RESUMO
OBJECTIVES: Objective response rate (ORR) under mRECIST criteria after transarterial chemoembolization (TACE) is a well-perceived surrogate endpoint of overall survival (OS). However, its optimal time point remains controversial and may be influenced by tumor burden. We aim to investigate the surrogacy of initial/best ORR in relation to tumor burden. METHODS: A total of 1549 eligible treatment-naïve patients with unresectable hepatocellular carcinoma (HCC), Child-Pugh score ≤ 7, and performance status score ≤ 1 undergoing TACE between January 2010 and May 2016 from 17 academic hospitals were retrospectively analyzed. Based on "six-and-twelve" criteria, tumor burden was graded as low, intermediate, and high if the sum of the maximum tumor diameter and tumor number was ≤ 6, > 6 but ≤ 12, and > 12, respectively. RESULTS: Both initial and best ORRs interacted with tumor burden. Initial and best ORRs could equivalently predict and correlate with OS in low (adjusted HR, 2.55 and 2.95, respectively, both p < 0.001; R = 0.84, p = 0.035, and R = 0.97, p = 0.002, respectively) and intermediate strata (adjusted HR, 1.81 and 2.22, respectively, both p < 0.001; R = 0.74, p = 0.023, and R = 0.9, p = 0.002, respectively). For high strata, only best ORR exhibited qualified surrogacy (adjusted HR, 2.61, p < 0.001; R = 0.70, p = 0.035), whereas initial ORR was not significant (adjusted HR, 1.08, p = 0.357; R = 0.22, p = 0.54). CONCLUSIONS: ORR as surrogacy of OS is associated with tumor burden. For patients with low/intermediate tumor burden, initial ORR should be preferred in its early availability upon similar sensitivity, whereas for patients with high tumor burden, best ORR has optimal sensitivity. Timing of OR assessment should be tailored according to tumor burden. KEY POINTS: ⢠This is the first study utilizing individual patient data to comprehensively analyze the surrogacy of ORR with a long follow-up period. ⢠Optimal timing of ORR assessment for predicting survival should be tailored according to tumor burden. ⢠For patients with low and intermediate tumor burden, initial ORR is optimal for its timeliness upon similar sensitivity with best ORR. For patients with high tumor burden, best ORR has optimal sensitivity.

BACKGROUND & AIMS: Previous prognostic scores for transarterial chemoembolization (TACE) were mainly derived from real-world settings, which are beyond guideline recommendations. A robust model for outcome prediction and risk stratification of recommended TACE candidates is lacking. We aimed to develop an easy-to-use tool specifically for these patients. METHODS: Between January 2010 and May 2016, 1,604 treatment-naïve patients with unresectable hepatocellular carcinoma (HCC), Child-Pugh A5-B7 and performance status 0 undergoing TACE were included from 24 tertiary centres. Patients were randomly divided into training (nâ¯=â¯807) and validation (nâ¯=â¯797) cohorts. A prognostic model was developed and subsequently validated. Predictive performance and discrimination were further evaluated and compared with other prognostic models. RESULTS: The final presentation of the model was "linear predictorâ¯=â¯largest tumour diameter (cm)â¯+â¯tumour number", which consistently outperformed other currently available models in both training and validation datasets as well as in different subgroups. The thirtieth percentile and the third quartile of the linear predictor, namely 6 and 12, were further selected as cut-off values, leading to the "six-and-twelve" score which could divide patients into 3 strata with the sum of tumour size and number ≤6, >6 but ≤12, and >12 presenting significantly different median survival of 49.1 (95% CI 43.7-59.4) months, 32.0 (95% CI 29.9-37.5) months, and 15.8 (95% CI 14.1-17.7) months, respectively. CONCLUSIONS: The six-and-twelve score may prove an easy-to-use tool to stratify recommended TACE candidates (Barcelona Clinic Liver Cancer stage-A/B) and predict individual survival with favourable performance and discrimination. Moreover, the score could stratify these patients in clinical practice as well as help design clinical trials with comparable criteria involving these patients. Further external validation of the score is required. LAY SUMMARY: There is currently no prognostic model specifically developed for recommended or ideal transarterial chemoembolization (TACE) candidates with hepatocellular carcinoma, despite these patients being frequently identified as the best target population in pivotal randomized controlled trials. The six-and-twelve score provides patient survival prediction, especially in ideal candidates of TACE, outperforming other currently available models in both training and validation sets, as well as different subgroups. With cut-off values of 6 and 12, the score can stratify ideal TACE candidates into 3 strata with significantly different outcomes and may shed light on risk stratification of these patients in clinical practice as well as in clinical trials.

