    (2020) ALVES, Ana Catarina; ALONSO, Rodrigo; DIAZ-DIAZ, Jose Luis; MEDEIROS, Ana Margarida; JANNES, Cinthia E.; MERCHAN, Alonso; VASQUES-CARDENAS, Norma A.; CUEVAS, Ada; CHACRA, Ana Paula; KRIEGER, Jose E.; ARROYO, Raquel; ARRIETA, Francisco; SCHREIER, Laura; CORRAL, Pablo; BANARES, Virginia G.; ARAUJO, Maria B.; BUSTOS, Paula; ASENJO, Sylvia; STOLL, Mario; DELL'OCA, Nicolas; REYES, Maria; RESSIA, Andres; CAMPO, Rafael; MAGANA-TORRES, Maria T.; METHA, Roopa; AGUILAR-SALINAS, Carlos A.; CEBALLOS-MACIAS, Jose J.; MORALES, Alvaro J. Ruiz; MATA, Pedro; BOURBON, Mafalda; SANTOS, Raul D.
    Objective: Characterize homozygous familial hypercholesterolemia (HoFH) individuals from Iberoamerica. Approach and Results: In a cross-sectional retrospective evaluation 134 individuals with a HoFH phenotype, 71 adults (age 39.3 +/- 15.8 years, 38.0% males), and 63 children (age 8.8 +/- 4.0 years, 50.8% males) were studied. Genetic characterization was available in 129 (96%). The majority (91%) were true homozygotes (true HoFH, n=79, 43.0% children, 46.8% males) or compound heterozygotes (compound heterozygous familial hypercholesterolemia, n=39, 51.3% children, 46.2% males) with putative pathogenic variants in theLDLR. True HoFH due toLDLRvariants had higher total (P=0.015) and LDL (low-density lipoprotein)-cholesterol (P=0.008) compared with compound heterozygous familial hypercholesterolemia. Children with true HoFH (n=34) tended to be diagnosed earlier (P=0.051) and had a greater frequency of xanthomas (P=0.016) than those with compound heterozygous familial hypercholesterolemia (n=20). Previous major cardiovascular events were present in 25 (48%) of 52 children (missing information in 2 cases), and in 43 (67%) of 64 adults withLDLRvariants. Children who are true HoFH had higher frequency of major cardiovascular events (P=0.02), coronary heart (P=0.013), and aortic/supra-aortic valve diseases (P=0.022) than compound heterozygous familial hypercholesterolemia. In adults, no differences were observed in major cardiovascular events according to type ofLDLRvariant. From 118 subjects withLDLRvariants, 76 (64%) had 2 likely pathogenic or pathogenic variants. In 89 subjects with 2LDLRvariants, those with at least one null allele were younger (P=0.003) and had a greater frequency of major cardiovascular events (P=0.038) occurring at an earlier age (P=0.001). Conclusions: There was a high frequency of cardiovascular disease even in children. Phenotype and cardiovascular complications were heterogeneous and associated with the type of molecular defect.

    Screening of ABCG5 and ABCG8 Genes for Sitosterolemia in a Familial Hypercholesterolemia Cascade Screening Program
    (2022) TADA, Mauricio Teruo; ROCHA, Viviane Zorzanelli; LIMA, Isabella Ramos; OLIVEIRA, Theo Gremen Mimary; CHACRA, Ana Paula; MINAME, Marcio Hiroshi; NUNES, Valeria Sutti; NAKANDAKARE, Edna Regina; CASTELO, Maria Helane Costa Gurgel; JANNES, Cinthia Elim; SANTOS, Raul D.; KRIEGER, Jose Eduardo; PEREIRA, Alexandre Costa
    Background: Sitosterolemia is a rare autosomal recessive disorder caused by homozygous or compound heterozygous variants in ABCG5/ABCG8. The disease is characterized by increased plasma plant sterols. Small case series suggest that patients with sitosterolemia have wide phenotypic heterogeneity with great variability on either plasma cholesterol levels or development of atherosclerotic cardiovascular disease. The present study aims to characterize the prevalence and clinical features of sitosterolemia participating in a familial hypercholesterolemia genetic cascade screening program. Methods: From 443 familial hypercholesterolemia index cases, 260 were negative for familial hypercholesterolemia genes and were sequenced for the ABCG5/8 genes. Clinical and laboratory characteristics of affected individuals were determined. Results: Eight (3.1%) index cases were found to be homozygous or compound heterozygous variant for ABCG5/ABCG8 genes, confirming the genetic diagnosis of sitosterolemia. Screening their relatives led to the identification of 6 additional confirmed sitosterolemia cases (3 homozygous and 3 compound heterozygous variant) and 18 carriers (heterozygous). The mean age of identified sitosterolemia cases (n=14) was 37.2 +/- 19.8 years, 50% were females, and 78.6% (all adults) presented either clinical or subclinical atherosclerotic cardiovascular disease. As expected, affected individuals presented elevated plasma plant sterol levels (mean beta-Sitosterol and campesterol, respectively, 160.3 +/- 107.1 and 32.0 +/- 19.6 mu g/mL) and the highest plasma LDL (low-density lipoprotein)-cholesterol was 269.0 +/- 120.0 mg/dL (range: 122-521 mg/dL). LDL-cholesterol mean reduction with therapy among cases was 65%. Eighty-three percent (83%) of identified sitosterolemia patients presented hematologic abnormalities. Conclusions: Testing genes associated with sitosterolemia in the molecular routine workflow of a familial hypercholesterolemia cascade screening program allowed the precise diagnosis of sitosterolemia in a substantial number of patients with varying LDL-C levels and high incidence of early atherosclerotic cardiovascular disease and hematologic abnormalities.

