PURPOSE: Non-steroidal anti-inflammatory drugs (NSAIDs) have been associated with an increased risk of arterial thrombosis, but their effect on venous thrombotic events is less well established. The study aimed to assess the risk of symptomatic pulonary embolism (PE) in patients using NSAIDs and to evaluate any effect of type, dose, and duration of therapy
BACKGROUND: Use of platelet aggregation inhibitors and vitamin K antagonists has been associated with an increased risk of intracranial hemorrhage (ICH). Whether the use of these antithrombotic drugs is associated with an increased risk of subarachoid hemorrhage (SAH) remains unclear, especially as confounding by indication might play a role
Previous studies evaluated the association between proton pump inhibitor (PPI) use and subsequent fracture risk, but they showed ambiguous results. Therefore, the objective was to evaluate this association in a different study population. Our findigs show that there is probably no causal relationship between PPI use and hip fracture risk
We assessed several classes of serotonergic drugs in order to evaluate whether they constitute a risk factor for hospitalization for bleeding (gastrointestinal, intracranial, or in the female genital tract). A case-control study was conducted usingdata from the PHARMO record linkage system (RLS). The study population comprised 28,289 cases and 50,786 matched controls
BACKGROUND: The association between myocardial infarction (MI) and co-administration of proton pump inhibitors (PPIs) and clopidogrel remains controversial. AIM: To quantify the association between concomitant use of PPIs and clopidogrel and occurrnce of recurrent MI. METHODS: We conducted a case-control study within a cohort of acute MI patients in PHARMO Record Linkage System (1999-2008)
PURPOSE: In this proof-of-concept paper we describe the framework, process, and preliminary results of combining data from European electronic healthcare record (EHR) databases for large-scale monitoring of drug safety. METHODS: Aggregated demograpic, clinical, and prescription data from eight databases in four countries (Denmark, Italy, Netherlands, the UK) were pooled using a distributed network approach by generation of common input data followed by local aggregation through custom-built software, Jerboa((c))
BACKGROUND: Statins (inhibitors of 3-hydroxy-3-methyl-glutaryl-CoA reductase) are associated with rare but serious adverse events involving the muscle, kidney and liver. To compare the safety profile of rosuvastatin with other marketed statins, foupharmacoepidemiological studies were conducted using different national healthcare databases
OBJECTIVE: Our aim was to investigate the relationship between exposure to antipsychotic drugs and the risk of venous thromboembolism (VTE) in elderly patients. METHODS: A time-matched case-control analysis nested within a cohort of 111,818 patientwith at least 1 antipsychotic drug prescription during 1998 to 2008
AIM: Both tricyclic antidepressants (TCAs) and selective serotonin reuptake inhibitors (SSRIs) have been associated with an increased risk of fractures. The serotonin transporter (5-HTT) has been located in the bone and may play a role in bone physology. We assessed the association between antidepressant drug use, categorized in a therapeutical-based way and on basis of their affinity for the 5-HTT, and the risk of both osteoporotic and non-osteoporotic fractures
CONTEXT: Use of organic nitrates has been associated with increased bone mineral density. Moreover, a large Danish case-control study reported a decreased fracture risk. However, the association with duration of nitrate use, dose frequency, and impct of discontinuation has not been extensively studied
