Although having a common global pathophysiological mechanism, IBD patients are characterized by a significant interindividual heterogeneity and may differ by their disease type, disease locations, disease behaviours, disease manifestations, disease course as well as treatment needs. Indeed, although the therapeutic armamentarium for these diseases has expanded rapidly in recent years, a proportion of patients remains with a suboptimal response to medical treatment due to primary non-response, secondary loss of response or intolerance to currently available drugs. Identifying, prior to treatment initiation, which patients are likely to respond to a specific drug would improve the disease management, avoid unnecessary side effects and reduce the healthcare expenses. Precision medicine classifies individuals into subpopulations according to clinical and molecular characteristics with the objective to tailor preventative and therapeutic interventions to the characteristics of each patient. Interventions would thus be performed only on those who will benefit, sparing side effects and expense for those who will not. This review aims to summarize clinical factors, biomarkers (genetic, transcriptomic, proteomic, metabolic, radiomic or from the microbiota) and tools that could predict disease progression to guide towards a step-up or top-down strategy. Predictive factors of response or non-response to treatment will then be reviewed, followed by a discussion about the optimal dose of drug required for patients. The time at which these treatments should be administered (or rather can be stopped in case of a deep remission or in the aftermath of a surgery) will also be addressed. IBD remain biologically complex, with multifactorial etiopathology, clinical heterogeneity as well as temporal and therapeutic variabilities, which makes precision medicine especially challenging in this area.

Clinical remission was defined as Harvey-Bradshaw index ⩽ 4 and biological remission as a faecal calprotectin (FC) &lt;250 mg/g and C-reactive protein (CRP) &lt;5 mg/L. Moreover, the persistence of the treatment and any adverse events were assessed.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;In all, 84 patients were included in the study, males and females were equally distributed, with a median age of 63 years [interquartile range (IQR): 51-75] and a median disease duration of 6.8 years [IQR: 3.6-17.0]. The majority (86.9%) of patients were treated with ustekinumab as monotherapy, without concomitant immunosuppressive medication. The proportion of patients in corticosteroid-free clinical remission or response at weeks 16, 24, 52 and 72 was 93.3% (56/60), 86.8% (46/53), 82.2% (37/45) and 71.4% (30/42), respectively.

Four publications on studies of IF in IBD were found: three randomized controlled trials in animal models of colitis and one prospective observational study in patients with IBD. The results from animal studies suggest either moderate or no changes in weight but improvements in colitis with IF. These improvements may be mediated through changes in the gut microbiome, decreased oxidative stress and increased colonic short-chain fatty acids. The study in humans was small and uncontrolled, and it did not assess changes in weight, making it difficult to draw conclusions around the effects of IF on changes in weight or disease course. Given that preclinical evidence suggests intermittent fasting may play a beneficial role in IBD, randomized controlled trials in large patients with active disease are warranted to determine whether intermittent fasting could be an integrated therapy for patients with IBD management, either for weight or for disease management. These studies should also explore the potential mechanisms of action related to intermittent fasting.</p>","PeriodicalId":23022,"journal":{"name":"Therapeutic Advances in Gastroenterology","volume":"16 ","pages":"17562848231171756"},"PeriodicalIF":4.2,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10240551/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9583608","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}

There was a delay in organ procurement that led to a decrease in the number of liver transplants (LTs) and an increase in the morality of waitlisted patients at the beginning of the pandemic. LT numbers later equalized to pre-pandemic numbers due to combined efforts and adaptability of transplant centers as well as dynamic guidelines. Due to being immunosuppressed, the demographics of LT patients were at an increased risk of infection. Although there is a higher rate of mortality and morbidity in patients with chronic liver disease, LT itself is not a risk factor for mortality in COVID-19. There was no difference in overall mortality in LT patients compared to non-LT patients, and mortality risk factors were the same: age, hypertension, diabetes, obesity, and chronic kidney disease. The most common causes of death were respiratory complications. Liver-related deaths were reported in 1.6% of patients. The optimal timing of liver transplantation post-infection depends on various factors, such as the severity of liver injury, the presence of comorbidities, and the progression of the underlying liver disease. There is not enough data available on COVID-19 cholangiopathy and the number of cases that will be seen in the future that will require LT. There are some concerns of lower immunogenicity of COVID-19 vaccines in LT patients but available evidence suggests that the vaccines are safe and well-tolerated.</p>","PeriodicalId":23022,"journal":{"name":"Therapeutic Advances in Gastroenterology","volume":"16 ","pages":"17562848231171452"},"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/62/e7/10.1177_17562848231171452.PMC10172841.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9467639","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}
