Patient Benefited From HIV Treatment Shortly After Birth

Researchers from the HIV, Inflammation and Persistence Unit at the Institut Pasteur in Paris believe that the patient has benefited from treatment initiated shortly after birth and ended 6 years later.

The case will be presented at the 8th International AIDS Society (IAS) Conference on HIV Pathogenesis, Treatment and Prevention in Vancouver, Canada, by Dr. Asier Sáez-Cirión.
"Our work has demonstrated for the first time that long-term remission from HIV infection can be achieved in a child infected during the perinatal period, following discontinuation of effective antiretroviral therapy begun very early on, during the first few months of life," reports Dr. Sáez-Cirión.
The patient in question was born in 1996 and infected with HIV either at the end of pregnancy or childbirth. Despite a 6-week course of the antiretroviral drug zidovudine, she was diagnosed as HIV-positive 1 month after birth.
Two months later, doctors found that the patient had a very high quantity of the virus in her blood, prompting them to initiate a course of treatment involving four antiretroviral drugs. This treatment continued until she was lost to follow-up at the age of 6, at which point her parents stopped the therapy.
However, one year later, the patient was assessed by a medical team who found that her viral load was undetectable. Her doctors chose not to resume antiretroviral therapy, and to date her viral load is still undetectable. Her CD4 cell count has also remained consistent, indicating that her HIV is stable.
"This girl has none of the genetic factors known to be associated with natural control of infection," states Dr. Sáez-Cirión. "Most likely she has been in virological remission for so long because she received a combination of antiretrovirals very soon after infection."

Case supports immediate antiretroviral therapy for babies born with HIV

The case is similar on many levels to the adult patients of the ANRS VISCONTI study - a cohort of 20 patients who received antiretroviral therapy in the first few months after HIV infection. After an average of 3 years of therapy, these patients demonstrated control of the virus for an average of 10 years without further treatment.

Dr. Sáez-Cirión explains that both the adult patients of the ANRS VISCONTI cohort and the young girl received a standard level of treatment; the only distinguishing factor in these cases is that treatment was initiated very soon after HIV infection occurred.
 
Although this case indicates that long-term remission is possible in children as well as adults, Dr. Sáez-Cirión cautions that such cases are still rare.

He refers to the case of the "Mississippi baby" - the only previous known case of HIV remission in a child that was at the time heralded as evidence of HIV being cured. Unfortunately, the child was found to have the disease again 27 months after antiretroviral therapy was stopped.

Prof. Jean-François Delfraissy, director of ANRS (France's National Agency for Research on AIDS), states that the patient's remission should not be equated with a cure:CONTINUE READING
