Dolutegravir + Lamivudine vs. Dolutegravir + Tenofovir Disoproxil Fumarate/Emtricitabine: Very-Low-Level HIV-1 Replication through 144 Weeks in the GEMINI-1 and GEMINI-2 Studies.

In GEMINI-1/-2, dolutegravir + lamivudine was non-inferior to dolutegravir + tenofovir disoproxil fumarate/emtricitabine (TDF/FTC) in achieving viral suppression (viral load [VL] < 50 copies/mL) in treatment-naive adults. Abbott's RealTime HIV-1 assay provides quantitative VL (40-10,000,000 copies/mL) and qualitative target detected or target not detected (TND) for VL < 40 copies/mL. This post hoc analysis assessed very-low-level viremia and "blips" through Week 144.

Integrase Inhibitor Resistance Mechanisms and Structural Characteristics in Antiretroviral Therapy-Experienced, Integrase Inhibitor-Naive Adults with HIV-1 Infection Treated with Dolutegravir plus Two Nucleoside Reverse Transcriptase Inhibitors in the DAWNING Study.

At week 48 in the phase IIIb DAWNING study, the integrase strand transfer inhibitor (INSTI) dolutegravir plus 2 nucleoside reverse transcriptase inhibitors demonstrated superiority to ritonavir-boosted lopinavir in achieving virologic suppression in adults with HIV-1 who failed first-line therapy. Here, we report emergent HIV-1 drug resistance and mechanistic underpinnings among dolutegravir-treated adults in DAWNING. Population viral genotyping, phenotyping, and clonal analyses were performed on participants meeting confirmed virologic withdrawal (CVW) criteria on dolutegravir-containing regimens.

A multistate trial of pharmacy syringe purchase.

Pharmacies are a potential site for access to sterile syringes as a means for preventing human immunodeficiency virus (HIV), but the type and extent of their utility is uncertain. To examine pharmacy syringe purchase, we conducted a standardized, multistate study in urban and rural areas of four states in which attempts to purchase syringes were documented. Of 1,600 overall purchase attempts, 35% were refused.

Pharmacist ambivalence about sale of syringes to injection drug users.

Objective: To examine pharmacists' attitudes and practices surrounding human immunodeficiency virus (HIV) prevention among injection drug users.

Design: Focus groups.

Setting: Urban and rural sites in Colorado, Connecticut, Kentucky, and Missouri.
