Thrombotic microangiopathies (TMAs) are a group of disorders characterized by microangiopathic hemolytic anemia and thrombocytopenia, leading to ischemic tissue injury. We, hereby, describe an interesting case of TMA secondary to dengue along with dengue encephalitis. Dengue-related TMA is rarely described. Treatment was initiated with standard-volume (1.5 plasma volume) therapeutic plasma exchange (TPE) by centrifugation method on a multifunctional cell separator (Spectra Optia, Terumo BCT, USA) within a few hours of admission based on high PLASMIC score, which led to improvement in hemolytic parameters and kidney injury. This case highlights the role of early diagnosis and early initiation of TPE is key in the management of dengue-related TMAs.
