Synbiotic Nutraceutical Mitigates Gestational Diabetes Effects and Cardiovascular Dysfunction in Rat Offspring

Area of Science:

• Microbiology
• Endocrinology
• Nutraceutical Science

Background:

• Gestational diabetes mellitus (GDM) poses risks to maternal and fetal health.
• Dysbiosis and inflammation are key factors in GDM pathogenesis.
• Offspring of mothers with GDM are at increased risk for long-term health issues, including autonomic dysfunction.

Purpose of the Study:

• To evaluate the efficacy of a nutraceutical containing jabuticaba peel and Limosilactobacillus fermentum in a rat model of GDM.
• To assess the nutraceutical's impact on gut microbiota, metabolic profiles, and inflammatory markers in dams with GDM.
• To determine the nutraceutical's protective effects on cardiac autonomic function in GDM offspring.

Main Methods:

• Pregnant Wistar rats were induced with GDM and treated with the nutraceutical (GDM+Nut) or vehicle.
• Gut microbiota composition, serum inflammatory cytokines (TNF-α, IL-6), glycaemic and lipid profiles were analyzed.
• Cardiac autonomic function was assessed in the offspring post-weaning.

Main Results:

• Nutraceutical administration improved glucose tolerance and reduced serum TNF-α and IL-6 levels in GDM rats.
• Gut microbiota beta diversity increased, with a higher abundance of short-chain fatty acid-producing bacteria.
• Maternal nutraceutical supplementation mitigated autonomic dysfunction in the offspring.

Conclusions:

• The jabuticaba peel and Limosilactobacillus fermentum nutraceutical demonstrates potential as an adjunct therapy for GDM.
• This nutraceutical may help restore gut microbiota balance and reduce systemic inflammation in GDM.
• Maternal supplementation offers protective benefits against GDM-induced autonomic dysfunction in offspring.
