  • Title: beta(2)-Microglobulin-selective direct hemoperfusion column for the treatment of dialysis-related amyloidosis.
    Author: Kutsuki H.
    Journal: Biochim Biophys Acta; 2005 Nov 10; 1753(1):141-5. PubMed ID: 16168723.
    Abstract:
    Lixelle is a direct hemoperfusion-type adsorption column that was developed to selectively eliminate beta2-microglobulin (beta2-m) from the circulating blood of patients with dialysis-related amyloidosis (DRA). The adsorbent in Lixelle comprises porous cellulose beads to which hydrophobic hexadecyl alkyl chain is covalently bound. One milliliter of wet Lixelle beads eliminates more than 1 mg of beta2-m in vitro. In hemodialysis patients who were treated with Lixelle, Lixelle improved joint pain, nocturnal awakening, pinch strength, motor terminal latency, and their activity of daily living. The adsorbent adsorbs beta2-m selectively but not specifically, as well as inflammatory cytokines such as interleukin-1beta and IL-6 which are considered to be involved in the development of DRA. Lixelle treatments reduce the circulating levels of beta2-m and inflammatory cytokines, thereby improving the symptoms of patients with DRA.
