Paciente varón de tres años con sibilancias y tos crónica / Three-Year-Old Male with Wheezing and Chronic Cough

Se presenta el caso de un niño de 3 años con diagnóstico de asma, rinitis alérgica, características craneofaciales dismórficas e infecciones respiratorias altas y bajas recurrentes, manejado como asma desde un inicio. Como parte del estudio de comorbilidades, se decide realizar una prueba del sudor que sale en rango intermedio y más tarde se encuentra una mutación, donde se obtiene un resultado positivo para una copia que se asocia a fibrosis quística. Se revisará el caso, así como el diagnóstico, clínica y tratamiento del síndrome metabólico relacionado con el regulador de conductancia transmembrana de fibrosis quística (CRMS).

We present the case of a 3-year-old boy with a diagnosis of asthma, allergic rhinitis, dysmorphic craniofacial characteristics and recurrent upper and lower respiratory infections, managed as asthma from the beginning. As part of the study of comorbidi-ties, it was decided to carry out a sweat test that came out in the intermediate range and later one mutation was found, where a positive result was obtained for a copy that is associated with cystic fibrosis. The case will be reviewed, as well as the diagnosis, symptoms and treatment of the metabolic syndrome related to the cystic fibrosis trans-membrane conductance regulator (CRMS).

Cystic fibrosis: when neonatal screening is unsatisfactory for early diagnosis / Fibrose cística: quando a triagem neonatal é insatisfatória para o diagnóstico precoce

Abstract Introduction: cystic fibrosis newborn screening must enable its earlier diagnosis, which may enhance outcomes. This study was a series case of delayed-diagnosis children submitted to cystic fibrosis newborn screening. Description: fourteen children were included; eight (57.1%) were due to false-negative screening, while six (42.9%) were due to processing errors. Two samples collected after 30 days of life were incorrectly classified as negative, and four infants with a positive test could not be located due to screening processing errors. Cystic fibrosis diagnosis was confirmed at a median (IQR) age of 5.3 (4.2-7.4) months. Poor nutritional status was the most prevalent clinical sign at diagnosis, being present in 78.6% of infants. The mean (SD) weight-for-length and length-for-age Z-scores were -3.46 (0.84) and -3.99 (1.16), respectively. Half of the children had Pseudo-Bartter syndrome, and 42.9% had breathing difficulties. Twelve children (85.7%) required hospitalization, with a median (IQR) length of stay of 17.0 (11.5-26.5) days. Discussion: newborn screening had some faults, from incorrect collections to inefficient active search. Early identification of these children in which screening was unsatisfactory is essential, emphasizing the importance and efforts to not miss them. In the case of a failed test, healthcare professionals must be prepared to recognize the main symptoms and signs of the disease.

Resumo Introdução: a triagem neonatal para fibrose cística deve contribuir para diagnóstico precoce e melhor prognóstico da doença. O estudo é uma série de casos com lactentes submetidos à triagem, porém com diagnóstico tardio da doença. Descrição: quatorze crianças foram incluídas; oito (57,1%) com triagem falso-negativo e seis (42,9%) com erros processuais na triagem neonatal. Duas amostras foram coletadas tardiamente, sendo incorretamente classificadas como negativas e quatro lactentes com triagem positiva não foram localizados, por erros na busca ativa. Confirmou-se o diagnóstico da fibrose cística com idade mediana (IIQ) de 5,3 (4,2-7,4) meses. O Comprometimento nutricional precoce foi o sinal clínico mais prevalente ao diagnóstico, presente em 78,6% das crianças. Os Z escores médios (SD) do peso para altura e altura para idade foram -3,46 (0,84) e -3,99 (1,16), respectivamente. Metade das crianças teve síndrome de Pseudo-Bartter e 42,9% dificuldade respiratória. Doze crianças (85,7%) precisaram hospitalização com tempo mediano de permanência de 17 dias. Discussão: a triagem neonatal para fibrose cística apresentou falhas, desde testes falso-negativos, coletas incorretas, até problemas com a busca ativa. Entretanto, o diagnóstico ágil é essencial e os profissionais de saúde devem reconhecer os sintomas e sinais precoces da doença, mesmo quando a triagem neonatal não for satisfatória.

