背景:杜氏肌营养不良(DMD)的特征是功能迅速下降。目前可用的治疗方案旨在延缓疾病进展或稳定身体功能。为了帮助医疗保健提供者了解影响患者的疾病症状,这项研究探讨了儿童的身体机能,日常生活活动(ADL),以及接受eteplirsen后与健康相关的生活质量(HRQoL),有51外显子突变的DMD患者需要每周输注一次.
方法:15名男性DMD患者的照顾者参加了60分钟,半结构化面试。开放式提问探讨了自eteplirsen开始以来儿童状况或能力维持的变化。
结果:患有DMD的儿童(年龄7-15岁[平均10.9];访谈时的类固醇治疗,n=8;自eteplirsen开始3-24个月以来的时间[平均14.9])被护理人员描述为门诊(n=9)和非门诊(n=6)。非卧床儿童的照顾者报告步行能力改善或维持(n=7/9),运行(n=6/9),并使用楼梯(n=4/9)。两名护理人员报告了使用楼梯的持续下降。在上肢功能方面,近一半的护理人员报告了精细运动的改善或维持(n=7/15),一名护理人员注意到持续下降。描述了ADL的后续改进或维护。疲劳的改善或维护(n=9/15),肌肉无力(n=7/15),和疼痛(n=6/15)报告,尽管一些护理人员描述了持续下降(n=3/15疲劳,n=1/15肌肉无力,n=2/15疼痛)。重要的是,大多数报告能力维持的护理人员认为这是一个积极的结果(n=6/9).
结论:这项探索性研究表明,大多数照顾者在孩子的身体机能方面都有改善或维持,ADLs,和自eteplirsen启动以来的HRQoL,他们认为这是一个积极的结果。
杜氏肌营养不良症(DMD)是一种罕见的疾病,其特征是进行性肌肉无力。早期,这种弱点表现为行走困难,但是最终孩子们失去了行走的能力,发展脊柱弯曲,心脏和肺部肌肉出现问题。患有DMD的人体内缺少一种称为肌营养不良蛋白的关键蛋白质。埃特普利森是每周一次,静脉治疗被批准用于治疗患有特定DMD基因拼写错误的人。治疗的目标是减缓疾病并延迟失去行走能力或需要帮助呼吸的时间。15名患有DMD的儿童的看护人参加了60分钟的电话采访。护理人员被问及有关儿童DMD症状以及这些症状如何影响儿童日常生活的问题。照顾者讨论了他们的孩子在接受eteplirsen治疗时的经历以及自治疗开始以来的变化。看护者描述了他们孩子的肌肉无力以及这如何影响他们的运动(例如,使用楼梯,跑步或走路)。自从开始接受eteplirsen治疗后,所有看护人都报告说他们孩子的身体功能部分有所改善或维持,日常生活活动(例如,运动/休闲,穿衣服和自我保健),和症状(例如,肌肉无力,疼痛和疲劳),尽管也报告了一些下降(例如,身体机能,穿好衣服,自我照顾,肌肉无力,疼痛和疲劳)。结果提供了对正在接受eteplirsen治疗的DMD儿童的身体功能和生活质量的见解。然而,需要更多的研究来充分了解eteplirsen对这些经历的影响.
BACKGROUND: Duchenne muscular dystrophy (DMD) is characterized by rapid functional decline. Current available treatment options aim to delay disease progression or stabilize physical function. To aid in healthcare providers\' understanding of the symptoms of disease that impact patients\' experience, this study explored children\'s physical functioning, activities of daily living (ADLs), and health-related quality of life (HRQoL) after receiving eteplirsen, a weekly infusion indicated for individuals with DMD with exon 51 skip-amenable mutations.
METHODS: Fifteen caregivers of male individuals with DMD participated in a 60-min, semi-structured interview. Open-ended questioning explored changes in the children\'s condition or maintenance in abilities since eteplirsen initiation.
RESULTS: Children with DMD (age 7-15 years [mean 10.9]; steroid treatment at interview, n = 8; time since eteplirsen initiation 3-24 months [mean 14.9]) were described by caregivers as ambulatory (n = 9) and non-ambulatory (n = 6). Caregivers of ambulatory children reported improvements or maintenance of walking ability (n = 7/9), running (n = 6/9), and using stairs (n = 4/9). Continued decline in using stairs was reported by two caregivers. In upper-limb functioning, improvements or maintenances in fine-motor movements were reported by nearly half of all caregivers (n = 7/15), with one caregiver noting a continued decline. Subsequent improvements or maintenances in ADLs were described. Improvements or maintenances in fatigue (n = 9/15), muscle weakness (n = 7/15), and pain (n = 6/15) were reported, although some caregivers described a continued decline (n = 3/15 fatigue, n = 1/15 muscle weakness, n = 2/15 pain). Importantly, most caregivers who reported maintenances in ability perceived this as a positive outcome (n = 6/9).
CONCLUSIONS: This exploratory study indicated that most caregivers perceived improvements or maintenances in aspects of their child\'s physical functioning, ADLs, and HRQoL since eteplirsen initiation, which they perceived to be a positive outcome.
Duchenne muscular dystrophy (DMD) is a rare disease characterized by progressive muscle weakness. Early on, this weakness presents as difficulty walking, but eventually children lose the ability to walk, develop spinal curvature, and experience problems with the heart and lung muscles. People with DMD are missing a key protein in their bodies called dystrophin. Eteplirsen is a weekly, intravenous treatment approved to treat people with a specific DMD genetic misspelling. The goal of the treatment is to slow down the disease and delay the time to losing ability to walk or needing help breathing. Fifteen caregivers of children living with DMD participated in a 60-min telephone interview. Caregivers were asked questions about the child’s DMD symptoms and how those symptoms impact the child’s daily life. Caregivers discussed their child’s experience while receiving eteplirsen treatment and changes since the start of treatment. Caregivers described their child’s muscle weakness and how this has affected their movements (e.g., using stairs, running or walking). Since starting eteplirsen treatment, all caregivers reported some improvement or maintenance in parts of their child’s physical functioning, activities of daily living (e.g., sports/leisure, getting dressed and self-care), and symptoms (e.g., muscle weakness, pain and fatigue), even though some decline was also reported (e.g., physical functioning, getting dressed, self-care, muscle weakness, pain and fatigue). The results provide insights into physical functioning and quality of life of children with DMD who are receiving eteplirsen. However, more research is needed to fully understand the impact of eteplirsen on these experiences.
