Summary
Nasal allergy, linked to asthma, impairs lung function. Specifically, forced expiratory flow (FEF25-75%) may indicate early bronchial issues and predict airway hyperresponsiveness in allergy patients.
Area of Science:
- Respiratory Medicine
- Allergology
- Pulmonology
Background:
- Nasal allergy involves IgE-mediated inflammation of the nasal mucosa.
- Nasal allergy is a significant risk factor for adult-onset asthma.
- Allergic rhinitis is recognized as a precursor to asthma development.
Purpose of the Study:
- To assess spirometric parameter impairment in nasal allergy patients.
- To evaluate the relationship between nasal allergy and early bronchial obstruction.
- To predict airway hyperresponsiveness in individuals with allergic rhinitis.
Main Methods:
- Spirometry was used to measure Forced Expiratory Volume in 1 second (FEV1) and Forced Expiratory Flow between 25-75% of FVC (FEF25-75%).
- Patients with nasal allergy were evaluated for spirometric abnormalities.
- The study aimed to correlate spirometric findings with the risk of asthma development.
Main Results:
- Spirometric parameters, including FEV1 and FEF25-75%, are often impaired in patients with nasal allergy.
- FEF25-75% is a sensitive marker for early bronchial impairment in nasal allergy.
- FEF25-75% may predict airway hyperresponsiveness and is linked to persistent respiratory symptoms in asthmatics.
Conclusions:
- Nasal allergy can be considered an initial stage in the progression towards asthma.
- Spirometric abnormalities are common in allergic rhinitis patients.
- FEF25-75% is a valuable indicator for predicting airway hyperresponsiveness and potential asthma development.

01:19Factors Affecting Pulmonary Ventilation
3.6K
Besides the pressure difference between the external environment and the lungs, the airflow rate and ease of pulmonary ventilation are also influenced by three other factors: surface tension of the fluid in the alveoli, compliance of the lungs, and airway resistance.
Alveolar Surface Tension
The alveolar fluid lines the luminal surface of the alveoli and exerts a force called surface tension. This force is caused by the polar water molecules in the liquid being more strongly attracted to each...

01:20Asthma: 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.

01:16Drugs Used in Upper Respiratory Disorders: Overview
983
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 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...
