ABSTRACT
Most cases of cervical dystonia (CD) are idiopathic, and focal injections of botulinum toxin A (BoNT/A) are the treatment of choice. The objective of our study was to document the effects of long-term BoNT/A treatment in idiopathic CD patients. Fifty-eight patients with idiopathic CD were recruited from March 2001 to May 2002. Twenty-eight of the subjects were available for reassessment after seven years. During this period, all had received regular treatment with BoNT/A injections. Clinical information about patients and the severity of CD (TWSTRS and VAPS) at baseline assessment (2001-2002) and follow-up (2008-2009) was compared. Significant motor improvement was detected based on TWSTRS scale scores, which were used to analyze clinical severity (19.6±6.6 and 17.7±4.8; p<0.05). There was no improvement in the severity of cervical pain (p=0.43). In conclusion, BoNT/A was a safe and effective long-term therapy for CD.
RESUMO
A maioria dos casos de distonia cervical (DC) são idiopáticos; injeções locais com toxina botulínica A (BoNT/A) são o tratamento de escolha. O objetivo de nosso estudo foi documentar os efeitos do tratamento a longo prazo da BoNT/A em pacientes com DC idiopática. Foram selecionados 58 pacientes com DC idiopática de março de 2001 a maio de 2002. Desses pacientes, 28 estavam disponíveis para re-avaliação após sete anos. Durante esse período, todos foram submetidos a tratamento regular com injeções de BoNT/A. As informações clínicas dos pacientes e a gravidade da DC (TWSTRS e VAS) na primeira avaliação (2001-2002) e na reavaliação (2008-2009) foram comparadas. Houve uma significante melhora motora detectada pelos resultados da escala TWSTRS, usada para analisar a gravidade clínica (19,6±6,6 e 17,7±4,8; p<0,05). Não houve melhora nos resultados referentes a dor cervical (p=0,43). Em conclusão, BoNT/A foi uma terapêutica de longo prazo efetiva e segura para DC.
