ABSTRACT: Purpose of review
Patients on disease-modifying anti-rheumatic drugs (DMARDs) remain concerned about potential risks of severe COVID-19 outcomes. Meanwhile, several DMARDs have been proposed as COVID-19 therapies.Recent findings
In patients with autoimmune diseases, baseline glucocorticoid use is associated with severe COVID-19. While classes of DMARDs (e.g., conventional synthetic, targeted synthetic, and biologic) do not appear to be associated with higher risk, specific medications such as rituximab and sulfasalazine may be associated. Randomized clinical trials (RCTs) show that glucocorticoids reduce mortality in severe COVID-19. RCTs suggest other agents, such as baricitinib, may improve COVID-19 outcomes in certain populations. Baseline glucocorticoid use raises the risk of severe COVID-19 in patients with autoimmune diseases, but glucocorticoids are an effective treatment for those with severe COVID-19. Further research is needed to inform DMARD management in autoimmune disease patients during the pandemic and the role of DMARDs in COVID-19 treatment.

Project description:ObjectivesTo investigate the incidence of COVID-19 in a cohort of adult and paediatric patients with rheumatic diseases receiving targeted biologic and synthetic disease modifying anti-rheumatic drugs (tDMARDs) and to explore the possible effect of these treatments in the clinical expression of COVID-19.MethodsA cross-sectional study comprising of a telephone survey and electronic health records review was performed including all adult and paediatric patients with rheumatic diseases treated with tDMARDs in a large rheumatology tertiary centre in Barcelona, Spain. Demographics, disease activity, COVID-19 related symptoms and contact history data were obtained from the start of the 2020 pandemic. Cumulative incidence of confirmed cases (SARS-CoV-2 positive PCR test) was compared to the population estimates for the same city districts from a governmental COVID-19 health database. Suspected cases were defined following WHO criteria and compared to those without compatible symptoms.Results959 patients with rheumatic diseases treated with tDMARDs were included. We identified 11 confirmed SARS-CoV-2 positive cases in the adult cohort and no confirmed positive cases in the paediatric cohort. COVID-19 incidence rates of the rheumatic patient cohort were very similar to that of the general population [(0.48% (95% CI 0.09 to 0.87%)] and [0.58% (95% CI 0.56 to 0.60%)], respectively. We found significant differences in tDMARDs proportions between the suspected and non-suspected cases (p=0.002).ConclusionAdult and paediatric patients with rheumatic diseases on tDMARDs do not seem to present a higher risk of COVID-19 or a more severe disease outcome when compared to general population.

Project description:ObjectivesThe effectiveness of inactivated influenza vaccine in people with autoimmune rheumatic disease (AIRDs) is not known. We investigated whether the influenza vaccine is effective in preventing respiratory morbidity, mortality and all-cause mortality in AIRD patients.MethodsAdults with AIRDs treated with DMARDs prior to 1 September of each year between 2006 and 2009, and 2010 and 2015 were identified from the Clinical Practice Research Datalink. Exposure and outcome data were extracted. Data from multiple seasons were pooled. Propensity score (PS) for vaccination was calculated. Cox-proportional hazard ratios (HRs) and 95% CIs were calculated, and were (i) adjusted, (ii) matched for PS for vaccination.ResultsData for 30 788 AIRD patients (65.7% female, 75.5% with RA, 61.1% prescribed MTX) contributing 125 034 influenza cycles were included. Vaccination reduced risk of influenza-like illness [adjusted HR (aHR) 0.70], hospitalization for pneumonia (aHR 0.61) and chronic obstructive pulmonary disease exacerbations (aHR 0.67), and death due to pneumonia (aHR 0.56) on PS-adjusted analysis in the influenza active periods (IAPs). The associations were of similar magnitude and remained statistically significant on PS-matched analysis except for protection from influenza-like illness, which became non-significant. Sub-analysis restricted to pre-IAP, IAP and post-IAP did not yield evidence of residual confounding on influenza-like illness and death due to pneumonia. Vaccination reduced risk of all-cause mortality, although IAP-restricted analysis demonstrated residual confounding for this outcome.ConclusionInfluenza vaccine associates with reduced risk of respiratory morbidity and mortality in people with AIRDs. These findings call for active promotion of seasonal influenza vaccination in immunosuppressed people with AIRDs by healthcare professionals.

