Patients with HIV have a higher incidence of rhabdomyolysis compared with the HIV negative population because of medication-related myotoxicity and drug-drug interactions. Statins and antiretroviral therapy have been previously reported to cause myopathy in patients with HIV when used alone or in combination. In this study, we describe a case of biopsy-proven noninflammatory and nonautoimmune myopathy associated with the use of simvastatin and Genvoya (elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide fumarate) and review 3 previously reported similar cases...

We estimated list and net prices for tenofovir disoproxil fumarate (TDF) products Truvada, Complera, and Stribild, and their tenofovir alafenamide (TAF) versions Descovy, Odefsey, and Genvoya. Gilead offered discounts for Descovy that resulted into lower net prices compared to Truvada. This strategy encouraged patients switching from Truvada to Descovy before the availability of generic Truvada. Conversely, Gilead offered lower discounts for Odefsey and Genvoya, which resulted into higher net prices compared to Complera and Stribild...

ANAMNESIS:  We saw a previously healthy 30-year-old Southeast-Asian sailor with progredient coughing and fever. EXAMINATION:  We found an atypical pneumonia along with a positive HIV-test. We performed a bronchial lavage and further diagnostics for opportunistic infections. The lab work showed a viral load of 3340 000 copies/ml and a CD4-cell-count of 36/µl. DIAGNOSIS:  HIV late presenter in CDC stadium C3 with Pneumocystis jirovecii and CMV pneumonia...

Toxicological data on overdose with HIV-inhibitors is scarce. We present a case report of two independent suicide attempts by self-administered overdose with the same antiretroviral medicine Genvoya® (emtricitabine/elvitegravir/tenofovir alafenamide/cobicistat). Both patients were admitted to the hospital and presented with a loss of consciousness, lactic acidosis, elevated hepatic transaminase levels and hemodynamic instability. While one patient survived with advanced supportive measures, the other passed away...

Tenofovir alafenamide (TAF) is a prodrug of tenofovir as a potent nucleotide reverse transcriptase inhibitor. It serves as the key component of Genvoya® for the first-line treatment of human immunodeficiency virus infection (HIV) and is the active component of Vemlidy® for the treatment of chronic hepatitis B. Vemlidy® is also a monotherapeutic regimen formulated as TAF hemifumarate ( 1 ; TAF:fumarate = 2:1). In this work, we report for the first time the single-crystal structure of TAF fumarate hemihydrate ( 2 , TAF:fumarate:H2 O = 2:2:1)...

HIV integrase strand transfer inhibitors (INSTI) are considered well tolerated with few treatment-limiting adverse effects. However, emerging data from clinical trials has identified excessive weight gain possibly due to INSTI alone or with tenofovir alafenamide as a new and possible long-term complication of combination antiretroviral therapy (cART). Identifying who is at greatest risk and whether the unintended weight gain is reversible remain unanswered questions. We report a return to baseline weight after switching back to tenofovir disoproxil/emtricitabine/efavirenz (Atripla®) in a woman who had profound weight gain due to tenofovir alafenamide/emtricitabine/cobicistat/elvitegravir (Genvoya®)...

Objective: We report the first known case of Cushing syndrome and secondary adrenal insufficiency in a patient with concomitant use of epidural triamcinolone and Genvoya® (elvitegravir 150 mg/cobicistat 150 mg/emtricitabine 200 mg/tenofovir alafenamide 10 mg) for the human immunodeficiency viruses (HIV). The prompt recognition of this drug-drug interaction is critical to avoid adverse outcomes when glucocorticoids are used with anti-retroviral treatment containing cobicistat, a potent cytochrome P450 3A (CYP3A4) inhibitor...

We report a novel case of severe bilateral panuveitis with hypopyon secondary to rifabutin and cobicistat drug interaction in the setting of human immunodeficiency virus (HIV) infection and latent tuberculosis (TB). A 63-year-old woman presented with bilateral conjunctival injection and decreasing vision of 5 days' duration. She had a history of well-controlled HIV infection, latent TB, and non-alcoholic steatohepatitis for which she was inadvertently being treated, due to a pharmacy error, concurrently with the anti-TB medicine rifabutin and the highly active antiretroviral therapy combination Genvoya® (elvitegravir 150 mg - cobicistat 150 mg - emtricitabine 200 mg - tenofovir alafenamide 10 mg)...

