Asthma: Pathogenesis and Management

1.7K
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.

Asthma-II: Pathophysiology and Classification

5.0K
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

6.3K
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...

Asthma I: Introduction

3
Asthma is a chronic inflammatory disorder of the airways characterized by variable airflow obstruction and heightened bronchial responsiveness to a wide range of triggers. The underlying inflammation leads to airway swelling, mucus hypersecretion, and smooth muscle constriction, all of which narrow the airway lumen and impede airflow. Clinically, asthma presents with recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing, symptoms that typically vary in intensity and...

Acne Infection

75
Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...

Area of Science:

  • Immunology
  • Dermatology
  • Genetics

Background:

  • Atopic dermatitis (AD) is a prevalent allergic inflammatory skin condition.
  • Its pathogenesis involves intricate interactions between genetic, environmental, and immunological factors.
  • AD presents with characteristic eczematous, pruritic lesions, but trigger factors and pathophysiologic networks are complex.

Purpose of the Study:

  • To review key concepts in the pathogenesis of atopic dermatitis.
  • To summarize recent findings and discuss cofactors impacting AD.
  • To elucidate immunological factors, microbiome role, and T helper cell involvement in AD.

Main Methods:

  • Literature review summarizing recent findings on AD pathogenesis.
  • Discussion of immunological factors, microbiome, and T helper cell subtypes.
  • Analysis of cofactors influencing AD manifestation and disease course.

Main Results:

  • AD pathogenesis is multifactorial, involving genetic, environmental, and immune system components.
  • Skin barrier dysfunction is a key feature, influenced by immunological factors and the microbiome.
  • Specific T helper cell patterns and innate lymphoid cells play roles in AD at different stages.

Conclusions:

  • Stratifying AD patients into subtypes based on causal factors requires detailed knowledge of cofactors.
  • Understanding the complex interplay of immune responses, microbiome, and genetics is essential for targeted therapies.
  • Further research into AD pathogenesis can optimize patient management and treatment strategies.
