Relapse of HIV symptoms seen in a baby girl born in the southern US state of Mississippi, who was thought to have been cleared of the disease, US scientists said Thursday.
The child, now four, was born in 2010 to an HIV-infected mother who was untreated during pregnancy. The baby was given a potent dose of anti-retroviral medication 30 hours after birth, and tested positive for HIV.
AdvertisementShe went off her medication to suppress the human immunodeficiency virus when she was 18 months old, but somehow remained disease-free, showing no detectable level of the virus for more than two years.
Her case raised hopes that doctors may have found a way to cure young children who are born HIV-positive, simply by treating them with drugs early.
"Certainly, this is a disappointing turn of events for this young child, the medical staff involved in the child's care, and the HIV/AIDS research community," said Anthony Fauci, director of the National Institute on Allergy and Infectious Diseases.
The girl was tested during a routine clinical care visit earlier this month, and was found to have detectable HIV levels in her blood, as well as a decreased T-cell count and the presence of HIV antibodies.
All those factors signaled that HIV was actively replicating again in her body.
She is now being treated once again with anti-retroviral medication and is doing well, Fauci said.
"The case of the Mississippi child indicates that early anti-retroviral treatment in this HIV-infected infant did not completely eliminate the reservoir of HIV-infected cells that was established upon infection but may have considerably limited its development and averted the need for anti-retroviral medication over a considerable period," said Fauci.
Researchers must now turn their attention to understanding why and how the child went into remission, with the hope of extending that time period even further in future cases.
