ABSTRACT
Objective@#We aimed, in our prospective study, to assess the predictive value of serum non-invasive and biochemical markers for clinical diagnosis of significant fibrosis (including early stages).@*Methods@#We measured sH2a levels in serum, comparing with routine liver function markers. We compared blindly pretreatment serum samples from a cohort of hepatitis B patients without non-alcoholic fatty liver disease(NAFLD), which had histological grades of liver fibrosis, with NAFLD individuals and CHB with NAFLD patients. Statistical analysis was by Student′s t test, and receiver-operating characteristic (ROC) curves were drawn.@*Results@#ROC curves showed that serum sH2a had greater diagnostic performance than routine liver function markers compared with histological grades of liver fibrosis(S0, S1-2, S3-4). ROC curves showed that using a sH2a cut-off point of 0.79 was with highest sensitivity as 63% and highest specificity as 80%. And sensitivity as 96.7% and specificity as 75.5% when using a sH2a cut-off point of 0.77.@*Conclusions@#sH2a has the potential to be a uniquely sensitive and specific novel marker for liver fibrosis and function.
ABSTRACT
Objective To diagnose the process of hepatic injury,a method of quantitating the concentration of sH2a subunit from asialoglycoprotein receptor (ASGPR) in serum by enzyme-linked immunosorbent assay was established and clinical evaluated.Methods 210 serum samples were collected in Suzhou Kowloon Hospital.Among them,70 subjects with cirrhosis,viral hepatitis and fatty liver disease were as hepatic injury group and 140 subjects of healthy and high fat,hemolysis,jaundice and with autoimmune disease were as control group.The serum sH2a of two group were measured by ELISA kit.The results of sH2a ELISA were analyzed by four table chi-square test and SPSS20.0 software.Results sH2a protein level in liver injury group and control group were 105.92+ 53.41 ng/ml and 69.25+27.45 ng/ml,respectively.The difference between the control group and the liver injury group was statistically significant (F=14.375,t=5.397,P=0.000).The sensitivity and specificity of the sH2a ELISA kit were 68.57％ (95％CI:56.37～79.15％) and 82.86％ (95％CI:75.58％～88.70％),and the total compliance rate was 78.10％ (95％CI:71.88％～83.49％) with KAPPA coefficient:0.510 6 (95％ CI:0.3877～0.6336).Conclusion SH2a serum ELISA kit with positive and negative coincidence rate between SH2a serum level and meet the clinical requirement,which could be used as new marker for diagnosis of heptieal injury related diseases.
