Organotin Compounds Toxicity: Focus on Kidney.

Area of Science:

• Environmental toxicology
• Renal medicine
• Organometallic chemistry

Background:

• Organotin compounds (OTs) are widely used synthetic chemicals with known endocrine-disrupting effects.
• While OTs impact various organs, their effects on kidney function are less understood.
• Kidneys are vulnerable to xenobiotics due to their role in metabolism and pollutant accumulation.

Purpose of the Study:

• To review existing research on the renal effects of organotin exposure.
• To consolidate knowledge on OTs' impact on kidney structure and function.
• To highlight the need for further investigation into OTs' nephrotoxicity.

Main Methods:

• Literature review of experimental and epidemiological studies.
• Analysis of mechanisms underlying OTs' renal toxicity.
• Synthesis of data on OTs' effects on renal cells and overall kidney function.

Main Results:

• Chronic OTs exposure is associated with a threefold increase in kidney stone prevalence.
• OTs inhibit renal H+/K+-ATPase, causing hypokalemia, tubular acidosis, and increased urinary pH.
• OTs induce nephrotoxicity via increased reactive oxygen species (ROS), leading to oxidative stress and cell damage.

Conclusions:

• Organotin compounds pose significant risks to kidney health, contributing to nephrolithiasis and cellular damage.
• The mechanisms involve direct inhibition of renal transporters and induction of oxidative stress.
• Further research is crucial to fully elucidate the extent of OTs' impact on renal function and structure.
