Cost-effectiveness of voluntary medical male circumcision for HIV prevention across sub-Saharan Africa: results from five independent models

BACKGROUND

Voluntary medical male circumcision (VMMC) has been a recommended HIV prevention strategy in sub-Saharan Africa since 2007, particularly in countries with high HIV prevalence. However, given the scale-up of antiretroviral therapy programmes, it is not clear whether VMMC still represents a cost-effective use of scarce HIV programme resources.

METHODS

Using five existing well described HIV mathematical models, we compared continuation of VMMC for 5 years in men aged 15 years and older to no further VMMC in South Africa, Malawi, and Zimbabwe and across a range of setting scenarios in sub-Saharan Africa. Outputs were based on a 50-year time horizon, VMMC cost was assumed to be US$90, and a cost-effectiveness threshold of US$500 was used.

FINDINGS

In South Africa and Malawi, the continuation of VMMC for 5 years resulted in cost savings and health benefits (infections and disability-adjusted life-years averted) according to all models. Of the two models modelling Zimbabwe, the continuation of VMMC for 5 years resulted in cost savings and health benefits by one model but was not as cost-effective according to the other model. Continuation of VMMC was cost-effective in 68% of setting scenarios across sub-Saharan Africa. VMMC was more likely to be cost-effective in modelled settings with higher HIV incidence; VMMC was cost-effective in 62% of settings with HIV incidence of less than 0·1 per 100 person-years in men aged 15-49 years, increasing to 95% with HIV incidence greater than 1·0 per 100 person-years.

INTERPRETATION

VMMC remains a cost-effective, often cost-saving, prevention intervention in sub-Saharan Africa for at least the next 5 years.

Voluntary Medical Male Circumcision to Reduce HIV Acquisition and Transmission

PURPOSE OF REVIEW

This commentary introduces the special Global Health Section on the state of voluntary medical male circumcision (VMMC) programs and current knowledge as to role of VMMC prevention of HIV infection acquisition in men and, indirectly, women.

RECENT FINDINGS

Since the first clinical trial of VMMC in Africa was published in 2005, implementation of programs has depended on illuminating best practices and key obstacles in the effort to expand VMMC in areas of high HIV prevalence to reduce HIV acquisition among men, with consequent benefits that uninfected men will not infect others. Global efforts are focused on sub-Saharan Africa, given the favorable expected impact of VMMC deployment where HIV incidence is high and circumcision rates are low. With estimated field effectiveness estimated to exceed 60%, reduced HIV risk for circumcised men in sub-Saharan Africa based on a once-only minor surgical intervention provides extraordinary preventive benefits. Where high VMMC rates have been achieved, declining HIV incidence rates may be partially or substantially attributed to VMMC, but this remains to be investigated. Articles in this special section address achievements, obstacles and risks, and plans for future progress in partnership with affected communities.

The Effects of Medical Male Circumcision on Female Partners' Sexual and Reproductive Health

PURPOSE OF REVIEW

Voluntary medical male circumcision (VMMC) reduces the risk of HIV acquisition by 60% among heterosexual men, provides protection against certain sexually transmitted infections (STI), and leads to penile microbiome composition changes associated with reduced risk of HIV infection. Intuitively, the benefits of VMMC for female sex partners in relation to STI are likely and have been evaluated. The purpose of this review is to examine emerging findings of broader sexual and reproductive health (SRH) benefits of VMMC for female sex partners.

RECENT FINDINGS

Systematic reviews find strong evidence for beneficial effects of VMMC on female sex partners risk of HPV, cervical dysplasia, cervical cancer, and with likely protection against trichomoniasis and certain genital ulcerative infections. Few studies assess the direct impact of VMMC on the vaginal microbiome (VMB), though several studies demonstrate reductions in BV, which is mediated by the VMB. Studies are lacking regarding male circumcision status and outcomes associated with non-optimal VMB, such as female infertility and adverse pregnancy outcomes. VMMC has positive effects on women's perceptions of sexual function and satisfaction, and perceptions of disease risk and hygiene, without evidence of risk compensation. VMMC has consistent association with a broad range of women's SRH outcomes, highlighting the biological and non-biological interdependencies within sexual relationships, and need for couples-level approaches to optimize SRH for men and women. The paucity of information on VMMC and influence on VMB is a barrier to optimizing VMB-associated SRH outcomes in female partners.

