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.

Doença do trato inferior (DITUI) em felinos doméstico

Lower urinary tract disease (LUTD) is a multifactorial disease, wich may be caused by uroliths and calculations, bacterial and viral infections and anatomical abnormalities, among others. The disease can also be of unknown origin in wich case it is called intersticial cystitis. Knowing that the disease may have many causes, it is necessary to know the exact etiology and the best method of diagnosis, to establish specific therapeutic measures for each case. The diagnostic methods most commonly used are: urinalysis, radiography and ultrassonography, but the blood count and biochemistry can be used, trying to assess the overall status of the animal. The terapy used depends on the causative agent of disease, wich may include changes in supply until emergency treatment, azotemia in cats with post-renal. The present study aims to present a complete study of a disease, addressing it’s etiology, diagnosis and treatment, with particular attention to first item

Métodos diagnóstico de Hiperadrenocorticismo canina

The Hyperadrenocorticism is a disease that occur in dogs between mead to old age, is associated with the higher level of glucocorticoid that result in a corporal reaction. To make a diagnostic of this disease is necessary have a good history and physical examination, the principals complains of the proprietary are polyuria, polydipsia and polyphagia, in some times abdominal enlargement and lethargy. In the physical examination is observed this abdominal enlargement, hepatomegaly, alopecia, in some cases pyoderma and difficult respiratory. From this documents is possible determinate the differential diagnostics and with the tests find the diagnostic of the disease that the animal have. The base methods are hemogram, biochemical, urinalysis, radiographs and ultrasonography it’s possible do tomography and magnetic resonance too. There are confirmation methods too, they are very important, because the others not have documents necessary for the final diagnostic. Those are Urine cortisol to creatinine ratio, dexamethasone suppression test with high dose or low dose and ACTH stimulation test. Despite those tests have high sensibility and specificity, they can result in false positive or false negative, this is one of the causes to do the base methods and together make the veterinary doctor find the solution of the diagnostic and do the adequate treatment

Bilateral hydronephrosis and hydroureter after ovariohysterectomy using nylon cable tie: a case report

A spayed crossbred female dog was presented due to progressive weight loss, emesis and anorexia over the preceding month. A complete blood count, urinalysis, serum biochemical panel, and ultrasound were initially performed. Computed tomography urography was performed as a complementary exam. Based on ultrasound and CT findings an exploratory celiotomy was performed to remove hyperdense structures that could be the cause of the hydronephrosis and hydroureter in both kidneys. An extensive granulomatous reaction was found near the caudal pole to the left kidney. A nylon cable tie adhering firmly to this tissue was removed during surgical excision. On the dorsal surface of the bladder an extensive granulomatous reaction that had entrapped the right ureter was also noted. Another nylon cable tie was removed and the ureter was released. Eight months postoperatively, the dog was in good general physical condition, showing appetite and vigour. Abdominal ultrasonography showed improvement of the hydronephrosis in both kidneys. The urea ratio was normal, but the creatinine level was slightly elevated, suggesting a guarded prognosis. Thus, bilateral hydronephrosis as observed in the present study should be considered as a major complication after elective ovariohysterectomy.
