8个家族性特发性基底节钙化家系患者的临床研究

目的探讨8个家族性特发性基底节钙化(familial idiopathic basal ganglia calcification,FIBGC)家系患者的临床特点。方法收集8个FIBGC家系患者的临床资料,分析患者的临床检验结果、头颅CT及MRI改变、发病年龄、临床表现与患者基底节钙化体积(the volume of basal ganglia calcification,VBGC)的关系。结果家系患者和健康成员血清钙、铝、砷、钴、镁、磷、铁、甲状旁腺激素和降钙素的值比较均无显著性差异(P0.05)。8个家系包括两个近亲结婚的家系均呈现常染色体显性遗传;运动受损患者的病情严重程度与基底节区钙化的病灶大小相关;精神症状的患者有无症状与VBGC的大小无关;运动受损与精神症状的患者间发表年龄(43.954±2.473 vs.31.319±10.156 y,t=4.438,P=0.001)和VBGC(1.748±0.622 vs.0.392±0.276 cm3,t=2.518,P=0.028)比较有统计学差异。结论 8个FIBGC家系患者呈现常染色体显性遗传的特点,运动受损的患者基底节区钙化的病灶大,发病年龄较晚;精神症状的患者基底节区钙化的病灶小,发病年龄较早。

Clinical research study of Familial Idiopathic Basal Ganglia Calcification from 8 family analysis

Objective To better understand the clinical characteristics of Familial Idiopathic Basal Ganglia Calcifi?cation (FIBGC), including at the perspective of hereditary pattern, clinical test results, onset age, clinical heterogeneity and the volume of basal ganglia calcification (VBGC). Method 8 Eight FIBGC families were collected and draw family pedigrees were draw. Analysis of was conducted on the patient's clinical test results, head CT and MRI changes, onset ag?es, relationship of clinical manifestations with VBGC. Results No significant difference was found in serum calcium, alu?minum, arsenic, cobalt, magnesium, phosphorus, iron, parathyroid hormone and calcitonin concentration between the fam?ily members of patients and healthy controls (P>0.05). Family members from 8 FIBGC families including the two with consanguineous marriage manifested autosomal dominant heredity. The severity of , symptomatic s was correlated with VBGCpatients showed the same clinical manifestations in the dyskinesia family. The psychiatric symptoms was not asso? ciated with VBGC whereas patients with dyskinesia had a large VBGC. There was a significant difference in onset age be?tween patients with psychiatric symptoms and those with dyskinesia. P.atients with dyskinesia suffer larger VBGC, and is characterized by Patients with dyskinesia had relatively later onset age (43.95 ± 2.47 y) whereas those with. psychiatric symptoms hadsymptomatic patients with early onset age (31.32±10.16y). The comparison of the onset age (43.954±2.473 vs. 31.319±10.156 y, t=4.438, P=0.001) and VBGC (1.748±0.622 vs. 0.392±0.276 cm3, t=2.518, P=0.028) with symptom?atic patients between dyskinesia and psychogenic families was significant. Conclusions Eight FIBGC families manifested autosomal dominant heredity. Patients with dyskinesia suffer have a larger VBGC and are associated with a, and is char?acterized by relatively later onset age. In contrast, patients with psychiatric symptomspsychogeny is not related withhave a the small VBGC and showedand their age of onset is young. earlier onset age.
