摘要
目的 总结糖原累积病Ⅱ型（GSDⅡ型）的临床及病理学特点.方法 回顾性分析20例经肌肉活体组织检查病理诊断的GSDⅡ型患者的临床和病理资料,并对部分患者进行随访.结果 20例患者中婴儿型1例,表现为全身肌力、肌张力低下,肌萎缩,运动发育迟缓,喂养困难,反复肺部感染合并心功能不全,血清肌酸激酶778 IU/L,肌电图示肌源性损害,超声心动图示肥厚性心肌病;晚发型19例（少年型18例,成人型1例）,表现为双侧对称性四肢近端肌萎缩或呼吸肌无力等症状,呼吸肌与肢体肌受累可不平行.15例有实验室检查记录的患者中,14例血清肌酸激酶不同程度升高（208～2600 IU/L）.17例行肌电图检查,9例为肌源性损害（其中1例伴易激惹现象）,4例为可疑肌源性损害,1例为肌强直样放电,1例神经源性肌源性损害合并存在,2例正常.11例行超声心动检查,发现肥厚性心肌病1例,室间隔增厚、肺动脉高压各2例.肌活体组织病理检查均以肌纤维空泡样变为主要特征,空泡形态多样,多含有嗜碱性颗粒,过碘酸Schiff反应、酸性磷酸酶染色阳性反应明显.结论 GSDⅡ型在临床上表现为慢性肌病,以躯干肌和呼吸肌受累常见.多数患者血清肌酶轻度升高,肌肉病理检查有明显空泡样变,有助于确诊.
Objective To summarize the clinical and pathological features of glycogen storage disease （GSD） type Ⅱ. Methods The clinical and pathological data of the 20 GSD type Ⅱ patients were reviewed. Results One patient with infantile-onset mainly presented hypotonia, muscle weakness, feeding difficulties, pulmonary infection and cardiomyopathy insufficiency and increase of serum creatine kinase （778 IU/L） and echographic evidence of hypertrophic cardiomyopathy were detected. Electromyography studies indicated a definite myopathy. Nineteen cases were late-onset, presenting a slowly progressive proximal myopathy with truncal involvement or with symptoms dominated by respiratory insufficiency. Not all muscles were equally affected. Increase of serum creatine kinase （208-2600 IU/L） was detected in 14 patients and normal level in 1 patient. Electromyography studies indicated a definite myopathy in 9 patients,with abnormal irritability in 1 patient and susceptible in 4 patients and myotonic discharge in 1 patient and no abnormalities in 2 patients. Echographic evidence of thickening of the interventricular septum and pulmonary hypertension were detected in 2 patients respectively. The common light microscopic feature of all case was a vacuolar myopathy with high glycogen content and acid phosphatase activity in the vacuoles. Conclusions GSD type Ⅱ often presents slowly progressive myopathy which often affect the toro and respiratory muscles.In most patients the serum creatine kinase level is elevated slightly. Muscle biopsy is of use to make the definite diagnosis of this disease.
