worlDwIde cOllaboratioN for hemolYtic diSease of the fetUS and newborn study

International collaborations are of utmost importance to gain a better understanding of rare diseases and improve care for those affected. So, we are very glad to announce that we have launched an international collaborative study for Hemolytic Disease of the Fetus and Newborn (HDFN)! The DIONYSUS (worlDwIde cOllaboratioN for hemolYtic diSease of the fetUS and newborn) study, initiated by the Leiden University Medical Center, Sanquin Research and Sanquin Diagnostic Services, aims to gain a better insight and understanding into what prenatal and postnatal treatments for pregnancies and newborns complicated with HDFN are used in expert fetal care centers around the world. For this, we will be looking into retrospective data of cases affected by HDFN, in close collaboration with 35 centers from 23 countries. 


In September 2022, 25 centers have started collection and 10 other centers are awaiting judicial and/or ethical approval. Thus far already over 1100 cases have been entered, making this the largest HDFN cohort to be ever reported on.

We will also be collaborating in several projects in Sub-Saharan Africa researchers and clinicians from the Kilimanjaro Christian Medical Center in Tanzania, among others.

Updates and information on the DIONYSUS study will be posted here!
