22016756 | Sustained release myofascial release as treatment for a patient with complications of rheu | 2011 | BACKGROUND: Myofascial release (MFR) is a manual therapeutic technique used to release fascial restrictions, which may cause neuromusculoskeletal and systemic pathology. PURPOSE: This case report describes the use of sustained release MFR techniques in a patient with a primary diagnosis of rheumatoid arthritis (RA) and a secondary diagnosis of collagenous colitis. Changes in pain, cervical range of motion, fatigue, and gastrointestinal tract function, as well as the impact of RA on daily activities, were assessed. METHODS: A 54-year-old white woman presented with signs and symptoms attributed to RA and collagenous colitis. Pre and post measurements were taken with each treatment and during the interim between the initial and final treatment series. The patient recorded changes in pain, fatigue, gastrointestinal tract function, and quality of life. Cervical range of motion was assessed. Six sustained release MFR treatment sessions were provided over a 2-week period. Following an 8-week interim, two more treatments were performed. RESULTS: The patient showed improvements in pain, fatigue, gastrointestinal tract function, cervical range of motion, and quality of life following the initial treatment series of six sessions. The patient maintained positive gains for 5 weeks following the final treatment, after which her symptoms returned to near baseline measurements. Following two more treatments, positive gains were achieved once again. CONCLUSIONS: In a patient with RA and collagenous colitis, the application of sustained release MFR techniques in addition to standard medical treatment may provide short-term and long-term improvements in comorbid symptoms and overall quality of life. | |
21592375 | Femoral nerve palsy caused by ileopectineal bursitis after total hip replacement: a case r | 2011 May 18 | INTRODUCTION: Infectious ileopectineal bursitis is a rare complication after total hip replacement and is associated mainly with rheumatoid arthritis. The main complications are local swelling and pain, but communication of the inflamed bursa with the joint can occur, leading to subsequent cartilage damage and bone destruction. CASE PRESENTATION: We report a case of a 47-year-old Caucasian woman without rheumatoid arthritis who reported pain and palsy in her left leg almost one year after total hip replacement. She was diagnosed with an ileopectineal bursitis after total hip replacement, leading to femoral nerve palsy. The diagnosis was obtained by thorough clinical examination, the results of focused computed tomography and magnetic resonance imaging. CONCLUSION: To the best of our knowledge, this is the first report of non-infectious ileopectineal bursitis in a patient without rheumatoid arthritis as a complication of total hip replacement. This rare case underlines the importance of proper neurologic examination of persistent conditions after orthopedic intervention in otherwise healthy individuals. We believe this case should be useful for a broad spectrum of medical specialties, including orthopedics, neurology, radiology, and general practice. | |
22639744 | The effect of leflunomide on cold and vibratory sensation in patients with rheumatoid arth | 2012 Apr | OBJECTIVE: To evaluate the prevalence and risk factors of peripheral neuropathy in patients with rheumatoid arthritis (RA) treated with leflunomide (LEF) by quantitative sensory testing (QST). METHOD: A total of 94 patients were enrolledin this study, out of which 47 patients received LEF. The other 47 patients received alternative disease-modifying antirheumatic drugs and served as the control group. The demographic characteristics, laboratory findings, concomitant diseases, and medication history were evaluated at the time of QST. The cooling (CDT) and vibratory detection threshold (VDT) as the representative components of QST were measured. RESULTS: Age, gender, RA duration, ESR, and CRP did not show any significant differences between the two groups. VDT did not demonstrate any significant difference in both groups. However, CDT in LEF group was significantly higher than that of the control group (8.6±2.7 in LEF vs. 5.6±3.8 in control). The proportion of RA patients in the LEF group showing abnormally high CDT was over 2 times greater than that of the control group, but these findings were not statistically significant. Age, RA duration (or LEF medication in LEF group), ESR, and CRP did not show significant correlation with CDT in both groups. VDT significantly correlated with age in both groups. CONCLUSION: LEF treatment in patients with RA may lead to abnormal CDT in QST. CDT value was not affected by age, RA duration, disease activity, or LEF duration. It remains to be determined whether QST may be a valuable non-invasive instrument to evaluate the early sensory changes in patients with RA taking LEF. | |
