Acceptability, feasibility and appropriateness of intensified health education, SMS/phone tracing and transport reimbursement for uptake of voluntary medical male circumcision in a sexually transmitted infections clinic in Malawi: a mixed methods study.

Introduction: Uptake of voluntary medical male circumcision (VMMC) remains a challenge in many settings. Innovative implementation strategies are required to scale-up VMMC uptake. Methodology: RITe was a multi-faceted intervention comprising transport reimbursement (R), intensified health education (IHE) and SMS/Telephone tracing (Te), which increased the uptake of VMMC among uncircumcised men with sexually transmitted infections (STIs) in Malawi. Using a concurrent exploratory mixed-method approach, we assessed the intervention's acceptability, feasibility and appropriateness among men with STIs and healthcare workers (HCWs) at Bwaila District Hospital. Participants completed Likert scale surveys and participated in-depth interviews (IDIs) and focus group discussions (FGDs). We calculated percentages of responses to survey items and summarized common themes using thematic analysis. Median scores and interquartile ranges (IQR) were calculated for acceptability, feasibility and appropriateness of each strategy at baseline and end-line and compared using the Wilcoxon signed rank test. Results: A total of 300 surveys, 17 IDIs and 4 FGDs were conducted with men and HCWs between baseline and end-line. The mean age for men in the survey was 29 years (SD ±8) and most were married/cohabiting (59.3%). Mean age for HCWs was 38.5 years (SD ±7), and most were female (59.1%). For acceptability, participants agreed that RITe was welcome, approvable, and likable. Despite participants agreeing that RITe was a good idea, culture and religion influenced appropriateness, particularly at baseline, which improved at end-line for Te and R. For feasibility, HCWs agreed that RITe was easy to implement, but expressed concerns that R (end-line median = 4, IQR: 2, 4) and Te (end-line median = 4, IQR: 4, 4), were resource intensive, hence unsustainable. Interviews corroborated the survey results. Participants reported that IHE provided important information, Te was a good reminder and R was attractive, but they reported barriers to R and Te such as electricity, limited access to phones and distrust in the government. Conclusions: The RITe intervention was acceptable, feasible and appropriate. However, culture/religion and structural barriers affected perceptions of appropriateness and feasibility, respectively. Continued awareness raising on VMMC and addressing setting-specific structural factors are required to overcome barriers that impede demand-creation interventions for VMMC.

Effectiveness of an intervention to increase uptake of voluntary medical male circumcision among men with sexually transmitted infections in Malawi: a preinterventional and postinterventional study.

OBJECTIVE: To evaluate the effect a multistrategy demand-creation and linkage intervention on voluntary medical male circumcision (VMMC) uptake, time to VMMC and predictors of VMMC uptake among men with sexually transmitted infections (STIs). DESIGN: Pragmatic preinterventional and postinterventional quasi-experimental study combined with a prospective observational design. SETTING: A public and specialised STI clinic in Lilongwe, Malawi. POPULATION: Uncircumcised men who presented to the STI clinic. METHODS AND INTERVENTION: The intervention consisted of transport reimbursement ('R'), intensified health education ('I') and short-messaging services/telephonic tracing ('Te'), abbreviated (RITe). A preintervention phase was conducted at baseline while RITe was rolled-out in the intervention phase in a sequential manner called implementation blocks: 'I' only-block 1; 'I+Te'-block 2 and RITe-block 3. MAIN OUTCOME MEASURES: Primary: VMMC uptake and time to VMMC for the full intervention and for each block. Secondary: predictors of VMMC uptake. RESULTS: A total of 2230 uncircumcised men presented to the STI clinic. The mean age was 29 years (SD±9), 58% were married/cohabiting, HIV prevalence was 6.4% and 43% had urethral discharge. Compared with standard of care (8/514, 1.6%), uptake increased by 100% during the intervention period (55/1716, 3.2%) (p=0.048). 'I' (25/731, 113%, p=0.044) and RITe (17/477, 125%, p=0.044) significantly increased VMMC uptake. The median time to VMMC was shorter during the intervention period (6 days, IQR: 0, 13) compared with standard of care (15 days, IQR: 9, 18). There was no significant incremental effect on VMMC uptake and time to VMMC between blocks. Men with genital warts were 18 times more likely to receive VMMC (adjusted relative risk=18.74, 95% CI: 2.041 to 172.453). CONCLUSIONS: Our intervention addressing barriers to VMMC improved VMMC uptake and time to VMMC among uncircumcised men with STIs, an important subpopulation for VMMC prioritisation.

