Abstract

Aim: To evaluate the evidence pertaining to the efficacy of the supplementation of probiotics on the blood glucose level of pregnant women with gestational diabetes mellitus (GDM). Background: Women with the GDM are subsequently at risk to develop type 2 diabetes mellitus, within three to six years after delivery. This makes it crucial for all pregnant women with the GDM, to monitor their blood glucose levels regularly to minimize the adverse pregnancy outcomes. The earlier studies revealed that the probiotics could improve glycaemic control and mitigate the adverse effects of type 2 diabetes mellitus. Design: A systematic review and meta-analysis. Data sources: The Google Scholar, Pubmed/Medline, Cochrane library, ProQuest, Ovid, and EMBASE were systematically searched for the available clinical trials. Review methods: Randomized clinical trials (RCTs) for evaluating the effects of the probiotics on the pregnancy outcomes such as glycaemic control as primary outcome were included to achieve the aim of this review and meta-analysis. Two reviewers from the team extracted the data and assessed the risk of bias in the eligible studies independently. The meta-analysis was performed by applying a model of fixed effects using the Revman 5.3 software. Results: Nine clinical trials involving 1053 participants were included in the meta-analysis. Though the components of probiotics varied significantly, Lactobacillus species was given to all the participants in all the trials included in this review. The results showed that the probiotics asignificantly improved the glycaemic control biomarkers (Fasting blood glucose and insulin sensitivity level) (P < 0.005). Conclusion: Probiotic-supplements seemed to improve the glycaemic control biomarkers. Thus, this review highlights the considerable evidence that the supplementation of probiotics has the beneficial effects on the glycaemic control markers and may be useful as a supplementary therapy among the women with the GDM. This finding would foster the health care professionals and the nurses to create awareness on the potential benefits of the supplementation of the probiotics among the women with the GDM and elevated glycaemic control biomarkers.
