Research lineDescriptionPI
Pediatric Viral Infectious DiseasesWith the use of human organoid technology, researchers within OrganoVIR labs investigate the effects of picornaviruses, HIV, CMV and SARS-CoV2 on these models, to increase our understanding of the mechanism of disease in humans.Adithya Sridhar
Development of human disease modelsThis research aims to establish human disease models for studying infectious diseases. Here, we use human stem cells to generated organotypic models of the human intestinal tract, human airway, and the central nervous system. These models are then used in the subsequent research lines for studying viral pathogenesis and antiviral testing.Adithya Sridhar
Understanding Dengue virus neuropathogenesisAdvanced technologies, such as a brain-on-chip model, will be used to study dengue's impact on the nervous system.Adithya Sridhar
Drug repurposing for chronic intestinal viral infectionsIn this research line, we use human intestinal organoids to test potential antivirals for patients suffering from chronic intestinal infections. Specifically, antiviral effects of clinically approved compounds is tested against patient isolated viruses in an human intestinal model.Adithya Sridhar

Familiaire HypercholesterolemieOur research focuses on the treatment and outcomes of children with Familial Hypercholesterolemia (FH). FH is a genetic disorder that leads to high cholesterol levels, increasing the risk of cardiovascular disease from a young age. Our research aims to understand how early intervention can improve long-term health outcomes for individuals with FH. We are investigating various treatment strategies, monitoring their effects on cholesterol levels, and evaluating potential impacts on the prevention of heart disease. By closely tracking both short-term and long-term results, we hope to enhance the understanding of atherosclerosis in FH and develop optimized treatment protocols. Ultimately, our goal is to improve the quality of life and lifespan for children diagnosed with this condition. Furthermore we investigate the role of high Lp(a) in childhood.Albert Wiegman
Strengthening Transgender Care for AdolescentsAdolescent transgender care is a relatively new field that is rapidly developing. It has its roots in the Netherlands and I have been at the forefront of what has become known as the ‘Dutch model’. It includes early medical intervention and is at present the internationally dominant care model and was shown to have positive effects in my first longer-term evaluation studies and in recent other outcome publications. Puberty blocking, with no permanent effects, relieves the acute psychological distress of transgender youth when they experience the physical changes of puberty. It provides time and rest before making decisions regarding masculinizing or feminizing hormones and gender affirming surgeries with life-long consequences.
The increased visibility, acceptance and availability of medical gender affirming care is a positive development in a society that embraces diversity and tolerance. Meanwhile, transgender care for adolescents is surrounded by challenges and uncertainties, since medically intervening in a developing adolescent body remains an essential though controversial component of transgender care. Threats to providing affirming medical care exist in various countries.
My current research addresses several questions. A topical concern involves the limited evidence base for the care model, especially for the more recent referred adolescents. A key concern is whether these ‘older’ birth assigned girls may present with a ‘new’ form of (rapid or sudden) onset adolescent GI/GD, who may regret their treatment and detransition later. There is a need for more insight how the diversity of developmental pathways and associated psychological difficulties is related to treatment outcomes. Meanwhile, youth, adolescents and their parents report an explicit wish to be more engaged in treatment-associated decisions. This asks for investigation of what good decision-making in gender affirming treatment should comprise.

TTV-TXTorque Teno Virus (TTV) belongs to the Anelloviruses. The measurement of TTV in blood might be of additional value in the personalized dosing of immunosuppression in children after kidney transplantation, besides the blood concentration levels of immunosuppressive medication. A more personalized immunosuppressive treatment might prevent over- and under-immunosuppression with risk of rejection, infection and PTLD. Furthermore the Annelloma of the donor and recipient is investigated to study the transmission of the virus from donor to recipient.Antonia Bouts
Family Mental healthThis research line aims to improve family-focused approaches to mental health care by implementing effective strategies and developing and testing improved strategies. Professionals in child and adolescent mental health care services and adult mental health care services receive guidelines they can put into practice in order to give families optimal care. Questionnaires, focus groups and interviews are used to gather insights from professionals as well as information on effectivity from parents and their children. Longitudinal databases that include genetic data are used to improve the identification of families that are vulnerable for a less favourable course in order to provide more intense treatments to those in highest need.

