    As the incidence of inflammatory bowel diseases (IBD) increases in the newly industrialized countries, the health and financial burden of disease also increase. These changes make the role of IBD biomarkers further crucial. Serum calprotectin, as a novel blood-based biomarker of IBD, has been investigated in several investigations. Yet, there is no consensus regarding its clinical utility. We searched the electronic database, including PubMed, EMBASE, Scopus, and Web of Science up to the end of 2018 to find how serum calprotectin associates with the disease characteristics in IBD. The search terms included: inflammatory bowel diseases, IBD, Crohn Diseases (CD), Ulcerative Colitis (UC), calprotectin, serum, and blood. Based on our review, a biomarker role has been suggested for serum calprotectin in IBD, as significant associations were found between serum calprotectin and disease burden, prognosis, and relapse. A complementary role to fecal calprotectin has also been suggested for serum calprotectin. On the other hand, considering a significant correlation between serum calprotectin and serum CRP, but not fecal calprotectin, serum calprotectin could be more representative of systemic inflammation than an intestinal inflammation. Consequently, further researches are needed to unwrap the potential of serum calprotectin as a blood-based biomarker in IBD.Keywords: Inflammatory bowel diseases, Serum calprotectin, Biomarker.(Please cite as: Azramezani Kopi T, Shahrokh SH, Mirzaei A, Asadzadeh Aghdaei H, Amini Kadijani A.

    Aim

    The aim of this study was to investigate the effects of eight weeks aerobic and resistance exercise on blood lipid profile in elderly with non-alcoholic fatty liver disease (NAFLD).

    Background

    Increased sedentary have a potential role in the development of NAFLD. Exercise training as an effective strategy to reduce NAFLD is presented.

    Methods

    In a randomized clinical trial study, thirty nine elderly patients with NAFLD were enrolled and were randomly divided in three groups. Aerobic groups (AG, n=13), resistance group (RG, n=13) and control group (CG, n=13). AG participated in an 8-week aerobic training (three 45-min sessions per week at 55-75% of HRR (heart rate reserve)). RG participated in an 8-week resistance exercises (three 45-min sessions per week at 50-70% of 1RM (one-repetition measure). Blood lipid profile of patients were evaluated baseline and after eight weeks.

    Results

    At baseline, there were no differences between the two groups. In two group, cholesterol and low density lipoprotein (LDL) of blood of elderly follow eight weeks aerobic training with p=0.02 and p=0.02 were decreased, respectively. Also, High density lipoprotein (HDL) was improved follow aerobic training (p=0.008). However, the aerobic and resistance training were not effective on triglyceride (TG).

    Conclusion

    aerobic training was more effective than resistance training in improving the blood lipid profile in elderly with NAFLD and can role in management of this condition.Keywords: Aerobic training, Aging, Resistance training, Non-alcoholic fatty liver disease, Lipid profile.(Please cite as: Ghamarchehreh ME, Shamsoddini AR, Alavian SM.

    Aim

    We designed this study to evaluate the effectiveness of the combination of topical rectal therapy with biofeedback in treatment of solitary rectal ulcer compared to single biofeedback therapy.

    Background

    Biofeedback therapy is an appropriate treatment for patients with solitary rectal ulcer syndrome (SRUS) but it seems that it is not effective alone. Topical medical therapies are supposed to have an additive role to biofeedback.

    Methods

    This randomized, controlled trial was conducted on 63 patients with SRUS. Patients were randomly enrolled into two groups of combination and single therapy. The patients in combination group (n=31) received biofeedback plus a topical therapy (an enema contained dexamethasone, sulfasalazine and bismuth) and the patients in single therapy group (n=32) were treated with biofeedback alone.

    Results

    Endoscopic responses to treatment in the combination and single groups were 80% and 50%, respectively (P<0.05).  Clinical improvement in symptoms such as difficulty to evacuate, digitation to evacuate, feeling of incomplete evacuation, time to need to evacuation and life style alternation were significantly better in treated group by combination therapy than single therapy. Regarding to the mean total score based on all subjective parameters, the results were also significantly better in the treated group by combination therapy.

