Abstract

Post snake bite renal failure due to thrombotic microangiopathy (TMA) is often overlooked and not considered as a separate entity while managing the patient. This case report highlights the efficacy of Therapeutic Plasma Exchange in managing the post envenomation TMA. Anti-snake venom was administered following severe hematotoxic envenomation, but later on developed acute kidney injury and hence hemodialysis was done for 2 days without much improvement. On third day of bite, diagnosis of TMA was made from microangiopathic hemolytic picture in peripheral blood smear, thrombocytopenia and renal failure. Therapeutic plasma exchange with human albumin solution was started on a daily basis and after 3 cycles, patient's condition improved as shown by the laboratory parameters. Though this entity is not well defined, the supporting evidence is found in few reports of published literature. Hence, we propose plasma exchange as an adjunctive therapeutic option in post snake TMA.
