Objective: To review the evidence for discontinuing primary and secondary Pneumocystis jirovecii pneumonia (PJP) prophylaxis in HIV-infected patients with a CD4 count <200 cells/mm(3). Data Sources: We conducted a literature search in MEDLINE, EMBASE, Cochrane Library, Google Scholar, and the International Aids Society Library (up to August 2015) using the following key search terms: Pneumocystis jirovecii, pneumonia, human immunodeficiency virus, primary prophylaxis, secondary prophylaxis, and discontinuation. Study Selection and Data Extraction: All English-language studies that evaluated discontinuation of primary and/or secondary PJP prophylaxis in HIV-infected patients with CD4 count <200 cells/mm(3) were included. Data Synthesis: Five studies were identified, which varied in design, sample size, outcomes, and duration of follow-up. Three studies examined discontinuation of primary and secondary PJP prophylaxis; 1 study evaluated discontinuing primary PJP prophylaxis; and 1 study evaluated stopping secondary PJP prophylaxis. Two out of the 5 studies pooled data for all opportunistic infections. Overall, there was a low incidence of PJP among HIV-infected patients who discontinued primary PJP prophylaxis and were well controlled on antiretroviral therapy (ART). Conclusions: Discontinuation of primary PJP prophylaxis appears to be safe in patients on combination ART with a suppressed HIV viral load and a CD4 count >100 cells/mm(3). Additional data are needed to support the safety of discontinuing secondary PJP prophylaxis. Decisions to discontinue PJP prophylaxis in patients with a CD4 count <200 cells/mm(3) should be done on an individual patient basis, taking into consideration clinical factors, including ongoing adherence to ART.
