To investigate the role of genital shedding of herpesviruses in human immunodeficiency virus type 1 (HIV) transmission, we compared 20 HIV-infected men who did and 26 who did not transmit HIV to their sex partners. As described previously, HIV transmission was associated with the potential source partner having higher levels of HIV RNA in blood and semen, having lower CD4(+) T cell counts, having bacterial coinfections in the genital tract, and not using antiretroviral therapy. This study extended these findings by observing significant associations between HIV transmission and the following characteristics, especially among therapy-naive potential source partners: seminal cytomegalovirus (CMV) shedding, seminal Epstein-Barr virus shedding, and levels of anti CMV immunoglobulin in blood plasma.

Characterization of serological responses to Plasmodium falciparum (Pf) is of interest to understand disease burden and transmission dynamics; however, their interpretation is challenging. Dried blood spots from 30,815 participants aged 6 months to 15 years from the 2018 Nigeria HIV/AIDS Indicator and Impact Survey were analyzed by multiplex bead-based assay to measure immunoglobulin G (IgG) to Pf-stage-specific MSP-1, AMA-1, GLURPR0, LSA-1, and CSP. These IgG levels were analyzed by principal component analysis (PCA).

The gastrointestinal tract is a prominent portal of entry for HIV-1 during sexual or perinatal transmission, as well as a major site of HIV-1 persistence and replication. Elucidation of underlying mechanisms of intestinal HIV-1 infection are thus needed for the advancement of HIV-1 curative therapies. Here, we present a human 2D intestinal immuno-organoid system to model HIV-1 disease that recapitulates tissue compartmentalization and epithelial-immune cellular interactions.

Introduction: An unintended pregnancy refers to a situation where a pregnancy occurs either when there is no desire for a child (unwanted) or when it takes place at a time that was not anticipated (mistimed). Pregnant women infected with HIV face a two to tenfold increased risk of mortality during both pregnancy and the postpartum period compared to those who are not infected. A national level cohort study has identified that about 70 babies born HIV positive, 60% of them were from unplanned pregnancy.

To explore differences among the elderly people (aged over 50 years old) living with HIV (PLWH) who are receiving antiretroviral therapy (ART), we collected and analyzed data using cross-sectional research methods. Among 520 elderly PLWH on ART, those over 60 years old, compared to those aged 50-60, had lower levels of education, more retirees in occupation distribution, a lower rate of active consultation, a higher proportion of heterosexual transmission, and more complications. Additionally, this study demonstrated a greater incidence of severe disease symptoms and a higher rate of ART failure.

Background: Rapid diagnostic tests (RDTs) based on the detection of Plasmodium falciparum histidine rich protein 2 (PfHRP2) are widely used for the diagnostic of P. falciparum in Africa. However, deletions of the pfhrp2 and pfhrp3 genes can lead to false negative test results and compromise appropriate case management.