Introduction: Based on the need for audiological diagnosis and intervention as soon as possible in the life of a child with hearing loss, it is necessary to elaborate of hearing evaluation protocols with high efficiency, which provide the greatest amount of information. Aim: To analyze a pediatric hearing health program regarding their adherence to hearing screening, failure rates, and diagnostic procedures. Method: This is a cross-sectional, descriptive, quantitative study, and consisted of tree stages: Performed in three steps: 1st step: hearing screening of rooming-in neonates; 2nd stage: retest of failures; 3rd stage: audiological diagnosis of infants who failed in the previous stages using the Steady State Response (ASSR) together with the Brainstem Evoked Response Audiometry (BERA). Results: In 2019, 1,898 infants were submitted to the program, of whom 287 (15.2%) failed the screening in at least one of the ears. A total of 197 (10.3%) infants attended the retest and 14 (0.73%) failed the TOAE in at least one of the ears. Ten (0.52%) infants returned for diagnosis. The sample was homogeneously full-term children. One child showed unilateral HL. The average amount of time required to collect information in the ASSR was 20 minutes. Conclusion: For diagnosis, ASSR can be an alternative to be used in the battery of examinations in pediatric hearing assessment along with the other procedures, using the cross-check principle and adding valuable information, especially regarding the low frequencies.

En este sentido, se ha tomado a bien, ampliar el tamizaje metabólico neonatal para incluir la detección de los errores congénitos del metabolismo más frecuentes como son: hipotiroidismo congénito, fibrosis quística, fenilcetonuria, tirosinemia neonatal transitoria, enfermedad de jarabe de arce e hiperplasia suprarrenal congénita. Por lo anterior, los presentes lineamientos técnicos de tamizaje metabólico neonatal, describen las disposiciones para realizar la toma de muestra para la detección, confirmación diagnóstica, tratamiento oportuno, seguimiento, monitoreo y evaluación en los establecimientos del Sistema Nacional Integrado de Salud (SNIS)

The Ministry of Health, in the context of the National Early Childhood Development Support Policy "Growing Together" and in line with the recent Birth with Affection Act for Respected Childbirth and Caring and Sensitive Care for the Newborn, from the Office of the First Lady, decides to implement strategies to reduce morbidity and mortality, including addressing those situations or conditions that affect neurodevelopment in children. In this sense, we have taken good care to expand the neonatal metabolic screening to include the detection of the most frequent congenital errors of metabolism such as: congenital hypothyroidism, cystic fibrosis, phenylketonuria, transient neonatal tyrosinemia, maple syrup disease and congenital adrenal hyperplasia. Therefore, the present technical guidelines for neonatal metabolic screening describe the arrangements for sampling for detection, diagnostic confirmation, timely treatment, monitoring, monitoring and evaluation in the National Integrated Health System

Determinación de valores de corte de 17 hidroxiprogesterona ajustados por edad gestacional para la pesquisa neonatal de la hiperplasia suprarrenal congénita / Assessment of gestational age-adjusted 17-hydroxyprogesterone cut-off values for neonatal screening of congenital adrenal hyperplasia

La pesquisa neonatal de hiperplasia suprarrenal congénita se realiza mediante la determinación de 17 hidroxiprogesterona (17OHP) en gotas de sangre seca en papel de filtro. Los bebés prematuros presentan valores más elevados que los bebés de término, siendo de utilidad contar con límites de corte apropiados. Nuestro objetivo fue actualizar los valores de corte de 17OHP ajustados por edad gestacional para la metodología en uso a nivel nacional por las jurisdicciones asistidas por el "Programa Nacional de Fortalecimiento de la Detección Precoz de Enfermedades Congénitas". La 17OHP se determinó utilizando el kit comercial de enzimo-inmunoanálisis (ELISA competitivo), Elizen Neonatal 17OHP Screening (Zentech, Bélgica). Se obtuvieron límites de corte utilizando percentiles de la distribución de los valores de 17OHP para cada edad gestacional. La sensibilidad obtenida fue 100%, especificidad 98,76 %, tasa de falsos positivos 1,24 % y el valor predictivo positivo 1,12 %. Destacamos la importancia de disponer de límites de corte adecuados a la población. La armonización de los mismos permitirá resultados comparables entre los programas regionales de pesquisa neonatal (AU)

