Short Communication: Discordance of HIV-1 Viral Load from Paired Blood and Seminal Plasma Samples in a Chinese Men Who Have Sex with Men Population

Decay kinetics of HIV-1-RNA in seminal plasma with dolutegravir/lamivudine versus dolutegravir plus emtricitabine/tenofovir alafenamide in treatment-naive people living with HIV

BACKGROUND

This was a substudy of a Phase IV, randomized clinical trial (ClinicalTrials.gov identifier: NCT04295460) aiming to compare the activity of dolutegravir/lamivudine versus dolutegravir plus tenofovir alafenamide/emtricitabine (DTG + TAF/FTC) in the male genital tract.

METHODS

Participants were asymptomatic adults without sexually transmitted diseases, treatment-naive people living with HIV (PLWH), with CD4+ T cell counts >200 cells/mm3 and plasma HIV-1-RNA levels >5000 and <500 000 copies/mL, randomized (1:1) to DTG + TAF/FTC or dolutegravir/lamivudine. Blood plasma (BP) and seminal plasma (SP) were collected at baseline and Weeks 4, 8, 12 and 24. HIV-1-RNA was measured in BP and SP using the Cobas 6800 system (Roche Diagnostics) with a lower detection limit of 20 copies/mL. The primary efficacy endpoint was the proportion of subjects with undetectable SP HIV-1-RNA at Week 12 by intention-to-treat analysis.

RESULTS

Fifteen participants in the DTG + TAF/FTC and 16 in the dolutegravir/lamivudine arms were analysed, with basal SP viral load of 4.81 (4.30-5.43) and 4.76 (4.09-5.23), P = 0.469, respectively. At Week 12, only one participant in each treatment arm had a detectable SP HIV-1-RNA (DTG + TAF/FTC, 141 copies/mL; dolutegravir/lamivudine, 61 copies/mL). Based on the estimated means, there was no significant difference in the decay of HIV-1-RNA in both BP and SP over time between the two arms of treatment (F = 0.452, P = 0.662, and F = 1.147, P = 0.185, respectively).

CONCLUSIONS

After 12 weeks of treatment, there were no differences in the percentage of undetectable SP HIV-1-RNA in naive PLWH who started dolutegravir/lamivudine compared with DTG + TAF/FTC.

Users' Concerns Related to Online HIV Counseling in South Korea: A Descriptive Qualitative Study

This qualitative descriptive study was designed to identify HIV-related questions frequently asked by online counseling users seeking professional advice. Data were collected via a public online question/answer counseling website operated by the Gyeonggi-do branch of the Korean Association for AIDS Prevention. Data on users' questions regarding HIV were collected between January 1, 2017, and December 31, 2018. The online questions were then analyzed and divided into codes and categories. From the 559 questions submitted, content analysis identified four major categories related to HIV: (a) HIV testing, (b) self-perceived HIV risk and risky sexual behaviors, (c) positive and negative emotional states, and (d) treatment and prevention. This study indicates that online counseling can be used to provide tailored information related to HIV along with emotional and psychosocial support to reach different subgroups and to provide current information such as the use of pre-exposure prophylaxis for those seeking professional advice.
