Resumen
GALLINO YANZI, J. et al. Evaluation of fatigue in patients with psoriatic arthritis and association with other variables of the disease. Rev. argent. reumatolg. [online]. 2016, vol.27, n.3, pp.16-20. ISSN 0327-4411.
Objective: To evaluate the frequency of fatigue in patients with PsA and its association with other disease variables. Methods: We included patients ≥18 years of age with PsA according to CASPAR criteria. Fatigue, morning stiffness, pain and global activity by both patients and physicians were assessed using visual analogue scales (VAS). ASQoL, PsAQoL, HAQ-A, BASFI and BASDAI were completed. DAS28, DAPSA and CPDAI were calculated. Results: We included 112 patients. Median fatigue VAS was 3 cm (IQR 0-6). Fatigue had an acceptable correlation with BASDAI (r:0.63), BASDAI question Nº1 (r:0.48), DAS28 (r:0.45), DAPSA (Rho:0.5), HAQ-A (Rho:0.42), PsAQoL (Rho:0.49), ASQoL (Rho:0.48), BASFI (Rho:0.47), pain (Rho:0.48) and morning stiffness (Rho:0.55) and a regular correlation with CPDAI (Rho:034). 30% of our cohort had fatigue, as defined by a VAS equal or greater than 6 cm. In multiple linear regression analysis, adjusting for sex, age and disease duration, peripheral disease activity (DAPSA βcoeff: 0.36, p=0.0001) and quality of life (PsAQoL βcoeff: 0.27, p=0.009) were associated with fatigue. Conclusion: Prevalence of fatigue in this cohort was 30% and it was associated with greater peripheral disease activity and worse quality of life.
