Hemolytic uremic syndrome after capnocytophaga canimorsus (DF-2) septicemia

A 66-year-old man developed a hemolytic uremic syndrome (HUS) with acute re nal failure, thrombocytopenia, fragmented red cells in the blood film and e levated serum LDH following a capnocytophaga canimorsus (DF-2) infection af ter a dog bite. He was treated with antibiotics, plasmapheresis and hemodia lysis. Although hematologic values improved, the patient remained hemodialy sis-dependent for six months. In the literature several cases of renal fail ure following capnocytophaga canimorsus septicemia have been described, cau sed by hypotension or disseminated intravascular coagulation (DIC). In our patient there were no signs of hypotension or extensive DIC. A few case rep orts described HUS and thrombotic thrombocytopenic purpura (TTP) following DF-2 sepsis.