    Cardiovascular disease onset in old people with severe hypercholesterolemia
    (2023) COUTINHO, Elaine R.; MINAME, Marcio H.; ROCHA, Viviane Z.; BITTENCOURT, Marcio S.; JANNES, Cinthia E.; KRIEGER, Jose E.; PEREIRA, Alexandre C.; SANTOS, Raul D.
    Background and aims: Familial hypercholesterolemia (FH) variants are associated with higher atherosclerotic cardiovascular disease risk (ASCVD) even when compared with other forms of severe hypercholesterolemia, especially in young people. Lipid lowering therapies (LLT) may change hypercholesterolemia natural history. This study aimed at evaluating factors associated with occurrence of ASCVD in old severe hypercholesterolemics diagnosed or not with FH and undergoing LLT.Methods: Hypercholesterolemic individuals >= 60 years participating on a genetic cascade screening for FH were divided in 4 groups (2 x 2) according to the presence (variant+) or not (variant-) of FH genetic variants and previous ASCVD (ASCVD+ and ASCVD-). Biomarkers associated with new incident ASCVD events were tested using Cox models. Continuous data shown as medians (%25; %75).Results: From 4,111 genotyped individuals, 377 (9.1%) were elderly [age 66 (63; 71) years], 28.9% males, 42.7% variant+, 32.1% with previous ASCVD, LLT duration 9 (5; 16) years, and on treatment LDL-cholesterol 144 (109; 200) mg/dL. After 4.8 (7; 3) years of follow up there were 47 incident events (12.4%, 2.7% patient/year). The annualized event rates were 0.8% (95% CI 0.36%; 1.70%), 2.3% (95% CI 1.3%; 4.1%), 5.2% (95% CI 2.8%; 9.7%) and 6.3% (95% CI 4.0%; 10.0%) respectively for groups variant-/ASCVD-, variant+/ASCVD-, variant-/ ASCVD+ and, variant+/ASCVD+ (p log rank p < 0.001). Only presence of previous ASCVD was independently associated with incident ASCVD [hazard ratio 3.236 (95%CI 1.497-6.993, p = 0.003)]. No interaction was found for previous ASCVD and variants.Conclusions: In old severe hypercholesterolemic individuals undergoing long-term LLT previous ASCVD was associated with incident events while FH causing variants were not.

    Vascular age derived from coronary artery calcium score on the risk stratification of individuals with heterozygous familial hypercholesterolaemia
    (2020) MINAME, Marcio H.; BITTENCOURT, Marcio Sommers; PEREIRA, Alexandre C.; JANNES, Cinthia E.; KRIEGER, Jose E.; NASIR, Khurram; SANTOS, Raul D.
    Aims The objective of this study was to evaluate if vascular age derived from coronary artery calcium (CAC) score improves atherosclerosis cardiovascular disease (ASCVD) risk discrimination in primary prevention asymptomatic heterozygous familial hypercholesterolaemia (FH) patients undergoing standard lipid-lowering therapy. Methods and results Two hundred and six molecularly confirmed FH individuals (age 45 +/- 14 years, 36% males, baseline LDL-cholesterol 6.2 +/- 2.2 mmol/L; 239 +/- 85mg/dL) were followed by 4.4 +/- 2.9 years (median: 3.7 years, interquartile ranges 2.7-6.8). CAC measurement was performed, and lipid-lowering therapy was optimized according to FH guidelines. Vascular age was derived from CAC and calculated according to the Multi Ethnic Study of Atherosclerosis algorithm. Risk estimation based on the Framingham equations was calculated for both biological (bFRS) and vascular (vaFRS) age. During follow-up, 15 ASCVD events (7.2%) were documented. The annualized rate of events for bFRS <10%, 10-20%, and >20% was respectively: 8.45 [95% confidence interval (CI) 3.17-22.52], 23.28 (95% CI 9.69-55.94), and 28.13 (95% CI 12.63-62.61) per 1000 patients. The annualized rate of events for vaFRS <10%, 10-20%, and >20% was respectively: 0, 0, and 50.37 (95% CI 30.37-83.56) per 1000 patients. vaFRS presented a better discrimination for ASCVD events compared to bFRS 0.7058 (95% CI 0.5866-0.8250) vs. vaFRS 0.8820 (95% CI 0.8286-0.9355), P= 0.0005. Conclusion CAC derived vascular age can improve ASCVD risk discrimination in primary prevention FH subjects. This tool may help further stratify risk in FH patients already receiving lipid-lowering medication who might be candidates for further treatment with newer therapies.

