34916677 [Clinical characteristics and risk factors of rheumatoid arthritis with ulcerative keratit 2021 Dec 18 OBJECTIVE: To investigate the clinical characteristics, risk factors and prognosis of ulcerative keratitis (UK) in patients with rheumatoid arthritis (RA). METHODS: Sixteen patients with UK (the UK group) were screened among 4 773 RA patients hospitalized at Peking University People's Hospital from January 2003 to May 2021, and 72 patients with RA without UK in the control group were selected by propensity score matching (PSM). The clinical features, laboratory data and medications between the two groups were collected and analyzed. RESULTS: The average age of the patients with RA was 60 years at the time of the complication of UK. UK appeared on average in the 16th year of RA, with the majority of UK occurring in the 7th year of RA and beyond (14 cases), however, a minority of UK was the first symptom of RA (1 case). UK associated with RA manifested as simple marginal UK in 8 cases, marginal UK with perforation in 5 cases, marginal UK with uveitis in 2 cases and central UK with perforation in 1 case. The number of swollen joints was significantly higher in the UK group than in the control group [6.0(2.5, 23.0) vs. 3.0(1.0, 9.8), Z=-2.047, P=0.041], and the proportion of secondary Sjögren syndrome (SS, 37.5% vs. 6.9%, χ(2)=11.175, P=0.004) and interstitial lung disease (ILD, 37.5% vs. 8.3%, χ(2)=9.456, P=0.008) were significantly higher in the RA patients with UK than the patients without UK. The uses of sulfasalazine (12.5% vs. 48.6%, χ(2)=7.006, P=0.008), leflunomide (31.3% vs. 63.9%, χ(2)=5.723, P=0.017) and gold salt(6.3% vs. 33.8%, χ(2)=4.841, P=0.032)were significantly lower in the UK group than in the control group. However, there was no statistically significant comparison between the two groups for the 28-joint disease activity score-erythrocyte sedimentation rate (5.3±1.8 vs. 5.1±1.6, t=0.309, P=0.761). Logistic analysis showed the number of swollen joints (OR=1.148), secondary SS (OR=79.118), complicated with ILD (OR=6.596) and the use of sulfasalazine (OR=0.037) were independent relevant factors (P < 0.05) for UK in RA patients. CONCLUSION: The number of swollen joints, secondary SS, complicated with ILD and the use of sulfasalazine are independent relevant factors for UK in patients with RA.
32475025 Prevalence of Rheumatoid Arthritis and Drug Dispensing Patterns Among Medicaid and Medicai 2021 Feb OBJECTIVE: To estimate the prevalence of rheumatoid arthritis (RA) in Puerto Rico, to describe disease-modifying antirheumatic drug (DMARD) dispensing patterns by prescriber specialty, and to illustrate the impact of RA case definition on the estimated prevalence. METHODS: This study estimated the prevalence of RA in Puerto Rico during 2016 among Medicaid and Medicaid-Medicare dually eligible beneficiaries of the Mi Salud health care plan, a federally funded health insurance program. DMARD dispensing and cost patterns were described and stratified by provider specialty. A sensitivity analysis was conducted to evaluate the effect of RA case definition on estimated prevalence. RESULTS: The prevalence of RA in 2016 was estimated to be 2 cases per 1,000 beneficiaries, with 3 per 1,000 beneficiaries among females, 4.5 times that of males. In total, 44% of beneficiaries received conventional synthetic DMARDs (csDMARDs) only, 32% received biologic or targeted synthetic DMARDs (b/tsDMARDs) only, and 24% received a combination of csDMARDs and b/tsDMARDs. Rheumatologists and a combination of specialties accounted for the highest median number of dispensed DMARDs, with 14 each. A sensitivity analysis revealed that when RA cases with ≥3 medical claims were restricted to having ≥1 DMARD claim, the estimated prevalence changed from 6 to 3 cases per 1,000 beneficiaries. CONCLUSION: The prevalence of RA in Puerto Rico in this study is lower than reported in the mainland US, possibly due to more stringent criteria to define RA. DMARD dispensing and cost patterns are similar to those found in other studies. Claims algorithms that identify RA have higher validity when pharmacy data is included.
