The effects of occlusive portal vein thrombosis (PVT) on the survival of patients with cirrhosis are unknown. This was a retrospective cohort study at a single center. The main exposure variable was the presence of occlusive PVT. The primary outcome measure was time-dependent mortality. A total of 3295 patients were analyzed, and 148 (4.5%) had PVT. Variables independently predictive of mortality from the time of liver transplant evaluation included age [hazard ratio (HR), 1.02; 95% confidence interval (CI), 1.01-1.03], Model for End-Stage Liver Disease (MELD) score (HR, 1.10; 95% CI, 1.08-1.11), hepatitis C (HR, 1.44; 95% CI, 1.24-1.68), and PVT (HR, 2.61; 95% CI, 1.97-3.51). Variables independently associated with the risk of mortality from the time of liver transplant listing included age (HR, 1.02; 95% CI, 1.01-1.03), transplantation (HR, 0.65; 95% CI, 0.50-0.81), MELD (HR, 1.08; 95% CI, 1.06-1.10), hepatitis C (HR, 1.50; 95% CI, 1.18-1.90), and PVT (1.99; 95% CI, 1.25-3.16). The presence of occlusive PVT at the time of liver transplantation was associated with an increased risk of death at 30 days (odds ratio, 7.39; 95% CI, 2.39-22.83). In conclusion, patients with cirrhosis complicated by PVT have an increased risk of death. Liver Transpl 16:83-90, 2010.
As the outcomes of heart, liver, and lung transplantation continue to improve, more patients will present for subsequent renal transplantation. It remains unclear whether these patients benefit from induction immunosuppression. We retrospectively reviewed induction on solid organ graft recipients who underwent renal transplant at our center from January 1, 1995 to March 30, 2007. Induction and the non-induction groups were compared by univariate and Kaplan-Meier analyses. There were 21 patients in each group, with mean follow-up of 4.5-6.0 years. Forty-seven percent of patients receiving induction had a severe post-operative infection, compared with 28.6% in the non-induction group (p = NS). The one yr rejection rate in the induction group was 9.5% compared with 14.3% for non-induction (p = NS). One-yr graft survival was 81.0% and 95.2% in the induction and non-induction group (p = NS). In summary, there is a trend toward lower patient and graft survival among patients undergoing induction. These trends could relate to selection bias in the decision to prescribe induction immunosuppression, but further study is needed to better define the risks and benefits of antibody-induction regimens in this population.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
