AI Article Synopsis
- Chemokines, particularly MCP-1, are important in the development of acute pancreatitis, with acinar cells producing MCP-1 during inflammation.
- Blocking chemokine production is a key strategy for treating inflammatory diseases like acute pancreatitis.
- The study found that bindarit effectively reduced MCP-1 levels and offered significant protection against acute pancreatitis in mice, evidenced by lower enzyme levels and reduced tissue injury.
Article Abstract
Chemokines are believed to play a key role in the pathogenesis of acute pancreatitis. We have earlier shown that pancreatic acinar cells produce the chemokine monocyte chemotactic protein (MCP)-1 in response to caerulein hyperstimulation, demonstrating that acinar-derived MCP-1 is an early mediator of inflammation in acute pancreatitis. Blocking chemokine production or action is a major target for pharmacological intervention in a variety of inflammatory diseases, such as acute pancreatitis. 2-Methyl-2-[[1-(phenylmethyl)-1H-indazol-3yl]methoxy]propanoic acid (bindarit) has been shown to preferentially inhibit MCP-1 production in vitro in monocytes and in vivo without affecting the production of the cytokines IL-1, IL-6, or the chemokines IL-8, protein macrophage inflammatory-1alpha, and RANTES. The present study aimed to define the role of MCP-1 in acute pancreatitis with the use of bindarit. In a model of acute pancreatitis induced by caerulein hyperstimulation, prophylactic as well as therapeutic treatment with bindarit significantly reduced MCP-1 levels in the pancreas. Also, this treatment significantly protected mice against acute pancreatitis as evident by attenuated hyperamylasemia neutrophil sequestration in the pancreas (pancreatic MPO activity), and pancreatic acinar cell injury/necrosis on histological examination of pancreas sections.

Background And Aims: Gastric outlet obstruction (GOO) is a clinical manifestation of mechanical obstruction at the antropyloric region or proximal small bowel. The goal of endoscopic management is to relieve the obstruction so patients can resume per oral intake. Most studies have focused on malignant causes of GOO; yet only a handful have explored outcomes related to benign etiologies.

The traditional method of performing open common bile duct exploration (OCBDE) was replaced by a less invasive procedure known as laparoscopic common bile duct exploration (LCBDE) in elective surgery. But at present, the application of this technique is considered novel and controversial to treat acute cholangitis (AC). The aim of our systematic review was to investigate the safety and efficacy of laparoscopic surgery in patients with AC.

Objectives: To estimate the incidence of cystic fibrosis; to evaluate the performance of the screening algorithms Immunoreactive Trypsinogen and Pancreatitis-Associated Protein (IRT/PAP) and the IRTxPAP product; to analyze the cut-off value for IRT, PAP, and IRTxPAP, and to establish a methodology for its ongoing evaluation; finally, to evaluate the quality of IRT and PAP measurements.
