ABSTRACT

Manifestações bucais da anemia estão entre os diversos sinais e sintomas associados à doença, tornando a participação do cirurgião-dentista de fundamental importância no processo de diagnóstico e tratamento dos pacientes. Objetivo: avaliar pacientes diagnosticados com anemia e identificar possíveis manifestações bucais, buscando esclarecer o mecanismo causal por trás da relação entre a manifestação bucal encontrada e o tipo diagnosticado de anemia. Materiais e método: por meio da avaliação de pacientes portadores de anemia, este trabalho quer relacionar quadros clínicos de pacientes oriundos do Hemocentro do Hospital Universitário da Universidade Estadual de Maringá com eventuais manifestações bucais passíveis de reconhecimento por meio de exame clínico e/ou radiográfico. Resultados: dos 21 pacientes analisados, as alterações mais identificadas estão na palidez de mucosa (66,67 %), na doença periodontal (38,09 %), na atresia papilar lingual (38,09 %) e na pigmentação dentária (28,57 %). Conclusões: pacientes portadores de anemia falciforme e pacientes com ?-talassemia exibiram alterações extrabucais, ao passo que pacientes portadores de anemia por deficiência vitamínica foram os que mais apresentaram atresia papilar lingual (62,5 %).

ABSTRACT

We evaluated the usefulness of blood group genotyping as a supplement to hemagglutination to determine the red blood cell (RBC) antigen profile of polytransfused patients with hematological diseases and renal failure. Seventy-nine patients were selected. They all received more than three units of blood and eight (10%) had already clinical significant alloantibodies occurring alone or in combination against Rh, K, Fya, and Di antigens. DNA was prepared from blood samples and RHCE*E/e, KEL*01/KEL*02, FY*01/FY*02 and JK*01/JK*02 alleles were determined by using PCR-RFLP. RHD*/RHD*Ψ and RHCE*C/c were tested using multiplex PCR. Discrepancies for Rh, Kell, Duffy, and Kidd systems were found between the phenotype and genotype-derived phenotype in 16 of the 38 chronically transfused patients. The genotypes of these patients were confirmed by DNA array analysis (HEA Beadchip(™); Bioarray Solutions, Warren, NJ). Genotyping was very important for the determination of the true blood groups of the polytransfused patients, helped in the identification of suspected alloantibodies and in the selection of antigen-negative RBCs for transfusion.
