Abstract
Atherosclerotic cardiovascular disease (ASCVD) represents the major cause of morbidity and mortality worldwide. The onset of the atherosclerosis process occurs during childhood and adolescence, subsequently leading to the onset of cardiovascular disease as young adults. Several cardiovascular risk factors can be identified in children and adolescents; however, hyperlipidemia, in conjunction with the global obesity epidemic, has emerged as the most prevalent, playing a key role in the development of ASCVD. Therefore, screening for hyperlipidemia is strongly recommended to detect high-risk children presenting with these disorders, as these patients deserve more intensive investigation and intervention. Treatment should be initiated as early as possible in order to reduce the risk of future ASCVD. In this review, we will discuss lipid metabolism and hyperlipidemia, focusing on correlations with cardiovascular risk and screening and therapeutic management to reduce or almost completely avoid the development of ASCVD.

Res Social Adm Pharm 2023; 19:547-549. [PMID: 36543634 PMCID: PMC9870927 DOI: 10.1016/j.sapharm.2022.12.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2022] [Revised: 11/14/2022] [Accepted: 12/10/2022] [Indexed: 12/14/2022]
Abstract
INTRODUCTION The efficacy of lipid-lowering therapy in reducing cardiovascular disease in adults is well-established. Unfortunately, it is also well-established that adults have inadequate adherence to lipid-lowering therapy, which is associated with increased costs and mortality. However, the adherence patterns of youth prescribed lipid-lowering therapy is not well-described. METHODS We analyzed data that was prospectively collected from patients <27 years-old who were referred to a large regional preventive cardiology clinic from 2010 to 2017. Adherence to lipid-lowering therapy was self-reported at the patient's most recent clinic visit and categorized as either adequate adherence (≥80%) or inadequate adherence (<80%). We compared adherence rates by demographic factors, class of lipid-lowering therapy, length of time on lipid-lowering therapy, family history, lipid parameters, and laboratory measures of adverse effects. RESULTS In our cohort, we had 318 patients prescribed a lipid-lowering medication over a seven-year period. Of those, 235 (75%) had adequate adherence. Those with adequate adherence had an improved LDL-C (123 mg/dL [standard deviation (SD) 32.3] vs. 167 mg/dL [SD 50.4], p < 0.05), total cholesterol (198 mg/dL [49.5] vs. 239 mg/dL [SD 53.2]), and non-HDL-C (148 mg/dL [SD 38.7] vs. 193 mg/dL [SD 43.9]). In addition, patients with adequate adherence were more likely to reach goal LDL-C of <130 mg/dL than those with inadequate adherence (130 vs. 25, p < 0.01). The relationship between LDL-C and adherence remained statistically significant after controlling for age, gender, and the length of time on therapy (β = -0.66, p < 0.01). Adherence level did not differ by gender, class of lipid-lowering therapy, length of time on lipid-lowering therapy, or presence of a family history of an atherosclerotic event. The findings were similar when we only analyzed those prescribed a statin. CONCLUSIONS Self-reported adherence to lipid-lowering therapy in youth is excellent and was associated with achieving goal LDL-C goals. Obtaining adherence data from patients may help more patients reach LDL-C goals.

Abstract
PURPOSE OF REVIEW Atherosclerosis and associated cardiovascular risk factors originate in childhood; hence, early management of dyslipidaemia is vital. However, hypercholesterolemia remains untreated or undertreated in many youths. We review current therapies, drugs under investigation and consider potential future directions for the management of paediatric dyslipidaemia to highlight the recent evidence and new therapeutic options for future use. RECENT FINDINGS Cardiovascular disease (CVD) risk factors in childhood, including dyslipidaemia, are associated with CVD risk and clinical CVD events in adulthood. Recent data show that initiation of statin therapy in childhood in children with familial hypercholesterolemia reduces the risk of CVD in adulthood. Several well tolerated and efficacious treatment options have become available in recent times for the management of dyslipidaemia in youth. Many new lipid-lowering drugs are under investigation to widen the available choices. Some of these drugs are now available for use in paediatrics, while some remain targets for future use. SUMMARY We review available treatment options for paediatric dyslipidaemia management, discuss potential limitations and propose future directions. We also acknowledge the need for continued research in paediatrics for optimal paediatric dyslipidaemia management.