    Conclusion

    Topical anti-inflammatory therapies in combination with biofeedback is an efficient treatment for patients with SRUS.Keywords: Biofeedback, SRUS, Endoscopic responses.(Please cite as: Abdi S, Tavakolikia N, Yamini M, Bagheri M, Sadeghi A, Pourhoseingholi MA, et al.

    Aim

    We assessed the knowledge of physicians regarding diagnosis and treatment of celiac disease (CD).

    Background

    Specialists as the main therapist group of CD patients may play crucial role in the diagnosis and treatment of CD. Therefore, training and ensuring their capabilities is important.

    Methods

    The population was specialists including Gastroenterologist, GI fellow, consultants, residents and general practitioners graduated in Medical Sciences Universities in Iran. The examination was the experts made and aimed to assess the educational needs of physicians and explore their failures in the diagnosis and treatment of CD with the key feature approach. Data was collected using a questionnaire that its validity and reliability was confirmed by experts (r = 91.6%). The total score was 150 with the classification of participants to the following categories: good (112- 150), intermediate (39-112) and weak ( ?38).

    Results

    Out of 300 participants, 197 questionnaires were returned (Response rate = 66%). The mean age of the participants was 42.67 years (SD = 7.9 years) with majority were male (63.6%). Average score of participates who had less than three year’s experience was significantly higher than others (P?0.05). Only 12.1% and 9.8% of specialists have got the excellent score for diagnosis and treatment, respectively.

    Conclusion

    It may conclude that specialists have had performance gap and around 90% needed training based on the principles of instructional design in order to improve their knowledge and skills to do and practice their assigned tasks. Therefore, development of training packages according to the principles of instructional design is suggested.Keywords: Instructional design, Celiac Disease, specialists, need assessment.(Please cite as: Barzegar F, Rostami-Nejad M, Rostami K, Ahmadi S, Mohaghegh-Shalmani H, Sadeghi A, et al.

    Aim

    This study compares the effects of two drug regimens for Helicobacter pylori (H. pylori) infection resistant to the first line drug regimen among patients referred to Ilam clinics, Iran.

    Background

    Single drug regimen is not effective for H. pylori infection and therefore, application of triple or quadruple drug regimens are currently applied.

    Methods

    This study was performed by a before-after comparative method and patients were randomly selected among those consecutively referred to Ilam gastrointestinal clinics. Patients with failure in the first line treatment, were randomly divided into two equal groups and each group was treated by one of the PPI+Amoxicillin+Rifampicin or PPI+Amoxicillin+Levofloxacin drug regimens for 14 days. Six weeks after treatment, patients were tested for H. pylori stool antigen and the results were compared between two groups.

    Results

    In this study, 100 patients including 49 (49%) men and 51 (51%) women were examined. There was no statistical difference between the two groups for gender, age and living location at the start of study (p = 0.068). The mean age of the patients was 44.55 ±15.1 years old ranging from 17 to 85 years. Response to treatment among the levofloxacin group, was 90% and in rifampicin group 72% with a significant difference (p<0.04).

    Conclusion

    The response rate of H. pylori infection to the Levofloxacin based regimen was 90%; however, the application of rifampicin in combination with other drugs against H. pylori infection (72% response rate), should be limited to reduce the possibility of drug resistance in case of tuberculosis infection.Keywords: Helicobacter pylori, Levofloxacin, Rifampicin, PPI, Drug resistance.(Please cite as: Abangah GH, Raughani A, Asadollahi P, Asadollahi KH.

    Aim

    The aim of this study is to examine the relationship between dietary patterns and the risk of Colorectal Cancer (CRC) and adenomas.

    Background

    Dietary patterns have been shown to be associated with risk of CRC, but there are a few data on this context and its relationship with risk of colorectal adenomas as the precursors of the CRC.

    Methods

    This hospital-based case-control study was conducted in three major general hospitals in Tehran province, Iran. Data was collected (October 2016 to May 2018) from 129 colorectal cancer and 130 colorectal adenoma patients that confirmed by pathology and colonoscopy findings and 240 controls with non-neoplastic conditions and not afflicted with diet related chronic diseases. Dietary data were evaluated by 147-items semi-quantitative food frequency questionnaire. Multivariate logistic regression was used to estimate the relationship between dietary patterns and risk of colorectal cancer and colorectal adenoma.

