In developed countries, diseases of the gallbladder and the biliary tract count as some of the most frequent gastrointestinal disorders. The inflammation of the gallbladder/biliary tree is a potentially severe, even lethal condition that requires rapid diagnosis and early multidisciplinary approach to be treated. Although the frequency of these diseases is high, the treatment is not unified in Hungary yet. The aim of the evidence-based recommendation is to clarify the diagnostic criteria and severity grading of these diseases and to highlight the indications and rules of proper application of the numerous available therapeutic interventions. The recent guideline is based on the consensus of the Board members of the Endoscopic Section of the Hungarian Gastroenterology Society in contribution with renown experts of surgery, infectology as well as interventional radiology and it counts as a clear and easy applicable guide during the all-day healthcare practice. Our guidelines are based on Tokyo guidelines established on the basis of the consensus reached in the International Consensus Meeting held in Tokyo which were revised in 2013 (TG13) and in 2018 (TG18).

Recurrent acute pancreatitis prevention by the elimination of alcohol and cigarette smoking (REAPPEAR): protocol of a randomised controlled trial and a cohort study.

BACKGROUND/OBJECTIVES: Acute recurrent pancreatitis (ARP) due to alcohol and/or tobacco abuse is a preventable disease which lowers quality of life and can lead to chronic pancreatitis. The REAPPEAR study aims to investigate whether a combined patient education and cessation programme for smoking and alcohol prevents ARP. METHODS AND ANALYSIS: The REAPPEAR study consists of an international multicentre randomised controlled trial (REAPPEAR-T) testing the efficacy of a cessation programme on alcohol and smoking and a prospective cohort study (REAPPEAR-C) assessing the effects of change in alcohol consumption and smoking (irrespective of intervention). Daily smoker patients hospitalised with alcohol-induced acute pancreatitis (AP) will be enrolled. All patients will receive a standard intervention priorly to encourage alcohol and smoking cessation. Participants will be subjected to laboratory testing, measurement of blood pressure and body mass index and will provide blood, hair and urine samples for later biomarker analysis. Addiction, motivation to change, socioeconomic status and quality of life will be evaluated with questionnaires. In the trial, patients will be randomised either to the cessation programme with 3-monthly visits or to the control group with annual visits. Participants of the cessation programme will receive a brief intervention at every visit with direct feedback on their alcohol consumption based on laboratory results. The primary endpoint will be the composite of 2-year all-cause recurrence rate of AP and/or 2-year all-cause mortality. The cost-effectiveness of the cessation programme will be evaluated. An estimated 182 participants will be enrolled per group to the REAPPEAR-T with further enrolment to the cohort. ETHICS AND DISSEMINATION: The study was approved by the Scientific and Research Ethics Committee of the Hungarian Medical Research Council (40394-10/2020/EÜIG), all local ethical approvals are in place. Results will be disseminated at conferences and in peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT04647097.

Initial Renal Function (eGFR) Is a Prognostic Marker of Severe Acute Pancreatitis: A Cohort-Analysis of 1,224 Prospectively Collected Cases.

Background: Acute pancreatitis (AP) is a life-threatening disease. We aimed to explore the prognostic relevance of renal function based on estimated glomerular filtration rate (eGFR). Methods: A prospective registry of AP patients was established by the Hungarian Pancreatic Study Group. Data of 1,224 consecutive patients were collected between 2012 and 2017. Patients were divided into 3 groups according to their eGFR measured within 24 h of hospitalization: normal renal function: >90 mL/min, mild to moderate renal functional impairment: 30-90 mL/min and severe renal dysfunction: <30 mL/min. Associations of eGFR with outcome (survival, length of hospitalization, AP severity, blood glucose), inflammatory markers (erythrocyte sedimentation rate, white blood cell count), anemia and organ failure (heart, kidney, liver) were analyzed. Results: Death, longer hospitalization and severe AP, but not the cause of AP, were significantly associated with lower eGFR. The inflammatory markers (CRP, WBC count) but not anemia (Hb, Htk) were closely associated with severe renal dysfunction. Renal function was associated with heart and renal failure but not with other complications of AP such as respiratory failure, local pancreatic complications, diabetes or peptic ulcer. eGFR was not associated with liver damage (ALAT, γ-GT) or liver function (serum bilirubin) although biliary complications, alcohol and metabolic syndrome were the most common etiologies of AP. Conclusions: Our study suggests a useful prognostic value of initial eGFR in AP patients. Even mild eGFR reduction predicted mortality, severity of AP and the length of hospitalization. Thus, precise evaluation of renal function should be considered for assessing AP severity and outcome.