22481985 | Agreement of Turkish physiatrists with the assessment in spondyloarthritis international s | 2012 | BACKGROUND: New developments in the field of targeted therapies or biologic agents led more effective management of ankylosing spondylitis (AS) and rheumatoid arthritis (RA). Recommendations for the management of rheumatic diseases propose to reduce inappropriate use of medications, minimize variations among countries, and enable cost-effective use of health care resources. OBJECTIVE: The aim this study was to evaluate conceptual agreement of ASsessment in SpondyloArthritis International Society (ASAS) and the EUropean League Against Rheumatism (EULAR) recommendations for the management of AS and EULAR recommendations for RA and to assess the rate of application among Turkish physiatrists in daily clinical practice. METHODS: An online survey link has been sent to 1756 Turkish physiatrists with e-mails asking to rate agreement on 11-item ASAS/EULAR AS recommendations and 15-item EULAR RA recommendations with synthetic and biological disease-modifying anti-rheumatic drugs. Also barriers and difficulties for using biologic agents were assessed. RESULTS: Three hundred nine physiatrists (17.5%) completed the survey. The conceptual agreement with both recommendations was very high (Level of agreement; mean 8.35±0.82 and 8.90± 0.67 for RA and AS recommendations, respectively), and the self-declared application of overall recommendations in the clinical practice was also high for both RA and AS (72.42% and 75.71%, respectively). CONCLUSION: Turkish physiatrists are in good conceptual agreement with the evidence-based recommendations for the management of AS and RA. These efforts may serve to disseminate the knowledge and increase the current awareness among physicians who serve to these patients and also implementation of these recommendations is expected to increase as well. | |
22347541 | Rheumatoid arthritis and periodontitis - inflammatory and infectious connections. Review o | 2012 | An association between oral disease/periodontitis and rheumatoid arthritis (RA) has been considered since the early 1820s. The early treatment was tooth eradication. Epidemiological studies suggest that the prevalence of RA and periodontitis may be similar and about 5% of the population are aged 50 years or older. RA is considered as an autoimmune disease whereas periodontitis has an infectious etiology with a complex inflammatory response. Both diseases are chronic and may present with bursts of disease activity. Association studies have suggested odds ratios of having RA and periodontitis varying from 1.8:1 (95% CI: 1.0-3.2, NS) to 8:1 (95% CI: 2.9-22.1, p<0.001). Genetic factors are driving the host responses in both RA and periodontitis. Tumor necrosis factor-α, a proinflammatory cytokine, regulates a cascade of inflammatory events in both RA and periodontitis. Porphyromonas gingivalis is a common pathogen in periodontal infection. P. gingivalis has also been identified in synovial fluid. The specific abilities of P. gingivalis to citrullinate host peptides by proteolytic cleavage at Arg-X peptide bonds by arginine gingipains can induce autoimmune responses in RA through development of anticyclic citrullinated peptide antibodies. In addition, P. gingivalis carries heat shock proteins (HSPs) that may also trigger autoimmune responses in subjects with RA. Data suggest that periodontal therapies combined with routine RA treatments further improve RA status. CONCLUSIONS: Periodontal infection (P. gingivalis) carries a unique risk for development of autoimmune antibodies associated with RA. Patients with RA have either lost many teeth or usually have severe periodontitis. Additional research, both in regards to basic mechanisms as well as clinical studies, are necessary before it can be said that there are causative links between RA and periodontitis. Cross-disciplinary research in well-defined populations should be performed to further enhance knowledge and develop clinical strategies how to coordinate therapy and risk assessments of RA and periodontitis. | |
