Introduction

Inflammatory Bowel Diseases (IBD) patients are associated to a higher risk of developing colonic dysplasia and colorectal cancer due to long-standing colonic inflammation and immunosuppressant therapies. They seem to have also a higher risk of developing extra-intestinal malignancies, such as cholangiocarcinoma, skin cancer, and others. Different studies have been conducted to assess whether a correlation exists between IBD, medical treatments and cancers, but the results are controversial.

Aims & Methods

Our study aimed to evaluate the risk factors of malignancies in our IBD patients, particularly considering the medication history.
In this single-center retrospective study, IBD patients with a history of at least one malignancy post-IBD diagnosis followed at the Gastroenterology Unit of Azienda Ospedale Università Padova were enrolled (cases). Demographics and clinical data, including medication information, were collected before and at the time of malignancy diagnosis. A group of IBD patients, matched by sex and age, without a malignancy history were also included (controls), considering the medications taken before and at the time of the last visit for comparison.

Results

Among 2213 IBD patients followed at our center (1212 males, 1040 CD, and 1173 UC), 153 cases (80 UC and 73 CD, 46.4% males, mean age at diagnosis: 38.4±14.7) and 50 sex and matched controls were included (30 UC and 20 CD, 52% males, mean age at diagnosis: 38.9±0.8). Twelve patients had two malignancies, and 2 had three. For the scope of our study, we considered only the first tumor. Results are shown in the Table 1. The mean time from IBD diagnosis to the first tumor was 15 years (SD 10.5). Considering malignancies, the most frequent in our population were breast cancer (27/1001 females, 2.7%), colorectal cancer (23/2213, 1%), melanoma (24/2213, 1.1%), and non-melanoma skin cancer (15/2213, 0.7%). Patients with colon cancer were younger at the time of IBD diagnosis (31.0±15.8 vs. 38.9±0.8), while patients with prostate and urinary cancer (11/2213, 0.5%) were older compared to controls (49.6±13.7 vs. 38.9±0.8). A lower percentage of patients with colon (13%), breast (4%), and prostate cancers (9.1%) had taken biological therapy before cancer occurrence, as compared to controls (44%, p<0.01). Finally, we observed a significantly higher number of melanoma and breast cancer patients taking azathioprine (AZA) at the time of cancer diagnosis for more than 4 years. No difference in terms of duration of AZA and biological therapies before cancer diagnosis was observed.

Conclusion

Our study found that biological therapy was not associated to malignancies, while azathioprine use was associated with breast and melanoma cancers. A younger age at diagnosis was associated with colon cancer, while an older age with prostate and urinary cancers.

Introduction

Transjugular intrahepatic portosystemic shunt (TIPS) is a well-established interventional treatment for complications of portal hypertension. Post-TIPS transient or persistent acute bilirubin elevation (ABE) is common, possibly due to impairment of portal perfusion. The outcomes of patients with ABE is not clear.

Aims & Methods

This study investigates the incidence, clinical outcomes, and prognostic factors associated with ABE in cirrhotic patients undergoing TIPS. Between January 2009 and November 2022, 1,287 patients (882 men, 405 women; mean age, 52 years) were included in this retrospective analysis. ABE was defined as a total serum bilirubin level exceeding 85.5 μmol/L (5 mg/dL) within one week after TIPS. Statistical analyses included the Kaplan-Meier method, log-rank test, multivariate Cox regression, and stepwise regression.

Results

Post-TIPS ABE occurred in 67 patients (5.2%). Patients with ABE had significantly higher baseline Child-Pugh scores (8.39 ± 1.62 vs. 7.41 ± 1.54, P < 0.001) and MELD scores (13.98 ± 4.13 vs. 10.72 ± 2.99, P < 0.001). Refractory ascites as the TIPS indication was more frequent in the ABE group (17.91% vs. 7.21%, P = 0.001). ABE was associated with a significantly higher incidence of hepatic encephalopathy (HE): 62.7% vs. 38.3% at 1 year and 80.6% vs. 62.8% at 5 years (P = 0.042). During follow-up, 441 patients died, with causes including liver failure (n = 129), gastrointestinal bleeding (n = 100), sepsis (n = 16), multi-organ dysfunction (MOD) (n = 41), hepatocellular carcinoma (HCC) (n = 43), and other or unknown causes (n = 112). Survival rates were significantly lower in the ABE group: 1-year (52.2% vs. 85.2%), 3-year (34.3% vs. 68.3%), and 5-year (25.4% vs. 46.6%) (P < 0.001). Multivariate analysis identified ABE (hazard ratio [HR]: 2.09; 95% confidence interval [CI]: 1.41–3.10; P < 0.001), age (HR: 1.05; 95% CI: 1.04–1.06; P < 0.001), albumin level (HR: 0.95; 95% CI: 0.94–0.97; P < 0.001), pre-TIPS grade 4 HE (HR: 1.93; 95% CI: 1.19–3.14; P = 0.008), presence of HCC (HR: 1.81; 95% CI: 1.24–2.65; P = 0.002), baseline MELD score (HR: 1.09; 95% CI: 1.04–1.14; P < 0.001), and change in MELD score (HR: 1.08; 95% CI: 1.06–1.11; P < 0.001) as independent predictors of post-TIPS mortality.

