About me

  • Nele is a medical doctor and epidemiologist, specialised in clinical- and pharmaco-epidemiology. She is a senior researcher and associate professor, and has worked at Karolinska Institutet since 2012. Nele combines this with a position as Professor in Pharmaco-epidemiology at the Global Health Institute, at the University of Antwerp in Belgium (since end 2020). She has a broad interest and experience in different clinical topics with a main focus on long-term effects of commonly prescribed drugs on long-term health and the microbiome, with a focus on women's health, early life, cancer and infections. She has extensive experience in evidence synthesis methodologies (systematic reviews, meta-analyses etc. ), the Swedish Health Registries and various clinical and microbiome cohorts.

Research

  • I am the principal investigator of 5 large cohorts:
    - Chemoprevention of cancer cohort (aim: to assess the impact of commonly prescribed drugs on the development of cancer)
    - The Swedish Maternal Microbiome (SweMaMi) project (aim: to assess how the microbiome affects pregnancy outcomes and the health of the offspring) www.swemami.se
    - Medication and the Maternal Microbiome (MediMami) project (aim: to assess the impact of commonly prescribed drugs during pregnancy, through potential microbiome alterations)
    - PCOS (Polycystic Ovary syndrome) project (aim: to assess the effects on health in the offspring of mothers with PCOS)
    - CDI project: /Clostridioides difficile/ infection [CDI], recurrence and mortality in Sweden: risk profiles, prescription drugs and burden.

    Our gut microbiome is affected by many factors, including drug use. The first years of life are crucial to establish a healthy, stable gut microbiome, yet infancy is also when most antibiotics are used and many receive gastric acid inhibition. As these drugs are known to disrupt the adult microbiome, the effects in infants could be worse. We will assess how these drugs affect the microbiome and health during early life. First  we will assess the gut microbiome of 3000 babies, born into our large Swedish longitudinal pregnancy microbiome cohort. Second, 400 infants operated during their first days/months of life will be enrolled, of which part receive routine gastric acid inhibition for at least one year. Through repeated stool microbiome collection, questionnaires and registry linkages, we can assess how their microbiome and health are affected and restored. The third and fourth projects are based on the high quality nationwide Swedish registries, to assess how maternal/early life drug use affects the risk of neonatal complications and infections.  In the fifth project, we will assess global antibiotics and gastric acid inhibitors utilisation during infancy (meta-analysis).  With these projects, we want to contribute to the understanding of drug-microbiome interactions in young children, and understand the long-term health consequences. These projects can have direct clinical implications, by contributing to better prescription practices and reducing inappropriate intake.
