RESUMO
OBJECTIVE: To evaluate the success of artificial intelligence for early prediction of severe course, survival, and intensive care unit(ICU) requirement in patients with acute pancreatitis(AP). METHODS: Retrospectively, 1334 patients were included the study. Severity is determined according to the Revised Atlanta Classification(RAC). The success of machine learning(ML) method was evaluated by 13 simple demographic, clinical, etiologic, and laboratory features obtained on ER admission. Additionally, it was evaluated whether Balthazar-computerized tomography severity index(CTSI) at 48-h contributed to success. The dataset was split into two parts, 90% for ML(of which 70% for learning and 30% for testing) and 10% for validation and 5-fold stratified sampling has been utilized. Variable Importance was used in the selection of features during training phase of machine. The Gradient Boost Algorithm trained the machine by KNIME analytics platform. SMOTE has been applied to increase the minority classes for training. The combined effects of the measured features were examined by multivariate logistic regression analysis and reciever operating curve curves of the prediction and confidence of the target variables were obtained. RESULTS: Accuracy values for the early estimation of Atlanta severity score, ICU requirement, and survival were found as 88.20%, 98.25%, and 92.77% respectively. When Balthazar-CTSI score is used, results were found as 91.02%, 92.25%, and 98% respectively. CONCLUSIONS: The ML method we used successfully predicted the severe course, ICU requirement and survival, with promising accuracy values of over 88%. If 48-h Balthazar-CTSI is included in the calculation, the severity score and survival rates increase even more.

OBJECTIVES: To evaluate the risk factors, Atlanta severity score, Balthazar-CTSI score, and disease course in patients of varying weight with acute pancreatitis (AP). METHODS: A retrospective evaluation was made of normal weight (NW), overweight (OW), and obese (OB) patients (n:1134) with respect to demographic findings, diabetes (DM)/hypertension, smoking/alcohol use, etiologies, laboratory findings, Balthazar/Atlanta severity scores, and disease outcomes. After consistency and associations among the BMI, Balthazar, and Atlanta groups were evaluated, combined effects of risk factors on mortality, hospital and ICU stays were re-examined statistically. RESULTS: In the OB group, mean age (p < 0.001), female gender (p < 0.001), increased BUN(p < 0.027) and Hct (p = 0.039), DM(p < 0.024), and mortality (p < 0.011) were statistically significant. In the non-NW groups, the rates of complications (40.6%/38.6%), mortality (3.7%/4.9%), interventional procedures (36%/39%), and length of hospital stay (11.6%/9.8%) were increased. Obesity constituted 23.7% of severe AP(SAP) and 50% of mortality. There was no significant relationship between Atlanta and Balthazar groups and BMI, nor between Balthazar and moderate AP (MSAP) to SAP. Old age (p = 0.000), male sex (p = 0.05), obesity (p = 0.046), alcohol (p = 0.014), low Hct (p = 0.044), high CRP (p = 0.024), MSAP/SAP (p = 0.02/(p < 0.001), and any complications (p < 0.001) increased the mortality risk. Female gender (p = 0.024), smoking (p = 0.021), hypertriglyceridemia (p = 0.047), idiopathic etiology (p = 0.023), and MSAP/SAP (p < 0.001) associations increased ICU admission. Co-occurrences of higher Balthazar score (p < 0.001), MSAP/SAP (p < 0.001), all kinds of complications (p < 0.001), and recurrence (p = 0.040) increased the hospital stay (≥11 days). CONCLUSIONS: Although complications, mortality, longer hospitalization, and interventional procedures were observed more in the overweight and obese, successful prediction of Atlanta severity and Balthazar-CTSI scores based on BMI does not appear to be accurate. OB carries an increased risk for morbidity and mortality. The combined effects of risk factors increased mortality, longer hospital stays, and ICU admission.

