RESUMO
BACKGROUND: Cardiovascular disease (CVD) is one of the leading causes of death in Belgium. Current strategies for the prevention and management of CVD focus on reducing low-density lipoprotein cholesterol (LDL-C) levels. This analysis assessed whether LDL-C goals, recommended by the European Society of Cardiology (ESC)/European Atherosclerosis Society (EAS) guidelines, were being achieved in a Belgian study population. METHODS: The cross-sectional, observational, DA VINCI study enrolled patients prescribed lipid-lowering therapy (LLT) between 21 June 2017 and 20 November 2018. Data for patients from Belgium were extracted for this country-specific analysis. Primary endpoint was the proportion of patients who achieved 2016 ESC/EAS risk-based LDL-C goals; attainment of 2019 risk-based LDL-C goals was evaluated post hoc. RESULTS: Of 497 enrolled patients, 41% were female and mean age was 68 years. Among subjects with an LDL-C measurement on stabilised LLT, moderate-intensity statin monotherapy was the most prescribed LLT regimen (59%). Overall, 63% of patients achieved their risk-based LDL-C goals according to the 2016 ESC/EAS guidelines. Among patients with established ASCVD, risk-based LDL-C goal attainment was higher in patients with peripheral arterial disease (53%) than patients with coronary (37%) and cerebrovascular disease (42%). According to the updated 2019 ESC/EAS guidelines, less than half (41%) of patients achieved their risk-based LDL-C goal. The proportion of primary and secondary prevention patients who achieved 2019 risk-based LDL-C goals was 59% and 18%, respectively. CONCLUSION: These findings reveal a large gap between the LDL-C goals advocated by the ESC/EAS and the levels achieved in routine clinical practice in Belgium.
RESUMO
Seasonal influenza vaccine formulations must be updated annually to correspond to the influenza viruses in circulation. This was an uncontrolled, open-label, multi-center phase IV study conducted in Belgium to comply with interim European Medicines Agency (EMA) guidelines for rapidly evaluating the safety of newly formulated seasonal influenza vaccines. Adult volunteers received one dose of the 2014-2015 Northern Hemisphere formulation of licensed intradermal trivalent influenza vaccine at either the standard dose (9µg hemagglutinin/strain for 18-59 year-olds) or the high dose (15µg hemagglutinin/strain for ≥ 60 year-olds). Vaccinees recorded their solicited reactions and unsolicited adverse events for 7 d after vaccination. Solicited reaction frequencies were compared to historical reference values obtained from previous clinical trials to determine if the new formulations were excessively reactogenic or allergenic. A total of 210 participants (105 per age group) were included and vaccinated in October 2014. In both groups, pain, erythema, and pruritus were the most common solicited injection site reactions, and headache and myalgia were the most common solicited systemic reactions. Although the frequencies of shivering in 18-59 year-olds and malaise in ≥ 60 year-olds were higher than historical reference values, they were not considered indicative of excessive reactogenicity because almost all of these reactions were mild. The study design was endorsed by the EMA and permitted the reactogenicity of both vaccine formulations to be assessed within one month by collecting adverse events for 7 d. Both formulations exhibited acceptable safety profiles although this should be confirmed through forthcoming enhanced post-marketing safety surveillance systems.
