Duodenal-Jejunal Bypass Liner (DJBL) Improves Cardiovascular Risk Biomarkers and Predicted 4-Year Risk of Major CV Events in Patients with Type 2 Diabetes and Metabolic Syndrome.

Abstract

The duodenal-jejunal bypass liner (DJBL) represents a novel endoscopic minimally invasive treatment option for obesity-associated type 2 diabetes (T2D), affecting body weight and metabolic control. Until now, the effects of DJBL on cardiovascular risk have never been investigated. Between 2012 and 2017, 71 patients with T2D and metabolic syndrome (MS) were recruited for implantation of DJBL for 9-12months. Within DJBL treatment and a follow-up period of 6months, patients were analysed for dynamics of cardiovascular biomarkers. Overall cardiovascular risk was estimated by the ADVANCE Risk Engine at time of implantation, explantation and 6months after explantation of DJBL. DJBL-induced weight loss and improvements in blood sugar control were accompanied by significant decreases of the cardiovascular biomarkers high-sensitive CRP, lipoprotein-associated phospholipase A2 and small dense lipoprotein fraction LDL-4 (p = 0.001, p < 0.001 and p = 0.04, respectively). Estimated overall cardiovascular risk decreased significantly after DJBL implantation and remained stable within 6months after explantation. In addition to beneficial effects of DJBL on weight loss, glycaemic control and lipid parameters in patients with MS, this is the first study that could further reveal significant impact on serological cardiovascular biomarkers and estimated CV risk, suggesting putative protective effects of DJBL on CV outcome.
