Low-density lipoprotein (LDL)-cholesterol (LDL-c) and lipoprotein(a) [Lp(a)] are independent cardiovascular risk factors. Reduction of LDL-c leads to reduction in cardiovascular events, regardless of the method of reducing LDL-c levels. Lifestyle modification and drugs are first line treatment options. However, many patients do not reach treatment goals, as defined in guidelines worldwide, through standard medication. So far, drugs are not efficient in lowering Lp(a) levels, or the reduction of plasma levels does not result in clinical benefit. In these two groups of patients lipoprotein apheresis is very efficient in decreasing LDL-c and Lp(a) levels. A single apheresis session can decrease LDL-c and Lp(a) by approximately 65%, and apheresis performed weekly or biweekly results in considerably decreased mean interval concentrations (approximately 30% reduction). Most apheresis systems (HELP, heparin induced extracorporeal LDL precipitation; DALI, direct adsorption of lipoproteins; lipoprotein apheresis with dextran sulfate; lipid filtration; immunoadsorption) decrease LDL-c and Lp(a). Lipopac is a specific form of immunapheresis and only decreases Lp(a). Lipoprotein apheresis is a well-tolerated treatment option but it is expensive and time consuming. The evidence for clinical benefit through regular apheresis comes from observational data. Adequate, randomised, controlled trials are lacking., (Copyright © 2019 Royal College of Pathologists of Australasia. Published by Elsevier B.V. All rights reserved.)

Background: Lipoprotein apheresis effectively lowers lipoprotein(a) [Lp(a)] and low-density lipoprotein (LDL) by approximately 60%-70%. The rebound of LDL and Lp(a) particle concentrations following lipoprotein apheresis allows the determination of fractional catabolic rate (FCR) and hence production rate (PR) during non-steady state conditions. We aimed to investigate the kinetics of Lp(a) and LDL apolipoprotein B-100 (apoB) particles in patients with elevated Lp(a) and coronary artery disease undergoing regular apheresis., Patients and Methods: A cross-sectional study was carried out in 13 patients with elevated Lp(a) concentration (>500 mg/L) and coronary artery disease. Lp(a) and LDL-apoB metabolic parameters, including FCR and PR were derived by the fit of a compartment model to the Lp(a) and LDL-apoB concentration data following lipoprotein apheresis., Results: The FCR of Lp(a) was significantly lower than that of LDL-apoB (0.39 [0.31, 0.49] vs 0.57 [0.46, 0.71] pools/day, P = 0.03) with no significant differences in the corresponding PR (14.80 [11.34, 19.32] vs 15.73 [11.93, 20.75] mg/kg/day, P = 0.80). No significant associations were observed between the FCR and PR of Lp(a) and LDL-apoB., Conclusions: In patients with elevated Lp(a), the fractional catabolism of Lp(a) is slower than that of LDL-apoB particles, implying that different metabolic pathways are involved in the catabolism of these lipoproteins. These findings have implications for new therapies for lowering apolipoprotein(a) and apoB to prevent atherosclerotic cardiovascular disease., (© 2018 Stichting European Society for Clinical Investigation Journal Foundation.)

Background and Aims: It is unknown whether a school-based prevention program has the potential to improve microvascular health in children. This study investigates the impact of the school-based lifestyle intervention program JuvenTUM 3 on physical activity, physical fitness, serum biomarkers and microvascular function., Methods: We studied 434 children (10-11 years) in a cluster-randomized setting (8 intervention schools, IG; 7 control schools, CG) over 18 months. The school-based prevention program included weekly lifestyle lessons for children with the aim to increase physical activity in and outside of school, physical fitness as well as health behavior. Anthropometric measurements and blood sampling were conducted using standard protocols, physical activity by use of a questionnaire and physical fitness by a 6-item-test battery. Central retinal arteriolar (CRAE) and venular (CRVE) vessel diameters as early marker of vascular dysfunction, as well as the arteriolar-to-venular diameter ratio (AVR), were investigated with a non-mydriatic vessel analyser., Results: School-based physical activity increased in 41% of children in IG (19% in CG, p = 0.038). Improvements in vascular parameters were observed for AVR (increase in 83% of children in IG versus 50% in CG; p < 0.001) and for CRVE (43% of children with retinal venular widening in IG versus 58% in CG, p = 0.019). These vascular improvements were also seen in overweight children for CRAE (p = 0.021) and AVR (p < 0.001)., Conclusions: The school-based prevention program JuvenTUM 3 increased physical activity at school inducing favourable effects on retinal microvasculature function. These findings underline the importance of early lifestyle interventions in children for primary prevention of cardiovascular disease., (Copyright © 2018 Elsevier B.V. All rights reserved.)

Background and Aims: Familial hypercholesterolemia (FH) is amongst the most common genetic disorders encountered in primary care. Yet, only a minority of affected patients is diagnosed and treated. This interim analysis of the CaRe High Registry aims at examining the state of treatment and attainment of lipid goals in German FH patients., Methods: The CaRe High registry includes FH patients from lipid clinics and private practices. Data have been collected using questionnaires filled in by the recruiting physicians and by interviewing the participating patients., Results: We examined 512 F H patients diagnosed according to clinical criteria. Median age at the time of the first FH diagnosis was 39 (25th and 75th percentile: 27-50) years, median treatment naïve LDL cholesterol (LDL-C) was 239.4 mg/dl (6.19 mmol/l), 25th to 75th percentile 191.8-342.5 mg/dl (4.96-8.86 mmol/l). 27% of the participants did not receive lipid-lowering drugs. Among the patients treated with lipid-lowering drugs, 19% received a PCSK9 inhibitor (PCSK9i) in combination with a statin, 9% were treated with a PCSK9i alone and 3% were treated with a combination of PCSK9i and a non-statin drug. Patients with pre-existing CVD were more likely to be treated with lipid-lowering drugs and more likely to receive a PCSK9i, but LDL-C targets were only achieved by a minority of patients (<20%). Gap to target LDL-C was lowest and the median achieved LDL-C reduction was 1.4 times higher with PCSK9i treatment than with (oral) lipid-lowering therapy without PCSK9i., Conclusions: The Care High registry has included patients with the typical clinical features of familial hypercholesterolemia. PCSK9i treatment in addition to standard therapy allows attainment of target values in many patients with initially very high LDL-C., (Copyright © 2018 The Authors. Published by Elsevier B.V.