Conclusion

AEB is not rare in cirrhotic patients undergoing TIPS and is associated with an increased risk of HE and mortality. Risk factors for post-TIPS mortality include AB, older age, higher and fluctuating MELD scores, concurrent HCC, severe pre-TIPS HE, and lower albumin levels. Early identification, close monitoring, and prompt management of complications are essential to improving clinical outcomes and reducing the risk of liver failure after TIPS.

Introduction

Non-invasive biomarkers are needed to improve the management of eosinophilic esophagitis (EoE). We investigated whether eosinophil and lymphocyte counts could be used to diagnose EoE among patients with dysphagia and assess histological, endoscopic, and clinical disease activity in patients with known EoE.

Aims & Methods

This was a prospective study conducted at four EoE referral centers (Pisa, Padova, Humanitas Research Hospital, Milano Policlinico San Donato). We enrolled consecutive patients undergoing esophagogastroduodenoscopy (EGD) for suspected or known EoE who had performed blood counts within one month before EGD. Histological remission and non-EoE-related dysphagia (NED) were defined according to current guidelines on EoE. Endoscopic characteristics were classified according to the EoE reference score (EREFS). Demographic, clinical and full blood count data were collected. After the EGD, all patients completed the Dysphagia Symptom Questionnaire over 14 days (DSQ). Kruskal-Wallis Rank Sum Test and Pearson’s Chi-squared were used for comparisons. ROC curve analysis was used to assess the diagnostic accuracy. Spearman’s test was used for correlations. Significance threshold was p<0.05.

Results

We included 210 consecutive patients. Of these, 123 had EoE (58.5% active; 41.5% in histological remission) while 87 had non-EoE dysphagia (NED). Characteristics in Table 1. Absolute eosinophil count (AEC) of active EoE was significantly higher than NED (335 vs 90/mm3; p<0.001), and so was eosinophil percentage (4.6% vs 1.1%; p<0.001), and median lymphocyte percentage (30 vs 27%; p<0.001). ROC curve analysis showed that a cut-off of 155 eosinophils/mm3 had an AUC of 0.85, with 71% specificity and 87% sensitivity for the identification of EoE among patients with dysphagia (Figure 1a). Other ROC analyses on the diagnosis of EoE reported in Table 2. With regards to disease monitoring, only eosinophil counts differed significantly between EoE and NED. Median AEC of active EoE was higher than EoE in remission (335 vs 200/mm3; p<0.01), and so was eosinophil percentage (4.6 vs 1.4%; p<0.001) (Table 3). Based on ROC analysis, a cut-off of 325 eosinophils/mm3 had and AUC of 0.70 for the identification of histological remission in EoE, with a specificity of 52.7%% and sensitivity of 82.3% (Figure 1b) (Table 3). There was modest positive correlation between AEC and the EREFS with Spearman’s Rho of 0.4 (p<0.0001), but there was no correlation between AEC and DSQ scores (Rho= -0.01; p=0.9).

Conclusion

Our results show that the AEC in peripheral blood has good accuracy for the diagnosis of EoE in patients with dysphagia and moderate accuracy for monitoring histological disease activity. In addition, AEC was modestly correlated with endoscopic disease activity (EREFS score) but not with symptoms.

Introduction

Aspiration Pneumonia is a well described complication of upper digestive endoscopy. However, limited data are available on incidence, risk factors and clinical consequences of post- Endoscopic retrograde cholangiopancreatography (ERCP) aspiration pneumonia (pEP).

Aims & Methods

All consecutive ERCPs performed under anesthesiologist-administered sedation at the Endoscopy Unit of the University of Verona between April 1st 2022 and August 31st 2024 were retrospectively evaluated. Demographical, clinical and endoscopic data were collected.

Results

One-thousand-one-hundred-forty consecutive ERCPs were included. Main indication was malignant biliary stricture and patient’s mean age was 68±13.9 years. Overall incidence of pEP was 2.7%. American Society of Anesthesiologists (ASA) score, presence of active cholangitis before ERCP and performance of endoscopic ultrasound (EUS) and ERCP in the same sedation session were significantly associated to higher risk of pEP at both univariable and multivariable analysis. pEP was an independent risk factor for post-ERCP 30-days-mortality and for prolonged hospital stay.

Conclusion

pEP is a relatively frequent adverse event after ERCP. In patent with high ASA score, active cholangitis and scheduled EUS and ERCP in the same sedation session, preventive medical and/or anesthesiological strategies might be considered. Additional prospective studies are needed to confirm these data.
