摘要
目的：探讨dysferlinopathy患者大腿肌肉水肿及脂肪化规律及其与临床表现之间的关系。方法收集2005-2013年就诊于北京大学第一医院的32例dysferlinopathy患者，包括13例肢带型肌营养不良2B型（limb girdle muscular dystrophy type 2B，LGMD2B）、13例Miyoshi肌病、4例近远端肌病及2例高肌酸激酶血症患者。对患者进行改良Gardner-Medwin and Walton （ GM-W）评分和大腿肌肉MRI检查，对MRI的脂肪化和水肿改变进行评分。计算LGMD2B和Miyoshi肌病患者在发病年龄、病程、GM-W评分、肌肉脂肪化和水肿评分以及分布模式之间的差异，并分析所有患者大腿肌肉脂肪化和水肿总评分与其病程、GM-W评分之间的相关性。结果所有患者的GM-W中位数评分为4.00（2.00，5.00）分，其中LGMD2B为4.00（3.00，4.50）分，Miyoshi肌病为4.00（2.00，5.00）分。30例患者（93.75％）出现肌肉脂肪化，在LGMD2B和Miyoshi肌病患者中分布模式相同，骨骼肌脂肪化平均总评分为（28.20±12.86）分，其中 LGMD2B 为（28.50±13.03）分，Miyoshi 肌病为（29.00±12.63）分。26例患者（81.25％）存在肌肉水肿，在LGMD2B和Miyoshi肌病患者中分布模式相同，骨骼肌水肿平均总评分为（18.36±13.60）分。其中LGMD2B为（22.88±11.59）分，Miyoshi 肌病为（16.77±13.80）分。两组患者在发病年龄、病程、GM-W评分、肌水肿和脂肪化评分之间差异无统计学意义。所有患者的肌肉脂肪化总评分与其GM-W评分（ rs ＝0.737，P＝0.000）和病程（ rs ＝0.637， P＝0.000）均呈正相关。结论大腿肌肉脂肪化和水肿均是dysferlinopathy 患者常见的MRI改变，主要临床亚型具有类似的影像学改变。肌肉脂肪化可用于该病的进展评估。
Objective To investigate the characteristics of muscle edema and fatty infiltration in thighs and relationship with clinical symptoms in Chinese patients with different phenotypes of dysferlinopathy.Methods A total of 32 patients were enrolled , including 13 limb-girdle muscular dystrophy 2B （LGMD2B）, 13 Miyoshi myopathy （MM）, 4 proximodistal myopathy and 2 hyper-creatine-kinase-emia.Clinical symptoms were evaluated using modified Gardner-Medwin and Walton （ GM-W） score.Muscle MRI was performed in thighs to observe fatty infiltration and edema.We then compared the age of onset , disease duration, GM-W score, muscle edema and muscle fatty infiltration between LGMD 2B and MM groups,and the relationship of muscle edema score and fatty infiltration score with disease duration and GM-W score in all patients.Results The median GM-W score was 4.00 （2.00,5.00） in all patients, 4.00 （3.00,4.50）in LGMD2B and 4.00（2.00,5.00）in MM, respectively.Muscle fatty infiltration appeared in 30 cases （93.75%）, with the same pattern in LGMD2B and MM.The mean fatty infiltration score was 28.20 ±12.86 in all patients, 28.50 ±13.03 in LGMD2B and 29.00 ±12.63 in MM, respectively.Muscle edema appeared in 26 cases （81.25%） with same pattern in LGMB2B and MM.The mean edema score was＆nbsp;18.36 ±13.60 in all patients, 22.88 ±11.59 in LGMD2B and 16.77 ±13.80 in MM.The age of onset , disease duration, GM-W score, muscle fatty infiltration and edema score were not significantly different between LGMD2B and MM patients.Muscle fatty infiltration score significantly correlated with GM-W score （rs=0.737,P=0.000） and disease duration （rs=0.637,P=0.000）.Conclusions Fatty infiltration and edema in thigh muscles are very common in patients with dysferlinopathy , with similar radiological changes in main subtypes.The muscle fatty infiltration can be used as a predictor of disease progression.