Abstract
Since lipid abnormalities tend to progress from childhood to adulthood, it is necessary to early identify and treat children and adolescents with dyslipidemia. This is important in order to reduce the cardiovascular risk, delay the development of fatty streaks, slow the progression of atherosclerosis and reverse atherosclerotic plaques. Together with therapeutic lifestyle changes, statins are the most common lipid-lowering drugs. By inhibiting the endogenous cholesterol synthesis in the liver, statins increase the catabolism of LDL-C, reduce VLDL-C, IDL-C and TG and modestly increase HDL-C. Regardless of their lipid-lowering effect, statins have also pleiotropic effects. Statins have increasingly been prescribed in children and adolescents and mounting evidence suggests their beneficial role. As with adults, in children, several studies have demonstrated that statin therapy is efficient at lowering lipid levels and reducing CIMT progression and cumulative estimated atherosclerotic burden in children. Statins are generally very well-tolerated in both adults and children and adverse events are quite uncommon. When evaluating the need and the timing for statin treatment, the presence of several factors (secondary causes, familial history, additional risk factors) should also be considered. Before initiating statins, it is imperative for clinical practitioners to consult patients and families and, as with any new medication therapy, to monitor patients taking statins. Despite being safe and effective, many children with lipid disorders are not on statin therapy and are not receiving the full potential benefit of adequate lipid-lowering therapies. It is therefore important that clinicians become familiar with statins.

Abstract
Zusammenfassung
Hintergrund Kardiovaskuläre Ereignisse sind die wichtigste
Mortalitätsursache in der westlichen Welt. Die familiäre
Hypercholesterinämie (FH) zeichnet sich durch erhöhte
low-density Lipoprotein-Cholesterin- und Gesamtcholesterin-Spiegel im peripheren
Blut aus. Die FH beruht zumeist auf einer genetischen Veränderung im
LDL-Rezeptorgen und gehört zu den häufigsten monogenen
Erkrankungen. Bei der homozygoten Form ist die Mortalität aufgrund
kardiovaskulärer Ereignisse im Kindes- und Jugendalter extrem hoch. Auch
die heterozygote Form der FH führt unbehandelt früh zu
kardiovaskulären Ereignissen und sollte frühzeitig
diagnostiziert und behandelt werden, um eine Atherosklerose zu vermeiden. Die
präventive und sichere Anwendung einer medikamentösen
Lipidsenkung konnte für Kinder gezeigt werden.
Methode Literatursuche in Cochrane library, Medline, NCBI databases.
Ergebnisse Anders als in europäischen Nachbarländern wurde
in Deutschland im Kindesalter kein universelles Screening auf diese
häufige Erkrankung etabliert, obwohl dies in den Leitlinien gefordert
wird. In der vorliegenden Arbeit wird die Literatur untersucht hinsichtlich der
Kausalität der Erkrankung, der Therapie im Kindesalter sowie
hinsichtlich des Zutreffens klassischer und modifizierter Kriterien für
das Durchführen eines vorgeschlagenen universellen FH-Screenings zum 5.
Geburtstag mit anschließendem reversen Kaskadenscreening bei
Verwandten.
Schlussfolgerung Die Autoren plädieren für die
Einführung eines universellen FH-Screenings in Deutschland zur
Vorsorgeuntersuchung U9 mit 5 Jahren. Eine Analyse anhand des Goldstandards
klassischer Kriterien nach Wilson und Jungner sowie anhand im zeitlichen Kontext
angepasster Kriterien zeigt die Vorteile eines universellen
frühkindlichen FH-Screening. Dieses kann präventiv das
kardiovaskuläre Risiko absenken, das Fortschreiten der Atherosklerose
verlangsamen und zu niedrigeren Inzidenzen von Schlaganfall und Herzinfarkt im
Erwachsenenalter beitragen. Neben den diagnostizierten FH-Kindern können
auch deren betroffene Verwandte erkannt werden.