24688908 | Development of a Rheumatoid Arthritis Education Program using the PRECEDE_PROCEED Model. | 2011 | BACKGROUND: In order to help rheumatoid arthritis (RA) patients in carrying out and at-taining relevant self-care behaviors and adaptation to the physical limitations of this dis-ease and, conse-quently, promoting their level of health status, an education program based on the PRECEDE component of the PRECEDE-PROCEED model targeting patients with RA was developed. This paper describes the planning of a RA Patient Education Program (RAPEP) designed to promote their quality of life. METHODS: The development of the program began with a comprehensive review of the li-terature. This included a review of the signs and symptoms of RA, accompanying func-tional disabilities, previous educational programs and the effect of the disease on the pa-tient's quality of life. Be-sides, in order to help inform RAPEP program development, and organize the survey according to the factors identified in the PRECEDE model a cross-sectional survey was applied on a non-prob-ability sample of 181 outpatients in Yazd, center of Iran. RESULTS: The quality of life (QOL) problem identified was the considerable low role func-tioning, health perception and physical functioning due to chronic pain. One of the most significant modi-fiable behavioral factors impacting pain and functional limitations was self-care behaviors in RA patients. Higher level of knowledge, attitude, self-efficacy, enabling factors and social support is associated with better self-care behavior. CONCLUSIONS: The PRECEDE component of the PRECEDE-PROCEED model provided a com-prehensive conceptual framework for the development of RAPEP aiming at RA pa-tients in Yazd. Further research to evaluate this educational program is suggested. | |
22944393 | Shoulder hemiarthroplasty: outcomes and long-term survival analysis according to etiology. | 2012 Oct | BACKGROUND: The indications for hemiarthroplasty in glenohumeral joint diseases remain controversial and depend mainly on the original underlying diagnosis. Our objective was to investigate the influence of the primitive aetiology on long-term prosthesis survival and on the Constant-Murley score. MATERIALS AND METHODS: We studied 272 shoulders with the following diagnoses: fracture sequelae (n=73), primary osteoarthritis (n=67), cuff tear arthropathy (n=43), avascular necrosis (n=40), rheumatoid arthritis (n=31), and other (n=18). Of the 272 shoulders, 139 were evaluated after at least 8 years (mean follow-up, 134 months). In all, 30 prostheses required removal. Functional status was evaluated using the Constant-Murley score and survival rate using the Kaplan-Meier method with prosthesis removal or conversion to total arthroplasty as the endpoint. RESULTS: Ten-year prosthesis survival was 88.13% overall, 100% in the rheumatoid arthritis group, 94.9% in the avascular necrosis group, 94.2% in the primary osteoarthritis group, 81.5% in the cuff tear arthropathy group, and 76.8% in the fracture sequelae (P=0.05). The mean Constant-Murley score after 8 years or more was 70.1 in avascular necrosis, 60.7 in primary osteoarthritis, 57.7 in fracture sequelae, 55.3 in rheumatoid arthritis, and 46.2 in cuff tear arthropathy (P=0.0006). The complication rate with the initial population as the denominator was 24.7% in fracture sequelae, 18.6% in cuff tear arthropathy, 15% in avascular necrosis, 8.9% in primary osteoarthritis, and 3.2% in rheumatoid arthritis. CONCLUSIONS: The best indication for shoulder hemiarthroplasty is avascular necrosis and the worst indications are cuff tear and post-traumatic fracture sequellae. Rheumatoid arthritis and primary glenohumeral osteoarthritis are good indications in patients younger than 50 years of age. LEVEL OF EVIDENCE: Level IV, retrospective study. | |
21660202 | Dyslipidaemia in rheumatological autoimmune diseases. | 2011 | Autoimmunity forms the basis of many rheumatological diseases, and may contribute not only to the classical clinical manifestations but also to the complications. Many of the autoimmune rheumatological diseases, including rheumatoid arthritis and systemic lupus erythematosus are associated with an excess cardiovascular morbidity and mortality. Much of this excess cardiovascular risk can be attributed to atherosclerotic disease. Atherosclerosis is a complex pathological process, with dyslipidaemia and inflammation fundamental to all stages of plaque evolution. The heightened inflammatory state seen in conjunction with many rheumatological diseases may accelerate plaque formation, both through direct effects on the arterial wall and indirectly through inflammation-mediated alterations in the lipid profile. Alongside these factors, antibodies produced as part of the autoimmune nature of these conditions may lead to alterations in the lipid profile and promote atherosclerosis. In this review, we discuss the association between several of the rheumatological autoimmune diseases and dyslipidaemia, and the potential cardiovascular impact this may confer. | |
