Background: We report the clinical outcomes observed in our patients with SMA type 1 or 2 receiving nusinersen, and we comment on the ethical implications of this treatment, in line with our results and those reported by Audic et al. in their analysis published in the Orphanet Journal of Rare Diseases. Methods: We analyzed records of all children with a genetically diagnosed SMA and clinically confirmed diagnosis of SMA Type 1 or 2 to whom nusinersen was offered. Follow-up lasted 30 months. Results: Among the 17 children with SMA type 1, 6 interrupted treatment with nusinersen due to adverse events or lack of efficacy. Of the remaining 11 patients, 9 are responding to therapy, though multidisciplinary complex care is still required. All those children started nusinersen at a very early age. Eighteen patients with SMA type 2 received nusinersen; five required treatment interruption. The other 13 patients are still on nusinersen therapy, and 6 are responders. Among the seven non-responders, only two met the inclusion criteria of the pivotal trial. Conclusions: Our analysis further supports the findings reported in the study by Audic et al. We believe that a wider use of nusinersen in clinical practice would require a comprehensive assessment of its actual benefits weighed against the discomfort caused to patients, as well as the identification of the patients who may obtain the best benefits from this treatment.
Background: Children with medical complexity (CMC) often require multiple medications, leading to polypharmacy, which seems to be linked to adverse effects, administration errors, and increased caregiver burden. This study aimed to describe the prevalence of polypharmacy, medication burden, off-label drug use, and associated costs. Methods: Conducted at the Pediatric Palliative Care Center of Padua, Italy, from August to October 2021, this cross-sectional observational study included patients up to 23 years old with at least one prescribed drug. Data were collected from medical records and caregiver interviews. Drug costs were collected from the Italian Medicine Agency. Descriptive statistical analysis was performed. For comparisons among categorical variables, the Chi-square test was used, and for those among continuous variables, the ANOVA test was used. Results: This study analyzed treatment regimens of 169 patients with a median age of 12.5 years (0.3–23). Polypharmacy was present in 52.7% of patients, and medication burden was observed in 44.4%, both varying significantly by primary diagnosis (p < 0.001). The median daily cost per patient was EUR 2.2 (IQR 0.9–7.1), with significant variation among subgroups. Only 34.6% of prescriptions were off-label. Conclusions: polypharmacy and medication burden are frequent among our CMC population, with some differences according to primary diagnosis.

Nusinersen is the first oligonucleotide-based drug that is approved for the treatment of spinal muscular atrophy. In January 2020, the WHO declared COVID-19 a pandemic and nusinersen-provider centers had to postpone planned infusions for some children along with other related interventions. Considering the important contribution that the intrathecal infusions and other support activities could have on the quality of life of spinal muscular atrophy patients and their families, this emergency could have a relevant impact on the course of the pathology. The present work aims to assess the clinical and social issues that arise for spinal muscular atrophy children in care at the referral pediatric palliative care Centre of Padua (Veneto) from a delay in nusinersen infusions, resulting from the contingent COVID-19 restrictions. This evaluation has been carried out in both the short and long term after the first lockdown period and can be considered as a “proxy” of a situation of a possible delay in administration or management of infusions, due to other different causes.