Effects of COVID-19 Pandemic on Voluntary Medical Male Circumcision Services for HIV Prevention, Sub-Saharan Africa, 2020

Beginning in March 2020, to reduce COVID-19 transmission, the US President's Emergency Plan for AIDS Relief supporting voluntary medical male circumcision (VMMC) services was delayed in 15 sub-Saharan African countries. We reviewed performance indicators to compare the number of VMMCs performed in 2020 with those performed in previous years. In all countries, the annual number of VMMCs performed decreased 32.5% (from 3,898,960 in 2019 to 2,631,951 in 2020). That reduction is largely attributed to national and local COVID-19 mitigation measures instituted by ministries of health. Overall, 66.7% of the VMMC global annual target was met in 2020, compared with 102.0% in 2019. Countries were not uniformly affected; South Africa achieved only 30.7% of its annual target in 2020, but Rwanda achieved 123.0%. Continued disruption to the VMMC program may lead to reduced circumcision coverage and potentially increased HIV-susceptible populations. Strategies for modifying VMMC services provide lessons for adapting healthcare systems during a global pandemic.

How Does Voluntary Medical Male Circumcision Reduce HIV Risk?

PURPOSE OF REVIEW

Voluntary medical male circumcision (VMMC) is a surgical procedure that reduces HIV acquisition risk by almost two-thirds. However, global implementation is lagging, in part due to VMMC hesitancy. A better understanding of the mechanism(s) by which this procedure protects against HIV may increase acceptance of VMMC as an HIV risk reduction approach among health care providers and their clients.

RECENT FINDINGS

HIV acquisition in the uncircumcised penis occurs preferentially across the inner foreskin tissues, due to increased susceptibility that is linked to elevated inflammatory cytokine levels in the sub-preputial space and an increased tissue density of HIV-susceptible CD4 + T cells. Inflammation can be caused by sexually transmitted infections, but is more commonly induced by specific anaerobic components of the penile microbiome. Circumcision protects by both directly removing the susceptible tissues of the inner foreskin, and by inducing a less inflammatory residual penile microbiome. VMMC reduces HIV susceptibility by removing susceptible penile tissues, and also through impacts on the penile immune and microbial milieu. Understanding these mechanisms may not only increase VMMC acceptability and reinvigorate global VMMC programs, but may also lead to non-surgical HIV prevention approaches focused on penile immunology and/or microbiota.

Circumcision Knowledge and Opinions of Primary Healthcare Workers: The Case of Turkey

This study evaluates the knowledge levels and opinions of Islamic primary healthcare workers regarding the medical indications of circumcision, its mode of application, contraindications, and possible complications together with the current literature. Our study was conducted with the participation of 400 healthcare personnel having Islamic faith and working in primary healthcare centers in Kahramanmaras. Data were collected through in-person interviews with healthcare workers who completed our questionnaire consisting of 52 questions and designed based on a literature review. SPSS 21 was used to evaluate the collected data statistically. Findings were considered statistically significant if the p-value was lower than 0.05. We evaluated these participants in terms of their levels of knowledge on circumcision. None of the participants had a very high knowledge level. In correlation analysis, it was detected that age (r = 0.194, p < 0.001) and duration of employment in the profession (experience) (r = 0.164, p = 0.001) were positively correlated with knowledge level. Those who found circumcision necessary mostly justified its necessity due to medical benefits (n = 321, 80.3%) and/or religious obligations (n = 242, 60.5%). Our study demonstrates the importance of providing information about circumcision, including the information from the current literature, to primary healthcare workers together with theoretical training and practice both during their formal training and after graduation in Turkey.

Does Voluntary Medical Male Circumcision Reduce HIV Risk in Men Who Have Sex with Men?

