The effects of antifungal therapy on the recurrence of aspergillus infection after pulmonary aspergilloma resection: a study protocol for a single-center, prospective, non-blind, randomized, 24-month, parallel group study

Abstract

Background: In recent years, the incidence of pulmonary aspergilloma has increased. The harm of aspergilloma is life-threatening massive hemoptysis, and the conventional treatment is surgical treatment. However, whether the antifungal treatment after surgery is required and the course of treatment before and after surgery are still unclear. Methods: In this study, patients with pulmonary aspergilloma confirmed pathologically after surgery will be selected as subjects to conduct a single-center, randomized, parallel grouping, prospective, 2-year clinical study. Through regular visits, the recurrence of aspergillus infection, quality of life, lung function indicators, safety of antifungal therapy and other indicators were recorded to evaluate the recurrence risk of aspergillus infection and safety of antifungal agents. Cox proportional risk regression model was used to analyze the influencing factors of antifungal therapy on aspergillus infection recurrence after aspergillus bulbectomy. Cox multiple regression model was used for optimal model fitting, and regression coefficient (β), relative risk (RR) and 95% confidence interval of RR were calculated. Discussion: The study will explore whether antifungal therapy could improve the quality of life, reduce the recurrence of aspergillus infection, and ultimately improve the prognosis of patients with aspergilloma. The study results will provide high-quality evidence-based medical evidence for the formulation, revision and optimization of international and domestic clinical guidelines and expert consensus on chronic aspergillus lung disease, effectively improve the clinical treatment effect of aspergilloma, and form the latest concept of diagnosis and treatment of aspergilloma. Trial registration: The trial was registered on the Chinese Clinical Trial Registry website (https://www.chictr.org.cn/showprojen.aspx?proj=33231). Registration number: ChiCTR1800019990.
