Nodular lymphoid hyperplasia is uncommon in adult patients. Associated diseases are common variable immunodeficiency (CVI) and lymphoid tissue malignancies. In this case report we focus on clinical presentation and differential diagnosis of diffuse nodular lymphoid hyperplasia of the gastrointestinal tract coexisting with selective immunoglobulin A(More)
AIM Acute pancreatitis (AP) is the most common and often severe complication of endoscopic retrograde cholangiopancreatography (ERCP). The early step in the pathogenesis of acute pancreatitis is probably the capillary endothelial injury mediated by oxygen-derived free radicals. N-acetylcysteine - a free radical scavenger may be potentially effective in(More)
We have recently observed an increased interest in gastro-entero-pancreatic neuroendocrine tumors (GEP NET). They are rare cancer types and therefore collaborative effort of specialists in various disciplines of medicine is necessary to work out the diagnostic and therapeutic guidelines. In this publication we present general guidelines of the Polish(More)
In recent years the use of faecal and serologic biomarkers has been evaluated in the diagnosis and management of inflammatory bowel disease (IBD). Faecal calprotectin (FC) has been proposed as a surrogate marker for intestinal inflammation; elevated concentrations in IBD patients have been confirmed in numerous studies. Already available rapid calprotectin(More)
BACKGROUND/AIMS Analysis of cystic fluid may be useful in distinguishing between benign and malignant cysts which has significant impact on their management. The aim of our study was to assess the diagnostic utility of carcinoembryonic antigen (CEA) and K-ras gene mutation in pancreatic cysts fluid. METHODS The study included 56 patients with pancreatic(More)
This paper complements the previously published Guidelines of the Working Group of the Polish Society of Gastroenterology and former National Consultant in Gastroenterology regarding the management of patients with Crohn's disease and ulcerative colitis. Attention was focused on the new pharmaceutical recently registered for inflammatory bowel disease(More)
OBJECTIVES A randomized controlled trial was conducted to clarify whether continuous regional arterial infusion (CRAI) of protease inhibitor and antibiotic could reduce mortality rate of severe acute pancreatitis (SAP). METHODS Seventy-eight patients with SAP were included in the study. Thirty-nine patients were treated with CRAI, 31 patients completed(More)
PURPOSE This study was undertaken to test the hypothesis that high concentrations of urea in gastric juice would have an influence on Helicobacter pylori infection in patients maintained on chronic hemodialysis (HD). MATERIAL AND METHODS We investigated 30 patients (17 males, 13 females; mean age 50.8 +/- 2.9 years) with end-stage renal disease (ESRD)(More)
The importance of polyamines in tissue growth and regeneration was shown. The involvement of phospholipase D (PLD) activity in pancreas recovery after acute pancreatitis (AP) was postulated. Thus, the aim of present study was to evaluate: the effect of polyamines synthesis inhibition on pancreas regeneration after AP and possible relationship between(More)
INTRODUCTION Fecal calprotectin (FC) is a well‑established biomarker of intestinal inflammation in Crohn disease (CD) and ulcerative colitis (UC). However, standard laboratory methods are time‑consuming and not always useful in clinical practice. OBJECTIVES We analyzed the efficacy of a rapid bedside FC test to detect disease flares in a hospital setting.(More)
