Aims Lipoprotein(a) [Lp(a)] is a causal and independent risk factor for cardiovascular disease (CVD). People with elevated Lp(a) are often prescribed statins as they also often show elevated low-density lipoprotein cholesterol (LDL-C) levels. While statins are well-established in lowering LDL-C, their effect on Lp(a) remains unclear. We evaluated the effect of statins compared to placebo on Lp(a) and the effects of different types and intensities of statin therapy on Lp(a). Methods and results We conducted a systematic review and meta-analysis of randomized trials with a statin and placebo arm. Medline and EMBASE were searched until August 2019. Quality assessment of studies was done using Cochrane risk-of-bias tool (RoB 2). Mean difference of absolute and percentage changes of Lp(a) in the statin vs. the placebo arms were pooled using a random-effects meta-analysis. We compared effects of different types and intensities of statin therapy using subgroup- and network meta-analyses. Certainty of the evidence was determined using GRADE (Grading of Recommendations, Assessment, Development, and Evaluation). Overall, 39 studies (24 448 participants) were included. Mean differences (95% confidence interval) of absolute and percentage changes in the statin vs. the placebo arms were 1.1 mg/dL (0.5–1.6, P Conclusion Statin therapy does not lead to clinically important differences in Lp(a) compared to placebo in patients at risk for CVD. Our findings suggest that in these patients, statin therapy will not change Lp(a)-associated CVD risk.

Background Homozygous familial hypercholesterolemia (hoFH) is a rare genetic disorder leading to extremely increased LDL-cholesterol (LDL-C), resulting in high cardiovascular risk in early childhood. Lipid apheresis (LA) is an effective treatment and should be started as early as possible to prevent premature cardiovascular events. As peripheral punctures in children can be challenging due to small vessels and anxiety, this study aimed to evaluate feasibility and safety of central venous catheters (CVCs) as vascular access for LA in young children with hoFH. Methods Retrospective analysis (2016-2019) on four children with hoFH aged 3-5 years, performing weekly or biweekly LA with a CVC. Results LDL-C decreased by> 60%. In three children, the use of a permanent CVC for 698, 595, and 411 days, respectively, avoided difficult peripheral access, without the occurrence of occlusion or thrombosis. Unfortunately, one child had recurrent CVC-related infections and needed an arteriovenous fistula from the age of 5. Although the mean dwell time per catheter was 212 days, there were, as expected, severe side effects of early catheter infections with sepsis and accidental self-removal. Starting LA at an early age improved or stabilized carotid intima-media thickness (IMT) in three children. However, IMT did increase in one child caused by intolerance to peripheral punctures and LA interruption. Conclusions Permanent CVCs are a viable temporary access choice for LA in young children with hoFH until peripheral venipuncture is practicable. The risk of CVC-related infections needs to be taken into account.

Background There are no studies that have specifically investigated the cost-effectiveness of cascade screening of children for heterozygous familial hypercholesterolemia (FH) and treatment of affected individuals with statins to prevent coronary heart disease (CHD). Purpose This study explores the cost-effectiveness of this strategy from the perspective of the Australian public healthcare system. Methods A lifetime Markov model with four health states (Alive without CHD, Alive with CHD, Dead from fatal CHD, and Dead from other causes) was developed to simulate the progression of ten- year-old children screened for FH and treated immediately with statins if found to have FH. The underlying prevalence of FH in this target population was assumed to be 56.8%, and the sensitivity and specificity of testing was 100%. The comparator was usual care, which assumed that subjects started statins spontaneously at a later point or when they experienced a cardiovascular event. The effect of reducing low-density lipoprotein cholesterol (LDL-C) on the risk of a first event at each age assumed that risk was proportional to total lifetime exposure and was implemented using Mendelian randomisation analysis data. Cost and other outcome data were sourced from published sources. Outcome of interests were costs in Australian dollars (AUD), life years gained (LYG) and quality-adjusted life years (QALYs) gained, as well as incremental cost-effectiveness ratios (ICERs) of costs per LYG and per QALY gained. All future costs and outcomes were discounted by 5% annually. Results Undiscounted results showed that compared with usual care, cascade screening of ten year-old children for FH and initiation of treatment of affected individuals saved 7.77 LYG and 7.53 QALYs per person over a lifetime. With 5% annual discounting, there were 0.97 LYG and 1.07 QALYs gained per person, at an additional cost of $3,244. These equated to ICERs of $3334 per LYG and $3023 per QALY gained. The equivalent ICERs in USD would be $5089 per LYG gained and $4615 per QALY gained. Sensitivity analysis showed the results to be robust. Conclusions Compared to usual care, cascade screening of ten year old children for FH and treating affected individuals is likely to be highly cost-effective. Table 1.

Background and aims: Homozygous familial hypercholesterolemia (hoFH) may cause life-threatening atherosclerotic cardiovascular disease in childhood. Lipoprotein apheresis (LA) is considered a pivotal treatment option, but data on its efficacy, safety and optimal performance are limited. We therefore established an international registry on the execution and outcomes of LA in HoFH children. Here we report LA policies and short-term outcomes. Methods: We approached centers worldwide, involved in LA in children with hoFH for participation. We collected information on clinical and treatment characteristics on patients aged 0–19 years between November 2016 and November 2018. Results: We included 50 children, treated at 15 sites. Median (IQR) LDL-C levels at diagnosis, on medication and on LA were 19.2 (16.2–22.1), 14.4 (10.8–16.7) mmol/L and 4.6 mmol/L, respectively. Median (IQR) time between diagnosis and start of LA was 2.8 (1.0–4.7) years. Six (12%) patients developed cardiovascular disease during that period. Most children received LA either weekly (43%) or biweekly (37%). Seven (17%) patients reached mean LDL-C levels

Background and aims For children with heterozygous familial hypercholesterolaemia (HeFH), European guidelines recommend consideration of statin therapy by age 8–10 years for those with a low density lipoprotein cholesterol (LDL-C) >3.5 mmol/l, and dietary and lifestyle advice. Here we compare the characteristics and lipid levels in HeFH children from Norway, UK, Netherlands, Belgium, Czech Republic, Austria, Portugal and Greece. Methods Fully-anonymized data were analysed at the London centre. Differences in registration and on treatment characteristics were compared by standard statistical tests. Results Data was obtained from 3064 children. The median age at diagnosis differed significantly between countries (range 3–11 years) reflecting differences in diagnostic strategies. Mean (SD) LDL-C at diagnosis was 5.70 (±1.4) mmol/l, with 88% having LDL-C>4.0 mmol/l. The proportion of children older than 10 years at follow-up who were receiving statins varied significantly (99% in Greece, 56% in UK), as did the proportion taking Ezetimibe (0% in UK, 78% in Greece). Overall, treatment reduced LDL-C by between 28 and 57%, however, in those >10 years, 23% of on-treatment children still had LDL-C>3.5 mmol/l and 66% of those not on a statin had LDL-C>3.5 mmol/l. Conclusions The age of HeFH diagnosis in children varies significantly across 8 countries, as does the proportion of those >10 years being treated with statin and/or ezetimibe. Approximately a quarter of the treated children and almost three quarters of the untreated children older than 10 years still have LDL-C concentrations over 3.5 mmol/l. These data suggest that many children with FH are not receiving the full potential benefit of early identification and appropriate lipid-lowering treatment according to recommendations., Graphical abstract Image 1, Highlights • The age of HeFH diagnosis varies significantly between 8 European countries. • The proportion of HeFH children being treated varies across 8 European countries. • A quarter of FH children on statins have LDL-C above the target (>3.5 mmol/L). • Many FH children are not getting the full benefit of early diagnosis and treatment.

