Familial hypercholesterolaemia: A global call to arms
2015
Familial Hypercholesterolaemia (FH) is the commonest autosomal co-dominantly inherited condition affecting man. It is caused by mutation in one of three genes, encoding the low-density lipoprotein (LDL) receptor, or the gene for apolipoprotein B (which is the major protein component of the LDL particle), or in the gene coding for PCSK9 (which is involved in the degradation of the LDL-receptor during its cellular recycling). These mutations result in impaired LDL metabolism, leading to life-long elevations in LDL-cholesterol (LDL-C) and development of premature atherosclerotic cardiovascular disease (ASCVD) [1], [2] and [3]. If left untreated, the relative risk of premature coronary artery d…
Lack of phenotypic additive effect of familial defective apolipoprotein B3531 in familial hypercholesterolaemia.
2020
Familial defective apolipoprotein (apo) B (FDB) and familial hypercholesterolaemia (FH) are the two common genetic conditions that cause hypercholesterolaemia. R3531C mutation of the APOB gene is a rare cause of FDB. Individuals with both FDB and FH are rare. A 51-year-old man with hypercholesterolaemia (11.4 mmol/L) and his family were studied. Low-density lipoprotein (LDL) receptor (LDLR) and APOB genes were analysed by direct sequencing. LDL of four subjects were studied in a fibroblast LDL receptor-binding displacement assay. We found a mutation of the LDLR gene (p.Y398X) in the proband and in four other family members: the p.R3531C APOB gene mutation was also found in the proband, his …
Long-term hepatic safety of lomitapide in homozygous familial hypercholesterolaemia
2023
Introduction: Lomitapide is a microsomal triglyceride transfer protein inhibitor for patients with homozygous familial hypercholesterolaemia. Due to its mechanism of action, potential hepatic effects of lomitapide are of clinical interest. This study aimed to determine the long-term hepatic safety of lomitapide. Methods: Data were aggregated from the pivotal phase 3 and extension phase clinical trial with lomitapide (median 5.1 years; serum total bilirubin, transaminases, cytokeratin-18 [CK-18] and enhanced liver fibrosis [ELF] score, fat-soluble vitamins and essential fatty acids), 8-year data from the Lomitapide Observational Worldwide Evaluation Registry (LOWER) and real-world evidence f…
Nelipīdu riska faktoru izvērtējums pacientiem ar ģimenes hiperholesterolēmiju
2018
Pamatojums: Ģimenes Hiperholesterinēmija (ĢH) raksturojas ar paaugstinātu zema blīvuma lipoproteīnu holesterīna (ZBL-H) koncentrāciju, kas ievērojami paaugstina agrīnu kardiovaskulāro slimību (KVS) attīstības risku. Papildus (ZBL-H) citu, ar lipīdiem nesaistītu, riska faktoru nozīmīgai ietekmei uz KVS attīstības risku, ir svarīga to identifikācija un kontrole jau dzīves laikā vai kopš bērnības. Mērķis: Raksturot un identificēt biežākos ar lipīdiem nesaistītus riska faktorus, kas var veicināt KVS attīstību pacientiem ar ĢH, kas tādējādi varētu palīdzēt akcentēt nozīmi to turpmākai kontrolei. Materiāli un metodes: Šī ir retrospektīva kohorta analīze pacientu grupai ar ticamu vai drošu ĢH diag…
Hipercolesterolemia familiar homocigota: adaptación a España del documento de posición del grupo de consenso sobre hipercolesterolemia familiar de la…
2015
Homozygous familial hypercholesterolaemia (HoFH) is a rare life-threatening disease characterized by markedly elevated circulating levels of low-density lipoprotein cholesterol (LDL-C) and accelerated, premature atherosclerotic cardiovascular disease (ACVD). The Consensus Panel on Familial Hypercholesterolaemia of the European Atherosclerosis Society (EAS) has recently published a clinical guide to diagnose and manage HoFH (Eur Heart J. 2014;35:2146-57). Both the Spanish Society of Atherosclerosis (SEA) and Familial Hypercholesterolaemia Foundation (FHF) consider this European Consensus document of great value and utility. However, there are particularities in our country which advise to ha…
Genetically determined hypercholesterolaemia results into premature leucocyte telomere length shortening and reduced haematopoietic precursors
2020
Abstract Aims Leucocyte telomere length (LTL) shortening is a marker of cellular senescence and associates with increased risk of cardiovascular disease (CVD). A number of cardiovascular risk factors affect LTL, but the correlation between elevated LDL cholesterol (LDL-C) and shorter LTL is debated: in small cohorts including subjects with a clinical diagnosis of familial hypercholesterolaemia (FH). We assessed the relationship between LDL-C and LTL in subjects with genetic familial hypercholesterolaemia (HeFH) compared to those with clinically diagnosed, but not genetically confirmed FH (CD-FH), and normocholesterolaemic subjects. Methods and results LTL was measured in mononuclear cells-d…