BACKGROUND AND AIMS: This study aimed to investigate whether AI via a deep learning algorithm using endoscopic ultrasonography (EUS) images could predict the malignant potential of gastric gastrointestinal stromal tumors (GISTs). METHODS: A series of patients who underwent EUS before surgical resection for gastric GISTs were included. A total of 685 images of GISTs from 55 retrospectively included patients were used as the training data set for the AI system. Convolutional neural networks were constructed to build a deep learning model. After applying the synthetic minority oversampling technique, 70% of the generated images were used for AI training and 30% were used to test AI diagnoses. Next, validation was performed using 153 EUS images of 15 patients with GISTs. In addition, conventional EUS features of 55 patients in the training cohort were evaluated to predict the malignant potential of GISTs and mitotic index. RESULTS: The overall sensitivity, specificity, and accuracy of the AI system for predicting malignancy risk were 83%, 94%, and 82% in the training dataset, and 75%, 73%, and 66% in the validation cohort, respectively. When patients were divided into low-risk and high-risk groups, sensitivity, specificity, and accuracy increased to 99% in the training dataset and 99.7%, 99.7%, and 99.6%, respectively, in the validation cohort. No conventional EUS features were found to be associated with either malignant potential or mitotic index (P > 0.05). CONCLUSIONS: AI via a deep learning algorithm using EUS images could predict the malignant potential of gastric GISTs with high accuracy.

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.

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.

OBJECTIVES: Timely identification of patients with acute pancreatitis who are likely to have a severe disease course is critical. Based on that, many scoring systems have been developed throughout the years. Although many of them are currently in use, none of them has been proven to be ideal. In this study, we aimed to compare the discriminatory power of relatively newer risk scores with the historical ones for predicting in-hospital major adverse events, 30-day mortality and 30-day readmission rate. PATIENTS AND METHODS: Patients who had been admitted due to acute pancreatitis were retrospectively investigated. Five risk scoring systems including HAPS, Ranson, BISAP, Glasgow, and JSS were calculated using the data of the first 24h of admission. Predictive accuracy of each scoring system was calculated using the area under the receiver-operating curve method. RESULTS: Overall 690 patients were included in the study. In-hospital major adverse events were observed in 139 (20.1%) patients of whom, 19 (2.5%) died during hospitalization. 30-day all-cause mortality and 30-day readmission were observed in 22 (3.2%) and 27 (3.9%) patients respectively. Negative predictive value of each score was markedly higher compared to positive predictive values. Among all, JSS scoring system showed the highest AUC values across all end-points (0.80 for in-hospital major adverse events; 0.94 for in-hospital mortality; 0.91 for 30-day mortality). However, all five scoring systems failed to predict 30-day readmission. DISCUSSION: JSS was the best classifier among all five risk scoring systems particularly owing to its high sensitivity and negative predictive value.

OBJECTIVE: To determine the role of serum histone H3.3 and H4 in patients with chronic hepatitis B to explore any relationship between the two. METHODS: The prospective controlled clinical pilot study was conducted in the Gastroenterology Clinic of Bezmialem Vakif University, Istanbul, Turkey, from January to October 2017, and comprised biopsy-proven patients with chronic hepatitis B and healthy controls. Demographics, hepatitis B virus deoxyribonucleic acid quantity, hepatitis B e-antigen, aspartate aminotransferase, alanine transaminase, international normalized ratio, total/direct bilirubin, albumin and thrombocyte counts as well as histological activity index and fibrosis scores were noted. Data was analysed using SPSS 22. RESULTS: Of the 140 subjects, 70(50%) each were cases and controls. The overall mean age of the sample was 43.38±15.07 years (range: 18-70 years). There was positive correlation of histone H3.3 with hepatitis B virus deoxyribonucleic acid, aspartate aminotransferase, alanine transaminase and international normalized ratio levels. Histone H4 levels only correlated with hepatitis B virus deoxyribonucleic acid and international normalized ratio. Hepatitis B e-antigen positivity was present in 14(20%) of the cases. CONCLUSIONS: Histone H3.3 levels appeared to be associated with pathophysiological changes in chronic hepatitis B patients, suggesting that future treatments should target H3.3.

