ALPINE, Utah, Oct. 30, 2020 /PRNewswire/ — Research reveals that COVID-19 patients have severe damage to microcirculation and the endothelial glycocalyx. The data in a newly released study clearly show severe reduction of microcirculation and the endothelial glycocalyx in patients with COVID-19 and underscores the importance of healthy microcirculation and capillaries. This study was possible because of GlycoCheck, a new groundbreaking medical device from Microvascular Health Solutions.
The study’s finding has fueled the hypothesis that COVID-19 is actually a vascular illness and that systemic leakiness and impairment of the endothelial glycocalyx might play a central role in the development of acute respiratory distress syndrome (ARDS) and multi-organ failure.
Capillaries are lined with a gel-like lining called the endothelial glycocalyx. When they are in good health the glycocalyx enables delivery of essential oxygen and nutrients to all vital organs. When microcirculation is severely impaired, as is the case for critically ill COVID-19 patients, lung function is significantly reduced, and mechanical ventilation is required for them to breathe.
The study was overseen by University Hospital Munster in Germany and compared three groups:
The study reveals:
With a large percentage of the smallest capillaries having been severely damaged, oxygen cannot be transported from the lungs to the rest of the body.
GlycoCheck testing is non-invasive. A video microscope camera is placed under the tongue where microvessels are representative of the entire body. In minutes, 100,000 vessels are measured, with 1,000 measurements calculated per vessel. There are over 100 million calculations from the test.
The GlycoCheck test measures the interaction of red blood cells with the surface of the endothelial glycocalyx, expressed as the perfused boundary region (PBR). Increases in PBR reflect damage to the glycocalyx. This parameter was developed by Dr. Hans Vink, PhD, a glycocalyx research pioneer who has studied the glycocalyx for more than three decades. Dr. Vink considers PBR to be the “canary in the coal mine” that reveals if the glycocalyx has become thin and damaged.
GlycoCheck combines the PBR measurement with density of capillaries, and capillary recruitment capacity, which is how capillary density increases at higher levels of blood flow. Together, these three measurements analyze microvascular health and objectively report a single systemic MicroVascular Health Score™.
The glycocalyx becomes damaged because of risk factors such as aging, genetics, obesity, stress, pollution, smoking, and vaping. Researchers in 90 hospitals worldwide use GlycoCheck to link a damaged glycocalyx with heart disease, kidney disease, stroke, hypertension, diabetes, and other conditions. With this study, COVID-19 can also be linked to a severely damaged glycocalyx.