33360226 Beta-2-glycoprotein-I IgA antibodies predict coronary plaque progression in rheumatoid art 2021 Feb OBJECTIVES: To evaluate whether anti-Beta-2-Glycoprotein-I (anti-β2GPI) IgA antibodies associate with progression of coronary atherosclerosis and cardiovascular disease (CVD) events in rheumatoid arthritis (RA). METHODS: One hundred-fifty patients underwent plaque evaluation (total, non-calcified, mixed and calcified) with coronary computed tomography angiography; 101 were re-imaged within 6.9±0.3 years to assess progression. The Framingham-D'Agostino score assessed cardiovascular risk. Coronary artery calcium (CAC) and segment involvement score quantified plaque burden. RESULTS: Anti-β2GPI IgA were seen in 45 (30%) patients. Despite no link to baseline plaque burden, anti-β2GPI IgA associated with segment involvement score increase (adjusted-RR=1.64 [95%CI 1.02-2.63]), CAC change (adjusted-β=0.33 [95%CI 0.002-0.656]) and developing new extensive or obstructive plaque at follow-up (adjusted-OR=4.24 [95%CI 1.30-13.87]). Adding anti-β2GPI IgA to logistic regression models with conventional risk factors predicting plaque progression outcomes increased Area under the receiver-operator curve and improved Net Reclassification and Integrated Discrimination Improvement indices (all P<0.05). In per-segment analyses, anti-β2GPI IgA predicted mixed plaque formation (adjusted-OR=3.20 [95%CI 1.01-10.09]) and lower likelihood of transition of mixed to calcified plaque (adjusted-OR=0.19 [95%CI 0.04-0.96]). Anti-β2GPI IgA moderated the effect of C-reactive protein on CAC change such that C-reactive protein associated with CAC change (β=0.26 [95%CI 0.14-0.38]) and CVD risk (adjusted-HR=1.89 [95%CI 1.02-3.51]) only in anti-β2GPI IgA positive patients. CONCLUSION: Anti-β2GPI IgA addition to clinical risk models improved prediction accuracy of CAC, plaque progression and transition to extensive/obstructive disease. They associated with new high-risk mixed plaques and delayed healing to calcified lesions. Anti-β2GPI IgA further modified the effect of inflammation on plaque progression and CVD events.
33741141 Association Between the Extent of Periodontal Inflammation and the Severity of Rheumatoid 2021 Oct OBJECTIVE: Periodontal inflammation can affect the progression of rheumatoid arthritis (RA), and RA drugs may influence the periodontal condition of patients with RA. We examined whether the association between periodontal inflammation and the severity of RA is influenced by RA medication. METHODS: This cross-sectional study recruited 98 Japanese patients with RA from an orthopaedic clinic. We assessed the severity of RA using the Steinbrocker class and stage. The periodontal inflamed surface area (PISA) was used as an indicator of periodontal status. We obtained data on RA medications from medical records. We examined the associations among periodontal tissue inflammation, RA medications, and RA severity using multinomial logistic regression analyses. RESULTS: In univariate multinomial logistic regression analyses, no significant association between PISA score and RA severity was observed. There was no significant association between PISA score and RA severity in multivariate analyses not including variables about RA drugs as independent variables. However, in multivariate analyses adjusted for RA drugs and other confounding variables, patients with a PISA >550 mm(2) had significantly higher odds ratios (ORs) for Steinbrocker class III-IV and stage III-IV (OR, 20.24; 95% confidence interval [CI], 1.78-229.85 and OR, 12.42; 95% CI, 1.79-86.49, respectively) compared to patients with PISA score ≤550 mm(2). CONCLUSION: The extent of periodontal inflammation is associated with the severity of RA independent of RA medications.
