Abstract
Background Cancer development is aided by the role of long noncoding RNAs (lncRNAs) that act as competing endogenous RNAs (ceRNAs) absorbing microRNAs (miRNAs). We aimed to discover a novel regulatory axis in colorectal cancer (CRC) and potential biomarkers based on miR-616-3p. Materials and Methods The gene expression omnibus database was mined for differentially expressed lncRNAs (DELs) and mRNAs. LncRNAs and mRNAs were predicted using the RegRNA and TargetScan databases. A combination of the ciBioPortal and Ensemble databases was used to locate the mRNAs. Cytoscape 3.7.1-built CeRNA networks. A quantitative real-time polymerase chain reaction (qRT-PCR) was utilized to confirm the expression levels of these RNA molecules. Statistical analyses were implemented by GraphPad Prism 9. Results qRT-PCR showed (Linc01282, lnc-MYADM-1:1, and Zinc Finger Protein 347 [ZNF347]) were overexpressed whereas, (salt-inducible kinases 1 [SIK1], and miR-616-3p) were down regulated. Conclusion These results identify unique, unreported lncRNAs as CRC prognostic biomarkers, as well as prospective mRNAs as new treatment targets and predictive biomarkers for CRC. In addition, our study uncovered unexplored ceRNA networks that should be studied further in CRC.

Abstract
Adenoma detection rate (ADR) is an imperative quality measure for colorectal cancer (CRC) screening. This retrospective observational study aimed to determine the trend of polyp detection rate (PDR) and ADR in asymptomatic average- and high-risk participants in different age groups who underwent screening colonoscopy over the seven years from April 2012 to March 2019 in a tertiary gastroenterology referral center of Iran. Of 1676 participants, 51.8 % were men (mean age 52.3 years). The overall PDR and ADR were 22.7 %, and 13.5 %, respectively. Both Polyps and adenomas were more common in age groups 51-59 and ≥60 years in high-risk patients than in the corresponding groups of average-risk patients (p < 0.05). Also, both PDR and ADR were more frequent in men than in women among all studied age groups, but it was statistically significant only for the youngest age group (16.8 % versus 10.5 %, p < 0.05) for PDR and the oldest age group (19.7 % versus 13 %, p < 0.05) for ADR, respectively. The trend of total ADR was upward over 7 years in both average-risk (6.7 % to 13.3 %) and high-risk (9.8 % to 27 %) groups and across all age groups in both sexes. Multivariable logistic regression revealed that high-risk individuals had an elevated risk of adenoma compared with average-risk patients (OR: 1.6, p = 0.006). Substantial variation in thresholds of polyp and adenoma detection by age, sex, and risk categories emphasizes the need for a risk-adapted approach to CRC screening and prevention programs.

Abstract
BACKGROUND Many breast cancer (BC) patients experience psychological reactions and may have psychiatric morbidities, especially anxiety and depressive disorders. The aim of this study was to evaluate perceived stress and factors affecting this stress in women with BC in Isfahan. MATERIAL AND METHODS This analytical cross-sectional study was carried out among 197 females with BC who were newly diagnosed and referred to Isfahan Cardio-Oncology Clinic. Stress was measured by the Perceived Stress Scale Standard questionnaire. Generalized linear models (GLMs) with gamma distribution and Log Link Function were used for data analyzing. RESULTS The mean age of the patients was 48.9 ± 10.9 years, and mean perceived stress in patients was 42.8 ± 16.5. The GLMs with Gamma distribution and Log Link Function showed interaction between anxiety and surgical type and also between depression and surgical type. Patients perceived stress with anxiety*nonsurgery were significantly 2.5% higher than normal anxiety and none surgery (P = 0.004), and patients with depression*lumpectomy had significantly 2% higher stress score compared to normal depression and nonsurgery (P =0.003). CONCLUSIONS Early detection of anxiety and depression can contribute to managing the stress. Coordination between psychologists and oncologists in care and treatment of these patients is important for pursuing treatment and following the recommendations of doctors and ultimately affect the morbidity and survival in BC patients.

Abstract
Turmeric has long been used not only as an indispensable part of Asian cuisine but as a medicinal herb for dressing wounds, bites, burns, treating eye infections and acne. Curcuminoids are the active substances and their synthetic derivatives (i.e. diacetylcurcumin (DAC) and metal-curcumin complexes) possess an incredibly wide range of medicinal properties that encompass chelation capacity for multiple heavy metals, antioxidant activity, anti-inflammatory properties, cytotoxicity against cancerous cells, antiviral and antibacterial effects, antihypertensive and insulin sensitizing role, and regulatory role on apoptosis. The aforementioned properties have put curcumin on spotlight as a potential treatment for ailments such as, hepatic diseases, neurodegenerative diseases, metabolic syndrome, dyslipidemia, cardiovascular disease, auto-immune diseases, malignancies and conditions associated with metal overload. Copper is essential for major biological functions, however, an excess causes chronic ailments including neurodegenerative disorders. The fascinating approach of curcumin could alleviate such effect by forming a complex. Thus, this review aims to present available data on the effect of copper-curcumin interaction in various in vitro, ex-vivo in vivo, and clinical studies.

Abstract
The problem of food contamination is a matter of concern, which cancausehealthcomplications in consumers.Severalinternational organizations have created standard permissible limits for heavy metals in meat products. Livestock such as sheep, cattle, camels, and goats are the most important sources of protein meat in the Middle East (ME) countries. Contamination of meat products with heavy metals (HMs) may be a threat to human health. Various scattered studies have been conducted in the Middle East on the contamination of red meat and meat products with HMs however, a comprehensive review on this subject has not yet been published. This study aimed to investigate the status of HMs in both raw andprocessedtypes of meatin the ME. Theresultsof thisnarrativereviewrevealed that in many ME countries, contamination of red meat with HMs was excessive. Therefore, more monitoringoflivestockconditionsandred meat products consumed in some Middle East countries seems necessary.

Abstract
There is increasing evidence showing that microbial dysbiosis impacts the health and cancer risk of the host. An association between adherent–invasive Escherichia coli (AIEC) and colorectal cancer (CRC) has been revealed. Cyclomodulins (CMs) have been receiving increasing attention for carcinogenic changes. In this study, the incidence and features of intracellular AIEC and cyclomodulin-encoding genes were investigated and the phylogenetic grouping and genetic relatedness were evaluated. E. coli strains were isolated from the colorectal biopsies. Adhesion and invasion assays and intramacrophage cell survival test were performed to separate the AIEC isolates. Virulence genotyping for the genes htrA, dsbA, chuA, and lpfA and the cyclomodulin toxins was also conducted. In addition, phylogenetic grouping of the isolates was determined. Subsequently, repetitive element sequence-based PCR (rep-PCR) fingerprinting was performed. A total of 24 AIEC pathovars were isolated from 150 patients. The prevalence rates of htr, dsbA, and lpfA were 70.83% and that of chuA was 91.66%. The frequencies of the cyclomodulin toxins were as follows: cnf1, 29.2%; cnf2, 25%; colibactin, 29.2%; and cdt, 4.2%; cif was not found. Among the AIEC isolates, 4.2%, 4.2%, 54.2%, 29.2%, and 8.3% with phylotypes A or C, B1, B2, D, and E were identified, respectively. Left-sided colon carcinoma and adenocarcinoma T≥1 stage (CRC2) were colonized by B2 phylogroup AIEC-producing CMs more often than the samples from the other groups. Close genetic relatedness was observed in AIEC isolates with rep-PCR.

Abstract
A large number of people worldwide are affected by chronic metal exposure, which is known to be associated with different type of malignancies. The mechanisms of metal carcinogenicity are complex in nature, and excessive reactive oxygen species (ROS) generation induced by chronic metal exposure, among the other factors, has been proposed as one of the major mechanisms involved in that process. In tumor cells, ROS buildup may lead to cell death through intrinsic and extrinsic signaling pathways. Furthermore, ROS-mediated redox signaling has a crucial role in angiogenesis, which is recognized as an essential step in tumor progression. There are several redox-modulating pathways and among them, the nuclear factor erythroid2-related factor2 (Nrf2), as a sensor of oxidative or electrophilic stress, has introduced as a master regulator of cellular response against environmental stresses. Activation of Nrf2 signaling induces expression of wide variety of antioxidant and detoxification enzymes genes. Thus, this transcription factor has recently received much attention as a target for cancer chemoprevention. But meanwhile, constitutive Nrf2 activation in cancerous cells may promote cancer progression and resistance to chemotherapy. The current review describes the major underlying mechanisms involved in carcinogenesis of trace metals: copper, silver, and cadmium, with a special focus on the Nrf2 signaling pathway as a crossroad between oxidative stress and angiogenesis.

