Abstract:
This review summarizes our current understanding of the role of cyclo-oxygenase inhibitors (COXI) in influencing the structural development as well as the function of the developing kidney. COXI administered either during pregnancy or after birth can influence kidney development including nephronogenesis, and can decrease renal perfusion and ultrafiltration potentially leading to acute kidney injury in the newborn period. To date, which COX isoform (COX-1 or COX-2) plays a more important role in during fetal development and influences kidney function early in life is not known, though evidence points to a predominant role for COX-2. Clinical implications of the use of COXI in pregnancy and in the newborn infant are also evaluated herein, with specific reference to the potential effects of COXI on nephronogenesis as well as newborn kidney function.
Insights
Cyclo-oxygenase inhibitors (COXI) can impact fetal kidney development and function, potentially causing acute kidney injury in newborns. Further research is needed to clarify the roles of COX-1 and COX-2 in these processes.
Area of Science:
- Nephrology
- Developmental Biology
- Pharmacology
Background:
- Cyclo-oxygenase inhibitors (COXI) are commonly used medications.
- Their effects on the developing kidney are not fully understood.
- Kidney development is a complex process crucial for lifelong health.
Purpose of the Study:
- To review the current understanding of COXI's role in kidney development.
- To evaluate the impact of COXI on nephronogenesis and renal function.
- To assess clinical implications for pregnant women and newborns.
Main Methods:
- Literature review of studies on COXI and kidney development.
- Analysis of data on COXI administration during pregnancy and postpartum.
- Evaluation of effects on renal perfusion and ultrafiltration.
Main Results:
- COXI can negatively affect kidney development, including nephronogenesis.
- Administration of COXI can decrease renal perfusion and ultrafiltration.
- Potential for acute kidney injury in newborns exposed to COXI.
- Evidence suggests a predominant role for COX-2 in fetal kidney development.
Conclusions:
- COXI use during pregnancy or after birth can adversely impact kidney development and function.
- Further investigation is required to elucidate the specific roles of COX-1 and COX-2.
- Clinical caution is advised when using COXI in pregnant women and neonates.

Renal Drug Excretion: Overview
A nephron consists of two primary structures: the renal corpuscle and the renal tubule. The renal corpuscle contains the glomerulus, a network of capillaries where the first step of renal excretion, glomerular filtration, occurs. Blood pressure forces water, ions, and small molecules...
