Thrombotic microangiopathy (TMA), which includes the spectrum of hemolytic uremic syndrome and thrombotic thrombocytopenic purpura, is an uncommon complication of hump-nosed pit viper envenomation. We describe 4 cases of TMA following hump-nosed pit viper (Hypnale spp) bites in Sri Lanka. The first case is a typical TMA that spontaneously resolved with supportive treatments. The second and third cases are related to hemolytic uremic syndrome complicated with acute kidney injury that required hemodialysis. The fourth case is thrombotic thrombocytopenic purpura associated with acute kidney injury that required hemodialysis and therapeutic plasma exchange. For each patient we describe the circumstances of the bite, clinical features, laboratory findings, and management.

Thrombotic thrombocytopenic purpura (TTP) is a rare, fatal disorder which could be caused by autoimmune diseases. However, TTP secondary to Sjögren syndrome (SS) is extremely rare.

Diseases that result in THROMBOSIS in MICROVASCULATURE. The two most prominent diseases are PURPURA, THROMBOTIC THROMBOCYTOPENIC; and HEMOLYTIC-UREMIC SYNDROME. Multiple etiological factors include VASCULAR ENDOTHELIAL CELL damage due to SHIGA TOXIN; FACTOR H deficiency; and aberrant VON WILLEBRAND FACTOR formation.
An acquired, congenital, or familial disorder caused by PLATELET AGGREGATION with THROMBOSIS in terminal arterioles and capillaries. Clinical features include THROMBOCYTOPENIA; HEMOLYTIC ANEMIA; AZOTEMIA; FEVER; and thrombotic microangiopathy. The classical form also includes neurological symptoms and end-organ damage, such as RENAL FAILURE.
An hereditary hemolytic uremic syndrome associated with variations in the gene that encodes COMPLEMENT FACTOR H, or the related proteins CFHR1 and CFHR3. Disease often progresses to CHRONIC KIDNEY FAILURE without the prodromal symptoms of ENTEROCOLITIS and DIARRHEA that characterize typical hemolytic uremic syndrome.
An ADAMTS protease that contains eight thrombospondin (TS) motifs. It cleaves VON WILLEBRAND FACTOR to control vWF-mediated THROMBOSIS. Mutations in the ADAMTS13 gene have been identified in familial cases of PURPURA, THROMBOTIC THROMBOCYTOPENIC and defects in ADAMTS13 activity are associated with MYOCARDIAL INFARCTION; BRAIN ISCHEMIA; PRE-ECLAMPSIA; and MALARIA.
A syndrome that is associated with microvascular diseases of the KIDNEY, such as RENAL CORTICAL NECROSIS. It is characterized by hemolytic anemia (ANEMIA, HEMOLYTIC); THROMBOCYTOPENIA; and ACUTE RENAL FAILURE.
Blood is a specialized bodily fluid that delivers necessary substances to the body's cells (in animals) – such as nutrients and oxygen – and transports waste products away from those same cells. In vertebrates, it is composed of blo...
