Chronic fatigue syndrome and/or fibromyalgia as a variation of antiphospholipid antibody syndrome: an explanatory model and approach to laboratory diagnosis
Abstract
Chronic Fatigue and/or Fibromyalgia have long been diseases without definition. An explanatory model of coagulation activation has been demonstrated through use of the ISAC panel of five tests, including, Fibrinogen, Prothrombin Fragment 1+2, Thrombin/ AntiThrombin Complexes, Soluble Fibrin Monomer, and Platelet Activation by flow cytometry. These tests show low level coagulation activation from immunoglobulins (Igs) as demonstrated by Anti-B2GPI antibodies, which allows classification of these diseases as a type of antiphospholipid antibody syndrome. The ISAC panel allows testing for diagnosis as well as monitoring for anticoagulation protocols in these patients.

Conclusions:
CFS and/or FM patients who have a hereditary deficiency for thrombophilia or hypofibrinolysis may be unable to control thrombin generation properly. We have found that three out of four CFS and/or FM patients have a genetic deficiency (unpublisheddata). Certain pathogens induce the immune system generation of APL antibodie s and can be a triggering mechanism
for APS. Once antibodies are formed, protective proteins are dislodged from endothelial cells, exposing PS. Coagulation proteins bind on exposed PS surfaces, generating thrombin on the EC surface.
Excess thrombin converts fibrinogen to SFM, which may be deposited on the EC surface and/or circulate in the plasma. Fibrin deposition leads to decreased oxygen, nutrient and cellular passage to tissues around the microcirculation. This hypercoagulable state may cause localized pathology in many tissues, yielding the systemic compromises and symptoms characteristic of the CFS-FM complex.
Since this hypercoagulable state does
not necessarily result in a thrombosis, but rather in fibrin deposition, we suggest that an alternative name for this Antiphospholipidantibody process would be immune system activation of coagulation (ISAC) instead of antibody-mediated thrombosis [18]. Once
this hypercoagulable state is detected, appropriate anticoagulant therapies may be given to relieve patient symptoms. These studies will be presented in a separate report.
