30521818 | Hide and seek. | 2020 Jan | A 51-year-old woman with a previous history of rheumatoid arthritis experienced painless progressive visual loss in the left eye for 3 weeks. Fundus examination revealed optic disk pallor in her left eye. Magnetic resonance imaging of the brain and orbits showed enhancement of the pachymeninges and hypersignal at the left optic nerve. Meningeal biopsy was performed. Immunohistochemical staining for IgG4 revealed several IgG4-positive plasma cells, which in some areas reached the number of 50Â cells/high-power field. In this case, the clinical and histopathological features of the patient met diagnostic criteria for rheumatoid arthritis and IgG4-related disease, respectively. Rheumatoid arthritis sometimes occurs with abundant IgG4 plasma cells and fulfills the histological diagnostic criteria for IgG4-related disease. This case demonstrates that overlapping features of IgG4-RD and rheumatoid arthritis may present in a single patient. | |
30398007 | Group therapy in a cohort study of Egyptian patients with rheumatoid arthritis. | 2019 Apr | INTRODUCTION: Rheumatoid arthritis (RA) affects many individuals' issues beyond those which are medically treated. OBJECTIVE: To study the impact of group therapy sessions on disease activity and functional abilities in RA patients. METHODS: One hundred and two patients with RA were divided into two groups; group A included 52 RA patients receiving their regular medical care in addition to group therapy sessions (cases); and group B included 50 RA patients receiving their regular medical care only (controls). Demographic, clinical and serological data were prospectively evaluated. All patients were assessed by using the Disease Activity Score of 28 joints (DAS28) and modified Health Assessment Questionnaire - Disability Index (mHAQ-DI), Hospital Anxiety and Depression scale (HAD) before, during and after group therapy sessions. RESULTS: Group A showed a statistically significant improvement in DAS28 at the 3rd and 6th months (P < 0.01 and P < 0.04) respectively, significant improvement in mHAQ score at the 3rd and 6th months (P < 0.02 and P < 0.00) respectively, and significant improvement in HAD scale for depression and anxiety (P <0.001). In group A there was no significant correlation between DAS28 and both anxiety or depression (P = 0.6, r = 0.5 and P = 0.06, r = 0.06) respectively, but on correlating mHAQ to both anxiety and depression, there was a statistically significant positive correlation at 6 months (P = 0.01, r = 0.3 and P = 0.03, r = 0.3) respectively. CONCLUSION: Group therapy sessions improve disease outcome, functional disability and psychological well-being in RA patients. | |
29731453 | [Diagnosis and treatment of rheumatoid arthritis:toward the best practice. How to use the | 2018 | Clinical Practice Guidelines are statements that include recommendations intended to optimize patient care. In the management of rheumatoid arthritis, many guidelines including ACR/EULAR recommendation, JCR guideline 2014 and number of JCR guidelines for each drug use have been published. The methodology to establish guidelines has been progressed, but work load for the guideline has become incredibly heavy. Legal position of guideline is also to be discussed. | |
28970218 | Mortality following new-onset Rheumatoid Arthritis: has modern Rheumatology had an impact? | 2018 Jan | OBJECTIVE: To investigate if, and when, patients diagnosed with rheumatoid arthritis (RA) in recent years are at increased risk of death. METHODS: Using an extensive register linkage, we designed a population-based nationwide cohort study in Sweden. Patients with new-onset RA from the Swedish Rheumatology Quality Register, and individually matched comparators from the general population were followed with respect to death, as captured by the total population register. RESULTS: 17 512 patients with new-onset RA between 1 January 1997 and 31 December 2014, and 78 847 matched general population comparator subjects were followed from RA diagnosis until death, emigration or 31 December 2015. There was a steady decrease in absolute mortality rates over calendar time, both in the RA cohort and in the general population. Although the relative risk of death in the RA cohort was not increased (HR=1.01, 95% CI 0.96 to 1.06), an excess mortality in the RA cohort was present 5 years after RA diagnosis (HR after 10 years since RA diagnosis=1.43 (95% CI 1.28 to 1.59)), across all calendar periods of RA diagnosis. Taking RA disease duration into account, there was no clear trend towards lower excess mortality for patients diagnosed more recently. CONCLUSIONS: Despite decreasing mortality rates, RA continues to be linked to an increased risk of death. Thus, despite advancements in RA management during recent years, increased efforts to prevent disease progression and comorbidity, from disease onset, are needed. | |
