Association Between Cardiovascular Health and Cirrhosis and Mortality: Insights From a Comprehensive Cross-sectional Study.

GOAL: We aim to explore the relationship between the newly introduced CVH indicator "Life's Essential 8 (LE8)" and cirrhosis. BACKGROUND: The global burden of cirrhosis is increasing, with a rising number of deaths, leading to significant societal and economic challenges. Cardiovascular health (CVH) has been found to have potential associations with liver diseases. MATERIALS AND METHODS: All participants aged 20 and older from National Health and Nutrition Examination Survey 2005 to 2018 were included. CVH was accessed by LE8, consisting of 4 health behaviors (diet, physical activity, nicotine exposure, and sleep health) and 4 health factors (body mass index, lipid levels, blood sugar, and blood pressure). Cirrhosis was determined based on abnormal liver function test results, with an aspartate aminotransferase to platelet ratio index >2. Participants' mortality status was obtained by matching with the National Death Index and all-cause mortality served as the follow-up endpoint. RESULTS: This extensive cross-sectional study reveals that LE8 was not associated with cirrhosis. A higher health behaviors score was associated with lower cirrhosis. Moreover, there is an inverse U-shaped relationship between the LE8 score and all-cause mortality in participants with cirrhosis, signifying a decrease in all-cause mortality when LE8 surpasses 60. A greater health behaviors score is linked to a decreased proportion of all-cause mortality in cirrhosis patients. CONCLUSION: Maintaining better health behaviors may be beneficial for cirrhosis, especially through a balanced diet, regular exercise, smoking cessation, and quality sleep.

Clinical manifestations, diagnosis and long-term prognosis of adult autoimmune enteropathy: Experience from Peking Union Medical College Hospital.

BACKGROUND: Autoimmune enteropathy (AIE) is a rare disease whose diagnosis and long-term prognosis remain challenging, especially for adult AIE patients. AIM: To improve overall understanding of this disease's diagnosis and prognosis. METHODS: We retrospectively analyzed the clinical, endoscopic and histopathological characteristics and prognoses of 16 adult AIE patients in our tertiary medical center between 2011 and 2023, whose diagnosis was based on the 2007 diagnostic criteria. RESULTS: Diarrhea in AIE patients was characterized by secretory diarrhea. The common endoscopic manifestations were edema, villous blunting and mucosal hyperemia in the duodenum and ileum. Villous blunting (100%), deep crypt lymphocytic infiltration (67%), apoptotic bodies (50%), and mild intraepithelial lymphocytosis (69%) were observed in the duodenal biopsies. Moreover, there were other remarkable abnormalities, including reduced or absent goblet cells (duodenum 94%, ileum 62%), reduced or absent Paneth cells (duodenum 94%, ileum 69%) and neutrophil infiltration (duodenum 100%, ileum 69%). Our patients also fulfilled the 2018 diagnostic criteria but did not match the 2022 diagnostic criteria due to undetectable anti-enterocyte antibodies. All patients received glucocorticoid therapy as the initial medication, of which 14/16 patients achieved a clinical response in 5 (IQR: 3-20) days. Immunosuppressants were administered to 9 patients with indications of steroid dependence (6/9), steroid refractory status (2/9), or intensified maintenance medication (1/9). During the median of 20.5 months of follow-up, 2 patients died from multiple organ failure, and 1 was diagnosed with non-Hodgkin's lymphoma. The cumulative relapse-free survival rates were 62.5%, 55.6% and 37.0% at 6 months, 12 months and 48 months, respectively. CONCLUSION: Certain histopathological findings, including a decrease or disappearance of goblet and Paneth cells in intestinal biopsies, might be potential diagnostic criteria for adult AIE. The long-term prognosis is still unsatisfactory despite corticosteroid and immunosuppressant medications, which highlights the need for early diagnosis and novel medications.

Consistent efficacy outcomes between phase 2 and phase 3 trials in Crohn's disease or ulcerative colitis in adults: a meta-analysis.