Paediatric IBD with focus on nutritional therapyI am a pediatrician and epidemiologist. I discovered that Group B Streptococcus (GBS) disease, the most common cause of sepsis and meningitis in infants, is increasing and showed that current prevention guidelines are inadequate. The goal of my research is to develop effective and targeted prevention approaches for sepsis and meningitis in infants. I therefore started the NOGBS prospective nationwide cohort study that investigates GBS colonization and disease. NOGBS has already collected clinical data, blood and bacterial isolates from cases with GBS and E. coli (>500) and controls (>1000).

In collaboration with the Wellcome Sanger Institute, I am identifying new diagnostic targets to improve GBS prevention. I am using a unique dataset that combines clinical data, long-term surveillance data and bacterial sequencing of invasive and colonizing bacteria. We are currently performing the largest GBS bacterial genome-wide association study to date.
Outcome data, essential for cost-effectiveness research, was lacking for GBS disease. I therefore started a collaboration that established long-term outcomes for nearly 3000 Dutch and Danish infants with GBS disease.
Vaccination against GBS during pregnancy is a promising new prevention strategy. NOGBS joined the international PREPARE consortium to establish immune correlates of protection against GBS disease. These correlates will be used in clinical trials.

Stem cell therapy for kidney diseaseNEOGRAFT is an innovative ‘high-risk – high gain’ translational project, which tackles a global problem of chronic kidney diseases by establishing a novel type of cell therapy, using as source the neonatal kidney stem/progenitor cells (nKSPC). The ultimate goal of the project is to:
i. reconditio kidney grafts prior to transplantation and extend number of kidneys suitable for transplantation in a growing population of patients on a transplantation waiting list;
ii. regenerate kidneys affected by chronic kidney diseases.

For doing that, nKSPC need to be characterized in-depth to gain fundamental insights in developmental, immunomodulatory and regenerative potential of the cells. Additionally, in this project we make the first steps towards the establishment of a potent and safe cell source suited for consequent clinical trials.

New therapy for cystinosisCystinosis is a genetic disorder affecting kidney function due to cystine accumulation. Current treatment with cysteamine slows progression but has many side effects. Our research suggests cystinosis-affected cells struggle to use cysteine for energy production. This project aims to stimulate this metabolic pathway using vitamins (vitamin B5 or vitamin B3) to improve energy metabolism in kidney cells. Using patient-derived cell models and advanced metabolic analysis, we study cystine and cysteine dynamics. Since vitamins are already available, our findings could quickly translate into improved patient treatment.

Global Pediatric OncologyGlobally, each year more than 400,000 children are confronted with cancer. While the far majority (>80%) of children lives in so-called low- and middle income countries (LMIC), their chance of cure typically is 20% or less. This is the opposite for children with cancer in high-income countries (HIC): less than 20% of all children reside there with >80% chance of cure. This research program is aimed to help bridging this gap and fits nicely in the WHO Global Initiative on Childhood Cancer. This initiative aims to achieve at least 60% cure for children with cancer worldwide. Important pillars in this program are datamanagement, better care including anticancer treatment and supportive care, capacity building, research and advocacy.Gertjan Kaspers
Childhood acute myeloid leukemiaChildren with acute myeloid leukemia (AML) currently have a cure rate of 80% in high-income countries such as The Netherlands. However, that comes with a cost in terms of significant morbidity during treatment and frequent late effects after completion of therapy. In low- and middle-income countries, survival rates are typically well below 30%. In other words, treatment must further improve all over the world. ImportantGertjan Kaspers
Neuroscientic outcome measurementThis research line aims to determine the impact of disease and treatment on the brain of children and young adults. The work focuses on the development and application of neuroscientific outcome measurements in typically developing and clinical groups, assessing neurocognitive functioning in children and adults (e.g. the in-house developed ‘Emma Toolbox for Neurocognitive Functioning’), advanced analysis of neurocognitive test performance (e.g. neurocognitive networks), structural and functional brain networks (e.g. DTI resting-state fMRI), and early neurocognitive functioning in babies and infants (e.g. eye-tracking).Jaap Oosterlaan
Clinical outcome prediction for precision medicineThis research line is aimed at better prediction of patient outcome, contributing to the transition towards precision medicine by improving clinical outcome prediction.

