The Efficacy of Hemp-containing Cream Versus Placebo in the Treatment of Uremic Pruritus

Uremic Pruritus Clinical Trial

Official title: This Study Aims to Compare the Efficacy of Hemp-containing Cream and a Placebo in the Treatment of Uremic Pruritus in Hemodialysis Patients. Patients Were Randomly Assigned Either the Hemp-containing Cream or a Placebo and Evaluated the WI-NRS and Skindex-10 Scores at Week 2, 4.

Status Completed

Clinical Trial Summary

Uremic pruritus is a significant burden on hemodialysis patients, affecting approximately 46% of individuals undergoing dialysis. Various mechanisms, including inadequate dialysis, increased uremic toxins, inflammatory cytokines, parathyroid hormone, phosphorus, dry skin, mast cell histamine secretion, and nerve stimulation through μ-opioid receptors and nociceptors, contribute to uremic pruritus. Current treatments include antihistamines, gabapentin, moisturizer creams, and capsaicin creams, with limited success, as only 10% of patients find relief. Cannabinoids were also mentioned in uremic pruritus treatment but are less commonly used and there are no randomised controlled trial. Cannabinoid binding to CB1 and CB2 receptors inhibits mast cell differentiation, aggregation, and histamine release, whereas cannabinoid binding to TRP-iron receptors reduces peripheral nerve activation. Thus, cannabinoid seem to effective in relieving pruritus via various mechanisms.

This study aims to assess the effectiveness of a hemp-containing cream in comparison to a placebo for treating uremic pruritus among hemodialysis patients.

Clinical Trial Description

Eligible participants is randomly assigned in a 1:1 ratio to receive either a hemp-containing cream or a placebo. then, they are assessed for the severity of itching symptoms using the WI-NRS and their itch-related quality of life using the Skindex-10 score at baseline, week 2, and week 4 of the study. Additionally, adverse effects are documented. Data is collected by the research assistant and recorded in computer with locking password and also was validated with second assistant.

For statistical analysis, continuous variables are compared using an unpaired t-test or Mann-Whitney U test, as appropriate. Categorical variables are compared using a Chi-square test or Fisher's exact test. The adjusted mean difference is used Analysis of Covariance (ANCOVA) , adjusted by score at baseline.

All statistical analyses were performed using Stata v.17.0 (StataCorp, Texas). ;
