ABSTRACT
Background and Aims: Some studies have reported the coexistence of inflammatory bowel disease (IBD) and celiac disease (CD). However, the prevalence of anti-tissue transglutaminase antibodies (IgA and IgG) and their screening value in patients with IBD is not yet clear. This study aimed to assess the prevalence of IgA anti-tTG and its potential correlation with disease status in patients with IBD. Materials and Methods: This cross-sectional study was conducted on 110 patients with confirmed IBD diagnosis at Ghaem Hospital, Mashhad, Iran. For each patient, all demographic and clinical data including age, extra intestinal manifestations, underlying diseases, types of diseases, and surgical history were collected. IgA anti-tissue transglutaminase titers were assessed by enzyme-linked immunosorbent assay. Results: None of the patients with IBD were positive for IgA anti-tTG antibodies, with a mean titer of 3.31 ± 1.3 AU/mL. Also, the mean titers were not associated with age, gender and various disease clinical features including the disease history, underlying disease, diagnosis type, extraintestinal manifestations, and surgery history. Conclusion: No significant prevalence pattern of IgA anti-tTG antibody was observed in patients with IBD. Accordingly, serological screening for CeD is not recommended in IBD patients, unless in a relevant clinical CeD suspicion. (AU)

Nutritional deficiencies and malnutrition are considered to be related to ulcerative colitis (UC); however, the association between serum levels of micronutrients and UC is not well known. This study aimed to evaluate the serum levels of micronutrients in UC patients and investigate their association with disease activity.This cross-sectional study was conducted on UC patients visiting the Department of Gastroenterology at 3 different teaching hospitals between January 2016 and January 2017. UC activity was measured based on Truelove and Witts' severity index and guidelines for colonoscopy. A healthy gender- and age-matched group was also selected. Serum levels of zinc, copper, selenium, ceruloplasmin, albumin, and total protein were compared between the 2 groups of UC patients and healthy subjects using independent-samples t test. Also, the association between serum levels of micronutrients and UC activity was assessed by using Pearson and Spearman correlation coefficient tests. The data were analyzed by SPSS version 21, considering P ≤.05 as the statistical significance level.Overall, 112 (54 male and 58 female) individuals with the mean age of 34.6 years were studied in the 2 groups of UC patients (nâ=â56) and healthy subjects (nâ=â56). The 2 groups were homogeneous in terms of age, gender, marital status, place of residence, and educational level (Pâ>.05). The serum levels of total protein (6.41â±â1.1 vs 7.41â±â0.4âg/dL; Pâ=â.0001), albumin (4.72â±â1.1 vs 5.19â±â0.28âg/dL; Pâ=â.0001), zinc (679â±â62 vs 1055â±â156âµg/L; Pâ=â.0001), and selenium (81.85â±â6.4 vs 108.4â±â12.98âmicg/L; Pâ=â.0001) were significantly lower in the UC patients. The serum level of copper did not differ significantly between the 2 groups (Pâ=â.1).Considering the simultaneous reduction in nutritional criteria in the UC patient group, malnutrition appears to be a factor affecting micronutrient deficiency in patients with UC.

AIM: To evaluate the association between biochemical, virologic and histologic features in patients with HBeAg-negative chronic hepatitis B (CHB). BACKGROUND: Hepatitis-B e-antigen (HBeAg)-negative is common in Iran, is progressive with poor prognosis. Therefore, it seems necessary to perform a comprehensive evaluation of different spectrum of laboratory measurements accompanying histological findings. METHODS: HBeAg- negative CHB patients referring to two university hospitals during two years were enrolled. Alcohol consumption, liver mass, fatty liver and positive results of Anti HDV, Anti HCV or Anti HIV were excluded. The relationship between viral loads, liver enzymes (old and new cutoffs) and histopathological features was analyzed using descriptive and analytic statistical methods. RESULTS: A total of 150 HBeAg-negative CHB (males=110, mean age=38.44±11.34 years) were assessed. ALT had a significant relation with the logarithm of serum HBV-DNA (P<0.0001), grade and stage on liver biopsy (P<0.001, P=0.034, respectively). Serum viral load, AST and ALT were independent predictors of histological grade, age was the only independent predictor of the stage of liver fibrosis. There was a significant relationship between serum ALT and stage of liver fibrosis (P<0.0001) when new cutoff values for ALT were considered. We found that age had a significant relation with histological grade but it showed a reverse relation with ALT levels (P=0.009). CONCLUSION: In HBeAg-negative CHB, AST had a better prediction for liver necrosis and inflammation. Age could be an independent predictor for liver fibrosis. New cutoff values for ALT had superiority over conventional values to identify higher risk of liver fibrosis.
ABSTRACT
Bile duct adenoma (BDA) is a rare neoplasm of bile ducts with various clinical manifestations and imaging appearances. A few cases of BDA and their predisposing factors have been described. We report a 35-year-old woman with right upper quadrant pain who consumed oral contraceptive pills. Ultrasound study revealed three hypoechoic subcapsular liver masses; two of them were hypodense in computed tomography. Fine needle biopsy of the largest mass showed bile duct adenoma. Liver masses disappeared after discontinuing the pills over a 2-year follow-up. BDAs can manifest in imaging. Although previous studies have not reported tumor resolution over a follow-up period, we suggest paying more attention to predisposing factors in order to give an opportunity for tumor resolution by risk factor elimination.