    Predictors of cardiovascular events after one year of molecular screening for Familial hypercholesterolemia
    (2016) SILVA, Pamela R. S.; JANNES, Cinthia E.; MARSIGLIA, Julia D. C.; KRIEGER, Jose E.; SANTOS, Raul D.; PEREIRA, Alexandre C.
    Background and aims: This study reports the first year follow-up of individuals enrolled in Brazil's genetic cascade screening program for Familial Hypercholesterolemia (FH), Hipercol Brasil. Predictors for the occurrence of cardiovascular (CV) events in individuals screened for FH were studied. Methods: This is an open prospective cohort of individuals who were included in a cascade genetic screening program for FH. The first prospective follow-up was carried out one year after patients received their genetic test result. Individuals included in this study were index cases (probands) and relatives with identified (M+) or not genetic mutations (M-). Logistic regression analysis was performed to determine predictive variables for the occurrence of CV events censored at one-year of follow-up. Results: A total of 818 subjects were included, 47 first CV events were ascertained, with 14 (29.7%) being fatal. For index cases, the only factor independently associated with increased risk of CV events was the presence of corneal arcus (OR: 9.39; 95% CI: 2.46-35.82). There was an inverse association of CV events with higher HDL-cholesterol levels (OR: 0.95; 95% CI: 0.90-0.99). For M+ relatives, risk factors associated with increased CV events risk were diabetes mellitus (OR: 7.97; 95% CI: 2.07-30.66) and tobacco consumption (OR: 3.70; 95% CI: 1.09-12.50). Conclusions: A high one-year incidence of CV events was found in this cascade-screening cohort. Predictors of events differed between index cases and relatives and can be useful for the development of preventive efforts in this highly susceptible group of individuals.

    Peripheral arterial disease in heterozygous familial hypercholesterolemia
    (2015) PEREIRA, Carolina; MINAME, Marcio H.; MAKDISSE, Marcia R. P.; WATANABE, Carolina; PESARO, Antonio E.; JANNES, Cinthia E.; KALIL FILHO, Roberto; PEREIRA, Alexandre C.; SANTOS, Raul D.
    Background: Familial hypercholesterolemia is characterized by elevated plasma cholesterol and early coronary arterial disease onset. However, few studies investigated the association of heterozygous familial hypercholesterolemia with peripheral arterial disease. Methods: In a cross sectional study 202 heterozygous familial hypercholesterolemia patients (91% confirmed by molecular diagnosis) were compared to 524 normolipidemic controls. Peripheral arterial disease was diagnosed by ankle-brachial index values <= 0.90. Results: Compared with controls, familial hypercholesterolemia patients were older, more often female, with higher rates of hypertension, diabetes, previous coronary disease and higher total cholesterol levels. Smoking (previous and former) was more common among controls. The prevalence of peripheral arterial disease was 17.3 and 2.3% respectively in familial hypercholesterolemia and controls (p < 0.001). Results persisted after matching familial hypercholesterolemia and controls by a propensity score. Regression analyses demonstrated that age (odds ratio-OR = 1.03 95% CI 1.00-1.05, p = 0.033), previous cardiovascular disease (OR = 3.12 CI 95% 1.56-6.25, p = 0.001) and familial hypercholesterolemia diagnosis (OR = 5.55 CI 95% 2.69-11.44, p < 0.001) were independently associated with peripheral arterial disease. Among familial hypercholesterolemia patients, age (OR 1.05, 95% CI 1.02-1.09, p = 0.005), intermittent claudication (OR 6.32, 95% CI 2.60-15.33, p < 0.001) and smoking (OR 2.44, 95% CI 1.08-5.52, p = 0.032) were associated with peripheral arterial disease. Conclusions: Peripheral arterial disease is more frequent in familial hypercholesterolemia than in normolipidemic subjects and it should routine screened in these individuals even if asymptomatic. However, its role as predictor of cardiovascular events needs to be ascertained prospectively.

