Changes in the intestinal microbial community and some metabolic disturbances, including obesity and type2 diabetes, are related. Glucagon-like peptide-1 (GLP-1) regulates glucose homeostasis. Microbiota have been linked to incretin secretion. Antibiotic use causes changes in microbial diversity and composition. Our aim was to evaluate the relationship between microbiota changes and GLP-1 secretion. A prospective case-control study with a -positive patient model involving subjects under eradication therapy (omeprazole, clarithromycin, and amoxicillin). Forty patients with infection and 20 matched participants, but negative for antigen. Patients were evaluated before and two months after treatment. We analyzed anthropometric measurements, carbohydrate metabolism, lipid profile, and C-reactive protein. Gut microbiota composition was analyzed through 16S rRNA amplicon sequencing (IlluminaMiSeq). Eradication treatment for decreased bacterial richness (Chao1, 0.041). Changes in gut microbiota profiles were observed at phylum, family, genus and species levels. GLP-1 secretion and variables of carbohydrate metabolism were improved. Correlations were seen between GLP-1 changes and variations within microbial community abundances, specifically , the genus, and family. A conventional treatment to eradicate could improve carbohydrate metabolism possibly in relation with an increase in GLP-1 secretion. GLP-1 secretion may be related to alterations in intestinal microbiota, specifically and .

Objective: This study aimed to investigate the impact of electroacupuncture (EA) on blood glucose levels, gut microbiota, short-chain fatty acids (SCFAs), and glucagon-like peptide-1 (GLP-1) in a rat model of type 2 diabetes mellitus (T2DM).
Methods: Forty Sprague-Dawley (SD) rats were randomly assigned to five groups (n = 8/group) using a random number table: normal control, T2DM model, electroacupuncture (EA), EA + antibiotics (EA + A), and antibiotics (A). The normal rats received a standard diet and saline gavage, while the other groups were fed a high-fat diet and emulsion.

Background: Glucagon-like peptide-1 (GLP-1) is a crucial incretin hormone secreted by intestinal endocrine L cells. Given its pivotal physiological role, researchers have developed GLP-1 receptor agonists (GLP-1 RAs) through structural modifications. These analogues display pharmacological effects similar to those of GLP-1 but with augmented stability and are regarded as an effective means of regulating blood glucose levels in clinical practice.

This randomized trial tested the effect of metformin on glycemic control and cardiac function in patients with heart failure (HF) and type 2 diabetes while evaluating intestinal effects on selected gut microbiome products reflected by trimethylamine-N-oxide (TMAO) and gut-derived incretins. Metformin treatment improved glycemic control and postprandial metabolism and enhanced postprandial glucagon-like peptide 1 (GLP-1) secretion but did not influence cardiac function or the TMAO levels. Metabolic effects of metformin in HF may be mediated by an improvement in intestinal endocrine function and enhanced secretion of the gut-derived incretin GLP-1.

Aim: To describe the effects of Glucagon-like peptide-1 receptor agonists (GLP-1RA) in patients with familial partial lipodystrophy (FPLD) assessed in a real-life setting in a national reference network.
Patients And Methods: We retrospectively collected clinical and metabolic parameters in patients with FPLD in the French lipodystrophy reference network, who initiated GLP-1RA. Data were recorded before, at one-year (12 ± 6 months) and at the latest follow-up on GLP-1RA therapy (≥18 months).
