Impact of Sucrose Consumption on the Metabolic, Immune, and Redox Profile of Mice with Gestational Diabetes Mellitus.

Carbohydrate consumption during pregnancy represents an important source of energy; its consumption, however, can cause gestational diabetes mellitus (GDM), body weight gain, inflammation, increased glucose transport to the fetus, adiposity, and a risk of macrosomia. The objective was to research the impact of sucrose consumption during pregnancy on the metabolic, immune, and redox profile in female mice with GDM. A total of 24 female CD1 mice were used, divided into two groups: Control and GDM. Each group was subdivided into two subgroups: (a) Without sucrose and (b) With sucrose. The females were mated, and, once pregnancy was confirmed, GDM was induced by administering 230 mg/kg of streptozotocin subcutaneously. GDM was confirmed by glucose ≥ 200 mg/dL and the presence of polyphagia, polydipsia, and change in body weight. Metabolic, immune, and redox profile parameters were determined. Sucrose consumption groups increase HOMA-IR and the secretion of insulin, adiponectin, and leptin; it also increased the secretion of proinflammatory cytokines and the production of IgA and IgG antibodies, decreased the activity of the Glutathione Reductase enzyme, and increased the production of TBARS and AGE. High sucrose consumption increases the inflammatory response mediated mainly by CD8
