Developmental programming of hypertension and kidney disease

Area of Science:

• Developmental biology
• Nephrology
• Public health

Background:

• Developmental programming, or developmental origins of health and disease, links early life conditions to later health outcomes.
• Premature birth (<37 weeks gestation) and low birth weight (<2,500g) are associated with increased risk of late-onset diseases.
• Chronic kidney disease (CKD) and hypertension risk in these infants may stem from reduced nephron endowment.

Purpose of the Study:

• To discuss the impact of premature birth, low birth weight, intrauterine environment, and infant feeding on hypertension and renal disease development.
• To examine the kidney's role in the developmental programming of hypertension and CKD.

Main Methods:

• Literature review and synthesis of existing evidence.
• Analysis of factors influencing intrauterine development and nephron endowment.
• Discussion of the relationship between early life events and adult-onset disease.

Main Results:

• Reduced nephron endowment is a key factor in the susceptibility to CKD and hypertension in premature or LBW infants.
• Uteroplacental insufficiency, maternal diet, hyperglycemia, vitamin A deficiency, glucocorticoid disruption, and ethanol exposure can lead to low nephron number.
• The intrauterine environment and infant feeding significantly influence long-term renal and cardiovascular health.

Conclusions:

• Early life interventions targeting the intrauterine milieu and infant nutrition are crucial for preventing later-life hypertension and CKD.
• Understanding developmental programming is essential for improving long-term health outcomes in vulnerable infants.
• The kidney plays a central role in mediating the effects of early life exposures on adult health.
