BACKGROUND AND PURPOSE: Nonsteroidal anti-inflammatory drugs (NSAIDs) are administered to manage pain typically found in patients suffering from pancreatitis. NSAIDs also display anti-proliferative activity against cancer cells, however their effects in normal, untransformed cells is poorly understood. Here we evaluated whether NSAIDs inhibit proliferation of pancreatic acinar cells during the development of acute pancreatitis. EXPERIMENTAL APPROACH: The NSAIDs ibuprofen and diclofenac were administered to C57BL/6 mice after induction of pancreatitis with serial injection of cerulein...

Hypertriglyceridemia (HTG) aggravates the course of acute pancreatitis (AP). Intestinal barrier dysfunction is implicated in the pathogenesis of AP during which dysbiosis of intestinal microbiota contributes to the dysfunction in intestinal barrier. However, few studies focus on the changes in intestine during HTG-related acute necrotizing pancreatitis (ANP). Here, we investigated the changes in intestinal microbiota and Paneth cell antimicrobial peptides (AMPs) in HTG-related ANP (HANP) in rats. Rats fed a high-fat diet to induce HTG and ANP was induced by retrograde injection of 3...

RATIONALE: IgG4-related disease (IgG4-RD) is a newly recognized systemic disease. The typical pathological finding in the kidney is abundant IgG4-positive plasma cell infiltration with characteristic storiform fibrosis in the interstitium. Antibodies of the IgG4 subclass have been linked to certain autoimmune diseases including antiproteinase 3 (PR3) anti-neutrophil cytoplasmic antibody (ANCA) of the IgG4 subclass. Here, we report a rare case of kidney injury with concurrent typical IgG4-related tubulointerstitial nephritis and IgG4 subclass of myeloperoxidase (MPO) ANCA-positive necrotizing crescentic glomerulonephritis...

Thrombotic microangiopathy (TMA) occurring after acute pancreatitis is rarely described. Without prompt intervention, TMA can be, and often is, lethal, so prompt recognition is important. Here, we present a case of a 61-year-old woman with a history of alcohol misuse who presented with epigastric pain, nausea and vomiting after binge drinking. Elevated serum lipase and imaging were suggestive of acute-on-chronic pancreatitis. Although the patient's symptoms of acute pancreatitis subsided, her anaemia, thrombocytopenia and acute kidney injury worsened...

The 5-hydroxytryptamine-3 receptor (5-HT3R) antagonist ondansetron has been clinically approved as an anti-emetic agent. Recent findings indicate that ondansetron has anti-inflammatory properties. The aim of the present study was to assess the therapeutic action of ondansetron in cerulein-induced acute pancreatitis model. Male-BALB/c mice were used in the present study. Acute pancreatitis was induced by an hourly injection of cerulein. Ondansetron was administered subcutaneously at a dose of 3 mg/kg. The messenger RNA (mRNA) expression of 5-HT3 R in pancreatic tissue was assessed with RT-PCR...

Case summary A 6-year-old, neutered female British Shorthair cat presented with acute-onset weakness and mental dullness. Initially the cat was mildly hyperglycaemic (9.9 mmol/l; reference interval [RI] 3.3-6.7 mmol/l). Over the following 12 h the cat developed central blindness, tremors, intermittent seizures and opisthotonus. Repeat blood sampling revealed a marked hypoglycaemia (0.8 mmol/l). Insulin level (performed on a serum sample collected while the cat was hypoglycaemic) was inappropriately elevated (1575 mIU/l; RI 10-80 mIU/l)...

Ipilimumab is a monoclonal antibody that exerts its effects by inhibiting the cytotoxic T-lymphocyte-associated protein 4 receptor on cytotoxic T lymphocytes. It is frequently used for the treatment of unresectable or metastatic melanoma. Ipilimumab may lead to several immune-related disease including colitis, thyroiditis, pneumonia, hepatitis, or pancreatitis as a side effect. Limited number of cases with hepatic damage as an ipilimumab-related adverse event has been reported in the literature. This agent has been implicated in causing acute hepatitis-like liver injury...

