Abstract
BACKGROUND AND AIMS Randomised controlled trials historically under-represent marginalised racial and ethnic populations. As incidence and prevalence of Crohn's disease in these groups rise, it is important to characterise their inclusion in randomised controlled trials on first-line and pipe-line medications. METHODS PubMed was searched systematically for randomised controlled trials of biologic and small molecule inhibitor [SMI] medications, with a primary outcome related to efficacy following PRISMA guidelines. We used descriptive statistics to summarise demographic variables and meta-regression analyses to estimate temporal trends in racial inclusion. RESULTS More than a half of trials did not report any racial/ethnic demographics [53.7%] and several reported racial demographics for only one race [20.9%]. When racial data were reported, Whites made up 90.2% of participants. Percentages of Black, Asian, Native American/Pacific Islander, and participants considered 'Other' averaged 2.9%, 11.6%, 0.5%, and 1.6% out of the total sample sizes of 3901, 3742, 828 and 4027, respectively. Proportional representation of White participants decreased over time [p <0.01] and proportional representation of Asian participants increased over time [p = 0.047]. In ordinal logistic regression, mean year of trial enrolment significantly increased the number of racial groups reported [p <0.001]. CONCLUSIONS Half of published randomised controlled trials in Crohn's disease contain no racial or ethnic demographics, and the remaining often only have limited inclusion of Black, Native American/Pacific Islander, and Hispanic patients. Further work should characterise representation in observational and prospective trials. Researchers should work to: 1] increase reporting of racial and ethnic demographics; and 2] improve recruitment and retention of marginalised populations.

Gong S, Zhang Y, Wang Y, Yang X, Cheng B, Song Z, Liu X. Study on the burden of digestive diseases among Chinese residents in the 21st century. Front Public Health 2024; 11:1314122. [PMID: 38269386 PMCID: PMC10806247 DOI: 10.3389/fpubh.2023.1314122] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2023] [Accepted: 12/18/2023] [Indexed: 01/26/2024] Open
Abstract
Background The global burden of digestive diseases has increased in recent years. The study aims to comprehend the trend of incidence and death rates related to digestive diseases in China from 2000 to 2020. Methods The study collected data on digestive diseases and their causes, such as incidence rates, death rates, Years of Life Lost, Years Lived with Disability, Disability-Adjusted Life Years and estimated annual percentage change from the 2019 Global Burden of Disease website and the Chinese Health and Wellness Statistical Yearbook spanning. And we employed the age-period-cohort model to analyze the influence of age, period, and birth cohort on the trend of death rates associated with digestive diseases. Results In contrast to the global burden of digestive disease, China experienced increases in the age-standardized incidence for inflammatory bowel disease, gallbladder and biliary diseases, as well as appendicitis from 2000 to 2019. The corresponding estimated annual percentage change for these diseases were 2.06, 1.74, and 0.99. Females showed a significantly higher incidence of digestive diseases, while males experienced a higher death rate. Moreover, individuals in the age groups under 5 years and over 60 years exhibited higher death rates than those in other age groups. Conclusion The findings underscore the ongoing importance of digestive diseases as a substantial public health issue in China. Reducing the disease burden of IBD in China necessitates healthcare systems to enhance their infrastructure and personnel readiness, ensuring an equitable, affordable, and accessible distribution of care for IBD patients. To reduce the occurrence and mortality rates of digestive diseases in China, the government should promote the adoption of early screening policies for individuals under the 5 year and those above the 60 year. These policies should be accompanied by customized preventive measures.

Abstract
BACKGROUND This study aims to evaluate the long-term trend of prevalence and DALY (disability-adjusted life-year) rate on the age, period and cohort (APC) of the BRICS (Brazil, Russia, India, China and South Africa) country for autoimmune diseases (rheumatoid arthritis (RA), inflammatory bowel disease (IBD), multiple sclerosis (MS) and psoriasis). METHODS The data are sourced from the Global Burden of Disease Study 2019, and it uses the Joinpoint regression model to estimate the time trends of autoimmune diseases from 1990 to 2019. Additionally, it employs the Age-Period-Cohort (APC) model to estimate the age, period, and cohort effects from 1990 to 2019. RESULTS For 1990 to 2019, the ASPR (age-standardised prevalence rate) of IBD increased significantly for China and South Africa, and decreased significantly for Brazil, India, Russian. The Russian ASPR of MS demonstrated a significantly decreasing trend (average annual percent change=-0.5%, 95% CI -0.6 to -0.5), with the most increased occurring in Brazil at 2009-2014. The cohort effect on DALY rates for Psoriasis displayed an ongoing decreasing trend from the 1929-1933 birth cohort to the 1999-2003 birth cohort. Specifically, the five countries relative risk values (RRs) of DALYs due to RA increased significantly by 7.98, 16.07, 5.98, 3.19, 9.13 times, from 20 to 24 age group to 65 to 69 age group. CONCLUSIONS The population of the BRICS countries accounts for more than 40% of the global population. And we found that the age effect of various autoimmune diseases is heavily influenced by population ageing.