30025953 | Impact of comorbidities on fatigue in rheumatoid arthritis patients: Results from a nurse- | 2019 Jan | OBJECTIVES: To analyze the factors associated with fatigue focusing on comorbidities in a large cohort of rheumatoid arthritis (RA). METHODS: Cross-sectional analyses were performed on RA patients from the French COMEDRA cohort study, a nurse-led program for comorbidities management. Fatigue was assessed using Question 3 of the Rheumatoid Arthritis Impact of Disease (RAID) score on a 0-10 numerical rating scale (NRS). Fatigue was defined as acceptable if ≤ 2, moderate if 3 or 4, or severe if ≥ 5 out of 10. Using univariate and multivariate models, the relationship between fatigue and demographics, social, disease characteristics, comorbidities (cardiovascular, infections, cancer, pulmonary, osteoporosis, and psychiatric disorders), physical activity, quality of life, and treatments was investigated. RESULTS: In total, 962 patients were analyzed. The mean fatigue score was 3.8 ± 2.7, 40% of patients reported severe fatigue. Patients had an average of 1.8 additional morbid conditions, with anxiety/depression the most common (52%). In univariate analysis, severe fatigue was more frequent in women, in patients not working, and in those with less physical activity. It was associated with disease duration and activity, mHAQ, pain, sleeping and emotional difficulties. Severe fatigue correlated with Multimorbidity index assessing the number of morbid conditions and was associated with obesity, hypertension, COPD, and anxiety/depression. In multivariate models, the risk of severe fatigue was associated with female gender, disease activity, mHAQ, current treatment with NSAIDs and biologics, multimorbidity, obesity and anxiety/depression. CONCLUSIONS: Assessment of comorbidities, psychological health and physical activity should be taken into account in order to address frequent RA-related severe fatigue. | |
30206675 | Magnetic resonance imaging of the craniovertebral junction in early rheumatoid arthritis. | 2019 Apr | OBJECTIVE: To assess the involvement of the atlantoaxial joint in patients with early rheumatoid arthritis (ERA) and to elucidate the risk profile for the individual patient. MATERIALS AND METHODS: Consecutive ERA patients (disease duration < 12 months) were included in our study. A cervical spine magnetic resonance imaging (MRI) and X-rays (cervical spine, hands, wrists, and feet) were performed in all patients. The MRI features were correlated with clinical, radiological, and biochemical variables. RESULTS: Fifty patients (13 men and 37 women) with a mean age of 58.2 years (range, 36-79 years) were included in the study. In 12 (24%) patients were detectable MRI findings suggestive of the craniovertebral junction involvement. Compared with patients without cervical involvement, the patients with atlantoaxial synovitis showed a significantly higher anti-citrullinated protein antibodies (ACPA) titer [mean 200.25 UI (SD 262.44) vs. mean 22.05 (SD 40.21) (p < 0.001)]; a worse Disease Activity Score 44 joints (DAS44) [mean 5.72 (SD 0.44) vs. mean 4.52 (SD 0.53) (p < 0.001)]; a worse Health Assessment Questionnaire Disability Index (HAQ-DI) [mean 1.55 (SD 0.37) vs. mean 1.09 (SD 0.33) (p < 0.001)], and a higher Simple Erosion Narrowing Score (SENS) [mean 15.83 (SD 4.52) vs. mean 7.71 (SD 3.43) (p < 0.001)]. The multivariate analysis revealed a meaningful relationship between atlantoaxial synovitis and ACPA, DAS44, and the presence of an erosive disease. CONCLUSIONS: The craniovertebral junction is frequently involved in ERA patients. ACPA, high disease activity, and erosive disease at baseline are predictors of atlantoaxial involvement. | |
