High levels of cardiovascular biomarkers in fatal Chikungunya virus infection.

Abstract

Chikungunya virus (CHIKV) infection is an emerging arboviral disease that has spread geographically to many previously unaffected areas. Although severe cases of acute CHIKV infection have been documented, little is known about its pathogenesis. We aimed to determine the levels of cardiovascular biomarkers in fatal and non-fatal patients with acute CHIKV infection. This study included fatal and non-fatal patients with CHIKV reported to National System for Public Health Surveillance and laboratory-confirmed by the Colombian National Institute of Health. Each fatal patient was matched to 2 non-fatal patients for age (± 10 years). Blood samples were processed for cardiovascular biomarkers by multiplex immunoassays. Twenty-five cases of fatal CHIKV infection and 50 patients of non-fatal CHIKV infection were included. Nearly 20% of the population were under 10 years old and 52% were over 60. The median serum levels of endocan-1 (p = 0.000), creatine kinase MB isoenzyme (p = 0.000), oncostatin (p = 0.000), fatty-acid-binding protein 3 (p = 0.000) and fatty-acid-binding protein 4 (p = 0.000) were significantly higher in fatal CHIKV infection cases than in non-fatal patients. Troponin I tended to be higher in fatal CHIKV infection cases than in non-fatal CHIKV infection patients (p = 0.063). Among fatal patients, no significant differences were found in serum levels of cardiovascular biomarkers among younger (< 50 years-old) and older (≥ 50 years-old) patients. We found high serum levels of cardiovascular biomarkers in fatal CHIKV infection. These results promote the fact that endothelial and cardiac damage can occurs and may be significant factors related organ failure and death in these patients.
