Expert Review of Clinical Immunology
|May 24, 2017
Summary
New allergen preparations and delivery methods are improving the safety and efficacy of allergen immunotherapy (AIT), offering a better treatment for chronic Type-1 allergies.
Area of Science:
- Allergy and Immunology
- Immunotherapy
- Pharmacology
Background:
- Type-1 allergies are common chronic diseases.
- Allergen immunotherapy (AIT) is a key treatment, but carries risks of severe reactions.
- Developing safer AIT is crucial.
Purpose of the Study:
- To review clinical applications of novel approaches in AIT.
- To assess methods for improving AIT safety and efficacy.
- To explore new allergen preparations and delivery routes.
Main Methods:
- Structured literature search of Medline and Pubmed.
- Inclusion of guidelines and Cochrane meta-analyses.
- Review of clinical use of new AIT approaches.
Main Results:
- Novel allergen preparations (allergoids, recombinant allergens) enhance subcutaneous and mucosal AIT.
- New application routes (intralymphatic, epicutaneous) are being explored alongside established sublingual immunotherapy.
- Immune-modifying agents (e.g., Virus-like particles, CpG-motifs) and adjuvants (e.g., MPL, aluminum hydroxide) show promise in directing immune responses towards tolerance.
Conclusions:
- New allergen extracts and delivery methods can significantly improve AIT safety and efficacy.
- These advancements may transform future AIT practices.
- Further research into novel preparations and delivery systems is warranted.

01:25Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
2.1K
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...

Lower respiratory tract disorders present challenges that often require skilled and nuanced approaches for effective management. Common ailments, such as asthma and chronic obstructive pulmonary disease (COPD), have prompted the development of intricate treatment strategies involving bronchodilators and anti-inflammatory drugs, each tailored to ease breathing and revitalize the lungs.

01:30Allergic Reactions: Anaphylaxis
80
Anaphylaxis is a severe, life-threatening hypersensitivity reaction mediated by Immunoglobulin E (IgE) antibodies. When IgE binds to allergens, it triggers the release of mediators– histamine, leukotrienes, and prostaglandins from mast cells and basophils. These mediators cause vasodilation, edema, and inflammation, leading to various symptoms.The primary allergens causing anaphylaxis include food items (e.g., peanuts, shellfish), drugs (e.g., penicillin, asparaginase, corticotropin,...

2.1K
Adrenergic agonists have diverse therapeutic uses across various medical conditions and emergencies.
Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.

1.8K
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...
