A randomized, placebo-controlled study evaluated the effects multiple-doses (28 days) dipeptidyl peptidase-IV (DPP-IV) inhibitor PF-734200 on DPP-IV activity, glucose, glucagon-like peptide-1 (GLP-1), glucagon and insulin levels in 72 subjects with type 2 diabetes. The relationship between changes in active GLP-1 and glucose during a meal test appeared non-linear.

Diabetes mellitus (DM) is a metabolic disease marked by an excessive rise in blood sugar (glucose) levels caused by a partial or total absence of insulin production, combined with alterations in the metabolism of proteins, lipids, and carbohydrates. The International Diabetes Federation estimates that 425 million individuals globally had diabetes in 2017 which will be 629 million by 2045. Several medications are used to treat DM, but they have limitations and side effects including weight gain, nausea, vomiting, and damage to blood vessels and kidneys.

The use of fish rest raw material for the production of fish protein hydrolysates (FPH) through enzymatic hydrolysis has received significant interest in recent decades. Peptides derived from fish proteins are known for their enhanced bioactivity which is mainly influenced by their molecular weight. Studies have shown that novel technologies, such as high-pressure processing (HPP), can effectively modify protein structures leading to increased biological activity.

Aims: To compare the efficacy of adding imeglimin versus that of metformin dose escalation on glycemic control in subjects with type 2 diabetes treated with a dipeptidyl peptidase-4 inhibitor plus low-dose metformin (500-1000 mg/day).

Materials And Methods: In this multicentre, open-labelled, prospective, randomized, parallel-group comparison study, the addition of imeglimin (2000 mg/day) or metformin escalation was applied for 24 weeks in eligible subjects. The primary endpoint was the mean change in glycated haemoglobin (HbA1c) over 24 weeks.

Aim: To comprehensively evaluate the benefits and risks of glucagon-like peptide-1 receptor agonists (GLP-1RA), dipeptidyl peptidase 4 inhibitors (DPP4i), and sodium-glucose cotransporter 2 inhibitors (SGLT2i).

Materials And Methods: A systematic search of PubMed, EMBASE, and Cochrane Central Register of Controlled Trials (CENTRAL) from inception to November 2023 to identify randomized cardiovascular and kidney outcome trials that enrolled adults with type 2 diabetes, heart failure, or chronic kidney disease and compared DPP4i, GLP-1RAs, or SGLT2i to placebo. Twenty-one outcomes (e.