Abstract
BACKGROUND Understanding the close interaction between the specialties of cardiology and oncology is necessary for early detection of cardiovascular disease (CVD) events in cancer patients. For the risk assessment of CVD in Breast and Colorectal Cancers (CIBC) study, in the current study we aimed to validate a questionnaire for the assessment of clinical history in patients with breast cancer and colorectal cancer (CRC). METHODS We determined the content validity of the questionnaire using the 2 indexes of content validity ratio (CVR) and content validity index (CVI) to examine the specificity, simplicity, clarity, and transparency of the items. Content validity assessment was performed through a panel of experts including 2 oncologists, 5 cardiologists, 2 general practitioners, and 1 epidemiologist. The reliability of the questionnaire was estimated using Cronbach's alpha coefficient in 50 patients. Intraclass correlation coefficient (ICC) was used to examine the reproducibility of the questionnaire during 1 week. RESULTS The CRC and breast cancer questionnaire were designed with 16 and 32 questions, respectively. To obtain acceptable CVR, 5 and 11 questions were removed from the CRC and breast cancer questionnaires, respectively. Cronbach's alpha was 0.70 in the breast cancer questionnaire and 0.94 in the CRC questionnaire. All questions had a CVI of higher than 80%. The ICC in the breast cancer questionnaire ranged between 0.71 and 0.96 and in CRC questionnaire ranged between 0.78 and 0.98. CONCLUSION The validity and reliability of our newly developed questionnaire was desirable. The reliability of the breast cancer questions was acceptable and that of the CRC questions was excellent. Thus, thus questionnaire can be used in this group of patients regardless of whether the goal is cardiac care or not.

Abstract
The risk of transition to colorectal cancer (CRC) in advanced colorectal adenomas (ACAs) is about 2.5 times higher than the non-advanced ones. This systematic review and meta-analysis was performed to determine the effect of calcium and dairy products on the incidence of CAs and ACAs. Six databases were systematically searched and 37 relevant clinical trials and observational studies involving over 10,964 cases were selected for inclusion. The results showed that calcium consumption reduced the risk of CAs incidence by 8% (RR: 0.92; 95% CI: 0.89-0.96), and calcium intake as a food and dairy product reduced it about 21% (RR: 0.79; 95% CI: 0.72-0.86), and 12% (RR: 0.88; 95% CI: 0.78-0.98), respectively. However, calcium supplementation did not show a significant effect on CAs incidence (RR: 0.97; 95% CI: 0.89-1.05). Results also revealed that total calcium intake markedly reduced the risk of ACAs (RR: 0.79; 95% CI: 0.73-0.85) and the risk of recurrence of adenomas about 12% (RR: 0.88; 95% CI: 0.84-0.93). Our results suggest that natural sources of calcium such as dairy products and foods may have more effective role than supplementary calcium in terms of reducing the risk of incidence and recurrence of colorectal adenomas and advanced adenomas.

Abstract
Background: Celiac disease (CeD) is a chronic inflammatory small intestine disorder caused by an abnormal immune response to an array of the epitopes of the wheat gluten and related proteins of rye and barley in genetically susceptible individuals. Midkine (MK) is an angiogenic cytokine, chemotactic in the direction of polymorphonuclear neutrophils and macrophages, and a T-regulatory cell suppressor. So far, a possible relationship with CeD has not yet been explored. Diagnosis of CeD is based on serologic test in a clinical setting suggestive of CeD and confirmatory histologic examination of the duodenal biopsy. Sometimes, genetic testing of human leukocyte antigen (HLA)-DQ2 and HLA-DQ8 may be needed. The objective of this study was to measure and compare the circulating MK in the celiac patients and healthy individuals. Materials and Methods: Twenty newly untreated CeD cases and 20 normal controls were enrolled in this study. The enzyme-linked immunosorbent assay was used to measure the circulating MK in the celiac patients and controls. Results: There was insignificant difference in the circulating MK between the patients and controls (P > 0.05). Conclusions: The study results suggest that the MK marker does not have any diagnostic value in CeD activity to be used at the time of diagnosis or during follow-ups.

Abstract
AIM The current study aimed to determine the antifungal susceptibility profile of Candida species isolated from gastroesophageal lesions. BACKGROUND Gastroesophageal candidiasis is a common infection among HIV/AIDS patients and those who are taking PPI and H2RAs drugs. More than 20 Candida spp. can cause different types of mucocutaneous infections in humans. The present study was conducted to assess the antifungal susceptibility testing of clinical Candida spp. isolated from gastroesophageal lesions. METHODS Forty-eight clinical samples were collected from 60 patients undergoing endoscopy. All isolates were identified by molecular techniques (PCR-RFLP). The profiles of the susceptibility of Candida spp. to seven antifungal agents, i.e. amphotericin B, fluconazole, itraconazole, luliconazole, voriconazole, posaconazole, and caspofungin, were evaluated using broth microdilution. RESULTS The susceptibility profile of Candida isolates revealed 100% sensitivity to amphotericin B, caspofungin, and voriconazole. Moreover, fluconazole- (6.5%) and itraconazole-resistant (2.1%) isolates were observed. CONCLUSION With regard to the increase in fluconazole-resistant Candida species, it is necessary to determine the in vitro antifungal susceptibility pattern of clinical isolates for the best management of infection and to prevent the emergence of drug resistant isolates.

Abstract
The recent severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) disease has been accompanied by various gastrointestinal (GI) and renal manifestations in significant portion of infected patients. Beside studies on the respiratory complications of coronavirus infection, understanding the essential immunological processes underlying the different clinical manifestations of virus infection is crucial for the identification and development of effective therapies. In addition to the respiratory tract, the digestive and urinary systems are the major sources of virus transmission. Thus, knowledge about the invasion mechanisms of SARS‐CoV‐2 in these systems and the immune system responses is important for implementing the infection prevention strategies. This article presents an overview of the gut and renal complications in SARS‐CoV‐2 infection. We focus on how SARS‐CoV‐2 interacts with the immune system and the consequent contribution of immune system, gut, and renal dysfunctions in the development of disease.

Abstract
The emergence of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) in 2020, which has a substantial structural similarity to severe acute respiratory syndrome coronavirus (SARS-CoV) that caused the outbreak in 2003, is currently a threat to global health. Lung involvement is the principal clinical feature in infected patients but extra-pulmonary clinical presentations are also common. The reasons for the extensive involvement of other organs are not yet clear. Angiotensin-converting enzyme 2 (ACE2), the key peptide of renin–angiotensin system (RAS), has recently identified as a major receptor for the both SARS-CoV and SARS-CoV-2 that might be a main target of coronavirus infection. ACE2 is mainly expressed in the pulmonary pneumocytes, the small intestine enterocytes as well as the proximal tubule epithelial cells of the kidneys. In addition to the respiratory tract infection symptoms, the noticeable prevalence of gastrointestinal symptoms as well as kidney impairment in hospitalized infected patients highlights other routes of infection/transmission. In present review, we discussed the role of RAS with emphasis on ACE2 in the pathogenesis of SARS-CoV and SARS-CoV-2, particularly in gastrointestinal and kidney manifestations of the diseases.

