Introduction

Renal disorders are among the extra-intestinal manifestations of inflammatory bowel disease (IBD), and treatments may also lead to renal failure. However, the incidence of end-stage renal disease (ESRD), defined as the need for renal replacement therapy (dialysis and/or renal transplantation (RT)), is poorly known. The primary objective of our study was to assess the incidence of ESRD in IBD patients, and to compare it with the general health insurance scheme population.

Aims & Methods

We conducted a prognostic cohort study based on data from the French National Health Insurance Database(SNDS). Prevalent cases of IBD affiliated to the general health insurance scheme during the period 2011-2020 were identified on the basis of declarations long-term diseases ALD 24 or the presence of 2 hospital stays for IBD with ICD-10 codes or a single stay with reimbursement of specific treatments. Incident cases of ESRD were identified on the basis of a stay with a RT or a period with dialysis sessions for at least 45 days. Crude incidence rates of ESRD were calculated over the period for the IBD and the non-IBD population, with their 95% confidence intervals.

Results

A total of 280,283 IBD patients were included in the study over the period 2011-2020, 134,567 with ulcerative colitis(UC) and 145,716 with Crohn’s disease(CD). The mean age at study inclusion was 39.8 (± 17.1) years. The M/F sex ratio was 0.9. The mean age at incidence of ESRD in the non-IBD population was 65.0 (±17.0) years, the M/F sex ratio cases was 1.7.
Among IBD patients, 534 patients began replacement therapy by dialysis or RT, they were younger than non-IBD patients (60.3(±16.7)years, P<0.001).The mean incidence rate of ESRD over the period was 26.4 per 100,000 person-years (IC95% 23.1-29.6), 480 (89.9%) patients entered ESRD by dialysis, and 54 (10.1%) by preemptive RT. In the non-IBD population the mean rate of ESRD was 15.9 per 100,000 person-years (IC95% 14.8- 17.1; P<0.0001 compared with IBD): 79,606 (94.5%) patients entered ESRD by dialysis, and 4,634 (5.5%) by RT (as compared with IBD,P<0.001). In subgroup analysis, the mean incidence rate of ESRD was 22.8 per 100,000 person-years (IC95% 18.9-26.7) in UC patients and 29.5 (IC95% 25.3-33.6) in CD patients (P<0,0001). The rates of preemptive RT were 12.4% in UC patients (87.6% dialysis) and 8.6% in CD patients (91.4% dialysis).
Over a median follow-up of 6.8 years, the survival rate after ESRD was 40.8% in ESRD-IBD patients VS 34.2% in ESRD non-IBD patients (P<0.001). This difference remained significant for patients under 65 (p<0.0073).
No significant difference for the risk of re-hospitalization after RT (p=0.84), of retransplantation during the follow-up period in RT patients (p=0.67), or for the risk of hospitalization for severe infection (p=0.97) after RT in patients from the general population compared with IBD patients. The same was true for the type of severe infections after RT (p= 0.068) and for the risk of solid and haematological cancer after RT (p=0.48). However, there was a significant difference in the type of first severe infection after RT(p=0.003), but we are waiting for the results to tell us which one.

Conclusion

The incidence of ESRD is significantly higher in IBD than in the general data base population, confirming the need for regular monitoring of renal function in our patients.
Survival after ESRD onset, is higher in IBD patients.
The high incidence of RT in the IBD population confirms that access to transplantation is not restricted in this
population.

Introduction

PEUGIC (Post-Endoscopy Upper Gastrointestinal Cancer) is defined as carcinoma in the upper gastrointestinal (GI) tract which was preceded by negative upper endoscopy in the last 3 years. According to current knowledge, the rate of PEUGIC is an important parameter of quality and should not exceed 10 %. The aim of this study was to evaluate the occurrence and risk factors of PEUGIC at non-university hospital in Frydek-Mistek (Czech Republic) between 2013 and 2023.

Aims & Methods

This is a retrospective analysis of the patients diagnosed with upper GI cancer from January 2013 to December 2023. The data analyzed included family history of upper GI cancer, indications of the examination, therapy, tumor location and histological type. Risk factors for PEUGIC were calculated using the Chi-squared test and Fisher's exact test, with p <0,05 considered significant.