22891151 | Effects of strengthening and aerobic exercises on pain severity and function in patients w | 2012 Jul | BACKGROUND: The purpose of this study was to investigate the effects of two types of rehabilitation techniques, including aerobic and strengthening exercises on patients with knee rheumatoid arthritis (RA). METHODS: 48 male patients with knee RA were randomly assigned into 3 groups, including aerobic exercises, strengthening exercise, and control. The two first groups completed their treatment protocol for 8 weeks, 3 days per week. Visual Analogue Scale, WOMAC questionnaire, 6-minute walking test, standard goniometer were used to assess pain severity, functional ability, walking ability, knee joint ROM respectively at baseline and after applying therapeutic interventions. The data were analyzed using one-way analysis of variance (ANOVA) at P < 0.05 significant level. RESULTS: Participants had a mean ± SD age of 58.6 ± 7.8 years (height 1.72 ± 0.07 m, weight 81.0 ± 6.4 kg) with no significant difference between three groups. Both therapeutic interventions reduced pain significantly (P < 0.001) compared to the control group, without significant difference between the two experimental groups. The patients fulfilled aerobic exercise attained higher levels of function and walking ability compared to strengthening group significantly (P < 0.001). The knee range of motion (ROM)wassignificantly (P < 0.001) improved in the two experimental groups in comparison to controls, the strengthening group had more significant (P < 0.001) improvement. CONCLUSIONS: It can be concluded that an aerobic exercise program improves functional and walking ability in patients with knee RA, and strengthening exercise has more efficient effect on knee ROM, both aerobic and strengthening exercises can equally relieve pain. | |
21792343 | TNF-α and TNF-β Gene Polymorphism in Saudi Rheumatoid Arthritis Patients. | 2011 | BACKGROUND: Tumor necrosis factor (TNF)-α and -β are cytokines with a wide range of inflammatory, apoptotic and immunomodulatory activities. TNF-α promoter -308 G < A polymorphism has been reported to be associated with rheumatoid arthritis (RA) with inconsistent results. OBJECTIVE: The aim of this study is to elucidate a possible association of TNF-α (G-308A) and TNF-β (A+252G) polymorphisms with the susceptibility of RA in Saudi patients. PATIENTS AND METHODS: This case control study consisted of 232 Saudi subjects including 106 RA patients and 126 matched controls. Genomic DNA was extracted using QIAamp(R) DNA mini kit (Qiagen CA, USA). TNF-α and TNF-β genes were amplified using Arms primers. RESULTS: The frequencies of TNF-α (-308) allele G and genotype GG were significantly higher in RA patients as compared to controls while allele A and genotype AA were predominant in control group. On the other hand the frequency of TNF-β (+252) GG and AA genotypes were significantly higher in RA patients as compared to controls while GA genotype was predominant in controls. It was inferred that genotype GG positive individuals at position -308 of TNF-α were susceptible to RA while genotype AA might has a protective effect on RA susceptibility in Saudis. Whereas GG and AA genotype of TNF-β at +252 position might exert additive susceptibility to RA and GA might be refractory. However, there was no significant association between duration of morning stiffness, RF positivity and number of joints involved and distribution of alleles/genotypes of TNF-α (-308) or TNF-β (+252) polymorphism. It may be concluded that the TNF-α (-308) and TNF-β (+252) polymorphisms might influence the susceptibility to RA in Saudi population. These results might have prognostic value for future clinical observations. | |
