This study details three females experiencing recurrent LKM positive hepatitis since childhood. Episodes often resolved spontaneously, with potential links to female hormones and drug triggers discussed.

Area of Science:

  • Hepatology
  • Immunology
  • Endocrinology

Background:

  • Autoimmune hepatitis is a chronic liver disease characterized by immune system attack on liver cells.
  • Liver-kidney microsomal (LKM) antibody positive hepatitis is a specific subtype, often associated with autoimmune processes.
  • Understanding the factors influencing disease relapses is crucial for patient management.

Observation:

  • Three female patients presented with relapsing episodes of LKM positive hepatitis, starting in childhood and continuing through puberty.
  • Hepatitis episodes varied between acute and chronic presentations.
  • Many episodes showed spontaneous resolution with normalization of liver function tests.

Findings:

  • While spontaneous recovery occurred, some patients received treatments including steroids and azathioprine.

  • No definitive precipitating factors were identified.
  • Potential links between disease flares and hormonal events like menarche, oral contraceptive use, and pregnancy were noted.
  • The role of drugs as potential trigger factors for LKM positive hepatitis was considered.

    • Implications:

    • The findings suggest a complex interplay of host factors, possibly including hormonal influences, in the pathogenesis of LKM positive hepatitis.
    • Further research into the mechanisms of LKM positive hepatitis, particularly the role of sex hormones and environmental triggers like drugs, is warranted.
    • This case series highlights the relapsing-natural course of LKM positive hepatitis in females and the need for continued investigation into its etiology.
