Kidney tubular abnormalities in the absence of impaired glomerular function in HIV patients treated with tenofovir

Abstract: Exposure to TDF is associated with an increased risk over time of kidney tubular abnormalities in the absence of significant impaired glomerular function. Although long-term consequences of this tubulopathy are unknown, close monitoring of accelerated bone mineral loss and renal insufficiency are warranted. Periodic screening of tubular function parameters should be recommended to patients receiving TDF.

“…Therefore, a decrease in CL may occur with renally eliminated drugs, such as TFV and FTC. Although severe toxicity is rare, subclinical decline in proximal tubule function may be present in up to 20% of patients receiving TFV 7. Older age is a known risk factor for increased TFV renal toxicity, and electrolyte changes due to renal damage may play a role in bone toxicity as well 8.…”

“…Já foi demonstrado, inclusive, que o TDF é substrato de um dos transportadores basolaterais de ânions orgânicos. Nesse caso, o principal ânion orgâni-co envolvido na absorção de TDF pelas células tubulares a partir da corrente sanguínea é o OAT1 [2][3][4] . Do interior da célula tubular para a luz do túbulo, acredita-se que o TDF seja transportado pelas proteínas multidroga-resistentes tipos 1 e 4 (MPR1 e MPR4) [2][3][4] .…”

“…O que pode determinar a nefrotoxicidade do TDF é o seu acú-mulo no interior das células tubulares consequente a um desbalanço entre sua entrada na célula, mediada pelos ânions orgâni-cos, principalmente o OAT1, e sua excreção para a luz tubular, mediada pelas MPR1 e MPR4 2,3 .…”
