14. Study of possible clinical and laboratory predictors of alloimmunization against red blood cell antigens in cancer patients
Background: The inflammatory background of patients influences the process of alloimmunization against red blood cell antigens. Proof of this statement to clinical practice is still lacking. Objective: The aim of this study was to verify whether factors related to disease severity and inflammatory status of cancer patients can predict alloimmunization.

16. Molecular matching of red blood cells is superior to serological matching in sickle cell disease patients
OBJECTIVE: To evaluate the usefulness of DNA methods to provide a means to precisely genotypically match donor blood units for the antigen-negative type of 35 sickle cell disease patients<. METHODS: Red blood cell units were investigated for ABO, D, C, c, E, e, K, Fyª, Fy b, Jkª, Jk b, S, s, Diª and RH variants by performing a molecular array (Human Eryth

17. Identification of platelet refractoriness in oncohematologic patients
OBJECTIVES: To identify the occurrence and the causes of platelet refractoriness in oncohematologic patients. INTRODUCTION: Platelet refractoriness (unsatisfactory post-transfusion platelet increment) is a severe problem that impairs the treatment of oncohematologic patients and is not routinely investigated in most Brazilian services. METHODS: Forty-four ep

18. Transfusão de plaquetas: do empirismo ao embasamento científico
Despite major advances in Brazilian blood transfusion therapy with a growing number of scientific publications, an increased number of repeat donors and a decline in serological ineligibility, a lack of conformity in the application of pre-transfusion tests that may compromise transfusion safety is still observed at transfusion agencies in the fringes of the

19. Fenotipagem e aloimunização eritrocitária em portadores de anemia falciforme atendidos no Hemocentro de Alagoas / Erythrocyte phenotyping and alloimmunization in patients with sickle cell anemia assisted at HEMOAL from Alagoas
Objetivo: Determinar a imunofenotipagem eritrocitária em doadores de sangue e em pacientes com anemia falciforme (SS) atendidos no Hemocentro de Alagoas, além de descrever a frequência e os fatores associados à aloimunização eritrocitária. Método: Estudo transversal realizado com 102 pacientes com anemia falciforme (SS) e 100 doadores de sangue. Estu

20. relação entre a concentração plasmática do peptídeo natriurético tipo b, índice cardiofemoral e equilíbrio ácido-básico em fetos de gestantes isoimunizadas
Introduction: Fetal anemia is a common result of alloimunization and is an important cause of fetal congestive heart failure resulting in heart dilation. Fetuses suspected of having heart failure present a higher cardiofemoral index and an increase in plasma BNP levels, because the cardiac hormonal system is activated by increased heart wall stretch due to i

21. Risk factors for alloimmunization by patients with sickle cell disease
Blood transfusion in patients with sickle cell disease (SCD) is limited by the development of alloantibodies to erythrocytes. In the present study, the frequency and risk factors for alloimmunization were determined. Transfusion records and medical charts of 828 SCD patients who had been transfused and followed at the Belo Horizonte Blood Center, Belo Horizo

22. Estudo dos polimorfismos dos sistemas de aloantigenos plaquetarios humanos (HPA) em doenças hemorragicas e tromboticas
Human platelet alloantigens (HP A) are polymorphic sequencies of the platelet membrane glycoproteins, which are associated to immune platelet disorders, such as neonatal alloimmune thrombocytopenia (NAIT), post-transfusion purpura (PTP), platelet transfusion reftactoriness and may be to related to occlusive vascular disease. Several distinct biallelic system

23. Alloantibodies and Australia antigen after open heart surgery
The development of irregular serum antibodies (alloantibodies) following massive transfusion was studied in 144 patients who had undergone cardiac valve replacement. An overall incidence of alloimmunization of 8·3% was found. Of the 15 antibodies detected nine were Rhesus anti-E and four anti-Kell. The incidence of anti-E formation in Rhesus E-negative pati

24. Intrauterine transfusion with red cells and platelets.
Having direct access to the fetoplacental circulation by ultrasound-directed needle puncture has led to therapeutic interventions for fetal anemia and thrombocytopenia. Most cases of red cell alloimmunization associated with fetal anemia are caused by the antibody to the D red cell antigen. The intravascular transfusion of red cells to a hydropic fetus in su
