Chronic obstructive pulmonary disease (COPD) is characterized by chronic inflammation of the airways and/or damage to the lungs which leads to progressive impairment in airflow and the ability to breathe. COPD affects 6 to 20% of the US population and is among the leading causes for mortality in men and women. While COPD is principally a pathology of the airway, skeletal muscle wasting is a widely recognized comorbidity contributing to frequent and expensive hospital visits.
Hospital readmission rates among COPD patients are high and the majority of the readmissions are considered preventable. The reasons COPD patients lose muscle are still poorly understood although reduced pulmonary function has been associated with reduced testosterone levels. Muscle building treatments, including testosterone therapy, with and without exercise, have consistently been shown to promote improvements in body composition, exercise capacity, and health related quality of life of COPD patients.
The overall goal of this investigation is to provide an effective long-term treatment strategy that prevents the advancement of COPD in men and women through a safe, cycled administration of testosterone during the early stages of disease.
Male and female COPD patients participating in a 12 week pulmonary rehabilitation program at the University of Texas Medical Branch enrolled in the study will be randomized into either placebo or testosterone enanthate (100mg men, 25mg women) treatment. Testosterone and placebo will be given in a cyclic fashion during the pulmonary rehabilitation with single injections given on weeks 2, 3, 6, 7, 10 and 11. Baseline (during week 1 of rehabilitation) and post (during week 12 of rehabilitation) study testing will measure the effectiveness of testosterone on several measures listed in the outcome section.
