◉ What are the four types of hypersensitivity reactions?
Answer: 1. Type 1: Allergic/Anaphylactic/Atopic 2. Type 2: Cytotoxic
3. Type 3: Immune Complex 4. Type 4: Delayed.
◉ What characterizes Type 1 hypersensitivity reactions?
Answer: Rapid release of proinflammatory mediators like histamine,
leukotrienes, prostaglandins, and cytokines in response to allergic
exposure.
,◉ What are the physiological manifestations of Type 1 hypersensitivity
reactions?
Answer: Vasodilation, bronchial smooth muscle contraction, and mucus
production.
◉ What is the prototype disease for Type 1 hypersensitivity?
Answer: Anaphylaxis, Allergic Rhinitis, Asthma, Food Allergies.
◉ What are the signs and symptoms of Anaphylaxis?
Answer: Rapid onset; difficulty breathing, hypotension, hives, wheezing,
angioedema, and possibly shock.
◉ What are the treatment options for Anaphylaxis?
Answer: Epinephrine (IM), airway management, oxygen and IV fluids,
antihistamines, corticosteroids.
◉ What is the mechanism behind Type 2 hypersensitivity reactions?
Answer: IgG or IgM antibodies target antigens on cells, leading to cell
destruction via complement activation or phagocytosis.
◉ What is an example of a Type 2 hypersensitivity reaction?
Answer: Heparin-induced thrombocytopenia (HIT) and hemolytic
transfusion reactions.
, ◉ What are the primary effector cells in Type 2 hypersensitivity
reactions?
Answer: Macrophages.
◉ What are the signs and symptoms of Type 2 hypersensitivity
reactions?
Answer: Fatigue, pallor, jaundice, tachycardia, shortness of breath,
elevated bilirubin, low hemoglobin and hematocrit.
◉ What is the first-line treatment for Type 2 hypersensitivity reactions?
Answer: Corticosteroids (prednisone).
◉ What is the prototype disease for Type 2 hypersensitivity?
Answer: Autoimmune Hemolytic Anemia, Grave's Disease.
◉ What is the pathophysiology of Type 3 hypersensitivity reactions?
Answer: Immune complex-mediated reactions.
◉ What is the role of mast cells in Type 1 hypersensitivity reactions?
Answer: They are the primary effector cells responsible for initiating
and mediating the reactions.
◉ What are common treatments for Allergic Rhinitis and Asthma?
