A case of tenofovir-induced Fanconi syndrome in a patient receiving antiretroviral therapy for HIV infection, with resolution of the related electrolyte abnormalities upon switch from tenofovir disoproxil fumarate to tenofovir alafenamide fumarate, is reported. Tenofovir alafenamide fumarate, a novel prodrug of tenofovir containing significantly lower doses of tenofovir than tenofovir disoproxil fumarate, has been associated with a favourable renal profile compared to tenofovir disoproxil fumarate. Generally, the rare complication of tenofovir disoproxil fumarate-induced Fanconi syndrome is managed by cessation of tenofovir...

Denosumab, a novel agent that inhibits osteoclasts, reduces the risk of fracture in patients with osteoporosis. However, worsening of hypophosphatemia and other symptoms may be induced by denosumab in patients with pre-existing hypophosphatemic osteomalacia. A 58-year-old man with hepatitis B presented with diffuse bone pain and muscle weakness. Denosumab was prescribed by the orthopedist according to documented low bone mass and spine compression fracture. After administering denosumab, the patient's bone pain worsened, and he later developed a right tibia stress fracture...

Tenofovir disoproxil fumarate (TDF, commonly termed 'tenofovir') is the antiretroviral most commonly implicated in antiretroviral-induced nephrotoxicity. As patients on successful antiretroviral therapy (ART) age, their risk for developing renal disease may increase in part because of ART itself, but more importantly, because of HIV-associated and non-HIV-associated comorbidity. Therefore, clinicians need an approach to managing renal disease in people on TDF. TDF as a cause of acute kidney injury (AKI) or chronic kidney disease (CKD) is uncommon, and clinicians should actively exclude other causes (Box 1)...

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)...

Fanconi Anemia (FA) is a genetic disorder characterized by elevated cancer susceptibility and pro-inflammatory cytokine production. Using SLX4(FANCP) deficiency as a working model, we questioned the trigger for chronic inflammation in FA. We found that absence of SLX4 caused cytoplasmic DNA accumulation, including sequences deriving from active Long INterspersed Element-1 (LINE-1), triggering the cGAS-STING pathway to elicit interferon (IFN) expression. In agreement, absence of SLX4 leads to upregulated LINE-1 retrotransposition...

Tenofovir disoproxil fumarate (TDF) is a nucleotide reverse transcriptase inhibitor discovered in the USA in 2001. It is currently the treatment of choice for patients co-infected with human immunodeficiency virus (HIV) and hepatitis B virus. Its antiretroviral efficacy and good tolerance are responsible for the higher frequency of prescriptions compared with other nucleoside analogs. However, it can induce acute renal toxicity causing impairment of the proximal tubular function of the kidney. This is highly dependent on factors such as associated co-prescription didanosine or a protease inhibitor "boosted" with ritonavir, preexisting renal insufficiency, low body weight, or presence of associated diabetes...

 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...

Tenofovir induced fanconi syndrome (FS) presenting as hypokalemic paralysis is an extremely rare complication in patients on anti-retroviral therapy. We report a 50-year-old male with acquired immunodeficiency syndrome on tenofovir-based anti-retroviral therapy who presented with acute onset quadriparesis. On evaluation, he was found to have hypokalemia with hypophosphatemia, glucosuria and proteinuria suggesting FS. He regained normal power in limbs over next 12 h following correction of hypokalemia. Ours would be the second reported case in India...

BACKGROUND: Renal disease is an emerging problem in patients living with human immunodeficiency virus (HIV), as illustrated by an increased incidence of acute kidney injury and chronic kidney disease (CKD) from HIV, its associated treatment and comorbidities such as diabetes and vascular disease. We have established a combined HIV-renal clinic to manage such patients, enhance their treatment and minimize outpatient visits. METHODS: We have analysed the outcomes of the first 99 patients seen in the clinic using electronic patient records...

Tenofovir disoproxil fumarate (TDF) is a nucleotide reverse transcriptase inhibitor widely used to treat patients with human immunodeficiency virus (HIV) and hepatitis B virus (HBV) infection. Despite the excellent safety records of this regimen, a few cases of acute renal failure and Fanconi syndrome have been reported among HIV patients exposed to TDF. In the HBV monoinfection scenario, only two cases of TDF-associated Fanconi syndrome have been reported thus far. Here, we describe two additional patients with chronic hepatitis B (CHB) who developed a TDF-induced Fanconi syndrome that reverted after TDF withdrawal and had viral replication fully suppressed upon switching to entecavir (ETV)...

Antiretroviral medications such as tenofovir have been associated with Fanconi syndrome (FS) usually identified within the first 1-29 months after exposure to the medication. We present a case of life-threatening FS which developed in a 37-year-old woman with HIV after 8 years of asymptomatic tenofovir use. The patient was diagnosed with HIV in 1996 at 20 years of age, hepatitis C 10 years later, and Staphylococcus aureus sepsis with secondary osteomyelitis of the spine 3 years before admission for FS. She developed nausea, vomiting, diarrhea, and generalized weakness over a 2-week time period and presented to the hospital...

Tenofovir disoproxil fumarate (TDF) is an adenine analogue reverse transcription inhibitor widely used in first-line treatment of human immunodeficiency virus (HIV) infection and also in hepatitis B virus infection. Its use has been linked to sporadic Fanconi syndrome, renal failure and bone disease. We present the clinical characteristics of tenofovir-induced osteomalacia, discuss bone biopsy findings, describe predisposing factors and compare our results with other reported cases. We describe five cases of hypophosphatemic osteomalacia induced by TDF and recorded at the rheumatology service of a university hospital between 2010 and 2014...

In human immunodeficiency virus (HIV)-infected patients, tenofovir disoproxil fumarate (TDF) may cause hypophosphatemia leading to osteomalacia due to renal phosphate wasting. Fibroblast growth factor 23 (FGF23) may play a role in this setting. We present an HIV-infected patient with TDF-induced profound hypophosphatemia, Fanconi syndrome, osteomalacia, and bilateral hip fracture. Routine serum biochemistry was assessed by standard methods. The plasma FGF23 concentration was measured at Mayo Laboratories (Scottsdale, AZ, USA)...

We report a 55-year-old female who presented to the emergency department with acute onset quadriparesis. She was diagnosed to have acquired immunodeficiency syndrome 7 years ago and was on tenofovir based anti-retroviral therapy for past 10 months. As the patient also had hypophosphatemia, glucosuria and proteinuria Fanconi syndrome (FS) was suspected. She improved dramatically over next 12 h to regain normal power and also her renal functions improved over next few days. Tenofovir induced FS presenting as hypokalemic paralysis is very rare complication and is the first case reported from India...
