Abstract

Objective Chronic nonbacterial osteomyelitis (CNO), an inflammatory bone disease, results from immune cell cytokine overproduction. Patients may complain of bone and joint pain, myalgia, and mucocutaneous lesions, impacting all bones. We aim to share clinical insights on CNO diagnosis, management, and monitoring. Method We retrospectively analyzed the demographic and clinical data of 9 children diagnosed with CNO at our pediatric rheumatology clinic. Patients aged 0-18 years who were followed for at least 6 months were included. Results Out of the 9 CNO patients, 3 (33.3%) were female and 6 (66.7%) were male. The median age at diagnosis was 11 years (range: 6.5-16 years), and the diagnosis delay averaged 14.3 months (range: 2-36 months). Fatigue and bone pain were the most common symptoms. In physical examination, localized tenderness was found in 7 (77.7%) patients, arthritis in 6 (66.6%), and bone deformity in 1 (11%). Magnetic resonance imaging revealed multiple bone lesions in 8 (88.8%) patients, primarily in the lower extremities. Non-steroidal anti-inflammatory treatment was initiated for all patients. Methotrexate was introduced in 7 (77.7%) patients during follow-up, and one patient received a biological agent due to multifocal lesions. Three patients transitioned from methotrexate to a biological agent due to inadequate clinical and laboratory improvement. Additionally, bisphosphonate was combined with methotrexate for one patient due to vertebral height reduction. Clinical remission was achieved in 8 patient. Conclusion As a result, the data we uncovered in our study regarding the clinical characteristics, radiological findings, treatment options, and responses to anti-inflammatory treatments in children diagnosed with CNO may raise awareness, especially among pediatricians. We predict that, with heightened physician awareness, the delay in diagnosis will decrease, and treatment success will increase.

Özet

Giriş Kronik non-bakteriyel osteomiyelit (KNO), bağışıklık hücreleri tarafından sitokinlerin aşırı ekspresyonunun neden olduğu inflamatuar bir hastalıktır. Hastalar kemik ağrısı, eklem ağrısı, miyalji, mukokutonöz lezyonlar ile hastaneye başvurabilmektedir. Hastalık tüm kemikleri tutabilme özelliğine sahiptir. Bu çalışmanın amacı KNO tanı, tedavi ve takip süreci ile ilgili klinik deneyimlerimizi paylaşmaktır. Yöntem Pediatrik romatoloji polikliniğinde KNO tanısı alan 9 çocuğun demografik verileri ve klinik özellikleri geriye dönük olarak incelendi. En az 6 ay takip edilen 0-18 yaş arası hastalar dahil edildi. Bulgular Çalışmaya dahil edilen 9 KNO hastasının 3’ü (%33,3) kız, 6’sı (%66,7) erkekti. Ortanca tanı yaşları 11 (6,5-16) yıl ve tanı gecikme süresi 14,3 (2-36) aydı. En sık başvuru bulgusu halsizlik ve kemik ağrısıydı. Fizik muayenede; 7 (%77,7) hastada lokalize hassasiyet, 6’ında (%66,6) artrit ve birinde (%11) kemik deformitesi saptandı. Manyetik rezonans görüntülemede, 8 (%88,8) hastada birden çok kemik lezyonu vardı. Hastaların 8’inde (%88,8) alt ekstremite tutulumu vardı ve klavikula tutulumu dışında hastaların hiçbirinde üst ekstremite tutulumu yoktu. Tüm hastalara steroid dışı anti-inflamatuar tedavi başlandı. İzlemde 7 (%77,7) hastaya metotreksat başlandı. Bir hastanın tedavisine çok odaklı tutulumu olduğundan biyolojik ajan eklendi. Metotreksat başlanan 7 hastadan 3’ünde (%33,3) yeterli klinik ve laboratuvar düzelme olmadığı için biyolojik ajana geçildi. Ayrıca 1 (%11) hastada vertebrada yükseklik kaybı olduğu için metotreksat tedavisine bifosfonat eklendi. Sekiz hasta klinik remisyona ulaştı. Sonuç Sonuç olarak çalışmamızda KNO tanısı alan çocukların klinik özellikleri, radyolojik bulguları, tedavi seçenekleri, anti-inflamatuar tedavilere yanıtları ile ilgili saptadığımız veriler özellikle çocuk hekimleri için farkındalık yaratabilir. Farkındalığı olan hekimler sayesinde tanı gecikmesinin azaltacağını, tedavi başarısının artıracağını öngörmekteyiz.
