Yes that logic makes sense, and I'm inclined to agree. But then how to explain Chia's claims? I don't think he's actively misleading people to promote a supplement he sells at cost. That doesn't seem to be in his character. I also don't think he's blind to his own patient population's level of improvement.
I agree, I don't think Dr Chia would exaggerate the effectiveness of his treatment. He is a fact-based physician and researcher, and dedicated to uncovering the fine details of ME/CFS (for example, he a stickler for investigating patients' full history leading up to their ME/CFS, and through this thoroughness was able to uncover one new causal factor in ME/CFS, namely the
corticosteroid + virus trigger of ME/CFS).
Incidentally, to give you an example of his interest in researching patient histories, when I speculatively wrote to Dr Chia in 2008, sending him a link to my website which detailed all the mental and physical symptoms the nasty virus I caught had triggered in me, even though I was not even his patient, he was interested enough to read my entire website, and was kind enough to give me some good advice and info about viruses and ME/CFS.
Dr Chia did not have the funding to do a full oxymatrine study, so he performed a quasi-study, the results of which he detailed in the Invest in ME 2010 London Conference, and I have the video. In this study, he treated 100 patients with oxymatrine, and another 114 he used as healthy controls that were not treated (he did though treat them later with oxymatrine). He mentions a 52% improved on oxymatrine in this quasi-study, versus an 6% improvement in healthy controls. But he does not provide any figures on the percentage of patients that had a dramatic improvement on oxymatrine. Details of this quasi-study details are also to be found in
Dr Chia's oxymatrine patent.
But how can we reconcile this 30% of patients that Dr Chia says have dramatic improvements on oxymatrine, with the fact that there are not that many reports online of these dramatic improvements.
Switching into brainstorming mode for a moment, the first crazy idea that springs to mind is that because Dr Chia is based in Southern California, then assuming many of his patients are locals, they are going have higher sunshine exposure, which leads to higher levels of vitamin D, which effects Th1/Th2 in complex ways.
And vitamin D is also important in fighting intracellular pathogens (of which non-cytolytic enteroviruses are one); indeed, the Marshall Protocol for ME/CFS uses Benicar (which powerfully activates the vitamin D receptor, like a super-powered vitamin D) to fight intracellular pathogens. So maybe oxymatrine + vitamin D gets better results. But this is quite a way out suggestion, and in any case, I am not sure just how many of Chia's patients are locals, as people travel a long way to see him.