INTRODUCTION: The approval of novel biologic agents and small molecules for the treatment of Crohn's disease (CD) and ulcerative colitis (UC) is dependent on phase 3 randomized controlled trials (RCTs). However, these trials sometimes fail to achieve the expected efficacy outcomes observed in phase 2 trials. METHODS: We conducted a systematic review of RCTs that evaluated biologic agents and small molecules using paired regimens in both phase 2 and phase 3. We searched Medline, EMBASE, and Cochrane databases up until February 13, 2024. The revised Cochrane tool was utilized to assess the risk of bias. A generalized linear mixed-effects model (GLMM) was employed to estimate the odds ratios (ORs) for efficacy outcomes in phase 2 trials compared to phase 3. RESULTS: We identified a total of 23 trials with 10 paired regimens for CD and 30 trials with 11 paired regimens for UC. The GLMM analysis revealed that phase 2 CD trials had higher outcomes measured by the Crohn's Disease Activity Index (CDAI) by 9-13% without statistical significance: CDAI-150: OR, 1.12 (95% CI 0.83-1.51, p = 0.41); CDAI-100: OR, 1.09 (95% CI 0.88-1.35, p = 0.40); or CDAI-70: OR, 1.13 (95% CI 0.61-2.08, p = 0.66). For UC, two efficacy outcomes were estimated to be equally reported in phase 2/phase 3 pairs: clinical remission: OR, 1.00 (95% CI 0.83-1.20, p = 0.96); endoscopic improvement: OR, 0.98 (95% CI 0.83-1.15, p = 0.79). However, the rate of clinical response was underestimated in phase 2 by 19%: OR, 0.81 (95% CI 0.70-0.95, p = 0.03). The inclusion criterion for the type of Mayo score for UC had a significant interaction with the study phase to influence the difference in clinical response (p = 0.002). CONCLUSIONS: Our findings suggest that the main efficacy outcomes for CD and UC remain consistent between phase 2 and phase 3 trials, except for UC response rates. The efficacy data obtained from phase 2 trials can be considered reliable for the design of subsequent phase 3 trials. REGISTRATION: PROSPERO (CRD42023407947).

Fragility index analysis for randomized controlled trials of approved biologicals and small molecule drugs in inflammatory bowel diseases.

INTRODUCTION: Biologics and small molecules have been increasingly applied in Crohn's disease (CD) and ulcerative colitis (UC). But the robustness of their trials has not been evaluated. METHODS: We initially collected all the approved biologics or small molecules for CD or UC up to December 1, 2022. Databases were then queried by keywords in chemical name and CD or UC. Randomized controlled trials (RCTs) in the two-arm, 1:1 design were included. Fragility index (FI) and fragility quotient (FQ) were subsequently calculated. RESULTS: We included twenty-eight RCTs, including nine pivotal trials listed in approval labels, nineteen non-pivotal trials not included in the labels. The median sample size was 99 [IQR, 60-262] and the median number of loss-of-follow-up (LFU) was 14 [IQR, 8-43]. Pivotal trials in the labels had the median FI of 8 [IQR, 4-14, n = 6] that was marginally higher than non-pivotal trials (3 [IQR, 2-4], p = 0.08). The median FQ was 0.0330 [IQR, 0.1220-0.0466] and 0.0310 [IQR, 0.0129-0.0540] for pivotal and non-pivotal trials, respectively (p = 1.0). The sample size and FI were significantly correlated (Spearman correlation coefficient [r] = 0.56, 95 %CI 0.21-0.78, p = 0.003). The number of total events was also significantly correlated with FI (r = 0.53, 95 %CI 0.17-0.77, p = 0.006). Study p-values were significantly associated with FI (p = 0.01): trials with p-values < 0.001 had the highest median FI of 10 [IQR, 6-17]. No factor was found strongly correlated with FQ. CONCLUSION: Results from trials assessing administration-approved biologics or small molecules for treating CD or UC were vulnerable to small changes by measuring FI or FQ. Pivotal studies contributing to regulatory approvals exhibited a relatively higher degree of resilience compared to non-pivotal trials.

Differences in the incidence and mortality of digestive cancer between Global Cancer Observatory 2020 and Global Burden of Disease 2019.

