This study evaluated the circulating levels of serum symmetric dimethylarginine (SDMA) in 12 dogs with different severities of heartworm disease (HWD) and assessed the biochemical renal markers (blood urea nitrogen, creatinine). Dogs were classified into 2 groups based on the severity of clinical signs. Group A - asymptomatic to mild clinical signs, group B - moderate to severe clinical signs. The serum SDMA levels were higher in dogs in group B. Although the serum SDMA levels in dogs in group A were also higher than those of the control dogs, the difference was not statistically significant. There was a good correlation between renal markers and severity of clinical signs. This study demonstrated that the glomerular filtration rate was significantly decreased in dogs in group A; therefore, earlier detection of renal impairment is required for successful management of dogs with HWD.