Abstract
INTRODUCTION Statins are lipid-lowering drugs and starting treatment has been associated with DNA methylation changes at genes related to lipid metabolism. However, the longitudinal pattern of how statins affect DNA methylation in relation to lipid levels has not been well investigated. METHODS We conducted an epigenetic association study in a longitudinal Swedish twin sample in previously reported lipid-related CpGs (cg10177197, cg17901584 and cg27243685). First, we applied a mixed-effect model to assess the association between blood lipids (total cholesterol (TC), low-density lipoprotein cholesterol (LDL), high-density lipoprotein cholesterol (HDL), total triglyceride (TG)) and DNA methylation. Then, we performed a piecewise latent linear-linear growth curve model (LGCM) to explore the long-term changing pattern of lipids and methylation in response to statin treatment. Finally, we used a bivariate autoregressive latent trajectory model with structured residuals (ALT-SR) to analyze the cross-lagged effects in different lipid-CpG pairs in statin users and non-users. RESULTS We replicated the associations between TC, LDL, HDL and DNA methylation level in cg17901584 and cg27243685 (P values ranged from 4.70E-12 to 1.84E-04). From the piecewise LGCM, we showed that TC and LDL significantly decreased in statin users before treatment started and then remained stable. For non-statin users, we only found a slightly significant decreasing trend for TC and TG. We observed a similar dynamic pattern for methylation levels at cg27243685 and cg17901584. Before statin initiation, cg27243685 showed a significantly increasing trend and cg17901584 a decreasing trend, but post-treatment, there were no additional changes. From the ALT-SR model, we found TG levels to be significantly associated with the DNA methylation level of cg27243685 at the next measurement in statin users (estimate = 0.383, 95% CI: 0.173, 0.594, P value < 0.001). CONCLUSIONS Longitudinal blood lipid and DNA methylation levels change after statin treatment initiation, where the latter is mostly a response to alterations in lipid levels and not vice versa.

Abstract
ZusammenfassungDie langfristigen kardiovaskulären Folgen des Typ-1-Diabetes determinieren die Lebenserwartung betroffener Kinder und Jugendlicher. Risikofaktoren für deren Entwicklung sind eine längere Diabetesdauer bzw. Diabetesmanifestation im frühen Lebensalter, Hypertonie, Rauchen, hoher BMI sowie Fettstoffwechselstörungen. Das Management der kardiovaskulären Risikofaktoren bei Kindern und Jugendlichen mit Typ-1-Diabetes beinhaltet zum einen Screeningsmaßnahmen zur frühzeitigen Aufdeckung der pathologischen Veränderungen und zum anderen eine Lebensstilanpassung im Sinne einer ausgewogenen, normokalorischen Ernährung, regelmäßiger Bewegung sowie ggf. einer medikamentösen lipid- bzw. blutdrucksenkenden Therapie.Die Leitlinien und Empfehlungen zur standardisierten Erkennung und Behandlung kardiovaskulärer Risikofaktoren bei jungen Menschen mit Typ-1-Diabetes sind bisher uneinheitlich formuliert und werden deshalb nicht immer im klinischen Alltag angewendet bzw. umgesetzt. Dies führt zu einer relevanten Unterversorgung dieser Patientengruppe. Dem gilt es mit mehr Forschungsansätzen und der Entwicklung eines universellen Prozederes zur Diagnostik und Therapie der kardiovaskulären Risikofaktoren entgegenzuwirken.