Abstract
BACKGROUND Increased number of intestinal intraepithelial lymphocytes (IELs) is a key histological finding in the diagnosis of celiac disease (CD); however, the number of IELs in celiac patients and healthy subjects may vary from one region to another. Additionally, there are some seronegative celiac patients with a borderline histology. OBJECTIVE To determine the number of the CD3+ and CD8+ IELs T-cells in the celiac patients and healthy subjects (controls) in Isfahan. METHODS The duodenal biopsies were obtained from the celiac patients (n=15) and the controls (n=19). The total number of IELs/100 epithelial cells (ECs) were counted using the hematoxylin-eosin (H&E) staining method, and that of CD3+ and CD8+ IELs/100 ECs were counted using the immunohistochemistry (IHC) staining method. RESULTS This study defined the upper normal limit for each variable as mean + 2SD. Accordingly, the upper normal limits of the total IELs, CD3+ IELs, and CD8+ IELs/100 ECs were calculated as 37 (95% confidence intervals, CI: 33-41), 22 (95% CI: 19-25) and 12 (95% CI: 10-14), respectively. In 3 clinically CD diagnoses, the total IELs counts/100 ECs were below the upper normal limit, and the histopathological and serologic assays were negative. Nevertheless, the CD8+ IELs T-cells counts/100 ECs showed borderline values. Interestingly, these patients responded to a gluten-free diet (GFD). CONCLUSIONS The study findings suggest that in the clinically diagnosed celiac disease, IELs count/100 ECs below the upper normal limit as well as negative histopathological and serologic assays and the cell density counts of the CD8+ IELs T-cells/100 ECs could be a useful parameter in CD diagnosis and make a decision to put them on a GFD.

Abstract
Abstract- Hereditary non-polyposis colorectal cancer (HNPCC) is the most frequent autosomal dominant predisposition for development of colorectal cancer (CRC) caused by germline defects in mismatch repair (MMR) genes. Current study was aimed to find genetic variations in MSH2 and MLH1 genes and their correlation with the serum levels of Carcinoembryonic Antigen (CEA) in seven Iranian HNPCC families. Seven unrelated Iranian families including 11 HNPCC patients and 7 affected family members were selected. They were initially screened for mutations in exons 7 of MSH2 and exon 15 of MLH1 gene through polymerase chain reaction single-strand conformation polymorphism (PCR-SSCP). Positive PCR results were further analyzed through exon sequencing. Serum CEA level was determined using the ELISA test. PCRSSCP was positive in 8 out of 18 patients (44%) for exons 7 of MSH2 gene, whereas two samples (11%) demonstrated to bear a mutation in exon 15 of the MLH1 gene. Sequencing analysis of both amplified exons in positive and negative samples have confirmed no mutation in negative samples while revealed 5 and 7 novel mutations in exons 7 and 15, respectively. The mean serum concentration of CEA had a significant difference between HNPCC patients and their healthy family members. Our results demonstrated that the PCR-SSCP method has high specificity and sensitivity in the first step of mutation screening of HNPCC families. High frequency of novel alterations found in the current assay may revise the mutation screening of MSH2 and MLH1 genes and abet further assessment of their frequency among individual HNPCC patients.

Abstract
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.

Abstract
Background: Sleep is essential in maintaining health and quality of life. Inflammatory bowel disease (IBD) patients suffer from poor sleep quality. This study aimed to investigate the prevalence of sleep disturbances in Iranian IBD patients as well as the variables which can be attributed to the quality of sleep in IBD patients. Materials and Methods: Seventy-one patients filled in Pittsburg Sleep Quality Index (PSQI) questionnaire and a sociodemographic questionnaire. Disease activity was assessed by Crohn's Disease (CD) Activity Index and Ulcerative Colitis (UC) Activity Index. Regression analysis was used to identify the association between sociodemographic and disease characteristics with sleep quality. Results: We found that 32.4% of all patients, 23.1% of patients with “in remission to mild” disease, and 66.7% of patients with “moderate” disease, had poor sleep quality. CD patients were more likely to have poor sleep quality comparing UC ones in crude (odds ratio [OR] =2.14; 95% confidence interval [CI] 1.14–4.04) and adjusted (OR = 6.19; 95% CI 1.13, 34.07) models. Patients with good quality of sleep had lower systolic blood pressure and diastolic blood pressure (P = 0.09 and 0.035 respectively). Conclusion: Notable percentage of IBD patients suffer from poor sleep quality even in the remission phase. Treatment of sleep disturbances, especially in CD patients, is recommended in the IBD patient-care program.

Abstract
Background: Irritable bowel syndrome (IBS) is one of the most common functional gastrointestinal disorders with significant impact on quality of life (QOL). Considering the role of stress in the clinical course of IBS, we investigated associations between stress coping skills and symptoms and QOL in IBS patient. Methods: A cross-sectional study was conducted on 95 IBS patients referring to tertiary care centers. Coping skills (Jalowiec coping scale), IBS symptom severity scale, disease-specific QOL (IBS-QOL), and symptoms of depression and anxiety (Hospital Anxiety and Depression Scale [HADS]) were evaluated by questionnaires. Bivariate and multivariate analyses were performed to investigate association among these parameters. Results: Disease severity was positively correlated with emotive (r = 0.30) and fatalistic (r = 0.41) and negatively correlated with optimistic (r = −0.25) and confrontive (r = −0.24) coping strategies. Psychological dysfunction (total HADS score, B [95% (confidence interval) CI] = 2.61 [0.001–5.21]) and fatalistic coping (B [95% CI] = 35.27 [0.42–70.13]) were significant predictors of IBS severity. Conclusions: However, IBS patients involved in this study utilized adaptive coping strategies more frequently. Our study showed that use of maladaptive coping strategies had positive correlation with symptom severity and degree of anxiety and depression among patients, while implementation of optimistic strategies were found to be negatively correlated to severity of symptoms and also utilization of adaptive coping styles was associated with lesser degree of anxiety and depression.

Abstract
Background The assessment of health-related quality of life has become an important primary or secondary outcome measure in clinical and epidemiologic studies. The aim of this study was to validate a Persian version of Celiac Disease Questionnaire (CDQ) for Celiac disease (CD) among Iranian patients. Materials and Methods The English version of the CDQ adapted to the Persian language by a forward-backward translation by 3 professional bilingual translators (1 medical, 2 nonmedical). The content validity of translated questionnaire were studied by 5 experts who complete the validity form regarding the questionnaire. Then in a pilot study, translated CDQ completed by 81 CD patients who referred to Taleghani Hospital, Tehran. For assessing the validity and reliability of the questionnaire, confirmatory factor analysis and Cronbach's alpha coefficient have been done, using Lisrel and SPSS software. Results Of 81 CD patients entered to this study with mean age of 30.54 years old, 71.6% were female. Also, 56.8% were married and 45.7% were high educated. The mean of CDQ total score was 119.18±34. The calculated Cronbach's alpha coefficient for CDQ questionnaire was 0.9. Also, for each subgroups the Cronbach's alpha coefficient were calculated as the following; emotion: 0.92, Social: 0.89, Worries: 0.73, Gastrointestinal: 0.78. Confirmatory factor analysis indicated that all questions could be remain in questionnaire respectively. Conclusion The reliability of the Persian version of CDQ was excellent with Cronbach's alpha coefficients and Persian version of CDQ retains the psychometric properties of the original instrument and should be useful to assess outcome in studies and clinical trials involving Iranian patients with CD.

Abstract
Background: Inflammatory bowel disease (IBD) might be an immunodeficiency rather than an excessive inflammatory reaction. IBD, suspected to primary immunodeficiency diseases biobank (IBDSPIDB) as a resource for researches can help improve the prevention, diagnosis, and illness treatment and the health promotion throughout the society. Therefore, we launched the biobank of IBDSPID for the first time in Iran. Materials and Methods: This study was designed to provide the IBDSPIDB to have a high-quality DNA, RNA, and cDNA. Among of 365 patients, 39 have inclusion criteria that were as below: (1) IBD diagnosis before 5 years of age. (2) Resistance to conventional therapy of IBD. (3) Severe IBD. (4) Signs of SPID (including ear infections or pneumonia or recurrent sinus within the 1-year period; failure to thrive; poor response to the prolonged use of antibiotics; persistent thrush or skin abscesses; or a family history of PID). Results: Out of 39 patients, 51.3% were males. The mean age was 32.92 ± 15.90 years old. Ulcerative colitis (79.5%) was more than Crohn's disease. The majority of patients (50.0%) had severe IBDSPID. Resistance to drugs and consanguinity was 12.9% and 47.4%, respectively. Age at onset in 65.8% of patients was after 17 years old. Patients with autoimmune, allergy, and immunodeficiency disease history were 33.3%, 33.3%, and 10.36%, respectively. RNA and cDNA yields large quantities of high-quality DNA obtained and stored. Conclusion: Our biobank would be valuable for future genetic and molecular study to be more about the relation between IBD and PID.

