The treatment of focal dystonia and muscle spasm with Botox and CBTX-A
Objective To confirm and compare the therapeutic efficacies of CBTX-A (made by Lanzhou Biological Products Institute, China) and Botox (from Allergan Inc, US) for focal dystonia and other neurological disorders characterized by involuntary or abnormal muscle contractions. Methods We treated 785 patients with medically intractable focal dystonia and muscle spasm in two groups, 192 cases with Botox and 593 cases with CBTX-A. A total of 1393 treatments were given over a 4-year period. The results of a prospective open study were analyzed. Results Considerable improvement of symptoms was observed in all patients but 11 (1.4%)with either Botox or CBTX-A, 30.4% were rated as excellent, 57.8% as marked improvement, 8.9% as moderate improvement. The side effects were usually minor and transient. The most concerned complications after injections were ptosis and dysphagia. There was no significant difference in the clinical effects between this two kinds off preparation, including the latency of response, maximal benefit, duration of improvement. Patients” subjective assessments were similar too. But the requested dose of Chinese preparation which produced the similar effects was statistically higher than that of Botox; and skin rash appeared within a few days after injections in 5 cases of CBTX-A group, while none of Botox group, no statistical differences in the other adverse reaction between them. Treatment was needed to repeat in most patients to maintain the effects. The pretreatment scores of the reinjection were slightly lower. Moreover, a progressive reduction in posttreatment scores was observed in HFS and CD, with the latency of response, duration ofimprovement and doses unchanged or doses lower than the initial one. Conclusion The injections of both two kinds of preparation were simple and effective out-patient treatment for the patients with focal dystonia and muscle spasm. Chinese preparation is a little less powerful but much cheaper than Botox. Although a few patients were allergic to CBTX-A, it is still a valuable treatment for most patients in China