OBJECTIVE: Acute-on-chronic liver failure (ACLF) is an extreme condition after severe acute exacerbation of chronic hepatitis B; however, the underlying genetic factors involved in its onset and progression are currently unclear. DESIGN: We carried out a genome-wide association study among 399 HBV-related ACLFs (cases) and 401 asymptomatic HBV carriers (AsCs, as controls) without antiviral treatment. The initial findings were replicated in four independent case-control sets (a total of 901 ACLFs and 1686 AsCs). The roles of risk variants on clinical traits of ACLF were also analysed. RESULTS: Among 1300 ACLFs and 2087 AsCs, we identified rs3129859 at human leucocyte antigen (HLA) class II region (chromosome 6p21.32) associated with HBV-related ACLF (combined P dominant =2.64×10-20, OR=1.83). Analysis identiï¬ed HLA-DRB1*12:02 as the top susceptible HLA allele associated with ACLF (p=3.94×10-6, OR=2.05). The association of rs3129859 was robust in ACLF subgroups (ACLFs with liver cirrhosis, p=1.36×10-16; ACLFs without liver cirrhosis, p=1.52×10-7), and patients at low-replicative phase (p=6.36×10-11, OR=2.29) or HBV e antigen-negative chronic hepatitis B phase (p=1.51×10-14, OR=1.86). Clinical traits analysis in patients with ACLF showed that the risky rs3129859*C allele was also associated with prolonged prothrombin time, faster progression to ascites development and higher 28-day mortality. CONCLUSIONS: Our genome-wide association study identified HLA-DR as the major locus for susceptibility to HBV-related ACLF. Our findings highlight the importance of HLA class II restricted CD4+ T-cell pathway on the immunopathogenesis of HBV-related ACLF.

As a noninvasive marker, serum alanine aminotransferase (ALT) has limitations, because a large proportion of patients chronically infected with hepatitis B virus (HBV) suffer from severe hepatic necroinflammation, but have normal or mildly elevated ALT. In the present study, we aimed to investigate the potential value of serum Golgi protein 73 (GP73) in predicting significant hepatic necroinflamation among chronic HBV infected patients. A cohort of 497 chronic HBV infected patients was retrospectively recruited. Liver biopsy was performed in all patients and serum GP73 levels were measured by enzyme-linked immunosorbent assay. Serum GP73 increased in parallel with the increase in hepatic necroinflammatory activity grade (r = 0.682) and the stage of liver fibrosis (r = 0.539). The positive correlation of serum GP73 with the degree of hepatic necroinflammatory activity was statistically significant, while serum GP73 with the stage of liver fibrosis was weaker than that with hepatic necroinflammation. Furthermore, serum GP73 levels were significantly greater in patients with normal or mildly elevated ALT and significant hepatic necroinflammation (≥G2) than in patients with minimal to mild hepatic necroinflammation. The sensitivity and specificity of GP73 for the diagnosis of G2 hepatic necroinflammation was 42.35% and 95.0%, respectively, at a cut-off value of 88.38 ng/mL. When the cut-off value was set at 124.76 ng/mL, the sensitivity and specificity of GP73 for the diagnosis of G3 hepatic necroinflammation was 55.56% and 97.29%, respectively. These findings indicate that GP73 holds promise as an important candidate for diagnosing significant hepatic necroinflammation.