Newborn screening for congenital adrenal hyperplasia is performed by the measurement of 17-hydroxyprogesterone (17OHP) in dried blood spots on filter paper. Premature infants have higher values than full-term infants, and appropriate cutoff values are useful. Our aim was to update the cut-off values of 17OHP adjusted for gestational age for the methodology used at a national level in regions assisted by the "National Program for Strengthening the Early Detection of Congenital Diseases". 17OHP was determined using the commercial enzyme-linked immunosorbent assay (competitive ELISA) kit, Elizen Newborn 17OHP Screening (Zentech, Belgium). Cut-off values were obtained using percentiles of the distribution of 17OHP values for each gestational age. Sensitivity was 100%, specificity 98.76%, false positive rate 1.24%, and positive predictive value 1.12%. It is important to have cut-off values that are adjusted to the population. Harmonization will allow for the comparison of results among regional newborn screening programs (AU)

Access to pediatric hearing healthcare in Rio Grande do Norte, Brazil / Acesso ao serviço de saúde auditiva infantil no Rio Grande do Norte, Brasil

INTRODUCTION: Hearing impairment compromises the child's language development and learning process. Neonatal screening, diagnosis, and hearing intervention are actions that must be carried out for comprehensive hearing healthcare in childhood. OBJECTIVE: To assess access to children's hearing healthcare services and the factors that influence access. METHODS: Cross-sectional study with 104 children who underwent neonatal hearing screening and were referred for diagnosis. The sources were the databases, where demographic, social, and variables related to the access and use of health services were collected. Percentage distribution of categorical variables and measures of central tendency and dispersion of continuous variables were performed. To assess the association of dependent and independent variables, the Chi-square test was used with a 5% significance level. RESULTS: Only 56 (53.3%) of screened children attended hearing healthcare services. Of these, 41 went to the studied service, and 24 completed the diagnosis. Three children had hearing loss and were candidates for cochlear implants. The mean age at diagnosis was 211 days and the standard deviation was 155.9 days. The duration of diagnosis was 135 days and the standard deviation was 143.2 days. There was no statistical significance between access to health services and the distance of the service, age, and education of the mother. CONCLUSION: There is a lack of access to the service and completion of the diagnosis and children are not assisted at appropriate ages. The mother's age and education and distance to the service did not influence access to and use of the service.

INTRODUÇÃO: A deficiência auditiva compromete o desenvolvimento da linguagem e o processo de aprendizagem na criança.

Introducción: La hipoacusia congénita es una patología frecuente entre los recién nacidos con gran impacto en su calidad de vida si no es diagnosticada y tratada precozmente. Para su pesquisa, se recomienda, internacionalmente, el tamizaje auditivo universal neonatal (TAUN), que desde 2014 se aplica en el Hospital Clínico La Florida Dra. Eloísa Díaz Insunza (HLF). Objetivo: Describir la experiencia del programa de TAUN del Servicio de Otorrinolaringología HLF. Material y Método: Estudio descriptivo, retrospectivo. Se incluyó a todos los recién nacidos vivos (RNV) del establecimiento entre 2015 y 2021, evaluados de acuerdo con el protocolo del programa. Resultados: Fueron evaluados 17.804 RNV. Se obtuvo una cobertura de 97,1% y tasa de referencia de 0,98%. Se confirmaron a 21 pacientes con hipoacusia sensorioneural (HSN), obteniéndose una tasa de HSN de 1,5 cada 1.000 RNV. Conclusión: La tasa de incidencia de HSN congénita fue similar a la estimada a nivel mundial. El programa de TAUN HLF cumple con estándares internacionales en cuanto a cobertura, tiempo de evaluación del tamizaje y tasa de referencia. El trabajo multidisciplinario, mejoría de tecnología y registro adecuado de pacientes, son las principales fortalezas. La dificultad de seguimiento durante horario inhábil y presencia de sólo un profesional con dedicación exclusiva, son aspectos a perfeccionar.

