Sleep Apnea in Patients with MGUS and MM

Description

This study involves patients with plasma cell dyscrasia including monoclonal gammopathy of undetermined significance (MGUS) or multiple myeloma (MM), with and without sleep apnea, who are providing bone marrow specimens. Specimens will be obtained at the time that patients undergo a standard-of-care procedure in order to minimize discomfort and reduce any risk.Obesity is a risk factor for the development of MM, although the mechanisms that link obesity and MM are unclear. Obesity, in turn, is closely associated with obstructive sleep apnea. Interestingly, the key risk factors for both sleep apnea and MM are overlapping (age, sex, race and body mass index). During the apnea, or cessation of normal breathing, arterial oxygen saturation falls. This can occur as often as 60 times per hour, resulting in chronic intermittent hypoxia (CIH). In preliminary studies, investigators exposed C57BL/6 mice, that are typically resistant to engraftment of malignant plasma cells to CIH, followed by inje