This study aimed to construct a non-invasive diagnostic nomogram based on high-frequency ultrasound and magnetic resonance imaging results for early liver cirrhosis patients with chronic hepatitis B (CHB) which cannot be detected by conventional non-invasive examination methods but can only be diagnosed through invasive liver puncture for pathological examination. 72 patients with CHB were enrolled in this prospective study, and divided into S4 stage of liver cirrhosis and S0-S3 stage of non-liver cirrhosis according to pathological findings. Binary logistic regression analysis was performed to identify independent predictors, and a diagnostic nomogram was constructed for CHB-related early cirrhosis. It was validated and calibrated by bootstrap self-extraction. Binary logistic regression analysis showed that age (OR 1.14, 95% CI (1.04-1.27)), right hepatic vein diameter (OR 0.43, 95% CI 0.23-0.82), presence or absence of nodules (OR 31.98, 95% CI 3.84-266.08), and hepatic parenchymal echogenicity grading (OR 12.82, 95% CI 2.12-77.51) were identified as independent predictive indicators. The nomogram based on the 4 factors above showed good performance, with a sensitivity and specificity of 90.70% and 89.66%, respectively. The area under the curve (AUC) of the prediction model was 0.96, and the predictive model showed better predictive performance than APRI score (AUC 0.57), FIB-4 score (AUC 0.64), INPR score (AUC 0.63), and LSM score (AUC 0.67). The calibration curve of the prediction model fit well with the ideal curve, and the decision curve analysis showed that the net benefit of the model was significant. The nomogram in this study can detect liver cirrhosis in most CHB patients without liver biopsy, providing a direct, fast, and accurate practical diagnostic tool for clinical doctors.

Background: Epilepsy is a chronic disease that can reduce the quality of life in children because it can cause memory loss, learning difficulties, mental and behavioral abnormalities, and social disorders. The purpose of this study was to explore the effect of the hospital-community-family linkage continuous nursing model in the nursing of children with epilepsy. Methods: Data for 136 children with epilepsy who were hospitalized in the neurology clinic or neurology ward of Wuxi Children's Hospital from January 2018 to January 2021 were retrospectively analyzed. According to the nursing mode after discharge, the children were divided into 65 cases in the observation group (hospital-community-family linkage continuous nursing model) and 71 cases in the control group (routine nursing model). The compliance with nursing, cognitive function, resilience, and quality of life of the two groups were compared before and after intervention, and the influencing factors of children's quality of life were analyzed. Results: The follow-up visit 6 months after discharge found that the scores for compliance, resilience, and quality of life in the observation group were significantly higher than those in the control group (P<0.05). The correlation analysis between quality of life, each child's general data, and the nursing model found that the total score of quality of life was correlated with incidence frequency, family per capita income, and the nursing model. Conclusions: The adoption of a hospital-community-family linkage continuous nursing model can improve the compliance, resilience, and quality of life of children with epilepsy.
RESUMO
