Abstract
BACKGROUND The role of proprotein convertase subtilisin/kexin type 9 (PCSK9) in dyslipidemia may go beyond its immediate effects on low-density lipoprotein receptor (LDL-R) activity. OBJECTIVE This study aimed to assess PCSK9-derived alterations of high-density lipoprotein (HDL) physiology, which bear a potential to contribute to cardiovascular risk profile. METHODS HDL was isolated from 33 patients with familial autosomal dominant hypercholesterolemia (FH), including those carrying PCSK9 gain-of-function (GOF) genetic variants (FH-PCSK9, n = 11), together with two groups of dyslipidemic patients employed as controls and carrying genetic variants in the LDL-R not treated (ntFH-LDLR, n = 11) and treated (tFH-LDLR, n = 11) with statins, and 11 normolipidemic controls. Biological evaluations paralleled by proteomic, lipidomic and glycomic analyses were applied to characterize functional and compositional properties of HDL. RESULTS Multiple deficiencies in the HDL function were identified in the FH-PCSK9 group relative to dyslipidemic FH-LDLR patients and normolipidemic controls, which involved reduced antioxidative, antiapoptotic, anti-thrombotic and anti-inflammatory activities. By contrast, cellular cholesterol efflux capacity of HDL was unchanged. In addition, multiple alterations of the proteomic, lipidomic and glycomic composition of HDL were found in the FH-PCSK9 group. Remarkably, HDLs from FH-PCSK9 patients were systematically enriched in several lysophospholipids as well as in A2G2S2 (GP13) glycan and apolipoprotein A-IV. Based on network analysis of functional and compositional data, a novel mosaic structure-function model of HDL biology involving FH was developed. CONCLUSION Several metrics of anti-atherogenic HDL functionality are altered in FH-PCSK9 patients paralleled by distinct compositional alterations. These data provide a first-ever overview of the impact of GOF PCSK9 genetic variants on structure-function relationships in HDL.

Abstract
Ceramides (Cer) have been shown as lipotoxic inducers, which disturb numerous cell-signaling pathways, leading to metabolic disorders such as type 2 diabetes. In this study, we aimed to determine the role of de novo hepatic ceramide synthesis in energy and liver homeostasis in mice. We generated mice lacking serine palmitoyltransferase 2 (Sptlc2), the rate limiting enzyme of ceramide de novo synthesis, in liver under albumin promoter. Liver function, glucose homeostasis, bile acid (BA) metabolism and hepatic sphingolipids content were assessed using metabolic tests and LC-MS. Despite lower expression of hepatic Sptlc2, we observed an increased concentration of hepatic Cer, associated with a 10-fold increase in neutral sphingomyelinase 2 (nSMase2) expression, and a decreased sphingomyelin content in the liver. Sptlc2ΔLiv mice were protected against obesity induced by high fat diet and displayed a defect in lipid absorption. In addition, an important increase in tauro-muricholic acid was associated with a downregulation of the nuclear BA receptor FXR target genes. Sptlc2 deficiency also enhanced glucose tolerance and attenuated hepatic glucose production, while the latter effect was dampened in presence of nSMase2 inhibitor. Finally, Sptlc2 disruption promoted apoptosis, inflammation and progressive development of hepatic fibrosis, worsening with age. Our data suggest a compensatory mechanism to regulate hepatic ceramides content from sphingomyelin hydrolysis, with deleterious impact on liver homeostasis. In addition, our results show the involvement of hepatic sphingolipid modulation in BA metabolism and hepatic glucose production in an insulin-independent manner, which highlight the still under-researched role of ceramides in many metabolic functions.

Abstract
Aim: This online interactive survey investigated lipid-lowering approaches of French cardiologists in high- and very high-cardiovascular risk patients with hypercholesterolemia. Materials & methods: Physicians assessed three hypothetical patients at three clinic visits, and selected the patients' cardiovascular risk category, target low-density lipoprotein cholesterol (LDL-C) and treatment. Results: A total of 162 physicians completed 480 risk assessments; 58% of assessments correctly categorized the hypothetical patients. Most physicians chose the correct LDL-C target for one of the very high-risk patients, but higher-than-recommended targets were selected for the other very high-risk patient and the high-risk patient. Statins were the most commonly chosen treatment. Conclusion: French cardiologists often underestimate cardiovascular risk in patients with hypercholesterolemia, select a higher-than-recommended LDL-C target and prescribe less intensive treatment than that recommended by guidelines.

Abstract
AIM Lipoprotein(a) (Lp(a)) is a low-density lipoprotein-like particle containing apolipoprotein(a) (apo(a)) that increases the risk of atherosclerotic cardiovascular disease (ASCVD) in familial hypercholesterolemia (FH). Postprandial redistribution of apo(a) protein from Lp(a) to triglyceride-rich lipoproteins (TRLs) may also increase the atherogenicity of TRL particles. Omega-3 fatty acid (ω3FA) supplementation improves postprandial TRL metabolism in FH subjects. However, its effect on postprandial apo(a) metabolism has yet to be investigated. METHODS We carried out an 8-week open-label, randomized, crossover trial to test the effect of ω3FA supplementation (4 g/day) on postprandial apo(a) responses in FH patients following ingestion of an oral fat load. Postprandial plasma total and TRL-apo(a) concentrations were measured by liquid chromatography with tandem mass spectrometry, and the corresponding areas under the curve (AUCs) (0-10h) were determined using the trapezium rule. RESULTS Compared with no ω3FA treatment, ω3FA supplementation significantly lowered the concentrations of postprandial TRL-apo(a) at 0.5 (-17.9%), 1 (-18.7%), 2 (-32.6%), and 3 h (-19.2%) (P<0.05 for all). Postprandial TRL-apo(a) AUC was significantly reduced with ω3FA by 14.8% (P<0.05). By contrast, ω3FA had no significant effect on the total AUCs of apo(a), apoC-III, and apoE (P>0.05 for all). The decrease in postprandial TRL-apo(a) AUC was significantly associated with changes in the AUC of triglycerides (r=0.600; P<0.01) and apoB-48 (r=0.616; P<0.01). CONCLUSIONS Supplementation with ω3FA reduces postprandial TRL-apo(a) response to a fat meal in FH patients; this novel metabolic effect of ω3FA may have implications on decreasing the risk of ASCVD in patients with FH, especially in those with elevated plasma triglyceride and Lp(a) concentrations. However, the clinical implications of these metabolic findings require further evaluation in outcome or surrogate endpoint trials.

