Adherence to and patient's knowledge of self-management of subcutaneous biologic therapy in chronic inflammatory rheumatic diseases: results of a multicentre cross-sectional study.

OBJECTIVES: Non-adherence to biologic therapy is an issue in chronic inflammatory rheumatic diseases (CIRDs) and might be related to poor patient knowledge of the risk of these therapies. Our aim here was to evaluate the level of patient adherence to and knowledge of self-care safety skills for biologic therapy. METHODS: This was a multicentre, cross-sectional study in which out-patients visited an office- or hospital-based rheumatologist. All the patients received subcutaneous biologic therapy for CIRDs. We collected data on: 1. the level of CIRD patient adherence to current subcutaneous biologic therapy using both the self-administered Compliance Questionnaire Rheumatology 5 items (CQR5) and a simple adherence question; 2. patients' knowledge of self-management of biologic therapy by the self-administered BIOSECURE questionnaire; 3. sources of information related to biologic therapy. RESULTS: In all, 285 patients (rheumatoid arthritis, n=103; spondyloarthritis, n=153; psoriatic arthritis, n=25) were enrolled by 19 rheumatologists. The mean (SD) biologic therapy duration was 5.9 (4.9) years. Adherence to the current biologic therapy was high (79.3% and 57.5% according to the CQR5 questionnaire and the adherence question, respectively). Level of knowledge of self-care safety skills (median BIOSECURE score 71) was in the acceptable range. Level of adherence and level of knowledge of self-care safety skills for biologic therapy were not associated. Patients declared that the main sources of information were their rheumatologist (92.6%) and the rheumatology team (30.5%). CONCLUSIONS: According to the patients' estimation, adherence to biologic therapy and the level of knowledge of self-care safety skills related to biologic therapy are acceptable, and these domains are not related (e.g. level of adherence and level of knowledge of risks).

Efficacy of anakinra in gouty arthritis: a retrospective study of 40 cases.

INTRODUCTION: Gout is a common arthritis that occurs particularly in patients who frequently have associated comorbidities that limit the use of conventional therapies. The main mechanism of crystal-induced inflammation is interleukin-1 production by activation of the inflammasome. We aimed to evaluate the efficacy and tolerance of anakinra in gouty patients. METHODS: We conducted a multicenter retrospective review of patients receiving anakinra for gouty arthritis. We reviewed the response to treatment, adverse events and relapses. RESULTS: We examined data for 40 gouty patients (32 men; mean age 60.0 ± 13.9 years) receiving anakinra. Mean disease duration was 8.7 ± 8.7 years. All patients showed contraindications to and/or failure of at least two conventional therapies. Most (36; 90%) demonstrated good response to anakinra. Median pain on a 100-mm visual analog scale was rapidly decreased (73.5 (70.0 to 80.0) to 25.0 (20.0 to 32.5) mm, P < 0.0001), as was median C-reactive protein (CRP) level (130.5 (55.8 to 238.8) to 16.0 (5.0 to 29.5) mg/l, P < 0.0001). After a median follow-up of 7.0 (2.0 to 13.0) months, relapse occurred in 13 patients after a median delay of 15.0 (10.0 to 70.0) days. Seven infectious events, mainly with long-term use of anakinra, were noted. CONCLUSIONS: Anakinra may be efficient in gouty arthritis, is relatively well tolerated with short-term use, and could be a relevant option in managing gouty arthritis when conventional therapies are ineffective or contraindicated. Its long-term use could be limited by infectious complications.
