Abstract

Arginine vasopressin (AVP) was suggested to contribute to cardiovascular risk and type 2 diabetes in patients with metabolic syndrome. The proinflammatory cytokine interleukin (IL)-1 is able to induce AVP secretion and plays a causal role in cardiovascular mortality and type 2 diabetes. We investigated in two studies whether copeptin levels - the surrogate marker for AVP - are regulated by IL-1-mediated chronic inflammation in patients with metabolic syndrome. Study A was a prospective, interventional, single-arm study (2014-2016). Study B was a randomized, placebo-controlled, double-blind study (2016-2017). n = 73 (Study A) and n = 66 (Study B) adult patients with metabolic syndrome were treated with 100 mg anakinra or placebo (only in study B) twice daily for 1 day (study A) and 28 days (study B). Fasting blood samples were drawn at day 1, 7, and 28 of treatment for measurement of serum copeptin. Patients with chronic low-grade inflammation (C-reactive protein levels ≥2 mg/L) and BMI >35 kg/m2 had higher baseline copeptin levels (7.7 (IQR 4.9-11.9) vs 5.8 (IQR 3.9-9.3) pmol/L, Pinflamm = 0.009; 7.8 (IQR 5.4-11.7) vs 4.9 (IQR 3.7-9.8) pmol/L, PBMI = 0.008). Copeptin levels did not change either in the anakinra or in the placeb...Continue Reading

Biomarkers for Type 2 Diabetes

Biomarkers can help understand chronic diseases and assist in risk prediction for prevention and early detection of diseases. Here is the latest research on biomarkers in type 2 diabetes, a disease in which the body is unable to produce or properly use insulin.
