Abstract Despite several studies on the link between dietary inflammatory potential and risk of several conditions, limited studies investigated the association between pro-inflammatory diet and ulcerative colitis (UC). The objective of the present study was to examine the link between food-based dietary inflammatory potential (FDIP) and odds of UC in Iranian adults. This case–control study was carried out among 109 cases and 218 randomly chosen healthy controls. UC was diagnosed and confirmed by a gastroenterologist. Patients with this condition were recruited from Iranian IBD registry. Age- and sex-matched controls were selected randomly from participants of a large cross-sectional study. Dietary data were obtained using a validated 106-item semi-quantitative food frequency questionnaire (FFQ). We calculated FDIP score using subjects’ dietary intakes of 28 pre-defined food groups. In total 67% of subjects were female. There was no significant difference in mean age between cases and controls (39.5 vs. 41.5y; p = 0.12). The median (interquartile range) of FDIP scores for cases and controls were − 1.36(3.25) and − 1.54(3.15), respectively. We found no significant association between FDIP score and UC in the crude model (OR 0.93; 95% CIs 0.53–1.63). Adjustment for several potential confounders in multivariate model did not change this association (OR 1.12; 95% CIs 0.46–2.71). We failed to observe any significant association between greater adherence to a pro-inflammatory diet and risk of UC in this study. Prospective cohort studies are needed to further assess this relationship.

Abstract Limited data are available on the association of dietary calcium intake and ulcerative colitis (UC). We aimed to investigate the relation between dietary calcium intake and UC prevalence in Iranian adults. In this population-based case–control study, diagnosed patients with UC by gastroenterologists that were registered in the Iranian inflammatory bowel disease registry were included as cases. Age and sex-matched healthy controls were selected from Study on the Epidemiology of Psychological, Alimentary Health and Nutrition (SEPAHAN) dataset. Dietary calcium intakes of participants were examined through a validated food frequency questionnaire. We included 327 middle-aged participants (109 cases and 218 controls) in the analysis; 52.1% of them were females. After adjustments for potential confounders, individuals in the third tertile of dietary calcium intake had 92% lower odds of UC, compared to those in the first tertile (OR = 0.08, 95% CI 0.02–0.27). Our analysis based on recommended dietary allowances (RDAs) intake showed that dietary Ca intake deficiency was related to increased odds of UC (OR = 9.5, 95% CI 2.98–30.91). Stratified analysis by gender revealed that these associations were significant in both genders; although the results were stronger in the male population. A Significant decreasing trend was observed for odds of UC in tertiles of dietary calcium intakes, in both males and females. Higher dietary calcium intake was associated with lower UC prevalence in Iranian adults. Inadequate dietary calcium intake was also linked to elevated odds of UC. Further prospective investigations are needed to affirm these findings.

Background/Aim: Despite the inflammatory nature of inflammatory bowel disease (IBD), limited data are available on the association of inflammatory potential of the diet and risk of ulcerative colitis (UC). We aimed to investigate the association of inflammatory potential of the diet (IPD) score and odds of UC in a case-control study.Methods: Patients with UC were enrolled from Iranian IBD registry, whose disease was confirmed by a gastroenterologist. Controls were selected randomly from the Study of the Epidemiology of Psycho Alimentary Health and Nutrition (SEPAHAN) study, a large population-based study on more than 8,000 apparently healthy individuals. Dietary intakes of 28 food items obtained from a validated dish-based food frequency questionnaire (FFQ), were used to compute IPD score.Results: This case-control study was carried out among 109 cases and 218 randomly chosen controls. Mean age of cases and controls was 39.5 ± 10.0 and 41.5 ± 11.8 y, respectively. Totally, 52% of study participants were female and 48% were male. After controlling for age, sex, and body mass index (BMI), we found that the patients with UC were more likely to be in the highest quartile of IPD score compared with controls (OR: 2.83; 95% CI: 1.41–5.69, P-trend < 0.001). This association strengthened after additional adjustment for education, smoking, medical history, and physical activity (OR: 3.48; 95% CI: 1.32–9.10, P-trend = 0.003). When we took dietary habits into account, the association was slightly attenuated (OR: 3.33; 95% CI: 1.20–9.20, P-trend = 0.005).Conclusions: We found that adherence to a pro-inflammatory diet was positively associated with greater odds of UC. Further studies are required to confirm these findings.

A few cases with esophageal bezoar have been reported in achalasia. We describe here a rare case of esophageal pharmacobezoar after ingestion of ferrous sulfate capsules in a patient with achalasia. A 29-year-old woman presented with severe dysphagia since five days earlier. She had history of achalasia since 3 years ago but had refused any treatment option. After about 3 weeks of ferrous sulfate capsules ingestion, she developed severe dysphagia and was referred to a gastroenterologist. Physical examination was unremarkable. A barium swallow revealed dilated esophagus and bird’s beak appearance. Esophagogastroduodenoscopy (EGD) showed dilated esophagus and soft black color bezoar in distal part of esophagus. The bezoar was retrieved with basket. In the next endoscopic session, achalasia balloon dilation was successfully applied. Ferrous sulfate capsules can cause pharmacobezoar in patients with achalasia. Esophageal bezoar should be considered in differential diagnosis of untreated achalasia and acute exacerbation of dysphagia.

