Many people support in various ways medical research, which they perceive as urgent in view of the needs of various patient groups. But patients typically won’t benefit from research unless the results are translated into development of medical products.
Type 1 diabetes is an incurable disease that requires daily life-sustaining treatment and strict dietary rules. Disease onset usually occurs at an early age.
In Sweden, about 50 000 people have this form of diabetes and of these around 8 000 are children. In type 1 diabetes, the immune system attacks the insulin-producing cells. Without insulin the body cells cannot use glucose for energy, and the sugar level in the blood rises. Energy is recovered instead from fat and protein, which causes waste products that can cause diabetic coma and attacks on vital organs.
Today, diabetes is treated with daily insulin injections, or by using an insulin pump. This requires continuous measurement of blood sugar levels, as incorrect doses of insulin entails risks and can be life-threatening. It is not easy to live with diabetes.
An alternative treatment, which is still at the research stage, is to generate new insulin-producing cells using human embryonic stem cells. The insulin-producing cells detect blood sugar levels and regulate the secretion of insulin. In order not to be attacked by the immune system, the transplanted cells are encapsulated in a protective material. It may become easier to live with diabetes.
But research alone doesn’t treat diabetes. Encapsulated insulin-producing cells need to be produced and made available also to patients; not only to research participants.
