Abstract
Background
Compared to noninfected patients, human immunodeficiency virus (HIV)-infected patients undergoing surgery have an increased postoperative risk of developing sepsis. We aimed to investigate the preoperative risk factors that affect the incidence of sepsis after surgery in HIV-infected patients.
Methods
Clinical parameters of 215 patients with HIV/acquired immunodeficiency syndrome (AIDS) who had undergone surgery between January 2011 and February 2012 were examined retrospectively for the effect of HIV/AIDS on the incidence of postoperative sepsis.
Results
Logistic regression analysis identified four independent risk factors of postoperative sepsis in HIV-infected patients: CD4 counts [B = −0.007, odds ratio (OR) 0.993]; blood albumin levels (B = −0.077, OR 0.926); surgical infection (B = 1.887, OR 6.598); major surgery (B = 1.013, OR 2.754). The incidence of postoperative sepsis was high with CD4 counts ≤ 100 cells/μl, albumin levels <35 g/L, the presence of surgical infection, the patient had undergone major surgery—81.25%, 39/48; 76.47%, 26/34; 70.73%, 29/41; and 54.76%, 46/84, respectively, compared to that of the total cohort (40.93%, 88/215). When CD4 counts were >350 cells/μl, the incidence of postoperative sepsis was significantly lower (16.36%, 9/55).
Conclusions
Low CD4 cell counts, hypoalbuminemia, surgical infection, and major surgery are independent risk factors for the development of postoperative sepsis among HIV-infected patients. CD4 cell numbers and albumin levels negatively correlated with the incidence of postoperative sepsis, whereas surgical infections and major surgical procedures positively correlated with the incidence of postoperative sepsis.