34189674 Factors associated with COVID-19 and its outcome in patients with rheumatoid arthritis. 2021 Nov OBJECTIVE: We assessed the factors associated with COVID-19, clinical manifestations, and a 30-day-prognosis of COVID-19 in a cohort of rheumatoid arthritis (RA) patients compared with the index population. METHODS: In a cross-sectional study, RA patients were followed in rheumatology clinics of Tabriz University of Medical Sciences, and a group of patients diagnosed with COVID-19 from index population were recruited. Outcomes of COVID-19 were assessed by the hospitalization rate and need to intensive care unit (ICU) and mortality. During a period of 12 weeks, 128 RA patients diagnosed with COVID-19, 760 RA control group, and 92 COVID-19 patients from index population were enrolled. RESULTS: Being female, obese, and diabetic, having pulmonary disease and chronic kidney disease (CKD), and treatment with prednisolone > 5 mg/d and TNFα inhibitors (TNFis) were independent predictors of COVID-19 in RA patients. Dyspnea, anosmia, and taste loss were more common in RA patients compared with the index population. Admission in hospital, need to ICU care, and mortality occurred in 38, 11.9, and 8.6 percent of RA patients, respectively. Although hospitalization rate in RA patients was more than the index population, there were no significant differences in need to ICU care and mortality between the two groups. CONCLUSIONS: Treatment with prednisolone and TNFis and having comorbidities including obesity, diabetes, pulmonary disease, and CKD increase the risk of COVID-19 in RA patients. Although some differences exist in the clinical manifestations of COVID-19 in RA patients and index population, prognosis of COVID-19 in RA patients is not any worse. Key Points • Being female, obese and diabetic, having pulmonary disease, chronic kidney disease (CKD), treatment with prednisolone > 5 mg/d and TNFα inhibitors (TNFis) were independent predictors of COVID-19 in RA patients. • Dyspnea, anosmia and taste loss were more common in RA patients compared with the index population. • Although COVID-19 related hospitalization was higher in RA patients than in the index population, there was no significant differences in the need to ICU care and mortality between the two groups.
31876844 Role of Interleukin 6 Inhibitors in the Management of Rheumatoid Arthritis. 2021 Dec 1 Rheumatoid arthritis (RA) is a multisystem disease that affects the joints and various organs, resulting in compromised quality of life and increased mortality. A wide spectrum of treatment options is available for RA. Conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) are the first-line of treatment for RA, whereas tumor necrosis factor α inhibitors are commonly used as a second-line biological disease-modifying antirheumatic drug following inadequate response to csDMARDs. However, remission remains difficult to achieve. No single agent is effective for all patients. It is important to consider patients' comorbidities, perspectives, and preferences when selecting treatment.Interleukin 6 (IL-6) plays a prominent role in the pathophysiology of RA and is an important therapeutic target for RA. Tocilizumab and sarilumab are approved IL-6 inhibitors, which have demonstrated good efficacy and tolerability as combination therapy or monotherapy in RA patients with inadequate response to csDMARDs or tumor necrosis factor α inhibitors. Apart from alleviating joint symptoms, inducing remission, and reducing structural damage, tocilizumab and sarilumab exhibit additional advantages in alleviating extra-articular symptoms, such as fatigue and morning stiffness, and have positive effect on anemia and glucose metabolism. Additionally, evidence showed that certain patient subgroups, such as those with comorbidities including anemia and diabetes mellitus, those with early RA, those with high baseline IL-6 levels, those at high risk of tuberculosis infection, or those intolerant to methotrexate monotherapy, may benefit from IL-6 inhibition. Given these advantages, tocilizumab and sarilumab can be considered earlier as a rational choice for treating RA in suitable patients. Future clinical investigations will help refine the use of these agents.