Abstract
Microsatellite instability (MSI) is a molecular hallmark for some colorectal cancers (CRCs) in which short tandem repeats are prone to mutations along with DNA sequences. It is due to DNA-mismatch-repair system deficiency because of a germline/somatic mutation in mismatch-repair (MMR) genes. The germline mutations lead to Lynch syndrome (LS) while epigenetic gene silencing results in sporadic CRC tumors. We discuss in our paper the most important clinical aspects of MSI testing in CRCs. We reviewed the most reliable relevant studies and clinical trials according to their high-quality methods, particularly within two recent decades. MSI testing is used to classify CRC tumors as MSI-high (MSI-H), MSI-low, and microsatellite stable tumors. MSI-H or MMR deficient tumors have shown the best prognosis among all CRCs, so MSI testing is considered as a good prognostic marker. Moreover, it is used to identify LS among familial CRC patients. There is a diagnostic mutation in BRAF gene (V600E) by which sporadic CRCs could be distinguished from LS associated CRCs, due to its concordance with sporadic CRCs not LS. Although, some previous studies had demonstrated a predictive role for MSI testing in chemotherapy process, emerging some controversial findings in recent studies has not convinced many authors to recommend it as a routine examination to evaluate therapeutic response. Though emerging new molecular findings have opened novel windows to develop clinical management of CRC, MSI testing has remained as an excellent prognostic and diagnostic tool for CRC tumors.

Abstract
AIM To investigate whether aggressive hydration can increase the efficacy of prophylactic non-steroid anti-inflammatory drugs (NSAIDs) in prevention of post-ERCP pancreatitis. BACKGROUND NSAIDs are recommended for the prevention of PEP; however, whether aggressive hydration can have additional benefits in this regard is not known. METHODS Patients candidate for ERCP received either pre-procedural rectal diclofenac (100 mg) alone (n = 112) or in combination with aggressive hydration by lactate ringer's (n = 107) as prophylactic method. PEP was defined based on increase in serum levels of pancreatic enzymes (from baseline to 24 hours following the procedure) accompanied with symptoms. RESULTS PEP was occurred in 3 patients in the diclofenac only group and in 1 patient in the diclofenac + hydration group with no significant difference (2.7% vs. 0.9%, P = 0.622). Serum amylase levels decreased over time in the diclofenac + hydration group but not in the diclofenac only group. Also, serum lipase levels decreased more rapidly over time in the diclofenac + hydration group compared to the diclofenac only group. CONCLUSION Combination prophylactic therapy with NSAIDs plus aggressive hydration does not seem to have additional clinically important benefits in preventing PEP. Studies with larger sample of patients are required in this regard.

Abstract
Background: Inflammatory bowel disease (IBD) has a significant impact on health-related quality of life (HRQOL). This study aims to investigate the variables which can be attributed to HRQOL in IBD patients. Materials and Methods: Seventy-one patients filled in IBD questionnaire (IBDQ-32), Pittsburgh sleep quality index questionnaire, and sociodemographic questionnaire. Disease activity was assessed by Crohn's disease activity index (CDAI) and ulcerative colitis activity index (UCAI). The correlations of sleep quality, sociodemographic variables, and disease characteristics with IBDQ were investigated. Results: IBDQ-32 mean score was lower in patients who had hospitalization (P = 0.01), poor sleep quality (P < 0.001), anemia (P = 0.03), more severe disease (P = 0.01), and those who had not consumed folic acid (P = 0.01) relative to their counterparts. A multivariate regression analysis identified the predictors of decreased HRQOL as not consuming folic acid (P = 0.008), poor sleep quality (P = 0.014), and disease severity (P = 0.043). Conclusion: Impaired HRQOL was significantly associated with poor sleep quality, lack of folic acid consumption, and disease severity in IBD patients. Therefore, evaluation of folic acid level and efficacy of its supplementation in prospective studies is recommended. Treatment of sleep disturbance with pharmacological agents and nonpharmacological methods should be kept in mind as well.

Abstract
Background: Familial colorectal cancer type X (FCCX) is a subtype of mismatch repair (MMR)-proficient colorectal cancerin which the patients are clinically at risk for Lynch syndrome (LS), a common hereditary cancer predisposing syndrome. In this study, we described a new clinicopathological feature of the condition in central Iran. Materials and Methods: We designed a descriptive, retrospective study to screenat-risk colorectal cancer (CRC) patients, using Amsterdam II criteria and Molecular analysis in Isfahan (central Iran) throughout 2000-2013 period. Results: 219 early-onset (≤ 50 years) CRC patients of 1659 were selected for the evaluation. Amsterdam II criteria were positive in 45 families; of whom 31 were finally analyzed by molecular testing. MMR deficiency was detected in 7/31 probands (22.6%) as affected to LS, so 24 families (77.4%) were identified as FCCX. The mean age of the probands at diagnosis among FCCX families was 45.3 years (range 24-69) versus 38.0 years (range 31-50) in LS families. The frequency of CRC among FCCX and LS families was calculated 27.9% and 67.5%, respectively. Also, the most frequent extracolonic cancer among both FCCX and LS families was stomach by 25.5% and 30.8%, respectively. Tumor site was proximal to the splenic flexure in 20.8% and 57.1% of index CRC patients in FCCX and LS families, respectively. Conclusion: Given the relative high frequency of FCCX and its different phenotype among Iranian populations, we need to set up more advanced molecular studies for exploration of unknown molecular pathways leading to tumorigenesis in this class of CRC patients.

Abstract
OBJECTIVE : Germline mutations in mismatch repair (MMR) genes cause Lynch syndrome (LS). LS is an inherited disease, and an important consequence of MMR deficiency is microsatellite instability (MSI) phenotype. MSI phenotype influences the efficacy of 5 fluorouracil (5-FU) chemotherapy. Reproducible, cost effective, and easy to perform laboratory tests are required to include MSI detection in routine laboratory practice. Evaluation of CAT25 as monomorphic short tandem repeat sequence enables CAT25 to be an efficient screening tool among hereditary nonpolyposis colorectal cancer (HNPCC) patients compared with other methods used currently. METHODS : Based on Amsterdam II criteria, 31 patients in 31 families were shortlisted from a total number of 1,659 colorectal cancer patients. MSI status was examined in these patients using CAT25 and a commercially available Promega MSI five-marker-based detection system as well as immunohistochemical (IHC) staining of four important MMR proteins. Patients were scored as high microsatellite instable (MSI-H), low (MSI-L), or stable (MSS). MSI status determined by CAT25 single mononucleotide marker was compared with that of five mononucleotide markers, Promega commercial kit, and IHC method. RESULTS : MMR protein deficiency was observed on 7/31 probands using IHC methodology and 6/31 categorized as MSI-H using commercial kit or CAT25 single marker. The sensitivity and specificity of the CAT25 single marker were the same as those detected by five-marker Promega commercial kit in our patients. CONCLUSIONS : Based on our results, the performance of the CAT25 single mononucleotide marker for MSI status determination in our HNPCC patients is the same as that of the five-marker-based commercial kit.

Abstract
CONTEXT AND AIMS We aimed to evaluate the effectiveness of hydroalcoholic extract of Quercus brantii's nut on clinical, endoscopic, and pathological findings of patients with dyspepsia. PATIENTS AND METHODS In this randomized, double-blind clinical trial, patients with symptomatic dyspepsia who had an endoscopic evaluation for dyspepsia were included and randomized into two groups. One Group (A) received drug extract with a dose of 100 mg twice a day for 10 days. Group B, as a control group, received placebo. Immediately and 2 months after intervention, the patients were followed up, and the characteristics of their dyspepsia (severity and frequency), endoscopic and pathologic findings were reevaluated and compared. RESULTS In this trial, 13 and ten patients participated in the study in Groups A and B, respectively. Two months after intervention, ten (76.9%) and six (60%) participants referred for follow-up and endoscopic evaluation. There were no significant changes in clinical presentations after intervention (P > 0.05). Two months after intervention, clinical presentations including severity and frequency of epigastric pain had significant decrease in Group A and endoscopic evaluation indicated significant improvement in Group A (P < 0.05). Pathologic findings were similar and not significantly different in two studied groups after intervention (P > 0.05). CONCLUSIONS The findings of this trial indicated that hydroalcoholic extract of Q. brantii's nut could have delayed significant proper effect on clinical and endoscopic presentations of patients with dyspepsia. We recommend that this study should be considered as pilot one in this field. The results could be used as baseline data for more interventional studies. More surveys are needed to investigate the mechanism of extract action at molecular basis.

