1. Exam Coverage
Content Areas:
• Week 1: Immunological Pathologies
• Week 2: Hematological and Cardiovascular Pathologies
• Week 3: Pulmonary Pathologies
• Week 4: Urinary System Pathologies
2. Key Concepts to Study
Alterations in Immunity and Inflammation:
• Pathophysiology of the four types of hypersensitivity reactions
ACID
Type I
Immediate (Anaphylaxis) – uses IgE antibodies – antibodies bind to mast
cells and basophils- releases histamines based on prior exposure to the allergen.
Results to vasodilation, bronchoconstriction, hives, edema and anaphylaxis
(severe).
Hay fever, insect bites, food/drug allergies, asthma
Type 2
Antibody-Mediated (Cytotoxic) -IgG/IgM antibodies – bind to antigens on
the surface of host cells – blood cell, platelets, tissues – activates the complement
system – leads to lysis – formation of the membrane attack complex.
Phagocytosis may occur.
transfusion reactions, autoimmune hemolytic anemia, Graves Disease, Rh
Incompatibility, MG
Type 3
Immune-Complex -IgG/IgM. formation of immune complex that deposit
in the tissues. Activates the complement system – leads to inflammation and
tissue damage.
SLE, RA, serum sickness, vasculitis, glomerulonephritis
Type 4
Delayed (Cell Meditated)- T-cells (CD4, TH1). Antigen presenting cells
capture the antigen and present in T helper cells which become sensitized and
activate during subsequent exposure. Upon re-exposure the t cell releases
cytokins – activation of immune cells- causes inflammation and tissue damage.
, Contact dermatitis, TB, chronic transplant rejection, MS
• Prototype diseases that reflect each of the four types of hypersensitivity (i.e. Type IV-
contact dermatitis) and signs and symptoms
Type I – Immediate (Anaphylaxis)
Cause: Allergens (food/meds/hay fever, asthma, dermatitis)
Components: IgE, Mast Cells, histamine
S/S –
Sudden onset wheezing
Hives hypotension, tachycardia, dizziness
Swelling nausea, vomiting, diarrhea
Shock (severe)
Type 2 -Cytotoxic (Antibody Mediated)
Cause: receiving incompatible blood type, hemolytic anemia, Graves Disease,
MG
S/S –
Fever hypotension, jaundice
Chills hemoglobinuria
Back/flank pain renal failure/shock (severe)
Type 3 -Immune-Complex
Cause: Autoimmune response
Components – IgG/IgM, antibody-antigen components, complement, RA, serum
sickness, glomerulonephritis, hypersensitivity pneumonitis, TB, MS DMI
S/S-
Butterfly rash (Malar rash) renal involvement
Fatigue/fever neurological sympotms
Joint pain serositis (pericarditis/pleuritis)
Photosensitivity
Type 4 – Delayed Type
Cause : skin contact with allergen (poison ivy, nickel, latex)
Components -T cells, cytokins, macrophanges
S/S
Red, itchy rash localized swelling
Blisters
Scaling/thickened skin (with chronic exposure)
• Treatment options for diseases under each hypersensitivity category
Type I – Immediate Type (Anaphylaxis)
Anaphylaxis Treatment
Epi Antihistamines
Oxygen Corticosteriods
IV fluids Airway Management
Allergic Rhinitis Treatment
, Antihistamines (oral and intranasal) Allergy avoidance
