Acute pancreatitis in Turkey: Results of a nationwide multicenter study.

BACKGROUND: Acute pancreatitis (AP) is the most common gastrointestinal disease requiring hospitalization, with significant mortality and morbidity. We aimed to evaluate the clinical characteristics of AP and physicians' compliance with international guidelines during its management. METHODS: All patients with AP who were hospitalized at 17 tertiary centers in Turkey between April and October 2022 were evaluated in a prospective cohort study. Patients with insufficient data, COVID-19 and those aged below 18 years were excluded. The definitions were based on the 2012 revised Atlanta criteria. RESULTS: The study included 2144 patients (median age:58, 52 % female). The most common etiologies were biliary (n = 1438, 67.1 %), idiopathic (n = 259, 12 %), hypertriglyceridemia (n = 128, 6 %) and alcohol (n = 90, 4.2 %). Disease severity was mild in 1567 (73.1 %), moderate in 521 (24.3 %), and severe in 58 (2.6 %) patients. Morphology was necrotizing in 4.7 % of the patients. The overall mortality rate was 1.6 %. PASS and BISAP had the highest accuracy in predicting severe pancreatitis on admission (AUC:0.85 and 0.81, respectively). CT was performed in 61 % of the patients, with the majority (90 %) being within 72 h after admission. Prophylactic NSAIDs were not administered in 44 % of the patients with post-ERCP pancreatitis (n = 86). Antibiotics were administered to 53.7 % of the patients, and 38 % of those received them prophylactically. CONCLUSIONS: This prospective study provides an extensive report on clinical characteristics, management and outcomes of AP in real-world practice. Mortality remains high in severe cases and physicians' adherence to guidelines during management of the disease needs improvement in some aspects.

EFFICACY AND SAFETY OF GEMIFLOXACIN CONTAINING TREATMENT REGIMEN IN FIRST-LINE TREATMENT OF HELICOBACTER PYLORI.

•In eradication treatment of H. pylori gemifloxacin containing triple treatment regimen was as effective as bismuth containing quadruple treatment. •Drug adverse effects were fewer and milder in the gemifloxacin group. •Since treatment period was shorter and pills to be taken were fewer compared to quadruple treatment, patient compliance was significantly higher in the gemifloxacin group. Background - After eradication of Helicobacter pylori (H. pylori) chronic gastritis will resolve, complications due to H. pylori infection and recurrence of infection will be prevented. Objective - To determine efficacy and safety of gemifloxacin containing treatment regimen in first line treatment of H. pylori with comparison to bismuth containing quadruple therapy. Methods - This retrospective study was conducted in a tertiary care university hospital between January 2018 and January 2021 with 410 participants who were diagnosed to have H. pylori infection with biopsies obtained during upper gastrointestinal system endoscopy. Patients were distributed into two groups according to their first-line treatment regimens. First group patients were treated with amoxicillin, gemifloxacin and pantoprazole and second group patients were treated with amoxicillin, metronidazole, bismuth subcitrate and pantoprazole for seven days. Results - Intention to treat and per protocol ratios for gemifloxacin containing regimen were 90.0% and 91.2%, while quadruple treatment has these ratios as 91.7% and 93.8% respectively. Treatment success rate in both regimens were similar. But adverse effects were lower and patient compliance were better in patients who had gemifloxacin containing treatment (P<0.001). Conclusion - Gemifloxacin containing treatment regimen is as effective as bismuth containing quadruple treatment regimen for H. pylori infection and patient compliance is better in this group. Gemifloxacin containing treatment regimens may be novel and effective alternatives for eradication of H. pylori infection.

RESUMO Contexto: Após a erradicação do Helicobacter pylori (HP), a gastrite crônica será resolvida, as complicações devido à infecção por HP e a recorrência da infecção serão prevenidas. Objetivo: Determinar a eficácia e segurança do regime de tratamento contendo gemifloxacino no tratamento de primeira linha do HP, em comparação com a terapia quádrupla contendo bismuto. Métodos: Este estudo prospectivo foi conduzido em um hospital universitário de atendimento terciário entre janeiro de 2018 e janeiro de 2021, com 410 participantes diagnosticados com infecção por HP, obtidos por meio de biópsias durante a endoscopia do sistema gastrointestinal superior. Os pacientes foram divididos em dois grupos de acordo com seus regimes de tratamento de primeira linha. Os pacientes do primeiro grupo foram tratados com amoxicilina, gemifloxacino e pantoprazol, e os pacientes do segundo grupo foram tratados com amoxicilina, metronidazol, subcitrato de bismuto e pantoprazol por 7 dias. Resultados: As taxas de intenção de tratar e por protocolo para o regime contendo gemifloxacino foram de 90,0% e 91,2%, enquanto o tratamento quádruplo apresentou essas taxas como 91,7% e 93,8%, respectivamente. A taxa de sucesso do tratamento em ambos os regimes foi similar. No entanto, os efeitos adversos foram menores e a adesão dos pacientes foi melhor nos que receberam o tratamento contendo gemifloxacino (P<0,001). Conclusão: O regime de tratamento contendo gemifloxacino é tão eficaz quanto o regime de tratamento quádruplo contendo bismuto para a infecção por HP, e a adesão dos pacientes é melhor neste grupo. Os regimes de tratamento contendo gemifloxacino podem ser alternativas novas e eficazes para a erradicação da infecção por HP.

