RESUMO
BACKGROUND: Transient elastography (FibroScan) is a new and non-invasive test, which has been widely recommended by the guidelines of chronic hepatitis B virus (HBV) management for assessing hepatic fibrosis staging. However, some confounders may affect the diagnostic accuracy of the FibroScan device in fibrosis staging. AIM: To evaluate the diagnostic value of the FibroScan device and the effect of hepatic inflammation on the accuracy of FibroScan in assessing the stage of liver fibrosis in patients with HBV infection. METHODS: The data of 416 patients with chronic HBV infection who accepted FibroScan, liver biopsy, clinical, and biological examination were collected from two hospitals retrospectively. Receiver operating characteristic (ROC) curves were used to analyze the diagnostic performance of FibroScan for assessing the stage of liver fibrosis. Any discordance in fibrosis staging by FibroScan and pathological scores was statistically analyzed. Logistic regression and ROC analyses were used to analyze the accuracy of FibroScan in assessing the stage of fibrosis in patients with different degrees of liver inflammation. A non-invasive model was constructed to predict the risk of misdiagnosis of fibrosis stage using FibroScan. RESULTS: In the overall cohort, the optimal diagnostic values of liver stiffness measurement (LSM) using FibroScan for significant fibrosis (≥ F2), severe fibrosis (≥ F3), and cirrhosis (F4) were 7.3 kPa [area under the curve (AUC) = 0.863], 9.7 kPa (AUC = 0.911), and 11.3 kPa (AUC = 0.918), respectively. The rate of misdiagnosis of fibrosis stage using FibroScan was 34.1% (142/416 patients). The group of patients who showed discordance between fibrosis staging using FibroScan and pathological scores had significantly higher alanine aminotransferase and aspartate aminotransferase levels, and a higher proportion of moderate to severe hepatic inflammation, compared with the group of patients who showed concordance in fibrosis staging between the two methods. Liver inflammation activity over 2 (OR = 3.53) was an independent risk factor for misdiagnosis of fibrosis stage using FibroScan. Patients with liver inflammation activity ≥ 2 showed higher LSM values using FibroScan and higher rates of misdiagnosis of fibrosis stage, whereas the diagnostic performance of FibroScan for different fibrosis stages was significantly lower than that in patients with inflammation activity < 2 (all P < 0.05). A non-invasive prediction model was established to assess the risk of misdiagnosis of fibrosis stage using FibroScan, and the AUC was 0.701. CONCLUSION: Liver inflammation was an independent risk factor affecting the diagnostic accuracy of FibroScan for fibrosis stage. A combination of other related non-invasive factors can predict the risk of misdiagnosis of fibrosis staging using FibroScan.

BACKGROUND: The incidence of hepatocellular carcinoma (HCC) is high in China, and approximately 15%-20% of HCC cases occur in the absence of cirrhosis. Compared with patients with cirrhotic HCC, those with non-cirrhotic HCC have longer postoperative tumor-free survival. However, the overall survival time is not significantly increased, and the risk of postoperative recurrence remains. Strategies to improve the postoperative survival rate in these patients are currently required. CASE SUMMARY: A 47-year-old man with a family history of HCC was found to have hepatitis B virus (HBV) infection 25 years ago. In 2000, he was administered lamivudine for 2 years, and entecavir (ETV 0.5 mg) was administered in 2006. In October 2016, magnetic resonance imaging revealed a tumor in the liver (5.3 cm × 5 cm × 5 cm); no intraoperative hepatic and portal vein and bile duct tumor thrombi were found; and postoperative pathological examination confirmed a grade II HCC with no nodular cirrhosis (G1S3). ETV was continued, and no significant changes were observed on imaging. After receiving pegylated interferon alfa-2b (PEG IFNα-2b) (180 µg) + ETV in February 2019, the HBsAg titer decreased significantly within 12 wk. After receiving hepatitis B vaccine (60 µg) in 12 wk, HBsAg serological conversion was realized at 48 wk. During the treatment, no obvious adverse reactions were observed, except for early alanine aminotransferase flares. The reexamination results of liver pathology were G2S1, and reversal of liver fibrosis was achieved. CONCLUSION: The therapeutic regimen of ETV+ PEG IFNα-2b + hepatitis B vaccine for patients with HBV-associated non-cirrhotic HCC following hepatectomy can achieve an HBV clinical cure and prolong the recurrence-free survival.
