Características clínicas y pronóstico de la atresia de vías biliares con niveles bajos de metaloproteinasa 7 de la matriz sérica
Topic overview
Retrospective cohort study examining biliary atresia patients with low serum MMP-7 levels (≤25 ng/ml). Low MMP-7 group showed significantly lower jaundice clearance rates at 3 and 6 months post-Kasai procedure and reduced 1-year native liver survival compared to high MMP-7 patients, suggesting MMP-7 levels may predict surgical outcomes.
Key takeaways
- Serum MMP-7 ≤25 ng/ml in biliary atresia patients correlates with lower preoperative GGT and direct bilirubin levels.
- Low MMP-7 BA patients show significantly worse jaundice clearance at 3 and 6 months post-Kasai (29.7% vs 53.1%, p=0.049).
- One-year native liver survival is markedly reduced in low MMP-7 group (29.6% vs 53.0%, p=0.022).
- Low serum MMP-7 may represent a distinct clinical BA subtype requiring alternative treatment strategies.
- Despite similar preoperative clinical features, MMP-7 level predicts post-Kasai prognosis independent of other markers.
