With respect to the role of PGs in inflammation, they can be effective mediators in the pathophysiology of RA. Thus the use of agonists or antagonists of PG receptors may be considered as a new therapeutic protocol in RA. In this paper, we try to elucidate the role of PGs in the immunopathology of RA.

    Telomere shortening to a critical limit is associated with replicative senescence. This process is prevented by the enzyme telomerase. Oxidative stress and chronic inflammation are factors accelerating telomere loss. Chronic hemodialysis, typically accompanied by oxidative stress and inflammation, may be also associated with replicative senescence. To test this hypothesis, we determined telomere length and telomerase activity in peripheral blood mononuclear cells (PBMCs) in a cross-sectional study. Hemodialysis patients at the University Hospital Larissa and healthy controls were studied. Telomere length was determined by the TeloTAGGG Telomere Length Assay and telomerase activity by Telomerase PCR-ELISA (Roche Diagnostics GmbH, Mannheim, Germany). We enrolled 43 hemodialysis patients (17 females; age 65.0 ± 12.7 years) and 23 controls (six females; age 62.1 ± 15.7 years). Between the two groups, there was no difference in telomere length (6.95 ± 3.25 vs. 7.31 ± 1.96 kb; P = 0.244) or in telomerase activity (1.82 ± 2.91 vs. 2.71 ± 3.0; P = 0.085). Telomere length correlated inversely with vintage of hemodialysis (r = -0.332, P = 0.030). In hemodialysis patients, positive telomerase activity correlated with telomere length (r = 0.443, P = 0.030). Only age, and neither telomere length nor telomerase activity, was an independent survival predictor (hazard ratio 1.116, 95% confidence interval 1.009-1.234, P = 0.033). In this study, telomere length and telomerase activity in PBMCs are not altered in hemodialysis patients compared with healthy controls. Long duration of hemodialysis treatment is associated with telomere shortening and positive telomerase activity with an increased telomere length in PBMCs of hemodialysis patients. The underlying mechanism and clinical implications of our findings require further investigation.

Adapting to disability and limitations caused by an illness is very difficult for many patients. The main goal of a therapeutic procedure should be improvement of health-related quality of life (QoL.Objective: Evaluation of the factors that influence the QoL that are conditioned by the state of health of patients with osteoarthritis (OA and rheumatoid arthritis (RA.Methods: The study group consisted of 198 patients diagnosed with OA, according to the American College of Rheumatology criteria (1988, and 100 patients diagnosed with RA, according to the American College of Rheumatology criteria (2010. A diagnostic survey using visual analog scale of pain, health assessment questionnaire disability index, and 36-item short form health survey were used in this study.Results: The average age of patients with OA was 59.16 (±15.87 years and patients with RA was 55.22 (±14.87 years. The average duration of illness examined for OA was 5.5 (±4.32 years, whereas for RA, it was slightly more at 6.8 (±5.21 years. Overall the QoL in both study groups was of medium level. Among patients with OA and RA, lower evaluation of QoL was mainly affected by age (OA – physical sphere [PCS] rs=-0.177, P<0.012; MCS rs=-0.185,  P=0.008; RA – PCS rs=-0.234,  P=0.019; MCS rs=-0.208,  P=0.038, the level of physical disability (OA – PCS rp=-0.532,  P<0.001; MCS rs=-0.467,  P<0.001; RA – PCS rp=-0.326, P<0.001; MCS rs=-0.229, P<0.001, and pain (OA – PCS rp=-0

    This paper introduces a hedge operator based fuzzy divergence measure and its application in segmentation of leukocytes in case of chronic myelogenous leukemia using light microscopic images of peripheral blood smears. The concept of modified discrimination measure is applied to develop the measure of divergence based on Shannon exponential entropy and Yager's measure of entropy. These two measures of divergence are compared with the existing literatures and validated by ground truth images. Finally, it is found that hedge operator based divergence measure using Yager's entropy achieves better segmentation accuracy i.e., 98.29% for normal and 98.15% for chronic myelogenous leukocytes. Furthermore, Jaccard index has been performed to compare the segmented image with ground truth ones where it is found that that the proposed scheme leads to higher Jaccard index (0.39 for normal, 0.24 for chronic myelogenous leukemia).

    with RеA. We observed that Na+,K+-ATPase of peripheral blood lymphocytes of patients with RеA retains its endogenous receptor properties – sensitivity to ouabain does not change. It is assumed that under conditions of rheumatic pathology the impact on the Na+,K+-ATPase structure occurs both externally and on the cytoplasmic membrane surface. The above experimental data can be used for further clarification of the membrane mechanisms of ion exchange in immunocompetent cells of patients suffering from autoimmune diseases.

    Full Text Available The aim of this research was to determine the clinical significance of tumor necrosis factor-alpha (TNF-alpha, IL-12, IL-15 and IL-18 in evaluation of the activity of rheumatoid arthritis. Cytokine concentrations in serum samples and synovial fluid were measured by immnnoenzymatic methods using kits for human interleukins and the Disease Activity Score 28 in 64 patients with active disease. The control group consisted of 25 subjects with arthritis of the knee and osteoarthrosis. Patients with rheumatoid arthritis have significantly high (p<0.01 concentrations of examined cytokines in relation to patients with osteoarthritis. By comparing concentrations in 30 patients with high, 14 patients with moderate and 20 patients with mild activity of rheumatoid arthritis, it was established that patients with high degree of disease activity have significantly high (p<0.01; p<0.05 concentrations of examined cytokines in the blood and synovial fluid in relation to patients with moderate and mild disease. We have concluded that cytokine concentrations are good indicators of the degree of rheumatoid arthritis activity. This research is a contribution to understanding the insufficiently known pathogenetic mechanisms of cytokines, especially IL-18, in active disease. .

