Why do patients with long COVID have such a wide array of symptoms affecting so many bodily systems? That bedeviling question is the focus of this episode of Raise the Line featuring Dr. Resia Pretorius, head of the Department of Physiological Sciences at Stellenbosch University in South Africa and a renowned researcher in coagulation. “The underlying concept of what is happening, in our minds, is that long COVID is a widespread vascular endotheliitis, which is driven by the presence of all sorts of inflammatory molecules in circulation,” she tells host Dr. Raven Baxter of the Cohen Center for Recovery from Complex Chronic Illnesses (CoRE). Because endothelial cells line blood vessels that travel to every part of the body, their impairment produces a range of symptoms. Dr. Pretorius and her research colleagues have discovered that “microclots” – abnormal proteins that prevent clots from breaking down – are another ingredient in the long COVID recipe due to their possible role in reducing oxygen flow to the brain and other organs. Because of their unusual structure, microclots are not detected by customary blood tests, leading Dr. Pretorius to add her voice to the chorus of stakeholders calling for the development of new diagnostic tests and additional treatments. “We need a concerted effort for trials. We need FDA approval for the laboratory test that we developed. I’m confident we will get it done, but it will take time, which is sad.” Tune in to learn about the possible causes of microclots, promising research on anticoagulation therapy and why long COVID is not a “checklist” disease, as our special series on post-acute infection syndromes continues.
