    Abstract:
    BACKGROUND: Forty percent of patients with autoimmune hepatitis (AIH) present with acute jaundice/hepatitis. Such patients, when treated promptly, are thought to have a good prognosis. OBJECTIVES: The objective of this study was to describe the natural history of AIH in patients presenting with jaundice/hepatitis and to determine whether the diagnosis could have been made earlier, before presentation. METHODS: This study is a retrospective review of 2249 consecutive patients who presented with jaundice to the Jaundice Hotline clinic, Truro, Cornwall, UK, over 15 years (1998-2013) and includes a review of the laboratory data over a 23-year period (1990-2013). RESULTS: Of the 955 patients with hepatocellular jaundice, 47 (5%) had criterion-referenced AIH: 35 female and 12 male, the median age was 65 years (range 15-91 years); the bilirubin concentration was 139 μmol/l (range 23-634 μmol/l) and the alanine transaminase level was 687 IU/l (range 22-2519 IU/l). Among the patients, 23/46 (50%) were cirrhotic on biopsy; 11/47 (23%) died: median time from diagnosis to death, 5 months (range 1-59); median age, 72 years (range 59-91 years). All 8/11 patients who died of liver-related causes were cirrhotic. Weight loss (P=0.04) and presence of cirrhosis (P=0.004) and varices (P=0.015) were more common among those who died. Among patients who died from liver-related causes, 6/8 (75%) died less than 6 months from diagnosis. Cirrhosis at presentation and oesophageal varices were associated with early liver-related deaths (P=0.011, 0.002 respectively). Liver function test results were available in 33/47 (70%) patients before presentation. Among these patients, 16 (49%) had abnormal alanine transaminase levels previously, and eight (50%) were cirrhotic at presentation. CONCLUSION: AIH presenting as jaundice/hepatitis was mainly observed in older women: 50% of the patients were cirrhotic, and liver-related mortality was high. Some of these deaths were potentially preventable by earlier diagnosis, as the patients had abnormal liver function test results previously, which had not been investigated.
