Six Months of Treatment with the Endoscopic Duodenal-Jejunal Bypass Liner Does Not Lead to Decreased Systemic Inflammation in Obese Patients with Type 2 Diabetes

Obesity is associated with chronic low-grade systemic inflammation. Bariatric surgery has been shown to reduce this inflammation. Here, the effect of a nonsurgical bariatric technique, the duodenal-jejunal bypass liner (DJBL), on systemic inflammation was investigated. Seventeen obese patients with type 2 diabetes were treated with the DJBL for 6 months. Plasma C-reactive protein (CRP), myeloperoxidase (MPO), interleukin-6 (IL-6), and tumor necrosis factor alpha (TNF-α) were determined prior to and during DJBL treatment. Three months after initiation of DJBL treatment, TNF-α levels had increased from 1.8?±?0.1 to 2.1?±?0.1 pg/mL, whereas IL-6 increased from 2.7?±?0.3 to 4.0?±?0.5 pg/mL (both p?p?=?ns compared to baseline). In the current study, 6 months of endoscopic DJBL treatment did not lead to decreased systemic inflammation.
