Predicting liver injury in autoimmune hepatitis using a specific antibody test

Prospective Multicenter Study: PredIcting SterOid DepeNdEnt LivEr Injury (PIONEER) with Polyreactive Immunoglobulin G

Observational Hannover Medical School · NCT05810480

This study is testing if a specific antibody test can help doctors better diagnose autoimmune hepatitis in both adults and children, especially when other tests don't show clear results.

What this trial studies

This observational study aims to evaluate the diagnostic capacity of polyreactive immunoglobulin G (pIgG) in predicting autoimmune hepatitis (AIH) compared to other liver diseases. The study will utilize a homemade ELISA to quantify pIgG levels in patients undergoing diagnostic liver biopsies. By assessing the presence of pIgG, the researchers hope to improve diagnostic accuracy for AIH, particularly in cases where conventional autoantibodies are negative. The study will include adults and children diagnosed with various liver diseases to establish the effectiveness of pIgG as a diagnostic tool.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals undergoing diagnostic liver biopsies for suspected liver diseases.

Not a fit: Patients with ongoing immunosuppression or those undergoing biopsies for already known liver diseases may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more accurate diagnoses of autoimmune hepatitis, allowing for timely and appropriate treatment.

How similar studies have performed: Other studies have shown promise in using specific antibody tests for diagnosing autoimmune conditions, suggesting potential success for this novel approach.
