HIV Vertical Transmission in Vietnam
Counseling on Formula Feeding and Antiretroviral Prophylaxis Successfully Reduced Transmission of HIV-1 From Mother to Child in Northern Vietnam
Prevention of HIV-1 transmission from mother-to-child by non-breast-feeding is complicated by increased infant mortality in developing countries. However, extensive counselling about formula feeding turned out safe in Vietnam, a middle-income country.Extensive counselling together with formula feeding and antiretroviral therapy reduced vertical transmission of HIV-1 considerably.

Observation 135 HIV mother to check up and delivery in the Obstetric and Gynecology in two big city in Northern Vietnam (Hanoi and Haiphong)and follow up their children from the birth to 18 months. They were provide the antiretroviral by the National program for prevention of mother-to-child transmission of HIV, also the counseling estimates 6 hours for each mother-child pair while study progressing. Using the Nested PCR to diagnosis HIV infected in the children in difference time point before 18 months. Our Outcome are

  • The rate of HIV transmission form mother to child in our study is 6,7%(9?135). In utero is 1,5% and 5% in gestation.
  • Sixty-nine percent of HIV pregnant women were get antiretroviral. Most of them (84%) get nevirapine at delivery (6 children HIV infected). The rest get triple antiretroviral(2 infected child).
  • Selective cesarean section not comment for HIV pregnant women.
  • Non breast feeding were recommended and all mothers chose formula feeding to their child so that we had no data for transmission by breast milk.
  • Two HIV infected child die before 18months versus non die in uninfected child.
  • CD4 T cell count lower than 200/microliter were observed dominate in mother infected child.
Observational Model: Cohort
Time Perspective: Prospective

Retention:   Samples With DNA
Peripheral EDTA blood samples were collected from the child at birth (1-2 days), at 1, 3, 6, 12, and 18 months of age and processed at the Molecular Laboratory in the Hanoi Obstetric and Gynaecology hospital. The maternal blood samples were taken at the same day as the first sample of their child. Three ml EDTA blood was taken from the mother and 2 ml from the child. The blood was processed within 8 hours. Cells and plasma were stored separately at - 20 Celcius degree.
Probability Sample

HIV-1 infected pregnant women were identified in the Obstetric and Gynaecology hospitals in Hanoi (2004-2007) and Haiphong (2006-2007).

They were encouraged to participate in a prospective study with regular clinical follow up of their children from birth to 12-18 months of age. All participants signed an informed consent.
