Abstract:
Signs related to spinal pain are commonly reported in dogs with noninfectious, nonerosive, idiopathic immune-mediated polyarthritis (IMPA). This study examined the prevalence and etiology of spinal pain in these dogs through a retrospective review of 62 case records of dogs with IMPA. All dogs with IMPA and signs suggestive of spinal pain were described with regard to age, gender, breed, physical stature, location of vertebral pain, rectal temperature, and clinical laboratory findings. The prevalence of spinal pain in these dogs was 29% (18 of 62). Fourteen of the 18 dogs with spinal pain and IMPA were male. Cerebrospinal fluid (CSF) from 11 dogs with signs of spinal pain was analyzed. Five of these (46%) had concurrent steroid-responsive meningitis-arteritis (SRMA). We concluded that SRMA does occur concurrently in some dogs having IMPA. Meningeal involvement may explain the origin of spinal pain observed in some of these dogs.
