Background: Autoimmune diseases often coexist; however, the concomitant occurrence of systemic lupus erythematosus (SLE) and primary biliary cirrhosis (PBC) is rare. Therefore, this study aims to provide a comprehensive summary of evidence regarding the co-occurrence of SLE and PBC.

Methods: PubMed, Web of Science, ScienceDirect , and Google Scholar databases were systematically and comprehensively searched for records published up to February 2024. Full-text articles that aligned with the study's aim were included, while those published in languages other than English and those designed as case reports, reviews, conference abstracts, or editorials were excluded. Statistical analyses were performed using Comprehensive Meta-Analysis software, and methodological quality was assessed using the Newcastle-Ottawa Scale.

Results: Only 14 studies that met the inclusion criteria with 3944 PBC and 9414 SLE patients were included for review and analysis. Pooled data analysis revealed that approximately 1.1% of SLE patients have concomitant PBC (range: 0.02-7.5%), while around 2.7% of PBC patients concurrently have SLE (range: 1.3-7.5%). Furthermore, qualitative data analysis indicated that the prevalence of PBC in SLE patients presenting with hepatic dysfunction or abnormal liver enzymes ranges from 2 to 7.5%.

Conclusion: Although the concomitant occurrence of SLE and PBC is rare, the small proportion of patients where these diseases coexist warrants close monitoring by clinicians. This underscores the importance of surveillance to prevent their co-occurrence.

Objective: The objective of this study is to segment creeping fat and intestinal wall on computed tomography enterography (CTE) and develop a radiomic model to predict 1-year surgery risk in patients with Crohn's disease.

Methods: This retrospective study included 135 Crohn's disease patients who underwent CTE between January and December 2021 (training cohort) and 69 patients between January and June 2022 (test cohort). A total of 1874 radiomic features were extracted from the intestinal wall and creeping fat respectively on the venous phase CTE images, and radiomic models were constructed based on the selected features using the Boruta and extreme gradient boosting algorithms. The combined models were established by integrating clinical predictors and radiomic models. The receiver operating characteristic curve, calibration curve, and decision curve analyses were used to compare the predictive performance of models.

Results: In the training and test cohorts, the area under the curve (AUC) values of the creeping fat radiomic model for surgery risk stratification were 0.916 and 0.822, respectively, similar to the intestinal model with AUC values of 0.889 and 0.822. Moreover, the combined radiomic model was superior to the single models, showing good discrimination with the highest AUC values (training cohort: 0.963; test cohort: 0.882). Addition of clinical predictors to the radiomic models failed to significantly improve the diagnostic ability.

Conclusion: The CTE-based creeping fat radiomic model provided additional information to the intestinal radiomic model, and their combined radiomic model enables accurate surgery risk prediction of Crohn's disease patients within 1 year of CTE.

Background: Recently, a formula of subcutaneous infliximab (SC-IFX) has been approved for inflammatory bowel disease (IBD), demonstrating a better pharmacokinetic and immunogenic profiles, compared to intravenous infliximab (IV-IFX), with similar efficacy and safety.

Aim: The aim of this study is to evaluate the clinical, biochemical, and pharmacological outcomes of IBD patients in clinical remission, who switched from IV-IFX to SC-IFX, with a follow-up period of 6 months.

Methods: Retrospective cohort study, including IBD patients in clinical remission, previously medicated with IV-IFX, who switched to SC-IFX 120 mg every other week. Biochemical parameters were evaluated before the switch and 6 months after, namely infliximab serum concentrations, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and fecal calprotectin.

Results: Included 41 patients in clinical remission, 32 with Crohn's disease (78.0%) and 9 with ulcerative colitis (22.0%). All patients maintained clinical remission during the 6 months after the switch, with a treatment persistence rate of 100%, and no patients requiring corticosteroid therapy, switching back to IV-IFX, or IBD-related hospitalization. The mean infliximab serum concentrations were significantly higher after 6 months of SC-IFX (17.3 ± 6.6 vs. 9.1 ± 5.5 µg/ml, P < 0.001). However, there were no differences between values of ESR, CRP, and fecal calprotectin, before and after the switch (P = 0.791, P = 0.246, and P = 0.639). Additionally, none of the patients developed antibodies to infliximab.

