Efficacy and Safety of Adalimumab in Ankylosing Spondylitis: Data From Real Life

Abstract

Rationale. Data from controlled trials showed that adalimumab, a humanized anti-TNF monoclonal antibody, is effective and safe in the treatment of ankylosing spondylitis (AS). Objectives. The present study aimed to observe the effi cacy and safety of adalimumab in AS in a real life clinical setting. Methods. The study observed cross-sectionaly and retrospectively the efficacy and safety of adalimumab in all the patients admitted to the Rheumatology Department of “Sfânta Maria” Clinical Hospital between January 2008 and June 2013 who were classified as having AS according to the modified New York criteria. The diagnosis and follow-up of uveitic cases were done in the Ophthalmology Department of the Emergency University Hospital. Results. Within the study time-frame, 79 AS patients met the inclusion criteria: 71 (89.9%) had adalimumab for at least 24 months; 8 (10.1%) switched from adalimumab to another biological, as follows: 3 (3.8%) because of serious adverse events, 3 (3.8%) were primary non-responders and 2 (2.5%) were secondary non-responders. The clinical response was fast: after 3 months of treatment, 59 (83.1%) patients had BASDAI < 4 and 55 (77.5%) patients had BASFI < 4. Regarding safety, the serious adverse effects recorded were: infectious arthritis, pulmonary tuberculosis, pulmonary sarcoidosis. There were no cases of cancer or demyelinating disease during the study frame. Conclusions. Therapy with adalimumab in AS produces a prompt and lasting effect. The efficacy (remission) and safety (adverse events) of adalimumab can be monitored in the real-life clinical setting using BASDAI, BASFI, and routine clinical evaluations. Clinicians may need to expect a slightly higher rate of serious adverse events and rate of treatment discontinuation than those reported by controlled trials.
