RESUMO
BACKGROUND: The vast majority of patients with rheumatoid arthritis (RA) included in the national database of the German Collaborative Arthritis Centers are treated with disease-modifying antirheumatic drugs (DMARD). The clinical and patient-related characteristics of patients who did not have DMARD treatment in the longer term were investigated. METHODOLOGY: Between 2012 and 2016 a total of 10,289 patients with RA were documented. Patient characteristics, disease activity and severity, comorbidities and concomitant treatment were descriptively evaluated. Patients who were without DMARDs for more than 1 year and not in remission (disease activity score 28, simple disease activity index or Boolean remission) were analyzed separately. Logistic regression was used to investigate which variables were associated with DMARD treatment. RESULTS: A total of 426 patients were ≤1 year without DMARDs, 1090â¯> 1 year without DMARDs and 8773 (85%) currently had DMARD treatment. Of the patients who were without DMARDs for more than 1 year, 51% were in remission. Even if no remission criteria were met, the rheumatologists nevertheless found the strived for RA situation in the majority of patients. Of the patients who were without DMARDs for more than 1 year, 13% received glucocorticoid treatment >5â¯mg/day. In patients with a high degree of severity (odds ratio, OR severe vs. asymptomatic/mild 2.33, 95% confidence interval, CI 1.80;3.02) or positive rheumatoid factor (OR 2.24, CI 1.96;2.56) the chance of receiving DMARD treatment was twice as high. Existing comorbidities did not reduce the chance of receiving DMARD treatment. CONCLUSION: The RA patients in the national database who had no DMARDs for more than 1 year were mostly in remission or with low disease activity. Signs of inadequate disease control were found in only 11% of all patients without DMARD treatment.