Background: The obesity epidemic has continued to spread across the globe involving even poor nations of the world., Method: Household population survey of adults aged 20-60 years. Multistage stratified cluster randomised sampling involving both urban and rural statewide representative population samples. Anthropometric measurements were taken using standard methods. Prevalences were weighted and multinomial regression analyses were done., Results: A total of 6628 individuals from 2843 households were surveyed. The weighted overall prevalence for underweight was 9.1% (95% CI 8.1 to 10.1), 65.1% (95% CI 63.6 to 66.6) for normal weight, 19.0% (95% CI 17.8 to 20.3) for overweight and 6.8% (95% CI 6.0 to 7.5) for obese. Men were less likely to be overweight (adjusted OR (AOR) 0.79; 95% CI 0.68 to 0.92) and obese (AOR 0.24; 95% CI 0.19 to 0.31) than women. Urban residents were more likely to be overweight (AOR 1.42; 95% CI 1.18 to 1.71) and obese (AOR 2.09; 95% CI 1.58 to 2.76) than rural residents. Each additional 1-year increase in age increased the risk of overweight by 1.012 (AOR 1.012; 95% CI 1.005 to 1.018) and that of obesity by 1.03 (AOR 1.03; 95% CI 1.02 to 1.04). The low-income class was less likely to be overweight (AOR 0.694; 95% CI 0.507 to 0.951) and obese (AOR 0.44; 95% CI 0.28 to 0.67)., Conclusion: The prevalence of obesity and overweight in Enugu Nigeria is high and fast approaching that of underweight. Women, urban dwellers, older adults and high-income earners are at higher risk for obesity and overweight. The study provides robust information for public health policies towards the prevention of obesity in Nigeria., Competing Interests: Competing interests: None declared., (© Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Regular walnut consumption is associated with better health. We have previously shown that eight weeks of walnut consumption (43 g/day) significantly improves lipids in healthy subjects. In the same study, gut microbiome was evaluated. We included 194 healthy subjects (134 females, 63 ± 7 years, BMI 25.1 ± 4.0 kg/m²) in a randomized, controlled, prospective, cross-over study. Following a nut-free run-in period, subjects were randomized to two diet phases (eight weeks each); 96 subjects first followed a walnut-enriched diet (43 g/day) and then switched to a nut-free diet, while 98 subjects followed the diets in reverse order. While consuming the walnut-enriched diet, subjects were advised to either reduce fat or carbohydrates or both to account for the additional calories. Fecal samples were collected from 135 subjects at the end of the walnut-diet and the control-diet period for microbiome analyses. The 16S rRNA gene sequencing data was clustered with a 97% similarity into Operational Taxonomic Units (OTUs). UniFrac distances were used to determine diversity between groups. Differential abundance was evaluated using the Kruskal-Wallis rank sum test. All analyses were performed using Rhea. Generalized UniFrac distance shows that walnut consumption significantly affects microbiome composition and diversity. Multidimensional scaling (metric and non-metric) indicates dissimilarities of approximately 5% between walnut and control ( p = 0.02). The abundance of Ruminococcaceae and Bifidobacteria increased significantly ( p < 0.02) while Clostridium sp. cluster XIVa species ( Blautia ; Anaerostipes ) decreased significantly ( p < 0.05) during walnut consumption. The effect of walnut consumption on the microbiome only marginally depended on whether subjects replaced fat, carbohydrates or both while on walnuts. Daily intake of 43 g walnuts over eight weeks significantly affects the gut microbiome by enhancing probiotic- and butyric acid-producing species in healthy individuals. Further evaluation is required to establish whether these changes are preserved during longer walnut consumption and how these are linked to the observed changes in lipid metabolism., Competing Interests: C.B., A.R., K.L., L.W., E.W., S.F., J.A. and K.H. have nothing to disclose. The research was supported by a grant from the California Walnut Commission (Folsom, CA, USA) to KGP. The Walnut Commission had no role in study performance, data analysis and or manuscript writing.

Objective: PANORAMA, a nine-country cross-sectional type 2 diabetes study, investigated factors associated with quality of life (QoL), health status, and other patient-reported outcome measures (PROMs)., Research Design and Methods: Patients were randomly or consecutively selected from primary/secondary care. PROMs included the Audit of Diabetes-Dependent Quality of Life (ADDQoL) (generic QoL item and average weighted impact [AWI] scores), Diabetes Treatment Satisfaction Questionnaire (DTSQ) (patient- and physician-completed), Hypoglycemia Fear Survey-II worry subscale, and the EuroQoL-5 Dimension visual analog scale (EQ-VAS) measuring patient-reported health. Multivariable linear regression analyses determined predictors of each PROM including patient characteristics, physician-reported adherence, complications, and glycosylated hemoglobin., Results: In 5,813 patients, mean PROM scores indicated that generic QoL approximated "good" (0.93); perceived impact of diabetes on QoL was negative (AWI -1.69). Treatment satisfaction exceeded physicians' estimates (patient-reported: 29.76; physician-estimated: 27.75), but so did patients' perceived frequency of hypo-/hyperglycemia. Worry about hypoglycemia (13.27) was apparent. Intensifying treatments to three oral agents or insulin regimens predicted worse QoL (AWI P < 0.01). Insulin alone use predicted worse QoL (generic P < 0.02; AWI P < 0.001) and hypoglycemia worry ( P < 0.007). No treatment had significant associations with EQ-VAS health status., Conclusions: Predictors for different PROMs differed markedly and provided insights for understanding and improving these important outcomes. Intensive treatment regimens had significant negative associations with all PROMs, except the EQ-VAS health status measure. The findings demonstrate the importance of measuring QoL alongside health status and other patient-reported outcomes when evaluating diabetes treatments with a view to protecting QoL and facilitating adherence and long-term glycemic control., (© 2017 by the American Diabetes Association.)

Patients with diabetes mellitus have an elevated cardiovascular risk. Lipid-lowering therapy is a successful strategy to prevent atherosclerotic events in these patients. Therefore, almost all professional societies recommend statin therapy for patients with diabetes under certain conditions. Despite this broad consensus, a number of controversial issues remain. Thus, it remains unclear in which patients the lipid parameters should be determined in the fasting state and in which postprandial values are sufficient. It is also an open issue whether all patients with diabetes should receive statin therapy and which goals should be achieved. While the benefit of statin-ezetimibe and statin-PCSK9-inhibition combinations has been shown in large outcome trials, results of outcome trials involving statins with triglyceride lowering drugs have been ambiguous. Thus, it is currently unclear which patients benefit from such combinations. Finally, the best strategy to address severe hypertriglyceridemia in patients with diabetes is unclear. This article discusses these issues and aims to provide help and information to practicing physicians taking care of patients with diabetes mellitus.

Purpose of Review: Although lipid-lowering treatment with statins, ezetimibe, and PCSK9 inhibitors is a very successful strategy to prevent cardiovascular events, there is a need for further drug developments. Not all patients respond sufficiently to the available therapy (very high baseline values, intolerance). Furthermore, patients may be characterized by dyslipidemias not accessible to available drugs such as patients with homozygous familial hypercholesterolemia, chylomicronemia syndrome, or elevated lipoprotein(a). A number of drugs are being developed to close these gaps., Recent Findings: The focus is on new antibodies, antisense oligonucleotides, and small molecules that address different aspects of lipid metabolism. Many of these developments are promising as they decrease LDL-cholesterol and/or non-HDL-cholesterol and/or triglycerides and/or lipoprotein(a) in patients who so far cannot be treated sufficiently. These drugs are currently in different stages of development and being tested in clinical trials., Summary: Some of the new lipid-lowering drugs have a very promising profile. However, eventually phase 3 and outcome trials will be required to prove the usefulness of these compounds in clinical practice. Furthermore, it is unlikely that they will change the primary lipidological approach (statin and ezetimibe) even if they prove successful.