22611518 | Socioeconomic and employment status of patients with rheumatoid arthritis in Korea. | 2012 | OBJECTIVES: This study investigates the prevalence of rheumatoid arthritis (RA) by gender and socio-economic characteristics. It also explores the differences in the employment status between RA patients and the general population without RA in Korea. METHODS: We analyzed data from the Fourth Korea National Health and Nutrition Examination Survey (KNHANES IV) conducted from 2007 to 2009. Prevalence rates were estimated for female and male patients with RA in terms of age, residence, education, income level, and occupation type. The female respondents aged 45 to 64 were divided into the RA population and the non-RA population in order to compare the employment status between the two groups. RESULTS: The annual physician-diagnosed RA prevalence rate was 1.45%. The prevalence rate was 2.27% for women and 0.62% for men. Individuals with RA had a significantly lower employment rate than individuals without RA (41.7 vs. 68.1%). The main reason for non-employment among RA patients was health-related problems (47.1%). There was statistically significant difference in employment type among the two groups. The experience rates for sick leave and sick-in-bed due to RA were 1.7 and 3.9%, respectively. CONCLUSION: Middle- and old-aged women accounted for the majority of the Korean RA population, which had a significant lower employment rate compared to the population without RA for both sexes. RA resulted in considerable productivity loss in Korea. | |
27790005 | Certolizumab in the long-term treatment of rheumatoid arthritis. | 2011 | Rheumatoid arthritis is the most common inflammatory arthritis and continues to have major long-term effects on quality of life. Early and intensive treatment has now become the norm in clinical practice with changes of medication dictated by measuring the presence of continued disease activity. Biologics, particular tumor necrosis factor inhibitors, have a crucial role in the management of very severe disease. Certolizumab is a relatively new tumor necrosis factor inhibitor which uses a novel strategy to neutralize TNF-alpha - the conjugation of tumor necrosis factor specific Fab antibody fragments to polyethylene glycol. Two Phase II and three Phase III randomized controlled trials have evaluated the efficacy and toxicity of certolizumab. More than 2000 patients were enrolled, and followed from 12-52 weeks. The number of patients achieving significant improvements with certolizumab, was indicated by the American College of Rheumatology with a 50% response rate. The risk ratios of achieving this response at 24 weeks was 6.01 (95% confidence interval [CI]: 3.84-9.40). At 52 weeks the risk ratio was 5.27 (95% CI: 3.19-8.71). The number of patients needed to treat, to obtain this benefit at 24 weeks was 4 (95% CI: 3-5). Certolizumab also had important clinical benefits in reducing erosive damage to joints, limiting disability, and enhancing other outcomes of importance to patients such as fatigue. The patient-related benefits were present from the early weeks of treatment. The clinical trials showed serious adverse events, including infections, which were more frequent for certolizumab. The most common adverse events comprised upper respiratory tract infections, hypertension, and nasopharyngitis. The balance of evidence suggests that certolizumab is equivalent to other tumor necrosis factor inhibitors, though no head-to-head trials have been undertaken. Having several effective treatments available, benefits patient choice, because the frequency and route of administration of these treatments varies. Furthermore, as intolerance and antibody development against existing biologics is not uncommon, having several agents allows opportunities to switch from one inhibitor to another. | |
22870481 | Improved Sleep Efficiency after Anti-Tumor Necrosis Factor α Therapy in Rheumatoid Arthri | 2011 Oct | BACKGROUND: Poor sleep health is increasingly recognized as contributing to decreased quality of life, increased morbidity/mortality and heightened pain perception. Our purpose in this study was to observe the effect on sleep parameters, specifically sleep efficiency, in rheumatoid arthritis (RA) patients treated with anti-tumor necrosis factor alpha (anti-TNF-α) therapy. METHODS: This was a prospective observational study of RA patients with hypersomnolence/poor sleep quality as defined by the Epworth Sleepiness Scale (ESS) and Pittsburgh Sleep Quality Index (PSQI). Study patients underwent overnight polysomnograms and completed questionnaire instruments assessing sleep prior to starting anti-TNF-α therapy and again after being established on therapy. The questionnaire included the ESS, PSQI, the Berlin instrument for assessment of obstructive sleep apnea (OSA) risk, restless legs syndrome (RLS) diagnostic criteria, and