Abstract

Objective—To determine plasma malondialdehyde (MDA) and serum vitamin E concentrations in dogs with immune-mediated hemolytic anemia (IMHA) and healthy control dogs.

Sample Population—Serum and plasma samples from 36 dogs with IMHA and 40 healthy control dogs.

Procedure—Blood samples were collected from all study dogs. Plasma MDA concentrations were measured by use of a commercial colorimetric assay, and serum vitamin E concentrations (α-, γ-, and δ-tocopherol concentrations) were measured via high-performance liquid chromatography.

Results—Plasma MDA concentrations were significantly higher in the dogs with IMHA than in the control dogs. Compared with control dogs, serum α-, γ-, and δ-tocopherol concentrations were significantly lower in the IMHA-affected dogs.

Conclusions and Clinical Relevance—Results indicated a state of oxidative stress and reduced antioxidant reserve in dogs with IMHA; this finding provides support for further investigation of the potential benefits of antioxidant treatment in dogs with this disease. (Am J Vet Res 2004;65:1621–1624)
