Özet

Endothelial protein C receptor (EPCR) is primarily localized on the endothelial cells of large blood vessels and is very low or absent in the microvascular endothelium of most tissues. EPCR augments the thrombin/thrombomodulin-dependent activation of protein C by 5- to 20-fold. EPCR appears to be physiologically significant in the control of blood coagulation and inflammation and in the host response to gram-negative sepsis. Here, the authors report an 8-month-old boy, who had chronic liver disease due to undetermined cause. He had Staphylococcus aureus and Candida albicans sepsis and died due to gastrointestinal, lung, and peritoneal bleeding during follow-up. Serum soluble EPCR level of the patient was high (225 ng/mL) during sepsis. A homozygous 23-bp insertion of EPCR gene was demonstrated. This case indicates the importance the EPCR gene plaus in pediatric sepsis. Homozygous 23-bp insertion of the EPCR gene may be associated with a tendency to sepsis and poor outcome.
