BACKGROUND: The impact of spontaneous portosystemic shunt (SPSS) on decompensated events and mortality for patients with hepatitis B-related cirrhosis remains poorly investigated. AIMS: To evaluate the prevalence, clinical characteristics, and outcomes of SPSS among patients with hepatitis B-related cirrhosis. METHODS: Patients who were diagnosed with hepatitis B-related cirrhosis were retrospectively recruited. All eligible patients were classified into SPSS and non-SPSS groups and their clinical characteristics and outcomes were compared and analyzed. RESULTS: Of the 1282 patients included in this study, SPSS was identified in 488 patients (38.1%). SPSS group had more severe liver function impairment, higher prevalence and severity of esophageal and gastric varices (EGV), and a higher prevalence of EGV bleeding (EGVB), portal vein thrombosis (PVT), hepatic encephalopathy (HE), ascites, and hepatocellular carcinoma (HCC, all P<0.05). During the follow-up period, SPSS group experienced a significantly higher incidence of EGVB, PVT, and HE (all P<0.05); however, there was no significant difference in the incidence of ascites, HCC, and mortality between the two groups (all P>0.05). CONCLUSION: With hepatitis B-related cirrhosis, SPSS was common and characterized by severe liver damage and a high prevalence of decompensated events. Moreover, patients with SPSS had higher risks of EGVB, PVT, and HE.
The purpose of this study was to evaluate the diagnostic efficiency for hepatocellular carcinoma (HCC) with the combined analysis of alpha-l-fucosidase (AFU), alpha-fetoprotein (AFP) and thymidine kinase 1 (TK1). Serum levels of AFU, AFP and TK1 were measured in: 116 patients with HCC, 109 patients with benign hepatic diseases, and 104 normal subjects. The diagnostic value was analyzed using the logistic regression equation and receiver operating characteristic curves (ROC). Statistical distribution of the three tested tumor markers in every group was non-normally distributed (Kolmogorov-Sminov test, Z = 0.156-0.517, P < 0.001). The serum levels of AFP and TK1 in patients with HCC were significantly higher than those in patients with benign hepatic diseases (Mann-Whitney U test, Z = -8.570 to -5.943, all P < 0.001). However, there was no statistically significant difference of AFU between these two groups (Mann-Whitney U test, Z = -1.820, P = 0.069). The levels of AFU were significantly higher in patients with benign hepatic diseases than in normal subjects (Mann-Whitney U test, Z = -7.984, P < 0.001). Receiver operating characteristic curves (ROC) in patients with HCC versus those without HCC indicated the optimal cut-off value was 40.80 U/L for AFU, 10.86 µg/L for AFP and 1.92 pmol/L for TK1, respectively. The area under ROC curve (AUC) was 0.718 for AFU, 0.832 for AFP, 0.773 for TK1 and 0.900 for the combination of the three tumor markers. The combination resulted in a higher Youden index and a sensitivity of 85.3%. The combined detection of serum AFU, AFP and TK1 could play a complementary role in the diagnosis of HCC, and could significantly improve the sensitivity for the diagnosis of HCC.
