Dengue fever-induced thrombotic microangiopathy: An unusual cause of renal failure

Abstract

Dengue fever is a tropical infection, which is mosquito-borne disease, caused by dengue virus and spread by Aedes mosquitoes. The incidence of dengue fever has risen rapidly over the past few years. About half of dengue infections are asymptomatic, and a great majority present with fever and body ache. However, the occurrence of complications is well known, including acute kidney injury (AKI). AKI in dengue is usually attributable to a pre-renal cause. Thrombotic microangiopathy is an extremely rare complication of dengue fever, with only a few published case reports in medical literature. This case intends to highlight the importance of recognizing dengue fever-induced thrombotic microangiopathy by physicians and pathologists, enabling better diagnosis and management of this life-threatening condition
