ABSTRACT
AIMS: Knowledge on the prescriptive practice of direct oral anticoagulants (DOACs) in older subjects with atrial fibrillation (AF) hospitalized in acute medical wards is limited. This study aimed to evaluate the prevalence and appropriateness of DOAC prescriptions in hospitalized older subjects with AF, discharged from acute medical wards. METHODS: We analysed a cohort of 609 subjects with AF, aged ≥65 years (mean age 85 years) enrolled from 39 geriatric and nephrology wards in Italy. DOAC prescriptive appropriateness was evaluated according to the summary of product characteristics (smPC), 2019 Beers and STOPP criteria, and drug-drug interactions (DDIs). RESULTS: At hospital discharge, 33% of patients with AF were prescribed with DOAC, 26% with vitamin-K antagonist, while 41% did not receive any anticoagulant. Among subjects on DOAC therapy, 31% presented a violation of the smPC criteria (mainly underdosage-17%), while 48% and 18% presented a Beers/STOPP inappropriate prescription, or a DDI, respectively. Older age, lower body mass index (BMI), cancer and higher estimated glomerular filtration rate (eGFR) were independently associated with DOAC underdosage or missed prescription (age: adjusted odds ratio [aOR] 1.06, 95% confidence interval [95% CI] 1.00-1.12 for underdosage; eGFR: aOR 1.04, 95% CI 1.02-1.07 for underdosage; BMI: aOR 0.95, 95% CI 0.91-0.99 for missed prescription; cancer: aOR 1.93, 95% CI 1.19-3.13 for missed prescription). CONCLUSIONS: This study showed a suboptimal DOAC prescriptive practice in older in-patients, with frequent missed prescription and DOAC underdosage. Contrary to current recommendations, physicians appear overly concerned by bleeding risk in real-life older and frailer subjects. Strategies should be developed to promote appropriate DOAC prescription in the hospital setting.

Patients suffering from different forms of acute hepatic porphyria present a high risk of primary liver cancer, specifically hepatocellular carcinoma and cholangiocarcinoma, determined by the activity of the disease even though an exact mechanism of carcinogenesis has not been recognized yet. Here, we present the clinical case of a 72-year-old woman who, approximately 29 years after the diagnosis of acute intermittent porphyria, presented with intrahepatic cholangiocarcinoma with a histological diagnosis of adenocarcinoma starting from the biliary-pancreatic ducts, which was diagnosed during the clinical and anatomopathological evaluation of a pathological fracture of the femur.
