Summary

Pruritus attributable to kidney dysfunction, or uremic pruritus (UP), is a common and distressing symptom that affects patients with chronic kidney disease (CKD). This chapter reviews the available evidence surrounding the symptom of pruritus as it affects patients with CKD. It also outlines the epidemiologic data reported worldwide, describes pathogenesis of UP, and outlines its clinical presentation, diagnosis, assessment tools, and available treatment options. UP has been less extensively studied than pruritus in general and may be caused by mechanisms different than those underpinning pruritus from other etiologies. Pruritus is a symptom and is thus inherently subjective. Scratch lesions can be quantitated; however, this assessment method often fails to capture the significance of pruritus to patients. Acupuncture is commonly used worldwide as a primary, adjunct, or alternative treatment for pain and other symptoms.
