Statins have anti-inflammatory effects in the lung and vasculature that might benefit cardiopulmonary dysfunction in HIV. These agents have a long history of clinical use in cardiovascular disease and are currently being investigated as disease-modifying drugs for HIV, COPD, and PH. In preliminary analyses, the investigators have found that HIV+ individuals who received statin therapy within the past year were significantly less likely to have impaired DLco and had lower pulmonary artery pressures, lower NT-proBNP, lower peripheral cytokines, and fewer sputum neutrophils despite being older and having a greater smoking history than those not using statins.
