Efecto de metformina sobre la expresión del factor de necrosis tumoral-α, los receptores Toll-like 2/4 y la PCR ultra sensible en sujetos obesos con diabetes tipo 2
Background: The pharmacological action of metformin goes beyond mere glycemic control, decreasing markers of inflammation and contributing to the reduction of oxidative stress. Aim: To evaluate biochemical, anthropometric and pro-inflammatory markers in obese type 2 diabetic patients treated or not...

Aim: To evaluate biochemical, anthropometric and pro-inflammatory markers in obese type 2 diabetic patients treated or not with metformin. Patients and Methods: Obese patients with type 2 diabetes were invited to participate in the study if they were aged more than 40 years, were not receiving insulin, did not have cardiovascular diseases and were not taking anti-inflammatory drugs. A pharmacological history was taken and patients were stratified in two groups whether they were using metformin or not. A fasting blood sample was obtained to measure blood glucose, insulin, lipid levels, C reactive protein (hsCRP) and to isolate peripheral blood mononuclear cells. RNA was isolated from these cells to measure expression of tumor necrosis factor-α (TNF-α), Interleukin-6 (IL-6), nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kB), Toll-Like Receptor 2/4 (TLR 2/4) and beta-2-microglobulin (B2M). Results: Thirty participants were studied. Of these, 16 subjects aged 54.4 ± 5.5years were treated with metformin and 14 subjects aged 54.9 ± 6.4 years did not receive the drug. Participants receiving metformin had lower levels of hsCRP and lower mRNA relative abundance of TNF-α and TLR 2/4. There were no differences in glucose levels or lipid profile between both groups. Conclusions: Obese diabetic patients treated with metformin had lower levels of hsCRP expression of TNF-α and TLR 2/4, than their counterparts not receiving the drug.info:eu-repo/semantics/openAccessSociedad Médica de SantiagoRevista médica de Chile v.140 n.11 20122012-11-01text/htmlhttp://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0034-98872012001100001es10.4067/S0034-98872012001100001 |