The Role of Resolvin D1 in the Differential Diagnosis of the Cholangiocarcinoma and Benign Biliary Diseases.

BACKGROUND: The discrimination of malignant biliary strictures from benign biliary diseases (BBDs) is challenging and complicated. We aimed to investigate whether Resolvin D1 (RvD1) would aid in the discrimination of cholan-giocarcinoma (CCA) from BBDs. METHODS: Thirty-one patients with CCA, 27 patients with BBD, and 30 healthy controls were enrolled in this cross-sectional study. The diagnosis of CCA was based on results obtained from abdominal USG, MRCP, abdominal CT, endosonography, and tumor markers, including CEA and CA 19-9. Histopathological evaluation was performed in the majority of patients, and the final diagnosis was based on surgery or biopsy results. RvD1, CEA, and CA 19-9 were analyzed in all patients with CCA and BBD. RESULTS: RvD1 was significantly lower in those with CCA compared to patients with BBD and healthy controls. In addition, CEA and Ca 19-9 levels were significantly higher in the CCA group than the BBD group (p < 0.001). RvD1 concentration, CA 19-9 concentration, and total bilirubin level were found to be correlated with tumor stage (r = -0.702, 0.390, and 0.569, respectively). ROC curve analysis revealed that an RvD1 concentration of < 380 ng/mL (AUC: 0.783, 95% CI: 0673 - 0.893, p < 0.001) and CA 19-9 concentration of > 94.5 U/mL (AUC: 0.94, 95% CI: 0.898 - 0.998, p < 0.001) could be used to discriminate patients with CCA from those with BBD. CONCLUSIONS: Resolvin D1 and CA 19-9 levels might be used to effectively discriminate between BBD and CCA. Moreover, both RvD1 and CA 19-9 levels are associated with the stage of CCA, indicating that they may also be used in assessing disease progression.

Celiac disease prevalence in a large series of patients with Behçet's disease.

AIM: There are common findings between Behçet's disease (BD) and celiac disease (CD) based on similar immunological pathogenesis and there is only limited data available investigating the link between these two diseases. Furthermore, documented gastrointestinal (GI) involvement with marked upper GI symptoms in BD has been rarely reported. The aim of this study was to assess the prevalence of CD and to evaluate endoscopic findings in Turkish BD patients. METHODS: A total of 210 BD patients were included in the study. All patients underwent serological testing for anti-gliadin and tissue transglutaminase antibodies. Endoscopic examinations were performed in 190 patients who accepted upper GI system endoscopy. Multiple biopsies were taken from the second portion of the duodenum in patients with positive serological assessment for CD. RESULTS: A total of 4.2% of patients with BD had positive anti-gliadin and tissue transglutaminase antibody immunoglobulin A (IgA) and IgG antibodies. The prevalence of biopsy-confirmed CD was 1.05% in Turkish BD patients. The most common endoscopic findings of patients with BD were found to be antral gastritis, duodenitis and esophagitis. CONCLUSION: Although BD and CD share many similar clinical manifestations, our results did not support a possible association between these two diseases.

Serum Toll-Like Receptor-2, Toll-Like Receptor-4 Levels in Patients with HBeAg-Negative Chronic Viral Hepatitis B.

