Tenofovir seldom causes patients to complain of location effects, and some studies have suggested that it is unbosom of major toxicity. However, its use has been associated with the learning of intense, sometimes irreversible, nephritic dysfunction, and risks for this tortuousness are not head understood. Researchers account on 5 new cases of tenofovir-associated renal failure and reviewed 22 cases previously reported in the literature. All 27 patients were receiving tenofovir in a c onspiracy antiretroviral regimen that included ritonavir (21 patients), ddI (9 patients), and atazanavir (5 patients). Duration of tenofovir use ranged from 1 to 29 months (mean, 11 months). CD4-cell counts and viral loads ranged widely. All patients had ruler serum creatinine levels at baseline.

Renal failure was accompanied by Fanconi syndrome in 16 patients, proteinuria in 6, and urinary bank deposit characteristic of acute tubular necrosis in 8. deuce patients briefly unavoidable dialysis. After tenofovir was discontinued, urinary abnormalities resolved in all patients, although atomic number 23 still had so me degree of renal dysfunction after a mean ! follow-up of 7.5 months. The authors mull that interactions with other antiretrovirals are responsible for sporadic cases of tenofovirassociated renal failure. ritonavir inhibits secretion of tenofovir into the water and may raise serum tenofovir levels considerably. ddI may compete with tenofovir for urinary secretion, resulting in elevated serum levels of ddI and ddI-associated renal damage.
