Pediatrics cascade screening in inherited dyslipidemias: a lipoprotein apheresis center experience.

Familial hypercholesterolemia (FH) is less rare than one might think and, despite highly effective lipid-lowering therapies (LLT), more than half of the patients treated do not reach the lipid target indicated by the guidelines. In these patients, lipoprotein apheresis (LA) is the most effective tool to lowering apo-B containing atherogenic lipoproteins. In own center, since 1994, thanks to routinely cascade testing performed in patients who start LA, we have identified a pediatric population (30 subjects) that we analyzed retrospectively.

Widespread xanthomas regression by personalized lipid lowering therapy in heterozygous familial hypercholesterolemia.

"The lower, the better" is the recommended approach in the management of high LDL cholesterol. Unfortunately, this does not always achieve as in the case of a 69-year-old woman referred to our Institute for her lipid profile (LDL cholesterol 412mg/dl), bilateral xanthelasma and cutaneous xanthomas. With a maximized and personalized lipid-lowering therapies (rosuvastatin, ezetimibe, PCSK9i and lipoprotein apheresis), after only six months, the patient showed an impressive regression in her cutaneous xanthomas.

PCSK9 and leptin plasma levels in anorexia nervosa.

Aim: Proprotein convertase subtilisin/kexin type 9 (PCSK9) is a regulator of low-density-lipoprotein cholesterol (LDL-C), a major risk factor for cardiovascular (CV) disease. Since the hormone leptin has been suggested as having a role in CV risk regulation, possibly by modulating LDL receptor expression through the PCSK9 pathway, nutritional status may represent a potential regulator. Thus, evaluation of PCSK9 levels in human eating disorders appears to be of interest.

Comorbidity in lipoprotein apheresis: Their role in the era of new lipid-lowering therapies.

Background: Despite advance in pharmacotherapy of lipid disorders, lipoprotein apheresis (LA) plays a leading role in the management of severe hypercholesterolemia and in atherosclerosis prevention.

Methods: Aim of this study was to retrospectively evaluate Charlson Comorbidity Index (CCI), presence of major comorbidity, and/or concomitant polypharmacy (definite as 5+ drugs daily) in patients with inherited dyslipidemias on chronic LA.

Results: Since 1994, we performed more than 500 LA treatment/year and followed a total of 83 patients (age 56 [47-65] years, male 75%).

Major cardiovascular events increase in long-term proprotein convertase subtilisin/kexin type 9 inhibitors therapy: the Tuscany cost-effective study.

Background: Proprotein convertase subtilisin/kexin type 9 inhibitors (PCSK9i) represent a breakthrough in the treatment of hypercholesterolemia. The aim of this study was to perform a multicentre prospective analysis on the effects of PCSK9i since their distribution in Italy.

Methods: During the study period (July 2017 to February 2022) 246 patients (mean age 61 ± 11 years, male 73%) who were evolocumab (142/246) or alirocumab (104/246) new users were enrolled in the CERTI (Costo Efficacia Regione Toscana Inibitori PCSK9) study.

Consensus document on Lipoprotein(a) from the Italian Society for the Study of Atherosclerosis (SISA).

Aims: In view of the consolidating evidence on the causal role of Lp(a) in cardiovascular disease, the Italian Society for the Study of Atherosclerosis (SISA) has assembled a consensus on Lp(a) genetics and epidemiology, together with recommendations for its measurement and current and emerging therapeutic approaches to reduce its plasma levels. Data on the Italian population are also provided.

Data Synthesis: Lp(a) is constituted by one apo(a) molecule and a lipoprotein closely resembling to a low-density lipoprotein (LDL).

Acute Increase in Ocular Microcirculation Blood Flow Upon Cholesterol Removal. The Eyes Are the Window of the Heart.

Background: Lipoprotein apheresis acutely increases coronary microvascular blood flow. However, measurement techniques are time-consuming, costly, and invasive. The ocular vasculature may be an appropriate surrogate and an easily accessible window to investigate the microcirculation.

Triglycerides and low HDL cholesterol predict coronary heart disease risk in patients with stable angina.

We assessed whether high triglycerides (TG) and low high-density lipoprotein cholesterol (HDL-C) levels, expressed by an increased TG/HDL-C ratio, predict coronary atherosclerotic disease (CAD) outcomes in patients with stable angina. We studied 355 patients (60 ± 9 years, 211 males) with stable angina who underwent coronary computed tomography angiography (CTA), were managed clinically and followed for 4.5 ± 0.

Gender difference in lipoprotein(a) concentration as a predictor of coronary revascularization in patients with known coronary artery disease.

Background And Aims: Whether there is a gender difference in the impact of elevated plasma Lp(a) levels on recurrent coronary events remains unclear. We, therefore, evaluated the association between Lp(a) levels and the occurrence of major adverse coronary events in a large series of coronary patients (32% women).

Methods: This single-center prospective cohort study investigated 3034 consecutive patients admitted to the Coronary Care Unit with a diagnosis of coronary ischemia.

Progression of chronic kidney disease in familial LCAT deficiency: a follow-up of the Italian cohort.

Familial LCAT deficiency (FLD) is a rare genetic disorder of HDL metabolism, caused by loss-of-function mutations in the gene and characterized by a variety of symptoms including corneal opacities and kidney failure. Renal disease represents the leading cause of morbidity and mortality in FLD cases. However, the prognosis is not known and the rate of deterioration of kidney function is variable and unpredictable from patient to patient.
