The patient scored 4 in the Visual Triage Checklist of acute respiratory symptoms; a COVID-19 swab was taken. Prompt review of the peripheral blood smear showed evidence of microangiopathic haemolytic anaemia and thrombocytopenia. Because the patient had a picture of thrombotic thrombocytopenic purpura, plasma exchange and corticosteroids were started immediately. After 3 days, he developed severe ischaemic stroke and his swabs came back positive for COVID-19 by reverse transcription PCR. Therefore, triple therapy was started (lopinavir/ritonavir, ribavirin and interferon beta-1b). White blood cell count reached 50×109/L (normal range, 4.5–11×109/L), mainly neutrophils. All the workup for autoimmune diseases was negative. The patient showed delayed improvement in lactate dehydrogenase, haemoglobin and platelet count until we increased the volume of plasma exchange and subsided the inflammatory response of COVID-19. After that, the patient showed an excellent recovery. ER -
