Vascular thrombosis and systemic hypercoagulable states are known complications of pancreatitis. Higher levels of mean platelet volume (MPV) have been associated with thrombotic diseases. However, a few studies have investigated the association between acute pancreatitis and MPV. We aimed to investigate whether there is a difference of MPV and coagulation parameters in patients with active and remission in acute pancreatitis. We included 24 consecutive patients with biliary acute pancreatitis and 24 consecutive healthy age-matched and sex-matched controls. Full blood counts and other laboratory tests were collected at onset and remission. The MPV was significantly higher in patients with acute pancreatitis at admission 8.6±1.4 fl than controls 7.6±0.7 fl (P=0.005). We detected positive correlation between, aspartate aminotransferase, alanine aminotransferase, γ-glutamyltransferase, amylase, lipase, and glucose, BMI, D-dimer and MPV. However, there was negative correlation between progression, thrombocyte counts, hemoglobin and MPV. As a result higher MPV levels in acute pancreatitis may reflect hypercoagulation associated with pancreatitis.

Background and Aim: Tumor necrosis factor-like weak inducer of apoptosis (TWEAK) is a member of the tumor necrosis factor super family of structurally-related cytokines. The aim of this study was to determine the diagnostic and prognostic role of serum TWEAK concentration in patients with acute pancreatitis., Methods: Twenty four patients with acute pancreatitis and 24 consecutive healthy age- and sex-matched control subjects were included in the study. The serum concentrations of TWEAK were measured at admission and then at remission. The average time between admission and remission was 7-10 days., Results: At admission, TWEAK concentration was significantly lower in patients with acute pancreatitis compared to control subjects (p < 0.001). Serum TWEAK concentrations were elevated after the remission period, however the differences were not statistically significant. In addition, serum TWEAK concentration showed a significant, inverse correlation with amylase, lipase, CRP, AST, fibrinogen, LDH and a positive correlation with calcium, albumin and platelet count., Conclusions: Patients with acute pancreatitis have lower serum TWEAK concentration than healthy subjects. These results suggest that serum TWEAK concentration could be a potential biomarker of acute pancreatitis.

Background: Adenosine deaminase (ADA) is found in most tissues including the pancreas. Its role in inflammation and malignancy has been studied experimentally. To date, serum ADA levels in pancreatic diseases have not been studied before., Aim: To assess the levels of ADA in patients with pancreatitis and cancer of the pancreas., Methodology: Serum levels of ADA were investigated in 14 cases with acute pancreatitis (mean age 46 years; male/female 5/9), 38 with chronic pancreatitis (mean age 46 years; male/female 25/13), 21 with cancer of the pancreas (mean age 67 years; male/female 11/10), and 21 healthy controls (mean age 40 years; male/female 11/10). The ADA levels were also compared among patients with pancreatic cancer with regard to tumor size and localization and the presence of metastases. Correlation analysis between ADA and CA 19.9 was also performed., Results: Serum ADA levels were 12.66 (9.54-20.72), 12.51 (8.88-26.64), 15.36 (10.20-21.05) and 9.39 (6.58-11.84) U/l in patients with acute pancreatitis, chronic pancreatitis, pancreatic cancer, and healthy controls, respectively. Serum ADA levels were significantly higher in acute and chronic pancreatitis, and pancreatic cancer patients compared to the control group (p < 0.05). Pancreatic cancer patients had significantly higher serum ADA levels when compared with acute and chronic pancreatitis cases (p < 0.05). The serum ADA levels were comparable according to tumor size and location and the presence of metastases. There was a linear correlation between serum ADA and CA 19-9 levels (p = 0.027, r = 0.552)., Conclusions: Our data suggest that the ADA enzyme may play a role in inflammatory diseases of the pancreas. Serum ADA levels increase in pancreatic disorders especially in pancreatic cancer. It may be a serum marker for the diagnosis of pancreatic cancer., ((c) 2007 S. Karger AG, Basel and IAP.)

Autosomal-dominant polycystic kidney disease is an inherited disorder characterized by multiple cysts in kidneys and other organs. A 63-year-old man was evaluated for the etiology of recurrent pancreatitis and chronic renal failure. Multiple cysts of kidneys, liver, and pancreas and pancreas divisum was diagnosed. Pancreatitis should be included in the differential diagnosis of abdominal pain in patients with ADPKD. Pancreas divisum may be a predisposing factor for acute pancreatitis in these patients., (2006 S. Karger AG, Basel and IAP)