Glucose levels show independent and dose-dependent association with worsening acute pancreatitis outcomes: Post-hoc analysis of a prospective, international cohort of 2250 acute pancreatitis cases.

BACKGROUND: Metabolic risk factors, such as obesity, hypertension, and hyperlipidemia are independent risk factors for the development of various complications in acute pancreatitis (AP). Hypertriglyceridemia dose-dependently elicits pancreatotoxicity and worsens the outcomes of AP. The role of hyperglycemia, as a toxic metabolic factor in the clinical course of AP, has not been examined yet. METHODS: We analyzed a prospective, international cohort of 2250 AP patients, examining associations between (1) glycosylated hemoglobin (HbA1c), (2) on-admission glucose, (3) peak in-hospital glucose and clinically important outcomes (mortality, severity, complications, length of hospitalization (LOH), maximal C-reactive protein (CRP)). We conducted a binary logistic regression accounting for age, gender, etiology, diabetes, and our examined variables. Receiver Operating Characteristic Curve (ROC) was applied to detect the diagnostic accuracy of the three variables. RESULTS: Both on-admission and peak serum glucose are independently associated with AP severity and mortality, accounting for age, gender, known diabetes and AP etiology. They show a dose-dependent association with severity (p < 0.001 in both), mortality (p < 0.001), LOH (p < 0.001), maximal CRP (p < 0.001), systemic (p < 0.001) and local complications (p < 0.001). Patients with peak glucose >7 mmol/l had a 15 times higher odds for severe AP and a five times higher odds for mortality. We found a trend of increasing HbA1c with increasing LOH (p < 0.001), severity and local complications. CONCLUSIONS: On-admission and peak in-hospital glucose are independently and dose-dependently associated with increasing AP severity and mortality. In-hospital laboratory control of glucose and adequate treatment of hyperglycemia are crucial in the management of AP.

Következtetés: A középsúlyos/súlyos pancreatitises esetek aránya magasabb volt a nem biliaris pancreatitises csoportban. Biliaris pancreatitis esetén javasolt index-cholecystectomia végzése. Orv Hetil. 2021; 162(11): 413-418. INTRODUCTION: Acute pancreatitis is the leading cause of hospitalization among gastrointestinal diseases. The early readmission rate is a quality marker and the strongest prognostical factor of 1-year mortality of acute pancreatitis. OBJECTIVE: To investigate the rate and cause of early readmission among patients treated with acute pancreatitis at our clinic. METHODS: Our retrospective study was conducted among patients (>18 years) treated with acute pancreatitis between January 2010 and December 2018 at our clinic, by whom unplanned readmission happened <30 days from emission. Personal data were collected from the Hungarian Pancreas Registry. Data of biliary and non-biliary acute pancreatitis cases were compared concerning epidemiological data, cause of readmission, mean time elapsed until readmission, its duration and outcome. RESULTS: 647 patients were diagnosed with acute pancreatitis. Of them, 28 patients had early readmission. The most common causes were 1) local pancreatic complications, 2) biliary and 3) recurrence of acute pancreatitis. By investigating the biliary and non-biliary pancreatitis cases separately, the cause of readmission was biliary in 65.5% and 15%, respectively. The number of moderately severe pancreatitis cases was significantly higher in the non-biliary group. CONCLUSION: The proportion of moderate/severe diseases was higher in the non-biliary pancreatitis group. In the case of biliary pancreatitis, it is suggested to perform index cholecystectomy.

Acid suppression therapy, gastrointestinal bleeding and infection in acute pancreatitis - An international cohort study.

