    5. Radiation Therapy
    6. HIV Infection or AIDS
      1. Presents similarly to T-Cell Immunodeficiency Disorder

IV. Causes: Antibody or humoral (B-Cell Disorder): 78% of cases in U.S. (55% in Europe)

  1. General
    1. Present after 3 months of age (when maternal antibodies are no longer present)
    2. B Cell deficiency or maturation defect results in Antibody deficiency
    3. Recurrent respiratory (ears, sinus, lungs) infections with encapsulated organisms
      1. Streptococcus Pneumoniae
      2. Haemophilus Influenzae
  2. No B-Cells: Agammaglobulinemia
    1. X-Linked Agammaglobulinemia or XLA (84% of Agammaglobulinemia cases in Europe)
      1. Bruton Tyrosine Kinase defect (Btk gene) results in defective B-Cell maturation
      2. Absent peripheral B-Cells results in very low serum IgG, IgA and IgM
      3. Infants may have no Tonsils or Lymph Nodes on exam
      4. Severe respiratory infections with Encapsulated Bacteria (e.g. Pneumococcus, H. Influenzae)
      5. Chronic Diarrhea (echoviruses and coxsackie virus), recurrent varicella
  3. Decreased B Cells or Antibody: Hypogammaglobulinemia
    1. IgA Deficiency (30% of U.S. cases and most common B-Cell Disorder overall in U.S.)
      1. Low levels or absent IgA
      2. Prone to respiratory or gastrointestinal infections
      3. May be associated with IgG2 or IgG4 deficiency
    2. IgG Subclass Deficiency of IgG2, IgG3, IgG4 (26% of U.S. cases)
    3. Common Variable Immunodeficiency or CVID (15% in U.S. and 46% in Europe of cases)
      1. Bimodal onset in preschool and in young adults
      2. Two Immunoglobulin subtypes are low (typically including Low total IgG, as well as IgM and IgA)
      3. B-Cells may be decreased in number and have defective function (T Cells may also be defective)
      4. Similar to X-Linked Agammaglobulinemia, but more mild
      5. Ear, sinus and lung infections occur as with other Antibody Disorders (e.g. Pneumococcus, H. Influenzae)
      6. CVID also present with malabsorption from Infectious Diarrhea
        1. Examples: C. difficile, Giardia, Salmonella, Campylobacter, Yersinia

      1. CD40 Ligand deficiency (most common cause, X-Linked)
      2. T-Lymphocytes are unable to trigger B-Cells to switch Immunoglobulin production of IgM to IgG, IgA and IgE
      3. IgM levels increase, but other Antibody levels are deficient
      4. Results in recurrent and severe infections (including opportunistic infections)
      5. Results in increased malignancy risk

V. Causes: T-Cell Disorders (9-10% of Primary Immunodeficiency in both Europe and U.S.)

  1. See HIV Infection (or AIDS)

      2. False Positives 1.5% in term infants and 5% Preterm Infants in NICU (will requires re-testing)
  4. Ataxia Telangiectasia
    1. Combined humoral and cell-mediated Immunity deficiency
    2. Impaired DNA repair mechanisms result in IgA deficiency (and possibly IgG2 and IgE deficiency)
    3. Onset of Telangiectasia by age 3-6 years old
    4. Progressive Ataxia affecting disordered ambulation by age 10-12 years old
    5. Recurrent sinus and lung infections, autoimmune disorders and malignancy (e.g. Non-Hodgkin Lymphoma)
  5. Wiscott-Aldrich Syndrome
    1. X-Linked disorder, typicalluy diagnosed around 21 months of age
    2. Classic triad of Thrombocytopenia, recurrent Otitis Media and Eczema (present in only 27% of cases)
    3. Thrombocytopenia with life threatening bleeding (GI Bleeding, Intracranial Bleeding) in up to 30% of children
  6. DiGeorge Syndrome (Velocardiofacial, Congenital Thymic Aplasia)

IX. Differential Diagnosis

  1. Asthma or atopic condition
  2. Cystic Fibrosis
  3. Secondary Immunodeficiency
    1. See Types section above

X. Labs

  1. Initial Screening
    1. Complete Blood Count with manual differential
      1. Screens for T-Cell Disorders and Phagocytic disorders
      2. See Absolute Lymphocyte Count discriminatory levels under T-Cell Disorders below
      3. Low Neutrophil Count (ANC <1500/mm3) may suggest cause for phagocytic disorder
    2. Serum Immunoglobulin levels
    3. Complement Levels
      1. Complement C3 (Intrinsic and Extrinsic Pathway Function)
      2. Complement C4 (Intrinsic Pathway Function, deficiency in 11% of SLE patients, 1% of U.S. population)
      3. CH50 (Entire Intrinsic Pathway Function)
    4. Peripheral Smear
      1. Howell-Jolly bodies suggests Asplenism
    5. HIV Test
      1. Age 18 months or older
        1. HIV Antibody testing is sufficient
      2. Age under 18 months
        1. Obtain HIV DNA PCR or HIV RNA at age 14-21 days, age 1 month and age 4-6 months
  2. Specific Immunodeficiency testing
    1. B-Cell function and Antibody Tests (Humoral Immunity)
      1. Step 1: Quantitative serum IgG, IgM, IgE and IgA levels
        1. IgG subclasses (IgG 1-4) are usually not helpful
        2. Low serum Immunoglobulin levels should prompt Serum Albumin testing
          1. Hypoalbuminemia (e.g. Proteinuria or malabsorption) may cause secondary Immunodeficiency
      2. Step 2: Response to Vaccine (if step 1 Immunoglobulin levels are low)
        1. Obtain pre-Vaccine titers
        2. Administer Vaccine
          1. Encapsulated organism Vaccines (H. Influenzae or Pneumococcus titers) if over age 2 years
          2. Tetanus, Rubella, Diptheria, or Mumps Vaccine at any age
        3. Measure post-Vaccine titers at 4 weeks (3 weeks if two or more prior same antigen Vaccinations)
          1. Expect 2 to 2.5 fold titer increase after Vaccination
          2. Failed titer increase suggests Humoral Immunodeficiency
    2. T-Cell Function Tests
      1. Absolute Lymphocyte Count (ALC, done in CBC)
        1. Unlikely if normal Lymphocyte Count
        2. Newborn: <3000/mm3 suggests T-Cell Disorder
        3. Infant or child with ALC at 2 S.D. below mean suggests T-Cell Disorder (especially SCID)
      2. Delayed-Type Hypersensitivity (age >1 year old)
        1. Intradermal Skin Test: Candida Albicans, Mumps or Tetanus
        2. Positive test rules-out T-Cell defects
        3. Most cost-effective test for T-Cell dysfunction
      3. Lymphocyte subset analysis (percentage estimates)
        1. T Cells (CD3, CD4, CD8)
        2. B Cells (CD19, CD20)
        3. Natural Killer Cells (CD16, CD56)
    3. Phagocytosis function tests
      1. Absolute Neutrophil Count (ANC) <1500/mm3
      2. Granulocyte function tests
      3. Flow cytometry for Neutrophil oxidative burst
    4. Complement function tests
      1. Total complement or CH50 (test when well)
      2. If abnormal, test alternative pathway (CH100 or AH50)
