Abstract

PURPOSE:

The outcomes and predictors of mortality from Pneumocystis pneumonia (PCP) in HIV-negative patients requiring mechanical ventilation (MV) for respiratory failure were evaluated.

MATERIALS AND METHODS:

This retrospective observational study enrolled 48 patients with PCP requiring MV in the medical intensive care unit (ICU). Multiple logistic regression analysis was used to identify independent predictors of in-hospital mortality.

RESULTS:

The main conditions underlying the PCP were malignancies (60%) or post solid organ transplant (35%). Excluding four patients whose initial treatment was changed due to adverse reactions, 21 (44%) of 44 patients did not respond to the initial treatment. During the ICU stay, additional complications developed: shock in 22 (46%), ventilator-associated pneumonia in 16 (33%), and acute kidney injury in 15 (31%). Ultimately, 31 (65%) patients died while hospitalised. In multivariate analysis, hospital mortality was independently associated with severity of illness on ICU admission, failure of initial antimicrobial treatment for PCP, and newly developed shock during ICU stay.

CONCLUSIONS:

PCP in HIV-negative patients requiring MV for respiratory failure remains a serious illness with high mortality. Failure of the initial antimicrobial treatment for PCP as well as severity of illness was independent predictors of poor outcomes.
