Immunologic Diseases

review of structure and function
Review of Structure and Function
  • Immunity means the resistance to, or protection from an individuals environment.
  • As simple as that sounds, there are multiple ways this is achieved.
immunity
Immunity
  • Innate immunity
    • Skin
    • Inflammatory responses
  • Adaptive immunity
    • Internal chemical reaction to foreign substances (antigens) in the body
incomplete and complete antigens
Incomplete and Complete Antigens
  • Incomplete Antigens (Haptens)
    • These cannot trigger an immune response unless coupled with another antigen.
  • Complete antigens
    • These can induce an immune response and also interact with the antibodies produced by an immune response.
t cells and b cells
T cells and B cells
  • B lymphocytes are capable of developing into plasma cells to produce immunoglobins.
    • They originate from the lymphoid tissue of the GI tract and bone marrow
t cells and b cells1
T cells and B cells
  • T lymphocytes are produced by the thymus, and are broken down further
    • T-helper Cells
    • T-suppressor Cells
    • Cytotoxic T cells
t cells
T cells
  • Antigens are broken down and presented to T cells.
  • When this occurs, the body will stimulate B cells to create antibodies (T-helper cells), suppress the production of antibodies (T-suppressor cells), or direct kill the foreign cell (Cytotoxic T-cell)
immunoglobins
Immunoglobins
  • IgG
    • Most abundant, very active in bacterial infections
  • IgM
    • Controls bacteria and clumping of large foreign substances
  • IgA
    • Secreted in bodily fluids
immunoglobins1
Immunoglobins
  • IgE
    • Histamine release in the allergic response
  • IgD
    • Antigen receptor on the surface of mature B cells
classification of immunologic diseases
Classification of Immunologic Diseases
  • Immune deficiency disease
    • Too little response to foreign agents
    • T-cell or B-cell deficiencies
  • Hypersensitivity reactions
    • Too much response to antigens
    • Types I-IV
hypersensitivity responses
Hypersensitivity Responses
  • Type I
    • Anaphylactic-atopic allergy
  • Type II
    • Cytotoxic-type hypersensitivity
hypersensitivity responses1
Hypersensitivity Responses
  • Type III
    • Immune complex or Arthus-type
  • Type IV
    • Delayed hypersensitivity
most frequent type i hypersensitivities
Most Frequent Type I Hypersensitivities
  • Allergic rhinitis
    • This is considered a chronic reaction
  • Allergic asthma
    • This is also considered a chronic reaction with acute episodes as well
most frequent type i hypersensitivities1
Most Frequent Type I Hypersensitivities
  • Anaphylactic reactions
    • This is an acute reaction
common type ii iii and iv hypersensitivities
Common Type II, III, and IV Hypersensitivities
  • Type II (Cytotoxic)
    • Transfusion reactions
    • Erythroblastosisfetalis
  • Type III (Immune complex)
    • Serum sickness
    • Cryoglobulinemia
common type ii iii and iv hypersensitivities1
Common Type II, III, and IV Hypersensitivities
  • Type IV (Delayed)
    • Allergic contact dermatitis
    • Poison Ivy
diagnosis
Diagnosis
  • Type I
    • Allergy skin testing
  • Type II
    • Direct Coombs test
diagnosis1
Diagnosis
  • Type III
    • Immunofluorescence
  • Type IV
    • Injection under the skin, or a skin patch test.
immune deficiency diseases
Immune Deficiency Diseases
  • Primarily manifested by an increased susceptibility to infections.
  • B-cell system deficiency
    • Pyogenic pneumonia
  • T-cell system deficiency
    • Absence of skin reactivity
autoimmune diseases
Autoimmune Diseases
  • Systemic Lupus Erythematosus (SLE)
    • A relatively common auto-immune disease
    • Usually affects multiple organ systems
