Getting to Zero: Safer Conception Programming Among HIV Sero-different Couples in Uganda

The Healthy Families safer conception program, based at the ISS Clinic at Mbarara Regional Referral Hospital (MRRH), offers client-centered care to help HIV-affected individuals and couples meet reproductive goals. This care supports clients to leverage personal motivations and partner and social supports to overcome structural barriers and use ART, adopt other HIV-prevention strategies, and remain in care. This pilot study (the 'Getting to Zero' study) will assess uptake and experiences of safer conception care among men living with HIV and their HIV sero-different partners, and will assess retention in care and HIV transmission risk to partners and infants.

There are six linked objectives in this study:

• To assess uptake of safer conception strategies among men living with HIV and/or their female partners overall, and by specific HIV prevention strategies.

Hypothesis 1: Investigators hypothesize that offering comprehensive safer conception services within HIV care will increase uptake of HIV prevention strategies among both male and female HIV-affected participants (including ART initiation, adherence, and HIV-RNA viral suppression in the partner living with HIV, HIV-serostatus disclosure, knowledge of partner's HIV-serostatus, Sexually Transmitted Infections (STI) testing and treatment, sexual behaviour (i.e., delaying condomless sex until HIV-infected partner is virally suppressed), and partner HIV testing and ARV use (PrEP or ART).

• Among men living with HIV and their partners, to assess socio-demographic, relationship, structural, and clinical factors associated with uptake of safer conception strategies.

Hypothesis 2: Investigators hypothesize that uptake will be associated with more equitable relationship power and dynamics, lower HIV-related stigma, higher social support, and other socio-structural determinants of health.

• To assess retention in HIV care among men living with HIV engaged in the safer conception intervention.

Hypothesis 3: Investigators hypothesize that men living with HIV who are engaged in the safer conception intervention will be better retained in HIV care over nine months relative to men receiving care at the ISS clinic, but who are not enrolled in the safer conception program.

• To assess periconception HIV transmission incidence among HIV-affected individuals and couples where the male partner is living with HIV and engaged in the safer conception intervention;

Hypothesis 4: Among HIV-affected individuals and couples successfully engaged in the safer conception intervention, investigators hypothesize no (within-couple) cases of periconception-related HIV transmission.

• To assess pregnancy and HIV incidence and outcomes among female partners of men living with HIV engaged in the intervention.

Hypothesis 5: Of pregnancies ending in live birth, investigators hypothesize <2% incidence of perinatal HIV transmission among infants born to couples successfully engaged in the intervention.

• To explore the acceptability and barriers/facilitators of the safer conception intervention among a sub-set of men living with HIV and their HIV sero-different partners.

Hypothesis 6: This is qualitative objective without pre-specified hypotheses.

This study will be conducted at the ISS Clinic in the Mbarara Regional Referral Hospital (MRRH) in Mbarara, Uganda.

This mixed-methods prospective pilot research study includes electronic chart review data, longitudinal survey data (from the male index and female partner participant), and qualitative data from in-depth semi-structured interviews. All of the study efforts will be conducted via the Immune Suppression Syndrome (ISS) Clinic in the Mbarara Regional Referral Hospital in Mbarara, Uganda. The ISS clinic is an IeDEA networks site with a high-quality clinical database. In December 2016, the ISS clinic initiated a safer conception program called the Healthy Families program, which provides counselling and clinical care for HIV-affected individuals and couples who desire pregnancy.

The target population for the Getting to Zero study is men living with HIV with HIV sero-different partners (defined as partners who are HIV-negative or HIV status unknown), who report personal and/or partner pregnancy desire in the next year. Participants will be recruited via information sessions held at the Healthy Families program as well as at the ISS Clinic, MRRH HIV counselling and testing sites, referrals from regional healthcare providers, and via community outreach efforts.

This pilot study aimed at demonstrating proof-of-concept aims to enroll 50 index participants and all female partners. Investigators anticipate, however, enrolling 25 female partners.

The target population for the Getting to Zero study is men living with HIV with HIV sero-different partners (defined as partners who are HIV-negative or HIV status unknown), who report personal and/or partner pregnancy desire in the next year. Participants will be recruited via information sessions held at the Healthy Families program as well as at the ISS Clinic, MRRH HIV counselling and testing sites, referrals from regional healthcare providers, and via community outreach efforts. After providing informed consent, participants will be asked to complete an interviewer-administered questionnaire detailing use of HIV prevention strategies as well as socio-demographic information, partnership dynamics, pregnancy intentions and desires, sexual and reproductive behaviours and history, HIV medical history, mental health, experiences of violence, HIV-related stigma, and social support.

Following the questionnaire, the participant (and his partner if she is present) will be offered safer conception services at the Healthy Families clinic, which includes an up to 30-minute counseling session. Counseling sessions incorporate education and some problem-solving support to help individuals and couples adopt safer conception strategies including HIV-serostatus disclosure to partner, ART uptake and adherence and HIV-RNA suppression, STI testing and treatment, timing condomless sex to peak fertility, partner ARV use (ART if living with HIV, PrEP if HIV negative), and contraception until ready to conceive. In addition, (1) all female partners are offered beta hcg pregnancy testing; (2) all HIV-negative participants are offered HIV counselling and testing; (3) all participants will complete testing for STIs (Neisseria gonorrhoeae, Chlamydia trachomatis, and Trichomonas vaginalis) via GeneXpert. Index participants will also complete testing for syphilis using Bioline testing (treponeme specific) followed by RPR confirmatory testing (non-treponeme specific); and (4) all participants living with HIV will also complete laboratory testing to assess HIV-RNA suppression.

Participants will be offered the safer conception counselling and clinical services at enrollment, 3-months (3M), and 6-months (6M), with two exceptions. First, STI testing will only be offered at the baseline visit for male participants only and subsequent follow-up visits will employ syndromic STI management, which is standard of care at the Healthy Families program. Second, participants will complete HIV-RNA suppression testing at enrolment and 6M.

Male participants will be asked for their consent for the study team to contact their female partners to assess eligibility, interest, and willingness to participate in the study. If he consents for the study team to contact his partner, he will be given an information letter to give to her describing the study purpose and procedures. Once consented, partners will be invited to safe conception counselling sessions as well as to participate in an individual in-depth interview to explore acceptability and barriers/facilitators of the Healthy Families program.

At enrollment and all Healthy Families program follow-up visits (3M and 6M):

• all female partners will be offered pregnancy testing via urine beta hcg testing. Results will be available within 3-5 minutes of testing. Women who test positive for pregnancy will be referred to appropriate antenatal care.
• all participants who are not known to be HIV-positive will be offered HIV counselling and testing. Individuals confirmed HIV-positive will receive post-test counselling and be referred for appropriate HIV care.
• all male participants will undergo objective STI testing at enrollment with same-day pathogen-specific treatment provided for the tested individual as well as to partners. Testing for Neisseria gonorrhoeae, Chlamydia trachomatis, and Trichomonas vaginalis will be done via GeneXpert. Participants will also complete testing for syphilis using Bioline testing (treponeme specific) followed by RPR confirmatory testing (non-treponeme specific). Symptomatic male patients will be treated as per national STI syndromic management guidelines. Male participants will be given the same course of treatment to take home to their female partners.
• all participants living with HIV will also complete laboratory testing to assess HIV-RNA suppression at baseline and 6M.

The procedures described are consistent with usual clinical management of HIV-affected individuals/couples receiving care at the Healthy Families Clinic (i.e., are part of usual clinical management).
