Earlier Circumcision In Males May Be Effective Intervention To Slow Rates Of HIV And HPV Transmission In South Africa

07.10.2011
According to Anna R. Giuliano, Ph.D., program leader in cancer epidemiology at Moffitt Cancer Center in Tampa, Fla., and colleagues in the Netherlands, earlier circumcision of males in South Africa may be a positive step in slowing the spread of both HIV and the human papillomavirus (HPV). Their commentary and data were published in a recent issue of the British medical journal The Lancet Infectious Diseases (Vol. 11) 581-582.

"Countries with high incidences of HIV also have high incidences of cancer-related HPV," said Giuliano. "This is especially true in South Africa."

Commenting on a study related to circumcision and HIV and HPV transmission, Giuliano and her colleagues note that studies have shown that circumcision of HIV-infected men does not reduce HPV transmission to their female partners. Many factors may account for this lack of efficacy. However, Giuliano and colleagues suggest that the high prevalence of HPV among the HIV-infected men (73 percent in the intervention group and 69 percent in the control group) and the high prevalence of HIV among the female partners of greater than 60 percent, relates to the lack of efficacy of male circumcision. In that study, it was pointed out that the high and sustained prevalence of HPV among the HIV-infected individuals is "likely to overwhelm any preventative effect of circumcision."

"Male circumcision is important for reduction of not only HIV infection but also HPV infection in HIV-negative men and their female partners," said Giuliano. "However, its efficacy seems limited to HIV-negative men. These results suggest the need for early circumcision to achieve maximum effectiveness in populations with a high incidence of HIV and cervical cancer."

For maximum reductions in HIV and HPV infections and related diseases in women, such as cervical cancer, the researchers recommend that both circumcision and HPV vaccination of the male population should be delivered prior to sexual debut.

About Moffitt Cancer Center
Located in Tampa, Florida, Moffitt Cancer Center is an NCI Comprehensive Cancer Center - a designation that recognizes Moffitt's excellence in research and contributions to clinical trials, prevention and cancer control. Moffitt currently has 14 affiliates in Florida, one in Georgia, one in Pennsylvania and two in Puerto Rico. Additionally, Moffitt is a member of the National Comprehensive Cancer Network, a prestigious alliance of the country's leading cancer centers, and is listed in U.S. News & World Report as one of "America's Best Hospitals" for cancer. Moffitt marks a very important anniversary in 2011 - 25 years committed to one mission: to contribute to the prevention and cure of cancer.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