measures of disease activity/impact. RESULTS: A total of 12 RA patients met inclusion criteria, of which 10 initiated anti-TNF-α therapy and underwent repeat polysomnograms and questionnaire studies approximately 2 months later. Polysomnographic criteria for OSA were met by 60% of patients. Following anti-TNF-α therapy initiation, significant improvements were observed by polysomnography (PSG) for sleep efficiency, increasing from 73.9% (SD 13.5) to 85.4% (SD 9.6) (p = 0.031), and 'awakening after sleep onset' time, decreasing from 84.1 minutes (SD 43.2) to 50.7 minutes (SD 36.5) (p = 0.048). Questionnaire instrument improvements were apparent in pain, fatigue, modified Health Assessment Questionnaire (mHAQ), and Rheumatoid Arthritis Disease Activity Index (RADAI) scores. CONCLUSIONS: Improved sleep efficiency and 'awakening after sleep onset' time were observed in RA patients treated with anti-TNF-α therapy. | |
23265174 | Dental surgery and anesthetic precautions of a patient with Down syndrome and juvenile rhe | 2012 Nov | Down syndrome and juvenile rheumatoid arthritis have been associated with ligament laxity, specifically the atlantoaxial ligament, which maintains the proper positioning of the cervical first and second vertebrae. The joint consists of different pathological processes, and it is paramount that individuals with either condition be screened appropriately before surgery is contemplated. The purpose of this paper was to present a case of an individual with both conditions and describe precautionary measures that were undertaken to safely complete dental treatment under general anesthesia and avoid morbidity. | |
23133752 | The role of different subsets of regulatory T cells in immunopathogenesis of rheumatoid ar | 2012 | Rheumatoid arthritis (RA) is a common autoimmune disease and a systemic inflammatory disease which is characterized by chronic joint inflammation and variable degrees of bone and cartilage erosion and hyperplasia of synovial tissues. Considering the role of autoreactive T cells (particularly Th1 and Th17 cells) in pathophysiology of RA, it might be assumed that the regulatory T cells (Tregs) will be able to control the initiation and progression of disease. The frequency, function, and properties of various subsets of Tregs including natural Tregs (nTregs), IL-10-producing type 1 Tregs (Tr1 cells), TGF-β-producing Th3 cells, CD8(+) Tregs, and NKT regulatory cells have been investigated in various studies associated with RA and collagen-induced arthritis (CIA) as experimental model of this disease. In this paper, we intend to submit the comprehensive information about the immunobiology of various subsets of Tregs and their roles and function in immunopathophysiology of RA and its animal model, CIA. | |
23024711 | Role of diagnostic ultrasound in the assessment of musculoskeletal diseases. | 2012 Oct | The wide availability and recent improvement in technology coupled with portability, low cost and safety makes ultrasound the first choice imaging investigation for the evaluation of musculoskeletal diseases. Diagnostic use of ultrasound findings is greatly enhanced by knowledge of the clinical presentation. Conversely, ultrasound skills with its prerequisite anatomical knowledge make the clinical diagnosis more precise and reduce uncertainty in the choice of therapy. Therefore, it is essential for rheumatologists to acquire ultrasonography skills in order to improve patient care. Ultrasound examination provides an excellent opportunity for patient education and to explain the rationale for therapy. This review summarizes the indications for musculoskeletal ultrasound and describes its role in diagnosis, monitoring and prognosis. | |
22279509 | The synovium in rheumatoid arthritis. | 2011 | Rheumatoid arthritis (RA) is a chronic autoimmune disease targeting multiple joints. The synovium is the primary site of the inflammatory process, which if untreated leads to irreversible damage to the adjacent cartilage and bone. It is now well established that autoantibodies that are characteristic of RA, including rheumatoid factor (RF) and anti-citrulluninated protein antibodies (ACPA), are present before clinical disease onset. Studies in both humans and animal models are beginning to provide new insights into how this asymptomatic autoimmunity evolves into an inflammatory process that is localized in the synovium.Once RA synovitis established, a number of amplification mechanisms serve to sustain the process leading to the persistence of the disease. These mechanisms include engagement of the resident mesenchymal cells and the establishment of ectopic lymphoid structures in the synovium, although the relationship between these lymphoid structures and the presence of RA autoantibodies remains unclear.An enhanced understanding of the mechanisms that initiate and sustain RA synovitis offers unprecedented opportunities for therapeutics, and ultimately prevention strategies. | |
