Effect of drugs on renal development

Area of Science:

• Pharmacology
• Developmental Biology
• Nephrology

Background:

• Drug-induced nephrotoxicity is well-documented, but effects on kidney development are less understood.
• Nephrogenesis, the formation of kidneys, concludes around 36 weeks gestation.
• Medications given during this critical period to pregnant women or preterm infants may disrupt normal kidney development.

Purpose of the Study:

• To review existing research on the impact of drug exposure during active nephrogenesis.
• To highlight the potential for drug-induced renal malformations and long-term sequelae.
• To emphasize the need for further investigation into drug effects on developing kidneys.

Main Methods:

• Literature review focusing on studies examining drug administration during pregnancy and in preterm neonates.
• Analysis of research concerning the effects of medications on renal development and potential long-term outcomes.
• Synthesis of current knowledge on drug-induced congenital anomalies of the kidney and urinary tract (CAKUT).

Main Results:

• Drug exposure during active nephrogenesis can lead to a spectrum of CAKUT, from renal agenesis to reduced nephron number.
• CAKUT is a leading cause of childhood renal replacement therapy.
• The effects of many common drugs on renal development remain largely uncharacterized.

Conclusions:

• Drug administration during critical periods of kidney development (pregnancy, preterm infancy) poses a risk for congenital anomalies of the kidney and urinary tract (CAKUT).
• These developmental abnormalities can have significant long-term health consequences.
• More research is urgently needed to assess the impact of various drugs on renal development and to inform clinical practice.
