Testing for Diabetes in Children

Diabetes mellitus can be a devastating illness, especially when it comes on suddenly in a child or adolescent. In young people it is usually so-called Type 1, or insulin-dependent diabetes, an autoimmune disease in which the immune system attacks the insulin-producing beta cells in the pancreas. The disease can have a major impact on the whole family, and sometimes people forget the way in which it can affect siblings whose needs often need to be subordinated to the needs of the newly diagnosed young person.

And here is an important point: even when it appears suddenly, the disease process may have been going on for some time before the clinical symptoms appear. By the time that blood glucose levels begin to rise, it usually implies that the damage to the insulin-producing cells in the pancreas has reached a critical point, and the chance of recovery is low. Anything that we can do to prevent the disease from progressing to the point of producing symptoms would be immensely helpful, and that starts with early recognition before the pancreatic damage has reached critical.

Although we now understand a great deal about the interplay of genetic, environmental and immunological factors that may lead to the illness, this knowledge has so far not helped us very much. There has been a tremendous need to try and identify the early stages of the disease, but that goal has been elusive.

In a study published in the Journal of Immunology researchers from the University of Queensland’s Diamantina Institute for Cancer, Immunology and Metabolic Medicine, are developing a simple test that may predict whether a child will develop Type 1 diabetes. They have identified a cellular pathway known as NF-kappa B that is activated in certain blood cells – monocytes and dendritic cells – of people with Type 1 diabetes.

In healthy people monocytes remain quiescent unless they are activated by an infection or other stressor. Then the NF-kappa B pathway gets activated.

In people with Type 1 diabetes things work the other way round: monocyte NF-kappa B was already activated in the blood, and when exposed to infection the pathway shut down. This tells us that there is a problem of immune control that may cause diabetes to develop in children. It is this monocyte abnormality that will hopefully form the basis of a diagnostic test.

This work is assuming more urgency since there are several trials of diabetes vaccines underway, and if successful, it may become possible to identify and intervene in children at risk of Type 1 diabetes before it occurs.

In addition, understanding why the immune system loses control before the disease starts should open up a number of new options for prevention and treatment.
