44
- Altered immune response to an antigen that results
- Response may be bothersome or life threatening
- Classified by type of response, immediate or delayed, organ system, or allergen
Hypersensitivity
45
characterized by rapid development of symptoms after exposure to an antigen. Anaphylaxis is the most severe form
Type I, or immediate hypersensitivity
Rapid development of symptoms after exposure to an antigen
Ie Anaphylaxis
46
Involves the rupture of cells targeted by the immune response. A common example is transfusion reactions.
Type II, or cytotoxic hypersensitivity
Involves rupture of cells targeted by the immune response.
Ie. transfusion reactions!
47
Includes inflammatory response in the targeted tissues that leads to tissue damage. Autoimmune disease often involve this type of reaction.
Type III, or immune complex reaction.
Includes inflammation response in the targeted tissues that lead to tissue damage.
Ie. Autoimmune diseases
48
Characterized by tissue damage at the site of antigen contact 24-48 hours after exposure. Contact dermatitis is an example.
Type IV, or delayed-type hypersensitivity
Characterized by tissue damage @ the site of antigen contact 24-48 hrs after exposure.
Ie. contact dermatitis
49
```
Type I; IgE mediated; Local or Systemic
Type II; IgG or IgM; Cytotoxic
Type III; Immune complexes (IgG or IgM antibody and antigen)
Type IV; Delayed; T-Cell/Macrophage
*HIV, Rh. Arthritis
Stimulatory (Type V)
```
Types of hypersensitivity Reactions
Humoral
Stimulating specific targets, antibodies bind to target cell & stimulate. "Turned-on"
Ie. contact with foreign antigen stimulates B cells.
50
IgE-mediated hypersensitivity; ***poison ivy
-common hypersensitivity. Trigger when allergen interacts with free IgE
-allergens can be ingested in food, injected, inhaled, or absorbed.
*Can be local or systemic (atopic or anaphylactic)
-Local mediators remain confined to a local area
-Allergens cause hay fever, rhinitis, asthma.
-Mosquito bite
-Hives
*Systemic-Mediators are released systemically.
-Anaphylactic shock
(Epi pen, epinephrine into thigh) *acts only to stabilize until get to hospital) Very small window; anaphylactic shock. keep airway open, Remove allergen
Type I
51
*Release of histamine Leads to
-Vasodilation in small arteries and capillaries
-Increased capillary permeability
-Smooth muscle contraction, (muscle tightens, throat closes up)
-Bronchial constriction; can't breath, bronch seizing up)
*Most severe form is anaphylaxis!
-commonly assoc. with ABX and more recently Latex.
1st 5/10 mins after 1st time taking med; Abx. systemic; rash on skin
Type I
52
- Erythema and sometimes angioedema of the eyes, lips or tongue.
- First feelings of uneasiness, apprehension, weakness, and impending doom.
- Pruritus & urticaria
- Edema and swelling, followed rapidly by wheezing, dyspnea, cyanosis, and circulatory collapse requiring immediate emergency treatment.
- Maintenance of airway is a priority; tongue blocked; get out of way of opening.
- ABX reaction possible; take history; hospitalization, 1st time taking abx. bc. no previous exposure
Anaphylaxis
| Can be fatal!
53
```
First assess respiratory function
Oxygen
CPR may be needed.
Epinephrine (1: 1000) 0.3 to 0.5 ml IV or SubQ
Antihistamines treat angioedema and urticaria.
Treat bronchospasm
IV fluids
Monitor VS (BP/Resp)
Treat underlying cause
```
Anaphylaxis Intervention
54
Type II (Cytotoxic) hypersensitivity
- IgG or IgM-type antibodies form to a cell-bound antigen
- Antibodies bind with antigen
- (Exogenous or Endogenous Stimulation)
- Examples of exogenous antigen reaction
* foreign tissue or cells
* Drug reaction PO meds
* Withdrawal of antigen stops hemolysis; remove antigen
Type II
55
Special autoantibodies directed against self cells that have some form of foreign protein attached to them. Self cells destroyed by lysis or phagocytosis. (pacman)
-clinical examples include:
*hemolytic anemia
*thrombocytopenic purpura
*hemolytic transfusion reactions
*Good pasture's syndrome; body mistakes and generates
lungs to kidneys; lung/renal damage
Type II Cytotoxic Hypersensitivity
56
Blood Transfusion
*IgG or IgM antibodies attach to a cell-bound antigen
*Complement cascade destroys target cell
*Stop Transfusion, if not reaction will be worse.