Background: Impaired cognition can be a late effect after treatment in long-term testicular cancer (TC) survivors, negatively affecting their daily life. However, little data is available beyond 20 years post-treatment. We assessed cognitive impairment in very long-term TC survivors after CT or RT and compared the results with stage I TC survivors and controls. Methods: In this cross-sectional multicenter cohort study, we enrolled TC survivors (treated with orchiectomy followed by CT or RT or orchiectomy only)—with a follow-up duration ≥ 20 years—and age-matched healthy controls. Cognitive testing included the Auditory Verbal Learning Test, Letter Fluency Test, Category Fluency Test, and Trail Making Test. We used fasting blood samples to assess the presence of hypogonadism and measured cardiovascular aging parameters, including carotid pulse wave velocity (c-PWV) and advanced glycation end products (AGEs). Results: We included 184 TC survivors (66 CT patients, 53 RT patients, and 65 orchiectomy-only patients) and 70 healthy controls. The median follow-up was 26 years (range: 20–42). TC survivors had a lower combined score of the cognitive tests (mean cumulative Z-score −0.85, 95% CI −1.39 to −0.33) compared to controls (mean 0.67, 95% CI −0.21 to 1.57, p &lt, 0.01). In univariate analysis, the presence of hypogonadism (β −1.50, p &lt, 0.01), high c-PWV (β −0.35, p = 0.09), and high AGEs (β −1.27, p = 0.02) were associated with lower cognitive scores, while only AGEs (β −1.17, p = 0.03) remained a significant predictor in multivariate analysis (Model R2 0.31, p &lt, 0.01). Conclusions: Long-term TC survivors performed worse on cognitive tests compared to controls. Physicians and patients should be informed about timely cardiovascular risk management and testosterone supplementation therapy during follow-up to reduce the risk of cognitive impairment.

The genetic screening program for familial hypercholesterolemia (FH) in the Netherlands, which was embraced by the Dutch Ministry of Health from 1994 to 2014, has led to twenty years of identification of at least 1500 FH cases per year. Although funding by the government was terminated in 2014, the approach had proven its effectiveness and had built the foundation for the development of more sophisticated diagnostic tools, clinical collaborations, and new molecular-based treatments for FH patients. As such, the community was driven to continue the program, insurance companies were convinced to collaborate, and multiple approaches were launched to find new index cases with FH. Additionally, the screening was extended, now also including other heritable dyslipidemias. For this purpose, a diagnostic next-generation sequencing (NGS) panel was developed, which not only comprised the culprit LDLR, APOB, and PCSK9 genes, but also 24 other genes that are causally associated with genetic dyslipidemias. Moreover, the NGS technique enabled further optimization by including pharmacogenomic genes in the panel. Using such a panel, more patients that are prone to cardiovascular diseases are being identified nowadays and receive more personalized treatment. Moreover, the NGS output teaches us more and more about the dyslipidemic landscape that is less straightforward than we originally thought. Still, continuous progress is being made that underlines the strength of genetics in dyslipidemia, such as discovery of alternative genomic pathogenic mechanisms of disease development and polygenic contribution.

Background: Homozygous familial hypercholesterolemia (HoFH) is a rare genetic disorder that may cause life-threatening cardiovascular disease (CVD) at childhood. Marginal effectiveness of statins in reducing low-density lipoprotein cholesterol (LDL-C) is the reason why extracorporeal removal of LDL-C by lipoprotein apheresis (LA) is recommended at the earliest possible age. Objective: It is, however, unknown to what extent LA effectively reduces the burden of CVD in children with HoFH. We therefore systemically reviewed the literature on the efficacy and safety of LA in children with HoFH. Methods: We conducted a systematic literature search using Embase Classic and Embase on studies that evaluated LA in patients with HoFH aged

Background and aims: Familial hypercholesterolaemia (FH) is commonly caused by mutations in the LDLR, APOB or PCSK9 genes, with untreated mean low density lipoprotein-cholesterol (LDL-C) concentrations being elevated in APOB mutation carriers, even higher in LDLR mutation and highest in those with a PCSK9 mutation. Here we examine this in children with FH from Norway, UK, The Netherlands, Belgium, Czech Republic, Austria, Portugal and Greece. Methods: Differences in characteristics and pre- and post-treatment lipid concentrations in those with different molecular causes were compared by standard statistical tests. Results: Data were obtained from 2866 children, of whom 2531 (88%) carried a reported LDLR/APOB/PCSK9 variant. In all countries, the most common cause of FH was an LDLR mutation (79% of children, 297 different), but the prevalence of the APOB p.(Arg3527Gln) mutation varied significantly (ranging from 0% in Greece to 39% in Czech Republic, p < 2.2 × 10-16). The prevalence of a family history of premature CHD was significantly higher in children with an LDLR vs APOB mutation (16% vs 7% p=0.0005). Compared to the LDLR mutation group, mean (±SD) concentrations of pre-treatment LDL-C were significantly lower in those with an APOB mutation (n = 2260 vs n = 264, 4.96 (1.08)mmol/l vs 5.88 (1.41)mmol/l, p < 2.2 × 10-16) and lowest in those with a PCSK9 mutation (n = 7, 4.71 (1.22)mmol/l). Conclusions: The most common cause of FH in children from eight European countries was an LDLR mutation, with the prevalence of the APOB p.(Arg3527Gln) mutation varying significantly across countries. In children, LDLR-FH is associated with higher concentrations of LDL-C and family history of CHD compared to those with APOB-FH. Highlights: LDLR mutations are the most common cause of familial hypercholesterolaemia (FH) in children from 8 European countries; Overall, 279 different LDLR mutations were found in 2531 FH children; The frequency of APOB p.(Arg3527Gln) varied significantly over the 8 countries; APOB-FH was less severe than LDLR-FH for low density lipoprotein-cholesterol (LDL-C) concentration and family onset of coronary heart disease (CHD).

Background and aims Both plasma low-density lipoprotein (LDL) cholesterol levels and risk for premature cardiovascular disease are extremely elevated in patients with homozygous familial hypercholesterolemia (HoFH), despite the use of multiple cholesterol lowering treatments. Given its inborn nature, atherosclerotic plaques are commonly observed in young HoFH patients. Whether intensive lipid lowering strategies result in plaque regression in adolescent patients is unknown. Methods Two HoFH patients with null/null LDLR variants, who participated in the R1500-CL-1629 randomized clinical trial (NCT03399786) evaluating the LDL cholesterol lowering effect of evinacumab (a human antibody directed against ANGPTL3; 15 mg/kg intravenously once monthly), were included in this study. Patients underwent coronary computed tomography angiography (CCTA) before randomization and after 6 months of treatment. Results Both patient A (aged 12) and B (aged 16) were treated with a statin, ezetimibe and weekly apheresis. Evinacumab decreased mean pre-apheresis LDL cholesterol levels from 5.51 ± 0.75 and 5.07 ± 1.45 mmol/l to 2.48 ± 0.31 and 2.20 ± 0.13 mmol/l and post-apheresis LDL levels from 1.45 ± 0.26 and 1.37 ± 39 mmol/l to 0.80 ± 0.16 and 0.78 ± 0.13 mmol/l in patient A and B, respectively. Total plaque volumes were reduced by 76% and 85% after 6 months of evinacumab treatment in patient A and B, respectively. Conclusions We describe two severely affected young HoFH patients in whom profound plaque reduction was observed with CCTA after intensive lipid lowering therapy with statins, ezetimibe, LDL apheresis, and evinacumab. This shows that atherosclerotic plaques possess the ability to regress at young age, even in HoFH patients.

