Intrathecal baclofen therapy for severe spasticity in an adult with tethered cord syndrome: a case report

Background Patients with tethered cord syndrome often suffer severe spasticity. To the best of our knowledge, intrathecal baclofen (ITB) therapy in a patient with tethered cord syndrome has not been reported previously. We describe a case in which ITB therapy was useful for treating severe spasticity in an adult with tethered cord syndrome. Case presentation We present the case of a 50-year-old Japanese woman with tethered cord syndrome and related conditions suffering from severe spasticity and pain in the lower limbs. She was born with a lumbosacral myelomeningocele, which was closed in the neonatal period. For 4–5 years before this presentation, spasticity in the lower limbs had been exacerbated without any obvious cause. She received rehabilitation and pharmacotherapy from a local doctor, but symptoms were unimproved, and her previous doctor referred her to this department. A test with 50 μg of intrathecally delivered baclofen showed total relief of spasticity and pain, so a pump was implanted for continuous baclofen delivery. During 24 months of follow-up, spasticity has remained under excellent control with baclofen at 38.5–41.0 μg/day. Conclusions ITB therapy proved extremely effective in this adult with severe spasticity from tethered code syndrome.

Treatment of spasticity in children and adolescents with cerebral palsy in Northern Europe: a CP-North registry study

Background Spasticity is present in more than 80% of the population with cerebral palsy (CP). The aim of this study was to describe and compare the use of three spasticity reducing methods; Botulinum toxin-A therapy (BTX-A), Selective dorsal rhizotomy (SDR) and Intrathecal baclofen therapy (ITB) among children and adolescents with CP in six northern European countries. Methods This registry-based study included population-based data in children and adolescents with CP born 2002 to 2017 and recorded in the follow-up programs for CP in Sweden, Norway, Denmark, Iceland and Scotland, and a defined cohort in Finland. Results A total of 8,817 individuals were included. The proportion of individuals treated with SDR and ITB was significantly different between the countries. SDR treatment ranged from 0% ( Finland and Iceland) to 3.4% (Scotland) and ITB treatment from 2.2% (Sweden) to 3.7% (Denmark and Scotland). BTX-A treatment in the lower extremities reported 2017–2018 ranged from 8.6% in Denmark to 20% in Norway (p < 0.01). Mean age for undergoing SDR ranged from 4.5 years in Norway to 7.3 years in Denmark (p < 0.01). Mean age at ITB surgery ranged from 6.3 years in Norway to 10.1 years in Finland (p < 0.01). Mean age for BTX-A treatment ranged from 7.1 years in Denmark to 10.3 years in Iceland (p < 0.01). Treatment with SDR was most common in Gross Motor Function Classification System (GMFCS) level III, ITB in level V, and BTX-A in level I. The most common muscle treated with BTX-A was the calf muscle, with the highest proportion in GMFCS level I. BTX-A treatment of hamstring and hip muscles was most common in GMFCS levels IV-V in all countries. Conclusion There were statistically significant differences between countries regarding the proportion of children and adolescents with CP treated with the three spasticity reducing methods, mean age for treatment and treatment related to GMFCS level. This is likely due to differences in the availability of these treatment methods and/or differences in preferences of treatment methods among professionals and possibly patients across countries.

An efficient multidisciplinary approach in a pregnant patient with hereditary spastic paraparesis treated by intrathecal baclofen therapy: A case report

Literature regarding cases of pregnant patients with hereditary spastic paraparesis (Strumpell-Lorrain disease) and those treated by intrathecal baclofen therapy is sparse. There are currently no specific guidelines to manage pregnancy and delivery in these patients. A 42-year-old woman presented to our clinic with hereditary spastic paraparesis and was treated with intrathecal baclofen for spasticity. She conceived twice and delivered successfully by caesarean section under subarachnoid anaesthesia. The two pregnancies had favourable outcomes with no increase in spasticity and no problems encountered with the intrathecal device. In this report, we discuss the evolution of both pregnancies and the anaesthetic management for deliveries in the presence of an intrathecal catheter. Keywords: Caesarean section; case report; hereditary spastic paraparesis; intrathecal baclofen; pregnancy.

Intrathecal baclofen therapy for Lesch-Nyhan disease: illustrative case

BACKGROUNDLesch-Nyhan disease (LND) is a very rare metabolic disorder involving the purine salvage pathway. LND manifests hyperuricemia, self-mutilation, cognitive impairment, and movement disorders such as spasticity and dystonia, whose control is difficult pharmaceutically.OBSERVATIONSIntrathecal baclofen (ITB) therapy was received by a 22-year-old male for generalized dystonia. His paroxysmal abnormal dystonic posturing reduced after surgery, making the task of caregivers easier despite the unchanged assignment on the dystonia scale during a follow-up period of 4 years.LESSONSITB may be a safe and feasible option for dystonic symptoms and difficulty with nursing care in patients with LND.