Project description:Inflammation is strongly implicated in the pathogenesis of abdominal aortic aneurysms (AAA). This review examined the potential role of biologic disease-modifying anti-rheumatic drugs (bDMARDs) as repurposed drugs for treating AAA. Published evidence from clinical and preclinical studies was examined. Findings from animal models suggested that a deficiency or inhibition of tumour necrosis factor-α (TNF-α) (standard mean difference (SMD): -8.37, 95% confidence interval (CI): -9.92, -6.82), interleukin (IL)-6 (SMD: -1.44, 95% CI: -2.85, -0.04) and IL-17 (SMD: -3.36, 95% CI: -4.21, -2.50) led to a significantly smaller AAA diameter compared to controls. Human AAA tissue samples had significantly increased TNF-α (SMD: 1.68, 95% CI: 0.87, 2.49), IL-1β (SMD: 1.93, 95% CI: 1.08, 2.79), IL-6 (SMD: 2.56, 95% CI: 1.79, 3.33) and IL-17 (SMD: 6.28, 95% CI: 3.57, 8.99) levels compared to non-AAA controls. In human serum, TNF-α (SMD: 1.11, 95% CI: 0.25, 1.97) and IL-6 (SMD: 1.42, 95% CI: 0.91, 1.92) levels were significantly elevated compared to non-AAA controls. These findings implicate TNF-α, IL-17 and IL-6 in AAA pathogenesis. Randomised controlled trials testing the value of bDMARDs in limiting AAA growth may be warranted.

Project description:The outbreak of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has posed the world at a pandemic risk. Coronavirus-19 disease (COVID-19) is an infectious disease caused by SARS-CoV-2, which causes pneumonia, requires intensive care unit hospitalization in about 10% of cases and can lead to a fatal outcome. Several efforts are currently made to find a treatment for COVID-19 patients. So far, several anti-viral and immunosuppressive or immunomodulating drugs have demonstrated some efficacy on COVID-19 both in vitro and in animal models as well as in cases series. In COVID-19 patients a pro-inflammatory status with high levels of interleukin (IL)-1B, IL-1 receptor (R)A and tumor necrosis factor (TNF)-? has been demonstrated. Moreover, high levels of IL-6 and TNF-? have been observed in patients requiring intensive-care-unit hospitalization. This provided rationale for the use of anti-rheumatic drugs as potential treatments for this severe viral infection. Other agents, such as hydroxychloroquine and chloroquine might have a direct anti-viral effect. The anti-viral aspect of immunosuppressants towards a variety of viruses has been known since long time and it is herein discussed in the view of searching for a potential treatment for SARS-CoV-2 infection.

Project description:ABSTRACT Background We investigated the incidence of chronic kidney disease (CKD) progression and its factors relevant to patients with stable rheumatoid arthritis (RA). Methods We enrolled consecutive patients with RA who had initiated treatment with a biologic disease-modifying anti-rheumatic drug (bDMARD) at our institution and continued the same drug for >5 years between 2001 and 2016. Patients with CKD at bDMARD initiation were excluded. C-reactive protein (CRP) level, Clinical Disease Activity Index (CDAI) score and estimated glomerular filtration rate were measured every 6 months. Results We included 423 patients, with 196 on tumour necrosis factor inhibitors, 190 on tocilizumab and 37 on abatacept. Among these patients, 34 (8.0%) progressed to CKD within 5 years. The mean CRP level and CDAI score over 5 years were significantly lower in patients without CKD progression than in those with CKD progression (P < .001 and P = .008, respectively). Multivariable analysis revealed that age at bDMARD initiation [odds ratio (OR) 1.05, P = .002], non-steroidal anti-inflammatory drug use (OR 3.47, P = .004) and mean CRP >0.14 mg/dL (OR 5.89, P = .015) were independently associated with CKD progression, while tocilizumab use was associated with a decreased risk of CKD progression (OR 0.31, P = .027). Conclusions Controlling inflammation contributes to the inhibition of CKD progression in RA patients.

