Human Immunodeficiency Virus can be spread through sexual contact , blood products and vertical transmission of
the mother to the fetus . The high incidence of HIV / AIDS around the world in women over 15 years old and children
under the age of 15 years gives an overview of HIV / AIDS cases in pregnant women likely to have a high incidence.
HIV viral RNA viruses belonged to two different types , namely HIV - 1 and HIV - 2 . Most cases are caused by HIV
- 1. HIV primarily infects CD4 lymphocytes or T helper ( Th ), the numbers will decrease , as well as the function of
the immune system will decrease. During pregnancy occurs emphasis on immune cells, with or without HIV infection.
Study in France showed no significant progression between the immune system of pregnant women with HIV and
normal pregnant women . T reg on HIV infection in lymphoid tissue accumulated and the number of T reg post
partum was higher in patients with HIV infection compared to HIV- negative . Human Leukocyte antigen - G ( HLA
- G ) inhibits cell-mediated immune response and can penetrate the placenta spread of HIV - 1 infection and increase
the risk of vertical transmission . Major histocompatibility complex ( MHC ) encodes HLA - G to inhibit natural killer
cells ( NK cells) that supports the entry of the virus passes through the placental barrier in HIV- 1 positive pregnant
women . HIV infection activates CD8 expressing HLA - DR antigen . CD8 immune activation in chronic HIV becomes
a factor decreasing CD4 count . The expression of HLA - DR and CD38 on CD8 T lymphocytes that recognize CD4
eliminated by HIV infection Total CD8 , CD38 , and HLA - DR is reduced in HIV- positive pregnant women may be
a prognostic parameters of immune status.