    Coronary Artery Calcium and Cardiovascular Events in Patients With Familial Hypercholesterolemia Receiving Standard Lipid-Lowering Therapy
    (2019) MINAME, Marcio H.; BITTENCOURT, Marcio Sommer; MORAES, Sergio R.; ALVES, Romulo I. M.; SILVA, Pamela R. S.; JANNES, Cinthia E.; PEREIRA, Alexandre C.; KRIEGER, Jose E.; NASIR, Khurram; SANTOS, Raul D.
    OBJECTIVES The aim of this study was to evaluate the role of coronary artery calcium (CAC) as a predictor of atherosclerotic cardiovascular disease (ASCVD) (fatal or not myocardial infarction, stroke, unstable angina requiring revascularization, and elective myocardial revascularization) events in asymptomatic primary prevention molecularly proven heterozygous familial hypercholesterolemia (FH) subjects receiving standard lipid-lowering therapy. BACKGROUND FH is associated with premature ASCVD. However, the clinical course of ASCVD in subjects with FH is heterogeneous. CAC score, a marker of subclinical atherosclerosis burden, may optimize ASCVD risk stratification in FH. METHODS Subjects with FH underwent CAC measurement and were followed prospectively. The association of CAC with ASCVD was evaluated using multivariate analysis. RESULTS A total of 206 subjects (mean age 45 +/- 14 years, 36.4% men, baseline and on-treatment low-density lipoprotein cholesterol 269 +/- 70 mg/dl and 150 +/- 56 mg/dl, respectively) were followed for a median of 3.7 years (interquartile range: 2.7 to 6.8 years). CAC was present in 105 (51%), and 15 ASCVD events (7.2%) were documented. Almost one-half of events were hard outcomes, and the others were elective myocardial revascularizations. The annualized rates of events per 1,000 patients for CAC scores of 0 (n = 101 [49%]), 1 to 100 (n = 62 [30%]) and >100 (n = 43 [21%]) were, respectively, 0, 26.4 (95% confidence interval: 12.9 to 51.8), and 44.1 (95% confidence interval, 26.0 to 104.1). In multivariate Cox regression analysis, log(CAC score 1) was independently associated with incident ASCVD events (hazard ratio: 3.33; 95% CI: 1.635 to 6.790; p = 0.001). CONCLUSIONS CAC was independently associated with ASCVD events in patients with FH receiving standard lipid-lowering therapy. This may help further stratify near-term risk in patients who might be candidates for further treatment with newer therapies. (C) 2019 by the American College of Cardiology Foundation.

    Familial hypercholesterolemia and cardiovascular disease in older individuals
    (2021) COUTINHO, Elaine R.; MINAME, Marcio H.; ROCHA, Viviane Z.; BITTENCOURT, Marcio S.; JANNES, Cinthia E.; TADA, Mauricio T.; LIMA, Isabella R.; SALGADO FILHO, Wilson; CHACRA, Ana P.; PEREIRA, Alexandre C.; KRIEGER, Jose E.; SANTOS, Raul D.
    Background and aims: Familial hypercholestemlemia (FH) is characterized by high LDL-cholesterol (LDL-C) and early atherosclerotic cardiovascular disease (ASCVD). With a lipid lowering therapy (LLT), most individuals with FH may have a longer ASCVD-free survival. However, there is scant data about older individuals with FH. Methods: We compared characteristics of genetically defined FH older individuals with age-matched non-FH counterparts. Results: From 4111 genotyped individuals, 462 older than 60 years were included (198 positive and 264 negative for FH variants). There were no differences regarding median age [%25; 75%] 66.0 (62.0; 71.0) and 66.0 (62.2; 71.0) years, p = 0.68 for FH and non-FH, respectively. In both groups, there was a higher frequency of females, however, there were more males in the FH group 37.4% vs. 24.2%, p = 0.002. No differences were seen between FH and non-FH in LLT use: 88.5% vs. 91.5%, p = 0.29. Despite a longer LLT duration in FH patients (with 11.0 (7.0; 20.0) vs. 7.0 (3.0; 13.0) years, p < 0.001), treatment was started late in both groups: at 54.0 (47.0; 61.0) and 59.0 (52.0; 64.0) years, p < 0.001, in FH and non-FH, respectively. FH had greater frequencies of previous and early ASCVD (40.9% vs. 27.3%, p = 0.002, and 22.2% vs. 9.0%, p < 0.001). In FH, male sex [HR (95%C01 2.67 (1.50-4.73), p = 0.001, and LLT onset age 0.96 (0.93-0.99), p = 0.009, were independently associated with ASCVD. Conclusions: Among hypercholesterolemic older individuals participating in a cascade screening program, the genetic diagnosis of FH was associated with higher ASCVD rates, emphasizing the relevance of a monogenic defect as the cause of long-lasting hypercholesterolemia and ASCVD risk, particularly in men.
