Allergic Reactions

Allergic Reactions

Allergic Reactions: Anaphylaxis

Allergic Reactions: Anaphylaxis

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, heparin),...

Inflammatory Bowel Disease III: Crohn's Disease

Inflammatory Bowel Disease III: Crohn's Disease

Crohn’s disease is a chronic, relapsing form of inflammatory bowel disease characterized by segmental, transmural inflammation that can affect any part of the gastrointestinal tract. Its pathogenesis arises from a combination of genetic susceptibility, environmental exposures, epithelial barrier dysfunction, and immune dysregulation. Together, these factors lead to an exaggerated immune response against components of the gut microbiome.Genetic and Environmental InfluencesMultiple genetic...

Other Disorders of Digestive System

Other Disorders of Digestive System

The gastrointestinal tract is susceptible to various disorders. If the lower esophageal sphincter is damaged, stomach acid can flow back into the esophagus, causing irritation and inflammation of the lining. This condition is called gastroesophageal reflux disease (known as heartburn) and may cause chest pain and difficulty swallowing. In the stomach, prolonged use of nonsteroidal anti-inflammatory drugs like aspirin, chronic alcohol consumption, bacterial infections such as Helicobacter...

Asthma I: Introduction

Asthma I: Introduction

Asthma is a chronic inflammatory disorder of the airways characterized by variable airflow obstruction and heightened bronchial responsiveness to a wide range of triggers. The underlying inflammation leads to airway swelling, mucus hypersecretion, and smooth muscle constriction, all of which narrow the airway lumen and impede airflow. Clinically, asthma presents with recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing, symptoms that typically vary in intensity and...

Hypersensitivities

Hypersensitivities

Hypersensitivity, also known as a hypersensitivity reaction or allergic reaction, is a condition where the body's immune system reacts abnormally to a foreign substance. Such substances, that cause hypersensitivity are referred to as an allergen, could be something typically harmless to most people, like pollen or certain foods.
Types of Hypersensitivities
Hypersensitivity reactions are categorized into four types: Type 1, Type 2, Type 3, and Type 4. Each type has a distinct mechanism...

Summary

Pollen allergy (pollinosis) can cause respiratory issues and lead to plant food allergies through cross-reactivity. It may also directly cause digestive inflammation and eosinophilic esophagitis.

Area of Science:

Immunology
Allergology
Gastroenterology

Background:

Pollinosis involves respiratory symptoms from pollen inhalation in sensitized individuals.
Pollen allergy is linked to plant food allergies and digestive tract inflammation.
Cross-reactivity between inhaled pollen allergens and food allergens is a key mechanism.

Purpose of the Study:

To explore the connection between pollinosis and plant food allergies.
To investigate the role of pollen in digestive allergic conditions.
To understand the mechanisms linking airway and digestive tract allergic responses.

Main Methods:

Review of existing literature on pollinosis and allergic cross-reactivity.
Analysis of the impact of geographical and dietary factors on pollen-food allergy patterns.
Examination of the immunological pathways involved in pollinosis-related digestive inflammation.

Main Results:

Pollinosis can precede or coincide with plant food allergies due to shared allergens.
Pollen exposure can directly trigger digestive inflammation, including eosinophilic esophagitis.
The prevalence and severity of plant food allergies are influenced by local pollination and dietary habits.

Conclusions:

Pollinosis is a significant factor in the development and manifestation of plant food allergies.
Mechanisms beyond simple cross-reactivity link pollinosis to digestive allergic diseases.
Systemic allergic responses in pollinosis can impact the digestive tract, highlighting the airway-gut connection.
