Sex Differences in Diabetic Kidney Disease.

Area of Science:

• Nephrology
• Endocrinology
• Diabetology

Background:

• Diabetes mellitus affects men and women similarly in prevalence, but its complications, like diabetic kidney disease (DKD), show sex-specific patterns.
• Women with diabetes exhibit higher mortality and increased prevalence of DKD risk factors (hypertension, hyperglycemia, obesity, dyslipidemia).
• Existing evidence on sex's impact on DKD prevalence and progression is limited and inconsistent, with unclear reasons for diminished female protection in diabetes.

Purpose of the Study:

• To explore the complex relationship between sex and the risk and progression of diabetic kidney disease.
• To investigate the potential role of sex hormones, such as estrogens, in the pathophysiology of DKD.
• To highlight the need for a better understanding of sex differences for personalized DKD treatment strategies.

Main Methods:

• Review and synthesis of existing literature on sex differences in diabetic kidney disease.
• Analysis of factors contributing to sex-specific DKD risk, including age at onset, diabetes type, and duration.
• Exploration of the influence of sex hormones on renal function in the context of diabetes.

Main Results:

• The protective effect of the female sex against kidney disease is reduced in diabetic individuals.
• Inconsistencies exist regarding whether men or women face a higher risk of DKD.
• Factors like age, diabetes type, and duration are associated with observed sex differences in DKD risk.

Conclusions:

• Sex differences in diabetic kidney disease are evident but not fully understood, necessitating further research.
• Sex hormones, particularly estrogens, are implicated in renal function regulation and DKD pathophysiology.
• A deeper comprehension of sex-specific DKD mechanisms is essential for developing personalized and sex-tailored therapeutic approaches.
