Objective: To explore the clinical value of von Willebrand Factor (vWF) and VITRO score (vWF:Ag/platelet count) in assessing disease progression in patients with HBV infection. Methods: Randomly collect relevant clinical data of 308 patients with HBV infection (including 154 cases of chronic hepatitis B, 66 cases of hepatitis B cirrhosis in compensatory period, 88 cases of hepatitis B cirrhosis in decompensated period) from December 1, 2018 to January 5, 2021 in the Second Affiliated Hospital of Chongqing Medical University. The vWF values are measured by a uniform optical method, and all data are included using a uniform standard. Analyze the difference and significance of plasma vWF level and VITRO score in chronic hepatitis B, hepatitis B cirrhosis in the compensatory phase and decompensated phase. Results: The plasma vWF level and VITRO score of the chronic hepatitis B group were (139.47±76.44) and (0.86±0.8), respectively, and the hepatitis B cirrhosis compensated group was (164.95±67.12 and 1.44±1.14), respectively. Hepatitis cirrhosis decompensated group were (317.48±103.32 and 6.81±4.98), respectively; plasma vWF level and VITRO score increased with the progression of HBV infection, and the difference was statistically significant (F=133.669,P=0.000F=137.598,P=0.000).The plasma vWF level and VITRO score in patients with hepatitis B cirrhosis were (185.65±85.07 and 2.3±2.37) in the Child-Pugh A group, (304.74±105.81 and 6.37±5.19) in the B grade group, and (369.48±73.238.28±5.38) in the C grade group; plasma vWF level and VITRO score in patients with hepatitis B cirrhosis increased with the increase of Child-Pugh grade, and the difference was statistically significant (F=60.236, P=0.000F=32.854, P=0.000). The area under the curve (AUC) of plasma vWF level and VITRO score for diagnosing the decompensated stage of hepatitis B cirrhosis were 0.897 [95% confidence interval (CI): 0.855-0.940, P＜0.01], 0.949 [95% CI: 0.916-0.982, P＜0.01). When the vWF level and VITRO score were taken as cut-off values of 238.5% and 1.65, respectively, the sensitivity of diagnosing the decompensated stage of hepatitis B cirrhosis was 79.5% and 94.3%, the specificity was 92.3% and 87.7%, and the positive predictive value was 80.5% and 94.3%, the negative predictive value was 91.9% and 97.5%, and the diagnostic accuracy was 88.6% and 89.3%. Among the patients with decompensated hepatitis B cirrhosis, the level of vWF in the group with gastrointestinal bleeding (367.24±68.29)% was significantly higher than that in the group without gastrointestinal bleeding (286.15±109.69)%, and the difference was statistically significant (P＜0.001) The VITRO score of the group with gastrointestinal bleeding (9.12±5.4) was significantly higher than that of the group without gastrointestinal bleeding (5.36±4.13), and the difference was statistically significant (P＜0.01). The vWF level in the spontaneous peritonitis group was (341.73±87.92)% higher than that in the non-spontaneous peritonitis group (296.32±111.74)%, and the difference was statistically significant (P＜0.05). There was no statistical difference in VITRO score between the two groups. significance. Conclusion: Plasma vWF level and VITRO score can evaluate the progression of liver disease and the degree of decompensation of liver cirrhosis in patients with HBV infection, and have a predictive effect on various complications after decompensation of liver cirrhosis, and have certain guiding significance for early intervention measures.

Assessment of the factors associated with insulin resistance in patients with chronic hepatitis B infection / 中华肝脏病杂志

<p><b>OBJECTIVE</b>To investigate the factors associated with insulin resistance (IR) in patients with chronic hepatitis B virus (HBV) infection.</p><p><b>METHODS</b>Sixty-eight patients with mild chronic hepatitis B (MCHB) caused by HBV were recruited for study. Sixty-seven healthy individuals with no hepatitis virus infections and normal liver function were enrolled as controls. Demographic, anthropometric, clinical, and blood biochemical parameters were compared between the two groups. IR was determined by the homeostasis model assessment (HOMA-IR). The MCHB group was further divided into patients with IR (HOMA-IR: > 2.7) and patients without IR (HOMA-IR: less than 2.7). Demographic, anthropometric, clinical, and blood biochemical parameters were compared between the two sub-groups. Finally, the potential factors associated with IR were evaluated.</p><p><b>RESULTS</b>Compared to the healthy controls, the MCHB patients had significantly higher serum insulin (Z = -5.451, P less than 0.01), alanine aminotransferase (ALT) (Z = -8.211, P less than 0.01) and HOMA-IR (Z = -5.631, P less than 0.01). IR was detected in 44.12% (30/68) of the MCHB patients. The levels of ALT and body mass index (BMI) were significantly different between the MCHB patients with IR and without IR (t = -2.358, and t = -3.566, P less than 0.05). There was a significant correlation between BMI, ALT, and HOMA-IR in the MCHB patients (r = 0.374, r = 0.282, P less than 0.05), but not with the HBV DNA loads (r = 0.015, P = 0.904). Binary logistic regression analysis indicated that BMI [Exp(B): 1.859, P less than 0.01] and ALT [Exp(B): 1.022, P less than 0.05] were independent risk factors of IR in MCHB.</p><p><b>CONCLUSION</b>There is a high prevalence of insulin resistance in patients with mild hepatitis caused by chronic HBV infection. In these patients, IR is correlated with abnormal liver function and BMI, and not HBV load.</p>

