Study Shows that Red Blood Cells are Stiffer in People with ME

Researchers have published a paper that shows various measures of deformability in the red blood cells of people with Myalgic Encephalomyelitis / Chronic Fatigue Syndrome (ME/CFS) indicating that they are significantly stiffer in people with ME/CFS than those from healthy controls.

The observations suggest that red blood cell transport through microcapillaries may explain, at least in part, the ME/CFS phenotype, and promises to be a novel, first-pass diagnostic test.

Ronald W. Davis, PhD, who collaborated on the paper, writes:

“It potentially could be a biomarker, and we are proceeding to design new devices that will make a clear distinction between patients and healthy controls. These devices will be hand-held and easy to use by doctors in their offices, or in clinical testing labs.

Past work has looked primarily at the shape of red blood cells, which is difficult to quantitate. Our approach will give a clear quantitative number. It measures the ability of red blood cells to deform while squeezing into a capillary, something that blood cells must do for healthy flow. We measure hundreds of cells from each patient, so, because of this, even though the number of patients is low, we get a very statistically significant distinction between patient and healthy cells’ deformability.

We are putting our energy into developing the new devices as soon as possible.”

The Red Blood Cell Deformability research paper has been published as open source in Clinical Hemorheology and Microcirculation. The authors are Mohsen Nemat-Gorgani, PhD, of Stanford University, and Anand Ramasubramanian, PhD, of San Jose State University, in collaboration with Ron Davis, PhD, and their teams. 

The study has been fully funded by the Open Medicine Foundation through the support of their generous donors.

  1. Maybe this is why 2 different GPS accused me of being an alcoholic (after blood tests) when in fact I was at that time completely teetotal and had been for many years …. I think if you are an alcoholic it also affects the shape or size of your red blood cells ? They would not believe I was teetotal !

    This change in red blood cells has been known for years – Dr Les Simpson New Zealand. The reason for this has yet to be discovered.

Infection-associated chronic disease experts needed at ARPA-H

Congress launched ARPA-H (the Advanced Research Projects Agency for Health) this past March to focus on high-risk, high-reward research projects with the goal to solve intractable health problems. As ARPA-H is in the process of hiring its first cohort of program managers, #MEAction and a coalition of chronic disease advocacy groups have published an open
