Autoimmune hepatitis in the elderly.
OBJECTIVE
Autoimmune hepatitis (AIH) is widely believed to be a disease of young women and menopause. Little is known about the frequency and clinical characteristics in patients aged > or =65 yr.


METHODS
We reviewed charts of 120 consecutive outpatients with known AIH to identify patients who were diagnosed at the age of 65 or older. These 20 patients (median age, 69 yr) were compared to the same number of younger patients (median age, 24 yr) with well-documented AIH from the same cohort.


RESULTS
Seventeen percent (20/120) of our patients were > or =65 yr at the time of diagnosis. In the older patients median time to diagnosis was significantly longer than in the younger patients (8.5 vs 3.5 months). Patients most commonly presented with an acute icteric hepatitis. Complete remission was achieved to a similar extent (18/20 and 17/20 patients). Fewer older patients expressed human leukocyte antigen A1-B8 (p = 0.005).


CONCLUSIONS
Diagnosis of AIH often seems to be delayed in the elderly, presumably because AIH is erroneously considered to be a disease of young age. Presentation with acute icteric hepatitis is similar to that of younger patients, supporting the assumption that beneficial effects of hormonal changes associated with menopause are not as pronounced in AIH as in other autoimmune diseases. Human leukocyte antigen type seems to have an influence on the age of onset of AIH. Prognosis is excellent, and AIH should be considered in the older patient to avoid delayed initiation of immunosuppressive therapy.
