Official title
Effect of High-Dose Vitamin D3 on Alveolar Macrophage Function, LL-37, and Oxidative Stress in Smokers and Non-Smokers With and Without HIV
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Supplementation with vitamin D improves HIV+ macrophages phagocytosis in vitro. There is evidence to suggest that administering vitamin D can in fact improve immune function in individuals. The study will evaluate the impact of high dose vitamin D in HIV+ smokers' and HIV- smokers' in vivo. The primary goal is to improve innate immune host response to infection in patients already at high risk by virtue of HIV and smoking status.
