Circulating amino acids and cardiometabolic risk profile in offspring of women with type 1 diabetes: cross-sectional...

Area of Science:

• Endocrinology and Metabolism
• Cardiovascular Science
• Nutritional Biochemistry

Background:

• Branched-chain amino acids (BCAAs) are linked to cardiovascular disease (CVD) risk in adults.
• Offspring of women with type 1 diabetes may have an altered cardiometabolic risk profile.
• Investigating early-life metabolic markers is crucial for understanding long-term health outcomes.

Purpose of the Study:

• To determine if young adult offspring of women with type 1 diabetes exhibit an altered amino acid profile associated with cardiometabolic risk.
• To assess cardiovascular disease and cardiometabolic risk factors in this specific population.
• To explore the relationship between specific amino acid levels and cardiometabolic health.

Main Methods:

• Cross-sectional case-control study involving 73 offspring of women with type 1 diabetes and 82 controls.
• Clinical assessments included laboratory tests and questionnaires at ages 18-23 years.
• Serum amino acid levels were analyzed using nuclear magnetic resonance (NMR) spectroscopy after a 10-hour fast.

Main Results:

• No significant differences in cardiovascular disease or cardiometabolic risk factors were found between cases and controls.
• Circulating amino acid levels were comparable between the two groups.
• A higher glucogenic score (alanine, glycine) was observed in overweight male offspring of women with type 1 diabetes (adjusted p=0.015).

Conclusions:

• The study does not support the hypothesis that serum amino acid profiles in early adulthood are associated with adverse cardiometabolic risk in offspring of women with type 1 diabetes.
• Findings suggest that other factors may be more influential in determining cardiometabolic risk in this population.
• Further research is warranted to elucidate the role of amino acids in cardiovascular disease development in this high-risk group.
