Background: The prevalence of uremic hypothermia (UH) and the effects of improving uremia on body temperature have not been determined in veterinary patients.Objectives: To determine the prevalence of UH and correlations between uremia and body temperature in patients undergoing intermittent hemodialysis (IHD).Animals: Uremic dogs (n = 122) and cats (n = 79) treated by IHD at the Bobst Hospital of the Animal Medical Center from 1997 to 2013.Methods: Retrospective review of medical records.Results: The prevalence of hypothermia was 38% in azotemic cats and 20.5% in azotemic dogs. Statistically significant temperature differences were observed between uremic and nonuremic dogs (nonuremic: mean, 100.8°F; range, 91.2-109.5°F; uremic: mean, 99.9°F; range, 95.6-103.8°F; P < .0001) and cats (nonuremic: mean, 100.6°F; range, 94.0-103.8°F; uremic: mean, 99.3°F; range, 92.3-103.4°F; P < .0001). In dog dialysis patients, significant models included (1) timing (pre-dialysis versus post-dialysis) with weight class (small [P < .0001], medium [P = .016], and large breed [P = .033] dogs), (2) timing with serum creatinine concentration (P = .021), and (3) timing with BUN concentration (P < .0001). In cat dialysis patients, there was a significant interaction between timing and weight as a categorical variable (<5 kg and ≥5 kg).Conclusions and Clinical Importance: Uremic hypothermia appears to be a clinical phenomenon that occurs in cats and dogs. Uremic patients are hypothermic compared to ill nonuremic patients and body temperatures increase when uremia is corrected with IHD in dogs and in cats >5 kg. In cats, UH seems to be a more prevalent phenomenon driven by uremia. Uremic hypothermia does occur in dogs, but body weight is a more important predictor of body temperature.

“…Uremic hypothermia also is addressed in the veterinary literature, albeit less directly. A retrospective study evaluating rectal temperatures of male cats with urethral obstruction found that BUN and serum creatinine concentrations were significantly higher in the hypothermic group . Another study investigating prognostic factors for cats with AKI found lower body temperature to be a useful predictor of death .…”

Background Urethral obstruction (UO) is a common complication of feline idiopathic cystitis (FIC). Robust treatment recommendations to prevent its recurrence are scarce. Objectives To evaluate meloxicam treatment for prevention of clinical recrudescence in male cats with obstructive FIC. Animals Fifty‐one client‐owned cats. Methods Prospective, randomized clinical trial. Every male cat with FIC‐associated UO was deemed eligible for the study and was recruited during hospitalization. After discharge, cats were treated with phenoxybenzamine and alprazolam for 2 weeks, with (24 cats) or without (27 cats) low‐dose meloxicam (0.025 mg/kg/day PO) and monitored for 6 months. Results Cumulative number (%) of cats with recurrent UO at 10 days, 1‐, 2‐, and 6‐months after discharge was 1 (2%), 2 (4%), 4 (8%), and 8 (16%), respectively. Overall, 12 (24%) cats experienced signs of recurrent FIC within 6 months, with (8 cats) or without (4 cats) concurrent UO. No difference in the cumulative incidence of UO within 6 months was detected with addition of meloxicam (odds ratio [95% confidence interval], 0.63 [0.13‐2.97]; P = .70). All cats were alive at 6 months. Conclusions and Clinical Importance No clinical benefit was detected with the addition of low‐dose meloxicam to phenoxybenzamine and alprazolam treatment for 2 weeks after discharge. Nevertheless, this study was underpowered to identify potential differences, and its findings must be corroborated in larger studies.

Retrospective evaluation of presenting temperature of urethral obstructed male cats and the association with severity of azotemia and length of hospitalization: 243 cats (2006–2009)

Abstract: No association with regard to rectal temperature and LOH could be demonstrated in this population of cats. However, the presence of azotemia in obstructed male cats appears to provide the clinician with additional information regarding the necessary LOH and eventual cost to the client.
