NCT04941573
This study will use Magnetic Resonance Imaging (MRI) to study the lungs of 90 volunteers using the inhaled contrast agent, hyperpolarized xenon-129. Once inhaled, this gas can provide information to imagers regarding lung functionality across specific regions of the lungs by assessing the replacement of air during the normal breathing cycle, how much oxygen is in the airspaces, and if the natural spongy tissue structure has been compromised by lung disease. Of the 90 subjects, 70 will be patients who received lung transplantation from the Penn/Temple Lung Transplant Teams and are receiving follow up treatment at HUP or TUH, 10 will be healthy control subjects who participated favorably in our HP 129Xe imaging protocol, and 10 will be patients who have been diagnosed with chronic obstructive pulmonary disease (COPD)-preferentially recruited from the Temple University COPDGene cohort, who have never undergone a lung transplant. 20 of the lung transplant recipient subjects will be patients who have received a recent clinical diagnosis of chronic lung allograft dysfunction (CLAD) prior to enrollment in our study, while the other 50 will have recently undergone their initial transplant surgery at the time of enrollment.

The main aim of this study is to find out the long-term safety and effectiveness profile of recombinant human parathyroid hormone (1-84) (rhPTH\[1-84\]) treatment in participants with chronic hypoparathyroidism under conditions of routine clinical practice. Participants will be treated according to their clinic's standard practice determined by the treating doctors. Each participant will fill out a study questionnaire during a routine doctor visit.