Abstract
BACKGROUND Colorectal cancer (CRC) is becoming one of the most complicated challenges of human health, particularly in developing countries like Iran. In this paper, we try to characterize CRC cases diagnosed < age 50 at-risk for Lynch syndrome within central Iran. MATERIALS AND METHODS We designed a descriptive retrospective study to screen all registered CRC patients within 2000-2013 in Poursina Hakim Research Center (PHRC), a referral gastroenterology clinic in central Iran, based on being early-onset (age at diagnosis ≤50 years) and Amsterdam II criteria. We calculated frequencies and percentages by SPSS 19 software to describe clinical and family history characteristics of patients with early-onset CRC. RESULTS Overall 1,659 CRC patients were included in our study of which 413 (24.9%) were ≤50 years at diagnosis. Of 219/413 successful calls 67 persons (30.6%) were reported deceased. Family history was positive for 72/219 probands (32.9%) and 53 families (24.2%) were identified as familial colorectal cancer (FCC), with a history of at-least three affected members with any type of cancer in the family, of which 85% fulfilled the Amsterdam II Criteria as hereditary non-polyposis colorectal cancer (HNPCC) families (45/219 or 20.5%). Finally, 14 families were excluded due to proband tumor tissues being unavailable or unwillingness for incorporation. The most common HNPCC-associated extracolonic- cancer among both males and females of the families was stomach, at respectively 31.8 and 32.7 percent. The most common tumor locations among the 31 probands were rectum (32.3%), sigmoid (29.0%), and ascending colon (12.9%). CONCLUSIONS Given the high prevalence of FCC (~1/4 of early-onset Iranian CRC patients), it is necessary to establish a comprehensive cancer genetic counseling and systematic screening program for early detection and to improve cancer prognosis among high risk families.

Abstract
BACKGROUND Colorectal malignancies with high microsatellite instability (MSI-H), either hereditary (Lynch syndrome) or sporadic, demonstrate better prognosis and altered response to 5FU chemotherapy. It is now recommended to perform MSI testing for all new cases of colorectal cancer regardless of being categorized as hereditary or sporadic. For MSI detection, immunohistochemistry or PCR-based protocols using a cohort of various sets of STR markers are recommended. Here we aimed to evaluate a simplified protocol using just a single STR marker, MT1XT20 mononucleotide repeat, for detection of MSI in Lynch syndrome patients. A Promega five-marker MSI testing panel and immunohistochemistry (IHC) were used as the gold standard in conjunction with MT1XT20. MATERIALS AND METHODS Colorectal patients with a positive history of familial cancers were selected by evaluating medical records. Based on Amsterdam II criteria for Lynch syndrome 20 families were short listed. DNA was extracted from formalin fixed paraffin embedded tumour and adjacent normal tissues resected from the index case in each family. Extracted DNA was subjected to MT1XT20 mononucleotide marker analysis and assessment with a commercially available five marker MSI testing kit (Promega, USA). IHC also was performed on tissue sections and the results were compared with PCR based data. RESULTS Eight (40%), seven (35%) and five (25%) cases were MSI positive using with the Promega kit, IHC and MT1XT20, respectively. Among the markers included in Promega kit, BAT26 marker showed instability in all 8 samples. NR24 and NR21 markers showed instability in 7 (87.5%), and BAT25 and MONO 27 in 6 (75%) and 5 (62.5%). CONCLUSIONS Although MT1XT20 was earlier reported as a valid standalone marker for MSI testing in CRC patients, we could not verify this in our Iranian patients. Instead BAT26 among the markers included in Promega MSI testing kit showed instability in all 8 MSI-H CRC samples. Therefore, it seems BAT26 could act well as a single marker for MSI testing in Iranian CRC patients.

Abstract
BACKGROUND Evidence exists on the association between vitamin D deficiency and inflammatory bowel diseases (IBD). AIMS To investigate whether vitamin D level is associated with disease activity and quality of life in IBD patients. METHODS This cross-sectional study was conducted on known adult IBD patients referred to an outpatient clinic of gastroenterology in Isfahan city, Iran. Disease activity was evaluated using the Simplified Crohn's Disease Activity Index and Simple Clinical Colitis Activity Index. Quality of life was assessed with the Short-Inflammatory Bowel Disease Questionnaire. Serum 25[OH]D was measured using the radioimmunoassay method. Vitamin D deficiency and insufficiency were defined as concentration of <50 and 50-75 nmol/L, respectively. RESULTS Studied subjects were 85 ulcerative colitis and 48 Crohn's disease patients (54.1% females) with mean age of 42.0 ± 14.0 years. Vitamin D deficiency and insufficiency were present in 52 (39.0%) and 24 (18.0%) patients, respectively. Thirty patients (22.5%) had active disease who, compared with patients in remission, had more frequent low vitamin D levels (80 vs. 50.4%, P = 0.005). Quality of life was not different between patients with low and those with normal vitamin D levels (P = 0.693). In the logistic regression model, low vitamin D was independently associated with active disease status, OR (95% CI) = 5.959 (1.695-20.952). CONCLUSIONS We found an association between vitamin D deficiency/insufficiency and disease activity in IBD patients. Prospective cohorts and clinical trials are required to clarify the role of vitamin D deficiency and its treatment in clinical course of IBD.

Abstract
BACKGROUND Microsatellite instability (MSI) is a mutational signature that is the hallmark of Lynch syndrome, and MSI testing is a cost-effective method to screen the disease. Since there is no enough data about MSI status and associated clinicopathologic features of hereditary nonpolyposis colorectal cancer (HNPCC) in Iran, our study is a new trial to describe them in center of Iran (Isfahan). MATERIALS AND METHODS It is a descriptive retrospective study to screen HNPCC families using Amsterdam II criteria in Central Iran within 2000-2013. For MSI testing, we used a commercially available kit evaluating mononucleotide markers (BAT-25, BAT-26, MON0-27, NR-21 and NR-24). After a fluorescent multiplex polymerase chain reaction amplification of the markers, samples were sequenced to fragment analysis. Data analysis was performed using SPSS 16 software (SPSS Inc., Chicago, IL, USA). RESULTS Overall, 31 of 45 screened HNPCC families were eventually included to MSI testing. Totally, 9/31 patients (29.0%) showed MSI in their tumor tissues. BAT-26 was the most instable marker with instability in 7/24 MSI tumors (29.2%). The mean age at diagnosis in microsatellite stable (MSS), MSI-Low (MSI-L), and MSI-High (MSI-H) probands was respectively 44.7 (standard deviation [SD] = 11.83), 51.7 (SD = 16.17), and 36.0 (SD = 3.41) years. The most common tumor sites in MSS, MSI-L, and MSI-H probands were rectosigmoid (∼72.8%), rectum (66.7%) and right colon (50.0%), respectively. Of 186 cancer patients among 31 HNPCC families, 86 patients (46.2%) had colorectal cancer (CRC) and 100 patients (53.8%) had extracolonic cancers. The average of CRC affected members among MSS, MSI-L, and MSI-H groups of our HNPCC families was 2.2 (SD = 1.30), 3.3 (SD = 3.21), and 4.7 (SD = 2.42) patients per family, respectively. Stomach with 18.3% and 26.7% of all extracolonic cancers were most common involved organ in MSS and MSI-H families, respectively. CONCLUSION Our different molecular results could be suggested to describe HNPCC families based on some new molecular mechanisms leading to MSS HNPCC phenotypes. Meanwhile, more evaluations within our population are recommended.