BACKGROUND: Genvoya® (elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide) is a recent single regimen for the treatment of Human Immunodeficiency Virus (HIV). However, because of its complexity, it is difficult to predict drug interactions, especially when associated with HMG-CoA reductase inhibitors and/or in the setting of other comorbidities. We discuss the mechanisms of these potential drug interactions as the cause of rhabdomyolysis and acute kidney injury in the context of prior and current medication therapy with possible underlying liver and kidney dysfunction...

Human immunodeficiency virus (HIV) patients are often diagnosed in the chronic stage of HIV/AIDS. Combination antiretroviral therapy (cART) has improved quality of life for HIV-infected patients. Present study describes a novel long-acting parenteral formulation of combination antiretroviral (cARV) loaded nano-drugs for treating chronic HIV-1 (cHIV) in a humanized-BLT (hu-BLT) mice model. The cARV (elvitegravir+tenofovir alafenamide+emtricitabine; EVG+TAF+FTC) drugs (mimicking marketed Genvoya® one-pill for HIV-treatment) were encapsulated in poly (lactic-co-glycolic acid) nanoparticles (NPs)...

A liquid chromatography with triple quadrupole mass spectrometry method was developed and validated for the determination of tenofovir and tenofovir alafenamide concentrations in human plasma and cerebrospinal fluid. Tenofovir and tenofovir alafenamide were extracted from matrix by solid phase extraction. The dried extraction eluents were dissolved in water for LC-MS/MS analysis. Separation was achieved with a Phenomenex Synergi 4 μm Polar-RP 80A column (50 × 2 mm) with a gradient elution of 0.1% formic acid in water and acetonitrile...

Tenofovir (TFV) is the cornerstone of the treatment and prophylaxis of HIV infections. It has been routinely used in its prodrug form TDF (tenofovir disoproxil fumarate) combined with emtricitabine ((-)FTC) and other antiretroviral agents. TDF has now been replaced by TAF (tenofovir alafenamide) which allows better uptake by the lymphoid tissue. In combination with elvitegravir (E), cobicistat (C), emtricitabine (F), TAF can be advocated as an STR (single tablet regimen, Genvoya®) for the treatment of HIV infections...

Antiretroviral (ART) therapy for the treatment of human immunodeficiency virus (HIV) infection has undergone significant changes over the past 30 years. Many single-tablet regimens (STRs), including newer fixed-dose combination (FDC) tablets, are available, offering patients several options for choosing a treatment regimen that works best for them. Given these changes, patients are more likely to adhere to treatment, achieve better clinical outcomes, and experience both fewer side effects and drug-drug interactions...

Salmonella meningitis is a rare manifestation of meningitis typically presenting in neonates and the elderly. This infection typically associates with foodborne outbreaks in developing nations and AIDS-endemic regions. We report a case of a 19-year-old male presenting with altered mental status after 3-day absence from work at a Wisconsin tourist area. He was febrile, tachycardic, and tachypneic with a GCS of 8. The patient was intubated and a presumptive diagnosis of meningitis was made. Treatment was initiated with ceftriaxone, vancomycin, acyclovir, dexamethasone, and fluid resuscitation...

Tenofovir alafenamide (tenofovir AF) is a novel oral prodrug of the nucleos(t)ide reverse transcriptase inhibitor (NRTI) tenofovir that has several pharmacological advantages over tenofovir disoproxil fumarate (tenofovir DF), including increased plasma stability and reduced tenofovir systemic exposure. Tenofovir AF has been coformulated with elvitegravir, cobicistat and emtricitabine as a once-daily, single-tablet regimen (elvitegravir/cobicistat/emtricitabine/tenofovir AF; Genvoya(®)) for the treatment of adults and adolescents with HIV-1 infection...

Tenofovir alafenamide (TAF) can be considered a new prodrug of tenofovir (TFV), as successor of tenofovir disoproxil fumarate (TDF). It is in vivo as potent against human immunodeficiency virus (HIV) at a 30-fold lower dose (10mg) than TDF (300mg). TAF has been approved in November 2015 (in the US and EU), as a single-tablet regimen (STR) containing 150mg elvitegravir (E), 150mg cobicistat (C), 200mg emtricitabine [(-)FTC] (F) and 10mg TAF, marketed as Genvoya®, on 01 March 2016 in the US as an STR containing 25mg rilpivirine (R), 200mg F and 25mg TAF, marketed as Odefsey®, and on 4 April 2016 in the US, as an STR containing 200mg F and 25mg TAF, marketed as Descovy®, for the treatment of HIV infections...
