Abstract
Disorders of gut-brain interaction are characterized by chronic gastrointestinal symptoms in the absence of abnormal endoscopic or radiologic findings or objective biomarkers that can be identified during routine clinical evaluation. The assessment of the symptom pattern and severity, therefore, is the key modality to evaluate the presence, impact, and evolution of these conditions, for both clinical and regulatory purposes. Patient-reported outcomes are structured symptom assessment questionnaires designed to evaluate symptom patterns, quantify severity of symptoms, and evaluate response to treatment at follow-up. This review provides an overview of currently available patient-reported outcomes for evaluating the main disorders of gut-brain interaction, specifically, functional dyspepsia; irritable bowel syndrome; and chronic constipation. It summarizes their content, level of validation for clinical practice and for research, and the regulatory approach to these conditions. Expected future developments and need for further research on patient-reported outcomes for these and other disorders of gut-brain interaction are highlighted.

Abstract
Norovirus is the second most common cause of diarrhea among solid organ transplant recipients. There are currently no approved therapies for Norovirus, which can substantially impact quality of life, particularly in an immunocompromised patient population. In order to establish clinical efficacy and support any medication claims related to a patient's symptoms or function, the Food and Drug Administration requires that a trial's primary endpoints be derived from patient reported outcome measures- an outcome that comes directly from the patient, without interpretation of the patient's response by a clinician or anyone else. In this paper, we describe our study team's approach to the definition, selection, measurement and evaluation of patient reported outcome measures as part of establishing clinical efficacy of Nitazoxanide for acute and chronic Norovirus in solid organ transplant recipients. We specifically describe our approach to measuring the primary efficacy endpoint- days to cessation of vomiting and diarrhea after randomization through 160 days, measured through daily symptom diaries as well as the impact of treatment on exploratory efficacy endpoints, particularly change in the impact of norovirus on psychological function and quality of life.

Abstract
OBJECTIVE To consolidate existing qualitative studies which examined the experiences and needs of adults living with IBS, and to gather a holistic insight for future directions and avenues to support these adults. METHODS A qualitative systematic review was conducted and six databases were searched for qualitative studies, beginning from each database's inception to July 2020. The qualitative data were meta-synthesised and thematic analysis was adopted. Any discrepancies that arose were discussed between the reviewers until a consensus was reached throughout the process of data screening, selection, critical appraisal and synthesis. RESULTS Seventeen studies with a total of 299 adults diagnosed with IBS were included. Four themes were identified: (1) physical, psychological, and social consequences; (2) impact of IBS on working adults; (3) dealing with IBS; and (4) sources of support and support needs. CONCLUSION Future research across geographically diverse locations are needed to gather a thorough perspective of the experiences and needs of adults living with IBS. The development and evaluation of technology-based, trained peer-led volunteers, and interventions that adopt mindfulness, active coping strategies, cognitive behavioural therapy and acceptance, and commitment therapy are needed. Ultimately, the collaboration between the relevant stakeholders is essential for standardised instruments and materials for accurate testing, diagnosis, assessment, treatment and management of IBS.

United European Gastroenterol J 2019; 7:1093-1101. [PMID: 31662866 PMCID: PMC6794699 DOI: 10.1177/2050640619862721] [Citation(s) in RCA: 29] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/29/2019] [Accepted: 06/18/2019] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND Irritable bowel syndrome (IBS) is highly prevalent and presents a clinical challenge. Gelsectan is a medical device containing xyloglucan (XG), pea protein and tannins (PPT) from grape seed extract, and xylo-oligosaccharides (XOS), which act together to protect and reinforce the intestinal barrier. OBJECTIVE The objective of this study is to evaluate the efficacy and safety of XG + PPT + XOS in patients with diarrhoea-predominant IBS (IBS-D). METHODS In this double-blind study, 60 patients were randomly assigned to receive XG + PPT + XOS or placebo for 28 days, then crossed over to the alternative treatment. Patients were followed for 60 days. RESULTS At Day 28, a significantly higher proportion of patients starting treatment with XG + PPT + XOS than placebo (87 vs 0%; p = 0.0019) presented normal stools (Bristol Stool Form Scale type 3-4). At Day 56, a significantly higher proportion of patients who crossed over to XG + PPT + XOS than placebo (93% vs 23%; p = 0.0001) presented normal stools. In the group allocated to receive XG + PPT + XOS after placebo, benefits of XG + PPT + XOS were maintained during follow-up. Subjective assessments of abdominal pain, bloating, quality of life and general health indicated significant improvement with XG + PPT + XOS over placebo. There were no related adverse events. CONCLUSION XG + PPT + XOS effectively controlled diarrhoea and alleviated clinical symptoms in patients with IBS-D, and was well tolerated.

