Acute lung injury (ALI) and its severe form, acute respiratory distress syndrome (ARDS), remain the leading causes of morbidity and mortality in intensive care units. Ulinastatin (UTI), a serine protease inhibitor, possesses anti-inflammatory properties and has been suggested to modulate lipopolysaccharide (LPS)-induced sepsis; thus, it is now widely used in the treatment of pancreatitis, sepsis, and septic shock. Toll-like receptor 4 (TLR4), an essential LPS signaling receptor, plays a critical role in the activation of innate immunity...

Clinical studies have revealed that some patients will develop glucose tolerance dysfunction after recovering from acute pancreatitis (AP), which indicated the importance of investigating the potential therapies for restoration of islet β cell function. Cytokeratin 5 (Krt5)-positive cells are considered to function as stem or progenitor cells in the regeneration of lung and salivary gland following injury. In the present study, AP was induced by six hourly intraperitoneal injections of 100 μg/kg cerulein for 4 consecutive days in adult mice, in order to determine the role of Krt5-positive cells in pancreatic regeneration, especially in the restoration of β cell function and the underlying mechanisms...

OBJECTIVES: Inflammation in the setting of acute pancreatitis (AP) is partially driven by pathogen recognition receptors that recognize damage-associated molecular patterns. Interleukin (IL)-8 is a chemotactic factor produced by pathogen recognition receptor-expressing cells. A single-nucleotide polymorphism in IL8 promoter region (-251 A/T) has been implicated in inflammatory diseases. We examined whether this IL8 polymorphism confers susceptibility to AP. METHODS: Patients with AP (n = 357) were prospectively recruited...

BACKGROUND Aberrant regulation of nuclear factor-κB (NF-κB) and the signaling pathways that regulate its activity have been found to be involved in various pathologies, particularly cancers, as well as inflammatory and autoimmune diseases. Acute pancreatitis (AP) is a complex pathological process, depending on autodigestion caused by premature activation of zymogens. This study aimed to investigate the effect of high expression of TNIP2 gene on AP and AP-induced myocardial injury. MATERIAL AND METHODS To investigate the effect of TNIP2 on AP and AP-induced myocardial injury, we established an AP cell model and rat model...

REVIEW
Anne Walling, Robert Freelove
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)...

Clinical acute pancreatitis (AP) is marked by an early phase of systemic inflammatory response syndrome (SIRS) with multiorgan dysfunction (MODS), and a late phase characterized by sepsis with MODS. However, the mechanisms of acinar injury in human AP and the associated systemic inflammation are not clearly understood. This study, for the first time, evaluated the early interactions of bile acid induced human pancreatic acinar injury and the resulting cytokine response. We exposed freshly procured resected human pancreata to taurolithocolic acid (TLCS) and evaluated for acinar injury, cytokine release and interaction with peripheral blood mononuclear cells (PBMCs)...
