The aim of the study was to evaluate factors that influence health status and work disability in patients with ankylosing spondylitis (AS) in the Czech Republic. Data were collected in a retrospective fashion directly from patients with AS using mailed questionnaires containing questions regarding sociodemographic characteristics of patients, the course of their disease, therapy, rehabilitation, quality of life, and ability to work. HAQ-DI (Health Assessment Questionnaire-Disability Index) and BASDAI (Bath Ankylosing Spondylitis Disease Activity Index) were also included in the questionnaires; 1,008 questionnaires were suitable for further statistical analysis. The average age ± SD of patients was 50.2 ± 10.7 years, the average symptom duration was 23.0 ± 11.6 years. Mean time from first symptoms to diagnosis was 9.1 years. Full disability had been awarded to 303 patients (30%) at some point of their disease. Twenty seven percent of patients reported receiving full disability pension for 10 or more years. Four hundred fifty six subjects (45%) were currently or had been previously receiving partial disability pension. Receiving disability pension was more frequent among men (64%) compared to women (56%) ( P = 0.012), despite the fact that women had higher BASDAI ( P < 0.001) and HAQ-DI ( P = 0.004) scores. Patients with a family history of AS had higher BASDAI and HAQ-DI scores ( P = 0.001 and P = 0.008, respectively) compared to patients without a family history of AS. BASDAI and HAQ-DI scores correlated with age and duration of illness, younger patients and those with shorter disease duration had lower values. Fifty eight percent of patients reported a BASDAI score ≥4 (current cutoff value for initiation of biological therapy), but only 1% of patients were treated by anti TNF alpha agents within the last year. Seven hundred ninety one patients underwent spa treatment in the previous year; 96% of them experienced improvement of their health condition. [ABSTRACT FROM AUTHOR]

The study aimed to compare treatment retention for first-line TNF inhibitor (TNFi) in the ATTRA registry patients receiving either combination with conventional synthetic DMARDs or TNFi as monotherapy. A retrospective multicenter study analyzed data of all adult patients with rheumatoid arthritis (n = 3032) starting TNF inhibitor as the first-line biological therapy in combination with csDMARDs or in monotherapy from January 1st 2012 to December 31st 2020. Kaplan-Meier method was employed to calculate drug retentions. Survival curves of treatment retentions were compared through Log-rank test between the studied subgroups. The hazard ratio for drug discontinuation was assessed through univariate cox regression models. In patients who started the first line TNFi therapy, the median treatment retention was 47.7 (42.2; 53.1) months for combination therapy and 22.7 (14.9; 30.6) months for TNFi monotherapy (p < 0.001). Estimated one-year survival was higher in patients on TNFi combined with csDMARDs as compared with TNFi monotherapy (75.3% vs 65.7%); two-year survival rate was 63.2% vs 49.2%, three-year survival rate was 55.4% vs 42.4% and five-year survival 44.9% vs 26.4% of patients. The estimated survival on the first TNFi was higher in patients taking combination therapy with methotrexate than with other csDMARDs (p = 0.003). Use of csDMARDs co-medication was associated with significantly better first TNFi drug survival compared to monotherapy. The combination of TNFi with MTX is more effective than the combination with leflunomide, which did not demonstrate a significant effect., (© 2022. The Author(s).)

Objective: To compare the effectiveness, safety and costs of standard versus individually tailored reduced doses of anti-tumour necrosis factor (TNF) drugs in patients with ankylosing spondylitis (AS) after achieving low-disease activity., Methods: This was a single-centre prospective observational study performed within the ATTRA registry. The anti-TNF dose tapering strategy was chosen by treating physicians, without prespecified protocol. We used propensity score (PS) methodology to identify two cohorts of patients matched for relevant baseline characteristics who were treated with either reduced (n=53) or standard (n=83) doses of TNF inhibitors. One-year outcomes and costs of anti-TNF drugs were compared between both PS-matched cohorts., Results: In the reduced dosing group, the median dose of TNF inhibitor corresponded to 0.67 and 0.5 of the standard dose initially and at 12 months respectively, and 21% of patients required return to standard dosing regimen. The mean change per year in Bath Ankylosing Spondylitis Activity Index, C-reactive protein , Health Assessment Questionnaire Disability Index and Bath AS functional index, as well as quality-adjusted life-year area under the curve were no different between both groups. The HR (95% CI) of reduced versus standard dosing group for relapse and any adverse event was 1.46 (0.66 to 3.19) and 0.56 (0.22 to 1.44), respectively. Mean difference (95% CI) in cost of anti-TNF drugs was €-4214 (-4707 to -3701) per year of treatment in favour of reduced dosing strategy., Conclusions: In patients with AS after reaching low-disease activity, a tailored approach to reduce doses of anti-TNF drugs produced similar clinical outcomes at 1 year, but was substantially less costly., (Published by the BMJ Publishing Group Limited.

Objectives: Immune-mediated necrotizing myopathy (IMNM) is characterized by the predominant presence of necrotic muscle fibres in muscle biopsy and variable response to immunosuppressive treatment. The aims of this study were to analyse the temporal trend of IMNM incidence in our centre over the past 10 years and to explore the role of statins as possible causative agents., Methods: A retrospective evaluation of muscle biopsy results, clinical and laboratory data, including antibody associations of all patients with idiopathic inflammatory myopathy newly diagnosed between 2004 and June 2014, was performed. Available sera were tested for the presence of anti-3-hydroxy-3-methylglutaryl coenzyme A reductase (anti-HMGCR) autoantibodies., Results: Of 357 biopsied patients, 233 fulfilled criteria for inflammatory/immune-mediated myopathy, including 27 (11.6%) classified as IMNM. There were no patients with IMNM diagnosed between 2004 and 2007; subsequently, two to three cases of IMNM per year were seen during the period 2008-11, with a substantial increase to 18 cases (66.6% of all IMNM biopsies) in 2012-14. Thirteen of 27 patients (48%) had a history of statin use, 11 (85%) of whom had positive anti-HMGCR antibodies. There was no IMNM patient without a history of statin use who was anti-HMGCR antibody positive., Conclusion: Our data show an increasing incidence of IMNM, which is mainly accounted for by anti-HMGCR-positive IMNM associated with the use of statins., (© The Author 2015.

Objectives: To estimate efficacy, safety and adherence to therapy of ankylosing spondlitis (AS) patients included in the Czech National Registry ATTRA, and to look for predictive factors for therapy discontinuation., Methods: Patients were included according to the guidelines of the Czech Society for Rheumatology, which involve failure of previous therapy, BASDAI >4, and CRP >10 mg/l. Only patients with anti-TNF administered for the first time were analysed. Adherence to therapy was evaluated using Kaplan-Meier analysis and results were presented as cumulative survival. Comparison with data on patients with rheumatoid arthritis (RA) followed in the same registry was made., Results: 310 of AS patients who had reached at least 1 year as well as those who discontinued the treatment before this time point were analysed. Drug survival was longer in patients with AS than in those with RA: 84% vs. 78% and 72% vs. 49% after 1 and 3 years of treatment. Significant risk factors for treatment discontinuation were female gender (RR 2.22, p=0.001) and CRP (RR 1.33, p=0.025). The proportion of patients with BASDAI <4 during the treatment period was higher in the etanercept group than in the infliximab group (p<0.001). The number of patients fully employed increased in the whole group from 48% to 63% after 1 year of treatment., Conclusion: Follow-up of patients with AS in the national registry shows that it is an effective and safe way of treatment with longer adherence to anti-TNF therapy in comparison with RA patients.
