Common variable immunodeficiency (CVID) is a primary immune disorder causing antibody deficiency and recurrent infections. Its exact cause remains unknown despite identified T cell and B cell defects, leading to delayed diagnosis in adults.

Area of Science:

  • Immunology
  • Primary Immunodeficiency Diseases

Background:

  • Common variable immunodeficiency (CVID) is a frequent primary immunodeficiency.
  • Hallmark is hypogammaglobulinemia, leading to recurrent bacterial infections.
  • Associated with inflammatory conditions, autoimmune diseases, and lymphomas.

Purpose of the Study:

  • To summarize the key features of CVID.
  • To highlight diagnostic challenges and unknown etiology.

Main Methods:

  • Review of existing literature on CVID.
  • Analysis of clinical manifestations and immunological findings.

Main Results:

  • Patients present with hypogammaglobulinemia and recurrent infections.
  • Delayed diagnosis is common, with most patients identified in adulthood.

  • Known defects include T cell dysfunction and reduced memory B cells.

    • Conclusions:

    • The underlying cause of CVID remains elusive.
    • Further research is needed to understand CVID pathogenesis.
    • Improved diagnostic strategies are crucial for timely patient management.