Project description:Current recommendations advocate treatment with disease-modifying anti-rheumatic drugs (DMARDs) in all patients with active rheumatoid arthritis (RA). We analyzed short-term disease outcome in patients according to the consistency of DMARD use in a clinical rheumatology cohort.Patients in an RA registry (n = 617) were studied for DMARD use at semi-annual study time points during the first 18 months of follow-up and were divided into 4 groups according to the number of study time points with any DMARD use [0-1 study time points (n = 31), 2 study time points (n = 24), 3 study time points (n = 77), and 4 study time points (n = 485)]. The primary outcome analyses were performed at 24 months and included Disease Activity Score 28 (DAS28-CRP), modified Health Assessment Questionnaire (MHAQ) change, Short Form Health Survey-12 physical and mental summary scores (SF-12 PCS, SF-12 MCS), EuroQol 5-Dimensional health index (EQ-5D), and radiographic progression. Unadjusted, adjusted, and analyses stratified for seropositivity and disease activity were performed. A secondary analysis investigated 36-month outcomes.No significant 24-month outcome differences could be found between the DMARD use categories. For seropositive patients, there was evidence of a linear trend for SF-12 PCS (p = 0.02) and EQ-5D (p = 0.01) with worse outcomes for inconsistent DMARD users. At 36 months, there was a linear trend for higher DAS28-CRP scores for inconsistent users (p < 0.01).Overall, we found poor correlation between inconsistent DMARD use and short-term disease outcome. However, outcome in the longer term could be negatively influenced by inconsistent DMARD use, as well as short-term outcome in seropositive patients.

Project description:OBJECTIVES:To address whether the use of methotrexate (MTX) and biological disease-modifying anti-rheumatic drugs (bDMARDs) impacts bone structure and biomechanical properties in patients with psoriatic arthritis (PsA). METHODS:This is a cross-sectional study in PsA patients receiving no DMARDs, MTX, or bDMARDs. Volumetric bone mineral densities (vBMDs), microstructural parameters, and biomechanical properties (stiffness/failure load) were determined by high-resolution peripheral quantitative CT and micro-finite element analysis in the respective groups. Bone parameters were compared between PsA patients with no DMARDs and those receiving any DMARDs, MTX, or bDMARDs, respectively. RESULTS:One hundred sixty-five PsA patients were analyzed, 79 received no DMARDs, 86 received DMARDs, of them 52 bDMARDs (TNF, IL-17- or IL-12/23 inhibitors) and 34 MTX. Groups were balanced for age, sex, comorbidities, functional index, and bone-active therapy, while disease duration was longest in the bDMARD group (7.8?±?7.4?years), followed by the MTX group (4.6?±?7.4) and the no-DMARD group (2.9?±?5.2). No difference in bone parameters was found between the no-DMARD group and the MTX group. In contrast, the bDMARD group revealed significantly higher total (p =?0.001) and trabecular vBMD (p =?0.005) as well as failure load (p =?0.012) and stiffness (p =?0.012). In regression models, age and bDMARDs influenced total vBMD, while age, sex, and bDMARDs influenced failure load and stiffness. CONCLUSION:Despite longer disease duration, bDMARD-treated PsA patients benefit from higher bone mass and better bone strength than PsA patients receiving MTX or no DMARDs. These data support the concept of better control of PsA-related bone disease by bDMARDs.

