The Marshall Protocol devised by Professor Trevor Marshall is designed to treat chronic diseases such as sarcoidosis, ME/CFS and several other illnesses. Trevor Marshall proposed that these diseases are all caused by L-form bacteria which create an intracellular infection inside cells.
Trevor Marshall theorized that L-form bacteria are able to synthesis proteins which block the vitamin D receptor (VDR) located inside the cell, and they do this in order to evade the immune response.
The VDR is the on/off switch for certain immune responses inside the cell, so by blocking the VDR with a protein, pathogens which live inside cells can thwart the intracellular immune attack, which allows them to survive long-term inside cells.
To address this thwarting of the immune response, the Marshall Protocol (MP) involves taking a blood pressure drug called Benicar (olmesartan), which computer modeling indicates can knock the bacterial protein off the VDR, and then bind to and activate the VDR, thereby switching on the intracellular immune response, and thus killing the intracellular pathogens.
But although Trevor Marshall proposed that ME/CFS is caused by intracellular L-form bacteria, there is no evidence that this is the case: ME/CFS has been linked to various viruses, and also to the intracellular bacterium Chlamydia pneumoniae, but not to L-form bacteria.
But nevertheless some people report that the Marshall Protocol improved their ME/CFS, including researcher Amy Proal (one of Trevor Marshall's colleagues), who had Epstein-Barr virus ME/CFS which was cured by the Marshall Protocol. So if we assume that ME/CFS is caused by chronic intracellular viral infection, and not by L-form bacteria, how does the Marshall Protocol work for ME/CFS caused by viral infection?
Well interestingly enough, Epstein-Barr virus (EBV) is also able to synthesize a protein which blocks the VDR, again for the purpose of thwarting the immune response. This protein is called EBNA3, and this paper describes how EBV makes EBNA3 in order to block the activation and functioning of the VDR as an immune evasion strategy.
This suggests that the Marshall Protocol might be effective for EBV ME/CFS, but may not work for ME/CFS associated with other viruses (like coxsackievirus B or HHV-6).
Unfortunately on Trevor Marshall's forums, the people trying the MP as a treatment for ME/CFS were not was thinking in terms of viral causes of ME/CFS; they were all following Marshall's ideas about L-form bacteria being the cause of ME/CFS. So nobody on these forums paid much attention to the various viral subtypes of ME/CFS, and whether the MP might work for some viral subtypes but not others.
But the fact that EBV blocks the VDR suggests that the MP may work if you have EBV ME/CFS. This form of ME/CFS usually appears after mononucleosis (glandular fever). Mononucleosis is caused by EBV 90% of the time (but more rarely may instead be caused by cytomegalovirus infection).
So for those with EBV ME/CFS, the Marshall Protocol might be worth revisiting. Of course if you have other co-infections alongside EBV, then the MP may not work very well. MP may only work well for ME/CFS patients who have chronic active EBV infection alone (which may be a fairly small subset of ME/CFS patients).
It would thus be an idea to test for the main 7 pathogens linked to ME/CFS, to see which you have. These 7 are: coxsackievirus B, echovirus, EBV, cytomegalovirus, HHV-6, parvovirus B19 and Chlamydia pneumoniae. The appropriate tests for these are detailed here.
Note: in the past antibiotics were used in the MP alongside Benicar, but these days antibiotics are not considered important, so you do not need to take these. Vitamin D avoidance (including from sunlight) I believe is still considered important in the MP; but note that the overall idea of the MP is not to reduce VDR activation through vitamin D avoidance, but to increase VDR activation by taking Benicar.
Note that EBV is not the only virus which thwarts the functioning of the VDR for immune evasion reasons: cytomegalovirus has also been shown to thwart the VDR for survival purposes. However, in the case of CMV infection, this down-regulates VDR expression, rather than blocks VDR activation. Thus the Marshall Protocol may not work for CMV ME/CFS, because the MP only unblocks the VDR, but I don't think it can counter a down-regulation of VDR expression.
