Glomerular disease was diagnosed by histopathologic examination in 11 related Bullmastiff dogs, and clinical and laboratory data were collected retrospectively. Four female and seven male dogs between the ages of 2.5 and 11 years were affected. Clinical signs, including lethargy and anorexia, were nonspecific and occurred shortly before death or euthanasia. In five affected dogs serial blood samples were obtained, and dramatically elevated blood urea nitrogen and creatinine levels were demonstrated up to 2.75 years before death. Protein-creatinine ratios were elevated in six of six dogs and were above normal 3.5 years before death in one dog. The kidneys appeared grossly normal to slightly smaller than normal at necropsy. Histologic abnormalities of the kidneys were consistent with chronic glomerulonephropathy with sclerosis. Examination of the pedigrees of related affected dogs yielded evidence supporting an autosomal recessive mode of inheritance.

Hyperadrenocorticism is a common endocrinopathy which results from the excessive production of cortisol by the adrenal cortex. In the majority of cases, this increased secretion of cortisol results from stimulation of the adrenal cortex by adrenocorticotrophic hormone secreted from the pituitary gland. In a smaller number of cases adrenal tumours are present. Clinical signs are variable but commonly include polydipsia and polyuria, polyphagia, obesity, a pendulous abdomen, hepatomegaly, alopecia, lethargy, weakness and anoestrus. Haematology, serum chemistry analysis and urinalysis should be performed on a dog with suspected hyperadrenocorticism. Finding a significant number of changes that are consistent with hyperadrenocorticism often allows a presumptive diagnosis to be made. Other tests can then be used to confirm the diagnosis and to help localise the cause, including liver biopsy, radiology, ultrasonography, gamma camera imaging, computed tomography, and measurement of blood and urine hormone levels. The ACTH stimulation test, low dose dexamethasone suppression test and measurement of the urine cortisol:creatinine ratio are used to assess whether hyperadrenocorticism is present. The high dose dexamethasone suppression test, measurement of plasma ACTH, corticotropin-releasing hormone stimulation test, and a modification of the urinary cortisol:creatinine ratio test are then implemented to determine the aetiology. The treatment of choice for adrenal neoplasia is surgical removal of the affected adrenal. On the other hand, pituitary hyperplasia or neoplasia may be treated either surgically, by bilateral adrenalectomy or hypophysectomy, or medically. The drug which is chosen most commonly for medical management is 1,1-dichloro-2(O-chlorophenyl)-2-(P-chlorophenyl) ethane (op'-DDD), which can be used to suppress adrenal function or to completely destroy the adrenal cortex. The antifungal agent ketoconazole also suppresses adrenal steroid synthesis and provides an alternative form of medical treatment for hyperadrenocorticoid dogs.

A review of records from the AnTox database of the American Society for the Prevention of Cruelty to Animals Animal Poison Control Center identified 43 dogs that developed increased blood urea nitrogen concentration, serum creatinine concentration, or both as well as clinical signs after ingesting grapes, raisins, or both. Clinical findings, laboratory findings, histopathological findings, treatments performed, and outcome were evaluated. All dogs vomited, and lethargy, anorexia, and diarrhea were other common clinical signs. Decreased urine output, ataxia, or weakness were associated with a negative outcome. High calcium x phosphorus product (Ca x P), hyperphosphatemia, and hypercalcemia were present in 95%, 90%, and 62% of the dogs in which these variables were evaluated. Extremely high initial total calcium concentration, peak total calcium concentration, initial Ca x P, and peak Ca x P were negative prognostic indicators. Proximal renal tubular necrosis was the most consistent finding in dogs for which histopathology was evaluated. Fifty-three percent of the 43 dogs survived, with 15 of these 23 having a complete resolution of clinical signs and azotemia. Although the mechanism of renal injury from grapes and raisins remains unclear, the findings of this study contribute to an understanding of the clinical course of acute renal failure that can occur after ingestion of grapes or raisins in dogs.

A 39-yr-old male with hepatorenal syndrome type 1 and refractory ascites was treated with continuous renal replacement therapy (CRRT) resulting in clinical improvement. He was positive for antibodies to hepatitis B, C, and human immunodeficiency viruses, and had a history of chronic alcohol and iv drug abuse. The patient had 4 hospital admissions during a 12-wk period. He first presented with advanced liver disease including pedal edema and a serum ammonia level of 56 micromol/L (reference range: 11 - 35 micromol/L). In subsequent admissions, he had asterixis, nausea, vomiting, jaundice, and worsening pedal edema. On his 4th admission, there was lethargy, tense ascites, decreased urinary output, bilateral edema of the lower extremities and scrotum, serum creatinine of 6.2 mg/dl (reference range: 0.6 - 1.5 mg/dl), and weight gain of 16 kg during the prior 8 wk. During the first 3 hospitalizations, he was treated with lactulose with slight improvement. On the 4th admission, he was started on low-dose dopamine (3 microg/kg/min) and 25% salt-poor albumin without clinical improvement. A pulmonary artery catheter was placed and hemofiltration by CRRT was performed for 5 days, with removal of 26.7 L of fluid and a net reduction of 11 kg of body weight. Serum creatinine decreased to 4.2 mg/dl during CRRT and was 2.2 mg/dl at hospital discharge 2 weeks later. His PaO(2) improved from 66 to 78 mmHg and his systemic vascular resistance increased from 571 to 799 dyne.sec/cm(5). CRRT was effective in relieving severe fluid retention and producing marked clinical improvement. We suggest that CRRT should be considered for the treatment of refractory ascites including that caused by hepatorenal syndrome.