Background Mitochondrial damage and dysfunction have been reported in airway and quadriceps muscle cells of patients with chronic obstructive pulmonary disease (COPD). We determined the concomitance of mitochondrial dysfunction in these cells in COPD. Methods Bronchial biopsies were obtained from never- and ex-smoker volunteers and COPD patients (GOLD Grade 2) and quadriceps muscle biopsies from the same volunteers in addition to COPD patients at GOLD Grade 3/4 for measurement of mitochondrial function. Results Decreased mitochondrial membrane potential (ΔΨm), increased mitochondrial reactive oxygen species (mtROS) and decreased superoxide dismutase 2 (SOD2) levels were observed in mitochondria isolated from bronchial biopsies from Grade 2 patients compared to healthy never- and ex-smokers. There was a significant correlation between ΔΨm and FEV1 (% predicted), transfer factor of the lung for carbon monoxide (TLCOC % predicted), 6-min walk test and maximum oxygen consumption. In addition, ΔΨm was also associated with decreased expression levels of electron transport chain (ETC) complex proteins I and II. In quadriceps muscle of Grade 2 COPD patients, a significant increase in total ROS and mtROS was observed without changes in ΔΨm, SOD2 or ETC complex protein expression. However, quadriceps muscle of GOLD Grade 3/4 COPD patients showed an increased mtROS and decreased SOD2 and ETC complex proteins I, II, III and V expression. Conclusions Mitochondrial dysfunction in the airways, but not in quadriceps muscle, is associated with airflow obstruction and exercise capacity in Grade 2 COPD. Oxidative stress-induced mitochondrial dysfunction in the quadriceps may result from similar disease processes occurring in the lungs.

Background: Evolocumab, a fully human monoclonal antibody directed against proprotein convertase subtilisin-kexin type 9, is widely used in adult patients to lower low-density lipoprotein (LDL) cholesterol levels. Its effects in pediatric patients with heterozygous familial hypercholesterolemia are not known. Methods: We conducted a 24-week, randomized, double-blind, placebo-controlled trial to evaluate the efficacy and safety of evolocumab in pediatric patients with heterozygous familial hypercholesterolemia. Patients 10 to 17 years of age who had received stable lipid-lowering treatment for at least 4 weeks before screening and who had an LDL cholesterol level of 130 mg per deciliter (3.4 mmol per liter) or more and a triglyceride level of 400 mg per deciliter (4.5 mmol per liter) or less were randomly assigned in a 2:1 ratio to receive monthly subcutaneous injections of evolocumab (420 mg) or placebo. The primary end point was the percent change in LDL cholesterol level from baseline to week 24; key secondary end points were the mean percent change in LDL cholesterol level from baseline to weeks 22 and 24 and the absolute change in LDL cholesterol level from baseline to week 24. Results: A total of 157 patients underwent randomization and received evolocumab (104 patients) or placebo (53 patients). At week 24, the mean percent change from baseline in LDL cholesterol level was -44.5% in the evolocumab group and -6.2% in the placebo group, for a difference of -38.3 percentage points (P

Aim: Children with Familial Hypercholesterolemia (FH) are widely prescribed statins, and it has been suggested that the effects of statins differ among ethnicities. We compared the efficacy and safety of pitavastatin in children and adolescents with FH in clinical trials conducted in Japan and Europe. Methods: Low-density lipoprotein cholesterol (LDL-C) reductions, adjusted for confounding factors, and safety were compared between the studies in Japan and Europe. In the Japanese study, 14 males with heterozygous FH, aged 11.8 ± 1.6 years, were randomized to 52-week double-blind treatment with 1 or 2 mg/day pitavastatin. In the European study, 106 children and adolescents with high risk hyperlipidemia (103 heterozygous FH), aged 10.6 ± 2.9 years, were randomized to 12-week double-blind treatment with 1, 2 or 4 mg/day pitavastatin or placebo; 84 of these patients and 29 new patients participated in a 52-week open-label extension study. Results: Age, body weight and baseline LDL-C were identified as factors influencing LDL-C reduction. There were no significant differences in the adjusted mean percentage reduction in LDL-C in Japanese and European children by pitavastatin (24.5% and 23.6%, respectively at 1 mg/day and 33.5% and 30.8%, respectively at 2 mg/day). Pitavastatin was well tolerated without any difference in the frequency or nature of adverse events between the treatment groups, or between the studies. Conclusion: There were no significant differences between the efficacy or safety of pitavastatin in Japanese and European children and adolescents with FH, suggesting no relevant ethnic differences in the safety or efficacy of pitavastatin.

BACKGROUND: Atherosclerosis starts in childhood and its progression is influenced by lifelong low-density lipoprotein cholesterol (LDL-c) exposure, the so-called cholesterol burden. Early identification of children and adolescents with severely elevated LDL-c is thus of major clinical significance. This is especially true for children with familial hypercholesterolemia (FH), a frequent but undertreated genetic disorder. To identify children with possible FH, insight in the distribution of lipid levels in children is a prerequisite.OBJECTIVE: To provide health care professionals with contemporary age- and gender-based pediatric reference values for lipid and lipoprotein levels to help the identification of children with dyslipidemia, especially FH.METHODS: Lifelines is a large prospective population-based Dutch cohort study. Children from 8 till 18 years of age were included and fasting lipid levels were measured. Smoothed reference curves and percentiles (5th, 10th, 25th, 50th, 7th, 90th, and 95th) were generated using the Generalized Additive Models for Location, Scale and Shape package in the statistical software R.RESULTS: A total of 8071 children (3823 boys and 4248 girls) were included. In the total cohort we noted marked dynamic changes in lipid and lipoprotein levels over age, which were in part gender specific. Our data highlight a high and unexpected prevalence of severely elevated LDL-c (>190 mg/dL) in both boys and girls.CONCLUSION: Our cross-sectional data provide contemporary reference ranges for plasma lipids that can assist physicians in identifying children at increased risk of premature atherosclerosis, especially FH.

Background: Quality registries play an important role in the professional quality system for cancer treatment in The Netherlands. This article provides insight into the Dutch Lung Cancer Audit (DLCA); its core principles, initiation and development, first results and what lessons can be learned from the Dutch experience. Methods: Cornerstones of the DLCA are discussed in detail, including: audit aims; the leading role for clinicians; web-based registration and feedback; data handling; multidisciplinary evaluation of quality indicators; close collaborations with all stakeholders in healthcare and transparency of results. Results: In 2012 the first Dutch lung cancer specific sub-registry, focusing on surgical treatment was started. Since 2016 all major treating specialisms (lung oncologists, radiation-oncologists, general- and cardiothoracic surgeons—represented in the DLCA-L, -R and -S sub-registries respectively) have joined. Over time, the number of participating hospitals and included patients has increased. In 2016, the numbers of included patients with a non-small cell lung cancer (NSCLC) were 3,502 (DLCA-L), 2,427 (DLCA-R) and 1,979 (DLCA-S). Between sub-registries mean age varied from 66 to 70 years, occurrence of Eastern Cooperative Oncology Group (ECOG) performance score 2+ varied from 3.3% to 20.8% and occurrence of clinical stage I–II from 27.6% to 81.3%. Of all patients receiving chemoradiotherapy 64.2% was delivered concurrently. Of the surgical procedures 71.2% was started with a minimally invasive technique, with a conversion rate of 18.7%. In 2016 there were 17 publicly available quality indicators—consisting of structure, process and outcome indicators- calculated from the DLCA. Conclusions: the DLCA is a unique registry to evaluate the quality of multidisciplinary lung cancer care. It is accepted and implemented on a nationwide level, enabling participating healthcare providers to get insight in their performance, and providing other stakeholders with a transparent evaluation of this performance, all aiming for continuous healthcare improvement.

