Congenital Hyperinsulinism International

Register now for the CHI Family Conference

CHI Family Conference at ESPE 2019: Register by August 30th!

On September 20-22, 2019, Congenital Hyperinsulinism International (CHI) in partnership with Kongenitaler Hyperinsulinismus e.V. and Lobby4Kids will hold the 2019 Congenital Hyperinsulinism Family Conference in Vienna, Austria. The conference will feature world-renowned physicians, researchers, and specialists who treat children with congenital hyperinsulinism (HI), as well as parent and patient advocacy leaders. There will be opportunities for HI families to meet and share their experiences with other HI families. The family conferences are a fantastic opportunity to learn more about all aspects of the condition and to meet and get to know members of the global HI community.

We are happy to announce that registration for the conference has been extended until August 30, 2019. Hotel room reservations at the Renaissance Wien are limited but still available through July 26, 2019. After July 26, we will confirm hotel room reservations on an as available basis.

CHI Announces HIHA Grant Award of $70,000

CHI's 2019 HIHA Grant has been awarded!

For immediate release: May 20, 2019

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 info@higlobalregistry.org.

The HI Global Registry Has Launched

Patient-Powered Research for a Brighter Future

Press Release: Glen Ridge, NJ, October 8, 2018 – The HI Global Registry will generate new insights into congenital hyperinsulinism (HI), drive new research for treatments and cures, and support the success of clinical trials.

“The HI Global Registry is a groundbreaking new global online research study powered by patients and their families, developed by CHI with partners around the world.” – Julie Raskin, CHI Executive Director

Congenital Hyperinsulinism International (CHI) is very excited to announce today’s launch of the HI Global Registry. The HI Global Registry provides a convenient online platform for the HI patient community to share their experiences of living with congenital hyperinsulinism (HI). By participating in this study, the patient community will help themselves and researchers better understand HI to advance better treatments, a potential cure, and more timely and accurate diagnoses. (scroll down to read more, or click here for a PDF of this press release. Click on the registry logo below to go directly to the Registry).

HI Global Registry


The HI Global Registry consists of a series of surveys with questions about health, treatment, development, and quality of life. People with HI or their parents or caregivers can participate from anywhere in the world. Participants will be able to view graphic representations of the responses of the greater HI global community to see how their personal experience fits into the greater whole.

“This is an exciting day. The HI Global Registry is the first global patient registry for those affected by HI. The Registry team has brought together patient representatives from around the world to work with international researchers and clinicians on the development of the Registry and today we are live. This patient-powered project will be a vital resource to better understand HI for years to come.” – Davelyn Eaves Hood, MD, MBA

The HI Global Registry has been developed and hosted on a platform built by the National Organization for Rare Disorders (NORD), the patient advocacy organization dedicated to individuals with rare diseases and the organizations that serve them.

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.