BACKGROUND: Acid suppressing drugs (ASD) are generally used in acute pancreatitis (AP); however, large cohorts are not available to understand their efficiency and safety. Therefore, our aims were to evaluate the association between the administration of ASDs, the outcome of AP, the frequency of gastrointestinal (GI) bleeding and GI infection in patients with AP. METHODS: We initiated an international survey and performed retrospective data analysis on AP patients hospitalized between January 2013 and December 2018. RESULTS: Data of 17,422 adult patients with AP were collected from 59 centers of 23 countries. We found that 23.3% of patients received ASDs before and 86.6% during the course of AP. ASDs were prescribed to 57.6% of patients at discharge. ASD administration was associated with more severe AP and higher mortality. GI bleeding was reported in 4.7% of patients, and it was associated with pancreatitis severity, mortality and ASD therapy. Stool culture test was performed in 6.3% of the patients with 28.4% positive results. Clostridium difficile was the cause of GI infection in 60.5% of cases. Among the patients with GI infections, 28.9% received ASDs, whereas 24.1% were without any acid suppression treatment. GI infection was associated with more severe pancreatitis and higher mortality. CONCLUSIONS: Although ASD therapy is widely used, it is unlikely to have beneficial effects either on the outcome of AP or on the prevention of GI bleeding during AP. Therefore, ASD therapy should be substantially decreased in the therapeutic management of AP.

Development of disturbance of consciousness is associated with increased severity in acute pancreatitis.

BACKGROUND: Disturbance of consciousness (DOC) may develop in acute pancreatitis (AP). In clinical practice, it is known that DOC may worsen the patient's condition, but we have no exact data on how DOC affects the outcome of AP. METHODS: From the Hungarian Pancreatic Study Groups' AP registry, 1220 prospectively collected cases were analyzed, which contained exact data on DOC, included patients with confusion, delirium, convulsion, and alcohol withdrawal, answering a post hoc defined research question. Patients were separated to Non-DOC and DOC, whereas DOC was further divided into non-alcohol related DOC (Non-ALC DOC) and ALC DOC groups. For statistical analysis, independent sample t-test, Mann-Whitney, Chi-squared, or Fisher exact test were used. RESULTS: From the 1220 patients, 47 (3.9%) developed DOC, 23 (48.9%) cases were ALC DOC vs. 24 (51.1%) Non-ALC DOC. Analysis between the DOC and Non-DOC groups showed a higher incidence of severe AP (19.2% vs. 5.3%, p < 0.001), higher mortality (14.9% vs. 1.7%, p < 0.001), and a longer length of hospitalization (LOH) (Me = 11; IQR: 8-17 days vs. Me = 9; IQR: 6-13 days, p = 0.049) respectively. Patients with ALC DOC developed more frequently moderate AP vs. Non-ALC DOC (43.5% vs. 12.5%), while the incidence of severe AP was higher in Non-ALC vs. ALC DOC group (33.3% vs. 4.4%) (p < 0.001). LOH showed a tendency to be longer in Non-ALC DOC compared to ALC DOC, respectively (Me:13; IQR:7-20 days vs. Me:9.5; IQR:8-15.5 days, p = 0.119). CONCLUSION: DOC during AP is associated with a higher rate of moderate and severe AP and increases the risk of mortality.

Hypertriglyceridemia-induced acute pancreatitis: A prospective, multicenter, international cohort analysis of 716 acute pancreatitis cases.

BACKGROUND: Hypertriglyceridemia is the third most common cause of acute pancreatitis (AP). It has been shown that hypertriglyceridemia aggravates the severity and related complications of AP; however, detailed analyses of large cohorts are contradictory. Our aim was to investigate the dose-dependent effect of hypertriglyceridemia on AP. METHODS: AP patients over 18 years old who underwent triglyceride measurement within the initial three days were included into our cohort analysis from a prospective international, multicenter AP registry operated by the Hungarian Pancreatic Study Group. Data on 716 AP cases were analyzed. Six groups were created based on the highest triglyceride level (<1.7 mmol/l, 1.7-2.19 mmol/l, 2.2-5.59 mmol/l, 5.6-11.29 mmol/l, 11.3-22.59 mmol/l, ≥22.6 mmol/l). RESULTS: Hypertriglyceridemia (≥1.7 mmol/l) presented in 30.6% of the patients and was significantly and dose-dependently associated with younger age and male gender. In 7.7% of AP cases, hypertriglyceridemia was considered as a causative etiological factor (≥11.3 mmol/l); however, 43.6% of these cases were associated with other etiologies (alcohol and biliary). Hypertriglyceridemia was significantly and dose-dependently related to obesity and diabetes. The rates of local complications and organ failure and maximum CRP level were significantly and dose-dependently raised by hypertriglyceridemia. Triglyceride above 11.3 mmol/l was linked to a significantly higher incidence of moderately severe AP and longer hospital stay, whereas triglyceride over 22.6 mmol/l was significantly associated with severe AP as well. CONCLUSION: Hypertriglyceridemia dose-dependently aggravates the severity and related complications of AP. Diagnostic workup for hypertriglyceridemia requires better awareness regardless of the etiology of AP.

