Diabetes Complications Linked to Lower IQ in Children

Diabetic ketoacidosis (DKA) is linked to lower memory and IQ scores in children diagnosed with type 1 diabetes. It is vital to prevent DKA in children with type 1 diabetes and timely diagnose DKA development.

Diabetic ketoacidosis (DKA) is linked to lower IQ scores and worse memory in children with type 1 diabetes, according to a new study by UC Davis Health researchers.

The study is published in the journal Diabetes Care. It is the first large-scale study that differentiated between DKA’s impact on children with a new diagnosis of type 1 diabetes and children with a previous diagnosis.

Type 1 Diabetes- Protecting Beta Cells Against Stress may Help
Beta cells in the pancreas that lack the protein renalase provoke a diminished response from immune system. The survive the autoimmune killing which may guard against type 1 diabetes. An existing drug boosts survival for insulin-producing cells under autoimmune attack.

Diabetic ketoacidosis (DKA) occurs when diabetes is undiagnosed or poorly managed. Acidic substances called ketones build up to dangerous levels as blood sugar level gets really high.

Early signs of DKA are:

Excessive thirst
Frequent urination
Nausea
Abdominal pain
Weakness
Confusion

The study consisted of 376 children with type 1 diabetes with no history of DKA. The study also included 758 children with type 1 diabetes and a history of DKA.

Rotavirus Vaccine May Protect Children Against Type 1 Diabetes
Babies who received the recommended dose of rotavirus vaccine are not only protected against stomach flu, but also are protected from developing type 1 diabetes when compared to unvaccinated or partially vaccinated infants.

These children were of the ages 6-18 years. They were participating in a DKA clinical trial at the Pediatric Emergency Care Applied Research Network (PECARN) sites.

One severe DKA episode can hurt memory and IQ

Metformin can Now Prevent Heart Disease in Type 1 Diabetes
Heart disease can be prevented in Type 1 diabetes by using the drug metformin, which is used in Type 2 diabetes. The underlying mechanism involves the modulation of the levels of microRNAs by metformin treatment.

The researchers found lower long-term memory in children who were newly diagnosed with type 1 diabetes with moderate to severe DKA.

Greater severity of DKA was also associated with lower IQ in these children.

Artificial Pancreas �Safe� for Treating Type 1 Diabetes
An artificial pancreas device systems is a smartphone-sized device that helps measure blood sugar levels and is found to be a safe and effective treatment approach for people with type 1 diabetes.

Children with a previous diagnosis of DKA showed lower performance compared with children with new-onset in measures of memory and IQ. This finding suggests that cognitive deficits may worsen over time.

Complex associations of DKA severity, socioeconomic status and glycemic control was observed among previously diagnosed patients.

The researchers found that patients with repeated DKA exposure and poorly controlled type 1 diabetes are at risk of cognitive deficits.

"The results from the study emphasize the importance of prevention of DKA in children with known type 1 diabetes and of timely diagnosis during new-onset before the development of DKA," said Glaser, professor of pediatrics at UC Davis Health and senior author of the study.

"There is an opportunity to prevent DKA with proper management of the glucose level in the blood," he added.