32939570 The risk of leukemia in patients with rheumatoid arthritis: a systematic review and meta-a 2021 Apr OBJECTIVES: The relationship between rheumatoid arthritis (RA) and the risk of leukemia was still controversial. This study aimed to assess the risk of leukemia in patients with rheumatoid arthritis by systematic review and meta-analysis. METHODS: Relevant studies were identified by searching PubMed, Embase, Cochrane Library, and SinoMed up to December 2019. Random effects model analysis was used to pool standardized incidence ratios (SIRs) and 95% confidence interval. RESULTS: A total of 15 relevant studies that met the criteria were included. Compared with the general population, patients with RA showed an increased risk of leukemia (SIR = 1.51, 95% CI: 1.34-1.70). The statistical heterogeneity was moderate with an I(2) of 55.5%. In subgroup analysis, the source of heterogeneity may be due to differences in sample size. Publication bias was not found in the Begg funnel plot and the Egger test. CONCLUSION: Our findings suggested that the risk of leukemia in RA was increased compared with the general population. Key points • This is the first systematic review and meta-analysis to assess the risk of leukemia in RA. • Our study suggested that the risk of leukemia in RA was increased compared with the general population. • This study indicated that the risk of leukemia in RA was higher in non-Asian populations.
34825948 [Use of biosimilars in the treatment of rheumatoid arthritis : An overview]. 2022 Mar Biologics have been an integral part of the treatment of rheumatoid arthritis for approximately 20 years. As patents for pharmaceuticals generally expire after 10 years, in recent years biosimilars have come onto the market. Many studies have shown that they are an equivalent alternative to the reference drug with comparable safety and efficacy. In some cases, they even showed lower rates of adverse drug reactions compared to the reference drugs. Furthermore, considerable costs can be saved by biosimilars, which amount to an annual three-digit million sum in Germany alone. Large regional differences in the prescription frequency of biosimilars in Germany can be identified, which are also reflected in the savings potential. A switch to a biosimilar is possible and desirable with the involvement of the patient. In this sense, the initial prescription of a biosimilar instead of the reference drug is also to be advocated.
33599738 Network meta-analysis of infliximab biosimilars for the treatment of rheumatoid arthritis. 2021 Mar 31 PURPOSE: This article assesses the relative efficacy and safety of infliximab biosimilars in treatment of patients with rheumatoid arthritis (RA). METHODS: A frequentist, random-effects network meta-analysis was performed to evaluate evidence from randomized controlled trials that examined the use of infliximab biosimilars for treatment of patients with RA. PubMed/MEDLINE and other sources were searched for reports evaluating rates of response to treatment with the reference product (infliximab) vs an infliximab biosimilar. The primary efficacy outcome of interest was the rate of attainment of ACR20 (ie, 20% improvement in American College of Rheumatology core measures). The primary safety outcome was the rate of treatment-related serious adverse events (SAEs). Data were extracted by the primary author, and an assessment for risks of methodological bias was performed for each evaluated study. RESULTS: Five studies that enrolled a total of 2,499 patients were included. Overall comparisons using odds ratios and 95% confidence intervals (CIs) did not indicate statistically significant differences in response to treatment with biosimilar agents relative to each other or the infliximab reference product. ORs for ACR20 response for biosimilars vs infliximab were as follows: 1.475 (95% CI, 0.940-2.315) for infliximab-axxq, 1.259 (95% CI, 0.854-1.855) for infliximab-dyyb, 0.865 (95% CI, 0.5511.358) for infliximab-qbtx, and 0.832 (95% CI, 0.506-1.367) for infliximab-abda. Similar findings were observed in reported SAE rates among patients treated with the various biosimilars. CONCLUSION: ACR20 response appears to be comparable and nonsignificantly different between infliximab biosimilars. In the absence of any meaningful differences in safety or efficacy, biosimilar cost may be the deciding factor in choosing a treatment or agent for formulary inclusion.