30320486 | The association between albumin-dNLR score and disease activity in patients with rheumatoi | 2019 Mar | BACKGROUND: Recently, clinical studies have described an association between albumin and the derived neutrophil to lymphocyte ratio (dNLR) with several diseases. This study was aimed to investigate the albumin-dNLR (ALB-dNLR) score in rheumatoid arthritis (RA) patients and assess its relationship with clinical and laboratory parameters of RA. METHODS: We retrospectively enrolled 127 RA patients, 155 osteoarthritis (OA) patients, and 155 healthy controls. The ALB-dNLR score was based on serum albumin level, neutrophil count, and white cell count. The Spearman's rank test was used to measure the correlations between ALB-dNLR score and disease activity as well as laboratory indexes. RESULTS: The ALB-dNLR score was significantly higher in RA patients than in OA patients (PÂ <Â 0.001) and in healthy controls (PÂ <Â 0.001). The proportion of higher ALB-dNLR score has been raised along with increased disease activity (PÂ <Â 0.001). The Spearman's rank test showed that ALB-dNLR score was positively associated with DAS28 score, CRP, ESR, IgA, and platelet count. Moreover, the receiver operating characteristic (ROC) curve showed that the area under the curve (AUC) of ALB-dNLR was 0.693 (95% CI: 0.631-0.755), which was higher than that of albumin (AUC: 0.625, 95% CI: 0.559-0.692) and dNLR (AUC: 0.680, 95% CI: 0.617-0.743) alone. CONCLUSIONS: The results demonstrate that the ALB-dNLR score increased in RA patients. The ALB-dNLR score may be a useful marker to estimate the disease activity of RA patients. | |
30431075 | Serum PGLYRP‑1 is a highly discriminatory biomarker for the diagnosis of rheumatoid arth | 2019 Jan | Peptidoglycan recognition protein‑1 (PGLYRP‑1) is a part of the innate immune system. It is well‑known that dysregulation of innate immune responses is present in patients with rheumatoid arthritis (RA). However, the role of Pglyrp1/PGLYPR‑1 in RA is poorly understood. Reverse transcription‑quantitative polymerase chain reaction was used to detect the level of Pglyrp1 in peripheral blood mononuclear cells. An ELISA was used to measure the level of PGLYPR‑1 in the serum, and correlation analysis was performed to analyze the association between the level of PGLYPR‑1 in the serum and clinical characteristics. A receiver operating characteristic (ROC) curve was constructed to evaluate the diagnostic value of PGLYPR‑1 in serum. The expression of PGLYPR‑1 in the serum of healthy controls compared with PGLYPR‑1 in the serum from patients with RA was significantly increased compared with patients with systemic lupus erythematosus (SLE). The level of PGLYPR‑1 in serum was correlated with rheumatoid factor and anti‑cyclic citrullinated peptide. ROC curve analysis suggested that PGLYPR‑1 in the serum may have significant value for RA diagnosis. In addition, the risk score based on PGLYPR‑1 in the serum also significantly discriminated the patients with RA from the disease controls (SLE). The present study suggested that increased expression of PGLYPR‑1 in the serum from patients with RA may serve as a potential biomarker for RA diagnosis. | |
30429411 | Effects of Ghrelin on the Apoptosis of Rheumatoid Arthritis Fibroblast-Like Synoviocyte MH | 2019 Feb 1 | Ghrelin is a circulating peptide hormone, which involved in promoting feeding and regulating energy metabolism in human and rodents. Abnormal synovial hyperplasia is the most important pathologic hallmark of rheumatoid arthritis (RA), which is characterised by tumor-like expansion. Existing studies indicated that there may exist some relation between the decreased ghrelin and the abnormally proliferating synovial cells in RA. Therefore, the aim of this study is to explore the apoptotic effects of ghrelin on MH7A synovial cells in vitro. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay was used to evaluate the effects of ghrelin on the viability of MH7A cells. Terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate-biotin nick-end labeling (TUNEL) and flow cytometry were used to test the apoptotic effects of ghrelin. At last, Western blot and real-time PCR were performed to explore the expression of caspases-8, -9, and -3 after the treatment of ghrelin. MTT experiments showed that ghrelin could inhibit viability of MH7A cells. The results of flow cytometry and TUNEL showed that ghrelin could induce apoptosis of MH7A synovial cells. Western blot showed that expression of cleaved-caspases-8, -9, and -3 were increased in ghrelin stimulation group compared with the control group, while expression of pro-caspases-8, -9, and -3 had no significant difference. In mRNA levels, ghrelin can decrease pro-caspases-8, -9, and -3 mRNA expression, which confirmed the results of protein levels. Then these apoptotic effects were significantly reversed by [D-Lys(3)] GHRP-6 (ghrelin receptor antagonist). This study found that ghrelin can induce apoptosis of MH7A cells through caspase signaling pathways. | |
