Barriers and facilitators to uptake and persistence on prep among key populations in Southern Province, Zambia: a thematic analysis.

BACKGROUND: Especially in high HIV prevalence contexts, such as Zambia, effective biomedical prevention tools are needed for priority populations (PPs), including key populations (KPs), who are at higher risk. HIV pre-exposure prophylaxis (PrEP) has been scaled up nationally in Zambia, but little is known about barriers to PrEP use among specific PPs to date. METHODS: To understand barriers and facilitators to PrEP use in Zambia, we conducted a qualitative case study of PrEP services to PPs including sero-discordant couples (SDCs), female sex workers (FSWs), and men who have sex with men (MSM) in Livingstone. The study conducted in 2021 included in-depth interviews (n = 43) guided by the socio-ecological model, and focus group discussions (n = 4) with clinic and community-based providers and PrEP-eligible clients including users and non-users across PP groups. We used thematic analysis to analyze data using codes derived both deductively and inductively. RESULTS: We found multilevel barriers and facilitators to PrEP use. Cross-cutting barriers shared across PP groups included amplifying effects of PrEP being mistaken for antiretroviral drugs used to treat HIV, including anticipated stigma, and concerns about side-effects based on both misinformation and experience. In addition, stigmatized identities, particularly that of MSM, served as a barrier to PrEP use. The fear of being mislabeled as having HIV was of greatest concern for FSWs. Facilitators to PrEP use primarily included the importance of confidential, KP-sensitive services, and the role of informed, supportive family, friends, and peers. Participants across all PP groups urged expanded education efforts to increase awareness of PrEP within the general population toward mitigating concerns of being mislabeled as living with HIV. CONCLUSION: To our knowledge, this is the first qualitative study of the PrEP cascade among multiple PPs in Zambia. This study provides important explanation for the low rates of PrEP continuation found in earlier demonstration trials among KPs in Zambia. The study also offers recommendations for programming efforts going forward such as inclusive PrEP awareness campaigns, expanded KP sensitivity training, and related efforts to thwart PrEP stigma while expanding access.

HIV transmission in sero-discordant couples with the HIV-positive partner in Xinjiang: incidence and associated predictors.

INTRODUCTION: To control the spread of human immunodeficiency virus (HIV) among sero-discordant couples, we explored the HIV seroconversion and its contributing factors. METHODOLOGY: We recruited negative partners in HIV sero-discordant couples to established a prospective cohort between January 2010 and June 2015 from areas with severe HIV epidemic in Xinjiang. Follow up once every 3 months, serological tests and risk behavior surveys every 6 months. Variables were screened by LASSO regression and a Cox proportional hazards model was established. RESULTS: A total of 1162 negative partners of sero-discordant couples were recruited. The seroconversion occurred in 42 negative partners during follow-up period, with a seroconversion rate of 2/100 (95% CI = 1.21-2.27), and the median time for seroconversion was 0.92 years. The Cox model showed that frequency of sexual behavior for nearly six months, consistent condom use, knowledge of the transmission route for HIV, a history of sexually transmitted diseases, recent CD4 + T lymphocyte count were all significant contributing factors to the seroconversion in negative partner of HIV sero-discordant couples. In addition, the Cox model was used to evaluate the risk factors of seroconversion for HIV negative partners. CONCLUSIONS: The seroconversion rate of HIV negative partners in Xinjiang was lower. The LASSO Cox model may accurately predict the risk of HIV transmission in sero-discordant couples.

Treatment for HIV prevention study in southwestern areas of China.

BACKGROUND: China has ambitious to achieve significant reductions in HIV transmission and HIV-related mortality by adopting the World Health Organization's "Treat All" approach. Such a prevention strategy is needed future study on regional scale. METHODS: An observational cohort study of HIV epidemiology and treatment databases was used to study the effectiveness of antiretroviral therapy on the transmission of HIV in serodiscordant couples in Guangxi of China. RESULTS: A total of 7713 couples were entered into the cohort study analysis which included 1885 couples in the treatment-naive cohort and 5828 couples in the treated cohort. During the follow-up of 18985.29 person-years from 2003 to 2014, the average incidence of HIV was 2.4 per 100 person-years (95% CI 2.1-2.6). HIV seroincidence rate was significantly higher among the treatment naive group (4.2 per 100 person-years, 3.7-4.8) compared with the on treatment group (1.6 per 100 person-years, 1.3-1.8). An overall 45% reduction in risk of HIV transmission among serodiscordant couple was associated with ART treatment (adjusted Hazard Ratio [HR] 0.55, 95% Confidence Interval [CI] 0.44-0.69). Treatment prevention had significantly effectiveness for most baseline characteristics of index partners, such as for male, female, age above 25 years, education below high school, farmer, infected by heterosexual intercourse. CONCLUSION: Treatment-as-prevention can be implemented in the real-world on a national or regional scale, but ART adherence and comprehensive harm reduction while implementing this strategy require further study.

