Concurrent Collagenous Gastritis and Collagenous Colitis: A Case Presentation and Review of the Literature.

Collagenous gastritis is a rare gastrointestinal condition, and its presence with collagenous colitis may be an exception. We describe a 31-year-old man with simultaneous collagenous gastritis and collagenous colitis. The patient initially presented with dyspepsia, anemia, and weight loss. Endoscopy assessment revealed irregular gastric atrophy with the normal colon. Gastric biopsies illustrated increased thickness and subepithelial collagen band.

Collagenous Gastritis, a Rare Cause of Dyspepsia Resistant to Treatment; A Case Report.

Collagenous gastritis is hardly ever found in children and adults. Based on the extent of collagenous changes in the bowel, various symptoms may develop including iron deficiency, anemia, and abdominal pain in most of the patients. We present a 30-year-old man with persistent abdominal pain and anemia due to collagenous gastritis.

Comparison of Glasgow-Blatchford score and full Rockall score systems to predict clinical outcomes in patients with upper gastrointestinal bleeding.

BACKGROUND: Various risk scoring systems have been recently developed to predict clinical outcomes in patients with upper gastrointestinal bleeding (UGIB). The two commonly used scoring systems include full Rockall score (RS) and the Glasgow-Blatchford score (GBS). Bleeding scores were assessed in terms of prediction of clinical outcomes in patients with UGIB. PATIENTS AND METHODS: Two hundred patients (age >18 years) with obvious symptoms of UGIB in the emergency department of Rasoul Akram Hospital were enrolled. Full RS and GBS were calculated. We followed the patients for records of rebleeding and 1-month mortality. A receiver operating characteristic curve by using areas under the curve (AUCs) was used to statistically identify the best cutoff point. RESULTS: Eighteen patients were excluded from the study due to failure to follow-up. Rebleeding and mortality rate were 9.34% (n=17) and 11.53% (n=21), respectively. Regarding 1-month mortality, full RS was better than GBS (AUC, 0.648 versus 0.582; P=0.021). GBS was more accurate in terms of detecting transfusion need (AUC, 0.757 versus 0.528; P=0.001), rebleeding rate (AUC, 0.722 versus 0.520; P=0.002), intensive care unit admission rate (AUC, 0.648 versus 0.582; P=0.021), and endoscopic intervention rate (AUC, 0.771 versus 0.650; P<0.001). CONCLUSION: We found the full RS system is better for 1-month mortality prediction while GBS system is better for prediction of other outcomes.

Association between Pattern of Gastritis and Gastroesophageal Reflux Disease in Patients with Helicobacter Pylori Infection.

BACKGROUND Reflux disease is a common gastrointestinal problem. The association between reflux disease and gastritis pattern is controversial. AIM: To determine the association between reflux disease and gastritis pattern in patients with Helicobacter pylori (H. pylori) infection. METHODS 470 patients with dyspepsia and reflux disease were enrolled in this study. The inclusion criteria were willing to participate in the study, age over 40 years, and having the criteria of ROME III for at least 3 months. Patients with history of H. pylori eradication therapy during the 3 months before the study, a history of gastric surgery, and gastric cancer were excluded. All of the participants underwent upper endoscopy and two biopsy samples were taken from antrum, body, and fundal areas. RESULTS H. pylori infection rate was 367 (78.1%) with mean age of 59.8 ± 11.4 years. Of them 131 patients (35.7%) were male. Reflux disease was detected in 273 (74.4%) patients. 216 (58.9%) and 102 (27.8%) patients had non-erosive reflux disease (NERD) and gastroesophageal reflux disease (GERD), respectively. Corpus predominant and antral predominant gastritis were seen in 72 (19.6%) and 129 (35.2%) patients, respectively. Antral gastritis was significantly associated with GERD (p<0.01). In regression analysis, antral predominant gastritis had a significant association with GERD (OR=1.92; 95%CI: 1.22- 3.12). The same result was observed in mild to moderate antral and greater curvature gastritis (OR= 1.26; 95%CI: 0.25-6.40 and OR= 3.0; 95%CI: 0.63-14.17, respectively). CONCLUSION According to these finding ,we could suggest that the pattern of gastritis could be associated with reflux disease and GERD.

Correlation of tissue transglutaminase antibody with duodenal histologic marsh grading.

BACKGROUND Recent guidelines have proposed that there is a correlation between tissue transglutaminase (tTG) antibody titers and degrees of duodenal biopsy, and that duodenal biopsy can be omitted in some patients with high levels of tTG antibody. Using data of registered patients in a gastrointestinal clinic we aimed to assess the correlation between tissue transglutaminase antibody with duodenal histologic Marsh grading in Iranian patients with celiac disease. METHODS We retrospectively reviewed hospital files of registered patients in the gastrointestinal clinic of Firoozgar Hospital, Tehran, Iran. Demographic, laboratory, and histology data of those who had tTG titer and pathology reports of duodenal biopsy based on the modified Marsh classification were extracted and used for the study. RESULTS 159 patients with available tTG titer and pathology reports were enrolled in our study. Mean ±SD of the patients was 35.6±15.2 and 100 (62.9%) of them were women. 133 out of 153 patients had villous atrophy (Marsh IIIa-IIIc). Anemia was the most common sign and bloating, abdominal pain, and diarrhea were the first three common symptoms in these patients. Mean tTG titers was significantly higher in patients graded as Marsh III (p for trend=0.003). Our results showed that tTG titer more than 9 folds higher than the kit's cut-off value was about 97.2% sensitive for Marsh II and more duodenal damage. CONCLUSION There was a correlation between tTG titers and degrees of duodenal damage in patients with celiac disease. Duodenal biopsy is not always necessary for diagnosing celiac disease and when tTG level is more than 9 folds higher than the manufacture's recommended cut-off value it can be avoided. Meanwhile small intestinal biopsy should always be considered in case of high clinical suspicion, regardless of the results of serologic testing.
