OBJECTIVES: Limited data exist on the optimal treatment duration for chronic pulmonary aspergillosis (CPA). We investigated the treatment outcome and recurrence rate according to treatment duration in CPA patients.
METHODS: A total of 196 patients who completed at least 6 months of antifungal therapy (99% oral itraconazole) and achieved favorable treatment responses were analyzed. A Cox's proportional hazards regression model was used to adjust for potential confounding factors in the association between the duration of antifungal therapy (6-12 months vs. ≥ 12 months) and recurrence.
RESULTS: All patients were treated with antifungal agents for at least 6 months (median: 12.5, interquartile range: 8.5-18.4 months) and categorized into 6-12 months group (79/196, 40%) and ≥ 12 months group (117/196, 60%). The 6-12 months group had significantly higher recurrence rates owing to CPA aggravation after the completion of treatment compared with the ≥ 12 months group (51% vs. 25%, P = 0.003). In a Cox's proportional hazards regression model, treatment duration ≥ 12 months was independently associated with a lower risk of recurrence (adjusted hazard ratio: 0.48, 95% confidence interval: 0.28-0.80).
CONCLUSIONS: Our data suggest that prolonging antifungal therapy beyond 12 months could reduce the recurrence rate in CPA patients.
