Guest guest Posted March 15, 2006 Report Share Posted March 15, 2006 Why don't they just ask? - -------------------------------------------------------------- Is there any relation between moldy building exposure and chronic fatigue syndrome? Journal: Med Hypotheses. 2006 Mar 7; [Epub ahead of print] Authors: Shahriar Gharibzadeh and Sayed Shahabuddin Hoseini Affiliations: Neuromuscular Systems Laboratory, Faculty of Biomedical Engineering, Amirkabir University of Technology, Somayyeh, Hafez, Tehran 15875-4413, Iran, and Faculty of Medicine, Tehran University of Medical Sciences, Enghelab Street, Tehran, Iran Tel.: +9821 6454 2369; fax: +9821 6649 5655. E-Mail: shahab337@... Available online 9 March 2006. It is reported that workers who are employed in moldy buildings, show different symptoms like respiratory difficulties, fatigue, fever and headache. Hirvonen et al. have reported elevated cytokines (interleukin-1, interleukin-6 and tumor necrosis factor a) and nitric oxide (NO) levels in nasal lavage of workers in exposure to moldy buildings. Due to laboratory tests, Aspergillus fumigatus, Trichoderma, Actinomycetes, etc. were detected in indoor air [1]. On the other hand, chronic fatigue syndrome (CFS) is the current name for a disorder characterized by debilitating fatigue and several associated complaints including headache, sleep disorder, low grade fever and concentration difficulties [2]. It is mentioned that post- infectious, immunological, and psychological factors are involved in the syndrome [3]. Researches in patients with CFS have shown a significant elevation in serum levels of interleukin-1 and tumor necrosis factors a and ß [4]. which can result in the appearance of CFS symptoms. Small amounts of circulating cytokines can enter the cerebrospinal fluid and the parenchyma of the brain [5]. Cytokines administered systemically or directly into the central nervous system have shown to alter the activity of hypothalamus, hippocampus, and prefrontal cortex [6]. In addition, elevated nitric oxide levels have been documented in CFS patients. It is hypothesized that NO plays a significant role in pain sensitization, which is seen in these patients [7]. Moreover, excessive NO production is an important factor in pulmonary manifestations including vasodilation, edema and cytotoxicity [1]. It seems from the abovementioned points that, in accordance with the post-infectious theory of CFS, the exposure to moldy conditions may be a trigger for the onset of CFS. Moreover, the working of persons with CFS in moldy conditions may aggravate their symptoms including pulmonary pain and psychoneurological manifestations. Surely, our hypothesis needs to be validated by experimental evaluation. References [1] M.R. Hirvonen, M. Ruotsalainen, M. Roponen, A. Hyvarinen, T. Husman and V.M.

If you are trying to solve a jigsaw puzzle, what good would it do to throw away those troublesome pieces that just don't seem to go anywhere, when you know that since they were in the box, that they must be part of the puzzle? The best you could do is consider the puzzle finished when you run out of the parts that weren't thrown out, although it looks kind of odd with the pieces missing. - Quote Link to comment Share on other sites More sharing options...
