The clinical profiles of primary biliary cirrhosis with a suboptimal biochemical response to ursodeoxycholic acid / 中华肝脏病杂志

To observe the characteristics of primary biliary cirrhosis (PBC) with a suboptimal biochemical response to ursodeoxycholic acid. A total of 38 Chinse PBC patients (5 male patients, 33 female patients, average age 55 years old) with treatment of ursodeoxycholic acid in our hospital from January 1999 to January 2009 were erolled and studied retrospectively. 17 suboptimal biochemical responders mainly presented with liver diseases related symptoms including jaundice (41.1%), fatigue, anorexia (23.5%), edema and abdominal distension (11.7%). 21 good biochemical responders mainly presented with abnormal liver function tests without symptoms. The suboptimal biochemical responders had significantly higher baseline levels of total serum bilirubin, alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, immunoglobulin G and globulin as compared to the good biochemical responsers. There were no differences in gender, age and the dose of UDCA. PBC patients with liver diseases related symptoms, marked abnormal liver tests and characteristics of autoimmune hepatitis may have a suboptimal biochemical response to ursodeoxycholic acid treatment.

An ultrasonic scoring system for assessing the severity of hepatic fibrosis in patients with chronic hepatitis B / 中华肝脏病杂志

<p><b>OBJECTIVE</b>To discuss the diagnostic value of an ultrasonic assessing system for detecting the severity of hepatic fibrosis in patients with chronic hepatitis B (CHB).</p><p><b>METHODS</b>Ultrasonographic variables were analyzed in 110 CHB patients. An ultrasonic semi-quantitative scoring system using seven ultrasonic morphologic parameters, a Fisher discriminating function and three quantitative ultrasonic parameters was developed. The performance of these methods was also studied and compared.</p><p><b>RESULTS</b>The areas under the curve of the scoring system for different liver fibrosis stages were >or= S2: 0.946, >or= S3: 0.914, and S4: 0.915. The total score was well correlated with the histological stage of fibrosis (r=0.824, P < 0.001). There was a significant difference between the stages of fibrosis. The accuracy of the Fisher discriminating function for identifying three study endpoints was 76.5%, 78.2% and 67.3%. Combining the ultrasonic scoring system and the discriminating function, the specificity was 85%-90% and the accuracy was 77%-84%.</p><p><b>CONCLUSION</b>Our ultrasonic semi-quantitative scoring system is a noninvasive method for quantitating liver fibrosis. If it is used together with a discriminating function, the accuracy of diagnosing liver fibrosis can be significantly increased.</p>

Relationship between serum HBV DNA levels and hepatic fibrosis markers in chronic hepatitis B / 中华实验和临床病毒学杂志

<p><b>OBJECTIVE</b>To study the relationship between serum HBV DNA levels and hepatic fibrosis markers in chronic hepatitis B.</p><p><b>METHODS</b>One hundred and fifty-seven patients with chronic hepatitis B were included in the study, 49 patients among them were diagnosed as early cirrhosis by liver biopsy. Serum HBV DNA levels were determined using fluorescent quantitative PCR, and serum hepatic fibrosis markers including hyaluronic acid (HA), laminin (LN), amino terminal propeptide of type III precollagen (P III P) and type IV collagen (IV-C) were determined by radioimmunity assay. The relationship between serum HBV DNA levels and hepatic fibrosis markers were analyzed. Serum HBV DNA levels and hepatic fibrosis markers of 49 patients with early cirrhosis were compared with those of 108 non-cirrhotic patients.</p><p><b>RESULTS</b>There was no significant relationship between serum HBV DNA levels and hepatic fibrosis markers in chronic hepatitis B (P>0.05). Patients with early cirrhosis had much higher hepatic fibrosis markers together with lower HBV DNA levels than non-cirrhotic patients (P<0.05).</p><p><b>CONCLUSIONS</b>There were no significant relationship between serum HBV DNA levels and hepatic fibrosis markers in patients with chronic hepatitis B.</p>

Clinical features of 30 cases of amyloidosis / 中华肝脏病杂志

<p><b>OBJECTIVE</b>Clinical features of 30 cases of amyloidosis, a rare disease in China, were analyzed in order to improve the recognition of the disease here.</p><p><b>METHODS</b>30 cases of biopsy-proven amyloidosis, admitted to Beijing Friendship Hospital from July 1980 to December 2003 were retrospectively reviewed.</p><p><b>RESULTS</b>12 of the 30 cases were systemic amyloidosis. Among them 9 were primary amyloidosis, 1 secondary amyloidosis and 2 familial amyloid polyneuropathy. The other 18 cases were localized amyloidosis. Males (17) were more than females (13). In the 12 primary amyloidosis patients, kidney (75.00%), liver (58.33%), peripheral nervous system (58.33%) and heart (50.00%) were most commonly involved. Nonspecific symptoms such as fatigue, weight loss, hepatomegaly, limb numbness, edema and heavy albuminuria were the most common clinical manifestations. Localized amyloidosis involved only one organ, such as skin, alimentary tract and nasopharynx without evidences of a systemic disease. Excision of the localized amyloid deposits was performed in 13 cases.</p><p><b>CONCLUSION</b>Systemic amyloidosis usually involves multiple organs and systems, leading to highly variable clinical manifestations. An increase in the vigilance of the awareness of this disease among clinicians will improve the possibilities for its diagnosis.</p>

A discussion of standardization for prothrombin time in patients with advanced liver diseases / 中华肝脏病杂志

<p><b>OBJECTIVE</b>To determine which expression mode of prothrombin time (PT) might achieve PT standardization in patients with advanced liver diseases.</p><p><b>METHODS</b>PT was measured with six thromboplastins with different ISI values in 16 severe chronic hepatitis patients, 50 decompensated liver cirrhosis patients and 30 patients on oral anticoagulation therapy. The results were expressed in PT (second), PTA (%), PTR and INR.</p><p><b>RESULTS</b>In chronic hepatitis patients, the means of the six group's PTAs ranged from 24% to 34%, while their upper limits ranged from 47% to 61%. The means of the INRs ranged from 2.55 to 5.13, while their upper limits ranged from 4.65 to 12.77. Through one-way ANOVA of repeated measures, PPTA (0.489) was > PINR (0.120). In patients with liver cirrhosis, the means of the PTA in six groups ranged from 50% to 59%, while their upper limits ranged from 82% to 90%. The means of the INR ranged from 1.40 to 1.80, while their upper limits ranged from 1.97 to 3.69. Through one-way ANOVA of repeated measures, PPTA (0.102) was > PINR (0.01). In patients on oral coagulation therapy, the means of PTA ranged from 26% to 37%, while their upper limits ranged from 39% to 49%. The means of INR ranged from 2.35 to 2.66, while their upper limits ranged from 3.16 to 4.26. Through one-way ANOVA of repeated measures, PPTA (0.01) was less than PINR (0.102). The correlation between the results detected by Neoplastine and by other reagents were analyzed. They correlated well with each other when PTA was used as the expression mode of PT in patients with advanced liver disease. But in patients on oral anticoagulation therapy, when only the INR was used as the expression mode of PT, the correlation was well with each other.</p><p><b>CONCLUSION</b>The use of INR provides inadequate standardization. Only when the PT is expressed in PTA, then it may provide a standardization mode in patients with advanced liver diseases.</p>