The burden of digestive cancers is increasing worldwide. The Global Cancer Observatory (GLOBOCAN) 2020 and the Global Burden of Disease (GBD) 2019 are two primary cancer databases, which have a significant impact on policy formulation and resource allocation. We aim to compare the incidence and mortality of digestive cancers between them. Digestive cancer (esophageal, stomach, colorectal, liver, gallbladder and pancreatic cancer) incidence was obtained from the Cancer Today and GBD 2019 result tool. The top five countries with the most or minor difference between GLOBOCAN 2020 and GBD 2019 in age-standardized incidence rates (ASIRs) of digestive cancers were identified. A systematic search on the incidence of specific digestive cancer in selected countries from PubMed and Embase was conducted, and 20 of 281 publications were included. The most significant differences in digestive cancers incidence were commonly found in Asian countries (70%), particularly Indonesia, Vietnam and Myanmar, located in Southeast Asia. The ASIRs for most digestive cancers, except liver cancer, in GLOBOCAN 2020 were higher than those in GBD 2019. Gallbladder cancer had the highest average ratio, followed by liver cancer. The most commonly used standard population was Segi's standard population, followed by the World Health Organization standard population. The data sources nor the processing methods of GLOBOCAN 2020 and GBD 2019 were not similar. Low- and middle-income countries without population-based cancer registries were more likely to have selection bias in data collection and amplify regional variations of etiological factors. Better judgments on the quality of cancer data can be made.

The efficacy and safety of anti-tumor necrosis factor agents in the treatment of intestinal Behcet's disease, a systematic review and meta-analysis.

BACKGROUND AND AIM: Behcet's disease is a systemic vasculitis that can involve gastrointestinal tract. This is a systematic review and meta-analysis evaluating the efficacy and safety of anti-tumor necrosis factor (TNF) agents in treating patients with intestinal Behcet's disease. METHODS: We conducted searches on PubMed, Embase, and Cochrane. Data from eligible studies were used to calculate the pooled estimate of proportions of clinical remission, mucosal healing at Months 3, 6, 12, and 24 as well as the pooled incidence of adverse drug reactions. And subgroup analysis based on the specific type of anti-TNF agents was performed. RESULTS: Of the 828 studies initially identified, 13 were included finally, all of which were single-arm cohort studies. The pooled proportions of clinical remission at Months 3, 6, 12, and 24 were 0.61 (95%CI 0.48-0.78), 0.51 (95%CI 0.40-0.66), 0.57 (95%CI 0.48-0.67), and 0.38 (95%CI 0.16-0.88), respectively. The pooled proportions of mucosal healing at Months 3, 6, 12, and 24 were 0.66 (95%CI 0.50-0.86), 0.82 (95%CI 0.48-0.98), 0.65 (95%CI 0.51-0.81), and 0.69 (95%CI 0.39-1.00), respectively. The pooled estimate of proportion of overall adverse drug reactions for infliximab was 0.22 (95%CI 0.07-0.69). CONCLUSIONS: Anti-TNF agents, including infliximab and adalimumab, were an efficient therapy for intestinal Behcet's disease. The safety of anti-TNF agents used in the treatment of intestinal Behcet's disease was acceptable.

Long-term Disease Behavior and Surgical Intervention Analysis in Hospitalized Patients With Crohn's Disease in China: A Retrospective Cohort Study.

BACKGROUND: There is lack of real-world data for disease behavior and surgery of Crohn's disease (CD) from large-scale Chinese cohorts. METHODS: Hospitalized patients diagnosed with CD in our center were consecutively included from January 2000 to December 2018. Disease behavior progression was defined as the initial classification of B1 to the progression of B2 or B3. Clinical characteristics including demographics, disease classification and activity, medical therapy, development of cancers, and death were collected. RESULTS: Overall, 504 patients were included. Two hundred thirty-one (45.8%) patients were initially classified as B1; 30 (13.0%), 71 (30.7%), and 95 (41.1%) of them had disease progression at the 1-year follow-up, 5-year follow-up, and overall, respectively. Patients without location transition before behavior transition were less likely to experience behavior progression. However, patients without previous exposure to a corticosteroid, immunomodulator, or biological agent had a greater chance of experiencing behavior progression. When the long-term prognosis was evaluated, 211 (41.9%) patients underwent at least 1 CD-related surgery; 108 (21.4%) and 120 (23.8%) of these patients underwent surgery before and after their diagnosis, respectively. An initial classification as B1, no behavior transition, no surgery prior to diagnosis, and previous corticosteroid exposure during follow-up were associated with a lower risk of undergoing surgery. CONCLUSIONS: This study depicts the clinical features and factors associated with behavior progression and surgery among hospitalized CD patients in a Chinese center. Behavior progression is associated with a higher probability of CD-related surgery, and strengthened therapies are necessary for them in the early phase.