New Onset of DiabetEs in aSsociation with pancreatic ductal adenocarcinoma (NODES Trial): protocol of a prospective, multicentre observational trial.

INTRODUCTION: Pancreatic ductal adenocarcinoma (PDAC) has a dismal prognosis with an overall 5-year survival of approximately 8%. The success in reducing the mortality rate of PDAC is related to the discovery of new therapeutic agents, and to a significant extent to the development of early detection and prevention programmes. Patients with new-onset diabetes mellitus (DM) represent a high-risk group for PDAC as they have an eightfold higher risk of PDAC than the general population. The proposed screening programme may allow the detection of PDAC in the early, operable stage. Diagnosing more patients in the curable stage might decrease the morbidity and mortality rates of PDAC and additionally reduce the burden of the healthcare. METHODS AND ANALYSIS: This is a prospective, multicentre observational cohort study. Patients ≥60 years old diagnosed with new-onset (≤6 months) diabetes will be included. Exclusion criteria are (1) Continuous alcohol abuse; (2) Chronic pancreatitis; (3) Previous pancreas operation/pancreatectomy; (4) Pregnancy; (5) Present malignant disease and (6) Type 1 DM. Follow-up visits are scheduled every 6 months for up to 36 months. Data collection is based on questionnaires. Clinical symptoms, body weight and fasting blood will be collected at each, carbohydrate antigen 19-9 and blood to biobank at every second visit. The blood samples will be processed to plasma and analysed with mass spectrometry (MS)-based metabolomics. The metabolomic data will be used for biomarker validation for early detection of PDAC in the high-risk group patients with new-onset diabetes. Patients with worrisome features will undergo MRI or endoscopic ultrasound investigation, and surgical referral depending on the radiological findings. One of the secondary end points is the incidence of PDAC in patients with newly diagnosed DM. ETHICS AND DISSEMINATION: The study has been approved by the Scientific and Research Ethics Committee of the Hungarian Medical Research Council (41085-6/2019). We plan to disseminate the results to several members of the healthcare system includining medical doctors, dietitians, nurses, patients and so on. We plan to publish the results in a peer-reviewed high-quality journal for professionals. In addition, we also plan to publish it for lay readers in order to maximalise the dissemination and benefits of this trial. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov NCT04164602.

Multiple Hits in Acute Pancreatitis: Components of Metabolic Syndrome Synergize Each Other's Deteriorating Effects.

INTRODUCTION: The incidence of acute pancreatitis (AP) and the prevalence of metabolic syndrome (MetS) are growing worldwide. Several studies have confirmed that obesity (OB), hyperlipidemia (HL), or diabetes mellitus (DM) can increase severity, mortality, and complications in AP. However, there is no comprehensive information on the independent or joint effect of MetS components on the outcome of AP. Our aims were (1) to understand whether the components of MetS have an independent effect on the outcome of AP and (2) to examine the joint effect of their combinations. METHODS: From 2012 to 2017, 1435 AP cases from 28 centers were included in the prospective AP Registry. Patient groups were formed retrospectively based on the presence of OB, HL, DM, and hypertension (HT). The primary endpoints were mortality, severity, complications of AP, and length of hospital stay. Odds ratio (OR) with 95% confidence intervals (CIs) were calculated. RESULTS: 1257 patients (55.7 ± 17.0 years) were included in the analysis. The presence of OB was an independent predictive factor for renal failure [OR: 2.98 (CI: 1.33-6.66)] and obese patients spent a longer time in hospital compared to non-obese patients (12.1 vs. 10.4 days, p = 0.008). HT increased the risk of severe AP [OR: 3.41 (CI: 1.39-8.37)], renal failure [OR: 7.46 (CI: 1.61-34.49)], and the length of hospitalization (11.8 vs. 10.5 days, p = 0.020). HL increased the risk of local complications [OR: 1.51 (CI: 1.10-2.07)], renal failure [OR: 6.4 (CI: 1.93-21.17)], and the incidence of newly diagnosed DM [OR: 2.55 (CI: 1.26-5.19)]. No relation was found between the presence of DM and the outcome of AP. 906 cases (mean age ± SD: 56.9 ± 16.7 years) had data on all four components of MetS available. The presence of two, three, or four MetS factors increased the incidence of an unfavorable outcome compared to patients with no MetS factors. CONCLUSION: OB, HT, and HL are independent risk factors for a number of complications. HT is an independent risk factor for severity as well. Components of MetS strongly synergize each other's detrimental effect. It is important to search for and follow up on the components of MetS in AP.