PURPOSE OF REVIEW

To review the evidence on the effect of voluntary medical male circumcision (VMMC) on reducing HIV risk among men who have sex with men (MSM) and assess the limitations of available evidence.

RECENT FINDINGS

Individual studies have shown conflicting results, but recent meta-analyses have consistently suggested that VMMC was associated with 7 to 23% reductions in HIV prevalence or incidence in MSM, particularly among a subgroup of men who predominantly practice insertive role in anal sex. Mathematical models have also suggested a moderate population-level impact of VMMC intervention. All original studies have been observational and are subject to confounding and bias. Randomized clinical trials (RCTs) are needed to provide strong evidence of assessing the efficacy of VMMC on HIV risk among MSM. VMMC is a promising HIV risk reduction tool for MSM. RCTs are needed to evaluate the efficacy of VMMC intervention.

Is Circumcision "Necessary" in Islam? A Philosophical Argument Based on Peer Disagreement

In recent years, there has been a resurgence in debates on the ethics of child genital cutting practices, both female and male, including within a Muslim context. Opponents of female genital cutting sometimes assert that the practice is not mentioned explicitly in the Qur'an as a way of implying that it does not have any religious standing within Islam. However, neither is male genital cutting mentioned explicitly in the Qur'an, and yet most people accept that it is a Muslim religious practice. Both practices, however, are mentioned in secondary sources of Islamic jurisprudence, with disagreement among religious authorities about the status or authenticity of some of these sources. This paper considers the religious status of both female and male genital cutting practices within Islam and employs a philosophical argument based on "peer disagreement" to ask whether either practice is necessary (i.e., religiously required) for a devout Muslim to endorse.

"Our [Yao people's] circumcision is of the 'brain' not of the 'penis'": factors behind the resistance to voluntary medical male circumcision among Yao people of Mangochi in Southern Malawi

Aim

Malawi officially launched Voluntary Male Medical Circumcision (VMMC) in 2012 after the 2007 joint WHO /UNAIDS recommendation that VMMC be a key HIV prevention strategy for Sub-Sahara African region. Malawi data, however, contradicted the findings of three randomized studies conducted in Uganda, Kenya and South Africa between 2005 and 2007. While randomized trials demonstrated that male circumcision could contribute to a 60% relative reduction of HIV acquisition by men through heterosexual intercourse, HIV prevalence in Malawi was highest in the Southern Region where 47% of males were traditionally circumcised yet Central Region had 15.4% and Northern Region, 6.3%. By December 2018, Malawi had only achieved 756, 780 surgeries constituting 31% against the target of 60% of eligible men. The low achievement was due to resistance to services even in traditionally circumcising Yao communities. This study sought views of Yao respondents in Mangochi district, in Southern Malawi, on VMMC.

Methods

156 participants were interviewed (103 males and 53 females): 15 FGDs (involving 86 males and 50 females); 17 IDIs (involving 14 males, 3 females); 3 Key KIIs (involving 3 males, 0 females). For this paper, the authors only analyzed FGDs, IDIs and KIIs. Quotes from FGDs were not significant.

Results

The study identified that VMMC: a) did not contribute to societal moral values; b) involved female circumcisers; c) threatened chiefs' political authority and economic gains; d) threatened continuity of jando; e) was impotent against witchcraft; f) provided by inefficient providers; g) resembled Yao circumcision; h) wrongly translated as 'm'dulidwe wa abambo.'

Conclusions

The key barrier to VMMC services in Yao communities of Mangochi was the mistrust between government and implementers on one hand and Yao communities on the other due to inadequate engagement prior to the rollout of services.

[Knot-free suture and frenulum positioning combined with application positioning using a disposable circumcision suture device in circumcision]

OBJECTIVE

To explore the effect of knot-free suture and frenulum positioning combined with application positioning (KFS-FP + AP) in circumcision using a disposable circumcision suture device.

METHODS

We retrospectively analyzed the clinical data on 160 cases of circumcision for phimosis or redundant prepuce by KFS-FP + AP (the observation group, n = 80) or by routine circumcision (the control group, n = 80) with a disposable circumcision suture device from February 2021 to December 2021. We recorded the operation time, incidence of frenulum breve, incidence of frenulum dislocation, and Visual Analog Scale (VAS) scores at 6 hours after surgery, and compared them between the two groups of patients.

