Review Meta Analysis Comparative StudyGlucagon-like peptide-1 receptor agonists versus insulin in inadequately controlled patients with type 2 diabetes mellitus: a meta-analysis of clinical trials.
To compare the effect and safety of glucagon-like peptide-1 receptor agonists (GLP-1 RA) with insulin therapy on type 2 diabetes mellitus (T2DM) patients inadequately controlled with metformin and/or sulfonylurea. A systematic literature search on MEDLINE, Embase and Cochrane for randomized controlled trials (RCTs) was conducted using specific search terms 'GLP-1 insulin type 2 diabetes clinical trials' and eight eligible studies were retrieved. Data on mean change in haemoglobin A1c (HbA1C), weight loss, fasting plasma glucose (FPG), incidence of hypoglycaemia and gastrointestinal adverse events were extracted from each study and pooled in meta-analysis. ⋯ A significantly higher number of gastrointestinal adverse events were reported with GLP-1 group [M-H OR 15.00 (5.44,41.35) p < 0.01]. GLP-1 RA are promising new agents compared with insulin. Further prospective clinical trials are expected to fully evaluate the long-term effectiveness and safety of these therapies within the T2DM treatment paradigm.
