Goal: The goal of this study was to evaluate the impact of coexisting familial Mediterranean fever (FMF) on Crohn's disease (CD) patients' phenotype and disease course in an endemic region for FMF., Background: CD and FMF are inflammatory diseases characterized by recurrent abdominal pain and fever attacks. The impact of coexisting FMF on CD patients' phenotype and disease course is currently unknown., Materials and Methods: We reviewed the medical records of 210 adult CD patients who were regularly followed up at a tertiary gastroenterology clinic between November 2006 and April 2018. The patients were divided into FMF positive (CD-FMF) and FMF negative (CD-control) groups. The severity of CD was assessed by the rate of hospitalization because of CD, the need for biological therapy, and whether surgery was performed for CD., Results: Eight (3.8%) of 210 CD patients have concomitant FMF, which is 35 to 40 times higher than expected in an endemic region for FMF. Baseline demographic parameters, location/behavior of the CD, and initial therapeutic regimens were similar between the 2 groups. The prevalence of peripheral arthritis was significantly higher in CD-FMF group (37.5% vs. 10.4%, respectively, P =0.04). A significantly greater proportion of the CD-FMF patients had received biological therapy (50% vs. 11.9%; P =0.012). Steroid dependence and CD-related hospitalization rates in the CD-FMF group were relatively higher but were not statistically significant (37.5% vs. 15.3 and 62.5% vs. 41.1%)., Conclusions: Our findings indicate that the disease course of CD tends to be more severe in patients with coexisting FMF., (Copyright © 2022 Wolters Kluwer Health, Inc.

Background and Study Aims: Self expandable metal stents (SEMS) is an alternative to emergency surgery to treat malignant large bowel obstruction. It can be used either for palliation or as a bridge to curative surgery. Our study aims to review the outcomes of SEMS treatment in a tertiary center and to find predictors for the clinical outcome., Patient and Methods: We retrospectively analyzed data from SEMS insertion at Sahlgrenska University Hospital, a referral center in Western Sweden (1.7 million inhabitants), between 2014 and 2020. Data collected were age, the intent of intervention, tumor localization, complication rate, technical and clinical success, 30- and 90-days mortality as well as long-term survival for the indication bridge to surgery., Results: We identified 265 SEMS insertions (mean age 72, female 49.4%). Most SEMS were used for palliation (90.2%). The malign obstruction was most often located in the left colon (71.7%). Technical success was achieved in 259 (97.7%) cases and clinical success in 244 (92.1%) cases. Post-operative complications occurred in 11 cases (4.2%). The 30-days mortality rate was 11.7% and the 90-day was 31.7%. In our analysis the tumor site was not associated with adverse outcomes and bridge to surgery indication was a positive prognostic factor for the 90-day mortality., Conclusions: We found that SEMS is an effective and safe treatment for patients with acute obstructive colorectal cancer., (© 2022.

Solitary rectal ulcer syndrome (SRUS) is a rare disorder likely to be caused by a traumatic and ischemic mucosal injury related to latent or overt rectal prolapse. Mucosal damage can vary between erythema and up to intractable ulceration. The typical symptoms of SRUS may resemble those of inflammatory bowel disease (IBD)-related proctitis or rectal malignancy with mucus- and blood-mixed defecation with urgency and sometimes transient incontinence. The purpose of this paper is to raise awareness of this rare, quality-of-life impacting and difficult-to-treat disease and the not so well-known argon plasma coagulation (APC) treatment that can provide very good and long lasting symptom relief.

