Tenofovir (TFV) can affect kidney function, primarily the proximal tubule. While severe toxicity is rare, milder effects and long-term impacts on kidney and bone health require further investigation.
Area of Science:
- Nephrology
- Pharmacology
- Virology
Background:
- Tenofovir (TFV) is a crucial antiretroviral medication for HIV treatment.
- TFV exposure is linked to declines in estimated glomerular filtration rate (eGFR).
- TFV primarily targets proximal tubule (PT) cells, potentially causing Fanconi syndrome or acute kidney injury.
Purpose of the Study:
- To review the effects of TFV on renal function.
- To explore the mechanisms and risk factors of TFV-induced nephrotoxicity.
- To discuss TFV use in new populations and potential mitigation strategies.
Main Methods:
- Literature review of studies on TFV nephrotoxicity.
- Analysis of mechanisms targeting PT mitochondria.
- Examination of risk factors and clinical outcomes.
Main Results:
- TFV toxicity affects the PT, with milder dysfunction being more common than severe injury.
- Changes in eGFR may be due to inhibited creatinine secretion, not solely glomerular changes.
- Risk factors include pre-existing kidney disease, older age, and low body mass.
Conclusions:
- Long-term significance of mild PT dysfunction on kidney and bone health is uncertain.
- TFV use is expanding, necessitating understanding of risks in diverse populations.
- Strategies for preventing TFV toxicity and enhancing recovery are being developed.

Renal Failure: Dose Adjustments
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
However, dosage adjustments...
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 out...