Dramatic Shift in the Etiology of Genital Ulcer Disease Among Patients Visiting a Sexually Transmitted Infections Clinic in Lilongwe, Malawi.

BACKGROUND: Genital ulcer diseases (GUDs) are a common syndrome associated with sexually transmitted infections. Genital ulcer diseases increase the risk of HIV transmission, necessitating appropriate diagnosis and treatment. We provide an updated GUD etiology assessment in Malawi to guide diagnostic development and treatment algorithms. METHODS: We enrolled patients 18 years or older presenting with GUD at a sexually transmitted infection clinic in Lilongwe, Malawi, between May and October 2021. We purposively sampled by HIV status. Swabs of ulcers were tested for Treponema pallidum, herpes simplex virus (HSV)-1 and HSV-2, Haemophilus ducreyi, and Chlamydia trachomatis using polymerase chain reaction. Blood was collected for syphilis and HSV-2 serologies and acute HIV testing. Participants were treated per Malawi guidelines. Ulcer resolution (size reduced by >50%) was evaluated 14 days later. RESULTS: Fifty participants enrolled (30 without HIV, 2 with acute HIV infection, 18 with HIV seropositivity; 32 men, 18 women). Forty-six (92%) had an etiology identified. Syphilis was more common among those without HIV (22 of 30 [73%]) than participants with HIV (PWH; 8 of 20 [40%]; P = 0.04). Herpes simplex virus was more common among PWH (11 of 20 [55%]) than participants without (2 of 30 [7%]; P = 0.0002). One-fifth (9 of 50 [18%]) had H. ducreyi. Among those who returned for follow-up (n = 45), 9 (20%) had unresolved ulcers; persistent GUD was slightly more common in PWH (6 of 19 [32%]) than participants without (3 of 26 [12%]; P = 0.14). CONCLUSIONS: We observed a dramatic increase in syphilis ulcer proportion in a population whose GUDs were previously HSV predominant. Observed differences in etiology and resolution by HIV status could play an important role in the ongoing transmission and treatment evaluation of GUD.

HIV and urethritis: time required for antiretroviral therapy to suppress HIV in semen.

OBJECTIVES: To examine the time required to suppress HIV in the genital tract with antiretroviral therapy (ART) in men with urethritis. DESIGN: An observational cohort study. METHODS: Men with HIV and urethritis not on ART were enrolled at an STI clinic in Malawi and offered to initiate ART. Blood and semen samples were collected pretreatment and at 1, 2, 4, 8, 12 and 24 weeks posturethritis treatment. Median viral loads (VLs) were calculated by ART initiation groups: 'within 1 week', 'between 1 and 4 weeks' and 'no ART before 4 weeks', based on the men's choice about whether or not to initiate ART. The presence of ART at each visit was confirmed by bioanalytical methods. FINDINGS: Between January 2017 and November 2018, 74 men presented with urethritis and HIV and were confirmed ART naive. The median age was 32 years. Forty-one (55% of men) initiated ART within 1 week; 12 (16%) between 1 and 4 weeks; and 21 (28%) did not initiate ART by week 4. Within the 1 week group, median VL was suppressed within 4 weeks in both semen and blood. Among the 1-4 weeks group, VL was suppressed within 4 weeks in semen and 5 weeks in blood. Among the no ART before 4 weeks group, VL in semen declined within the first 4 weeks but remained unsuppressed through week 24, and there was no significant decline in blood HIV. CONCLUSION: Treatment of urethritis and prompt initiation of ART with counseling for safer sex for at least one month is a critical measure to reduce transmission of HIV.

Depression, Alcohol Use, and Sexual Behaviors by HIV Infection Stage and Diagnosis Timing Among STI Clinic Patients in Lilongwe, Malawi.

