Context: Patients with inflammatory bowel disease (IBD) were found to have the higher intestinal expression of Angiotensin-Converting Enzyme2 (ACE2) that could consequently increase susceptibility to COVID-19 infection.Objective: This study reports the outcomes of COVID-19 infection in a large cohort of IBD patients. We compare levels of serum ACE and IFN-α between COVID19 patients with and without IBD. We performed a cross-sectional retrospective multicenter study.Methods: We enrolled patients with IBD screened for SARS-COV-2 in six medical centres in Iran from June to November 2020. The blood samples were drawn to measure COVID-19 IgM and IgG, and serum levels of sACE2, sACE1, and interferon-α, regardless of suspicious symptoms have done the molecular test.Results: A total of 534 IBD patients were included in the study. Of these, 109 (20.0%) cases had detectable IgG and IgM against SARS-CoV-2. sACE2 levels were higher in IBD patients than controls, whereas ACE1and IFN-α levels were similar among groups.
Irritable bowel syndrome (IBS) is a common disorder that affects the large intestine. Oxidative stress and inflammation play a major role in IBS. Considering the antioxidant properties of ellagic acid (EA), this study was designed to evaluate the effect of EA on oxidative stress index, inflammatory markers, and quality of life in patients with IBS. This research was conducted as a randomized, double-blind, placebo-controlled clinical trial; 44 patients with IBS were recruited. Patients who met the inclusion criteria were randomly allocated to consume a capsule containing 180 mg of EA per day (n = 22) or a placebo (n = 22) for 8 weeks. Serum levels of total antioxidant capacity (TAC), malondialdehyde (MDA), C-reactive protein (CRP), and interleukin-6 (IL-6) were measured at the beginning and the end of the study. Also, quality of life was assessed using a self-report questionnaire for IBS patients (IBS-QOL). At the end of the study, we saw a significant decrease and increase in the MDA and TAC in the intervention group, respectively (p < 0.05). Also, EA consumption reduced CRP and IL-6 levels, and these changes were significant in comparison with placebo group changes (p < 0.05). The overall score of IBS-QOL significantly decreased, and quality of life was increased (p < 0.05), but there were no significant changes in the placebo group. According to these findings, receiving polyphenols, such as EA, may help maintain intestinal health by modulating inflammation and oxidative stress and ultimately improving the quality of life in IBS patients.

BACKGROUND: The quality of sleep in people with irritable bowel syndrome (IBS) is reduced by increased oxidative stress and clinical problems. Assessing the effects of ellagic acid (EA) on sleep quality and gastrointestinal symptoms in patients with IBS was the aim of this study. METHODS: In this research that was conducted as a randomized, double-blind, placebo-controlled clinical trial, 44 patients with IBS were enlisted. Individuals approved by the project clinical counselor were divided into two intervention groups to receive 180 mg of EA per day (n = 22) and a placebo group (n = 22) for 2 months. Petersburg's Sleep Quality (PSQI) questionnaire and IBS severity score system (IBSSS) were assessed at the beginning and end of the study. Statistical analysis was performed using SPSS software. RESULTS: At the end of the study, changes in mean PSQI and scores related to sleep subgroups were significant between the two groups (P < .05). Also, the significant changes were not seen in sleep and sleep subgroups scores in the placebo group at the end of the study (P > .05). EA consumption reduced IBSSS score and IBS symptoms in the intervention group after 2 months (P < .05). DISCUSSION: The results arisen from this study indicated that receiving EA had a beneficial effect on sleep quality and gastrointestinal symptoms in IBS patients. The antioxidant and anti-inflammatory properties of EA may be responsible for these beneficial effects.

BACKGROUND & AIMS: Weight loss after proper diet is one of the main topics in nutrition. This study was designed to evaluate the effects of probiotic and alpha-Lipoic acid (ALA) supplements on the anthropometric indicators and maintenance of weight in overweight individuals. METHODS: This study consisted of two phases of weight loss (8 weeks) and weight maintenance (16 weeks). Eighty-eight overweight participants were randomly divided into 4 groups in phase 1: isocaloric diet with probiotic (500 mg), an isocaloric diet with ALA (600 mg) and probiotic, an isocaloric diet with ALA and isocaloric diet with placebo. In phase 2, participants received a normal diet with the mentioned supplements. In the beginning, end of the phase 1, and at the end of phase 2, weight, body mass index (BMI), waist circumference (WC), hip circumference (HC), body fat percentage, and blood pressure (BP) were measured. Also, 10 cc blood samples were taken from subjects to measure C-reactive protein (CRP). Data was analyzed using SPSS software. RESULTS: At the end of the two phases, the differences of changes in the probiotic + ALA group was significant in weight, WC, and CRP factors when compared to the other groups (P < 0.05). Also, at the end of the study, maintain a reduced weight was significantly higher in the probiotic + ALA group than in the other groups (P < 0.05). CONCLUSION: According to findings, probiotics and ALA supplementation with normal diet help to maintain decreased weight after adhering to a weight loss diet. This may be due to the reduction of inflammation. TRIAL REGISTRATION: (IRCT20141025019669N10).