33387966 Association of interleukin-17 gene polymorphisms with the onset of Rheumatoid Arthritis. 2021 Jan Rheumatoid Arthritis (RA) is an autoimmune disorder where multiple cytokines including IL-17A and IL-17F produced by T helper cell 17 (Th17), contribute to its pathogenesis. By initiating inflammatory responses in joints Th17 act as pathogenic driver leading to bone and cartilage destruction in RA patients. Hence, the planned study was aimed to estimate IL-17 gene polymorphism association with RA susceptibility in Pakistani population. The present study included 100 subjects (50 RA patients and 50 healthy controls). Blood samples were taken and DNA was isolated for genotyping purpose. Chi square and Logistic regression analysis was performed to check the association of selected SNPs with RA. For rs2397084 and rs763780 polymorphism T allele acted as significant risk factor as compared to the reference C allele. TT vs. CC comparison in rs2397084 showed that T allele is a risk factor (OR 5.538; 95%Cl 1.757-17.458) in RA susceptibility. In case of rs763780 heterozygous CT (OR 10.80; 95% Cl 3.736-31.218) and homozygous mutant TT (OR 7.50; 95% Cl 2.360-23.831) genotypes proved to be a potential risk for RA patients. The significant differences in allelic and genotypic frequencies were observed for both SNPs. While for rs2275913 significantly varied frequency was observed only for dominant model of inheritance and non significant differences were seen at allelic level. Variation at all these three polymorphic sites substituted mutant amino acids leading to further functional changes in protein structure. Three polymorphic sites rs2275913, rs763780 and rs2397084 positioned on IL-17 gene were significantly strong factors in RA incidence among Pakistani population as they alter normal function of inflammatory cytokine IL-17.
34382756 Handling missing data in a rheumatoid arthritis registry using random forest approach. 2021 Oct Missing data in clinical epidemiological research violate the intention-to-treat principle, reduce the power of statistical analysis, and can introduce bias if the cause of missing data is related to a patient's response to treatment. Multiple imputation provides a solution to predict the values of missing data. The main objective of this study is to estimate and impute missing values in patient records. The data from the Kuwait Registry for Rheumatic Diseases was used to deal with missing values among patient records. A number of methods were implemented to deal with missing data; however, choosing the best imputation method was judged by the lowest root mean square error (RMSE). Among 1735 rheumatoid arthritis patients, we found missing values vary from 5% to 65.5% of the total observations. The results show that sequential random forest method can estimate these missing values with a high level of accuracy. The RMSE varied between 2.5 and 5.0. missForest had the lowest imputation error for both continuous and categorical variables under each missing data rate (10%, 20%, and 30%) and had the smallest prediction error difference when the models used the imputed laboratory values.
33184983 Autophagy Activation by Resveratrol Reduces Severity of Experimental Rheumatoid Arthritis. 2021 Jan SCOPE: Previous work reported that dietary supplementation with resveratrol lowers synovial hyperplasia, inflammatory and oxidative damage in an antigen-induced arthritis (AIA) model. Here, it is investigated whether resveratrol can regulate the abnormal synovial proliferation by inducing autophagy and controlling the associated inflammatory response. METHODS AND RESULTS: Animals treated with resveratrol 8 weeks before AIA induction show the highest significant signal for microtubule-associated protein 1 light chain 3 by confocal microscopy. Besides, resveratrol significantly reduces p62 expression, but it does not increase the signal of beclin-1. Also, active caspase-3 expression, as well as poly(ADP-ribose) polymerase, is upregulated in the AIA group, and is significantly reduced in resveratrol-treated AIA group. Resveratrol also mitigates angiopoietin-1 and vascular endothelial growth factor signals. Finally, resveratrol significantly reduces the serum levels of IL-1β, C reactive protein, and prostaglandin E2, as well as nuclear factor κB synovial tissue expression, which shows a significant correlation with p62 expression. CONCLUSION: Dietary supplementation with resveratrol induces the noncanonical autophagy pathway and limits the cross-talk with inflammation, which in consequence modulates the synovial hyperplasia. Preventive strategies that incorporate dietary intervention with resveratrol may offer a potential therapeutic alternative to drugs to influence the risk of rheumatoid arthritis and influence its course.