Introduction: Congenital hearing loss is a frequent pathology among newborns with great impact on their quality of life if it is not diagnosed and treated early. The Joint Committee on Infant Hearing recommends universal newborn hearing screening (UNHS) and has been applied at the Hospital Clínico La Florida Dra. Eloísa Díaz Insunza (HLF) since 2014. Aim: To describe the experience of UNHS program at the Otolaryngology Service of the HLF. Material and Method: Descriptive, retrospective study, including all newborns of the HLF between 2015 and 2021. They were evaluated according to the protocol proposed in the program. Results: 17804 newborns were evaluated. Coverage of 97,1% and a referral rate of 0,98% were obtained. Twenty-one patients with sensorineural hearing loss (SNHL) were confirmed, obtaining a SNHL rate of 1.5 per 1000 live births. Conclusion: The incidence rate of congenital SNHL is similar to that estimated worldwide. The UNHS program in HLF complies with international standards in terms of coverage, timing and referral rates. Multidisciplinary work, improved technology and adequate patient registration are the main strengths of the program. The difficulty of follow-ups during the weekends and the presence of only one full-time professional are aspects that can be improved.

Diagnóstico audiológico de lactentes após falha na triagem auditiva neonatal universal / Hearing assessment after referral in universal newborn hearing screening

RESUMO Objetivo Estudar o processo de diagnóstico audiológico de lactentes que falharam na Triagem Auditiva Neonatal Universal (TANU). Métodos Análise dos prontuários de 51 lactentes que falharam na TANU nas maternidades do munícipio e que foram encaminhados a um centro de referência em saúde auditiva para diagnóstico audiológico, entre janeiro e junho de 2021. Foram identificados os lactentes que finalizaram o diagnóstico, aqueles que não compareceram ao agendamento para exames ou evadiram durante o processo. Tentativas de contato foram realizadas com os responsáveis pelos lactentes que evadiram, para identificar o motivo da evasão. Resultados O comparecimento ao diagnóstico ficou em 75%, com evasões entre o encaminhamento da maternidade para o centro de referência, bem como durante o processo de diagnóstico. Cinquenta por cento dos sujeitos concluíram as avaliações audiológicas até os 3 meses de vida. A tentativa de contato foi bem-sucedida com os responsáveis pelos lactentes que evadiram, sendo os motivos mais frequentes: adoecimento do lactente, distância entre a moradia e o centro de referência, horário de trabalho dos pais. Conclusão Na etapa de diagnóstico, o índice de comparecimento e o tempo de conclusão até o terceiro mês de vida da criança ficaram abaixo dos índices recomendados, diminuindo a efetividade do Programa de Triagem Auditiva Neonatal Universal (PTANU). A busca ativa por contato telefônico e uso de aplicativo de mensagem telefônico foi importante para reduzir a evasão em 76%. Outras ferramentas que aprimorem o processo para um diagnóstico não prolongado, evitando evasões, necessitam ser estudadas.

ABSTRACT Purpose To study the process of hearing assessment in infants who were referred by professionals responsible for Universal Newborn Hearing Screening (UNHS). Methods Analysis of the medical records of 51 infants referred by maternity hospitals where UNHS was performed and were referred to a Hearing Health Center, between January and June 2021. Infants who completed hearing assessment, who never attended the appointments, or were lost during the diagnostic process were identified. Attempts were made to contact infants' guardians in order to understand the reason for missing the appointments. Results The attendance to the diagnosis was 75%. Fifty percent of the infants completed hearing assessment as recommended, up to 3 months of life. The attempt to contact parents who missed the appointments was successful, and the most frequent reasons are: the infant was ill on the day of scheduled appointment, distance from home to the hearing health center, parents' working hours. Conclusion For the diagnostic stage, the attendance rate and the age for completing hearing assessment were below the recommended. The active search for telephone contact and use of phone messaging application was important to reduce evasion by seventy-six percent. Tools that optimize the diagnostic process with less infants missing still must be studied.

