BACKGROUND The anti-TNF drugs are shown to be highly effective in treatment of patients with moderate-tosevere inflammatory bowel disease (IBD). Here, we aimed to assess the efficacy and safety of anti- TNF therapy at the national level. METHODS IBD patients aged 15 > years who received Infliximab and/or CinnoRA® between 2013 to July 2018 were identified. The data extracted from medical dossier and telephonic interview. The efficacy of therapy was defined as time to drug discontinuation or need for IBD-related surgery. The safety was assessed based on patient's reported adverse events. RESULTS We included 315 patients. The mean age of patients was 37.2 years and 62.2% of them developed the disease before age 30 years. Involvement of masculoskeletal system was reported in 7.3% of patients. Partial and complete response to Anti-TNF therapy was seen in 67% of patients. About 16% of patients did not respond to induction therapy and 16.9% of patients lost their response to Anti-TNF during one year. No serious adverse events, serious opportunistic infection, tuberculosis and malignancies reported by patients. Two patients reported pneumonia. CONCLUSION This study for the first time in our country, provides the evidences for efficacy of anti-TNF therapy in moderate to severe IBD patients. [ABSTRACT FROM AUTHOR]

BACKGROUND Currently, it has been demonstrated that gastroesophageal reflux disease (GERD) is one of the most important disorders of the digestive system and the commixture of regular diet has a significant influence on its incidence, symptoms, and prognosis. The purpose of this study was to evaluate the effect of zinc supplementation, in combination with PPIs(Proton pump inhibitors), on the improvement of GERD symptoms. METHODS In a randomized double blind clinical trial, patients with reflux symptoms, who had obtained Reflux Disease Questionnaire (RDQ) score more than 8, were included and all the demographic features were recorded. Then, using upper gastrointestinal (GI) endoscopy, all the patientswere divided into two groups as having non-erosive reflux disorder (NERD),or erosive reflux disorder (ERD). At the next step, based on random block statistical method, we divided the two groups into two subgroups; the drug subgroup [treated with PPIs (40 mg pantoprazole/daily), changing life style, and 220 mg zinc capsules daily] and the placebo subgroup [treated with PPIs, changing life style, and placebo]. After 3 months, we analyzed all data and the RDQ questionnaire was filled out for each patient. This project has been registered in Iranian Registry of Clinical Trials (IRCT) and all data were analyzed using SPSS software version 2. RESULTS A total of 140 patients (81 women and 59 men) with mean age of 42.78±11.5 years were included with 70 patients in each group. The most frequent presentations were heart burn (45.7%), and acid regurgitation (39.3%). The RDQ scores decreased after intervention in both drug (p<0.001) and placebo groups (p<0.001), which were statistically significant. But the difference of RDQ scores between the drug group and placebo group was not statistically significant (p=0.086). CONCLUSION Zinc supplementation cannot improve the severity of GERD.

BACKGROUND The geographical incidence of IBD varies considerably. This study aimed to survey the epidemiologic features of IBD in Guilan province, North of Iran, during ten years duration. METHODS In this retrospective cross-sectional study, we assessed the documents of 868 patients with IBD referred to private and governmental clinics of Guilan province between 2002 and 2012. Variables such as demographic data, risk factors, diagnosis, extraintestinal manifestations and type of treatment were collected. RESULTS Among 868 patients with IBD, 756 patients (87.1%) diagnosed as UC and 112 patients (12.9%) as CD. The mean age of patients with UC and CD was 46.73±15.79 and 40.15±14.27 years respectively. Male/female ratio in UC and CD was 0.92:1 and 0.75:1 respectively. The most common age of disease initiation in UC was 40-59 years and in CD 20-39 years (p<0.001). Extraintestinal manifestations were seen in 25.4 percent of patients with IBD. Most of patients were treated with combination of two drugs: salicylates and azathioprine (p<0.04). The incidence of IBD gradually increased during the past 4 years in Guilan province. CONCLUSION This study showed that CD were presented significantly more common in younger patients than UC and totally the disease was slightly more common in female. [ABSTRACT FROM AUTHOR]