Understanding depression, alcohol use, and sexual behaviors according to HIV infection stage and diagnosis timing is important for HIV prevention efforts. We enrolled persons with recent infection and diagnosis (i.e., acute HIV infection (AHI) (n = 92) persons newly diagnosed seropositive (n = 360)) and persons previously diagnosed with HIV (n = 190) into a randomized controlled trial in Lilongwe, Malawi (N = 641) and estimated the prevalence of probable depression (Patient Health Questionnaire-9 ≥ 5), hazardous alcohol use (Alcohol Use Disorder Identification Test-C: men ≥ 4; women ≥ 3), and sexual behaviors (transactional sex, condomless sex). Compared with previously diagnosed participants, participants newly seropositive and those with AHI reported a higher proportion of probable depression (7%, 27%, 38%; AHI/Previous: Table Probability: 0.02, p < 0.01; AHI/New: Table Probability: <0.01, p < 0.01), hazardous alcohol use (8%, 18%, 29%; AHI/Previous and AHI/New: Table Probability: <0.01, p < 0.01), and transactional sex (5%, 14%, 20%; AHI/Previous: Table Probability: <0.01, p < 0.01; AHI/New: Table Probability: 0.06, p = 0.24), respectively. HIV prevention services addressing mental health and alcohol misuse may be particularly beneficial for persons with recent HIV infection and or diagnosis.

Integrating Enhanced HIV Pre-exposure Prophylaxis Into a Sexually Transmitted Infection Clinic in Lilongwe: Protocol for a Prospective Cohort Study.

BACKGROUND: Pre-exposure prophylaxis (PrEP) reduces HIV acquisition risk by >90% and is a critical lever to reduce HIV incidence. Identifying individuals most likely to benefit from PrEP and retaining them on PrEP throughout HIV risk is critical to realize PrEP's prevention potential. Individuals with sexually transmitted infections (STIs) are an obvious priority PrEP population, but there are no data from sub-Saharan Africa (SSA) confirming the effectiveness of integrating PrEP into STI clinics. Assisted partner notification may further enhance STI clinic-based PrEP programming by recruiting PrEP users from the pool of named sexual partners of individuals presenting with an incident STI. However, the acceptability, feasibility, and effectiveness of these integrated and enhanced strategies are unknown. OBJECTIVE: This study aims to describe the implementation outcomes of acceptability, feasibility, and effectiveness (regarding PrEP uptake and persistence) of integrating an enhanced PrEP implementation strategy into an STI clinic in Malawi. METHODS: The enhanced PrEP STI study is a prospective cohort study enrolling patients who are eligible for PrEP (aged ≥15 years) who are seeking STI services at a Lilongwe-based STI clinic. Data collection relies on a combination of in-depth interviews, patient and clinic staff surveys, and clinic record review. All enrolled PrEP users will be screened for acute HIV infection and receive quarterly testing for Neisseria gonorrhea, Chlamydia trachomatis, and syphilis. Participants will be asked to name recent sexual partners for assisted notification; returning partners will be screened for PrEP eligibility and, if interested, enrolled into the cohort of PrEP initiators. We will also enroll patients who are eligible for PrEP but choose not to initiate it, from the STI clinic. Patient participants will be followed for 6 months; we will assess self-reported PrEP use, PrEP refills, sexual behaviors, perceived HIV risk, and incident STIs. Clinic staff participants will be interviewed at baseline and at approximately 6 months and will complete surveys examining the perceived acceptability and feasibility of the integrated and enhanced PrEP strategy. RESULTS: Enrollment began in March 2022 and is projected to continue until February 2023, with patient participant follow-up through August 2023. The results of this study are expected to be reported in 2024. CONCLUSIONS: This study will generate important evidence regarding the potential integration of PrEP services into STI clinics in SSA and preliminary data regarding the effectiveness of an enhanced intervention that includes assisted partner notification as a strategy to identify potential PrEP users. Furthermore, this trial will provide some of the first insights into STI incidence among PrEP users recruited from an STI clinic in SSA-critical data to inform the use of etiologic STI testing where syndromic management is the current standard. These findings will help to design future PrEP implementation strategies in SSA. TRIAL REGISTRATION: ClinicalTrials.gov NCT05307991; https://clinicaltrials.gov/ct2/show/NCT05307991.

Gentamicin Susceptibility in Neisseria gonorrhoeae and Treatment Outcomes for Urogenital Gonorrhea After 25 Years of Sustained Gentamicin Use in Malawi.