Studies indicate a positive association between walnut intake and improvements in plasma lipids. We evaluated the effect of an isocaloric replacement of macronutrients with walnuts and the time point of consumption on plasma lipids. We included 194 healthy subjects (134 females, age 63 ± 7 years, BMI 25.1 ± 4.0 kg/m²) in a randomized, controlled, prospective, cross-over study. Following a nut-free run-in period, subjects were randomized to two diet phases (8 weeks each). Ninety-six subjects first followed a walnut-enriched diet (43 g walnuts/day) and then switched to a nut-free diet. Ninety-eight subjects followed the diets in reverse order. Subjects were also randomized to either reduce carbohydrates ( n = 62), fat ( n = 65), or both ( n = 67) during the walnut diet, and instructed to consume walnuts either as a meal or as a snack. The walnut diet resulted in a significant reduction in fasting cholesterol (walnut vs., Control: -8.5 ± 37.2 vs. -1.1 ± 35.4 mg/dL; p = 0.002), non-HDL cholesterol (-10.3 ± 35.5 vs. -1.4 ± 33.1 mg/dL; p ≤ 0.001), LDL-cholesterol (-7.4 ± 32.4 vs. -1.7 ± 29.7 mg/dL; p = 0.029), triglycerides (-5.0 ± 47.5 vs. 3.7 ± 48.5 mg/dL; p = 0.015) and apoB (-6.7 ± 22.4 vs. -0.5 ± 37.7; p ≤ 0.001), while HDL-cholesterol and lipoprotein (a) did not change significantly. Neither macronutrient replacement nor time point of consumption significantly affected the effect of walnuts on lipids. Thus, 43 g walnuts/d improved the lipid profile independent of the recommended macronutrient replacement and the time point of consumption., Competing Interests: C.B., A.R., K.L., L.W., E.W., R.S., J.A. and K.H. declare no conflict of interest. The research was supported by a grant from the California Walnut Commission (Folsom, CA) to K.G.P.. The Walnut Commission had no role in study performance, data analysis and or manuscript writing.

Background: While several lines of evidence prove that elevated concentrations of low-density lipoproteins (LDL) causally contribute to the development of atherosclerosis and its clinical consequences, high-density lipoproteins are still widely believed to exert atheroprotective effects. Hence, HDL cholesterol (HDL-C) is in general still considered as "good cholesterol". Recent research, however, suggests that this might not always be the case and that a fundamental reassessment of the clinical significance of HDL-C is warranted., Method: This review article is based on a selective literature review., Results: In individuals without a history of cardiovascular events, low concentrations of HDL-C are inversely associated with the risk of future cardiovascular events. This relationship may, however, not apply to patients with metabolic disorders or manifest cardiovascular disease. The classical function of HDL is to mobilise cholesterol from extrahepatic tissues for delivery to the liver for excretion. These roles in cholesterol metabolism as well as many other biological functions of HDL particles are dependent on the number as well as protein and lipid composition of HDL particles. They are poorly reflected by the HDL-C concentration. HDL can even exert negative vascular effects, if its composition is pathologically altered. High serum HDL-C is therefore no longer regarded protective. In line with this, recent pharmacological approaches to raise HDL-C concentration have not been able to show reductions of cardiovascular outcomes., Conclusion: In contrast to LDL cholesterol (LDL-C), HDL-C correlates with cardiovascular risk only in healthy individuals. The calculation of the ratio of LDL-C to HDL-C is not useful for all patients. Low HDL-C should prompt examination of additional metabolic and inflammatory pathologies. An increase in HDL-C through lifestyle change (smoking cessation, physical exercise) has positive effects and is recommended. However, HDL-C is currently not a valid target for drug therapy.

Background: In sub-Saharan Africa the prognosis of children with type 1 diabetes is poor. Many are not diagnosed and those diagnosed have a dramatically reduced life expectancy (less than one year). The purpose of this study was to identify the predictors of glucose control in children and adolescents with type 1 diabetes., Methods: This hospital based cross-sectional study involved 76 children/adolescents (35 boys and 41 girls, mean age of 15.1 ± 3.1 years) with type 1 diabetes included in the "Changing Diabetes in Children" (CDiC) program and attending the clinics for children living with type 1 diabetes in the North West Region of Cameroon. Data on glycosylated haemoglobin (HbA1c) was obtained from hospital records of participants. Information on socio-demographic characteristics and diabetes related practices were obtained from participants using a structured questionnaire. Odds ratios (OR) were calculated using logistic regression models to assess the association between determinants and good glyceamic control., Results: The study population had a mean HbA1c of 10.3 ± 2.9%. Bivariate analysis indicated that having a mother as the primary caregiver (OR 0.07, 95% CI 0.02-0.2), being on 2 daily insulin injections (OR 0.2, 95% CI 0.1-0.5) and good blood glucose monitoring (BGM) adherence (OR 0.1, 95% CI 0.04-0.3) were significantly (p < 0.001) associated with better HbA1c. Minimal/moderate caregiver involvement in BGM (OR 7.7, 95% CI 2.7-22.0) and insulin injection (OR 14.9, 95% CI 4.8-46.5) were significantly (p < 0.001) associated with poor outcome. Multivariate analysis showed that having a mother as the primary caregiver (OR 0.02, 95% CI 0.002-0.189) was an independent predictor of good glucose control., Conclusions: This study has shown that the mother's involvement in the diabetes management of their children and minimal/moderate caregiver involvement in the task of insulin injection are the most important determinants for good and poor glucose control respectively. It is currently unclear whether the direct involvement of the mother is causal or whether "mother as a primary caregiver" is just an indicator for a setting in which good diabetes treatment is possible.

Introduction: Hypercholesterolemia is a causal risk factor for cardiovascular diseases, which is recommended to be treated at least in high-risk patients. Yet, currently there is a lack of epidemiological data on the number of high-risk patients in Germany who do not respond adequately to high-dose statin monotherapy or statin therapy in combination with other lipid-lowering agents., Methods: Of a total of over 2.6 million patient records from general practitioners in the IMS Disease Analyzer database, all high-risk cardiovascular patients with hypercholesterolemia who did not reach target low-density lipoprotein-cholesterol (LDL-C) levels despite at least 12 months of maximum lipid-lowering therapy and optimal medication supply (medication possession rate≥80%) were selected over a defined period., Results: On the basis of the practice data, a total of 602 133 patients with a high cardiovascular risk who were treated with statin monotherapy or statin combination therapy with optimal medication supply (medication possession rate≥80%) for at least 12 months were identified. Of them, 49 406 patients received high-dose statin therapy, and 51 869 patients received statin therapy in any dose in combination with another lipid-lowering agent. A total of 79 848 high-risk patients did not reach the target LDL-C level of 70 mg/dl or less despite consistent lipid-lowering therapy; of them, 12 808 had a documented LDL-C level of at least 130 mg/dl., Conclusion: The prevalence of high-risk cardiovascular patients with therapy-resistant hypercholesterolemia is substantial in Germany.

