Jantien Wieringa

Jantien Wieringa is a Researcher in the Department of Pediatrics at Erasmus University Medical Center. She specializes in pediatric immunology and pharmacotherapy, with a focus on inflammatory bowel disease (IBD), immunomodulation, and the effects of biologic agents during pregnancy and early development.

Research Focus: Her work bridges immunology, pharmacology, and clinical pediatrics. Key areas include:

• Pharmacokinetics of anti-TNFα agents (infliximab, adalimumab) and ustekinumab in infants
• Impact of maternal immunomodulation on infant immunity and vaccine responses
• Development of clinical guidelines for IBD management during pregnancy
• Immune system development in early life under IBD conditions

Research Trends: Recent publications (2023–2025) demonstrate consistent focus on:

• Safety/efficacy of biologic therapies during pregnancy
• Pharmacokinetic modeling of drug clearance in infants
• Clinical guideline development for reproductive health in IBD patients
• Maternal vaccination outcomes under immunomodulation

Collaborations: Active in multinational consortia including the PETIT study and NEXUS Collaborator Group, contributing to large-scale clinical research on IBD and pregnancy.
