AbstractThis study aimed to evaluate the short-term effectiveness and safety profiles of baricitinib and explore factors associated with improved short-term effectiveness in patients with rheumatoid arthritis (RA) in clinical settings. A total of 113 consecutive RA patients who had been treated with baricitinib were registered in a Japanese multicenter registry and followed for at least 24 weeks. Mean age was 66.1 years, mean RA disease duration was 14.0 years, 71.1% had a history of use of biologics or JAK inhibitors (targeted DMARDs), and 48.3% and 40.0% were receiving concomitant methotrexate and oral prednisone, respectively. Mean DAS28-CRP significantly decreased from 3.55 at baseline to 2.32 at 24 weeks. At 24 weeks, 68.2% and 64.1% of patients achieved low disease activity (LDA) and moderate or good response, respectively. Multivariate logistic regression analysis revealed that no previous targeted DMARD use and lower DAS28-CRP score at baseline were independently associated with achievement of LDA at 24 weeks. While the effectiveness of baricitinib was similar regardless of whether patients had a history of only one or multiple targeted DMARDs use, patients with previous use of non-TNF inhibitors or JAK inhibitors showed lower rates of improvement in DAS28-CRP. The overall retention rate for baricitinib was 86.5% at 24 weeks, as estimated by Kaplan–Meier analysis. The discontinuation rate due to adverse events was 6.5% at 24 weeks. Baricitinib significantly improved RA disease activity in clinical practice. Baricitinib was significantly more effective when used as a first-line targeted DMARDs.

Abstract Background Tapering or stopping biological disease-modifying anti-rheumatic drugs has been proposed for patients with rheumatoid arthritis (RA) in remission, but it frequently results in high rates of recurrence. This study evaluates the efficacy and safety of tacrolimus (TAC) as maintenance therapy in patients with established RA in remission after receiving combination therapy with tumor necrosis factor inhibitor (TNFi) and methotrexate (MTX). Methods This 24-week, prospective, open-label trial included patients who received TNFi and MTX at stable doses for ≥24 weeks and had low disease activity (LDA), measured by Disease Activity Score-28 for ≥12 weeks. Patients selected one of two arms: maintenance (TNFi plus MTX) or switched (TAC plus MTX). The primary outcome was the difference in the proportion of patients maintaining LDA at week 24, which was assessed using a logistic regression model. Adverse events were monitored throughout the study period. Results In efficacy analysis, 80 and 34 patients were included in the maintenance and switched arms, respectively. At week 24, LDA was maintained in 99% and 91% of patients in the maintenance and switched arms, respectively (odds ratio, 0.14; 95% confidence interval, 0.01–1.59). Drug-related adverse effects tended to be more common in the switched arm than in the maintenance arm (20.9% versus 7.1%, respectively) but were well-tolerated. Conclusion This controlled study tested a novel treatment strategy of switching from TNFi to TAC in RA patients with sustained LDA, and the findings suggested that TNFi can be replaced with TAC in most patients without the patients experiencing flare-ups for at least 24 weeks.

