A Case of Hemolytic Uremic Syndrome Caused by Escherichia coli O8: Case Report / 대한소화기내시경학회지

ABSTRACT

Since 1982, many countries have reported outbreaks or sporadic cases by enterohemorrhagic Escherichia coli (E. coli) serogroup strains, mainly E. coli O157 H7. Hemorrhagic E. coli induces hemolytic uremic syndrome (HUS) in 10 to 15% of cases in infants and young chilidren. HUS is a clinical syndrome of hemolytic anemia, acute renal failure, and thrombocytopenia. We experienced a case of E. coli O8 as the causative organism of hemorrhagic colitis and hemolytic uremic syndrome in 16 year-old man. Hemorrhagic colitis was diagnosed by the sigmoidoscopy and E. coli O8 was identified in the stool culture. Hemolytic uremic syndrome was clinically diagnosed. A conservative management including total parenteral nutrition, plasma exchange transfusion, hemodialysis and continuous arteriovenous hemofiltration with dialysis resulted in a complete recovery of the patient. We herein report this manifestations of E. coli O8 and discuss the therapeutic issues related to hemorrhagic colitis and hemolytic uremic syndrome.
