32088752 | Strategies for implementation of guideline recommended cardiovascular risk management for | 2020 Apr | The aim was to study the different strategies used to implement cardiovascular risk evaluation and management for patients with rheumatoid arthritis (RA) in daily clinical practice. A questionnaire survey was performed among both the members of the international Trans-Atlantic Cardiovascular Risk Consortium for Rheumatoid Arthritis (ATACC-RA) as well as the Survey of cardiovascular disease risk factors (CVD-RF) in patients with RA (SURF-RA) group. The questionnaire included 18 questions with the overarching topics: (1) organization and responsibility of cardiovascular risk management (CVRM); (2) screening of CVD-RFs; (3) overview current CVRM status; and (4) availability of data regarding CVRM. Based on the answers, two researchers (JW, PR) independently categorized the different strategies. Thirteen out of 27 rheumatology centers responded to the questionnaire. One rheumatology center did not have organized CVRM for their RA patients. Among the other centers, three strategies to organize CVRM in daily practice were distinguished: (1) the rheumatologist performs CVRM during outpatient visits (n = 6); (2) cardiologists and rheumatologists co-operate in a cardio-rheuma-clinic/team with different tasks and responsibilities (n = 3); and (3) the general practitioner screens and intervenes on CVD-RFs (n = 3). Each CVRM strategy was based on agreements between medical professionals and was also dependent on the national healthcare system and available financial resources. Three strategies were identified for CVRM implementation in daily clinical practice based on who is primarily responsible for performing CVRM. More research is warranted to compare their relative merits and effectiveness in relation to CVRM. | |
31600398 | 'It can't be zero!' Difficulties in completing patient global assessment in rheumatoid art | 2020 May 1 | OBJECTIVES: Patient global assessment (PGA) is purported to add the patient's perspective in the composite measures of RA. However, PGA is not standardized and it is not known whether patients' interpretation of the measure is consistent with its intended purpose. This study aimed to explore difficulties experienced by patients with RA in completing PGA, and to assess the impact of a structured explanation in improving its validity and reliability. METHODS: This was a mixed methods study, using interviews, focus groups and PGA data. During interviews, patients (convenience sample, n = 33) completed three often-used PGA formulations. Then a nurse provided structured explanation about what PGA is and why it is used. After further discussion, patients completed one PGA version again. Interviews were recorded, transcribed and analysed using inductive thematic analysis. We compared PGA scores pre- and post-explanation (Wilcoxon signed-ranks) and the proportion of patients achieving RA remission with PGA ⩽1 (McNemar's tests). RESULTS: Three themes emerged: understanding the meaning of PGA, the purpose of PGA and measurement difficulties. The difficulties caused systematic errors in PGA completion such as marking higher when feeling well, marking near the centre or away from zero. The structured explanation was helpful. Following the explanation, the median PGA score decreased from 3.0 to 2.1 cm, and the proportion of non-remission solely due to PGA >1 from 52% to 41%; none of these changes was statistically significant. CONCLUSION: Many patients have difficulties in completing PGA. Standardization of PGA and a structured explanation may improve its clarity, validity and reliability. | |
31764591 | Prospective evaluation of phosphorus-32 radiation synovectomy in patients with severe and | 2020 Jan | OBJECTIVES: To determine the efficacy of Phosphorus-32 radiation synovectomy in the treatment of patients with severe rheumatoid arthritis (RA) unresponsive to systematic or local medical therapy. METHODS: Twenty-three knees in 16 patients with severe chronic RA were prospectively treated by intra-articular installation of Phosphorus-32 and evaluated at 1, 3, 6, and 12 months. The Western Ontario and McMaster Universities Arthritis index (WOMAC), visual analog scale (VAS), Health Assessment Questionnaire (HAQ), pain scale, and grade of joint effusion and tenderness were assessed. At the 12-month time interval, the treated knees were classified into four categories: excellent