Abstract
A One Health lens is increasingly significant to address the intertwined challenges in planetary health concerned with the health of humans, nonhuman animals, plants, and ecosystems. A One Health approach can benefit the public health systems in Africa that are overburdened by noncommunicable, infectious, and environmental diseases. Notably, the COVID-19 pandemic revealed the previously overlooked two-fold importance of pharmacogenetics (PGx), for individually tailored treatment of noncommunicable diseases and environmental pathogens. For example, dyslipidemia, a common cardiometabolic risk factor, has been identified as an independent COVID-19 severity risk factor. Observational data suggest that patients with COVID-19 infection receiving lipid-lowering therapy may have better outcomes. However, among African patients, the response to these drugs varies from patient to patient, pointing to the possible contribution of genetic variation in important pharmacogenes. The PGx of lipid-lowering therapies may underlie differences in treatment responses observed among dyslipidemia patients as well as patients comorbid with COVID-19 and dyslipidemia. Genetic variations in APOE, ABCB1, CETP, CYP2C9, CYP3A4, CYP3A5, HMGCR, LDLR, NPC1L1, and SLCO1B1 genes affect the pharmacogenomics of statins, and they have individually been linked to differential responses to dyslipidemia and COVID-19 treatment. African populations are underrepresented in PGx research. This leads to poor accounting of additional diverse genetic variants that could be important in understanding interindividual and between-population variations in therapeutic responses to dyslipidemia and COVID-19. This expert review examines and synthesizes the salient and priority PGx variations, as seen through a One Health lens in Africa, to improve and inform personalized medicine in both dyslipidemia and COVID-19.

Reda A, Ragy H, Saeed K, Alhussaini MA. A semi-systematic review on hypertension and dyslipidemia care in Egypt-highlighting evidence gaps and recommendations for better patient outcomes. JOURNAL OF THE EGYPTIAN PUBLIC HEALTH ASSOCIATION 2021; 96:32. [PMID: 34851468 PMCID: PMC8634749 DOI: 10.1186/s42506-021-00096-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/05/2021] [Accepted: 11/16/2021] [Indexed: 12/25/2022]
Abstract
Background Both hypertension and dyslipidemia are considered as major modifiable risk factors of cardiovascular diseases (CVDs), and their prevalence in Egypt has increased in recent years. Evidence-based systematic evaluation of data on hypertension and dyslipidemia is critical for effective patient-centric management to reduce the overall risk of CVDs in Egypt. This semi-systematic review aimed to quantify and identify data gaps in the prevalence and distribution of patient journey touchpoints including awareness, screening, diagnosis, treatment, adherence, and control of hypertension and dyslipidemia to provide the basis for research prioritization, practice guidance, and health care reforms in Egypt. Main body Structured search was conducted on MEDLINE and Embase to identify articles published in English between January 2010 and December 2019 that reported key patient journey touchpoints in hypertension and dyslipidemia management. Unstructured search was conducted on public or government websites with no date restriction. Data from all sources were extracted and presented descriptively. In total, 22 studies published between 1995 and 2020 on hypertension and dyslipidemia were included in the final analyses. The prevalence of hypertension in Egypt ranged from 12.1 to 59%. Studies reported awareness (37.5% and 43.9%), diagnosis (42% and 64.7%), treatment (24% and 54.1%), and adherence to antihypertensive medication (51.9%) to be low. Furthermore, the percentage of patients who had their blood pressure controlled ranged from 8 to 53.2%. The prevalence of dyslipidemia varied in the general population (range 19.2–36.8%) but was higher in patients with acute coronary syndrome (ACS) (50.9% and 52.5%) and coronary artery disease (58.7%). A national report indicated that 8.6% of the general population was screened for dyslipidemia; however, no data was available on the diagnosis and treatment rates. Among ACS patients, 73.9% were treated for dyslipidemia. Data indicated low levels of medication adherence (59%) among dyslipidemia patients, with overall low control rates ranging from 5.1 to 34.4% depending on CVD risk in populations including ACS patients. Conclusion Data on patient journey touchpoints of hypertension and dyslipidemia are limited in Egypt, indicating the need for more systematic and high-quality evidence-based studies covering different aspects of patient-centric management for better management of CVD and its risk factors.

Abstract
Background Numerous epidemiological investigations and randomized clinical studies have determined that dyslipidemia is a major contributor to atherosclerotic cardiovascular disease (ASCVD). Consequently, the management of serum cholesterol and low-density lipoprotein levels has become a central objective in the effort to prevent cardiovascular events. Main body Many guidelines were issued by different organizations and societies to define patient risk and establish important recommendations for management strategies. Newer cholesterol-lowering agents (non-statin drugs) are described, and their use is directed primarily to secondary prevention in patients at very high risk of new ASCVD. Conclusion The present guidance summarizes the current methods for risk estimation and outlines the most recent data on lipid management in a simple user-friendly format, to improve physician awareness and help implement guidelines in the daily practice.
