2018 ACVIM Forum Research Abstract Program: Seattle, Washington, June 14 - 15, 2018

Intra-and inter-run CV, percent recovery after spiking, and linearity of dilution were satisfactory. There were significant correlations between uNAG index and plasma creatinine (p-value < 0.05) and between uNAG index and FE Na (p-value < 0.01). Median uNAG indices were significantly higher (p-value < 0.05) in azotemic horses, in horses with increased FE Na , and in horses with increased uGGT index. Urinary NAG can be measured in horses and shows correlation with current biomarkers of renal dysfunction. Additional work is needed to determine the timing of increase in uNAG index relative to onset of kidney injury in horses and to evaluate clinical utility in equine patients. Twenty-eight cases were identified. Prevalence of UTI in our equine cases was 0.13% between 2009 and 2016. Trakehner and Holsteiner horses were significantly overrepresented compared to the hospital population (p < 0.05) and UTI were more frequent in females (p < 0.05). Urinary tract infections were associated with other diagnostics involving the urinary tract such as bladder emptying problems in 64% of the cases. Eighty-four bacteria were isolated from 54 cultures.
