Abstract
Multiple myeloma is a malignant silent incurable plasma cell disorder. The present study aimed to assessed the activation of the oxidative stress pathway in affected patients. Advanced oxidation protein products (AOPPs), malondialdehyde (MDA), adenosine deaminase (ADA), total antioxidant capacity (TAC) levels, glutathione, ascorbic acid (vitamin C), α-tocopherol (vitamin E) in addition to related enzymes glutathione peroxidase (GSH-Px), glutathione reductase (GSH-R) and superoxide dismutase (SOD) were analyzed in sixty patients with multiple myeloma before and after one month treatment with induction therapy. The results of the study showed a significant elevation in AOPPs, MDA, ADA levels in patients with multiple myeloma before and after treatment in comparison to healthy control samples In contrast TAC glutathione, vitamin C and E, and the antioxidant enzymes levels were decreased significantly. On comparing samples of MM patients after treatment, there was significant increase of TAC glutathione, vitamin C and E, and the antioxidant enzymes in parallel with decreasing AOPPs, MDA and ADA levels in comparison with samples of patients before treatment. The results indicate oxidative stress and DNA damage activity increase in MM and are alleviated in response to therapy.
Highlights
Multiple myeloma (MM), recognized as plasma cell myeloma or Kahler’s disease a type of white blood cell normally responsible for producing antibodies (Raab et al, 2009), Multiple myeloma is a malignant still incurable plasma cell disorder (Campanella et al, 2012), it is a B-cell malignancy characterized by the accumulation of clonal population of plasma cells (Xuan-li et al, 2013)
