(Journal of the International AIDS Society, 2019) Nakku-Joloba, Edith; Pisarski, Emily E.; Wyatt, Monique A.; Muwonge, Timothy R.; Asiimwe, Stephen; Celum, Connie L.; Baeten, Jared M.; Katabira, Elly T.; Ware, Norma C.
Pre-exposure prophylaxis (PrEP) to prevent HIV infection is being rolled out in Africa. The uptake of PrEP to date has varied across populations and locations. We seek to understand the drivers of demand for PrEP through analysis of qualitative data collected in conjunction with a PrEP demonstration project involving East African HIV serodiscordant couples. Our goal was to inform demand creation by understanding what PrEP means – beyond HIV prevention – for the lives of users. Methods: The Partners Demonstration Project evaluated an integrated strategy of PrEP and antiretroviral therapy (ART) delivery in which time-limited PrEP served as a “bridge” to long-term ART. Uninfected partners in HIV serodiscordant couples were offered PrEP at baseline and encouraged to discontinue once infected partners had taken ART for six months. We conducted 274 open-ended interviews with 93 couples at two Ugandan research sites. Interviews took place one month after enrolment and at later points in the follow-up period. Topics included are as follows: (1) discovery of serodiscordance; (2) decisions to accept/decline PrEP and/or ART; (3) PrEP and ART initiation; (4) experiences of using PrEP and ART; (5) PrEP discontinuation; (6) impact of PrEP and ART on the partnered relationship. Interviews were audio-recorded and transcribed. We used an inductive, content analytic approach to characterize meanings of PrEP stemming from its effectiveness for HIV prevention. Relevant content was represented as descriptive categories. Results: Discovery of HIV serodiscordance resulted in fear of HIV transmission for couples, which led to loss of sexual intimacy in committed relationships, and to abandonment of plans for children. As a result, partners became alienated from each other. PrEP countered the threat to the relationship by reducing fear and reinstating hopes of having children together. Condom use worked against the re-establishment of intimacy and closeness. By increasing couples’ sense of protection against HIV infection and raising the prospect of a return to “live sex” (sex without condoms), PrEP was perceived by couples as solving the problem of serodiscordance and preserving committed relationships. Conclusions: The most effective demand creation strategies for PrEP may be those that address the everyday life priorities of potential users in addition to HIV prevention.
Effect of suppressive acyclovir administered to HSV-2 positive mothers from week 28 to 36 weeks of pregnancy on adverse obstetric outcomes: a double-blind randomized placebo-controlled trial
(Reproductive health, 2017) Nakubulwa, Sarah; Kaye, Dan K.; Bwanga, Freddie; Mbona Tumwesigye, Nazarius; Nakku-Joloba, Edith; Mirembe, Florence
Acyclovir (ACV) given to HSV-2 positive women after 36 weeks reduces adverse outcomes but its benefit at lower gestation was undocumented. We determined the effect of oral acyclovir administered from 28 to 36 weeks on premature rupture of membranes (PROM) primarily and preterm delivery risk. This was a randomized, double-blind placebo-controlled trial among 200 HSV-2 positive pregnant women at 28 weeks of gestation at Mulago Hospital, Uganda. Participants were assigned randomly (1:1) to take either acyclovir 400 mg orally twice daily (intervention) or placebo (control) from 28 to 36 weeks. Both arms received acyclovir after 36 weeks until delivery. Development of Pre-PROM by 36 weeks and preterm delivery were outcomes. One hundred women were randomized to acyclovir and 100 to placebo arms between January 2014 and February 2015. There was tendency towards reduction of incidence of PROM at 36 weeks but this was not statistically significant (4.0% versus 10.0%; RR 0.35; 95% 0.11–1.10) in the acyclovir and placebo arms respectively. However, there was a significant reduction in the incidence of preterm delivery (11.1% versus 23.5%; RR 0.41; 95% 0.20–0.85) in the acyclovir and placebo arms respectively. Oral acyclovir given to HSV-2 positive pregnant women from 28 to 36 weeks reduced incidence of preterm delivery but did not significantly reduce incidence of pre-PROM.
Incidence and risk factors for herpes simplex virus type 2 seroconversion among pregnant women in Uganda: A prospective study
(The Journal of Infection in Developing Countries, 2016) Nakubulwa, Sarah; Kaye, Dan K.; Bwanga, Freddie; Mbona Tumwesigye, Nazarius; Nakku-Joloba, Edith; Mirembe, Florence M.
