Many etiological factors are involved in the pathogenesis of acute pancreatitis. The pathogenesis of acute pancreatitis has been attributed to such causes as trypsin autodigestion, pancreatic microcirculation malfunction, the calcium overload in pancreatic acinar cells, oxygen free radical injury, cytokine injury, and has been treated in detail in numerous reviews. More recently, heat shock proteins (HSP), particularly heat shock protein 60 (HSP60), have receive increasing attention as another possible factor in the pathogenesis and development of acute pancreatitis. This brief review aims to: (i) outline our current understanding of HSP and their role in pancreatitis; (ii) discuss the available evidences that suggest HSP's interplay between pancreas tissues and etiological agents; (iii) delineate the functional mechanisms of HSP proposed by different research groups, and offer new thinking in preventing and treating acute pancreatitis in general.

The effectiveness of a conservative approach in the management of groove pancreatitis.
Indian J Gastroenterol
January 2025
Department of Gastroenterology, Christian Medical College, Vellore, 632 517, India.
Background: Groove pancreatitis (GP) is a form of pancreatitis that affects the pancreaticoduodenal groove area, which lies between the head of the pancreas, the second part of the duodenum and the distal bile duct, presenting as abdominal pain and gastric outlet obstruction. In this study, we present the clinical and radiological characteristics of individuals diagnosed with groove pancreatitis at our center and discuss the use of a conservative treatment approach in managing GP.
Methods: The data of patients with groove pancreatitis treated at our center between January 2012 and December 2021 was analyzed.

Pancreatic ductal adenocarcinoma during pregnancy is extremely rare. Overall, including our case, only 19 cases confirmed antepartum have been reported to date. We report the case of a 37 year-old woman at 24 weeks of pregnancy in whom a pancreatic adenocarcinoma was identified during investigation of a suspected acute pancreatitis.

Quiescent pancreatic stellate cells (PSCs) represent only a very low proportion of the pancreatic tissue, but their activation leads to stroma remodeling and fibrosis associated with pathologies such as chronic pancreatitis and pancreatic ductal adenocarcinoma (PDAC). PSC activation can be induced by various stresses, including acidosis, growth factors (PDGF, TGFβ), hypoxia, high pressure, or intercellular communication with pancreatic cancer cells. Activated PSC targeting represents a promising therapeutic strategy, but little is known regarding the molecular mechanisms underlying the activation of PSCs.

Background: Post-pancreatectomy acute pancreatitis (PPAP) is an early acute inflammatory process of the pancreatic remnant that is associated with a series of downstream pancreas-specific complications. This study aimed to investigate the relationship between postoperative serum C-reactive protein (CRP) levels and the occurrence of PPAP after pancreaticoduodenectomy (PD).
Methods: Consecutive patients who underwent PD between January 1, 2020, and May 31, 2022, were retrospectively analyzed.