Data-driven health care innovationThis research line aims to innovate health care using structured clinical data, by integrating care, evaluation and scientific research using structured care paths. This work is focused on the development of structured multidisciplinary clinical (follow-up) programs that make use of structured electronic clinical registration and integrate with other clinical data sources (e.g. medical devices, patient reported outcome measurements). Consequently, the structured clinical data flows into rich and ever-accumulating databases that are re-used for care evaluation and scientific research aimed at data-driven care innovation. The Emma Children's Hospital Follow Me program is the blueprint for this work.Jaap Oosterlaan
Pediatric acute lung injury and respiratory supportThis research line aims to determine the impact and treatment of acute lung injury in critically ill children. The work focuses on pathophysiological mechanisms and epidemiology of severe viral respiratory infections and ARDS, childhood respiratory trajectories, the effectiveness of various respiratory support modalities (e.g. mechanical ventilation and non-invasive ventilation), potential adverse effects of treatment (e.g. ventilator- and hyperoxia-induced lung injury), and opportunities for optimization of treatment (e.g. ventilation mask personalization).Jeroen Hutten
Control of breathing in preterm infantsThe research focuses on monitoring respiration in preterm infants using transcutaneous electromyography of the diaphragm (dEMG) and exploring treatments for apnea in preterm infants. This includes both bench studies and clinical trials. Over the past few years, dEMG has been validated as a reliable method for cardiorespiratory monitoring. Further investigations are underway to determine whether dEMG can be utilized to synchronize spontaneous breathing in preterm infants with ventilators. Additionally, the research examines the effects of hypoxia resulting from apnea and assesses the safety and efficacy of doxapram as a potential treatment for apnea in preterm infants.

Paediatric IBD with focus on nutritional therapyThe increasing incidence of Crohn’s disease causes considerable morbidity and poses challenges for our health care due to costs of therapy/hospitalisation/surgery. We and others have shown in randomized trials that dietary self-management using the Crohn’s exclusion diet (CDED) can induce remission in children and adults, increase quality of life and reduce the need for immune-suppressing medication. Our research programme assesses biomarkers/multi-omics and novel technology (including heart-rate variability) to improve intestinal healing with dietary therapy. Analysis of HRV-data of patients from disease to remission and during maintenance of remission, will enable integration of biomarkers (CRP/calprotectin) and immune-phenotyping together with multi-omics analyses (epigenetics, microbiome, metabolome). To date, disease management is guided by markers of inflammation in blood and feces together with return of symptoms, which are late signs. Our programme hopes to facilitate the development of non-invasive bio-signatures to help patients improve self-management. In addition to this novel investigator-initiated research programme, we also participate in several industry-sponsored clinical trials and collaborate with other centers in Europe and Canada on IBD-related research projects with other members of the ESPGHAN-Porto IBD group.Johan van Limbergen

Pediatric trombosisThe research line focuses on two topics: anticoagulation in children and long-term outcomes after thrombosis.
In our anticoagulation research, we strive to determine the optimal dosage for children of, among other things, low-molecular-weight heparin, with the fewest side effects. We also investigate how to treat thrombosis as optimally as possible. This way, we aim to ensure that children have the best possible outcome from their thrombosis.
In our long-term outcome studies, we examine the complications children develop with different types of thrombosis. A pulmonary embolism causes very different symptoms than a thrombosis in the leg. By accurately identifying the symptoms children experience after their thrombosis, and the risk factors for developing them, we can tailor follow-up to the anticipated problems for each child.

The work focuses on pathophysiological mechanisms and epidemiology of severe viral respiratory infections and ARDS, childhood respiratory trajectories, the effectiveness of various respiratory support modalities (e.g. mechanical ventilation and non-invasive ventilation), potential adverse effects of treatment (e.g. ventilator- and hyperoxia-induced lung injury), and opportunities for optimization of treatment (e.g. ventilation mask personalization).Reinout Bem
Metabolism and Metabolic Brain DisordersThis research line aims to identify new metabolic disorders and resolve the pathophysiology of different IMDs based on the detailed knowledge of metabolism with the ultimate goal to develop strategies for the treatment of patients affected by different IMDs. Particular emphasis is focused on Hyperoxaluria together with Dr. Sander Garrelfs, Prof. dr. Jaap Groothoff c.s., Gyrate Atrophy together with Prof.dr. Clara van Karnebeek c.s. among others IMDs.Ronald Wanders
Evaluation of hormonal treatment in transgender adolescentsThis research line aims to evaluate treatment trajectories and the efficacy and safety of endocrine treatment for transgender adolescents. A wide range of treatment outcomes has been or is being assessed including continuation/discontinuation of endocrine treatment, growth/adult height, development of desired sex characteristics (such as breast development, voice change), body image, sexual function, safety data such as changes in bone mineral density, and outcomes with regard to fertility/fertility preservation. Research is performed in close collaboration with internist-endocrinologists, psychologists, psychiatrists, gynaecologists, surgeons and ethicists.Sabina Hannema
Improving care for children and adolescents with a difference of sex development (DSD)This research line focuses on evaluating outcomes in individuals with a difference of sex development (DSD) in order to improve care. Care pathways have been structured according to the Follow Me programme, allowing continuous data-driven health care innovation. Topics of interest include gonadal function and pathology and optimizing hormonal treatment to induce puberty.Sabina Hannema

