OBJECTIVE The 2010 WHO antiretroviral therapy (ART) guidelines have resulted in increased tenofovir use. Little is known about tenofovir-induced chronic kidney disease (CKD) in HIV-infected Vietnamese with mean body weight of 55 kg. We evaluated the prevalence and risk factors of CKD in this country. DESIGN Cross-sectional study was performed. METHODS Clinical data on HIV-infected Vietnames...
Simian immunodeficiency virus (SIV) infection of infant macaques is a useful animal model of pediatric HIV infection to evaluate the potential of chemoprophylactic regimens to reduce mother-to-infant transmission of HIV. Previous studies have demonstrated that short-term subcutaneous administration of the reverse transcriptase inhibitor tenofovir was highly effective in protecting newborn macaq...
BACKGROUND Plasma concentrations of tenofovir increase when the drug is coadministered with some ritonavir-boosted protease inhibitors (PI/r). We hypothesized that tenofovir disoproxil fumarate (TDF)-treated patients taking PI/r-based regimens would have a greater decline in renal function than patients receiving nonnucleoside reverse-transcriptase inhibitor (NNRTI)-based therapy. METHODS We ...
BACKGROUND The rectum is particularly vulnerable to HIV transmission having only a single protective layer of columnar epithelium overlying tissue rich in activated lymphoid cells; thus, unprotected anal intercourse in both women and men carries a higher risk of infection than other sexual routes. In the absence of effective prophylactic vaccines, increasing attention is being given to the use ...
The 2009 update of the American Association for the Study of Liver Diseases (AASLD) Practice Guidelines for Management of Chronic Hepatitis B are now posted online at www.aasld.org. This is the fourth version of this guideline; the last version was published in 2007.1 The key changes in the 2009 version are new recommendations for first-line and second-line antiviral agents. Since the last upda...

Rectal microbicides are being developed to prevent new HIV infections in both men and women. We focused our in vivo preclinical efficacy study on rectally-applied tenofovir. BLT humanized mice (n = 43) were rectally inoculated with either the primary isolate HIV-1JRCSF or the MSM-derived transmitted/founder (T/F) virus HIV-1THRO within 30 minutes following treatment with topical 1% tenofovir or...
BACKGROUND The latest World Health Organization guidelines recommend replacing stavudine with tenofovir or zidovudine in first-line antiretroviral therapy in resource-limited settings. We report on outcomes and toxicities among patients on these different regimens in a routine treatment cohort in Lesotho. METHODS All adult patients initiating antiretroviral therapy from January 1, 2008, to De...
BACKGROUND Tenofovir with full-dose didanosine has been associated with paradoxical CD4 + T cell decrease despite virological suppression. We investigated whether tenofovir plus didanosine at a weight-adjusted dosage could be responsible for such an effect, and factors associated with CD4 + T cell count evolution under this combination. METHODS This was a prospective observational multicohort...
We report 3 cases of renal toxicity associated with use of the antiviral agent tenofovir. Renal failure, proximal tubular dysfunction, and nephrogenic diabetes insipidus were observed, and, in 2 cases, renal biopsy revealed severe tubular necrosis with characteristic nuclear changes. Patients receiving tenofovir must be monitored closely for early signs of tubulopathy (glycosuria, acidosis, mil...
