Summary
Common variable immunodeficiency (CVI) causes low immunoglobulin levels, leading to recurrent infections and increased risks of autoimmune diseases, gastrointestinal issues, and certain cancers. Its underlying causes remain poorly understood despite its frequency.
Area of Science:
- Immunology
- Clinical Medicine
Context:
- Common variable immunodeficiency (CVI) is a primary immunodeficiency disorder.
- Characterized by impaired antibody production and low serum immunoglobulin levels.
- Leads to recurrent bacterial infections, particularly respiratory tract infections.
Purpose:
- To provide an overview of Common Variable Immunodeficiency (CVI).
- To report on the authors' experience with 18 CVI cases over five years.
- To highlight the clinical manifestations, associated conditions, and diagnostic challenges of CVI.
Summary:
- CVI presents with defective antibody formation, resulting in hypogammaglobulinemia.
- Clinical features include recurrent sinopulmonary infections, Giardia infections, and gastrointestinal disorders.
- Associated conditions encompass autoimmune diseases (20%), non-Hodgkin lymphoma, and gastric carcinoma.
- The pathogenesis of CVI is not well-defined, despite its prevalence.
Impact:
- Enhances understanding of CVI's heterogeneous clinical presentation.
- Contributes to the limited data on CVI pathogenesis.
- Informs clinical management and diagnosis of patients with CVI.
- Highlights the need for further research into CVI etiology and treatment.
