Tenofovir disoproxil fumarate (TDF) is a recommended first-line therapy for both naïve and experienced patients with chronic hepatitis B (CHB), although reduced estimated glomerular filtration rate (eGFR), hypophosphatemia, hyperphosphaturia and Fanconi syndrome have been reported in some patients. Entecavir (ETV) could be considered as a rescue therapy for TDF-treated patients developing renal dysfunction, though patients with prior history of treatment with lamivudine (LAM) can develop ETV resistance strains, which can lead to potentially severe hepatitis flares...

Millions of people worldwide take tenofovir disoproxil fumarate (TDF) for the treatment of human immunodeficiency virus (HIV) and/or hepatitis B infection. Although generally safe and well tolerated, clinicians need to be aware that TDF can cause proximal renal tubular dysfunction and loss of bone mineral density, especially in patients with concomitant renal disease or other risk factors. We present the case of a patient with chronic HIV infection and urethral stricture who developed TDF-related proximal renal tubular dysfunction with hypophosphatemia and osteomalacia, presenting with bone pains, skeletal deformity, and disability...

Despite the therapeutic success of tenofovir (TFV) for treatment of HIV-1 infection, numerous cases of nephrotoxicity have been reported. Mitochondrial toxicity has been purported as the major target of TFV-associated renal tubulopathy but the underlying molecular mechanism remains unclear. In this report, we use metabolomics and proteomics with HK-2 cells and animal models to dissect the molecular pathways underlying nephropathy caused by TFV and its more toxic analog, adefovir (ADV). Proteomic analysis shows that mitochondrial chaperone TRAP1 and mtDNA replicating protein SSBP1 were significantly down-regulated in TFV and ADV treated HK-2 cells compared with controls...

Tenofovir (TFV) is an antiviral drug approved for treating Human Immunodeficiency Virus (HIV) and Hepatitis B. TFV is administered orally as the prodrug tenofovir disoproxil fumarate (TDF) which then is deesterified to the active drug TFV. TFV induces nephrotoxicity characterized by renal failure and Fanconi Syndrome. The mechanism of this toxicity remains unknown due to limited experimental models. This study investigated the cellular mechanism of cytotoxicity using a human renal proximal tubular epithelial cell line (HK-2)...

The human immunodeficiency virus (HIV)/hepatitis B virus (HBV) co-infection is likely to be associated with an increased risk of kidney disease, due to the additional factors that may affect renal function in the HIV population. We aimed to evaluate renal toxicity in HIV/HBV and HBV mono-infected patients on long-term therapy with tenofovir (TDF) and to explore the association of polymorphisms in ATP-binding cassette (ABCC)2, ABCC4, ABCC10 with the development of renal dysfunction. From September 2006 to November 2014, 44 HIV/HBV co-infected and 34 HBV mono-infected patients were commenced on TDF...

OBJECTIVE: In nephrotoxicity induced by tenofovir disoproxil fumarate (TDF), tubular dysfunction precedes the decline in GFR, suggesting that tubular markers are more sensitive than estimated glomerular filtration rate (eGFR). The hypothesis that urinary β2 microglobulin (β2 M), a tubular function marker, can predict TDF-renal dysfunction in HIV-1-infected patients was tested. DESIGN: A single-center observational study. METHODS: The inclusion criteria were: HIV-1-infected patients who started TDF-containing antiretroviral therapy from 2004 to 2013, urinary β2 M after and closest to the day of TDF initiation within 180 days (termed 'β2 M after TDF') was measured...

 Tenofovir disoproxil fumarate (TDF) is a nucleotide reverse transcriptase inhibitor indicated for treatment of patients with chronic hepatitis B virus (CHB) and human immunodeficiency virus (HIV) infections. Despite the good safety profile of the drug, Fanconi syndrome is a possible adverse reaction of TDF treatment, especially in HIV-infected patients. Only a few cases have been reported in patients with CHB-monoinfections. This report presents a case of a 58-year-old man with mild HBeAg-negative CHB who was exposed to TDF and developed drug-induced Fanconi syndrome...

