interleukin-8 and Pancreatic-Diseases

The objective of the study was to observe the effects of Salvia miltiorrhiza on intercellular adhesion molecule 1 (ICAM-1) protein expression in the lungs of rats with severe acute pancreatitis (SAP) or obstructive jaundice (OJ).. A total of 288 rats were used for SAP- and OJ-associated experiments. The rats were randomly divided into sham-operated, model control, and treated group. According to the difference of time points after operation, the SAP rats of each group were subdivided into 3-, 6-, and 12-hour groups, whereas the OJ rats were divided into 7-, 14-, 21-, and 28-day groups. The contents of interleukin (IL) 6, IL-18, nitric oxide, malondialdehyde, and superoxide dismutase in serum were determined, and pathological changes and ICAM-1 protein expression in the lungs were observed.. Compared with the respective model control groups, in treated groups of SAP and OJ rats, the numbers of dead rats declined; serum superoxide dismutase content significantly increased, and serum IL-18, IL-6, and malondialdehyde contents were significantly decreased; the positive staining intensity of ICAM-1 protein in the lungs decreased significantly (P < 0.05, P < 0.01, or P < 0.001); and pathological changes in the lungs were relieved.. Salvia miltiorrhiza plays a positive role in the protection of the lungs of SAP and OJ rats.

Cytokine concentration in pancreatic juice of patients with pancreatic disease is unknown. Secretin stimulation allows endoscopic collection of pancreatic juice secreted into the duodenum. We aimed to evaluate the cytokine concentrations in pancreatic juice of patients with abdominal pain to discriminate presence from absence of pancreatic disease.. From January 2003-December 2004, consecutive patients with abdominal pain compatible with pancreatic origin were enrolled. Patients underwent upper endoscopy. Intravenous secretin (0.2 mug/kg) was given immediately before scope intubation. Pancreatic juice collected from the duodenum was immediately snap-frozen in liquid nitrogen until assays were performed. Pancreatic juice levels of interleukin-8, interleukin-6, intercellular adhesion molecule 1, and transforming growth factor-beta 1 were measured by modified enzyme-linked immunosorbent assays. The final diagnosis was made by the primary gastroenterologist on the basis of medical history; laboratory, endoscopic, and imaging studies; and clinical follow-up. Fisher exact test and Kruskal-Wallis rank sum test were used for statistical analysis.. Of 130 patients screened, 118 met the inclusion criteria. Multivariate analysis revealed that only interleukin-8 was able to discriminate between normal pancreas and chronic pancreatitis (P = .011), pancreatic cancer (P = .044), and the presence of pancreatic diseases (P = .007). Individual cytokine concentrations were not significantly different in chronic pancreatitis compared with pancreatic cancer.. Cytokine levels can be measured in pancreatic juice obtained from the duodenum without direct cannulation of the pancreatic duct. Interleukin-8 concentration in pancreatic juice can be used to discriminate between normal pancreas and patients with pancreatic disease. This is a relatively simple and noninvasive method to aid in the diagnosis of pancreatic diseases.

Exaggerated cytokines productions and development of systemic inflammatory response (SIRS) is the most common cause of postoperative complications and death after major abdominal surgery. The present study was conducted to investigate alterations in systemic production of interleukin-6 (IL-6) and interleukin-8 (IL-8) after total parenteral nutrition (TPN) in surgical patients. Plasma concentrations of IL-6 and IL-8 were measured in 22 patients (10 treated with TPN and 12 without TPN) before major surgery and on the days 1, 3, 7, 10 and 14-16 after, by ELISA test (indications for surgery: stomach, pancreatic and colon carcinoma, complications of IBD and acute pancreatitis). There were no differences between preoperative levels of IL-6 and IL-8 in the examined groups of patients. The highest (on the days 1, 3, 7, 10: 268.3 (p = 0.002), 41.9 (p = 0.03), 122.6 (p = 0.009), 29.3 (p = 0.03) pg/ml respectively) and longer lasting significantly elevated level of IL-6 was observed in the group of patients after major surgery without TPN. In the group of patients received TPN (with glutamine) there was a significantly increased but in comparison with group of patients without TPN, significantly lower level of IL-6 on days 1 and 7 (103.4 and 34.7 pg/ml respectively, p = 0.01). There was no significant change in postoperative concentration of IL-8 after major surgery in the group of patients treated with TPN. The level of IL-8 was significantly elevated (p = 0.01) in the group of patients without TPN on day 1 and 3 following surgery. The IL-8 level in the TPN group vs. group of patients without TPN was significantly lower on day 1 after surgery. After TPN concentration of cholesterol was significantly higher and CRP level significantly lower. We conclude that TPN improved immunological response to major surgical trauma by reduction of the inflammatory response.
