BACKGROUND: Allergic bronchopulmonary aspergillosis (ABPA) is a rare disease that affects patients with asthma or cystic fibrosis. Its debilitating course has led to the search for new treatments, including antifungals and monoclonal antibodies.
OBJECTIVE: To evaluate the efficacy and safety of antifungal treatments in patients with ABPA and asthma or cystic fibrosis.
METHODS: We performed a systematic review of the literature on the effects of antifungal agents in ABPA using three biomedical databases. Quality assessment was performed using the GRADE methodology and, where appropriate, studies with comparable outcomes were pooled for meta-analysis.
RESULTS: Thirty-eight studies - 4 randomized controlled trials and 34 observational studies -met the eligibility criteria. The antifungal interventions described were itraconazole, voriconazole, posaconazole, ketoconazole, natamycin, nystatin, and amphotericin B. An improvement in symptoms, frequency of exacerbations, and lung function was reported in most of the studies and was more common with oral azoles. Antifungals also had a positive impact on biomarkers and radiological pulmonary infiltrates, but adverse effects were also common. The quality of the evidence supporting these results was low or very low due to a shortage of controlled studies, heterogeneity between studies, and potential bias.
CONCLUSIONS: Antifungal interventions in ABPA improved patient and disease outcomes in both asthma and cystic fibrosis. However, the recommendation for their use is weak and clinicians should therefore weigh up desirable and undesirable effects on a case-by-case basis. More studies with a better methodology are needed, especially in cystic fibrosis, to increase confidence in the effects of antifungal treatments in ABPA. This article is protected by copyright.