A Multicenter, International Cohort Analysis of 1435 Cases to Support Clinical Trial Design in Acute Pancreatitis.

BACKGROUND: C-reactive protein level (CRP) and white blood cell count (WBC) have been variably used in clinical trials on acute pancreatitis (AP). We assessed their potential role. METHODS: First, we investigated studies which have used CRP or WBC, to describe their current role in trials on AP. Second, we extracted the data of 1435 episodes of AP from our registry. CRP and WBC on admission, within 24 h from the onset of pain and their highest values were analyzed. Descriptive statistical tools as Kruskal-Wallis, Mann-Whitney U, Levene's F tests, Receiver Operating Characteristic (ROC) curve analysis and AUC (Area Under the Curve) with 95% confidence interval (CI) were performed. RESULTS: Our literature review showed extreme variability of CRP used as an inclusion criterion or as a primary outcome or both in past and current trials on AP. In our cohort, CRP levels on admission poorly predicted mortality and severe cases of AP; AUC: 0.669 (CI:0.569-0.770); AUC:0.681 (CI: 0.601-0.761), respectively. CRP levels measured within 24 h from the onset of pain failed to predict mortality or severity; AUC: 0.741 (CI:0.627-0.854); AUC:0.690 (CI:0.586-0.793), respectively. The highest CRP during hospitalization had equally poor predictive accuracy for mortality and severity AUC:0.656 (CI:0.544-0.768); AUC:0.705 (CI:0.640-0.769) respectively. CRP within 24 h from the onset of pain used as an inclusion criterion markedly increased the combined event rate of mortality and severe AP (13% for CRP > 25 mg/l and 28% for CRP > 200 mg/l). CONCLUSION: CRP within 24 h from the onset of pain as an inclusion criterion elevates event rates and reduces the number of patients required in trials on AP.

[Changes in antibiotic resistance in cholangitis. Our clinical experience]. / Az antibiotikumrezisztencia változása cholangitisben. Klinikai tapasztalataink.

Introduction: Due to the inappropriate use of antibiotics (AB), more pathogens become multiresistant. One of the most severe sources of sepsis is cholangitis. To avoid fatal outcome, an effective AB policy plays a key role. Aim: To investigate the AB resistance of bacteria causing cholangitis and the efficacy of AB treatment. Patients and method: Microbiological tests of bile samples collected during cholangitis-indicated endoscopic retrograde cholangiopancreatographies were analysed at the First Department of Medicine, University of Szeged, in 2006 and in 2016. Results: 29 and 111 patients had bile sample collection in 2006 and in 2016, respectively. Of that, 22 (75%) and 106 (95%) were positive. Mean age: 61 ± 14 vs. 71 ± 14 years, no difference between men/women ratio. In 2006, 10 cases empirical AB (ciprofloxacine with metronidazole or imipenem) were used. In 9 cases (90%), the AB was adequate based on the microbiological results. In 2016, in 88 cases empirical AB was applied (ciprofloxacine and metronidazole, ceftriaxone with metronidazole or imipenem with metronidazole). In 29 cases, the empirical AB was ineffective. The efficacy of ciprofloxacine decreased to 64% in 2016. The profile of the most frequent cholangitis-causing pathogens (Escherichia coli, Enterococcus faecalis, Klebsiella pneumoniae) was the same, but their resistency against ciprofloxacine increased. The rates of polymicrobal infections were 73% and 63%, respectively. Conclusion: The rates of positive bile samples were significantly higher in 2016. The profile of the most frequent pathogens was the same. The efficacy of the first-choice empirical AB ciprofloxacine decreased in 2016. The types of the most frequent cholangitis-causing bacteria are in line with the ones included in the Tokyo Guideline. Orv Hetil. 2019; 160(36): 1437-1442.

Antibiotic therapy in acute pancreatitis: From global overuse to evidence based recommendations.

