Impact of Bariatric Surgery on Circulating Inflammatory and Pro-vascular Progenitor Cell Populations.
In Brief
An observational study evaluating Bariatric (weight loss) surgery for Obesity, Morbid and 2 related conditions. Completed, enrolled 38 participants across 1 site.
Detailed Summary
Obesity and diabetes are linked to increased risk for health problems such as heart attack, stroke, and death. At the cellular level, obesity and diabetes increase levels of harmful inflammatory cells (M1 macrophages) and decreases levels of protective stem cells (circulating progenitor cells) in the blood. Bariatric (weight loss) surgery is an effective treatment that leads to significant weight loss and improved health in patients with obesity. However, it is unknown if weight loss surgery also replenishes healthy stem cells and decreases inflammatory cells in the body. Therefore, the purpose of this research study is to compare levels of these stem and inflammatory cells before and after bariatric surgery, and to compare to a control group of healthy normal weight participants. The investigators anticipate that inflammatory cell levels will be reduced and stem cell levels and function will be restored after bariatric surgery, similar to levels of healthy normal weight individuals.

Interventions
Surgical intervention for weight reduction, whereby the stomach is resected and the gastrointestinal tract is rerouted in the case of Roux-en-y gastric bypass, or the stomach is only resected in the case of sleeve gastrectomy.
