To evaluate preclinical and clinical evidence regarding the impact of diabetes on sepsis pathophysiology, host susceptibility, and infection outcomes.
Reviewed experimental animal investigations using streptozotocin-induced diabetic mouse models.
Assessed bacterial clearance, pathogen sequestration, mortality curves, and cytokine expression across various bacterial challenges including group B Streptococcus, Pseudomonas aeruginosa, and tuberculosis.
Diabetic mice demonstrated defective bacterial clearance, prolonged bacteremia, and delayed mortality (>72 hours) linked to persistent microorganism sequestration in the liver and spleen.
Impaired anti-bacterial defenses were characterized by decreased antigen-responsive T-cells and lower levels of protective cytokines, specifically interferon-gamma and interleukin-12.
Blood glucose regulation via insulin therapy successfully reversed host defense defects and restored T helper type 1 immune pathways.

Implication

Review reveals impaired bacterial clearance and increased mortality during sepsis in diabetic models, suggesting glycemic control restores host immune defense.