Common Immune-Related Adverse Events of Immune Checkpoint Inhibitors in the Gastrointestinal System: A Study Based on the US Food and Drug Administration Adverse Event Reporting System.

Immune checkpoint inhibitors (ICIs) have revolutionized cancer treatment; however, immune-related adverse events (irAEs) in the gastrointestinal (GI) system commonly occur. In this study, data were obtained from the US Food and Drug Administration adverse event reporting system between July 2014 and December 2020. Colitis, hepatobiliary disorders, and pancreatitis were identified as irAEs in our study. Reporting odds ratio (ROR) with information components (IC) was adopted for disproportionate analysis. A total of 70,330 adverse events were reported during the selected period, 4,075 records of which were associated with ICIs. GI toxicities have been reportedly increased with ICI, with ROR025 of 17.2, 6.7, and 2.3 for colitis, hepatobiliary disorders, and pancreatitis, respectively. The risks of colitis, hepatobiliary disorders, and pancreatitis were higher with anti-CTLA-4 treatment than that with anti-PD-1 (ROR025 2.6, 1.3, and 1.1, respectively) or anti-PD-L1 treatment (ROR025 4.8, 1.3, and 1.3, respectively). Logistic analysis indicated that hepatobiliary disorders and pancreatitis more frequently occurred in female patients (adjusted odds ratio, 1.16 and 1.52; both p < 0.05). Consistently, polytherapy was a strong risk factor for colitis (adjusted odds ratio 2.52, p < 0.001), hepatobiliary disorders (adjusted odds ratio 2.50, p < 0.001), and pancreatitis (adjusted odds ratio 2.29, p < 0.001) according to multivariate logistic analysis. This pharmacovigilance analysis demonstrated an increased risk of all three GI irAEs associated with ICI therapies. The comparative analysis offered supportive insights on selecting GI irAEs for patients treated with ICIs.

Artificial Neural Network Analysis-Based Immune-Related Signatures of Primary Non-Response to Infliximab in Patients With Ulcerative Colitis.

Infliximab (IFX) is an effective medication for ulcerative colitis (UC) patients. However, one-third of UC patients show primary non-response (PNR) to IFX. Our study analyzed three Gene Expression Omnibus (GEO) datasets and used the RobustRankAggreg (RRA) algorithm to assist in identifying differentially expressed genes (DEGs) between IFX responders and non-responders. Then, an artificial intelligence (AI) technology, artificial neural network (ANN) analysis, was applied to validate the predictive value of the selected genes. The results showed that the combination of CDX2, CHP2, HSD11B2, RANK, NOX4, and VDR is a good predictor of patients' response to IFX therapy. The range of repeated overall area under the receiver-operating characteristic curve (AUC) was 0.850 ± 0.103. Moreover, we used an independent GEO dataset to further verify the value of the six DEGs in predicting PNR to IFX, which has a range of overall AUC of 0.759 ± 0.065. Since protein detection did not require fresh tissue and can avoid multiple biopsies, our study tried to discover whether the key information, analyzed by RNA levels, is suitable for protein detection. Therefore, immunohistochemistry (IHC) staining of colonic biopsy tissues from UC patients treated with IFX and a receiver-operating characteristic (ROC) analysis were used to further explore the clinical application value of the six DEGs at the protein level. The IHC staining of colon tissues from UC patients confirmed that VDR and RANK are significantly associated with IFX efficacy. Total IHC scores lower than 5 for VDR and lower than 7 for RANK had an AUC of 0.828 (95% CI: 0.665-0.991, p = 0.013) in predicting PNR to IFX. Collectively, we identified a predictive RNA model for PNR to IFX and explored an immune-related protein model based on the RNA model, including VDR and RANK, as a predictor of IFX non-response, and determined the cutoff value. The result showed a connection between the RNA and protein model, and both two models were available. However, the composite signature of VDR and RANK is more conducive to clinical application, which could be used to guide the preselection of patients who might benefit from pharmacological treatment in the future.