Abstract
BACKGROUND Hereditary non-polyposis colorectal cancer (HNPCC) is a common hereditary cancer predisposing syndrome has molecular and clinicopathological features still have remained ambiguous within Iranian populations. We discuss in this article some molecular and clinicopathological features of the condition. METHODS The study was a descriptive retrospective and designed on 1659 colorectal cancer (CRC) patients were screened based on early-onset disease and Amsterdam II criteria during 14 years (2000-2013). Immunohistochemistry (IHC) staining was set up to detect expression of mismatch repair (MMR) genes on paraffin-embedded tissue sections of 31 HNPCC-CRC tumors. SPSS 19 software was used to analyze the data. RESULTS IHC-MMR staining was absent in 7/31 individuals (22.6%) of which 4 cases showed IHC-Absent (IHC-A) in both MSH2 and MSH6 (57.1%), in 2 cases both MLH1 and PMS2 had negative staining (28.6%), and just in one case, MSH6 was defective (14.3%). The frequency of CRC among IHC-A and IHC-Present (IHC-P) families was 67.5% and 27.9%, respectively. Also the most frequent extracolonic cancers in IHC-A group were: stomach (10%), small bowel (5%), and prostate (5%); and in IHC-P group: stomach (18.4%), lung (10.9%), and breast (7.5%). Average age of IHC-A individuals at diagnosis was 38.0 versus 45.3 years in IHC-P individuals. Overall, 20.8% and 57.1% of our index CRCs were localized proximal to the splenic flexure in IHC-P and IHC-A groups, respectively. CONCLUSION Given the lack of enough information about molecular aspects of hereditary cancer syndromes like HNPCC in Iran, more evaluations are necessary on larger samples using complementary techniques such as MSI-testing and mutation analyses.

Abstract
AIM The present study aimed to study the immunological changes seen in the intestinal epithelium of the celiac patients could also be detected in the peripheral blood lymphocyte populations. BACKGROUND Celiac disease (CD) is a small bowel enteropathy caused by permanent wheat gluten intolerance. One of the earliest signs of CD is an increase in the numbers of the intestinal intraepithelial lymphocytes (iIEL). PATIENTS AND METHODS In this case-control study, totally 13 untreated subjects with acceptable criteria for CD without any complication and 16 healthy subjects without any positive criteria for CD were selected. Peripheral blood T cells were analyzed by two-color flow cytometry in both groups. RESULTS The mean age of patients was 33.6 ± 3.4 years and two patients had Marsh IIIB, five patients had Marsh IIIA and six patients had Marsh II histology class. The mean percentages of the TCR(+) T cells in the patients were significantly higher than the controls (p=0.015). However, the mean percentages of the αβTCR(+) T cells were significantly lower in the untreated patients than the controls (p=0.025). There were no significant difference between the mean percentages of lymphocytes expressing the CD3, CD4 and CD8 molecules in the patients and the controls. CONCLUSION The change in the percentages of the peripheral blood T cells expressing the γδTCR and αβTCR in the celiac patients could be used in conjunction with the other serological markers to identify new CD cases.

Abstract
BACKGROUND Magnetic resonance cholangiography (MRC) has gained popularity for diagnosing primary sclerosing cholangitis (PSC). We determined the accuracy of MRC compared with endoscopic retrograde cholangiography (ERC) for diagnosing PSC. MATERIALS AND METHODS This retrospective case-control study was conducted on patients referred to an outpatient gastroenterology clinic from 2001 to 2013. Patients with established diagnosis of PSC who had undergone MRC and ERC within a 6-month interval were included. Controls were selected from patients who had undergone imaging for reasons other than PSC evaluation. Disease outcome at the study time and liver biochemistry data at diagnosis and 1-year thereafter were retrieved. Diagnostic accuracy of MRC in comparison with ERC was evaluated. RESULTS A total of 46 definite PSC patients (age at diagnosis = 36.8 ± 11.6 years, 33 male) were found. Diagnostic imaging for PSC was ERC alone in 12, MRC alone in 23, and ERC plus MRC in 11 patients. Controls were 89 patients mostly with bile stones. The sensitivity, specificity, and positive and negative likelihood ratios of MRC was 90.9%, 95.5%, 20.23, and 0.10, respectively. Early PSC was found more frequently by MRC compared with ERC (30.4% vs. 8.3%, P = 0.146). No significant difference was found between imaging modalities with regards to patients' outcome (P = 0.786) or liver biochemistry at diagnosis or 1-year thereafter (P >0.05). CONCLUSION Starting diagnostic imaging for PSC with MRC seems better and may provide diagnosis of PSC at its earlier phase. Further studies with larger sample of patients and longer follow-ups are warranted.

Abstract
Background: Increasing antibiotic resistance of Helicobacter pylori (H. pylori) which is associated with diseases of the upper gastrointestinal tract, has made alternative treatments necessary. This study compares the efficacy of adding N-acetyl cysteine (NAC) to standard regimen for H. pylori eradication. Materials and Methods: We conducted a randomized, open-label trial, comparing the efficacy of 14 days of quadruple therapy with Amoxicillin, Bismuth citrate, Omeprazole, Clarithromycin (group A) versus 14 days of above regimen plus NAC (group B) in adult patients with dyspepsia. Primary objective was H. pylori eradication. Compliance and side effects were determined by questionnaires. Our analysis was by intention-to-treat (ITT) and per-protocol. This study is registered with www.IRCT.ir, number: IRCT201201078634N1. Result: A total of 121 participants aged 21-76 years with a mean age of 44.5 ± 14.1, and 52.9% female, were randomly allocated a treatment: 60 with 14-day standard therapy and 61 with 14-day standard therapy with NAC. The eradication rate in groups A and B with ITT analyses was 49/60 (81.7%; 95% [confidence intervals] CI = 71.6-91.8%) and 50/61 (82%; 95% CI = 72-91.9%), respectively (P = 0.96). In per-protocol analysis, the rate of H. pylori eradication in groups A and B was 45/54 (83.3%; 95% CI = 73.1-93.6%) and 45/53 (84.9%; 95% CI = 74.9-94.9%), respectively (P = 0.82). Minor well tolerated side effects were reported in 15 (34.9%) and 21 (35.6%) patients of groups A and B, respectively, and only one therapy cessation in group A was created. Conclusion: Standard 14-day triple-drug therapy with NAC is not preferable to standard drug regimens for H. pylori infection.

Abstract
Coeliac disease (CD) is a highly prevalent autoimmune disorder that is triggered by the ingestion of wheat gluten and related proteins in genetically susceptible individuals. The CD is associated with human leucocyte antigen (HLA) genes particularly with HLA-DQ alleles encoding HLA-DQ2 and DQ8 proteins. To define risk and severity alleles for CD, a total of 120 definite CD patients and 100 healthy controls were genotyped for HLA-DQB1 gene. HLA-DQB1 genotyping was performed in all patients and controls using PCR-SSP technique, and to evaluate the clinical relevance of testing for HLA-DQB1 and determining absolute risk of disease, prevalence-corrected positive predictive value and prevalence-corrected negative predictive value (PcPPV and PcNPV) were calculated. Our results for a first time show that DQB1*02:00 and DQB1*03:02 alleles and DQB1*02:01/03:02 genotype very significantly associated with increased risk of patients with CD, and DQB1*03:01,4 allele provides protection against CD in Iranian patients. Furthermore, the PcPPV for DQB*02:01 and 03:02 alleles in CD were 0.014 and 0.012, respectively, and the highest absolute risk presented by DQB*0201/0302 genotype (PcPPV = 0.079) and 98% of patients with CD carried DQB1*02:01/x or DQB1*03:02/x genotype. The results also clearly demonstrated that the DQB1*02:01 allele significantly associated with severity of CD, while DQB1*03:02 allele associated with mild form of CD. These results suggest that clinically suspected individuals for CD and first-degree relatives of patients with CD to be screened for HLA-DQB*0201 and DQB*0302 alleles for possible early diagnosis and treatments.

