Munjal, A, Dedania, B, Cash, BD
Expert opinion on pharmacotherapy. 2020;(1):63-71
Abstract
Introduction: Irritable bowel syndrome with diarrhea (IBS-D) is among the most common functional gastrointestinal (GI) disorders and is associated with impaired quality of life, increased health-care utilization, and significant costs to patients and society. The treatment of IBS is typically hierarchal with initial therapies consisting of dietary and lifestyle modifications. Pharmacotherapy with over-the-counter and prescription medications is also commonly used for symptomatic control in the course of therapy.Areas covered: Three medications are approved by the United States Food and Drug Administration (FDA) for IBS-D, with all of them demonstrating efficacy in randomized, placebo-controlled trials. In this review, the authors discuss the clinical trial data applicable to the current FDA approved IBS-D therapies as well as review data related to new and emerging therapies for this condition.Expert opinion: Clinicians should be familiar with emerging therapies for IBS-D as they may provide benefit to some IBS-D patients. The exact mechanisms of action of many of the emerging agents for IBS-D remain unknown. Despite substantial differences and limitations in the design and quality of supporting studies, there is an increasing body of evidence suggesting that emerging agents may promote meaningful symptom improvement in patients with IBS-D.

Abstract
BACKGROUND Probiotics can be used for the treatment of viral gastroenteritis. OBJECTIVE This systematic review is to evaluate the evidence regarding the effect of probiotics on human cases of viral gastroenteritis. METHODS The objective of this review is to evaluate the effectiveness of probiotics against placebo or standard treatment for viral gastroenteritis. A comprehensive search of Cochrane Library, EMBASE, MEDLINE via PubMed and Ovid databases, and unpublished studies (till 27 January 2018) was conducted followed by a process of study selection and critical appraisal by two independent reviewers. Randomized controlled trials assessing probiotic administration in human subjects infected with any species of gastroenteritis viruses were considered for inclusion. Only studies with a confirmed viral cause of infection were included. This study was developed using the JBI methodology for systematic reviews, which is in accordance with the PRISMA guideline. Meta-analysis was conducted where feasible. Data were pooled using the inverse variance method with random effects models and expressed as Mean Differences (MDs) with 95% Confidence Intervals (CIs). Heterogeneity was assessed by Cochran Q statistic and quantified by the I2 statistic. We included 17 RCTs, containing 3,082 patients. RESULTS Probiotics can improve symptoms of viral gastroenteritis, including the duration of diarrhea (mean difference 0.7 days, 95% CI 0.31 to 1.09 days, n = 740, ten trials) and duration of hospitalization (mean difference 0.76 days, 95% CI 0.61 to 0.92 days, n = 329, four trials). CONCLUSION The results of this review show that the administration of probiotics in patients with viral gastroenteritis should be considered.

Nutrients. 2020;(1)
Abstract
(1) Background: Nutritional status can influence the quality of life (QoL) of cancer patients. (2) Methods: This subanalysis evaluated the impact of an oral oligomeric enteral nutrition (OEN) protocol on the QoL of patients with oncology treatment-related diarrhea (OTRD) in a multicenter, observational, prospective study (DIAPOENO study). QoL was assessed with the Nottingham Health Profile (NHP) at baseline and after eight weeks of OEN treatment. (3) In the overall population, all the NHP categories significantly improved after eight weeks of OEN treatment: energy levels (p < 0.001), pain (p < 0.001), emotional reactions (p < 0.001), sleep (p < 0.001), social isolation (p = 0.023), and physical abilities (p = 0.001). QoL improvement was higher in patients with improved or maintained nutritional status and in those with improved consistency of stools with the OEN protocol. However, QoL did not significantly improve in patients with worse nutritional status and with worse or maintained stool consistency with the OEN protocol. QoL improved regardless of disease severity. Multivariate logistic regression analysis showed that weight change was significantly associated with improved QoL (OR 2.90-5.3), except for social isolation, in models unadjusted and adjusted to age, sex, oncology treatment, and stool consistency. (4) Conclusion: In this subanalysis, the OEN protocol was associated with improved QoL.

