RESUMO
OBJECTIVE: To evaluate the effects of nusinersen on respiratory function of patients with type 1 spinal muscular atrophy. STUDY DESIGN: Observational, longitudinal cohort study. We collected respiratory data from 118 children with type 1 spinal muscular atrophy and differing pulmonary requirements and conducted a semistructured qualitative interview among a subsample of caregivers at baseline, 6 months, and 10 months after the first nusinersen treatment. Patients were stratified according to ventilation modalities and age at study entry. RESULTS: Most patients in our cohort remained stable (84/109 = 77%). More than 80% of the children treated before age 2 years survived, in contrast to the lower survival reported in natural history studies, and did so without tracheostomy or noninvasive ventilation (NIV) ≥16 hours. In those less than 2 years old, only 3 patients shifted from NIV ≤10 hours to NIV >10 hours, and the other 3 reduced the hours of NIV required. Most of the older patients remained stable; this included not only those on tracheostomy or NIV >10 hours but also 75% of those on NIV ≤10 hours. CONCLUSIONS: Our results suggest that nusinersen may produce some improvement in the progression of respiratory impairment, both in terms of survival and need for respiratory support ≥16 hours, especially before the age of 2 years.

Chronic spontaneous urticaria (CSU), defined as the occurrence of spontaneous wheals for more than six weeks, has been associated with autoimmune diseases. Herein, we report the unusual association of CSU, Graves' disease, and premature ovarian failure. Human leukocyte antigen (HLA) studies were performed. A 36-year-old woman presented symptoms and signs of hyperthyroidism for three months. In the same period, the patient complained of widespread urticarial wheals, intensely itchy, and poorly responsive to therapy with antihistaminic agents. Hyperthyroidism was confirmed biochemically, and treatment with methimazole was started. As hyperthyroidism improved, a marked improvement in her urticaria was also observed. However, the patient continued to complain of amenorrhea. Endocrine evaluation, at the age 38, was consistent with premature ovarian failure. This is the first report of coexistence of GD, CSU, and POF. The genetic background of such unusual association is a specific combination of HLA.
A urticária crônica idiopática, caracterizada pelo aparecimento de pápulas espontâneas e persistentes por pelo menos seis semanas, tem sido associada a doenças autoimunes. Apresentamos aqui o caso da associação incomum entre urticária crônica idiopática, doença de Graves e falência ovariana prematura. Foram conduzidos estudos de tipagem HLA. Uma mulher de 36 anos apresentou sinais e sintomas de hipertireoidismo por três meses. No mesmo período, a paciente queixou-se do aparecimento de pápulas urticariformes generalizadas que coçavam intensamente e não eram responsivas ao tratamento com anti-histamínicos. O hipertireoidismo foi confirmado bioquimicamente, e o tratamento com metimazol foi iniciado. Assim que os valores hormonais se normalizaram, observou-se uma melhoria significativa do quadro de urticária. No entanto, a paciente continuou a apresentar amenorreia. A avaliação endocrinológica, com a idade de 38 anos, mostrou falência ovariana prematura. Este é o primeiro caso de associação entre doença de Graves, urticária idiopática crônica e falência ovariana prematura. A base genética dessa associação incomum é representada por combinações específicas de haplótipos HLA.