    Juvenile rheumatoid arthritis (JRA) is the most common rheumatologic disease in children. Moreover, multiple sclerosis (MS) is the most frequent demyelinating disease and has been associated with various chronic inflammatory diseases. However, its association with JRA has not been frequently described. Autoimmunity in both JRA and MS has been documented in the scientific literature, although there has been no definitive finding that patients with JRA are prone to the development of MS. An increasing frequency of MS resulting from an increased use of antitumor necrosis factor agents in the treatment of rheumatoid arthritis and other chronic inflammatory diseases has been reported recently. In this study, we report on the development of MS in a patient with JRA who did not have a history of antitumor necrosis factor use.

    Smudge cells has been classically associated with chronic lymphocytic leukemia (CLL), but they are found in peripheral blood tests for other chronic B-cell lymphoproliferative diseases (CLD). We investigated whether the percentage of smudge cells in peripheral blood smears can be used in the clinical practice to differentiate CLL from other B-cell CLD. The peripheral blood smears of 63 patients with the diagnosis of CLL and 62 with other B-cell CLD were analyzed. Three hundred cells (both lym...

    Full Text Available Introduction. Nontyphoidal salmonellosis causes significant morbidity, is transmitted via fecal-oral route, and is a worldwide cause of gastroenteritis, bacteremia, and local infections. Salmonella is a less common etiologic factor for septic arthritis compared with other gram-negative bacteria. Cases. We present two septic arthritis cases with Salmonella enteridis as a confirmed pathogen and also discuss the predisposing factors and treatment. Discussion. Septic arthritis is an orthopedic emergency. The gold standard treatment of septic arthritis is joint debridement, antibiotic therapy according to the culture results, and physiotherapy, which should start in the early postoperative period to prevent limitation of motion. Salmonella is an atypical agent for septic arthritis. It must be particularly kept in mind as an etiologic factor for the acute arthritis of a patient with sickle cell anemia and systemic lupus erythematosus. Clinicians should be cautious that the white blood cell count in synovial fluid can be under 50.000/mm3 in immune compromised individuals with septic arthritis. The inflammatory response can be deficient, or the microorganism may be atypical. Conclusion. Atypical bacteria such as Salmonella species in immune compromised patients can cause joint infections. Therefore, Salmonella species must always be kept in mind for the differential diagnosis of septic arthritis in a clinically relevant setting.

    The rational of this study we intended to investigate whether the peripheral blood immunological/virological biomarkers were associated with distinct patterns of sleeping quality in patients with chronic hepatitis C-(HCV). Distinct well-established indexes/scores were used to categorize the sleeping quality of HCV patients, including the Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale and Fatigue Severity Scores. Our findings demonstrated that HCV patients classified as 'good sleeper' displayed an enhanced frequency of circulating CD8(+) T cells, lower frequency of activated (CD69(+)) neutrophils and eosinophils but enhanced frequency of activated lymphocytes besides lower seric levels of IL-4/IL-8/IL-10 but higher levels of IL-12, besides lower HCV virus load and lower anti-HCV IgG levels. In contrast, HCV patients classified as 'poor sleeper' displayed enhanced levels of activated neutrophils and eosinophils but lower frequency of activated lymphocytes, higher seric levels of IL-6/TNF-α/IL-10 but lower levels of IL-12 besides higher HCV virus load and increased anti-HCV IgG levels. Positive correlation was further confirmed by the relationship between the leucocyte activation status, the cytokine levels, the HCV viral load and the anti-HCV IgG reactivity with the PSQI indexes. Analysis of cytokine signature curves demonstrated that lower frequency of IL-10 was observed in HCV patients classified as 'good sleepers', whereas enhanced frequency of IL-6 was found HCV patients classified as 'poor sleepers'. In conclusion, our data suggest that immunological biomarkers (leucocytes activation status and seric cytokines levels) are likely to be associated with sleeping quality patterns in HCV patients, suggesting their putative use for clinical monitoring purposes.

    Plasma proadrenomedullin (ProADM) is a blood biomarker that may aid in multidimensional risk assessment of patients with chronic obstructive pulmonary disease (COPD). Co-secreted 1:1 with adrenomedullin (ADM), ProADM is a less biologically active, more chemically stable surrogate for this pluripotent regulatory peptide, which due to biological and ex vivo physical characteristics is difficult to reliably directly quantify. Upregulated by hypoxia, inflammatory cytokines, bacterial products, and shear stress and expressed widely in pulmonary cells and ubiquitously throughout the body, ADM exerts or mediates vasodilatory, natriuretic, diuretic, antioxidative, anti-inflammatory, antimicrobial, and metabolic effects. Observational data from four separate studies totaling 1366 patients suggest that as a single factor, ProADM is a significant independent, and accurate, long-term all-cause mortality predictor in COPD. This body of work also suggests that combined with different groups of demographic/clinical variables, ProADM provides significant incremental long-term mortality prediction power relative to the groups of variables alone. Additionally, the literature contains indications that ProADM may be a global cardiopulmonary stress marker, potentially supplying prognostic information when cardiopulmonary exercise testing results such as 6-min walk distance are unavailable due to time or other resource constraints or to a patient's advanced disease. Prospective, randomized, controlled interventional studies are needed to demonstrate whether ProADM use in risk-based guidance of site-of-care, monitoring, and treatment decisions improves clinical, quality-of-life, or pharmacoeconomic outcomes in patients with COPD.
