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.

Introduction

Chronic liver disease remains one of the most common causes for hospital admission and is associated with high morbidity and mortality rates. Timely and adequate management within the first 24 hours is crucial for improving clinical outcomes in cases of decompensated cirrhosis. This study aimed to evaluate the impact of implementing a care bundle checklist during the first 24 hours of hospital admission on management and outcomes of decompensated cirrhosis.

Aims & Methods

We developed an adapted care bundle (based on the BSG/BASL care bundle, AASLD quality measures proposal, Baveno VII consensus, and EASL guidelines) and compared two patient groups from two Portuguese hospital centers: Group-A (retrospective, pre-care bundle implementation) and Group-B (prospective, post-care bundle implementation).

Results

A total of 224 patients (Group-A: 148; Group-B: 76) were included. More than one decompensation was observed in 118 patients (52.7%), and 69 patients (30.8%) were experiencing their index hospitalization for liver decompensation. Regarding etiology, alcoholic liver disease was the most common (n=200; 89.3%). The groups were similar in terms of gender, age, length of hospital stay, and Child-Pugh and MELD-Na scores at admission. The most common decompensations were gastrointestinal bleeding (n=91; 40.6%), ascites (n=75; 33.5%), and hepatic encephalopathy (n=72; 32.1%). Group B was more likely to present with multiple decompensations at admission and exhibited significantly higher rates of acute kidney injury, hepatocellular carcinoma, acute-on-chronic liver failure, and portal vein thrombosis (p<0.05). Following care bundle implementation, we found significant improvements in patient care. At admission, patients were significantly more likely to undergo urine and blood cultures, chest X-ray, and abdominal ultrasound (p<0.05), receive diagnostic paracentesis (p<0.05), and have an accurate alcohol history documented (p=0.04). During admission, Group-B was significantly more likely to be prescribed lactulose for encephalopathy prophylaxis, vasopressor therapy for gastrointestinal bleeding, and venous thromboembolism prophylaxis, as well as undergo nutritional assessment (p<0.05). While in-hospital mortality rates were similar (4.7% vs. 5.3%; p=1), 6-week mortality rates (8.8% vs. 3.9%; p=0.01) and 3-month readmission rates (31.1% vs. 15.8%; p=0.02) were significantly lower in the post-intervention cohort.

Conclusion

The implementation of a standardized care bundle was associated with higher rates of appropriate investigation and treatment within the first 24 hours of hospital admission and improved patient outcomes, reducing 6-week mortality and 3-month readmission rates.

Clinical Case Summary

Introduction: Rituximab, a monoclonal anti-CD20 antibody, is widely used for treating hematologic malignancies and autoimmune disorders due to its B-cell depleting action. While gastrointestinal side effects like diarrhea are seen in up to 15% of patients, these are typically mild and self-limiting. Severe colitis is a rare but increasingly recognized complication.
Case Description: A 76-year-old diabetic male with a history of ACS (post-PTCA in 2021) presented with 2 months history of generalized abdominal pain, watery diarrhea (6–7 episodes/day), and weight loss. He had a history of follicular lymphoma diagnosed 4 years prior, treated with 6 cycles of CHOP-R followed by rituximab maintenance (375 mg/m² every 3 months). Symptoms began after the 6th maintenance dose.Physical exam revealed mild pallor;abdomen was soft, nontender. Labs showed normocytic anemia and mild neutrophilic leukocytosis. Stool tests were negative for common pathogens, including C. difficile. The patient was planned for a Colonoscopy, which revealed ulcers over the ileocecal valve and rectal erosions. Biopsies showed mixed inflammatory infiltrates, cryptitis, crypt abscesses, and crypt rupture, consistent with severe active ileocolitis. AFB culture and GeneXpert were negative for tuberculosis.The patient was started on oral mesalamine (500 mg TID) along with Rifaximin(400mg) BD for 2 weeks, showing marked clinical improvement.
Discussion: Rituximab-induced colitis is rare and poorly understood. It may result from disruption of mucosal immunoregulation due to B-cell depletion, leading to T-cell-mediated inflammation. Histology may resemble patterns seen in GVHD or autoimmune enteropathy. Most cases resolve with supportive care and discontinuation of the drug; however, some, like this case, may require treatment in the form of 5ASA, or steroids.There is no previous data on the use of rifaximin in such cases. Differentiating drug-induced IBD from primary IBD remains a diagnostic challenge.