Acute pancreatitis (AP) is a commonly occurring gastrointestinal disorder. An increase in the annual incidence of AP has been observed, and it causes acute hospitalization and high mortality. The diagnosis and treatment guidelines for AP recommend conservative medical treatments focused on reducing pancreatic secretion and secondary injury, as a primary therapeutic approach. Unfortunately, the existing treatment options have limited impact on the incidence and severity of AP due to the complex and multifaceted pathological process of this disease...

Paraquat can lead to injury of multiple organs. As there is no specific treatment for paraquat poisoning, it represents a serious clinical problem. Antioxidants are required to treat oxidative stress in paraquat poisoning and paraquat-induced injury. In this study, we report on successful treatment of a rare case of epilepsy and acute pancreatitis caused by paraquat poisoning. A 29-year-old woman at our hospital presented with a 13-day history of nausea and vomiting after ingesting 20 mL of paraquat (20% W/V)...

Benign recurrent intrahepatic cholestasis (BRIC) is characterised by recurrent episodes of jaundice, severe pruritus and low or normal serum γ-glutamyltransferase activity lasting from several weeks to months. BRIC is an autosomal recessive disorder caused by the mutation in either of the two hepatic transporter genes-ATP8B1 or ABCB11 gene. The disease is very well known for episodic flare of jaundice with cholestatic symptoms that are spontaneous or perpetuated by acute insults, followed by self-recovery...

Cystic artery pseudoaneurysm is a rare pathology. Of the 20 cases reported so far, chronic cholecystitis and iatrogenic biliary injury form the majority of causes. Currently, there is no published report of such pseudoaneurysms caused secondary to pancreatitis, hence the management in such a scenario is unclear. We hereby present the first such report of cystic artery pseudoaneurysm occurring as a sequel of acute necrotising pancreatitis. A 33-year-old man who recovered from a recent attack of acute pancreatitis was readmitted for melena and fever...

OBJECTIVES: Intestinal barrier dysfunction plays an important role in acute necrotizing pancreatitis (ANP) and intestinal microbiota dysbiosis was involved in intestinal barrier failure. Paneth cells protect intestinal barrier and are associated with intestinal microbiota. Here, we investigated changes in intestinal microbiota and antimicrobial peptides of Paneth cells in ileum during ANP. METHODS: Rats with ANP were established by retrograde injection of 3.5% sodium taurocholate into biliopancreatic duct and sacrificed at 24h and 48h, respectively...

Dibutyltin dichloride (DBTC) is an organotin compound used as model for acute and chronic pancreatitis. Oxidative stress is one of the mechanisms of propagation of acinar cell injury in acute pancreatitis. Selenium is an essential cofactor in the antioxidant glutathione peroxidase pathway. Selenium levels are described to be subnormal in patients with acute and chronic pancreatitis. The aim of our studies was to determine the prophylactic effect of Na-selenite [5 mg kg(-1) body weight (b.w.) per os (p.o.) 7 days] on the pathogenesis and course of DBTC- induced pancreatitis...

Severe acute pancreatitis (SAP) starts as a local inflammation of pancreatic tissue that induces the development of multiple extrapancreatic organs dysfunction; however, the underlying mechanisms are still not clear. Ischemia-reperfusion, circulating inflammatory cytokines, and possible bile cytokines significantly contribute to gut mucosal injury and intestinal bacterial translocation (BT) during SAP. Circulating HMGB1 level is significantly increased in SAP patients and HMGB1 is an important factor that mediates (at least partly) gut BT during SAP...

Pancreatitis is a gastrointestinal disease with a worldwide sharp surge during the past decade. Pancreatitis includes acute and chronic subtypes, which are graded based on the amount of pancreatic inflammation. Phytoconstituents represent a promising class of therapeutic agents with wide acceptability not only based on folk practices but sound presence of pharmacological and molecular evidences. Growing research evidence indicates that different molecular mechanisms are involved in their protective effect. Many phytoremedies have been tried for the treatment of pancreatic injuries and have shown success in preclinical animal models of pancreatitis...
