Antifungal Prophylaxis in Lung Transplant Recipients.

Abstract

Invasive fungal infection remains a serious postoperative complication in lung transplant recipients and is associated with significant morbidity and mortality. Although most lung transplant centers use antifungal prophylaxis, consensus on the strategy, choice of antifungal agent(s), route of administration, and duration of prophylaxis have not been established. This review provides an overview of the epidemiology and risk factors for common fungal infections seen in lung transplant recipients, evaluates the clinical efficacy and toxicity of the various antifungal agents used to prevent infection, and offers recommendations and opportunities for future research. Currently available data evaluating the efficacy of antifungal prophylaxis strategies is limited by a lack of prospective, randomized clinical trial data and variability in patient populations, prophylactic and immunosuppressive strategies, dosing, durations of use of antifungal agents, and definitions of invasive infection. There is controversy regarding significant risk factors for invasive fungal infection, which has limited the development and validation of targeted prophylactic strategies. Inhaled formulations of amphotericin B remain the most widely studied option for universal prophylaxis and have been shown to be effective in reducing the incidence of invasive Aspergillosis as compared with no prophylaxis. Concern over early postoperative extrapulmonary infection may suggest a benefit of initial prophylaxis with a systemic azole. Long-term use of systemic antifungals is not optimal due to emerging evidence of long-term toxicities. Multicenter, randomized trials are needed to ascertain the optimal prophylactic strategy in lung transplant recipients. New agents and delivery mechanisms may offer additional opportunities for comparative research.