21481278 | Effect of one week of yoga on function and severity in rheumatoid arthritis. | 2011 Apr 12 | BACKGROUND: Previous studies have shown that yoga practice improved the hand grip strength in patients with rheumatoid arthritis (RA). FINDINGS: Sixty-four participants with RA (group average age ± S.D., 46.5 ± 9.6 years; 47 females) were assessed at the beginning and end of a one week yoga program. The Stanford Health Assessment Questionnaire (HAQ), hand grip strength, rheumatoid factor, and C-reactive protein levels were assessed on the first and last day and compared using a t-test for paired data. All participants showed reduced disability scores of the HAQ and rheumatoid factor levels, with an increase in bilateral hand grip strength in male participants alone. CONCLUSIONS: This single group study indicated that a brief intensive yoga program was beneficial in RA, with decreased disability, better functionality and changes in the rheumatoid factor levels suggesting improvement. | |
22527139 | Hesperidin inhibits collagen-induced arthritis possibly through suppression of free radica | 2013 Mar | Rheumatoid arthritis is a chronic inflammatory disease characterized by the destruction of articular cartilage and bone in a chronic phase. Pathology of rheumatoid arthritis suggests autoimmunity linked to inflammation. In our study, rheumatoid arthritis was induced in Wistar rats by intradermal injections of 100 μl of emulsion containing bovine type II collagen in complete Freund's adjuvant at the base of the tail. Disease developed about 13 ± 1 days after immunization and treatment with hesperidin (HES) at a dose of 160 mg kg(-1) body weight was given after onset of disease daily until 20th day. The effect of treatment in the rats was monitored by clinical scoring, biochemical parameters and histological evaluations in joints. A steady increase in the articular elastase, nitric oxide and lipid peroxidation was observed in joints of arthritic rats as compared to control, whereas a significant decrease in reduced glutathione, superoxide dismutase activity and catalase was observed in collagen-induced arthritis rats as compared to control group. The results from the present work indicate that the treatment with hesperidin was effective in bringing about significant changes on all the parameters studied in collagen-induced arthritis rats. These data confirm that erosive destruction of the joint cartilage in collagen-induced arthritis is due free radicals released by activated neutrophils and produced by other biochemical pathways. In the present study, an attempt has been made to amelioration of the disease process by a natural product. These results suggest that oral administration of HES could be effective for treating human RA patients. | |
22147111 | Hepatitis B virus reactivation in a juvenile rheumatoid arthritis patient under treatment | 2013 May | Juvenile rheumatoid arthritis is a common chronic inflammatory disease in the childhood and it can differentiate rarely into spondiloarthropaties. It is one of the important causes of chronic pain and disability. Some of the drugs used for the treatment have immunosupressive activity. One of the serious side-effects of immunosupressive treatment is activation of opportunistic pathogens. Hepatitis B virus (HBV) is one of these pathogens, and the rate of carriers in the population is considerably high. It can cause liver damage and death if reactivated. Thus, the management of oppotunistic pathogens becomes a complex issue when treating rheumatic diseases with immunosupressive drugs. In this case report, we present a juvenile rheumatoid arthritis patient whose liver enzymes raised while he was under treatment and afterwards HBV reactivation was determined as the cause. When reactivation was detected, we started controlled antiviral therapy. We achieved successful clinical and laboratory results after adding biological agents to the treatment. Careful evaluation of the patients who have indication for immunosuppressive agents and regular follow-up in case of infection may be protective from severe morbidity and/or mortality. |
