Hypersensitivities

1.1K
Hypersensitivity, also known as a hypersensitivity reaction or allergic reaction, is a condition where the body's immune system reacts abnormally to a foreign substance. Such substances, that cause hypersensitivity are referred to as an allergen, could be something typically harmless to most people, like pollen or certain foods.
Types of Hypersensitivities
Hypersensitivity reactions are categorized into four types: Type 1, Type 2, Type 3, and Type 4. Each type has a distinct mechanism...

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs

613
Asthma is a chronic respiratory condition for which new therapeutic avenues, including anti-inflammatory drugs like mast cell stabilizers and anti-IgE treatments, continue to be developed.
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...

Gastritis III: Clinical Manifestations and Management

547
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...

Gastritis-I: Introduction and Types

1.1K
Gastritis, defined by the inflammation or irritation of the stomach lining or gastric mucosa, manifests in several distinct forms: acute, chronic, reactive, and a specific subtype known as autoimmune metaplastic atrophic gastritis.
Acute gastritis presents as a sudden inflammation triggered by various stressors to the stomach lining, such as exposure to corrosive agents, local irritants like aspirin and other NSAIDs, alcohol consumption, radiation therapy, physical trauma, severe burns, sepsis,...

Allergic Drug Reactions01:27

Allergic Drug Reactions

1.0K
Allergic reactions related to drugs are hypersensitivity responses driven by the immune system and bear no connection to the drug's therapeutic action. While drugs in isolation do not trigger an immune response, they can interact with endogenous proteins to form antigens. These antigens stimulate lymphocytes to produce antibodies. IgE-type antibodies attach themselves to mast cells. Upon subsequent exposure to the same stimulus, the antigen-antibody interaction is initiated, unleashing...

Area of Science:

  • Immunology
  • Genetics
  • Rare Diseases

Background:

  • Hyper IgE syndromes (HIESs) are rare inborn errors of immunity.
  • Characterized by eczema, recurrent sinopulmonary and skin infections, and elevated serum IgE.
  • Diagnosis is challenging due to phenotypic overlap with other immunodeficiencies.

Purpose of the Study:

  • To provide an overview of Hyper IgE syndromes.
  • To highlight key clinical and laboratory features.
  • To propose a practical diagnostic approach for HIESs.

Main Methods:

  • Review of existing literature on HIESs.
  • Analysis of clinical and immunological characteristics.
  • Development of a diagnostic algorithm.

Main Results:

  • HIESs present with a distinct triad of symptoms.
  • Genetic mutations, such as DOCK8, are critical for diagnosis and treatment.
  • Hematopoietic stem cell transplantation is a necessary treatment for autosomal recessive HIESs.

Conclusions:

  • Early diagnosis and preventive therapies are essential for HIES management.
  • Genetic diagnosis plays a vital role in guiding treatment decisions.
  • A structured diagnostic approach can improve patient outcomes for HIESs.
