Hepatocellular carcinoma (HCC) comprises 75 to 85% of all primary liver cancers. Current guidelines recommend a biannual HCC surveillance using ultrasound (US) for high-risk patients. However, due to its low sensitivity for detection of early-stage HCC lesions, there is an urgency for more sensitive surveillance tools.

Rationale And Objectives: Distinguishing malignant from benign liver lesions based on magnetic resonance imaging (MRI) is an important but often challenging task, especially in noncirrhotic livers. We developed and externally validated a radiomics model to quantitatively assess T2-weighted MRI to distinguish the most common malignant and benign primary solid liver lesions in noncirrhotic livers.

Materials And Methods: Data sets were retrospectively collected from three tertiary referral centers (A, B, and C) between 2002 and 2018.

Background & Aims: Patients with chronic hepatitis B (CHB) are at increased risk of hepatocellular carcinoma and (liver-related) mortality. In addition to hepatitis B-related factors, metabolic comorbidities may contribute to the progression of fibrosis. Therefore, we studied the association between metabolic comorbidities and adverse clinical outcomes in patients with CHB.

Background & Aims: Increased serum IgG and autoantibodies suggest involvement of B cells in autoimmune hepatitis (AIH). The aim of this study was to assess levels of B cell activating factor of the tumour necrosis family (BAFF), IL-21, and circulating B cell populations in AIH and correlate these to treatment response.

Methods: BAFF and IL-21 levels were determined in 66 patients with AIH before treatment and 10 healthy controls.

As pegylated interferon alpha (PEG-IFN-α) is increasingly used in combination regimens of novel drugs, we aimed to characterize ALT flares and their relationship with serum HBsAg and HBV RNA kinetics in a large combined cohort of chronic hepatitis B (CHB) patients on PEG-IFN-α-based therapy. In this post hoc analysis of four international randomized trials, 269/130/124/128 patients on PEG-IFN-α monotherapy, PEG-IFN-α plus nucleos(t)ide analogue (NA) de novo combination, PEG-IFN-α add-on to NA or NA monotherapy were included, respectively. A flare was defined as an episode of ALT ≥5 × ULN.

Background: Treatment with immunosuppressive drugs (IS) after transplantation is accompanied by severe side effects. A limited number of studies have investigated the effect of IS withdrawal on IS-related comorbidities after liver transplantation (LTx) and the results are contradictory.

Patients And Methods: We determined in a retrospective case-control study the clinical effects of complete IS withdrawal in operationally tolerant (TOL) LTx recipients who discontinued IS 10.

Improved quality of life in immunocompromised patients opens travel opportunities, but administering the yellow fever (YF) vaccine is often contraindicated. We advocate re-evaluating this position for immunocompromised patients who travel frequently or who are migrating to regions in which YF is endemic.

Background: A reduction in skeletal muscle mass (sarcopenia) independently predicts poor survival in patients with hepatocellular carcinoma (HCC) undergoing treatment with curative intent. Whether this is due to an increased risk of recurrence and disease specific death, or due to an increased risk of postoperative morbidity and mortality is currently unclear. In this study, we investigate the association between sarcopenia and death in a cohort of HCC patients undergoing treatment with curative intent.

Article Synopsis
  • * A study involving 57 patients revealed that while they face numerous issues, the most common are related to physical health, emotional well-being, and loss of autonomy.
  • * Many patients express a need for professional care, particularly for physical and emotional struggles, but report receiving inadequate support for challenges like fatigue and fear, suggesting that individualized care strategies should be prioritized.

Background & Aims: We aimed to assess the association between the patatin-like phospholipase domain-containing-3 (PNPLA3) I148M polymorphism, liver histology and long-term outcome in chronic hepatitis B (CHB) patients.

Methods: We enrolled 531 consecutive treatment naïve CHB patients diagnosed from 1985 to 2012 with an available liver biopsy for reassessment, and sample for genetic testing. Data on all-cause mortality and hepatocellular carcinoma (HCC) at long-term follow-up were obtained from national database registries.

Context: Upper gastrointestinal cancer is associated with a poor prognosis. The multidimensional problems of incurable patients require close monitoring and frequent support, which cannot sufficiently be provided during conventional one to two month follow-up visits to the outpatient clinic.

Objectives: To compare nurse-led follow-up at home with conventional medical follow-up in the outpatient clinic for patients with incurable primary or recurrent esophageal, pancreatic, or hepatobiliary cancer.

Traditionally, surgical resection has been the treatment of choice in many patients with hepatocellular adenoma because of the risk of rupture, hemorrhage and malignant transformation. However, some patients are not amenable for surgery due to the extensive involvement of the liver, as in patients with liver adenomatosis. We report 2 cases with liver adenomatosis in which we combined surgery with open and percutaneous radiofrequency ablation for lesions located in both lobes of the liver.

Background & Aims: Hepatocellular adenoma in pregnant women requires special considerations because of the risk of hormone induced growth and rupture. To prevent these potential lethal complications, pregnancy is either often discouraged or the surgical resection of large adenomas is recommended. It may be questioned whether it is justified to deny a young woman a pregnancy, as the biological behaviour of hepatocellular adenoma may be less threatening than presumed.

Purpose: Several malignancies have been reported to occur more often after liver transplantation. Whether this is also true for colorectal carcinoma is controversial. Our aims were 1) to compare the observed rate of colorectal carcinoma in a post-liver transplantation cohort with incidence data from the general Dutch population, and 2) to stratify for patients with and without primary sclerosing cholangitis, because primary sclerosing cholangitis is well established as a risk factor for colorectal carcinoma.

Proton pump inhibitor (PPI)-induced hypomagnesemia has been recognized since 2006. Our aim was to further characterize the clinical consequences and possible mechanisms of this electrolyte disorder using 4 cases. Two men (aged 63 and 81 years) and 2 women (aged 73 and 62 years) had been using a PPI (esomeprazole, pantoprazole, omeprazole, and rabeprazole, 20-40 mg) for 1-13 years.
