    Hypoglycemia in Patients With LAMA2-CMD
    (2023) CAMELO, Clara Gontijo; MORENO, Cristiane de Araujo Martins; ARTILHEIRO, Mariana Cunha; SILVA, Andre Macedo Serafim; FONSECA, Alulin Tacio Quadros Monteiro; HOLANDA, Rodrigo Mendonca de; REED, Umbertina Conti; ZANOTELI, Edmar
    Background: Hypoglycemia has been reported in patients with LAMA2-CMD, but the frequency, risk factors, and correlation to genotype/phenotype have not been systematically assessed to date. Methods: A retrospective cohort study was performed on 48 patients with LAMA2-CMD. Patients were divided into two groups: a hypoglycemic group, with at least one episode of hypoglycemia, and a nonhypoglycemic group. The groups were compared according to gait function, epilepsy, intellectual disability, constipation, gastroesophageal reflux, gastrostomy, weight percentile, scoliosis, the use of a ventilator device, the use of a feeding device, neuromuscular disease swallowing status scale, and type of mutation. Results: Fifteen patients (31.2%) presented with at least one episode of symptomatic hypoglycemia and eight (16.6% of the cohort) had two or more episodes. All patients who had hypoglycemia were in the nonambulant group. We observed a correlation between gait, the use of ventilator and feeding devices, and swallow function with hypoglycemia. Patients with extremely low weight were five times more likely to have recurrent episodes of hypoglycemia. The presence of at least one missense variant appears to be associated with a lower risk of hypoglycemia. Conclusion: Patients with LAMA2-CMD are at risk of hypoglycemia. The risk is more relevant in patients with severe phenotype and patients with loss-of-function variants. For patients with extremely low weight, the risk is higher. Blood glucose should be actively measured in patients who are fasting or have infections, and health care providers should be prepared to identify and treat these patients.

    Muscle Ultrasound Changes Correlate With Functional Impairment in Spinal Muscular Atrophy
    (2023) MOREIRA, Ana Lucila; MENDONCA, Rodrigo Holanda; POLIDO, Graziela Jorge; OLIVEIRA, Marcos Castello Barbosa; SILVA, Andre Macedo Serafim; ZANOTELI, Edmar
    Objective: We investigated ultrasound patterns of muscle involvement in different types of spinal muscular atrophy (SMA) and their correlation with functional status to determine the pattern of muscle compromise in patients with SMA and the potential role of ultrasound to evaluate disease progression. Methods: We examined muscles (biceps brachii, rectus femoris, diaphragm, intercostals and thoracic multifidus) of 41 patients with SMA (types 1 to 4) and 46 healthy age-and sex-matched control individuals using B-mode ultra-sound for gray-scale analysis (GSA), area (biceps brachii and rectus femoris) and diaphragm thickening ratio. Functional scales were applied to patients only. We analyzed ultrasound abnormalities in specific clinical subtypes and correlated findings with functional status. Results: Compared with controls, patients had reduced muscle area and increased mean GSA for all muscles (p < 0.001), with an established correlation between the increase in GSA and the severity of SMA for biceps brachii, rectus femoris and intercostals (p = 0.03, 0.01 and 0.004 respectively) when using the Hammersmith Functional Motor Scale Expanded. Diaphragm thickening ratio was normal in the majority of patients, and intercostal muscles had higher GSA than diaphragm in relation to the controls. Conclusion: Ultrasound is useful for quantifying muscular changes in SMA and correlates with functional status. Diaphragm thickening ratio can be normal even with severe compromise of respiratory muscles in quantitative analysis, and intercostal muscles were more affected than diaphragm.
