A case of severe recurrent hepatitis with common variable immunodeficiency.

Area of Science:

• Hepatology
• Immunology
• Pediatrics

Background:

• Severe hepatitis with unclear etiology presents a diagnostic challenge.
• Histological and clinical features initially suggested autoimmune hepatitis.
• The patient exhibited declining immunoglobulin levels and impaired B cell function.

Purpose of the Study:

• To investigate the etiology of severe hepatitis in a young patient.
• To evaluate the efficacy of a combination therapy for hepatitis in the context of immunodeficiency.
• To establish diagnostic and therapeutic guidelines for persistent hepatitis in patients with common variable immunodeficiency (CVID).

Main Methods:

• A 16-year-old boy with severe hepatitis received intravenous glycyrrhizin and oral ursodeoxycholic acid.
• Disease activity was monitored through liver histology and serum alanine aminotransferase levels.
• Immunoglobulin levels and B cell function were assessed to diagnose common variable immunodeficiency (CVID).

Main Results:

• Combination therapy led to normalization of serum alanine aminotransferase levels.
• The patient's liver histology improved significantly after 27 months.
• The diagnosis of common variable immunodeficiency (CVID) was established due to impaired immunoglobulin production.
• The patient tolerated the therapy well, avoiding severe infections and over-immunosuppression.

Conclusions:

• Persistent hepatitis in patients with common variable immunodeficiency (CVID) can be effectively managed with a combination of glycyrrhizin and ursodeoxycholic acid.
• This therapeutic approach improves liver histology and biochemical markers while preventing severe infections.
• Further research is needed to establish definitive diagnostic criteria and therapeutic strategies for hepatitis associated with CVID.
