Researchers say they have, for the first time, cured a baby born with HIV -- a development that could help improve treatment of babies infected at birth.
A baby girl in Mississippi who was
born with HIV has been cured after very early treatment with standard HIV
drugs, U.S. researchers reported on Sunday, in a potentially ground-breaking
case that could offer insights on how to eradicate HIV infection in its
youngest victims.
The child's story is the first
account of an infant achieving a so-called functional cure, a rare event in
which a person achieves remission without the need for drugs and standard blood
tests show no signs that the virus is making copies of itself.
More testing needs to be done to see
if the treatment would have the same effect on other children, but the results
could change the way high-risk babies are treated and possibly lead to a cure
for children with HIV, the virus that causes AIDS.
The baby was infected by her HIV-positive mother,
and her treatment with therapeutic doses of antiretroviral drugs began even
before her own positive blood test came back.
The typical protocol for high-risk newborns is to
give them smaller doses of the drugs until results from an HIV blood test is available
at six weeks old. Tests showed the baby's viral count steadily
declined until it could not longer be detected 29 days after her birth.
The child was given follow-up treatment with
antiretrovirals until 18 months, at which point doctors lost contact with her
for 10 months. During that period she was not taking antiretrovirals.
Researchers then were able to do a series of blood
tests -- and none gave an HIV-positive result.
Natural viral suppression without treatment is an
exceedingly rare occurrence, seen in fewer than half a percent of HIV-infected
adults, known as "elite controllers," whose immune systems are able
to rein in viral replication and keep the virus at clinically undetectable
levels.