response (no symptoms), good response (significant reduction of symptoms), moderate response (slight decrease), and poor response (no change or worsening). RESULTS: Excellent response or good response was observed in 13/23 (56.5%) of the treated knees, moderate response in 2/23 (8.7%) of the treated knees, and poor response in 8/23 (34.8%) of the treated knees. The grades of effusion and tenderness were significantly decreased one-month posttreatment (P< 0.05); however, these changes did not persist at other time intervals (P > 0.05). There was a significant improvement in the HAQ, WOMAC, VAS, and pain scores at all time points compared with baseline, including at the 12-month time interval (P < 0.05). CONCLUSION: Phosphorus-32 radiosynovectomy is an effective therapeutic treatment for patients with RA of the knee unresponsive to conventional pharmacotherapy. | |
33349329 | Unilateral knee effusion in an elderly patient: an unusual presentation of rheumatoid arth | 2020 Dec | Unilateral atraumatic knee effusion is a relatively common presenting complaint among geriatric patients in primary care and musculoskeletal speciality clinics. Gout, pseudogout, degenerative joint diseases and reactive arthritis are the most common causes of the atraumatic knee effusions. Rheumatoid arthritis very rarely presents as arthritis of one or two large joints. Arthrocentesis, plain radiography and screening blood tests should be performed to help narrow the differential diagnosis. In some cases, advanced imaging modalities such as MRI may be indicated. This study reports a case of rheumatoid arthritis in a 75-year-old gentleman with oligoarthropathy of two large joints as the presenting symptoms. | |
32278813 | Basal metabolic rate and Charlson Comorbidity Index are independent predictors of metaboli | 2020 Oct | OBJECTIVE: To prospectively analyze predictors of metabolic syndrome (MetS) in patients with rheumatoid arthritis (RA) during 2years of follow-up. METHODS: We recruited 319 consecutive patients with RA who did not have MetS. MetS was defined in accordance with the modified National Cholesterol Education Program/Adult Treatment Panel III 2005 for Asian populations. Sociodemographic data, laboratory findings, disease activity data, and medication history were collected during face-to-face interviews at baseline and follow-up. Independent predictors of MetS were assessed by univariate and multivariate logistic regression analyses. RESULTS: Of the 247 patients with RA who completed the 2-year follow-up, 37 (15.0%) developed MetS. At baseline, these patients were older and had higher body mass index, waist circumference, waist-hip ratio, skeletal muscle mass, body fat mass, percent body fat, and Charlson Comorbidity Index scores, as well as lower basal metabolic rate (BMR). Moreover, these patients with MetS took less hydroxychloroquine and more oral hypoglycemic agents; they also had lower European Quality of Life Health-state Questionnaire scores. After exclusion of variables associated with MetS composition, multivariate analysis identified BMR (odds ratio [OR]=0.205, 95% confidence interval [CI]: 0.078-0.541, P=0.001) and Charlson Comorbidity Index score (OR=2.191, 95% CI: 1.280-3.751, P=0.004) as significant predictors of MetS. CONCLUSIONS: Our study showed that the annual incidence rate of MetS was 11.5% in patients with RA. Moreover, the development of MetS was associated with BMR and Charlson Comorbidity Index score at baseline. | |
32686533 | Presence of anti-citrullinated protein antibodies and costs and disease activity in early | 2020 Sep | Objective: To analyse healthcare utilization, loss of productivity, and disease activity in relation to presence of anti-citrullinated protein antibodies (ACPAs). Method: In total, 447 ACPA-positive and 224 ACPA-negative patients from two early rheumatoid arthritis cohorts, recruited 1996-1998 (cohort 1) and 2006-2009 (cohort 2), were followed during 3 years. Data on disease activity were collected, and patients reported healthcare utilization and days lost from work. Disease activity, healthcare costs, and loss of productivity were compared between ACPA groups. Linear regression was performed, controlling for confounders. Results: Healthcare costs did not differ significantly by ACPA status (EUR 3214 for vs EUR 2174 for ACPA-positive vs ACPA-negative patients in cohort 1, ns; EUR 4150 vs EUR 3820 in cohort 2, ns). Corresponding values for loss of