Abstract/Text
BACKGROUND: Pneumocystis jirovecii pneumonia (PCP) is a life-threatening infection for immunocompromised individuals. Robust data and clear guidelines are available for prophylaxis and treatment of human immunodeficiency virus (HIV)-related PCP (HIV-PCP), yet few data and no guidelines are available for non-HIV-related PCP (NH-PCP). We postulated that prevention and inpatient management of HIV-PCP differed from NH-PCP.
METHODS: We performed a retrospective case review of all pathologically confirmed cases of PCP seen at the University of Alabama Medical Center from 1996 to 2008. Data on clinical presentation, hospital course, and outcome were collected using a standardized data collection instrument. Bivariate analysis compared prophylaxis, adjunctive corticosteroids, and clinical outcomes between patients with HIV-PCP and NH-PCP.
RESULTS: Our analysis of the cohort included 97 cases of PCP; 65 HIV and 32 non-HIV cases. Non-HIV cases rarely received primary prophylaxis (4% vs. 38%, P = 0.01) and received appropriate antibiotics later in the course of hospitalization (5.2 days vs. 1.1 days, P < 0.005). Among transplant patients, NH-PCP was diagnosed a mean of 1066 days after transplantation and most patients were on low-dose corticosteroids (87%) at the time of disease onset. No significant differences in adjunctive corticosteroid use (69% vs. 77%, P = 0.39) and 90-day mortality (41% vs. 28%, P = 0.20) were detected.
CONCLUSIONS: Patients who have undergone organ or stem cell transplant remain at risk for PCP for many years after transplantation. In our cohort, patients who developed NH-PCP were rarely given prophylaxis, and initiation of appropriate antibiotics was significantly delayed compared to cases of HIV-PCP. Medical providers should be aware of the ongoing risk for NH-PCP, even late after transplantation, and consider more aggressive approaches to both prophylaxis and earlier empirical therapy for PCP.