RESUMO
PURPOSE: Using the Reflux Symptom Index (RSI), this nationwide study aimed to investigate the incidence, diagnostic status, risk factors, and common symptoms of adult laryngopharyngeal reflux disease (LPRD) at otorhinolaryngology-head and neck surgery (OHNS) clinics in China. METHODS: This multicenter cross-sectional survey began at the different institutions ranged from July to October 2017, and the duration was 12 months. A total of 90,440 eligible patients were finally enrolled from 72 medical institutions in China. All these patients completed the questionnaire based on RSI. In this study, LPRD was defined as RSI > 13. RESULTS: There were 9182 with LPRD among the 90,440 eligible participants (10.15%). However, only 1294 had a history of LPRD diagnosis among those with LPRD (14.09%). There were regional differences in the frequency of LPRD (P < 0.001). The proportions of patients with LPRD in males (vs. females), middle- and old-aged patients (vs. young), with current smoking history (vs. no smoking), and current drinking history (vs. no drinking) were significantly higher (all P < 0.001). Middle and old age, current smoking, and drinking history were independent predictors of LPRD (all P < 0.001, OR 1.240, 1.261, and 1.481, respectively). "Sensations of something stuck in throat or a lump in throat", "clearing throat", and "excess throat mucus or postnasal drip" were the most frequent clinical symptoms in patients with LPRD. CONCLUSIONS: LPRD has a high incidence at the OHNS clinics in China. However, the diagnostic status of this disease is not optimistic. Older age, smoking, and drinking history were risk factors for LPRD.

The intestinal microbiome is essential in humans to maintain physiological balance and nutrition metabolism. Laparoscopic cholecystectomy due to gallstone disease and cholecystitis can cause intestinal microbial dysbiosis, and following bile acid metabolism dysfunction, positions the patient at high risk of colorectal cancer. However, little is known regarding intestinal microbiota characteristics in post-cholecystectomy patients. Here, we compared the microbial composition of cholecystectomy patients with that of a healthy population. We determined that cholecystectomy eliminated aging-associated fecal commensal microbiota and further identified several bile acid metabolism-related bacteria as contributors of colorectal cancer incidence via elevation of secondary bile acids. SIGNIFICANCE STATEMENT: We identified aging-associated fecal microbiota in a healthy population, which was lost in cholecystectomy patients. Absent intestinal bacteria, such as Bacteroides, were negatively related to secondary bile acids and may be a leading cause of colorectal cancer incidence in cholecystectomy patients. Our study provides novel insight into the connection between cholecystectomy-altered gut microbiota and colorectal carcinoma, which is of value for colorectal cancer diagnosis and management.
RESUMO
BACKGROUND: CDCA5 plays an important role in the development of various human cancers, but the associated mechanisms have not been investigated in hepatocellular carcinoma (HCC). MATERIALS AND METHODS: We evaluated expression levels and functions of CDCA5 in HCC and showed that CDCA5 is upregulated in HCC tissues compared with paired or unpaired normal liver tissues. RESULTS: Increased CDCA5 expression in HCCs was significantly associated with shorter survival of patients. Knockdown of CDCA5 using lentivirus-mediated shRNA significantly inhibited cell proliferation and suppressed cell survival, as well as induced cell cycle arrest at the G2/M phase and cell apoptosis of HCC cells. The tumor suppression effects of CDCA5 knockdown were mediated by decreased expression of cyclin-dependent kinase 1 (CDK1) and CyclinB1, which were increased in HCC tissues comparing with adjacent normal liver tissues. Moreover, upregulation of CDCA5 was positively associated with increased CDK1 and CyclinB1 expression in HCC tissues. CONCLUSION: The present data warrant consideration of CDCA5 as a prognostic biomarker and therapeutic target for HCC.
