Prevalence of Drug Prescriptions and Potential Safety in Patients with Cirrhosis: A Retrospective Real-World Study.

ABSTRACT: INTRODUCTION:Patients with cirrhosis are at risk for adverse drug reactions (ADRs) due to altered pharmacokinetics and pharmacodynamics. We aimed to determine the prevalence of drug prescriptions and the potential safety of these prescriptions in a real-world cohort of patients with cirrhosis. METHODS:This was a retrospective cohort study based on linked real-world data from the Out-patient Pharmacy Database and the Hospitalisation Database of the PHARMO Database Network. Patients with a diagnosis of cirrhosis between January 1998 and December 2015 were included. Follow-up ended when the patient underwent a liver transplant, died, transferred out of the database, or on 31 December 2015. Prescription data were derived from a community pharmacy database and were compared with our previously developed safety recommendations for 209 drugs. RESULTS:In total, 5618 patients were included and followed for a median of 3 years (interquartile range [IQR] 1-7). In the first year after the diagnosis, patients used a median of nine drugs (IQR 5-14), with proton pump inhibitors (prevalence 53.9%), aldosterone antagonists (43.6%), and sulfonamide diuretics (41.3%) being the most commonly used drug groups. Almost half (48.3%) of 102,927 prescriptions consisted of drugs with a safety recommendation. The prevalence of potentially unsafe drug use was 60.0% during the total follow-up. Three nonsteroidal anti-inflammatory drugs (NSAIDs) were among the five most commonly used potentially unsafe drugs. CONCLUSIONS:Patients with cirrhosis use a large number of drugs. Almost two-thirds of patients in our cohort used potentially unsafe drugs. To prevent ADRs in these frail patients, personalised pharmacotherapy is necessary.

Project description:BackgroundA recent phase II trial reported prolonged survival in patients with advanced biliary tract cancer (BTC) following treatment with nab-paclitaxel plus gemcitabine-cisplatin (Gem/Cis/nab-P). We aimed to evaluate the clinical outcomes of Gem/Cis/nab-P in Asian patients with advanced BTC in a real-world setting.MethodsWe reviewed the data of patients who received Gem/Cis/nab-P for the management of advanced BTC between September 2019 and April 2021 at four institutes in Korea. Patients were classified into the Gem/Cis/nab-P and nab-P addition groups depending on the starting point of nab-P administration.ResultsA total of 178 patients treated with Gem/Cis/nab-P were included in the study. Of these, 43.8% had intrahepatic cholangiocarcinoma (CCA), 34.8% had extrahepatic CCA, and 21.3% had gall bladder cancer. A total of 117 (65.7%) patients received Gem/Cis/nab-P as the first-line treatment, while 61 (34.3%) were treated with gemcitabine-cisplatin-based chemotherapy followed by nab-P addition. The objective response rate (ORR) and disease control rate in all patients were 42.1% and 84.8%, respectively. The ORR in the Gem/Cis/nab-P group was 47.9%, while that in the nab-P addition group was 31.1%. The median progression-free survival and overall survival were 8.5 months [95% confidence interval (CI), 6.9-10.1] and 14.6 months (95% CI, 10.2-19.0), respectively. In patients who received Gem/Cis/nab-P as initial treatment, the median PFS was 9.4 months (95% CI, 7.9-10.9) and the median OS was not-reached (95% CI, not available). Anemia (n = 42, 23.6%), neutropenia (n = 40, 22.5%), and thrombocytopenia (n = 16, 9.0%) were the most common grade 3-4 toxicities. A total of 20 patients (11.2%) had conversions from unresectable to resectable disease and underwent surgery with curative intent.ConclusionGem/Cis/nab-P showed favorable real-life efficacy and safety outcomes in Korean patients with advanced BTC, which was consistent with the phase II trial outcomes.

Project description:Purpose:We conducted this study to assess the real-world prevalence, nature, predictors, and clinical necessity of apixaban pharmacokinetic (PK) and pharmacodynamic (PD) drug interactions in patients with non-valvular atrial fibrillation (NVAF) at a tertiary medical institution in Saudi Arabia. Patients and Methods:An observational retrospective cohort analysis was conducted in adult patients diagnosed with NVAF receiving apixaban for stroke prevention from the period of June 2015 to May 2019. Results:Of the 1271 patients included in the analysis, 611 (48.1%) patients had potential PD- or PK-drug interactions with apixaban. Of those, 490 (38.6%) patients had potential PD drug-drug interactions (DDIs) and 121 (9.5%) patients had potential PK-DDIs. PD-DDIs with apixaban were mainly with antiplatelet therapy followed by non-steroidal anti-inflammatory drugs and antidepressants. PK-DDIs with apixaban were mainly with combined P-gp/CYP3A4 inhibitors or inducers. History of minor bleeding was positively correlated with PD-DDIs with apixaban, ß coefficient = 0.455 (OR 1.58; 95% CI 1.01-2.45); p<0.05. History of acute coronary syndrome was positively correlated with PD-DDIs with apixaban, ß coefficient = 0.515 (OR 1.60; 95% CI 1.36-1.99); p<0.05. History of heart failure was positively correlated with PK-DDIs with apixaban, ß coefficient = 0.459 (OR 1.58; 95% CI 1.07-2.35); p<0.05. Almost 15% of the included patients had no clinical indication to receive the potential interacting drug with apixaban and about 20% of them were assuming an inappropriate apixaban dose according to the product package insert. Conclusion:Pharmacodynamics and pharmacokinetics interactions are common in more than half of the patients with NVAF receiving apixaban for stroke prevention in this real-world analysis. Some of these interacting medications are not indicated. Drug-drug interactions should always be considered and monitored with apixaban with a regular assessment of the need for any interacting medication.
