Abstract BACKGROUND AND AIM: Oxidative stress is associated with insulin resistance pathogenesis, insulin secretion deficiency, and complication onset. Fermented papaya preparation (FPP), a dietary supplement obtained by fermentation of the papaya fruit, may be used as an antioxidant in the prevention of diabetic complications. METHODS AND RESULTS: Platelets from 30 patients with type 2 diabetes mellitus (DM 2) and 15 healthy subjects were analyzed to evaluate the in vitro effects of FPP incubation. Na+/K+-adenosine triphosphatase (ATPase) activity, membrane fluidity, total antioxidant capacity (TAC), superoxide dismutase (SOD) activity, and conjugated diene levels were determined. In vitro FPP incubation improved platelet function, by enhancing Na+/K+-ATPase activity and membrane fluidity, and ameliorated the antioxidant system functionality, through an increase in TAC and SOD activity and a parallel decrease in conjugated diene levels in patients with DM 2. CONCLUSION: Our data suggest that the incubation with FPP may have a protective effect on platelets from patients with DM 2, by preventing the progression of oxidative damage associated with diabetes and its complications.

Abstract

Abstract BACKGROUND AND AIM: Oxidative stress is associated with insulin resistance pathogenesis, insulin secretion deficiency, and complication onset. Fermented papaya preparation (FPP), a dietary supplement obtained by fermentation of the papaya fruit, may be used as an antioxidant in the prevention of diabetic complications. METHODS AND RESULTS: Platelets from 30 patients with type 2 diabetes mellitus (DM 2) and 15 healthy subjects were analyzed to evaluate the in vitro effects of FPP incubation. Na+/K+-adenosine triphosphatase (ATPase) activity, membrane fluidity, total antioxidant capacity (TAC), superoxide dismutase (SOD) activity, and conjugated diene levels were determined. In vitro FPP incubation improved platelet function, by enhancing Na+/K+-ATPase activity and membrane fluidity, and ameliorated the antioxidant system functionality, through an increase in TAC and SOD activity and a parallel decrease in conjugated diene levels in patients with DM 2. CONCLUSION: Our data suggest that the incubation with FPP may have a protective effect on platelets from patients with DM 2, by preventing the progression of oxidative damage associated with diabetes and its complications.
