Canine pancreatitis is a relatively common disorder, and its mortality rate remains high. However, prognostic factors for pancreatitis based on evidence are limited. Moreover, the relationship between changes in C-reactive protein (CRP) concentration-an important prognostic factor for human patients with acute pancreatitis-and the prognosis of dogs with pancreatitis has not been widely studied. Therefore, we examined prognostic factors for canine pancreatitis during the first medical examination and evaluated the usefulness of serial CRP measurements during hospitalization...

BACKGROUND: Ancylostoma spp. is one of the most prevalent canine intestinal nematode infections which usually causes subclinical disease in adult dogs and has zoonotic implications. Therefore, the aim of this study was to explore and evaluate the possible pathophysiological changes that Ancylostoma spp. could produce in female dogs naturally infected but without clinical signs of disease, by screening a wide variety of biochemical markers for potential changes. Samples of feces and blood of 45 dogs were collected and fecal flotation and zinc sulphate centrifugal flotation were performed...

Animal models of pancreatitis are useful for elucidating the pathogenesis of pancreatitis and developing and testing novel interventions. In this review, we aim to summarize the most commonly used animal models, overview their pathophysiology, and discuss their strengths and limitations. We will also briefly describe common animal study procedures and refer readers to more detailed protocols in the literature. Although animal models include pigs, dogs, opossums, and other animals, we will mainly focus on rodent models because of their popularity...

Acute pancreatitis is an inflammatory process that frequently involves peripancreatic tissues and remote organ systems. It has high morbidity and mortality rates in both human and veterinary patients. The severity of pancreatitis is generally determined by events that occur after acinar cell injury in the pancreas, resulting in elevated levels of various proinflammatory mediators, such as interleukin (IL) 1β and 6, as well as tumor necrosis factor alpha (TNF-α). When these mediators are excessively released into the systemic circulation, severe pancreatitis occurs with systemic complications...

BACKGROUND: Exenatide's effects on glucose metabolism have been studied extensively in diabetes but not in pre-diabetes. OBJECTIVE: We examined the chronic effects of exenatide alone on glucose metabolism in pre-diabetic canines. DESIGN AND METHODS: After 10 weeks of high-fat diet (HFD), adult dogs received one injection of streptozotocin (STZ, 18.5 mg/kg). After induction of pre-diabetes, while maintained on HFD, animals were randomized to receive either exenatide (n = 7) or placebo (n = 7) for 12 weeks...

Severe acute pancreatitis (SAP) is associated with systemic complications and high mortality rate in dogs. Mesenchymal stem cells (MSCs) have been investigated for their therapeutic potential in several inflammation models. The present study investigated the effects of canine adipose tissue-derived (cAT)MSCs in a rat model of SAP induced by retrograde injection of 3% sodium taurocholate solution into the pancreatic duct. cATMSCs labeled with dioctadecyl-3,3,3'-tetramethylindo-carbocyanine perchlorate (1 × 10(7) cells/kg) were systemically administered to rats and pancreatic tissue was collected 3 days later for histopathological, quantitative real-time PCR, and immunocytochemical analyses...

Although dogs with acute necrotizing pancreatitis (ANP) can develop respiratory complications, there are no data describing lung injury in clinical cases of ANP in dogs. Therefore, we conducted a study to characterize lung injury and determine if pulmonary intravascular macrophages (PIMs) are induced in dogs with ANP (n = 21) compared with control dogs (n = 6). Two pathologists independently graded histologic sections of pancreas from clinical cases to characterize the severity of ANP (total scores of 3-10) compared with controls showing histologically normal pancreas (total scores of 0)...

Thrombomodulin (TM) is a membrane glycoprotein expressed on endothelial cells, which plays a major role in the protein C anticoagulation pathway. In people with inflammation, TM expression can be down-regulated on endothelial cells and a soluble form released into circulation, resulting in increased risk of thrombosis and disseminated intravascular coagulation. TM is present in dogs; however, there has been minimal investigation of its expression in canine tissues, and the effects of inflammation on TM expression in canine tissues have not been investigated...

