Complications according to mode of delivery among human immunodeficiency virus-infected women with CD4 lymphocyte counts of ≤500/μL

OBJECTIVE: We sought to describe rates of and risk factors for complications by delivery mode among human immunodeficiency virus-infected women with CD4 counts of less than or equal to 500/mu L. STUDY DESIGN: Complication rates were calculated by delivery mode, as follows: planned cesarean delivery performed without labor or rupture of membranes, other cesarean delivery performed after labor or rupture of membranes, or vaginal delivery. Risk factors were evaluated. RESULTS: Major complications in the planned cesarean delivery (n = 37), other cesarean delivery (n = 95), and vaginal delivery (n = 365) groups were amnionitis or endometritis (16%, 27%, and 7%, respectively), wound infection (5%, 8%, and <1%, respectively), and transfusion (8%, 6%, and 3%, respectively). Any peripartum infection occurred among 16 (18%) of those with a CD4 count of <200/mu L and 43 (13%) with a CD4 count of greater than or equal to 200/mu L (P = .17). On multivariate analyses, factors associated with amnionitis-endometritis were cesarean delivery and African American race, and a factor associated with transfusion was third-trimester anemia. CONCLUSION: Endometritis and wound infection occurred more frequently among human immunodeficiency virus-infected women after cesarean than among women undergoing vaginal delivery; however, complication rates overall were within the range reported in human immunodeficiency virus-negative women, Measures to decrease complications in human immunodeficiency virus-infected women, such as greater use of prophylactic antibiotics, should be assessed.
