老年人Meige综合征的A型肉毒毒素重复治疗观察

目的 探讨老年人Meige综合征的A型肉毒毒素(BTX-A)重复治疗的疗效及安全性.方法 对48例老年Meige综合征患者进行BTX-A重复治疗12次或12次以上,在第1次、第6次及第12次治疗前及治疗后第2周和第4周根据Cohen标准对患者进行肌肉痉挛程度分级,前后对照评价疗效,同时观察治疗后的起效时间、疗效持续时间及不良反应,比较第1次、第6次及第12次治疗的疗效、起效时间、疗效持续时间及不良反应之间的差别. 结果 3次治疗的显效率均为100%,起效时间分别为(3.5±1.7)d、(3.18±1.76)d和(3.3±1.9)d,疗效持续时间分别为(25.4±2.1)周、(24.6±2.3)周和(25.4±1.8)周,不良反应发生率分别为8.3%(4/48)、6.3%(3/48)和8.3%(4/48),差异均无统计学意义(P>0.05). 结论 老年人Meige综合征BTX-A重复治疗远期疗效显著而稳定、安全.

Observation of curative effect of repeated botulinium toxin type A treatment for Meige's syndrome in senile people

Objective To investigate the efficacy and safety of repeated botulinum toxin type A (BTX-A) treatment for Meige's syndrome in senile people. Methods Forty-eight senile patients with Meige's syndrome received BTX-A treatment for twelve times or over. The improvements of spasm were evaluated before and after the first, the sixth and the twelfth treatment according to Cohen's criteria. The onset time, effective duration and side effects were studied and compared among the three times treatments. Results The obvious effective rate of the three times treatment were all 100%. The average onset time of the three times treatments were (3.5± 1.7)days,(3.2±1.8)days and (3.3±1.9)days, and the average effective duration were (25.4±2.1)weeks,(24.6±2.3)weeks and (25.4±1.8)weeks, respectively. The incidences of side effects were 8. 3% (4/48), 6.3(3/48)%and 8.3%(4/48), respectively. All the differences were not statistically significant(P>0.05). Conclusions Repeated BTX-A treatment is an effective and safe method for Meige's syndrome in senile people.
