ObjectiveTo explore the predictive value of serum prothrombin induced by vitamin K absence-Ⅱ (PIVKA-Ⅱ) detection for the biological characteristics of hepatitis B virus (HBV)-associated hepatocellular carcinoma (HCC).MethodsThis retrospective study included 394 patients with HBV-related HCC who were newly diagnosed and treated with surgical resection in West China Hospital of Sichuan University between June 2017 and December 2018. Their clinical information such as tumor size, tumor number, tumor cell differentiation, presence of microvascular invasion (MVI), distant metastasis, and portal vein tumor thrombus was collected from the medical record. The laboratory test results of patients during diagnosis and before surgery were collected, including alpha-fetoprotein (AFP), PIVKA-Ⅱ, alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transferase (γ-GGT), etc., and the relationships between PIVKA-Ⅱ levels and tumor biological characteristics were analyzed. Non-normal continuous variables were presented as medium (lower quartile, upper quartile).ResultsCompared with the patients with low HCC serum PIVKA-Ⅱ levels (≤40 mAU/mL), patients with high serum PIVKA-Ⅱ levels (>40 mAU/mL) had larger tumor diameters [5.00 (3.00, 9.00) vs. 2.50 (1.63, 4.95) cm, P<0.001], more severe Barcelona Clinic Liver Cancer (BCLC) stage (P<0.001), and higher AFP [186.05 (6.86, 1 210.00) vs. 17.83 (4.33, 231.95) ng/mL, P<0.001], ALT [38.00 (26.00, 66.25) vs. 32.00 (22.00, 51.00) U/L, P=0.018], AST [42.00 (30.00, 76.00) vs. 34.00 (25.50, 48.25) U/L, P<0.001], and γ-GGT [71.00 (39.00, 165.50) vs. 55.50 (25.00, 93.00) U/L, P=0.005], and were more likely to form portal vein tumor thrombi (16.61% vs. 3.75%, P=0.003) and MVI (43.67% vs. 11.11%, P<0.001). In BCLC stage 0 HCC patients, the positive rate of PIVKA-Ⅱ was only 51.35%. Multivariate logistic regression analysis showed that PIVKA-Ⅱ>40 mAU/mL was an independent predictor of MVI [odds ratio=6.588, 95% confidence interval (CI) (1.645, 26.383), P=0.008]. The area under receiver operating characteristic curve of PIVKA-Ⅱ level predicting MVI was 0.761 [95%CI (0.693, 0.830)], with a sensitivity of 66.22% and a specificity of 79.06%.ConclusionIn HBV-related HCC patients, high PIVKA-Ⅱ is associated with the poor biological characteristics of tumor, and is an independent risk factor for tumor MVI.
Objective To systematically review the efficacy and safety of interferon based antiviral therapy for children with hepatitis B. Methods PubMed, EMbase, The Cochrane Library, WanFang Data and CNKI databases were searched to collect randomized controlled trials (RCTs) of interferon based antiviral therapy for children with hepatitis B from inception to December 2016. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by using RevMan 5.3 software. Results A total of 12 studies involving 723 patients were included. The results of meta-analysis showed that: follow-up <12 months, the virological response rate (RR=2.82, 95%CI 1.98 to 4.02, P<0.000 01), serum HBeAg clearance rate (RR=3.02, 95%CI 1.95 to 4.67,P<0.000 01) and ALT normalization rate (RR=1.42, 95%CI 1.19 to 1.70,P=0.000 1) were significantly higher in the interferon group than the control group. Follow-up >12 months, the virological response rate (RR=1.75, 95%CI 1.18 to 2.60, P=0.006) and serum HBeAg clearance rate (RR=2.17, 95%CI 1.28 to 3.65, P=0.004) were also significantly higher in the interferon group. Severe adverse effects were not reported in included studies. Conclusion Current evidence shows that higher virological response is found in HBV infected children with interferon treatment. Due to limited quality and quantity of the included studies, more high quality studies are needed to verify above conclusion.
ObjectiveTo detect the expression of indoleamine2, 3-dioxygenase (IDO) and HBV preS mRNA in HepG2 cells and its inhibitory effect on the proliferation of human peripheral blood lymphocyte. MethodsThe AdIDOEGFPpreS was transfected to human hepatocarcinoma cell line HepG2 and the specific fragment of IDO mRNA and HBV preS mRNA in these HepG2 cells were detected by RT-PCR. Then the transfected HepG2 cells were cocultured with human peripheral blood lymphocyte and the inhibitory effect of IDO on the proliferation of human peripheral blood lymphocyte was observed. ResultsThe IDO and HBV preS mRNA were successfully transferred to HepG2 cells, so the specific fragment of IDO and HBV preS mRNA could be found in the transfected HepG2 cells but not in the control group HepG2 cells by RT-PCR. Furthermore, the relative expression intensity of IDO and HBV preS were 1.27 and 1.18, respectively. When co-cultured with human peripheral blood lymphocyte, the counts per minute in the transfected HepG2 cells 〔(7 471±1 375) beats/min〕 was significantly less than that in the control group 〔(13 821±1 997) beats/min〕, Plt;0.001. ConclusionThe target gene IDO and HBV preS can be transferred and expressed in HepG2 cells successfully, which can obviously suppress the proliferation of human peripheral blood lymphocyte.
