This is an overview of relation between acute and chronic pancreatitis and between acute pancreatitis and pancreatic cancer. Acute pancreatitis and recurrent acute pancreatitis are an etiological factor of chronic pancreatitis. Population-based studies have calculated the risk of acute recurrent pancreatitis after the first attack of acute pancreatitis to be 20% and development of chronic pancreatitis after first attack of acute pancreatitis is 10%. An important risk factor is tobacco smoking. Acute and chronic pancreatitis are risk factors for pancreatic cancer. The risk of acute pancreatitis is related to the number of recurrences of acute pancreatitis, but not the etiology of acute pancreatitis. Acute pancreatitis, as well as chronic pancreatitis, are risk factors for pancreatic cancer. After an attack of acute pancreatitis or recurrent acute pancreatitis a patient should be regarded as a high risk.

BACKGROUND: Catheter ablation (CA) of atrial fibrillation (AF) is indicated in patients with recurrent and symptomatic AF episodes. Despite the strict inclusion/exclusion criteria, AF recurrence after CA remains high. Identification of a novel biomarker that would predict AF recurrence would help to stratify the patients. The aim of the study was to seek novel biomarkers among the plasmatic microRNAs (miRNAs, miRs). METHODS: A prospective monocentric study was conducted. A total of 49 consecutive AF patients indicated for CA were included. Blood sampling was performed prior to CA. RNA was isolated from plasma using commercial kits. In the exploration phase, small RNA sequencing was performed in ten AF patients (five with and five without AF recurrence) using Illumina instrument. In the validation phase, levels of selected miRNAs were determined using quantitative reverse transcription polymerase chain reaction (qRT-PCR) in all participants. RESULTS: Altogether, 22 miRNAs were identified as altered between the groups by next-generation sequencing (using the DESeq2 algorithm). Using qRT-PCR, levels of the five most altered miRNAs (miR-190b/206/326/505-5p/1296-5p) were verified in the whole cohort. Plasma levels of hsa-miR-206 were significantly higher in patients with early (within 6 months) AF recurrence and showed an increase of risk recurrence,2.65 times by every increase in its level by 1 unit in the binary logistic regression. CONCLUSION: We have identified a set of 22 plasmatic miRNAs that differ between the patients with and without AF recurrence after CA and confirmed hsa-miR-206 as a novel miRNA associated with early AF recurrence. Results shall be verified in a larger independent cohort.

Immunoglobulin G4-related diseases (IgG4-RD) are a group of diseases characterized by high serum levels of immunoglobulin G4 (IgG4), increased lymphocyte and plasma cell with IgG4 positivity in the parenchyma of some organs, and storiform fibrosis. The most frequently affected organ is the pancreas. This is an autoimmune form of pancreatitis, which can be divided into two types: Type 1, which is significantly more common than Type 2, is high in IgG4 in the pancreatic parenchyma and shows a fundamental difference in the noted presence of extrapancreatic disorders. In general, chronic inflammation is a risk factor in the development of carcinomas. Chronic pancreatitis is an accepted risk factor for the development of pancreatic cancer. The question is whether this also applies to autoimmune pancreatitis (AIP), which has some mediators of inflammation in common with sporadic pancreatitis, and what role the presence of IgG4 plays. The vast majority of the work on this topic consists of case reports, yet, even based on our own experience, we would like to say that there is a relationship between the autoimmune form of pancreatitis and pancreatic cancer, which usually occurs in the first two years after diagnosis of AIP. Also significant is the fact that the group of people with AIP, who is a clinical manifestation of IgG4-RD, was found to have an even higher incidence of extrapancreatic cancer than in the pancreas itself. Differentiating AIP from pancreatic cancer can sometimes be problematic since these diseases can both present as focal pancreatic lesions. IgG4 has been considered useful for AIP diagnosis, however, IgG4 levels can be slightly elevated, as in the case with pancreatic adenocarcinoma. IgG4 levels of over twice the upper limit are rare among patients with pancreatic adenocarcinoma. However, cases of simultaneous presentation of pancreatic cancer and AIP have been documented and should not be neglected. AIP is a condition where regular followup is mandatory, including from the perspective of possible cancerogenesis.