productivity were EUR 9148 vs EUR 7916 (ns) and EUR 5857 vs EUR 5995 (ns). Total prescription of traditional disease-modifying anti-rheumatic drugs was higher in cohort 2 than in cohort 1. Methotrexate prescription was higher in ACPA-positive patients, but biologics did not differ significantly between ACPA groups. Disease activity was significantly more improved in cohort 2, but there was no difference in achieving remission in relation to ACPA status. In cohort 1, 25% of ACPA-positive patients were in remission vs 31% of ACPA-negative (ns) and in cohort 2, 55% vs 60% (ns). Conclusions: With increasing drug treatment for both ACPA-positive and ACPA-negative patients, outcome in ACPA-positive was no more severe than in ACPA-negative patients. Healthcare costs and loss of productivity were similar in the two groups. | |
31606775 | Cardiovascular risk factors' behavior during the early stages of the disease, in Hispanic | 2020 Mar | Rheumatoid arthritis (RA) patients from Latin America present distinctive characteristics relevant when assessing their cardiovascular (CV) risk. The objective was to monitor CV risk factor behavior in the early stages of the disease and to identify predictors of major CV outcomes (MACE). A recent-onset RA cohort was initiated in 2004; data from 185 patients with ≥ 1 year of follow-up were analyzed. Patients underwent prospective assessments of CV risk factors. Incident MACE were confirmed according to standardized definitions. Appropriated statics was used based on the distribution of the variables. At baseline, patients were primarily middle-aged females (87.6%), with active disease (69.7%). Most prevalent CV risk factors were C-reactive-protein > 1 mg/L (90.3%), Castelli ratio > 3 (83.8%), and low-high-density lipoprotein levels (73.5%). The number of patients with an incident CV risk factor after 1 year was higher for a Castelli ratio > 3 (23%), low-high-density lipoprotein serum cholesterol (16.3%), high total serum cholesterol (10.6%), and BMI ≥ 30 kg/m(2) (10%). A minority of patients met the age-range criteria for the application of ACC/AHA 2013 criteria and Reynolds Risk Score (45.8% and 34.1%, respectively). Fifteen patients were classified with high-CV risk during the first year of follow-up, according to ACC/AHA 2013 criteria. Until June 2018, the cohort underwent 1358 patient/years follow-up; six patients developed incidental MACE; high-CV risk at baseline failed to predict MACE. Recent-onset RA Hispanic patients present a distinctive pattern and first-year behavior of CV risk factors. During follow-up, few patients developed incidental MACE. | |
32357906 | Overlapping Sjogren's syndrome reduces the probability of reaching target in rheumatoid ar | 2020 May 1 | BACKGROUND: Overlapping Sjogren's syndrome (SS) is not uncommon in rheumatoid arthritis (RA) and considered as a probable detrimental factor of RA. But data on the impact of overlapping SS on RA therapeutic response is limited. Our current study aimed to identify the effect in a real-world cohort from 2009 to 2019. METHODS: The medical records of RA patients who visited the rheumatology clinic of our medical center from 2009 to 2019 were reviewed. Their composite disease activity scores at each follow-up point were collected. The therapeutic response between RA patients with SS (RA-SS) and without (RA-noSS) was compared. To correct confounders which may affect the therapeutic response, both propensity score matched and unmatched cohorts were analyzed by using the Cox proportional hazards model. RESULTS: Among the 1099 RA patients, 129 (11.7%) overlapped with SS were validated by positive anti-SSA or a minor salivary gland biopsy with histological changes suggestive of SS. After propensity score matching based on their baseline characteristics, 126 of 129 RA-SS and 126 of 970 RA-noSS patients were statistically extracted. Overlapping SS was associated with a 29%, 26%, 18%, and 22% lower probability of reaching remission defined by DAS28-ESR, DAS28-CRP, SDAI, and CDAI in RA patients, respectively. Similar decreased probability of reaching low disease activity was also observed. Although ESR was most significantly affected (HR 0.69, 95% CI 0.61-0.79), other component of composite RA disease activity score was also affected by overlapping SS. Stratification by age, RF/ACPA status, or baseline DAS28-CRP was not associated with change of results. CONCLUSIONS: Overlapping SS is associated with lower probability of reaching remission or low disease activity in RA patients and should be regarded as one of the poor prognostic factors. | |
