Hemolytic uremic syndrome following Hemiscorpius lepturus (scorpion) sting.
Scorpion envenomations are a public health problem in many countries. Scorpions are second only to snakes in causing human fatalities from envenomation. Species of scorpions capable of inflicting fatal stings are living in North and South Africa, the Middle East, India, America, Trinidad, and Tobago. Hemiscorpius lepturus (from the Hemiscorpiidae family) is the most medically important scorpion in Iran which accounts for 92% of all hospitalized scorpion sting cases. The venom from H. lepturus is primarily a cytotoxic agent and has hemolytic, nephrotoxic, and to some extent, hepatotoxic activities. We found a combination of microangiopatic hemolytic anemia, thrombocytopenia, and acute renal failure in a seven year-old female child who was referred to us with a 12 h history of bloody urine following a H. lepturus sting. Her blood smear showed fragmented erythrocytes and burr cells, leading us to a diagnosis of hemolytic uremic syndrome (HUS). This report highlights the importance of acceptable prophylaxis and therapeutic protocols for HUS in these patients.
