“A Study of Pleiotropic Pioglitazone Effects on the Alcoholic Lung (APPEAL Study)”
This study is a single center, open-label, randomized clinical trial to determine the effect of pioglitazone (PIO) treatment on alveolar macrophage immune function, redox stress, and NADPH oxidase expression in outpatient alcoholic subjects. The researchers will recruit a cohort of otherwise healthy patients with an alcoholic use disorder from the Substance Abuse Treatment Program at the Atlanta Veterans Affairs (VA) Medical Center and randomize them to receive the usual treatment for two to four weeks or to the usual treatment plus PIO treatment for two to four weeks. There will also be a healthy control group (matched on age, gender, and smoking status) that will receive no treatment. To measure the effect of pioglitazone, participants will undergo a bronchoscopy before taking the study drug and then again 2-4 weeks later to look for changes. The bronchoscopy will allow researchers to obtain fluid from the lungs to see how well their immune cells respond to bacteria by determining phagocytic capacity.
Drug - Pioglitazone
Participants will take 30 mg of pioglitazone once daily for a total of two to four weeks for those randomized to therapy, until the next bronchoscopy is performed. Participants will receive 14 to 28 tablets of active pioglitazone, which is enough to complete the minimum 14-day course of therapy.
