The aim of the present study was to investigate the role of the angiotensin-converting enzyme (ACE)2-angiotensin‑(Ang)-(1-7)-Mas axis in the pathogenesis of pancreatitis and the association between this axis and the p38 mitogen-activated protein kinase (p38 MAPK)/nuclear factor (NF-κB) signaling pathway in pancreatic acinar cells. Mouse pancreatic acinar cancer (MPC-83) cells were stimulated with 10 nM caerulein (CAE) to create an in vitro model of acute pancreatitis, and collected for analysis at 2, 6, 12, 24 and 48 h post stimulation...

Most cases of acute pancreatitis are related to gallstones. More than 80% resolve within a few days. The diagnosis is based on upper abdominal pain, elevated lipase and/or amylase, and transabdominal ultrasound findings. Management requires early aggressive hydration, pain control, nutritional support, and monitoring for progression. Patients who develop hypovolemia, systemic inflammatory response, pancreatic necrosis, and organ failure have high mortality, risk of recurrence, and progression to chronic pancreatitis (CP)...

The pathogenic infectious pancreatic necrosis virus (IPNV) causes high economic losses in fish farming. This virus can modulate several cellular processes during infection, but little is known about the infection mechanism. To investigate gene activation in response to IPNV, CHSE/F and SHK-1 cell line were infected with a cytopathic Sp field isolate of IPNV, and the expression profiles of proinflammatory, antiviral cytokine, and extracellular matrix markers were analyzed. IPNV induced the production of perlecan, fibulin-1, matrix metalloproteinase-2, 14-3-3β, interleukin-1β, Mx1, and interferon regulatory factors-1, -3, and -9...

Acute necrotizing pancreatitis is a prevalent disease with high morbidity and mortality. The development of radiologic and endoscopic techniques to manage pancreatic necrosis commands a multidisciplinary approach, which has considerably decreased the need for laparotomy. The objective of this update is to define the role of surgery in the multidisciplinary approach to management of necrotizing acute pancreatitis.

Pancreatic cancer cells (PCCs) interact with pancreatic stellate cells (PSCs), which play a pivotal role in pancreatic fibrogenesis, to develop the cancer-conditioned tumor microenvironment. Exosomes are membrane-enclosed nanovesicles, and have been increasingly recognized as important mediators of cell-to-cell communications. The aim of this study was to clarify the effects of PCC-derived exosomes on cell functions in PSCs. Exosomes were isolated from the conditioned medium of Panc-1 and SUIT-2 PCCs. Human primary PSCs were treated with PCC-derived exosomes...

BACKGROUND: Infected necrotising pancreatitis is a potentially lethal disease and an indication for invasive intervention. The surgical step-up approach is the standard treatment. A promising alternative is the endoscopic step-up approach. We compared both approaches to see whether the endoscopic step-up approach was superior to the surgical step-up approach in terms of clinical and economic outcomes. METHODS: In this multicentre, randomised, superiority trial, we recruited adult patients with infected necrotising pancreatitis and an indication for invasive intervention from 19 hospitals in the Netherlands...

Wei Hu, Xuefeng Jia, Yanfang Gao, Qiujie Zhang
The pancreatic cancer is one of the most aggressive tumors. Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) can trigger apoptosis by interaction with death receptors. However, in TRAIL-resistant pancreatic cancer, responsiveness to TRAIL treatment is terribly poor. In current work, we have demonstrated that a natural product chaetospirolactone (CSL) isolated from an endophytic fungus Chaetomium sp. NF00754 can enhance the susceptibility of TRAIL-resistant pancreatic cancer cells to apoptosis...

Pancreatic necrosectomy (PN) following percutaneous catheter drainage (PCD) is an effective method of treating patients with necrotizing pancreatitis, however, the predictive factors for PN after PCD have not yet been identified. A total of 74 patients with suspected infected necrotizing pancreatitis (INP) and peripancreatic fluid collection were enrolled in the current study between October 2010 and October 2015. These patients received ultrasound or computer topography guided PCD followed by PN. Patients were divided into two groups: i) A PCD-alone group (n=32) and ii) a PCD+necrosectomy group (n=42)...

Pancreatic fluid collections are a frequent complication of acute pancreatitis. The revised Atlanta criterion classifies chronic fluid collections into pseudocysts and walled-off pancreatic necrosis (WON). Symptomatic PFCs require drainage options that include surgical, percutaneous, or endoscopic approaches. With the advent of newer and more advanced endoscopic tools and expertise, minimally invasive endoscopic drainage has now become the preferred approach. An endoscopic ultrasonography (EUS)-guided approach for pancreatic fluid collection drainage is now the preferred endoscopic approach...

BACKGROUND: Clinical and experimental acute pancreatitis feature histone release within the pancreas from innate immune cells and acinar cell necrosis. In this study, we aimed to detail the source of circulating histones and assess their role in the pathogenesis of acute pancreatitis. METHODS: Circulating nucleosomes were measured in patient plasma, taken within 24 and 48 h of onset of acute pancreatitis and correlated with clinical outcomes. Using caerulein hyperstimulation, circulating histones were measured in portal, systemic venous and systemic arterial circulation in mice, and the effects of systemic administration of histones in this model were assessed...

BACKGROUND: Emphysema is a progressive disease characterized by irreversible airspace enlargement followed by a decline in lung function. It also causes extrapulmonary effects, such as loss of body mass and cor pulmonale, which are associated with shorter survival and worse clinical outcomes. Ghrelin, a growth-hormone secretagogue, stimulates muscle anabolism, has anti-inflammatory effects, promotes vasodilation, and improves cardiac performance. Therefore, we hypothesized that ghrelin might reduce lung inflammation and remodelling as well as improve lung mechanics and cardiac function in experimental emphysema...

Acute pancreatitis is a fascinating disease. In the United States, the two most common etiologies of acute pancreatitis are gallstones and excessive alcohol consumption. The diagnosis of acute pancreatitis is made with a combination of history, physical examination, computed tomography scan, and laboratory evaluation. Differentiating patients who will have a benign course of their pancreatitis from patients who will have severe pancreatitis is challenging to the clinician. C-reactive protein, pro-calcitonin, and the Bedside Index for Severity of Acute Pancreatitis appeared to be the best tools for the early and accurate diagnosis of severe pancreatitis...

Pancreatic ductal adenocarcinoma is one of the leading causes of cancer-related deaths. With surgical resection being the only definitive treatment, improvements in technique has led to an increase in number of candidates undergoing resection by inclusion of borderline resectable disease patients to the clearly resectable group. Post-operative complications associated with pancreaticoduodenectomy and distal pancreatectomy include delayed gastric emptying, anastomotic failures, fistula formation, strictures, abscess, infarction, etc...
