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.

"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.

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.

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%).

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.
