Methods: A double-blind, randomized, placebo-controlled in parallel groups clinical trial was performed in 36 pharmacological treatment-na\u00efve patients with T2DM. They received propolis (300 mg), metformin (850 mg), or placebo twice daily before breakfast and dinner for 12 weeks. At the beginning and end of the study, fasting plasma glucose (FPG), 2-h postload glucose (2-h PG) during a 75-g oral glucose tolerance test, glycated hemoglobin A1c (A1C) and a metabolic profile were measured. Areas under the curve (AUC) of glucose and insulin, total insulin secretion (insulinogenic index), the first phase of insulin secretion (Stumvoll index), and insulin sensitivity (Matsuda index) were calculated. Statistical analyses: Kruskal-Wallis, Mann-Whitney U and Wilcoxon tests. Results: The propolis and metformin groups exhibited significant reductions in FPG (p=0.009 and p=0.001, respectively), 2-h PG (p=0.034 and p=0.001, respectively) levels, AUC of insulin, Stumvoll index, and an increment in the Matsuda index. The comparison of the changes from baseline to the end showed significant differences between placebo and propolis in FPG (p=0.004) and A1C (p=0.049) levels, while between placebo and metformin were in FPG (p=0.002), 2-h PG (p=0.004) and A1C (p=0.007) levels. Conclusions: The administration of propolis and metformin compared to placebo reduced FPG and A1C levels; in addition, metformin decreased 2-h PG, AUC of glucose and insulin, high-density lipoprotein cholesterol, and increased the insulin sensitivity. <\/jats:p>","DOI":"10.1024\/0300-9831\/a000760","type":"journal-article","created":{"date-parts":[[2022,8,15]],"date-time":"2022-08-15T06:12:17Z","timestamp":1660543937000},"page":"498-506","source":"Crossref","is-referenced-by-count":21,"title":["Anti-hyperglycemic effects of propolis or metformin in type 2 diabetes mellitus"],"prefix":"10.31083","volume":"93","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8915-342X","authenticated-orcid":true,"given":"Paola D.","family":"Ochoa-Morales","sequence":"first","affiliation":[{"name":"Instituto de Terap\u00e9utica Experimental y Cl\u00ednica, Centro Universitario de Ciencias de la Salud, Universidad de Guadalajara, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6070-0859","authenticated-orcid":true,"given":"Manuel","family":"Gonz\u00e1lez-Ortiz","sequence":"additional","affiliation":[{"name":"Instituto de Terap\u00e9utica Experimental y Cl\u00ednica, Centro Universitario de Ciencias de la Salud, Universidad de Guadalajara, Mexico"},{"name":"Centro de Investigaci\u00f3n Biom\u00e9dica para la Salud, SA de CV, Guadalajara, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3339-2808","authenticated-orcid":true,"given":"Esperanza","family":"Mart\u00ednez-Abundis","sequence":"additional","affiliation":[{"name":"Instituto de Terap\u00e9utica Experimental y Cl\u00ednica, Centro Universitario de Ciencias de la Salud, Universidad de Guadalajara, Mexico"},{"name":"Centro de Investigaci\u00f3n Biom\u00e9dica para la Salud, SA de CV, Guadalajara, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1767-1719","authenticated-orcid":true,"given":"Karina G.","family":"P\u00e9rez-Rubio","sequence":"additional","affiliation":[{"name":"Instituto de Terap\u00e9utica Experimental y Cl\u00ednica, Centro Universitario de Ciencias de la Salud, Universidad de Guadalajara, Mexico"},{"name":"Centro de Investigaci\u00f3n Biom\u00e9dica para la Salud, SA de CV, Guadalajara, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2754-2542","authenticated-orcid":true,"given":"Anayeli D.