BACKGROUND: In Thailand, the combined generic anti-retroviral drug stavudine/lamivudine/nevirapine (d4T/3TC/NVP) has been used to treat human immunodeficiency virus (HIV)-infected individuals since 2001. Due to relatively frequent adverse effects, d4T gradually has been replaced with tenofovir disoproxil fumarate (TDF). Although the frequency of adverse drug effects with TDF is lower than that with d4T, TDF is known to induce kidney dysfunction, especially in the proximal tubules. It has been reported that renal tubular transporters, including members of the multi-drug resistant (MDR) protein family, are implicated in tenofovir extrusion and may, therefore, confer susceptibility to TDF-induced kidney tubular dysfunction (KTD)...

BACKGROUND: Tenofovir disoproxil fumarate (TDF) may cause acute kidney injury and proximal tubular dysfunction. However, no detailed studies document urinary phosphate wasting as a marker of TDF-induced tubulopathy. METHODS: Records of HIV-infected patients with presumed TDF toxicity were reviewed. We describe the characteristics and clinical course of 15 patients who had documented elevated (>20%) fractional excretion of phosphate (FEphos). RESULTS: Patients were predominantly Caucasian and male (73 and 80%, respectively), with a mean age of 56 years (range 38-76)...

BACKGROUND: The use of tenofovir has been rapidly increasing in Vietnam. Several studies identified low body weight as a risk factor for tenofovir-induced nephrotoxicity. However, little is known about the impact of tenofovir on renal function in HIV-infected Vietnamese with generally low weight. METHODS: An observational single-center cohort of adult HIV-infected patients on antiretroviral therapy at National Hospital of Tropical Diseases, Hanoi. Patients on tenofovir or with creatinine clearance ≤60 ml/min at baseline were excluded...

The long-term use of tenofovir, a commonly used anti-HIV drug, can result in renal damage. The mechanism of tenofovir disoproxil fumarate (TDF) nephrotoxicity is not clear, although it has been shown to target proximal tubular mitochondria. In the present study, the effects of chronic TDF treatment on the proximal tubular function, renal mitochondrial function, and the activities of the electron transport chain (ETC) complexes were studied in rats. Damage to proximal tubular mitochondria and proximal tubular dysfunction was observed...

REVIEW
A M Hall, P Bass, R J Unwin
A number of therapeutic drugs are toxic to the kidney proximal tubule (PT) and can cause the renal Fanconi syndrome (FS). The most frequently implicated drugs are cisplatin, ifosfamide, tenofovir, sodium valproate and aminoglycoside antibiotics, and the new oral iron chelator deferasirox has also recently been associated with FS. The incidence of full or partial FS is almost certainly under-estimated due to a lack of appropriate systematic studies, variations in definitions of tubular dysfunction and under-reporting of adverse events...

Tenofovir disoproxyl fumarate is a known cause of kidney tubular dysfunction in HIV-infected patients. Recent studies reported significant association between specific allelic variants in ABCC2, ABCC4 and/or ABCC10 genes and the development of kidney tubular dysfunction in HIV-infected adults. We describe the first 2 cases of vertically HIV-infected patients affected by kidney tubular dysfunction associated with polymorphisms in the ABCC genes.

BACKGROUND: Nephrotoxicity is a dose limiting side effect of tenofovir, a reverse transcriptase inhibitor that is used for the treatment of HIV infection. The mechanism of tenofovir nephrotoxicity is not clear. Tenofovir is specifically toxic to the proximal convoluted tubules and proximal tubular mitochondria are the targets of tenofovir cytotoxicity. Damaged mitochondria are major sources of reactive oxygen species and cellular damage is reported to occur after the antioxidants are depleted...

We describe a case of 68-year-old Japanese man with HIV-1 infection who developed acute kidney injury with prominent tubular dysfunction immediately after starting tenofovir-containing antiretroviral therapy. Antiretroviral therapy was discontinued in two weeks but renal function, as well as tubular function, did not shown full recovery even at a 3-year follow-up examination. Acute tubular necrosis, a rare but well-known side effect of tenofovir, was suspected, but kidney biopsy confirmed interstitial nephritis...