Abstract
This retrospective study aimed to explore the benefits and safety of probiotics (live combined Bacillus subtilis and Enterococcus faecium granules with multivitamines) for the treatment of children with antibiotic-associated diarrhea (AAD).A total of 72 children with AAD were analyzed in this study. Of these, 36 children received routine treatment plus probiotics, and were assigned to a treatment group. The other 36 children underwent routine treatment alone, and were assigned to a control group. Patients in both groups were treated for a total of 7 days. The efficacy and safety were evaluated by duration of diarrhea (days), number of dressings needed daily, abdominal pain intensity, stool consistency (as assessed by Bristol Stool Scale (BSS)), and any adverse events.After treatment, probiotics showed encouraging benefits in decreasing duration of diarrhea (days) (P < .01), number of dressings needed every day (P < .01), abdominal pain intensity (P < .01), and stool consistency (BSS (3-5), P < .01; BSS (6-7), P < .01). In addition, no adverse events were documented in this study.The findings of this study demonstrated that probiotics may provide promising benefit for children with AAD. Further studies are still needed to warrant theses findings.

Abstract
OBJECTIVES This study aimed to evaluate whether vitamin D deficiency is associated with the severity of symptoms of irritable bowel syndrome (IBS) patients. Stress and gut inflammation can increase the serum level of corticotropin-releasing hormone (CRH) and interleukin-6 (IL-6), leading to a change in bowel movements. The aim of this study was to evaluate the anti-inflammatory and psychological effects of vitamin D3 supplementation on the symptom improvement of patients with a diarrhea-predominant form of IBS (IBS-D). METHODS Eighty-eight IBS-D patients (age: 18-65 years) based on Rome IV criteria who suffered from vitamin D deficiency and/or insufficiency were enrolled in this randomized, placebo-controlled trial from February 2017 to May 2018 at Rasoul-e-Akram Hospital, Tehran, Iran. Participants were randomly divided into two groups. The intervention group received 50,000 IU vitamin D3 weekly and the control group received a placebo for 9 weeks. All patients received Mebeverine 135 mg twice a day besides supplementation. The IBS Severity Score System (IBS-SSS), serum 25(OH) vitamin D3, CRH, and IL-6 were measured before and after interventions. RESULTS Seventy-four patients completed the study. The severity of IBS symptoms (p < 0.01) and IL-6 (p = 0.02) decreased significantly in the intervention group as compared to the control group, but there was no significant difference in the serum level of CRH. Also, in the treatment group, IBS-SSS and IL-6 were significantly reduced at the end of the study from baseline (p < 0.01 and p < 0.03, respectively). CONCLUSION Our findings indicate that vitamin D3 supplementation can modulate the serum level of CRH and IL-6 and can improve symptoms in IBS-D patients. Vitamin D3 supplementation should be considered in IBS-D patients who suffer from vitamin D deficiency and/or insufficiency.

Mahmud, MA, Spigt, M, Bezabih, AM, Dinant, GJ, Velasco, RB
BMC research notes. 2020;(1):1
Abstract
OBJECTIVE In marginalized setting, under-nutrition and illnesses due to infectious agents create a vicious circle. In our previous study, we reported that easy-to-do hand hygiene interventions were effective in preventing intestinal parasite infections (IPIs) and reduce the rate of anaemia among school-aged children. The aim of this study was to assess the pattern of associations between IPIs, anaemia and diarrhoea among the school-aged children and to explore if the observed impact of hand-washing and nail clipping interventions in our findings was similar across children with different baseline demographic and disease characteristics. The study was based on the analysis of data that was collected during the randomized controlled trial and hence have used the same study participants and study area. RESULTS Children with IPIs had a much higher chance of also being anaemic (AOR 2.09, 95% CI 1.15-3.80), having diarrhoea (AOR 2.83, 95% CI 1.57-5.09), and vice versa. Anaemia and diarrhoea were very strongly related (AOR 9.62, 95% CI 5.18-17.85). Overall, hand-washing with soap at key times and weekly nail clipping were efficacious in preventing intestinal parasite re-infection among children despite the differences in baseline demographic characteristics. TRIAL REGISTRATION NCT01619254 (June 09/2012).