Abstract
Childhood dyslipidaemia is one of the main traditional cardiovascular risk factors that initiate and exacerbate the atherosclerotic process. Healthcare providers may play a key role in the management of children with lipid abnormalities; however, they have to properly evaluate the normal lipid values and know the available treatment options in children and adolescents. Current guidelines recommend healthy behaviours as the first-line treatment for childhood dyslipidaemia. The therapeutic lifestyle changes should focus on dietary modifications, daily physical activity, reduction in body weight and tobacco smoking cessation. Parents play a key role in promoting their children's healthy habits. In children with more severe forms of lipid abnormalities and in those who do not benefit from healthy behaviours, pharmacological therapy should be considered. Safe and effective medications are already available for children and adolescents. Statins represent the first-line pharmacological option, while ezetimibe and bile acid sequestrants are usually used as second-line drugs. Despite their limited use in children, other lipid-lowering agents (already approved for adults) are currently available or under study for certain categories of paediatric patients (e.g., familial hypercholesterolemia). Further studies are needed to evaluate the long-term efficacy, safety and tolerability of novel lipid-lowering drugs, especially in children.

Abstract
Purpose of Review To elucidate the current approach of care in pediatric patients with familial hypercholesterolemia (FH). We sought an answer to the question whether the advances and major changes in lipid management are relevant and apply to children and adolescents. Recent Findings Latest research findings clearly demonstrate that lowering cholesterol levels at a young age prevents vascular atherosclerotic changes and decreases cardiovascular events in adulthood and emphasizes the importance of early detection and intervention in the pediatric FH patients group. Summary FH is a common genetic disease caused by mutations in genes associated with the metabolism of low-density lipoproteins (LDL). The hallmark of FH is elevated LDL cholesterol (LDL-C) levels from birth and premature atherosclerotic cardiovascular disease (ASCVD). Often FH is either undiagnosed or diagnosed with a considerable delay, leading to vascular atherosclerotic changes and cardiovascular disease. Prompt identification of FH subjects is essential, to initiate early preventive measures. Safe and efficient pharmacological agents are approved for use in children and adolescents. Statins are the first line of therapy, in combination of ezetimibe. Unfortunately, these drugs do not warrant the achievement of therapeutic target, especially in HoFH patient. In the latter, lipoprotein apheresis (LA), which has been shown to be safe and effective, is strongly recommended. Finally, the new drugs still under study will allow a multimodal customized treatment. Lowering cholesterol levels at a young age hinders vascular atherosclerotic changes decreasing cardiovascular events in adulthood. Therefore, early detection, diagnosis, and intervention in FH patients are priority objectives.

Abstract
Current scientific evidence has proven that atherosclerosis is a process that begins in childhood and tracks into adulthood, likely culminating in adverse cardiovascular events such as coronary artery disease, peripheral artery disease, and stroke. In addition, the obesity epidemic and increasing awareness of genetic lipid disorders has made the understanding and management of lipid disorders necessary for pediatricians. Childhood offers a unique opportunity for preventing, modifying, or eliminating risk factors and, in doing so, reversing or slowing the process of atherosclerosis. In general, management involves targeted lifestyle interventions such as strict dietary changes and increases in physical activity. In some circumstances, pharmacotherapy, even in childhood, is warranted. [Pediatr Ann. 2021;50(3):e105-e112.].

