Medical experts
have discovered a potentially catastrophic link between
the antiretroviral medication used to treat HIV/AIDS and the
activation of a dormant leprosy infection, The New York Times reported last week. This has been
especially prevalent in patients receiving treatment in
developing nations, where inexpensive AIDS treatments
are finally just arriving.
Although leprosy
is easily treated with antibiotics, treatment often
takes an extra toll on those patients who have AIDS. Doctors
unfamiliar with the disease often misdiagnose it as
arthritis or lupus. And though treatment in major
industrial centers like New York and London will
remain relatively simple, experts signal an emerging crisis
in countries that would be unable to handle a second
major disease outbreak.
Though only a
dozen cases have been documented thus far in medical
literature, the Times reported that AIDS
specialists in Brazil, the Caribbean, and other areas
said that many of their patients taking
antiretrovirals have developed painful facial ulcers
or lost feeling in their toes and fingers. This occurs
because as the immune system regenerates during
treatment, newly produced white blood cells transport
the formerly inactive leprosy bacteria to the skin of
the face, hands, and feet.
Countries with
high rates of leprosy infection include Brazil, Myanmar,
Mozambique, and India, a country poised to overtake South
Africa as the country with the world's highest HIV
infection rate.
"This is just the
peak of the iceberg," the Times quoted William Levis,
a New York physician who treats leprosy patients, as
saying. "It's early in the game. Most physicians don't
even think about leprosy, so there's probably much more
around than we know." (The Advocate)
