Objective To investigate the rate of radiographic progression, as measured with the carpo-metacarpal ratio (Poznanski score), during etanercept (ETN) therapy in children with polyarticular idiopathic arthritis (JIA). Methods Patients included in the Italian ETN registry who had a standard radiograph of both hands and wrists in the posteroanterior view made tit start of treatment and after 1 year were included in the study. The clinical response was assessed by means of the ACR Pediatric definition of improvement. Radiographic progression was determined by calculating the change in the Poznanski score between the baseline and 1-year radiographs. Results A total of 40 patients were studied. The frequency of ACR pediatric 30, 50, and 70 response at 1 year was 77%, 72%, and 50%, respectively. The median Change in the Poznanski score between baseline and 1 Year was + 0.3 units, meaning that, on average, patients experienced improvement in radiographic progression. Conclusion Our pilot study provides evidence that ETN is potentially capable of reducing the progression of radiographic joint damage in JIA. This finding deserves confirmation in a controlled trial.

Abstract

Objective To investigate the rate of radiographic progression, as measured with the carpo-metacarpal ratio (Poznanski score), during etanercept (ETN) therapy in children with polyarticular idiopathic arthritis (JIA). Methods Patients included in the Italian ETN registry who had a standard radiograph of both hands and wrists in the posteroanterior view made tit start of treatment and after 1 year were included in the study. The clinical response was assessed by means of the ACR Pediatric definition of improvement. Radiographic progression was determined by calculating the change in the Poznanski score between the baseline and 1-year radiographs. Results A total of 40 patients were studied. The frequency of ACR pediatric 30, 50, and 70 response at 1 year was 77%, 72%, and 50%, respectively. The median Change in the Poznanski score between baseline and 1 Year was + 0.3 units, meaning that, on average, patients experienced improvement in radiographic progression. Conclusion Our pilot study provides evidence that ETN is potentially capable of reducing the progression of radiographic joint damage in JIA. This finding deserves confirmation in a controlled trial.