Abstract
BACKGROUND Animal studies have demonstrated that fetal exposure to high maternal cholesterol levels during pregnancy predisposes to aortic atheroma in the offspring. In humans, little is known about the consequences of this exposure on the development of atherosclerotic cardiovascular disease later in life. We wanted to assess whether maternal/paternal inheritance of familial hypercholesterolemia (FH) gene mutation could be associated with subclinical coronary atherosclerosis. METHODS We retrospectively included 1350 patients, followed in the French registry of FH, with a documented genetic diagnosis. We selected 556 age- and sex-matched pair of patients based on the sex of the parents who transmitted the FH gene mutation, free of coronary cardiovascular event, and with a subclinical coronary atherosclerosis evaluation assessed using coronary artery calcium (CAC) score. We performed univariate and multivariate analysis to assess the individual effect of parental inheritance of the FH gene mutation on the CAC score. RESULTS In the whole population, patients with maternal inheritance of FH gene mutation (n=639) less frequently had a family history of premature cardiovascular events (27.7% versus 45%, P<0.0001) and were 2 years older (46.9±16.8 versus 44.7±15.9 years old, P=0.02) than those with paternal inheritance (n=711). There was no difference in the prevalence of cardiovascular events between the two groups. In the matched subgroup, maternal inheritance was significantly associated with an increase in CAC score value by 86% (95% CI, 23%-170%; P=0.003), a 1.81-fold risk of having a CAC score ≥100 Agatston units (95% CI, 1.06-3.11; P=0.03), and a 2.72-fold risk of having a CAC score ≥400 Agatston units (95% CI, 1.39-5.51; P=0.004) when compared with paternal inheritance in multivariate analysis. CONCLUSIONS Maternal inheritance of FH gene mutation was associated with more severe subclinical coronary atherosclerosis assessed by CAC score and may be considered as a potential cardiovascular risk factor.

Abstract
BACKGROUND Lysosomal acid lipase deficiency (LALD, OMIM#278000) is a rare lysosomal disorder with an autosomal recessive inheritance. The main clinical manifestations are related to a progressive accumulation of cholesteryl esters, triglycerides or both within the lysosome in different organs such as the liver, spleen, and cardiovascular system. A wide range of clinical severity is associated with LALD including a severe very rare antenatal/neonatal/infantile phenotype named Wolman disease and a late-onset form named cholesteryl ester storage disease (CESD). METHODS This study aimed to investigate a cohort of at-risk patients (4174) presenting with clinical or biological signs consistent with LALD using the assessment of LAL activity on dried blood spots. RESULTS LAL activity was lower than 0.05 nmol/punch/L (cut-off: 0.12) in 19 patients including 13 CESD and 6 Wolman. Molecular study has been conducted in 17 patients and succeeded in identifying 34 mutated alleles. Fourteen unique variants have been characterized, 7 of which are novel. CONCLUSION This study allowed to identify a series of patients and expanded the molecular spectrum knowledge of LALD. Besides, a new screening criteria grid based on the clinical/biological data from our study and the literature has been proposed in order to enhance the diagnosis rate in at risk populations.

Abstract
CONTEXT The relative incidence of acute pancreatitis, ischemic cardiovascular disease, and diabetes in hyperchylomicronemic patients exhibiting familial chylomicronemia syndrome (FCS) or multifactorial chylomicronemia syndrome (MCS) is unknown. OBJECTIVE The objective was to study the occurrence of these events in FCS and MCS patients compared with the general population. METHODS Twenty-nine FCS and 124 MCS patients, with genetic diagnosis, in 4 lipid clinics were matched with 413 controls. Individual hospital data linked to the national claims database were collected between 2006 and 2016. The occurrence of complications was retrospectively assessed before follow-up and during a median follow-up time of 9.8 years, for 1500 patient years of follow-up. RESULTS Patients with FCS were younger than those with MCS (34.3 ± 13.6 vs 45.2 ± 12.6 years, P < 0.01). During the study period, 58.6% of the FCS patients versus 19.4% of the MCS patients had at least 1 episode of acute hypertriglyceridemic pancreatitis (AHP) (hazard ratio [HR] = 3.6; P < 0.01). Conversely, the ischemic risk was lower in FCS than in MCS (HR = 0.3; P = 0.05). The risk of venous thrombosis was similar in both groups. The incidence of diabetes was high in both groups compared with matched controls (odds ratio [OR] = 22.8; P < 0.01 in FCS and OR = 30.3; P < 0.01 in MCS). CONCLUSION The incidence of AHP was much higher in FCS than in MCS patients, whereas the incidence of ischemic cardiovascular events was found to be increased in MCS versus FCS patients and a representative matched control group. Differences in both triglyceride-rich lipoproteins metabolism and comorbidities in MCS versus FCS drive the occurrence of different patterns of complications.

Abstract
Aims
To improve attainment of LDL-cholesterol (LDL-c) targets, an expert group proposed an algorithm for lipid-lowering therapy during hospitalization for acute coronary syndrome and during follow-up. We aimed to assess adherence to this algorithm, and evaluate its impact on LDL-c levels and on attainment of therapeutic LDL-c targets in a population of post-acute coronary syndrome patients.
Methods and results
Prospective, observational study including patients admitted for acute coronary syndrome between February 2017 and September 2018. Patients admitted without statins or ezetimibe were considered ‘naïve’. Baseline LDL-c was admission LDL-c in naïve patients, and for those taking lipid-lowering therapy at admission, baseline LDL-c was back-calculated. In line with the most recent guidelines, the target was a >50% reduction in naïve LDL-c and <55 mg/dL. In total, 270 patients were analysed, mean age 67 ± 12 years, 78% men, 26% diabetic. At admission, 175 (65%) were naïve, 95 (35%) had previous lipid-lowering therapy, of which 13 (5%) statin+ezetimibe. Average LDL-c at admission was 120 ± 47 mg/dL (136 ± 44 mg/dL in naïve, 91 ± 39 mg/dL in pretreated patients). Discharge prescription was in compliance with the algorithm in 204 (76%) patients. Average LDL-c at two months was 57 ± 28 mg/dL; it was <55 mg/dL in 135 (50%), and 178 (66%) achieved a >50% reduction. Overall, 125/270 (46%) achieved the LDL-c goal. The reduction in LDL-c observed at two months persisted at five months.
Conclusion
Prescription of high-intensity statins, associated with ezetimibe where applicable, achieves LDL-c levels <55 mg/dL in 50% of patients at two months, and attains therapeutic goals defined by the European Society of Cardiology in 46% of cases.

