HIV-seroconversion among HIV-1 serodiscordant married couples in Tanzania: a cohort study

Disclosure of HIV Status to Sexual Partners Among People With HIV in Singida Regional Referral Hospital of Tanzania: A Cross-Sectional Study

ABSTRACT

HIV status nondisclosure to sexual partners remains a major challenge in Tanzania's health system. This hospital-based, descriptive, cross-sectional study design recruited 380 people living with HIV (PLWH) to assess voluntary HIV status disclosure to sexual partners, the associated factors, and outcomes among PLWH in Tanzania. Approximately 78% ( n = 297) of the study participants reported disclosing their HIV status to their sexual partners. Adjusted multivariable logistic regression analysis revealed that HIV status disclosure to sexual partners was significantly associated with living with a sexual partner (adjusted odds ratio [AOR] = 3.91, 95% CI [1.43-10.72]), knowledge of HIV disclosure (AOR = 11.71, 95% CI [2.88-47.63]), known serostatus of the sexual partner (AOR = 40.20, 95% CI [15.31-105.56]), and HIV disclosure-related stigma (AOR = 0.92, 95% CI [0.85-0.99]). Addressing these significant factors will maximize the magnitude of voluntary disclosure to sexual partners.

Level of HIV serodiscordance and associated factors among heterosexual couples in Ethiopia: A systematic review and meta-analysis

HIV-related causes accounted for approximately 770,000 deaths globally in 2018. Globally, there were 1.7 million new infections, and approximately 37.9 million people were living with HIV by the end of 2018. According to the WHO 2018 study, the African Region was the most affected, with 25.7 million people living with HIV in 2018. In Africa, married and cohabiting couples have a high prevalence of HIV discordance, ranging from 3% to 20% in the general population. Therefore, it is crucial to understand the level of HIV serodiscordance among married couples in Ethiopia and the contributing factors. Studies were systematically searched, utilizing international databases such as PubMed, Google Scholar, Cochrane Library, and Embase. The level of quality of the included articles, which employed cross-sectional and cohort study designs, was evaluated using the New Castle Ottawa scale. The systematic review employed a random-effects approach, and statistical analysis was conducted using STATA version 17 software. The presence of statistical heterogeneity within the included studies was assessed using the I-squared statistic. The random-effects meta-analysis model was used to estimate the pooled level of HIV serodiscordance. The results were reported following the Preferred Reporting Item for Systematic Review and Meta-Analyses (PRISMA) guideline. A total of ten (10) observational studies were included in this review. The pooled level of HIV serodiscordance among married heterosexual couples in Ethiopia was found to be 11.4% (95% CI = 7% -15.7%). The results from the meta-analysis indicated a significant positive association between HIV serodiscordance and the variables studied. Specifically, consistently using condoms (OR = 1.82; 95% CI: 1.08-2.56), having a CD4 count of >200 cells/mm3 (OR = 1.45; 95% CI: 1.12-1.77), and having a premarital sexual relationship (OR = 1.93; 95% CI: 1.28-2.57) were strongly linked to couples' serodiscordance. To protect a seronegative partner in a serodiscordant relationship from acquiring HIV infection, it is crucial to implement preventive measures. These measures include providing comprehensive health education on the correct and consistent use of condoms, ensuring regular monitoring and care at an antiretroviral therapy (ART) clinic, and offering voluntary counseling and testing (VCT) services to both sexual partners.

Transmission network and phylogenetic analysis reveal older male-centered transmission of CRF01_AE and CRF07_BC in Guangxi, China

In China, the number of newly reported HIV infections in older people is increasing rapidly. However, clear information on the impact of older people on HIV transmission is limited. This study aims to reveal the local HIV transmission patterns, especially how older people affect virus transmission. Subtype analysis based on available pol sequences obtained from HIV patients revealed that CRF01_AE and CRF08_BC were predominant in patients aged <50 years, whereas CRF01_AE was predominant in older people aged ≥50 years (χ²= 29.299, P < 0.001). A total of 25 patients (5.2%, 25/484) were identified with recent HIV infection (RHI). Transmission network analysis found 267 genetically linked individuals forming 55 clusters (2-63 individuals), including 5 large transmission clusters and 12 transmission clusters containing RHI. Bayesian phylogenetic analysis suggested that transmission events in CRF01_AE and CRF07_BC were centred on older males, while transmission events in CRF08_BC were centred on younger males. Multivariable logistic regression analysis showed that older people were more likely to cluster within networks (AOR = 2.303, 95% CI: 1.012-5.241) and that RHI was a significant factor associated with high linkage (AOR = 3.468, 95% CI: 1.315-9.146). This study provides molecular evidence that older males play a central role in the local transmission of CRF01_AE and CRF07_BC in Guangxi. Given the current widespread of CRF01_AE and CRF07_BC in Guangxi, there is a need to recommend HIV screening as part of free national medical examinations for older people to improve early detection, timely treatment, and further reduce second-generation transmission.

