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.

INTRODUCTION: The newborn screening (NBS) enables early diagnosis and treatment of several rare diseases (RD). Besides red reflex, hearing and pulse oximetry screening, the Brazilian NBS Program involves a blood spot test, including Phenylketonuria; Congenital hypothyroidism; Cystic fibrosis (CF); Congenital adrenal hyperplasia; Biotinidase deficiency and Sickle cell anemia. Given the limited epidemiological data on RD in Brazil, the Brazilian Rare Diseases Network (RARAS) was established aiming to perform a national survey on RD. OBJECTIVES: To analyze the epidemiological data of RD diagnosed through NBS in Brazil using data from the RARAS network. MATERIALS AND METHODS: Retrospective data of cases with confirmed or suspected RD diagnosis in the RARAS' centers between 2018-2019 were collected using RedCap. All cases diagnosed through NBS were included. RESULTS: Out of 12,530 RARAS records, 900 (7.18%) were diagnosed through NBS. Most were born in the Southeast region (42.38%), were female (66.56%) and admixed (50.59%). The mean age at data collection was 12.97 years (±10.54). Diagnosis was confirmed in 97.71% cases; 2.29% were under investigation. The Brazilian Unified Health System funded most diagnoses (98.27%). The most frequent diagnoses were Phenylketonuria (n=454); Congenital hypothyroidism (n=145) and CF (n=117). When excluding the pathologies from the public NBS Program, the most prevalent disorders were Maple syrup urine disease (n=15), Glucose-6-phosphate dehydrogenase deficiency and Galactosemia (n=5). Familial recurrence rate was 12.20% and consanguinity rate was 11.46%. Hospitalization was reported by 201 (22.89%), with a mean of 2.37 hospitalizations/participant, mainly due to CF. The mortality rate was 0.34%, with aminoacidopathies as the leading cause of death. CONCLUSIONS: The low mortality rate of this population compared to the Brazilian infant mortality rate in 2019 (1.33%), and the reduced hospitalization rate compared to the general RARAS' rate (4.12), underline the importance of early diagnosis through NBS for better outcomes. Furthermore, the higher consanguinity rate compared to the Brazilian (1.60%) and RARAS' rate (6.40%), may be due to the autosomal recessive inheritance of most screened diseases. Data show the importance of early diagnosis of life-threatening disorders that were not diagnosed in the public NBS, highlighting the necessity of expansion of screened disorders in this program.

Abstract Background: A rare disease is a medical condition with low prevalence in the general population, but these can collectively affect up to 10% of the population. Thus, rare diseases have a significant impact on the health care system, and health professionals must be familiar with their diagnosis, management, and treatment. Objective: This paper aims to provide health indicators regarding the rare diseases in Brazil and to create a network of reference centers with health professionals from different regions of the country. RARASnet proposes to map, analyze, and communicate all the data regarding the infrastructure of the centers and the patients' progress or needs. The focus of the proposed study is to provide all the technical infrastructure and analysis, following the World Health Organization and the Brazilian Ministry of Health guidelines. Methods: To build this digitized system, we will provide a security framework to assure the privacy and protection of each patient when collecting data. Systems development life cycle methodologies will also be applied to align software development, infrastructure operation, and quality assurance. After data collection of all information designed by the specialists, the computational analysis, modeling, and results will be communicated in scientific research papers and a digital health observatory. Results: The project has several activities, and it is in an initial stage. Initially, a survey was given to all health care centers to understand the technical aspects of each network member, such as the existence of computers, technical support staff, and digitized systems. In this survey, we detected that 59% (23/39) of participating health units have electronic medical records, while 41% (16/39) have paper records. Therefore, we will have different strategies to access the data from each center in the data collection phase. Later, we will standardize and analyze the clinical and epidemiological data and use these data to develop a national network for monitoring rare diseases and a digital health observatory to make the information available. The project had its financing approved in December 2019. Retrospective data collection started in October 2020, and we expect to finish in January 2021. During the third quarter of 2020, we enrolled 40 health institutions from all regions of Brazil. Conclusions: The nature of rare disease diagnosis is complex and diverse, and many problems will be faced in the evolution of the project. However, decisions based on data analysis are the best option for the improvement of the rare disease network in Brazil. The creation of RARASnet, along with all the digitized infrastructure, can improve the accessibility of information and standardization of rare diseases in the country.
