The CHI Centers of Excellence (COE) Program

CHI Center of ExcellenceWe are thrilled to announce the launch of the Congenital Hyperinsulinism International (CHI) Hyperinsulinism Centers of Excellence (COE) Program. The CHI COE Program will designate specialist facilities providing the highest quality of care for hyperinsulinism (HI) patients and their families around the world.

Every year, around the globe, thousands of babies are born with HI. They need appropriate and expert care to reduce the risk of brain damage and death and to ensure proper management of their disease for the best possible quality of life, as do all children and adults living with HI.

There are some superb institutions known for providing excellent HI care and participating in groundbreaking research, yet until now there has not been a review process or certificate awarded to institutions for the care of those with HI.

CHI receives a Rare As One Network Grant

Chan Zuckerberg Rare As One

Congenital Hyperinsulinism International is thrilled and humbled to announce that we are one of 30 rare disease organizations to receive a Rare As One Network grant of $450,000, distributed over two years, from the Chan Zuckerberg Initiative. This grant will allow us to work with the patient and scientific community to create a patient-led sustainable, lasting structure to prioritize and execute an international research agenda to better understand congenital hyperinsulinism (HI), identify new ways to improve the lives of those living with HI, reduce the incidence of irreversible brain damage, detect the genetic causes of HI types not currently known; and to find cures for each and every type of HI. Over the next few months we will learn much more about the resources available to build the network. We will be in contact with our CHI family partners and the scientific and medical community about collaborating on this exciting project.

CHI Announces HIHA Grant Award of $70,000

CHI's 2019 HIHA Grant has been awarded!

Glen Ridge, NJ, May 20, 2019 – Congenital Hyperinsulinism International (CHI) is thrilled to announce the award of $70,000.00 for a one-year pilot grant to Dr. Amanda Ackermann at the Children’s Hospital of Philadelphia. With this grant funding, Dr. Ackermann will create a Novel Mouse Model to Investigate Pathophysiology of Hyperinsulinism/Hyperammonemia Syndrome (HIHA). The understanding that will come from creating and studying this mouse model is needed to develop treatments for high blood ammonia levels, seizures, and neurodevelopmental differences caused by HIHA.

The grant was competitively bid internationally, and Dr. Ackermann’s project was selected after a careful review of applications by an expert review panel made up of renowned endocrinologists and family members of patients. The committee carefully evaluated the applications, which were all excellent.

“I appreciate the focus and dedication to addressing the neurological effects in patients with HIHA. As a parent with a (now adult) child with HIHA, I am passionate about finding alternative treatments for HIHA. Other therapies are needed, and I strongly feel this this researcher is acutely aware of this need.”
– Dina Tallis, EdD, Parent Reviewer of applications.

“The investigator is highly qualified, well trained and in an excellent position to accomplish this project. In my opinion, this project is very appropriate for pilot funding in that it aims at developing a new animal model for this disease that will then be made available to the entire research community for further study of all aspects of this disease. This will be a very valuable resource whose overall impact will extend far beyond this specific grant proposal.”
– Benjamin Glaser, MD, Professor Emeritus, Hadassah-Hebrew University, Expert Endocrinologist Reviewer of applications.

HI Global Registry 1st Study Report Now Available

The HI Global Registry (HIGR) is the first global patient-powered congenital hyperinsulinism (HI) patient registry. Many years in the making, HIGR launched on October 8, 2018. What follows is an initial report from the HIGR investigators including an introduction to the research project and an early glimpse of data from it. While the first annual report by investigators is not planned until early 2020, the intent of sharing these early findings is to further engage stakeholders in HIGR’s work, better inform the preparation and data analysis of the HIGR annual reporting cycle, and encourage full and robust study participation from all potential study participants. As participation grows, the pool of HI data will become increasingly more significant.

The investigators openly invite comments and questions about the report and welcome ideas for engaging all key HI stakeholders. Broad and robust participation from all members of the HI community will certainly serve to strengthen HIGR. The HIGR team can be contacted at

About HI

HI is a life-threatening genetic disorder that causes severe low blood sugar. In most countries the estimated incidence of HI is approximately 1/25,000 to 1/50,000 births. For those with HI the beta cells of the pancreas secrete too much insulin in an unregulated manner. Excess insulin causes hypoglycemia. Prolonged or severe hypoglycemia can cause seizures, permanent brain damage or death, if left untreated. Due to the dangers of hypoglycemia, HI requires timely diagnosis.

About CHI

CHI, a 501(c)3, is a lifeline to those born with congenital hyperinsulinism (HI) and their families. CHI is the global organization dedicated to supporting children and adults born with HI. CHI is a leading source of funding for research for better treatments and cures, and the foremost advocate for increased
awareness and better medical protocols for HI to reduce preventable brain damage and death from prolonged hypoglycemia.
