Chronic active liver disease with common variable hypogammaglobulinemia

G O Solley, E R Dickson, G J Gleich

    Mayo Clinic Proceedings
    |February 1, 1979

    Summary

    This study presents a case of chronic active liver disease in a patient with hypogammaglobulinemia, suggesting liver injury is independent of immunoglobulin levels. Immunosuppressive therapy proved effective and well-tolerated in this unique case.

    Area of Science:

    • Immunology
    • Hepatology
    • Gastroenterology

    Background:

    • Chronic active liver disease (CALD) often presents with elevated serum immunoglobulins, but their pathogenic role remains unclear.
    • Hypogammaglobulinemia, a condition characterized by low immunoglobulin levels, typically predisposes individuals to recurrent infections.
    • This report details a rare case of CALD developing in a patient with long-standing hypogammaglobulinemia.

    Observation:

    • A 41-year-old male with a history of recurrent respiratory infections and diarrhea since 1954 presented with absent serum IgA and IgM, and low IgG levels.
    • Liver enzyme abnormalities were noted in 1974, leading to a diagnosis of chronic active liver disease with cirrhosis and active hepatitis confirmed by biopsy.
    • Lymphocyte studies indicated that T cells inhibited B-cell maturation and immunoglobulin production.

    Findings:

    • The patient's chronic active liver disease developed despite hypogammaglobulinemia, challenging the conventional association between elevated immunoglobulins and CALD.
    • Treatment with azathioprine and prednisone led to improvements in liver enzymes and a reduction in infection frequency.
    • This case demonstrates that liver cell injury in CALD may occur independently of immunoglobulin levels.

    Implications:

    • The findings suggest that elevated immunoglobulins are not essential for the pathogenesis of liver cell injury in all cases of chronic active liver disease.
    • Immunosuppressive therapy, including azathioprine and prednisone, can be safely administered to patients with hypogammaglobulinemia and chronic active liver disease.
    • This case expands our understanding of the complex interplay between the immune system and liver disease, particularly in immunocompromised individuals.