30338418 | Systematic Review and Meta-analysis: Mindfulness-Based Interventions for Rheumatoid Arthri | 2018 Oct 18 | PURPOSE OF REVIEW: To determine the efficacy of mindfulness-based interventions (MBIs) on clinical and patient-reported outcomes in rheumatoid arthritis (RA). RECENT FINDINGS: We identified randomized clinical trials from inception through April 2018 from MEDLINE, PsycINFO, EMBASE, CINAHL, Web of Science, the Cochrane Library, and hand searches. After screening 338 references, we included five trials with one post-hoc analysis that evaluated MBIs and collectively included 399 participants. Outcome instruments were heterogeneous across studies. Three studies evaluated RA clinical outcomes by a rheumatologist; one study found improvements in disease activity. A limited meta-analysis found no statistically significant difference in the levels of DAS28-CRP in the two studies that evaluated this metric (- 0.44 (- 0.99, 0.12); I(2) 0%). Four studies evaluated heterogeneous psychological outcomes, and all found improvements including depressive symptoms, psychological distress, and self-efficacy. A meta-analysis of pain Visual Analog Scale (VAS) levels post intervention from three included studies was not significantly different between MBI participants and control group (- 0.58 (- 1.26, 0.10); I(2) 0%) although other studies not included in meta-analysis found improvement. There are few trials evaluating the effect of MBIs on outcomes in patients with RA. Preliminary findings suggest that MBIs may be a useful strategy to improve psychological distress in those with RA. | |
30506404 | Evaluation of cytokine profiles in rheumatoid arthritis patients with clinically active di | 2019 Apr | OBJECTIVE: To assess the potential utility of a cytokine measurement in rheumatoid arthritis (RA) patients with active joint disease but normal acute phase reactants (APR). METHODS: RA patients in a longitudinal observational registry with available cytokine array data were included. Patients were categorized based on agreement/disagreement of physical examination and APR measurements: concordant high (CH) [high tender and/or swollen joint counts (TJC + SJC > 3) and APR (ESR ≥ 28 mm/h + CRP ≥ 1.5 mg/L)]; concordant low (CL) [TJC + SJC ≤ 3 and normal APR]. Discordant (D) [TJC + SJC > 3 and normal APR] patients were stratified into low, medium, and high-disease activity (DL, DM, DH). Weighted-average and log-transformed cytokine scores were calculated based on results of a cytokine array. Chi-square tests compared categorical variables by concordance status; t tests, Wilcoxon rank-sum tests, ANOVA models, and ordinary least squares (OLS) regressions were used to compare continuous measures. RESULTS: RA patients (n = 1467) were predominantly male (91%). Compared to CH patients (n = 174), D (n = 434) were younger, less frequently seropositive, with lower TJC, SJC, and DAS28-3v scores (p < 0.001). Cytokine scores for DL, DM, and DH groups were lower than CH patients (p < 0.001) and did not differ between DL, DM, and DH subgroups and were similar to CL (n = 356) patients. In multivariable analyses including CH and D patients, log-cytokine score was associated with higher DAS28-3v scores (p = 0.029). In multivariable analyses including CL patients, concordance status (p = 0.011) and ACPA (p = 0.013) were predictors of higher log cytokine score. CONCLUSION: In this study, cytokine scores did not identify active joint disease in RA patients with normal APR. | |