BACKGROUND: About half of the world population is infected with Helicobacter pylori (H. pylori), a bacterium associated with gastric cancer and considered to be a risk factor for pancreatic ductal adenocarcinoma. Whether the bacterium is associated with intraductal papillary mucinous neoplasm, believed to be a precursor of pancreatic ductal adenocarcinoma, is unknown. The aim of this study was to investigate the presence of H. pylori DNA in tissue sections of intraductal papillary mucinous neoplasm. METHODS: The presence of H. pylori DNA was tested in a retrospective controlled study of formalin-fixed, paraffin-embedded pancreatic tissues from 24 patients who underwent surgery for intraductal papillary mucinous neoplasm. Histologically normal tissues surrounding neoplasms were used as control. H. pylori DNA was evaluated after deparaffinization, DNA extraction, and purification, and results were evaluated statistically. RESULTS: Samples were collected from 13 males and 11 females with mean age 59 years (range 44-77), and consisted of 19 cases of main-duct and three cases of branched-duct intraductal papillary mucinous neoplasm. Two patients were diagnosed with pancreatic cancer and main-duct intraductal papillary mucinous neoplasm. H. pylori DNA was not detected either in intraductal papillary mucinous neoplasm tissue, or in surrounding normal tissue. CONCLUSIONS: Although H. pylori has been implicated in pancreatic ductal adenocarcinoma, it may not play a key role in the development of intraductal papillary mucinous neoplasm.

BACKGROUND/OBJECTIVES: Acute pancreatitis (AP) is a disease typically requiring in-hospital treatment. We conducted a trial to assess the feasibility of early discharge from the hospital for patients with mild non-alcoholic acute pancreatitis (NAAP). METHODS: Eighty-four patients with mild NAAP were randomized to home or hospital groups after a short hospital stay (≤24 h). AP was defined by the revised Atlanta criteria. Mild AP was defined as an Imrie score≤5 and a harmless acute pancreatitis score (HAPS)≤2 in the first 24-h of presentation. A nurse visited all patients in the home group on the 2nd, 3rd and 5th days. All patients presented for follow-up in clinic on the 7th, 14th, and 30th days. The primary outcome was the time to resolution of pain. Secondary outcomes evaluated included time to resumption of an oral diet, 30 day hospital readmission rate as well as the total costs associated with either approach to care. RESULTS: There was no difference between the groups with regards to demographics, prognostic severity scores, symptoms, and biliary findings. No patients developed organ failure, pancreatic necrosis, or died in either group. Time to the resolution of pain and resumption of solid food intake were similar. Three (3.6%) patients required readmission within 30 days, 1 from home and 2 from the hospital groups. The total cost was significantly less in home group ($139 ± 73 vs. $951 ± 715,p < 0.001). CONCLUSIONS: Mild NAAP can be safely treated at home with regular visits by a nurse under the supervision of a physician. Widespread adoption of this practice may result in large cost savings.

UNLABELLED: BACKGROUND/AIMs: H. pylori eradication has been recommended for dyspeptic patients in high prevalance regions. Triple therapies are still prescribed mostly because culture and antibiotic susceptibility tests aren't widely available in the world. Dual therapy with high-dose proton pump inhibitors reported to have higher eradication rates. Our objective was to determine eradication success and cost-effectivity of dual therapy in dyspeptic patients. METHODOLOGY: Patients were treated orally with either dual (n:74,omeprazole 20mg q.i.d and amoxicillin 1g b.i.d) or triple therapy (n:116,omeprazole 20mg b.i.d and amoxicillin 1g b.i.d and clarithromycin 500mg b.i.d) for 14 days. HpSA was requested 3 months later. The results were evaluated statistically, p values Ë0,05 were considered significant. RESULTS: Patients (n:190) were included the study((80 female,110 male, mean age: 35.6±11year(p<0.001)). Alcohol/smoking, endoscopic findings and H. pylori rates with pathological examinations were not significantly different between groups whereas there was a significant difference in HpFast tests(p<0.01). When examined with HpSA tests 3 months after the treatment, eradication rate was 81.1% in the dual therapy group versus 63.8% in the triple therapy group (p:0.011). Dual therapy was economic than triple therapy (144USDvs.107USD,p<0.001). CONCLUSIONS: Dual therapy seems more successful, cost-effective and is less risky in terms of side effects compared to standard triple therapy in patients with dyspepsia.

