title: [Risk of nosocomial Pneumocystis carinii pneumonia in immunosuppressed patients non-infected by human immunodeficiency viruses].
abstract: We report four cases of Pneumocystis carinii pneumonia (PCP) in Human Immunodeficiency Virus (HIV)-seronegative patients. Two of them had been hospitalized for polymyositis treatment near AIDS patients, respectively 1 and 4 months before PCP. The two others suffered from localized cancer. Their evolution was complicated by respiratory distress and death in two of them. A telephone survey among 19 hospital units yielded nine cases of similar patients. They were only observed in wards caring for AIDS patients at the same time, thus raising the question of a possible nosocomial transmission of PCP between AIDS patients and immunocompromised HIV-seronegative patients. This adds to the growing concern for hospital-acquired infections, including resistant tuberculosis and other opportunistic pathogens. We propose some practical measures to limit this risk by simple means such as no-contact between at-risk populations, enhanced disinfection procedures of the rooms and masking of the coughing PCP patients.
