C-reactive protein concentration in dogs with inflammatory leukograms.

Abstract

Serum C-reactive protein (CRP) concentration was measured, using an automated immunoturbidimetric assay, in 44 clinically normal dogs and 67 dogs with band neutrophil count > or = 10(9) cells/L, and values were found to be significantly (P < or = 0.05) different. Correlation of serum CRP concentration and band neutrophil count in the 67 dogs with > or = 10(9) band neutrophils/L resulted in a statistically significant (P < or = 0.05), but low correlation coefficient of 0.34. Serum CRP concentration and CBC values were determined for 6 clinically normal dogs undergoing anesthesia (controls) and 6 clinically normal dogs undergoing anesthesia and ovariohysterectomy. Significant alterations in CBC results and serum CRP concentration, compared with baseline values, were lacking in dogs of the control group. Serum CRP concentration was significantly (P < or = 0.05) increased above baseline values in dogs undergoing surgery and was significantly (P < or = 0.05) increased, compared with values in control dogs by 12 hours after surgery. In dogs undergoing surgery, serum CRP concentration was also significantly (P < or = 0.05) different from values in control dogs at 28 and 36 hours, but not at the 76- and 124-hour sample collection times. Alterations in CBC values compatible with possible or convincing inflammation were detected in 83% of the dogs undergoing surgery at the 8- and 12-hour postsurgery sample collection times, 100% of dogs at 16, 22, 28, and 36 hours after surgery, 83% of dogs at 52 and 76 hours after surgery, 67% of dogs at 100 hours after surgery, and 0% of dogs at 124 hours after surgery.(ABSTRACT TRUNCATED AT 250 WORDS)
