HIV Infection Cured Through Very Early Treatment

HIV Infection Cured Through Very Early Treatment

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.


 When the baby girl was born in a rural hospital in July 2010, her mother had just tested positive for HIV infection. Because her mother had not received any prenatal HIV treatment, doctors knew the child was at high risk of infection. They transferred her to the University of Mississippi Medical Center in Jackson, where she came under the care of Dr. Hannah Gay, a pediatric HIV specialist.


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.

Awesome News!!!