BACKGROUND: Unwarranted administration of antibiotics in acute pancreatitis presents a global challenge. The clinical reasoning behind the misuse is poorly understood. Our aim was to investigate current clinical practices and develop recommendations that guide clinicians in prescribing antibiotic treatment in acute pancreatitis. METHODS: Four methods were used. 1) Systematic data collection was performed to summarize current evidence; 2) a retrospective questionnaire was developed to understand the current global clinical practice; 3) five years of prospectively collected data were analysed to identify the clinical parameters used by medical teams in the decision making process, and finally; 4) the UpToDate Grading of Recommendations, Assessment, Development and Evaluation (GRADE) system was applied to provide evidence based recommendations for healthcare professionals. RESULTS: The systematic literature search revealed no consensus on the start of AB therapy in patients with no bacterial culture test. Retrospective data collection on 9728 patients from 22 countries indicated a wide range (31-82%) of antibiotic use frequency in AP. Analysis of 56 variables from 962 patients showed that clinicians initiate antibiotic therapy based on increased WBC and/or elevated CRP, lipase and amylase levels. The above mentioned four laboratory parameters showed no association with infection in the early phase of acute pancreatitis. Instead, procalcitonin levels proved to be a better biomarker of early infection. Patients with suspected infection because of fever had no benefit from antibiotic therapy. CONCLUSIONS: The authors formulated four consensus statements to urge reduction of unjustified antibiotic treatment in acute pancreatitis and to use procalcitonin rather than WBC or CRP as biomarkers to guide decision-making.

Outcomes and timing of endoscopic retrograde cholangiopancreatography for acute biliary pancreatitis.

BACKGROUND: Indication of endoscopic retrograde cholangiopancreatography (ERCP) in acute biliary pancreatitis (ABP) is challenging. AIMS: In this retrospective study, we analyzed real-world data to understand the ERCP practice in ABP in Hungarian centers. METHODS: Clinical data on ABP patients (2013-2015) were extracted from our large multicentric database. Outcomes, quality indicators and the role of early timing of ERCP (<24 h from admission) were analyzed. RESULTS: There were 356 patients with ABP. ERCP was performed in 267 (75%). Performance indicators of ERCP proved to be suboptimal with a biliary cannulation rate of 84%. Successful vs unsuccessful cannulation of naïve papilla resulted in lower rates of local [22.9% vs 40.9%, (P = 0.012)] and systemic [4.9% vs 13.6%, (P = 0.042)] complications. Successful vs unsuccessful clearance resulted in lower rates of local complications [22.5% vs 40.8%, (P = 0.008)]. Successful cannulation and drainage correlated with less severe course of ABP [3.6% vs 15.9%, (P = 0.001) and 4.1% vs 12.2%, (P = 0.033)] respectively. A tendency of an increased rate of local complications was observed if ERCP was performed later [<24 h: 21.1% (35/166); between 24-48 h: 23.4% (11/47); >48h: 37.2% (16/43) (P = 0.088)]. CONCLUSION: Optimization of ERCP indication in ABP patients is critical as suboptimal ERCP practices in ABP without definitive stone detection are associated with poorer clinical outcomes.

In New-Onset Diabetes Mellitus, Metformin Reduces Fat Accumulation in the Liver, But Not in the Pancreas or Pericardium.

Background: Nonalcoholic fatty pancreas and liver disease (NAFPD and NAFLD) and pericardial adipose tissue (PAT) are often associated with type 2 diabetes mellitus (T2DM). Our aim was to evaluate the incidence rate of NAFLD and NAFPD, PAT size, and the effect of metformin treatment on NAFLD, NAFPD, and PAT in new-onset T2DM (NODM). Methods: Seventeen patients with NODM and 10 subjects used as a control group were involved in the study. Computed tomography (CT) and laboratory tests were performed before the beginning of metformin therapy and 4 months afterward. PAT and the amount of fat in the pancreas and liver were determined by X-ray attenuation during unenhanced CT examination and compared with the values for the control subjects. Results: Metabolic parameters improved significantly after metformin therapy. NAFLD was diagnosed in 64.7% of the patients with NODM and in 10% of the control subjects. The radiation absorption of the liver was significantly lower in the patients with NODM compared with the control group and significantly higher after metformin therapy compared with the baseline values. Only six patients (35.3%) had NAFLD after metformin therapy. NAFPD was diagnosed in 82.3% of the patients with NODM and in 20% of the control subjects. The radiation absorption of the pancreas was significantly lower in the patients with NODM compared with the control group but did not change significantly after treatment. PAT size was significantly larger in the patients with NODM and did not change significantly after metformin treatment. Conclusions: NAFLD, NAFPD, and increased PAT were detected in the majority of patients with NODM. Metformin therapy decreased the amount of fat in the liver in parallel with an improvement in the metabolic parameters and may, thus, be beneficial for preventing the late consequences of NAFLD.