RESULTS

The operation time was longer in the observation than in the control group (8.00 ［8.00, 9.00］ min vs 5.00 ［5.00, 5.00］ min), and the incidence rates of frenulum breve (0 vs 8.75%, P < 0.05) and frenulum dislocation (0 vs 7.5%, P < 0.05) significantly lower in the former than in the latter group. There were no statistically significant difference in the VAS scores between the observation and the control groups (2.60 ［2.00, 3.00］ vs 2.55 ［2.00, 3.00］, P > 0.05).

CONCLUSION

KFS-FP + AP with a disposable circumcision suture device is a safe and effective method of circumcision, with high satisfaction of the patients and worthy of clinical promotion.

Incidence of circumcision among insured adults in the United States

Purpose

Although circumcision is the most commonly performed surgery in males, less is known about the incidence and indications of adult circumcision. In this study, we aim to present the incidence of adult circumcision across the United States.

Methods

Using IBM MarketScan^® Commercial Database from 2015 to 2018, we obtained claims for circumcision in men between 18 and 64 years of age. We calculated the incidence of adult circumcision over the study period and across the United States. We also collected data on indications for surgery using International Classification of Diseases codes.

Results

We identified a total of 12,298 claims for adult circumcisions. The mean age was 39 (±12.9) years. The average incidence rates remained relatively constant from 98.1 per 100,000 person-years in 2015 to 98.2 per 100,000 person-years in 2018 (Δ+0.1%). The age-standardized incidence rates varied significantly across the United States (from 0 to 194.8 per 100,000 person-years) with South Dakota having the highest rate. The most common indications for adult circumcision were phimosis (52.5%), routine/ritual circumcision (28.7%), phimosis + balanitis/balanoposthitis (6.8%), balanitis (3.8%) and balanoposthitis (2.6%), and significantly varied by age groups.

Conclusion

This study suggested a wide geographic variation in rates of adult circumcision between states with highest incidences in the Northeast United States. Future studies can identify the underlying causes for the observed variations.

Male Circumcision and Genital Human Papillomavirus (HPV) Infection in Males and Their Female Sexual Partners: Findings From the HPV Infection and Transmission Among Couples Through Heterosexual Activity (HITCH) Cohort Study

BACKGROUND

Previous studies examining the association between male circumcision (MC) and human papillomavirus (HPV) infections have reported inconsistent results. We used data from the HPV Infection and Transmission Among Couples Through Heterosexual Activity (HITCH) cohort study to examine the association between MC and HPV infections in males and their female sexual partners.

METHODS

We enrolled monogamous couples in a longitudinal study between 2005 and 2011 in Montreal, Canada. We used logistic and Poisson regression models with propensity score adjustment to estimate odds ratios (ORs) and rate ratios for the association between MC and the prevalence, transmission, and clearance of HPV infections.

RESULTS

Four hundred thirteen couples were included in our study. The prevalence OR for the association between MC and baseline infections was 0.81 (95% confidence interval [CI], .56-1.16) in males and 1.05 (95% CI, .75-1.46) in females. The incidence rate ratio for infection transmission was 0.59 (95% CI, .16-2.20) for male-to-female transmission and 0.77 (95% CI, .37-1.60) for female-to-male transmission. The clearance rate ratio for clearance of infections was 0.81 (95% CI, .52-1.24).

CONCLUSIONS

We found little evidence of an association between MC and HPV infection prevalence, transmission, or clearance in males and females. Further longitudinal couple-based studies are required to investigate this association.

Voluntary medical male circumcision in selected provinces in South Africa: Outcomes from a programmatic setting

Introduction

Voluntary medical male circumcision (VMMC) remains an effective biomedical intervention for HIV prevention in high HIV prevalence countries. In South Africa, United States Agency for International Development VMMC partners provide technical assistance to the Department of Health, at national and provincial levels in support of the establishment of VMMC sites as well as in providing direct VMMC services at site level since April 2012. We describe the outcomes of the Right to Care (RTC) VMMC program implemented in South Africa from 2012 to 2017.