Reduced vital capacity (VC) and forced vital capacity (FVC) are associated with lead (Pb) exposure.The objective of this study is to analyse the effects of Pb on FVC and the shuttle run performance.Data were available for 184 male and 189 female Polish schoolchildren aged 10-15 years. Regression analysis was performed of shuttle run performance (dependent) on Pb and FVC.Shuttle run time increased by 1.75 (± 0.77) and 1.97 (± 0.77) seconds for each 10 µg/dL increase in Pb blood among males and females, respectively. Higher shuttle run times indicate poorer performance. Average unadjusted blood Pb level in the sample was 5.27 μg/dL (± 0.19 SE) and 3.82 μg/dL (± 0.10 SE), respectively. Path analysis was used to assess the association of Pb level with shuttle run time. Blood Pb had a significant negative effect on VC (B= -13.60 ± 3.28 [SE], p 0.0001) and FVC (B = -13.08 ± 3.27, p 0.0001). FVC had a small but significant effect on shuttle run time (B = -0.04 ± 0.007, p 0.0001). Pb had a significant effect on the residual of shuttle run time among males (B = 1.59 ± 0.75, p 0.03) and females after the effect of FVC was removed (B = 1.49 ± 0.73, p 0.04).Thus, Pb had direct and indirect effects that increased shuttle run time, i.e. negatively affected performance.

BACKGROUND Homozygous familial hypercholesterolemia (HoFH), a rare genetic disorder, is characterized by extremely elevated levels of low-density lipoprotein cholesterol (LDL-C) and accelerated atherosclerotic cardiovascular disease. Statin treatment starts at diagnosis, but no statin has been formally evaluated in, or approved for, HoFH children. OBJECTIVES The authors sought to assess the LDL-C efficacy of rosuvastatin versus placebo in HoFH children, and the relationship with underlying genetic mutations. METHODS This was a randomized, double-blind, 12-week, crossover study of rosuvastatin 20 mg versus placebo, followed by 12 weeks of open-label rosuvastatin. Patients discontinued all lipid-lowering treatment except ezetimibe and/or apheresis. Clinical and laboratory assessments were performed every 6 weeks. The relationship between LDL-C response and genetic mutations was assessed by adding children and adults from a prior HoFH rosuvastatin trial. RESULTS Twenty patients were screened, 14 randomized, and 13 completed the study. The mean age was 10.9 years; 8 patients were on ezetimibe and 7 on apheresis. Mean LDL-C was 481 mg/dl (range: 229 to 742 mg/dl) on placebo and 396 mg/dl (range: 130 to 700 mg/dl) on rosuvastatin, producing a mean 85.4 mg/dl (22.3%) difference (p = 0.005). Efficacy was similar regardless of age or use of ezetimibe or apheresis, and was maintained for 12 weeks. Adverse events were few and not serious. Patients with 2 defective versus 2 negative LDL receptor mutations had mean LDL-C reductions of 23.5% (p = 0.0044) and 14% (p = 0.038), respectively. CONCLUSIONS This first-ever pediatric HoFH statin trial demonstrated safe and effective LDL-C reduction with rosuvastatin 20 mg alone or added to ezetimibe and/or apheresis. The LDL-C response in children and adults was related to underlying genetic mutations.

Background: Heterozygous familial hypercholesterolemia (HeFH) is an autosomal dominant disorder leading to premature atherosclerosis. Children with HeFH exhibit early signs of atherosclerosis manifested by increased carotid intima-media thickness (IMT). In this study, we assessed the effect of 2-year treatment with rosuvastatin on carotid IMT in children with HeFH. Methods: Children with HeFH (age, 6–4.9 mmol/L or >4.1 mmol/L in combination with other risk factors received rosuvastatin for 2 years, starting at 5 mg once daily, with uptitration to 10 mg (age, 6–P values were adjusted for age, sex, carotid artery site, and family relations. Results: At baseline, mean±SD carotid IMT was significantly greater for the 197 children with HeFH compared with the 65 unaffected siblings (0.397±0.049 and 0.377±0.045 mm, respectively; P =0.001). During 2 years of follow-up, the change in carotid IMT was 0.0054 mm/y (95% confidence interval, 0.0030–0.0082) in children with HeFH and 0.0143 mm/y (95% confidence interval, 0.0095–0.0192) in unaffected siblings ( P =0.002). The end-of-study difference in mean carotid IMT between children with HeFH and unaffected siblings after 2 years was no longer significant (0.408±0.043 and 0.402±0.042 mm, respectively; P =0.2). Conclusions: In children with HeFH who were ≥6 years of age, carotid IMT was significantly greater at baseline compared with unaffected siblings. Rosuvastatin treatment for 2 years resulted in significantly less progression of increased carotid IMT in children with HeFH than untreated unaffected siblings. As a result, no difference in carotid IMT could be detected between the 2 groups after 2 years of rosuvastatin. These findings support the value of early initiation of statin treatment for low-density lipoprotein cholesterol reduction in children with HeFH.

Background Patients with autosomal dominant hypercholesterolemia (ADH), caused by mutations in either low-density lipoprotein receptor ( LDLR ), apolipoprotein B ( APOB ), or proprotein convertase subtilisin-kexin type 9 ( PCSK9 ) are characterized by high low-density lipoprotein cholesterol levels and in some studies also high lipoprotein(a) (Lp(a)) levels were observed. The question remains whether this effect on Lp(a) levels is gene-dose–dependent in individuals with either 0, 1, or 2 LDLR or APOB mutations. Objective We set out to study whether Lp(a) levels differ among bi-allelic ADH mutation carriers, and their relatives, in the Netherlands. Methods Bi-allelic ADH mutation carriers were identified in the database of the national referral laboratory for DNA diagnostics of inherited dyslipidemias. Family members were invited by the index cases to participate. Clinical parameters and Lp(a) levels were measured in bi-allelic ADH mutation carriers and their heterozygous and unaffected relatives. Results We included a total of 119 individuals; 34 bi-allelic ADH mutation carriers (20 homozygous/compound heterozygous LDLR mutation carriers (HoFH), 2 homozygous APOB mutation carriers (HoFDB), and 12 double heterozygotes for an LDLR and APOB mutation), 63 mono-allelic ADH mutation carriers (50 heterozygous LDLR [HeFH], 13 heterozygous APOB [HeFDB] mutation carriers), and 22 unaffected family members. Median Lp(a) levels in unaffected relatives, HeFH, and HoFH patients were 19.9 (11.1–41.5), 24.4 (5.9–70.6), and 47.3 (14.9–111.7) mg/dL, respectively ( P = .150 for gene-dose dependency). Median Lp(a) levels in HeFDB and HoFDB patients were 50.3 (18.7–120.9) and 205.5 (no interquartile range calculated), respectively ( P = .012 for gene-dose-dependency). Double heterozygous carriers of LDLR and APOB mutations had median Lp(a) levels of 27.0 (23.5–45.0), which did not significantly differ from HoFH and HoFDB patients ( P = .730 and .340, respectively). Conclusion A (trend toward) increased plasma Lp(a) levels in homozygous ADH patients compared with both heterozygous ADH and unaffected relatives was observed. Whether increased Lp(a) levels in homozygous ADH patients add to the increased cardiovascular disease risk and whether this risk can be reduced by therapies that lower both low-density lipoprotein cholesterol and Lp(a) levels remains to be elucidated.