Autoimmune pancreatitis is a rare form of chronic pancreatitis. The first descriptions of the disease date back to the 1990s. Etiology is multifactorial, with the use of genetic, environmental and complex immunological mechanisms. It is classified into two subtypes. Type 1 is part of a group of diseases called IgG4-related disease. Clinically is autoimmune pancreatitis manifested by icterus and abdominal discomfort. It can rarely present as acute pancreatitis. There is also a completely asymptomatic form of the disease. The diagnosis is based on abnormalities in histology, imaging methods, serology, the involvement of other organs in relation to IgG4-related disease, and a significant positive response to corticosteroid therapy. Differential diagnosis between the focal form of autoimmune pancreatitis and pancreatic cancer can be complicated, with endosonography playing an important role. In the treatment, we use corticosteroids and other immunosuppressants including biological therapy. Patients with the asymptomatic disease should also be treated to prevent late complications and exocrine and endocrine insufficiency. In addition to drug treatment, endoscopic and/or surgical treatment may be necessary. Even after recovery, the disease can relapse. The relationship between autoimmune pancreatitis and malignancies has not been clearly confirmed. The goal of this review is to provide a comprehensive look at autoimmune pancreatitis and translate latest scientific knowledge into clinical practice.

BACKGROUND: Metabolic syndrome is a serious societal problem worldwide. In the Czech Republic more than 30% of the adult population are sufferers. The role of recurrent acute pancreatitis in the induction of chronic pancreatitis, following the socalled „mechanistic definition“ of chronic pancreatitis, has been unequivocally confirmed. However, there are a number of factors that may contribute to the development of chronic pancreatitis. The first aim of the study was to determine whether the metabolic syndrome may affect the development of chronic pancreatitis. The second question we asked ourselves was whether even one acute attack of pancreatitis could be an inductive factor in chronic pancreatitis. METHODS: Based on data obtained retrospectively from a total of 264 people diagnosed with chronic pancreatitis in 4 centers, a total of 59 people (22.3%) diagnosed within 36 months of a first attack of acute pancreatitis was obtained. Etiologies of either genetically induced pancreatitis or autoimmune pancreatitis were excluded. Diagnostics to identify the presence of metabolic syndrome were run on the 59 persons so obtained using the criteria from the socalled „harmonized“ definition of 2009 (obesity, arterial hypertension, hypertriglyceridemia, type 2 diabetes mellitus and a decreased level of HDL cholesterol). RESULTS: Comparing the findings of the individual components of metabolic syndrome in persons with chronic pancreatitis after a 1st attack of acute pancreatitis with the metabolic syndrome and in persons with chronic pancreatitis after the 1st attack of acute pancreatitis but without metabolic syndrome, a statistically significant difference in obesity was found (82.5% vs. 28.5%), hypertriglyceridemia (82.3% vs 17.8%) and arterial hypertension (70.5% vs 21.4%). The interval during which chronic pancreatitis occurred after acute pancreatitis averaged 12 months (10-14 months) in subjects with metabolic syndrome, whereas in the group without metabolic syndrome the interval was longer, 20 months (16-29 months). CONCLUSION: Our results show that even one attack of acute pancreatitis (regardless of etiology) can be an inductive factor in chronic pancreatitis. The presence of metabolic syndrome can accelerate the development of chronic pancreatitis after one has had acute pancreatitis.