Results

During the study period, a total of 22727 gastroscopies were performed in total, and 122 patients were diagnosed with upper GI cancer (88 men and 34 women), including 35 esophageal tumors, 80 gastric tumors, and 7 duodenal tumors. Family history of upper GI tumor was reported in 10 patients. PEUGIC was identified in 12 patients (9,84%, 9 men and 3 women, mean age 69,25 years), including 6 in the esophagus, 5 in the stomach, and 1 in the duodenum. Two patients had early detection as part of adequate surveillance (Barrett's esophagus, post-polypectomy). Thus, we can evaluate 10 patients as true PEUGIC (8,20%). The rate of PEUGIC was 17,14 % (6/35) in the esophagus, 6,25 % (5/80) in the stomach, and 14,3 % (1/7) in the duodenum. Tumor location (for esophagus p=0,086, for stomach p=0,065, for duodenum p=0,525), histology (for adenocarcinoma p=0,332, for spinocelular cancer p=0,402, for neuroendocrine tumor p=0,25), male gender (p=0,815), or family history of upper GI tumor (p=0,335) were not statistically significant risk factors for detecting PEUGIC.

Conclusion

The overall rate of PEUGIC at our institution over the 11-year study period was 9,86 %, without early detected lesions as part of adequate surveillance, it was 8,20 %. Early detection of PEUGIC, which indicate poorer endoscopy quality, need to be distinguished from early detection of carcinoma within adequate surveillance.

Introduction

The Janus kinase inhibitor (JAKi) upadacitinib (UPA) is approved for the treatment of moderate-to-severe ulcerative colitis (UC). However, safety warnings from the US Food and Drug Administration and the European Medicines Agency recommend caution when using JAKis in certain at-risk patients. These drug-class warnings are based on data from the ORAL Surveillance (OS) study, a safety outcomes trial comparing risk of cardiovascular (CV) events with the JAKi tofacitinib plus methotrexate vs a tumor necrosis factor inhibitor (TNFi) plus methotrexate in patients with rheumatoid arthritis (RA) who were ≥50 years of age with ≥1 CV risk factor.¹ An OS study post hoc analysis observed higher major adverse CV event risk with tofacitinib vs TNFi in patients with RA plus a history of atherosclerotic CV disease (ASCVD).² CV risk profiles may be different for patients with UC vs RA.

Aims & Methods

This analysis aimed to describe the CV risk profile for patients with UC relative to the CV risk profile for patients with RA included in the OS study. Patients with UC enrolled in the placebo-controlled UPA U-ACHIEVE and U-ACCOMPLISH induction trials³ were evaluated for the OS study inclusion criteria (age ≥50 years, ≥1 CV risk factor [CV event history, hypertension, diabetes mellitus, smoking/tobacco use, and high-density lipoprotein cholesterol <1.034 mmol/L]). In addition, history of coronary artery disease or ASCVD and 10-year CV disease risk for patients with UC with no prior CV disease were estimated using the American College of Cardiology ASCVD risk score calculation.

Results

Overall, 268/1097 (24.4%) patients with UC met the OS criteria and 624 (56.9%) had ≥1 CV risk factor, regardless of age. Few patients with UC (30; 2.7%) had a history of ASCVD, in contrast to the RA population (640/4362; 14.7%). The distribution of 10-year ASCVD risk scores for patients with UC was similar between the placebo and UPA treatment arms, but markedly different from patients with RA (Table). Most patients with UC were categorized as low risk (938; 85.5%), with another 52 (4.7%) categorized as borderline risk, 51 (4.6%) as intermediate risk, and 26 (2.4%) as high risk.

Conclusion

The majority of patients in the UC trials had low estimated CV risk, while the majority of patients with RA included in the OS study were at intermediate or high CV risk. Caution should be used when extrapolating adverse events data from patients with RA to risk discussions for patients with UC.

Introduction

Transient elastography (TE) by Fibroscan® is a widespread method for non-invasive evaluation of liver stiffness measurement (LSM). Point-shear wave elastography (pSWE) is an alternative non-invasive method for this type of assessment. Transient elastography is also able to evaluate hepatic steatosis by the function Controlled Attenuation Parameter (CAP).