33021334 | Six-month flare risk after discontinuing long-term methotrexate treatment in patients havi | 2020 Aug | OBJECTIVES: We investigated the disease flare rate in patients with rheumatoid arthritis (RA) who achieved low disease activity following long-term methotrexate (MTX) treatment and the factors related to flare. METHODS: This retrospective longitudinal cohort study included patients with RA and low disease activity who were exposed to MTX for >10 years. Disease flare was defined as an increase in Disease Activity Score of 28 joints (DAS28) of >1.2 within 6 months of discontinuation of MTX. Logistic regression analysis was performed to identify the factors associated with flare. RESULTS: In total, 97 patients with RA were included in the study. The mean baseline DAS28 was 1.96 ± 0.56. The median cumulative MTX dose was 11.7 g; the median duration of exposure to MTX was 19 years. Following MTX discontinuation, flare occurred in 43 (44.3%) patients; the median time to flare was 99 (28-168) days. According to univariate logistic regression analysis, C-reactive protein, erythrocyte sedimentation rate (ESR) at discontinuation, the average ESR in the 6 months before discontinuation of MTX, a weekly dose of MTX before discontinuation, and use of other conventional synthetic disease-modifying antirheumatic drugs were associated with a higher risk of disease flare. In multivariable analysis, a weekly dose of MTX before discontinuation (odds ratio 1.014; 95% CI 1.014-1.342; P = .031) was significantly associated with flare risk. CONCLUSION: Among patients with RA who achieved low disease activity with long-term treatment with MTX, more than half remained flare free after MTX discontinuation. A higher MTX dose before discontinuation was associated with a high flare risk. | |
32669099 | Effectiveness of preemptive antifibrinolysis with tranexamic acid in rheumatoid arthritis | 2020 Jul 15 | BACKGROUND: Patients with rheumatoid arthritis (RA) who have undergone total knee arthroplasty are at increased risk of requiring a blood transfusion. This study is designed to compare the effects of preemptive antifibrinolysis of single-dose and repeat-dose tranexamic acid (TXA) in in RA patients undergoing total knee arthroplasty (TKA). METHODS/DESIGN: The study will be a double-blind randomized controlled trial with two parallel groups of RA patients. Group A will be given 100 ml normal saline twice daily starting from 3 days before the operation, Group B will be given TXA 1.5 g twice daily starting from 3 days before the operation. All patients will be given TXA 1.5 g 30 min before the operation. The primary outcomes will be evaluated with total blood loss and hidden blood loss. Other outcome measurements such as, fibrinolysis parameters, inflammatory factors, visual analogue scale for post-operative pain, analgesia usage, coagulation parameters, transfusion, the length of stay (LOS), total hospitalization costs, the incidence of thromboembolic events and other complications will be recorded and compared. Recruitment is scheduled to begin on 1 August 2020, and the study will continue until 31 May 2021. DISCUSSION: In current literature there is a lack of evidence with regard to the efficacy of TXA in RA patients. The findings of this study, whether positive or negative, will contribute to the formulation of further recommendations on the use of TXA in RA patients undergoing TKA. TRIAL REGISTRATION: Chinese Clinical Trial Registry, ChiCTR2000029720 . Registered 14 February 2020. | |
32418036 | Periarticular osteophyte formation protects against total knee arthroplasty in rheumatoid | 2020 Nov | OBJECTIVE: Periarticular osteophyte formation is observed during the repair of damaged joints in rheumatoid arthritis (RA); however, little is known about its clinical and functional roles. This study aimed to determine the influence of periarticular osteophyte formation on the incidence of total knee arthroplasty (TKA) (a surrogate for long-term outcomes of joint destruction) in patients with RA. METHODS: This retrospective longitudinal study included a total of 130 symptomatic (tender and/or swollen) knee joints in 80 patients starting biologics. Cumulative incidences of TKA were compared according to the presence or absence of osteophyte on plain anteroposterior radiograph (osteophyte (±)) and the extent of advanced joint damage as defined by Larsen's grading system (0-II vs. III-V). RESULTS: Kaplan-Meier estimates showed a significantly lower cumulative incidence of TKA for the osteophyte (+) group (n = 33) compared with the osteophyte (-) group (n = 31) in the Larsen grades III-V group (38 vs. 74% at 10 years, P = 0.010), whereas no significant difference was observed between the osteophyte (+) (n = 11) and osteophyte (-) (n = 55) groups in the Larsen grades 0-II group (9 vs. 10% at 10 years). Multivariate Cox proportional hazards analysis revealed that older age (hazard ratio (HR), 1.04 per 1 year; 95% confidence interval (CI), 1.01-1.08) and osteophyte formation (HR, 0.39; 95% CI, 0.19-0.79) independently predicted TKA in the Larsen grades III-V group, whereas none of the assessed variables predicted TKA in the Larsen grades 0-II group. CONCLUSION: Osteophyte formation reduces the incidence of TKA in patients with RA who have advanced joint damage. Key Points • Older age and Larsen grade were independent predictors of total knee arthroplasty (TKA) in rheumatoid arthritis (RA) patients. • Periarticular osteophyte formation reduced the incidence of TKA in RA patients with Larsen grades III-V. | |
30836028 | Relationship of callosities of the forefoot with foot deformity, Health Assessment Questio | 2020 Mar | Objectives: We aimed to investigate the relationship of callosities of the forefoot with foot deformity, the Health Assessment Questionnaire Disability Index (HAQ-DI) and modified total Sharp score (TSS) in patients with rheumatoid arthritis (RA).Methods: A total of 202 patients and 404 feet were enrolled. We examined the prevalence of callosities. Clinical data included the HAQ-DI, TSS, hallux valgus angle (HVA), and calcaneal pitch angle (CPA). The analysis of factors associated with callosities of the forefoot was performed by comparing patients with and without callosities of the forefoot.Results: The prevalence of callosities was 31.2% of all patients and 24.0% of all feet. The patients with callosities of the forefoot had significantly higher TSS of the foot. The presence of callosities affected the HAQ-DI walking score. HVA and CPA were identified as being associated with callosities of the forefoot. Analyzing from the cutoff values, the odds ratios of HVA, CPA, and HVA and (combined) CPA were 4.64, 1.73, and 2.99, respectively.Conclusion: Hallux valgus and flatfoot were related to callosities of the forefoot in RA. This study suggested that to prevent callosities of the forefoot, early diagnosis and foot care for hallux valgus and flatfoot are needed in daily practice. | |
31746145 | Sociodemographic factors as determinants of disease, disability and quality of life trajec | 2020 Jan | OBJECTIVE: This study aims to describe the association between sociodemographic factors and trajectories of disease, disability and health-related quality of life (HRQoL) in early rheumatoid arthritis (ERA). METHODS: Data were collected prospectively over 3Â years in the Singapore Early Arthritis Cohort study. Trajectories were modeled using multi-trajectory group-based trajectory modeling (GBTM) and determinants of trajectory membership were identified using multinomial logistic regression. RESULTS: Two hundred and thirteen patients were included: 58.2% Chinese, 16.4% Malay, 21.6% Indian, mean (SD) age 51.3 (12.6) years and symptom duration 21.8 (15.3) weeks. In the multi-trajectory analysis, three groups of disease trajectories and corresponding disability and HRQoL trajectories were identified: group 1 (moderate disease rapid response, 49.9%), group 2 (high disease rapid response, 31.1%) and group 3 (high disease slow response, 19.1%). Malay patients had higher relative risk ratio (RRR) of being in trajectory groups 2 and 3 compared to group 1 (RRRÂ =Â 2.30, 95% CI 1.05-3.98 and RRRÂ =Â 4.02, 95% CI 1.45-6.43, respectively) while patients with tertiary education had lower relative risk (RRRÂ =Â 0.56, 95% CI 0.45-0.89 and RRRÂ =Â 0.33, (95% CI 0.14-0.83, respectively). In the analysis of individual outcomes, ethnicity, education level and body mass index were determinants of the heterogeneous disease activity trajectories. Gender and education level were determinants of the disability trajectories. Only gender was a determinant of the HRQoL trajectories. Further, 96.2% of the patients were treated with conventional synthetic disease-modifying antirheumatic drugs. CONCLUSION: Disparities in sociodemographic factors should be taken into consideration in formulating treatment strategies in ERA. | |
