Useful Progress?
A recent research paper in Science reported intriguing chemical findings that seemed to point a finger at some form of complement dysregulation as a potential disease marker for long COVID. Unfortunately, some critics have pointed out that this entire study may be invalid or irrelevant because the New York cohort was recruited in 2020, before vaccines were available. The Zurich cohort was recruited up until April 2021, so some may have been vaccinated.
Then this news organization came along in early January 2024 with an article about COVID causing not only more than a million American deaths but also more than 5000 deaths from long COVID. We physicians don’t really know what long COVID even is, but we have to sign death certificates blaming thousands of deaths on it anyway? And rolling back the clock to 2020: Are patients dying from COVID or with COVID, according to death certificates?Now, armed with the knowledge that “documented serious post–COVID-19 conditions include cardiovascular, pulmonary, neurological, renal, endocrine, hematological, and gastrointestinal complications, as well as death,” CDC has published clear and fairly concise instructions on how to address post-acute COVID sequelae on death certificates.
In late January, this news organization painted a hopeful picture by naming four phenotypes of long COVID, suggesting that such divisions might further our understanding, including prognosis, and even therapy for this condition. Among the clinical phenotypes of (1) chronic fatigue–like syndrome, headache, and memory loss; (2) respiratory syndrome (which includes cough and difficulty breathing); (3) chronic pain; and (4) neurosensorial syndrome (which causes an altered sense of taste and smell), overlap is clearly possible but isn›t addressed.
I see these recent developments as needed and useful progress, but we are still left with…not much. So, when you tell me that you do or do not have long COVID, I will say to you, “How do you know?”
I also say: She/he/they who know COVID know medicine.
