目的:确定中文版北极星移动评价量表(NSAA)应用在Duchenne型肌营养不良症(DMD)患儿的信度和效度。方法:纳入对象为2014年1月至2016年1月在复旦大学附属儿科医院康复科接受功能评估的DMD患儿,均经基因检测或肌肉活检明确诊断,能独立行走≥10 m,无严重认知障碍。2名物理治疗师同时对DMD患儿进行测试,检验不同测试者间的信度;同一评价者在第1次评价后3~7 d进行第2次评价,检测重测信度;采用《国际功能、残疾和健康分类》儿童和青少年版(ICF-CY)的类目编码与NSAA的项目概念进行关联,确定NSAA的内容效度;通过分析NSAA的分值与6 min步行距离的相关性进行关联效度分析。结果:2个治疗师对20名DMD男孩的不同测试结果间的信度分析显示,NSAA原始分和线性分信度ICC分别为0.96和0.97;1名治疗师前后3~7 d重测16名DMD男孩,NSAA的原始分和线性分具有很好的重测信度(ICC=0.96);NSAA17个项目共与8个ICF-CY编码发生了20次关联,8个编码都属于d4(移动)下属,表明NSAA的评价内容主要聚焦于DMD患儿活动能力中的移动能力;143例DMD男孩的NSAA原始分和线性分与6min步行距离具有中等程度的相关性(r分别为0.40和0.38)。结论:中文版NSAA量表无论是原始分还是线性分都具有良好的心理测量学特性,结合其他的评价指标,NSAA可以有效地评价中国DMD男孩的活动能力。 相似文献

Duchenne型肌营养不良基因治疗研究进展 总被引:1,自引:1,他引:0
Duchenne型肌营养不良(DMD)是由编码抗肌萎缩蛋白的DMD基因突变导致的X连锁隐性遗传病。它的特点是进行性肌无力和因缺乏抗肌萎缩蛋白而导致的骨骼肌和心肌退化。患儿多于2~5岁起病,常在20岁左右死于心力衰竭或呼吸功能不全。目前,临床上多采用支持疗法改善疾病症状,但并不能改变疾病的最终结局。基因治疗的兴起为该病的治愈提供了希望。本文总结了DMD的基因替代疗法,包括腺相关病毒介导的DMD基因转导技术、肌营养不良蛋白相关蛋白(utrophin)上调技术和成簇规律间隔的短回文重复序列基因编辑技术的研究进展,并为解决腺相关病毒载量、转基因产物的长期有效表达、utrophin蛋白表达量问题提出的建议进行综述,为研究者们进一步研究提供参考。 相似文献

目的 研究不同年龄阶段Duchenne型肌营养不良患儿肌细胞膜上DGC关联复合物蛋白的表达.方法 将24例已确诊的Duchenne型肌营养不良患儿根据儿童发育年龄分成3组,0.5~3岁为幼儿期组,~6岁为学龄前期组,~13岁为学龄期组.利用免疫组织化学方法对肌细胞膜上与抗肌萎缩蛋白(dystrophin)组成相关DGC复合体的蛋白进行分析.结果 dystrophin蛋白的缺失可引起不同年龄阶段的肌细胞膜上α-SG、β-SG、γ-SG、δ-SG、β-DG和dysferlin不同程度的缺乏或完全缺乏;肌细胞膜七的nNOS蛋白在3组中完全缺乏,而caveolin-3蛋白表达增加.结论 与dystrophin组成相关DGC复合体的蛋白在不同年龄阶段Duchenne型肌营养不良患儿均呈现不同程度的缺乏或完全缺乏,这些蛋白的缺乏可能发生在胚胎时期,而caveolin-3蛋白表达增高与肌纤维再生过程有关. 相似文献

Aim We evaluated ambulatory patients with Duchenne muscular dystrophy from the cardiovascular standpoint and studied the correlation between the results of electrocardiographic (ECG) findings, left ventricular ejection fraction (LVEF), troponin T and N‐terminal pro‐brain natriuretic peptide (NT‐proBNP) levels and patients' North Star Ambulatory Assessment scores. Methods: Fifty patients of ages 6–12 (8.9 ± 2.8) were enrolled in this cross‐sectional study. Cardiac evaluation included electrocardiography, echocardiography and cardiac enzyme tests. Results North Star scores ranged from 6/34 to 34/34. Twenty‐eight patients (56%) had ECG changes. The most frequently seen ECG abnormalities were short PR interval (14%, n= 7), right ventricular hypertrophy (16%, n= 8), prolonged QTc interval (10%, n= 5), prominent Q wave (10%, n= 5) and T wave inversion (44%, n= 22). In 10 patients (20%), LVEF was below 55%, troponin T and NT‐proBNP levels were significantly elevated (P= 0.003 and P < 0.001, respectively). When North Star scores were compared to patients' age, enzyme levels, ECG and echocardiographic results, we discovered negative correlation with age (P < 0.001) and troponin T levels (P= 0.02) and positive correlation with LVEF (P= 0.02). Conclusion Patients with North Star scores of ≤16 are more at risk of developing cardiomyopathies. Troponin T is a cardiac index that can be used for evaluating myopathic patients and it seems to be correlated with the proBNP levels and LVEF values. 相似文献