32472302 | Autoantibodies against a novel citrullinated fibrinogen peptide related to smoking status, | 2020 Nov | Treatment recommendations of early rheumatoid arthritis (RA) suggest differential management of patients on the basis of prognostic factors. In this study we aimed to investigate the relationship between autoantibodies against a novel citrullinated fibrinogen peptide (anti-CFP), smoking status, clinical activity and therapeutic response in Cuban patients with early RA, receiving treatment with methotrexate in comparison to rheumatoid factor (RF), anti-cyclic citrullinated peptide of second generation (anti-CCP2) and anti-mutated citrullinated vimentin (anti-MCV). A 6-month prospective observational study was performed in 60 early RA patients at baseline and 6 months after receiving methotrexate. Baseline and outcome measures included disease activity score of 28 joints (DAS 28), simplified disease activity index (SDAI), anti-CFP antibodies, RF, anti-CCP2 and anti-MCV. Therapeutic response was determined using 20/50/70 American College of Rheumatology (ACR) response rates. DAS28 (p < 0.0001), SDAI (p < 0.0001) as well as titres of anti-CFP (p = 0.0481), anti-CCP2 (p = 0.0082), RF IgM (p = 0.0187) and RF IgA (p = 0.0252) decreased under therapy. Multivariate analyses showed association of final anti-CFP values with sex and smoking status (p = 0.0296). It is of note that anti-CFP antibodies were one of predictors for DAS 28 (p = 0.0072) SDAI (p < 0.0001) and ACR response (p = 0.0003) in multivariate models. Anti-CFP antibodies decrease in correspondence with clinical improvement after 6-month therapy and are associated with sex and smoking status. Moreover, baseline anti-CFP antibodies, using in combination with sex, smoking status and autoantibodies (anti-CCP2, anti-MCV or RF) seems to have clinical relevance for predicting clinical activity and therapeutic response. | |
32856532 | Anti-cyclic citrullinated peptide antibodies are associated with radiographic damage but n | 2020 Nov | Objective: The discovery of anti-citrullinated protein antibodies (ACPAs) and the introduction of new therapeutic options have had profound impacts on early rheumatoid arthritis (RA) care. Since ACPA status, most widely assessed as reactivity to cyclic citrullinated peptides (CCPs), influences treatment decisions in early RA, we aimed to determine whether anti-CCP remains a predictor of disease activity and radiographic joint damage in more recent 'real-world' early RA. Method: Two observational early RA cohorts from Sweden enrolled patients in 1996-1999 (TIRA-1, n =Â 239) and 2006-2009 (TIRA-2, n =Â 444). Clinical and radiographic data and ongoing treatment were prospectively collected up to 3Â years. Two other cohorts served as confirmation cohorts (TRAM-1, with enrolment 1996-2000, n =Â 249; and TRAM-2, 2006-2011, n =Â 528). Baseline anti-CCP status was related to disease activity, pharmacotherapy, and radiographic joint damage according to Larsen score. Results: In the TIRA-1 cohort, anti-CCP-positive patients had significantly higher 28-joint Disease Activity Score, swollen joint count, C-reactive protein level, and erythrocyte sedimentation rate during follow-up compared with anti-CCP-negative patients. In TIRA-2, no such differences were found, but baseline anti-CCP positivity was associated with higher 3 year Larsen score (5.4 vs 3.5, p =Â 0.039). In TRAM-2, anti-CCP also predicted radiographic damage (8.9 vs 6.7, p =Â 0.027), with no significant differences in disease activity. Conclusion: In the early RA cohorts recruiting patients in 2006-2011, baseline anti-CCP positivity was not associated with disease activity over time, but was associated with increased radiographic damage at follow-up. Hence, close radiographic monitoring is warranted in early anti-CCP-positive RA regardless of disease activity. | |