Abstract
Abstract
In patients admitted for acute myocardial infarction, the communication and transition from specialists to primary care physicians is often delayed, and the information imparted to subsequent healthcare providers (HCPs) may be sub-optimal. A French group of cardiologists, lipidologists and diabetologists decided to establish a consensus to optimize the discharge letter after hospitalization for acute myocardial infarction. The aim is to improve both the timeframe and the quality of the content transmitted to subsequent HCPs, including information regarding baseline assessment, procedures during hospitalization, residual risk, discharge treatments, therapeutic targets and follow-up recommendations in compliance with European Society of Cardiology guidelines. A consensus was obtained regarding a template discharge letter, to be released within two days after patient’s discharge, and containing the description of the patient’s history, risk factors, acute management, risk assessment, discharge treatments and follow-up pathway. Specifically for post acute MI patients, tailored details are necessary regarding the antithrombotic regimen, lipid-lowering and anti-diabetic treatments, including therapeutic targets. Lastly, the follow-up pathway needs to be precisely mentioned in the discharge letter. Additional information such as technical descriptions, imaging, and quality indicators may be provided separately. A template for a standardized discharge letter based on 8 major headings could be useful for implementation in routine practice and help to improve the quality and timing of information transmission between HCPs after acute MI.

Abstract
CONTEXT Evidence for an association between sphingolipids and metabolic disorders is increasingly reported. Omega-3 long-chain polyunsaturated fatty acids (n-3 LC-PUFAs) improve apolipoprotein B100 (apoB100)-containing lipoprotein metabolism, but their effects on the sphingolipid content in lipoproteins remain unknown. OBJECTIVES In subjects with hypertriglyceridemia, we analyzed the effect of n-3 LC-PUFAs on the turnover apoB100-containing lipoproteins and on their sphingolipid content and looked for the possible association between these lipid levels and apoB100-containing lipoprotein turnover parameters. METHODS Six subjects underwent a kinetic study before and after n-3 supplementation for 2 months with 1 g of fish oil 3 times day containing 360 mg of eicosapentaenoic acid (EPA) and 240 mg of docosahexaenoic acid (DHA) in the form of triglycerides. We examined apoB100-containing lipoprotein turnover by primed perfusion labeled [5,5,5-2H3]-leucine and determined kinetic parameters using a multicompartmental model. We quantified sphingolipid species content in lipoproteins using mass spectrometry. RESULTS Supplementation decreased very low-density lipoprotein (VLDL), triglyceride, and apoB100 concentrations. The VLDL neutral and polar lipids showed increased n-3 LC-PUFA and decreased n-6 LC-PUFA content. The conversion rate of VLDL1 to VLDL2 and of VLDL2 to LDL was increased. We measured a decrease in total apoB100 production and VLDL1 production. Supplementation reduced the total ceramide concentration in VLDL while the sphingomyelin content in LDL was increased. We found positive correlations between plasma palmitic acid and VLDL ceramide and between VLDL triglyceride and VLDL ceramide, and inverse correlations between VLDL n-3 LC-PUFA and VLDL production. CONCLUSION Based on these results, we hypothesize that the improvement in apoB100 metabolism during n-3 LC-PUFA supplementation is contributed to by changes in sphingolipids.

Abstract
The aim of this study was to compare the kinetics of apolipoprotein (apo)A-I during fed and fasted states in humans, and to determine to what extent the intestine contributes to apoA-I production. A stable isotope study was conducted to determine the kinetics of apoA-I in preβ1 high-density lipoprotein (HDL) and α-HDL. Six healthy male subjects received a constant intravenous infusion of 2H3-leucine for 14 h. Subjects in the fed group also received small hourly meals. Blood samples were collected hourly during tracer infusion and then daily for 4 days. Tracer enrichments were measured by mass spectrometry and then fitted to a compartmental model using asymptotic plateau of very-low-density lipoprotein (VLDL) apoB100 and triglyceride-rich lipoprotein (TRL) apoB48 as estimates of hepatic and intestinal precursor pools, respectively. The clearance rate of preβ1-HDL-apoA-I was lower in fed individuals compared with fasted subjects (p < 0.05). No other differences in apoA-I production or clearance rates were observed between the groups. No significant correlation was observed between plasma apoC-III concentrations and apoA-I kinetic data. In contrast, HDL-apoC-III was inversely correlated with the conversion of α-HDL to preβ1-HDL. Total apoA-I synthesis was not significantly increased in fed subjects. Hepatic production was not significantly different between the fed group (17.17 ± 2.75 mg/kg/day) and the fasted group (18.67 ± 1.69 mg/kg/day). Increase in intestinal apoA-I secretion in fed subjects was 2.20 ± 0.61 mg/kg/day. The HDL-apoA-I kinetics were similar in the fasted and fed groups, with 13% of the total apoA-I originating from the intestine with feeding.

