title: Mode of delivery and postpartum HIV-1 disease progression: the Women and Infants Transmission Study.
abstract: OBJECTIVE
  To assess the relationship between mode of delivery and subsequent maternal HIV-1 disease progression.
  
  
  METHODS
  Changes in CD4+ lymphocyte percentage (CD4%) and plasma HIV-1 RNA concentration (HIV RNA), and time to progression to AIDS or death among HIV-1-infected women were compared according to mode of delivery [cesarean section before labor and ruptured membranes (SCS), cesarean section after labor and/or after ruptured membranes (NSCS), and vaginal delivery]. Generalized estimating equations were used to compare changes in adjusted mean CD4% and HIV RNA counts by mode of delivery. Cox proportional hazard models were used to assess differences in time to AIDS or death.
  
  
  RESULTS
  In adjusted analyses, there were no clinically important differences in HIV-1 disease progression according to mode of delivery (SCS, n = 183; NSCS, n = 221; vaginal, n = 1087), as assessed by changes in CD4% and HIV RNA during the 18 months following delivery, and by progression to AIDS or death during a mean postpartum follow-up of 2.66 years.
  
  
  CONCLUSIONS
  The present results suggest that, among HIV-1-infected women in North America, mode of delivery is not associated with subsequent HIV-1 disease progression.
