This prospective, long-term observational study, initiated in 2002, aimed to characterize clinical and laboratory data, whole body MRI detected lesions, and treatment responses in 37 juvenile patients with chronic non-bacterial osteomyelitis at a time when biological DMARDs were not yet standard therapy.
Patients were assessed at baseline and at 1 (without MRI), 3, 6, 12, 18, 24, 36, 48, 60 months. All patients received naproxen as first-line therapy. Clinical management allowed for escalation to sulfasalazine, pamidronate, and glucocorticoids as needed. Treatment response was evaluated using the pedCNO disease activity score (30/50/70/90% improvement). Further composite numeric disease activity (DA) scores- the CARRA CDAS and a new MRI DAS - were applied.
The mean age at disease onset was 10.8 years, with a diagnostic delay of 5.8 months. Naproxen was the initial treatment in all patients. Second-line therapy was initiated in 10 patients due to inadequate improvement in physician global assessment of disease activity, patient-reported overall wellbeing or MRI lesions. Escalated therapies included sulfasalazine (n = 10), bisphosphonates (n = 1), methotrexate (n = 1), and short- (< 4 wks) or long-term oral glucocorticoids (n = 5 and n = 3, respectively). The mean number of clinical lesions decreased from 2.1 to 0.4 at 12 months and reached 0.15 at 60 months. MRI-detected lesions declined from 5.0 to 2.25 at 12 months and to 1.1 at 60 months.
Most children experienced favourable long-term outcomes. Clinical improvement occurred more rapidly than radiologic resolution. Patients with insufficient response to NSAIDs should be considered for a treat-to-target approach, including the use of conventional and biologic DMARDs.
A trial registration EUDRA CT was not available at the time the study was started. Informed consent was given by all parents.
这项前瞻性长期观察性研究始于2002年,旨在描述37例慢性非细菌性骨髓炎青少年患者的临床和实验室数据、全身MRI检测到的病变以及治疗反应,当时生物性改善病情抗风湿药(bDMARDs)尚未成为标准治疗方法。
在基线以及第1个月(无MRI检查)、3个月、6个月、12个月、18个月、24个月、36个月、48个月、60个月时对患者进行评估。所有患者均接受萘普生作为一线治疗。临床管理允许根据需要升级为柳氮磺胺吡啶、帕米膦酸盐和糖皮质激素。使用儿童慢性非细菌性骨髓炎疾病活动评分(改善30%/50%/70%/90%)评估治疗反应。还应用了进一步的综合数字疾病活动(DA)评分——儿童风湿病研究联盟(CARRA)综合疾病活动评分(CDAS)和一种新的MRI疾病活动评分。
疾病发病的平均年龄为10.8岁,诊断延迟5.8个月。萘普生是所有患者的初始治疗药物。由于医生对疾病活动的整体评估、患者报告的总体健康状况或MRI病变改善不足,10例患者开始二线治疗。升级后的治疗包括柳氮磺胺吡啶(n = 10)、双膦酸盐(n = 1)、甲氨蝶呤(n = 1)以及短期(<4周)或长期口服糖皮质激素(分别为n = 5和n = 3)。临床病变的平均数量在12个月时从2.1降至0.4,在60个月时降至0.15。MRI检测到的病变在12个月时从5.0降至2.25,在60个月时降至1.1。
大多数儿童获得了良好的长期预后。临床改善比影像学分辨率出现得更快。对非甾体抗炎药反应不足的患者应考虑采用达标治疗方法,包括使用传统和生物性改善病情抗风湿药。