Background: Crohn's disease (CD) is characterised by chronic gastrointestinal inflammation with relapsing-remitting behaviour and often requires endoscopic and/or radiologic assessment., Objective: The objective of this study was to compare the diagnostic accuracy of intestinal ultrasound (IUS) and magnetic resonance enterography (MRE) for the assessment of disease activity in CD using a simple endoscopic score for CD as a reference standard., Patients and Methods: A prospective observational study was carried out in 71 consecutive adult patients with known CD, attending our tertiary inflammatory bowel disease clinic, between November 2014 and July 2016. Ileocolonoscopy, IUS and MRE were performed within 1 month prospectively. The simple endoscopic score-CD 0-2 was accepted as remission., Results: The sensitivity of IUS and MRE for detecting endoscopic activity was found similar with regard to bowel wall thickening and mesenteric fibrofatty proliferation (P>0.05). The overall accuracy for detecting mural lesions was similar between IUS and MRE. When mural lesions were analysed, the sensitivity of MRE in detecting the loss of wall stratification and stenosis was significantly higher than IUS (P<0.001 for both). IUS showed higher specificity for bowel wall thickening, loss of wall stratification and stenosis (P=0.009, P<0.001 and P<0.001, respectively). Sensitivity and accuracy of IUS were higher in detecting ascites in active disease (P=0.002)., Discussion: Our results showed that IUS and MRE were equally accurate in detecting endoscopic activity. IUS may be the preferred technique for the evaluation of disease activity and for the follow-up of CD.

Pantoprazole is a proton pump inhibitor that is commonly used in the treatment of peptic ulcer disease (PUD) and metabolized by cytochrome P450 (CYP) enzymes CYP2C19 and CYP3A4. Pantoprazole is a substrate for multi-drug resistance protein 1 (MDR1). Single nucleotide polymorphisms (SNPs) in CYP2C19, CYP3A4 and MDR1 affect enzyme activity or gene expression of proteins and may alter plasma pantoprazole concentrations and treatment success in PUD. In this study, we aimed to investigate the association between genetic polymorphisms in CYP2C19, CYP3A4 and MDR1 and pharmacokinetics of pantoprazole and therapeutic outcome in patients with either Helicobacter pylori-associated [H.P.(+)]-PUD or [H.P.(+)]-gastritis. The plasma pantoprazole concentrations were determined by using an HPLC method at the third hour after a 40-mg tablet of pantoprazole administration in 194 newly diagnosed patients with either [H.P.(+)]-PUD or [H.P.(+)]-gastritis. Genotyping was performed by using PCR-RFLP and DNA sequencing. Among patients appearing for follow-up examination (n = 105), the eradication rate for H. pylori was 82.8% (n = 87). The median pantoprazole plasma concentrations in poor metabolizers (PM), rapid metabolizers (RM) and ultrarapid metabolizers (URM) were 2.07, 1.69 and 1.28 μg/ml, respectively (p = 0.04). CYP3A4*1G and *22 polymorphisms did not affect plasma pantoprazole concentrations and H. pylori eradication rate. The MDR1 genetic polymorphisms did not affect plasma pantoprazole concentrations. MDR1 3435CC-2677GG-1236CC haplotype carriers had lower H. pylori eradication rate (60%) than the remaining subjects (84.9%) while the difference was not statistically significant (p = 0.07). In conclusion, while CYP2C19 genetic polymorphisms significantly affected plasma pantoprazole concentrations, polymorphisms of CYP2C19, CYP3A4 and MDR1 did not affect H. pylori eradication rates., (© 2016 Nordic Association for the Publication of BCPT (former Nordic Pharmacological Society).)