Abstract
Carotid intima-media thickness (cIMT) has been proposed as an early marker of subclinical atherosclerosis in high risk children. Children with heterozygous familial hypercholesterolemia have greater cIMT than matched healthy controls or their unaffected siblings. Statin therapy may delay the progression of cIMT, although long-term studies in children are scarce. We evaluated the effect of atorvastatin treatment on cIMT in children with dyslipidemia. We studied 81 children/adolescents, 27 with severe dyslipidemia (low-density lipoprotein cholesterol [LDL-C] ≥190 mg/dL) and 54 sex- and age-matched healthy controls; LDL-C ≤ 130 mg/dL and lipoprotein (a), Lp(a), ≤30 mg/dL. In the children with dyslipidemia, cIMT was measured twice, before and on treatment (18.2 ± 7.7 months). Anthropometric data, a full lipid profile, liver, kidney, and thyroid function were evaluated. Males with dyslipidemia had a greater cIMT than male controls after adjustment for other factors (P = .049). In addition, a nonstatistically significant decrease in cIMT was observed after treatment (P = .261). Treatment with atorvastatin resulted in a significantly improved lipid profile. Females with dyslipidemia had a significantly thinner cIMT than males. Children with normal and high Lp(a) levels had similar cIMT values. In conclusion, treatment with atorvastatin had a beneficial effect on the lipid profile and cIMT progression in children with severe dyslipidemia.

Abstract
BACKGROUND Statin use for hypercholesterolemia in children is predominantly reported from short-term clinical trials. In this study, we assess the efficacy and safety of statin treatment in clinical pediatric practice. METHODS Records of all patients who began statin treatment at age <18 years and remained on statins for >6 months from 5 pediatric lipid clinics were reviewed. Information at baseline and from all clinic evaluations after statin initiation was recorded, including lipid measurements, statin drug/dose, safety measures (anthropometry, hepatic enzymes, creatine kinase levels), and symptoms. Lipid changes on statin therapy were assessed from baseline to 6 ± 3 months and from 6 ± 3 months to last follow-up with a mixed-effects model, using piecewise linear splines to describe temporal changes, controlling for repeated measures, sex, and age. RESULTS There were 289 patients with median low-density lipoprotein cholesterol (LDL-C) of 5.3 mmol/L (interquartile range [IQR]:4.5-6.5) and mean age of 12.4 ± 2.9 years at statin initiation. Median duration of therapy was 2.7 years (IQR: 1.6-4.5) with 95% on statins at last evaluation. There were significant decreases in total cholesterol, LDL-C, and non-high-density lipoprotein cholesterol (non-HDL-C) from baseline to 6 ± 3 months (P < 0.001) and from 6 ±3 months to last follow-up (P < 0.001). Triglycerides and HDL-C were unchanged but the triglyceride to HDL-C ratio decreased significantly by late follow-up. At final evaluation, median LDL-C had decreased to 3.4 mmol/L (IQR:2.8-4.2). No patient had statins discontinued for safety measures or symptoms. CONCLUSIONS In real-world clinical practice, intermediate-term statin treatment is effective and safe in children and adolescents with severe LDL-C elevation.

Abstract
BACKGROUND The use of statins in children, although not frequent, is recommended in specific clinical contexts, namely, familial hypercholesterolaemia, conditions carrying a moderate-high cardiovascular risk and sub-optimal cholesterol levels after implementation of lifestyle modifications. The aim of this study is to characterise children with dyslipidaemia managed with statins, followed at a tertiary referral centre in central Portugal. METHODS AND RESULTS The authors carried out a retrospective and descriptive study made up of 66 patients (50% males, mean age of therapy onset 11.9 years) followed up at the Cardiovascular Clinic of a tertiary referral centre between January, 2012, and May, 2018. Clinical, analytical, and echocardiographic parameters were analysed. About 60.6% had clinical and/or molecular diagnosis of familial hypercholesterolaemia. On average, each patient had three cardiovascular risk factors, obesity (31%) being most prevalent, followed by arterial hypertension (14%). Statin therapy showed a statistically significant reduction in the lipid profile, particularly in the total cholesterol (23%) and low-density lipoprotein cholesterol (30%) levels, as well as in the carotid intima-media thickness (p = 0.015). Hepatic and muscle integrity markers were within normal range. CONCLUSIONS Statins are safe and efficient in the management of children with hypercholesterolaemia. Our study showed that apart from its lipid-lowering properties, it also reduced significantly the carotid intima-media thickness and, implicitly, the cardiovascular risk of these patients.