Abstract
BACKGROUND Cadmium and lead compounds are classified as human carcinogens by several regulatory agencies. Twenty five percent of all cancer-related deaths are attributed to gastrointestinal cancers (GI Ca). We investigated the levels of 2 different heavy metals (Cd and Pb) in the soils of the Lenjanat region, Isfahan province, Central Iran where intensive agriculture is surrounded by different industries like steel and cement-making factories and mining and gastrointestinal cancers are very common in this province. MATERIALS AND METHODS Two hundred topsoil samples (0-20 cm depth) were collected from agricultural and non-agricultural soils of the region and were analyzed for heavy metals. The metal contents were determined by flame atomic absorption spectrometry. RESULTS The findings of this study showed that frequency of gastrointestinal cancers in the study area have been increased in the recent years. Results of soil samples in this region showed that the mean concentration of Pb and Cd were more than 16 and 1 mg kg(-1), respectively. The total Cd concentration in most of the samples exceeded the suggested Swiss thresholds (0.8 mg kg(-1)) but the mean value of Pb concentration in soil was less than the threshold of 50 mg kg(-1) set by Swiss Federal Office of Environmental, Forest and Landscape. Compared to the threshold values for heavy metals (Cd and Pb) in soils, data showed that the studied fields were contaminated especially by Cd. CONCLUSION High heavy metals content in the soils seems to play an important etiological role in the carcinogenesis. Excessive accumulation of heavy metals in agricultural soils may not only result in soil contamination, but also lead to elevated heavy metal uptake by crops, and thus affect food quality and safety. Thus, analyzing heavy metals content in crops, water and dust could provide us a better insight to solve the problem.

Abstract
Autosomal dominant polycystic kidney disease (ADPKD) is an inherited disorder associated with multiple cyst formation in the different organs. Development of pancreatic cyst in ADPKD is often asymptomatic and is associated with no complication. A 38-year-old man with ADPKD was presented with six episodes of acute pancreatitis and two episodes of cholangitis in a period of 12 months. Various imaging studies revealed multiple renal, hepatic and pancreatic cysts, mild ectasia of pancreatic duct, dilation of biliary system and absence of biliary stone. He was managed with conservative treatment for each attack. ADPKD should be considered as a potential risk factor for recurrent acute and/or chronic pancreatitis and cholangitis.

Abstract
Background: To setup a non-invasive genetic screening method for colorectal cancer, we evaluated the promoter methylation status of secreted frizzled-related protein1 (sfrp1) in stool samples of colorectal cancer with respect to a series of healthy individuals, using methylation-specific polymerase chain reaction. Materials and Methods: In stool samples from 25 patients with colorectal cancer and 25 healthy control subjects, isolated DNA was treated with sodium bisulfite and analyzed by methylation-specific polymerase chain reaction with primers specific for methylated or unmethylated promoter sequences of the SFRP1 gene. Result: Methylation of the SFRP1 promoter was present in the stool DNA of patients with colorectal cancer. A sensitivity of 52% and specificity of 92% were achieved in the detection of colorectal neoplasia. The difference in methylation status of the SFRP1 promoter between the patients with colorectal neoplasia and the control group was statistically highly significant (P = 0.006). Conclusions: The results indicate that this DNA stool test of methylation of the SFRP1 promoter is a sensitive and specific method. It is assumed that the test is potentially useful for the early detection of colorectal cancer.

Abstract
BACKGROUND There is a lack of data on familial aggregation of colorectal cancer (CRC) in Iran. We aimed to determine the frequency of hereditary nonpolyposis colorectal cancer (HNPCC) and familial colorectal cancer (FCC) and to determine the frequency of extracolonic cancers in these families in Isfahan. METHODS We reviewed documents of all patients with a pathologically confirmed diagnosis of CRC admitted to Isfahan referral hospitals between 1995 and 2006. We also studied our CRC registry at Poursina Hakim Research Institute from 2003 to 2008. We found HNPCC and FCC families based on the Amsterdam II criteria and interviewed them for family history of CRC and extracolonic tumors. The family history was taken at least up to the second-degree relatives. RESULTS During 1996 to 2008, a total of 2580 CRC cases have been diagnosed. We found 14 HNPCC and 53 FCC families. Mean age of CRC at diagnosis was 48.0 ± 14.6 and 49.0 ± 13.9 years in the HNPCC and FCC families, respectively (p > 0.05). The total numbers of observed extracolonic tumors were 70 (21.6%; mean age = 53.6 ± 11.0 years) and 157 (13.8%; mean age = 54.8 ± 18.0 years) in HNPCC and FCC families, respectively (p > 0.05). CRC was respectively found in 52 and 76 members of the HNPCC and FCC families, revealing the frequency of HNPCC and FCC as 2.0% (52/2580) and 2.9% (76/2580), respectively. CONCLUSIONS We found a relative high frequency of HNPCC (2.0%) and FCC (2.9%) among CRC cases in our society and high incidence of extracolonic tumors in their families. Further studies focusing on molecular basis in this field and designing a specific screening and national cancer registry program for HNPCC and FCC families should be conducted.

Abstract
Colorectal cancer (CRC) is among the major causes of cancer-related morbidity, mortality, and human health problem worldwide. Single-nucleotide polymorphisms (SNPs) in different genes are reported to be effective in increased risk of CRC in different ethnic population. We conducted a case-control study in patients diagnosed with sporadic colorectal cancer (n = 115) and healthy controls based on colonoscopy evidences (n = 120).In this replicative study, we aimed to investigate the association of two previously reported polymorphisms, rs6983267 and rs4444903, with sporadic colorectal cancer in a subset of Iranian patients. Genotyping was performed via polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay. A significant relation was found between rs6983267 variant in the 8q24 region and colorectal cancer. The distribution of G/G genotypes among sporadic CRC patients was more frequent than that in the control group (P value = 0.001). The frequency of the G allele in the colorectal cancer patient group was also higher than that in the control group (65% vs. 48%; P value = 0.001). Compared with GG genotype, individuals with G/T and T/T genotypes had lower risk to develop sporadic CRC (OR = 0.357, 95% CI = 0.201-0.635). For the rs4444903 SNP, no significant association (P value = 0.149) was found with colorectal cancer risk. In conclusion, our findings suggest that the 8q24 rs6983267 SNP may play a pivotal role in the development of sporadic CRC in Iranian population. Therefore, it may be included as a potential genetic susceptibility marker for sporadic CRC.

Abstract
There is a growing interest of clinical and epidemiological researches in the field of functional gastrointestinal disorders in our society. Accordingly, validated and culturally adapted instruments are required for appropriate measurement of variables specially the quality of life. The aim of our study was the linguistic validation of the Irritable Bowel Syndrome-Quality of Life questionnaire (IBS-QOL) for Iranian IBS patients with Persian language. Following the standard forward-backward translation method, the IBS-QOL was translated into the Persian language and completed by 141 IBS patients. Patients also completed the IBS Symptom Severity Scale (IBS-SSS) and Hospital Anxiety and Depression Scale (HADS). One-week retest was performed on 30 randomly selected patients. Internal consistency and test-retest reliability were assessed using Cronbach's alpha and intraclass correlation coefficient (ICC), respectively. To analyze the discriminant validity, the IBS-QOL scores was correlated to the IBS-SSS and HADS scores. According to the results, reliability analyses were acceptable for all of the IBS-QOL domains (Cronbach's alpha=0.68 to 0.90 and ICCs=0.77 to 0.91). Discriminant validity was supported by the presence of correlations of the IBS-QOL scores with disease severity (r = -0.628), depression (r = -0.692), and anxiety (r = -0.711) scores; P < 0.001. These results indicate that the Persian version of the IBS-QOL is a reliable instrument with sufficient psychometric requirements to assess quality of life in Iranian IBS patients with Persian language.

Abstract
BACKGROUND A number of changes in the duodenum are associated with celiac disease (CD), and can be identified endoscopically. Their accuracy becomes crucial as CD markers. This study aimed to determine the diagnostic value of endoscopic markers and to find ways of applying them in the diagnosis of CD. METHODS Seven hundred and sixty-five consecutive patients referred for upper gastrointestinal endoscopy during 18 months were enrolled in the study. The second part of the duodenum was inspected carefully, and biopsies were taken in all patients to detect histologic changes suggestive of CD. RESULTS Endoscopic features suggestive of CD were observed in 69 (10.6%) patients; of these, 7 (10.1%) patients were finally diagnosed to have CD. Of the remaining 578 patients in whom the endoscopic markers were not seen, 2 (0.3%) patients were found to have CD. The overall sensitivity, specificity, PPV and NPV of the markers for the diagnosis of CD were 77%, 91%, 10% and 99%, respectively. Of the 9 patients who had CD, 5 had typical symptoms of CD and 4 had atypical features of CD. CONCLUSIONS Owing to high NPV of endoscopic markers, a careful observation of the second part of duodenum plays an important role in the diagnosis of CD. In patients in whom endoscopic markers are observed, biopsies are indicated; routine duodenal biopsy in all patients cannot be advocated.

