Effect of continuous intrathecal baclofen therapy in children: a systematic review.

ABSTRACT: AIM:To investigate the effects of continuous intrathecal baclofen (ITB) therapy in children with cerebral palsy (CP) and other neurological conditions. METHOD:This systematic review was conducted using standardized methodology, searching four electronic databases (PubMed, Embase, CINAHL, Cochrane Library) for relevant literature published between inception and September 2017. Included studies involved continuous ITB as an intervention and outcome measures relating to all International Classification of Functioning, Disability and Health: Children and Youth (ICF-CY) components. RESULTS:Thirty-three studies were identified, of which one, including 17 children with spastic CP, produced level II evidence, and the others, mainly non-controlled cohort studies, level IV and V. Outcomes at body function level were most frequently reported. Results suggest continuous ITB may be effective in reducing spasticity and dystonia in CP, as well as other neurological conditions, and may improve the ease of care and quality of life of children with CP, but the level of evidence is low. INTERPRETATION:Despite three decades of applying ITB in children and a relatively large number of studies investigating the treatment effects, a direct link has not yet been demonstrated because of the low scientific quality of the primary studies. Further investigation into the effects of continuous ITB at all levels of the ICF-CY is warranted. Although large, controlled trials may be difficult to realize, national and international collaborations may provide opportunities. Also, multicentre prospective cohort studies with a long-term follow-up, employing harmonized outcome measures, can offer prospects to expand our knowledge of the effects of continuous ITB therapy in children. WHAT THIS PAPER ADDS:There is low-level evidence for continuous intrathecal baclofen (ITB) in children with cerebral palsy. Continuous ITB is effective in reducing spasticity and dystonia in non-controlled cohort studies. Evaluation of individual goals and systematic assessment of long-term effects in large cohort studies are required.

Project description:BackgroundSevere spasticity may negatively impact functionality and quality of life after spinal cord injury (SCI). Intrathecal baclofen treatment (IBT) is effectively used to manage severe spasticity and reduce comorbidities. However, long-term IBT may have a negative effect on bone mineral content (BMC), bone mineral density (BMD) and body composition (such as percentage fat mass and lean body mass). We demonstrated the negative effects of long-term IBT use in a single case compared with two non-IBT users.Case summaryA 46-year old Caucasian male Veteran (case) with a 21 year history of complete tetraplegia (complete C6 SCI) was implanted with IBT for 20 years. The case was matched to two participants with different time since injuries [2 (match 1) and 13 (match 2) years] without IBT. Knee BMC and BMD at the epiphysis and metaphysis of the distal femur and proximal tibia were evaluated using dual knee and the dual femur modules of GE Lunar iDXA software. Total and leg body composition assessments were also conducted for the three participants. Potential effect of long-term IBT was demonstrated by changes in BMD, consistent with bone demineralization, at the distal femur and proximal tibia and changes in percentage fat mass and lean mass of legs. The case showed 113% lower BMD at the distal femur, and 78.1% lower at the proximal tibia compared to match 1, moreover the case showed 45% lower BMD at the distal femur, and no observed changes at the proximal tibia compared to match 2. The case had 27.1% and 16.5% greater leg %fat mass compared to match 1 and match 2, respectively. Furthermore, the case had 17.4% and 11.8% lower % leg lean mass compared to match 1 and match 2, respectively.ConclusionLong-term IBT may impact bone health and body composition parameters in persons with complete SCI. It may be prudent to encourage regular screening of individuals on long-term IBT considering the prevalence of osteoporosis related fractures, cardiovascular diseases, and metabolic disorders in this population.
