Effect of body composition on bone mineral density in Moroccan patients with juvenile idiopathic arthritis.

Introduction: The link between bone mass and body composition is widely recognized, but only few works were selectively performed on subjects with juvenile idiopathic arthritis. The aim of our study was to investigate the effect of body composition on bone mineral density (BMD) in Moroccan patients with juvenile idiopathic arthritis.

Methods: Thirty three children with juvenile idiopathic arthritis (JIA) were included in a cross-sectional study.

Vitamin D concentrations and disease activity in Moroccan children with juvenile idiopathic arthritis.

Background: In addition to its important metabolic activities, vitamin D also contributes to the regulation of the immune system. The aim of this study was to assess the relationship between hypovitaminosis D and disease activity in Moroccan children with juvenile idiopathic arthritis (JIA).

Methods: In this cross-sectional study, forty children with JIA were included, all having been diagnosed according to the classification criteria of International League of Associations for Rheumatology (ILAR).
