Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal cancers with patients having unresectable or metastatic disease at diagnosis, with poor prognosis and very short survival. Given that genetic variation within autophagy-related genes influences autophagic flux and susceptibility to solid cancers, we decided to investigate whether 55,583 single nucleotide polymorphisms (SNPs) within 234 autophagy-related genes could influence the risk of developing PDAC in three large independent cohorts of European ancestry including 12,754 PDAC cases and 324,926 controls. The meta-analysis of these populations identified, for the first time, the association of the BID variant with an increased risk of developing the disease (OR = 1.

Finite nucleos(t)ide-analogue therapy for functional cure in HBeAg-negative chronic hepatitis B: recent development in the paradigm shift.

Hepatology

September 2024

Academic Department of Gastroenterology, Medical School of National and Kapodistrian University of Athens, General Hospital of Athens "Laiko", Athens, Greece.

Long-term nucleos(t)ide analogue (Nuc) therapy in chronic hepatitis B (CHB) may lead to hepatitis B virus (HBV) suppression, alanine aminotransferase (ALT) normalization, improvement of histological lesions, and prevention of liver disease progression, but rarely achieve HBsAg loss, the hallmark of functional cure. HBeAg-negative CHB patients have often been recommended to continue Nuc therapy until HBsAg loss, which usually means indefinitely. However, long-term/life-long Nuc therapy is associated with increasing costs and concerns of adverse outcomes subsequent to poor adherence and/or self-cessation/loss-to-follow-up.

Safe outpatient discharge after gastrointestinal endoscopy with sedation and analgesia: a systematic literature review.

Ann Gastroenterol

July 2024

Department of Gastroenterology, "Konstantopoulio-Patision" General Hospital of Nea Ionia, Athens, Greece (Marianna Spinou, Eleni Kyvelou, Giorgos Aggelopoulos, Antonia Panagaki, Magdalini Manti, Paraskevas Gkolfakis, Nikoletta Mathou, Athanasios Giannakopoulos, Konstantina D. Paraskeva, Georgios Tziatzios).

Sedation and analgesia during gastrointestinal (GI) endoscopy increase procedural quality, contributing at the same time to greater patient satisfaction and willingness to undergo the procedure. Although sedation use has been optimized by the advent of efficacious and safe medications, data regarding the minimal criteria for discharge after outpatient endoscopy remain scant. Moreover, the time of discharge after endoscopy can be highly variable, depending not only on the type of procedure and anesthesia administered, but also on postprocedural complications and the patient's comorbidities.

Article Synopsis
  • Patients with inflammatory bowel disease (IBD) are at a higher risk for hepatitis B virus (HBV) and should ideally be vaccinated; this study evaluated the effectiveness of HBV vaccination among these patients and factors influencing their immune response.
  • A total of 409 IBD patients were studied, with 66.7% responding to the initial vaccination; those with lower body mass index had better immune responses, while certain disease types and treatments negatively impacted response rates.
  • Among nonresponders receiving revaccination, 58.3% achieved protective antibody levels, indicating that enhanced revaccination could benefit about half of these patients despite overall lower responsiveness compared to the general population.

Academic Department of Gastroenterology, Medical School of National and Kapodistrian University of Athens, General Hospital of Athens 'Laiko', Athens, Greece.

Introduction: Dysphagia and bolus impaction are the cardinal manifestations of eosinophilic esophagitis (EoE). Esophageal biopsy sampling is mandatory for EoE diagnosis, data though suggest that clinician do not always obtain biopsies from patients with cardinal EoE symptoms during upper gastrointestinal endoscopy even if no other entity than EoE can explain patients symptoms. We aimed to search for the esophageal biopsy procurement rate as also for factors that drive clinicians to obtain esophageal biopsies among patients with cardinal EoE symptoms.

Transjugular intrahepatic portosystemic shunt for recompensating decompensated cirrhosis?

World J Gastroenterol

May 2024

Academic Department of Gastroenterology and Hepatology, Medical School of National and Kapodistrian University of Athens, General Hospital of Athens "Laiko", Athens 11527, Greece.

Transjugular intrahepatic portosystemic shunt (TIPS) is a medical procedure that has been used to manage variceal bleeding and ascites in patients with cirrhosis. It can prevent further decompensation and improve the survival of high-risk decompensated patients. Recent research indicates that TIPS could increase the possibility of recompensation of decompensated cirrhosis when it is combined with adequate suppression of the causative factor of liver disease.

Article Synopsis
  • The study evaluated the accuracy of Agile scores (Agile 3+ and Agile 4) for diagnosing advanced liver fibrosis and cirrhosis in patients with metabolic dysfunction-associated steatotic liver disease (MASLD), alcohol-related liver disease (ALD), and chronic hepatitis B or C (CHB/C).
  • It included 4,243 patients and found that Agile scores had diagnostic accuracy comparable to liver stiffness measurements (LSM) in MASLD and ALD, but performed less effectively in CHB/C.
  • The results suggest that using Agile scores alongside existing biomarkers like FIB-4 can improve diagnosis by reducing indeterminate results and enhancing specificity for advanced liver conditions.