Effect of HBV on the expression of SREBP in the hepatocyte of chronic hepatitis B patients combined with hepatic fatty change / 中华肝脏病杂志

To investigate the effect of HBV on the expression of Sterol regulatory element binding proteins( SREBP ) in the hepatocyte of patients with chronic hepatitis B (CHB) combined with hepatic fatty change. 55 cases diagnosed as CHB combined with hepatic fatty change in our department were selected and liver biopsies were carried out. The patients were dividied into 3 groups, group A: HBV DNA is less than or equal to 1000 copies/ml(15 cases), group B: 1000 copies/ml less than HBV DNA less than 100000 copies/ml (18 cases) and group C: HBV DNA is more than or equal to 100000 copies/ml (22 cases). 10 patients with HBV DNA in less than or equal to 1000 copies/ml after antiviral therapy with Nucleoside analogues were seen as group C1 (before treatment) and group C2 (after treatment) respectively; 12 patients with HBV DNA is more than or equal to 100000 copies/ml after antiviral therapy were classified as group C3 (before treatment) and group C4 (after treatment). Lipid droplets in the hepatic tissue were observed with oil red staining. Real time PCR were performed to detect the expressions of SREBP-1c and SREBP-2 mRNA in the liver. The protein expressions of SREBP-1c and SREBP-2 were detected with immunohistochemistry staining. Statistic data were analysed with SPSS11.5 software. (1) Red integrated optical densities (IOD) reflected by lipid drops in group A, B and C are 1004.27+/-218.63, 1937.01+/-401.47 and 4133.79+/-389.28 respectively, the degree of oil red O in each group was different (F = 385.69, P is less than to 0.01), which is increased as HBV DNA load increasing; Red IOD in group C1, C2 and C3, C4 are 4020.84+/-326.64, 1012.02+/-244.89, 4189.18+/-329.21 and 4121.76+/-304.09 respectively. Compared with group C1, the degree of oil red O in group C2 is decreased and the difference is statistically significant (t = 22.55, P is less than to 0.01); However, the difference of the degree of oil red O between group C4 and C3 is not statistically significant. (2) Compared with group A, the expressions of SREBP-1c mRNA in group B and C are raised by 1.218+/-0.130 and 1.798+/-0.118 times respectively, among group A, B, C, the expressions of SREBP-1c mRNA are statistically significant different ( F = 297.47, P is less than to 0.01). The expressions of SREBP-2 mRNA in group B and C are decreased by 0.956+/-0.118 and 0.972+/-0.153 times as compared to group A. However, the difference of SREBP-2 mRNA expression among the 3 groups is not statistically significant ( F = 0.568, P is more than to 0.05). Compared with group C1, SREBP-1c mRNA in group C2 is decreased by 0.714+/-0.081 folds (t=11.224, P is less than to 0.01), while SREBP-2 mRNA in group C2 is raised by1.034+/-0.155 times(t=0.692, P is more than to 0.05). SREBP-1c mRNA and SREBP-2 mRNA in group C4 are raised by 1.012+/-0.206 times and decreased by 0.998+/-0.183 times as compared to group C3 without difference found (t=0.196 or 0.031, P is more than to 0.05). (3) the expressions of SREBP-1c protein in group A, B and C are 36257.21+/-5709.79, 50413.47+/-4989.28 and 71025.83+/-6047.13 respectively, and the difference is statistically significant among the 3 groups (F = 178.26, P is less than to 0.01); the expressions of SREBP-2 protein in group A, B and C are 32913.52+/-3951.21, 32625.91+/-4025.06 and 34173.44+/-5316.25 respectively, but the difference is not statistically significant among the 3 groups ( F = 0.562, P is more than to 0.05), SREBP-1c protein levels in group C1, C2, C3, C4 are 69832.16+/-4941.36, 48735.47+/-5471.41, 70871.69+/-5083.14 and 68913.32+/-5343.22 respectively, the difference of SREBP-1c protein levels between group C1 and C2 is statistically significant (t=10.260, P is less than to 0.01); while the difference between group C3 and group C4 is not statistically significant(t=1.558, P is more than to 0.05). The expressions of SREBP-2 protein in group C1, C2, C3 and C4 are 33 980.21+/-4081.80, 34011.50+/-3859.27, 33610.12+/-4761.10 and 32915.66+/-5023.61 respectively, the difference of SREBP-2 protein levels in group C1 and group C2 is not statistically significant (t=0.038, P is more than to 0.05) and same result exists between group C3 and group C4 (t=0.459, P is more than to 0.05). HBV DNA may participate in the hepatic steatosis formation through interfering with the SREBP-1c expression.
