Usage of PCI and long-term cardiovascular risk in post-myocardial infarction patients: a nationwide registry cohort study from Finland

Background: Despite currently available treatments, the burden of myocardial infarction (MI) morbidity and mortality remains prominent. The aim of this was to investigate the risk of developing subsequent cardiovascular events in MI patients.Methods: This was an observational, retrospective cohort database linkage study using patient level data from Finland. Cox proportional hazards models were used to assess the association of risk between the preselected covariates and incidence of specific outcomes. The primary endpoints were new MI, stroke, cardiovascular mortality and overall mortality.Results: Finnish adult MI patients alive 7 days after discharge in 2009-2012 were included. The study cohort consisted of 32,909 MI patients, of whom 25,875 (79%) survived 12 months without subsequent MI or stroke. ST-elevation MI (STEMI) was associated with lower risk of subsequent MI and overall mortality compared to non-STEMI patients. Percutaneous coronary intervention (PCI) was used two times more often in STEMI patients, but patients with prior stroke were more than two times less likely to have PCI. Dementia/Alzheimer's disease decreased the use of PCI as much as age over 85 years. Female sex was an independent factor for not undergoing PCI (OR 0.75, PConclusions: Risk of cardiovascular events and mortality after MI increases steeply with age. Although at higher risk, aging patients and those with cardiovascular comorbidities are less likely to receive PCI after MI. Female sex is associated with better survival after MI regardless of less intensive treatment in women.</div

Concomitant use of drugs known to cause interactions with oral antiplatelets—polypharmacy in acute coronary syndrome outpatients in Finland

Purpose: Use of oral antiplatelets (OAPs) is essential for preventing thrombotic events in patients with acute coronary syndrome (ACS). Effects of clopidogrel, prasugrel, and ticagrelor may be enhanced due to pharmacodynamic interactions, but as CYP substrates, they are prone to pharmacokinetic interactions too. The aim was to study polypharmacy in ACS patients following hospital discharge.Methods: This observational drug utilization study linked patient-level data from nationwide registers. The study population consisted of adult ACS patients discharged from Finnish hospitals in 2009–2013. Logistic regression was used to model the probability of drug-drug interactions with odd ratios for predefined predictors such as age, gender, and ACS type.Results: In the cohort of 54,416 ACS patients, 91% of those treated with OAP received clopidogrel. Of clopidogrel-treated patients, 12% purchased warfarin at least once while on clopidogrel treatment. Old age, male sex, ST-elevation myocardial infarction as index event, and a history of previous ACS events were associated with an increased risk of warfarin-OAP interaction (p Conclusions: Warfarin and ibuprofen were the most commonly used concomitant medications causing pharmacodynamic interactions and potentially increasing the risk of bleeding in OAP-treated patients. Esomeprazole and omeprazole were used in clopidogrel-treated patients although there are alternatives available for gastric protection.</p

Biosimilars Would Reduce Health Care Costs But Are Yet Poorly Known &ndash; Patient Survey Study Among Biological Medicine Users

Mari Pölkki, Tuire Prami Oriola, Expert Services, Espoo, FinlandCorrespondence: Tuire Prami, Oriola Finland Oy, Orionintie 5, 02200 Espoo, Finland, Tel +358505468459, Email [email protected]: From the beginning of the year 2024, gradually implemented amendment to the Medicines Act will enable interchange of biological medicines in pharmacies in Finland. The legislative change aims to reduce health care costs.Methods: Opinions of the biological medicine users regarding substitution in pharmacies and knowledge about biological medicines were determined by a patient survey in community pharmacies and via patient organizations in Finland.Results: In total, 199 users of biological medicines responded to the survey. The respondents did not always know which product they were using, an originator or a biosimilar. This was more prominent among patients with biosimilars determined according to brand names. The more recently the biological medicine had been prescribed, the more likely a biosimilar was in use. Only about 40% of the respondents would enable pharmacies to substitute their biological medicine to a lower cost product. The most common obstacle to the idea of interchange in pharmacies was that the respondents wanted to keep the product the doctor had prescribed for them. In general, biosimilar users were more accepting towards possible interchange than originator users.Conclusion: Although the most recent treatments appear to be initiated with biosimilars, interchange in pharmacies could enable an efficient way to lower health care costs. However, guidance and awareness regarding biosimilars and biological medicines in general would improve patients’ willingness towards the change, but also help pharmacists and prescribing doctors in their meaningful role.Plain Language Summary: The use of biological medicines and the costs thereafter are rapidly growing.In Finland, switching between an originator and a biosimilar currently requires doctor’s prescription, but interchange in pharmacies will be possible in the beginning of year 2024.Due to notable differences in prices between biological medicines, active switching to lower cost products in pharmacies would restrain health care costs remarkably.Oriola Expert Services ran a survey with an electronic questionnaire among patients using biological medicines.Survey data were collected in pharmacies and via patient organizations.Oriola research team found out that patients do not generally know the differences between biological medicines, and if they are using an originator or a biosimilar.Despite the upcoming pharmacy substitution, future cost savings rely on decisions made by doctors at the time of prescribing biological medication.To ensure patient compliance, sufficient patient information about biosimilars is required.Keywords: biological medicine, originator, biosimilar, reference product, interchang

Metal-ion transporter SLC39A8 is required for brain manganese uptake and accumulation

Manganese (Mn) is an essential nutrient, but is toxic in excess. Whole-body Mn levels are regulated in part by the metal-ion influx transporter SLC39A8, which plays an essential role in the liver by reclaiming Mn from bile. Physiological roles of SLC39A8 in Mn homeostasis in other tissues, however, remain largely unknown. To screen for extrahepatic requirements for SLC39A8 in tissue Mn homeostasis, we crossed Slc39a8-inducible global-KO (Slc39a8 iKO) mice with Slc39a14 KO mice, which display markedly elevated blood and tissue Mn levels. Tissues were then analyzed by inductively coupled plasma-mass spectrometry to determine levels of Mn. Although Slc39a14 KO; Slc39a8 iKO mice exhibited systemic hypermanganesemia and increased Mn loading in the bone and kidney due to Slc39a14 deficiency, we show Mn loading was markedly decreased in the brains of these animals, suggesting a role for SLC39A8 in brain Mn accumulation. Levels of other divalent metals in the brain were unaffected, indicating a specific effect of SLC39A8 on Mn. In vivo radiotracer studies using 54Mn in Slc39a8 iKO mice revealed that SLC39A8 is required for Mn uptake by the brain, but not most other tissues. Furthermore, decreased 54Mn uptake in the brains of Slc39a8 iKO mice was associated with efficient inactivation of Slc39a8 in isolated brain microvessels but not in isolated choroid plexus, suggesting SLC39A8 mediates brain Mn uptake via the blood–brain barrier. These findings establish SLC39A8 as a candidate therapeutic target for mitigating Mn uptake and accumulation in the brain, the primary organ of Mn toxicity. © 2023 The AuthorsOpen access journalThis item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.
