The study was performed to test the hypothesis that oxidative stress is increased and neutrophil function is decreased in cats with diabetes mellitus (DM). Oxidative stress is considered a key component in the pathophysiology of type 2 diabetes mellitus in people. It is estimated that 85% of cats with DM are type 2 diabetics. The study included 20 control and 15 diabetic cats with measurements for oxidative stress and neutrophil function. The cats were fed a diet designed for feline diabetics (Purina DM Dietetic Management Feline Formula) for 8 weeks, and then assays were repeated. Plasma superoxide dismutase (SOD) was significantly less in cats with DM than the control cats, consistent with a greater degree of oxidative stress in the DM group. Glutathione peroxidase, an antioxidant enzyme, was increased significantly in both groups following 8 weeks of consuming a diabetes-specific diet. Other parameters of oxidative stress studied, plus neutrophil function, were similar between groups and did not change following dietary intervention. The DM cats were significantly older and heavier than the control cats and these factors could have affected differences between the two groups. The findings support continued study of antioxidant supplementation and dietary intervention in diabetic cats. [VT]