The aim of the present study was to investigate the pancreatic exocrine function in a canine model and to analyze the changes in organelles of pancreatic acinar cells during the early stage of acute pancreatitis (AP). AP was induced by retrograde injection of 5% sodium taurocholate (0.5 ml/kg) into the main pancreatic duct of dogs. The induction of AP resulted in serum hyperamylasemia and a marked reduction of amylase activity in the pancreatic fluid (PF). The pancreatic exocrine function was markedly decreased in subjects with AP compared with the control group...

BACKGROUND: Diagnosis of pancreatitis in dogs is complicated by extrapancreatic disorders that can alter the results of laboratory tests. Extrapancreatic disorders can also affect the diagnosis of exocrine pancreatic insufficiency (EPI). The effects of acute kidney injury (AKI) on pancreas-specific lipase activity (Spec cPL(®) Test), serum lipase activity and trypsin-like immunoreactivity (TLI) in dogs have not been evaluated. HYPOTHESIS/OBJECTIVES: Serum Spec cPL, lipase activity, and TLI concentrations will increase secondary to decreased kidney function...

In experimental studies the sequence of vitals series lesion is established at various forms of acute experimental pancreatitis (edematous pancreatitis, a pancreatonecrosis). It is shown that one of the first in pathological process involves an intestine, then - a liver, further - kidneys. It is established that at acute pancreatitis the basis of a target organs lesion is membranodestruktivny process due to excess activity of lipids peroxidation processes and phospholipase systems which are registered not only in a blood plasma, but also in tissue structures of the studied organs - an intestine, a liver, kidneys (systemic distress damages of oxidative and phospholipase induced character) acts...

Animals treated with anticonvulsant drugs may have increased canine pancreas-specific lipase (cPLI) values. Inflammatory conditions and specifically acute pancreatitis are of major concern in these animals. Elevation in C-reactive protein is being associated with inflammatory status in dogs and it has been correlated with the clinical severity of pancreatitis. In the present study, we investigated if there is a correlation between the cPLI increase, changes in C-reactive protein and hepatic enzymes, as well as the incidence of severe acute pancreatitis (AP) in dogs with anticonvulsant treatment (phenobarbital, or potassium bromide or both)...

prevents, in pancreocytes, the evolving of a "supramaximalecbolic-stimulation" process. The PP involvement as a modulating agent of pancreon's reactivity is reflected by the progressive increment of its plasma values in the first week of an evolving AP episode. In the AP associated to a large meal, an overpowering of the pancreon's brake might have a pivotal role. In experimental and clinical chronic alcoholism, a vagal neuropathy of the Pavlov inhibitory fibers that, as a consequence, impairs the pancreon's brake through a depression of PP secretion is at the basis of an enhanced reactivity of the duodeno-pancreatic reflexes...

OBJECTIVE: The aim of this study was to investigate the influence of the greater splanchnic nerve (GSN) transection on the pathophysiological process of acute necrotizing pancreatitis (ANP). METHODS: The dogs were divided into a sham operation (SO) group, ANP group, and ANP with bilateral GSN transection (GSNT) group. Dogs in the GSNT group underwent bilateral GSNT immediately after ANP induction. The levels of serum pancreatic amylase (AMY), calcium, high-sensitivity C-reactive protein (HCRP), tumor necrosis factor α (TNF-α), interleukin 10 (IL-10), and neutrophile granulocyte (NEU) counts were monitored dynamically, and the pathological examinations of the pancreas was performed at postoperative day 7...

Pancreatitis is the most frequent disease affecting the exocrine pancreas in dogs and reliable diagnostic techniques for predicting fatal complications are lacking. Contrast-enhanced ultrasound (CEUS) improves detection of tissue perfusion as well as organ lesion vascular pattern. Objectives of this prospective case control study were to compare perfusion characteristics and enhancement patterns of the pancreas in healthy dogs and dogs with pancreatitis using CEUS. Ten healthy dogs and eight dogs with pancreatitis were selected based on physical examination, abdominal ultrasound, and blood analysis findings...

Babesia rossi is the cause of a highly virulent multisystemic disease with a variable outcome, which is a reliable model of systemic inflammatory response syndrome (SIRS). The objective of this study was to determine the concentration of canine pancreatic-specific lipase (cPL) in a population of dogs with naturally acquired B. rossi infection. In addition, the associations between serum cPL and death and SIRS status were examined. An observational study recruited 87 dogs diagnosed with B. rossi infection and serum cPL concentrations were measured daily until discharge or death...