Clin Gastroenterol Hepatol 2023; 21:3379-3386.e29. [PMID: 37660767 DOI: 10.1016/j.cgh.2023.08.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/06/2022] [Revised: 07/25/2023] [Accepted: 08/07/2023] [Indexed: 09/05/2023]
Abstract
BACKGROUND & AIMS Limited studies have evaluated the burden of inflammatory bowel disease (IBD) in China. We aimed to estimate the incidence of IBD including ulcerative colitis (UC) and Crohn's disease (CD) in urban China. METHODS The national urban incidence in 2016 was calculated based on urban basic medical insurance from 2012 to 2016 in China by using a 4-year washout period. The incidence in Yinzhou District estimated from the Yinzhou electronic health care record database was used to test the accuracy of the results from insurance data. RESULTS A total of 95,555 patients with IBD were identified. The incidence in 2016 was 10.04 (95% confidence interval, 6.95-13.71) per 100,000 person-years. The incidence rates of both UC and CD were higher among males than among females. There was a sharp increase in UC incidence before the age of 30 years and stabilization in later years (50-79 years old), whereas CD incidence peaked at 30 to 34 years old and experienced decline subsequently. The incidence of UC was much greater than that of CD, with a UC-to-CD incidence ratio of 12.61. The results from the Yinzhou database confirmed these results. CONCLUSIONS This study is the first to draw a portrait of the distribution of IBD in urban China. The difference in IBD incidence between urban China and other countries suggests an association between the IBD burden and industrialization process. The accelerating urbanization and industrialization process in China, a country with a population of 1.4 billion people, will likely increase the burden of IBD.

Abstract
Crohn's disease (CD) is a recurrent, chronic inflammatory condition of the gastrointestinal tract which is a clinical subtype of inflammatory bowel disease for which timely and non-invasive diagnosis in children remains a challenge. A novel predictive risk signature for pediatric CD diagnosis was constructed from bioinformatics analysis of six mRNAs, adenomatosis polyposis downregulated 1 (APCDD1), complement component 1r, mitogen-activated protein kinase kinase kinase kinase 5 (MAP3K5), lysophosphatidylcholine acyltransferase 1, sphingomyelin synthase 1 and transmembrane protein 184B, and validated using samples. Statistical evaluation was performed by support vector machine learning, weighted gene co-expression network analysis, differentially expressed genes and pathological assessment. Hematoxylin-eosin staining and immunohistochemistry results showed that APCDD1 was highly expressed in pediatric CD tissues. Evaluation by decision curve analysis and area under the curve indicated good predictive efficacy. Gene Ontology, Kyoto Encyclopedia of Genes and Genomes and gene set enrichment analysis confirmed the involvement of immune and cytokine signaling pathways. A predictive risk signature for pediatric CD is presented which represents a non-invasive supplementary tool for pediatric CD diagnosis.

Abstract
BACKGROUND In recent years, the global epidemiology of inflammatory bowel disease (IBD) has changed rapidly. AIMS We described the updated global IBD epidemiology results based on the 2019 Global Burden of Diseases, Injuries, and Risk Factors Study (GBD). METHODS We estimated the prevalence rate, death rate, years of life lost (YLLs), years lived with disability (YLDs), and disability-adjusted life-years (DALYs) from GBD 2019 in 195 countries and territories between 1990 and 2019. RESULTS The crude prevalence of IBD increased by 47% in 2019 globally. Accordingly, the age-standardized prevalence rate showed 19% decrease. The age-standardized death rates, YLDs, YLLs, and DALYs of IBD in 2019 decreased compared to those in 1990. The annual percentage change in age-standardized prevalence rate decreased most in United States and increased in East Asia and high-income Asia Pacific from 1990 to 2019. Continents with high socioeconomic index (SDI) had higher age-standardized prevalence rates compared to continents with low SDI. The 2019 age-standardized prevalence rate of high latitudes was higher than that of low latitudes in Asia, Europe, and North America. CONCLUSION The observed trends and geographic variations in IBD documented in the 2019 GBD study will aid policymakers in policy, research, and investment development.