32023138 Decreased peripheral blood memory B cells are associated with the presence of interstitial 2021 Jan OBJECTIVES: Interstitial lung disease sometimes occurs in rheumatoid arthritis patients. Although the underlying immunological mechanisms responsible for interstitial lung disease associated with rheumatoid arthritis have not yet been clarified, some reports have suggested possible roles of B cells. To examine the role of B-cell subsets in interstitial lung disease in rheumatoid arthritis patients, we analyzed peripheral blood B-cell subsets. METHODS: We analyzed the frequencies of the peripheral blood B-cell subsets by flow cytometry in rheumatoid arthritis patients with and without interstitial lung disease (n = 16 and 81, respectively) and in healthy donors (n = 110) by high-resolution computed tomography. RESULTS: Compared with healthy donors, rheumatoid arthritis patients showed statistically higher frequencies of naive B cells and lower frequencies of memory B cells. Moreover, the frequencies of memory B cells were lower in rheumatoid arthritis patients with interstitial lung disease than in those without. Multivariate analysis showed that the frequency of memory B cells, particularly switched memory B cells, was significantly decreased in rheumatoid arthritis patients with interstitial lung disease, even after adjusting for prednisolone dose. CONCLUSIONS: We suspect memory B cells play important roles in interstitial lung disease associated with rheumatoid arthritis.
33792210 Effects of non-surgical periodontal treatment in rheumatoid arthritis patients: A randomiz 2021 Jan BACKGROUND: The periodontal condition has a reciprocal relationship with rheumatoid arthritis (RA). Rheumatoid arthritis patients are reported to present with more serious periodontal disease (PD) as compared to non-RA patients. OBJECTIVES: This study aimed to evaluate the effects of non-surgical periodontal treatment on Vietnamese patients with active RA and PD, where the clinical characteristics and serum indices of the patients were of interest. MATERIAL AND METHODS: We conducted a randomized clinical trial (RCT) on 82 RA patients with PD. The patients were randomly divided into 2 groups: the intervention group, consisting of patients who received oral hygiene instructions, scaling and root planing; and the control group, consisting of patients who received oral hygiene instructions only. Both groups received the same treatment plan for RA. The Disease Activity Score 28 based on C-reactive protein (DAS28-CRP), disease activity classification, rheumatoid factor (RF), erythrocyte sedimentation rate (ESR), anti-citrullinated protein autoantibodies (ACPAs), and C-reactive protein (CRP) were monitored, with the measurements taken at 3 months and 6 months following the treatment. RESULTS: The 2 groups exhibited similar parameters at baseline. In the intervention group, DAS28-CRP and disease activity classification were significantly reduced at 3 months after treatment as compared to the baseline data. At 6 months following the treatment there was a significant decrease in ESR, ACPAs and DAS28-CRP in the intervention group, while the control group showed a decrease only in ACPAs. Further, when comparing the intervention and control groups at 6 months following the treatment, there were no differences between the groups in the ACPAs, RF and CRP serum levels. CONCLUSIONS: Non-surgical periodontal treatment can significantly reduce DAS28-CRP, disease activity classification, ESR, and the ACPAs level in serum, and can be applied to reduce RA severity in RA patients with PD.
33795331 Tuberculosis in Biologic-naïve Patients With Rheumatoid Arthritis: Risk Factors and Tuber 2021 Aug OBJECTIVE: To investigate risk factors and characteristics of active tuberculosis (TB) in biologic-naïve patients with rheumatoid arthritis (RA). METHODS: We conducted a population-based case-control study using the Swedish Rheumatology Quality Register, the National Patient Register, and the Tuberculosis Register to identify RA patients with active TB and matched RA controls without TB between 2001-2014. Clinical data were obtained from medical records. TB risk was estimated as adjusted OR (aOR) with 95% CI using univariate and multivariable logistic regression analyses. RESULTS: After validation of diagnoses, the study included 31 RA patients with TB and 122 matched RA controls. All except 3 cases had reactivation of latent TB. Pulmonary TB was most prevalent (84%). Ever use of methotrexate was not associated with increased TB risk (aOR 0.8, 95% CI 0.3-2.0), whereas ever treatment with leflunomide (aOR 6.0, 95% CI 1.5-24.7), azathioprine (aOR 3.8, 95% CI 1.1-13.8), and prednisolone (PSL; aOR 2.4, 95% CI 1.0-6.0) was. There were no significant differences between maximum dose of PSL, treatment duration with PSL before TB, or cumulative dose of PSL the year before TB diagnosis between cases and controls. Obstructive pulmonary disease was associated with an increased TB risk (aOR 3.9, 95% CI 1.5-10.7). CONCLUSION: Several RA-associated factors may contribute to increased TB risk in biologic-naïve patients with RA, making the risk of TB activation difficult to predict in the individual patient. To further decrease TB in patients with RA, the results suggest that screening for latent TB should also be considered in biologic-naïve patients.
