Glucagon-like peptide-1 receptor-agonists treatment for cardio-metabolic parameters in schizophrenia patients: a systematic review and meta-analysis

Abstract

AimsWe performed this meta-analysis to evaluate the efficacy and safety of glucagon-like peptide-1 receptor-agonists (GLP-1RA) treatment on cardio-metabolic parameters among antipsychotic-treated patients with schizophrenia.MethodsWe searched the Web of Science, Cochrane Central Register of Controlled Trials, PubMed, PsycINFO, and Scopus for relevant Randomized Clinical trials (RCTs) from inception until 1 August 2022. Documents were screened for qualified articles, and all concerned outcomes were pooled as risk ratios (RR) or mean difference (MD) in the meta-analysis models using Review Manager (RevMan version 5.4).ResultsPooling data from 7 RCTs (398 patients) showed that GLP-1 RA was superior to placebo with regard to body weight [MD = - 4.68, 95% CI (-4.90,−4.46), P < 0.00001], waist circumference [MD = - 3.66, 95% CI (-3.89,−3.44), P < 0.00001], body mass index (BMI) [MD = - 1.09, 95% CI (-1.25,−0.93), P < 0.00001], systolic blood pressure (SBP) [MD = - 3.07, 95% CI (-3.61,−2.53), P < 0.00001], and diastolic blood pressure (DBP) [MD = - 2.02, 95% CI (-2.42,−1.62), P < 0.00001]. The total effect did not favor either of the two groups with respect to insulin and respiratory adverse events {[MD = - 0.06, 95% CI (-0.36, 0.24), p = 0.70], [RR = 0.66, 95% CI (0.31, 1.40), p = 0.28]; respectively}.ConclusionOur analysis revealed that GLP-1 RA treatment is safe and effective on cardio-metabolic parameters over control in antipsychotic-treated patients with schizophrenia. Nevertheless, the present evidence is not sufficient to confirm the safety and efficacy of GLP-1RA treatment on insulin and respiratory adverse events. Therefore, further studies are recommended.Systematic review registrationhttp://www.crd.york.ac.uk/PROSPERO/, identifier: CRD42022333040.

Schizophrenia - Time to Commit to Policy Change

“…A previous systematic review demonstrated that use of such agents reduced weight gain and improved key metabolism markers. 259 However, barriers exist with respect to monitoring and managing cardiometabolic risk factors in patients prescribed antipsychotic medication, and there is a need for clear guidelines and educational resources to try and address these. 260 Smoking is another major cause of ill health in people with schizophrenia.…”
