Quantifying Inflammation
Patients with type 2 diabetes have about twice the risk for a cardiovascular event associated with atherosclerosis, such as a heart attack or stroke, during their lifetimes. “Predicting these complications in diabetic patients is usually very difficult,” Dr. Venteclef told this news organization.
“They are strongly associated with inflammation in these patients. Therefore, we sought to quantify this inflammation in the blood.” To do this, his team focused on monocytes, a category of white blood cells circulating in the blood. They measured the blood concentration of monocytes and the subtypes present in patients with type 2 diabetes.
The results were published in Circulation Research.
Dysfunctional Monocytes
The team worked with three cohorts of patients. The first, named AngioSafe-2, consisting of 672 patients with type 2 diabetes, was recruited from the diabetology departments of Lariboisière and Bichat Claude Bernard hospitals in France. This cohort allowed researchers to demonstrate that the higher the number of circulating monocytes, the greater the risk for cardiovascular events, independent of age and duration of diabetes. This observation was confirmed through a second cohort, GLUTADIAB, that comprised 279 patients with type 2 diabetes. Scientists complemented their work with molecular analysis of circulating monocytes in these two cohorts, which revealed certain predominant monocyte subtypes in patients with type 2 diabetes at high cardiovascular risk. “These monocytes are dysfunctional because they have a mitochondrial problem,” Dr. Venteclef explained.
To better understand how these results could be used to predict cardiovascular risk, the team collaborated with colleagues from the University Hospital of Nantes on a cohort called SURDIAGENE, which included 757 patients with type 2 diabetes. “We conducted a longitudinal study by following these patients for 10 years and quantifying cardiovascular events and deaths,” said Dr. Venteclef. Circulating monocyte levels were correlated with the occurrence of heart attacks or strokes. The researchers observed that patients with type 2 diabetes with a monocyte count above a certain threshold (0.5 × 109/L) had a five- to seven-times higher risk for cardiovascular events over 10 years than those with a monocyte count below this threshold.
A patent was filed at the end of 2023 to protect this discovery. “Our next step is to develop a sensor to quantify monocytes more easily and avoid blood draws,” said Dr. Venteclef. “As part of a European project, we will also launch a trial with an anti-inflammatory drug in diabetics, with the hope of interrupting the inflammatory trajectory and preventing complications.”
