Introduction: Chronic pancreatitis (CP) can lead to malnutrition, an established risk factor for low bone mineral density (BMD) and fractures. This study aims determine the prevalence of BMD, assess fracture incidence explore factors fractures in patients with CP. Patients methods: We performed a retrospective analysis all treated CP at Karolinska University Hospital between January 1999 December 2020. Electronic medical records were retrieved demographic, laboratory clinical data. subjected...
Introduction: Chronic pancreatitis (CP) is a long-standing progressive inflammation of the pancreas, which can lead to variety vascular complications, such as splanchnic venous thrombosis (VT) and arterial pseudoaneurysm (PA). There lack studies on complications in Scandinavian countries. Methods: We performed retrospective analysis medical records patients with CP identified from Karolinska University Hospital database between 2003 2018. A total 394 definite were included study. Results: 33...
Abstract In pancreatic ductal adenocarcinoma, the infiltration of CD8+ T cells within tumor microenvironment correlates with a favorable prognosis. However, significant proportion tumor-infiltrating become trapped desmoplastic stroma and lack reactivity. Here, we explored different T-cell subsets in tumors adjacent tissues. We identified subset cells, double positive (DP) for CD39 CD103 tumors, which has recently been described to display reactivity other types solid tumors. Interestingly,...
Background Paraduodenal pancreatitis (PDP) is a particular form of chronic (CP) occurring in and around the duodenal wall. Despite its low prevalence, this rare condition presents significant challenge clinical practice.Methods We retrospectively analysed electronic medical charts all patients with diagnosis identified those PDP, between January 1999 December 2020.Results There were 35 diagnosed PDP (86% males 14% females); median age 56 ± 11 (range 38–80). Alcohol overconsumption was...
Introduction Although abdominal pain is the most prevalent and disabling symptom in patients with chronic pancreatitis (CP), there are also who have painless CP.Patients methods We performed a retrospective analysis of diagnosis CP. A total 279 definite CP completed demographic clinical data were included final analysis.Results There 75 (26.9%) These had significantly higher mean age at diagnosis, 61.7 years, than 52.5 years (p < 0.001). Painless painful similar rates diabetes mellitus (DM)...
