Liver fibrosis in chronic hepatitis B is the pathological repair response of the liver to chronic injury, which is a key step in the development of various chronic liver diseases to cirrhosis and an important link affecting the prognosis of chronic liver diseases. The further development of liver fibrosis in chronic hepatitis B can lead to the disorder of hepatic lobule structure, nodular regeneration of hepatocytes, formation of a pseudolobular structure, namely, cirrhosis, clinical manifestations of liver dysfunction, and portal hypertension. So far, the diagnosis of liver fibrosis in chronic hepatitis B has been made manually by doctors. However, this is very subjective and boring for doctors. Doctors are likely to be interfered with by external factors, such as fatigue and lack of sleep. This paper proposed a 5-layer deep convolution neural network structure for the automatic classification of liver fibrosis in chronic hepatitis B. In the 5-layer deep convolution neural network structure, there were three convolution layers and two fully connected layers, and each convolution layer was connected with a pooling layer. 123 ADC images were collected, and the following results were obtained: the accuracy, sensitivity, specificity, precision, F1, MCC, and FMI were 88.13% ± 1.47%, 81.45% ± 3.69%, 91.12% ± 1.72%, 80.49% ± 2.94%, 80.90% ± 2.39%, 72.36% ± 3.39%, and 80.94% ± 2.37%, respectively.

Introduction. Pronounced symptoms of depression and disorders of cognitive functions can be observed in patients with chronic hepatitis B. Objective. The objective of the study was evaluation of the severity of symptoms and predictive factors for depression and the existence of cognitive disorders in patients with chronic hepatitis B. Methods. A total of 150 respondents were included in this prospective study (50 patients with chronic hepatitis B, 50 patients with other chronic liver diseases and 50 healthy persons). The patients with chronic hepatitis B were homogeneous by age compared to healthy subjects (p=0.566) and patients with other chronic liver diseases (p=0.528). Assessment of intensity of depression was determined by the Hamilton Depression Rating Scale (HAMD). A Mini Mental State Examination (MMSE) test was used to investigate the presence of cognitive disorders. Results. Significantly expressed depression was observed in patients with chronic hepatitis B compared with healthy persons as well as the occurrence of cognitive dysfunction (p=0.00), while in comparison with the patients with chronic nonviral liver diseases, depression was statistically significantly less markedly expressed (p=0.003). Depression and cognitive dysfunction were more noticeable in patients with chronic hepatitis B in the stage of liver cirrhosis in relation to the early stage of the disease. Multivariate analysis of variables related to the sociodemographic characteristics showed that the most significant positive predictor of depression was more expressed in older age (over 50 years) (B=0.276; SE=0.092; p=0.004). Conclusion. Patients with chronic hepatitis B have a higher intensity of depression compared to healthy people, which is intensified with the progression of the disease. The highest expression of depression is expected in the elderly. Patients with chronic hepatitis B have a lower intensity of depression and fewer disorders of cognitive functions than patients with other chronic liver diseases.

Abstract Background: Hepatocellular carcinoma (HCC) is the most serious tumor in the world. It generally undergoes a series of processes from HBV infection, chronic hepatitis, cirrhosis, and HCC from early to late stages. Patients could benefit from early detection of chronic liver diseases (CLD). Tumor-Educated Platelets play an important role in tumor progression, which maybe a potential biomarker for CLD early diagnosis. Here, we developed a noninvasive liquid biopsy technique using platelet RNA for the early screening of patients with liver diseases. Methods: This study included a total of 163 individuals, including 50 healthy individuals, 39 chronic hepatitis B (CHB) patients, 40 liver cirrhosis (LC) and 34 patients with HCC. Blood was collected before initiation of treatment. Platelet RNA-Seq combined with Support Vector Machine (SVM), was used for the first time to distinguish the different stages of CLD in Asian patients.Results: Developed diagnostic model could distinguished with 92.4% accuracy between 34 HCC and 50 healthy, 89.92% accuracy between 34 patients HCC and 129 non-cancer individuals, and 83.67% between 50 healthy and 113 CLD. Across four different individual types, the accuracy of distinction (healthy/chronic hepatitis B/liver cirrhosis/hepatocellular carcinoma) was 65.31%. This model was internally validated, resulting in optimism-corrected AUC's of 86.8%.Conclusions: Our data indicate that the developed platelet RNA-Seq is a valuable platform for the diagnosis of CLD, providing an effective solution for its diagnosis.

Both consensus and controversy remains regarding surrogacy of hepatitis B virus (HBV) deoxyribonucleic acid (DNA) and alanine aminotransferase (ALT), however, these markers are used to ascertain the extent of liver damages and to guide therapeutic options in patients with chronic hepatitis B. However, little is known about liver histology of patients with chronic hepatitis B with undetectable HBV DNA and persistently normal ALT. Thirty-five incidentally-detected patients with chronic HBV infection (assessed by expression of hepatitis B surface antigen for more than 6 months) with undetectable HBV DNA and normal serum ALT were enrolled in this study. Liver biopsy specimens were taken from all patients and the extent of hepatic necroinflammation and liver fibrosis were evaluated. Moderate degree of hepatic necroinflammation was detected in 2 of 35 patients and severe hepatic fibrosis was seen in 6 of 35 patients. Two patients with undetectable HBV DNA and sustained normal ALT had moderate hepatic necroinflammation and severe hepatic fibrosis. In spite of undetectable HBV DNA for prolonged period and persistently normal ALT, some patients with chronic hepatitis B express evidences of progressive liver diseases. Large scale studies in different races and geographical regions should be accomplished to develop insights about management of these patients. Studies about extent of liver diseases in these patients should be accomplished in Treatment recommendation and management strategies should be developed for these patients.Bangladesh Med Res Counc Bull 2014; 40 (3): 92-96

Routine Assessment

OBJECTIVE: To determine practices among physicians in Canada for the assessment of liver fibrosis in patients with chronic liver diseases.METHODS: Hepatologists, gastroenterologists, infectious diseases specialists, members of the Canadian Gastroenterology Association and/or the Canadian HIV Trials Network who manage patients with liver diseases were invited to participate in a web-based, national survey.RESULTS: Of the 237 physicians invited, 104 (43.9%) completed the survey. Routine assessment of liver fibrosis was requested by the surveyed physicians mostly for chronic hepatitis C (76.5%), followed by autoimmune/cholestatic liver disease (59.6%) and chronic hepatitis B (52.9%). Liver biopsy was the main diagnostic tool for 46.2% of the respondents, Fibroscan (Echosens, France) for 39.4% and Fibrotest (LabCorp, USA) for 7.7%. Etiology-specific differences were observed: noninvasive methods were mostly used for hepatitis C (63% versus 37% liver biopsy) and hepatitis B (62.9% versus 37.1% liver biopsy). For 42.7% of respondents, the use of noninvasive methods reduced the need for liver biopsy by >50%. Physicians’ characteristics associated with higher use of noninvasive methods were older age and being based at a university hospital or in private practice versus community hospital. Physicians’ main concerns regarding noninvasive fibrosis assessment methods were access/availability (42.3%), lack of guidelines for clinical use (26.9%) and cost/lack of reimbursement (14.4%).CONCLUSIONS: Physicians who manage patients with chronic liver diseases in Canada require routine assessment of liver fibrosis stage. Although biopsy remains the primary diagnostic tool for almost one-half of respondents, noninvasive methods, particularly Fibroscan, have significantly reduced the need for liver biopsy in Canada. Limitations in access to and availability of the noninvasive methods represent a significant barrier. Finally, there is a need for clinical guidelines and a better reimbursement policy to implement noninvasive tools to assess liver fibrosis.
