摘要
Background: Pregnancy has been associated with a decreased risk of HIV disease progression in the highly active antiretroviral therapy (HAART) era. The effect of timing of HAART initiation relative to pregnancy on maternal virologic, immunologic and clinical outcomes has not been assessed. Methods: We conducted a retrospective cohort study from 1997-2005 among 112 pregnant HIV-infected women who started HAART before (N=12), during (N=70) or after pregnancy (N=30). Results: Women initiating HAART before pregnancy had lower CD4+ nadir and higher baseline HIV-1 RNA. Women initiating HAART after pregnancy were more likely to receive triple-nucleoside reverse transcriptase inhibitors. Multivariable analyses adjusted for baseline CD4+ lymphocytes, baseline HIV-1 RNA, age, race, CD4+ lymphocyte count nadir, history of ADE, prior use of non-HAART ART, type of HAART regimen, prior pregnancies, and date of HAART start. In these models, women initiating HAART during pregnancy had better 6-month HIV-1 RNA and CD4+ changes than those initiating HAART after pregnancy (-0.35 vs. 0.10 log(10) copies/mL, P=0.03 and 183.8 vs. -70.8 cells/mm(3), P=0.03, respectively) but similar to those initiating HAART before pregnancy (-0.32 log(10) copies/mL, P=0.96 and 155.8 cells/mm(3), P=0.81, respectively). There were 3 (25%) AIDS-defining events or deaths in women initiating HAART before pregnancy, 3 (4%) in those initiating HAART during pregnancy, and 5 (17%) in those initiating after pregnancy (P=0.01). There were no statistical differences in rates of HIV disease progression between groups. Conclusions: HAART initiation during pregnancy was associated with better immunologic and virologic responses than initiation after pregnancy.
