Gastritis III: Clinical Manifestations and Management

Gastritis III: Clinical Manifestations and Management

The clinical manifestations of gastritis can vary depending on the cause and type of gastritis, but some common symptoms may include the following.
Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...

Viral Hepatitis I: Introduction

Viral Hepatitis I: Introduction

Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...

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...

Acute Pancreatitis II: Clinical Manifestations and Management

Acute Pancreatitis II: Clinical Manifestations and Management

Acute pancreatitis presents a complex medical emergency characterized by rapid onset inflammation of the pancreas, demanding timely diagnosis and management to prevent complications. The condition primarily manifests through severe upper abdominal pain that often radiates to the back. This pain intensifies following the consumption of fatty foods. Accompanying symptoms such as nausea, vomiting, abdominal distention, fever, dyspnea, cyanosis, and jaundice can vary in intensity but significantly...

Autoimmune Disorders

Autoimmune Disorders

Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

Gastritis-II: Pathophysiology

Gastritis-II: Pathophysiology

Gastritis is marked by disruption of the mucosal barrier that usually protects the stomach tissue from digestive juices and manifests in acute and chronic forms.
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

Summary

Autoimmune hepatitis, a rare liver disease, presents with elevated liver enzymes and responds well to prednisolone treatment. Early diagnosis and immunosuppressive therapy are crucial for improving patient prognosis and preventing advanced disease requiring liver transplantation.

Background:

Autoimmune hepatitis (AIH) is a rare, chronic liver disease characterized by autoimmune-mediated liver inflammation.
Diagnosis can be challenging due to varied presentations and exclusion of other liver diseases.

Observation:

Two female patients presented with jaundice, elevated liver enzymes, and hypergammaglobulinaemia.
Both patients tested negative for viral hepatitis and showed high titers of antinuclear antibodies (ANA) and smooth muscle antibodies (SMA).
Liver biopsies confirmed autoimmune hepatitis in both cases.

Findings:

Both patients responded well to high-dose prednisolone therapy, with significant improvement in clinical and laboratory parameters.
Case 1 showed rapid recovery, while Case 2 experienced a slower recovery with complications requiring further management.
Advanced disease in Case 2 may necessitate a future liver transplantation.

Implications:

Prompt investigation of elevated liver enzymes is essential for early AIH diagnosis.
Immunosuppressive therapy, particularly with prednisolone, is effective in managing AIH.
Timely diagnosis and treatment significantly improve patient outcomes and prognosis, potentially avoiding the need for liver transplantation.