RESUMO
CD4 T helper (Th) cells are reported to be essential for initiating and maintaining an effective immune response to hepatitis B virus (HBV) infection. Th9 cells are a new subset of CD4 Th cells that produce interleukin (IL)-9 and IL-10. The present study aimed to investigate the percentage of Th9 cells relative to the number of CD4 cells in peripheral blood. We also measured serum IL-9 and IL-10 levels in different stages of HBV infection and their relationship with progress and prognosis of liver disease. Whole blood samples from 111 patients with HBV infection, including 39 chronic hepatitis B (CHB), 25 HBV-liver cirrhosis (HBV-LC), 21 acute-on-chronic liver failure (ACLF) patients, and 26 healthy controls were collected. The percentage of Th9 cells and serum IL-9 and IL-10 levels were determined. There was no significant difference in the percentage of Th9 cells and serum IL-9 and IL-10 levels among different groups, nor were these related to hepatitis B e antigen status, complications of cirrhosis, inflammation index, or prognosis indexes. There was no change in the percentage of Th9 cells before and after antiviral treatment in CHB patients. There was no correlation of Th9 cells with survival of ACLF patients. However, IL-9 and IL-10 levels were significantly higher in the nonsurvived ACLF patients compared to survived ACLF patients. Furthermore, baseline IL-9 level predicted the prognosis of ACLF patients with 87.5% sensitivity and 61.5% specificity.Thus, our data indicate that Th9 cells were unlikely involved in the pathogenesis of HBV infection, but elevation in IL-9 and IL-10 may signal poor prognosis for ACLF.

OBJECTIVE: To explore the changes in HBsAg titer and HBV DNA load and their correlation in patients with chronic hepatitis B (CHB) and HBV-related liver cirrhosis (HBV-LC). METHODS: Forty-six patients with mild to moderate CHB (CHB-LM), 24 patients with severe CHB (CHB-S), and 28 patients with HBV-LC at admission, and 51 patients with HBV-LC at 4.08 ± 3.06 months during antiviral treatment were tested for serum HBsAg titer and HBV DNA load using Abbott chemiluminescence and fluorescence quantitative PCR, respectively. RESULTS: The serum HBsAg titer and HBV DNA load gradually decreased with increased disease severity (from CHB-LM, CHB-S to HBV-LC; χ(2)=12.537 and 8.381, respectively, P<0.05). HBsAg titer and HBV DNA load were significantly higher in CHB-LM and CHB-S groups than in HBV-LC group (P<0.05), but comparable between CHB-LM and CHB-S groups (Z=-0.649 and 0.032, respectively, P>0.05). Among HBeAg-positive patients, HBsAg titer and HBV DNA load tended to decrease with increased disease severity (from CHB-LM, CHB-S to HBV-LC; χ(2)=6.146, P=0.046 and χ(2)=1.017, P>0.05; respectively), and CHB-LM group had significantly higher HBsAg titer than HBV-LC group (Z=-2.247, P=0.025). Among the HBeAg-negative patients, serum HBsAg and HBV DNA load gradually declined with the disease severity (χ(2)=8.660 and 13.581, respectively, P<0.05), and were obviously higher in CHB-LM and CHB-S groups than in HBV-LC group (P<0.05). Positive correlations were found between serum HBsAg and HBV DNA levels in CHB-LM (r=0.389, P=0.009) and HBV-LC groups (r=0.431, P=0.022), but not in CHB-S group (r=0.348, P=0.104). After antiviral therapy, the serum HBsAg titer was slightly decreased (Z=-1.050, P=0.294) while HBV DNA load markedly reduced (Z=-5.415, P<0.001), showing no correlation between them (r=0.241, P=0.111) or between the measurements before and after treatment (r=0.257, P=0.085). CONCLUSION: Serum HBsAg titer and HBV DNA load decreases progressively from CHB-LM to CHB-S and HBV-LC in both HBeAg- positive and -negative patients. The serum HBsAg titer is positively correlated with HBV DNA load, but their levels are not consistently parallel.

