DESCRIPTION: Juvenile Primary Fibromyalgia Syndrome (JPFS) is a chronic pain condition of unknown etiology and is associated with a great deal of pain, suffering and disability. There are currently no randomized clinical trials for the treatment of pediatric patients suffering from fibromyalgia. The current application is a randomized, placebo controlled clinical trial testing the efficacy of combined behavioral and pharmacological treatment in the treatment of JPFS. Treatments combining pharmacological interventions with behavior change have been found to be efficacious in the treatment of adults with chronic pain but have been understudied in pediatric populations. In this study, we will test whether a combination of pain coping skills training (CST) and low-dose amitriptyline (AMI) is efficacious in reducing functional disability, pain and depressive symptoms in adolescents with JPFS. We will test the hypothesis that coping skills training combined with low-dose amitriptyline (CST+AMI) will be superior to coping skills training + placebo (CST+placebo) or low-dose amitriptyline + attention (AMI+ATT). Further, we will test whether subjects who receive CST+AMI will have significantly less pain, disability and depressive symptoms after a six-month maintenance phase. Subjects (N=135) will be randomly assigned to one of the three treatment conditions. During the acute treatment phase, subjects assigned to CST will self-monitor using pain and sleep diaries for 8 weeks, followed by 8 weekly sessions of coping skills training. Sessions will focus on teaching the adolescent muscle relaxation techniques, distraction, activity pacing, problem solving and use of calming techniques using a treatment manual specifically developed for this age group. Subjects in the ATT condition will receive the same amount of therapist support and attention but not the active behavioral intervention. Amitriptyline dosage for subjects assigned to AMI will be stabilized at a maximum dose of 20 mg per day. Functional disability, pain intensity and depressive symptoms will be assessed before and after treatment. In the maintenance phase, subjects will continue to take their medication (or placebo) and return for either 2 CST booster sessions or 2 ATT sessions (depending on group assignment) at intervals of 8 weeks. Functional disability, pain intensity and depressive symptoms will be reassessed after the six-month maintenance phase. The long term objectives of this research are to establish effective treatments for JPFS that lead to sustained benefits in terms of improved pain control and functional abilities.

描述：少年原发性纤维肌痛综合征（JPFS）是未知病因的慢性疼痛状况，与大量的疼痛，痛苦和残疾有关。目前尚无对患有纤维肌痛的小儿患者治疗的随机临床试验。当前的应用是一项随机，安慰剂对照临床试验，该试验测试了行为和药理学治疗在JPFs治疗中的疗效。发现将药理学干预与行为改变结合的治疗方法在治疗慢性疼痛的成年人方面有效，但在小儿种群中已经研究了。在这项研究中，我们将测试疼痛应对技巧训练（CST）和低剂量阿米替林（AMI）是否有效地减少JPF青少年的功能障碍，疼痛和抑郁症状。我们将检验以下假设：应对技巧训练与低剂量阿米替林（CST+AMI）相结合，将优于应对技能培训+安慰剂（CST+安慰剂）或低剂量的阿米替林+注意力（AMI+ATT）。此外，我们将测试接受CST+AMI的受试者是否在六个月的维持阶段后会明显减轻疼痛，残疾和抑郁症状。受试者（n = 135）将随机分配到三个治疗条件之一。在急性治疗阶段，分配给CST的受试者将使用疼痛和睡眠日记进行8周的自我监测，然后每周进行8个应对技能培训。会议将专注于教授青少年肌肉放松技术，干扰，活动起搏，解决问题和使用专门为该年龄段开发的治疗手册来解决平静技术。在ATT条件下的受试者将获得相同数量的治疗师支持和注意力，而不是主动行为干预。分配给AMI的受试者的阿米替林剂量将以每天20毫克的最大剂量稳定。治疗前后，将评估功能障碍，疼痛强度和抑郁症状。在维护阶段，受试者将继续服用药物（或安慰剂），并以8周的间隔返回2个CST助推器会议或2个ATT会议（取决于小组分配）。六个月的维持阶段将重新评估功能障碍，疼痛强度和抑郁症状。这项研究的长期目标是为JPF建立有效的治疗方法，从而在改善疼痛控制和功能能力方面带来持续的好处。
