    Insights

    Chronic hepatitis is complex, with proposed subtypes like chronic persisting hepatitis (CPH) and chronic active hepatitis (CAH). Definitive diagnosis requires integrating clinical, biochemical, serologic, and immunologic data due to overlapping features.

    Area of Science:

    • Hepatology
    • Pathology
    • Immunology

    Context:

    • Chronic hepatitis lacks a universally accepted definition and nomenclature.
    • Recent proposals subdivide chronic hepatitis into chronic persisting (CPH) and chronic active (CAH) forms.
    • Distinguishing between CPH and CAH is challenging due to overlapping clinical and pathological features.

    Purpose:

    • To clarify the distinctions and diagnostic criteria for chronic hepatitis subtypes.
    • To highlight the morphological differences between CPH and CAH.
    • To emphasize the necessity of comprehensive diagnostic data.

    Summary:

    • Chronic persisting hepatitis (CPH) is characterized by mononuclear inflammatory infiltration in portal fields with preserved lobules.
    • Chronic active hepatitis (CAH) features periportal inflammation (piecemeal necrosis), potentially with hepatocytolysis and confluent necroses in severe cases.
    • Hepatitis B-positive CPH shows specific immunofluorescence findings like orcein-positive hepatocytes and altered nuclei.

    Impact:

    • Improved understanding of chronic hepatitis classification.
    • Guidance for clinicians in diagnosing and differentiating hepatitis subtypes.
    • Foundation for further research into hepatitis pathogenesis and treatment.

    Liver Regeneration

    The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.
    Cells of Liver
    The liver comprises four major types of cells— hepatocytes, stellate, Kupffer, and sinusoidal endothelial cells. The hepatocytes are large...

    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...

    Hepatitis

    Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...

    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: Pathophysiology01:24

    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...
