Objectives: Intraarticular corticosteroid injections are an important part of the treatment for juvenile idiopathic arthritis due to the ability to achieve high concentration of the medication in the affected joint, while minimizing potential systemic adverse effects. There may be some systemic absorption of corticosteroids resulting in systemic adverse events. Our aim was to demonstrate the potential of adverse events due to the systemic absorption of intraarticular corticosteroids through presentation of 2 case reports, a review of our practices and a systematic review of the literature.
Methods: We reviewed the intraarticular injections performed at our 3 centers in 2010 and 2011 for the prevalence of systemic adverse events. We searched PubMed for articles in English on systemic adverse effects of intraarticular corticosteroid injection in children, using numerous keywords, as well as review articles and textbooks on juvenile rheumatoid/idiopathic arthritis up to and including December 2011.
Results: We report the development of severe acneiform rashes in 2 adolescents with juvenile idiopathic arthritis following bilateral knee intraarticular injections of triamcinolone hexacetonide. The prevalence of systemic adverse events at our centers was in 4/179 (2.2%) injections, the 2 cases reported above, 1 case of insomnia in a 2-year-old child and 1 case of cushingoid features following injection of 21 joints. While in the literature there are some reports of general "Cushing-like" appearances, there are only very few reports of specific skin and other organ/system adverse effects resulting from systemic corticosteroid absorption.
Conclusion: It is important to recognize the potential of rare adverse events that are attributable to the systemic absorption of intraarticular corticosteroids in children.
