Equine eczema is a hypersensitive, allergic skin condition that recurrently manifests in horses, especially in the summer season due to insect bites. This study aims to evaluate the hematological alterations, oxidant/antioxidant changes, and protein and lipid profiles in horses suffering from equine eczema. Thirty (30) horses were included in this study (20 males, 10 females), classified into the healthy control group (n = 10) and the equine eczema group (n = 20). All horses were subjected to a complete physical examination. Blood samples were collected for hematological profile and estimation of serum concentration of total antioxidant capacity (TAC), malondialdehyde (MDA), C-reactive protein (CRP), serum zinc, copper concentrations, total protein, albumin, globulin values, triglycerides, and cholesterol concentrations. The most consistent hematological alteration was elevated eosinophils in eczema-affected horses. The oxidant-antioxidant status showed a significant increase in malondialdehyde with a significant decrease in total antioxidant capacity, serum zinc, and copper concentrations. No significant changes were detected in both protein and lipid profiles. In conclusion, equine eczema is a stressful allergic skin disease that alters hematological and oxidant/antioxidant status in the equine and disrupts the horse’s quality of life. Further studies regarding the addition of antioxidant compounds to the therapeutic regimen are needed.
