AI Article Synopsis
- A study aimed to assess how maternal HIV-1 RNA levels around delivery impact disease progression in infants infected with the virus, analyzing data from 574 HIV-1 positive infants.
- Findings revealed that higher maternal HIV-1 RNA levels significantly increased the risk of disease progression and mortality in infants, especially during the first 6 months of life.
- The research concluded that maternal HIV-1 RNA is a strong predictor of early disease progression in infected infants, correlating with their early viral load.
Article Abstract
Objective: To evaluate whether maternal human immunodeficiency virus type 1 (HIV-1) RNA levels in the serum/plasma of mothers at or close to the time of delivery affects the rate of disease progression among vertically HIV-1-infected children and whether it correlates with other parameters affecting infant disease progression.
Methods: International meta-analysis of eight studies with 574 HIV-1 infected infants with available maternal HIV-1 RNA measurements at or close to delivery and clinical follow-up. The primary outcome was disease progression (stage C disease or death, n = 178). Cohort-stratified Cox models were used.
Results: Higher maternal HIV-1 RNA level at or close to delivery significantly increased disease progression risk [hazard ratio (HR), 1.25; 95% confidence interval (CI), 1.04-1.52 per 1 log10 increase; P = 0.02) with a borderline effect on mortality (HR, 1.26; 95% CI, 0.96-1.65; P = 0.10]. The association with disease progression risk was strong in the first 6 months of life (HR, 1.77; 95% CI, 1.28-2.45; P = 0.001), but not subsequently (HR, 1.03; 95% CI, 0.81-1.30). Maternal HIV-1 RNA, early infant HIV-1 RNA (at 30-200 days after birth) and infant CD4 were independent predictors of disease progression in the first 6 months. Maternal HIV-1 RNA at or close to delivery correlated with early infant HIV-1 RNA (r = 0.26, P < 0.001). Effects were independent of maternal and infant treatment.
Conclusions: Higher maternal HIV-1 RNA at or close to delivery strongly predicts disease progression for HIV-1-infected infants, especially in their first 6 months of life and correlates with the early peak of viremia in the infected child.

Background: Doravirine is licensed in patients living with HIV (PWH) harbouring no prior resistance to any NNRTIs. We aimed to evaluate in real life the efficacy of doravirine with prior NNRTI virological failure and NNRTI resistance-associated mutations (RAMs).
Methods: This observational study included PWH switched to a doravirine-containing regimen between 30 September 2019 and 1 May 2022, with an HIV-1 RNA of ≤50 copies/mL and past NNRTI-RAMs.
Background: Due to the unique geographical and climatic conditions in Nagqu (Tibet), the blood station laboratory was only fully established and accredited by 2020. This study validated the performance of the laboratory's blood screening system and analyzed recent trends in blood donation and screening effectiveness.
Methods: Various serum samples were used to assess the performance of hepatitis B, hepatitis C, HIV, and syphilis tests, both serological and nucleic acid tests.
HIV-1 DNA Genotypic Drug Resistance Testing Guides Antiretroviral Therapy in Patients with Low-Level Viremia.

In 2023, we published a case study involving a 10-year-old HIV-1-infected child with low-level viremia (LLV). We showed that this child patient achieved successful viral suppression by modifying the antiretroviral therapy (ART) regimen according to the HIV-1 DNA genotypic drug resistance testing. In this study, we aimed to address whether HIV-1 DNA genotypic drug resistance testing could direct successfully virological suppression in HIV-1-infected patients experiencing persistent LLV based on evidence from a cohort study.

Background: Dual regimen dolutegravir/lamivudine (DOL/3TC) showed potent efficacy and favourable safety in both antiretroviral therapy-naïve and -experienced patients, but data from real life about naive people with high-level viremia are still lacking.
Methods: We performed a retrospective cohort study of people living with HIV (PLWH) who were naive to antiretroviral therapy, had baseline HIV-1 RNA ranging from 100000 to 500000 copies/mL, and initated DOL/3TC. Virological efficacy and changes in immunological parameters after 12 months of treatment were evaluated and compared with highly viremic PLWH who started a triple antiretroviral combination.
Unlabelled: -methyladenosine (m A) is the most prevalent cellular mRNA modification and plays a critical role in regulating RNA stability, localization, and gene expression. m A modification plays a vital role in modulating the expression of viral and cellular genes during HIV-1 infection. HIV-1 infection increases cellular RNA m A levels in many cell types, which facilitates HIV-1 replication and infectivity in target cells.
