Prevalencia de fibromialgia en pacientes con artritis reumatoide y su asociación con mayor actividad de la enfermedad en el Hospital José Carrasco Arteaga y el Hospital Santa Inés. Cuenca. 2021

Abstract

Background: Fibromyalgia (FM) is a central sensitization syndrome that occurs in specific anatomical areas tender to palpation, accompanied by fatigue, sleep and cognitive disturbances. It has been seen that this pathology accompanies other rheumatic diseases, including rheumatoid arthritis (RA), in which cases a greater disease activity has been found. Objective: To determine the prevalence of fibromyalgia in patients with rheumatoid arthritis and its relationship with the disease activity in the outpatient service of rheumatology on the Jose Carrasco Arteaga Hospital and Hospital Santa Inés. Methods: Cross-sectional analytical and prevalence study. The universe consisted in 190 patients diagnosed with RA. The data was obtained using forms. The statistical measures used were frequencies and percentages. In order to find out the difference between groups and to verify the hypothesis, Chi square was used. The Prevalence Ratio (PR) and its 95% confidence interval (95% CI) were determined. Results: Of the 190 patients, 69.87% (n=129) were between 35-64 years, 90.53% (n = 172) were women, a prevalence of 13.68% (n = 26) of secondary FM was obtained, 92.3% (n = 24) of this last group presented a moderate to high disease activity, finding a risk association for greater disease activity (p<0.00 PR = 19.74 CI = 95%). Conclusions: The prevalence of secondary FM in RA patients was considerable in the studied group; a risk association was found between the presence of secondary FM in RA and a higher disease activity. Non statistical relationship was found between the time of RA diagnosis and the disease activity.