Herpes simplex virus type 2 (HSV-2) acquired during pregnancy is associated with adverse outcomes such as perinatal HSV-2 transmission. HSV-2 seroconversion occurs within four weeks of HSV-2 acquisition. There was neither documented incidence nor risk factors for HSV-2 seroconversion during pregnancy in Uganda. The objective of this study was to determine the incidence and risk factors for HSV-2 seroconversion among pregnant women in Mulago Hospital, Uganda. Methodology: A prospective study of 200 consenting HSV-2-negative women between 26 and 28 weeks of gestation was done between November 2013 and October 2014. HSV-2 serostatus was determined using HerpeSelect HSV-2 enzyme-linked immunosorbent assay (ELISA). Interviewer-administered questionnaires were used to collect socio-demographic characteristics and sexual history. Human immunodeficiency virus (HIV) serostatus was obtained from antenatal records. A total of 191 women completed follow-up and repeat HSV-2 serology by 38 weeks. Negative binomial regression analysis was used to estimate risk ratios for risk factors for HSV-2 seroconversion. Results: Of 191 women, 15 (7.9%) seroconverted during pregnancy. Having multiple sexual partners, being in polygamous unions, and having HIV-positive serostatus were found to be risk factors for HSV-2 seroconversion. Conclusions: The incidence of HSV-2 seroconversion during pregnancy in Uganda was high. Multiple sexual partners, polygamy, and HIV-positive serostatus were risk factors for HSV-2 seroconversion during pregnancy. Strengthening health education on the avoidance of multiple sexual partners during pregnancy is paramount in prevention of HSV-2 seroconversion.
Integrated delivery of antiretroviral treatment and pre-exposure prophylaxis to HIV-1 serodiscordant couples in East Africa: a qualitative evaluation study in Uganda
(Journal of the International AIDS Society, 2018) Ware, Norma C.; Pisarski, Emily E.; Nakku-Joloba, Edith; Wyatt, Monique A.; Muwonge, Timothy R.; Turyameeba, Bosco; Asiimwe, Stephen B.; Heffron, Renee A.; Baeten, Jared M.; Celum, Connie L.; Katabira, Elly T.
Serodiscordant couples are a priority population for delivery of new HIV prevention interventions in Africa. An integrated strategy of delivering time-limited, oral pre-exposure prophylaxis (PrEP) to uninfected partners in serodiscordant couples as a bridge to long-term antiretroviral treatment (ART) for infected partners has been implemented in East Africa, nearly eliminating new infections. We conducted a qualitative evaluation of the integrated strategy in Uganda, to better understand its success. Methods: Data collection consisted of 274 in-depth interviews with 93 participating couples, and 55 observations of clinical encounters between couples and healthcare providers. An inductive content analytic approach aimed at understanding and interpreting couples’ experiences of the integrated strategy was used to examine the data. Analysis sought to characterize: (1) key aspects of services provided; (2) what the services meant to recipients; and (3) how couples managed the integrated strategy. Themes were identified in each domain, and represented as descriptive categories. Categories were grouped inductively into more general propositions based on shared content. Propositions were linked and interpreted to explain “why the integrated strategy worked.” Results: Couples found “couples-focused” services provided through the integrated strategy strengthened partnered relationships threatened by the discovery of serodiscordance. They saw in services hope for “getting help” to stay together, turned joint visits to clinic into opportunities for mutual support, and experienced counselling as bringing them closer together. Couples adopted a “couples orientation” to the integrated strategy, considering the health of partners as they made decisions about initiating ART or accepting PrEP, and devising joint approaches to adherence. A couples orientation to services, grounded in strengthened partnerships, may have translated to greater success in using antiretrovirals to prevent HIV transmission. Conclusions: Various strategies for delivering antiretrovirals for HIV prevention are being evaluated. Understanding how and why these strategies work will improve evaluation processes and strengthen implementation platforms. We highlight the role of service organization in shaping couples’ experiences of and responses to ART and PrEP in the context of the integrated strategy. Organizing services to promote positive care experiences will strengthen delivery and contribute to positive outcomes as antiretrovirals for prevention are rolled out.

