RESUMO

Background: Statins are a highly effective lipid-lowering therapy associated with significant reductions in atherosclerotic cardiovascular disease (ASCVD) events and death. Despite these benefits, statins are underutilized. Pharmacist-led interventions to increase statin prescribing are effective. To our knowledge, no prior studies implemented a comprehensive cardiovascular risk assessment utilizing point-of-care (POC) testing in community pharmacies. Objectives: The primary objective was to determine if community pharmacists can be utilized to identify gaps in care regarding appropriate use of statin therapy for prevention of ASCVD events in HPSAs. Secondary objectives were to assess public interest in ASCVD risk assessment and statin prescribing by the pharmacist, and to identify factors associated with statin gaps in care. Methods: A cross-sectional study was conducted at three independent community pharmacies. Participants were identified based on age and medication history and were scheduled at their pharmacy to receive a comprehensive ASCVD risk screening consisting of POC measurement of a complete lipid panel, blood glucose or A1C, and blood pressure. Participants were informed of their statin candidacy at the screening. Participants completed a survey regarding perceptions of the services provided and opinions of statin prescribing by pharmacists. Results: Of the 57 participants, 43 (75.4%) were possible statin candidates. Most indicated trusting their pharmacist to prescribe a cholesterol-lowering medication and felt insurance should pay for these screenings. Conclusion: ASCVD risk assessment conducted within the community pharmacy setting can be utilized to identify treatment gaps in statin use. Participants indicated trusting pharmacists to provide this service and found the service valuable.

RESUMO

BACKGROUND: MNS blood group system genes GYPA and GYPB share a high degree of sequence homology and gene structure. Homologous exchanges between GYPA and GYPB form hybrid genes encoding hybrid glycophorins GP(A-B-A) and GP(B-A-B). Over 20 hybrid glycophorins have been characterised. Each has a distinct phenotype defined by the profile of antigens expressed including Mia. Seven hybrid glycophorins carry Mia and have been reported in Caucasian and Asian population groups. In Australia, the population is diverse; however, the prevalence of hybrid glycophorins in the population has never been determined. The aims of this study were to determine the frequency of Mia and to classify Mia-positive hybrid glycophorins in an Australian blood donor population. METHOD: Blood samples from 5,098 Australian blood donors were randomly selected and screened for Mia using anti-Mia monoclonal antibody (CBC-172) by standard haemagglutination technique. Mia-positive red blood cells (RBCs) were further characterised using a panel of phenotyping reagents. Genotyping by high-resolution melting analysis and DNA sequencing were used to confirm serology. RESULT: RBCs from 11/5,098 samples were Mia-positive, representing a frequency of 0.22%. Serological and molecular typing identified four types of Mia-positive hybrid glycophorins: GP.Hut (n = 2), GP.Vw (n = 3), GP.Mur (n = 5), and 1 GP.Bun (n = 1). GP.Mur was the most common. CONCLUSION: This is the first comprehensive study on the frequency of Mia and types of hybrid glycophorins present in an Australian blood donor population. The demographics of Australia are diverse and ever-changing. Knowing the blood group profile in a population is essential to manage transfusion needs.

RESUMO

BACKGROUND: The RhD blood group antigen is extremely polymorphic and the DEL phenotype represents one such class of polymorphisms. The DEL phenotype prevalent in East Asian populations arises from a synonymous substitution defined as RHD*1227A. However, initially, based on genomic and cDNA studies, the genetic basis for a DEL phenotype in Taiwan was attributed to a deletion of RHD Exon 9 that was never verified at the genomic level by any other independent group. Here we investigate the genetic basis for a Caucasian donor with a DEL partial D phenotype and compare the genomic findings to those initial molecular studies. STUDY DESIGN AND METHODS: The 3'-region of the RHD gene was amplified by long-range polymerase chain reaction (PCR) for massively parallel sequencing. Primers were designed to encompass a deletion, flanking Exon 9, by standard PCR for Sanger sequencing. Targeted sequencing of exons and flanking introns was also performed. RESULTS: Genomic DNA exhibited a 1012-bp deletion spanning from Intron 8, across Exon 9 into Intron 9. The deletion breakpoints occurred between two 25-bp repeat motifs flanking Exon 9 such that one repeat sequence remained. CONCLUSION: Deletion mutations bordered by repeat sequences are a hallmark of slipped-strand mispairing (SSM) event. We propose this genetic mechanism generated the germline deletion in the Caucasian donor. Extensive studies show that the RHD*1227A is the most prevalent DEL allele in East Asian populations and may have confounded the initial molecular studies. Review of the literature revealed that the SSM model explains some of the extreme polymorphisms observed in the clinically significant RhD blood group antigen.