Abstract
The human gastrointestinal microbiota contains a diverse consortium of microbes, including bacteria, protozoa, viruses, and fungi. Through millennia of co-evolution, the host-microbiota interactions have shaped the immune system to both tolerate and maintain the symbiotic relationship with commensal microbiota, while exerting protective responses against invading pathogens. Microbiome research is dominated by studies describing the impact of prokaryotic bacteria on gut immunity with a limited understanding of their relationship with other integral microbiota constituents. However, converging evidence shows that eukaryotic organisms, such as commensal protozoa, can play an important role in modulating intestinal immune responses as well as influencing the overall health of the host. The presence of several protozoa species has recently been shown to be a common occurrence in healthy populations worldwide, suggesting that many of these are commensals rather than invading pathogens. This review aims to discuss the most recent, conflicting findings regarding the role of intestinal protozoa in gut homeostasis, interactions between intestinal protozoa and the bacterial microbiota, as well as potential immunological consequences of protozoa colonization.

Abstract
Background To study the corresponding strategies to control inflammatory bowel disease (IBD), a comprehensive assessment of the disease burden is required. Herein, we present long-term trends in the burden of IBD in China over the last three decades, as well as its epidemiological features. Methods We characterized the burden of IBD in China using the GBD 2019 methods and results, based on prevalence, incidence, mortality, years lost (YLLs), years lived with disability (YLDs), and disability-adjusted life years (DALYs) estimated using the DisMod-MR 2-1. We also used joinpoint and age-period-cohort (apc) analysis methods to interpret IBD epidemiological characteristics and compare them to global prevalence trends. Results The age-standardized incidence and mortality rates in both sexes changed from 1.47 (95% CI: 1.24, 1.74) to 3.01 (95% CI: 2.59, 3.50) and from 0.86 (95% CI: 0.59, 1.16) to 0.30 (95% CI: 0.24, 0.35) per 100,000 people in China from 1990 to 2019. The age-standardized DALY rate in China decreased from 24.47 (95% CI: 17.88, 30.19) per 100,000 people in 1990 to 13.10 (95% CI: 10.29, 16.31) per 100,000 people in 2019. The average annual percentage change (AAPC) in age-standardized incidence, prevalence, and mortality rates for IBD in China were 2.51 (95% CI: 2.44, 2.57), 2.53 (95% CI: 2.41, 2.66), and -3.62 (95% CI: -3.85, -3.39). The effects of age, period, and cohort on incidence and mortality rates differed. Conclusions The increasing age-standardized prevalence rates are contributed to by the reduction in age-standardized mortality rates and DALYs, compounded by the rise in the age-standardized incidence rates between 1990 and 2019 in China. The burden of IBD in China will be a major public health challenge, given the country's large population base and aging population.

Abstract
Anti-tumor necrosis factor (TNF) biological therapy has generally been accepted as a standard therapeutic option in inflammatory bowel disease (IBD) patient who are refractory to steroids or immunomodulators. However, the primary and secondary nonresponse rates to anti-TNF bioagents in patients with IBD are high. To improve the response rate, anti-TNF bioagents must be offered to the appropriate IBD patients, and the withdrawal of anti-TNF bioagents needs to be done at the right time. In this context, reliable and reproducible biomarkers can provide important supportive information for clinicians to make correct decisions based on the patient’s individual situation. In this review, we summarized the current understanding of using mucosal TNF transcript (TNF) to improve the precision of anti-TNF biological therapy strategies in patients with ulcerative colitis (UC). Analysis of published literature showed that mucosal TNF could affect the precision of the early identification of candidates who will benefit from anti-TNF therapy prior to treatment, the assessment of response and mucosal healing, and the prediction of discontinuation of anti-TNF biological therapy and relapse after drug withdrawal. Challenges and limitations of using mucosal TNF as a biomarker in applying individualized anti-TNF biological therapy in patients with UC still remain and need to be further investigated.

Abstract
Microbe-host communication is essential to maintain vital functions of a healthy host, and its disruption has been associated with several diseases, including Crohn's disease and ulcerative colitis, the two major forms of inflammatory bowel disease (IBD). Although individual members of the intestinal microbiota have been associated with experimental IBD, identifying microorganisms that affect disease susceptibility and phenotypes in humans remains a considerable challenge. Currently, the lack of a definition between what is healthy and what is a dysbiotic gut microbiome limits research. Nevertheless, although clear proof-of-concept of causality is still lacking, there is an increasingly evident need to understand the microbial basis of IBD at the microbial strain, genomic, epigenomic, and functional levels and in specific clinical contexts. Recent information on the role of diet and novel environmental risk factors affecting the gut microbiome has direct implications for the immune response that impacts the development of IBD. The complexity of IBD pathogenesis, involving multiple distinct elements, suggests the need for an integrative approach, likely utilizing computational modeling of molecular datasets to identify more specific therapeutic targets.
