Description

Chronic Hepatitis B Virus (HBV) infection is a leading cause of chronic liver diseases, resulting in liver fibrosis and cirrhosis. Patients infected with HBV eventually die of end-stage liver disease or develop hepatocellular carcinoma. Early liver damage prevention and anti-fibrotic medication can effectively postpone the course of liver problems. As a result, assessing hepatic fibrosis is an important step in the management of chronic liver disorders. A liver biopsy is the gold standard for fibrosis diagnosis. However, it is intrusive, has sampling error, inconsistency among various observers, and other flaws. These limitations severely restrict the use of liver biopsy in the identification of illnesses such as chronic hepatitis B. As a result, identifying convenient and noninvasive markers for the clinical detection of liver disorders is critical. Diagnostic models based on combined serum indicators have gained popularity in liver fibrosis research during the last decade. As novel diagnostic tests, models for Chronic Hepatitis C (CHC), such as Fibrotest, Forns index, Aspartate aminotransferase (AST) to Platelet Ratio Index (APRI), and Hepascore, and models for Chronic Hepatitis B (CHB), such as SLFG model, The findings of our earlier work showed that these models have some diagnostic relevance for liver fibrosis, however the sensitivity and specificity of serum markers alone do not entirely match the clinical criteria. The presence and activity of Hepatitis B Virus (HBV) tests are the foundations of diagnosis and therapy. To identify patients with HBV exposure, assays that detect or measure serum levels of HB surface antigen, HB surface antibody, and HB core antibody are used, whereas other tests provide information on the level of virus replication, the presence of specific variants, and the presence of virus reservoirs. Newer diagnostic assays, which have so far only been used in research settings, try to measure levels of intrahepatic HBV replication. In resource-constrained areas, several tests have been developed to diagnose HBV infection. We examine point-of-care testing (crucial in global screening initiatives), traditional diagnostic tests used in normal clinical management, and novel tests that may be employed in Agents targeted to treat HBV infection are being tested in clinical studies. Chronic hepatitis is defined as persistent or relapsing hepatitic liver injury lasting more than 6 months and includes the most common liver diseases: Viral hepatitis, autoimmune hepatitis, drug-induced liver injury, and fatty liver disease, as well as less common inherited metabolic disorders such as Wilson disease and alpha-1-antitrypsin deficiency. Chronic cholestatic liver disease can proceed to severe fibrosis and is frequently misdiagnosed as chronic hepatitis. Histologic characteristics may overlap, particularly at an advanced stage, therefore morphologic findings, in conjunction with the whole clinical context, are crucial in making a correct diagnosis. Pathologic and clinical aspects of a hepatitic liver disease spectrum that can cause chronic hepatitis, as well as diagnostic testing needed to establish a diagnosis or discriminate between these entities chronic hepatitis is defined as ongoing or relapsing hepatic illness for at least 6 months, regardless of origin. It is distinguished by various degrees of hepatic inflammation (mostly lymphocytic), necrosis, and fibrosis. These individuals often have increased serum Aspartate (AST) and alanine transaminase (ALT) values. Historically, viral hepatitis, including Hepatitis C Virus (HCV) and Hepatitis B Virus (HBV) with or without Hepatitis D Virus, was the most prevalent cause of chronic hepatitis (HDV). In the United States, fatty liver disease has emerged as the most frequent cause of chronic liver disease, although other prominent etiologies include Autoimmune Hepatitis (AIH) and Drug-Induced Liver Damage (DILI). As less prevalent hereditary metabolic diseases, Wilson disease and Alpha-1-Antitrypsin (A1AT) deficiency enter the differential diagnosis. In certain cases, especially in advanced stages, there will be no specific histologic characteristics to identify aetiology; hence linkage with clinical and imaging evidence is required to arrive at an accurate diagnosis. Chronic cholestatic liver disease (PBC and PSC) can proceed to severe liver disease and should be separated from other causes. Pathologic and clinical aspects of a spectrum of hepatitic liver disease that can cause chronic hepatitis, as well as diagnostic tests that can help the pathologists in developing a diagnosis.
