Hi, all.
Here is some history concerning low sed rate and CFS: David Berg, who used to be the owner of the Hemex lab in Arizona, and later sold the lab and is operating now as a consultant, developed the concept of ISAC (Immune System Activation of Coagulation) several years ago, and published at least one paper on this in connection with CFS.
The idea is that the immune system normally promotes some deposition of fibrin in the capillaries when an infection is present, in order to confine the pathogens. This is a normal action.
However, some people have inherited one or more mutations in the proteins that are involved in the coagulation cascade, so that their immune systems promote too much fibrin deposition. This ends up obstructing the diffusion of oxygen from the capillaries into the cells.
David noted a correlation between low SED rate and the presence of ISAC. If the SED rate is below about 4 or 5 mm per hour, ISAC is likely. The tests involved in checking for ISAC were fairly expensive, and some doctors just checked for SFM (soluble fibrin monomer) first. If this was elevated, then they might test further.
The treatment for this was low-dose heparin, and later people started using nattokinase, serrapeptase or lumbrokinase. It was found that it was important to treat to limit the pathogens when using these anticoagulants, or otherwise the pathogens would propagate and the ISAC would become worse. So people used transfer factors together with the anticoagulants, and that seemed to help quite a few people.
It's true that most conventional doctors don't recognize a low SED rate as being indicative of anything abnormal. They have been trained to look only for high values, as an indication of inflammation or infection.
Not all PWCs have a low sed rate, as has been noted. According to David Berg, it depends on whether the person has also inherited mutations in one or more of the proteins in the coagulation cascade.
Best regards,
