Show moreAim: To investigate the school performance and behavioral difficulties in children with hemolytic disease of the fetus and newborn (HDFN) treated with intrauterine transfusion (IUT) compared to Dutch norm data.Study design: Cros-sectional cohort study. Subjects: Children who received one or multiple IUTs for severe Rh-or K (Kell)-mediated HDFN between January 2008 and January 2015 at the LUMC.Outcome measures: School performance reports were assessed as well as behavioral difficulties as assessed with the Dutch child behavioral checklist (CBCL) by parents and caregivers and the Teacher Report Form (TRF) completed by teachers.Results: A response rate of 56% (70 children, aged 5-12 years) was obtained. Grade repetition occurred in 13 cases (19%), 16 children (23%) received some form of additional help, most often support by a speech therapist (n = 8), but also support for dyslexia (n = 4), physical therapy (n = 2) and social-emotional support (n = 2). None of the children in our study group attended special-needs education. School performance levels for reading comprehension, spelling and mathematics according to the Dutch National Pupil Monitoring System were similar for the study population and Dutch norm data. The incidence of behavioral problems as reported by parents was similar to the Dutch norm data, teachers reported less behavioral difficulties in the study group. Conclusion: This study shows favorable and reassuring school development in children treated with IUT in an experienced fetal-therapy center. A normal distribution in school and behavioral development is to be expected for children with HDFN treated with IUTs. Show less

Show moreBACKGROUND: Fetal bilirubin is routinely measured at our center when taking a pretransfusion blood sample at intrauterine transfusions in hemolytic disease of the fetus and newborn. However, the clinical value of fetal bilirubin assessment is not well known, and the information is rarely used. We speculated that there could be a role for this measurement in predicting the need for neonatal exchange transfusion.OBJECTIVE: This study aimed to evaluate the predictive value of fetal bilirubin for exchange transfusions in severe hemolytic disease of the fetus and newborn.STUDY DESIGN: A total of 186 infants with Rh alloantibody-mediated hemolytic disease of the fetus and newborn treated with one or more intrauterine transfusions at the Leiden University Medical Center between January 2006 and June 2020 were included in this observational study. Antenatal and postnatal factors were compared between infants with and without exchange transfusion treatments. The primary outcome was the fetal bilirubin levels before the last intrauterine transfusion in relation to the need for exchange transfusion.RESULTS: In a multivariate logistic regression analysis, the fetal bilirubin level before the last intrauterine transfusions (odds ratio, 1.32; 95% confidence interval, 1.09-1.61 per 1 mg/dL) and the total number of intrauterine transfusions (odds ratio, 0.63; 95% confidence interval, 0.44-0.91 per intrauterine transfusion) were independently associated with the need for exchange transfusion. The area under the curve was determined at 0.71. A Youden index was calculated at 0.43. The corresponding fetal bilirubin level was 5 mg/dL and had a sensitivity of 79% and a specificity of 64%.CONCLUSION: A high fetal bilirubin level before the last intrauterine transfusion was associated with a high likelihood of neonatal exchange transfusion.

Show moreBackground and objectives Guidelines and indications for exchange transfusion in haemolytic disease of the foetus and newborn (HDFN) have changed drastically in the past decades, causing a decline in exchange transfusion rate. This study aims to evaluate the incidence of exchange transfusions (ETs) in neonates with Rh-mediated HDFN over the past 20 years at our centre, and report potentially ET-related complications as well as indicators for bilirubin encephalopathy.Material and methods In this observational study, 438 neonates were included with HDFN, born >= 35 weeks gestational age at the Leiden University Medical Centre between January 2000 and July 2020. The incidence of ET and procedure-related complications were assessed in three consecutive time periods determined by changes in guidelines and indications for ET.Results The incidence of ET in our centre declined from (104/156) 67% (time period 2000-2005), to (39/181) 22% (2006-2015) and to (10/101) 10% (2015-2020, p < 0 center dot 001). The maximum bilirubin levels in neonates after birth increased from 13 center dot 6 mg/dL (or 233 mu mol/L), to 15 center dot 0 mg/dL (257 mu mol/L) and to 15 center dot 3 mg/dL (263 mu mol/L). The incidence of complications associated with the use of ET (including sepsis, haematologic disorders and respiratory failure) remained stable throughout the years, and no neonates died during the study period.Conclusion Exchange transfusion incidence declined significantly over the past two decades. Decrease in ET incidence, and concomitant decrease in exposure and expertise, was not associated with an increase in procedure-related complications. Show less