References

There is limited evidence in the literature establishing a definitive association between rituximab therapy and the onset of colitis. However, emerging hypotheses suggest that rituximab-induced depletion of peripheral CD19+ B cells and colonic CD20+ lymphoid aggregates may disrupt mucosal immune homeostasis, thereby contributing to structural alterations in the intestinal architecture and promoting inflammation.
The role of the gut microbiota in the pathogenesis and persistence of mucosal inflammation in inflammatory bowel disease (IBD) provides a rationale for the therapeutic use of antibiotics in selected cases. While systemic antibiotics such as ciprofloxacin and metronidazole have demonstrated clinical efficacy in IBD management, their utility may be limited in drug-induced colitis due to the potential for systemic adverse effects.
In contrast, rifaximin, a non-systemic, presents a favorable safety profile and has shown promise as a therapeutic option in both idiopathic and drug-induced enterocolitis. Its targeted antimicrobial activity within the gastrointestinal tract, combined with minimal systemic exposure, renders it an attractive alternative. However, further prospective, randomized studies are warranted to substantiate its efficacy and long-term safety in this context.

Introduction

Hepatic encephalopathy (HE) after Transjugular Intrahepatic Portosystemic Shunt (TIPS) affect 35-50% of patients. The use of prophylactic agents (Lactulose and Rifaximin) to prevent post-TIPS HE remains controversial and currently not recommended by professional guidelines. Our aim was to assess real world practice and identify potential predictors for post-TIPS HE and benefit from post-TIPS prophylaxis.

Aims & Methods

Retrospective cohort study of patients undergoing TIPS at the Tel-Aviv Medical Center (2016-2024). The primary outcome was overt HE, with secondary outcomes of liver transplantation (LT) and mortality.

Results

Seventy-nine patients underwent TIPS, median age was 60 years and 52% were male. Primary liver disease was metabolic dysfunction-associated steatohepatitis (MASH) in 34%, viral (20%), and alcohol-related liver disease (ALD) (16.5%). Indications for TIPS were variceal bleeding (52%) and refractory ascites (38%). Prior to the procedure 31% had ≥ 1 episodes of HE, 21.5% were treated with Lactulose and/or Rifaximin, and 58% were on betablocker treatment. At the time of the procedure, the patient's Child-Pugh score was A/B/C in 19%/66%/11% respectively, with a median MELD-Na of 10.9. Median follow up was 22.75 months. Overall, 22 patients died during follow-up and 8 underwent liver transplantation. 45 patients (57%) developed post-TIPS HE, 60% of them during the first three months. Early post-TIPS HE treatment was given to 49%: 10% Lactulose, 5% Rifaximin, and 34% both. Among those patients, 44% were previously (pre-TIPS) on HE treatment. Development of HE was not predicted by pre-or post-TIPS MELD-Na or Child-Pugh score, TIPS diameter, postTIPS gradient, or post-procedure ammonia levels. Rates of HE also did not differ according to initial prophylaxis treatment (59% with treatment, 56% without, p=1). Pre-TIPS AST and albumin were associated with post-TIPS HE (36.6U/L vs. 60.44 U/L, p=0.03; 34.6g/dl vs. 31.8g/dl, p = 0.05). Prior beta-blocker treatment was associated with post-TIPS HE (14% vs 32%, p = 0.01) but not varices as the indication for TIPS. Mortality rate was not affected by the occurrence of post-TIPS HE (28% among those who developed HE vs. 26% among those who didn't, p = 1).

Conclusion

Early post-TIPS preventive treatment was mostly given to patients previously treated with Lactulose/Rifaximin, however it did not affect the rate of post-TIPS HE. Development of HE did not increase mortality.