Toll-like receptors (TLRs) may play an important role in hepatitis-B pathogenesis. However, serum TLR-2 and TLR-4 levels and their association with serum liver enzymes, hepatitis B virus (HBV) DNA, quantitative HBsAg levels, and liver biopsy findings, are unknown. A total of naive 40 HBeAg (-) chronic hepatitis B (CHB) patients and 20 healthy control subjects were recruited in this study. Liver tests, HBV DNA, serum TLR-2 and TLR-4, and quantitative HBsAg levels were evaluated among all groups. The relationship among TLR-2, TLR-4, quantitative HBsAg levels and liver tests, and liver histological findings were investigated with correlation analysis. Serum TLR-2 and TLR-4 levels in HBeAg (-) CHB patients were higher than in the control group. There was a positive correlation between serum TLR-2, TLR-4, and HBV DNA and ALT levels. We have further demonstrated that serum TLR-2 levels are correlated with AST and quantitative HBsAg levels. However, TLRs levels were not linked to the liver biopsy findings. TLR can have an important role in hepatitis B pathogenesis. Liver injury in CHB may cause elevated TLR-2 and TLR-4 levels.

The Colonic Tissue Levels of TLR2, TLR4 and Nitric Oxide in Patients with Irritable Bowel Syndrome.

Objective Irritable bowel syndrome (IBS) is a highly prevalent and debilitating functional disorder. The toll-like receptors (TLRs) are a family of pathogen-recognition receptors in the innate immune system. In the present study we aimed to investigate the TLR2, TLR4 and nitric oxide (NO) levels in patients with IBS. Methods Fifty-one IBS patients and 15 healthy controls were included in the present study. Colonic tissue levels of TLR2, TLR4 and NO were detected using an enzyme-linked immunosorbent assays (ELISA) and through biochemical methods. Results The colonic tissue levels of TLR4 and NO were significantly higher in IBS patients than in healthy controls. A subgroup analysis, which was based on the presence of diarrhea and constipation, showed that TLR2 levels were significantly higher among individuals with diarrhea-predominant IBS than among constipation-predominant IBS patients and healthy controls. The TLR4 levels were significantly higher in the diarrhea-predominant IBS patients and constipation-predominant IBS patients than in comparison healthy controls. The colonic tissue levels of NO were higher in the constipation-predominant IBS patients than in the diarrhea-predominant IBS patients and healthy controls. Conclusion In the present study we found that the colonic tissue levels of TLR and NO were elevated in IBS patients. Our results support the presence of a degree of immune dysregulation and oxidative stress in patients with IBS.

Assessment of Atrial Electromechanical Delay and Left Atrial Mechanical Functions in Patients with Ulcerative Colitis.

OBJECTIVE: Ulcerative colitis (UC) is a common inflammatory bowel disease causing systemic inflammation, which may also affect the cardiovascular system, as well as other organ systems. The aim of the current study was to evaluate left atrial (LA) mechanical functions and duration of atrial electromechanical delay (AEMD) with echocardiography in patients with UC. METHOD: A total of 91 patients, 45 with UC (Group 1) and 46 healthy individuals as control (Group 2) were included in the study. The demographic and laboratory data were recorded, and echocardiographic measurements were taken for all patients. RESULTS: In the evaluation of basal clinical and laboratory findings, no difference was detected between the two groups, except for white blood cell count (WBC) (8.26 ± 2.71 vs. 7.06 ± 1.70, P = 0.013) and high-sensitivity C-reactive protein (Hs-CRP; 3.4 ± 1.7 vs. 1.0 ± 0.8, P < 0.001). The echocardiographic assessment revealed that the diastolic parameters such as E-, E/A-, and E- waves decreased in the UC group when compared to the control group. LA mechanical functions were different between groups, except for left atrial (LA) maximal volume: LA minimum volume (22.2 ± 12.9 vs. 15.3 ± 4.7, P = 0.001), LA volume before atrial systole (29.9 ± 14.2 vs. 24.2 ± 4.9, P = 0.021), LA ejection fraction (27.4 ± 16.5 vs. 38.6 ± 10.1, P < 0.001), LA total emptying volume (17.9 ± 6.9 vs. 21.9 ± 5.9, P = 0.004), LA active emptying fraction (27.4 ± 16.5 vs. 38.6 ± 10.1, P < 0.001), LA active emptying volume (7.7 ± 3.6 vs. 9.4 ± 2.9, P = 0.013), LA passive emptying fraction (26.8 ± 10.2 vs. 33.2 ± 9.2, P = 0.002), and LA passive emptying volume (10.3 ± 4.9 vs. 12.5 ± 4.5, P = 0.029). There was a significant difference between the groups in terms of AEMD durations, except time interval from the onset of the P-wave on the surface ECG to the peak of the late diastolic wave (PA) of the tricuspid valve. The correlation analysis revealed that age and duration of disease were correlated with AEMD. CONCLUSION: The current study reported that LA volume and mechanical functions degenerated and AEMD increased in patients with UC when compared to the control group. These findings demonstrate that UC may have effects on LA electromechanical functions related to duration of disease.

