Study summary

The purpose of this study is to determine whether Fumaria Parviflora L. can minimize severity of pruritus in patients with end-stage renal disease.

Read the detailed description

Uremic Pruritus is still a common complication in end-stage renal disease patients. The pathogenesis of Uremic Pruritus is unknown, therefore treatments are ineffective. According to several studies Uremic Pruritus is not an isolated skin disease. It seems to be a systemic inflammatory disease with a deranged balance of T helper cell differentiation. In this study investigators considered to evaluate effect of Fumaria Parviflora L. in uremic pruritus by a double blind placebo control clinical trial. It is hypothesized that oral Fumaria Parviflora L. may minimize uremic pruritus by decreasing serum Interferon gamma (IFN-γ) and high-sensitive C reactive protein (hs-CRP).

What researchers measure

Primary outcomes

  1. Severity of Pruritis as measured by a visual analogue scale (VAS)

    A '0' score represented absence of pruritus and a '10' represented the greatest severity of symptoms.

    Time frame: 3 months

Secondary outcomes

  1. Serum Interferon-gamma level

    Time frame: 4 months

  2. Serum IL-4 level

    Time frame: 4 months

  3. Serum high-sensitive C reactive protein (hs-CRP)

    Time frame: 4 months