Background: Mepolizumab treatment improves asthma outcomes in the majority but not all patients with severe eosinophilic asthma. Baseline patient characteristics may influence mepolizumab induced outcomes, but it is difficult to assess individuals’ chance of being a responder. Assessment of early treatment response may add in the prediction of long-term benefit. Aim: To examine the relationship between mepolizumab induced asthma control at 8 weeks and the chance of being mepolizumab responder at 32 weeks. Methods: 20 severe asthma patients that started with mepolizumab were evaluated on baseline and 8, 16 and 32 weeks. We compared therapy response, defined as continuing mepolizumab therapy at 32 weeks, in patients with and without good asthma control (ACQ≤0.75) at 8 weeks. Results: Of the 20 included patients (median age 52 years (range 28-76), 50% male, 70% OCS dependent), 16 patients (80%) continued mepolizumab therapy at 32 weeks after initiation (responders). Median ACQ decreased from 2.42 (0.67–4.33) at baseline to 0.75 (0.0-3.33) after 8 weeks of therapy (p 0.75 at 8 weeks(negative predictive value=40%)(RR 1.7, 95%CI 1.005-2.765; P=0.043). Conclusions: Patients who show good asthma control at 8 weeks of mepolizumab treatment have a very high chance of therapy response at 32 weeks. These data suggest that early treatment responses may be helpful to identify patients that benefit from biologicals in the long-term.

Background: Eosinophilic asthma may be complicated by chronic rhinosinusitis (CRS) or eosinophilic otitis with subsequent hearing loss. Anti-IL5 treatment improves asthma in many patients with severe eosinophilic asthma. It is unknown whether in these patients symptoms of CRS or otitis are reduced following anti-IL5 treatment. Aim: To evaluate symptom scores of CRS and otitis in patients with severe asthma in the first 16 weeks of anti-IL5 treatment. Methods: In this prospective cohort study we included patients that started with anti-IL5 treatment (mepolizumab, reslizumab, benralizumab). Severity of CRS, otitis and hearing loss was assessed using Borg scores at baseline and 16 weeks. Results: We included 31 asthma patients (61% adult-onset, 29% atopic, 65% with known CRS/polyposis, 83% on daily OCS). At baseline, 20/31 patients reported any level of symptoms (Borg>0) for CRS, 6/31 for otitis and 7/31 for hearing loss. After 16 weeks, in the total group ACQ improved by 0.8 points (SD=0.9, p 0.20). However, within patients with symptoms at baseline, there was a significant improvement in otitis symptoms (Borg score median (IQR) from 1 (0.5-7) to 0 (0-4), p=0.03) and a trend for less hearing loss (from 4 (0.5-5) to 1.75 (0-5), p=0.07). Conclusions: Despite good effect on asthma control, anti-IL5 treatment did not improve CRS symptoms, but had some effect on symptoms of otitis and hearing loss. These results question the role of IL5 in CRS inflammation and at the same time support the idea of eosinophilic otitis representing an additional phenotypic feature of severe eosinophilic asthma.

Background and aims Homozygous familial hypercholesterolemia (hoFH) is a rare genetic disease, hallmarked by a lifelong exposure to very high levels of low-density lipoprotein cholesterol (LDL-C). Untreated, patients can experience a cardiovascular event in the first decade of life. Early detection and monitoring of subclinical atherosclerosis in these patients is therefore extremely important. We set out to assess the diagnostic yield of low-dose coronary computed tomography angiography (cCTA) compared to echocardiography in detecting subclinical atherosclerosis. Methods For this single-center cross-sectional study, we included all pediatric hoFH patients treated with lipoprotein-apheresis (LA) in Amsterdam UMC. We performed both cCTA and echocardiography in all patients as part of routine follow-up. Results Six hoFH patients were included. Median ages at diagnosis, onset of LA and cardiovascular assessment (cCTA and echocardiography) were 2.6, 6.5, 10.8 and 11.1 years, respectively. Echocardiography revealed no signs of atherosclerosis in any of the six patients. In two patients, mild dilatation of the cardiac chambers was detected and two patients showed signs of mitral or aortic insufficiency. On cCTA, however, non-calcified plaques without stenosis were detected in four patients. In two patients calcified coronary plaques were found at the ostia of the right coronary artery or the left main coronary artery. Aortic root calcifications were found in two patients. Conclusions Our findings suggest that in hoFH children, low-dose cCTA is superior to echocardiography for the detection of subclinical coronary and aortic root atherosclerosis and should therefore be considered in the routine cardiovascular monitoring of these high-risk children.

Neoadjuvant treatment consisting of five cycles of carboplatin and paclitaxel with concurrent radiotherapy (41.4 Gy), followed by esophagectomy, is the standard treatment for resectable esophageal cancer in The Netherlands. It remains unclear whether intensification of neoadjuvant therapy leads to better outcomes. This study analyzed the outcomes of intensified chemoradiotherapy. We included patients who were deemed eligible for esophagectomy between January 2008 and December 2014. Neoadjuvant therapy consisted of six cycles of carboplatin (area under the curve = 2 mg/mL/min) and paclitaxel (50 mg/m2 of body surface area) and concurrent radiotherapy (50.4 Gy administered in 28 fractions of 1.8 Gy each, 5 days per week), followed by esophagectomy. Of the 176 patients included in this study, 73% underwent a resection. At a median follow-up of 29.3 months for the total cohort, median disease-free survival (DFS) was 22.5 months. DFS at 3 and 5 years was 42% and 36%, respectively, while the overall survival (OS) rates were 47% and 38%, respectively. In addition, the 5-year DFS and OS rates of our resection group were 44% and 48%, respectively. In 102 patients (58%), grade 3 or higher adverse events were observed, mainly hematological. The postoperative mortality rate within 30 days was 4%, and pathological complete response was achieved in 35% of patients. Intensification of neoadjuvant chemoradiotherapy for patients with potentially resectable esophageal cancer is well tolerated, yielding high pathological complete response rates, but adverse events occurred frequently, and survival compared with conventional neoadjuvant chemoradiotherapy seems similar. Therefore, intensification of neoadjuvant chemoradiotherapy should not be routinely used.

BACKGROUND Familial hypercholesterolemia is characterized by severely elevated low-density lipoprotein (LDL) cholesterol levels and premature cardiovascular disease. The short-term efficacy of statin therapy in children is well established, but longer follow-up studies evaluating changes in the risk of cardiovascular disease are scarce. METHODS We report a 20-year follow-up study of statin therapy in children. A total of 214 patients with familial hypercholesterolemia (genetically confirmed in 98% of the patients), who were previously participants in a placebo-controlled trial evaluating the 2-year efficacy and safety of pravastatin, were invited for follow-up, together with their 95 unaffected siblings. Participants completed a questionnaire, provided blood samples, and underwent measurements of carotid intima-media thickness. The incidence of cardiovascular disease among the patients with familial hypercholesterolemia was compared with that among their 156 affected parents. RESULTS Of the original cohort, 184 of 214 patients with familial hypercholesterolemia (86%) and 77 of 95 siblings (81%) were seen in follow-up; among the 214 patients, data on cardiovascular events and on death from cardiovascular causes were available for 203 (95%) and 214 (100%), respectively. The mean LDL cholesterol level in the patients had decreased from 237.3 to 160.7 mg per deciliter (from 6.13 to 4.16 mmol per liter)-a decrease of 32% from the baseline level; treatment goals (LDL cholesterol

