spontaneous bacterial peritonitis in cirrhosis predictive factors of infection resolution and survival in patients treated with cefotaxime
Hepatology, 1993Co-Authors: C Toledo, Joanmanuel Salmeron, Antoni Rimola, Miquel Navasa, Vicente Arroyo, Josep Llach, Angels Gines, Pere Gines, Joan RodesAbstract:Cefotaxime is the most commonly used antibiotic for initial therapy of spontaneous bacterial peritonitis in cirrhosis. However, since the introduction of cefotaxime no study has been performed to investigate factors influencing prognosis in cirrhotic patients with this type of infection. In this study, predictive factors for infection resolution and patient survival were investigated in 213 consecutive episodes of spontaneous bacterial peritonitis in 185 cirrhotic patients. All patients were initially treated with cefotaxime. One hundred sixty-five episodes (77%) resolved with cefotaxime alone, and two more episodes (1%), initially unresponsive to cefotaxime, were cured after modification of antibiotic therapy. In a multivariate analysis (stepwise logistic regression), only 4 of 51 clinical and laboratory variables obtained at the time of diagnosis of infection were identified as independent predictors of infection resolution: band neutrophils in white blood cell count, community-acquired vs. hospitalacquired peritonitis, blood urea nitrogen Level and serum Aspartate Aminotransferase Level. No patient experienced serious adverse effects related to cefotaxime. Eighty-two patients died during hospitalization (38% mortality rate in relation to the 213 episodes of peritonitis). In the multivariate analysis, six variables were independently correlated with survival: blood urea nitrogen Level, serum Aspartate Aminotransferase Level, community-acquired vs. hospitalacquired peritonitis, age, Child-Pugh score and ileus. No microbiological data had predictive value for infection resolution or survival. These results indicate that in cirrhotic patients with spontaneous bacterial peritonitis treated with cefotaxime, infection resolution and patient survival may be predicted by several clinical and laboratory variables obtained at the time of infection diagnosis; the most important are blood urea nitrogen Level, serum Aspartate Aminotransferase Level and site (community or hospital) of peritonitis acquisition.

type of donor aortic preservation solution and not cold ischemia time is a major determinant of biliary strictures after liver transplantation
Liver Transplantation, 2001Co-Authors: Jacques Pirenne, Takashi Koshiba, Frank Van Gelder, Willy Coosemans, Raymond Aerts, Bridget Gunson, Inge Fourneau, Darius F Mirza, Werner Van Steenbergen, Johan FeveryAbstract:The development of biliary strictures (BSs) after liver transplantation (LT) continues to affect 10% to 30% of patients, causing substantial morbidity. The cause of BSs is multifactorial, including technical, immune, and, in particular, ischemic factors. The importance of adequate flushing of the peribiliary arterial tree has been stressed. We hypothesized that high-viscosity (HV) preservation solutions in the donor do not completely flush the small donor peribiliary plexus, leading to inadequate preservation of the bile ducts and posttransplant BSs. To test this hypothesis, we retrospectively compared the incidence of BSs in 2 groups of adults undergoing LT using different types of aortic preservation solution in the donor: group 1 (n = 24), low-viscosity (LV) Marshall solution; and group 2 (n = 27), HV University of Wisconsin (UW) solution. All donors in both groups received additional portal flushes with UW. All LTs were performed between November 1995 and August 1998 at 2 centers by the same surgeon, eliminating a technical bias. Terminal duct-to-duct anastomosis was performed in all recipients except 1 patient in group 1, who underwent a bile duct-to-jejunum anastomosis. BSs were first suspected on clinical and biochemical grounds and then confirmed by endoscopic retrograde cholangiopancreatography. Identical medical protocols were used in all patients. One-year patient survival rates in groups 1 and 2 were 92% and 100%, respectively (P = .9). One-year graft survival was identical to patient survival. The incidence of BSs in group 1 was 4.1% (1 of 24 patients), compared to 29.7% in group 2 (8 of 27 patients; P = .02). The BS in group 1 occurred 4 months post-LT and was anastomotic. BSs in group 2 occurred between 1 and 12 months post-LT and were anastomotic, extrahepatic, intrahepatic, or combined intrahepatic and extrahepatic. There were no significant differences in the following factors between groups 1 and 2: donor age, local versus imported liver, split-liver or full-liver transplantation, incidence of multiple vessels in the donor liver, indications for LT, recipient age, T-tube versus no T-tube, post-LT peak Aspartate Aminotransferase Level, and treatment for rejection. There was no hepatic artery thrombosis or primary nonfunction in either group. Interestingly, cold ischemia time (CIT) was longer in group 1, which had the least incidence of BSs (692 ± 190 v 535 ± 129 minutes in group 2; P = .001). Follow-up was longer in group 1 (28.9 ± 8.3 v 15.6 ± 8 months in group 2; P = .0001). Preservation costs per procurement were 1.9 times greater in the UW group than in the Marshall group. Donor aortic flushing with an HV preservation solution leads to more frequent BSs compared with an LV preservation solution. The impact of preservation solution outweights the previously described deleterious impact of prolonged CIT. Mixed preservation solution (Marshall solution in the aorta, UW solution in the portal vein) might protect against BS formation while providing optimal liver graft preservation, function, and survival despite a mean CIT longer than 10 hours.
