BACKGROUND: Intravenous micafungin has been reported as a treatment alternative in patients with chronic pulmonary aspergillosis (CPA) where long-term oral triazole therapy is unfeasible.
OBJECTIVES: We evaluated the safety and efficacy of micafungin administered via the outpatient parenteral antimicrobial therapy (OPAT) service for the treatment of CPA.
METHODS: We included all CPA patients who received micafungin via OPAT between April 2016 and March 2018. Data on adverse events and line-related complications, and Quality of Life (QoL) scores at the start of micafungin course and 3 months later were extracted.Improvements in QOL were defined as an improvement of ≥4 points in at least one modality (symptom, impact, activity, total) in the St George’s QOL score. A stable QOL score was defined as a change in score of less than 4 points in either direction whilst deterioration was defined as an increase of ≥4 points.
RESULTS: There were 20 OPAT episodes involving 18 patients with a median duration of micafungin therapy of 21 (range: 4-248) days. Improvement or stability in the symptoms, activity, impact and total score was seen in 14 (78%), 12 (67%), 9 (50%) and 9 (50%) of the patients respectively. However, half of the patients reported deterioration in the impact domain and total scores. By self-assessment, patients who categorized themselves as “poor” was comparable at the start of OPAT and at 3 months (43% vs. 50%, McNemar’s p=0.7). Adverse events attributable to micafungin were recorded in 3 (14.3%) episodes.
CONCLUSIONS: Micafungin may be safely administered via an OPAT service. Micafungin therapy was associated with an improvement or stability in QoL scores in at least 50% of the patients across the 4 domains.