(Science translational medicine, 2021) Trick, Alexander Y.; Melendez, Johan H.; Onzia, Annet; Zawedde, Aidah; Nakku-Joloba, Edith; Kyambadde, Peter; Mande, Emmanuel; Matovu, Joshua; Atuheirwe, Maxine; Kwizera, Richard
Effective treatment of sexually transmitted infections (STIs) is limited by diagnostics that cannot deliver results rapidly while the patient is still in the clinic. The gold standard methods for identification of STIs are nucleic acid amplification tests (NAATs), which are too expensive for widespread use and have lengthy turnaround times. To address the need for fast and affordable diagnostics, we have developed a portable, rapid, on-cartridge magnetofluidic purification and testing (PROMPT) polymerase chain reaction (PCR) test. We show that it can detect Neisseria gonorrhoeae, the pathogen causing gonorrhea, with simultaneous genotyping of the pathogen for resistance to the antimicrobial drug ciprofloxacin in <15 min. The duplex test was integrated into a low-cost thermoplastic cartridge with automated processing of penile swab samples from patients using magnetic beads. A compact instrument conducted DNA extraction, PCR, and analysis of results while relaying data to the user via a smartphone app. This platform was tested on penile swab samples from sexual health clinics in Baltimore, MD, USA (n = 66) and Kampala, Uganda (n = 151) with an overall sensitivity and specificity of 97.7% (95% CI, 94.7 to 100%) and 97.6% (95% CI, 94.1 to 100%), respectively, for N. gonorrhoeae detection and 100% concordance with culture results for ciprofloxacin resistance. This study paves the way for delivering accessible PCR diagnostics for rapidly detecting STIs at the point of care, helping to guide treatment decisions and combat the rise of antimicrobial resistant pathogens.

(African health sciences, 2014) Nakku-Joloba, Edith; Kambugu, Fred; Wasubire, Julius; Kimeze, Joshua; Salata, Robert; Albert, Jeffrey M.; Rimm, Alfred; Whalen, Christopher
Prevalence of herpes simplex type 2 virus (HSV-2) is high worldwide. Previous studies in Uganda were rural or in women. We estimated age and sex-specific sero- prevalence of HSV-2 in Kampala, Uganda.Using two-stage random sampling stratified on population density, a survey of persons 15-65 years was conducted. Type-specific serological tests for HSV-2, HSV-1(HerpeSelect2 and 1 ELISA), HIV (Rapid tests and ELISA), syphilis (RPR and TPHA) were done. Additional prevalence analysis included post-stratification weighting on the Uganda 2002 Census gender distribution.Among 1124 persons, HSV-2 prevalence was 58% (95% CI: 55, 60), HSV-1; 98% (95% CI: 97.6, 99.1), HIV; 17.7% (95% CI: 14.8, 19.2) and syphilis; 1.7% (95% CI: 1.4, 1.9). Weighted HSV-2 prevalence was 53.8% (Women; 63.8%, men; 43.2%), similar to unweighted data. Weighted HIV prevalence was 20.7% in women, 8.6% in men. Of 165 HIV infected persons, 85.4% had HSV-2. Risk factors for HSV-2 were being a woman (OR 2.0; 95% CI: 1.42, 2.78), age (OR 3.3; 95% CI: 2.43, 4.53), education (OR 1.70; 95% CI: 1.34, 2.34) and HIV (OR 4.5; 95% CI: 2.70, 7.50).Prevalence of HSV-2 and HIV was high especially in women. Syphilis was rare. Awareness of herpes was low. Interventions in young people are needed.
Users May Lack Confidence in ART for HIV Prevention: A Qualitative Analysis
(Conference on retroviruses and opportunistic infections (CROI), 2017) Wyatt, Monique A.; Pisarski, Emily E.; Baeten, Jared M.; Heffron, Renee; Nakku-Joloba, Edith; Muwonge, Timothy R.; Katabira, Elly T.; Celum, Connie L.; Ware, Norma C.
Antiretroviral-based approaches to HIV prevention have been shown to reduce new infections in clinical trials and demonstration settings. To optimize uptake and anticipate barriers to effective rollout, we must understand users’ perspectives on antiretroviral treatment (ART) for prevention of HIV transmission. We explored serodiscordant couples’ understandings of and feelings about treatment as prevention using qualitative data from the Partners Demonstration Project. The Partners Demonstration Project employed an integrated delivery strategy of daily oral pre-exposure prophylaxis (PrEP) and ART for serodiscordant couples in Kenya and Uganda. PrEP use was time-limited and discontinued after HIVinfected partners had been on ART for 6 months. Multiple in-depth qualitative interviews were conducted with a subset of 48 couples from the Kampala, Uganda Partners Demonstration Project site (N interviews=195). Interview topics included: (a) perceived purpose and meanings of PrEP and ART; (b) adherence; (c) experiences of PrEP discontinuation; and (d) understandings of antiretroviral treatment as prevention. Interviews were audio-recorded, transcribed into English and coded using Atlas.ti software by two trained analysts. Coded data were inductively analyzed to identify themes representing couples’ understandings of and feelings about using ART for prevention of HIV transmission. Categories were developed to represent the themes.
