Current views on the use of interferons in the treatment of polycythaemia vera (RCD code: VIII)
Interferon alpha is a molecule associated with stimulation of immune system cells, resulting in an anti‐proliferative and immunomodulatory effect. It has been demonstrated that interferon reduces the number of platelets, leukocytes, and erythrocytes in patients suffering from chronic myeloproliferative diseases. In this paper, we present an overview of selected research evaluating the efficacy and adverse effects of various recombinant interferons used in the treatment of polycythaemia vera. We have analysed previously reported studies on the use of interferon. Interferon alfa‐2a was the first interferon approved for standard treatment of polycythaemia vera, while the next was pegylated interferon alfa‐2a. We also present recent results from studies on a newly modified molecule, ropeginterferon, a mono‐pegylated form of interferon alfa‐2b. Interferons reduce the number of phlebotomies required in patients with polycythaemia vera, accompanied by a resolution of typical disease symptoms. Treatment is well tolerated by the majority of patients. JRCD 2019; 4 (2): 34-36.
