conferenceObject PREDICTORS OF CORONARY ARTERY CALCIFICATION INCIDENCE IN SEVERE HYPERCHOLESTEROLEMIA(2023) MARTE, Ana; MINAME, Marcio Hiroshi; PARDI, Estevao Magalhaes; GANEM, Lucas; MIZUTA, Marjorie Hayashida; ROCHA, Viviane Zorzanelli; PEREIRA, Alexandre Costa; KRIEGER, Jose Eduardo; SANTOS, Raul- 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 CostaBackground: 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.
- Achilles tendon xanthomas are associated with the presence and burden of subclinical coronary atherosclerosis in heterozygous familial hypercholesterolemia: A pilot study(2017) MANGILI, Leonardo C.; MINAME, Marcio H.; SILVA, Pamela R. S.; BITTENCOURT, Marcio S.; ROCHA, Viviane Z.; MANGILI, Otavio C.; SALGADO FILHO, Wilson; CHACRA, Ana P.; JANNES, Cinthia E.; PEREIRA, Alexandre C.; SANTOS, Raul D.Background and aims: Achilles tendon xanthomas (ATX) are a sign of long-term exposure to high blood cholesterol in familial hypercholesterolemia (FH) patients, which have been associated with cardiovascular disease. We evaluated the ATX association with the presence and extent of subclinical coronary atherosclerosis in heterozygous FH patients. Methods: 102 FH patients diagnosed by US-MEDPED criteria (67% with genetically proven FH), with median LDL-C 279 mg/dL (interquartile range: 240; 313), asymptomatic for cardiovascular disease, underwent computed tomography angiography and coronary artery calcium (CAC) quantification. Subclinical coronary atherosclerosis was quantified by CAC, segment-stenosis (SSS) and segment-involvement (SIS) scores. Adjusted Poisson regression was used to assess the association of ATX with subclinical atherosclerosis burden as continuous variables. Results: Patients with ATX (n = 21, 21%) had higher LDL-C and lipoprotein(a) [Lp(a)] concentrations as well as greater CAC scores, SIS and SSS (p < 0.05). After adjusting for age, sex, smoking, hypertension, previous statin use, HDL-C, LDL-C and Lp(a) concentrations, there was an independent positive association of ATX presence with CAC scores (beta = 1.017, p < 0.001), SSS (beta = 0.809, p < 0.001) and SIS (beta = 0.640, p < 0.001). Conclusions: ATX are independently associated with the extension of subclinical coronary atherosclerosis quantified by tomographic scores in FH patients.
