The list of agents that have been proposed at one time or another is long buy cheap dapoxetine 90mg on-line bisoprolol causes erectile dysfunction, including human herpes virus type 6 order dapoxetine 60 mg free shipping doctor for erectile dysfunction in mumbai, measles virus order dapoxetine 90mg fast delivery erectile dysfunction doctor in kuwait, rabies virus generic dapoxetine 30mg with amex erectile dysfunction drugs cost comparison, paramyxovirus, corona virus, varicella zoster virus, rubella virus, mumps virus, and retro viruses (Murray, 2002. Even bacteria have been proposed, including Chlamydia pneumoniae and Borrelia burgdorferi. It asserted that a downshift in early life infection may con tribute to the increase in hayfever over time. The initial inter pretation of the hygiene hypothesis was a lack of shift from a perinatal Th2 immune profile to a Th1 immune profile, due to inade quate exposure to antigenic stimulation in a hygienic environment (missing immune deviation) (Romagnani, 2004. If the protective effect of infection depended on the type of exposure and this varied across populations, a differing role for infection could explain the differential validity of the hygiene hypothesis across diseases and countries (Bach, 2005. In summary, it is highly likely that infection plays a role in many autoimmune disorders, although the agent and mechanism may differ from one to another. Chemical agents may play an important role in interacting with infections — an area that has hardly been studied. Whether or not this is so, infection must be controlled in any epidemiological study, since it is a potential confounding factor in any association between chemical agents and autoimmune dis eases. There is a general concern regarding the relationship between autoimmune diseases and vaccination, but large-scale studies have been performed on only two diseases — multiple sclerosis and diabetes mellitus type 1. Subsequently, case–control studies and cohort studies, particularly utilizing computerized prescription databases, failed to demonstrate any association. However, a recent major Danish record linkage study conclusively showed no relationship between the two (Hviid et al. Arthritis has been described following administration of hepa titis B, rubella, mumps and measles, influenza, diphtheria–pertussis– tetanus, and typhoid vaccine. However, it does appear that rubella vaccination may, in genetically susceptible individuals, lead rarely to an arthropathy. Guillain-Barré syndrome was particularly associated with swine flu vaccine in 1976. Since it is a constituent part of thimerosal, which is used as a preservative in killed vaccines, concern has been raised with regard to its role in immune-mediated diseases and autism (Clarkson, 2002. This compound has caused illness and several deaths due to erroneous handling when used as a disinfectant or as a preservative in medical prepar ations. The authors also reported that the discontinuation of thimerosal-containing vaccines in Denmark in 1992 was followed by an increase in the incidence of autism. In contrast, epidemio logical evidence, based upon tens of millions of doses of vaccine administered in the United States, that associates increasing thimerosal from vaccines with neurodevelopmental disorders was reported by Geier & Geier (2003. An analysis of the Vaccine Adverse Events Reporting System database showed statistical increases in the incidence rate of autism, mental retardation, and speech disorders with the use of thimerosal-containing diphtheria, tetanus, and acellular pertussis vaccines in comparison with thimerosal-free vaccines. It is a poor inducer of cell-mediated immunity, and there is no epidemiological evidence of it leading to autoimmunity. Recently, some concern has been raised in France in patients where aluminium hydroxide induced persistent macrophagic myofasciitis is present. It has been hypothesized that the persistence of this lesion may be associated with a higher incidence of a syndrome with arthralgias, myalgias, and chronic fatigue (Gherardi et al. Coeliac disease is an example of an autoimmune disease with a clear dietary link — the immunological response to specific proteins in wheat, barley, and rye producing autoantibodies directed against tissue transglutaminase and mucosal damage in the small intestine. The role of iodine in autoimmune thyroid diseases is discussed in chapter 8 (section 8. The following summary of dietary factors focuses on experimental studies using animal models and human studies of the etiology and progression of multiple sclerosis, diabetes mellitus type 1, inflammatory bowel diseases, rheumatoid arthritis, and lupus. The basis for much of this research is the general immunomodulating effect of dietary components, particularly with respect to cytokine production and inflammation. In general, data from studies in humans are more limited and less consistent than the data from animal studies. Fasting can improve symp toms in some patients with rheumatoid arthritis (possibly through an anti-inflammatory effect of fasting mediated through leptin), but the effects are not sustained when the fasting period is over (Muller et al. In mouse models of multiple sclerosis (experimental autoimmune encephalomyelitis) and diabetes mellitus type 1, leptin secretion was closely linked to disease onset (Matarese et al. Recent studies report an effect of leptin on T cell stimulation and production of proinflammatory cytokines (Sanchez-Margalet et al. Caloric restriction in lupus mouse models inhibits the disease process and prolongs survival (Leiba et al. The fatty acid composition of foods is determined by the length of the carbon chain and the number and location of double bonds. The n 3 or omega-3 fatty acids are those with one or more double bonds, the first of which is located at the third carbon from the omega end of the carbon chain. The essential fatty acids are those that cannot be synthesized and so are available only from foods or supplements. The relative balance of different prostaglandins and leukotrienes affects the inflammatory response. Because of the potential effects on inflammation and immune mediated function, there has been considerable interest in the potential therapeutic role of omega-3 fatty acids in autoimmune disease. The randomized clinical trials tend to be relatively small, but there is some evidence of improvement in terms of reduced joint count and morning stiffness in trials of fish oil supplementation (Fortin et al. There have also been some small trials (n < 30) of omega-3 supplementation in patients with systemic lupus erythematosus, but these studies were conducted before the adoption of standardized measures of disease activity and damage. In general, some improvements in lipid profiles and inflammatory measures have been seen, but there are mixed results with respect to improvements in clinical status (Leiba et al. In a large observational (non-randomized) study in Japan, there was no association between intake of total fat, type of fat, or omega-3 fatty acids and subsequent disease activity among 216 lupus patients (Minami et al.