Following the continuous accumulation of evidence supporting the beneficial role of reducing low-density lipoprotein cholesterol (LDL-C) levels in the treatment and prevention of atherosclerotic cardiovascular disease and its complications, therapeutic possibilities now exist to lower LDL-C to very low levels, similar to or even lower than those seen in newborns and nonhuman species. In addition to the important task of evaluating potential side effects of such treatments, the question arises whether extremely low LDL-C levels per se may provoke adverse effects in humans. In this review, we summarize information from studies of human cellular and organ physiology, phenotypic characterization of rare genetic diseases of lipid metabolism, and experience from clinical trials. Specifically, we emphasize the importance of the robustness of the regulatory systems that maintain balanced fluxes and levels of cholesterol at both cellular and organismal levels. Even at extremely low LDL-C levels, critical capacities of steroid hormone and bile acid production are preserved, and the presence of a cholesterol blood-brain barrier protects cells in the central nervous system. Apparent relationships sometimes reported between less pronounced low LDL-C levels and disease states such as cancer, depression, infectious disease and others can generally be explained as secondary phenomena. Drug-related side effects including an increased propensity for development of type 2 diabetes occur during statin treatment, whilst further evaluation of more potent LDL-lowering treatments such as PCSK9 inhibitors is needed. Experience from the recently reported and ongoing large event-driven trials are of great interest, and further evaluation including careful analysis of cognitive functions will be important., (© 2017 The Association for the Publication of the Journal of Internal Medicine.)

Although hyperlipidemia is common in COPD, its relationship to comorbidities, risk factors and lung function in COPD has not been studied in detail. Using the baseline data of the COSYCONET cohort we addressed this question. Data from 1746 COPD patients (GOLD stage 1-4; mean age 64.6 y, mean FEV1%pred 57%) were evaluated, focusing on the comorbidities hyperlipidemia, diabetes and cardiovascular complex (CVC; including arterial hypertension, cardiac failure, ischemic heart disease). Risk factors comprised age, gender, BMI, and packyears of smoking. The results of linear and logistic regression analyses were implemented into a path analysis model describing the multiple relationships between parameters. Hyperlipidemia (prevalence 42.9%) was associated with lower intrathoracic gas volume (ITGV) and higher forced expiratory volume in 1 second (FEV1) when adjusting for its multiple relationships to risk factors and other comorbidities. These findings were robust in various statistical analyses. The associations between comorbidities and risk factors were in accordance with previous findings, thereby underlining the validity of our data. In conclusion, hyperlipidemia was associated with less hyperinflation and airway obstruction in patients with COPD. This surprising result might be due to different COPD phenotypes in these patients or related to effects of medication.

Background and Aims: In this study, we evaluated the effect of mipomersen in patients with severe LDL-hypercholesterolaemia and atherosclerosis, treated by lipid lowering drugs and regular lipoprotein apheresis., Methods: This prospective, randomized, controlled phase II single center trial enrolled 15 patients (9 males, 6 females; 59 ± 9 y, BMI 27 ± 4 kg/m 2 ) with established atherosclerosis, LDL-cholesterol ≥130 mg/dL (3.4 mmol/L) despite maximal possible drug therapy, and fulfilling German criteria for regular lipoprotein apheresis. All patients were on stable lipid lowering drug therapy and regular apheresis for >3 months. Patients randomized to treatment (n = 11) self-injected mipomersen 200 mg sc weekly, at day 4 after apheresis, for 26 weeks. Patients randomized to control (n = 4) continued apheresis without injection. The primary endpoint was the change in pre-apheresis LDL-cholesterol., Results: Of the patients randomized to mipomersen, 3 discontinued the drug early (<12 weeks therapy) for side effects. For these, another 3 were recruited and randomized. Further, 4 patients discontinued mipomersen between 12 and 26 weeks for side effects (moderate to severe injection site reactions n = 3 and elevated liver enzymes n = 1). In those treated for >12 weeks, mipomersen reduced pre-apheresis LDL-cholesterol significantly by 22.6 ± 17.0%, from a baseline of 4.8 ± 1.2 mmol/L to 3.7 ± 0.9 mmol/L, while there was no significant change in the control group (+1.6 ± 9.3%), with the difference between the groups being significant (p=0.006). Mipomersen also decreased pre-apheresis lipoprotein(a) (Lp(a)) concentration from a median baseline of 40.2mg/dL (32.5,71) by 15% (-19.4,3.6) though without significance (p=0.3)., Conclusions: Mipomersen reduces LDL-cholesterol (significantly) and Lp(a) (non-significantly) in patients on maximal lipid-lowering drug therapy and regular apheresis, but is often associated with side effects., (Copyright © 2017 Elsevier B.V.

Background  Hypercholesterolemia plays a causal role in the development of cardiovascular diseases. Patients are affected differently. There is a lack of epidemiological data about the frequence and characteristics of patients in Germany, especially about those who do not respond sufficiently to high intensity statins with or without other lipid modifying therapies. Methods  From more than 2.6 million patient records of office based general practitioners, patients with hypercholestrolemia and high cardiovascular risk, who do not reach their individual LDL-C goal despite a best supplied twelve month maximum lipid lowering therapy (MPR ≥ 80 %), were extracted from the database. Results  5791 909 statutorily insured German patients are extrapolated with hypercholesterolemia (95 % CI: 5787 368 - 5796 454). 602 133 (95 % CI: 600 620 - 603 650) patients with high cardiovascular risk were treated with high intensity lipid modifying therapy (medication possession rate ≥ 80 %) for at least 1 year. 49 406 (95 % CI: 48 972 - 49 843) of them got mono-therapy with high intensity statins, 51 869 (95 % CI: 51 425 - 52 317) received statins in any dose combined with other lipid lowering drugs. 79 848 (95 % CI: 79 313 - 80 385) high risk patients did not reach LDL-C < 70 mg/dl despite optimal lipid treatment. 12 808 (95 % CI: 12 589 - 13 030) high risk patients even had LDL-C values ≥ 130 mg/dl. Discussion  To classify patient's therapy refractory, they must have maximal drug therapy over a sufficient period of time. Usually statins are prescribed as first line therapy. Due to adverse events or contraindications statins are often prescribed in submaximal doses. Therefore patients with statins at lower dose combined with another lipid lowering drug were also included in the analysis. For patients missing the LDL-C target of ≤ 130 mg/dl despite optimal lipid lowering therapy there is a high medical need for innovative therapies., (© Georg Thieme Verlag KG Stuttgart · New York.)

Backround: Each year 16-17 million determinations of high-density lipoprotein cholesterol (HDL-C) are conducted and interpreted in Germany. Recently acquired data have led to a fundamental reassessment of the clinical significance of HDL-C., Method: This review article is based on a selective literature search., Results: Low HDL‑C levels usually indicate an increased cardiovascular risk, particularly in primary prevention but the epidemiological relationship between HDL‑C and the risk is complex. The HDL plays a role in the back transport and excretion of cholesterol; however, the biological functions of HDL are dependent on the protein and lipid composition, which is not reflected by the HDL‑C concentration. If the composition of HDL is pathologically altered it can also exert negative vascular effects., Conclusion: Compared with low-density lipoprotein cholesterol (LDL-C), HDL‑C is of secondary importance for cardiovascular risk stratification and the calculation of the LDL-C:HDL‑C ratio is not useful for all patients. Low HDL‑C levels should prompt a search for additional metabolic and inflammatory pathologies. An increase in HDL‑C through lifestyle changes (e.g. smoking cessation and physical exercise) has positive effects and is recommended; however, HDL‑C is currently not a valid target for drug therapy.

