A 6-yr-old male snow leopard ( Panthera uncia) presented with acute seizures, hyperthermia, and tachypnea. Because of a diagnosis of anuric renal failure, the animal was euthanized. On histopathologic examination, numerous intralesional intracytoplasmic and intranuclear inclusions were found in the lungs, lymph nodes, and stomach. Positive immunohistochemical staining for canine distemper virus (CDV) was found in the lungs and, to a lesser extent, in the lymph nodes and brain. Molecular testing yielded a CDV H gene sequence that was closely related to CDV isolates concurrently found in wild raccoons from adjacent forested areas...

The nitroxyl (HNO) prodrug, CXL-1020, induces vasorelaxation and improves cardiac function in canine models and patients with systolic heart failure (HF). HNO's unique mechanism of action may be applicable to a broader subset of cardiac patients. This study investigated the load-independent safety and efficacy of CXL-1020 in two rodent (rat) models of diastolic heart failure and explored potential drug interactions with common HF background therapies. In vivo left-ventricular hemodynamics/pressure-volume relationships assessed before/during a 30 min IV infusion of CXL-1020 demonstrated acute load-independent positive inotropic, lusitropic, and vasodilatory effects in normal rats...

What is the central question of this study? In the present study, we investigated the effects of renal denervation on the vulnerability to ventricular fibrillation and the ventricular electrical properties in a rapid pacing-induced heart failure canine model. What is the main finding and its importance? Renal denervation significantly attenuated the process of heart failure and improved left ventricular systolic dysfunction, stabilized ventricular electrophysiological properties and decreased the vulnerability of the heart to ventricular fibrillation during heart failure...

Renal transplantation has become the preferred treatment for end stage kidney failure. Although short-term graft survival has significantly improved as advances in immunosuppression have occurred, long-term patient and graft survival have not. Approximately only 50% of renal transplant recipients are alive at 10 years due to the toxicities of immunosuppression and alloimmunity. Emerging research on cell-based therapies is opening a new door for patients to receive the organs they need without sacrificing quality of life and longevity because of drug-based immunosuppression...

Heart failure (HF) is a major health problem with worsening outcomes when renal impairment is present. Therapeutics for early phase HF may be effective for cardiorenal protection, however the detailed characteristics of the kidney in early-stage HF (ES-HF), and therefore treatment for potential renal protection, are poorly defined. We sought to determine the gene and protein expression profiles of specific maladaptive pathways of ES-HF in the kidney and heart. Experimental canine ES-HF, characterized by de-novo HF with atrial remodeling but not ventricular fibrosis, was induced by right ventricular pacing for 10 days...

PURPOSE: Safe, sensitive, and non-invasive imaging methods to assess the presence, extent, and turnover of myocardial fibrosis are needed for early stratification of risk in patients who might develop heart failure after myocardial infarction. We describe a non-contrast cardiac magnetic resonance (CMR) approach for sensitive detection of myocardial fibrosis using a canine model of myocardial infarction and reperfusion. METHODS: Seven dogs had coronary thrombotic occlusion of the left anterior descending coronary arteries followed by fibrinolytic reperfusion...

Paraquat is a bipyridylium non-selective contact herbicide commonly used worldwide. When ingestion occurs by humans and animals either accidentally, intentionally or maliciously, paraquat selectively accumulates in the lungs resulting in the production of oxygen-free radicals, causing membrane damage and cell death. Intoxicated subjects typically show progressive and fatal pulmonary haemorrhage, collapse and oedema. In individuals surviving the acute phase, pulmonary fibrosis develops. Gastrointestinal-, renal- and central nervous system clinical signs may also occur...

OBJECTIVE: Canine babesiosis is a common and clinically significant tick-borne disease caused by haemoprotozoan parasites of the genus Babesia. Acute renal failure is considered to be one of the most prevalent complications of canine babesiosis. This complication leads to a decrease in the glomerular filtration rate and in consequence causes azotemia and uremia. The objective of this study was to assess the localization and extent of renal damage in dogs infected with Babesia canis using an urinary marker for glomerular (urinary immunoglobulin G, uIgG), proximal tubular dysfunction (urinary retinol binding protein, uRBP) and distal tubular dysfunction (urinary Tamm-Horsfal protein, uTHP)...