Project description:The constant use of disease modifying anti rheumatic drugs affects the functioning of multiple organs inside the body. Some drugs are more toxic than others. The present case control investigation was designed to evaluate the comparative toxicity of methotrexate and leflunomide on multiple organs in rheumatoid arthritis patients. For this purpose, 100 subjects with confirmed rheumatoid arthritis condition were recruited form tertiary care center. Whereas 50 age matched controls were recruited from the local healthy population. Participants of the study were categorized into three groups with equal numbers of subjects in each group (n = 50). Group 1 comprised rheumatoid arthritis patients on methotrexate treatment, group 2 included rheumatoid arthritis patients on leflunomide treatment and group 3 were healthy subjects. Cardiac and respiratory response was evaluated by monitoring blood pressure, pulse and breathing rate and spot oxygen saturation. Stress on liver was estimated by measuring change in liver enzymes (alanine transaminase, aspartate aminotransferase, and alkaline phosphatase) and total bilirubin. While, degree of renal impairment was assessed by calculating glomerular filtration rate, serum creatinine, urinary urea and uric acid. For statistical interpretation, data was subjected to independent student "t" test and analysis of variance (one way ANOVA) for mean variations. Both methotrexate and leflunomide elevated the systolic and diastolic blood pressure and pulse rate. Leflunomide maintained the oxygen saturation at 96.7%, whereas methotrexate exerted serious effect on spot oxygen saturation by reducing it significantly to 93.25% than healthy subjects. Hepatotoxicity manifested by sustained use of leflunomide was perceptible in this study group. Whereas, both methotrexate and leflunomide influenced renal function as indicated by marked increase in blood urea nitrogen (P = 0.001), serum creatinine (P = 0.007) and reduced glomerular filtration rate (P<0.0001). However, use of methotrexate demonstrated significant (P<0.0001) reduction in serum uric acid and urinary urea levels. Methotrexate is more injurious to heart, blood vessels and kidneys than leflunomide but it is less noxious to hepatic parenchyma. Contrarily, leflunomide usage is comparatively better option for respiratory, cardiovascular, and renal health but dangerous to liver. Thus, a single drug can't be prescribed for the treatment of rheumatoid arthritis for longer management of arthritis patients.

Project description:Fatigue is a common and debilitating symptom in patients with RA. Since 2007, fatigue has been included as one of the core outcome measures in RA. Clinical trials of biologic DMARDs (bDMARDs) and targeted synthetic DMARDs (tsDMARDs) have included fatigue as a secondary endpoint. A Cochrane review in 2016 concluded that the bDMARDs have a moderate effect on improving fatigue in RA. More recent clinical trials of the new biologic agent sarilumab and the Janus kinase inhibitors tofacitinib and baricitinib showed similar benefits. It remains unclear whether the effect of bDMARDs and tsDMARDs on fatigue is mediated by direct effects or through a reduction in inflammation. As fatigue was a secondary endpoint, many analyses did not adjust for potential confounding factors, including pain, mood and anaemia, which is a significant limitation.

Project description:The aim of this study was to investigate the association between body-mass index (BMI) and remission in RA patients receiving conventional synthetic (cs-) or the biological Disease-Modifying Antirheumatic Drug (DMARD), tocilizumab. Individual participant data (IPD) were pooled from five trials investigating tocilizumab and/or csDMARDs therapy (primarily methotrexate) for RA. Time to first remission was recorded according to the Simplified Disease Activity Index (SDAI) and Clinical Disease Activity Index (CDAI). BMI was classified according to WHO definitions. Associations between baseline BMI and remission were assessed by Cox-proportional hazard analysis. IPD were available from 5428 patients treated with tocilizumab ± csDMARDs (n = 4098) or csDMARDs alone (n = 1330). Of these, 1839 (33.9%) had normal BMI, 1780 (32.8%) overweight, 1652 (30.4%) obese and 157 (2.9%) were underweight. Obesity, compared to normal BMI, was associated with less frequent remission using SDAI (adjusted HR 0.80 [95% CI 0.70-0.92]) and CDAI (adjusted HR 0.77 [0.68-0.87]). As continuous variable, increased BMI was associated with less frequent SDAI (P = 0.001) and CDAI (P = 0.001) defined remission. No heterogeneity in identified associations was observed between studies (P = 0.08) or treatments (P = 0.22). Obesity was negatively associated with RA disease remission regardless of RA therapy, suggesting that baseline BMI should be considered as a stratification factor in future RA trials.