Background: Familial chylomicronemia syndrome (FCS) is a rare genetic disease that leads to severe hypertriglyceridemia often associated with recurrent episodes of pancreatitis. The recognition and correct diagnosis of the disease is challenging due to its rarity, and to the lack of specificity of signs and symptoms. Lipid experts, endocrinologists, gastroenterologists, pancreatologists, and general practitioners may encounter patients who potentially have FCS. Therefore, cooperation between experts and improved knowledge of FCS is essential in improving the diagnosis. Currently, a consensus on best practice for the diagnosis of FCS is lacking., Methods: Aiming to define a diagnostic algorithm for FCS, a board of European experts was instituted. Such an algorithm for FCS is important to guide practitioners in the diagnosis of suspected FCS and to optimize therapeutic strategies., Results: The multidisciplinary views were merged, leading to a diagnostic algorithm, proposed here., Conclusion: This diagnostic algorithm represents a potentially useful tool to support primary and secondary care practitioners in the recognition of signs and clinical manifestations in individuals potentially affected by FCS., (Copyright © 2016 Elsevier Ireland Ltd.

Aim: To evaluate the effect of alirocumab on frequency of standard apheresis treatments [weekly or every 2 weeks (Q2W)] in heterozygous familial hypercholesterolaemia (HeFH)., Methods and Results: ODYSSEY ESCAPE (NCT02326220) was a double-blind study in 62 HeFH patients undergoing regular weekly or Q2W lipoprotein apheresis. Patients were randomly assigned (2:1, respectively) to receive alirocumab 150 mg (n = 41) or placebo (n = 21) Q2W subcutaneously for 18 weeks. From day 1 to week 6, apheresis rate was fixed according to the patient's established schedule; from weeks 7 to 18, apheresis rate was adjusted based on the patient's low-density lipoprotein cholesterol (LDL-C) response in a blinded fashion. Apheresis was not performed when the LDL-C value was ≥30% lower than the baseline (pre-apheresis) value. The primary efficacy endpoint was the rate of apheresis treatments over 12 weeks (weeks 7-18), standardized to number of planned treatments. In the alirocumab group the least square (LS) mean ± SE (95% confidence interval [CI]) per cent change in pre-apheresis LDL-C from baseline at week 6 was -53.7 ± 2.3 (-58.2 to - 49.2) compared with 1.6 ± 3.1 (-4.7 to 7.9) in the placebo group. The primary efficacy endpoint showed statistically significant benefit in favour of alirocumab (Hodges-Lehmann median estimate of treatment difference: 0.75; 95% CI 0.67-0.83; P < 0.0001). Therefore, alirocumab-treated patients had a 0.75 (75%) additional reduction in the standardized rate of apheresis treatments vs. placebo-treated patients. During this period, 63.4% of patients on alirocumab avoided all and 92.7% avoided at least half of the apheresis treatments. Adverse event rates were similar (75.6% of patients on alirocumab vs. 76.2% on placebo)., Conclusions: Lipoprotein apheresis was discontinued in 63.4% of patients on alirocumab who were previously undergoing regular apheresis, and the rate was at least halved in 92.7% of patients. Alirocumab was generally safe and well tolerated., (© The Author 2016. Published by Oxford University Press on behalf of the European Society of Cardiology.)

An elevated plasma concentration of lipoprotein (a) [Lp(a)] is an independent risk factor for cardiovascular disease. Life style modification and currently available drugs either fail to effectively lower plasma Lp(a) levels or do not result in clinical benefit. However, lipoprotein apheresis is very efficient in decreasing Lp(a) concentrations. A single apheresis session can acutely decrease Lp(a) by approximately 60-75%, and apheresis performed weekly or biweekly results in considerably decreased mean interval concentrations (approximately 25-40% reduction). While most apheresis systems (heparin-induced extracorporeal LDL precipitation, direct adsorption of lipoproteins, lipoprotein apheresis with dextran-sulfate, lipid filtration, immunoadsorption) decrease LDL and Lp(a), Lipopac is specific and only decreases Lp(a). Lp(a) apheresis is expensive and time consuming, but associated with very few side effects. Two randomized controlled trials give conflicting consults with respect to the effect on angiographic changes. Retrospective analyses indicate that regular apheresis translates into clinical benefit in patients with elevated Lp(a), but adequate randomized controlled trials are lacking., (Copyright © 2016 by the American Society for Biochemistry and Molecular Biology, Inc.)

Objective: Familial hypobetalipoproteinemia (FHBL) is characterized by mutations in APOB, the majority of these causing protein truncations, and low plasma levels of apolipoprotein (apo) B. The hypobetalipoproteinemia may be due to enhanced clearance and possibly reduced production of apoB-containing lipoproteins; the mechanism may depend on the length of the apoB truncation. We studied fasting lipoprotein metabolism in an FHBL subject heterozygous for a mutation causing a truncated apoB, apoB-80., Design and Methods: Very low density lipoprotein (VLDL)-, intermediate density lipoprotein (IDL)-, and low density lipoprotein (LDL)-apoB kinetics were determined in the fasting state using stable isotope methods and compartmental modeling., Results: Compared with lean normolipidemic controls the apoB-80 FHBL subject had an elevated VLDL-apoB fractional catabolic rate and lower LDL production. ApoB production rates and IDL- and LDL-apoB fractional catabolic rates were not different., Conclusion: FHBL subjects heterozygous for a mutation truncating apoB to 80% of full-length are able to produce VLDL-apoB normally, but have rapid clearance of these particles, resulting in low levels of circulating apoB., (Copyright © 2016 The Canadian Society of Clinical Chemists.

The interrelation between glucose and lipid metabolism is complex and comprises many aspects. In this context diabetic dyslipidemia is of utmost importance as it represents the crucial link between diabetes and cardiovascular disease. Although hypertriglyceridemia is usually the most prominent lipid abnormality in diabetic patients, reduction of low-density lipoprotein (LDL) cholesterol is the most important strategy to prevent cardiovascular disease. Statin trials and more recently the combination of statin with ezetimibe clearly showed that diabetic patients benefit from low LDL cholesterol levels. In this context the newly developed proprotein convertase subtilisin kexin 9 (PCSK9) inhibitors are of great interest as they reduce LDL cholesterol by 50-70 % independent of co-medication and largely independent of the underlying dyslipidemia. Subgroup analyses of phase 2 and phase 3 studies indicated that diabetic patients show a similar response to PCSK9 inhibitors as non-diabetic patients. Furthermore, the overall very low rate of side effects seems to be comparable between diabetic and non-diabetic patients. In contrast to statins PCSK9 inhibitors do not lead to an increased rate of new onset diabetes. Although data from safety studies (post hoc analyses) are very promising concerning the prevention of cardiovascular events, data from outcome studies will only become available in 2016. Until then PCSK9 inhibitors should be restricted to patients with very high risk and a significant distance from the LDL cholesterol target values (despite maximum possible lipid-lowering therapy with statins and ezetimibe). This approach will most likely have to be adapted when outcome data are available.

