Impact of biliopancreatic diversion with duodenal switch on glucose homeostasis and gut hormones and their correlations with appetite.
Biliopancreatic diversion with duodenal switch (BPD/DS) results in lifelong changes in gastrointestinal physiology with unclear associations with appetite perception.. To explore mixed meal-induced changes in glucose homeostasis and gut hormones and their correlations with appetite perception.. University hospital.. Of 28 patients studied preoperatively (age: 38.4 ± 11.3 years; body mass index [BMI]: 56.5 ± 5.1 kg/m. BPD/DS resulted in 66.1% ± 23.3% excess BMI loss. Leptin was halved. Glucose and insulin levels were reduced, blunting a preoperative peak at 30 minutes, giving a lower homeostasis model assessment for insulin resistance (HOMA-IR; 13.9 versus 4.8). In contrast, reduced ghrelin and motilin concentrations were accompanied by pronounced peaks 20-30 minutes prior to meal responses. GIP was reduced, whereas GLP-1 and PYY responses were markedly increased, with an early postprandial peak (P < .05, for all). HOMA-IR correlated with insulin (r = .72) and GIP (r = .57). Postoperatively, satiety correlated with GLP-1 (r = .56), whereas the gastric motility index correlated with the desire to eat (r = .60), percentage excess BMI loss (r = -.55), and percentage total weight loss (r = -.49). Delta insulin, GLP-1, and leptin correlated positively with percentage total weight loss (r = .51, r = .48, and r = .58, respectively).. BPD/DS reduces leptin, HOMA-IR, and GIP while markedly increasing GLP-1 and PYY. This study marks the magnitude change in GLP-1 with additional effects of PYY as important factors for weight loss.

Treatment with interleukin-11 affects plasma leptin levels in inflamed and non-inflamed rabbits.
Treatment with the anti-inflammatory cytokine, interleukin-11 (IL-11), in rabbits with TNBS-colitis reduces tissue damage but does not normalize body weight loss despite an increase in plasma levels of motilin, known to stimulate food intake. We investigated whether IL-11 could increase plasma levels of the anorectic peptide, leptin in non-inflamed and inflamed rabbits. In addition, the effect of IL-11 and leptin on motilin mRNA expression in the T84 cell line was tested. Five days post-inflammation, weight loss amounted 10.7+/-1.2%, but plasma leptin and motilin levels were unaffected. During IL-11 treatment, weight loss remained and plasma leptin levels dose-dependently increased with 27+/-5% (4 microg/kg day) and 108+/-7% (720 microg/kg day). Motilin levels increased in parallel with 23+/-12% or 256+/-97%. In non-inflamed animals, a prompt decrease in weight (-11.9+/-1%) was observed after treatment with the highest dose of IL-11 and this was associated with an increase in plasma leptin (70+/-18%) and motilin levels (113+/-7%). Both IL-11 and leptin stimulated motilin mRNA expression in T84 cells with a different time profile. In conclusion, the increase in plasma leptin levels during IL-11 treatment induces wasting in normal rabbits and may be one of the major factors involved in the maintenance of body weight loss in rabbits with colitis. Increase of motilin expression by leptin may be part of a feedback mechanism.

Factors affecting outcome following proximal and distal intestinal resection in the dog: an examination of the relative roles of mucosal adaptation, motility, luminal factors, and enteric peptides.
In the clinical setting, resection of the ileum results in an inferior functional outcome compared to jejunal resection. This may be related to a greater adaptive capacity of the ileum, intrinsic structural and functional differences, or regional differences in motor and hormonal function. Our aim was to evaluate the relative contributions of these factors to functional outcome after resection of the proximal or distal intestine. Twenty-four dogs underwent either intestinal transection or 50% resection of the proximal or distal intestine. Studies (nutritional status, absorption, adaptation, motility, peptide levels) were performed every four weeks until the animals were killed at 12 weeks. Caloric intake was similar in all four groups. Weight loss was greater and more sustained after distal resection (DR). Serum cholesterol levels decreased significantly only in the DR group. While stool weight and moisture were similar, the DR animals had persistent, significant steatorrhea. Intraluminal anaerobic bacteria and SCFA concentrations were significantly greater in the ileum but were not influenced by resection. Intestinal remnant length increased to a greater extent after proximal resection (PR), but circumference increased to a similar extent after both resections. Villus height and crypt depth increased significantly only after PR. MMC frequency was similar in all four groups. In the DR animals 26% of migrating motor complexes (MMCs) originated within the remnant. The jejunal remnant of these animals had a dominance of cluster activity similar to the intact distal ileum. Following PR, the postprandial motilin response was decreased. After DR, there were transient increases in neurotensin and PYY. Of the various factors evaluated, mucosal adaptation and the intestinal motor response appear most likely to explain the inferior nutritional and absorptive outcome associated with resection of the distal small intestine.
