The effect of ultraviolet A phototherapy on uraemic pruritus was investigated in a placebo-controlled trial. Equivalent and significant reduction of itch was noted in both placebo and treatment groups as assessed by analogue scales and interviews. This reduction in itch could have been the result of either a placebo response or a biological effect of blue light.
