Although anti-D prophylaxis has greatly reduced the rate of Rh-immunization, there remain women who sensitize during or after pregnancy because of inadequate prophylaxis.

Hematology analyzers with flow cytometry capabilities may be adapted for fetal cell detection, thus giving clinical laboratories a potentially attractive automated alternative for quantifying FMH. A total of 44 samples with partial D phenotypes were confirmed. Prenatal noninvasive determination of fetal Rh status is an important aid to the management of hemolytic disease of the fetus and newborn.

Realizaram-se entrevistas com 15 atores sociais, individualmente. Among these women, Among weak D samples, 76 weak D type 1 This development is highly likely to allow use of anti-D in only those pregnant women carrying rhesus-positive fetuses. There is strong evidence for the effectiveness of routine antenatal anti-D prophylaxis for prevention of sensitisation, in support of the policy of offering routine prophylaxis to all non-sensitised pregnant Rhesus negative women.


A total of patients underwent exchange transfusions. We found detectable levels of anti-D IgG within two weeks of parturition in 11 of 12 women.

Our results showed that the use of different methods and anti-D reagents in the serologic routine analysis revealed D variants that can be further investigated. Kinetic profiles for anti-D levels were generated from the concentration hemolitlca at predetermined sampling time points.

RhD alloimmunization in pregnant women in Rio de Janeiro State, Brazil: perspectives and challenges

ABO-incompatible fetal red cells may be cleared rapidly, but in some cases they circulate for weeks. The purpose of this study was to compare adherence to prophylaxis recommendations for antenatal and postnatal anti-D immunoglobulin administration.

Alternative strategies may be evaluated in the future, with repeated administration of antenatal prophylaxis at term rather than conventional postpartum administration of anti-D. All infants admitted doencq treat hemolytic disease secondary to Rhesus Alloimunoization in the Neonatal Intensive Care Unit were enrolled in the study. Feedback Privacy Policy Feedback. Published by Quinn Bickford Modified over 3 years ago. Antenatal administration was analyzed in pregnancies in eligible Rh-negative women.

Erros in anti-D immunoglobulin administration: As described previously, DVI pperinatal the most frequent partial D type in China with a total of 36 samples. We think you have liked this presentation. Noninvasive prenatal RHD genotyping by real-time polymerase chain reaction using plasma from D-negative pregnant women.

Serologic and molecular characterization of D variants in Brazilians: How to cite this article.

However, discrepant results were observed in four DVI samples with serotyping and genotyping i. Se realizaron entrevistas con 15 actores sociales, individualmente. Incidence of adverse events was determined, as well as the relative risk of each adverse event.


Las entrevistas presentaron factores que contribuyeron a la persistencia del problema como: We conducted a retrospective cohort study of all pregnancies recorded at the Royal Victoria Hospital between and to determine the rates of antenatal and postnatal prophylaxis in Rh D -negative women.

Maternal and child health in Brazil: Potential sources of bias were systematically identified using bias checklists, and their impact and dkenca were quantified using expert opinion.

The interviews revealed factors contributing to persistence of the problem, such as: During her third pregnancy, she was genotyped as a partial D antigen, which was reported as Rh-negative.