***Shut off pump if having a reaction!!!
riders, turn beat red; shooting pain, fever, local irritants (10-15 min) usual reaction. Do next set of vitals in 15 mins.
Drug reaction
*Drug forms antigenic complex on blood cell surface.
*Resulting reaction destroys cells leading to hemolytic anemia
*Discontinuing drug stops the reaction
-check for any itching, swelling reaction.
Cell lysis (destruction)
Examples of Type II
57
- Endogenous antigen forms on surface of tissue
- Reaction destroys the tissue
- Results in autoimmune disorders
- Myasthenia Gravis; disease of myelin sheath tissue. mistake and generates/misfiring nerves or non-firing.
* Severe weakness caused by circulating antibodies that block Acetylcholine receptors @ the post synaptic neuromuscular junction.
- Goodpasture's syndrome
* The body mistakenly generates antibodies against lung and renal tissue producing lung damage and renal failure.
Examples of Type II
58
- remove offending drug or blood product.
- Plasmapheresis-fresh plasma
- Treatment is symptomatic
- Complications can be life threatening
* respiratory failure
* Renal failure
* Hemolytic crisis
Treatment of Type II Cytotoxic Reactions
59
* Results from formation of IgG or IgM antibody-antigen immune complexes in circulatory system
* These circulating complexes usually lodge in small blood vessels.
* Local
- immune complex accumulates in the glomerular basement membrane of the kidneys.
ex. Streptococcal infection or with systemic lupus erythematosus glomerulonephritis
* Systemic
- Fever urticaria, rash, arthralgia, lymphadenopathy, myalgia
Type III; Immune complex-mediated
60
*Serum Sickness; often seen when horse or rabbit serum injected. Self limiting.

*Rheumatoid Arthritis; primarily affects synovial joints causing pain and deformity.[Corticosteriods]
-Multiple treatments: medication; harsh on body, carcinogenics; lupus.
Autoimmune diseases are not curable.
1-3 weeks after injection; reaction.
Type III; Immune complex Mediated
61
* T cell and macrophage mediated rather than antibody mediated; nothing to do with IgG or IgM
* Local collection of lymphocytes and macrophages causes edema, induration, ischemia, and tissue damage at the site (local site)
* Turberculin testing POS have induration and redness in 8-12 hrs. (PPD). Decrease just having reaction with injection negative. Bump positive. (induration) Have to touch
* Contact dermatitis such as poison ivy
* Latex allergy
- Can process to type I reaction (IgE response); unknown Latex allergy and put on; can have IgG response.
- Insect stings
- Organ transplantation rejection.
- Sarcoidosis-Fibrosis in lung tissue; decrease function of organ. Clumping tissue; grows in organ. Brandylonas. genetic; extreme reaction to antigens.
Type IV: Delayed Hypersensitivity Reactions
62
- Immunotherapy/Desensitization/Allergy shots build IgG.
- Epinephrine
- Corticosteriods & Anti-inflammatory agents can reduce discomfort.
- Histamine blockers: Benadryl of minimal benefit because Histamine is not the main mediator however, can help with sleep and itching.
Type IV: Interventions
63
-Stimulatory hypersensitivity; antibodies are produced with the property of stimulating specific cell targets (humoral immunity)
-B cell mediated immunity; activated when in contact with antigen can excrete memory cells or antibodies; made in bone marrow.
-Autoantibodies bind to target cell and stimulate cells.
-Excess stimulation of a normal cell surface by an autoantibody, results in a continuous "turned-on" state for the cell.
-May cause uncontrolled secretion of hormone.
*the feedback mechanism is lost. Sends thyroid over stimulations; Grave's disease; hyperthyroidism
*Grave;'s disease (hyperthyroidism)