    Results

    Three dietary patterns (healthy, western and traditional) were derived. After adjusting for confounders, the Healthy dietary pattern was associated with a decreased risk of Colorectal Cancer (OR=0.22, 95% CI=0.14-0.37) and Colorectal Adenoma (OR=0.43, 95% CI=0.27-0.69). Higher intake of the Westernized pattern was positively associated with risk of Colorectal Cancer (OR=3.5, 95% CI=2.13-5.19) and Colorectal Adenoma (OR=2.47, 95% CI=1.49-4.08). There was no significant association between traditional pattern and the Colorectal Cancer (OR=99, 95% CI=0.61-1.59) and Colorectal Adenoma (OR=0.85, 95% CI=0.54-1.35) risk.

    Conclusion

    Our study suggested that the “Healthy” dietary pattern reduces the risk of Colorectal Cancer and Colorectal Adenoma, while the “Western” dietary pattern increases the risk of both Colorectal Cancer and Colorectal Adenoma.Keywords: Dietary pattern, Colorectal cancer, Colorectal adenoma, Healthy dietary pattern, Western dietary pattern.(Please cite as: Bahrami A, Houshyari M, Jafari S, Rafiei P, Mazandaranian MR, Hekmatdoost A, et al.

    Aim

    The aim of this study was to determine the relation between different food groups intake, nutritional status of cirrhotic patient and the stage of the disease.

    Background

    Protein-energy malnutrition (PEM) is a common problem in cirrhotic patients. Food intake assessment is highly important in the investigation regarding the health-disease process.

    Methods

    In this cross-sectional study, sixty eight ambulatory cirrhotic patients, with a mean age of 54 years, were included. In order to assess the stage of the disease and malnutrition status, Child-Pugh score and Subjective Global Assessment index were used respectively. Dietary intakes were assessed using a 168-item semi-quantitative validated food frequency questionnaire. Odds ratios (OR) and the corresponding 95% confidence intervals (CI) were computed, using logistic regression models.

    Results

    After adjustment for confounders, we found significant inverse relations between intakes of nuts (OR=0.140, CI=0.031-0.625) and olive (OR=0.212, CI=0.049-0.917) with severity of disease and boiled potatoes (OR=0.154, CI=0.040-0.592) and legumes (OR=0.090, CI=0.020-0.406) with malnutrition status. Inversely, solid fats (OR=3.324, CI=1.080-10.238) and mayonnaise (OR=5.215, CI=1.203-22.612) were positively associated with disease severity and malnutrition, respectively.

    Conclusion

    These findings suggest that selection of healthy foods was negatively associated with severity of hepatic cirrhosis whereas unhealthy food groups had a positive relation with disease severity and malnutrition.Keywords: food groups, hepatic cirrhosis, malnutrition, Child-Pugh score.(Please cite as: Pashayee-khamene F, Saber-firoozi M, Hatami B, Hekmatdoost A, Rashidkhani B, Aghamohammadi V, et al.

    Pancreatitis and pseudo-pancreatic cysts are frequently encountered entities; however, intrahepatic pseudocysts presenting as large number of liver cysts with absence of overt signs of pancreatitis has never been reported in literature. Here, we report an interesting case of multiple intrahepatic pancreatic pseudocysts (MIHPPs), a challenging diagnosis to be kept in mind while dealing with complex cystic lesions of liver. Pseudocysts are common complication of pancreatitis, often these are located within the vicinity of the pancreas in the lesser sac and the retroperitoneum. Extra pancreatic location of these cysts within the liver is a diagnosis often missed, with only 50 odd cases reported in literature till date. Most of these reported cases are either subcapsular in location or limited in number to one or two lesions. Although rare, possibility of MIHPPs is an important diagnosis that should be kept in mind while considering list of differentials for complex cystic lesions of the liver even in the absence of overt signs of pancreatitis.Keywords: pancreatitis, pseudocysts, hepatic cyst, intrahepatic pseudocysts, multidetector computed tomography.(Please cite as: Tomar S, Ghasi RG, Agarwal J.