INTRODUCTION: The benefits of combining transarterial chemoembolization (TACE) and sorafenib (TACE-S) over TACE alone for treatment of unresectable hepatocellular carcinoma (HCC) remain controversial. Yet, such populations are heterogeneous in terms of baseline characteristics. OBJECTIVE: To investigate the predictors of survival benefits from added sorafenib and identify the potential candidates for TACE-S. METHODS: This multicenter observational study was conducted in 17 Chinese tertiary hospitals for patients with unresectable, liver-confined HCC. Eligible patients with performance status score of ≤1 and Child-Pugh score of ≤7 were treated with TACE or TACE-S. Interactions between treatment and baseline variables were evaluated to find indicators for survival benefits, based on which the patients were stratified. Multivariate models adjusted for baseline characteristics or propensity score were used to compare overall survival (OS) and time to tumor progression (TTP). RESULTS: From January 2009 to December 2015, 1,719 consecutive patients received TACE (n = 1,406) or TACE-S (n = 313). Although TACE-S compared with TACE improved TTP (adjusted hazard ratio [HR] 0.75, p = 0.008), no difference in OS was observed (adjusted HR 0.87, p = 0.090). Nevertheless, the tumor burden (sum of maximum diameter of largest tumor [cm] and tumor number) and albumin-bilirubin (ALBI) score independently predicted the survival benefits from added sorafenib (interaction p< 0.001). For patients with either moderate tumor burden (7-13) or low ALBI score (no more than -2.8) defined as candidates, TACE-S prolonged OS (adjusted HR 0.73, p = 0.003) and TTP (adjusted HR 0.72, p = 0.014) compared to TACE alone, whereas its superiority disappeared in non-candidates. CONCLUSIONS: Not all unresectable HCC patients but those with moderate tumor burden or low ALBI score achieve survival benefits from TACE-S compared with TACE alone. Future randomized controlled trials focusing on the subset are warranted.
RESUMO
OBJECTIVE: To investigate the effect of lamivudine, interferon alpha and oxymatrine treatment for surviving hepatic failure patients with hepatitis B. METHODS: 200 hepatitis B patients, including 100 subacute or acute-on-chronic hepatic failure survivals (group A), and 100 chronic (group B, n=100) hepatic failure survivals, were enrolled in this study. Patients in group A received interferon alpha (n=35), lamivudine (n=33) , or combinational lamivudine and oxymatrine (n=32) therapy for six months; Patients in group B received lamivudine (n=49), or combinational lamivudine and oxymatrine (n=51) therapy for six months, respectively. After the treatment, all patients were followed-up for six months. RESULTS: At the end of follow-up, all patients in group A survived, while in group B three patients (6.1%) receiving lamivudine, and four (7.8%, P>0.05) receiving combinational therapy died; more than 90% of all survivals had their HBV DNA loss. The HBeAg/anti-HBe seroconversion rate in patients of group A treated with interferon alpha (9/17, 52.9%) was higher than that in patients treated with combinational lamivudine and matrine (5/16, 31.3%, P<0.05), which was higher than that in the patients treated with lamivudine alone (1/17, 5.9%, P<0.01), and the Knodell histological activity index score in patients treated with lamivudine (7.2+/-0.8, P<0.05) was lower than that in patients treated with interferon alpha (8.2+/-1.3, P<0.05), and the best efficacy was found in receiving combinational therapy (6.9+/-0.7, P<0.01); Lamivudine or lamivudine in combination with matrine significantly inhibited the intrahepatic inflammatory activities, but had no effect on the existing fibrosis in group B patients. CONCLUSION: Long term nucleotide analogues treatment may delay the progress of fibrosis in hepatitis B-induced hepatic failure survivals, and the administration of matrine in time may further enhance the anti-fibrotic effect of nucleotide analogues.

