The relationship between bristol rheumatoid arthritis fatigue scales and disease activity of patients with rheumatoid arthritis

Fatigue is a symptom that affects the 40-80% of patients with rheumatoid arthritis (RA) and impairs the quality of life. The aim of this study was to assess multidimensional fatigue scales, the Bristol Rheumatoid Arthritis Fatigue Multidimensional Questionnaire (BRAF-MDQ) and the Bristol Rheumatoid Arthritis Fatigue Numerical Rating Scale (BRAF-NRS) and to evaluate their relationship with disease activity in Turkish RA patients. The study included 180 patients with RA. The Disease Activity Score (DAS28), Clinical Disease Activity Index (CDAI), and Simplified Disease Activity Index (SDAI) were used to evaluate disease activity. The participants comprised of 142 females and 38 males. The mean +/- standard deviations of DAS28, CDAI, and SDAI were 3 +/- 1.24, 9.51 +/- 7.96, and 10.5 +/- 8.38 respectively. All scales except the emotional subscale were correlated with disease activity. The emotional subscale correlated with CDAI and SDAI but not with DAS28. The results of the study indicated that fatigue and disease activity were correlated. Fatigue is a symptom that impairs the quality of life but it can be easily coped with by controlling disease activity. Thus, it should be assessed in a multidimensional perspective.
