There are no clear markers or clinical features that define cirrhosis originating from these disparate origins. We hypothesized that cirrhosis is not one disease and cirrhosis of different etiology may have differential clinical hepatic features.AIM To delineate the liver features between WD-associated cirrhosis and hepatitis Bassociated cirrhosis in the Chinese population.METHODS In this observational study, we reviewed the medical data of consecutive inpatients who had WD-associated cirrhosis or hepatitis B-associated cirrhosis from January 2010 to August 2018, and excluded patients who had carcinoma,severe heart or pulmonary diseases, or other liver diseases. According to the etiology of cirrhosis, patients were divided into two groups: WD-associated cirrhosis group(60 patients) and hepatitis B-associated cirrhosis group(56 patients). The liver fibrosis degree, liver function indices, and portal hypertension features of these patients were compared between the two groups.RESULTS No inter-group differences were observed in the diagnostic liver fibrosis markers,however, clinical features clearly defined the origin of cirrhosis. WD-associated cirrhosis patients(16-29 years) had lower levels of alanine transaminase,aspartate transaminase, and bilirubin, lower prothrombin time, lower incidence of hepatic encephalopathy, and lower portal vein diameter(P < 0.05), compared to cirrhosis resulting from hepatitis B in older patients(45-62 years). Importantly,they had decreased risks of progression from Child-Pugh grade A to B(odds ratio = 0.046, 95% confidence interval: 0.006-0.387, P = 0.005) and of ascites(odds ratio = 0.08, 95% confidence interval: 0.01-0.48, P = 0.005). Conversely, WDassociated cirrhosis patients had a higher risk of splenomegaly(odds ratio = 4.15,95% confidence interval: 1.38-12.45, P = 0.011).CONCLUSION WD-associated cirrhosis presents a highe展开更多

METHODS: Mutations of the ATP7B gene were sought by means of direct sequencing in 50 Eastern Chinese WD patients of Han ethnic origin. RESULTS: Two novel mutations, Asp96Gly and Asp196Glu, were first identified. We also compared the characterization of mutations in ATP7B with the clinical findings, and a significant correlation with hepatic manifestations between patients carrying the Arg778Leu mutation and those without was found. CONCLUSION: Gene sequencing analysis was shown to have a high detection rate and accuracy. It may become the first priority in screening of WD patients.展开更多

METHODS： We compared findings of patients presenting with ALF due to WD to those with ALF of other etiologies. RESULTS： Previously described criteria, such as low alkaline phosphatase activity, ratio of low alkaline phosphatase to total bilirubin or ratio of high aspartate arninotransferase （AST） to alanine arninotransferase （ALT）, failed to identify patients with ALF due to WD. There were significant differences in low ALT and AST activities （53 ± 43 vs 1982 ± 938, P 〈 0.0001 and 87 ± 44 vs 2756 ± 2941, P = 0.037, respectively）, low choline esterase activity （1.79 ± 1.2 vs 4.30 ± 1.2, P = 0.009）, high urine copper concentrations （93.4 ± 144.0 vs 3.5 ± 1.8, P = 0.001） and low hemoglobin （7.0 ± 2.2 vs 12.6 ± 1.8, P 〈 0.0001） in patients with ALF caused by WD as compared with other etiologies. Interestingly, 4 of 7 patients with ALF due to WD survived without liver transplantation. CONCLUSION： In ALF, these criteria can help establish a diagnosis of WD. Where applicable, slitlamp examination for presence of Kayser-Fleischer rings and liver biopsy for determination of hepatic copper concentration still remain important for the diagnosis of ALF due to WD. The need for liver transplantation should be evaluated carefully as the prognosis is not necessarily fatal.展开更多
