Nonsteroidal anti-inflammatory therapy: changes on renal function of healthy dogs

PURPOSE: To evaluate the renal function in healthy dogs submitted to nonselective and preferential COX-2 nonsteroidal anti-inflammatory drug (NSAID) therapy. METHODS: Twenty four healthy dogs were distributed into four groups (G) (n=6): ketoprofenG - treated with ketoprofen; nimesulideG - treated with nimesulid; meloxicanG - treated with meloxican; and etodolacG - treated with etodolaco. All the dogs received the NSAIDs for 10 days by oral route. Physical examination and renal function (urinalysis, urinary sodium and gamma-glutamyl transpeptidase (GGT), serum urea, creatinine, potassium and sodium, and endogenous creatinine clearance) were evaluated before, after five and ten days (T0, T5 and T10) of the treatment in all groups. RESULTS: Changes were observed in urinalysis, with a significant increase in renal cells in the urine at T5 and T10 in nimesulideG. Significant reduction in urinary sodium in nimesulideG at T5 was observed. The clearance values were lower in ketoprofenG at T10. CONCLUSIONS: Meloxicam and etodolac were the drugs that have proven to be safer for short-term therapy in healthy dogs in relation to renal function. NSAIDs ketoprofen and nimesulide should be used judiciously in dogs with renal dysfunction, since there are promoted changes in renal function.

False positivity of gamma-glutamyl transpeptidase measurement in urine

Although enzymuria tends to be associated to renal injury, there are no studies that have evaluated the presence of the enzyme gamma-glutamyl transpeptidase (GGT) spectrophotometry in the urine using a non-nephrotoxic agent (Nerium oleander) in order to evaluate the possibility of false positive results. The urinary GGT/urinary creatinine concentration ratio (uGGT/uCr) of 10 healthy dogs was calculated and posteriorly confronted with data from clinical evaluation, hematological and serum biochemical profiles, creatinine clearance (CrC), urinalysis, urine protein/creatinine ratio (UPC), electrocardiogram, systemic blood pressure (SBP) and light and electron microscopy. The results for kidney histology, SBP, UPC and CrC were not significantly different in any of the time-points analyzed. However, uGGT/uCr was significantly higher when measured 4 hours and 24 hours after administration of N. oleander. The measurement of the urinary GGT enzyme, as performed in many studies, yielded false positive results in dogs poisoned by a non-nephrotoxic agent.

Pre- and post-operative evaluations of eight dogs following right nephrectomy due to Dioctophyma renale

Background: Dioctophyma renale is a large nematode distributed worldwide that may cause progressive and severe destruction of renal parenchyma.Objectives: The present study aimed to evaluate pre- and post-operatively dogs submitted to right nephrectomy due to D. renale and to assess the histopathological damage of the removed kidney.Animals and methods: Eight crossbred dogs, aged from 12 to 48 months that were unilaterally nephrectomized due to the presence of D. renale were evaluated. Physical examination, urinalysis, complete blood count, serum biochemistry, and abdominal ultrasound were performed immediately before and one month after nephrectomy. The nephrectomized right kidneys were submitted to macroscopic and microscopic evaluations.Results: Urinalysis preoperatively detected occult blood in all dogs and D. renale eggs in five cases. Complete blood count showed all parameters within the reference range, except one dog post-operatively. Serum biochemistry performed before and after surgery verified that urea, creatinine and sodium were within the reference range values in all dogs. Other findings varied among the dogs. The length and arterial resistive index mean values of the left kidney were similar pre- and post-operatively.Conclusions: Thus, the inconsiderable change in laboratory findings pre- and post-operatively was attributable to compensation by left kidney function for the removed abnormal right kidney. Right kidney histology revealed chronic nephropathy due to D. renale.Clinical importance: Imaging diagnosis should be performed on dogs suspected as carrying the disease or on those from an enzootic area since the laboratory findings are not specific except eggs in the urine.