Objectives: Whether whole-body MRI can predict occurrence of recurrent events in patients with diabetes mellitus., Methods: Whole-body MRI was prospectively applied to 61 diabetics and assessed for arteriosclerosis and ischemic cerebral/myocardial changes. Occurrence of cardiocerebral events and diabetic comorbidites was determined. Patients were stratified whether no, a single or recurrent events arose. As a secondary endpoint, events were stratified into organ system-specific groups., Results: During a median follow-up of 70 months, 26 diabetics developed a total of 39 events; 18 (30%) developed one, 8 (13%) recurrent events. Between diabetics with no, a single and recurrent events, a stepwise higher burden was observed for presence of left ventricular (LV) hypo-/akinesia (3/28/75%, p < 0.0001), myocardial delayed-contrast-enhancement (17/33/63%, p = 0.001), carotid artery stenosis (11/17/63%, p = 0.005), peripheral artery stenosis (26/56/88%, p = 0.0006) and vessel score (1.00/1.30/1.76, p < 0.0001). After adjusting for clinical characteristics, LV hypo-/akinesia (hazard rate ratio = 6.57, p < 0.0001) and vessel score (hazard rate ratio = 12.29, p < 0.0001) remained independently associated. Assessing organ system risk, cardiac and cerebral MR findings predicted more strongly events in their respective organ system. Vessel-score predicted both cardiac and cerebral, but not non-cardiocerebral, events., Conclusion: Whole-body MR findings predict occurrence of recurrent events in diabetics independent of clinical characteristics, and may concurrently provide organ system-specific risk., Key Points: • Patients with long-standing diabetes mellitus are at high risk for recurrent events. • Whole-body MRI predicts occurrence of recurrent events independently of clinical characteristics. • The vessel score derived from whole-body angiography is a good general risk-marker. • Whole-body MRI may also provide organ-specific risk assessment. • Current findings may indicate benefits of whole-body MRI for risk stratification.

Background: Many patients with heterozygous familial hypercholesterolemia (HeFH) fail to reach optimal low-density lipoprotein cholesterol (LDL-C) levels with available lipid-lowering medications, including statins, and require treatment using alternative methods such as lipoprotein apheresis., Objective: To evaluate the efficacy of alirocumab 150 mg every 2 weeks (Q2W) compared with placebo in reducing the frequency of lipoprotein apheresis treatments in patients with HeFH., Methods: ODYSSEY ESCAPE is a randomized, double-blind, placebo-controlled, parallel-group, 18-week, phase 3 study being conducted in the United States and Germany. ODYSSEY ESCAPE will evaluate the efficacy and safety of alirocumab in approximately 63 adults with HeFH undergoing regular weekly (QW; for ≥4 weeks) or Q2W (for ≥8 weeks) lipoprotein apheresis. Patients will be randomly assigned (2:1, respectively) to receive alirocumab 150 mg subcutaneously Q2W or placebo subcutaneously Q2W (both in 1-mL injections) for 18 weeks. From day 1 to week 6, the apheresis frequency will be fixed to the individual patient's established schedule (QW or Q2W); thereafter, apheresis will be performed according to the LDL-C value at that visit: apheresis will not be performed when the LDL-C value is ≥30% lower than the baseline pre-apheresis LDL-C value. The primary end point is the frequency of apheresis treatments over a 12-week period starting at week 7., Discussion: The ODYSSEY ESCAPE trial will determine whether alirocumab reduces the frequency of lipoprotein apheresis in patients with HeFH., (Copyright © 2016 National Lipid Association.

Background: Disorders of lipid metabolism are very common. They play an important role in the pathogenesis of atherosclerosis and can be effectively treated by lifestyle changes and drugs., Methods: This review is based on pertinent literature retrieved by a selective search., Results: The main disorders of lipid metabolism are LDL-hypercholesterolemia, hypertriglyceridemia, mixed hyperlipoproteinemia, and low HDL cholesterol. The lipoprotein(a) level can also be elevated either in isolation or in combination with other disorders of lipid metabolism. According to the current European recommendations, an LDL-cholesterol target value should be defined on the basis of the overall cardiovascular risk. If this risk is very high, as in patients with documented atherosclerosis, the target value should be set at <70 mg/dL (<1.8 mmol/L). If the risk is lower, higher target values can be set: <100 mg/dL (<2.6 mmol/L) or <115 mg/dL (<3.0 mmol/L). Lifestyle changes are an effective treatment mainly for patients with hypertriglyceridemia and mixed disorders of lipid metabolism. Lowering the LDL-cholesterol concentration with statins is by far the most important type of pharmacotherapy. Patients who cannot tolerate statins or whose cholesterol level is not adequately lowered can be given ezetimibe instead. PCSK9 antibodies have been available since the autumn of 2015; they can apparently lower the LDL-cholesterol level by more than 50% , but no endpoint trials have yet been reported. At present, they should only be given to carefully selected patients. Fibrates and omega-3 fatty acids have been found to prevent cardiovascular events in monotherapy trials but yield no added benefit when given together with statins. The design of these trials was faulty, however, and the utility of such combinations in patients with mixed disorders of lipid metabolism or hypertriglyceridemia cannot yet be definitively assessed., Conclusion: There is a causal relationship between hypercholesterolemia and the risk of vascular and cardiovascular events. A reduction of LDL cholesterol lessens the risk of cardiovascular events.

Objective: Glucagon-like peptide-1 (GLP-1) is an incretin hormone, which gets secreted in response to nutritional stimuli from the gut mediating glucose-dependent insulin secretion. Interestingly, GLP-1 was recently found to be also increased in response to inflammatory stimuli in an interleukin 6 (IL-6) dependent manner in mice. The relevance of this finding to humans is unknown but has been suggested by the presence of high circulating GLP-1 levels in critically ill patients that correlated with markers of inflammation. This study was performed to elucidate, whether a direct link exists between inflammation and GLP-1 secretion in humans., Research Design and Methods: We enrolled 22 non-diabetic patients scheduled for cardiac surgery as a reproducible inflammatory stimulus with repeated blood sampling before and after surgery., Results: Mean total circulating GLP-1 levels significantly increased in response to surgery from 25.5 ± 15.6 pM to 51.9 ± 42.7 pM which was not found in a control population. This was preceded by an early rise of IL6, which was significantly associated with GLP-1 under inflammatory but not basal conditions. Using repeated measure ANCOVA, IL6 best predicted the observed kinetics of GLP-1, followed by blood glucose concentrations and cortisol plasma levels. Furthermore, GLP-1 plasma concentrations significantly predicted endogenous insulin production as assessed by C-peptide concentrations over time, while an inverse association was found for insulin infusion rate., Conclusion: We found GLP-1 secretion to be increased in response to inflammatory stimuli in humans, which was associated to parameters of glucose metabolism and best predicted by IL6.

