Asthma: Pathogenesis and Management

1.1K
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

1.3K
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...

Drugs Used in Upper Respiratory Disorders: Overview

541
Upper respiratory tract disorders, including viral infections and allergic rhinitis, cause significant discomfort and disrupt daily life. Managing these conditions involves a variety of drugs, such as antihistamines, intranasal steroids, decongestants, antitussives, expectorants, and mucolytics. Specific examples of drugs in each category are provided.
Antihistamines (e.g., Benadryl) block histamines from binding. Histamines are chemicals released during an allergic reaction in the body. As a...

Asthma-II: Pathophysiology and Classification

3.9K
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-I: Introduction

3.3K
Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...

Summary

Local allergic rhinitis (LAR) is often misdiagnosed, leading to improper treatment. Recognizing LAR is crucial for effective management and potential allergen immunotherapy (AIT).

Area of Science:

  • Allergy and Immunology
  • Otolaryngology
  • Respiratory Medicine

Background:

  • Local allergic rhinitis (LAR) presents a diagnostic and therapeutic challenge.
  • It affects numerous chronic rhinitis patients but remains underrecognized, leading to misdiagnosis and mistreatment.
  • LAR is distinct from classical allergic rhinitis (AR) and non-allergic rhinitis (NAR).

Purpose of the Study:

  • To summarize current knowledge on Local Allergic Rhinitis (LAR).
  • To address unmet needs in LAR diagnosis and treatment.
  • To highlight the implications of underdiagnosis and mistreatment of LAR.

Main Methods:

  • Comprehensive literature review on Local Allergic Rhinitis (LAR).
  • Analysis of diagnostic challenges and therapeutic strategies.
  • Evaluation of the distinction between LAR, AR, and NAR.

Main Results:

  • LAR symptoms mimic AR, affecting both adults and children.
  • Patients diagnosed with NAR or idiopathic rhinitis may have undiagnosed LAR.
  • Misdiagnosis deprives patients of potentially effective allergen immunotherapy (AIT).

Conclusions:

  • Local Allergic Rhinitis (LAR) requires specific diagnostic tests for accurate identification.
  • Improved diagnostic approaches are needed to differentiate LAR from other rhinitis types.
  • Timely diagnosis of LAR is essential for appropriate patient management and treatment, including AIT.
