To analyze factors related to the development of infection soon after a liver transplant.Retrospective study of 1000 liver transplants in adults between 1991 and 2004. Pre-, intra- and postoperative variables of recipients were analyzed in 2 groups according to whether infection did or did not develop.Infection developed in 151 patients. Bacterial infections were the most common type. Significant risk factors for infection in the multivariate analysis were sex (odds ratio [OR], 0.54; 95% confidence interval [CI], 0.33-0.90); Child-Pugh stage (OR, 1.89; 95% CI, 1.29-2,77); hepatitis C virus cirrhosis (OR, 0.58; 95% CI, 0.34-0.99); post-reperfusion syndrome (OR, 1.82; 95% CI, 1.03-3.21); vena cava preservation technique (OR, 0.43; 95% CI, 0.22-0.84); history of diabetes mellitus (OR, 2.38; 95% CI, 1.34-4.22); respiratory distress syndrome (OR, 6.60; 95% CI, 1.16-37.45); pulmonary edema (OR, 2.36; 95% CI, 1.44-3.86); renal dysfunction (OR, 3.25; 95% CI, 1.89-5.60); acute renal insufficiency (OR, 20.24; 95% CI, 9.88-41.46); neurological alterations (OR, 3.36; 95% CI, 1.94-5.821); postoperative bleeding (OR, 2.80; 95% CI, 1.32-5.97); graft dysfunction (OR, 2.07; 95% CI, 1.21-3.53); primary graft failure (OR, 0.07; 95% CI, 0.01-0.33).Infection is a serious complication that continues to be difficult to control. Certain risk factors can be improved with careful management (kidney failure, pulmonary edema) or appropriate donor-recipient matching (initial dysfunction). Others, however, are inherent to the procedure (post-reperfusion syndrome, sex) or to immunosuppression, which acts as a true mediator of infection with regard to both its appearance and its clinical manifestation. |
