Summary
Many dust-mite (DM) allergic patients undergoing immunotherapy do not follow environmental avoidance guidelines. Cost is a significant barrier to using protective covers and replacing carpets, impacting allergen exposure reduction.
Area of Science:
- Allergy and Immunology
- Environmental Health
Background:
- Compliance with environmental avoidance measures for dust-mite (DM) allergic patients receiving immunotherapy (IT) is not well-documented.
- Indoor allergens, including dust mites, pets, mold, and cockroaches, are common triggers for allergic reactions.
Purpose of the Study:
- To investigate the practices of patients receiving immunotherapy for indoor allergens, focusing on dust-mite allergy.
- To identify barriers to compliance with environmental avoidance strategies.
Main Methods:
- A questionnaire was distributed to 200 patients receiving IT for indoor allergies.
- Ninety-three patients completed the survey, with a focus on those allergic to dust mites (69% of respondents).
Main Results:
- Only 53% of dust-mite allergic patients used mattress covers and 61% used pillow covers.
- High percentages reported reducing home moisture (81%) and washing linens in hot water (83%).
- Cost was the primary reason cited for not using covers (52%) or replacing carpets (49%).
Conclusions:
- A significant proportion of patients with dust-mite allergy undergoing immunotherapy do not consistently implement environmental avoidance measures.
- Cost is a major factor limiting patient adherence to recommended avoidance strategies.
- Mandating extensive avoidance measures before initiating immunotherapy may not be practical for many patients.

01:25Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
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...

01:25Transmission-based Precautions II: Airborne and Protective Environment
Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

01:20Asthma: Pathogenesis and Management
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.

01:25Antiasthma Drugs: Inhaled Corticosteroids and Glucocorticoids
Inhaled corticosteroids (ICS) are anti-inflammatory drugs used primarily in treating persistent asthma and providing long-term maintenance. They target the bronchial mucosa, the lining of the airways, to control inflammation, a critical factor in asthma progression and exacerbation.
ICS work through a multifaceted mechanism of action. They suppress the inflammatory response caused by the proliferation of TH cells. They also reduce the transcription of the IL-2 gene, which is involved in the...