Abstract
OBJECTIVE Even though trimethylamine N-oxide (TMAO) has been demonstrated to interfere with atherosclerosis and diabetes pathophysiology, the association between TMAO and major adverse cardiovascular events (MACE) has not been specifically established in type 2 diabetes (T2D). RESEARCH DESIGN AND METHODS We examined the association of plasma TMAO concentrations with MACE and all-cause mortality in a single-center prospective cohort of consecutively recruited patients with T2D. RESULTS The study population consisted in 1463 SURDIENE participants (58% men), aged 65 ± 10 years. TMAO concentrations were significantly associated with diabetes duration, renal function, high-density lipoprotein cholesterol, soluble tumor necrosis factor receptor 1 (sTNFR1) concentrations (R2 = 0.27) and were significantly higher in patients on metformin, even after adjustment for estimated glomerular filtration rate (eGFR): 6.7 (8.5) vs 8.5 (13.6) µmol/L, respectively (PeGFR-adjusted = 0.0207). During follow-up (median duration [interquartile range], 85 [75] months), 403 MACE and 538 deaths were registered. MACE-free survival and all-cause mortality were significantly associated with the quartile distribution of TMAO concentrations, patients with the highest TMAO levels displaying the greatest risk of outcomes (P < 0.0001). In multivariate Cox models, compared with patients from the first 3 quartiles, those from the fourth quartile of TMAO concentration had an independently increased risk for MACE: adjusted hazard ratio (adjHR) 1.32 (1.02-1.70); P = 0.0325. Similarly, TMAO was significantly associated with mortality in multivariate analysis: adjHR 1.75 (1.17-2.09); P = 0.0124, but not when sTNFR1 and angiopoietin like 2 were considered: adjHR 1.16 (0.95-1.42); P = 0.1514. CONCLUSIONS We revealed an association between higher TMAO concentrations and increased risk of MACE and all-cause mortality, thereby opening some avenues on the role of dysbiosis in cardiovascular risk, in T2D patients.

Abstract
Vertical banded gastroplasty (VBG), introduced by Mason in 1982, is now discarded because of important long-term complications and technical difficulties to do revisional surgery. We investigated the long-term complications of VBG in our center and compared it with the literature data. Patients who underwent an open VBG at the University Hospital of Nantes between October 1991 and May 2006 were included. We reviewed preoperative clinical data, long-term outcome in weight loss, complications, and revisional surgeries with a long follow-up. Sixty-three patients (52 women and 11 men) were included, with a mean age of 43 ± 10 years and a body mass index of 46.7 ± 8.3 kg/m. The mean follow-up was 8.2 ± 4.2 years. At the end of follow-up, the mean excess weight loss (EWL) was 29.8%. Long-term success (excess weight loss > 50%) of the procedure was observed in 25 patients (39.7%). A second intervention was performed in 15 patients (23.8%), and three needed a third redo procedure. Six patients (40%) had this new intervention for late complications, and nine (60%) for weight regain. Weight loss is satisfying in the long term although the rate of reintervention is high. Long-term complication can be severe, especially with gastric stenosis that could lead to esophageal cancer. A second reintervention could be technically demanding, especially by laparoscopy, and the patients should be referred to a specialized center.

Abstract
Apolipoproteins govern lipoprotein metabolism and are promising biomarkers of metabolic and cardiovascular diseases. Unlike immunoassays, MS enables the quantification and phenotyping of multiple apolipoproteins. Hence, here, we aimed to develop a LC-MS/MS assay that can simultaneously quantitate 18 human apolipoproteins [A-I, A-II, A-IV, A-V, B48, B100, C-I, C-II, C-III, C-IV, D, E, F, H, J, L1, M, and (a)] and determined apoE, apoL1, and apo(a) phenotypes in human plasma and serum samples. The plasma and serum apolipoproteins were trypsin digested through an optimized procedure and peptides were extracted and analyzed by LC-MS/MS. The method was validated according to standard guidelines in samples spiked with known peptide amounts. The LC-MS/MS results were compared with those obtained with other techniques, and reproducibility, dilution effects, and stabilities were also assessed. Peptide markers were successfully selected for targeted apolipoprotein quantification and phenotyping. After optimization, the assay was validated for linearity, lower limits of quantification, accuracy (biases: -14.8% to 12.1%), intra-assay variability [coefficients of variation (CVs): 1.5-14.2%], and inter-assay repeatability (CVs: 4.1-14.3%). Bland-Altman plots indicated no major statistically significant differences between LC-MS/MS and other techniques. The LC-MS/MS results were reproducible over five repeated experiments (CVs: 1.8-13.7%), and we identified marked differences among the plasma and serum samples. The LC-MS/MS assay developed here is rapid, requires only small sampling volumes, and incurs reasonable costs, thus making it amenable for a wide range of studies of apolipoprotein metabolism. We also highlight how this assay can be implemented in laboratories.

Abstract
Autosomal dominant hypercholesterolemia results from mutations affecting the low-density lipoprotein receptor pathway, including proprotein convertase subtilisin/kexin type 9 (PCSK9) gain-of-function mutations (GoFm) and apolipoprotein B (APOB) loss-of-function mutations (LoFm). This study examined the long-term efficacy and safety of alirocumab in patients with PCSK9 GoFm and APOB LoFm who participated in the open-label extension to a Phase 2 double-blind study (NCT01604824). Of the 23 patients who completed the 14-week double-blind period and 8-week follow-up, 21 opted to continue in the open-label extension (PCSK9 GoFm, n = 15; APOB LoFm, n = 6). Patients received alirocumab 150 mg every 2 weeks from week 32 up to 3 years for PCSK9 GoFm and 2 years for APOB LoFm. Mean duration of alirocumab exposure was 129 weeks (median: 144 weeks). After initiation of alirocumab treatment, low-density lipoprotein cholesterol (LDL-C) decreased in both groups. At week 80, mean percent reduction in LDL-C from baseline was 58.0% and 47.1% for PCSK9 GoFm and APOB LoFm groups, respectively. Treatment-emergent adverse events were reported in 19 patients (90.5%); no patients discontinued treatment due to treatment-emergent adverse events. In patients with autosomal dominant hypercholesterolemia and elevated LDL-C levels despite receiving maximally tolerated lipid-lowering therapies, alirocumab 150 mg every 2 weeks resulted in clinically meaningful reductions in LDL-C, sustained through to 3 years and 2 years for patients with PCSK9 GoFm and APOB LoFm, respectively. Alirocumab was generally well tolerated with no unexpected safety concerns.