31612755 | The periodontal inflamed surface area is associated with the clinical response to biologic | 2020 Nov | Objectives: We evaluated whether the periodontal inflamed surface area (PISA), a measure of the inflammatory burden posed by periodontitis, is associated with the clinical response to biological disease-modifying antirheumatic drugs (bDMARDs) in patients with rheumatoid arthritis (RA).Methods: We conducted a retrospective study that collected rheumatologic and periodontal data from 54 patients with RA who had received corticosteroid, conventional synthetic DMARDs, or non-steroidal anti-inflammatory drugs before (baseline) and after 6 months of bDMARD therapy. After the patients were divided into two groups based on high or low PISA according to the median measurements at baseline, the rheumatologic condition was compared between the groups.Results: The patients with a low PISA showed significantly lower values for the Clinical Disease Activity Index (CDAI) (p = .008), swollen joint count (p = .02), and patient's and evaluator's global assessment (p = .01 and p = .03) and significantly greater decreases in changes in the CDAI from baseline to 6 months than the patients with a high PISA (p = .01), although these values were comparable at baseline. Both univariate and multivariate analyses revealed a significantly positive correlation between the baseline PISA and changes in the CDAI (p = .04 and p < .001).Conclusion: The PISA is associated with the clinical response to bDMARDs in patients with RA. | |
32280208 | Association of Chinese Herbal Medicines Use with Development of Chronic Obstructive Pulmon | 2020 | PURPOSE: Rheumatoid arthritis (RA) patients appear to report a higher risk of chronic obstructive pulmonary disease (COPD). While Chinese herbal medicine (CHMs) is proven to lower COPD risk, the scientific evidence regarding its effect in relation to COPD onset among them is limited. This longitudinal cohort study aimed to determine the relationship between CHMs use and the COPD risk in RA patients. METHODS: Using the nationwide claim data, 8349 patients newly diagnosed with RA and simultaneously free of COPD between 1998 and 2010 were eligible for enrollment. From this sample, we enrolled 3360 CHMs users and 3360 non-CHMs users, randomly selected using propensity scores matching from the remaining cases. They were followed until the end of 2012 to record COPD incidence. The hazard ratio (HR) of COPD with regard to CHMs use was estimated by the Cox proportional hazards regression model. RESULTS: In the follow-up period, 136 CHMs users and 202 non-CHMs users developed COPD, representing incidence rates of 5.16 and 7.66, respectively, per 1000 person-years. CHMs use was associated with a 32% lower subsequent risk of COPD (adjusted HR: 0.68, 95% Confidence Interval: 0.54-0.84). Eight commonly prescribed CHMs were discovered to be associated with lower COPD risk: Yan Hu Suo, SÄnÉ¡ ZhÄ«, Dang Shen, Huang Qin, Jia-Wei-Xiao-Yao-San, Shu-Jing-Huo-Xue-Tang, Du-Huo-Ji-Sheng-Tang and Ge-Gen-Tang. CONCLUSION: A significant association of CHMs use with a lower risk of COPD onset in RA patients was found, suggesting that CHMs could be integrated into conventional therapy to reduce COPD risk. | |
33025891 | Compromised ultrasound remission, functional ability and clinical decision associated with | 2020 Jul | OBJECTIVES: Rheumatoid arthritis (RA) patients with Sjögren's syndrome (SS) often present with more severe synovitis. We intended to clarify the impact of overlapping SS on ultrasound remission, functional ability and clinical decision-making in RA patients in a real-world cohort from 2009 to 2019. METHODS: The medical records of RA patients in our medical centre from 2009 to 2019 were reviewed. Cox proportional hazards models of ultrasound remission and no disability (by health assessment questionnaire [HAQ]) were conducted in both the 1-to-1 nearest propensity score matched (PSM) and unmatched cohorts between RA patients with SS (RA-SS) and without (RA-noSS) to correct critical confounders. Four kinds of PSM methods were used and the corresponding average treatment effect on the treated (ATT) was calculated to clarify the effect of overlapping SS on distinguishable characteristics or drug prescription in RA patients. RESULTS: A total of 1100 RA patients were included in the study, of which 133 (12.1%) overlapped with SS. Among 256 patients consisting of 128 RA-SS and 128 RA-noSS after 1-to-1 nearest PSM, overlapping SS was associated with a 44%, 32% lower probability of reaching ultrasound remission, no disability in RA patients, respectively. More hydroxychloroquine (HCQ) usage, less biologic disease-modifying anti-rheumatic drugs (bDMARDs) prescription were confirmed to be correlated with overlapping SS by the robust PSM. CONCLUSIONS: Overlapping SS is associated with a lower probability of reaching ultrasound remission and no disability in RA patients. HCQ may still be the mainstream of clinical decision making in RA-SS patients. | |
