Composite Model to Predict Curve Severity of Adolescent Idiopathic Scoliosis: A 6-Year Longitudinal Study beyond Skeletal Maturity
Refereed conference paper presented and published in conference proceedings


摘要Introduction: The aetiopathogenesis of adolescent idiopathic scoliosis (AIS) remains unclear. Early risk evaluation of curve severity for timely intervention is important. We previously reported miR-145-5p in AIS osteoblasts impairing osteocytogenic differentiation and we have discussed the clinical implication of serological markers in a small sample size cohort. In the present study, we aimed to evaluate the prognostic value of a composite model in predicting curve severity.
Methods: This was a 6-year longitudinal cohort study. Girls with AIS (n=100) were recruited at their first visit to our clinic. We took blood samples and measured anthropometry and curve severity. The patients with AIS were followed up clinically every 6 months for 6 years. Severe AIS was defined as Cobb’s angle >40°. Serum CTX/P1NP and plasma miRNA level were determined.
Results: Thirty patients had severe AIS at the end of the 6-year study. Patients with severe AIS had significantly higher serum levels of P1NP and significantly lower plasma levels of miR-145 compared with patients with AIS with Cobb’s angle <40°. Plasma miR-145 levels showed negative correlation with Cobb’s angle (p=0.002). Using clinical anthropometric parameters, serum P1NP, and plasma miR-145, our composite model showed outstanding power to predict curve severity with R2 0.575 and hazard ratio of 14.506.
Conclusion: The composite model constructed in this study can guide decision making and disease management at an early stage of AIS to help prevent progression of spinal deformity.