Conclusion: Switching from IV-IFX to SC-IFX in IBD patients in clinical remission is effective and leads to higher infliximab serum concentrations, regardless of the combination with immunomodulatory therapy.

Background and aim: Recommendations on pregnancy, lactation, and contraception in women with Wilson disease are briefly stated in international guidelines but are not entirely homogeneous. Data regarding the management of these special events among patients with Wilson disease in Spain are lacking. We used the Wilson Registry platform of the Spanish Association for the Study of the Liver to question patients on their reproductive and gestational lives.

Methods: This was a multicentre ambispective study including adult women with Wilson disease in the Spanish Wilson Registry interviewed about their contraception, childbearing, pregnancy, and lactation experiences. Clinical and analytical data were extracted from the registry.

Results: The study included 92 women from 17 centres in Spain. Most (63%) reported having a previous pregnancy history. The rate of spontaneous miscarriages was 21.6%, mainly occurring in the first trimester and up to one third among undiagnosed patients. Most pregnant women received chelator therapy during pregnancy, but dose reduction was recommended in less than 10%. After delivery, artificial lactation predominated (60.3%) and its use was mainly based on physician's recommendations (68%). Up to 40% of the women included reported some concerns about their reproductive lives, mainly related to the potential drug toxicity to their children. Most of the patients considered the information given by specialists to be sufficient.

Conclusion: Gestational management among women with Wilson disease in Spain was found to be highly heterogeneous and frequently different from what is described in international guidelines. Education on rare liver diseases should be a priority for scientific societies in order to homogenize patient follow-up and recommendations.

Objective: The aim of this study is to systematically examine and compare the characteristics distinguishing colorectal adenomatous polyps from normal mucosal intestinal microbiota.

Methods: A total of 30 specimens were obtained from patients diagnosed with colorectal adenomatous polyps (adenoma group) who underwent endoscopic removal at Wenzhou People's Hospital between September 2021 and November 2021. Concurrently, 30 normal mucosal specimens were collected from patients without adenomatous polyps (control group). Subsequently, microbiome total DNA extraction was carried out, followed by PCR amplification targeting the V3-V4 region of the 16S rDNA. High-throughput sequencing was conducted using the Illumina MiSeq platform. Subsequent to sequencing, bioinformatics analysis was used to assess the diversity, composition, and functional aspects of the intestinal microbiota in both study groups.

Results: A notable dissimilarity in the microbiota structure was identified, specifically within the transverse colon, between these two groups (P < 0.05). Species composition analysis revealed that Escherichia, Fusobacterium, and Bacteroides were predominant bacteria in both groups, with Escherichia and Enterobacter displaying significant differences at the genera level between the control group and the adenoma group (P < 0.05). Correlation analysis and functional prediction demonstrated substantial disparities in interactions among dominant intestinal microbial genera within patients from both groups. Additionally, it was discovered that the intestinal microbiomes in patients in the adenoma group exhibited a significantly higher pathogenic potential.

Conclusion: Upon conducting a comprehensive analysis, it was discerned that the microbiota present in the transverse colon of the control group exhibited distinctive characteristics that may contribute to the maintenance of intestinal health.

Background and aims: Many children with Wilson's disease are complicated with dyslipidemia. The aim of this study was to investigate the risk factors for the development of fatty liver disease (FLD) in children with Wilson's disease.

Methods: We evaluated sex, age, weight, the disease course, treatment course, clinical classification, alanine transaminase (ALT), aspartate transaminase, γ-glutamyl transpeptidase, total biliary acid, triglyceride, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, homocysteine, uric acid, fibrinogen (FBG), creatinine, procollagen III N-terminal propeptide, laminin, hyaluronic acid, type IV collagen, and performed receiver operating characteristic curve analysis to investigate the forecast value of individual biochemical predictors and combined predictive indicators to evaluate FLD in Wilson's disease.

