Effect of Chiropractic Treatments on the Endocrine and Immune System in Asthmatic Patients
Proceedings of the 2002 International Conference on Spinal Manipulation, Toronto Ontario, Canada, Oct 2002: 57-8
Conclusion: the FCER funded study aims to determine the effects of chiropractic treatment of the endocrine and immune system of asthmatic patients. We have determined from the data thus far that direct chiropractic treatment (6 weeks) reduces salivary cortisol levels over the 14-week period of this trial. We do however note an initial increase associated with the first 2-3 weeks of treatment. This could either be due to anxiety associated with visiting a clinic or due to the physical nature of the chiropractic treatment. That some patients showed a slight increase 2-3 weeks into clinic visit suggest the former. However full analysis of the data at the conclusion of the trial with respect to individual patient changes versus treatment regime received will be required to finalize this question. There is no indication at this stage that the reduction in cortisol after chiropractic treatment is due to the well characterized placebo effect as both group B and Group C cortisol values remained unchanged from the start to the end of the trial.
In support of our hypothesis outlined above we show an increase in salivary IgA levels for group A patients. We expect this to be partly responsible for the decrease in the severity and number of asthmatic attaches experienced by these patients. The most striking feature was the decrease in the erratic nature of IgA levels for group A patients. We attribute this to an increase in basal IgA levels associated with decreased cortisol and hence a better ability of patients to ward off potential pathogenic invasion (or the like) which ultimately shows the increasing /decreasing erratic IgA patterns we observe.
Whether chiropractic treatment effects both the endocrine and immune systems independently or one system through the other requires further analysis of our biochemical data and questionnaire data for individual patients. Full analysis of our data, which we plan at the conclusion of this trial, will also have the benefit of answering a large number of questions related to the efficacy of chiropractic treatment regimes. It is the comprehensive nature of this trial that will make this possible. Our results strongly suggest somatovisceral mechanisms are involved in chiropractic treatment.
