Barriers to Early Diagnosis and Treatment of Familial Hypercholesterolemia: Current Perspectives on Improving Patient Care.

Familial hypercholesterolemia (FH) is a frequent disorder associated with premature atherosclerotic cardiovascular disease. Different clinical diagnosis criteria are available, and cost of genetic testing has been reduced in the last years; however, most cases are not diagnosed worldwide. Patients with FH are at high cardiovascular risk and the risk can be reduced with lifelong lifestyle and pharmacological treatment. Statins and ezetimibe are available as generic drugs in most countries reducing the cost of treatment. However, the use of high-intensity statins combined with ezetimibe and PCSK9 inhibitors, if necessary, is low for different reasons that contribute to a high number of patients not reaching LDL-C targets according to guidelines. On the other hand, cardiovascular risk varies greatly in families with FH; therefore, risk stratification strategies including cardiovascular imaging is another element to consider for improving care and management of FH. There are numerous barriers depending on the awareness, knowledge, perception of risk, management and care of patients living with FH that impact in the diagnosis and treatment of the disorder. In this contemporary review, we analyze different barriers in the diagnosis and care of patients to improve patients' care and prevention of atherosclerotic cardiovascular disease and describe recent advances and strategies to improve the gaps in the care of FH, including global collaboration and advocacy.

Dislipidemia aterogénica en latino américa: prevalencia, causas y tratamiento / Atherogenic dyslipidemia in Latin America: prevalence, causes and treatment

En las guías clínicas actuales, la dislipidemia aterogénica (DA) es una entidad no muy atendida. Debido a las frecuentes alteraciones en los lípidos asociados a la DA en Latino América (LA). Métodos: organizamos un grupo de expertos denominado Academia Latino Americana para el estudio de los Lípidos (ALALIP) para así generar un documento con análisis de su prevalencia y recomendaciones terapéuticas prácticas. Se utilizó la metodología Delphi modificada, con una revisión integral de la literatura y énfasis en las publicaciones con implicaciones para LA. Subsecuentemente, desarrollamos preguntas claves para ser discutidas. Resultados: En Latinoamérica (LA) no existe un estudio global sobre los factores de riesgo que representan a la totalidad de la población. El análisis sistemático de las encuestas nacionales de salud y de los estudios sistemáticos de cohorte muestran consistentemente una alta prevalencia de las anormalidades lipídicas que definen la DA. La concentración baja del colesterol unido a las lipoproteínas de alta densidad (C-HDL) varía entre 34,1% a 53,3% y la de triglicéridos (TG) elevados del 25,5% al 31,2%, con mayor prevalencia entre los hombres. La DA bien puede ser tratada con los cambios del estilo de vida (CTEV) como ncremento en laactividad física, dieta baja en carbohidratos y alta en ácidos grasos poliinsaturados, tales como los ácidos grasos omega-3 como intervención primaria. De ser necesario, esta estrategia sera suplementada con terapia farmacológica como la monoterapia con estatinas o la combinación de fibratos/ácidos grasos omega-3. Conclusiones: Las anormalidades lipídicas que definen la DA tienen una elevada prevalencia en LA; su interacción con un estilo de vida no saludable, herencia y cambios epigenéticos están ligados a sus posibles causas. La DA es una causa importante de riesgo cardiovascular residual (RCVR) que debe ser diagnosticada y tratada. Es importante y necesario diseñar un estudio global de factores de riesgo en LA para conocer la real prevalencia de la DA(AU)

Due to the frequent lipid alterations associated with AD in Latin America (LA), we organized a group of experts named Latin American Academy for the study of Lipids (ALALIP), to generate a document to analize it´s prevalence and to offer practical recommendations. Methodology: Using the Delphi methodology, we conducted a comprehensive literature review, with emphasis on those publications with implications for LA. Subsequently we developed key questions to be discussed. Results: In LA There is no a global study on risk factors that represent the entire population. The systematic analysis of national health surveys and regional cohort studies showed a consistent high prevalence of the lipid abnormalities that define AD. Low high density lipoprotein cholesterol (HDL-C) ranges from 34.1% to 53.3% and elevated triglycerides (TG) from 25.5% to 31.2% more prevalent in men. There are multiple causes: high consumption of foods with a high caloric density, cholesterol and trans fats, sedentary lifestyle and epigenetic changes. AD must be well treated with therapeutic changes in lifestyle with increase in physical activities, regular exercise and a diet with a low proportion of carbohydrates and rich in poliunsatured fatty acid, such as omega-3 fatty acids as primary intervention. If needed, this strategy must be supplemented with pharmacological therapies such as monotherapy with statins or a combination of fibrates plus omega-3. fatty acid. conclusions: Lipid abnormalities that define AD have a high prevalence in LA; the interaction between non-healthy lifestyle, inheritance and epigenetic changes, possibly are the cause. AD is an important cause of cardiovascular residual risk (CVRR), that must be diagnosed and treated It is important and necesary to design a global study of risk factors in LA to know the true prevalence of AD(AU)

Pooling and expanding registries of familial hypercholesterolaemia to assess gaps in care and improve disease management and outcomes: Rationale and design of the global EAS Familial Hypercholesterolaemia Studies Collaboration.

