Pharmacovigilance in juvenile idiopathic arthritis patients (Pharmachild) treated with biologic agents and/or methotrexate. Consolidated baseline characteristics from Pharmachild and other national registries
Pediatric Rheumatology volume 12, Article number: P7 (2014)
The availability of methotrexate (MTX) and biological agents has provided a major change in the treatment of children with juvenile idiopathic arthritis (JIA). An international registry named Pharmachild (European Union grant 260353) has been set up by the Pediatric Rheumatology International Trials Organisation (PRINTO)/Pediatric Rheumatology European Society (PRES). In parallel several national registries with the same purpose have been set up in different European Countries for the follow-up of these patients.
To evaluate the possibility to combine data coming from different national registries in order to assess the long-term safety.
We merged into a unified database the baseline demographic data of JIA patients treated with MTX or biologicals coming from the Pharmachild registry and from the national registries of Germany, United Kindgom and Portugal. Data are presented as frequencies (%) or medians with 1st and 3rd quartiles.
About 63% of the patients has been treated with biologicals alone or in combination with MTX, and 29% only with MTX. The events of special interest (ESI) ranged from 4.5 to 15.0% and the other moderate/severe/serious adverse events (AE) from 13.1% to 69.9%. Table 1.
Combination of information from different data sources is a recommended task and will provide a powerful tool for the future analysis of safety events coming from different registries.
