Abstract

Chronic recurrent multifocal osteomyelitis (CRMO) is a chronic autoinflammatory disease that primarily affects the skeleton in the absence of an infectious etiology in children and adolescents. We report demographic, clinical and laboratory characteristics of a single center cohort of CRMO patients (33) in Morozov Children’s City Clinical Hospital between 2011 and 2021. 25 (75%) were female. Median age of symptoms onset was 9 [7;13] years. Median delay in diagnosis was 12 months. All patients had bone pain as an initial symptom; fever has been present in 12 patients (63%). Joints involvement was observed in 22 patients (67%). All of the patients had multifocal bone lesions. Eleven patients (33%) also had sacroiliitis. Other organs involvement was observed 7 patients presented with palmoplantar pustulosis and psoriasis. Histopathological diagnosis was confirmed in 24 (73%) patients. Mean erythrocyte sedimentation rate (ECR) was 43 mm/h and C-reactive protein (CRP) - 27 mg/L. 23 (69,6%) patients had immunological activity. CRMO remains a rare diagnosis. From our experience, most of the patients had delay in diagnosis.
