SO Int Conf AIDS. 1994 Aug 7-12;10(1):190 (abstract no. PB0187). Unique Identifier : AIDSLINE ICA10/94369639 AB BACKGROUND: Thrombotic microangiopathies (TMA) are characterized by a pentad of microangiopathic hemolytic anemia, thrombocytopenia, fever, central nervous system abnormalities, and renal dysfunction. 2 distinct forms of TMA exist: Thrombotic thrombocytopenic purpura (TTP), characterized by minimal kidney dysfunction but severe neurological impairment and HUS, usually without neurological abnormalitics. Infection with E. coli producing a shiga-like toxin (most notably E. coli 0157:H7) has been shown to be the major cause of HUS. The association of TMA with HIV infection has been documented in more than 50 cases. Most cases are consistent with a diagnosis of TTP. E. coli 0157:H7 associated HUS, however, seems to be extremely rare with only one reported case in the literature. We present a case of HUS caused by E. coli 0157:H7 in an AIDS-patient, who was refractory to a variety of therapeutic measures. CASE REPORT: A 33-year old white homosexual with AIDS and a CD4 count of 20 cells/microliter was admitted because of bloody diarrhea, fevers and intermittent nausea and vomiting. Lab. values: LDH 1300 U/l, serum creatinine 2.3 mg/dl, BUN 51 mg/dl, hemoglobin 9.1, WBC 2.55, platelets 24, Haptoglobin < 0.4 g/l. Bone marrow cytology was normal. Urinalysis was positive for protein and hemoglobin +. Multiple schistocytes were seen on blood smears. A stool culture grew enterohemorrhagic escherichia coli (VTEC) which produced a shiga-like toxin (SLK 2). Serotyping classified the VTEC as 0157:H7. The patient was diagnosed with HUS. Despite vigorous treatment with plasmapheresis, iv IgG, heparin, corticosteroids and vincristine hemolysis never subsided and the patient died 3 months later. DISCUSSION: Because anemia, thrombocytopenia, elevation of LDH, uremia, and neurological abnormalities are not uncommon in HIV infected patients and can be caused by many different diseases, TMAs may have been overlooked in some patients reported in the literature despite a typical presentation. Clinicians caring for patients with HIV infection must be aware of the risk of TMAs in these patients and AIDS-patients with bloody diarrhea should routinely be cultured for VTEC.
