- BACKGROUND AND AIMS: The aims of this study were to investigate (1) if P2Y(12) polymorphisms defining the P2Y(12) H2 allele are associated with any other SNPs that may explain the previously reported association with increased ADP induced platelet activation and association with peripheral arterial disease and coronary artery disease and (2) if such variants are associated with acute myocardial infarction (AMI) or classical risk factors for AMI. METHODS AND RESULTS: The P2Y(13) Met-158-Thr polymorphism was found to be in linkage disequilibrium (LD) with the P2Y(12) H2 haplotype (all examined SNPs: D' = 1.0, r(2) = 0.936-1.0), defining a novel P2Y(12) H2/P2Y(13) Thr-158 haplotype. Genotyping of an AMI case control population (n = 1244 cases, 2488 controls) revealed no association of the P2Y(13) Thr-158 allele with AMI (OR = 0.96, 95% C.I. 0.82-1.12, P = 0.63). Also, no differences between the genotype frequencies of P2Y(13) Met-158-Met and Met-158-Thr/Thr-158-Thr were seen in AMI case-control subpopulations (early onset AMI OR = 1.06, 95% C.I. 0.85-1.31, P = 0.62); family history of AMI (OR = 0.98, 95% C.I. 0.78-1.22, P = 0.83) nor in early onset AMIs with family history of AMI (OR = 1.0, 95% C.I. 0.74-1.36, P = 1.0). Genotyping of the P2Y(13) Met-158-Thr polymorphism in a population based sample (n = 6055) revealed no association with cardiovascular risk factors. In addition, the P2Y(13) Met-158-Thr polymorphism was genotyped in a diabetes case-control population, and associations were found neither with DM nor with any examined DM risk factors. CONCLUSION GENOTYPING: The P2Y(13) Met-158-Thr polymorphism is in tight LD with the P2Y(12) locus but is not associated with AMI or classical cardiovascular risk factors.

- Background: Repeat prescribing used in long-term pharmacotherapy is often associated with inadequate patient medication, including non-adherence. In this paper we explore patients' drug refill adherence with repeat prescriptions and relate refill data to patient age and gender, type of prescriber, type of prescribed drug, and reimbursement level. Methods: During one week of 2002, copies of 3636 repeat prescriptions filled at 16 large Swedish pharmacies were collected. Satisfactory refill adherence was defined as dispensed refills covering 80-120% of the prescribed treatment time. Under- and oversupplying were defined as < 80% and > 120% coverage, respectively. Result: The average level of refill adherence was 57%, and the level of under- and oversupplying 21% and 22%, respectively. There was no gender difference. Patients who were exempt from payment had higher oversupplies than others (33% versus 19%), and patients of general practitioners had higher refill adherence than patients of hospital physicians. The highest refill adherence was observed for contraceptives (81%) and the lowest for anti-asthmatics, proton pump inhibitors and non-steroidal anti-inflammatory drugs (30-40%). Conclusions: Refill non-adherence includes both under- and oversupplying and may vary due to different attitudes between prescribers and between patients. Different therapeutic indications and reimbursement systems are other apparent causes. These observations should be considered in programs aiming to assist patients in following medication prescriptions.
