Dr. Enlander statement on recent controversy over the PACE trial:
We have followed with great interest the events of the past 2 weeks involving the PACE studies which have been published over the years in the Lancet, Lancet Psychiatry, Psychological Medicine, and others. The publication of New York Times journalist David Tuller’s through investigation on Virology Blog, the release this past week of a PACE followup paper, the resultant media coverage, and the interest of Psychology Professor and blogger James C. Coyne has all added up to probably the most eventful week for ME and CFS patients, physicians, and researchers, for some time.
In clinical practice, it is hard to say we have ever found the conclusions of PACE to be particularly helpful. We view ME as primarily a condition of immunological dysfunction with often-severe neurological symptoms, and have had best success treating it in accordance with that viewpoint. Without ever desiring to quarrel with the PACE investigators, their approach has encouraged exertion in a condition that we see to produce post-exertional relapse. In fairness, they have always maintained that their approach of Cognitive Behavioral Therapy, often combined with Graded Exercise Therapy, is not an indication that they view ME or CFS as a primarily psychological condition. However, it is not hard to see why others may draw that exact conclusion regarding their views. As such, for many, PACE provides a de facto overview of the condition itself, whether intended or not. And it can be difficult to extrapolate the conclusions of PACE into a view that ME and CFS should be viewed as primarily physical condition (s). This is, in my opinion, to the detriment of all involved, regardless of any relevance to discussion of Cartesian Dualism.
The issue of design issues and methodological flaws, questionable entry criteria and investigator bias, in PACE is another matter. The Lancet saw fit to publish the initial paper; individuals such as Malcolm Hooper and Tom Kindlon, among others, have spent years analyzing it, and its followups; and it is helpful to remember that this was a publicly-financed study. And an expensive one, at that, in a realm where funding for ME and CFS research (with, perhaps, the exception of research that might suggest primary psychological and/or psychiatric etiology) is and has always been scant, on a global scale. This, also, has been to the detriment of all involved.
My position has always been consistent: this is a physical disease. Yet I have never denied that there is a secondary depression that mirrors those found in other serious physical diseases. As such, I've never felt it proper to suggest that there should be no role for psychological and/or psychiatric involvement--provided that involvement is proportional. The existing paradigm seems to place psychiatric involvement at the forefront, to the exclusion of all else. We don't have to deny any role to our esteemed colleagues; we can work together. At present, though, their role is clearly overstated, and their theories perhaps less than helpful, especially if they serve to put roadblocks in the way of medical research and investigation into treatments.
So it is hard not to see the vigorous discussion of the past week as a firmly positive, and professional, development. There have been pertinent questions, most of which remain unanswered, for years. Perhaps we shall be provided with some much-needed answers soon.
