    Insights

    The current classification of chronic hepatitis needs refinement. New criteria, including bridging hepatic necrosis and lobular activity, can improve diagnosis and prognosis for chronic hepatitis, chronic persistent hepatitis, and chronic active hepatitis.

    Area of Science:

    • Hepatology
    • Gastroenterology
    • Pathology

    Background:

    • The current diagnostic subdivision of chronic hepatitis into chronic persistent hepatitis (CPH) and chronic active hepatitis (CAH) requires updates.
    • Distinguishing between mild CAH and CPH can be challenging, with potential for misclassification due to treatments like corticosteroids or sampling errors.

    Purpose of the Study:

    • To propose a refined classification system for chronic hepatitis that addresses limitations in current diagnostic categories.
    • To incorporate key pathological features like bridging hepatic necrosis (BHN) and lobular activity into a more practical diagnostic framework.

    Main Methods:

    • Review and analysis of existing diagnostic criteria for chronic hepatitis.
    • Evaluation of pathological features, including portal/periportal inflammation, necrosis, bridging hepatic necrosis (BHN), and lobular activity, as predictors of chronicity and prognosis.

    Main Results:

    • Mild CAH can mimic CPH, and treatments may alter presentation.
    • Sampling errors can lead to apparent transitions between CPH and CAH.
    • Bridging hepatic necrosis (BHN) is a critical feature in CAH associated with rapid cirrhosis development.
    • Lobular activity, when present alone, suggests a distinct entity: chronic lobular hepatitis.

    Conclusions:

    • The existing classification of chronic hepatitis into CPH and CAH needs modification.
    • Incorporating BHN and recognizing chronic lobular hepatitis can lead to a more accurate and practical re-classification of chronic hepatitis, improving prognostic assessment.

    Liver Histology

    The microscopic anatomy of the liver is a complex and intricate system that comprises numerous structural units known as liver lobules, each of which is comparable in size to a sesame seed. These hexagonal structures consist of plates of liver cells or hepatocytes, which are characterized by their versatility and abundance of cellular apparatus like rough and smooth ER, Golgi apparatus, peroxisomes, and mitochondria.
    Hepatocytes perform a variety of essential functions. They secrete...

    Chronic Pancreatitis I: Introduction

    The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
    Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
    Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
    Chronic Inflammation: Introduction01:12

    Chronic Inflammation: Introduction

    Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...

    Cirrhosis I: Introduction

    Cirrhosis is a chronic, irreversible liver disease characterized by the widespread replacement of healthy liver tissue with fibrotic scar tissue and the formation of regenerative nodules.Etiology of cirrhosisCirrhosis results from sustained liver injury that triggers progressive fibrosis and structural remodeling. The underlying causes are diverse, encompassing common and less frequent clinical conditions. Regardless of the origin, all causes lead to chronic inflammation, hepatocyte loss, and...

    Cirrhosis II: Pathophysiology

    Cirrhosis is a progressive chronic liver injury caused by prolonged inflammation, excessive fibrotic remodeling, and impaired regeneration. Over time, repeated hepatic insults disrupt the liver’s architecture and function, leading to reduced blood flow, impaired bile drainage, and diminished metabolic capacity.Pathophysiology of cirrhosisCirrhosis arises from three main responses to chronic liver damage: inflammation, immune activation, and hepatocyte death. These processes lead to structural...
    Chronic Pancreatitis I: Introduction01:25

    Chronic Pancreatitis I: Introduction

    Chronic pancreatitis is a long-standing, relapsing inflammation of the pancreas, characterized by irreversible damage to the gland. It results in progressive destruction of the pancreatic parenchyma, fibrosis, and eventual loss of both exocrine and endocrine function. The disease may evolve gradually after multiple episodes of acute pancreatitis or develop independently.EtiologyChronic pancreatitis can arise from a variety of causes:Alcohol use is the leading cause, accounting for 70–80% of...
