Intra-articular glucocorticosteroid injection into sternocostoclavicular joints in patients with SAPHO syndrome
Abstract
Painful swelling of the anterior chest wall caused by osteitis and hyperostosis in the sternocostoclavicular region are characteristically observed in patients suffering from SAPHO syndrome. Autoimmune triggering of inflammation and bacterial infection is hypothesized to be involved in the pathogenesis. Promising treatment modalities include antirheumatic and antibiotic medications. Ten patients with SAPHO syndrome and symptomatic osteitis in the sternocostoclavicular region were treated by a single instillation of glucocorticosteroids (20 mg triamcinolone) into the sternocostoclavicular joints. The disease activity was evaluated on the basis of a questionnaire asking for osteitis activity (quantified for complains on a scale of 0-6), by Health Assessment Questionnaire (HAQ) score, erythrocyte sedimentation rate, C-reactive protein, and magnet resonance imaging (MRI) scanning of the sternocostoclavicular region (osteitis scores quantified for inflammation on a scale of 0-2 by the radiologist) prior to injection and after 12 weeks. No changes of the preexisting antirheumatic therapy were allowed during the observation interval. All patients continued the study during the follow-up. The osteitis score changed from 4.2 (mean; stan...Continue Reading

Autoimmune Diseases
Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.
