Hypersensitivities
6.2K
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...

Allergic Drug Reactions
1.3K
Allergic reactions related to drugs are hypersensitivity responses driven by the immune system and bear no connection to the drug's therapeutic action. While drugs in isolation do not trigger an immune response, they can interact with endogenous proteins to form antigens. These antigens stimulate lymphocytes to produce antibodies. IgE-type antibodies attach themselves to mast cells. Upon subsequent exposure to the same stimulus, the antigen-antibody interaction is initiated, unleashing...

Desensitization and Tachyphylaxis
2.9K
Tachyphylaxis is described as a rapid decrease in response to a drug after repeated or continuous administration of the same drug dose. It is a phenomenon where the body becomes less responsive to a particular substance or intervention over time, requiring higher doses or stronger interventions to achieve the same effect. It results from adaptive changes in the body's receptors, signaling pathways, or physiological processes that occur in response to prolonged exposure to a stimulus.

Antibody Structure

Overview
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.
The Y-Shaped Structure of Antibodies Consists of Four Polypeptide Chains
Antibodies consist of four polypeptide chains: two identical heavy...

Summary
Tick anaphylaxis is rare in Asia. This case highlights a severe allergic reaction in a man after removing a tick, emphasizing cautious removal techniques, especially for those with known allergies.
Area of Science:
- Allergy and Immunology
- Toxicology
- Dermatology
Background:
- Tick anaphylaxis is a rare but serious allergic reaction.
- Awareness of tick anaphylaxis is particularly low in Asian countries.
- This report details a unique case triggered by the physical removal of a tick.
Observation:
- A 66-year-old man presented with symptoms of anaphylactic shock.
- The reaction occurred approximately 30 minutes after he manually removed a swollen tick from his toe.
- Initial symptoms included pruritus followed by chest discomfort and severe hypotension.
Findings:
- The patient was diagnosed with anaphylactic shock (systolic blood pressure 60 mmHg).
- Immediate treatment with intramuscular adrenaline was administered.
- This represents the first reported case of tick anaphylaxis triggered by tick removal in Asia.
Implications:
- Tick removal should be performed carefully, avoiding pressure on the tick's body.
- Physicians should consider tick anaphylaxis in patients presenting with allergic reactions, especially after potential tick exposure.
- Increased awareness and education regarding tick-borne allergies are crucial in endemic regions.