BACKGROUND: Left atrial (LA) compliance and contractility influence left ventricular stroke volume. We hypothesized that diminished LA compliance and contractile function occur early during the development of heart failure with preserved ejection fraction (HFpEF) and impair overall cardiac performance. METHODS AND RESULTS: Cardiac magnetic resonance imaging, echocardiography, left ventricular and LA pressure-volume studies, and tissue analyses were performed in a model of early HFpEF (elderly dogs, renal wrap-induced hypertension, exogenous aldosterone; n=9) and young control dogs (sham surgery; n=13)...

BACKGROUND: Dirofilaria repens is a mosquito-transmitted, filarial nematode parasitizing dogs, cats and other carnivores. Recently, this parasite has spread in central Europe, including Poland. The aim of the present study was to estimate the prevalence of D. repens in cats and dogs in different regions of the country and to investigate the occurrence and consequences of co-infection with another fast-spreading vector-borne parasite, Babesia canis. RESULTS: In the period 2013-2015, 147 blood samples from cats from central Poland and 257 blood samples from dogs from central, northern, southern and western Poland were collected...

A 35-year-old woman was admitted to our hospital for evaluation of end-stage renal failure. Diagnostic imaging, including ultrasonography and magnetic resonance imaging, showed polycystic kidneys and peribiliary hepatic cysts, but the renal cysts were isointense and her kidneys were smaller than the end-stage kidneys of patients with autosomal dominant polycystic kidney disease. Glomerulocystic kidney disease was diagnosed by renal biopsy. Clinical examination revealed findings such as a missing maxillary canine, lingual anomalies, and brachydactyly...

Digitalis-like compounds (DLCs), the ancient medication of heart failure and Na,K-ATPase inhibitors, are characterized by their toxicity. Drug-drug interactions (DDIs) at absorption and excretion levels play a key role in their toxicity, hence, knowledge about the transporters involved might prevent these unwanted interactions. In the present study, the transport of fourteen DLCs with human P-glycoprotein (P-gp; ABCB1) was studied using a liquid chromatography-mass spectrometry (LC-MS) quantification method...

Ketamine, a dissociative anesthetic, is misused and abused worldwide as an illegal recreational drug. In addition to its neuropathic toxicity, ketamine abuse has numerous effects, including renal failure; however, the underlying mechanism is poorly understood. The process called epithelial phenotypic changes (EPCs) causes the loss of cell-cell adhesion and cell polarity in renal diseases, as well as the acquisition of migratory and invasive properties. Madin-Darby canine kidney cells, an in vitro cell model, were subjected to experimental manipulation to investigate whether ketamine could promote EPCs...

OBJECTIVES: The aim of this study was to determine if the atrial natriuretic peptide (ANP) precursor proANP is biologically active compared with ANP and B-type natriuretic peptide (BNP). BACKGROUND: ProANP is produced in the atria and processed to ANP and activates the guanylyl cyclase receptor-A (GC-A) and its second messenger, cyclic guanosine monophosphate (cGMP). ProANP is found in the human circulation, but its bioavailability is undefined. METHODS: The in vivo actions of proANP compared with ANP, BNP, and placebo were investigated in normal canines (667 pmol/kg, n = 5/group)...

OBJECTIVE: To explore the role of renal sympathetic denervation (RSD) on ventricular substrate remodeling in dogs with pacing-induced heart failure (HF). METHODS: A total of 19 dogs were randomized into 3 groups of sham-operated control (n = 7), right ventricular pacing induction of HF (n = 6) and RSD (n = 6). After 8-week pacing induction of HF. Hemodynamic variables were monitored at baseline and after HF. Masson's trichrome staining, enzyme-linked immunosorbent assay (ELISA) and Western blot were used to measure ventricular interstitial fibrosis, brain natriuretic peptide (BNP), angiotensin II (Ang II), aldosterone and transforming growth factor-beta (TGF-β)...

Chronic kidney disease is a major contributor to human and companion animal morbidity and mortality. Renal complications are sequelae of canine and human visceral leishmaniasis (VL). Despite the high incidence of infection-mediated glomerulonephritis, little is known about pathogenesis of VL-associated renal disease. Leishmania infantum-infected dogs are a naturally occurring model of VL-associated glomerulonephritis. Membranoproliferative glomerulonephritis type I [24 of 25 (96%)], with interstitial lymphoplasmacytic nephritis [23 of 25 (92%)], and glomerular and interstitial fibrosis [12 of 25 (48%)] were predominant lesions...