BACKGROUND: The SRS(TM) Endoscopic Stapling System (Medigus Ltd, Omer, Israel) is a novel method for the treatment of gastroesophageal reflux disease (GERD). The present study assessed the safety and efficacy of SRS compared with laparoscopic anti-reflux surgery (LARS). PATIENTS AND METHODS: Of 27 participants, 11 underwent SRS and 16 LARS. Symptoms were assessed using Velanovich GERD-health-related quality of life (GERD-HRQL) scores. The groups were compared in reference to operation time, improvement in GERD-HRQL scores, and postoperative course. Chi-squared and Mann-Whitney-U-tests were used for statistical analysis. RESULTS: Of 16 (59.3%) male and 11 (40.7%) female patients, mean age was 39.6 (range: 24-60) years and mean body mass index was 26.2 kg/m(2) . Both groups were statistically similar. An esophageal perforation observed in the SRS group completely recovered after over-the-scope clipping. Procedure times for SRSand LARS were 89 and 47 min, respectively (P < 0.05). Mean discharge time was longer for SRS than LARS (3 days vs 1.2 days, P < 0.05). However, this difference disappeared with the exclusion of a complicated patient with long hospitalization in the SRS group. During 6 months mean follow up, proton-pump inhibitor use was insignificantly higher in the SRS group (P > 0.05). Mean GERD-HRQL scores dropped in 87% and in 64% of patients (P > 0.05) from 29.3 to 4.1 and from 24.8 to 8.9 (P = 0.016) in LARS and SRS groups, respectively. CONCLUSION: The short-term results of SRS are promising. The forthcoming new-generation devices and increasing experience may further improve efficacy and decrease untoward effects.

BACKGROUND/AIMS: Endoscopic ultrasonography-guided gastrojejunostomy is a minimally invasive method for the management of gastric outlet obstruction. Conventionally, a lumen-apposing metal stent (LAMS) is used to create an anastomosis. However, LAMS is expensive and not widely available. In this report, we described a tubular fully covered self-expandable metallic stent (T-FCSEMS) for this purpose. METHODS: Twenty-one patients (15 men [71.4%]; median age, 66 years; range, 40-87 years) were included in this study. A total of 19 malignant (12 pancreatic, 6 gastric, and 1 metastatic rectal cancer) and 2 benign cases were observed. The proximal jejunum was punctured with a 19 G needle. The stomach and jejunum walls were dilated with a 6 F cystotome, and a 20×80 mm polytetrafluoroethylene T-FCSEMS (Hilzo) was deployed. Oral feeding was initiated after 12 to 18 hours and solid foods after 48 hours. RESULTS: The median procedure time was 33 minutes (range, 23-55 minutes). After two weeks, 19 patients tolerated oral feeding. In patients with malignancy, the median survival time was 118 days (range, 41-194 days). No serious complications or deaths occurred. All patients with malignancy tolerated oral food intake until they expired. CONCLUSION: T-FCSEMS is safe and effective. This stent should be considered as an alternative to LAMS for gastric outlet obstruction.
RESUMO
OBJECTIVE: The aim of this study was to optimize the currently used direct spectrophotometric serum prolidase enzyme activity (SPEA) assay method and compare its diagnostic accuracy with current precipitation and direct spectrophotometric assay methods, AST-to-ALT ratio, age platelet index, AST-to-platelet ratio index, cirrhosis discriminate score, Doha score, FIB-4, FibroQ, fibrosis index, Goteborg University Cirrhosis Index , King's score, and Pohl score for distinguishing Ishak F0 from F1-F3 in patients with chronic hepatitis B (CHB) infection. METHODS: Liver biopsy results from 112 patients were included in this study. RESULTS: The SPEA values were 529 (292-794) U/L, 671 (486-927) U/L, and 1077 (867-1399) U/L with the precipitation, current, and optimized direct spectrophotometric assay methods, respectively. According to multivariate logistic regression analysis optimized direct spectrophotometric SPEA was the only statistically significant parameter to predict the early stages of liver fibrosis. CONCLUSIONS: Optimized direct spectrophotometric SPEA assay method could be used to distinguish early stages of liver fibrosis in patients with CHB infection instead of the currently used spectrophotometric SPEA assay methods and other evaluated liver fibrosis indexes.

