BACKGROUND/OBJECTIVES: Respiratory dysfunction and/or failure from acute lung injury (ALI) are common in acute pancreatitis (AP), but assessment of ALI in experimental AP has lacked standardisation. METHODS: A range of experimental AP models induced in C57BL/6 mice with corresponding controls (n = 6/group). Full double lung or right lung specimens were taken for histopathological assessment and slides analysed by a pre-set pipeline using Aperio Scanner (Leica), ImageJ software and CellProfiler software...

We encountered a case of gemcitabine (GEM)-induced secondary thrombotic microangiopathy (TMA) with nephrotic syndrome. Advanced pancreatic cancer with liver metastasis had originally been diagnosed. Renal biopsy showed focal reduplication of the glomerular basement membrane, endothelial cell swelling, and narrowed capillary lumens with fragmented erythrocytes and fibrin deposition, compatible with TMA. Regular monitoring of renal function during GEM treatment and discontinuation of treatment if acute kidney injury (AKI) might occur is crucial, because AKI combined with TMA is life-threatening...

BACKGROUND Steroid receptor coactivator-interacting protein (SIP) inhibits the activation of nuclear factor-kappa B (NF-κB) by interacting with p65. The occurrence of acute pancreatitis (AP) is closely associated with pro-inflammatory response. The present study aimed to investigate the role of SIP on myocardial injury caused by AP. MATERIAL AND METHODS Rat pancreatic acinar tumor cell line AR42J cells were treated with caerulein to establish AP cell models. The levels of TNF-α, IL-6, cTnI, CK-MB, and LDH1 were detected by ELISA assay...

We present a case of a 60-year-old woman with extrahepatic cholangiocarcinoma and recurrent malignant biliary strictures status post placement of two overlapping distal bile duct uncovered self-expandable metal stents (SEMSs) who presented with biliary obstruction due to tumor/tissue ingrowth. She subsequently underwent radiofrequency ablation (RFA) through SEMS to improve biliary stent patency. Post-RFA, thermal injury was observed in the periampullary mucosa. She later developed acute pancreatitis. This is the first case of RFA-induced acute pancreatitis with endoscopic evidence of thermal injury...

Infection with genotype 1 or 2 hepatitis E virus (HEV) results primarily from human-to-human transmission through the fecal-oral route in low-resource countries. It presents primarily as "acute viral hepatitis" syndrome, usually a self-limiting illness. A few cases progress to acute liver failure, a serious illness with high fatality. Clinical disease is infrequent among children. Infection during pregnancy is associated with a higher risk of symptomatic disease, severe liver injury, and mortality...

Severe acute pancreatitis (SAP) associated acute lung injury (ALI) accounts for about 70% mortality of SAP patients. However, there are no precise biomarkers for the disease currently. Herein, we evaluated the potential of gamma-enolase (ENO2), against its universal isoform alpha-enolase (ENO1), as a marker of SAP-ALI in a rat model. Firstly, 16 male Sprague-Dawley rats were randomly divided into two groups, Sham (n = 8) and SAP-ALI (n = 8), for pancreatitis induction. Ultra-structure examination by electron microscopy and HE staining were used for lung injury assessment...

Cell-based therapy is emerging as a promising strategy for treating a wide range of human diseases, such as diabetes, blood disorders, acute liver failure, spinal cord injury, and several types of cancer. Pancreatic islets, blood cells, hepatocytes, and stem cells are among the many cell types currently used for this strategy. The encapsulation of these "therapeutic" cells is under intense investigation to not only prevent immune rejection but also provide a controlled and supportive environment so they can function effectively...

Severe acute pancreatitis (SAP) is a disease with a high mortality. Patients with SAP may also be complicated with acute lung injury (ALI). So far the therapy for SAP-ALI is still limited. Emerging evidences demonstrate that microRNAs (miRs) could play a role in SAP-ALI. This study aims to define the role of miR-339-3p in SAP-ALI via Anxa3 through the Akt/mTOR signaling pathway. Ten mice were selected as sham group and 36 mice as model group which further assigned into different groups. Relationship between miR-339-3p and Anxa3 was detected by dual luciferase reporter gene assay...

AIMS: Severe acute pancreatitis (SAP) is a serious disease associated with systematic inflammation and multiple organs dysfunction. Soluble ST2 (sST2), a member of the Toll interleukin (IL)-1 receptor (TIR) superfamily, has been demonstrated to exert immune-regulatory and anti-inflammatory properties in several inflammation-related diseases. In this study, we investigated whether transfer of sST2 gene by adenovirus vector could attenuate sodium taurocholate-induced SAP and associated cardiac injury...

BACKGROUND: Acute pancreatitis (AP) is a common inflammatory disease that may develop to severe AP (SAP), resulting in life-threatening complications. Impaired autophagic flux is a characteristic of early AP, and its accumulation could activate oxidative stress and nuclear factor κB (NF-κB) pathways, which aggravate the disease process. AIM: To explore the therapeutic effects of regulating autophagy after the onset of AP. METHODS: In this study, intraperitoneal injections of 3-methyladenine (3-MA) and rapamycin (RAPA) in the L-arginine or cerulein plus lipopolysaccharide (LPS) Balb/C mouse model...

BACKGROUND: Severe chronic kidney disease (CKD) predicts adverse outcomes in patients undergoing pancreatectomy, but the impact of milder CKD is unknown. Additionally, some authors have suggested that, due to physiologic changes of aging, CKD is over-diagnosed in patients above age 65. METHODS: Patients undergoing pancreatectomy for malignancy from 2005 to 2014 were identified from the National Surgical Quality Improvement Program. Primary outcomes were all-cause mortality and major complication, defined as myocardial infarction, cardiac arrest, stroke, venous thromboembolism, respiratory failure, deep surgical site infection, pneumonia, acute kidney injury, coma > 24 h, or re-operation occurring within 30 days of surgery...

Hepatitis E virus (HEV) is a significant public health problem that affects almost 20 million individuals annually and cause acute liver injury in 3,5 million. Hepatitis E virus can cause acute, fulminant and chronic hepatitis and has been associated with a range of extrahepatic manifestation. The spectrum of these manifestation is still emerging. Acute pancreatitis and neurological, renal, hematologic, and muscoloskeletal manifestations have been described. Renal injury include membranoproliferative glomerulonephritis with or without cryoglobulinemia, membranous glomerulonephritis and tubular necrosis...

Intravascular erythrocyte destruction, accompanied by the release of pro-oxidative and pro-inflammatory components hemoglobin and heme, is a common event in the pathogenesis of numerous diseases with heterogeneous etiology and clinical features. A frequent adverse effect related to massive hemolysis is the renal injury and inflammation. Nevertheless, it is still unclear whether heme--a danger-associated molecular pattern--and ligand for TLR4 or upstream hemolysis-derived products are responsible for these effects...

BACKGROUND: The plasticity of pancreatic acinar cells to undergo acinar to ductal metaplasia (ADM) has been demonstrated to contribute to the regeneration of the pancreas in response to injury. Sox9 is critical for ductal cell fate and important in the formation of ADM, most likely in concert with a complex hierarchy of, as yet, not fully elucidated transcription factors. RESULTS: By using a mouse model of acute pancreatitis and three dimensional organoid culture of primary pancreatic ductal cells, we herein characterize the Ets-transcription factor Etv5 as a pivotal regulator of ductal cell identity and ADM that acts upstream of Sox9 and is essential for Sox9 expression in ADM...
