Summary

This study found antibody deficiency disorders, particularly selective IgA deficiency, are the most common immunodeficiencies. Cellular deficiencies presented higher mortality rates, highlighting the need for advanced diagnostic and treatment centers.

Area of Science:

  • Immunology
  • Genetics

Background:

  • Immunodeficiencies are common genetic disorders.
  • Accurate diagnosis and treatment are crucial.

Purpose of the Study:

  • To analyze the prevalence of different immunodeficiency types in a patient cohort.
  • To identify risk factors associated with mortality in immunodeficient patients.

Main Methods:

  • Retrospective analysis of 83 patients diagnosed with immunodeficiency.
  • Categorization based on affected immune mechanisms: antibody deficiency, unspecific mechanisms, and cell-mediated immunity.

Main Results:

  • Antibody deficiency disorders were most prevalent (74.6%), with selective IgA deficiency being the most common humoral defect.
  • Abnormalities of unspecific mechanisms occurred in 13.3% and cell-mediated deficiencies in 9.6% of patients.

  • Overall mortality was 6%, with a higher rate observed in patients with cellular deficiencies.

    • Conclusions:

    • Antibody deficiencies, especially selective IgA, are the most frequent immunodeficiencies.
    • Cellular deficiencies are associated with increased mortality.
    • Development of advanced technology centers is essential for appropriate diagnosis and treatment of immunodeficiencies.