29338885 | Concurrence of rheumatoid arthritis and calcium pyrophosphate deposition disease: A case c | 2018 Aug | OBJECTIVE: Calcium pyrophosphate deposition disease (CPDD) is arthritis caused by calcium pyrophosphate (CPP) crystal deposition in joints. It is commonly associated with aging as well as a handful of metabolic syndromes. Recent epidemiologic studies suggest a positive association of CPDD and rheumatoid arthritis (RA). Yet how these diseases are related remains unclear. We set out to describe 21 well-characterized patients with both diagnoses. METHODS: Medical records of patients with both RA and CPDD identified at a single academic practice site were reviewed for age, gender, age of CPDD and RA onset, disease duration, joint involvement, and lab values including rheumatoid factor (RF), cyclic citrullinated peptide antibody (CCP), iron studies, and parathyroid hormone and calcium levels. RESULTS: The mean age of CPDD onset was 69.5 ± 11.4 years, with a mean RA age onset of 53.9 ± 16 years, demonstrating a mean lag of 13.4 ± 10.9 years between diagnoses. The majority of RA patients were diagnosed with CPDD based on the presence of radiographic chondrocalcinosis (15/21). The most commonly involved joint was the knee, followed by the wrist, hip, and shoulder. CONCLUSIONS: These data show that the diagnosis of RA often precedes the diagnosis of CPDD. This asynchronous presentation taken together with the classic age of onset for CPDD and typical pattern of joint involvement supports the hypothesis that CPDD develops in RA patients through similar processes as those that cause the idiopathic forms of this disease. | |
29039214 | Pharmaceutical pricing in Japan: market evidence for rheumatoid arthritis treatment. | 2018 Jun | BACKGROUND: Drug price setting is one of the key challenges faced by the Japanese health care system. This study aims to identify the determinants of drug price in Japan using the example of the rheumatoid arthritis (RA) treatment market. RESEARCH DESIGN AND METHODS: In order to compare prices across different products, we calculated prices per defined daily dose using WHO methodology. Price determinants were calculated both at launch and over time using IMS quarterly data on medicines approved for RA treatment in Japan from 2012 to 2015. Pharmaceutical pricing was modeled as a function of clinical and economic variables using regression analysis. RESULTS: For prices at the launch we found that differences in efficacy are not reflected in price differentials. We also report that the number of products within a molecule class had a negative effect on prices while originator drugs maintained higher prices. CONCLUSION: Although the existing pricing rules in Japan are very comprehensive they do not necessarily capture differences in product characteristics. The findings here support the notion that competitive forces are weak in highly regulated markets such as Japan. | |
30150656 | Endogenous Galectin-9 Suppresses Apoptosis in Human Rheumatoid Arthritis Synovial Fibrobla | 2018 Aug 27 | Galectin-9 (Gal9) has been postulated to have anti-inflammatory properties based on the ability of exogenous Gal9 to induce apoptosis in synovial fibroblasts in animal models of rheumatoid arthritis (RA). Here we aimed to assess the potential role of endogenous Galectins, including Gal9, in the inflammatory pathology of the RA synovium in humans. Firstly expression of Galectins 1-9 was determined in synovial fibroblasts (RASF) and dermal fibroblasts (DF) isolated from RA patients, the latter representing a non-inflamed site. We then further challenged the cells with pro-inflammatory TLR agonists and cytokines and assessed Galectin expression. Gal9 was found to be differentially and abundantly expressed in RASF compared to DF. Agonists of TLR3 and TLR4, along with IFNgamma were also found to induce Gal9 expression in RASF. siRNA was then used to knock-down Gal9 expression in RASF and the effects of this on apoptosis and cell viability were assessed. Increased apoptosis was observed in RASF following Gal9 knock-down. We conclude that, unlike exogenous Gal9, endogenous Gal9 is protective against apoptosis and enhances synovial fibroblast viability suggesting that its role in RA is both pathogenic and pro-inflammatory. | |
29356697 | What is the optimal target for treat-to-target strategies in rheumatoid arthritis? | 2018 May | PURPOSE OF REVIEW: There has been a trend over time to aim for stricter treatment targets in the treatment of rheumatoid arthritis (RA). We reviewed recent literature to attempt to identify the optimal target in treat-to-target strategies in RA. RECENT FINDINGS: Achieving lower disease activity was shown to be beneficial, but few studies directly compared the effect of aiming for different treatment targets. Based on the limited available evidence, aiming for remission seems to result in more patients achieving (drug-free) remission than aiming for low disease activity (LDA), but it does not seem to result in better physical functioning. There are indications that adherence to a remission targeted protocol can be lower. In randomized trials in which LDA or remission were compared with ultrasound remission targets, treatment targeted at ultrasound remission was associated with more intensive treatment, but it did not result in better clinical or imaging outcomes. SUMMARY: There were no benefits of aiming for ultrasound remission in RA-patients. To decide whether remission or LDA is the best target in the treatment of RA-patients, a randomized clinical trial comparing both targets would be needed. On an individual level, cotargets such as functional ability should be considered. | |
