Axial spondyloarthritis (axSpA) is a common systemic autoinflammatory disease affecting approximately 7 in 1.000 individuals. Recent investigations suggest that, through certain concentration/meditation techniques, it is possible to modulate autonomic activity. The endotoxemia experiment in an individual (named Wim Hof) who used a self-created concentration/meditation technique is strongly supportive of these findings. The use of his technique - including breathing techniques, training of mindset and concentration, and gradual cold exposure - seemed to evoke a controlled stress response. This response was characterized by sympathetic nervous system activation and subsequent catecholamine/cortisol release, which seemed to attenuate the innate immune response. The remarkable results in the studied individual led to a randomised controlled trial of this technique at the Radboud UMC. Twenty-four healthy individuals were randomised to receive an instruction course of the technique or no instructions at all and subsequently underwent an endotoxemia experiment. The experiment involved the intravenous administration of very low doses of lipopolysaccharide and measuring the in-vivo cytokine response and clinical symptoms. The results of this study have shown a direct biological effect on in-vivo cytokine production and are strongly encouraging the evaluation of the technique's efficacy in clinical practice.