32118795 | Association between biologic disease modifying anti-rheumatic drugs and incident hypertens | 2020 Feb | There has been some debate between biologic disease modifying anti-rheumatic drugs (bDMARDs) treatment and hypertension (HTN) in rheumatoid arthritis (RA). The aim of this study was to determine the effect of bDMARDs on the development of HTN in patients with RA.A total of 996 patients eligible for analysis were recruited from the Korean College of Rheumatology Biologics & Targeted Therapy (KOBIO) registry from 2012 to 2018. The bDMARDs were tumor necrosis factor (TNF) inhibitors, abatacept, and tocilizumab. The cDMARDs included methotrexate, hydroxychloroquine, and leflunomide. The incidence rate and 95% confidence interval of HTN were estimated using the Kaplan-Meier method. Hazard ratio (HR) of risk factors associated with hypertension was assessed by cox proportional hazard model analysis.Among the 996 patients, 62 patients (6.2%) were newly diagnosed with HTN. There were differences in incidence rate of HTN among conventional DMARDs (cDMARDs), TNF inhibitors, tocilizumab, and abatacept during the follow-up period (P = .015). Kaplan-Meier analysis showed that there was a significant difference in incident HTN only between cDMARDs and tocilizumab (P = .001). Systolic blood pressure and positive rheumatoid factor were associated with development of HTN (HR = 1.049, P = .016 and HR = 1.386, P = .010, respectively). Cox proportional hazard model analysis showed no difference in the development of HTN between bDMARDs and cDMARDs in RA.This study showed that bDMARDs treatment might not increase risk of incident HTN in patients with RA, compared to cDMARDs. | |
32009356 | Low Vitamin D Levels in Rheumatoid Arthritis Patient is Associated with Poor Disability In | 2020 Feb | BACKGROUND: Rheumatoid arthritis (RA) is a chronic inflammatory connective tissue disorder with wide spectrum of presentation from polyarthritis to multisystem involvement. Apart from bones, muscles and other soft tissues, Vitamin D receptors have been found on many immune cells and tissues. The most vital function of Vitamin D is calcium and phosphorus absorption but it can also act as an immune-modulator hormone, which can affects both innate and adaptive immune responses leading to autoimmune diseases. OBJECTIVES: To study the relationship of vitamin D insufficiency with disease activity and functional disability in patients of Rheumatoid Arthritis. MATERIAL AND METHODS: The present study was an observational, cross sectional study done in a tertiary care hospital in New Delhi, India. The inclusion criteria comprised of patients attending the inpatient (IPD) and outpatient department (OPD), age above 18 years and fulfilling 1987 American college of Rheumatology (ACR) criteria for RA. The exclusion criteria was patients suffering from any other connective tissue disorder (CTD) and patients who were taking vitamin D supplements for past 6 months. Thirty patients were enrolled in the study after satisfying inclusion and exclusion criteria and appropriate clinical data and blood sample were collected after informed consent. Joint examination were performed and swollen joint count (SJC), tender joint count (TJC), patient global assessment (PGA) and evaluator global assessment (EGA) scores were recorded. Disease activity using DAS28ESR, DAS28CRP and CDAI were calculated and disability index was assessed using Short Fries Health Assessment Questionnaire. RESULTS: In our study mean vitamin D level was 18.93 ng/ml (S.D. 6.64 ng/ml). Mean DAS28 ESR was 4.57±1.48. Mean Disability Index was 0.52±0.89. All the study population had low Vitamin D level (100%), while 50% patients had vitamin D level in deficiency range (<20ng/ml). On analysis by student t-test, statistically higher PGA (p value 0.024) and Disability Index (p value < 0.001) in vitamin D deficient patients, compared to vitamin D insufficient patient group was observed, however there was no significant difference in disease activity between the groups. CONCLUSION: Low Vitamin D levels are common in Indian rheumatoid arthritis patients. Mean PGA significantly increased, and disability index significantly increased in Vitamin D deficient group compared to insufficient group suggesting vitamin D deficient patients poor wellbeing and more disability. |
