Abstract
The aim of this study was to analyze the impact of human umbilical cord-derived MSCs (hUC-MSCs) on motor function in children with cerebral palsy (CP). The study enrolled 152 children with CP who received up to two courses of five hUC-MSCs injections. Children's motor functions were assessed with the Gross Motor Function Measure (GMFM), 6-Minute Walk Test (6-MWT), Timed Up and Go test (Up&Go test), and Lovett's test, and mental abilities were assessed with the Clinical Global Impression (CGI) scale. Data collected at visit 1 (baseline) and visit 5 (after four injections) were analyzed retrospectively. After four hUC-MSCs administrations, all evaluated parameters improved. The change in GMFM score, by a median of 1.9 points (IQR: 0.0-8.0), correlated with age. This change was observed in all GFMCS groups and was noticed in all assessed GMFM areas. A median increase of 75 m (IQR: 20.0-115.0) was noted on the 6-MWT, and this correlated with GMFM score change. Time on the Up&Go test was reduced by a median of 2 s (IQR: -3 to - 1) and the change correlated with age, GMFM score at baseline, and the difference observed on the 6-MWT. Results of Lovett's test indicated slight changes in muscle strength. According to the CGI, 75.5% (96/151) of children were seriously (level VI) or significantly ill (level V) at the 1st visit, with any improvement observed in 63.6% (96/151) of patients at the 5th visit, 23.8% (36/151) with improvement (level II) or great improvement (level I). In conclusion, the application of hUC-MSCs generally enhanced functional performance, but individual responses varied. The therapy also benefited children with high level of disability but not to the same extent as the initially less disabled children. Although younger patients responded better to the treatment, older children can also benefit. Trial Registration 152/2018/KB/VII and 119/2021/KB/VIII. Retrospective registration in ClinicalTrials: ongoing.

Klein C, Gouron R, Barbier V. Effects of botulinum toxin injections in the upper limbs of children with cerebral palsy: A systematic review of the literature. Orthop Traumatol Surg Res 2024; 110:103578. [PMID: 36754169 DOI: 10.1016/j.otsr.2023.103578] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/16/2022] [Revised: 10/20/2022] [Accepted: 11/03/2022] [Indexed: 02/10/2023]
Abstract
BACKGROUND Spasticity is a common motor disorder in children with cerebral palsy (CP). Upper limb CP impairment has a significant negative impact on daily activities. Botulinum toxin (BTX-A) injections are widely used to reduce spasticity, but their effectiveness is not well-defined. We performed a systematic review of literature to answer questions about the effectiveness of BTX-A injections in the upper limb in children with CP. METHODS A systematic review of literature was conducted according to PRISMA guidelines. Eligible studies were randomized controlled trials with a high level of evidence on BTX-A upper limb injections in children. The outcomes analyzed included the study population, spasticity, quality of movement, activity limitations, quality of life, pain, appearance and side effects. RESULTS A total of 24 studies were included. The number of patients included was 1358 with a mean age between 3 and 11years. Improvement after BTX-A injection compared to the control group was observed for spasticity (n=10/19 studies), bimanual activities (Assisting Hand Assessment) (n=3/7), activity limitations (n=6/11), pain (n=2/2) and appearance (n=2/2). No study found an improvement in quality of life. Side effects were described in 16 studies and were moderate in all cases. CONCLUSION This review of literature showed that BTX-A injections can improve spasticity and particularly activity limitations when reasonable objectives are established. LEVEL OF EVIDENCE IV, systematic review.

Abstract
Botulinum toxin type-A (BoNT-A) has emerged as a key therapeutic agent for the management of spasticity. This paper presents a comprehensive bibliometric and visual analysis of research concerning BoNT-A treatment of spasticity to elucidate current trends and future directions in this research area. A search was conducted in the Web of Science database for articles focused on the use of BoNT-A in spasticity published between 2000 and 2022. We extracted various metrics, including counts of publications and contributions from different countries, institutions, authors, and journals. Analytical methods in CiteSpace were employed for the examination of co-citations, collaborations, and the co-occurrence of keywords. Our search yielded 1489 publications. Analysis revealed a consistent annual increase in research output. The United States, United Kingdom, and Italy were the leading contributors. The top institution in this research was Assistance Publique Hopitaux, Paris. The journal containing the highest number of relevant publications was Toxins. Key frequently occurring keywords were 'stroke', 'cerebral palsy', 'adult spasticity', and 'upper extremity'. This study identified 12 clusters of keywords and 15 clusters of co-cited references, indicating the main focus areas and emerging themes in this field. This study comprehensively analyzed and summarized trends in BoNT-A research in the field of spasticity over the past 22 years.

