Insulin may reduce several inflammatory factors induced by bacterial infection
Date:9/8/2010

,

In addition, the endotoxin induced a rapid rise in several destructive and inflammatory factors, including reactive oxygen species (free radicals) and products of nitric oxide and fat metabolism. The insulin infusion led to total elimination of several pro-inflammatory factors and to a significant reduction in generation of reactive oxygen species and the products of fat metabolism.

Paresh Dandona, MD, PhD, UB distinguished professor of medicine and senior author on the study, says this study confirms the expectations arising out of the researchers' initial discovery of the anti-inflammatory effect of insulin.

"This study lays the foundation for further studies based on insulin infusion and the normalization of blood glucose concentrations in patients with endotoxemia and septicemia," says Dandona.

"Our endocrinology group demonstrated previously that insulin also has anti-inflammatory and cardioprotective effects in patients who had a heart attack, and we currently are conducting a study on the potential beneficial effects of insulin on acute stroke.

"Clearly, insulin may emerge with roles beyond those conceived when it was discovered in 1921 as a metabolic hormone, and has since been used for the treatment of diabetes to lower and control blood glucose concentrations," Dandona notes.