"How can I tell?" Consequences of HIV status disclosure among couples in eastern African communities in the context of an ongoing HIV "test-and-treat" trial.

People living with HIV/AIDS anticipate HIV-related stigma and fear disclosure to intimate partners. Yet, disclosure is critical to reducing HIV transmission and improving care engagement. This qualitative study characterized HIV disclosure experiences and normative beliefs among couples in communities participating in an HIV test-and-treat trial in Kenya and Uganda (Sustainable East Africa Research in Community Health, NCT#01864603). In-depth interviews were conducted with care providers (n = 50), leaders (n = 32) and members (n = 112) of eight communities. Data were analyzed using grounded theoretical approaches and Atlas.ti software. Findings confirmed gender differences in barriers to disclosure: while both men and women feared blame and accusation, women also feared violence and abandonment ("I did not tell my husband because [what if] I tell him and he abandons me at the last moment when I am in labor?"). Positive consequences included partner support for increased care-seeking and adherence ("My husband keeps on reminding me 'have you taken those drugs?'") Yet negative consequences included partnership dissolution, blame, and reports of violence ("some men beat their wives just because of that [bringing HIV medications home]"). Among HIV-infected individuals in discordant relationships, men more often reported supportive spouses ("we normally share [HIV-risk-reduction strategies] since I have been infected and she is HIV negative"), than did women ("my husband refused to use condoms and even threatened to marry another wife"). Care providers lent support for HIV-positive women who wanted to engage partners in testing but feared negative consequences: "They engaged the two of us in a session and asked him if we could all test." Findings demonstrate differing experiences and support needs of women and men living with HIV in eastern Africa, with HIV-positive women in discordant couples particularly vulnerable to negative consequences of disclosure. Efforts to strengthen capacity in health systems for gender-sensitive clinician- or counselor-assisted disclosure should be accelerated within test-and-treat efforts.

Socio-Demographic and Behavioral Factors Associated with the Desire to Procreate Among Patients Living with HIV in Gabon.

The desire to procreate in patients living with HIV (PLHIV) has been seldom investigated in Africa, particularly in Gabon. The aim of this transversal and descriptive study was to analyze the socio-demographic and behavioral factors associated with a desire to have children in a cohort of PLHIV. The study included 442 patients, predominantly females [79.9% (337/422)], and those with a secondary school education [64.2% 271/422)]. The highest prevalence of HIV was found in patients aged 30-39 years old (44.3%), of which 59% (249/422) were unemployed. The desire to have children was noted in 78% (329/422) of patients, of which 82.4% (271/329) were treated with antiretroviral drugs; this was significantly higher in subjects under 40 years versus those over 40 years old [81% (268/329) versus 19% (61/329), p<0.001]. Sero-discordant couples represented 33.4% (110/329) of patients. The frequency of patients with the desire to have a child was significantly higher when patients wanted to hold the status of parent of a child [77% (255/329) versus 23% (74/329), p<0.001]; this was influenced by the partner's desire [60% 197/329 versus 40% (132/329), p< 0.001], as well as by the absence of weight loss [56% (185/329) versus 44% (144/329), p<0.001]. The average number of children was significantly lower in patients with the desire to procreate compared to those with no desire to have children [1.7 versus 3.2, p<0.001]. These first observations in Gabon highlight the importance of the desire to have children in PLHIV and sero-discordant couples, and they show the level of interest in developing assistance methods for procreation and family planning programs to help this population, as well as to reduce the risk of mother-to-child HIV transmission.

When one can infect two: a reflection on the impact of HIV discordance on child HIV infection.

This is an opinion piece based on data and experience from Rwanda. The authors believe this opinion piece may help improve current programs on prevention of HIV transmission from mother to child in Africa taking into account the prevalence of HIV sero-discordance in couples. The authors recommend that if we want to ensure newborns stay HIV negative, PMTCT protocols should offer a series of HIV tests linked with antenatal visits and the lactation period as well as HIV testing of current sexual partners. Moreover, if the male partner is found to be positive and the woman is negative, programs should provide intensive counseling on the use of condoms. The lives of three individuals have the potential to be changed from HIV testing and counseling. Morally, this cannot be ignored.