The proinflammatory cytokines transforming growth factor beta 1 (TGF-ß1) and interleukin (IL)-31 have been implicated in tissue injury. However, whether TGF-ß1/IL-31 are stimulated and elevated in response to liver injury that leads to fibrogenesis in hepatitis B virus-related liver cirrhosis (HBV-LC) remains unclear. To investigate the association between TGF-ß1/IL-31 and stages of chronic HBV infection, serum TGF-ß1, IL-9, IL-10,IL-17, IL-22, IL-23, IL-31, IL-33, and IL-35 were determined among patients with chronic hepatitis B (CHB; n=19), HBV-LC (n=20), and a normal control population (NC; n=18). Disease severity in patients with HBV-LC was assessed using model for end-stage liver disease (MELD) scores. Serum TGF-ß1 and IL-31 levels were strongly positively linked in all subjects, and both correlated positively with IL-22, IL-33, and IL-17. TGF-ß1 and IL-31 levels in the blood were both significantly higher in CHB and HBV-LC patients than in NC subjects. Elevated serum TGF-ß1 and IL-31 levels were positively associated with albumin, alpha-fetoprotein, creatinine, white blood cell count, and platelet levels. Serum TGF-ß1 and IL-31 were markedly higher in HBV-LC patients who did not have esophageal varices, and IL-31 had the highest sensitivity and specificity (90.9% and 66.7%, respectively) for indicating the absence of this complication. In summary, TGF-ß1 and IL-31 were linked to progression from CHB to LC, and correlated well with the severity of HBV-LC. These findings suggest possible roles of the TGF-ß1/IL-31 pathway in the pathogenesis of liver fibrosis during chronic HBV infection.

The transforming growth factor ß1/interleukin-31 (TGF-ß1/IL-31) pathway plays an important role in the process of cell injury and inflammation. The purpose of this work was to explore the role of the TGF-ß1/IL-31 pathway in the cytopathic process of hepatitis B virus (HBV)-related acute-on-chronic liver failure (ACLF). The quantitative serum levels of TGF-ß1, IL-9, IL-10, IL-17, IL-22, IL-23, IL-31, IL-33, and IL-35 were analyzed among chronic hepatitis B (CHB) patients (n = 17), ACLF patients (n = 18), and normal control (NC) subjects (n = 18). Disease severity in patients with ACLF was assessed using the model for end-stage liver disease (MELD) and Child-Pugh scores. Serum TGF-ß1 levels were strongly positively correlated with IL-31 in all subjects, and both of them were positively correlated with IL-17, IL-22, and IL-33. In CHB and ACLF patients, serum levels of TGF-ß1 and IL-31 were both increased significantly compared with those in NC subjects and positively correlated with total bilirubin (TBil) and alpha-fetoprotein (AFP) levels. ACLF patients showed the highest levels of TGF-ß1 and IL-31, which were positively correlated with Child-Pugh scores. Furthermore, the recovery from the liver injury in CHB was accompanied by decreased TGF-ß1 and IL-31 levels. More importantly, serum levels of TGF-ß1 and IL-31 were markedly upregulated in ACLF nonsurvivors, and IL-31 displayed the highest sensitivity and specificity (85.7% and 100.0%, respectively) in predicting nonsurvival of ACLF patients. Increasing activity of the TGF-ß1/IL-31 pathway is well correlated with the extent of liver injury, disease severity, and nonsurvival of ACLF patients, while reducing activity is detected along the recovery from liver injury in CHB, suggesting its potential role in the pathogenesis of liver injury during chronic HBV infection.

AIMS: The aim of this paper is to examine the familial aggregation of cannabis use disorders and other psychiatric conditions among first-degree relatives and spouses of probands with a cannabis use disorder. DESIGN: Controlled family study methods. SETTING: Out-patient psychiatric clinics and the local community (same geographic area). PARTICIPANTS: Two hundred and sixty-two probands with a life-time history of cannabis use disorder, alcohol dependence, anxiety disorders or no history of any disorder, and their first-degree relatives and spouses. MEASUREMENTS: Cannabis use disorders and other DSM-III-R disorders in the relatives and spouses using the Schedule for Affective Disorders and Schizophrenia. FINDINGS: Results reveal an elevated risk of life-time history of cannabis use disorders among siblings [odds ratio (OR: 3.6), adult offspring (OR): 6.9], and spouses (OR: 4.4) of probands with cannabis use disorders. There is a latent familial factor underlying cannabis use disorders that was shared partially with alcohol abuse/dependence. Comorbid mood and anxiety disorders aggregated independently from cannabis use disorders in families. Equal elevation in the magnitude of the association among the first-degree adult relatives and spouses of probands with a cannabis use disorder suggests the probable contribution of both environmental and genetic factors. CONCLUSIONS: These findings support a family-based approach to drug abuse intervention and the importance of future research concerning environmental mediators of familial transmission of drug abuse.