Methods

This retrospective study was undertaken at RTC supported facilities across six provinces. Young males aged ≥10 years who presented at these facilities from 1 July 2012 to 31 September 2017 were included. Outcomes were VMMC uptake, HIV testing uptake and rate of adverse events (AEs). Using a de-identified observational database of these clients, summary statistics of the demographic characteristics and outcomes were calculated.

Results

There were a total 1,001,226 attendees of which 998,213 (99.7%) were offered VMMC and had a median age of 15 years (IQR = 12–23 years). Of those offered VMMC, 99.6% (994,293) consented, 96.7% (965,370) were circumcised and the majority (46.3%) were from Gauteng province. HIV testing uptake was 71% with a refusal rate of 15%. Of the newly diagnosed HIV positives, 64% (6,371 / 9,972) referrals were made. The rate of AEs, defined as bleeding, infection, and insufficient skin removal) declined from 3.26% in 2012 to 1.17% in 2017. There was a reduction in infection-related AEs from 2,448 of the 2,602 adverse events (94.08%) in 2012 to 129 of the 2,069 adverse events (6.23%) in 2017.

Conclusion

There was a high VMMC uptake with a decline in AEs over time. Adolescent men contributed the most to the circumcised population, an indication that the young population accesses medical circumcision more. VMMC programs need to implement innovative demand creation strategies to encourage older males (20–34 years) at higher risk of HIV acquisition to get circumcised for immediate impact in reduction of HIV incidence. HIV prevalence in the total population increased with increasing age, notably in clients above 25 years.

Opinions on integrating couple counselling and female sexual reproductive health services into Voluntary Medical Male Circumcision services in Lilongwe, Malawi

Background

Couples HIV Counselling and Testing (CHCT) has been found to be potentially beneficial than individual HIV Counselling and Testing for prevention and treatment of HIV. However, there are few health care opportunities for men and women to access health services together, leading to underutilization of CHCT service. Integrating female Sexual and Reproductive Health (SRH) services into male-dominated service could be more effective than trying to integrate men’s health services into female-dominated health services. A potential site for male-female service integration could be Voluntary Medical Male Circumcision (VMMC) centers.

Methodology

We conducted a qualitative study in Lilongwe, Malawi between June to August 2018. Twenty VMMC clients, 20 peers and 20 VMMC providers completed individual in-depth interviews to share their opinions on what they thought about integrating CHCT and other SRH Services into VMMC services. These proposed SRH services include family planning, cervical cancer screening, sexually transmitted infection management and pre-exposure prophylaxis (PrEP). Content analysis was used to analyze the results.

Results

All participants were receptive to integration of CHCT, and most accepted the integration of SRH services into VMMC Services. Most VMMC clients, peers and care providers said that CHCT integration would help couples to know their HIV status, prevent HIV transmission, encourage healthy relationships, and provide a chance for women to participate in VMMC counselling and wound care. However, integration of other services, such as family planning and cervical cancer screening, drew mixed opinions among participants. Most VMMC clients, peers and providers felt that integration of services would promote male involvement and increase men’s knowledge in feminine sexual reproductive health services. A few providers expressed concerns over service integration, citing reasons such as overcrowding, work overload, gender mixing, and lack of provider capacity and space. Most participants supported integrating PrEP with VMMC Services and felt that PrEP would complement VMMC in HIV prevention. Few providers, peers and VMMC clients felt the addition of PrEP to VMMC services would lead to high-risk sexual activity that would then increase the risk for HIV acquisition. A few participants recommended community sensitization when integrating some of sexual reproductive health services into VMMC Services to mitigate negative perceptions about VMMC services and encourage service uptake among couples

Conclusion

Most participants service providers, VMMC clients and Peers were receptive to integrating SRH services, particularly HIV prevention services such as CHCT and PrEP, into male dominated VMMC services. Adequate community sensitization is required when introducing other SRH services into VMMC services.