BACKGROUND The aim of this study was to investigate relationships between early atherosclerosis and inflammatory bowel disease (IBD) using laboratory, functional, and morphological markers of atherosclerosis. MATERIAL AND METHODS In the present prospective single-center study, 96 patients with IBD (58 patients with ulcerative colitis and 36 patients with Crohn's disease) and 65 healthy control subjects were included. The demographic data of each patient and control subject were recorded. The patients with IBD and healthy controls were compared in terms of the carotid intima-media thickness (CIMT), the values of flow-mediated dilatation (FMD) and nitroglycerine-mediated dilatation (NMD), and the levels of von Willebrand factor antigen (VWF-Ag), D-dimer, and lipoprotein (a). RESULTS There were no significant differences between the IBD patients and controls in terms of age, sex, BMI, systolic and diastolic BPs, serum levels of total cholesterol, low-density lipoprotein, or triglycerides. IBD patients had significantly higher levels of VWF-Ag (156.6±58.9 vs. 104.2±43.3, P<0.001) and D-dimer (337.2±710.8 vs. 175.9±110.9, P<0.001) as compared to the controls. No significant differences were determined between the 2 groups in terms of FMD and NMD values. Although statistically not significant, the CIMT values were higher in the IBD patients than in the controls (0.517±0.141 mm vs. 0.467±0.099 mm, P=0.073). In the correlation analysis, the CIMT was found to be correlated negatively with FMD and positively with high sensitive C-reactive protein, VWF-Ag, and D-dimer. CONCLUSIONS These findings suggest that VWF-Ag and D-dimer can be beneficial early atherosclerosis markers in IBD patients., Competing Interests: Conflict-of-interest statement There are no conflicts of interest.

Background: Liver biopsy is an invasive procedure that is currently still necessary for predicting underlying hepatic injury related to chronic viral hepatitis B (CVHB). To date, none of the studied non-invasive methods have been able to replace liver biopsy. An apoptotic serum marker, M30, which has been reported to indicate ongoing liver fibrosis, has been popular in recent years., Objectives: We aimed to investigate the possible role of M30 in predicting CVHB-associated hepatic injury and its severity., Methods: Forty-eight patients undergoing liver biopsy for evaluation of the severity of CVHB-related liver injury and 40 healthy controls were included in this cross-sectional study. M30 levels were determined for all CVHB patients and controls, and other laboratory parameters and demographic features were obtained from our hospital's database., Results: The mean ages of patients and controls were 39.7 and 45.7 years, respectively, and 35% of the controls and 52% of the patients were male. In contrast to lower platelet counts, transaminase and M30 levels were both higher in the patient group than in the controls. Among the investigated parameters, only transaminase increased as the fibrosis stage changed from mild to moderate; however, none of the laboratory parameters, including M30, differed as the histological activity index (HAI) score increased., Conclusions: M30 levels were higher in CVHB patients compared to healthy controls. However, M30 levels were similar in the mild and moderate stages of fibrosis, so they did not indicate the severity of underlying fibrotic or inflammatory processes in CVHB patients.

Colorectal cancer (CRC) is the third most common cause of cancer-related death in Europe. The aim of the present study was to elucidate the efficiency of the neutrophil/lymphocyte ratio (NLR), the platelet/lymphocyte ratio (PLR), and the mean platelet volume (MPV) as tools for the preoperative diagnosis of CRC and their usefulness in the follow-up of CRC. A total of 144 CRC patients, as diagnosed by colonoscopy, and 143 age-matched and sex-matched healthy participants were included in the study. Medical records were used to compare preoperative and postoperative data including hemoglobin levels, platelet counts, MPV, NLR, and PLR. NLR, PLR, and MPV were significantly higher in CRC patients preoperatively, compared with healthy participants. Receiver-operating characteristic curve analysis suggested 2.02 as the cutoff value for NLR [area under the curve (AUC): 0.921, sensitivity: 86%, specificity: 84%], 135 as the cutoff value for PLR, (AUC: 0.853, sensitivity: 70%, specificity: 90%) and 8.25 fl as the cutoff value for MPV (AUC: 0.717, sensitivity: 54%, specificity: 76%). Subgroup analysis showed that NLR, PLR, and MPV levels were also significantly higher in nonanemic CRC patients compared with the control group, which is of great theoretical and clinical value for the early detection of CRC. Surgical tumor resection resulted in a significant decrease in NLR, PLR, and MPV. Our results suggest that NLR, PLR, and MPV may be used as easily available additional biomarkers for CRC in screening the general population, as well as in postoperative follow-up.