BACKGROUND Cholecystitis is a common surgical condition. Recently, several authors have reported that DNA of bile tolerant Helicobacter spp. has been found in the human bile colonizing the biliary tract. The aim of this study was to evaluate the association between the presence of Helicobacter spp. and gallstone cholecystitis. METHODS In this case-control study, gallstones, bile, and gallbladder mucosa were collected from 25 patients without gallstone disease, 24 with acute cholecystitis, and 28 with chronic cholecystitis. The presence of Helicobacter pylori (H. pylori), Helicobacter bilis (H. bilis), Helicobacter hepaticus (H. hepaticus), and Helicobacter pullorum (H. pullorum) were investigated by polymerase chain reaction (PCR) using species-specific primers. RESULTS In this study, 77 subjects with acute and chronic cholecystitis and control groups with a mean age of 46.85 ± 14.53 years, including 58 (67.25%) women and 19 (32.75%) men were included. DNA of 10 Helicobacter spp. was detected in the bile of the patients with cholecystitis including eight H. pylori and two H. bilis. However, we could not detect H. hepaticus and H. pullorum DNA in the samples. Moreover, there was an association between H. pylori and acute cholecystitis (p = 0.048), which was found to be stronger in 31-40-year-olds group (p = 0.003). CONCLUSION We found an association between the presence of H. pylori DNA and acute gallstone cholecystitis. There is not statistically significant correlation between three enterohepatic Helicobacter spp. (H.bilis, H. hepaticus, and H. pullorum) and cholelithiasis. Given the low sample size of the patients, more studies are required to clear the clinical role of Helicobacter spp. in the gallstone disease and cholecystitis.

Background: Inflammatory bowel disease (IBD) incidence has been increased in Iran as a developing country. Surveillance is a standard method for accessing valid data about disease epidemiology to make relevant decisions for disease control, prevention, and management. We designed Isfahan IBD Surveillance Project (IISP) to make a surveillance system in this area. Methods: The project is designed in 3 phases. At the first phase, a model of step-wise approach (core, expanded core, and optional variables) for IBD surveillance was designed and implemented among IBD patients registered at a major referral gastrointestinal diseases clinic in Isfahan. Data bank program and its software were designed with suitable and multifunctional features. A total of 352 IBD cases were registered to data bank and analyzed as a pilot study of IISP. Results: A total of 352 IBD patients, including 245 ulcerative colitis (UC), 80 Crohn's disease (CD), and 27 indeterminate colitis, were registered to the data bank. Bloody stool and abdominal cramp were the most common presentation symptom among UC and CD, respectively. Extensive pancolitis was the most prevalent phenotype (40%) of UC. Over two-thirds of our IBD patients were in remission states. Biologic agents had been prescribed in about 10% of patients during disease. Primary sclerosing cholangitis was detected in about 7% and 10% of CD and UC patients, respectively. Conclusions: Valid data from a standard surveillance system are a relevant, trustworthy tool for making decision by health policy-makers. Integrated comprehensive interventional programs for disease control and management is the second phase of IISP.

Background: Musculoskeletal manifestations (MSM) of inflammatory bowel diseases (IBDs) are usually the most frequent extraintestinal manifestations. However, they are not paid enough attention during regular office visits. This cross-sectional study aimed to draw a clinical picture of MSM and their relationships with other findings in patients with IBD. Materials and Methods: Patients of our IBD cohort between March 2012 and September 2013 were consecutively evaluated. Those with current or past history of any MSM were examined by a rheumatologist. The outcome of interest was different MSMs. Distribution of IBD manifestations between the two groups of patients with (n = 20) and without (n = 253) MSM was compared. Logistic regression analysis was employed to find the relationships of demographic, clinical, and laboratory findings with MSM. Results: Two hundred and seventy-three patients were enrolled. Forty-two patients (15.4%) had extraintestinal manifestations of which twenty patients (7.5%) had at least one MSM. 7/20 patients (35%) versus 22/253 (8.7%) had other extraintestinal manifestations (P = 0.0001). 12/20 patients (57%) had arthritis (polyarthritis, 33% and oligoarthritis, 67%). The most frequent involved joints were knee and ankle observed in 8 (40%) and 7 (35%) patients, respectively. The inflammatory back pain was recorded in 5/20 patients (25%) whereas two patients (10%) had ankylosing spondylitis. In regression analysis, oral aphthous (odds ratio [OR] =8.8 [95% confidence intervals (CI), 1.7–45], P = 0.009) and other extraintestinal manifestations (OR = 5.2 [95% CI, 1.3–20], P = 0.02) were significantly related with arthritis. Conclusion: The most frequent extraintestinal manifestations in patients with IBD were MSM. Knee and ankle were the most frequent involved joints. Extraintestinal manifestations were determinant variables of arthritis.