Objectives: Postprandial atherogenic lipoproteins, characterizing high-risk patients, correlate positively with cardiovascular events. Although the effect of niacin on fasting lipids is well established, its impact on atheroprotective reverse cholesterol transport (RCT) pathway and on functional features of circulating lipoproteins during the postprandial state remains indeterminate., Approach and Results: We evaluated RCT pathway during postprandial phase in dyslipidemic patients displaying a low high-density lipoprotein (HDL) cholesterol phenotype. Ten subjects on stable statin therapy received 1 g/20 mg extended-release niacin/laropiprant (ERN/LRPT) for 4 weeks followed by 2 g/40 mg ERN/LRPT for additional 8 weeks. At each experimental period, postprandial hypertriglyceridemia and major steps of RCT, including cholesterol efflux from human macrophages, cholesteryl ester transfer protein-mediated cholesteryl ester transfer, and hepatic HDL-cholesteryl ester selective uptake were evaluated. Equally, the capacity of postprandial HDL particles isolated from patients before and after ERN/LRPT treatment to mediate RCT to feces was evaluated in vivo in human apolipoprotein B/cholesteryl ester transfer protein double transgenic mouse model. Compared with baseline, ERN/LRPT significantly reduced postprandial hypertriglyceridemia (incremental area under the curve-triglyceride: -53%; P=0.02). Postprandial increase in endogenous plasma cholesteryl ester transfer protein activity was completely abolished after ERN/LRPT treatment. Despite a slight reduction in plasma cholesterol efflux capacity from human THP-1 macrophages, evaluation of global RCT efficacy by combining both ex vivo and in vivo approaches indicate that postprandial HDL particles formed under ERN/LRPT therapy displayed a greater capacity for HDL-mediated RCT to feces., Conclusions: ERN/LRPT treatment efficiently attenuates atherogenic postprandial lipemia and stimulates HDL-mediated cholesterol return to the liver and elimination into feces during postprandial phase, thus maintaining an efficient removal of cholesterol from the body., (© 2015 American Heart Association, Inc.)

Aim: To explore the frequency of hypoglycaemic episodes, their risk factors, and associations with patient-reported outcomes in patients with type 2 diabetes enrolled in the PANORAMA cross-sectional study., Methods: Five thousand seven hundred and eighty-three patients aged ≥ 40 years with type 2 diabetes duration ≥ 1 year were recruited in nine European countries. Patients reported severe and non-severe hypoglycaemic episodes during the past year at a single study visit. Patient-reported outcomes were measured by the Audit of Diabetes-Dependent Quality of Life, Diabetes Treatment Satisfaction Questionnaires, Hypoglycaemia Fear Survey-II, and EQ-5D Visual Analog Scale., Results: During the previous year, 4.4% of the patients experienced ≥ 1 severe hypoglycaemic episode; among those without severe hypoglycaemia, 15.7% experienced ≥ 1 non-severe episode. Patients experiencing any hypoglycaemic episode reported a greater negative impact of diabetes on quality of life, greater fear of hypoglycaemia, less treatment satisfaction and worse health status than those with no episodes. In multivariate analyses hypoglycaemia was significantly associated with longer diabetes duration; presence of microvascular and, to a lesser extent, macrovascular complications; treatment with insulin, glinides or sulfonylureas; and use of self-monitoring blood glucose., Conclusion: In patients with type 2 diabetes, severe hypoglycaemic episodes were not uncommon and one in five experienced some form of hypoglycaemia during the previous year. Hypoglycaemia was associated with more negative patient-reported outcomes. The risk of hypoglycaemia increased with diabetes duration, presence of diabetes-related complications, use of self-monitoring blood glucose, insulin secretagogues, and insulin treatment., (Copyright © 2015 Elsevier Masson SAS.

We report the successful treatment of autoimmune hypoglycemia in an 82-year-old non-diabetic Caucasian male with hydrothermally modified slow release corn starch, a product which is used in other conditions associated with hypoglycemia, most typically glycogen storage disease type I. An 82-year-old-Caucasian male presented with recurrent spontaneous hypoglycemia as low as 30 mg/dl following in-patient treatment for community acquired pneumonia. During a fasting-test, symptomatic hypoglycemia occurred. Plasma concentrations of c-peptide and insulin were considerably elevated. Autoimmune hypoglycemia was confirmed by the presence of insulin autoantibodies. While dietary restriction alone did not result in sufficient glucose control in this patient with autoimmune hypoglycemia, treatment with hydrothermally modified slow release corn starch led to stable euglycemia. This easy, well tolerated and non-invasive treatment may constitute a new therapeutic option for hypoglycemia in patients with autoimmune hypoglycemia who do not achieve sufficient control of hypoglycemia by dietary restriction alone.

Context: Familial hypobetalipoproteinemia (FHBL) is a codominant disorder of lipoprotein metabolism characterized by decreased plasma concentrations of low-density lipoprotein (LDL)-cholesterol and apolipoprotein B (apoB)., Objective: The objective was to examine the effect of heterozygous APOB L343V FHBL on postprandial triglyceride-rich lipoprotein (TRL) and fasting lipoprotein metabolism., Methods: Plasma incremental area under the curve apoB-48 and apoB-48 kinetics were determined after ingestion of a standardized oral fat load using compartmental modeling. Very low-density lipoprotein (VLDL)-, intermediate-density lipoprotein (IDL)-, and LDL-apoB kinetics were determined in the fasting state using stable isotope methods and compartmental modeling., Results: The postprandial incremental area under the curve (0-10 h) in FHBL subjects (n = 3) was lower for large TRL-triglyceride (-77%; P < .0001), small TRL-cholesterol (-83%; P < .001), small TRL-triglyceride (-88%; P < .001), and for plasma triglyceride (-70%; P < .01) and apoB (-63%; P < .0001) compared with controls. Compartmental analysis showed that apoB-48 production was lower (-91%; P < .05) compared with controls. VLDL-apoB concentrations in FHBL subjects (n = 2) were lower by more than 75% compared with healthy, normolipidemic control subjects (P < .01). The VLDL-apoB fractional catabolic rate (FCR) was more than 5-fold higher in the FHBL subjects (P = .07). ApoB production rates and IDL- and LDL-apoB FCRs were not different between FHBL subjects and controls., Conclusions: We conclude that when compared to controls, APOB L343V FHBL heterozygotes show lower TRL production with normal postprandial TRL particle clearance. In contrast, VLDL-apoB production was normal, whereas the FCR was higher in heterozygotes compared with lean control subjects. These mechanisms account for the marked hypolipidemic state observed in these FHBL subjects.