Scientific reports. 2020;(1):6344
Abstract
The acute diarrhea is a wide-spread disease. The prescription of enterosorbents is appropriate as a primary measure for the treatment of the acute diarrhea for effective prevention of the fluid and electrolyte loss, as well as method for symptom relief of the attack of the disease. Aim of the study - the antidiarrheal efficacy and safety study of high-dispersion silicon dioxide enterosorbent in tablet dosage form in patients with acute diarrhea. This was randomized, double-blind, placebo-controlled, 4-center study. Acute diarrhea was defined as three and more episodes of watery stool per day either during 48 hours or less before study entry in the patients having normal stool recently. It has been postulated that symptoms and signs of acute diarrhea have to be caused by direct infection of the gastrointestinal tract and did not associated with moderate-to-severe systemic states. 144 patients with established acute diarrhea were randomized into treatment group (enterosorbent "Carbowhite", n = 120) or placebo group. Date collection including severity diarrhea, systemic symptoms was performed at baseline and daily during 7 days. Stool examination and serological assay were performed at baseline. The primary end points were declared as time to complete recovery from acute diarrhea. It has been found that the use of the siliceous enterosorbent ("Carbowhite") allowed to reduce (p < 0.001) the treatment period averagely for 0.9 days (95% confidence interval 0.5-1.2 days) in comparison with placebo. Data of safety monitoring has revealed that both patient groups had negative stool culture, while initiation of antibiotic treatment was run more frequently in placebo group (8.3%) compared to investigational product group (4.1%, P = 0.044). The siliceous enterosorbent "Carbowhite" was well tolerated and reduced the recovery time of the acute episode of the diarrhea in the clinically significant form.

Use of Fecal Occult Blood Testing as a Diagnostic Tool for Clinical Indications: A Systematic Review and Meta-Analysis.
Lee, MW, Pourmorady, JS, Laine, L
The American journal of gastroenterology. 2020;(5):662-670
Abstract
INTRODUCTION Fecal occult blood tests (FOBTs) are validated only for colorectal cancer (CRC) screening, but are commonly used as a diagnostic test in other clinical settings. We performed a systematic review to assess performance characteristics of FOBT as a diagnostic test for clinical indications. METHODS Bibliographic databases were searched to identify studies in adult patients with a specific gastrointestinal symptom or condition who underwent FOBT and a reference test and provided data on diagnoses. Our primary end point was sensitivity. Risk of bias was assessed with the QUADAS-2 tool. RESULTS Twenty-two studies met the inclusion criteria: 12 in iron deficiency anemia (IDA) (5 fecal immunochemical (FIT) and 7 guaiac based), 8 in ulcerative colitis (FIT), and 2 in acute diarrhea (guaiac based). Only 2 studies had low risk of bias on all domains of the QUADAS-2. On meta-analysis, FOBT had a sensitivity of 0.58 (95% confidence interval [CI] 0.53-0.63) and a specificity of 0.84 (95% CI 0.75-0.89) in predicting presumptive causes of IDA at endoscopy, with comparable results for guaiac-based tests and FIT. Sensitivity was higher for CRC (0.83) than non-CRC lesions (0.54). FIT had a sensitivity of 0.72 (95% CI 0.57-0.84) and a specificity of 0.80 (95% CI 0.67-0.89) in predicting endoscopic activity in UC. Sensitivities of FOBT for positive stool culture in acute diarrhea were 0.38 and 0.87. DISCUSSION Sensitivity of FOBT is poor for IDA: 42% of patients with identifiable causes of IDA had false-negative FOBT. Our results did not show acceptable performance characteristics for FOBT to guide decisions regarding endoscopic evaluation and do not support its use in IDA.