Item does not contain fulltext AIMS: Homozygous familial hypercholesterolaemia (HoFH) is a rare life-threatening condition characterized by markedly elevated circulating levels of low-density lipoprotein cholesterol (LDL-C) and accelerated, premature atherosclerotic cardiovascular disease (ACVD). Given recent insights into the heterogeneity of genetic defects and clinical phenotype of HoFH, and the availability of new therapeutic options, this Consensus Panel on Familial Hypercholesterolaemia of the European Atherosclerosis Society (EAS) critically reviewed available data with the aim of providing clinical guidance for the recognition and management of HoFH. METHODS AND RESULTS: Early diagnosis of HoFH and prompt initiation of diet and lipid-lowering therapy are critical. Genetic testing may provide a definitive diagnosis, but if unavailable, markedly elevated LDL-C levels together with cutaneous or tendon xanthomas before 10 years, or untreated elevated LDL-C levels consistent with heterozygous FH in both parents, are suggestive of HoFH. We recommend that patients with suspected HoFH are promptly referred to specialist centres for a comprehensive ACVD evaluation and clinical management. Lifestyle intervention and maximal statin therapy are the mainstays of treatment, ideally started in the first year of life or at an initial diagnosis, often with ezetimibe and other lipid-modifying therapy. As patients rarely achieve LDL-C targets, adjunctive lipoprotein apheresis is recommended where available, preferably started by age 5 and no later than 8 years. The number of therapeutic approaches has increased following approval of lomitapide and mipomersen for HoFH. Given the severity of ACVD, we recommend regular follow-up, including Doppler echocardiographic evaluation of the heart and aorta annually, stress testing and, if available, computed tomography coronary angiography every 5 years, or less if deemed necessary. CONCLUSION: This EAS Consensus Panel highlights the need for early identification of HoFH patients, prompt referral to specialized centres, and early initiation of appropriate treatment. These recommendations offer guidance for a wide spectrum of clinicians who are often the first to identify patients with suspected HoFH.

Background Homozygous familial hypercholesterolemia (hoFH) is either diagnosed on the identification of pathogenic genetic variants in LDLR, APOB, or PCSK9 or by phenotypic parameters of which an extremely elevated LDL-C level >13 mmol/L (>500 mg/dL) is the most prominent hallmark. Little is known about the clinical spectrum in children with hoFH. Objective We set out to investigate the phenotypical spectrum of genetically defined hoFH in our pediatric cohort and evaluated how many pediatric patients, now classified as heterozygous, carry a second mutation, which would reclassify these patients as hoFH. Methods We analyzed the data of a total of 1903 children with molecularly proven FH. Subsequently we performed candidate gene sequencing in the cohort of heterozygous familial hypercholesterolemia children in whom the LDL-C level was above the lowest level measured in the pediatric patients with hoFH. Results Of our 13 hoFH children, 8 (62%) had LDL-C levels below the clinical hoFH criteria of 13 mmol/L (500 mg/dL). In the remaining 1890 patients with heterozygous familial hypercholesterolemia, 64 (3.4%) had LDL-C levels equal to or above the lowest LDL-C level in a patient with hoFH carrying 2 deleterious variants (8.36 mmol/L or 323.3 mg/dL). No additional pathogenic variants in LDLR and APOB were identified. In 2 related patients, a PCSK9 gain of function mutation was found. Conclusion We show that LDL-C levels vary among pediatric patients with molecularly proven hoFH, and that most of these patients do not meet the clinical LDL-C criteria for hoFH. The levels overlap with LDL-C levels in true heterozygous patients. This warrants a critical reappraisal of the current LDL-C cutoffs for the phenotypic diagnosis of hoFH in children.

Purpose of Review: To create awareness for the devastating influence of high cholesterol in familial hypercholesterolaemia (FH) on vessel walls. Persons with high LDL-C and a known mutation associated with FH have a 22-fold increase in CVD compared with those with a normal LDL-C and no genetic mutation. If the awareness of the need to diagnose and treat this genetic disorder at an early stage increases, great atherosclerotic impact later in life could be avoided. Every minute a child with heterozygous FH is born somewhere in the world and every day a child with homozygous FH is born. Recent Findings: Recent findings include effective therapy on statins from the age of 6 years, with already normalization of the intima-media thickness within 2 years. Newer types of drugs, with the same safety profile and perhaps even more effective, will become available in childhood in the near future. Open for discussion will be whom to treat and with what type of treatment. Next generation sequencing will perhaps easily select those in need of treatment and those at risk of adverse effects. Summary: At the end of this review, statements and recommendations for children and adolescents with heterozygous FH are listed.

We appreciate the comments of Dr Koh regarding our recent publication in Circulation .1 We comment here on the issues raised. Undoubtedly, patients with heterozygous familial hypercholesterolemia (HeFH) should be treated with lipid-lowering medication from a young age to prevent premature cardiovascular disease. However, from what age exactly and to what extent low-density lipoprotein (LDL) cholesterol (LDL-C) should be lowered remain difficult questions, and the answers are probably different for each individual because many factors contribute to cardiovascular risk. From the baseline data of the CHARON trial (Hypercholesterolemia in Children and Adolescents Taking Rosuvastatin Open Label), the difference in carotid intima-media thickness (c-IMT) between subjects with HeFH and unaffected siblings was shown to be significant before the age of 8 years.2 This finding may suggest that statins should be started possibly from a younger age than is currently recommended because treatment should preferably be started before the process of atherosclerosis is detectable.

Background Evolocumab, a fully human monoclonal antibody to proprotein convertase subtilisin/kexin type 9, is safe and effective in reducing low-density lipoprotein cholesterol in adults with familial hypercholesterolemia. A dedicated study, HAUSER-RCT, is being conducted to examine the efficacy and safety of evolocumab in pediatric patients with heterozygous familial hypercholesterolemia (HeFH). Objective To present the rationale and design of the HAUSER-RCT study. Methods The HAUSER-RCT study is a double-blind, randomized, multicenter, placebo-controlled study designed to characterize the efficacy, safety, and tolerability of evolocumab treatment as an add-on to diet and lipid-lowering therapy, including a stable, optimized dose of statin, in pediatric patients aged 10 to 17 years with HeFH. Approximately, 150 patients will be randomized in a 2:1 ratio to receive 24 weeks of monthly evolocumab or placebo. The study will include approximately 51 sites located in North America, South America, Europe, South Africa, Australia, and New Zealand. The primary efficacy endpoint is the percent change in low-density lipoprotein cholesterol from baseline to week 24. A key secondary efficacy endpoint is the percent change in other lipid parameters from baseline to week 24. Other assessments include Tanner staging, carotid intima-media thickness, and cognitive tests. At the end of the study, consenting patients can participate in an 18-month open-label extension study (HAUSER-OLE). Results The study is ongoing and the results will be communicated at the end of the study. Conclusions The HAUSER-RCT study, the largest randomized, placebo-controlled study with proprotein convertase subtilisin/kexin type 9 inhibitors being conducted in the pediatric HeFH population, aims to provide efficacy, safety, and tolerability data of evolocumab as an add-on therapy in these patients.