HIV-serodifferent couples' perspectives and practices regarding HIV prevention strategies: A mixed methods study

A substantial proportion of heterosexually acquired HIV infections in the U.S. occur between partners in primary relationships characterized by mixed HIV status. The U.S. Centers for Disease Control and Prevention have issued guidelines prioritizing HIV-serodifferent couples for primary HIV prevention, including treatment-as-prevention and pre-exposure prophylaxis (PrEP). Yet, very little research has been conducted to understand the perspectives and practices of HIV-serodifferent couples regarding HIV prevention strategies in the U.S. To help fill this gap, we conducted a mixed methods study with 27 mostly Black/African American and Latinx HIV-serodifferent heterosexual couples residing in New York City to explore their knowledge, attitudes, practices, and perspectives regarding combination HIV prevention, including condoms, PrEP and viral control. All couples expressed the desire to maintain viral suppression in the HIV-positive partner, which was not always achieved. There was considerable heterogeneity in the use of HIV prevention methods by couples; and several patterns emerged that were largely driven by gender and relationship dynamics. Female partners, in particular, expressed high levels of anxiety around transmission of HIV and thus desired multiple methods of protection. Healthcare providers should consider couples' psychosocial well-being, relationship quality, and other motivational factors when helping to tailor HIV preventative care for mixed-status couples.

Socio- demographic correlates of HIV sero-discordance among couples in West Bengal, India; A cross sectional analysis

Serodiscordant couples serves as potential source of Human Immunodeficiency Virus (HIV) transmission. Understanding demographic dynamics of serodiscordant couples plays an important role in tailoring interventions towards eliminating HIV. We conducted this cross sectional analysis in 314 Integrated Counseling and Testing Centres (ICTCs) in West Bengal, India during April 2016 to March 2020. General individuals who were detected as HIV reactive and whose spouses were also tested for HIV comprised the study population (8740 couples). Sociodemographic variables were compared across concordant and discordant arms and also between male positive (M+ F-) and female positive (F+ M-) subgroups of serodiscordant. Among the couples studied, 35.2% (95% CI: 34.2- 36.2 %) were serodiscordant. Among serodiscordant couples, the proportion of M+ F- (86.1%) was significantly higher than F+ M- (13.9%). We observed higher mean ages of couples, higher education, business & service occupations and urban residence as significantly associated with serodiscordance relationship (p < 0.05). Higher mean age of couple and lower proportion of housewives were associated with F+M- subgroup. As around 35% serodiscordant couples carry the risk of transmission to negative spouses particularly in higher age and urban residence, thus reorientation of HIV programme may be required accordingly to avert transmission in future.

"We are in this together:" dyadic-level influence and decision-making among HIV serodiscordant couples in Tanzania receiving access to PrEP

BACKGROUND

A substantial number of new HIV infections in sub-Saharan Africa occur within stable couples. Biomedical prevention (pre-exposure prophylaxis, PrEP) and treatment (antiretroviral therapy, ART) can provide benefits to sexual partners and can be used to prevent infection within HIV serodiscordant couples. However, research is typically focused on individuals, not dyads, even when the intervention may directly or indirectly impact sexual partners. Gaps remain in understanding best practices for recruitment, informed consent, and intervention implementation in studies involving HIV prevention and treatment among heterosexual serodiscordant couples. This qualitative study was undertaken to understand and describe decision-making and dyadic-level influence among members of serodiscordant couples regarding (1) participation in a dyadic-based research study involving HIV self-testing and access to PrEP, and (2) utilization of PrEP and ART.

METHODS

This qualitative study was nested within an observational cohort study assessing the acceptability of home-based couples' HIV self-testing and uptake of dyadic care for serodiscordant couples involving facilitated referral for HIV-positive partners and access to PrEP for HIV-negative partners. Semi-structured in-depth interviews were conducted among a subset of study participants (n = 22) as well as individuals involved in serodiscordant relationships who chose not to participate (n = 9). Interviews focused on couples' decision-making regarding study participation and dyadic-level influence on medication use. Interviews were transcribed verbatim and translated from Kiswahili into English. Data were analyzed using thematic analysis.

RESULTS

Three major themes were identified: (1) HIV as "two people's secret" and the elevated role of partner support in serodiscordant relationships; (2) the intersectional role of HIV-status and gender on decision-making; (3) the relational benefits of PrEP, including psychosocial benefits for the couple that extend beyond prevention.

CONCLUSIONS

The study found that couples made joint decisions regarding study participation and uptake of HIV-related medication. Relational autonomy and dyadic-level influence should be considered within research and programs involving HIV serodiscordant couples.