Nine-year overview of dyslipidemia management in children with heterozygous familial hypercholesterolemia: a university hospital outpatient lipid clinic project in Northwestern Greece. J Pediatr Endocrinol Metab 2020; 33:533-538. [PMID: 32084003 DOI: 10.1515/jpem-2019-0250] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/04/2019] [Accepted: 01/15/2020] [Indexed: 02/03/2023]
Abstract
Background To assess the efficacy and safety of lipid-lowering treatment in children with heterozygous familial hypercholesterolemia (HeFH) aged ≤12 years attending a tertiary hospital-based outpatient lipid clinic. Methods Data in 318 children from the University Hospital of Ioannina (Northwestern Greece) Outpatient Lipid Clinic Project for Children and Adolescents with Dyslipidemia from March 2009 to December 2018 were analyzed. We assessed the efficacy and safety treatment alongside any possible predictors of the achievement of the treatment target. Results Of 318 children with hyperlipidemia, 72 were diagnosed having HeFH based on clinical criteria and genetic confirmation. Compared with non-familial hypercholesterolemia (non-FH) children, those with FH had a higher occurrence of positive family history of premature cardiovascular disease, and higher levels of total, low-density lipoprotein-cholesterol (LDL-C), apolipoprotein B (apoB) and lipoprotein (a) (Lp(a)). Treatment regimens included either atorvastatin 10-20 mg/day, rosuvastatin 5-10 mg/day, pitavastatin 2-4 mg/day monotherapy or in combination with ezetimibe. The treatment goal of LDL-C (<135 mg/dL, 3.5 mmol/L) was achieved in 69% of children treated. The achievement of the treatment targets correlated positively with male sex and inversely with the Dutch Lipid Clinic Network Score, baseline total, LDL-C and apoB levels. No clinically significant changes in liver or muscle-related laboratory tests were reported; no effect on growth or sexual maturation was noted. Conclusions This study confirms that lipid-lowering treatment in HeFH children initiated in the setting of a specialized tertiary hospital-based outpatient lipid clinic is efficacious and safe. Children of male sex and low baseline lipid values had a better achievement of treatment target.

Abstract
OBJECTIVES To describe muscle-related statin adverse effects in real-world pediatric practice. STUDY DESIGN Using prospectively collected quality improvement data from a pediatric preventive cardiology practice, we compared serum creatine kinase (CK) levels among patients prescribed and not prescribed statins, and pre-/poststatin initiation. Multivariable mixed-effect models were constructed accounting for repeated measures, examining the effect of statins on log-transformed CK (lnCK) levels adjusted for age, sex, weight, season, insurance type, and race/ethnicity. RESULTS Among 1501 patients seen over 3.5 years, 474 patients (14?±?4 years, 47% female) had at least 1 serum CK measured. Median (IQR) CK levels of patients prescribed (n?=?188 patients, 768 CK measurements) and not prescribed statins (n?=?351 patients, 682 CK measurements) were 107 (83) IU/L and 113 (81) IU/L, respectively. In multivariable-adjusted models, lnCK levels did not differ based on statin use (??=?0.02 [SE 0.05], P?=?.7). Among patients started on statins (n?=?86, 130 prestatin and 292 poststatin CK measurements), median CK levels did not differ in adjusted models (? for statin use on lnCK?=?.08 [SE .07], P?=?.2). There was a clinically insignificant increase in CK over time (??=?.08 [SE .04], P?=?.04 per year). No muscle symptoms or rhabdomyolysis were reported among patients with high CK levels. CONCLUSIONS In a real-world practice, pediatric patients using statins did not experience higher CK levels, nor was there a meaningful CK increase with statin initiation. These data suggest the limited utility to checking CK in the absence of symptoms, supporting current guidelines.