This study aimed to assess the feasibility of GP73 as a diagnostic marker for liver inflammation and fibrosis in chronic HBV patients with normal or slightly raised ALT (<2 ULN) and to develop models based on GP73 and other biochemical parameters to improve diagnostic accuracy. Serum GP73 levels were analyzed in 220 chronic HBV patients with normal or slightly raised ALT who underwent liver biopsy. The results showed that the area under the receiver operating characteristic (ROC) curve (AUC) was 0.806 for predicting significant liver inflammation (≥G2), while it was 0.742 for predicting significant fibrosis (≥S2). These results suggest that GP73 has higher diagnostic value for liver inflammation than liver fibrosis. Combining GP73, AST and ALB, as a diagnostic model for predicting significant liver inflammation, resulted in superior diagnostic performance over GP73 alone (AUC value increased from 0.806 to 0.854, z = 2.299, P = 0.021). By applying this diagnostic model, over 80% of chronic HBV patients with normal or slightly raised ALT will be correctly identified and hence avoid delay in diagnosis and treatment. In conclusion, GP73 would be an additional serum marker for predicting liver inflammation and fibrosis in chronic HBV patients with normal or slightly raised ALT.

Portal vein tumor thrombus (PVTT) in hepatocellular carcinoma (HCC) is a common entity. However, the prognosis of patients with hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT) is extremely poor. The current study reports a case of HCC with PVTT, including a description of the gross surgical pathology and discussion of the relevance of assessing the growth of the tumor thrombus to the outcome of this disease. This case suggests that destruction of the primary tumor and PVTT must be considered according to the growth characteristics and modality of PVTT. It also indicates that transcatheter arterial embolization may be a suitable strategy for palliative treatment of patients with advanced HCC with PVTT.
RESUMO
Ligation of splenic artery (LSA) is used for the treatment of liver cirrhosis with hypersplenism. However, hypersplenism is not significantly improved following LSA treatment in some cases, and there are few reports of retreatment of hypersplenism after LSA. We report the case of a 47-year-old man with liver cirrhosis and hypersplenism who underwent LSA treatment, but did not significantly improve. Laboratory tests revealed severe leukocytopenia and thrombocytopenia. Celiac computed tomography arteriogram and digital subtraction angiography revealed two compensatory arteries connected to the hilar splenic artery from the left gastro-epiploic artery and from the dorsal pancreatic artery. Partial splenic embolization (PSE) was performed through the compensatory arteries. As a result, the patient achieved partial splenic ischemic infarction, and white blood cell and platelet counts rose and remained in the normal range. PSE is an effective therapeutic modality for the retreatment of hypersplenism when other modalities have failed.

Alanine aminotransferase (ALT) is the most commonly used marker of liver injury, but normal ALT levels are seen in a proportion of chronic hepatitis B virus (HBV)-infected patients with severe liver injury. Golgi protein 73 (GP73) is a promising alternative marker of liver injury. This study assessed the relation between GP73 levels and liver disease severity, monitored the kinetic changes in GP73 levels in chronic HBV patients receiving entecavir (ETV) therapy, and investigated the potential diagnostic and prognostic values of serum GP73 as a new liver injury biomarker in chronic HBV infections. This study enrolled 1150 patients with chronic HBV infections, 200 of whom were retrospectively enrolled in this study after receiving 1 year of ETV treatment. GP73 expression in liver tissue was detected by immunohistochemistry. GP73 levels in single or serial serum samples were measured by enzyme-linked immunosorbent assay. Immunohistochemical analysis indicated that GP73 protein expression in the liver increased progressively with pathologic progression from nonexistent or mild hepatitis to severe hepatitis and cirrhosis during chronic HBV infection. Serum GP73 levels were positively correlated with the disease severity of chronic HBV infections (râ=â0.58, Pâ<â0.001). In patients with normal ALT levels, serum GP73 concentrations were significantly higher in patients with prominent hepatic inflammatory injury and fibrosis than in patients without hepatic inflammatory injury or fibrosis. Serum GP73 concentrations and GP73 protein expression were decreased in the liver tissues of patients whose ALT levels normalized after 1 year of ETV antiviral therapy. Changes in serum GP73 levels were closely associated with changes in liver injury severity, and, therefore, GP73 may be an effective new liver inflammatory injury biomarker, and could be useful for monitoring the prognosis of chronic HBV infectious patients with normal ALT levels.

The present study was designed to assess the correlation between serum Golgi protein 73 (GP73) and liver pathological grading and staging in patients with chronic hepatitis B (CHB). Two hundred and fiftythree patients with chronic hepatitis B virus (HBV) infections were enrolled in the present study. All patients received a serum GP73 test, and 91 CHB patients underwent liver biopsy. GP73 expression in liver tissue was assessed by immunohistochemical analysis. The results indicated that serum GP73 levels were positively correlated with disease progression in patients with chronic HBV infection (r=0.677). There was no significant difference in serum GP73 levels between hepatitis B e antigenpositive and negative patients (P>0.05). There were also no significant differences in serum GP73 levels among specimens with varying HBV DNA contents (P>0.05). Serum GP73 levels were positively correlated with increased liver pathological grading (r=0.737) and staging (r=0.692), and immunohistochemical analysis indicated that GP73 protein expression increased concurrently with liver pathological grading and staging. In conclusion, serum GP73 was found to be correlated with liver pathological grading and staging in patients with CHB, and may be an effective indicator for the evaluation of disease progression. However, serum GP73 levels were not associated with HBV replication.

