Researchers have reported success with a vaccine believed to protect against chancroid, a sexually transmitted disease//. If approved for use, it could put an end to this devastating disease that has been haunting sub-Saharan Africa. This could eventually result in a 10-fold reduction in transmission of HIV in the same region, if approved for commercial use.
HIV plagues more than 25 million people in sub-Saharan Africa, according to the World Health Organization, and efforts to develop a vaccine against the virus have achieved limited success.
But what if a vaccine against another sexually transmitted infection found widely in that region of Africa – chancroid – was relatively easy to develop and could reduce transmission of HIV as much as 10-fold?
That may be the case, according to researchers from the University of North Carolina at Chapel Hill's School of Medicine and N.C. State University's College of Veterinary Medicine.
Their study appears in the April issue of the journal Infection and Immunity. The lead author is Dr. Galyna Afonina, postdoctoral research associate in the UNC Center for Infectious Diseases. Senior author is Dr. Christopher Elkins, research associate professor in the departments of medicine and microbiology and immunology in UNC's School of Medicine.
Chancroid, a sexually transmitted disease that causes genital ulcers, is rare in the United States but takes hold in communities that have little or no access to health care, such as in Africa. Recent studies show that genital ulcer diseases such as chancroid can enhance HIV transmission three- to 10-fold.
‘There is considerable evidence that genital ulcers are independent risk factors for the transmission of HIV, and chancroid may be the most important one,’ said Elkins.
Chancroid is caused by a bacterium, Haemophilus ducreyi, that normally infects only humans. Unlike most bacteria, Haemophilus species are unable to syntPage: 1 2 3 Related medicine news :1
