Record number: 
Adverse Occurrence type: 
MPHO Type: 
Estimated frequency: 
Up to 70% of liver transplant (LT) recipients
Time to detection: 
12 - 36 months
Alerting signals, symptoms, evidence of occurrence: 
92 consecutive LT recipients for whom prospectively stored frozen sera were available for autoantibodies assessment by immunofluorescence were evaluated. Antinuclear (ANA), antismooth muscle (ASMA), and anti liver–kidney microsomal type 1 (anti-LKM) in up to 70% of the liver transplant recipients.
Demonstration of imputability or root cause: 
Patients had previously tested negative became autoantibody positive after grafting. Patients with graft dysfunction had a significantly higher autoantibody prevalence irrespective of the etiology of liver injury as compared to those patients with persistently normal liver biochemistry.
Imputability grade: 
2 Probable