Newborn Screening Center Mindanao census from 2019 to 2022

@#Congenital disorders cause a global estimate of 240,000 deaths in newborns and 170,000 deaths in children ages 1 month up to 5 years every year. 1 In order to detect metabolic, hematologic, or endocrine disorders in newborns, newborn screening (NBS) is conducted in many countries around the world. In the Philippines, NBS was introduced by the Newborn Screening Study Group in 1996, with the aim of establishing the incidence of six metabolic conditions, namely, congenital hypothyroidism, congenital adrenal hyperplasia, galactosemia, phenylketonuria, homocystinuria, and glucose-6-phosphate dehydrogenase deficiency, and creating recommendations for the adoption of NBS nationwide.2 The Republic Act No. 9288, otherwise known as the Newborn Screening Act of 2004, requires that the Department of Health shall ensure the establishment and accreditation of newborn screening centers (NSCs) in strategically located areas across the Philippines.3 At present, there are seven operational NSCs in the country,4 with the Newborn Screening Center-Mindanao (NSC-Mindanao) in Southern Philippines Medical Center (SPMC) as the only center catering to all NBS facilities all over Mindanao.5 NSC-Mindanao initially performed screening tests for five disorders, but now tests for a panel of 29 metabolic and other congenital disorders.

Acceptance, knowledge, and experiences of Pediatric Hematologists in the Philippines on newborn screening for hemoglobinopathies

Background@#Hemoglobinopathies as a group is one of the most common conditions confirmed through the newborn screening (NBS) program of the Philippines. This led to the increased participation of pediatric hematologists in the NBS program.@*Objective@#The aim of the study was to assess newborn screening acceptance and knowledge of pediatric hematologists using an online questionnaire.@*Method@#Members of the Philippine Society of Pediatric Hematology (PSPH), who are practicing pediatric hematologists in the Philippines, were invited to answer an online questionnaire.@*Results@#Sixty members of the PSPH (65.2%) answered the survey. All the respondents are familiar with the newborn screening program. Fifty-seven respondents (95 %) have already managed a case of hemoglobinopathy identified through the newborn screening program. Differences in the approach to management and level of confidence with diagnostic test result interpretation have been noted. General themes of their concerns include being unaware of the protocol, concerns on delays in confirmatory tests, request for guidelines on follow-up, and incongruence of results with clinical picture.@*Conclusion@#The information collected may be used to develop strategies to better equip our pediatric hematologists and assist the PSPH standardize management protocols for hemoglobinopathies.

Pilot implementation of a community-based, eHealth-enabled service delivery model for newborn hearing screening and intervention in the Philippines

Objectives@#This study explores the potential of the HeLe Service Delivery Model, a community-based newborn hearing screening (NHS) program supported by a web-based referral system, in improving provision of hearing care services. @*Methods@#This prospective observational study evaluated the HeLe Service Delivery Model based on records review and user perspectives. We collected system usage logs from July to October 2018 and data on patient outcomes. Semi-structured interviews and review of field reports were conducted to identify implementation challenges and facilitating factors. Descriptive statistics and content analysis were used to analyze quantitative and qualitative data, respectively. @*Results@#Six hundred ninety-two (692) babies were screened: 110 in the RHUs and 582 in the Category A NHS hospital. Mean age at screening was 1.4±1.05 months for those screened in the RHU and 0.46±0.74 month for those in the Category A site. 47.3% of babies screened at the RHU were ≤1 month old in contrast to 86.6% in the Category A hospital. A total of 10 babies (1.4%) received a positive NHS result. Eight of these ten patients were referred via the NHS Appointment and Referral System; seven were confirmed to have bilateral profound hearing loss, while one patient missed his confirmatory testing appointment. The average wait time between screening and confirmatory testing was 17.1±14.5 days. Facilitating factors for NHS implementation include the presence of champions, early technology adopters, legislations, and capacity-building programs. Challenges identified include perceived inconvenience in using information systems, cost concerns for the patients, costly hearing screening equipment, and unstable internet connectivity. The lack of nearby facilities providing NHS diagnostic and intervention services remains a major block in ensuring early diagnosis and management of hearing loss in the community. @*Conclusion@#The eHealth-enabled HeLe Service Delivery Model for NHS is promising. It addresses the challenges and needs of community-based NHS by establishing a healthcare provider network for NHS in the locale, providing a capacity-building program to train NHS screeners, and deploying health information systems that allows for documentation, web-based referral and tracking of NHS patients. The model has the potential to be implemented on a larger scale — a deliberate step towards universal hearing health for all Filipinos.

