Chronic complications in diabetes mellitus

Area of Science:

• Endocrinology
• Cardiovascular Medicine
• Nephrology

Background:

• Diabetes mellitus is a prevalent disease in Japan, characterized by persistent hyperglycemia.
• Hyperglycemia leads to microvascular and macrovascular damage, affecting eyes, kidneys, nerves, and large vessels, causing conditions like myocardial infarction and gangrene.
• Diabetic vascular complications are linked to metabolic abnormalities, with the diacyl glycerol-protein kinase C pathway implicated.

Purpose of the Study:

• To explore the role of metabolic abnormalities, particularly the diacyl glycerol-protein kinase C pathway, in diabetic vascular complications.
• To review the efficacy of glycemic and blood pressure control in managing diabetic complications.
• To highlight the potential role of nutritional considerations in improving management strategies.

Main Methods:

• Review of existing literature on diabetic vascular complications and their pathogenesis.
• Examination of studies on the diacyl glycerol-protein kinase C pathway and protein kinase C inhibitors in diabetic animal models.
• Analysis of results from large-scale clinical trials on glycemic and blood pressure control.

Main Results:

• The diacyl glycerol-protein kinase C pathway is proposed as a key player in both microvascular and macrovascular complications.
• Protein kinase C inhibitors have shown beneficial effects on lesions in diabetic animal models.
• Large-scale clinical trials confirm the effectiveness of glycemic and blood pressure control in managing diabetic complications.

Conclusions:

• Near-normal glycemic and blood pressure control are essential for preventing and managing diabetic complications.
• Nutritional strategies may enhance the effectiveness of current management approaches for diabetes.
• Further research into metabolic pathways and nutritional interventions is warranted for comprehensive diabetes care.
