Insulin therapy Archives - Revista Brasileira de Ginecologia e Obstetrícia

Abstract

Objective:

The aim of this study is to assess the use of metformin with or without insulin for the treatment of Gestational Diabetes Mellitus compared to insulin alone.

Data sources:

This article consists of a systematic review of randomized clinical trials. The searches were carried out on MEDLINE including 7 studies, between 2010 to 2021.

Study selection:

Randomized clinical trials comparing metformin and insulin written in English, Spanish or Portuguese, with no time limit, were included.

Data collection:

Data was extracted from all the 7 articles and compared statistically when possible. Whenever data was not available or couldn't be statistically compared, the main results were described in detail.

Data synthesis:

Insulin alone is not superior than metformin with or without insulin on gestational diabetes mellitus.

Conclusion:

There is a potential viability of using metformin as an alternative compared to insulin alone in the treatment of Gestational Diabetes Mellitus. However, all assessed outcomes have a very low level of certainty of evidence and more studies are necessary to support these findings.
