Article: Evaluation of paraumbilical vein as a prognostic index of severe liver cirrhotic patients with portal-systemic shunts.[show abstract] [hide abstract]
ABSTRACT: The aim of this study was to predict the outcome in severe liver cirrhotic patients with portal-systemic shunts. One-hundred and sixteen patients with liver cirrhosis diagnosed as Child-Pugh class B and C with portal-systemic shunts confirmed by abdominal ultrasonography, computed tomography and magnetic resonance imaging were enrolled in this study. Twenty-three factors were evaluated concerning clinical laboratory parameters and extracted prognostic factors using the Cox proportional hazards model, and the prognostic index (PI) was prepared by combining these factors. The cumulative survival rates after admission were 64.6%, 35.6% and 25% after 1, 3 and 5 years, respectively. Using multivariate analysis, age, the presence of hepatocellular carcinoma (HCC), portal vein tumor thrombosis (PVTT) and paraumbilical vein (PUV) shunt were selected as significant prognostic factors that contributed independently to the prognosis of severe liver cirrhotic patients with portal-systemic shunts. The PI was calculated with the following formula using these 4 factors. PI = 0.042 x Age + 0.913 x HCC + 0.989 x PVTT + 1.079 x PUV shunt. The group with a high score for PI was found to die with significantly higher frequency than the group with a low score. It was found that tumor related factors and PUV shunt were the most important factors for severe liver cirrhotic patients with portal-systemic shunts. The PI is suggested to be an appropriate index to predict the prognosis for these patients.Minerva gastroenterologica e dietologica 01/2007; 52(4):371-8.
Article: Prognostic index of liver cirrhosis with ascites with and without hepatocellular carcinoma.[show abstract] [hide abstract]
ABSTRACT: In Japan, the incidence of liver cirrhosis caused by hepatitis viruses is higher, and cirrhosis is more likely to be complicated by hepatocellular carcinoma, than in Western countries. The aim of this study was to predict the outcome in liver cirrhosis with ascites with and without hepatocellular carcinoma. The subjects were 146 patients with liver cirrhosis complicated by ascites. Forty-six factors were evaluated concerning clinical laboratory parameters and extracted prognostic factors using the Cox proportional hazards model. The mean duration of the follow-up period was 634.9 days, during which 89 (61%) of the patients died, 27 (18.5%) survived, and 30 (20.6%) were lost to follow-up. The cumulative survival rate after the onset of ascites was 59.7% after 1 year, 44.5% after 2 years, and 29.5% after 5 years. Multivariate analysis indicated 9 factors, i.e. age, total bilirubin (T-Bil), alkaline phosphatase (ALP), blood urea nitrogen (BUN), alpha-fetoprotein (AFP), mean arterial pressure (MAP), gastrointestinal bleeding, infection, and portal vein tumor thrombosis (PVTT), as independent prognostic factors. The prognostic index (PI) was calculated by the following formula using these 9 factors. PI = 0.045 x age + 0.180 x T-Bil + 0.088 x ALP + 0.020 x BUN + 0.467 x AFP + (-0.022 x MAP) + 0.662 x gastrointestinal bleeding + 0.521 x infections + 0.882 x PVTT. Prediction of the outcome using PI based on the 9 factors provides additional information for the determination of the therapeutic approach in cirrhotic patients with ascites with and without hepatocellular carcinoma.Scandinavian Journal of Gastroenterology 01/2005; 39(12):1272-9. · 2.02 Impact Factor