J Patient Rep Outcomes 2024; 8:37.

Abstract
BACKGROUND Goal attainment scaling (GAS), an established individualized, patient-centred outcome measure, is used to capture the patient's voice. Although first introduced ~60 years ago, there are few published guidelines for implementing GAS, and almost none for its use when caregivers GAS is implemented with caregiver input. We conducted a systematic review of studies that implemented GAS with caregiver input; and examined variations in GAS implementation, analysis, and reporting. METHODS Literature was retrieved from Medline, Embase, Cochrane, PsycInfo and CINAHL databases. We included randomized controlled trials (published between 1968 and November 2022) that used GAS as an outcome measure and involved caregiver input during goal setting. RESULTS Of the 2610 studies imported for screening, 21 met the inclusion criteria. Most studies employed GAS as a primary outcome. The majority (76%) had children as study participants. The most common disorders represented were cerebral palsy, developmental disorders, and dementia/Alzheimer's disease. The traditional five-point GAS scale, with levels from -2 to +2, was most often implemented, with -1 level typically being the baseline. However, most studies omitted essential GAS details from their reports including the number of goals set, number of attainment levels and whether any training was given to GAS facilitators. CONCLUSIONS GAS with caregiver input has been used in a limited number of randomized controlled trials, primarily in pediatric patients and adults with dementia. There is a variability in GAS implementation and many crucial details related to the specifics of GAS implementation are omitted from reports, which may limit reproducibility. Here we propose catalog that may be utilized when reporting research results pertaining to GAS with caregivers to enhance the application of this patient-centered outcome measure.

Abstract
Spasticity is a velocity-dependent increase in muscle tone that has a negative effect on quality of life and hinders the ability of others to provide care. In children, most cases are caused by cerebral palsy. Traditionally, many children are treated with surgery, sometimes performed before their limbs had grown sufficiently to permit long-term success. Nonsurgical treatment comprises oral pharmacological options, but their efficacy is limited and side effects such as drowsiness and decreased short-term memory are common; nerve block procedures can cause painful dysesthesias and muscle scarring. OnabotulinumtoxinA was first approved for the treatment of pediatric lower limb spasticity in Europe in the 1990s and is now licensed for use in pediatric patients in over 80 countries worldwide, based on a large body of clinical evidence demonstrating its efficacy and safety. In 2019 the U.S. Food and Drug Administration approved onabotulinumtoxinA for the treatment of pediatric patients with upper or lower limb spasticity. This approval represents 3 decades of work to refine the dose, measurements, patient selection, and muscle selection. The availability of onabotulinumtoxinA as a treatment for pediatric spasticity can have a substantial impact on a patient's quality of life. The use of onabotulinumtoxinA in combination with orthoses and occupational/physical therapy can postpone corrective surgery until growth is nearly complete and minimize the number of corrective surgeries.

Neutralizing Antibody Formation with OnabotulinumtoxinA (BOTOX ®) Treatment from Global Registration Studies across Multiple Indications: A Meta-Analysis. Toxins (Basel) 2023; 15:toxins15050342. [PMID: 37235376 DOI: 10.3390/toxins15050342] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2023] [Revised: 05/10/2023] [Accepted: 05/12/2023] [Indexed: 05/28/2023] Open
Abstract
Though the formation of neutralizing antibodies (NAbs) during treatment with botulinum neurotoxin is rare, their presence may nonetheless affect the biological activity of botulinum toxin and negatively impact clinical response. The goal of this updated meta-analysis was to evaluate and characterize the rate of NAb formation using an expanded dataset composed of 33 prospective placebo-controlled and open-label clinical trials with nearly 30,000 longitudinal subject records prior to and following onabotulinumtoxinA treatment in 10 therapeutic and aesthetic indications. Total onabotulinumtoxinA doses per treatment ranged from 10 U to 600 U administered in ≤15 treatment cycles. The NAb formation at baseline and post-treatment was tested and examined for impact on clinical safety and efficacy. Overall, 27 of the 5876 evaluable subjects (0.5%) developed NAbs after onabotulinumtoxinA treatment. At study exit, 16 of the 5876 subjects (0.3%) remained NAb positive. Due to the low incidence of NAb formation, no clear relationship was discernable between positive NAb results and gender, indication, dose level, dosing interval, treatment cycles, or the site of injection. Only five subjects who developed NAbs post-treatment were considered secondary nonresponders. Subjects who developed NAbs revealed no other evidence of immunological reactions or clinical disorders. This comprehensive meta-analysis confirms the low NAb formation rate following onabotulinumtoxinA treatment across multiple indications, and its limited clinical impact on treatment safety and efficacy.
