OP0269 HPR PATTERNS OF FATIGUE AND PREDICTORS OF SIGNIFICANT IMPROVEMENT IN THE 1ST YEAR OF RA: RESULTS FROM THE CANADIAN EARLY ARTHRITIS COHORT (CATCH)

Background Fatigue is common in early RA(ERA) and though some patients experience improvement in fatigue when disease is well controlled, others experience persistent fatigue associated with work disability, poor QOL, and depression. Objectives To compare patterns and predictors of improved vs. persistent fatigue in the first year of ERA. Methods Data were from ERA patients (symptoms Results The 1002 pts were mostly white (81%), female (71%), with a mean (SD) age of 54 (15); 32% were obese. 70% had high fatigue at baseline; these patients were more obese, had OA/backpain, poor sleep, depression, major stress, and higher disease activity (Table 1). Among those with initial high fatigue, 30% had persistent fatigue at 12 months and was associated with obesity, comorbidities, FM, longer symptom duration, and slightly lower baseline fatigue. Predictors of improved fatigue in multivariable models were BMI Conclusion Fatigue is common in ERA and associated with active disease, worse pain and disability, obesity, depression, major stressors, poor sleep and OA/backpain. In high fatigue pts, those who are not obese, have higher pain, and take ≥20 mg MTX are more likely to improve over the first year. Optimizing weight, sleep, physical and emotional health and MTX use may improve persistent fatigue beyond control of RA inflammation. Disclosure of Interests Susan J.