33087675 Possible Cerebral Vasculitis in a Case with Rheumatoid Arthritis. 2021 Mar 15 Cerebral rheumatoid vasculitis (CRV) is a rare, fatal, and diagnostically challenging disorder. We herein report an 81-year-old woman with a 4-year history of rheumatoid arthritis who presented with a fever, progressive disturbance of consciousness, high level of rheumatoid factor, and hypocomplementemia. The enhancement of the perforating branches in the left middle cerebral artery led us to suspect CRV. A brain biopsy could not be performed. After we intensified steroid therapy, the size of the cerebral lesions temporarily decreased. However, recurrence in the left frontal lobe occurred one month later, and the patient subsequently died. Early intensive treatments may be needed for CRV.
33966315 Rheumatoid meningitis: A systematic review and meta-analysis. 2021 Sep BACKGROUND AND PURPOSE: Rheumatoid meningitis (RM) is a neurological complication of rheumatoid arthritis (RA). Current evidence is based on case reports and partial reviews. METHODS: This is a systematic review and meta-analysis following the PRISMA statement. The aim is to describe the characteristics of the disease, including clinical, imaging and laboratory findings, treatment, outcomes and prognosis reported in the literature. RESULTS: In all, 103 studies with 130 cases were included. RM affected adults with an average age of 62 years, with or without a previous RA diagnosis. RA activity and time with the disease were associated with a worse prognosis. Most common clinical manifestations were transient focal neurological signs (64.6%), systemic symptoms (51.3%), episodic headache (50.4%) and neuropsychiatric alterations (47.7%). Joint manifestations were present in only 27.4% of cases. Brain magnetic resonance imaging showed unilateral or bilateral involvement, predominantly frontoparietal. Both pachymeninges and leptomeninges were affected, the latter more frequently (82.88%). The laboratory findings included increased levels of rheumatoid factor (89.71%), anti-cyclic citrullinated peptide (89.47%), C-reactive protein (82.54%) and erythrocyte sedimentation rate (81.81%). Cerebrospinal fluid analysis showed an increase in the protein level (76.14%), with pleocytosis (85.19%) of mononuclear predominance (89.19%). Biopsy was performed in 72.52% of the patients. Corticosteroid pulse therapy was the main induction therapy. Disease relapse occurred in 31.17% of patients, whilst 54.54% had a full recovery. CONCLUSIONS: Rheumatoid meningitis must be considered in adult patients with or without RA diagnosis, high-dose corticosteroid induction therapy should be installed and maintenance therapy plays a key role. It is not recommended to use anti-TNF as an induction therapy. Nowadays, RM has a significantly better outcome. These findings may aid clinicians in timely RM diagnosis and treatment, thus improving its outcomes.