Abstract
Blue rubber bleb nevus syndrome (BRBNS) is a rare disorder characterized by cutaneous and gastrointestinal (GI) venous malformations. The treatment of BRBNS is primarily supportive and ablative. Ablative therapy involves endoscopic or surgical treatment of GI venous malformations. We describe a 20-year-old woman who had multiple venous malformations all over the GI tract as well as cutaneous lesions. She had suffered from several episodes of melena, chronic anemia and fatigue for 10 years, which were treated temporarily by iron supplementation and blood transfusion. The endoscopic examination of the GI tract and total colonoscopy revealed multiple bluish sessile and polypoid venous malformations 2-3 cm in size throughout the GI tract. Argon plasma coagulation (APC) and polypectomy was done for all gastric and colonic lesions, respectively. Ileoscopy showed a large wide base vascular polypoid lesion at about 70 cm from the ileocecal valve with active bleeding; this was removed by snare polypectomy. One week later, she was discharged in good condition. At about 6 months' follow up she did not report any bleeding attack. Endoscopic polypectomy can be useful in patients with large and polypoid lesions of BRBNs which are not controlled with supportive therapy. Further experience is needed to evaluate the risks versus benefits of this approach.

Abstract
Idiopathic inflammatory bowel diseases (IBDs) significantly affect the quality of life of sufferers. Improved quality of life and patient symptom management may be achieved through integrating psychological/behavioral interventions with pharmacologic treatments. Here is our experience with hypnotherapy as an adjuvant management for an 18-year-old female with Crohn's Disease (CD) in remission (patient I) and a 24-year-old female with CD in active phase (patient II). The patients participated in 12 weekly one-hour sessions of hypnotherapy. Gut-directed, ego-strengthening, and post-hypnotic suggestions and immune-directed imaginations were used. After the hypnotherapy course, symptoms, psychological state, and quality of life improved in patient I, but not patient II (according to questionnaires). After a 6 month follow-up, symptoms and quality of life were the same as at the end of hypnotherapy sessions in both patients. The patients reported the greatest benefit of hypnotherapy was in helping them to cope better with their disease and also in improving their psychological state. Hypnotherapy may improve quality of life of IBD patients in remission and help them to cope better with their disease. Well-designed controlled clinical trials are needed in this field.

Abstract
BACKGROUND A variety of neurological disorders have been reported in association with celiac disease (CD) including epilepsy, ataxia, neuropathy and multifocal leucoencephalopathy. The purpose of this study was to assess the prevalence of CD among epileptic patients. METHODS Our study population consisted of 108 consecutive unexplained epileptic patients from Epilepsy Clinics. Patients who were able to give informed consent were invited to undergo screening for CD in a gastroenterology clinic. The diagnosis of CD was determined by IgA anti-tissue transglutaminase (t-TG) antibodies and by small intestine biopsy. Histopathologic changes were interpreted according to the Marsh classification. RESULTS A total of 108 consecutive epileptic patients (72 females, 36 males) ranging from 2-64 years (mean: 23.44, SD: 12.1) were studied. Positive IgA anti t-TG were detected in 4 of 108 epileptic patients (3.7%), while the known prevalence of CD in the study area was 0.6%.The intestinal biopsy confirmed the diagnosis of CD in three patients and was interpreted as Marsh I. In the other patient, small intestinal biopsy indicated only slightly increased number of intraepithelial lymphocytes. There was a significant difference between patients with CD and without CD for two symptoms: diarrhea and aphtous lesions (p<0.05). CONCLUSION Prevalence of CD was increased among patients with epilepsy of unknown etiology. It is important to investigate CD in any patient with idiopathic epilepsy even in the absence of digestive symptoms.

Abstract
1. Generically based pharmaceutical systems exist in a few countries of the world, such as Iran. Most developed countries have free market pharmaceutical systems. Drug-related problems (DRP) have been reported mostly in the Western world but few data are available for generic systems. In this study, we tried to measure the prevalence of drug-related problems leading to hospital admissions in Isfahan, Iran. 2. One thousand consecutive hospital admissions in three major teaching hospitals were studied for a period of 6 months for the presence of DRP as a cause of hospital admissions. Two subcategories of DRP were considered: (i) drug therapy failure; and (ii) adverse drug reactions. Preventability and outcome measures were also assessed. Medications responsible for DRP were classified according to the Anatomic Therapeutic Chemical (ATC) classification of the World Health Organization. 3. Of the 1000 admissions studied, 115 (11.5%) were owing to DRP, 81% as a result of drug therapy failure and 19% as adverse drug reactions. A total of 106 out of the 115 DRP cases (92%) were either preventable or probably preventable, most of which had to do with either prescriber or patient error. An overview of DRP showed that 58.3% resulted in complete recovery, 33.9% in relative recovery and 7.8% in death. Close to 1% of hospital admissions resulted in DRP-related deaths. 4. The overall prevalence of hospital admissions caused by DRP is similar to that in free market pharmaceutical systems. The high preventability rate of these problems should alert clinicians and policy makers to design strategies to curtail this. Also, reasons for differences in subtypes of DRP between the results of this study and those of the literature from free market systems needs to be investigated further.

Abstract
AIM: To investigate some possible etiologies of achalasia by screening patients with achalasia for some autoimmune diseases such as thyroid disease.
METHODS: We examined 30 known cases of achalasia (20 females, 10 males). Their age ranged 15-70 years. All of them were referred to our institute for treatment. Their sera were evaluated to detect some possible associations with rheumatoid disease, thyroid disease, inflammatory process, anemia, etc.
RESULTS: Seven out of 30 patients (23%) had thyroid disease including four patients with hypothyroidism (13.3%), two patients with hyperthyroidism (6.6%), and one had only thyroid nodule but was in euthyroid state (3.3%). Two of these hypothyroid patients had no related clinical symptoms (subclinical) and two had clinical manifestations of hypothyroidism. There were no correlations between the intensity of thyroid diseases and the severity of achalasia symptoms.
CONCLUSION: The etiology of achalasia is unknown although autoimmunity has been implicated and is supported by several studies. Thyroid disease presents concomitantly with achalasia in about one fourth of our patients who may have a common etiology.

Abstract
AIM: To evaluate the gastric emptying inhibitory effects of sugar and levodopa on H pylori eradication period.
METHODS: A total of 139 consecutive patients were randomized into 6 groups. The participants with peptic ulcer disease or non-ulcer dyspepsia non-responding to other medications who were also H pylori-positive patients either with positive rapid urease test (RUT) or positive histology were included. All groups were pretreated with omeprazole for 2 d and then treated with quadruple therapy regimen (omeprazole, bismuth, tetracycline and metronidazole); all drugs were given twice daily. Groups 1 and 2 were treated for 3 d, groups 3, 4 and 5 for 7 d, and group 6 for 14 d. Groups 1 to 4 received sugar in the form of 10% sucrose syrup. Levodopa was prescribed for groups 1 and 3. Patients in groups 2 and 4 were given placebo for levodopa and groups 5 and 6 received placebos for both sugar and levodopa. Upper endoscopy and biopsies were carried out before treatment and two months after treatment. Eradication of H pylori was assessed by RUT and histology 8 wk later.
RESULTS: Thirty patients were excluded. Per-protocol analysis showed successful eradication in 53% in group 1, 56% in group 2, 58% in group 3, 33.3% in group 4, 28% in group 5, and 53% in group 6. Eradication rate, patient compliance and satisfaction were not significantly different between the groups.
CONCLUSION: It seems that adding sugar or levodopa or both to anti H pylori eradication regimens may lead to shorter duration of treatment.
