Top reference center for optimal care of children with growth disorders, with a leading role in clinical, fundamental and translational research in focus areas Prader Willi Syndrome, SGA, Silver Russell Syndrome, non-acquired growth hormone (GH)-IGF-I pathway disorders and GH resistance, in collaboration with partners in Erasmus MC and national and international researchers.
Includes the NFU accredited Dutch Expert Center for Prader Willi Syndrome (PWS) and Expert Center for Rare Growth Disorders, and EU Rare Growth Disorder Network in the European Rare Endocrine Network (Endo ERN)

Our ACE is involved in the education of Ba and MSc students, specialists in training, pediatric nurses, PhDs and postgraduate training. We developed a dedicated e-learning program with different levels, which is used in Erasmus MC to support the education of Ba and MSc students, pediatricians in training and PhDs. It is also used in the postgraduate training by our ACE.
The e-learning program has been approved by the European Society of Pediatric Endocrinology (ESPE) and is now worldwide available for (fellow) pediatric endocrinologists via ESPE website. We also designed a serious game allowing medical students, physician assistants, nurses, general practitioners, internists and endocrinologists to improve their endocrine knowledge. Because the game can be played at different levels, it is suitable for different audiences. For endocrinologists, for example, this game can replace a workshop during a conference. Our serious game provides an innovative way of learning, where knowledge is combined with humor and excitement; an ideal way to reach the target audience. We did not receive a formal feedback such as SET Q, visitation of audit report. Our ACE has on average one international student and one international PhD student (recently Spain, UK, Brasil, Latvia, now request from Chili)
Societal Relevance to Research, Education and Patient Care
Results of the many studies performed by our ACE are translated into clinical practice for patients and population health. Our ACE leads many scientific publications, develops of (inter)national guidelines, masterclasses and symposia for health care workers and for patients. Provides presentations during congresses, educational materials, newsletters for patients and updates on our websites www.groeienco.nl and www.praderwillisyndroom.nl.
Our ACE has developed the curriculum 'Growth disorders'' for Ba and MSc students and the innovative e-learning program on growth disorders which is nowadays used in Erasmus MC and worldwide. Our ACE is one of the world leading research centers for growth disorders, focused on pathophysiologic mechanisms and (epi)genetic research, innovative medicines, phase 2 and 3 multicenter clinical trials, long-term effects and cost-effectiveness. Based on our research data, the FDA and EMA have registered growth hormone treatment for patients with renal insufficiency, Turner syndrome and short stature after SGA birth.
Our research and subsequent clinical care regimen in children with PWS has changed the natural (morbid) course of PWS. Based on our recent data an application for GH registration for PWS adults will be filed. Our ACE contributes, mostly as leader, to (inter)national guidelines and development of care standards
Viability of Research, Education and Patient Care
Knowledge sharing in ACE occurs via
- Research meeting (1h/wk), with all researchers and (fellow) pediatric-endocrinologists- to discuss results, clinical implications and updates (guidelines and/or websites, newsletters), new initiatives and news from congresses/symposia, and via
- Clinical care meeting (2h/wk), with (fellow) pediatric-endocrinologists, pediatricians and biochemists in training, PhD fellows, head of Endocrine laboratory, clinical geneticist (1x/mo).
- 1x/2 mo meeting with the pediatricians of 18 hospitals of our regional network and
- 1x/3 months with pediatric-endocrinologists and fellows of South-West Netherlands and 1x/3 months with Dutch Advisory Board on GH therapy - to discuss difficult cases, give updates from our research and literature, discuss clinical implications of new insights.
During last 10 years, ACE generated 25 PhD doctorates (promotor Prof. A.C.S. Hokken-Koelega). All of them had >6 papers in high-ranking peer-reviewed international-journals, presented their data in >6 international congresses; 50% had international working experience (6 mo-2 yrs). Nineteen PhDs started an international career.
On average 8 PhD fellows working in the ACE. Monitoring/review 1-2 wkly by research teams, PhD fellows and supervisor, and annual reports. Bibliometric analysis not available. No doubt ACE belongs to world-top, based on 20 years of research. Hokken: 2012 ESPE Award for Scientific leadership
