Abstract

OBJECTIVE:

Bariatric procedures that exclude the proximal small intestine lead to significant weight loss which is probably mediated by changes in hormones that alter appetite, such as peptide YY (PYY), ghrelin, cholecystokinin (CCK), and leptin. Here, the effect of the non-surgical duodenal-jejunal bypass liner (DJBL) on concentrations of hormones implicated in appetite control was investigated.

SUBJECTS:

A two-center prospective study was conducted between January and December 2010. Seventeen obese subjects with type 2 diabetes were treated with the DJBL for 24 weeks. Fasting concentrations of leptin and meal responses of plasma PYY, CCK, and ghrelin were determined prior to and after implantation of the DJBL.

RESULTS:

At baseline, subjects had an average body weight of 116.0 ± 5.8 kg. One week after implantation, subjects had lost 4.3 ± 0.6 kg (p < 0.01), which progressed to 12.7 ± 1.3 kg at week 24 (p < 0.01). Postprandial concentrations of PYY and ghrelin increased (baseline vs. week 1 vs. week 24 PYY: 2.6 ± 0.2 vs. 4.1 ± 0.4 vs. 4.1 ± 0.7 nmol/L/min and ghrelin: 7.8 ± 1.8 vs. 11.0 ± 1.8 vs. 10.6 ± 1.8 ng/mL/min, all p < 0.05). In parallel, the CCK response decreased (baseline vs. week 1 vs. week 24: 434 ± 51 vs. 229 ± 52 vs. 256 ± 51 pmol/L/min, p < 0.01). Fasting leptin concentrations also decreased (baseline vs. week 24: 98 ± 17 vs. 53 ± 10 ng/mL, p < 0.01).

CONCLUSIONS:

DJBL treatment induces weight loss paralleled by changes in concentrations of hormones involved in appetite control.
