BackgroundChronic non-bacterial osteomyelitis is a chronic sterile inflammatory bone condition. We aimed to describe patients' clinical and radiographic findings and to evaluate their response to therapy and their quality of life. MethodsThis cross-sectional study included 18 patients from a single center in Turkey whose clinical, radiological features, and outcomes were reviewed retrospectively. The quality of the patients' lives after treatment was compared with healthy controls using the Pediatric Quality of Life Inventory 4.0. ResultsThe median age of disease onset was 12 years (IQR 10-14 years) and 11 (61.1%) patients were male. The median follow-up duration was 15 months (IQR 12-22 months). The persistent form of chronic non-bacterial osteomyelitis was the most common pattern in 15 (83.3%) patients and a recurrent pattern was defined in three (16.7%) patients. The lesions were multifocal in all patients and 15 (83.3%) patients had symmetric distribution in whole-body magnetic resonance imaging. The most common sites of arthritis were the knee and sacroiliac joints. Methotrexate was used in 16 (88.9%) patients as first-line therapy. However, some patients were unresponsive to the first-line therapy and needed tumor necrosis factor-alpha inhibitors (55.6%) and bisphosphonates (16.7%). We observed remission in only four (22.2%) patients, and three (16.7%) patients were unresponsive. The patients had a significantly poorer quality of life than controls (P = 0.005). ConclusionsChronic non-bacterial osteomyelitis is an insidious disease that requires detailed analysis for diagnosis and whole-body magnetic resonance imaging is an effective tool for its diagnosis. Despite the advanced treatment, patients with chronic non-bacterial osteomyelitis have a poor quality of life.
