Proficiency in the medical and surgical care of animals is a prerequisite for any practicing veterinarian. Equally important, but less emphasized in veterinary education, is proficiency in communicating the medical and surgical aspects of patient care to clients and the related activity of medical records keeping. A perceived failure in any of these areas, or in any other facet of clinical practice, may lead an owner to pursue legal recourse, such as a professional negligence or veterinary malpractice lawsuit, potentially leading to serious repercussions for the veterinarian in question.

Abstract

OBJECTIVE

To establish a reference interval for glomerular filtration rate (GFR) determined by measuring serum clearance of a single IV dose of inulin in clinically normal cheetahs (Acinonyx jubatus) and compare serum symmetric dimethylarginine (SDMA) concentration in cheetahs with GFR.

ANIMALS

33 cheetahs housed at 3 institutions.

PROCEDURES

A single bolus of inulin (3,000 mg/m2) was administered IV, and 5 serial blood samples were collected and analyzed for serum inulin concentration with the anthrone technique. The GFR was estimated with a modified slope-intercept method for the slow component of the serum concentration-versus-time curve. Blood urea nitrogen and serum creatinine concentrations were measured in samples obtained immediately prior to inulin administration, and serum SDMA concentration was measured in stored samples.

RESULTS

Mean ± SD measured GFR was 1.58 ± 0.39 mL/min/kg, and the calculated reference interval was 0.84 to 2.37 mL/min/kg. There were significant negative correlations between GFR and serum creatinine concentration (r = −0.499), BUN concentration (r = −0.592), and age (r = −0.463). Serum SDMA concentration was not significantly correlated with GFR (r = 0.385), BUN concentration (r = −0.281), or serum creatinine concentration (r = 0.165).

CONCLUSIONS AND CLINICAL RELEVANCE

A reference interval for GFR in clinically normal cheetahs was obtained. Further evaluation of animals with renal disease is needed to determine whether measuring serum clearance of a single IV dose of inulin is a reliable diagnostic test for early detection of renal disease in cheetahs.
