The esophagus is involved in up to 80% of the cases and represents a major cause of serious morbidities that deeply impact on the quality of life and survival of patients. Indeed, the presence of esophageal dysfunction is a good prognostic indicator in SSc, primarily due to its impact on pulmonary disease. Thus, the detection of esophageal motility alterations plays a critical role to prevent the development of both esophageal and pulmonary complications and to improve the survival of these patients. Currently, this diagnostic work‐up has been limited to the use of esophageal manometry, which is considered the gold standard for the evaluation of motor physiology and pathophysiology of this organ in different clinical situations. However, in recent years, new equipments such as high‐resolution (−impedance) manometry and functional luminal imaging probe have been developed and used in many esophageal clinical settings, including SSc. In this mini‐review, we summarize current evidence regarding esophageal dysmotility, in the light of new data on secondary peristalsis published in this issue of the journal.","PeriodicalId":19104,"journal":{"name":"Neurogastroenterology & Motility","volume":"193 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75874539","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Letter in response to Black et al. (2020): Authors’ Reply","authors":"C. Black, A. Ford","doi":"10.1111/nmo.14388","DOIUrl":"https://doi.org/10.1111/nmo.14388","url":null,"abstract":"To the editor; We are grateful to Trindade et al. 1 for their interest in our paper, which examined the factor structure of the visceral sensitivity index (VSI) among 811 individuals with Rome IV irritable bowel syndrome (IBS) from the UK.2 The VSI is a measure of gastrointestinal symptomspecific anxiety that had not been validated in the UK population. The original validation study from the USA reported an unifactorial structure,3 whereas our analysis identified three separate factors. Moreover, we found no evidence that VSI mediated the relationship between measures of generalized anxiety and symptom severity in IBS. In their analysis of 424 Swedish patients with IBS, Trindade et al. report a singlefactor structure in agreement with the original VSI study.1 They discuss that cultural and linguistic differences between studies may have influenced the responses to the VSI, but this seems unlikely. The original VSI was developed in English, and while differences in spelling and usage exist between the UK and the USA, there is nothing that should affect understanding of the VSI in the UK population. Whether Trindade et al. translated the VSI into Swedish is unclear. However, this is unlikely to explain the differences between their results and ours, given the similarity between their findings and those from the USA. The cultural concepts discussed in the VSI, such as eating out in restaurants, will be familiar to people from any Westernized society. Consequently, methodological differences between the studies are likely to be of greater relevance to understanding the contrasting results. The original validation study involved only 96 individuals who selfidentified with IBS, of whom 85% met Rome II criteria.3 We also recruited individuals who selfidentified with IBS, but our study cohort was much larger, and we only included those who met diagnostic criteria for IBS. Moreover, we defined IBS using the current Rome IV criteria.4 These are more specific for diagnosing IBS compared with previous iterations,5,6 but they also select for patients who have more severe symptoms and greater psychological comorbidity.7,8 This may explain why analysis of the VSI in our study yielded a different factor structure than was originally described. Trindade et al. recruited patients referred to a tertiary center among whom reporting gastrointestinal symptomspecific anxiety may conceivably be more homogeneous. Furthermore, it is unclear how they defined IBS in their study. Importantly, their results are not fully published, limiting comparison with our study; however, we agree that further work to validate and refine the VSI is warranted.","PeriodicalId":19104,"journal":{"name":"Neurogastroenterology & Motility","volume":"38 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85343174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Keefer","doi":"10.1111/nmo.14373","DOIUrl":"https://doi.org/10.1111/nmo.14373","url":null,"abstract":"Functional esophageal disorders (functional chest pain, functional heartburn, reflux hypersensitivity, globus, and functional dysphagia) are the disorders of gut‐brain interactions (DGBI) and present with esophageal symptoms not associated with a structural, major motility or underlying inflammatory condition. Notably, many patients with the latter conditions may still experience esophageal symptoms beyond what could be attributed to their underlying disorders. Esophageal visceral hypersensitivity and hypervigilance are the two pathways which drive functional esophageal disorders and symptoms. These functional esophageal symptoms may be severe, leaving patients with impaired quality of life and inadequate treatment outcomes. Neuromodulators are the foundation of the pharmacologic approach of many of the functional esophageal disorders and symptoms, modulating both peripheral and central hyperalgesia. There is also emerging evidence for brain‐gut behavioral therapies (BGBT) such as gut‐directed hypnotherapy and cognitive behavior therapy for the treatment of a variety of DGBIs. In this issue of Neurogastroenterology and Motility, Hurtte et al. add to the literature on the effectiveness of BGBT in treating functional esophageal symptoms, showing multimodal therapy with pharmacologic and non‐pharmacologic approaches led to improvement in health‐related quality of life. In this review, we outline the mechanistic underpinnings of BGBT and review the existing evidence for BGBT for functional esophageal disorders and symptoms. We also highlight the future research directions and challenges for scaling these therapies.","PeriodicalId":19104,"journal":{"name":"Neurogastroenterology & Motility","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89643969","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