Results: The multivariate logistic regression analysis revealed that ALT [odds ratio (OR), 1.011; 95% confidence interval (CI), 1.004-1.02; P  = 0.006], uric acid (OR, 1.01; 95% CI, 1.002-1.018; P  = 0.017), FBG (OR, 3.668; 95% CI, 1.145-13.71; P  = 0.037), creatinine (OR, 0.872; 95% CI, 0.81-0.925; P  < 0.001), and laminin (OR, 1.01; 95% CI, 1.002-1.018; P  = 0.017) acted as independent risk factors in Wilson's disease complicated with FLD. The receiver operating characteristic curves for combined predictive indicators demonstrated an area under the curve values of 0.872, which was found to be a significant predictors for FLD in Wilson's disease.

Conclusions: We screened out the most important risk factors, namely ALT, uric acid, creatinine, FBG, and laminin for Wilson's disease complicated with FLD. The joint prediction achieved is crucial for identifying children with Wilson's disease complicated with FLD.

Purpose: Extrahepatic bile duct cancer (EBDC) is a compound malignant tumor mainly consisting of extrahepatic cholangiocarcinoma and gallbladder carcinoma. Most EBDC patients are diagnosed at an advanced stage characterized by distant metastases, and the liver is one of the common sites of metastasis. Hence, the purpose of this study is to investigate the clinicopathological features, identify prognostic risk factors, and assess the long-term prognosis of extrahepatic bile duct cancer liver metastasis (EBDCLM).

Methods: We identified 1922 eligible EBDCLM patients from the SEER database.Cox regression models were used to predict independent prognostic factors for overall survival (OS) and cancer-specific survival (CSS),and Kaplan-Meier survival curves were drawn. A nomogram was constructed based on the results of multivariate Cox analysis, and the predictive effect of the nomogram was evaluated.

Results: Age, surgery, chemotherapy, brain metastasis, and lung metastasis were common independent prognostic factors for OS and CSS, and radiotherapy and bone metastasis were independent prognostic factors for CSS. The Kaplan-Meier survival curves showed a significant increase in survival for patients aged less than or equal to 70 years, undergoing surgery and chemotherapy, and without lung metastases. The results showed that the nomogram constructed by us had good predictability and ha d strong clinical application value.

Conclusion: Our study identified age, surgery, chemotherapy, brain metastasis, and lung metastasis as independent prognostic factors for EBDCLM patients. The nomogram can accurately predict the survival probability, which is helpful for clinicians to assess the prognosis of patients with advanced EBDC and provide personalized clinical decisions.

Background: There is heterogeneous data on whether metabolic-associated steatohepatitis is an independent risk factor for portal vein thrombosis (PVT). We aim to compare the incidence of PVT in patients with cirrhosis with and without metabolic dysfunction-associated steatotic liver disease (MASLD).

Methods: This is a single-center retrospective study of patients with cirrhosis seen between 1 January 2016 and 31 January 2021. Patients with a history of hepatocellular cancer, liver transplant, Budd-Chiari syndrome, and intra-abdominal malignancies were excluded. Patients with cirrhosis were followed from their first hepatology visit for 180 days to determine the incidence of PVT. Cox proportional hazard regression was used to determine the relationship between MASLD with PVT.

Results: We analyzed data from 2785 patients with cirrhosis who met inclusion and exclusion criteria [mean age: 61.0 ± 12.3 years, 44.3% female, 63.8% Whites and mean model for end-stage liver disease-sodium (MELD-Na) score: 11.7 ± 6.1]. MASLD was present in 21.7% of patients. A total of 89 patients developed PVT during the follow-up, which was fewer in patients with MASLD [2.0% vs. 3.5%, P  = 0.04, unadjusted heart rate (HR): 0.60, 95% confidence interval (CI): 0.27-0.96, P  = 0.04]. After adjusting for the demographics, MASLD-related comorbid conditions and MELD-Na score, MASLD was associated with a lower incidence of PVT as compared to non-MASLD cirrhosis (HR: 0.44, 95% CI: 0.21-0.92, P  = 0.03). After adjusting for the indicators of Child-Pugh Turcotte score, the risk of PVT in patients with MASLD compared to non-MASLD was not statistically significant (HR: 0.50, 95% CI: 0.22-1.13, P  = 0.096).