Exocrine pancreatic insufficiency in type 1 and type 2 diabetes mellitus: do we need to treat it? A systematic review.

The exocrine and endocrine pancreata are very closely linked both anatomically and physiologically. Abdominal symptoms such as nausea, bloating, diarrhea, steatorrhea, and weight loss can often occur in diabetic patients. Impairments of the exocrine pancreatic function seem to be a frequent complication of diabetes mellitus; however, they are largely overlooked. The aim of this paper is to provide an overview of the current concepts of exocrine pancreatic insufficiency (PEI) in diabetes mellitus. The prevalence and symptoms of PEI in diabetes mellitus, the pathomechanism, and difficulties of diagnosis and therapy of PEI are summarized in this systematic review.

Analysis of Research Activity in Gastroenterology: Pancreatitis Is in Real Danger.

OBJECTIVE: Biomedical investment trends in 2015 show a huge decrease of investment in gastroenterology. Since academic research usually provides the basis for industrial research and development (R&D), our aim was to understand research trends in the field of gastroenterology over the last 50 years and identify the most endangered areas. METHODS: We searched for PubMed hits for gastrointestinal (GI) diseases for the 1965-2015 period. Overall, 1,554,325 articles were analyzed. Since pancreatology was identified as the most endangered field of research within gastroenterology, we carried out a detailed evaluation of research activity in pancreatology. RESULTS: In 1965, among the major benign GI disorders, 51.9% of the research was performed on hepatitis, 25.7% on pancreatitis, 21.7% on upper GI diseases and only 0.7% on the lower GI disorders. Half a century later, in 2015, research on hepatitis and upper GI diseases had not changed significantly; however, studies on pancreatitis had dropped to 10.7%, while work on the lower GI disorders had risen to 23.4%. With regard to the malignant disorders (including liver, gastric, colon, pancreatic and oesophageal cancer), no such large-scale changes were observed in the last 50 years. Detailed analyses revealed that besides the drop in research activity in pancreatitis, there are serious problems with the quality of the studies as well. Only 6.8% of clinical trials on pancreatitis were registered and only 5.5% of these registered trials were multicentre and multinational (more than five centres and nations), i.e., the kind that provides the highest level of impact and evidence level. CONCLUSIONS: There has been a clear drop in research activity in pancreatitis. New international networks and far more academic R&D activities should be established in order to find the first therapy specifically for acute pancreatitis.

New-onset type 2 diabetes mellitus--A high-risk group suitable for the screening of pancreatic cancer?

BACKGROUND: Type 2 diabetes mellitus is widely considered to be associated with pancreatic cancer. OBJECTIVE: To determine the incidence of pancreatic cancer in new-onset type 2 diabetic patients by measuring the serum level of CA 19-9 and performing abdominal ultrasonography (US). PATIENTS AND METHODS: Consecutive type 2 diabetic patients in whom diabetes was diagnosed within 36 months were included in this prospective study. Serum CA 19-9 measurement and US were performed in all patients. If any of two was positive, abdominal computer tomography (CT) was carried out. Endoscopic ultrasound-guided fine needle aspiration or direct surgical referral was performed on patients with CT-identified lesions. RESULTS: A total of 115 patients were enrolled. CA 19-9 was elevated in 10 patients but pancreatic cancer diagnosed in neither of them. Pancreatic cancer was revealed by morphological means in three patients without elevated CA 19-9 level. The sensitivity, specificity, positive-, negative predictive values and validity were 0%, 90.4%, 0%, 97.9% and 87.9% for CA 19-9, 66.7%, 100%, 100%, 99% and 99% for US, respectively. The value of the Standardized Incidence Ratio for pancreatic cancer in new-onset type-2 diabetic patients was 198.6 (95% CI = 6.25-46.9). CONCLUSIONS: The prevalence of pancreatic cancer in patients with new-onset type-2 diabetes is significantly higher than that in the general population and screening is beneficial for detecting PaC in this patient population. CA 19-9 and US is not reliable screening modality for pancreatic cancer screening in this population.
