When Type 1 Diabetes Triggers a Rare Blood Fat Crisis in Children

Triglycerides are a type of fat found in blood. While everyone has some triglycerides, severe hypertriglyceridemia means levels become dangerously high—above 11.3 mmol/L (or roughly 1,000 mg/dL). This rare condition can develop in children experiencing diabetic ketoacidosis (DKA), the life-threatening state where the body cannot produce enough insulin and blood becomes too acidic.

Until now, doctors have mostly learned about this complication through individual case reports rather than larger studies. A research team at Beijing Children's Hospital reviewed 10 years of patient records to better understand how often it happens and how to manage it.

The study identified 21 children with DKA complicated by severe hypertriglyceridemia. The typical age was around 11 years old, and about three-quarters of the children were 10 or older. The group included those with Type 1 diabetes, Type 2 diabetes, and unclassified diabetes.

What stood out: 17 of the 21 children were newly diagnosed with diabetes when they developed this complication. However, 4 children had pre-existing diabetes—and notably, 3 of those 4 had stopped taking insulin before being admitted to the hospital. This suggests that insulin therapy plays a key protective role.

Beyond the high triglycerides themselves, doctors observed acute pancreatitis (inflammation of the pancreas) in 7 of the 21 children—about one-third of the group. Pancreatitis is a painful and potentially serious complication that requires close monitoring and care.

All 21 children in the study received insulin therapy, which is the foundation of treatment for this condition. Insulin helps the body use blood sugar and can lower triglyceride levels.

In 7 of the cases, doctors also used plasmapheresis—a procedure that filters blood to remove excess fats and other substances. This group showed faster improvement in triglyceride levels compared to insulin alone. However, researchers noted that interpreting these results requires caution, since the children who received plasmapheresis may have had more severe disease to begin with. Plasmapheresis appears to be reserved for the most serious cases rather than used routinely.

This study is one of the largest on severe hypertriglyceridemia in children with diabetic ketoacidosis, filling a gap in medical knowledge. It shows that while rare, this complication deserves attention from doctors and families. Recognizing the signs of DKA—such as rapid breathing, fruity-smelling breath, and confusion—and seeking immediate emergency care remains critical. For those with known diabetes, consistent insulin use is essential, since stopping insulin appears to increase the risk of this dangerous complication.
