    Microvascular Capillary and Precapillary Cardiovascular Disturbances Strongly Interact to Severely Affect Tissue Perfusion and Mitochondrial Function

    Pre print Approved: 12 December 2023 Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a frequent, debilitating and still enigmatic disease. There is a broad overlap in the symptomatology of ME/CFS and the Post-COVID Syndrome (PCS). A fraction of the PCS patients develops the full...

    Endothelial dysfunction in Long-Covid measured by RVA correlates with symptom severity and inflammation

    Measurements and main results PCS patients exhibit persistent endothelial dysfunction (ED), as indicated by significantly lower venular flicker-induced dilation (vmax; 3.42% ± 1.77% vs. 4.64 % ± 2.59%; p = 0.02), narrower central retinal artery equivalent (CRAE; 178.1 [167.5 - 190.2] vs. 189.1...

    Sulodexide (Aterina) experiences

    Does anybody have any experiences with Sulodexide (Aterina) to address endothelial dysfunction, it’s sort of an oral version of heparin? (Of course this isn’t a cure, but possibly a drug to add on top of the usual stack). I've heard from his patients that Dr. Laubscher, who's the clinical...

    Serum of Post-COVID-19 Syndrome Patients with or without ME/CFS Differentially Affects Endothelial Cell Function In Vitro (Flaskamp et al, 2022)

    Abstract A proportion of COVID-19 reconvalescent patients develop post-COVID-19 syndrome (PCS) including a subgroup fulfilling diagnostic criteria of Myalgic encephalomyelitis/Chronic Fatigue Syndrome (PCS/CFS). Recently, endothelial dysfunction (ED) has been demonstrated in these patients, but...

    Endothelial dysfunction and altered endothelial biomarkers in patients with post-COVID-19 syndrome and chronic fatigue syndrome (ME/CFS)

    Abstract Background: Fatigue, exertion intolerance and post-exertional malaise are among the most frequent symptoms of Post-COVID Syndrome (PCS), with a subset of patients fulfilling criteria for Myalgic...

    Erectile Dysfunction as Dysautonomia

    :star:The more you know!:star: So, the parasympathetic branch of the autonomic nervous system is responsible for producing a penile erection (or vaginal lubrication) in response to stimulation. This means that if there is a problem with this part of the autonomic nervous system, one might...

    What is the poor man's endothelial function test?

    We all know the poor man's tilt table test, but is there an equivalent for endothelial function? The most usual way to measure endothelial function is via the Flow Mediated Dilation (FMD) test. It is not a high-tech test, but it tends not to be easily available either (not sure why). I am...

    The Latest Long Hauler Research From Dr. Bruce Patterson

    Since they finally seem to have their first paper published soon, this time for real, hopefully, I'd like to discuss this latest update. Their main point for the symptomology is angiogenesis and vasodilation. This also happens in MCAS and CFS/ME, though. This is why histamine-induced symptoms...

    Endothelial Dysfunction in ME

    I thought I'd start a thread to summarize discussions about the different types of endothelial dysfunction that might be found in ME. Please feel free to add to this thread as needed. What is "Endothelial Dysfunction"? Blood vessels are enclosed by a layer of cells called endothelial cells...
