Simplifying antiretroviral therapy to lopinavir/ritonavir monotherapy did not improve quality of life and therapy adherence in pretreated HIV-infected children.

We reported quality of life (QOL) and adherence in HIV-infected children after simplifying the antiretroviral regimen by switching to lopinavir/ritonavir monotherapy (mLPV/r). HIV-infected children with HIV-RNA <50 copies/ml while using second-line double boosted protease inhibitors were switched to mLPV/r. Primary caregivers completed PACTG QOL questionnaires at weeks 0, 48, 96, and 144.

Use of human papillomavirus DNA, E6/E7 mRNA, and p16 immunocytochemistry to detect and predict anal high-grade squamous intraepithelial lesions in HIV-positive and HIV-negative men who have sex with men.

Background: Men who have sex with men (MSM) are at high risk of having anal cancer. Anal high-grade squamous intraepithelial lesion (HSIL) is the precursor of anal cancer. We explored the use of different biomarkers associated with human papillomavirus (HPV) infection and HPV-mediated cell transformation to detect and predict HSIL among HIV-positive and HIV-negative MSM.

Comparisons between validated estimated glomerular filtration rate equations and isotopic glomerular filtration rate in HIV patients.

Objective: Understanding how best to measure renal function in HIV-infected patients is critical because estimated glomerular filtration rate (eGFR) in HIV-infected patients can be affected by ethnicity and body composition. We validated the available eGFR equations and compared them to the plasma Tc-diethylenetriaminepentaacetic acid (Tc-DTPA) clearance in HIV-infected patients.

Design: Test of diagnostic accuracy.

High prevalence of lipid abnormalities among antiretroviral-naive HIV-infected Asian children with mild-to-moderate immunosuppression.

Background: Dyslipidaemia is a common complication among HIV-infected children after antiretroviral therapy (ART); however, HIV itself can cause abnormal lipid metabolism. There is limited information of lipid profiles among Asian HIV-infected children naive to ART.

Methods: A total of 274 HIV-infected ART-naive Thai and Cambodian children aged 1-12 years with CD4% between 15% and 24% were included.

Neither branded nor generic lopinavir/ritonavir produces adequate lopinavir concentrations at a reduced dose of 200/50 mg twice daily.

We assessed pharmacokinetic (PK) parameters of reduced dose lopinavir/ritonavir (LPV/r) and compared generic and branded tablets. Twenty HIV-infected patients using protease inhibitors with HIV RNA <50 copies per milliliter were randomized to generic or branded LPV/r 200/50mg twice daily (BID). At week 2, PK-sampling was performed.

Monoboosted lopinavir/ritonavir as simplified second-line maintenance therapy in virologically suppressed children.

Background: Monoboosted protease inhibitor is being evaluated as a strategy to simplify therapy in virologically suppressed patients who are on complex regimens.

Methods: Children with two consecutive HIV-RNA below 50 copies/ml at least 3 months apart while on double boosted protease inhibitor (dPI) were switched to monoboosted lopinavir/r (mLPV/r). The previous dPI regimen was resumed within 4 weeks in children who experienced virological failure defined as two HIV-RNA at least 500 or three HIV-RNA at least 50 copies/ml.
