Assessment of serum and salivary adiponectin levels in newly diagnosed Type II diabetes mellitus patients.

J Oral Maxillofac Pathol 2020 May-Aug;24(2):245-250. Epub 2020 Sep 9.

Department of Oral Pathology, Narayana Dental College and Hospital, Nellore, Andhra Pradesh, India.

Background: Adiponectin, an adipocytokine, plays an important role in the development of Type 2 Diabetes Mellitus (T2DM) in obese and cardiovascular disease patients, with few studies having observed low plasma concentrations. Persistent low-grade inflammation, an important feature in T2DM and obesity, bears an indirect influence on insulin resistance and insulin secretion and is reflected by increased plasma levels of C-reactive protein (CRP). Thus, low levels of anti-inflammatory cytokine, adiponectin, depicts that inflammation could be the link between T2DM, obesity and adiponectin. Read More
