Аннотация
BACKGROUND: Raynaud's phenomenon (RP) is a clinical syndrome characterized by recurrent episodes of digital vasospasm triggered by exposure to physical and chemical agents or emotional stress. Although many pharmacologic treatments have been tested, there is still no cure or gold standard therapy. Botulinum toxin treatment has been proved to reduce pain and increase arterial blood flow in treated hands of adult patients with RP.
OBJECTIVE: The aim of this study is to evaluate the efficacy of botulinum toxin A on younger than 18-year-old patients with primary and secondary RP.
MATERIALS AND METHODS: A single-center prospective study was performed, including 8 patients aged 14 to 17 years who were clinically diagnosed with primary or secondary RP. BTX was injected into each hand without sedation or anesthetic blockade. The primary outcome was pain reduction after BTX injection. Pain intensity was evaluated at baseline and in the first follow-up. Secondary outcomes included variations in the number and severity of RP episodes after the BTX injection.
RESULTS: All patients stated significant pain reduction and decreased cold sensitivity, except one patient who did not feel any changes. No patients reported any loss of strength on thumb-index finger.
CONCLUSION: BTX injection is a simple, noninvasive, and cost-effective treatment alternative, offering an important nonsurgical therapeutic option for the pediatric population. It could also help optimize the dose of other treatments used in these patients. The most commonly observed positive effect is a reduction in the pain associated with RP attacks. Further studies are needed to confirm these results.
