Pediatric Endocrinology

Building Your Care Team and Daily Management

At a Glance

Children with DEND syndrome need coordinated diabetes, neurology, genetics, and therapy care, plus glucose, feeding, and seizure planning. Families should keep records, follow a written sick-day plan, and know when severe low blood sugar, seizures, or dehydration require emergency help.

Managing DEND or iDEND syndrome is a long-term journey that requires a dedicated team and careful daily routines. Because the condition is so rare, your role as an important advocate and partner is vital while making clear that care coordination is a responsibility of the clinical team as well. By building a strong team and keeping detailed records, you ensure that every specialist has the information they need to provide the best care ^[1]^[2].

Building Your Expert Team

Because DEND affects both the pancreas and the brain, your child needs a multidisciplinary team—a group of specialists who work together ^[1]. This team should include:

Pediatric Endocrinologist: The lead for managing diabetes and the transition to sulfonylureas ^[2].
Pediatric Neurologist: To monitor brain development, manage epilepsy, and track muscle tone ^[3].
Medical Geneticist: To interpret the genetic report and provide counseling for your family ^[4].
Therapy Specialists: Physical (PT), Occupational (OT), and Speech-Language (SLP) therapists to support motor skills and developmental milestones ^[1]^[3].
Diabetes Educator & Nutritionist: To help you master the technology and ensure your child gets the nutrition they need for growth ^[2].

Preparing for Your First Appointment

When you meet a new specialist, having the right “artifacts” (physical records) can save time and prevent errors. Bring a folder containing:

The Molecular Genetic Test Report: The single most important document for determining treatment ^[3].
Glucose Logs: Printed reports from your Continuous Glucose Monitor (CGM) or a handwritten log of finger-stick readings ^[5].
Medication List: The exact doses and times for all medications, including insulin and sulfonylureas.
Growth Charts: Records of your child’s weight and height over time ^[6].

Daily Management and Safety

Daily life with DEND involves balancing medication, feeding, and monitoring. Most families use a CGM to watch blood sugar trends, but it is important to remember that CGM sensors can be less accurate during rapid changes or very low readings in infants ^[7]. Always treat a symptomatic or clearly low reading immediately, even if waiting for a finger-stick confirmation, unless the treating team has given a different plan ^[7].

Feeding is Safety

Sulfonylureas work by helping the pancreas release insulin. If your child does not eat enough, or if they vomit their meal, the medication may still cause their body to release insulin, leading to low blood sugar ^[8]. Never skip a feeding while on high-dose sulfonylureas without following your doctor’s “sick day” plan ^[9]. Do not force feeds or oral medication into a vomiting, lethargic, or unsafe-to-swallow child. Contact the diabetes team for urgent clinical advice and follow written instructions for glucose, ketones, and medication.

Red Flags: When to Seek Emergency Care

While side effects from sulfonylureas are often mild (such as temporary stomach upset), you must be able to recognize critical “red flags” that require immediate medical attention ^[6]^[10].

Sign	What it Looks Like	Action
Severe Hypoglycemia	Extreme sleepiness, inability to wake up, shaking, sweating, or a seizure when blood sugar is low ^[10]^[11].	DO NOT give anything by mouth to an unconscious or seizing child (aspiration risk). If awake and swallowing, give fast-acting carbs. If unconscious/seizing, administer prescribed glucagon and call 911 immediately.
Uncontrolled Seizures	A seizure lasting 5 minutes or more, repeated seizures without recovery, or breathing difficulty ^[12]^[13].	Call 911 (emergency services). Use rescue medication only as prescribed by your neurologist.
Diabetic Ketoacidosis (DKA) Signs	Vomiting with deep/rapid breathing, altered consciousness, severe dehydration, or significant ketones ^[14]^[15].	Call 911 or go to the nearest Emergency Room immediately.

Consistent monitoring and a clear communication channel with your team are your best defenses against these emergencies ^[1]. Many families find it helpful to keep a “Go Bag” packed with emergency glucose, a glucometer, and a copy of their child’s emergency medical plan.

Common questions in this guide

What specialists should be on my child’s DEND syndrome care team?

Care is usually coordinated across a pediatric endocrinologist, pediatric neurologist, medical geneticist, and therapy specialists such as physical, occupational, and speech-language therapists. A diabetes educator and nutritionist can also help with glucose technology, medication routines, feeding, and growth.

What records should I bring to a DEND syndrome appointment?

Bring the molecular genetic test report, recent continuous glucose monitor or finger-stick logs, a complete medication list with doses and times, and growth charts. These records help specialists understand treatment, glucose patterns, development, and growth without relying on memory.

What should I do if my child vomits or will not eat after taking a sulfonylurea?

Sulfonylureas can continue to make the pancreas release insulin even when a child eats too little, so low blood sugar can develop. Follow the written sick-day plan and contact the diabetes team urgently for instructions about food, glucose, ketones, and medication; do not force food or oral medicine if the child is vomiting, very sleepy, or cannot swallow safely.

How do I recognize severe low blood sugar in a child with DEND syndrome?

Warning signs include extreme sleepiness, inability to wake, shaking, sweating, or a seizure with a low glucose reading. If the child is awake and can swallow, follow the emergency plan for fast-acting carbohydrate; never give anything by mouth to an unconscious or seizing child, use prescribed glucagon, and call emergency services.

When does a seizure or diabetes symptom require emergency care?

Call emergency services for a seizure lasting 5 minutes or longer, repeated seizures without recovery, or breathing difficulty. Vomiting with deep or rapid breathing, altered consciousness, severe dehydration, or significant ketones can signal diabetic ketoacidosis and require immediate emergency care.

How can I prepare other caregivers and school staff for DEND syndrome emergencies?

Give caregivers a written emergency plan that lists glucose thresholds, medication instructions, seizure steps, and emergency contacts, and ask the clinical team for an emergency letter. Keep a go bag with glucose, a meter, ketone strips, and the child’s plan, and make sure caregivers know the hypoglycemia and feeding risks.