Implementation of Universal Newborn Hearing Screening in the Philippines: A survey of registered newborn hearing centers

Background@#Universal newborn hearing screening is mandated in the Philippines through the Universal Newborn Hearing Screening and Intervention Act of 2009 (RA 9709). Newborn hearing screening (NBHS) centers are required to perform screening tests, compile and submit data on screened newborns, and advise parents on the subsequent steps after NBHS.@*Objective@#The study aimed to conduct a survey of the implementation of the Universal Newborn Hearing Screening and Intervention Program (UNHSIP) in the different regions of the country; and assess the information technology (IT) capabilities of hearing centers.@*Methods@#Fifty-one NBHS centers across twelve regions were surveyed through on-site inspections in 2016. Data was gathered on the centers’ testing capability, staffing, access to specialists, use of local protocols, connectivity, and IT capabilities. @*Results@#All surveyed centers followed the recommended protocols of the Manual of Operations of the Universal Newborn Hearing Screening and Intervention Act of 2009 (RA 9709). Among the 12 regions visited, only five (41.67%) had Category C centers with confirmatory testing and early amplification services as recommended. Majority of facilities (96.1%) were staffed by trained and certified personnel. A small percentage had access to subspecialists such as clinical audiologists (39.2%) and speech-language pathologists (23.5%). All facilities had computer access, but only 58.8% had internet access. Majority (94.1%) of the centers visited were not using the recommended data submission methods, specifically the use of registry cards and the online registry. Only 27.5% of centers had data on newborns who underwent confirmatory testing or early intervention. @*Conclusion@#Facilities were found to be compliant to NBHS screening protocols and majority complied with certification requirements for staff; but were found to be non-compliant with use of registry cards or the online registry. Majority of centers were able to contact the parents of neonates who did not pass newborn screening, but had no system to track outcomes. Lack of confirmatory and early intervention services in identified areas emphasize the need for development of regional centers. It is recommended that measures to improve the utilization of the online registry are taken.

Analysis of clinical features, biochemical indices and genetic variants among children with Short/branched-chain acyl-CoA dehydrogenase deficiency detected by neonatal screening / 中华医学遗传学杂志

OBJECTIVE@#To investigate the clinical manifestations, biochemical abnormalities and pathogenic variants among children with Short/branched-chain acyl-CoA dehydrogenase (SBCAD) deficiency detected by neonatal screening.@*METHODS@#A total of 2 730 852 newborns were screened from January 2016 to December 2021 with liquid chromatography tandem mass spectrometry. Suspected SBCAD deficiency patients were diagnosed by urine organic acid analysis and high-throughput gene sequencing analysis. The clinical, biochemical and genetic changes of the confirmed cases were analyzed, in addition with guidance for diet and life management, L-carnitine supplement, and survey of growth and intellectual development.@*RESULTS@#Twelve cases of SBCAD deficiency were diagnosed, which yielded a prevalence of 1/227 571. The lsovaleryl carnitine (C5) of primary screening blood samples was between 0.6 and 2.1 µmol/L, all exceeded the normal range. C5/acety1 carnitine (C2) was between 0.02 and 0.12, with 6 cases exceeding the normal range. C5/propionyl carnitine (C3) was between 0.1 and 1.16, with 5 cases exceeding the normal range. Free carnitine (C0) was between 18.89 and 58.12 µmol, with 1 case exceeding the normal range. Three neonates with abnormal screening results were recommended to have appropriate restriction for protein intake and two were given L-carnitine. During follow-up, their C5 has ranged from 0.22 to 2.32 µmol/L, C5/C2 has ranged from 0.01 to 0.31, C5/C3 has ranged from 0.14 to 1.7. C5 or C5/C2 and C5/C3 were transiently normal in all patients except for case 8 during the neonatal screening and follow-up. C0 was 17.42 ∼ 76.83 µmol/L Urine organic acid analysis was carried out in 9 of the 12 cases, and 2-methylbutyroglycine was elevated in 8 cases. Urine organic acid analysis was carried out in 9 cases, and 2-methylbutyrylglycine was increased in 8 cases. Genetic analysis was carried out for 11 children, and in total 6 ACADSB gene variants were identified, which included 4 missense variants (c.655G>A, c.923G>A, c.461G>A, c.1165A>G), 1 frameshift variant (c.746del) and 1 nonsense variant (c.275C>G). Among these, the C.461G>A variant was unreported previously. The most common variants were c.1165A>G (40.9%) and C.275C>G (22.7%). The patients were followed up for 18 days to 55 months. Only one patient had mental retardation, with the remainders having normal physical and mental development.@*CONCLUSION@#SBCAD deficiency is a rare disease. The detection rate of newborn screening in this study was 1/227 571. Early intervention can be attained in most asymptomatic patients through neonatal screening. In this study, the common gene variants are c.1165A>G and c.275C>G.

