Overview

Selective Immunoglobulin A( IgA) deficiency is the most common primary immunodeficiency and is defined as "serum level of IgA equal or below 7mg/dl in the presence of normal level of other immunoglobulins in individuals older than four years of age and in which other causes of hypogammaglobulinemia have been excluded.[1]

Historical Perspective

  • Immunoglobulin A was first discovered in the serum by Graber and Williams in 1953.
  • Within 10 years, the first cases with selective IgA deficiency were identified in healthy as well as in patients with ataxia telangiectasia.[2][3]

Classification

Selective IgA deficiency can be classified based on either the laboratory values of B-cells subsets or the clinical phenotype of individuals with the condition.

Classification Based on Memory B cell Population

SIgAD can be classified based on the laboratory values of the B-cell subsets such as naive, IgM memory, switched memory or IgM+CD21- B cells in patients as compared to healthy individuals.[4]

SIgAD2

Classification Based on the Clinical Phenotype

  • Health related quality of life(HRQL)can be compromised by the severity of symptoms in patients with selective IgA deficiency. It is classified based on the clinical presentation of the patients suffering from it.[5][6][7]
Selective immunoglobulin A classification based on clinical phenotypes of the patients
  • About 60% of the patients have no clinical findings.
  • Care should be taken while transfusing blood or blood products
  • Regular monitoring i.e every 4-6 months is required as the disease may progress
  • Patient should be educated but no therapeutic intervention is required
minor infections Phenotype
  • About 12% of the patients have minor infection phenotype.
  • Quality of life ( QoL) both in physical and mental components are significantly decreased in patients with this phenotype.[8]
  • Infections are usually caused by viral or bacterial agents that normally resolves without any sequel but few patients have severe infections and need investigations for secondary immune defects such as IgG2 subclass deficiency or mannan-binding lectin.
Allergy Phenotype
  • About 15% of the patients fall under this category.
  • QoL is severely affected in patients of this group, particularly in the mental component.[9]
  • Allergic manifestations in this group of patients are more severe than in the general population so special consideration should be given to the prevention and treatment of these patients. Evaluations of serum IgE level, skin prick test and lung function test are suggested in these patients.
Autoimmune Phenotype
  • There is an evidence of reduced proper mental and physical function affecting the QoL in patients with SIgAD.[10]
  • Among the autoimmune disorders, idiopathic thrombocytopenic purpura and autoimmune hemolytic anemia are more common in patients with IgA deficiency requiring blood or blood product administration frequently which should be performed with caution.
  • Based on the concurrence of autoimmune disorders with SIgAD, screening of IgA levels should be considered. In patients with SIgAD, IgA-based serological diagnosis of autoimmunity is difficult, since these assays may usually be negative leading to underestimation of the prevalence of these diseases.
  • Other autoantibodies could be found in the serum of some patients with SIgAD without any clinical autoimmune manifestations such as antibodies against thyroglobulin, thyroid microsomal antigens, red blood cells, basement membrane, smooth muscle cells, pancreatic cells, cardiolipin, human collagen, and adrenal cells. Although the presence and certain level of these antibodies donot predict the development of disorders but could be suggestive of future disease.[11]
Severe symptoms Phenotype
  • A few percent of the patient with SIgAD develop both recurrent or severe infections and autoimmune disorders fall into severe symptoms phenotype.
  • there is an association with HLA predisposing haplotype, reduced memeory B cells and decrease Treg counts.
  • Severe phenotype of selective IgA deficency and Combined variable immunodeficiecny share common clinical feature, eviddence of development of both the disease in a single family and progression of SIgAD into CVID propose a common genetic background.
  • Mortality rate for this group is twice as compared to the general population.
  • It is proposed that the patient with this phenotype and the family history of both SIgAD and CVID perform the basic clinical and immunologic evaluation and regular follow-up examinations.


Pathophysiology

Pathogenesis

  • Several studies were carried out to establish the mechanism involved in selective IgA immunodeficiency but the exact pathogensis is still not clear.
  • SIgAD has been attributed to an intrinsic B cell lymphocyte defect, T cell abnormalities and most recently an impairment in cytokine regulation indicating that it is a heterogenous dysfunction.[12][13][14]
  • The most common pathological process involved in patients with selective immunoglobulin A deficiency is a maturation defect in B cells to produce IgA.[15]
  • Normally, the surface immunoglobulins are acquired in a sequential manner in B- cell differentiation. The first surface immunoglobulin to appear on B cells is IgM, as the cells mature they acquire surface IgD and sometimes IgA or IgG. A fully differentiated B cell performs a specfic function which means it would bear a specfic surface immunoglobulin.It is found that Patients with sIgAD have B cells arrested at a stage where they coexpress surface IgM, IgD as well as IgA and donot develop into IgA secreting plasma cells.[16].
  • The abnormality appears to involve stem cells as it can be passed on by bone marrow transplantation.[17]
  • Cytokine dysregulation such as lack of IL-4, IL-6, IL-7, IL-10, TGF-b and most recently IL-21 is suggested to play a role in SIgAD[14][18]

Genetics

  • SIgAD is linked to several genetic abnormalities but whether they are involved in its causation is yet to be established. one of those malformations is a mutation in tumor necrosis factor(TNF) family member "transmembrane activator and calcium-modulator and cyclophilin ligand interactor"(TACI), a molecule responsible for isotype switching in B-cells.[19]

Associated Conditions

Diseases Associated with IgA deficinecy
Combined Variable Immunodeficiency
  • Common genetic basis has been proposed for IgA deficiency and common variable immunodeficiency by their existence in the members of the same family and the underlying B cell defect. [20]* IgA deficiency may progress into combined variable immundeficinecy.[21]
Autoimmune disorders
  • Several autoimmune diseases have been associated with SIgAD.[22][23]
  • The most common of them are:
    • Celiac disease
    • Type 1 diabetes myelitis[24]
    • Inflammatory bowel disease
  • Other less common conditions associated are:
    • Graves Disease
    • Rheumatoid arthritis
    • Systemic lupus erythematosus
    • Mysthenia gravis
    • Ulcerative colitis
    • Hyperthyreosis
    • Idiopathic juvenile arthritis
    • Hypothyreosis
    • Idiopathic Pulmonary Hemosiderosis[25]
Ataxia Telangiectasia[26]
Carcinomas
  • There is an increased risk of cancer specifically of the gastrointestinal tract in adults.Though children with IgA deficiency are not at increased risk for cancers.[27][28]

  • Viral infections: such as Epstein-Barr virus, HIV, cytomegalovirus are other causes of hypogammaglobulinemia..
  • Side effect of certain medications: Some drugs include systemic glucocorticoids, phenytoin, and carbamazepine, have been associated with IgG deficiency.[77]
  • Other causes of primary humoral immunodeficiencies.
  • Smoking: may cause IgG2 subclass deficiency.[78]
  • Protein-losing conditions: enteropathies, nephrotic syndrome, burns, and other traumas may cause abnormal loss of immunoglobulins.
