Abstract

ABSTRACT: Acute kidney injury (AKI) is a neglected and least studied complication of dengue. AKI secondary to thrombotic thrombocytopenic purpura (TTP) in dengue is extremely rare and there are few case reports. A 2.5-year-old boy with dengue who developed TTP in the critical phase of illness is described. He presented with microangiopathic haemolysis, thrombocytopenia and AKI. Haemolytic uraemic syndrome (HUS)/TTP was suspected and he underwent seven cycles of plasma exchange along with renal replacement therapy, following which he made a complete recovery. Prompt recognition of renal complications in dengue fever and early initiation of appropriate renal replacement therapy along with plasma exchange are essential for a good outcome.
