title: Diagnosis of drug-induced liver injury in Japanese patients by criteria of Consensus Meetings in Europe.
abstract: Eighty-five Japanese patients with drug-induced liver injury were assessed by criteria of Consensus Meetings in Europe on causality assessment of drug-induced liver injury. Histopathological investigation was performed for all patients to confirm the diagnosis. We divided these patients into two groups by the date of disease onset. Cases before 1989 were defined as past cases, and those after 1990 as recent cases, because the clinical-pathological characteristics of drug-induced liver injury have changed due to the ability to diagnose hepatitis C virus infection since 1990. Fifty-seven patients with drug-induced liver injury were enrolled as past cases, and 28 as recent cases. For past cases, the results of assessment by the criteria of Consensus Meetings in Europe were as follows: 'very likely': 14 patients (25%), 'likely': 23 patients (40%), 'possible': 15 patients (26%), 'dubious': five patients (9%), and 'unlikely': none (0%). For recent cases, the results were as follows: 'very likely': six patients (22%), 'likely': 14 patients (42%), 'possible': six patients (22%), 'dubious': two patients (7%), and 'unlikely': none (0%). There were no differences between the past and recent cases in distribution of assessment. More than 90% of patients were assessed as 'possible' or more, and the remaining seven patients were assessed as 'dubious'. No patients were assessed as 'unlikely'. Five of seven patients assessed as 'dubious' had long-term cholestasis, and two had alcohol consumption. These results indicated that the criteria of Consensus Meetings in Europe were useful for diagnosing drug-induced liver injury in Japanese patients.
