The clinical outcome of cirrhotic patients with hepatocellular carcinoma (HCC) depends both on the residual liver function and tumor characteristics. However, the relative prognostic weight of these variables is not well defined. The aims of this study were to verify the value of known prognostic factors and to devise a prognostic index more sensitive than the commonly used Okuda stage. A retrospective analysis of the cases of HCC diagnosed at 16 Italian institutions from 1990 to 1992 was performed. Overall survival was the only end point used in the analysis. The Cox model, stratified by locoregional treatment, was used for multivariate analyses. The final model was derived from 10 randomly chosen training samples, and the prognostic validity of the Cancer of the Liver Italian Program (CLIP) score was assessed on the corresponding testing samples. Four hundred thirty-five cases of HCC were collected. As of January 1997, 313 patients (72%) were deceased. Overall median survival was 20 months. At multivariate analysis, independent predictive factors of survival were Child-Pugh stage, tumor morphology, alpha-fetoprotein (AFP), and portal vein thrombosis. A simple scoring system (CLIP score) was thus produced, assigning linear scores (0/1/2) to the covariates. Compared with Okuda stage, the CLIP score, structured as a six-category tool, has a greater discriminant ability, revealing a class of patients with an impressively more favorable prognosis and another class with a relatively shorter life expectancy. The CLIP score is a new prognostic system that accounts for both liver function and tumor characteristics. It is easy to calculate and appears to give more precise information than the Okuda stage.

In this large, prospective, multinational cohort, more than one half of all cases of non-HACEK gram-negative bacillus endocarditis were associated with health care contact. Non-HACEK gram-negative bacillus endocarditis is not primarily a disease of injection drug users.

Summary. The pathogenesis of thrombocytopenia in chronic hepatitis is not well known. This study evaluated the relationship between liver injury, serum thrombopoietin, splenomegaly and thrombocytopenia in chronic viral hepatitis. Two hundred and nine patients were enrolled, 85 with splenomegaly and 124 without. Thrombocytopenia was present in 71% and 23% of patients with or without splenomegaly respectively. In subjects with low platelet count, those with splenomegaly showed significantly lower platelet numbers than those without splenomegaly. The spleen size correlated with portal hypertension. An inverse correlation between spleen size and platelet count was observed (r 20´54; P , 0´0001). In patients without splenomegaly, thrombocytopenia was associated with the grade of fibrosis; platelet counts were the highest in patients with fibrosis 0±2, lower in those with grade 3 (P , 0´008) and lowest in those with grade 4 (P , 0´05). These findings were independent of demographic and biochemical characteristics, hepatic necroinflammatory activity, portal hypertension and splenomegaly. Patients with normal platelet counts showed higher thrombopoietin levels than those with low platelet counts (P , 0´0001). An inverse correlation between thrombopoietin levels and fibrosis grade was observed (r 2 0´50; P , 0´0001). Median thrombopoietin levels were 58 and 27 pg/ml for fibrosis grade 0±1 and grade 4 respectively (P , 0´001). These data indicate that advanced hepatic fibrosis, causing an altered production of thrombopoietin and portal hypertension, plays the central role in the pathogenesis of thrombocytopenia in chronic viral hepatitis.

Clinical and epidemiological characteristics of Streptococcus bovis endocarditis were prospectively studied among 199 patients with definite endocarditis. Thirty patients (15.1%) had S. bovis endocarditis. Compared with patients with non-S. bovis endocarditis, these 30 patients were older (mean age, 58.6+/-12.4 years vs. 46.0+/-17.0 years; P<.001) and had higher rates of bivalvular involvement (43.3% vs. 7.7%; P<.001), embolism (73.3% vs. 40.2%; P=.002), and diskitis (23.3% vs. 0.6% P<.001). In patients with S. bovis biotype I (S. bovis I) endocarditis, advanced liver disease was present in 56.7%, compared with 15.3% of patients with non-S. bovis endocarditis (P<.001), and colonic adenoma was present in 46.7%. The in-hospital mortality rate (16.7%) was correlated with delayed diagnosis and advanced liver diseases. In our city, S. bovis I endocarditis is frequently correlated with liver diseases; diskitis may be the first sign of the disease.