Purpose To address the issue of physician maldistribution, some medical schools have rural-focused efforts, and many more are in the planning or early implementation stage. The best duration and structure of the rural immersion experience are unclear, and the relative effects of rural upbringing and rural training on subsequent rural practice choice are often difficult to determine. Methods To determine the effect of adding a rural clinical campus to our school, we analyzed the variables of rural upbringing, demographics, family medicine residency choice, and campus participation using a multivariate model for association with rural practice choice. We included graduates from the classes of 2001-2008 from both campuses (urban and rural) in the analysis. Findings We found similar associations to those reported previously of rural upbringing (OR = 2.67 [1.58-4.52]) and family medicine residency (OR = 5.08 [2.88-8.98]) with rural practice choice. Even controlling for these 2 variables, participation in the full 2 years at the rural clinical campus showed the strongest association (OR = 5.46 [2.61-11.42]). All 3 associations were significant at P < .001, and no other variables were significant. Conclusions We conclude that the investment of resources in our rural campus may add an increment to rural practice choice beyond the established associations with rural upbringing and family medicine residency. The decision of practice site choice is complex, and collaborative studies that include data from several schools with differently structured rural exposures, including those with rural clinical campuses, are needed.

AIMS: The first aim was to critically evaluate the extent to which familial hypercholesterolaemia (FH) is underdiagnosed and undertreated. The second aim was to provide guidance for screening and treatment of FH, in order to prevent coronary heart disease (CHD).METHODS AND RESULTS: Of the theoretical estimated prevalence of 1/500 for heterozygous FH, CONCLUSION: Owing to severe underdiagnosis and undertreatment of FH, there is an urgent worldwide need for diagnostic screening together with early and aggressive treatment of this extremely high-risk condition.

Purpose: Efforts to inform survivors about long-term risks and planned follow-up after cancer treatment have increased. Survivorship Care Plans (SCPs) and care planning sessions have been recommended since 2005, yet the benefits of both SCP provision and care planning are only now being assessed. The impact of SCPs separate from care planning sessions is unclear, however SCPs alone require less time and cost to provide than SCPs combined with care planning sessions. We hypothesized that SCPs alone might enhance patient knowledge. In a randomized trial, we assessed change in patient knowledge of diagnosis, treatment, late/chronic side effects and followup care pre and post receipt of SCP. Methods: Patients who completed primary treatment within the past 2 years for Stage 0-3 breast cancer were consented, enrolled, and randomized to immediate (intervention) versus delayed receipt (control) of an individualized SCP without care planning. All participants completed the Wisconsin Survey of DiagnOsis and Management in Breast cancer (WiSDOM-B), a test of knowledge about one’s own breast cancer diagnosis, treatment and late effects scored out of 40 points. The survey was completed at both baseline and at four weeks (prior to delayed receipt); the primary outcome was change in score. The study was designed with 90% power to detect a between-group difference of 4 points (out of 40 possible). Results: Between November 2013 and March 2014, we recruited 64 women aged 36-78 with Stage 0-3 breast cancer. Most participants were Stage 1-2 (n=50, 79%) with n=7 (10.9%) in Stage 3. Most had received chemotherapy (62.5%), endocrine therapy (89.1%), or radiation (76.6%). At baseline, the average WiSDOM-B score was 28.3 out of 40 (70.8%), range 15.5-38.5. There was no evidence of change in score from baseline to four weeks for either the immediate SCP group (+0.41, 95% CI [-0.97,+1.79]) or delayed receipt control group (+0.95, 95% CI [-0.48,2.38]). Observed variation was consistent with sample size assumptions, and the observed treatment difference (-0.55, 95% CI [-2.53,1.44], p=n.s.) ruled out the prespecified clinically significant effect size of +4.0 (+10%). Overall, participants scored better on questions testing knowledge of diagnosis (side, year of diagnosis, lymph node test results, receptor status, and stage) and surgical side effects than on questions testing knowledge of other treatment (chemotherapy, radiation or endocrine therapy) side effects. Participant satisfaction with knowledge and care team communication was collected pre and post SCP, as well as feedback on SCP content and use of the SCP. These and analyses of selected questions shown to change post SCP by Nissen et al will also be presented. Conclusion: In a controlled, randomized clinical trial, receipt of a SCP without care planning sessions did not appear to significantly increase survivor knowledge about cancer diagnosis, treatment and followup as assessed by the WiSDOM-B survey. Efforts to improve survivor knowledge should investigate the impact of care planning sessions or other interactive health information tools. A second study of patients (n=64) randomized to immediate or delayed receipt of SCPs, in conjunction with care planning sessions, is currently enrolling.

Background Statins are currently the preferred pharmacological therapy in individuals with familial hypercholesterolemia (FH) with the aim to prevent premature atherosclerosis. In adults, these agents have been proven to be safe and well tolerated; however, non-adherence is a significant clinical issue. Objectives In this study, we evaluated tolerability and adherence to statin therapy in young adult FH patients 10 years after this was initiated in their childhood. Methods A questionnaire including items on medical history, adherence and reasons for discontinuation was sent to 214 young adult FH patients that initiated statin therapy at least 10 years ago. Tolerability was defined as 100 % minus the percentage of patients that discontinued statin therapy due to side effects. Adherence was defined as the extent to which patients took their medication as prescribed by their physician. We labelled patients adherent if they took 80 % or more of their pills in the month preceding our assessment. Results Follow-up was successful in 205 (95.8 %) subjects (age 18–30 years). A history of side effects was reported by 40 (19.5 %) of the patients, and mainly consisted of muscle complaints and gastrointestinal symptoms. Three patients (1.5 %) discontinued statin therapy because of side effects. Rhadbomyolysis or other serious adverse events were not reported. In fact, 169 (82.4 %) of 205 patients remained on statin treatment and 78.7 % (148 out of 188) were adherent. None of the patient characteristics were significantly associated with adherence. Conclusions Individuals with FH who started statin therapy in childhood demonstrated good adherence during ten years of treatment. Furthermore, statin therapy was well tolerated; only a small minority discontinued therapy because of side effects and the side effects that were reported were mild in nature.

Item does not contain fulltext AIMS: Homozygous autosomal dominant hypercholesterolaemia (hoADH), an orphan disease caused by mutations in low-density lipoprotein receptor (LDLR), apolipoprotein B (APOB), or proprotein convertase subtilisin-kexin type 9 (PCSK9), is characterized by elevated plasma low-density lipoprotein-cholesterol (LDL-C) levels and high risk for premature cardiovascular disease (CVD). The exact prevalence of molecularly defined hoADH is unknown. Therefore, we investigated the prevalence and phenotypical characteristics of this disease in an open society, i.e. the Netherlands. METHODS AND RESULTS: The database of the nationwide ADH molecular diagnostic center was queried to identify all molecularly defined hoADH patients. Carriers of non-pathogenic mutations were excluded. Medical records were analysed for data regarding lipid levels and CVD events. Of 104 682 individuals screened for molecular defects, 49 were classified as hoADH (0.05%); 20 were true homozygotes, 25 were compound heterozygotes for LDLR mutations, and 4 were homozygous for APOB mutations. No bi-allelic PCSK9 mutation carriers were identified. Consequently, the prevalence of hoADH was estimated to be approximately 1 : 300 000. Mean LDL-C levels prior to lipid-lowering treatment were 12.9 +/- 5.1 mmol/L (range 4.4-21.5 mmol/L). Surprisingly, only 50% of the patients met the clinical criteria for hoADH (LDL-C >13.0 mmol/L); 29% of patients suffered from a CVD event. CONCLUSION: The prevalence of molecularly defined hoADH is much higher and the clinical phenotype is more variable than previously assumed. In light of the fact that novel therapies are, or will be registered for the treatment of hoADH patients, an uniform definition of hoADH either as a phenotypic or molecular entity is warranted in order to identify patients who are considered to be eligible for these novel agents.

