Drug-induced acute pancreatitis (AP) is uncommon and pancreatic involvement due to immune checkpoint inhibitors (ICI) in published reports relied on the National Cancer Institute's (NCI) Common Terminology Criteria for Adverse Events (CTCAE). CTCAE definition of AP differs from the revised Atlanta classification diagnostic criteria. This study aims to classify the spectrum of pancreatic involvement in patients receiving ICI therapy into categories built on the revised Atlanta classification.A retrospective cohort study of cancer patients receiving cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) and programmed cell death protein 1 (PD-1) inhibitors between 2011 and 2020. Pancreas-specific immune-related adverse events (irAEs) were categorized into AP and pancreatic injury.Forty-seven patients on ICI therapy met selection criteria. Twenty patients (43%) had AP, while 27 (57%) had pancreatic injury. Fifteen patients (75%) developed mild AP. Five patients progressed to pancreatic atrophy, and two patients (4%) developed exocrine pancreatic insufficiency. In both groups, most patients received nivolumab therapy (70% vs. 67%, p = 0.08) with no difference in mean number of nivolumab doses (9 vs. 10, p = 0.69). There was no correlation between the mean number of nivolumab or pembrolizumab doses and AP events (OR 0.94, p = 0.26, and OR 0.98, p = 0.86), but the duration of ICI therapy was significantly related to pancreatic atrophy (OR 1.01, p = 0.05; 95% CI 1.00-1.02).Based on the novel classification, majority of pancreatic irAEs were classified as asymptomatic pancreatic injury but with some risk of pancreatic atrophy. This classification can help in assessing patterns of pancreatic involvement, pathogenesis, and treatment decisions.

Pancreatic ductal adenocarcinoma (PDAC) is a lethal disease with poor prognosis, leading to significant cancer-related mortality and an overall five-year survival rate of about nine percent. Acute and chronic pancreatitis have been associated with PDAC through common risk factors based on multiple epidemiological studies. Acute pancreatitis (AP) might be one of the earliest manifestations of PDAC, but evolving chronic pancreatitis (CP) following recurrent bouts of AP has been proposed as a risk factor for cancer development in the setting of persistent inflammation and ongoing exposure to carcinogens. This review aims to highlight the evidence supporting the relationship between acute and chronic pancreatitis with PDAC.

Background: The proportion of patients with advanced chronic kidney disease (CKD) initiating dialysis therapy at a higher glomerular filtration rate (GFR) has increased during the past decade. Recent data suggest that higher GFR may be associated with increased mortality. Study Design: A meta-analysis of cohort studies and trials. Setting & Population: Patients with advanced CKD. Selection Criteria for Studies: We performed a systematic literature search in MEDLINE, Cochrane Central Register of Controlled Trials, ClinicalTrials.gov, American Society of Nephrology abstracts, and bibliographies of retrieved articles to identify studies reporting on GFR at dialysis therapy initiation and mortality. Predictor: Estimated or calculated GFR at dialysis therapy initiation. Outcome: Pooled adjusted hazard ratio (HR) of continuous GFR for all-cause mortality. Results: 16 cohort studies and 1 randomized controlled trial were identified (n = 1,081,116). By meta-analysis restricted to 15 cohorts (n = 1,079,917), higher GFR at dialysis therapy initiation was associated with a higher pooled adjusted HR for all-cause mortality (1.04; 95% CI, 1.03-1.05; P