Pediatric ImmunologyThis research line aims to determine the impact of immune dysfunction in genetically determined so-called “inborn errors of immunity (IEIs)” and various conditions of induced (acquired) innate or adaptive immune dysregulation. To these conditions, (auto)inflammatory and B-cell immune-mediated disorders (B-IMDs) are being focused on. In the realm of infection and inflammatory diseases in children we try to find an RNA- and/or protein-based signature to distinguish large categories of disease as a “super-CRP” in a large European consortium to categories to guide diagnostics and treatment in a faster and more certain fashion.

Generation P: Microbiome and pediatric gut healthThis research line aims to determine the impact of microbiome and metabolome on early gut health and health outcomes beyond infancy. The work focuses on the correlation between antibiotic exposure, feeding pattern and microbial colonization, related to gut health outcomes, including growth, neurocognitive outcome, asthma en alleries. Furthermore, this research line focused on the development of microbiota-based biomarkers for necrotizing enterocolitis and gut-derived neonatal sepsis.Tim de Meij
Microbiome and metabolome in pediatric IBD
Therapeutic drug monitoring in MTX
This research line aims to determine the impact of microbiome and metabolome on disease course in pediatric IBD and to predict therapy response. The work focuses on the correlation between gut microbes and metabolomics in de novo pediatric IBD. Furthermore, this research line focused on therapeutic drug monitoring in MTX and on cancer surveillance in pediatric IBD.Tim de Meij
DREAMS (Dutch REsearch in child and Adolescent Mental health)DREAMS is a collaboration between 4 child- and adolescent psychiatry centers in the Netherlands: Accare (Groningen), Karakter (Nijmegen), LUMC Curium (Leiden) en Levvel (Amsterdam). Together, DREAMS provides care for approximately 25.000 children per year (0-18 years old). The aim of DREAMS is to do large scale research into risk and protective factors of mental health problems, treatment effects, general wellbeing and long-term outcomes.

Bronchopulmonary dysplasiaThis research line investigate prediction, diagnosis, pathophysiology, prevention and treatment of bronchopulmonary dysplasia (BPD) in preterm infants. The work focuses on reducing the incidence and the burden of BPD in preterm infants by prevention, but also treatment in established BPD, as well as monitoring of the long term outcome of BPD.Wes Onland
Malnutrition in childhoodThis research line is grouped around the broad theme of undernutrition in children with an acute illness in low-resource settings (Low- and Middle-Income Countries). Vulnerable patient groups (cerebral palsy, severe acute malnutrition) are the focus of attention and triage (how to recognise illness in an early stage?) and risk prediction (can we identify a poor outcome in advance?) are main areas of interest. Data collection is done outside of Europe and done with academic partner institutions abroad (Malawi, Yemen, Kenia,Bangladesh).Wieger Voskuijl
Familiaire HypercholesterolemieOur research focuses on the treatment and outcomes of children with Familial Hypercholesterolemia (FH). FH is a genetic disorder that leads to high cholesterol levels, increasing the risk of cardiovascular disease from a young age. Our research aims to understand how early intervention can improve long-term health outcomes for individuals with FH. We are investigating various treatment strategies, monitoring their effects on cholesterol levels, and evaluating potential impacts on the prevention of heart disease. By closely tracking both short-term and long-term results, we hope to enhance the understanding of atherosclerosis in FH and develop optimized treatment protocols. Ultimately, our goal is to improve the quality of life and lifespan for children diagnosed with this condition. Furthermore we investigate the role of high Lp(a) in childhood.Willemijn Corpeleijn