BACKGROUND AND STUDY AIMS: Gastric variceal bleeding is more severe than esophageal variceal bleeding, and is associated with higher rebleeding and mortality rates. The benefits of endoscopic ultrasound-guided coil deployment alone for treating gastric varices, compared with concomitant cyanoacrylate injection, remain unclear. Therefore, this study aimed to compare the outcomes of both modalities. PATIENTS AND METHODS: Data of patients who underwent endoscopic ultrasound-guided coil deployment with/without concomitant cyanoacrylate injection for gastric varices between 2010 and 2021 were reviewed. The rates of rebleeding, reintervention, and survival were assessed. RESULTS: Twenty-eight patients (mean age, 55.9 ± 12.9 years; 17 men) underwent endoscopic ultrasound-guided coil deployment, either alone (EUS-coil) (n = 19) or with cyanoacrylate injection (EUS-coil/CYA) (n = 9), to treat cardiofundal varices. Among the 20 patients treated for secondary prophylaxis, including 3 actively bleeding patients (11 via EUS-coil, 9 with EUS-coil/CYA), no significant differences were observed in the rates of rebleeding (1 vs. 2), reintervention (1 vs. 0) or adverse events (1 vs. 1) (all P > 0.05). The 6-month, 1-year, and 3-year overall survival rates did not differ between the treatment groups (crude survival ratio: 76.9% vs. 77.8%; survival rates: 0.923, 0.682, and 0.615 vs. 0.778 for each year; log-rank = 0.227; P = 0.633). In patients treated for primary prophylaxis (n = 8; all via EUS-coil alone), no bleeding episodes were observed after 433 days of follow-up; however, one patient required reintervention for the reappearance of varices without bleeding. CONCLUSION: EUS-coil alone was not inferior to EUS-coil/CYA combination concerning rebleeding, reintervention, or survival.

BACKGROUND: Helicobacter pylori eradication rates have tended to decrease recently, mostly due to antibiotic resistance. In the present study, our aim was to determine Hp eradication rate with the LAC plus tid metronidazole regimen and the secondary objective of this study was to identify an effective regimen for our population. METHODS: Eighty-four Hp-positive patients with non-ulcer dyspepsia were assigned into the same group. Patients were administered the classical LAC protocole (lansoprazole 30 mg bid, amoxicillin 1 g bid and claritromycin 500 mg bid for 14 days) plus metronidazole 500 mg tid for 14 days. Gastroscopy and histopathological assessment were performed before enrollment and C(14) urea breath test and stool antigen test were performed 6 weeks after treatment. RESULTS: All 84 patients completed the study. No patient left the study because of drug side effect. Total eradication rate was 75% (63/84). CONCLUSION: Although LAC plus tid metronidazole regimen achieved a much better eradication rate compared with the standard LAC regimen; this is the first study that has a relatively low success with a concomitant therapy. So in areas of high resistance like Turkey, one cannot expect a high success with any clarithromycin containing regimen and those should be avoided.

BACKGROUND: It is sometimes difficult to diagnose whether a patient has intestinal tuberculosis or Crohn's disease because both have similar clinical, pathologic, and endoscopic features. However, their therapies are completely different and a mistake in diagnosis can result with deterioration. Many laboratory methods for the diagnosis of tuberculosis require considerable time to receive a diagnostic result. We wanted to evaluate whether an immunohistochemical tuberculosis staining method can be helpful for faster differentiation of biopsy materials. METHODS: We used formalin-fixed paraffin-embedded histologically diagnosed small intestine (n=1), colon (n=7), skin (n=8), lung (n=5), lymph node (n=24) tuberculosis and Crohn's disease (n = 28) biopsy materials only with granulomas. Demographic characteristics like age and gender were also obtained. Pathology specimens were stained immunohistochemically with an antibody to VP-M660, targeting the 38-kDa antigen of Mycobacterium tuberculosis. RESULTS: In the M. tuberculosis group, 33/45 of patients have positive immunohistochemistry (IHC) staining (73% sensitivity, 93% specificity), whereas only two of 28 patients have positive staining in the Crohn's group (p<0.001). The positive staining with IHC was detected as 85.7, 75, 75, and 60% in colon, lymph node, skin, and lung granulomas, respectively, in M. tuberculosis patients. CONCLUSIONS: Immunohistochemical staining of biopsy specimens with anti-VP-M660 seems to be a simple and fast technique with 73% sensitivity and 93% specificity for establishing an earlier differentiation of M. tuberculosis from Crohn's disease.

