Activation of Polyamine Catabolism in Patients With Acute Pancreatitis
PancreatitisPolyaminesBackground: Polyamines are essential compounds in all mammalian tissues. If tissue spermidine/spermine levels, however, dramatically decrease, the cellular survival is severely endangered. Transgenic animals, where the homeostasis of cellular polyamines can be disturbed and tissue spermidine/spermine levels are decreased, acute pancreatitis evolves, indicating pancreas to be one of the most vulnerable organs for tissue polyamine catabolism. On the other hand, our own data suggests that also in other models of acute experimental pancreatitis pancreatic polyamines are changed depending on the severity of pancreatitis in such a way that the more severe pancreatitis the lower are the pancreatic polyamine levels. Minor changes were observed also in rats undergoing sham operation only. In addition of pancreatic enzymes, inflammatory mediators are also involved in the pathophysiology of the disease. CRP, IL-6, IL-8, IL-10 and Procalcitonin are useful in predicting the severity of the disease, combination of IL-6 and IL-10 at admission can predict organ failure with sensitivity of 95 %, specificity of 88 %. Hypothesis: Similar to experimental pancreatitis, blood polyamine changes are associated with acute pancreatitis also in the man. These changes are dependent on the severity of pancreatitis, but not on the etiology of pancreatitis. The changes are specific to acute pancreatitis compared with other intra-abdominal emergencies. The changes observed return to baseline during recovery. Furthermore, we assume that blood polyamine negatively correlates with IL-6, IL-8, and procalcitonin, and positively with IL-10.

Chronic PancreatitisThe goal of this study is to determine whether harvesting islets using carbon monoxide (CO)-saturated mediums can protect islet cell from death after autologous islet transplantation in patients with chronic pancreatitis.
Surgical Outcome and Differences on Histopathology in Patients With Alcoholic & Non Alcoholic Chronic...
PancreatitisChronicNumerous treatment modalities have been proposed to treat pain in alcoholic and non-alcoholic chronic pancreatitis such as analgesic medication, inhibition of gastric acid production, enzyme substitution, somatostatin analogues, nerve blockade,reduction of oxidative stress and endoscopic pancreatic duct stenting, but none of these concepts have shown long lasting benefits as surgery in clinical studies.Comparison of surgical outcome in non-alcoholic chronic pancreatitis and alcoholic chronic pancreatitis has limited data and differences on the basis of outcome in between alcoholic and non-alcoholic chronic pancreatitis are not available in literature. Although it is well known that pain is the main symptom of chronic pancreatitis, it has until now been assessed in very common and varying categories. Pain, however, is only one aspect of the large variety of sensitive facets of daily life. In addition to an improvement in pain symptoms and the preservation of pancreatic exocrine and endocrine function and other parameters, occupational rehabilitation of these mostly young patients and quality of life also should be considered in the evaluation of surgical outcome in alcoholic and non-alcoholic chronic pancreatitis. In this prospective study, we intend to find out if there are any differences in the surgical outcome on the above mentioned parameters in alcoholic and non-alcoholic chronic pancreatitis.We also plan to see if there are differences in the histopathology in these two disease settings.
Non-inferiority of Pharmacological Prevention Alone Versus Pancreatic Stents to Prevent Post-ERCP...
PancreatitisPancreatitis is the most important complication of ERCP. The severity of this condition varies from mild to severe and can lead to prolonged hospitalization, surgical interventions, and even death. Several patient-related and procedure related factors have been identified that are associated with a higher risk of post-ERCP pancreatitis. So far, several methods have been proposed to avoid pancreatitis in patients at higher risk of this complication. Several studies have shown that different drug therapies (indomethacin suppository, a sublingual nitrate tablet and the administration of intravenous Ringer's solution) each may reduce the incidence of post-ERCP pancreatitis. All these drug therapies are safe, cheap and easy to administer. Several other studies have shown that pancreatic duct stenting (placement of a plastic tube in the pancreatic duct) is an effective intervention in preventing and reducing the severity of post-ERCP pancreatitis, especially in high-risk groups. However, there are still a few drawbacks to consider with pancreatic duct stenting: there are some difficulties with insertion of a PD stent, it is associated with a need for radiological follow-up and/or repeat endoscopy for removal, higher cost and a small but important risk of complications (e.g. stent migration). Most of the clinical trials of pancreatic duct stenting were performed, before the results of trials of drug therapies were available. Moreover, no RCT (to the investigators knowledge) has compared the efficacy of pancreatic duct stenting in patients who already received a combination of drug therapies to prevent post-ERCP pancreatitis in high-risk patients. The purpose of this study is to determine the noninferiority of a combination of drug therapies in relation to pancreatic duct stenting to prevent post-ERCP pancreatitis in high-risk patients.
Short Term Pancreatic Stenting Registry
Post-ERCP Acute PancreatitisPancreatic Duct Stricture2 moreThe purpose of this study is to document clinical utility and distribution of indications for short term pancreatic stenting, and stent type preference by indication at tertiary referral centers with expertise in pancreatic endotherapy.
Somatostatin, Octreotide, Pentoxyfilline in the Prevention of Post-ERCP Pancreatitis and Molecular...
Post-ERCP Acute PancreatitisOctreotide, somatostatin and pentoxyfilline commercially available drugs that are used in various clinical situations. They are safe and known for years. Octreotide and somatostatin have been used in many studies for the prophylaxis and treatment of pancreatitis and post-ERCP pancreatitis, while pentoxyfilline has shown effect on patients with alcoholic hepatitis, obstructive vasculitis etc. The aim of the study is to evaluate the efficacy of any of those treatments for the prophylaxis and treatment of post-ERCP pancreatitis. In addition some molecular markers of acute and chronic inflammation will be measured before and after the endoscopic procedures according to the study protocol.
Endoscopic Ultrasound (EUS) Features of Chronic Pancreatitis
Chronic PancreatitisThe purpose of this study is to correlate Endoscopic Ultrasound (EUS) criteria for chronic pancreatitis with surgical pathology.
Pancreatic Cancer Screening of High-Risk Individuals in Arkansas
Pancreatic NeoplasmsPeutz-Jegher's Syndrome7 more100 subjects who have a family history of pancreatic cancer (PC), or known genetic syndromes associated with increased risk of pancreatic cancer, will be followed for five years. This data will be used to determine the pancreatic cancer and precancerous lesion detection rate in High Risk Individuals (HRIs). Subjects may agree to annual imaging and annual biomarkers or to biomarkers only.
CFTR Related Pancreatitis Study
Cystic FibrosisCFTR Gene DysfunctionThe main causes of acute recurrent pancreatitis (ARP) or chronic pancreatitis (CP) in children are defects in genes that have been associated to pancreatitis. Among these gene defects CFTR gene mutations are commonly found, 34% ARP and 23% CP . Since not every CFTR gene mutations clinically manifest, just identifying these CFTR gene mutations may not help to establish a clear role of this defect in the etiology of the individual ARP/CP. The novel beta-adrenergic sweat secretion test is a very sensitive test to detect small abnormalities in CFTR function in form of a linear gene-function relation. By identifying even mild CFTR defects, in future will help in finding the role of CFTR modulators and providing treatment to these patients.