A 5-year old Tinker gelding was referred to the Department of Equine Sciences with a left eye uveitis and fever. At presentation the horse showed a mild lethargy, fever and decreased vision of the left eye. Rectal examination revealed an enlarged left kidney, with a hard and an irregular surface. The cranial mesentery artery had an enlarged and irregular aspect. Blood analysis showed anaemia, leucocytosis, increased blood urea nitrogen and creatinine and a hyperproteinemia. Urine analysis repeatedly showed a marked proteinuria and an increased gammaGT/creatinine ratio. The amount of abdominal fluid was slightly increased. However, the aspect, amount of cells and protein were normal. In the following two days the fever persisted and the horse showed anorexia and severe neurological signs. The horse was euthanized with permission of the owner. Post mortem examination showed a generalized parasitic infestation of Halicephalobus gingivalis in the uvea of the left eye, the kidneys and the central nerve system.

Primary hyperparathyroidism is rarely produced by parathyroid carcinoma. We present the case of a 63-yr-old man who was admitted due to recent onset of constipation, weakness and progressive lethargy. At physical examination, a left cervical mass was palpated. Marked hypercalcemia (serum calcium 25 mg/dl) (6.22 mmol/l) complicated by renal insuficiency (serum creatinine 4.4 mg/dl) (388 micromol/l) was found, but both were unresponsive to conventional therapy and hemofiltration. Autopsy examination showed a carcinoma of the upper left parathyroid gland, multiple foci of metastatic calficications in the vessel walls and parenchyma of both lungs and kidneys, and the myocardium, which contributed to multi-organ failure and death. In addition to describing the clinical presentation, we review the mechanism of metastatic calcifications as well as the role of renal function and hyperphosphatemia, and the basis for therapy of hypercalcemic crisis.

Multiple mycloma causes a disproportionate amount of the malignancy-related renal insufficiency. Acute renal insufficiency in myeloma patients can occur due to dehydration, hypercalcemia, side effects of medications (NSAIDs) or tumor lysis syndrome in addition to cast nephropathy, amyloidosis and light chain deposition disease. Patients on hemodialysis have traditionally been excluded from antineoplastic therapy due to fear of side effects and lack of studies addressing benefit. Melphalan is the most effective chemotherapeutic agent in myeloma and its PK (pharmacokinetics) are not adversely affected by impaired renal function. Because of more pronounced toxicity of Melphalan 200 mg/m2 conditioning regimen, Melphalan 140 mg/m2 has become the standard of care. 24% of patients become dialysis-independent at a median of 4 months after autotransplantation. Favorable factors for becoming dialysis independent were duration of dialysis <or=6 months and pretransplant creatinine clearance >10 ml/min. While no good data are available on the use of thalidomide in the presence of renal failure, it is our experience that severe neuropathy, constipation, lethargy and bradycardia are more frequent in patients with creatinine >or=3 mg/dl. It has become apparent that bisphosphanates-zoledronic acid more than pamidronate-cause renal dysfunction. If patients remain dialysis-dependent after autotransplantation, we recommend to delay considering a renal transplant until at least 3 years after the first transplant.

We retrospectively studied seven children (six girls, one boy) aged from 7.5 to 25 months who presented to our institution after taking large doses of vitamin D (900 000-4 000 000 U) prescribed by medical practitioners for wrong indications like failure to thrive, etc. The clinical manifestations were constipation, decreased appetite, lethargy, polyuria, dehydration and failure to thrive. All patients had hypercalcemia (serum calcium ranging from 12 to 16.8 mg/dl), high 25[OH]D levels (ranging from 96 to >150 ng/ml), suppressed intact parathyroid hormone (ranging from <3 to 8.1 pg/ml). Hypercalciuria (urinary calcium/creatinine ranging from 1 to 2.45) was found in all patients, while nephrocalcinosis was present in five patients. All were treated with intravenous fluids, oral prednisolone, restriction of calcium in diet, while four patients received pamidronate infusion for reducing hypercalcemia.

Delirium may present with hyperactive, hypoactive or mixed clinical pictures. The signs of hypoactive delirium are lethargy, confusion, apathy, hypersomnia, muttering, difficulty in maintaining attention, and difficulty in understanding and performing commands. Valproate is commonly used for the treatment of epilepsy and bipolar disorders. It is also used for the management of alcohol withdrawal delirium and agitative-aggressive deliriums. However, few reports are available about the valproate-induced delirium. In this report, we present a 46 years-old woman with bipolar disorder for 14 years. During her last two hospital admissions, she had been diagnosed with manic episode with psychotic features and she had received valproate. She experienced three hypoactive delirium episodes lasting 2-3 days throughout the treatment period of first week. The patient predominantly had the following signs; vomiting, hypersalivation, confusion, drowsiness, dysphasia, and hypoactivity. At the first day of delirium episode, serum valproate level was found to be within the therapeutic range (98.4, 117.1, and 65.6 mug/ml; respectively). In addition, she had normal results of cranial MRI, complete blood count, urine analysis, electrocardiogram, ALT, AST, albumin, bilirubin, BUN, creatinine and electrolytes. The serum ammonia level of the patient could not been measured due to limitations of laboratory facilities. The patient's consciousness improved dramatically 2-3 days after cessation of valproate. In conclusion, valproate can induce delirium at therapeutic blood levels in some patients via various mechanisms and this side effect has to be considered during valproate use.