Patient-reported outcome measures used in patients with primary sclerosing cholangitis: a systematic review. Health Qual Life Outcomes 2018; 16:133. [PMID: 29976215 PMCID: PMC6034220 DOI: 10.1186/s12955-018-0951-6] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2017] [Accepted: 06/04/2018] [Indexed: 02/08/2023] Open
Abstract
BACKGROUND Primary Sclerosing Cholangitis (PSC) is a rare chronic, cholestatic liver condition in which patients can experience a range of debilitating symptoms. Patient reported outcome measures (PROMs) could provide a valuable insight into the impact of PSC on patient quality of life and symptoms. A previous review has been conducted on the quality of life instruments used in liver transplant recipients. However, there has been no comprehensive review evaluating PROM use or measurement properties in PSC patients' to-date. The aim of the systematic review was to: (a) To identify and categorise which PROMs are currently being used in research involving the PSC population (b) To investigate the measurement properties of PROMs used in PSC. METHODS A systematic review of Medline, EMBASE and CINAHL, from inception to February 2018, was undertaken. The methodological quality of included studies was assessed using the Consensus-based Standards for selection of health Measurement Instruments (COSMIN) checklist. RESULTS Thirty-seven studies were identified, which included 36 different PROMs. Seven PROMs were generic, 10 disease-specific, 17 symptom-specific measures and 2 measures on dietary intake. The most common PROMs were the Short form-36 (SF-36) (n = 15) and Chronic liver disease questionnaire (CLDQ) (n = 6). Only three studies evaluated measurement properties, two studies evaluated the National Institute of Diabetes Digestive and Kidney Diseases Liver Transplant (NIDDK-QA) and one study evaluated the PSC PRO; however, according to the COSMIN guidelines, methodological quality was poor for the NIDDK-QA studies and fair for the PSC PRO study. CONCLUSION A wide variety of PROMs have been used to assess health-related quality of life and symptom burden in patients with PSC; however only two measures (NIDDK-QA and PSC PRO) have been formally validated in this population. The newly developed PSC PRO requires further validation in PSC patients with diverse demographics, comorbidities and at different stages of disease; however this is a promising new measure with which to assess the impact of PSC on patient quality of life and symptoms.

Abstract
Background This review aims to critically appraise and compare the measurement properties of inflammatory bowel disease (IBD)-specific health-related quality of life instruments. Methods Medline, EMBASE and ISI Web of Knowledge were searched from their inception to May 2016. IBD-specific instruments for patients with Crohn’s disease, ulcerative colitis or IBD were enrolled. The basic characteristics and domains of the instruments were collected. The methodological quality of measurement properties and measurement properties of the instruments were assessed. Results Fifteen IBD-specific instruments were included, which included twelve instruments for adult IBD patients and three for paediatric IBD patients. All of the instruments were developed in North American and European countries. The following common domains were identified: IBD-related symptoms, physical, emotional and social domain. The methodological quality was satisfactory for content validity; fair in internal consistency, reliability, structural validity, hypotheses testing and criterion validity; and poor in measurement error, cross-cultural validity and responsiveness. For adult IBD patients, the IBDQ-32 and its short version (SIBDQ) had good measurement properties and were the most widely used worldwide. For paediatric IBD patients, the IMPACT-III had good measurement properties and had more translated versions. Conclusions Most methodological quality should be promoted, especially measurement error, cross-cultural validity and responsiveness. The IBDQ-32 was the most widely used instrument with good reliability and validity, followed by the SIBDQ and IMPACT-III. Further validation studies are necessary to support the use of other instruments.

Abstract
BACKGROUND This masterclass introduces the topic of core outcome sets, describing rationale and methods for developing them, and providing some examples that are relevant for clinical research and practice. METHOD A core outcome set is a minimum consensus-based set of outcomes that should be measured and reported in all clinical trials for a specific health condition and/or intervention. Issues surrounding outcome assessment, such as selective reporting and inconsistency across studies, can be addressed by the development of a core set. As suggested by key initiatives in this field (i.e. OMERACT and COMET), the development requires achieving consensus on: (1) core outcome domains and (2) core outcome measurement instruments. Different methods can be used to reach consensus, including: literature systematic reviews to inform the process, qualitative research with clinicians and patients, group discussions (e.g. nominal group technique), and structured surveys (e.g. Delphi technique). Various stakeholders should be involved in the process, with particular attention to patients. RESULTS AND CONCLUSIONS Several COSs have been developed for musculoskeletal conditions including a longstanding one for low back pain, IMMPACT recommendations on outcomes for chronic pain, and OMERACT COSs for hip, knee and hand osteoarthritis. There is a lack of COSs for neurological, geriatric, cardio-respiratory and pediatric conditions, therefore, future research could determine the value of developing COSs for these conditions.
