Pubertal disorders in juvenile idiopathic arthritis: a systemic review.

Introduction: Juvenile idiopathic arthritis (JIA) is a chronic inflammatory disease beginning before 16 years. Inflammatory cytokine, medication, and genetic factors may lead to puberty disorders in children with JIA. The main objectives of this systematic review were to elucidate the impact of JIA on puberty and identify the influential factors that disrupt puberty.

Content: A systematic literature review was performed on pubertal disorders from Medline, Google Scholar, and Scopus databases. This systematic review followed the preferred reporting items for systematic review guidelines. The initial search yielded 4,011 articles: identified by Google Scholar (3,880), PubMed (99), and Scopus (940). Finally, 11 articles were retained.

Summary and outlook: The age of menarche onset, Tanner stage, and pubertal signs were later compared with controls. The mean age of menarche onset ranged from 12.0 ± 0.3 to 13.39 ± 0.93 years for the JIA girls. This delay was more reported in the polyarticular and oligoarticular subtypes. Menstrual irregularities, metrorrhagia with irregular cycles, primary oligomenorrhea, and secondary amenorrhea were also reported. Factors found to influence delayed menarche and puberty were steroid use, JIA subtype, disease duration, and age at onset. Any studies have focused on the effect of puberty on JIA outcomes. Overall, our review revealed that pubertal disorders are frequent in JIA patients with polyarticular and systemic subtypes. However, some influencing factors remain editable if well-assessed and controlled.
