David Wheldon Comments on endotoxins & reactions
Cpn endotoxin is about 100 times less powerful than Neisserial endotoxin, but there must be a lot of it released, particularly with the active killing by metronidazole. Hence the need for caution at this stage of treatment. The long-term damaging effect of far more potent endotoxins on the CNS is vividly illustrated by this story: http://www.endotoxin.gmxhome.de/ which resulted in a letter in the BMJ: http://oem.bmjjournals.com/cgi/content/full/60/5/378
One quite common side effect of Cpn treatment is vestibular disturbance. A number of other medics who treat CFS with antibiotics have noticed this. It can go on for months, tends to have a diurnal rhythm and can be quite incapacitating. Its severity seems to be linked to bacterial load. The diurnal pattern suggests that it may be of host origin, perhaps cytokine. Here's a link to a webpage which notes the association between vestibular disturbance and cognitive deficits. http://www.backgroundfacts.com/menieres/COGDIS.htm
