Diagnostic Criteria for Common Variable Immunodeficiency (CVI)

Probable

Male or female patient who has a marked decrease (at least 2 SD below the mean for age) in serum IgG and IgA and fulfills all of the following criteria:

  1. Onset of immunodeficiency at greater than 2 years of age.

  2. Absent isohemagglutinins and/or poor response to vaccines.

  3. Defined causes of hypogammaglobulinemia have been excluded.

Possible

Male or female patient who has a marked decrease (at least 2 SD below the mean for age) in one of the major isotypes (IgM, IgG, and IgA) and fulfills all of the following criteria:

  1. Onset of immunodeficiency at greater than 2 years of age.

  2. Absent isohemagglutinins and/or poor response to vaccines.

  3. Defined causes of hypogammaglobulinemia have been excluded.

 

Differential Diagnosis of Hypogammaglobulinemia

Drug induced

  • Captopril

  • Carbamazepine

  • Glucocorticoids

  • Fenclofenac

  • Gold salts

  • Penicillamine

  • Phenytoin

  • Sulfasalazine

Genetic disorders

  • Ataxia telangiectasia

  • Autosomal forms of Severe Combined Immunodeficiency (SCID)

  • Hyper IgM immunodeficiency

  • Transcobalamin II deficiency and hypogammaglobulinemia

  • X-linked agammaglobulinemia

  • X-linked lymphoproliferative disorder (EBV associated)

  • X-linked SCID

  • Some metabolic disorders

Chromosomal anomalies

  • Chromosome 18q2 syndrome

  • Monosomy 22

  • Trisomy 8

  • Trisomy 21

Infectious diseases

  • HIV

  • Congenital rubella

  • Congenital infection with CMV

  • Congenital infection with Toxoplasma gondii

  • Epstein–Barr virus

Malignancy

  • Chronic lymphocytic leukemia

  • Immunodeficiency with thymoma

  • Non-Hodgkin lymphoma

  • B cell malignancy

Systemic disorders

  • Immunodeficiency caused by hypercatabolism of immunoglobulin
