Resumo: | Introduction: Genetic causes are responsible for half of the cases of hearing loss, most of them being the result of non-syndromic genetic changes resulting from autosomal recessive inheritance. Parental consanguinity might be an indicator to consider in the diagnosis of these cases. The aim of this study was to assess its importance as a risk factor for childhood hearing loss.Material and Methods: A retrospective cohort study conducted in a district hospital, between 2014 and 2018. We included all live births born during this period and excluded those with risk factors for childhood hearing loss other than parental consanguinity and those without hearing screening. We formed two study groups: newborns with parental consanguinity and newborns without risk factors. All the participants underwent hearing screening with the primary outcome of this study being the result of the screening. Those with a not normal result or with parental consanguinity also underwent diagnostic audiological evaluation.Results: Among 8513 live births, we studied 96 newborns with first-degree parental consanguinity and 96 newborns without risk factors. We found a statistically significant difference (p = 0.007) between the groups, with a ‘refer’ screening result rate of 24% in the group with parental consanguinity and 9.4% in the group without risk factors. We diagnosed one case of sensorineural hearing loss and another of mixed hearing loss in the first group andnone of these cases in the second.Conclusion: Parental consanguinity was associated with a higher risk of a refer screening result in newborns, which suggests the need to consider this as a risk factor for childhood hearing loss. |

A consanguinidade parental constitui um possível indicador a considerar para o diagnóstico destes casos, pelo que este estudo pretende avaliá-la como fator de risco para a surdez infantil.Material e Métodos: Estudo de coorte retrospetivo realizado de 2014 a 2018 num hospital distrital. Incluímos todos os nados-vivos nascidos neste período, sendo excluídos aqueles com outros fatores de risco para surdez infantil (que não a consanguinidade parental) e aqueles sem rastreio auditivo. Formámos dois grupos de estudo: recém-nascidos com consanguinidade parental e recém-nascidos sem fatores de risco. Todos os participantes realizaram rastreio auditivo, sendo o seu resultado o outcome primário do estudo. Aqueles com resultado anormal ou com consanguinidade parental efetuaram ainda avaliação audiológica diagnóstica.Resultados: Entre os 8513 nados-vivos, estudámos 96 recém-nascidos com consanguinidade parental em primeiro grau e 96 recém-nascidos sem fatores de risco. Verificámos uma diferença estatisticamente significativa (p = 0,007) entre os grupos relativamente aos resultados do rastreio auditivo, tendo-se detetado uma taxa de refer de 24% no grupo com consanguinidade parental e de 9,4% naquele sem fatores de risco. Diagnosticámos um caso de surdez sensorioneural e outro de surdez mista no primeiro grupo e zero destes casos no segundo.Conclusão: A consanguinidade parental associou-se a um risco significativamente superior de resultado refer no rastreio auditivo de recém-nascidos com consanguinidade parental e sugere a necessidade de considerar este critério como um fator de risco para surdez infantil.Ordem dos Médicos2023-02-17info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttps://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/18607Acta Médica Portuguesa; Vol. 36 No. 5 (2023): May; 336-342Acta Médica Portuguesa; Vol. 36 N.º 5 (2023): Maio; 336-3421646-07580870-399Xreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAPenghttps://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/18607https://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/18607/15046Direitos de Autor (c) 2023 Acta Médica Portuguesainfo:eu-repo/semantics/openAccessLeal, BárbaraLopes, Ana CristinaPeixoto, DanielaCorreia, LauraAlmiro, Maria MiguelVilar, JoãoAzevedo, Maria LuísaBicho, Maria Adelaide2023-05-07T03:00:35Zoai:ojs.www.actamedicaportuguesa.com:article/18607Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T16:46:58.059668Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
