A Randomized Trial of Mogen Clamp Versus Plastibell for Neonatal Male Circumcision in Botswana

Abstract

Background Male circumcision can reduce the risk of heterosexually-acquired HIV-1 infection in men. Neonatal male circumcision (NMC) has many potential advantages over circumcision at older ages but little is known about its feasibility and safety in resource-limited settings. Methods We performed a randomized trial in southeastern Botswana of Mogen clamp and Plastibell, two commonly used devices for NMC. Follow-up visits occurred at six weeks and four months postpartum. Adverse events, parental satisfaction and staff impressions were recorded. Results Of 302 male neonates randomized, 300 (99%) underwent circumcision, 153 (51%) with Mogen clamp and 147 (49%) with Plastibell. There were no major adverse events in the Mogen clamp arm but there were two major adverse events in the Plastibell arm (both were a proximally migrated ring that had to be removed by study staff). Minor adverse events were more common with the Mogen clamp compared with the Plastibell, specifically removal of too little skin and formation of skin bridges or adhesions (12 vs. 1 and 11 vs. 3, respectively, all P<0.05). Five (3%) infants in the Mogen clamp arm and none in the Plastibell arm had minor bleeding (P=0.03). More than 94% of mothers reported being highly or completely satisfied with the procedure. Conclusions NMC can be performed in Botswana with a low rate of adverse events and high parental satisfaction. Although the risk of migration and retention of the Plastibell is small, the Mogen clamp may be safer for NMC in regions where immediate emergent medical attention is not available.

Determinants of morbidity associated with infant male circumcision: community‐level population‐based study in rural Ghana

“…However, our morbidity risk was lower than the three published African studies conducted in large urban hospitals in Nigeria and Botswana. These studies reported a 18% (range 10–24%) risk of morbidity 6–16 weeks post‐infant male circumcision . The case definitions used in those studies were similar to our study.…”

Can Combination Prevention Strategies Reduce HIV Transmission in Generalized Epidemic Settings in Africa? The HPTN 071 (PopART) Study Plan in South Africa and Zambia

“…96-99 The study builds on work from an ongoing study of the Botswana-Harvard AIDS Institute Partnership in Mochudi, a community of 40,000 persons in Botswana. 100-105 PEPFAR and the BMGF have subsequently sponsored a harmonization effort between the HPTN 071(PopART) study and the Botswana Combination Prevention Project that shares similar goals as those of HPTN 071(PopART), but has a different study design.…”

Factors Associated with Preference for Early Infant Male Circumcision Among a Representative Sample of Parents in Homa Bay County, Western Kenya

“…After a ''catch-up'' period of circumcising adolescent and adult males who are at highest risk of acquiring HIV in the short term, several governments including the Government of Kenya, intend to scaleup EIMC for cost-efficient HIV prevention ( Ref 11]. EIMC studies and/or service provision have begun in Botswana, Kenya, Lesotho, Swaziland, Uganda, Zambia and Zimbabwe ( Ref 8,[12][13][14][15][16]. Previous acceptability studies have indicated several common barriers to EIMC services in east and Southern Africa including: fear of pain, bleeding, death and other adverse events associated with the procedure, and cultural opposition to EIMC ( Ref 17].…”