Dendritic cells (DCs) are multifunctional cells that initiate adaptive immune responses. Patients with chronic hepatitis B virus (HBV) infection have reduced numbers of DCs which may be functionally impaired, a defect that may contribute to viral persistence. Autologous DC-based immunotherapy is considered to be a treatment option for chronic HBV infection (CHB). We evaluated the therapeutic efficacy of HBV-pulsed DCs in combination with the antiviral drug entecavir in patients with CHB. Eighty patients were divided into four groups: HBV-pulsed DCs only, HBV-pulsed DCs plus entecavir, entecavir only, and an untreated control group. Patients on combination therapy exhibited greater antiviral responses than patients on either monotherapy. The combination of HBV-pulsed DCs and entecavir resulted in the largest reduction in serum viral DNA levels and the highest percentage of virologic response. In addition, combination therapy resulted in viral e antigen (HBeAg) loss and seroconversion. These results suggest that the combination of HBV-pulsed autologous DCs and entecavir could be therapeutically advantageous for patients with CHB.

AIM: To assess the efficacy and safety of bone marrow-derived mesenchymal stem cell (BM-MSC) in the treatment of decompensated liver cirrhosis. METHODS: The search terms "bone marrow stem cell" "chronic liver disease" "transfusion" and "injection" were used in the Cochrane Library, Med-Line (Pub-Med) and Embase without any limitations with respect to publication date or language. Journals were also hand-searched and experts in the field were contacted. The studies which used BM-MSC in the treatment of any chronic liver disease were included. Comprehensive Review Manager and Meta-Analyst software were used for statistical analysis. Publication bias was evaluated using Begg's test. RESULTS: Out of 78 studies identified, five studies were included in the final analysis. The studies were conducted in China, Iran, Egypt and Brazil. Analysis of pooled data of two controlled studies by Review Manager showed that the mean decline in scores for the model for end-stage liver disease (MELD) was -1.23 [95%CI: -2.45-(-0.01)], -1.87 [95%CI: -3.16-(-0.58)], -2.01 [95%CI: -3.35-(-0.68)] at 2, 4 and 24 wk, respectively after transfusion. Meta-analysis of the 5 studies showed that the mean improvement in albumin levels was -0.28, 2.60, 5.28, 4.39 g/L at the end of 8, 16, 24, and 48 wk, respectively, after transfusion. MELD scores, alanine aminotransferase, total bilirubin levels and prothrombin times improved to some extent. BM-MSC injections resulted in no serious adverse events or complications. CONCLUSION: BM-MSC infusion in the treatment of decompensated liver cirrhosis improved liver function. At the end of year 1, there were no serious side effects or complications.

OBJECTIVE: To evaluate the effect of autologous bone marrow-derived stem cell (BMSCs) transplantation in the treatment of liver failure and decompensated hepatic cirrhosis. METHODS: Bone marrow was harvested (65-95 ml) from 24 patients in the transplantation group. The BMSCs were isolated and infused into liver or spleen of patients via hepatic or splenic artery. At different time points after the transplantation, the patients' liver function and prothrombin time (PT) were evaluated, and the survival rate and symptoms of the patients were recorded. RESULTS: All the serum biochemical indexes remained stable 2 weeks after the transplantation, and at 4 weeks after transplantation, albumin level increased significantly in comparison with the preoperative level (P<0.05). At 12 weeks, the albumin level further increased (P<0.01) along with Pre-ALB (P<0.01), while total bilirubin, tolal bile acid, PT and fibrinogen were all significantly lowered (P<0.05), and globulin, ALT, and AST remained unchanged (P>0.05). One week after the transplantation, improved appetite was observed in 22 cases (91.67%), and 21 cases (87.5%) showed better physical strength; at 2 weeks, hepatic face improved in 15 cases (62.5%), and spider telangiectasia was significantly reduced in one case; at 12 weeks, the survival rate of the patients was 62.5%, and 9 died or gave up treatment due to chronic liver failure complicated by spontaneous bacterial peritonitis, hepatorenal syndrome, or DIC. No complications associated with the transplantation occurred in these patients. CONCLUSION: BMSC transplantation can significantly improve the liver function of patients with terminal liver disease with good safety and effectiveness.
