Effects of acupuncture on chronic idiopathic pruritus: an uncontrolled pilot study evaluating inflammatory changes...

Background Conduct a pilot study addressing the efficacy of acupuncture in the treatment of chronic idiopathic pruritus to aid in the design of a larger clinical trial. Routine laboratory tests to assess systemic inflammation in addition to subjective patient surveys were performed provide documentation of efficacy of treatment. Methods Patients with chronic pruritus who did not respond to standard treatment were recruited to participate. After exclusion of systemic or known reversible causes, each patient received up to 10 treatments which were performed approximately one week apart. Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) were measured before and after a series of acupuncture treatments to evaluate levels of inflammation and pre- and post-treatment surveys were conducted to evaluate levels of perceived itch. Results Only one of the ten patients in this study possessed an elevation of ESR before treatment. This patient's ESR value returned to normal range after treatment and this participant reported subjective relief of her pruritus. Conclusions Future studies on the efficacy of acupuncture in the treatment of chronic idiopathic pruritus should focus on those patients with measurable levels of inflammation at the initiation of the study or utilize alternative and more comprehensive values to monitor disease response.
