O Hospital Universitário Bettina Ferro de Souza (HUBFS) oferece ensino, pesquisa e atendimento especializado gratuito em Oftalmologia, Otorrinolaringologia e Pediatria na Região Norte.
O Atlas Brasileiro Online de Doenças Raras é um serviço da Rede Nacional de Doenças Raras. Ele foi criado para disseminar informações sobre epidemiologia, quadro clínico, recursos diagnósticos e terapêuticos usados, e custos relacionados a doenças raras de origem genética e não genética no Brasil.
As doenças raras podem ser definidas como aquelas que afetam até 65 pessoas em cada 100 mil, ou seja, 1,3 pessoas para cada 2.000 indivíduos. No Brasil, estima-se que cerca de treze milhões de pessoas possuem alguma doença rara.
Após coletar, armazenar, processar e analisar os dados provenientes do projeto Rede Nacional de Doenças Raras, produzimos e publicamos estudos científicos para revistas e conferências científicas nacionais e internacionais.
Portanto, bem-vindo(a) a nossa lista de publicações. Essas publicações científicas representam um esforço contínuo para o entendimento e a explicação de fenômenos na área das doenças raras.
Esses esforços visam fornecer subsídios úteis e relevantes para a tomada de decisão baseadas em evidências no campo das doenças raras. Corroborando assim para o cumprimento dos objetivos gerais e específicos deste projeto.

The Brazilian Policy of Comprehensive Care for People with Rare Diseases (BPCCPRD) was established by the Ministry of Health to reduce morbidity and mortality and improve the quality of life of people with rare diseases (RD). Several laboratory tests, most using molecular genetic technologies, have been incorporated by the Brazilian Public Health System, and 18 specialised centres have so far been established at university hospitals (UH) in the capitals of the Southern, Southeastern and Northeastern regions. However, whether the available human and technological resources in these services are appropriate and sufficient to achieve the goals of care established by the BPCCPRD is unknown. Despite great advances in diagnosis, especially due to new technologies and the recent structuring of clinical assessment of RD in Brazil, epidemiological data are lacking and when available, restricted to specific disorders. This position paper summarises the performance of a nationally representative survey on epidemiology, clinical status, and diagnostic and therapeutic resources employed for individuals with genetic and non-genetic RD in Brazil. The Brazilian Rare Disease Network (BRDN) is under development, comprising 40 institutions, including 18 UH, 17 Rare Diseases Reference Services and five Newborn Screening Reference Services. A retrospective study will be initially conducted, followed by a prospective study. The data collection instrument will use a standard protocol with sociodemographic data and clinical and diagnostic aspects according to international ontology. This great collaborative network is the first initiative of a large epidemiological data collection of RD in Latin America, and the results will increase the knowledge of RD in Brazil and help health managers to improve national public policy on RD in Brazil.

INTRODUCTION: Phenylketonuria (PKU) is an inborn error of amino acid metabolism, with autosomal recessive inheritance. In non-treated patients, clinical signs may appear in the first months of life as hypotonia and neuropsychomotor development delay, in addition to seizures, irritability and a characteristic odor. In Brazil, PKU was one of the first genetic disorders to be included in neonatal screening, with the aim of starting early dietary treatment. OBJECTIVES: To present an overview of PKU in Brazil, using data from the Brazilian Rare Diseases Network (RARAS). MATERIALS AND METHODS: Data from individuals with a confirmed diagnosis of PKU assisted at the centers were included in this study. Cases were collected in the retrospective (2018-2019) and prospective (2022 to May 2024) survey. Data was collected and extracted from the REDCap. RESULTS: 717 individuals were included, 68.9% were female, with a mean age of 16.0 (±11.8) years at the time of data collection. Neonatal screening was responsible for 74.9% of diagnoses, while symptomatic diagnosis represented 22.5%. The largest paying source for diagnoses was the Unified Health System (SUS, 95.6%). The Southeast region had the highest number of diagnoses, with 65.2%, followed by the Northeast region, with 16.3%. CONCLUSION: Although included in neonatal screening since 2000, our data show that almost 1/4 of patients (22.5%) were diagnosed after presenting symptoms. Although the largest source of payment for diagnoses is the SUS, there is great regional inequality. Furthermore, this study corroborates the importance of diagnosis in the neonatal period to begin treatment in the first days of life. The majority of diagnoses in this registry were made through the Brazilian Unified Health System (SUS), highlighting the crucial role of the public healthcare system in neonatal screening and the diagnosis of rare diseases.