Abstract
Objective:
To clarify the association between PCSK9 (proprotein convertase subtilisin/kexin type 9) and Lp(a) (lipoprotein [a]), we studied Lp(a) kinetics in patients with loss-of-function and gain-of-function
PCSK9
mutations and in patients in whom extended-release niacin reduced Lp(a) and PCSK9 concentrations.
Approach and Results:
Six healthy controls, 9 heterozygous patients with familial hypercholesterolemia (5 with low-density lipoprotein receptor [
LDLR
] mutations and 4 with
PCSK9
gain-of-function mutations) and 3 patients with heterozygous dominant-negative
PCSK9
loss-of-function mutations were included in the preliminary study. Eight patients were enrolled in a second study assessing the effects of 2 g/day extended-release niacin. Apolipoprotein kinetics in VLDL (very-low-density lipoprotein), LDL (low-density lipoprotein), and Lp(a) were studied using stable isotope techniques. Plasma Lp(a) concentrations were increased in
PCSK9
-gain-of-function and familial hypercholesterolemia-
LDLR
groups compared with controls and
PCSK9
-loss-of-function groups (14±12 versus 5±4 mg/dL;
P
=0.04), but no change was observed in Lp(a) fractional catabolic rate. Subjects with
PCSK9
-loss-of-function mutations displayed reduced apoE (apolipoprotein E) concentrations associated with a VLDL-apoE absolute production rate reduction. Lp(a) and VLDL-apoE absolute production rates were correlated (
r
=0.50;
P
<0.05). ApoE-to-apolipoprotein (a) molar ratios in Lp(a) increased with plasma Lp(a) (
r
=0.96;
P
<0.001) but not with PCSK9 levels. Extended-release niacin-induced reductions in Lp(a) and VLDL-apoE absolute production rate were correlated (
r
=0.83;
P
=0.015). In contrast, PCSK9 reduction (−35%;
P
=0.008) was only correlated with that of VLDL-apoE absolute production rate (
r
=0.79;
P
=0.028).
Conclusions:
VLDL-apoE production could determine Lp(a) production and/or assembly. As PCSK9 inhibitors reduce plasma apoE and Lp(a) concentrations, apoE could be the link between PCSK9 and Lp(a).

Abstract
AIM Proprotein convertase subtilisin/kexin type 9 (PCSK9) is a master regulator of low-density lipoprotein cholesterol (LDL-C) metabolism, acting as an endogenous inhibitor of the LDL receptor. While it has been shown that bariatric surgery differentially affects plasma LDL-C levels, little is known of its effects on plasma PCSK9 concentrations. Therefore, the present study aimed to: (i) investigate the effect of sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) on plasma PCSK9 concentrations; and (ii) correlate baseline or postoperative plasma PCSK9 concentration variations with anthropometric and metabolic parameters. METHODS Fasting plasma PCSK9 levels were measured by ELISA in morbidly obese patients before and 6 months after bariatric surgery. Patients were recruited from three prospective cohorts (in Nantes and Colombes in France, and Antwerp in Belgium). RESULTS A total of 156 patients (34SG, 122RYGB) were included. Plasma PCSK9, LDL-C and non-high-density lipoprotein cholesterol (non-HDL-C) levels were significantly reduced after RYGB (-19.6%, -16.6% and -19.5%, respectively; P<0.0001), but not after SG. In all patients, postoperative PCSK9 change was positively correlated with fasting plasma glucose (FPG; r=0.22, P=0.007), HOMA-IR (r=0.24, P=0.005), total cholesterol (r=0.17, P=0.037) and non-HDL-C (r=0.17, P=0.038) variations, but not LDL-C. In contrast to what was observed for glucose parameters (FPG, HOMA-IR), correlation between PCSK9 and non-HDL-C changes after RYGB was independent of total weight loss. CONCLUSION RYGB, but not SG, promotes a significant reduction in plasma PCSK9 levels, and such changes in circulating PCSK9 levels after RYGB appear to be more associated with glucose improvement than with lipid homoeostasis parameters.

Abstract
Driving blood glycaemia from hyperglycaemia to euglycaemia as fast as possible while avoiding hypoglycaemia is a major problem for decades for type-1 diabetes and is solved in this study. A control algorithm is designed that guaranties hypoglycaemia avoidance for the first time both from the theory of positive systems point of view and from the most pragmatic clinical practice. The solution consists of a state feedback control law that computes the required hyperglycaemia correction bolus in real-time to safely steer glycaemia to the target. A rigorous proof is given that shows that the control-law respects the positivity of the control and of the glucose concentration error: as a result, no hypoglycaemic episode occurs. The so-called hypo-free strategy control is tested with all the UVA/Padova T1DM simulator patients (i.e. ten adults, ten adolescents, and ten children) during a fasting-night scenario and in a hybrid closed-loop scenario including three meals. The theoretical results are assessed by the simulations on a large cohort of virtual patients and encourage clinical trials.

Abstract
Vertical banded gastroplasty (VBG), introduced by Mason in 1982, is now discarded because of important long-term complications and technical difficulties to do revisional surgery. We investigated the long-term complications of VBG in our center and compared it with the literature data. Patients who underwent an open VBG at the University Hospital of Nantes between October 1991 and May 2006 were included. We reviewed preoperative clinical data, long-term outcome in weight loss, complications, and revisional surgeries with a long follow-up. Sixty-three patients (52 women and 11 men) were included, with a mean age of 43 ± 10 years and a body mass index of 46.7 ± 8.3 kg/m². The mean follow-up was 8.2 ± 4.2 years. At the end of follow-up, the mean excess weight loss (EWL) was 29.8%. Long-term success (excess weight loss > 50%) of the procedure was observed in 25 patients (39.7%). A second intervention was performed in 15 patients (23.8%), and three needed a third redo procedure. Six patients (40%) had this new intervention for late complications, and nine (60%) for weight regain. Weight loss is satisfying in the long term although the rate of reintervention is high. Long-term complication can be severe, especially with gastric stenosis that could lead to esophageal cancer. A second reintervention could be technically demanding, especially by laparoscopy, and the patients should be referred to a specialized center.

