Resumo: | Hemoglobinopathies are hereditary disorders of the hemoglobin molecule with a high prevalence worldwide. Brazil has a prevalence of 0.1 to 0.3% of newborns with sickle cell anemia and 20.0 to 25.0% of heterozygous alpha2 thalassemia among African Brazilians. In the present study, we investigated the presence of variant hemoglobins and alpha2(3.7 Kb) and alpha2(4.2 Kb) thalassemia in newborns from Salvador, Bahia, Brazil. Samples of umbilical cord blood from a total of 590 newborns were analyzed, of which 57 (9.8%) were FAS; 36 (6.5%) FAC; one (0.2%) SF; and five (0.9%) FSC. One hundred fourteen (22.2%) newborns had alpha2(3.7 Kb) thalassemia, of whom 101 (19.7%) were heterozygous and 13 (2.5%) homozygous, showing statistical significance for hematological data between newborns with normal alpha genes and alpha2(3.7 Kb) thalassemia carriers. The alpha2(4.2 Kb) thalassemia was not found. Frequencies found in the present study confirm that hemoglobinopathies are a public health problem in Brazil, emphasizing the need for neonatal screening and genetic counseling programs. |

O Brasil apresenta prevalência de 0,1 a 0,3% para recém-nascidos com anemia falciforme e freqüência de 20,0 a 25,0% para a ocorrência de heterozigotos da talassemia alfa2 entre indivíduos afro-descendentes. O presente estudo investigou a presença de hemoglobinas variantes e talassemia alfa2(3.7Kb) e alfa2(4.2Kb) em recém-nascidos de Salvador, Bahia, Brasil. Analisamos o sangue do cordão umbilical de 590 recém-nascidos, sendo 57 (9,8%) com padrão FAS; 36 (6,5%) FAC; um (0,2%) SF e cinco (0,9%) FSC. Cento e catorze (22,2%) apresentaram talassemia alfa2(3.7Kb), dos quais 101 (19,7%) foram heterozigotos e 13 (2,5%) homozigotos, mostrando significância estatística para os dados hematológicos entre recém-nascidos com genes alfa normais e portadores de talassemia alfa2(3.7Kb). A talassemia alfa2(4.2Kb) não foi encontrada. As freqüências descritas neste trabalho confirmam que as hemoglobinopatias são um problema de Saúde Pública no Brasil, enfatizando a importância dos programas de triagem neonatal e aconselhamento genético.Reports in Public HealthCadernos de Saúde Pública2005-02-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontext/htmlapplication/pdfhttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/2571Reports in Public Health; Vol. 21 No. 1 (2005): January/FebruaryCadernos de Saúde Pública; v. 21 n. 1 (2005): Janeiro/Fevereiro1678-44640102-311Xreponame:Cadernos de Saúde Públicainstname:Fundação Oswaldo Cruz (FIOCRUZ)instacron:FIOCRUZenghttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/2571/5158https://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/2571/5159Adorno, Elisângela VitóriaCouto, Fábio DavidMoura Neto, José Pereira deMenezes, Joelma FigueiredoRêgo, MarcoReis, Mitermayer Galvão dosGonçalves, Marilda Souzainfo:eu-repo/semantics/openAccess2024-03-06T15:27:06Zoai:ojs.teste-cadernos.ensp.fiocruz.br:article/2571Revistahttps://cadernos.ensp.fiocruz.br/ojs/index.php/csphttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/oaicadernos@ensp.fiocruz.br||cadernos@ensp.fiocruz.br1678-44640102-311Xopendoar:2024-03-06T13:03:00.327719Cadernos de Saúde Pública - Fundação Oswaldo Cruz (FIOCRUZ)true |
