The prevalence of diabetes mellitus has been increasing exponentially over the last decade, and the disease is rapidly becoming a global problem. Current estimates suggest that almost 25,000 people suffer from diabetes in Luxembourg (i.e. about 6% of the adult population between 20 and 79 years of age).

Sadly, this number is projected to further increase. Indeed, international diabetes experts predict that, in the absence of radical change, 592 million people will live with diabetes by 2035. This constitutes 10% of the global population. Diabetes represents a daily burden on the patients who have to scrupulously watch their diets, monitor their blood sugar levels and administer insulin injections. The disease can also lead to serious complications affecting the eyes, heart, kidneys and feet and is estimated to cause 11% of deaths in Europe. In addition, the increasing number of patients means that diabetes is becoming a growing burden on healthcare systems. In fact, in Germany, about 10% of all healthcare costs are spent on diabetes treatment and care.

Discovering the underlying causes

There are three different forms of diabetes:

  1. type I diabetes, which is due to the pancreas’s failure to produce insulin;
  2. type II diabetes, where the patient’s cells have stopped responding properly to insulin;
  3. diabetes in pregnant women, called gestational diabetes.

While it is clear that both genetic predisposition and environmental factors play important roles in the development of diabetes, many of the exact mechanisms underlying its development are still unknown. To improve the understanding of diabetes and identify new therapeutic and diagnostic approaches, we currently support several diabetes projects.

Studying the role of bacteria

In 2016 one of the first projects initiated by the Personalised Medicine Consortium achieved a major breakthrough in diabetes research. 60 donors were recruited for this study, including families with a history of type 1 diabetes, with the help of Dr de Beaufort (CHL/LCSB) and the Clinical and Epidemiological Investigation Center at the LIH. By analysing the stool samples collected and processed by the biobank, researchers from the LCSB discovered clear differences in the way bacteria function in the gut of people with and without diabetes.

A second long-term project is ongoing. By documenting the development and evolution of bacteria from birth, scientists try to figure out how the bacterial populations in babies might influence the onset of diabetes later in life. For this study, stool samples of healthy new-borns and new-borns that are at increased risk of developing diabetes as adults due to known risk factors such as low birth weight will be collected and processed by the biobank before reaching researchers’ laboratories.

Identifying new therapeutic targets

For another collaboration with the Otto von Guericke University of Magdeburg in Germany and the LCSB, we collect, process and store fat tissue and purified white blood cell samples from patients that display multiple risk factors for developing heart disease, stroke or diabetes. This study aims to determine how a lifestyle-mediated weight loss programme can affect a specific type of molecules inside cells, called microRNAs, in an effort to identify new therapeutic targets.
