Effects of short courses of different doses of prednisone and dexamethasone on serum third component of complement (C3) levels in dogs.
The effect of different doses of prednisone and dexamethasone on serum C3 levels was determined in 35 dogs. Dogs in Group A (n = 15) were administered prednisone (1.1 mg/kg/day) for 14 days; dogs in Group B (n = 10) were given prednisone at 2.2 mg/kg/day for 7 days; dogs in group C (n = 10) were administered dexamethasone (0.25 g/kg/day) for 7 days. Serum C3 concentrations were determined using a sandwich ELISA in samples obtained before and after glucocorticoid administration. Concentrations were expressed as a percentage of a reference standard. No statistically significant differences were found after glucocorticoid administration in all groups. Thus, short-term administration of prednisone and dexamethasone at commonly used doses did not result in significantly lower serum C3 levels.