Abstract
Gut microbiota-dependent Trimethylamine-N-oxide (TMAO) has been reported to be strongly linked to renal function and to increased cardiovascular events in the general population and in Chronic Kidney Disease (CKD) patients. Considering the lack of data assessing renal handling of TMAO, we conducted this study to explore renal excretion and mechanisms of accumulation of TMAO during CKD. We prospectively measured glomerular filtration rate (mGFR) with gold standard methods and plasma concentrations of trimethylamine (TMA), TMAO, choline, betaine, and carnitine by LC-MS/MS in 124 controls, CKD, and hemodialysis (HD) patients. Renal clearance of each metabolite was assessed in a sub-group of 32 patients. Plasma TMAO was inversely correlated with mGFR (r2 = 0.388, p < 0.001), confirming elevation of TMAO plasma levels in CKD. TMAO clearances were not significantly different from mGFR, with a mean ± SD TMAO fractional excretion of 105% ± 32%. This suggests a complete renal excretion of TMAO by glomerular filtration with a negligible participation of tubular secretion or reabsorption, during all stages of CKD. Moreover, TMAO was effectively removed within 4 h of hemodiafiltration, showing a higher fractional reduction value than that of urea (84.9% ± 6.5% vs. 79.2% ± 5.7%, p = 0.04). This study reports a strong correlation between plasma TMAO levels and mGFR, in CKD, that can be mainly related to a decrease in TMAO glomerular filtration. Clearance data did not support a significant role for tubular secretion in TMAO renal elimination.

Abstract
BACKGROUND Familial hypercholesterolemia is characterized by high levels of low-density lipoprotein cholesterol (LDL-C), and causes of familial hypercholesterolemia include apolipoprotein B (APOB) loss-of-function mutations (LOFm) and proprotein convertase subtilisin/kexin type 9 (PCSK9) gain-of-function mutations (GOFm). OBJECTIVE The aim of this study was to compare the pharmacokinetics and pharmacodynamics of alirocumab between patients with APOB LOFm vs PCSK9 GOFm. METHODS Patients (6 APOB LOFm and 17 PCSK9 GOFm carriers) with LDL-C ≥70 mg/dL on maximally tolerated lipid-lowering therapies received alirocumab 150 mg at Weeks 0, 2, 4, and 6, placebo at Week 8, alirocumab at Week 10, placebo at Weeks 12 and 14, then completed a follow-up period at Week 22. RESULTS At Week 8, mean ± standard error (SE) alirocumab concentration was lower in APOB LOFm carriers compared with PCSK9 GOFm carriers (12.12 ± 1.81 vs 16.74 ± 2.53 mg/L). APOB LOFm carriers had higher mean ± SE total PCSK9 (6.56 ± 0.73 mg/L) and lower mean ± SE free PCSK9 (0.025 ± 0.016 mg/L) at Week 8 compared with PCSK9 GOFm carriers (4.21 ± 0.35 and 0.11 ± 0.035 mg/L for total and free PCSK9, respectively). Despite this observed greater PCSK9 suppression, mean ± SE percent LDL-C reduction was lower in APOB LOFm (55.3 ± 1.0%) compared with PCSK9 GOFm carriers (73.1 ± 0.9%). Treatment-emergent adverse events occurred in 16 patients (94.1%) in the PCSK9 GOFm group and 5 patients (83.3%) in the APOB LOFm group. CONCLUSIONS Overall, PCSK9 inhibition with alirocumab results in clinically meaningful reductions in LDL-C in both APOB LOFm and PCSK9 GOFm carriers, although reductions were greater in the PCSK9 GOFm carriers. The results indicate a possible underlying contributor to hypercholesterolemia other than PCSK9 in patients with APOB LOFm. CLINICAL TRIAL REGISTRATION NCT01604824; clinicaltrials.gov.

Abstract
In therapeutic trials, the incidence of adverse muscle effects under statin is low, exceptional for some authors,<5% for others. In observational studies, however, this incidence is much higher, up to 20% of patients. These adverse effects are drug-dependent and dose-dependent. It is often complex to distinguish between a real adverse effect and a nocebo effect. Causality is more likely if the symptoms are symmetrical and affect the large muscle masses dependent on the large joints, occur within one month of the introduction of the statin and disappear quickly, within a few weeks after discontinuation of treatment. It seems important not to waste time trying to convince the patient that the alleged muscle symptoms are unrelated to statin therapy. In these patients with suspected statin intolerance, therapeutic impasse is rare and there is a need to attempt dosage reductions, experiment different statins or even prescribe other cholesterol-lowering agents.

Abstract
In the era of precision medicine, treatments that target specific modifiable characteristics of high-risk patients have the potential to lower further the residual risk of atherosclerotic cardiovascular events. Correction of atherogenic dyslipidemia, however, remains a major unmet clinical need. Elevated plasma triglycerides, with or without low levels of high-density lipoprotein cholesterol (HDL-C), offer a key modifiable component of this common dyslipidemia, especially in insulin resistant conditions such as type 2 diabetes mellitus. The development of selective peroxisome proliferator-activated receptor alpha modulators (SPPARMα) offers an approach to address this treatment gap. This Joint Consensus Panel appraised evidence for the first SPPARMα agonist and concluded that this agent represents a novel therapeutic class, distinct from fibrates, based on pharmacological activity, and, importantly, a safe hepatic and renal profile. The ongoing PROMINENT cardiovascular outcomes trial is testing in 10,000 patients with type 2 diabetes mellitus, elevated triglycerides, and low levels of HDL-C whether treatment with this SPPARMα agonist safely reduces residual cardiovascular risk.

Abstract
Cardiovascular diseases are often associated with impaired lipid metabolism. Animal models are useful for deciphering the physiological mechanisms underlying these pathologies. However, lipid metabolism is contrasted between species limiting the transposition of findings from animals to human. Hence, we aimed to compare extended lipid profiles of several animal species to bring new insights in animal model selections. Human lipid phenotype was compared with those of 10 animal species. Standard plasma lipids and lipoprotein profiles were obtained by usual methods and lipidomic analysis was conducted by liquid chromatography-high-resolution mass spectrometry (LC-HRMS). As anticipated, we found contrasted lipid profiles between species. Some of them exhibited similar plasma lipids to human (non-human primate, rat, hamster, pig), but only usual lipid profiles of pigs were superimposable with human. LC-HRMS analyses allowed the identification of 106 other molecular species of lipids, common to all samples and belonging to major lipid families. Multivariate analyses clearly showed that hamster and, in a lower extent mouse, exhibited close lipid fingerprints to that of human. Besides, several lipid candidates that were previously reported to study cardiovascular diseases ranged similarly in human and hamster. Hence, hamster appeared to be the best option to study physiological disturbances related to cardiovascular diseases.

