Hypersensitivities

837
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...

Allergic Drug Reactions

904
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...

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs

365
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...

Asthma-II: Pathophysiology and Classification

2.7K
Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:

Skin Diseases and Disorders

4.0K
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Summary
This summary is machine-generated.

Urticaria and angioedema stem from histamine release, diagnosed clinically. Treatment involves trigger avoidance and H1 antihistamines, with doses potentially increased.

Area of Science:

  • Immunology
  • Dermatology
  • Allergy

Background:

  • Urticaria and angioedema result from mast cell and basophil release of inflammatory mediators.
  • Both immunoglobulin E (IgE)-dependent and non-IgE-dependent pathways contribute to mediator release.

Purpose of the Study:

  • To outline the diagnostic and management principles for urticaria and angioedema.
  • To emphasize clinical diagnosis and the exclusion of anaphylaxis.

Main Methods:

  • Clinical diagnosis based on patient history and physical examination.
  • Consideration of limited laboratory workup for specific underlying conditions.
  • Pharmacotherapy with second-generation H1 antihistamines as first-line treatment.

Main Results:

  • Diagnosis is primarily clinical, requiring differentiation from anaphylaxis.
  • Trigger identification and avoidance are key management strategies.
  • H1 antihistamines are effective, with potential for dose titration.

Conclusions:

  • Urticaria and angioedema management relies on clinical assessment and trigger avoidance.
  • Pharmacological treatment prioritizes H1 antihistamines, allowing for dose escalation.
  • A targeted, limited laboratory approach is recommended when indicated.
