    Abstract:
    BACKGROUND/AIMS: The present study was designed to investigate the short-term safety and efficacy of topical application with body lotion enriched with minerals from the Dead Sea versus 2 different placebo treatments in reducing symptoms of uremic pruritus. METHODS: In this single-center, randomized, double placebo-controlled clinical trial, 78 hemodialysis patients with self-reported uremic pruritus were randomized to twice-daily topical treatment with body lotion enriched with minerals from the Dead Sea (DS) or to each of 2 types of placebo: (1) lotion with no Dead Sea minerals but otherwise identical to DS (P1) or (2) lotion with no active ingredients (P2). Symptoms of uremic pruritus (itching, dryness, peeling, tightness) were evaluated at baseline and 2 weeks (14 days) after treatment intervention using a 5-point Likert scale. RESULTS: Following treatment, significant differences in symptom severity scores between DS and P1 and, separately, between group DS and P2, were not detected. Additionally, when DS was compared to the combined placebo groups (P1 and P2 together), significant post-treatment differences in symptom severity scores were not observed. Symptoms were less severe post-treatment regardless of treatment assignment. CONCLUSIONS: DS was not superior to either of the placebo treatments in the symptomatic relief of uremic pruritus.