Although colorectal cancer (CRC) is one of the most common cancers, the exact molecular mechanism of this cancer is not yet known. Circular RNAs (circRNAs), a class of non-coding RNAs, are newly identified and their role in the pathogenesis of various cancers has been shown. In this research, we studied the expression pattern and clinical importance of hsa_circ_000425 in CRC patients. After evaluation of hsa_circ_000425 expression rate in 4 CRC cell lines and 100 paired CRC tissues, the potential correlation between hsa_circ_000425 expression rate and clinicopathological parameters of CRC patients was analyzed. Additionally, receiver operating characteristic (ROC) curve was drawn to study the diagnostic value of hsa_circ_000425. A significant downregulation of hsa_circ_000425 was observed in both CRC tissues and cell lines. In addition, this downregulation was significantly associated with differentiation and lymphatic metastasis. The area under the ROC curve of hsa_circ_000425 was 0.839 (P < 0.001). hsa_circ_000425 may have a role in the pathogenesis of CRC and might act as a potential biomarker for the diagnosis and treatment of CRC; although further molecular studies must be performed in this regard.
BACKGROUND: Helicobacter pylori (H.pylori) infection causes multiple upper gastrointestinal diseases but optimal therapeutic regimen which can eradicate infection in all the cases has not yet been defined. This study was designed to evaluate the efficacy of triple levofloxacin-based versus clarithromycin-based therapy. METHODS: In this open-label randomized clinical trial study 120 patients who had esophagogastroduodenoscopy (EGD) with positive rapid urease test (RUT) were enrolled and divided into 2 groups. Case group was treated with levofloxacin (500 mg daily) plus amoxicillin (1 gr twice a day) plus omeprazole (20 mg daily) for 2 weeks. Control group was treated with clarithromycin (500 mg twice a day) plus omeprazole (20 mg daily) for 2 weeks. After the main course of treatment, they received maintenance treatment with omeprazole for 4 weeks. Stool antigen test was performed on them after two weeks of not having any medicine. RESULTS: H.pylori eradication (intention to treat analysis) was successful in 75% of case group and 51.7% of control group showing a significant difference (P=0.008). H.p infection eradication (per-protocol analysis) was successful in 80.4% in case group and 57.4%% in control group showing significant difference (P=0.009). Drugs adverse effects causing discontinuation treatment were seen in 5% of case group and 3.3% of control group which have not shown a significant difference between the two groups (P=0.648). CONCLUSION: Triple therapy with levofloxacin-based regimen has better efficacy than clarithromycin-based regimen and as safe as it is.
BACKGROUND: In order to detect nephropathy, measurement of total (24 hrs) urinary albumin or albumin/creatinin ratio in random urine samples is being recommended. But methods of albumin measurement are not available in all laboratories and also cost about 6 times more than that of urinary total protein measurement. OBJECTIVES: This Study was performed to determine appropriate cut off point in 24 hours urine total protein to diagnose micro- and macroalbuminuria in patients with diabetes mellitus. PATIENTS AND METHODS: In this study, 204 patients with diabetes mellitus type I and II were selected. In collected 24 hours urine from patients, protein and albumin were measured by using Pyrogallol and Immunoturbidimetry methods, respectively. RESULTS: Normoalbuminuri (albumin < 30 mg/24 hrs urine), microalbuminuri (albumin = 30-300 mg/24 hrs urine), and macroalbuminuri (albumin > 300 mg/24 hrs urine) were detected in 130, 51, and 23 patients, respectively. In 24 hrs urine collections, amounts of protein and albumin were compared to calculate cut off point of exerted protein for nephropathy diagnosis. cut off point of 73 mg/day for urinary total protein had appropriate sensitivity (94.5 %, CI = 91.4 % -97.6 %) and specificity (77.9 %, CI = 72.8 % -82.9 %) for microalbuminuria, while cut off point of 514 mg/day (sensitivity 95.7 %; specificity 98.9 %) was detected for diagnosis macroalbuminuria. Urine protein exertion of 150 mg/day that is currently considered as a normal value in most laboratory kits had a sensitivity of 73.1 % by which 30 % of microalbuminuric cases remained undiagnosed. CONCLUSIONS: Urinary total protein cut-off points of 73 mg/day and 514 mg/day were diagnostic for micro- and macroalbuminuria, respectively.
