Caracterização clínica e epidemiológica da fase subaguda ou crônica na infecção pelo vírus CHIKUNGUNYA numa capital do nordeste brasileiro

Abstract

Chikungunya fever is an arbovirosis emerging in Brazil since 2014 characterized by an acute viral condition, with intense arthralgia that may progress to a subacute or chronic form. In 2015, the State of Sergipe, in Brazilian Northeast, presented the second highest incidence rate per 100 thousand inhabitants in the country. This is a descriptive trial of case series aimed at epidemiological and clinical evaluation in the subacute or chronic phase of Chikungunya virus infection in a sample of 114 patients who presented the acute form of this disease from January 2015 to March 2017. There was a predominance of women (83%) aged between 50 and 59 years old (27%) and from Aracaju, Sergipe, Brazil (66%). The level of schooling was the high school for 31% of them and their family income was less than or equal to 1 minimum wage for 77%, with a predominance of housewives (24.5%). We noted polyarticular involvement (75%), with a highlight for ankle tenosynovitis (42%) and upper-limb paresthesia (77%). The most prevalent comorbidity was systemic arterial hypertension (38%). The mean duration of joint symptoms was 6.8 months; pain intensity on a visual analog scale (VAS) from 0 to 10, 7.2; for painful joints, 10.15; and for swollen joints, 2.93. The findings make it possible to draw the epidemiological and articular profile, as well as other clinical conditions, in patients affected by this alarming infection, presenting data compatible with what has already been described in the literature.