Conclusion: PVT incidence was lower in patients with MASLD cirrhosis as compared to non-MASLD cirrhosis. However, the difference was not significantly different after adjusting for liver decompensation.

Background: There has been an increase in resistance to many of the antimicrobials used to treat Helicobacter pylori ( H. pylori ) nationally and internationally. Primary clarithromycin resistance and dual clarithromycin and metronidazole resistance are high in Ireland. These trends call for an evaluation of best-practice management strategies.

Objective: The objective of this study was to revise the recommendations for the management of H. pylori infection in adult patients in the Irish healthcare setting.

Methods: The Irish H. pylori working group (IHPWG) was established in 2016 and reconvened in 2023 to evaluate the most up-to-date literature on H. pylori diagnosis, eradication rates and antimicrobial resistance. The 'GRADE' approach was then used to rate the quality of available evidence and grade the resulting recommendations.

Results: The Irish H. pylori working group agreed on 14 consensus statements. Key recommendations include (1) routine antimicrobial susceptibility testing to guide therapy is no longer recommended other than for clarithromycin susceptibility testing for first-line treatment (statements 6 and 9), (2) clarithromycin triple therapy should only be prescribed as first-line therapy in cases where clarithromycin susceptibility has been confirmed (statement 9), (3) bismuth quadruple therapy (proton pump inhibitor, bismuth, metronidazole, tetracycline) is the recommended first-line therapy if clarithromycin resistance is unknown or confirmed (statement 10), (4) bismuth quadruple therapy with a proton pump inhibitor, levofloxacin and amoxicillin is the recommended second-line treatment (statement 11) and (5) rifabutin amoxicillin triple therapy is the recommend rescue therapy (statement 12).

Conclusion: These recommendations are intended to provide the most relevant current best-practice guidelines for the management of H. pylori infection in adults in Ireland.

Background: Sarcopenia is common in patients with cirrhosis and is a risk factor for increased mortality. Transjugular intrahepatic portosystemic shunt (TIPS) placement has been utilized in cirrhosis patients with decompensation . We investigated the role of sarcopenia in predicting mortality in patients undergoing TIPS.

Methods: We conducted a single-center retrospective study of 232 patients with cirrhosis who underwent TIPS between January 2010 and December 2015. Sarcopenia was defined by the psoas muscle index (PMI) cutoff value, calculated based on dynamic time-dependent outcomes using X-tile software. Kaplan-Meier analysis demonstrated the difference in survival in the sarcopenia group versus the non-sarcopenia group. . Univariate and multivariate analyses were used to identify the relationship between sarcopenia and post-TIPS mortality during a follow-up period of 1 year.

Results: For TIPS indications, 111 (47.84%) patients had refractory ascites, 69 (29.74%) patients had variceal bleeding, 12 (5.17%) patients had ascites, and 40 (17.24%) for other indications. The mean PMI was 4.40 ± 1.55. Sarcopenia was defined as a PMI value of <4.36 in males, and <3.23 in females. Sarcopenia was present in 96 (41.38%) of patients. . Kaplan-Meier analysis showed thatsarcopenia is associated with worse survival (log-rank P  < 0.01). Multivariate Cox regression analysis showed that sarcopenia is independently associated with worse survival during the 1-year follow-up period with an hazard ratio of 2.435 (95% CI 1.346-4.403) ( P  < 0.01), after adjusting for age, BMI, indications for TIPS, etiology for cirrhosis, and MELD score and stratified by sex.

Conclusion: Sarcopenia is an independent risk factor for 1-year mortality in patients undergoing TIPS and should be considered when patients are evaluated as a candidate for TIPS.