33128201 Epidemiology and Treatment of Patients with Rheumatoid Arthritis, Psoriatic Arthritis and 2021 Jan INTRODUCTION: Rheumatoid arthritis (RA), psoriatic arthritis (PsA) and psoriasis (PSO) are chronic inflammatory diseases that have a substantial impact on patients' health. This retrospective database study aimed to assess the epidemiology, comorbidities, diagnosis and treatment patterns of RA, PsA and PSO in the German population. METHODS: Data were extracted from the Deutsche Forschungsdatenbank für Abrechnungsinformationen der Krankenversicherung database from 2012 to 2016 for patients aged ≥ 18 years holding full health coverage in the reporting year at least. Diagnoses were defined according to International Classification of Diseases (ICD)-10 codes. Reported outcomes included prevalence and incidence rates, pre-defined comorbidities, diagnosing and treating physicians, and treatment exposure. A subgroup analysis was performed for women of childbearing age (females aged 18-45 years). RESULTS: The prevalence rates of RA, PsA and PSO in Germany were consistent over the study period; by 2016 they were 0.4%, 0.3% and 2.1%, respectively, and in women of childbearing age they were 0.2%, 0.2% and 1.5%, respectively. RA, PsA and PSO were predominantly observed among patients aged > 45 years. RA and PsA were more prevalent in women, while PSO had an approximately equal gender distribution. Depressive episodes were the most frequently reported comorbidity in 2016 (RA: 25.7%; PsA: 25.1%; PSO: 17.8%), and this was similar in women of childbearing age (RA: 20.5%; PsA: 23.4%; PSO: 16.3%). Approximately 50% of patients with RA and PsA and 6% of patients with PSO were receiving systemic treatment in 2016, of which methotrexate (RA: 38.4%; PsA: 30.2%; PSO: 2.2%) was most common. Biologic therapies were the least frequently used treatment options (RA: 28.9%; PsA: 20.9%; PSO: 1.8%). CONCLUSIONS: This analysis provides key epidemiological information for patients with RA, PsA and PSO, including in women of childbearing age, in Germany and highlights common comorbidities and that patients were likely receiving insufficient treatment for these diagnoses.
32557446 [Interprofessional Care of Patients with Rheumatoid Arthritis from the Perspective of a Ge 2021 Feb BACKGROUND: General practitioners, specialists, occupational and physical therapists, nursing services and other professional groups are all involved in the treatment of patients with rheumatoid arthritis. This study aims to describe interprofessional cooperation in daily ambulatory care from the perspective of a general practitioner. METHODS: The cross-sectional study investigated cooperation between general practitioners (n=121 in 68 medical practices) and several other health care providers in Hesse and Rhineland Palatinate, Germany, from February to September 2017. It was part of the prospective cohort study PANORA (Prevalence of anti-cyclic citrullinated peptide (anti-CCP) positivity in patients with new onset of non-specific musculoskeletal symptoms). The questionnaire that was used contained closed-ended questions on socio-demographics and frequency of contact, and asked physicians to assess and weigh existing collaboration. Descriptive statistics were used for data analysis. RESULTS: When caring for patients with rheumatoid arthritis, 70%, of the physicians often took responsibility for synchronizing medications, and discussing diagnoses and test results. The most frequent cooperation was with rheumatologists and was considered as highly important but the least satisfactory. The second most frequent cooperation was with physical therapists and this was also rated as very important. Physicians had highest level of satisfaction with their collaboration with the nursing services. CONCLUSION: This study shows that general practitioners perform several medical tasks when treating patients with rheumatoid arthritis. During the process, they work together with several health care providers to various degrees. Cooperation with rheumatologists and physical therapists is particularly important to general practitioners; cooperation with rheumatologists is considered inadequate and in need of improvement.
33479090 Tuberculous arthritis of the ankle joint masquerading as rheumatoid arthritis in a patient 2021 Jan Tuberculosis is an airborne multisystemic disease which primarily infects the lungs. Isolated tuberculous arthritis is rare. We present a case of a 41-year-old woman with a known case of lupus nephritis class IV who complained of pain and swelling over her left ankle joint for several months. She was treated for rheumatoid arthritis and was started with immunosuppressive agents. However, she did not improve with treatment and was later diagnosed with tuberculous arthritis based on a molecular study from joint aspiration. She was started on antituberculosis medication and showed improvement. We highlight the challenges in reaching the diagnosis and the importance of including tuberculous arthritis in differential diagnoses in cases with persistent ankle swelling.