Abstract
BACKGROUND Beyond the hepatobiliary pathway, studies have demonstrated that direct transintestinal cholesterol efflux (TICE) of plasma-derived cholesterol may contribute to reverse cholesterol transport. The clinical evidence of TICE in human remains challenged because of the difficulty to discriminate the hepatobiliary and transintestinal routes in vivo. OBJECTIVE To provide the first proof of concept that TICE exists in vivo in humans by demonstrating that plasma labeled cholesterol can be excreted in the feces of patients with complete bile duct obstruction. METHODS Plasma, bile, and fecal cholesterol excretion was measured by mass spectrometry 24, 48, and 72 hours after intravenous injection of D7-cholesterol in two patients presenting cholangiocarcinomas with a total obstruction of their primary bile duct. RESULTS No trace of bile acids was detected in the feces of the two patients. Despite this, a significant amount of plasma D7-cholesterol was quantified in the feces of the two patients 48 hours and 72 hours after the intravenous injection. CONCLUSION Our data bring a direct proof that TICE is an active pathway in humans.

Abstract
INTRODUCTION Heterozygous familial hypercholesterolemia (FH) is one of the most frequent genetic diseases with a prevalence of 1/250. It is characterized by a very high cholesterol level since birth and is often complicated by cardiovascular diseases (CV) in young patients. While early diagnosis and appropriate therapeutic management can avoid CV complications, HF is largely under-diagnosed and therefore under-treated. METHODS To investigate the management of HF in France, we conducted a survey with 495 general practitioners (n=200) and specialists (n=295). RESULTS The results revealed: a large underestimation of the CV risk and a high therapeutic inertia in the management of the affected patients. The practitioners reported a real need for more information about the disease. CONCLUSION Given the high frequency of HF and the associated cardiovascular morbidity and mortality, general practitioners have a decisive role to play for the identification and the management of these patients. The recent publication of HAS recommendations on family screening procedures and care of HF patients should improve the management of this disease.

Abstract
BACKGROUND The LMF1 (lipase maturation factor 1) gene encodes a protein involved in lipoprotein lipase and hepatic lipase maturation. Homozygous mutations in LMF1 leading to severe hypertriglyceridemia (SHTG) are rare in the literature. A few additional rare LMF1 variants have been described with poor functional studies. OBJECTIVE The aim of this study was to assess the frequency of LMF1 variants in a cohort of 385 patients with SHTG, without homozygous or compound heterozygous deleterious mutations identified in lipoprotein lipase (LPL), apolipoprotein A5 (APOA5), apolipoprotein C2 (APOC2), glycosylphosphatidylinositol-anchored high-density lipoprotein binding protein 1 (GPIHBP1) genes, and to determine their functionality. METHODS LMF1 coding variants were screened using denaturing high-performance liquid chromatography followed by direct sequencing. In silico studies of LMF1 variants were performed, followed by in vitro functional studies using human embryonic kidney 293T (HEK-293T) cells cotransfected with vectors encoding human LPL and LMF1 cDNA. LPL activity was measured in cell culture medium after heparin addition using human VLDL-TG as substrate. RESULTS Nineteen nonsynonymous coding LMF1 variants were identified in 65 patients; 10 variants were newly described in SHTG. In vitro, p.Gly172Arg, p.Arg354Trp, p.Arg364Gln, and p.Arg537Trp LMF1 variants decreased LPL activity, and the p.Trp464Ter variant completely abolished LPL activity. We identified a young girl heterozygote for the p.Trp464Ter variant and a homozygote carrier of the p.Gly172Arg variant with a near 50% decreased LPL activity in vitro and in vivo. CONCLUSION The study confirms the rarity of LMF1 variants in a large cohort of patients with SHTG. LMF1 variants are likely to be involved in multifactorial hyperchylomicronemia. Partial LMF1 defects could be associated with intermittent phenotype as described for p.Gly172Arg homozygous and p.Trp464Ter heterozygous carriers.

Abstract
Human apoE exhibits three major isoforms (apoE2, apoE3, and apoE4) corresponding to polymorphism in the APOE gene. Total plasma apoE concentrations are closely related to these isoforms, but the underlying mechanisms are unknown. We aimed to describe the kinetics of apoE individual isoforms to explore the mechanisms for variable total apoE plasma concentrations. We used LC-MS/MS to discriminate between isoforms by identifying specific peptide sequences in subjects (three E2/E3, three E3/E3, and three E3/E4 phenotypes) who received a primed constant infusion of 2H3-leucine for 14 h. apoE concentrations and leucine enrichments were measured hourly in plasma. Concentrations of apoE2 were higher than apoE3, and concentrations of apoE4 were lower than apoE3. There was no difference between apoE3 and apoE4 catabolic rates and between apoE2 and apoE3 production rates (PRs), but apoE2 catabolic rates and apoE4 PRs were lower. The mechanisms leading to the difference in total plasma apoE concentrations are therefore related to contrasted kinetics of the isoforms. Production or catabolic rates are differently affected according to the specific isoforms. On these grounds, studies on the regulation of the involved biochemical pathways and the impact of pathological environments are now warranted.

MELOE-1 and MELOE-2, two highly specific melanoma antigens involved in T cell immunosurveillance are produced by IRES-dependent translation of the long « non coding » and polycistronic RNA, meloe. In the present study, we document the expression of an additional ORF, MELOE-3, located in the 5' region of meloe. Data from in vitro translation experiments and transfection of melanoma cells with bicistronic vectors documented that MELOE-3 is exclusively translated by the classical cap-dependent pathway. Using a sensitive tandem mass spectrometry technique, we detected the presence of MELOE-3 in total lysates of both melanoma cells and normal melanocytes. This contrasts with our previous observation of the melanoma-restricted expression of MELOE-1 and MELOE-2. Furthermore, in vitro stimulation of PBMC from 6 healthy donors with overlapping peptides from MELOE-1 or MELOE-3 revealed a very scarce MELOE-3 specific T cell repertoire as compared to the abundant repertoire observed against MELOE-1. The poor immunogenicity of MELOE-3 and its expression in melanocytes is consistent with an immune tolerance towards a physiologically expressed protein. In contrast, melanoma-restricted expression of IRES-dependent MELOE-1 may explain its high immunogenicity. In conclusion, within the MELOE family, IRES-dependent antigens represent the best T cell targets for immunotherapy of melanoma.

