Abstract:
Objective:To analyze the clinical data of children with rheumatic diseases complicated with osteonecrosis and summarize the clinical characteristics, so as to guide clinical work.
Methods:The clinical data of 59 children with rheumatic diseases complicated with osteonecrosis from January 2010 to July 2018 were collected and analyzed retrospectively.
Results:Among 59 children with rheumatic diseases complicated with bone infarction, 25 cases were systemic lupus erythematosus (SLE), 4 cases were mixed connective tissue disease, 6 cases were juvenile dermatomyositis, 1 case was Takayasu arteritis, 1 case was leukocy to clystic vasculitis, 13 cases were systemic onset juvenile idiopathic arthritis (SJIA), 1 case was polyarthritis, and 8 cases were juvenile ankylosing spondylitis. The median time from the onset of rheumatic diseases to osteonecrosis onset was 18 (7.00, 38.75) months. A total of 115 joints were involved in 59 children, the most common of which were bilateral hips and knees. Twenty-five were single joint involvement and 34 were multiple joints involvement. There were 37 cases (63%) with vasculitis, 9 cases (15%) with oralulcer, 5 cases (8%) with Raynaud's phenomenon, 31 cases (53%) with Cushing's face, 18 cases (31%) with kidney involvement, 25 cases (42%) with hypertension, and 12 cases (24%) with spinal compression frac- tures. According to statistics, 10 children with osteonecrosis occurred without glucocorticoid intake. The longest duration of glucocorticoid therapy was 13 years, and the average duration was about (27±35) months whensymptomatic osteonecrosis occurred. The median cumulative dose of prednisone was 381.9(209.77, 561.19) mg/kg.
Conclusion:SLE, SJIA and juvenile ankylosing spondylitis are the three most common rheumatic diseases in children with osteonecrosis. The locations of osteonecrosis are mostly the bilateral hips and knees. It is necessary to strengthen joint examination, physical examination and imaging screening for children with rheumatic diseases after 18 months of onset, so early detection, early treatment are the strategy to improve the prognosis of the diseases.
