AB0174 FATIGUE IN RHEUMATOID ARTHRITIS: A CASE-CONTROL STUDY
Background:Fatigue is a common symptom in many chronic inflammatory diseases, including rheumatoid arthritis (RA). It is considered one of the most frustrating, uncontrollable, and overwhelming symptoms. However, most of rheumatologists do not assess fatigue despite its clinical significance and its impact on patients’ lives.Objectives:The aims of this study were to determine whether RA patients express more fatigue than healthy controls, and to analyze its correlation with disease activity.Methods:We conducted a cross-sectional study including patients with RA (ACR/EULAR 2010) and healthy controls matched for sex and age. Patients with other acute or chronic diseases that may induce fatigue (such as cancer, infection or depression) were excluded. Demographic data and the following clinical parameters were collected: pain Visual Analog Scale (VAS), Global Patient Assessment (GPA), tender joint count (TJC) and swollen joint count (SJC), Erythrocyte Sedimentation Rate (ESR), C Protein Reactive (CRP), Disease Activity Score 28 (DAS28), and Health Assessment Questionnaire (HAQ). Fatigue was assessed using the Functional Assessment of Chronic Illness Therapy – Fatigue (FACIT-F) which is a short 13-item questionnaire validated in RA. The score FACIT-F ranges between 0 and 52. Fatigue was considered mild if the FACIT-F score was ≥40, moderate if 20≤FACIT-F<40 and severe if 0≤FACIT-F<20. A p value inferior to 0.05 was considered significant.Results:We included 100 RA patients (84 women and 16 men) with a mean age of 49.5±10 years old [18-65]. The mean disease duration was 87.3 months [1-360]. The mean pain VAS was 49 cm [0-100] and the mean GPA was 47.8 cm [0-100]. The mean TJC and SJC were 5.3 [0-36] and 1 [0-9] respectively. The mean levels of ESR and CRP were 38.1 mm [10-120] and 10.8 mg/l [2-61] respectively. The mean DAS28 ESR was 3.68 [1.90-8.33] and the mean HAQ score was 0.90 [0-2.75].Thirty-nine healthy controls were enrolled including 35 women and 4 men with a mean age of 51.2 years old [30-64].The mean FACIT-F score was 27.1 [0-51] in RA patients versus 46.2 [0-52] in healthy controls (p<0.001). Among RA patients, 57% had moderate fatigue and 26% had severe fatigue.A significant negative correlation was noted between the FACIT-F score and the following parameters in RA patients: TJC (r=-0.568, p<0.001), SJC (r=-0.274, p<0.001), pain VAS (r=-0.605, p<0.001), GPA (r=-0.658, p<0.001), ESR (r=-0.405, p<0.001), CRP (r=-0.149, p<0.001), DAS28 (r=-0.837, p<0.001) and HAQ (r=-0.634, p<0.001).Conclusion:Fatigue was significantly more observed in RA patients. This symptom was correlated with disease activity and disability. It is important to recognize and manage fatigue in order to improve patients’ quality of life.Disclosure of Interests:None declared
