- Effect of the COVID-19 pandemic on patients with inherited neuromuscular disorders(2022) MORENO, Cristiane Araujo Martins; CAMELO, Clara Gontijo; SAMPAIO, Pedro Henrique Marte de Arruda; FONSECA, Alulin Tacio Quadros Santos Monteiro; ESTEPHAN, Eduardo de Paula; SILVA, Andre Macedo Serafim; PIROLA, Renann Nunes; SILVA, Luiz Henrique Libardi; LIMA, Karlla Danielle Ferreira; ALBUQUERQUE, Marco Antonio Veloso de; CAMELO FILHO, Antonio Edvan; MARQUES, Marcos Vinicius Oliveira; YANAGIURA, Mario Teruo; CAVALCANTE, Wagner Cid Palmeira; MATSUI JUNIOR, Ciro; ISIHI, Lucas Michielon de Augusto; MENDONCA, Rodrigo Holanda; POUZA, Ana Flavia Pincerno; CARVALHO, Mary Souza de; REED, Umbertina Conti; ZANOTELI, EdmarBackground: The COVID-19 pandemic has brought substantial challenges for current practices in treating hereditary neuromuscular disorders (hNMDs). However, this infection has not been the only concern for these patients. Social distancing has compromised multidisciplinary assistance and physical activity, and has brought about several mental health issues. We presented a follow-up on 363 patients with hNMDs at a Brazilian tertiary center during the peak of the COVID-19 pandemic. Objective: We aimed to show the frequency and severity of SARS-CoV-2 infection among hNMD patients and to demonstrate the effects of the pandemic on life habits, disease progression and multidisciplinary supportive care status. Methods:Three hundred and sixty-three patients (58% male and 42% female) were followed for three months through three teleconsultations during the peak of the COVID-19 pandemic in Brazil. Results: There were decreases in the numbers of patients who underwent physical, respiratory and speech therapies. For several patients, their appetite (33%) and sleep habits (25%) changed. Physical exercises and therapies were interrupted for most of the patients. They reported new onset/worsening of fatigue (17%), pain (17%), contractions (14%) and scoliosis (7%). Irritability and sleep, weight and appetite changes, and especially diminished appetite and weight loss, were more frequent in the group that reported disease worsening. There was a low COVID-19 contamination rate (0.8%), and all infected patients had a mild presentation. Conclusion: The isolation by itself was protective from a COVID-19 infection perspective. However, this isolation might also trigger a complex scenario with life habit changes that are associated with an unfavorable course for the NMD.
- Guillain-Barre syndrome spectrum as manifestation of HIV-related immune reconstitution inflammatory syndrome: case report and literature review(2022) VIDAL, Jose E.; GUEDES, Bruno F.; GOMES, Helio R.; MENDONCA, Rodrigo HolandaA 34-year-old man presented with a history of 21-days of gait unsteadiness and diplopia. Ten days before presentation, he developed limb weakness and in the last three days reduced consciousness. HIV infection was diagnosed three months ago (CD4+ = 160 cells/ mm(3); viral load HIV-1 = 144.000 copies/mL), and antiretroviral therapy was initiated. Impaired consciousness, ophthalmoplegia, limb weakness, ataxia, areflexia, and Babinsky's sign were noted. At that moment, CD4+ count was 372 cells/mm 3 and viral load HIV-1 <50 copies/mL. The clinical, laboratory and neurophysiological findings suggest overlapping Guillain-Barre syndrome (GBS) and Bickerstaff brainstem encephalitis as manifestation of HIV-related immune reconstitution inflammatory syndrome (IRIS). Here, we review and discuss 7 cases (including the present report) of GBS spectrum as manifestation of HIV-related IRIS. (C) 2022 Sociedade Brasileira de Infectologia.
- Gene therapy in neuromuscular disorders(2022) MENDONCA, Rodrigo Holondo; ZANOTELI, EdmorMonogenic neuromuscular disorders are potentially treatable through gene therapy. Using viral vectors, a therapeutic transgene aims to restore normal levels of a protein not produced by the defective gene, or to silence a gene whose expression leads to toxic effects. Spinal Muscular Atrophy (SMA) is a good example of a monogenic disease that currently has an AAV9-based vector gene therapy as a therapeutic option. In this review, we intend to discuss the viral vectors and their mechanisms of action, in addition to reviewing the clinical trials that supported the approval of gene therapy (AVXS-101) for SMA as well as neuromuscular diseases that are potentially treatable with gene replacement therapy.
- The Location of Disease-Causing DES Variants Determines the Severity of Phenotype and the Morphology of Sarcoplasmic Aggregates(2022) SILVA, Andre Macedo Serafim; RODRIGO, Patricia; MORENO, Cristiane Araujo Martins; MENDONCA, Rodrigo de Holanda; ESTEPHAN, Eduardo de Paula; CAMELO, Clara Gontijo; CAMPOS, Eliene Dutra; DIAS, Alexandre Torchio; NASCIMENTO, Amom Mendes; KULIKOWSKI, Leslie Domenici; OLIVEIRA, Acary Souza Bulle; REED, Umbertina Conti; GOLDFARB, Lev G.; OLIVE, Montse; ZANOTELI, EdmarDesmin (DES) is the main intermediate muscle filament that connects myofibrils individually and with the nucleus, sarcolemma, and organelles. Pathogenic variants of DES cause desminopathy, a disorder affecting the heart and skeletal muscles. We aimed to analyze the clinical features, morphology, and distribution of desmin aggregates in skeletal muscle biopsies of patients with desminopathy and to correlate these findings with the type and location of disease-causing DES variants. This retrospective study included 30 patients from 20 families with molecularly confirmed desminopathy from 2 neuromuscular referral centers. We identified 2 distinct patterns of desmin aggregates: well-demarcated subsarcolemmal aggregates and diffuse aggregates with poorly delimited borders. Pathogenic variants located in the 1B segment and the tail domain of the desmin molecule are more likely to present with early-onset cardiomyopathy compared to patients with variants in other segments. All patients with mutations in the 1B segment had well-demarcated subsarcolemmal aggregates, but none of the patients with variants in other desmin segments showed such histological features. We suggest that variants located in the 1B segment lead to well-shaped subsarcolemmal desmin aggregation and cause disease with more frequent cardiac manifestations. These findings will facilitate early identification of patients with potentially severe cardiac syndromes.