Comparison of first-year results of tenofovir and entecavir treatments of nucleos(t)ide-naive chronic hepatitis B patients with hepatosteatosis.

BACKGROUND/AIM: Hepatic steatosis may influence the response to antivirals in chronic hepatitis B patients. This study aimed to compare the efficacy of entecavir and tenofovir in nucleos(t) ide-naive chronic hepatitis B patients with hepatosteatosis during 48 weeks of therapy. PATIENTS AND METHODS: We retrospectively reviewed our data for chronic hepatitis B patients. Nucleos(t) ide-naive patients with hepatosteatosis who took entecavir or tenofovir for at least 48 weeks were included. We compared entecavir and tenofovir after 48 weeks of therapy with respect to virological, biochemical, and serological responses in patients with hepatosteatosis. RESULTS: Of the 63 patients, 21 received entecavir and 42 received tenofovir. Baseline characteristics of the patients were similar except for body mass index. At the end of week 48, there was no statistically significant difference between tenofovir and entecavir treatment regarding total HBV-DNA negativity and alanine transferase normalization in patients with chronic hepatitis B and hepatosteatosis. CONCLUSIONS: Entecavir and tenofovir are similarly effective in nucleos(t)ide-naive chronic hepatitis B patients with hepatosteatosis after 48 weeks of therapy.

Intestinal fatty acid binding protein (I-FABP) as a promising test for Crohn's disease: a preliminary study.

BACKGROUND: Crohn's disease (CD) is a chronic inflammatory bowel disease that can affect any part of the gastrointestinal tract from the mouth to the anus. The clinical course presents with remissions and activations. Also, clinical findings or endoscopic activity do not always reflect the overall appropriate disease activity. This is why specific markers are always an issue of concern for the diagnosis, prediction of relapse, and monitoring of CD activity. Fatty acid binding proteins (FABPs) are intracellular proteins that are expressed abundantly in several tissues. Intestinal FABP (I-FABP) is a plasma and urine marker that indicates intestinal damage. In this preliminary study, we aimed to determine whether serum I-FABP levels are a useful marker for CD. METHODS: Seventy-four patients with CD (41 active and 33 in remission) and 37 healthy controls were included in the study. The level of serum I-FABP was determined by ELISA. Crohn's disease activity index (CDAI) and CRP were used to assess the activity of Crohn's disease and to evaluate whether I-FABP is a useful laboratory marker. RESULTS: Serum I-FABP levels of patients with active disease were observed to be statistically higher than patients in the remission and control groups (p = 0.012 and p = 0.038, respectively). No statistically significant difference was observed among patients in the remission and control groups (p = 0.145). Correlation analysis showed a positive correlation between I-FABP and CDAI (r = 0.319, p = 0.006). In addition, a positive correlation was found between CRP and I-FABP levels. CONCLUSIONS: I-FABP seems to be a useful systemic marker for CD activity.

The effect of Helicobacter pylori eradication on insulin resistance and HbA1c level in people with normal glucose levels: a prospective study.

BACKGROUND AND AIM: Helicobacter pylori (H. pylori) infection is reported to be associated with various extragastrointestinal conditions such as insulin resistance, diabetes mellitus and metabolic syndrome. These conditions are attributed to systemic inflammation, leptin or ghrelin changes due to H. pylori infection. Therefore, increasing trends in the management of H. pylori infection are ordered to maintain glycemic control. In this study, we evaluated the effect of H. pylori eradication on insulin resistance in patients with normal blood glucose concentrations. METHOD: A total of 370 patients with successful eradication were included in the study. Patients with H. pylori were given triple eradication treatment. All patients with H. pylori infection were tested for fasting glucose, fasting insulin, glicated hemoglobin (HbA1c) at baseline and 6 months after eradication treatment. Also, insulin resistance was calculated using the homeostatic model assessment of insulin resistance (HOMA-IR). Body mass index was also determined as a metabolic syndrome criteria effecting insulin resistance. RESULTS: There were significant differences in fasting glucose, fasting insulin, HbA1c, and HOMA-IR values between before treatment and after treatment(P <0.04, <0.01, <0.01, <0.01). The favorable effect of eradication was more significant in patients with BMI≥25 mg/m(2)(P<0.05). CONCLUSION: Eradication treatment has beneficial effects on insulin resistance in patients with normal glucose concentrations.

Efficacy and safety of gum chewing in adjunct to high-dose senna for bowel cleansing before colonoscopy: a single-blind randomized controlled trial.

