Abstract
Acute phase proteins are useful inflammatory markers in horses. Haptoglobin (Hp) serum level is increased in horses undergoing different inflammatory processes, including arthritis. However, Hp concentration has not been assessed in inflammatory synovial fluid (SF). The aim of the present study was to investigate the Hp response in serum and SF in horses undergoing experimentally induced arthritis. For this purpose, serum and SF samples were collected from 12 animals before amphotericin B-induced arthritis was created (T0, healthy) and 15Â days after the lesion induction (T1, joint inflammation) and Hp was determined by single radial immunodiffusion. The Hp increase between T0 and T1 was significant in both serum and SF, and serum Hp concentration at T0 was significantly higher than in SF, but significant differences were not found at T1, indicating a higher Hp increase in SF. A significant positive correlation for Hp concentration between serum and SF samples was found. These results highlight the potential usefulness of Hp as inflammatory marker in horses, showing for the first time the increase of Hp in SF from joint inflammation in the horse.
