Abstract

Juvenile polyarteritis syndrome (JPS) is an idiopathic febrile disease in dogs. Elevated serum levels of interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) have been reported in human patients with vasculitis. We investigated whether these cytokines are also elevated in serum of dogs with JPS using sensitive bio-assays. Increased levels of IL-6 activity were detected in the serum of 12 acutely ill dogs, whereas the IL-6 activity decreased to low or undetectable levels during convalescence. Treatment of 5 acute JPS dogs with prednisone resulted in a rapid clinical improvement accompanied by a decrease of IL-6 activity. Withdrawal of prednisone treatment caused reappearance of clinical symptoms and high serum IL-6 activity within a few days. TNF activity could not be detected in the samples of normal dogs, convalescent JPS, or acute JPS dogs. These studies support a role for IL-6 in the pathogenesis of JPS.
