Ischemia modified albumin levels and increased oxidative stress in patients with multiple myeloma

Abstract

Background: Impaired oxidative/antioxidative balance plays an important role in the pathogenesis of many diseases, including cancer. The aim of this study was to evaluate the levels of the novel marker ischemia modified albumin (IMA) and albumin adjusted-IMA (Adj-IMA) in patients with multiple myeloma (MM) as well as its association with total antioxidant status (TAS), total oxidant status (TOS) and oxidative stress index (OSI). Methods: Forty patients with MM (18 females, 22 males; mean age 67.55±8.39 years) and forty age/sex-matched healthy persons (19 females, 21 males; mean age 66.37±6.76 years) were included in this study. Serum levels of IMA, TAS, TOS were analyzed and Adj-IMA and OSI was calculated. Results: Serum IMA, TOS and OSI levels were significantly higher in patients with MM compared to controls (p<0.001 all parameters). There was no significant difference for serum albumin-adjusted IMA and TAS levels between groups (p=0.83 and p=0.17 respectively). Conclusions: In this study, an impaired oxidative/antioxidant status in favor of oxidative stress was found in MM patients. This observation was not confirmed by Adj-IMA calculation. Further studies are needed to establish the relationship of IMA and oxidative stress parameters in multiple myeloma and their relationship to MM and other cancers.
