- Congenital fiber type disproportion caused by TPM3 mutation: A report of two atypical cases(2020) MORENO, Cristiane Araujo Martins; ESTEPHAN, Eduardo de Paula; FAPPI, Alan; MONGES, Soledad; LUBIENIECKI, Fabiana; ABATH NETO, Osorio Lopes; REED, Umbertina Conti; DONKERVOORT, Sandra; HARMS, Matthew B.; BONNEMANN, Carsten; ZANOTELI, EdmarCongenital fiber type disproportion (CFTD) is a rare congenital myopathy subtype defined by slow type 1 hypotrophy in the absence of any other major structural findings such as rods, central nuclei or cores. Dominant missense changes in slow alpha-tropomyosin coded by TPM3 gene are the main cause of the CFTD. There are only a few reports of recessive loss-of-function mutations in TPM3 causing severe Nemaline Myopathy and CFTD. We present two patients harboring TPM3 mutations. The first is a novel homozygous missense variant with a mild CFTD clinical phenotype inherited in a recessive fashion. The second is a previously reported heterozygous mutation presenting within pronounced early axial involvement and dropped head. This report expands the genotype-phenotype correlation in the TPM3 myopathy showing a recessive mutation causing a mild clinical phenotype and also shows that TPM3 mutations should be part of the investigation in patients with dropped head.
- Myasthenia Gravis Related to Thymic Carcinoma: A Case Study(2020) LOPES, Daniel Thomas Pereira; GOMES, Samila Marissa Pinheiro; SIQUEIRA, Sheila Aparecida Coelho; FRASSETTO, Fernando Pereira; SAMPAIO, Pedro Henrique Martins Arruda; MORENO, Cristiane Araujo Martins; ROCHA, Maria Sheila Guimaraes; ESTEPHAN, Eduardo PaulaMyasthenia gravis and thymoma are often presented in association with similar to 10% of myasthenic cases having concomitant thymoma. Thymic carcinoma is one of the rarest/aggressive human epithelial tumors and has no correlation with myasthenia gravis hitherto. Here is provided a clinical case and review of literature on a very rare association of thymic carcinoma (with no sign of thymoma) and myasthenia gravis (antiacetylcholine receptor antibody positive). Two years after thymectomy, clinical evolution was satisfactory. This clinical case elicits hypothesis that thymic carcinoma may be related with myasthenia gravis, what may have good prognostic from oncologic and neurologic perspectives.
- 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.
- 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.
- Clinical variability of early-onset congenital myasthenic syndrome due to biallelic RAPSN mutations in Brazil(2018) ESTEPHAN, Eduardo de Paula; ZAMBON, Antonio Alberto; MARCHIORI, Paulo Euripedes; SILVA, Andre Macedo Serafim da; CALDAS, Vitor Marques; MORENO, Cristiane Araujo Martins; REED, Umbertina Conti; HORVATH, Rita; TOPF, Ana; LOCHMUELLER, Hanns; ZANOTELI, EdmarMutations in RAPSN are an important cause of congenital myasthenic syndrome (CMS), leading to endplate acetylcholine receptor deficiency. We present three RAPSN earlyonset CMS patients (from a Brazilian cohort of 61 CMS patients). Patient 1 and patient 2 harbor the mutation p.N88K in homozygosity, while patient 3 harbors p.N88K in compound heterozygosity with another pathogenic variant (p.V165M; c.493G > A). At onset, patient 3 presented with more severe symptoms compared to the other two, showing generalized weakness and repeated episodes of respiratory failure in the first years of life. During adolescence, she became gradually less symptomatic and does not require medication anymore, presenting better long-term outcomes than patients 1 and 2. This case series illustrates the variability of RAPSN earlyonset CMS, with patient 3, despite severe onset, revealing an almost complete reversal of myasthenic symptoms, not limited to apneic episodes. Moreover, it suggests that RAPSN CMS may be underdiagnosed in nonEuropean countries.