BACKGROUND: Gentamicin has been used for the treatment of gonorrhea in Malawi since 1993. However, declining clinical cure rates have been suspected. We evaluated current Neisseria gonorrhoeae susceptibility to gentamicin in vitro and clinically. METHODS: Men with acute urethritis were recruited at the Bwaila District Hospital STI Clinic in Lilongwe, Malawi, between January 2017 and August 2019. All men provided urethral swabs for etiological testing at enrollment and test of cure (TOC), 1 week later, using Gram-stained microscopy and culture. We used Etest to determine minimum inhibitory concentrations (MICs) of gentamicin, azithromycin, cefixime, ceftriaxone, ciprofloxacin, and spectinomycin; disc diffusion for tetracycline susceptibility; and whole-genome sequencing (WGS) to verify/refute treatment failure. RESULTS: Among 183 N. gonorrhoeae culture-positive men enrolled, 151 (82.5%) had a swab taken for TOC. Of these 151 men, 16 (10.6%) had a positive culture at TOC. One hundred forty-one baseline isolates were tested for gentamicin susceptibility using Etest: 2 (1.4%), MIC = 2 µg/mL; 111 (78.7%), MIC = 4 µg/mL; and 28 (19.9%), MIC = 8 µg/mL. All isolates were susceptible to azithromycin, cefixime, ceftriaxone, and spectinomycin, whereas 63.1% had intermediate susceptibility or resistance to ciprofloxacin. Almost all (96.1%) isolates were resistant to tetracycline. All examined isolates cultured at TOC (n = 13) had gentamicin MICs ≤8 µg/mL. Ten men had pretreatment and posttreatment isolates examined by whole-genome sequencing; 2 (20%) were verified new infections (4119 and 1272 single-nucleotide polymorphisms), whereas 8 (80%) were confirmed treatment failures (0-1 single-nucleotide polymorphism). CONCLUSIONS: Gentamicin MICs poorly predict gonorrhea treatment outcome with gentamicin, and treatment failures are verified with gonococcal strains with in vitro susceptibility to gentamicin. The first-line treatment of gonorrhea in Malawi should be reassessed.

Syndromes Associated with Sexually Transmitted Infections in Lilongwe, Malawi: Burden and Trends, 2006 to 2015.

ABSTRACT: Monitoring the burden of and trends in sexually transmitted infection syndromes is useful in informing syndromic management guidelines. Among sexually transmitted infection clinic patients in Lilongwe, Malawi, between 2006 and 2015, genital discharge, lower abdominal pain, and genital ulcer syndromes were common. Prevalence of most syndromes remained stable during the 10-year period.

Effects of Urethritis on Human Immunodeficiency Virus (HIV) in Semen: Implications for HIV Prevention and Cure.

BACKGROUND: Prior to the widespread availability of antiretroviral therapy (ART), men living with human immunodeficiency virus (HIV) with urethritis had increased concentrations of HIV in semen. This study aims to better evaluate HIV shedding in men with urethritis receiving ART, and its implications for the cure of HIV. METHODS: Men living with HIV with urethritis taking ART ≥12 weeks were enrolled at a sexually transmitted infections clinic in Lilongwe, Malawi. Study follow-up included visits at 1, 2, 4, 8, 12, 24, 36, and 48 weeks after urethritis diagnosis and treatment. Matched blood and semen samples were collected at all visits, and all additional episodes of urethritis were followed with extra visits 1, 2, and 4 weeks after treatment. RESULTS: There were 111 men enrolled in the study between January 2017-March 2019, and 77 (69%) were suppressed in the blood (<400 copies/mL). Among the 77 men, 87 episodes of urethritis were evaluated during follow-up. Of the 87 episodes, 15 episodes (17%) had instances of seminal viral shedding ≥400 copies/mL despite viral suppression in the blood. During nonurethritis follow-up, ≤6% of men at each visit had a viral load ≥400 copies/mL in the semen while maintaining viral suppression in the blood. CONCLUSIONS: An HIV cure requires the elimination of HIV from every body compartment, but available ART does not currently accomplish this. Our study highlights the male genital tract as a local source of HIV that can be reversibly activated. A better understanding of this phenomenon is important to advance the HIV cure field.
