Abstract

Abstract : Background: Chikungunya fever is caused by a virus of the family Togaviridae and the genus Alphavirus, The first epidemic occurred in Africa in 1952, transmitted by mosquitoes of the genus Aedes. In Brazil, the first cases were registered in 2014. Clinical manifestations include fever, polyarthralgia, joint oedema, arthritis and morning stiffness. Diagnosis is confirmed by IgM/IgG serology for Chikungunya. The persistence of joint symptoms for a long time is an important feature of the disease. Objectives: To evaluate the prevalence of rheumatologic manifestations in 76 patients with Chikungunya infection, during an epidemic occurred in 2016 in the city of Rio de Janeiro, Brazil. Methods: To evaluate the prevalence of rheumatologic manifestations in 76 patients with Chikungunya infection, during an epidemic occurred in 2016 in the city of Rio de Janeiro, Brazil. Results: Females were the most prevalent: 65 patients (85, 5%); male sex: 11 (14, 5%). The mean age of the patients was 57, 17 years, The youngest at age 24 and the oldest 87 years old. The time between the onset of symptoms and the first consultation with a rheumatologist ranged from 11 days to the highest period of 40 weeks. Among articular symptoms, polyarthralgia occurred with higher prevalence (39 patients, 51, 31%), affecting wrists, ankles, shoulders, knees and hands. Twenty six patients had arthritis (34, 21%), Tendinopathy in 27 regions, being more common in shoulders, ankles and wrists and including De Quervain. Paresthesias occurred in 7 patients, prevailing carpal tunnel syndrome and one patient presented dactylitis. Symptoms persisted for months in all patients. Conclusions: Chikungunya is an endemic disease in Brazil, with severe joint manifestations and chronic symptoms. Often there is delay in starting treatment with rheumatologist, resulting in worsening of the clinical picture. References: [1] Lima-Camara TN.
