This study found a high frequency (70.8%) of antiphospholipid antibodies in autoimmune hepatitis patients, but no clinical, biological, or histological correlations. Further research is needed to understand this association.

Area of Science:

  • Immunology
  • Hepatology
  • Rheumatology

Context:

  • Autoimmune hepatitis (AIH) is a chronic liver disease with autoimmune origins.
  • The association between AIH and antiphospholipid antibodies (aPLs) is not well-established, with limited previous reports.
  • Antiphospholipid antibodies are associated with an increased risk of thrombosis and pregnancy complications.

Purpose:

  • To determine the frequency of antiphospholipid antibodies in patients with autoimmune hepatitis.
  • To investigate potential correlations between the presence of aPLs and clinical, biological, or histological features of AIH.
  • To compare findings with existing literature on aPLs and AIH.

Summary:

  • A high frequency (70.8%) of antiphospholipid antibodies was detected in 24 AIH patients.

  • Specific antibodies found include IgG anticardiolipin (ACL), IgM anti-beta2 glycoprotein I (Abeta2GP1), and others.
  • No significant correlations were observed between aPLs and hypergammaglobulinemia, clinical presentation, biological markers, or histological findings in AIH.
  • Four patients had antiphospholipid syndrome, and seven had co-existing systemic lupus erythematosus.
  • Impact:

    • This study highlights a frequent co-occurrence of antiphospholipid antibodies in autoimmune hepatitis.
    • The findings suggest that while aPLs are common in AIH, they may not directly influence disease characteristics or outcomes.
    • Further large-scale, longitudinal studies are recommended to elucidate the clinical significance and potential therapeutic implications of this association.