Aims & Methods

We aimed to compare the results of TE and pSWE for fibrosis assessment in patients with non-alcoholic steatohepatitis (NASH), stratified by the degree of steatosis.
​Consecutive patients with established diagnosis of NASH attending our Gaastroenterology Unit underwent liver stiffness measurement (LSM) by both TE and pSWE. Liver steatosis was measured by CAP and the severity was graded into S0-S3. At least 10 measurements were performed and results were expressed as median with interquartile range. Statistical analysis was conducted by Pearson’s test for correlation and linear regression. Bland-Altman graphs with bias and ROC curves with estimation of sensitivity, specificity, and area under the curve (AUC) were drawn.

Results

Seventy-seven patients were recruited (17 females, 60 males, aging 54.1 ± 13.9). The overall correlation between TE and pSWE was moderate (r=0,63, p < 0.001). Linear regression showed a “b” coefficient of 0.99 ± 0.033. The Bland-Altman plot found a bias of -0,52 and only six valued exceeded the 95% CI limits. When considering patients with mild steatosis (S1), we found a strong correlation (r=0.81, 95% CI 0.39-0.95, p=0.003). The highest correlation between TE and pSWE was recorded for S2 subjects: r=0.90 (95% CI, 0.64-0.98, p<0.001). The correlation was low in S3 patients (r=0.42, 95% CI, 0.09-0.67, p=0.001). A cut-off of 11.15 kPa of pSWE had sensitivity=87,50 % and specificity=97,10% to detect relevant fibrosis, with an AUC=0.98 compared to TE.

Conclusion

pSWE and TE showed comparable LSM in NASH. A good concordance was observed in patients with mild or moderate liver steatosis, while in S3 patients we observed a weaker agreement between the two techniques.

Introduction

Steatotic liver disease (SLD) encompasses a spectrum of conditions, including metabolic dysfunction-associated SLD (MASLD), alcohol-related liver disease (ALD), and the overlapping category of MetALD. SLD affects more than a third of adults globally, but the majority remain undiagnosed, partially due to its lack of symptoms and limited awareness among patients and physicians. Adults undergoing screening colonoscopy, typically aged ≥50 years, represent a key population for targeted SLD detection, as they have a higher prevalence of cardiometabolic risk factors and is already engaged with preventive healthcare.

Aims & Methods

We examined 610 consecutive individuals aged ≥50 years with no known history of chronic liver disease who were referred for a colonoscopy for colorectal cancer screening. The protocol included sonographic assessment of liver steatosis and point shear wave elastography (pSWE) for liver fibrosis quantification, anthropometric measurements, biochemistry, medical history and alcohol intake evaluation. From the collected data, non-invasive fibrosis scores were calculated and used for aetiological and risk stratification.

Results

A total of 543 patients were included in the final analysis, after excluding patients with an invalid pSWE measurement (5.3%, n=29) and then excluding patients with incomplete results (n=38). The median age was 64 years (IQR 57-70) and 54.0% were male. The median BMI was 28.7 kg/m² (IQR 25.8–31.4) in males and 28.3 kg/m² (IQR 24.2-31.5) in females. SLD was identified in 63.4 % (n=344) of participants. Elevated liver stiffness (pSWE ≥ 1.30 m/s) was found in 26.9 % (n=146), and 4.8% (n=26) had values ≥1.70 m/s, suggestive of compensated advanced chronic liver disease. Among patients with pSWE ≥ 1.30 m/s, MASLD was the predominant aetiology (69.9%, n=102), followed by MetALD (15.8%, n=23), ALD (1.4%, n=2), cryptogenic (11.6%, n=17) and other etiologies (1.4%, n=2). Preselection using EASL-EASD-EASO criteria (i.e. presence of type 2 diabetes or central obesity plus ≥1 cardiometabolic risk factor and elevated liver enzymes) would have detected 365 at-risk individuals (67.2% of the cohort) of whom 55.9% (n=204) had a FIB-4 index ≥1.30. This approach would have identified only 30.4% (n=38) of all the patients with MASLD/MetALD with elevated liver stiffness (n=125).

Conclusion

Opportunistic screening for SLD in patients undergoing screening colonoscopy could be a useful strategy for detecting asymptomatic and potentially progressive liver disease. This approach identified a high prevalence of SLD (63.4%) and elevated liver stiffness (26.9%) in this population, primarily due to MASLD and MetALD. The integration of ultrasound and elastography added minimal burden to the existing workflow while enabling early risk stratification without the need for additional patient visits or referrals.