The Long-Term Clinical and Endoscopic Outcomes of Cronkhite-Canada Syndrome.

INTRODUCTION: The prognosis of Cronkhite-Canada syndrome (CCS) is considered poor. Despite the recent therapeutic improvements, the survival outcomes and prognostic factors have been less studied. This study aimed to investigate the long-term clinical and endoscopic outcomes of CCS. METHODS: Thirty-one patients diagnosed since 1999 and followed up for over 6 months were included. Data regarding survival outcomes, clinical symptoms, endoscopic findings, and treatment were collected and analyzed. R (version 3.6.1) was used to perform the survival analyses. RESULTS: The median (interquartile range) follow-up time was 42.5 (19.5-85.8) months. The 5-year overall survival (OS) was 87.4%. The maximum gastric polyp size over 2 cm was associated with worse OS (Hazard ratio [HR]: 18, 95% confidence interval [CI]: 1.6-210, P = 0.021). The 3-year relapse-free survival (RFS) after corticosteroid treatment was 66.8%. Age older than 60 years (HR: 7.0, 95% CI: 1.5-33.0, P = 0.015) and maximum gastric polyp size over 2 cm (HR: 6.0, 95% CI: 1.6-23.0, P = 0.009) were associated with worse RFS. Twenty-three patients received follow-up endoscopic examinations, with a median (interquartile range) follow-up time of 29.0 (14.0-53.5) months. Eight (34.8%) and 12 (52.2%) patients achieved complete remission under gastroscopy and colonoscopy, respectively. Colonic lesions showed a tendency of earlier responses compared with gastric lesions (25.0 [11.3-39.8] months vs 31.0 [21.0-39.8] months). DISCUSSION: Patients with CCS usually responded well to glucocorticoids with a fairly good 5-year survival rate. Large gastric polyp was associated with worse OS and RFS, whereas age older than 60 years was another predictor for worse RFS. Diffuse gastrointestinal lesions partly or completely resolved after treatment, and colonic lesions showed a better response than gastric lesions.

Interaction of Serum microRNAs and Serum Folate With the Susceptibility to Pancreatic Cancer.

OBJECTIVES: The aim of this study was to investigate whether 6 candidate serum miRNAs and their interactions with serum folate level were associated with the risk for pancreatic cancer (PC). METHOD: A hospital-based case-control study including 74 incident PC cases and 74 controls was conducted. Serum folate and miRNAs were determined by radioimmunoassay and real-time quantitative polymerase chain reaction, respectively. Cell lines AsPC-1 and PANC-1 were used for in vitro study. RESULTS: MiR-16 was elevated (P = 0.030-0.043) and miR-103 was reduced (P = 0.018-0.020) in PC after adjustment for age, sex, and smoking; however, after additional adjustment for folate, only miR-103 was significantly different between cases and controls (P = 0.010). After converting the relative expression of miRNAs into binary variables and adjusting for age, sex, smoking, and folate, the subjects with low miR-103 or low miR-601 were observed to have a higher risk for PC, with odds ratios of 2.33 (95% confidence interval, 1.06-5.10) and 2.37 (95% confidence interval, 1.07-5.26), respectively. Multifactor dimensionality reduction analysis showed a significant interaction for miR-16, folate, and smoking (cross-validation consistency, 10/10; mean testing accuracy, 0.696; P = 0.013). Interaction between miR-16 and folate was also verified in the AsPC-1 cells. CONCLUSION: Serum miR-103; miR-601; and interactions among serum miR-16, folate, and smoking are associated with PC.
