The Department of Clinical Biochemistry continuously contributes to research with development of new assays for diagnosing and monitoring childhood diseases. Furthermore, the department contributes with clinical biochemical analyses in almost all clinical projects involving children at AUH.
Projects in progress
1. Establishment of reference intervals for children
We contribute to ongoing projects which take place under the auspices of the Danish Society for Clinical Biochemistry.
Contact person: Consultant, DMSc., PhD Søren Ladefoged, email@example.com
2. Coagulation in children
We characterise full blood coagulation and thrombocyte function in healthy children, and examine changes in full blood coagulation and thrombocyte function during and after cardiac surgery. Furthermore, we investigate the effect of haemostatic drugs.
Contact person: Professor, PhD Anne-Mette Hvas, firstname.lastname@example.org
3. Neonatal sepsis
We examine the best suitable diagnostic markers for diagnosing neonatal sepsis; we use blood from the umbilical cord and venous samples from the children at early and late stages of neonatal sepsis.
Contact person: Professor, PhD Anne-Mette Hvas, email@example.com
4. Mitochondrial metabolic diseases in children and newborns
We examine children suspected of inborn errors in the mitochondria; especially mutations in genes coding for enzymes involved in fatty acid oxidation and proteins involved in cellular quality control. We receive samples from all over the world; moreover, we obtain all samples suspected to include inborn errors in fatty acid oxidation after postnatal screening at the Statens Serum Institut.
Contact persons: Associate Professor, PhD Rikke Olsen, firstname.lastname@example.org and Professor, M.D. Niels Gregersen, email@example.com
5. Inherited vitamin B12 deficiency
We examine children suspected of deficiency in transcobalamin, a transport protein for B12 in serum, which is sometimes involved in vitamin B12 deficiency. We receive samples from all over the world.
Contact person: Professor, DMSc. Ebba Nexø, firstname.lastname@example.org
6. Vitamin status and nutrition with mother’s milk
We examine for how long newborns can get sufficient vitamin supplythrough mother’s milk alone.
Contact person Vitamin B12: Professor, DMSc. Ebba Nexø, email@example.com
Contact person Vitamin D: Executive Consultant, Associate Professor, DMSc. Lene Heickendorff, firstname.lastname@example.org
7. Early diagnosis of inherited diseases
We examine biochemical marker proteins which can be used for prenatal screening for foetal aneuploidy and other chromosomal changes.
Contact person: Associate professor, PhD Niels Tørring, email@example.com
8. Macrophage-related biomarkers in children
We examine soluble CD163 and other macrophage-related serum-proteins in conditions such as obesity, liver disease, diabetes, and sickle-cell disease in children.
