Some patients' HRQoL improved with evidence-based standard therapy. Others, particularly those with severe and refractory CP, often required conversion to or addition of experimental noninvasive (e.g., ondansetron) or extracorporeal liver support to alleviate CP. In addition, studies investigating a newer class drug, the ileal bile acid transporter inhibitor (IBATi), demonstrate its effectiveness in reducing serum bile acid and alleviating CP with sustained improvement noted in patients with the inherited childhood cholestatic disorders - progressive familial intrahepatic cholestasis and Alagille syndrome.</p><p><strong>Conclusion: </strong>Our findings consolidate data on the efficacy of guideline-based approaches and newer therapies for CP. While the initial findings are promising, additional clinical trials will be needed to determine the full extent of IBATi's efficacy and potential use in treating other common CLDs.

Given the child's developing immune system, the impact of COVID-19 on disease development may differ compared to adults. This study reviews the potential bi-directional relationship between COVID-19 and GI diseases in children, focusing on common pediatric conditions such as functional GI disorders (FGID), celiac disease (CeD), and inflammatory bowel disease (IBD).

In adults, a global consensus by the experts in the field concluded that <i>H. pylori</i> gastritis is an infectious disease and requires treatment irrespective of the presence or absence of symptoms due to the potential for serious complication like peptic ulcer disease and gastric neoplasia. However, although more than half the world's population harbors <i>H. pylori</i>, these serious complications occur only in a small minority of the infected population, even less so in childhood. More importantly, there is accumulating evidence for beneficial role of <i>H. pylori</i> against many chronic health conditions, from several epidemiological and laboratory studies. No doubt, eradication therapy is indicated in children with <i>H. pylori-</i>related peptic ulcer disease. Even though the pediatric guidelines from various learned societies recommend against a \"test and treat\" strategy, this is not always adhered to. With the accumulating evidence of the possible beneficial role of <i>H. pylori</i>, it is time to pause and think, are we causing more harm than good by eradicating <i>H. pylori</i> in every child who has this bug?</p>","PeriodicalId":23022,"journal":{"name":"Therapeutic Advances in Gastroenterology","volume":"16 ","pages":"17562848231177610"},"PeriodicalIF":4.2,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/93/bd/10.1177_17562848231177610.PMC10285598.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10074746","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
