[Pneumothorax in cystic fibrosis: intrapleural instillation of Atabrine]

Intrapleural instillation of quinacrine HC1 (Atabrine) was used to treat spontaneous pneumothorax in 2 young men, aged 26 and 36 years, respectively, with advanced pulmonary disease due to cystic fibrosis. Pneumothorax did not recur until 1 year later in 1 case and 2 years later in the other. This mode of therapy for pneumothorax provides a valuable alternative to surgery for the patient with cystic fibrosis, severe lung disease and marginal pulmonary reserve. Quinacrine sclerosis should be considered for management of pneumothorax in cystic fibrosis because of the high rate of recurrence. However, caution should be exercised since heart-lung transplantation cannot be performed after pleural sclerosis.
