Summary
Autoimmune hepatitis (AIH), typically seen in young women, can also affect older men. This case highlights AIH diagnosis and effective corticosteroid treatment in elderly males with acute cholostatic hepatitis.
Area of Science:
- Hepatology
- Immunology
- Internal Medicine
Background:
- Autoimmune hepatitis (AIH) is an immune-mediated liver disease.
- AIH predominantly affects young women but can occur in other demographics.
- Acute cholostatic hepatitis presents with obstructive jaundice symptoms.
Observation:
- A case of type I AIH in a 70-year-old male presenting with acute cholostatic hepatitis.
- Diagnosis was confirmed by immunological markers (antinuclear antibodies - ANA) and liver histology.
- Other potential causes of hepatitis were excluded.
Findings:
- Type I AIH can manifest in older male patients.
- High levels of antinuclear antibodies (ANA) are indicative of AIH.
- Liver biopsy confirmed the autoimmune inflammatory process.
Implications:
- AIH should be considered in the differential diagnosis of hepatitis in elderly men.
- Corticosteroid therapy is effective for AIH in older populations.
- This case expands the known demographic profile of AIH presentation.