BACKGROUND/AIMS: Inadequate bowel cleaning leads to a suboptimal colonoscopic examination. Gum chewing has been reported to have a favorable effect on postoperative bowel functions. We conducted this study to establish if gum chewing added to high-dose senna before colonoscopy promotes bowel cleaning. PATIENTS AND METHODS: In this randomized controlled study, consecutive outpatients scheduled for elective colonoscopy were randomized into two groups. Group 1 patients (n = 65) used senna solution 150 mL (300 mg senna) the night before colonoscopy. The patients also used sennoside tablet 80 mg daily for 3 days before the colonoscopy. Patients in group 2 (n = 64) were additionally advised to chew sugarless gum half an hour three-times daily after meals for these 3 days. The overall quality of colonoscopy cleaning was evaluated using the Aronchick scale by a single endoscopist who was blinded to the intervention. Difficulty of procedure, patients' tolerance, and adverse events were also evaluated. RESULTS: A total 129 patients were enrolled in the study. Superior cleaning was found in gum chewing group when compared with other group particularly in the cecum and ascending colon. Cecal intubation time was significantly shorter in the gum-chewing group (8.6 ± 5.1 and 7.1 ± 2.8 min, P = 0.03). Adverse events were more common in group 1 compared to the gum-chewing group. CONCLUSIONS: Gum chewing enhances colonoscopy bowel preparation quality. Moreover, it is a physiologically sound, safe, and an inexpensive part of the colonoscopy bowel preparation. Gum chewing could be advised in addition to high-dose senna containing bowel preparation.

The protective effect of Echinacea spp. (Echinacea angustifolia and Echinacea purpurea) in a rat colitis model induced by acetic acid.

Ulcerative colitis (UC) is a chronic disease that causes an inflammatory condition in the colon. Several cytokines, including tumor necrosis factor alpha (TNF-α), interleukin 1 beta (IL-1ß) and transforming growth factor beta (TGF-ß) are crucial components of these inflammatory pathways. New therapeutic strategies are needed for improved clinical outcomes in UC and with less adverse effects. That is why alternative therapies such as herbal remedies are increasingly being used with favorable effects in the treatment of UC. Hence, in the present study, we aimed to evaluate the protective effect of Echinacea spp in an experimental rat colitis model induced by acetic acid (AA). Acetic acid was given via a rectal route to induce acute colitis in rats. Rats were placed in four groups: control, Echinacea, Echinacea-colitis and colitis. Tumor necrosis factor alpha, IL-1ß and TGF-ß levels were measured. Histopathological comparison of the groups was also performed. The disease activity index (DAI) was significantly higher in the colitis group compared to the control, Echinacea and Echinacea-colitis groups (p<0.001). There was no significant difference between the DAI of control, Echinacea and Echinacea-colitis groups (p>0.07). The inflammatory mediators IL-1ß and TNF-α were significantly elevated in the colitis group compared to the other groups (p<0.007, <0.001 respectively). Therefore, Echinacea spp. may likely have some therapeutic favorable effects in the management of UC.

Helicobacter pylori eradication reduces microalbuminuria in type-2 diabetic patients: a prospective study.

AIM: To evaluate the effect of Helicobacter Pylori (H. pylori) eradication on microalbuminuria in type 2 diabetic patients. METHODS: Consecutive patients with dyspepsia, type 2 diabetes mellitus and microalbuminuria were recruited. Upper gastrointestinal endoscopy and rapid urease test (H. pylori fast) were performed for detecting H. pylori infection. Patients with H. pylori infection were given triple treatment. Urea breath tests were performed for all patients after eradication treatment. According to the eradication status, patients were divided into two groups, as H. pylori negative, group 1 (successful eradication group) and H. pylori positive, group 2 (unsuccessful eradication group). Twenty-four hour urine was also collected from all patients at baseline and after H. pylori eradication treatment. RESULTS: A total of 69 patients were included in the study. There were no significant differences between groups for anthropometric measurements and laboratory tests at baseline (p > 0.05). An expected significant difference was found for microlabuminuria and fasting glucose between the two groups. Microalbuminuria and fasting glucose levels were signicantly reduced in the H. pylori negative group compared with the H. pylori positive group after eradication treatment (p < 0.05). Although there was no significant decline in HbA1c levels in the H. pylori negative group, there were relatively lower HbA1c levels compared with baseline for both groups. The rate of attaining normoalbuminuria after eradication was significantly higher in group 1 compared to group 2 (p < 0.05). CONCLUSION: H. Pylori eradication was found to have a favorable effect on reducing microalbuminuria in diabetic patients.
