Background An epidemic of Chikungunya Fever (CF) spread throughout South America in 2014. The acute manifestation of CF typically consists of febrile arthritis. The burden of the chronic articular manifestations remains a public health issue affecting activities of daily life. There is a very important impact on quality of life in patients affected by CF, even at chronic phase. The long-term functional status may also be affected by CF.
Objectives To evaluate longitudinally the disability, Health Related Quality of Life (HRQOL) and functional status of patients with CF and analyze the clinical and epidemiological factors associated with different outcomes.
Methods Patients with clinical and demographic diagnosis of CF and persistent articular symptoms were evaluated in a cohort study between May 2016 and December 2016. HRQOL was rated by Short-Form 12 (SF-12) and the functional status was checked through Health Assessment Questionnaire (HAQ) and the Global Functional Status (GFS). Data were divided per weeks after disease onset and were analysed (Spearmans's correlation coefficient and Mann-Whitney test).
Results Sixty-five patients (58 females), mean age of 51.3 (±13.3) were assessed. As expected, a significant correlation between pain related scores and Physical Health Composite Scale Score (PCS), HAQ and GFS was found (p<0.05)). Edema and morning stiffness correlated with PCS, HAQ and GFS status from 4 to 20 weeks after disease onset (p<0.05). There was improvement in scores of all instruments used from 4–8 weeks of disease to 12–16 weeks of disease (table 1). The worst indices of PCS, Mental Health Composite Scale Score (MCS) and GFS were scored in the first month, mean scores of 30.07±5.77, 38.13±8.54 and 3.15±1.07 respectively. Higher HAQ values were demonstrated between 4 and 8 weeks after disease onset (mean score 1.87±0.82).
Conclusions We demonstrated the impact of CF on HRQOL and Functional Status of patients. The SF-12 Health Survey, HAQ and GFS are influenced mostly by patients pain and worsening of this status are more prominent in the first 8 weeks of disease. Further clinical studies of the impact of CF on quality of life and functional studies are needed
