The efficacy of alpha-lipoic acid and/or gabapentin on the oxidant-antioxidant system in patients with diabetic polyneuropathy. International Journal of Research in Medical Sciences. 2020 Aug; 8(8): 2777-27812320-60712320-6012http://imsear.searo.who.int/handle/123456789/212505Background: Diabetic peripheral sensorimotor polyneuropathy is the most common complication seen in patients with diabetes mellitus (DM). Oxidant system plays a crucial role in its physiopathology. We investigated the changes in the serum levels of total antioxidant status (TAS), total oxidant status (TOS), paraoxonase-1 (PON1) and oxidative stress index (OSI) to evaluate the antioxidant efficacy of alpha lipoic acid (ALA) and/or gabapentin in patients with diabetic polyneuropathy (DPN).Methods: Sixty-three type 2 DM patients with diabetic polyneuropathy (DPN) were enrolled in the study. Patients with DPN were divided into four groups in terms of their treatment: Group 1 consisted of treatment-naive patients; patients treated with ALA, gabapentin or combination of ALA and gabapentin comprised groups 2, 3, and 4, respectively. The patients received the medications for at least six weeks.  Serum levels of TAS, TOS, PON1 and OSI were analyzed.Results: No significant difference was observed between the groups according to the oxidative stress parameters studied.Conclusions: The use of ALA and/or gabapentin in patients with DPN did not significantly affect the oxidative stress parameters, including TAS, TOS, PON1, and OSI.Alpha-lipoic acidDiabetic polyneuropathyGabapentinParaoxonase-1Total antioxidant statusTotal oxidant statusJournal ArticleIndiaDepartment of Neurology, University of Health Sciences, Fatih Sultan Mehmet Training and Research Hospital, Istanbul, TurkeyDepartment of Clinical Biochemistry, Ankara Şehir Hastanesi, TurkeyDepartment of Clinical Biochemistry, Ankara Yıldırım Beyazıt University, TurkeyDepartment of Neurology, Ankara Yıldırım Beyazıt University, Turkey
