- Rheumatoid arthritis (RA) is a risk factor for tuberculosis (TB), particularly following treatment with biologicals. Since these therapies are increasingly used in ankylosing spondylitis (AS), other types of spondyloarthritis (SpA) and psoriatic arthritis (PsA), we investigated the corresponding TB risks in these patients.We identified individuals with AS/SpA/PsA, and non-AS/SpA/PsA comparators by linking Swedish national Patient, Population, TB and Rheumatology registers, and followed them for TB occurrence. Incidence rates were estimated for biological-naïve and biological-exposed patients, and the comparators. We calculated hazard ratios (HR) adjusted for age, sex and country of birth.38,702 patients with AS/SpA/PsA, and 200,417 general population persons were included. Among patients, 11 active TB cases were identified, with an incidence rate (per 105 ) of 22 (95%CI 8.3 to 59.2) for biological-exposed patients, 2.7 (95%CI 1.3 to 5.6) for biological-naïve patients and 2.4 (95%CI 1.8 to 3.3) for non-AS/SpA/PsA comparators. The adjusted HR comparing biological-naïve patients to the general population was 1.2 (95%CI 0.5 to 2.7), and 7.5 (95%CI 1.9 to 29) comparing biological-exposed to biological-naïve patients.Biological-naïve AS/PsA /SpA are not at an increased TB risk in Sweden. Following treatment with biologicals, risks increased but the absolute TB risk was low. This article is protected by copyright. All rights reserved.