Research progress on the prognosis of patients with various types of Methylmalonic acidemia / 中华医学遗传学杂志

Methylmalonic acidemia (MMA) is a series of rare inherited organic acid metabolic disorders with variable and nonspecific clinical manifestations, in particular neurological symptoms such as vomiting, lethargy, etc. Even with timely treatment, patients may still have various degrees of neurological complications and can even die. The prognosis is mainly related to the type of genetic variants, level of metabolites, newborn screening, onset of disease and early initiation of treatment. This article has reviewed the prognosis of patients with various types of MMA and factors that may affect it.

Results of combined newborn hearing and deafness gene screening in Yuncheng area of Shanxi Province / 中华医学遗传学杂志

OBJECTIVE@#To analyze the clinical significance of combined newborn hearing and deafness gene screening in Yuncheng area of Shanxi Province.@*METHODS@#Results of audiological examinations, including transient evoked otoacoustic emission and automatic discriminative auditory brainstem evoked potentials, for 6 723 newborns born in Yuncheng area from January 1, 2021 to December 31, 2021, were retrospectively analyzed. Those who failed one of the tests were considered to have failed the examination. A deafness-related gene testing kit was used to detect 15 hot spot variants of common deafness-associated genes in China including GJB2, SLC26A4, GJB3, and mtDNA12S rRNA. Neonates who had passed the audiological examinations and those who had not were compared using a chi-square test.@*RESULTS@#Among the 6 723 neonates, 363 (5.40%) were found to carry variants. These have included 166 cases (2.47%) with GJB2 gene variants, 136 cases (2.03%) with SLC26A4 gene variants, 26 cases (0.39%) with mitochondrial 12S rRNA gene variants, and 33 cases (0.49%) with GJB3 gene variants. Among the 6 723 neonates, 267 had failed initial hearing screening, among which 244 had accepted a re-examination, for which 14 cases (5.73%) had failed again. This has yielded an approximate prevalence of hearing disorder of 0.21% (14/6 723). Among 230 newborns who had passed the re-examination, 10 (4.34%) were found to have carried a variant. By contrast, 4 out of the 14 neonates (28.57%) who had failed the re-examination had carried a variant, and there was a significant difference between the two groups (P < 0.05).@*CONCLUSION@#Genetic screening can provide an effective supplement to newborn hearing screening, and the combined screening can provide a best model for the prevention of hearing loss, which can enable early detection of deafness risks, targeted prevention measures, and genetic counseling to provide accurate prognosis for the newborns.

