Asthma-II: Pathophysiology and Classification

2.6K
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:

Asthma: Pathogenesis and Management

346
Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

Allergic Drug Reactions

807
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...

Hypersensitivities01:30

Hypersensitivities

497
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...

Sensory Functions of the Skin01:16

Sensory Functions of the Skin

4.5K
The skin is the largest organ of the human body and plays a crucial role in our sensory perception. It contains a vast network of sensory receptors that contribute to the skin's protective function by perceiving physical, biological, and environmental cues and generating relevant responses.
There are two main categories of receptors on the skin: capsulated and non-capsulated. The non-capsulated ones are mainly the pain receptors. The capsulated ones can be further categorized based on the...

Area of Science:

  • Dermatology
  • Immunology
  • Genetics

Background:

  • Atopic dermatitis (AD) is a prevalent skin condition associated with allergic rhinitis and asthma, characterized by intense itching and relapses.
  • Its global incidence has risen significantly, making it the third most common dermatologic disorder.
  • AD impacts quality of life and is a growing public health concern.

Purpose of the Study:

  • To review recent scientific advancements in understanding the pathophysiologic mechanisms of atopic dermatitis (AD).
  • To highlight the clinical applications of newly discovered factors in AD pathogenesis.
  • To address existing questions regarding the underlying mechanisms of AD.

Main Methods:

  • A comprehensive PubMed search was conducted using keywords related to AD epidemiology, clinical presentation, diagnosis, and pathophysiology.
  • The search included various study types such as meta-analyses, clinical trials, observational studies, and reviews.
  • Specific search terms focused on genetic defects, impaired skin barrier, and immune dysregulation in AD.

Main Results:

  • Atopic dermatitis affects over 2 million children globally, with a lifetime incidence up to 20%, and its incidence continues to rise, especially in low-income countries.
  • Clinical diagnosis relies on medical history, characteristic symptoms, and exclusion of other skin conditions.
  • AD pathogenesis is multifactorial, involving genetics, the microbiome, skin barrier defects, and immune system dysfunction.

Conclusions:

  • Recent research has significantly enhanced the understanding of atopic dermatitis pathophysiology.
  • Ongoing and future clinical trials will further elucidate this complex disease.
  • New therapeutic strategies are anticipated, offering improved treatment options for individuals with limited response to conventional therapies.