29575958 | Overall benefits provided by orthopedic surgical intervention in patients with rheumatoid | 2019 Mar | OBJECTIVES: To clarify systemic effects of orthopedic surgical intervention in patients with rheumatoid arthritis (RA). METHODS: A prospective observational cohort study was performed in RA patients who were scheduled to have primary elective orthopedic surgeries. Assessments were performed at baseline, 6 and 12 months after surgery using J-HAQ, General Health, EQ-5D, BDI-II, DAS28-CRP(4) and CRP for all registered patients, DASH and grip power for patients with upper-extremity surgeries, TUG for patients with lower-extremity surgeries, and JSSF for patients with ankle and forefoot surgeries. RESULTS: There were 294 sites in 276 patients whose average age was 64 (19-89) years and average disease duration was 16 (1-60) years. Surgical site was shoulder in six patients, elbow in 26, wrist in 74, hand in 63, hip in 13, knee in 50, ankle in 12, and forefoot in 50. In total, physical function (J-HAQ, grip power, DASH, TUG, JSSF), quality of life (J-HAQ, General Health, EQ-5D) and depression (BDI-II) improved and disease activity (CRP, DAS28-CRP(4)) decreased significantly 6 and 12 months after surgery (p<.01), despite some differences in their outcomes by the preoperative disease activity and the surgical site. CONCLUSION: Overall benefits were provided by orthopedic surgical intervention generally in patients with RA. | |
30337216 | Serum free amino acid levels in rheumatoid arthritis according to therapy and physical dis | 2019 Jan | BACKGROUND: In presented study the amino acid analysis was performed in serum derived from rheumatoid arthritis patients (RA) according to undertaken therapy and classification of physical disability. The results were compared with previously published data. METHODS: The levels of 31 free amino acids were determined in 50 serum samples derived from RA subjects and 51 controls. The RA patients were divided into two groups according to the therapy (methotrexate/leflunomide, infliximab/adalimumab/etanercept/tocilizumab, prednisolone/NSAID) and classification of physical disability of the patients. Levels of amino acids were measured by LC-MS/MS. The obtained results were subjected to multivariate statistical tests. RESULTS: According to the therapy that was being used, threonine differentiated RA patients treated with methotrexate/leflunomide - infliximab/adalimumab/etanercept/tocilizumab (p = 0.00954) and infliximab/adalimumab/etanercept/tocilizumab - prednisolone/NSAID (p = 0.03109), while tryptophan differentiated RA patients treated with methotrexate/leflunomide - infliximab/adalimumab/etanercept/tocilizumab (p = 0.01723). In the functional classification, arginine differentiated RA samples between class III and IV (p = 0.02332), while glycine differentiated them between class I+II and III of the Steinbrocker functional classification (p = 0.03366). CONCLUSIONS: An analysis of the metabolome profile requires the use of validated bioanalytical methods that are strictly dedicated for this purpose. The obtained results are not accidental (p value less than 0.05), and all of the selected amino acids play an important role in inflammation and immune response. It is suggested that studied amino acids can be considered as a markers for diagnosis of RA and monitoring pharmacotherapy of the disease. | |