Analysis of clinical characteristics and ACADM gene variants in four children with Medium chain acyl-CoA dehydrogenase deficiency / 中华医学遗传学杂志

OBJECTIVE@#To explore the clinical and genetic characteristics of four patients with medium-chain acyl-CoA dehydrogenase deficiency (MCADD).@*METHODS@#Four children who had presented at the Children's Hospital Affiliated to Zhengzhou University between August 2019 and August 2021 were selected as the study subjects. Clinical data of the children were collected. The children were subjected to whole exome sequencing (WES).@*RESULTS@#All of the four children were diagnosed with MCADD. Blood amino acid and ester acyl carnitine spectrum test showed that the concentration of octanoyl carnitine (C8) was significantly increased. The main clinical manifestations included poor mental response (3 cases), intermittent diarrhea with abdominal pain (1 case), vomiting (1 case), increased transaminase (3 cases), and metabolic acidosis (2 cases). Five variants were identified by genetic testing, among which c.341A>G (p.Y114C) was unreported previously. Three were missense variants, one was frameshift variant and one was splicing variant.@*CONCLUSION@#The clinical heterogeneity of MCADD is obvious, and the severity of the disease may vary. WES can assist with the diagnosis. Delineation of the clinical symptoms and genetic characteristics of the disease can facilitate early diagnosis and treatment of the disease.

A prospective study of genetic screening of 2 060 neonates by high-throughput sequencing / 中华医学遗传学杂志

OBJECTIVE@#To assess the value of genetic screening by high-throughput sequencing (HTS) for the early diagnosis of neonatal diseases.@*METHODS@#A total of 2 060 neonates born at Ningbo Women and Children's Hospital from March to September 2021 were selected as the study subjects. All neonates had undergone conventional tandem mass spectrometry metabolite analysis and fluorescent immunoassay analysis. HTS was carried out to detect the definite pathogenic variant sites with high-frequency of 135 disease-related genes. Candidate variants were verified by Sanger sequencing or multiplex ligation-dependent probe amplification (MLPA).@*RESULTS@#Among the 2 060 newborns, 31 were diagnosed with genetic diseases, 557 were found to be carriers, and 1 472 were negative. Among the 31 neonates, 5 had G6PD, 19 had hereditary non-syndromic deafness due to variants of GJB2, GJB3 and MT-RNR1 genes, 2 had PAH gene variants, 1 had GAA gene variants, 1 had SMN1 gene variants, 2 had MTTL1 gene variants, and 1 had GH1 gene variants. Clinically, 1 child had Spinal muscular atrophy (SMA), 1 had Glycogen storage disease II, 2 had congenital deafness, and 5 had G6PD deficiency. One mother was diagnosed with SMA. No patient was detected by conventional tandem mass spectrometry. Conventional fluorescence immunoassay had revealed 5 cases of G6PD deficiency (all positive by genetic screening) and 2 cases of hypothyroidism (identified as carriers). The most common variants identified in this region have involved DUOX2 (3.93%), ATP7B (2.48%), SLC26A4 (2.38%), GJB2 (2.33%), PAH (2.09%) and SLC22A5 genes (2.09%).@*CONCLUSION@#Neonatal genetic screening has a wide range of detection and high detection rate, which can significantly improve the efficacy of newborn screening when combined with conventional screening and facilitate secondary prevention for the affected children, diagnosis of family members and genetic counseling for the carriers.

Neonatal hearing screening programs: quality indicators and access to health services / Programas de triagem auditiva neonatal: indicadores de qualidade e acesso aos serviços de saúde

Abstract Objectives: to verify the quality indicators of neonatal hearing screening programs, identify the most prevalent risk factors for hearing loss and analyze access to the Hearing Health Care Network. Methods: cross-sectional study using secondary data. The population are children born in public maternity hospitals from 2015 to 2019. Data collection was carried out in the database of programs and hearing health service. The absolute and relative frequencies of all variables collected and the median, the interquartile range and the Mann-Whitney test were calculated to analyze the access. Results: universality increased during the study period, but was not reached (71.9%; CI95%=70.4-73.3) and the referral rate for auditory diagnosis was within the recommended range (0.9%; CI95%=0.8-0.9). The most prevalent risk factors were congenital infections and heredity. There was an evasion of children to the hearing health service of 85.1% and the type of referral interfered with the age of the child at access. Eight children with hearing loss were diagnosed, in which seven had access to therapeutic interventions. Conclusions: hearing screening was not universal. Access to the Hearing Health Care Network presents high evasion and interventions were offered to children with hearing loss.
