title: [Pneumocystis jirovecii pneumonia in non-HIV infected patients: a study of 41 cases].
abstract: BACKGROUND
  The increasing use of immunosuppressive and cytotoxic therapies leads to a growing number of opportunistic infections especially Pneumocystis jirovecii pneumonia (PCP). The purpose of our study was to describe the population involved, and to assess clinical, biological, and mortality data.
  
  
  METHODS
  We collected retrospectively the whole medical file of all PCP cases diagnosed in non-HIV infected patients, in two French University Hospitals in the last decade (1999-2009). Diagnosis was made on standard coloration and/or immunofluorescence analysis of bronchoalveolar lavage fluid (BAL).
  
  
  RESULTS
  Forty-one patients were included in the study, mean age 56 (±12.5) years, sex ratio 0.71 men/woman. Underlying diseases were as follow: 12 patients (29%) were renal transplant recipients, 13 (32%) were treated for solid cancers, and 16 (39%) suffered from various diseases (three allogenic bone-marrow transplantation, 11 hematological malignancies, one pulmonary transplantation, one vasculitis). Twelve patients died (i.e. 29%). Median lymphocyte count was 542/mm(3). More than 85% patients received corticosteroids at a median cumulative 6-month dose of 2700mg. Seven patients (17%) had a PCP prophylaxis. Clinical worsening at day 5 (P<0.003), poor control of the underlying disease (P<0.015), WHO performans status superior than 2 (P<0.025), high temperature (P<0.04), and high oxygen flow (P<0.042) were linked to a poor prognosis.
  
  
  CONCLUSIONS
  The prognosis factors found are mostly linked to the patients' clinical severity. We would like to highlight: first, near to 30% mortality rate, secondly, a lack of prophylaxis in 34 patients, reflecting the difficulty to define PCP's risk in non HIV-infected patients.
