Predictors of operative outcome in patients with human immunodeficiency virus infection and acquired immunodeficiency syndrome

Background: Plasma viral load has recently been associated with clinical outcome in patients with human immunodeficiency virus (HIV) infection and acquired immunodeficiency syndrome (AIDS). We hypothetized that, in addition to CD4 lymphocytes, plasma HIV-1 RNA counts are predictive of postoperative outcome. Methods: HIV-infected and AIDS patients admitted to a major teaching hospital requiring invasive or surgical procedures were retrospectively analyzed for postoperative outcome. Preoperative and postoperative immune cell counts including plasma HIV-1 RNA counts were recorded. Chi-square analysis, Fisher’s exact test, and multivariate regression were performed with statistical significance P ≤0.05. Results: Fifty-five consecutive patients between 14 and 62 years of age were admitted in a 1-year period and underwent 64 diagnostic and therapeutic procedures. Fourteen (22%) postoperative infections and 18 (28%) complications other than infection, with an overall mortality of 11%, were documented. Total preoperative white blood cell count ([WBC] P