BACKGROUND: The potential for global collaborations to better inform public health policy regarding major non-communicable diseases has been successfully demonstrated by several large-scale international consortia. However, the true public health impact of familial hypercholesterolaemia (FH), a common genetic disorder associated with premature cardiovascular disease, is yet to be reliably ascertained using similar approaches. The European Atherosclerosis Society FH Studies Collaboration (EAS FHSC) is a new initiative of international stakeholders which will help establish a global FH registry to generate large-scale, robust data on the burden of FH worldwide. METHODS: The EAS FHSC will maximise the potential exploitation of currently available and future FH data (retrospective and prospective) by bringing together regional/national/international data sources with access to individuals with a clinical and/or genetic diagnosis of heterozygous or homozygous FH. A novel bespoke electronic platform and FH Data Warehouse will be developed to allow secure data sharing, validation, cleaning, pooling, harmonisation and analysis irrespective of the source or format. Standard statistical procedures will allow us to investigate cross-sectional associations, patterns of real-world practice, trends over time, and analyse risk and outcomes (e.g. cardiovascular outcomes, all-cause death), accounting for potential confounders and subgroup effects. CONCLUSIONS: The EAS FHSC represents an excellent opportunity to integrate individual efforts across the world to tackle the global burden of FH. The information garnered from the registry will help reduce gaps in knowledge, inform best practices, assist in clinical trials design, support clinical guidelines and policies development, and ultimately improve the care of FH patients.

LL37 loaded nanostructured lipid carriers (NLC): A new strategy for the topical treatment of chronic wounds.

The LL37 is a human antimicrobial peptide which not only has a broad spectrum of antimicrobial activity, but it has also been proved to modulate wound healing by participating in angiogenesis, epithelial cell migration and proliferation, and immune response. In this work, LL37 has been encapsulated in nanostructured lipid carriers (NLCs), produced by the melt-emulsification method, in order to improve its effectiveness. The characterisation of the NLC-LL37 showed a mean size of 270nm, a zeta potential of -26mV and an encapsulation efficiency of 96.4%. The cytotoxicity assay performed in Human Foreskin Fibroblasts demonstrated that the NLC-LL37 did not affect cell viability. Moreover, the in vitro bioactivityassay evidenced that the peptide remained active after the encapsulation, since the NLC-LL37 reversed the activation of the macrophages induced by LPS in the same way as the LL37 in solution. In addition, the in vitro antimicrobial assay revealed the NLC-LL37 activity against Escherichia coli. The effectiveness of the nanoparticles was assessed in a full thickness wound model indb/dbmice. The data demonstrated that NLC-LL37 significantly improved healing compared to the same concentration of the LL37 solution in terms of wound closure, reepithelisation grade and restoration of the inflammatory process. Overall, these findings suggest a promising potential of the NLC-LL37 formulation for chronic wound healing.

Treating homozygous familial hypercholesterolemia in a real-world setting: Experiences with lomitapide.

Homozygous familial hypercholesterolaemia (HoFH) is a rare genetic disease characterised by markedly elevated plasma levels of low-density lipoprotein-cholesterol (LDL-C). Lomitapide is a microsomal triglyceride transfer protein (MTP) inhibitor approved as an adjunct to other lipid-lowering therapies (LLTs), with or without lipoprotein apheresis (LA), for the treatment of adult HoFH. Diet with <20% calories from fat is required. Due to a varying genetic and phenotypic profile of patients with HoFH, individual patients may respond to therapy differently; therefore examining individual cases in a 'real-world' setting provides valuable information on the effective day-to-day management of HoFH cases. Four HoFH cases were selected for analysis and discussion: a 20-year-old female compound heterozygote; a 62-year old female homozygote; a 42-year-old female compound heterozygote; and a 36-year-old male homozygote. Each patient was commenced on lomitapide according to the prescribed protocol and subjected to routine follow-up. All four patients experienced clinically meaningful reductions in LDL-C levels of 35-73%. Three of the patients had evidence of steatosis or mildly elevated liver function tests) before lomitapide was started, but effects of lomitapide on hepatic function were not universal. Three of the patients experienced gastrointestinal adverse events, but were managed with appropriate dietary control. Lomitapide is an effective adjunct LLT in the management of patients with HoFH, with or without LA. Real-world use of lomitapide has a side-effect profile consistent with clinical trials and one that can be managed by adherence to recommendations on dose escalation, dietary modification and dietary supplements.

Omega-3 fatty acids and blood pressure.

Epidemiological and clinical studies suggest that consumption of omega (ω-3) polyunsaturated fatty acids (PUFA) contributes to the reduction of cardiovascular mortality through different mechanisms including modulation of cellular metabolic functions, gene expression and beneficial effects on lipid profile or blood pressure. The aim of the study is to review the effects of ω-3 PUFA supplemented as fish oil or blue fish in blood pressure. The analysis of different studies suggests that high doses ω-3 PUFA ( ≥ 3 g/day) produces a small but significant decrease in blood pressure, especially systolic blood pressure, in older and hypertensive subjects; however, the evidence is not consistent among different studies. ω-3 polyunsaturated fatty acids consumption might have a place in the control of patients with mild hypertension before starting drug treatment and of those who prefer changes of lifestyles like diet.
