Lymphangioleiomyomatosis (LAM) Registry

Lung Diseases, Lymphangiomyomatosis

To establish a registry of individuals with LAM by forming a consortium of six clinical centers and referring physicians who treat LAM patients.

BACKGROUND: LAM is a rare multi-system disease that can affect the lungs of young women, is of uncertain cause, is usually progressive, and can cause debilitating lung disease which may be corrected with lung transplantation. Several hundred women with the disease have been identified, largely through a LAM Foundation in Cincinnati, Ohio. DESIGN NARRATIVE: The Data and Coordinating Center is located at the Cleveland Clinic Foundation. The registry has six major clinical centers: Cleveland Clinic Foundation, Mayo Clinic-Rochester, National Heart, Lung, and Blood Institute, National Jewish Medical and Research Center, New England Medical Center, and Stanford University Medical Center. Data and lung tissue collected by the registry will be used to characterize the clinical features and natural history of the disease and to determine the efficacy of lung transplantation in this disorder. Eligible patients are to be seen yearly for up to 4 years at the Clinical Centers or, in some cases, by individual referring physicians. Tissue collected by the LAM Registry will be stored at a central NHLBI repository. Outcome events include measures of pulmonary function (eg, spirometry and, when available, lung volumes and diffusing capacity), arterial blood gases or oximetry, walking and resting oxygen titration, cardiopulmonary stress testing, cause-specific mortality, functional status, and clinical events associated with lung transplantation. The Office of Research on Women's Health provided funding in FY 1997 in the amount of $100,000. The study completion date listed in this record was obtained from the End Date entered in the Protocol Registration and Results System (PRS) record.
