Common variable immunodeficiency (CVID) is the commonest primary immunodeficiency disease characterized by defective antibody production and various degrees of T cell numbers abnormality or impaired proliferation to mitogens. Clinical features include recurrent bacterial sinopulmonary and gastrointestinal infections. Autoimmunity is very common in CVID, occurring in approximately 25% of the patients particularly with autoimmune thrombocytopenia, hemolytic anemia, inflammatory bowel disease, and rheumatoid arthritis. Persistent antigen stimulation, secondary to a defective eradication of pathogens followed by a compensatory exaggerated chronic inflammatory response, is the primary cause leading to autoimmunity. Here we describe a girl with CVID in whom a chronic liver disease mimicking autoimmune hepatitis developed after hepatitis C virus infection. The immunosuppressive treatment with cyclosporine A proved effective in reversing liver disease.
