Management of Spinal Muscular Atrophy in the Adult Population.

Spinal muscular atrophy (SMA) is a group of neurodegenerative disorders resulting from the loss of spinal motor neurons. 95% of patients share a pathogenic mechanism of loss of survival motor neuron (SMN) 1 protein expression due to homozygous deletions or other mutations of the SMN1 gene, with the different phenotypes influenced by variable copy numbers of the SMN2 gene. Advances in supportive care, disease modifying treatment and novel gene therapies have led to an increase in the prevalence of SMA, with a third of SMA patients now represented by adults. Despite the growing number of adult patients, consensus on the management of SMA has focused primarily on the pediatric population. As the disease burden is vastly different in adult SMA, an approach to treatment must be tailored to their unique needs. This review will focus on the management of the adult SMA patient as they age and will discuss proper transition of care from a pediatric to adult center, including the need for continued monitoring for osteoporosis, scoliosis, malnutrition, and declining mobility and functioning. As in the pediatric population, multidisciplinary care remains the best approach to the management of adult SMA. Novel and emerging therapies such as nusinersen and risdiplam provide hope for these patients, though these medications are of uncertain efficacy in this population and require additional study.

'This battle, between your gut feeling and your mind. Try to find the right balance': Parental experiences of children with spinal muscular atrophy during COVID-19 pandemic.

AIMS: Parents of children with spinal muscular atrophy (SMA) often struggle with the all-consuming nature of the demands of caring for a child with substantial physical needs. Our aim was to explore experiences, challenges and needs of parents of a child with SMA in a COVID-19 pandemic situation. METHOD: Nineteen parents of 21 children (15 months to 13 years of age) with SMA types 1-3 participated in semi-structured interviews in June to July 2020. The interviews were analysed using inductive thematic analysis. RESULTS: Parents mentioned the protection of the health and well-being of the child as the central perspective and driving force during the COVID-19 pandemic. Three subthemes were identified: (1) responsibility, (2) balancing vulnerability and resilience and (3) (in)security. Some parents focused on the positive aspects during the lockdown, such as continuation of nusinersen treatment and family life. Some parents described helpful and positive cognitions to cope with the situation. In general, parents described a need for information with regard to COVID-19 and their child with SMA and a need for discussing their dilemmas and insecurities with a healthcare professional. INTERPRETATION: Parents put the health and well-being of their children first during the pandemic. From this study, we learned that parents of children with SMA need information and value direct contact with a healthcare professional to share their dilemmas and insecurities. The dialogue can help to empower parents in the conflicts and decisions they have to make during a pandemic.

Spinal muscular atrophy care in the COVID-19 pandemic era.

The coronavirus disease 2019 (COVID-19) pandemic has resulted in reorganization of healthcare settings affecting the delivery of clinical care to patients with spinal muscular atrophy (SMA). There is a concern that patients with SMA may be at increased risk of manifesting severe symptoms of COVID-19. Currently approved therapies for SMA improve survival and motor function; however, their delivery requires an increased exposure to the health system and a dedicated healthcare team. In this study, we discuss consensus recommendations pertaining to care of SMA patients during the pandemic. We highlight that SMA treatments should not be perceived as elective. Decisions regarding the delay of treatments should be made with consideration of the potential risks of COVID-19 exposure and the risk of that delay. We emphasize the importance of collaborative treatment decisions between the patient, family, and healthcare provider, considering any geographic- or institution-specific policies and precautions for COVID-19.