Summary A total of 18 male patients with Duchenne muscular dystrophy (DMD), aged 8–29 years (mean, 15.7 years), were prospectively studied to assess the cardiomyopathy associated with DMD, using clinical parameters and noninvasive cardiovascular investigations: electrocardiogram (ECG), Holter monitoring, and echocardiography. In addition, five clinical tests of cardiovascular autonomic function were used to assess the role of the autonomic nervous system in the pathogenesis of dysrhythmias.The majority of subjects were asymptomatic, but four had abnormal physical findings. All had abnormal ECG, the commonest abnormality (in 16) being tall R waves or increased R/S ratios in the right precordial leads; 14 had abnormal findings on echocardiography, including three with poor left ventricular function and five with mitral valve prolapse (MVP). Labile abrupt sinus tachycardia was present in 11, and four had high-grade ventricular ectopy. None had definite clinical evidence of autonomic dysfunction.The cardiomyopathy of DMD appears to be unrelated to disease severity. However, abnormal Q waves or Q/R ratios in ECG leads I, a VL, and V5–V6 are significantly related to young age (p<0.05), and high-grade ventricular ectopy occurred significantly more frequently (p<0.05) in older subjects (>15 years). Dysrhythmias were not related to the presence of MVP, poor left ventricular function, or autonomic dysfunction. 相似文献

Background: Assessing autonomic function is important for patients with chronic heart failure, but the way that autonomic function changes in patients with Duchenne muscular dystrophy (DMD) and correlates with other clinical parameters during their young age is not clearly known. Methods: Heart rate variability (HRV) during ambulatory electrocardiogram (ECG) was performed in 57 DMD patients (130 recordings) who were not receiving medication (mean age 15.3 ± 4.5 years). The data were compared with the serum levels of brain natriuretic peptide (BNP), the shortening fraction (SF) of the left ventricle on echocardiography, and simple parameters of heart rate from 24 h ambulatory ECG. Results: Among four parameters of HRV measurements (high frequency [HF]; percentage of adjacent normal R‐R intervals that were >50 ms different for the entire 24 h recording [%RR50]; ratio of low to high frequency [LF/HF]; and standard deviation for all normal R‐R intervals for the entire 24 h recording [SDNN]), SDNN was most frequently abnormal. Even when SF was normal, a significant percentage of patients exhibited, abnormal parasympathetic activity (HF, %RR50: 74%, 78%, respectively), sympathetic activity (LF/HF, 43%), and SDNN (96%). Similarly, even if serum BNP levels were normal, 86%, 89%, 59%, and 97% of the patients displayed abnormal autonomic function on these measurements, respectively. Mean heart rate at night most accurately predicted abnormality of SDNN. When the cut‐off point for mean heart rate at night was 71 beats/min, the sensitivity and specificity of this parameter for predicting abnormal SDNN was 94% and 85%, respectively (P < 0.0001). Conclusion: In DMD, autonomic function, especially SDNN, was frequently abnormal, although conventional clinical examinations of cardiac function (BNP levels and SF) were normal. It is proposed that mean heart rate during night could be used as a simple measurement for evaluation of autonomic function. 相似文献

BACKGROUND:
Ventilators for home use, manual and mechanically assisted coughing techniques, and the services of in-home respiratory therapists are options for youth with Duchenne muscular dystrophy (DMD). Evidence supports the use of these modalities, but there seems to be few youth who are receiving these therapies. Is there a knowledge transfer issue? Is there a lack of resources? What is the best way to discuss the issues? What do youth and parents want?OBJECTIVE:
To determine practices, attitudes and beliefs regarding the timing and content of client/family communication related to ventilatory support decisions for individuals with DMD.METHODS:
A questionnaire was sent to all 19 children’s treatment centres in Ontario. The lead clinician responded on behalf of his or her centre. Another questionnaire was given to 11 families who attended a parent support meeting.RESULTS:
Respondents from the treatment centres who provide services for youth with DMD indicated that there are resources in terms of personnel and an obligation to provide information about ventilatory support, but provision of information is often late and/or inconsistent. The family respondents wanted more information and they wanted it earlier than they are currently receiving it.CONCLUSIONS:
Parents and youth dealing with DMD have many resources at their disposal in Ontario. The evidence is clear that there are long-term health benefits to providing ventilatory support as well as instruction in coughing assistance. Due to the classical nature of disease progression in DMD, information should be provided within reasonable timelines. 相似文献16.

Deep venous thrombosis (DVT) is an uncommonly encountered condition in childhood and, as a consequence, the diagnosis may be overlooked. We describe the first two cases of DVT occurring in children with Duchenne muscular dystrophy. Both brothers were wheel-chair-bound for protracted periods. The first case occurred following spinal fusion for scoliosis. The second occurred spontaneously following immobilisation in hospital while undergoing investigation for a ureteric stone. Serological investigations to outrule an underlying thrombogenic cause showed no deficiency of protein C or antithrombin III nor the presence of lupus anticoagulant in either patient. The presence of flaccid lower extremities resulting in prolonged immobilisation combined with an ineffective muscle pump for venous return may have predisposed the patients in our series. The issue of prophylaxis should now be actively considered in such patients in high-risk circumstances.
