Almost every premature infant admitted to a neonatal intensive care unit is affected by anaemia and/or thrombocytopenia. Analysing innovative parameters of the full blood count by fully-automated analysers is helpful to evaluate neonatal thrombocytopenia. We could demonstrate that the immature platelet fraction (IPF) is useful parameter in predicting the course of neonatal thrombocytopenia. This parameter is now under investigation in a prospective trial in combination with other megakaryopoietic parameters in premature infants. On the other hand, regulation of haematopoiesis by cytokines and growth factor is complex. The therapy of the anaemia of prematurity with erythropoietin results in a marginal effect erythropoiesis and only the minority of premature infants profit from such therapy. We are investigating with other factors may contribute to anaemia of prematurity. Similar questions are answered in animal models of congenital thrombocytopenia.

Protection of the immature brain against high oxygen-mediated damage
Principal Investigator: Dr. Stefanie Endesfelder
The growing understanding of molecular mechanisms involved in the increased sensitivity of the developing brain towards various conditions such as high oxygen, anti-epileptic drugs or mediators of inflammation provides opportunities to specifically search for potentially protective medications. Experiments carried out in vivo (employing newborn rats) and in vitro (employing cultured fetal or neonatal brain cells) complement each other to elucidate signal transduction pathways and characterize the interaction of neurons, oligodendrocytes, astrocytes, microglia, and endothelial cells.

Pain assessment and therapy in newborns
Principal Investigator: Lars Garten, MD
Aside from being exposed to stress resulting from their illnesses, newborns on the intensive care unit often experience pain. Despite a significant increase in our knowledge of neonatal pain in recent years, many questions remain unanswered. Our clinical research focuses on different fields of neonatal pain research, e.g. new methods for pain assessment in premature and full-term infants or differences in the use of opioids during palliative care in neonatal and paediatric intensive care units.