BACKGROUND Kawasaki disease (KD) is an acute pediatric vasculitis with coronary artery aneurysms (CAA) as its main complication. Concerns have been raised regarding the possibility of a predisposition of KD to premature cardiovascular disease (CVD) risk later in life. Our aim was to assess carotid intima-media thickness (cIMT), as a surrogate marker of CVD risk, in patients with a history of KD compared with unaffected controls. METHODS AND RESULTS B-mode ultrasound cIMT measurements were performed in 168 patients with a history of KD, and 82 controls; 7 patients were excluded because of incomplete cIMT assessments. Mean cIMT (±SD) was increased in patients with KD compared with controls (0.378±0.030 mm vs. 0.360±0.027 mm, respectively; P adjusted

Familial hypercholesterolemia (FH) is a common genetic disorder that causes elevated LDL cholesterol levels from birth. Untreated FH accelerates atherosclerosis and predisposes individuals to premature coronary artery disease (CAD) in adulthood. Mendelian randomization studies have demonstrated that LDL cholesterol has both a causal and cumulative effect on the risk of CAD. This supports clinical recommendations that children with FH commence pharmacological treatment from the age of 8 to 10 years, to reduce the burden of hypercholesterolemia. Worldwide, the majority of children with FH remain undiagnosed. Recent evidence suggests that the frequency of FH is at least 1 in 250 and this constitutes a public health issue. We review and identify the knowns and unknowns concerning the detection and management of pediatric FH that impact on the developing model of care for this condition.- Martin, A. C., S. S. Gidding, A. Wiegman, and G. F. Watts. Knowns and unknowns in the care of pediatric familial hypercholesterolemia

Normal pregnancy requires adaptations of the maternal vasculature. During preeclampsia these adaptations are not well established, which may be related to maternal hypertension and proteinuria. The effects of preeclampsia on the maternal vasculature are not yet fully understood. We aimed to evaluate gene expression in aortas of pregnant rats with experimental preeclampsia using a genome wide microarray. Aortas were isolated from pregnant Wistar outbred rats with low-dose LPS-induced preeclampsia (ExpPE), healthy pregnant (Pr), non-pregnant and low-dose LPS-infused non-pregnant rats. Gene expression was measured by microarray and validated by real-time quantitative PCR. Gene Set Enrichment Analysis was performed to compare the groups. Functional analysis of the aorta was done by isotonic contraction measurements while stimulating aortic rings with potassium chloride. 526 genes were differentially expressed, and positive enrichment of “potassium channels”, “striated muscle contraction”, and “neuronal system” gene sets were found in ExpPE vs. Pr. The potassium chloride-induced contractile response of ExpPE aortic rings was significantly decreased compared to this response in Pr animals. Our data suggest that potassium channels, neuronal system and (striated) muscle contraction in the aorta may play a role in the pathophysiology of experimental preeclampsia. Whether these changes are also present in preeclamptic women needs further investigation.

Microbleeds, small perivascular collections of hemosiderin manifested radiologically as hypointensities on gradient-echo magnetic resonance imaging (MRI), are important markers of small vessel pathology. Despite their clinical relevance, little is known about their prevalence and demographic correlates, particularly among ethnically diverse older adults. We examined demographic and clinical correlates of regional microbleeds in a multi-ethnic cohort and examined categorization schemes of microbleed distribution and severity.Between 2005 and 2007, 769 individuals participated in a MRI study as part of the Washington Heights/Inwood Columbia Aging Project. Approximately four years later, 243 out of 339 participants (mean age=84.50) who returned for a repeat MRI had gradient-echo scans for microbleed assessment and comprised the sample. We examined the association of deep and lobar microbleeds with age, sex, education, vascular factors, cognitive status and markers of small vessel disease.Sixty-seven of the 243 (27%) participants had at least one microbleed. Individuals with microbleeds were more likely to have a history of stroke than individuals without. When categorized as having either no microbleeds, microbleeds in deep regions only, in lobar regions only, and both deep and lobar microbleeds, hypertension, proportion of strokes, and white matter hyperintensity volume (WMH) increased monotonically across the four groups. The number of lobar microbleeds correlated with WMH volume and diastolic blood pressure.Microbleeds in deep and lobar locations are associated with worse outcomes than microbleeds in either location alone, although the presence of lobar microbleeds appears to be more clinically relevant.

PURPOSE: To determine the impact of late radiation-induced toxicity on health-related quality of life (HRQoL) among patients with prostate cancer.PATIENTS AND METHODS: The study sample was composed of 227 patients, treated with external beam radiotherapy. Common Terminology Criteria for Adverse Events version 3.0 were used to grade late genitourinary and gastrointestinal toxicity. The European Organization for Research and Treatment of Cancer Quality of life Questionnaire C30 (EORTC QLQ-C30) was used to assess HRQoL at baseline, and 6, 12 and 24 months after completion of radiotherapy. Statistical analysis was performed using a multivariate analysis of variance (MANOVA).RESULTS: Urinary incontinence and rectal discomfort significantly affected HRQoL. The impact of urinary incontinence on HRQoL was most pronounced 6 months after radiotherapy and gradually decreased over time. The impact of rectal discomfort on HRQoL was predominant at 6 months after radiotherapy, decreased at 12 months and increased again 2 years after radiotherapy. No significant impact on HRQoL was observed for any of the other toxicity endpoints, or non-toxicity related factors such as hormonal therapy, radiotherapy technique or age.CONCLUSION: Urinary incontinence and rectal discomfort have a significant impact on HRQoL. Prevention of these side effects may likely improve quality of life of prostate cancer patients after completion of treatment.

Cardiovascular disease (CVD) remains the leading cause of death and morbidity in our society. One of the major risk factors for CVD is hypercholesterolemia. Hypercholesterolemia in children can be caused by a hereditary disorder or can be secondary to other diseases or drugs. In order to prevent CVD later in life, children with hypercholesterolemia should be identified and treated as early as possible. Currently, several different screening strategies have been developed, using either universal screening or case finding to search for children at risk. Once those children are identified, the first step in treatment is lifestyle adjustment. If cholesterol levels remain elevated, the drugs of first choice are statins. Other pharmacological options are ezetimibe or bile acid sequestrants. These agents have all proven to be safe and effective in lowering low-density lipoprotein cholesterol levels and improving surrogate markers of CVD. However, there is a need for long-term follow-up studies to answer the question as to whether it is safe to initiate treatment at a young age to prevent CVD later in life.

Familial hypercholesterolaemia (FH) is a dominantly inherited disorder present from birth that markedly elevates plasma low-density lipoprotein (LDL) cholesterol and causes premature coronary heart disease. There are at least 20 million people with FH worldwide, but the majority remains undetected and current treatment is often suboptimal. To address this major gap in coronary prevention we present, from an international perspective, consensus- based guidance on the care of FH. The guidance was generated from seminars and workshops held at an international symposium. The recommendations focus on the detection, diagnosis, assessment and management of FH in adults and children, and set guidelines for clinical purposes. They also refer to best practice for cascade screening and risk notifying and testing families for FH, including use of genetic testing. Guidance on treatment is based on risk stratification, management of noncholesterol risk factors and safe and effective use of LDL lowering therapies. Recommendations are given on lipoprotein apheresis. The use of emerging therapies for FH is also foreshadowed. This international guidance acknowledges evidence gaps, but aims to make the best use of contemporary practice and technology to achieve the best outcomes for the care of FH. It should accordingly be employed to inform clinical judgment and be adjusted for country-specific and local healthcare needs and resources.