ObjectiveTo systematically review the efficacy and safety of interferon-alpha (IFN-α) combined with enticavir (ETV) for treatment-na?ve chronic hepatitis B (CHB) patients, so as to provide references for clinical practice. MethodsWe electronically searched databases including PubMed, EMbase, The Cochrane Library (Issue 7, 2015), Web of Science, WanFang Data, CNKI, CBM and VIP from inception to July 20th, 2015, to collect randomized controlled trials (RCTs) about IFN-α combined with ETV versus IFN-α or ETV monotherapy for treatment-na?ve CHB patients. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, meta-analysis was performed using RevMan 5.3 software. ResultsA total of 10 RCTs involving 964 patients were included. The results of meta-analysis showed that:For HBV-DNA loss rate, HBeAg loss rate and HBeAg seroconversion rate, there were no significant differences between the combination therapy group and the monotherapy group at 12-week of treatment, but the combination therapy group was significantly superior to the monotherapy group at 24-and 48-week of treatment except that there was no significant difference between the combination therapy group and the IFN-α monotherapy group in HBeAg seroconversion at 48-week of treatment. For rate of ALT normalization, the combination therapy group was superior to the IFN-α monotherapy group at 12-and 24-week of treatment, but there were no significant differences between the combination therapy group and the ETV monotherapy group at 12-, 24-, and 48-week of treatment. For safety, no pooled analysis was performed because different outcomes were reported by included studies. ConclusionIFN-α combined with ETV is superior to IFN-α or ETV monotherapy in decreasing viral load, and promoting HBeAg loss and HBeAg seroconversion for treatment-na?ve CHB patients, but the evidence of safety is insufficient. Due to the limited quantity and quality of included studies, the aforementioned conclusions still need to be further verified by conducting more large-scale, high quality RCTs.
Objective To assess the efficacy of telbivudine in the treatment of chronic hepatitis B (CHB). Methods Randomized controlled trials (RCTs) of telbivudine therapy vs. lamivudine therapy in both Chinese and English were retrieved from seven electronic databases with a cut-off date in February 2010, including PubMed, EMbase, VIP, CBM, CNKI, and The Cochrane library. The meta-analyses and evaluation on methodology quality were performed for the included studies. Results Two RCTs as Grade-A study were included. The meta-analyses showed that telbivudine was superior to lamivudine in aspects of therapeutic response (RR=1.28, 95%CI 1.10 to 1.48, P=0.001), ALT normalization (RR=1.12, 95%CI 1.01 to 1.23, P=0.02), and PCR-negative HBV DNA or below the lower limit (RR=1.44, 95%CI 1.36 to 1.53, Plt;0.000 01), primary treatment failure (OR=0.28, 95%CI 0.18, to 0.43, Plt;0.000 01), viral breakthrough (OR=0.38, 95%CI 0.32 to 0.47, Plt;0.000 01) and viral resistance (OR=0.44, 95%CI 0.36 to 0.55, Plt;0.000 01). Conclusion Based on the current clinical evidence, telbivudine demonstrates superiority in comparison with lamivudine on all direct measures of antiviral efficacy for CHB. Because of the short follow-up duration and the small sample size of the included studies, it is expected to further discuss the long-term efficacy.
Objective To evaluate the effectivenss of Chinese herbal retention enema in viral hepatitis patients. Methods Such databases as The Cochrane library, PubMed, EMbase, VIP, CNKI, CBM and WanFang Data were searched from the inception to December, 2011 to collect the randomized controlled trials (RCTs) about Chinese herbal retention enema in treating viral hepatitis, and the references of the included literature were also retrieved. Two reviewers independently screened the literature according to the inclusion and exclusion criteria, extracted the data, and evaluated and cross-checked the methodological quality. Then meta-analysis was conducted using RevMan 5.0 software. Results A total of 20 RCTs involving 1 735 patients were included. The subgroup analyses based on the length of intervention time showed that: a) after 2-week intervention: the overall effective rate of the Chinese herbal retention enema group was higher than that of the control group, with a significant difference (OR=3.19, 95%CI 1.87 to 5.44, Plt;0.000 1). Compared with the control group, the Chinese herbal retention enema group better promoted the recovery of liver function by more reduction of AST (MD= ?82.50, 95%CI ?145.66 to ?19.34, P=0.01), ALT (MD= ?44.78, 95%CI 65.90 to ?23.66, Plt;0.000 1) and TBIL (MD= ?37.51, 95%CI ?74.07 to ?0.95, Plt;0.0001). b) After 1-month intervention: The overall effective rate of the Chinese herbal retention enema group was higher than that of the control group, with a significant difference (OR=4.17, 95%CI 2.37 to 7.32, Plt;0.000 01). Compared with the control group, the Chinese herbal retention enema group better promoted the recovery of liver function by more reduction of AST (MD= ?17.86, 95%CI ?29.97 to ?5.76, P=0.004), ALT (MD= ?27.84, 95%CI ?42.45 to ?13.24, P=0.000 2), and TBIL (MD= ?54.15, 95%CI ?116.52 to ?8.23, P=0.09). Conclusion Chinese herbal retention enema can improve the overall effective rate for viral hepatitis patients, alleviate virus damage to liver cell and promote liver function recovery. The commonly used Chinese medicinals for enema are Radix et Rhizoma Rhei, Herba Artemisiae Capillaris, Salvia miltiorrhiza, and Radix Paeoniae Rubra.