29577119 | Apoptosis effects of imperatorin on synoviocytes in rheumatoid arthritis through mitochond | 2018 Apr 25 | Rheumatoid arthritis (RA) is a systemic chronic inflammatory disease associated with a potential imbalance between the growth and death of rheumatoid arthritis fibroblast-like synoviocytes (RA-FLSs). Imperatorin (IPT) is a naturally occurring furanocoumarin found in umbelliferous vegetables, citrus fruits, and some herbs. The effects of IPT on the proliferation and apoptosis of RA-FLSs and its potential underlying mechanisms have remained unclear. RA-FLSs obtained from RA patients were induced by interleukin-1β (IL-1β) and treated with IPT. Cell viability was determined by MTT assay. Apoptotic cell death was analyzed by Annexin V-FITC/PI double staining and Hoechst 33342 staining. The loss in the mitochondrial membrane potential (ΔΨm) was visualized on the basis of JC-1 staining via fluorescence microscopy, and protein expression changes were assessed by western blot, whereas in vivo studies were conducted in male Wistar rats followed by histopathological assessment via TUNEL assay and HE staining of tissues. The results showed that IPT significantly reduced cell viability, accelerated cell apoptosis and decreased matrix metalloproteinases-1/-3 expression in IL-1β-induced RA-FLSs. Furthermore, IPT exposure was found to disrupt the ΔΨm compared to the IL-1β-induced treatment. Moreover, IPT increased the release of mitochondrial cytochrome C, the ratio of Bax/Bcl-2, and the cleavage of caspase-9, caspase-3 and poly (ADP-ribose) polymerase. In vivo studies showed that IPT not only significantly reduced the collagen induced arthritis by reducing synovial hyperplasia, and pannus formation but also enhanced the apoptotic index of ankle joint cells. Conclusively, our findings suggest that IPT inhibits cell proliferation and induces apoptosis in RA-FLSs that may be associated with mitochondrial/caspase-mediated signalling pathways. | |
29564803 | The impact of ocular manifestations of rheumatoid arthritis on the health-related quality | 2019 May | Objectives To determine the patterns, predictors and overall impact of ocular manifestations of rheumatoid arthritis (RA) on the health-related quality of life and disability index. METHODS: A total of 50 Nigerian patients with RA were studied. Full ocular evaluation was done to determine the presence of each defined ocular manifestation of RA. All patients completed the Medical Outcome Study 36-Item Short Form Health Survey (SF-36) and the Health Assessment Questionnaire-Disability Index (HAQ-DI) questionnaires. RESULTS: The mean ± SD age of the patients was 47.2 ± 12.5 years. A total of 42 cases of ocular diseases were found in 23 (46%) patients. Keratoconjunctivitis sicca was found in 15 (30%) patients; cataract, 13 (26%); scleritis/episcleritis, 4 (8%); disk edema, 4 (8%); glaucoma, 3 (6%); ulcerative keratitis, 1 (2%); vitreitis, 1 (2%); and macula edema, 1 (2%) patient. There is an association of the presence of ocular manifestations with the physical component summary (PCS) [T = - 3.398, P = 0.001] and the mental component summary (MCS) [T = - 2.616, 0.012] of the SF-36 but not with the HAQ-DI (T = 1.685, 0.099). Following multiple regression analysis, the predictors of the presence of ocular manifestations were age greater than 45 years and positive anti-citrullinated protein antibody. Following linear regression analyses, Steinbrocker's functional class independently predicted the PCS while both Steinbrocker's functional class and female sex predicted the MCS. CONCLUSIONS: The development of ocular disorders associated with RA is associated with a significant negative impact on the quality of life of the patients. | |
29722740 | Rheumatoid Meningitis: A Case Review. | 2018 May | INTRODUCTION: Rheumatoid meningitis (RM) is a rare complication of rheumatoid arthritis (RA) and has a high mortality rate. It can present as a first diagnosis of RA, in long-standing disease, or in active or well-controlled disease. Neurological manifestations vary widely. CASE REPORT: A patient with a 30-year history of RA, well controlled with methotrexate therapy, presented with new-onset seizures. Magnetic resonance imaging showed leptomeningeal and pachymeningeal enhancement. A de novo workup resulted in diagnosis of RM. CONCLUSIONS: Cerebrospinal fluid findings for RM are nonspecific, typically lymphocytic pleocytosis; however, they can be neutrophilic, as in this case. Magnetic resonance imaging findings consist of leptomeningeal and pachymeningeal enhancement but can also involve the parenchyma. The diagnosis is typically confirmed with meningeal biopsy. Treatment involves high-dose corticosteroids or immunomodulatory therapy, or both. Long-term follow-up with radiologic surveillance typically ranges from improvement to resolution. |
