Immunologic status and virologic outcomes in repeat pregnancies to HIV-positive women not on antiretroviral therapy at conception: a case for lifelong antiretroviral therapy?

ABSTRACT

During their second pregnancy with diagnosed HIV (n = 1177), two-fifths of women in the UK/Ireland not on antiretroviral therapy (ART) at conception had an immunological indication for treatment (CD4(+) <350 cells/µl), of whom nearly half had CD4(+) at least 350 cells/µl in their previous pregnancy. Those initiating ART during pregnancy had a 4.3-fold increased odds of detectable viral load at delivery compared with those conceiving on treatment, suggesting that continuation of ART after pregnancy may be beneficial for many women.
