5 IMMUNE SYSTEM defect IMMUNE DEFICIENCY Increased susceptibility to infection

6 IMMUNE DEFICIENCY PRIMARY CONGENITAL humoral cellular combined humoral and cellular SECONDARY ACQUIRED malnutrition malignancy immunosuppresive drug infection of cell of immune system

7 IMMUNE DEFICIENCY QUALITY Function QUANTITY Number

8 PRIMARY IMMUNE DEFICIENCY Caused by defect in Innate immunity CELLULAR Phagocytic dysfunction disease HUMORAL Complement defficiency Adaptive immunity CELLULAR T cell defficiency B cell defficiency T & B cell defficiency HUMORAL Antibody

9 IMMUNE DEFICIENCY

10 IMMUNE DEFICIENCY Quantity Absolute lymphocyte count general assessment of T cell presence T cell enumeration measure number of circulating T cells T cell subset enumeration CD4+ (helper), CD8+ (cytotoxic)

11 IMMUNE DEFICIENCY Quality Delayed hypersensitivity skin test to recall antigens (PPD, Candida) in vivo ability of T cell to respond to previously encounter antigen Lymphocyte reaction to mitogen or antigen Cytokine production T cell ability to secrete lymphokine Proliferation

12 IMMUNE DEFICIENCY Quantity B cell enumeration measure number of circulating B cells

13 IMMUNE DEFICIENCY Quality Ig quantitation (IgG, IgA, IgM) general assessment of B cell function Isohemagglutinin titer (anti-a & -B) general indicator of IgM production Specific Ab level following immunization (tetanus toxoid, typhoid, paratyphoin) in vivo ability to response to a known Ag

14 IMMUNE DEFICIENCY Phagocytic dysfunction Complement defficiency

15 IMMUNE DEFICIENCY Quality Motility Chemotaxis Recognition & adhession adhession molecules (integrin, selectin ligand) Ingestion Degranulation Intracellular killing nitroblue tetrazolium superoxide production Quantity Absolute count neutrophil monocyte

16 IMMUNE DEFICIENCY Quality Complement activity Quantity Complement level Total hemolytic complement assay (CH50)

17 IMMUNE DEFICIENCY Recurrent bacterial infection B cell count Neutrophil count Complement level Antibody level Specific antibody responses Complement activity Neutrophil function QUANTITATIVE NORMAL QUALITATIVE Severe viral or fungal infection Lymphocyte count T cell count T cell subset DTH
