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 <0.01), preoperative percent lymphocyte count (P <0.01), absolute postoperative CD4 lymphocyte count (P <0.01), and postoperative plasma viral load (P <0.0001) are associated with mortality. Multivariate regression indicated that postoperative percent CD4 lymphocyte count is an independent predictor of both postoperative infection and other complications (P <0.05, R = 0.848, power = 0.9911), while the decrement in percent CD4 lymphocyte count is an independent predictor of postoperative complications other than infection (P <0.05, R = 0.596, power = 0.7838). CONCLUSIONS In accordance with the medical literature for clinical outcome in HIV-infected and AIDS patients, both immune cell counts and HIV-1 RNA counts were found to associate with postoperative mortality. However, the postoperative and decrement in percent CD4 lymphocyte proved to be the independent predictors of postoperative complications.

D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D011183 Postoperative Complications Pathologic processes that affect patients after a surgical procedure. They may or may not be related to the disease for which the surgery was done, and they may or may not be direct results of the surgery. Complication, Postoperative,Complications, Postoperative,Postoperative Complication
D011237 Predictive Value of Tests In screening and diagnostic tests, the probability that a person with a positive test is a true positive (i.e., has the disease), is referred to as the predictive value of a positive test; whereas, the predictive value of a negative test is the probability that the person with a negative test does not have the disease. Predictive value is related to the sensitivity and specificity of the test.

D000163 Acquired Immunodeficiency Syndrome An acquired defect of cellular immunity associated with infection by the human immunodeficiency virus (HIV), a CD4-positive T-lymphocyte count under 200 cells/microliter or less than 14% of total lymphocytes, and increased susceptibility to opportunistic infections and malignant neoplasms. Clinical manifestations also include emaciation (wasting) and dementia. These elements reflect criteria for AIDS as defined by the CDC in 1993.

D012189 Retrospective Studies Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
