BACKGROUND AND AIM: There is no gold standard for making the diagnosis of autoimmune hepatitis (AIH), and the diagnosis of acute onset AIH (A-AIH) is most challenging. A-AIH sometimes develops into acute liver failure with poor prognosis if the diagnosis is delayed. Therefore, it is most important for the better prognosis to diagnose non-severe A-AIH early and treat appropriately. However, features in the early stage of A-AIH are unclear. We examined initial characteristics of non-severe A-AIH in detail and tried to find novel clinical features for the early diagnosis.
METHODS: Clinical, biochemical, immunological, radiological, and histological features of 71 patients (54 women, mean age 57.9 ± 14.3 years) with non-severe A-AIH admitted to community hospitals between 2001 and 2022 were analyzed retrospectively.
RESULT: Forty-six had no symptom on onset and liver injuries were discovered by regular medical checkups. The mean duration from onset to consultation was 25.0 ± 29.3 days. Liver histology showed acute hepatitis in 59% and chronic hepatitis in 41%. Patients with symptoms revealed more male sex (P = 0.039), higher alanine aminotransferase (P < 0.001), higher total bilirubin (P < 0.001), and higher rate of histological acute hepatitis (P = 0.0013) than those without symptoms significantly. Male sex, presence of symptoms on onset, occurrence of jaundice in the course, and histological acute hepatitis were correlated.
CONCLUSIONS: Sixty-five percent of non-severe A-AIH patients were asymptomatic on onset, suggesting that A-AIH would develop insidiously and present a longer clinical course than that reported. Male patients more often revealed true acute hepatitis clinically, biochemically, and histologically than female ones.
