1 Immunopathology. Immunotherapy and immuno-prophylaxis.
Immune preparations: vaccines, sera, and immunoglobulins Vinnitsa National Pirogov Memorial Medical University / Department of microbiology Vinnitsa National Pirogov Memorial Medical University / Department of microbiology

2 Immunopathology Immunopathology deals with pathological states or human diseases that result from inadequate immune system reaction to antigens

3 Classification of the immunopathological states
Hypersensitivity (allergy) Antibody-mediated hypersensitivity Cell-mediated hypersensitivity Autoimmune diseases Immunodeficiency

4 Classification of hypersensitivity
Immediate (anaphylactic) hypersensitivity Cytotoxic hypersensitivity Immune-complex hypersensitivity Delayed (cell-mediated) hypersensitivity

5 Type I: Immediate hypersensitivity

6 Type II: Cytotoxic hypersensitivity

7 Type III: Immune complex hypersensitivity

8 Type IV: Delayed (cell-mediated) hypersensitivity

9 Mechanism of contact dermatitis development
Allergic skin test

10 Immune status assay WBC count: Titer of complement, phagocytosis data
Γ-globulin Bactericidal activity of the skin Specific tests

11 Secondary immunodeficiency
May be associated with: Malnutrition and vitamin deficiency Severe and long-lasting somatic illness Malignancy Therapy with immunosuppressive drugs Hormonal disoders: diabetes mellitus, adrenal dysfunction, hypothyroidism Pregnancy Some virus infections (HIV, the flu, measles, herpetic infections such CMV and VEB, and others)

12 Artificial acquired immunity
Immune preparations (vaccines and sera) are used for immunization It allows to create herd immunity. High level of the herd immunity (a large proportion of the immune individuals in the community) may prevent epidemic infections such as diphtheria, poliomyelitis, measles, pertussis, tetanus, tuberculosis and others

13 Vaccines are the preparations of living or killed microorganisms or their products used for active immunization

14 Classification of the vaccines
Classic vaccines: Live vaccines Killed vaccines Subunit (chemical) vaccines Toxoids Modern vaccines: Vector vaccines Recombinant vaccines Synthetic subunit vaccines Ribosomal vaccines Liposomal ones DNA vaccines Antiidiotypic vaccines

15 Classification of the vaccines
Monovalent vaccines Polyvalent or associated vaccines

16 Preparations for passive immunization
Passive immunity can be used to prevent diseases when there is no time to acquire immune response through vaccination Immediate protection can be provided by administration of the immune sera, specific immunoglobulin, antitoxin, or pooled gamma-globulin (“readymade” antibody)

17 Classification of the serum preparations
Due to their action: Antibacterial (are used against plague, anthrax) Antiviral (are used against influenza, encephalitis, yellow fever ) Antitoxins (antidiphtheric, antitetanic, antibotilinic, antigangrenous) Immunotoxins Antiallergic Antitumoural (for experimental treatment of tumors) Antilymphocytic (are used for inhibition immune response after transplantation)

18 Classification of the serum preparations
Due to their employment: Therapeutic and prophylactic sera Diagnostic sera Modern immunoglobulin preparations: Bioglobulin, Gamma-venin, Veinoglobulin, Sandoglobulin, Intraglobulin

19 Hybridoma cells and monoclonal antibody

20 Immonotoxins

21 Immunosuppressive drugs
Cyclophosphamide Corticosteroids Cyclosporine Selsept (mophetil mycophenalite) Lephlunomide Antimetabolites (antitumor cytostatics) Selective immunosuppressive drugs

22 Immunostimulating drugs
Recombinant human cytokines Non-specific human immunoglobulins Natural stimulators obtained from animal thymus and embryo tissue Recombinant interferon

23 Immunostimulating drugs
Bacterial immunomodulators Plant immunomodulators Synthetic polypeptides
