BACKGROUND & AIMS Therapy of chronic hepatitis B with HBV-polymerase inhibitors, in particular tenofovir or adefovir, may affect renal function. To assess renal function more accurately in the normal range, we used the recently validated, Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formula to calculate the estimated glomerular filtration rate (eGFR). METHODS Patient subgroups ...
Previous studies have shown that strawberry extract increases the transepithelial transport of tenofovir disoproxil, an esterase-sensitive prodrug of the antiviral compound tenofovir (formerly PMPA), across Caco-2 monolayers. This increase in transport was at least partially due to inhibition of its intestinal metabolism. To further study the feasibility of this absorption enhancing strategy, t...
BACKGROUND All international guidelines suggested that Tenofovir and Entecavir are the primary drugs at the first line therapy for the treatment of chronic hepatitis B (CHB). However, in Turkey these medications reimbursed at the second line therapy according to the Healthcare Implementation Notification. The aim of this study is to compare the cost effectiveness of oral antiviral treatment str...
BACKGROUND Treatment with tenofovir is sometimes associated with renal dysfunction. Limited information is available on this side effect in patients with small body weight, although the use of tenofovir will spread rapidly in Asia and Africa, where patients are likely to be of smaller body weight. METHODS In a single-center cohort, Japanese patients with HIV infection who started tenofovir-co...
Pharmacokinetic study of tenofovir disoproxil fumarate combined with rifampin in healthy volunteers.
Tenofovir disoproxil fumarate (tenofovir DF) was studied in combination with rifampin in 24 healthy subjects in a multiple-dose, open-label, single-group, two-period study. All subjects were given tenofovir DF at 300 mg once a day (QD) from days 1 to 10 (period 1). From days 11 to 20 the subjects received tenofovir DF at 300 mg combined with rifampin at 600 mg QD (period 2). The multiple-dose p...
Tenofovir disoproxil fumarate (DF) is a potent nucleotide analog reverse transcriptase inhibitor approved for the treatment of human immunodeficiency virus (HIV)-infected adults. The single-dose and steady-state pharmacokinetics of tenofovir were evaluated following administration of tenofovir DF in treatment-experienced HIV-infected children requiring a change in antiretroviral therapy. Using ...
INTRODUCTION Resistance of the reverse transcriptase (RT) of hepatitis B virus (HBV) to the tenofovir nucleotide drug has not been observed since its introduction for treatment of hepatitis B virus (HBV) infection in 2008. In contrast, frequent viral breakthrough and resistance has been documented for adefovir. Our computational study addresses an inventory of the structural differences between...
BACKGROUND WHO recommends using Tenofovir containing first line antiretroviral therapy (ART), however, Tenofovir has been reported to be associated with renal impairment and dysfunction. We compared renal function among individuals on Tenofovir and those on non-Tenofovir containing ART. METHODS In a cross-sectional study of HIV-Positive adults on ART, at enrolment into a prospective cohort to...
Introduction : Sarcopenia is defined as a loss of muscle mass and strength. ATP homeostasis crucial during myogenesis. We determined how the purinergic system modulates myogenesis using dipyridamole (blocks adenosine taken up by cells) tenofovir (inhibits release) in myoblast cell line. Methods: C2C12 cells were differentiated presence/absence tenofovir/dipyridamole, with/without A2B selective ...
Tenofovir disoproxil fumarate (TDF) causes bone, endocrine, and renal changes by an unknown mechanism(s). Data are limited on tenofovir pharmacokinetics and these effects. Using baseline data from a multicenter study of HIV-infected youth on stable treatment with regimens containing TDF (n = 118) or lacking TDF (n = 85), we measured cross-sectional associations of TDF use with markers of renal ...