Glucose and lipid metabolism are linked to each other in many ways. The most important clinical manifestation of this interaction is diabetic dyslipidemia, characterized by elevated triglycerides, low high density lipoprotein cholesterol (HDL-C), and predominance of small-dense LDL particles. However, in the last decade we have learned that the interaction is much more complex. Hypertriglyceridemia and low HDL-C cannot only be the consequence but also the cause of a disturbed glucose metabolism. Furthermore, it is now well established that statins are associated with a small but significant increase in the risk for new onset diabetes. The underlying mechanisms are not completely understood but modulation of 3-hydroxy-3-methylglutaryl-coenzyme A (HMG CoA)-reductase may play a central role as genetic data indicate that mutations resulting in lower HMG CoA-reductase activity are also associated with obesity, higher glucose concentrations and diabetes. Very interestingly, this statin induced increased risk for new onset type 2 diabetes is not detectable in subjects with familial hypercholesterolemia. Furthermore, patients with familial hypercholesterolemia seem to have a lower risk for type 2 diabetes, a phenomenon which seems to be dose-dependent (the higher the low density lipoprotein cholesterol, the lower the risk). Whether there is also an interaction between lipoprotein(a) and diabetes is still a matter of debate.

Familial hypercholesterolaemia (FH) is a common genetic cause of premature coronary heart disease (CHD). Globally, one baby is born with FH every minute. If diagnosed and treated early in childhood, individuals with FH can have normal life expectancy. This consensus paper aims to improve awareness of the need for early detection and management of FH children. Familial hypercholesterolaemia is diagnosed either on phenotypic criteria, i.e. an elevated low-density lipoprotein cholesterol (LDL-C) level plus a family history of elevated LDL-C, premature coronary artery disease and/or genetic diagnosis, or positive genetic testing. Childhood is the optimal period for discrimination between FH and non-FH using LDL-C screening. An LDL-C ≥5 mmol/L (190 mg/dL), or an LDL-C ≥4 mmol/L (160 mg/dL) with family history of premature CHD and/or high baseline cholesterol in one parent, make the phenotypic diagnosis. If a parent has a genetic defect, the LDL-C cut-off for the child is ≥3.5 mmol/L (130 mg/dL). We recommend cascade screening of families using a combined phenotypic and genotypic strategy. In children, testing is recommended from age 5 years, or earlier if homozygous FH is suspected. A healthy lifestyle and statin treatment (from age 8 to 10 years) are the cornerstones of management of heterozygous FH. Target LDL-C is <3.5 mmol/L (130 mg/dL) if >10 years, or ideally 50% reduction from baseline if 8-10 years, especially with very high LDL-C, elevated lipoprotein(a), a family history of premature CHD or other cardiovascular risk factors, balanced against the long-term risk of treatment side effects. Identifying FH early and optimally lowering LDL-C over the lifespan reduces cumulative LDL-C burden and offers health and socioeconomic benefits. To drive policy change for timely detection and management, we call for further studies in the young. Increased awareness, early identification, and optimal treatment from childhood are critical to adding decades of healthy life for children and adolescents with FH., (© The Author 2015.

The gut microbiota has been linked to metabolic diseases. However, information on the microbiome of young adults at risk for type 2 diabetes (T2D) is lacking. The aim of this cross-sectional analysis was to investigate whether insulin resistant women with previous gestational diabetes (pGDM), a high risk group for T2D, differ in their stool microbiota from women after a normoglycemic pregnancy (controls). Bacterial communities were analyzed by high-throughput 16S rRNA gene sequencing using fecal samples from 42 pGDM and 35 control subjects 3-16 months after delivery. Clinical characterization included a 5-point OGTT, anthropometrics, clinical chemistry markers and a food frequency questionnaire. Women with a Prevotellaceae-dominated intestinal microbiome were overrepresented in the pGDM group (p < 0.0001). Additionally, the relative abundance of the phylum Firmicutes was significantly lower in women pGDM (median 48.5 vs. 56.8%; p = 0.013). Taxa richness (alpha diversity) was similar between the two groups and with correction for multiple testing we observed no significant differences on lower taxonomic levels. These results suggest that distinctive features of the intestinal microbiota are already present in young adults at risk for T2D and that further investigations of a potential pathophysiological role of gut bacteria in early T2D development are warranted.

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 non-cholesterol 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., (© The European Society of Cardiology 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.)

We analyzed the association of sleep quality and glucose metabolism in women after gestational diabetes (pGDM) and in women after normoglycemic pregnancy (controls). Data during pregnancy and a visit within the first 15 months after delivery were collected from 61 pGDM and 30 controls in a prospective cohort study. This included a medical history, physical examination, questionnaires (Pittsburgh Sleep Quality Index (PSQI), and Perceived Stress Scale (PSS)), and 5-point oral glucose tolerance test with insulin measurements to determine indices of insulin sensitivity and insulin secretion. We used Spearman correlation coefficients and multivariate regression models for analysis.9.3 ± 3.2 months after delivery, pGDM had significantly higher fasting and 2 h glucose levels and lower insulin sensitivity than controls. There was no significant difference in age, BMI and sleep quality as assessed with the PSQI between the two groups. The PSQI score correlated with the ogtt-2 h plasma glucose in pGDM (δ = 0.41; p = 0.0012), but not in controls. This association was confirmed with a multivariate linear regression model with adjustment for age, BMI and months post-delivery. Perceived stress was an independent risk factor (OR 1.12; 95% CI 1.02-1.23) for impaired sleep. Our findings suggest that post-delivery sleep quality significantly influences glucose tolerance in women after GDM and that impaired sleep is associated with increased stress perception. Measures to improve of sleep quality and reduce perceived stress should therefore be tested as additional strategies to prevent progression to type 2 diabetes after GDM., (Copyright © 2015 Elsevier Ltd.

Context: The pathogenesis of type 2 diabetes (T2D) is still incompletely understood. In-depth phenotyping of young individuals at risk for T2D can contribute to the understanding of this process., Objective: The purpose of this study was to metabolically characterize women with recent gestational diabetes (GDM), an at-risk cohort for T2D., Study Participants: Participants were 147 women consecutively recruited 3 to 16 months after pregnancy: women who had GDM and women after a normoglycemic pregnancy (control subjects) in a 2:1 ratio., Design: This was a monocenter cross-sectional analysis (Prediction, Prevention and Subclassification of Type 2 Diabetes Study [PPS-Diab])., Methods: A 5-point oral glucose tolerance test with calculation of the insulin sensitivity index and disposition index (validation by euglycemic clamp and intravenous glucose tolerance test) was performed. In addition, anthropometrics, medical and family history, clinical chemistry and biomarkers, statistical modeling, and a magnetic resonance imaging/magnetic resonance spectroscopy substudy (body fat distribution and liver and muscle fat; n = 66) were obtained., Results: Compared with control subjects, women after GDM had a reduced disposition index, higher levels of plasma fetuin-A, and a lower insulin sensitivity index. A low insulin sensitivity index was also the major determinant of pathological glucose tolerance after GDM. The factors most strongly predictive of low insulin sensitivity were high plasma leptin, body mass index, triglycerides, and waist circumference. Ectopic lipids showed no body mass index-independent associations with having had GDM or low insulin sensitivity in a magnetic resonance imaging substudy., Conclusions: We found that β-cell function is already impaired in women with recent GDM, a young at-risk cohort for T2D. In addition, our data suggest that fetuin-A and leptin signaling may be important early contributors to the pathogenesis of T2D, at this disease stage equally or more relevant than ectopic lipids and low-grade inflammation.