BACKGROUND/AIMS: To determine the role of conventional video-gastroscopes for detection of early gastric cancers (EGC). METHODOLOGY: All conventional upper gastrointestinal endoscopy (UGE) reports (12000 UGE reports) and pathology reports of all UGEs, between January 2003-December 2008, were evaluated retrospectively. RESULTS: The endoscopist suspected for EGC in 163 patients. In pathological examination, EGC was confirmed only in 35 patients. In reports of another 8 patients, the endoscopist did not suspect for EGC, but in pathological examination EGC was detected. Totally EGC was defined in 43 patients [28 male, 15 female, median age; 64 years (range 29-96 years)]. Of these 43 patients, 11 were inoperable, and 32 were operated. Among those operated, finally 17 patients were diagnosed with real EGC (10% of suspected cases). The frequency of H. pylori and atrophy were 29% and 41%, respectively. Incomplete intestinal metaplasia was mostly with submucosal invasion (41%). The most common location was the corpus and the patients with mucosal EGC commonly underwent subtotal gastrectomy. The majority (82%) of the cancers were intestinal-type according to Lauren histological classification. No relation was detected between invasion-depth and lymph node metastasis and number. The sensitivity, specificity, positive and negative predictive values were found as 84%, 99%, 26% and 99% respectively. CONCLUSIONS: Conventional endoscopes have excellent specificity and negative predictive value and moderate sensitivity for early recognition of EGC. Most of early detected cancers were out of endoscopic treatment range. One-tenth of suspicious lesions were early gastric cancer, the corpus was frequent site and half of incomplete intestinal metaplasia cases were along with it.

INTRODUCTION: Mucosal healing (MH) has been a treatment target with the introduction of biological agents in Crohn's disease (CD). Histone H4 increases in chronic inflammation. AIM: Our goal was to investigate the role of serum histone H4 in predicting MH. MATERIAL AND METHODS: The study included 44 patients who applied to the endoscopy unit for ileocolonoscopic evaluation with the diagnosis of ileocecal CD and 26 healthy controls. After ileocolonoscopic evaluation, we divided the patients into 2 groups: those with and those without MH, according to the presence of endoscopic ulcer or erosion findings. Blood samples were taken from these patients to analyse serum histone H4 before the endoscopic procedure. We first compared serum histone H4 levels between CD patients and the healthy control group and then between those with and those without MH among the CD patients. Finally, we compared CRP, ESR, and serum histone H4 levels in patients with CD according to the presence of MH and symptoms. RESULTS: Serum histone H4 levels were significantly higher in ileocolonic CD patients compared to the healthy control group (p = 0.002). Also, serum histone H4 levels were significantly higher in CD patients with no MH (p = 0.028) or symptomatic patients (p = 0.033). We did not find a significant difference in C-reactive protein and erythrocyte sedimentation rate levels between CD patients in the presence of MH (p = 0.281 and p = 0.203, respectively) or symptoms (0.779 and 0.652, respectively). CONCLUSIONS: Serum histone H4 might be a useful biomarker for MH prediction in ileocolonoscopic CD patients. Validation is needed for large numbers of patients.
RESUMO
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.
RESUMO
Chronic pancreatitis (CP) is an end-stage disease with no specific therapy; therefore, an early diagnosis is of crucial importance. In this study, data from 1315 and 318 patients were analysed from acute pancreatitis (AP) and CP registries, respectively. The population from the AP registry was divided into AP (n = 983), recurrent AP (RAP, n = 270) and CP (n = 62) groups. The prevalence of CP in combination with AP, RAP2, RAP3, RAP4 and RAP5 + was 0%, 1%, 16%, 50% and 47%, respectively, suggesting that three or more episodes of AP is a strong risk factor for CP. Laboratory, imaging and clinical biomarkers highlighted that patients with RAP3 + do not show a significant difference between RAPs and CP. Data from CP registries showed 98% of patients had at least one AP and the average number of episodes was four. We mimicked the human RAPs in a mouse model and found that three or more episodes of AP cause early chronic-like morphological changes in the pancreas. We concluded that three or more attacks of AP with no morphological changes to the pancreas could be considered as early CP (ECP).The new diagnostic criteria for ECP allow the majority of CP patients to be diagnosed earlier. They can be used in hospitals with no additional costs in healthcare.
