New study from King’s College London published in Nature Medicine reveals a new relationship between lipids and diseases impacting metabolism in children, which could serve as an early warning system for conditions like liver disease.
Using machines that test blood plasma in babies that already exist in hospitals, the researchers suggest this could help doctors spot early signs of disease in children quicker and help them access the right treatment.
The findings also contest the common idea that cholesterol is a leading cause of complications around obesity in children, identifying new lipid molecules which contribute to health risks like blood pressure but are not only correlated with a child’s weight.
Lipids have traditionally been thought to be fatty acids in the body, either good or bad types of cholesterol or triglycerides, fats found in the bloodstream that is the most common in the human body. Recent studies from the same group of scientists have suggested that the picture is more complex.
Using a technique associated with chemistry called mass spectrometry, current evidence puts the types of different lipid present in the body in the thousands, each with separate functions.
Taking a control sample of 1,300 children with obesity, the team assessed their lipids in blood. Afterwards 200 of them were put on the HOLBAEK-model for a year, a lifestyle intervention for people with obesity popular in Denmark.
Subsequent readings showed that amongst the intervention group, counts of lipids tied to diabetes risk, insulin resistance and blood pressure decreased, despite limited improvements in some children’s BMI.
Dr Cristina Legido-Quigley, a group leader in Systems Medicine at King’s College London, Head of Systems Medicine at the Steno Diabetes Centre Copenhagen (SDCC) and principal author, said: “For decades, scientists have relied on a classification system for lipids that have split them into good and bad cholesterol, but now with a simple blood test we can assess a much broader range of lipid molecules that could serve as vital early warning signs for illness. In the future, this has the potential to be an entirely new way to evaluate someone’s personal risk of disease and by studying how to change lipid molecules in the body, we could even prevent metabolic diseases like diabetes altogether.”