INTRODUCTION: The 6-thioguanine nucleotide (6-TGN) level, may be used to estimate dose-adequacy of azathioprine (AZA) therapy. 6-TGN test is not commercially available. The aim of the study was to determine whether a blood cell changes correlate also with the dose of AZA and may serve as a predictor of the dose adequacy (for MCV > 6 fl). METHODS: Retrospective, multicentre study in subjects with IBD treated with azathioprine. Demographic data, leukocyte, platelet counts, erythrocyte (MCV) and thrombocyte (MPV) volume, azathioprine dose, inflammatory activity in the 3rd, 6th and 12th months of treatment and presence of sideropenia were recorded. RESULTS: 103 subjects analysed. To increase the MCV by 6 fl, the AZA dose above 2 mg/kg is needed (p = 0.04). The MCV increases within 165 days (95% CI, 154-181 days, p = 0.002). Sideropenia has no impact on the MCV change. Number of leukocytes and thrombocytes decreases during treatment (p < 0.001). Change in their number as well as MPV, does not correlate with MCV change and is not affected by activity of the inflammation. CONCLUSION: The MCV dynamics (> 6 fl within 6 months) is the only relevant indicator during AZA treatment. Changes in the number of leukocytes, platelets and their volume can not be used to assess the sufficiency of the AZA dose. Sideropenia has no impact on the dynamics of MCV.

UNLABELLED: The aim of this retrospective study is to evaluate our experience with diagnostic and therapeutic endoscopic retrograde cholangiopancreaticography (ERCP) in patients after choledochoduodenoanastomosis. METHODS: The study took 20 years (November 1994 - December 2014). Three patients after choledochoduodenoanastomosis who had symptoms of biliary obstruction were retrospectively evaluated. In all cases, a standard therapeutic videolateroscope was used to perform ERCP. PATIENTS AND RESULTS: We achieved ERCP in these 3 patients with choledochoduodenoanastomosis 100% cannulation success rate - 3 out of 3 patients. This was 100% success rate of diagnostic ERCP. In all of these patients, ERCP was found - both stenosis of the natural mouth of the Vater papilla, stenosis of choledochoduodenoanastomosis, and suprastenotic distal choledocholithiasis. In all patients with the above-described ERCP pathology, endoscopic treatment was initiated immediately after diagnostic ERCP, consisting of standard endoscopic papillotomy of the stenotic Vater papilla, balloon dilatation of choledochoduodenoanastomosis stenosis, and endoscopic extraction of suprastenotic distal choledocholithiasis. In total, therapeutic ERCP was completely successful in all 3 patients out of 3 (100%) who had initially started endoscopic treatment. There were no complications in our group of 3 patients. CONCLUSION: In ERCP in patients after choledochoduodenoanastomosis, we achieved 100% success of both diagnostic and therapeutic ERCP in all of our 3 patients.

The stomach resection according to Billroth I (B I) is very rarely done. The aim of this retrospective study is to evaluate our experience with diagnostic and therapeutic endoscopic retrograde cholangiopancreatography (ERCP) in patients after stomach resection according to Billroth I. In patients with a condition after stomach resection according to B I, a study of the group of 20 years (November 1994 - December 2014) took place. Three patients were evaluated retrospectively after B I stomach resection with biliary obstruction. For the ERCP was used the Olympus therapeutic videotheroscop in all cases with the standard (as in normal anatomical situation). Cannulation success in diagnostic ERCP was achieved in 3 out of 3 patients - 100% success rate of ERC diagnosis. For all these 3 patients CDL was found in the ERCP. In addition, endoscopic treatment was performed immediately after ERCP diagnosis in all 3 patients with a CDL pathologic ERCP diagnosis, the initial endoscopic papillotomy (EPT) performed in the standard procedure (as in normal anatomy). Subsequently, endoscopic extraction of all CDL from hepatocholedocus to duodenum was performed. Overall the ERCP was completely successful in all 3 of the 3 (100% of 3) patients who initially started endoscopic therapy. There were no complications in our group of 3 patients. For ERCP in patients with BI stomach resection, we had 100% success rate of diagnostic and therapeutic ERCP in all of these patients (3 CDL patients).
