Simplified Scoring for AIH
Formula :
Composite score of listed variables. Points given for each variable.
Explanation of Result :
> 6 is consistent with definite diagnosis. 6 is consistent with probable diagnosis.
* Please verify all calculations prior to clinical use.

Abstract
Diagnostic criteria for autoimmune hepatitis (AIH) have been created and revised by the International Autoimmune Hepatitis Group (IAIHG). Simplified criteria have been created, but remain independently unvalidated. We report on the diagnostic accuracy of the simplified criteria in patients across a range of diagnoses, including a subset of patients presenting with fulminant liver failure who required liver transplant. Patients with AIH and non-AIH etiologies of liver disease were identified from dedicated patient databases. Parameters relevant to the simplified and 1999 IAIHG criteria were recorded, and sensitivity, specificity, and positive and negative predictive values for scores of >or=6 (probable AI [...]

Abstract
BACKGROUND:
The diagnosis of autoimmune hepatitis (AIH) is already difficult, and that of acute-onset AIH with atypical features is even more challenging, even though the revised original diagnostic criteria created by an international AIH group were widely accepted and incorporated into clinical practice.
AIMS:
Recently, simplified diagnostic criteria were proposed. We compared the performance parameters of the simplified scoring system in patients with acute-onset AIH and examined its usefulness and limitations.
METHODS:
Fifty-five patients with acute-onset AIH (29 non-severe, 14 severe and 12 fulminant) were assessed according to the simplified scoring system and co [...]

Abstract
BACKGROUND & AIMS:
Criteria for the diagnosis of autoimmune hepatitis (AIH) were formalized in 1993 and revised in 1999. Simplified criteria were developed in 2008 for adults only. We aimed to establish clinically useful diagnostic criteria for AIH in children by validating the 2008 criteria in a pediatric cohort.
METHODS:
Baseline data were available in 37 and 31 AIH and 40 and 26 non-AIH subjects to calculate 1999 and 2008 criteria, respectively. Sensitivity and specificity of the simplified criteria were calculated using 1999 criteria as the standard for subjects with available data for both criteria.
RESULTS:
The 1999 standard designated 29 of 31 subjects (94%) [...]