Background:Smoking is one of the most significant modifiable exosomes risk factors for rheumatoid arthritis (RA) (1). Studies suggest that 25-30% of people with RA in Denmark smoke (2). This is almost twice as many as in the background population in Denmark. People with RA have a significant increased risk of severe comorbidity including cardiovascular disease. In addition, there are indications that smokers with RA have a poorer effect of the medical inflammatory treatment compared to non-smokers, and consequently more difficult to achieve remission of the disease activity (3). Tobacco addiction is complex and can be a challenge in smoking cessation. In addition to physiological dependence, habits and social and environmental factors may influence addiction. Tobacco smoking is associated with an addiction to nicotine and it is unexplored how this addiction appears in people with RA.Objectives:The aim of this study was to examine from the patient’s perspective how tobacco addiction appears in people with rheumatoid arthritis.Methods:We conducted a qualitative study based on a hermeneutics approach. People with RA who previously had participated in a randomized controlled study (4) about smoking cessation conducted at the Center for Rheumatology and Spine Diseases at Rigshospitalet, Denmark were recruited for semi-structured interviews.Results:In total, 12 people with RA (50% female) were included in the study. The median age was 62 years and median RA disease duration was 12 years. The degree of physical dependence measured by Fagerströms Test for Nicotine dependence (FTND) was on average: 4.9 (score: 0-10, 0=nonphysical dependence).Three categories of how tobacco addiction appeared emerged during the analysis: 1)It develops into ingrown habitsreferring to the fact that smoking already in adolescence contributes to the development of specific physical, mental and social smoking behavior. Not all individuals considered themselves addicted to nicotine as they did not necessarily connect the nicotine to the ingrown habits. 2)The body craves for nicotinereferring to nicotine proved calming, while a lacking or insufficient dose caused withdrawal symptoms. Furthermore, smoking became a habit where a craving for smoking occurred in certain situations. 3)Ambivalence – for and againstreferring to the physical dependence and smoking habits making a smoking cessation difficult. Dependency to nicotine and challenges to quit smoking led to a feeling of ambivalence and a lack of control.Conclusion:Tobacco addiction appeared as a physical dependence and a habit, which, during a smoking cessation, led to ambivalent feelings. Therefore, based on this study, there is still a need for health professionals to talk to patients about smoking. But also, a need to articulate the complexity of addiction in order to support for smoking cessations. Information should be strengthened in the clinical practice in relation to nicotine’s implication in tobacco addiction as well as the consequences of tobacco smoking for individuals with RA.References:[1]Scott DL, Wolfe F, Huizinga TW.

Background:Despite therapeutic advances in recent years, methotrexate (MTX) remains the gold standard for the treatment of rheumatoid arthritis (RA). Among the side effects that have been blamed on it are liver fibrosis (LF) and cirrhosis, although late studies have failed to show such a relation1,2. The only validated test in the diagnosis of LF is biopsy. Given the relevance of MTX in the treatment of RA, it is important to evaluate non-invasive diagnostic options for LF such as transitional elastography (FibroScan, FS).Objectives:To evaluate the percentage of LF in RA patients treated with MTX. Secondly, to assess the correlation between altered liver function, RA activity, and LF. To determine whether dose and/or duration of treatment with MTX may affect the development of LF in such patients.Methods:We did a prospective study between February 2019 and January 2020. Patients affected of RA treated with MTX were included. Patients with basal liver disease (hepatitis B, hepatitis C and steatohepatitis), alcohol consumption, type I diabetes mellitus, chronic renal failure, heart failure, obesity and concomitant treatment with leflunomide or antiretrovirals were excluded. Demographic, clinical, analytical and therapeutic variables were collected. Liver fibrosis was assessed by FS in kilopascals (kpa) and using the APRI score. RA activity was assessed by DAS28 score. Continuous variables are described with mean and standard deviation (SD), and qualitative variables are shown with absolute value and percentage. Spearman’s and Mann-Whitney’s U tests were used for the bivariate analysis.Results:Fifty patients were included (Table 1 and 2). Of these, 38 were women (76%) with mean age of 61.8 years (SD 11.7) and mean RA evolution time of 13.7 years (SD 8.2). The mean DAS28 at the visit was 2.39 (SD 1.1). The FS showed an average of 4.8 kpa (SD 2). The mean duration of treatment with MTX was 85.8 months (SD 93.3) and that of AD-MTX was 5414.6mg (SD 5011). Patients were divided into those with DA-MTX greater than 4000mg (21, 42%) and less than 4000mg (29, 58%) and no significant differences were found in terms of LF in FS (p 0.637) or APRI scale (p 0.806). No significant differences were found in terms of treatment duration either. Six patients (12%) had elevated aspartate aminotransferase (AST) and 9 (18%) had elevated alanine aminotransferase (ALT). No significant difference was found in FS values in relation to ALT, but it was with elevated AST (p 0.021). Similarly, differences were found in APRI based on AST (p 0.045). Metabolic syndrome was collected in 4 patients (8%) without significant differences with FS or APRI values. There were no significant differences in LF depending on gamma-glutamyl transpeptidase (GGT) values.Conclusion:FS and APRI score are useful for the determination of LF in RA patients treated with MTX. There is no evidence of a relationship between AD-MTX and LF by FS or APRI. AST values may be related to the presence of fibrosis as determined by FS or APRI. and the presence of the metabolic syndrome are not.References:[1]G.L. Erre, et al.
