Objective:To study the virological and serological indicators before treatment and 24 weeks after treatment to predict the partial virological response (PVR) of 48-week entecavir (ETV) treatment, and formulate early clinical adjustment treatment plans for HBeAg-positive CHB patients.Methods:HBeAg-positive CHB-na?ve patients diagnosed in the Department of Infectious Diseases, Shengjing Hospital, China Medical University, who were treated with oral ETV monotherapy from January 2018 were enrolled. The groups were divided according to the test results of HBV DNA at 48 weeks. Among them, HBV DNA < 20 IU/ml was the complete viral response (CVR) group, and HBV DNA ≥ 20 IU/ml was the PVR group. The virological and serological indexes of the two groups before treatment and 24 weeks after treatment were compared. ROC curve univariate analysis and multivariate logistic regression were performed to find out the early predictors of PVR in HBeAg-positive CHB patients receiving ETV therapy for 48 weeks.Results:As of July 2020, a total of 90 cases had completed 48 weeks of treatment, including 50 cases of CVR (55.56%) and 40 cases of PVR (44.44%). Before treatment and at 24 weeks of treatment, HBsAg, HBeAg and HBV DNA in the PVR group were significantly higher than those in the CVR group ( P < 0.001). Univariate analysis showed that HBV DNA quantification (AUC = 0.961, P < 0.001, PPV = 97.06%, NPV = 87.50%) and HBeAg quantification (AUC = 0.883, P < 0.001, PPV = 90.63%, NPV = 81.03%) had higher predictive value at 24 weeks of treatment. Multivariate analysis showed that HBeAg > 1.952 log 10 S/CO ( OR = 3.177, 95% CI: 1.261 ~ 8.267, P = 0.018) and HBV DNA > 2.205 log 10 IU / ml ( OR = 43.197, 95% CI: 6.858 ~ 272.069, P < 0.001) were independent predictors of PVR at 24 weeks of treatment, and their combination had the best predictive effect. Conclusion:In HBeAg-positive CHB patients receiving ETV treatment for 48 weeks, HBV DNA combined with HBeAg quantification can be an early predictor of PVR at 24 weeks. Additionally, patients with both HBV DNA and HBeAg > 2 log 10 at 24 weeks of treatment must wait 48 weeks to obtain CVR, so it is recommended that treatment strategies should be adjusted at this time.

Objective: To explore the difference of liver inflammation and fibrosis in patients with chronic hepatitis B virus (HBV) infection and chronic hepatitis C virus (HCV) infection, and to investigate the relationship between hepatic pathology and alanine aminotransferase (ALT). Methods: 57 patients with chronic HCV infection and 346 patients with chronic HBV infection who were hospitalized at Shengjing Hospital of China Medical University from January 2012 to September 2016 were enrolled. In chronic HBV infection, including 88 cases whose ALT were more than two times of upper limited of normal (ALT≥2×ULN) and 258 cases whose ALT were less than two times of upper limited of normal (ALT < 2×ULN).All the patients were underwent liver biopsy. Chronic HBV infection (ALT≥2×ULN and ALT < 2×ULN) and chronic HCV infection were compared respectively. Statistical analyses were performed using a Univariate χ²-test and Mann–Whitney U test for comparison. Correlations between variables were analyzed using Spearman's rank correlation. Results: In chronic HBV infection group, 169 cases (48.8%) had inflammation grade≥2 (G≥2), 98 cases (28.3%) had fibrosis stage≥2 (S≥2), 81 cases (23.4%) with G≥2 and S≥2.In the ALT < 2×ULN group, there were 109 cases (42.2%) with G≥2, 62 cases (24%) with S≥2, 49 cases (19%) with G≥2 and S≥2. In the ALT≥2×ULN group, 60 cases (68.2%) with G≥2, 35 cases (39.8%) with S≥2, 31 cases (35.2%) with G≥2 and S≥2. The grade of inflammation and fibrosis have significantly different between ALT≥2×ULN group and ALT < 2×ULN group (χ² = 17.66, χ² = 8.06, P < 0.01). In chronic HCV infection group, 47 cases (82.5%) with G≥2, 20 cases (35.1%) with S≥2, 20 cases (35.1%) with G≥2 and S≥2. ALT had no correlation with inflammation and fibrosis (P > 0.05). The grade of inflammation was significantly different between chronic HCV infection and chronic HBV infection whose ALT < 2×ULN (χ² = 30.19, P < 0.01) but the fibrosis have no difference (χ² = 2.96, P > 0.05). Compared with chronic HBV infection whose ALT≥2×ULN, both inflammation and fibrosis had no significantly different (χ² = 3.65, χ² = 0.32, P > 0.05 respectively). Conclusion In chronic HBV infection whose ALT < 2×ULN, about 30%-40% liver tissue with significant necroinflammation and /or fibrosis. About 80% chronic HCV infection with significant necroinflammation, and the grade of inflammation has no correlation with ALT. The grade of inflammation has significantly different between chronic HCV infection group and chronic HBV infection group whose ALT < 2×ULN.

Due to the difference in infection time and immune clearance ability, patients with chronic hepatitis B virus (HBV) infection may appear as virus carrier or chronic active hepatitis. Alanine aminotransferase (ALT) is the most sensitive biomarkers for evaluating liver inflammation. Current anti-HBV drugs, nucleoside analogues (NAs) and peginterferon α, can only achieve satisfactory results when liver inflammation is active. Therefore, international authoritative guidelines recommend HBV DNA positive and ALT > 2-fold the upper limit of normal (2×ULN) as indications for treatment. However, many studies have shown that some chronic HBV infected patients with normal ALT have insidious progression to liver cirrhosis or liver failure, because of not initiating antiviral therapy in time. Hence, the disease assessment and initiation indication for treatment have received more and more attention and become a hot topic in clinical research for chronic HBV infected patients with normal ALT.

Objective:To analyze, explore and evaluate the clinical characteristics, abnormal thyroid function and follow-up of anti-hyperthyroidism treatment mode in patients with hyperthyroidism (commonly abbreviated as HT) combined with liver injury.Methods:The clinical data of patients with hyperthyroidism combined with liver injury were retrospectively analyzed, and then patients were divided into treated and untreated group according to whether they received anti-hyperthyroidism treatment before the consultation. Patients’ thyroid and liver function test indicators at the time of treatment were analyzed to determine the main cause of liver injury. The characteristics of liver injury were analyzed in the treatment group. Patients with severe thyroid toxicity and hyperthyroidism combined with liver injury were followed-up with anti-hyperthyroid therapy, mainly low-dose methimazole (MMI) and radioactive iodine therapy to evaluate its efficacy and safety. The comparison between data groups was performed by t-test, rank sum test and χ2 test. Results:Among the 43 cases with hyperthyroidism combined with liver injury, 19 were males and 24 were females, aged 49.0 ± 14.6 years-old; 16 cases (16/43, 37.21%) aged 40 to≤60 years- old, and 15 cases (15/43, 34.88%) aged > 60 years-old. There were 22 untreated cases (untreated group, accounting for 51.16%), and 21 treated cases with anti-hyperthyroidism (treatment group, accounting for 48.84%) at the time of consultation. Thyroid function indicators (FT3, FT4, TSH) and liver function indicators (alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, γ-glutamyltransferase, total bilirubin) of the two groups were compared, and the difference was not statistically significant ( P > 0.05). The order of liver injury from mild to severe in patients with different treatment options were: methimazole (MMI) < propylthiouracil < radioactive iodine