Abstract
OBJECTIVE ApoM (apolipoprotein M) binds primarily to high-density lipoprotein before to be exchanged with apoB (apolipoprotein B)-containing lipoproteins. Low-density lipoprotein (LDL) receptor-mediated clearance of apoB-containing particles could influence plasma apoM kinetics and decrease its antiatherogenic properties. In humans, we aimed to describe the interaction of apoM kinetics with other components of lipid metabolism to better define its potential benefit on atherosclerosis. APPROACH AND RESULTS Fourteen male subjects received a primed infusion of 2H3-leucine for 14 hours, and analyses were performed by liquid chromatography-tandem mass spectrometry from the hourly plasma samples. Fractional catabolic rates and production rates within lipoproteins were calculated using compartmental models. ApoM was found not only in high-density lipoprotein (59%) and LDL (4%) but also in a non-lipoprotein-related compartment (37%). The apoM distribution was heterogeneous within LDL and non-lipoprotein-related compartments according to plasma triglycerides (r=0.86; P<0.001). The relationships between sphingosine-1-phosphate and apoM were confirmed in all compartments (r range, 0.55-0.89; P<0.05). ApoM fractional catabolic rates and production rates were 0.16±0.07 pool/d and 0.14±0.06 mg/kg per day in high-density lipoprotein and 0.56±0.10 pool/d and 0.03±0.01 mg/kg per day in LDL, respectively. Fractional catabolic rates of LDL-apoM and LDL-apoB100 were correlated (r=0.55; P=0.042). Significant correlations were found between triglycerides and production rates of LDL-apoM (r=0.73; P<0.004). CONCLUSIONS In humans, LDL kinetics play a key role in apoM turnover. Plasma triglycerides act on both apoM and sphingosine-1-phosphate distributions between lipoproteins. These results confirmed that apoM could be bound to high-density lipoprotein after secretion and then quickly exchanged with a non-lipoprotein-related compartment and to LDL to be slowly catabolized.

Abstract
OBJECTIVE Bariatric surgery appears as the most efficient therapeutic alternative in morbidly obese patients. In addition to its efficiency to decrease body weight, it also improves metabolic complications associated to morbid obesity, including dyslipidemia. Although the cholesterol-lowering effect varies with the bariatric procedures, the underlying molecular mechanisms remain poorly defined. This study aims to assess the consequence of both restrictive (sleeve gastrectomy; SG) and malabsorptive (Roux-en-Y gastric bypass; RYGB) procedures on cholesterol metabolism in mice. SUBJECTS Ten-week-old C57BL6/J males were fed with a high-fat diet for 8-14 weeks before sleeve or RYGB surgery. RESULTS SG has a modest and transient effect on plasma cholesterol levels, linked to a reduction in food intake. In contrast, modified RYGB led to a sustained ≈35% reduction in plasma cholesterol concentrations with a drastic increase in fecal cholesterol output. Mechanistically, RYGB exerts a synergystic effect on cholesterol metabolism by inducing the trans-intestinal cholesterol efflux and reducing the intestinal cholesterol absorption. CONCLUSIONS In mice, RYGB, but not sleeve, strongly favors plasma cholesterol elimination by concomitantly increasing trans-intestinal cholesterol excretion and by decreasing intestinal cholesterol absorption. Our models open new perspective for deciphering the hypocholesterolemic effects of bariatric procedures.

Abstract
OBJECTIVE Experimental studies suggest that maternal hypercholesterolemia may be relevant for the early onset of cardiovascular disease in offspring. We investigated the effect of perinatal hypercholesterolemia on the atherosclerosis development in the offspring of apolipoprotein E-deficient mice and the underlying mechanism. APPROACH AND RESULTS Atherosclerosis and related parameters were studied in adult male or female apolipoprotein E-deficient mice offspring from either normocholesterolemic or hypercholesterolemic mothers and normocholesterolemic fathers. Female born to hypercholesterolemic mothers had more aortic root lesions than female born to normocholesterolemic mothers. Lesions in whole aorta did not differ between groups. Higher trimethylamine-N-oxide levels and Fmo3 hepatic gene expression were higher in female born to hypercholesterolemic mothers offspring compared with female born to normocholesterolemic mothers and male. Trimethylamine-N-oxide levels were correlated with the size of atherosclerotic root lesions. Levels of hepatic cholesterol and gallbladder bile acid were greater in male born to hypercholesterolemic mothers compared with male born to normocholesterolemic mothers. At 18 weeks of age, female born to hypercholesterolemic mothers showed lower hepatic Scarb1 and Cyp7a1 but higher Nr1h4 gene expression compared with female born to normocholesterolemic mothers. Male born to hypercholesterolemic mothers showed an increase in Scarb1 and Ldlr gene expression compared with male born to normocholesterolemic mothers. At 25 weeks of age, female born to hypercholesterolemic mothers had lower Cyp7a1 gene expression compared with female born to normocholesterolemic mothers. DNA methylation of Fmo3, Scarb1, and Ldlr promoter regions was slightly modified and may explain the mRNA expression modulation. CONCLUSIONS Our findings suggest that maternal hypercholesterolemia may exacerbate the development of atherosclerosis in female offspring by affecting metabolism of trimethylamine-N-oxide and bile acids. These data could be explained by epigenetic alterations.

Abstract
This report describes a problem-based learning activity concerning antibiotic exposure and bacterial resistance in human and veterinary medicine. In addition, learning outcomes and satisfaction of students were recorded by the supervisors of the activity. The students all participated actively in the group work and considered that the small size of the group facilitated interpersonal communication. They believed that working in an interdisciplinary group helped them learn better than if they were following specific courses. They also reported that their mid-term meeting with one of the supervisors was a catalyst for the initiation of a real work group. Concerning the evaluation of the activity itself, the supervisors considered that the group provided a relevant analysis of the issue. These characteristics should encourage teachers to test this method of learning certain aspects of microbiology and infectious diseases with their students.
