Clinical manifestations of CNO range widely from moderate, time-limited, monofocal inflammation of the bone to extreme multifocal or chronically active inflammation of the bone.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Objectives<\/jats:title>\n                <jats:p>The main aim of this study was to explore the correlation between musculoskeletal (MSK) symptoms and health-related quality of life (HRQoL) in patients with CNO.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>Children and adults with CNO and their parents were asked to answer a web-based survey. The survey consisted of multiple questions centered around demographic, clinical and therapeutic data, MSK discomfort form based on the Nordic MSK Questionnaire and HRQoL based on Pediatric Quality of Life Inventory-4 (PedsQL-4) and PedsQL rheumatology module. The inclusion criteria included diagnosis of CNO before the age of 18.

The median number of bones affected by CNO was 5 and ranged from 1 to 24 bones. Among the studied patients, 45 patients (66.2%) had MSK manifestations at the last month. The most commonly affected part was ankle and feet (26.5%). Regarding HRQoL, patients with MSK manifestations had lower scores than did patients without in PedsQL-4 (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001) including domains of physical functioning (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001), emotional functioning (<jats:italic>p<\/jats:italic>\u2009=\u20090.033), social functioning (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001) and school functioning (<jats:italic>p<\/jats:italic>\u2009=\u20090.007) in addition to lower scores in PedsQL rheumatology module (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001) including domains of pain and hurt (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001), daily activities (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001), treatment (<jats:italic>p<\/jats:italic>\u2009=\u20090.035), worry (<jats:italic>p<\/jats:italic>\u2009=\u20090.001) and communication (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>MSK manifestations have a negative impact on HRQoL in CNO patients.
