Non-IgE-mediated food allergies, affecting children and adults, involve immune reactions without IgE antibodies. Diagnosis often requires food challenges or endoscopies due to a lack of biomarkers.
Area of Science:
- Immunology
- Gastroenterology
- Allergy
Background:
- Food allergies are rising, affecting 8% of children and 2% of adults.
- Non-IgE-mediated food allergies involve immune responses to food proteins without IgE antibodies.
- These allergies primarily affect the gastrointestinal tract, presenting as acute (FPIES) or chronic conditions (EoE, FPIAP).
Purpose of the Study:
- To review the current understanding of non-IgE-mediated food allergies.
- To highlight the diagnostic challenges and treatment strategies for these conditions.
- To emphasize the need for further research into the mechanisms and biomarkers of non-IgE food allergies.
Main Methods:
- Literature review of existing studies on non-IgE-mediated food allergies.
- Analysis of diagnostic criteria and treatment approaches.
- Discussion of the immunological mechanisms involved.
Main Results:
- Non-IgE-mediated food allergies are a heterogeneous group of disorders.
- Diagnosis often relies on invasive methods like food challenges and endoscopies.
- Effective treatments include dietary modifications and medications like steroids and PPIs.
Conclusions:
- Non-IgE-mediated food allergies represent a significant and growing health concern.
- Validated biomarkers for diagnosis and monitoring are critically needed.
- Further research is essential to elucidate the underlying mechanisms and improve patient outcomes.

Hypersensitivity reactions are categorized into four types: Type 1, Type 2, Type 3, and Type 4. Each type has a distinct mechanism...
Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
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...

Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
