Abstract

We present a clinical case of a patient with familial hypercholesterolemia (FH), a marked increase in low-density lipoprotein cholesterol (LDL-C) (in the anamnesis up to 10.57 mmol/L), and two heterozygous probably pathogenic variants in two genes: LDLR (ENSP00000454071.1:p.Gly592Glu) and APOB (ENSP00000233242.1:p.Arg3527Gln). While following a strict lipid-lowering diet with restrictions on cholesterol and animal fats and taking a triple lipid-lowering therapy consisting of atorvastatin 40 mg/day, ezetimibe 10 mg/day, and alirocumab 150 mg subcutaneously once every two weeks, it was possible to reduce the level of LDL-C from 10.57 mmol/L to 3.29 mmol/L (a reduction of 68.9%). Failure to achieve the target level of LDL-C in the patient is associated, firstly, with the extremely high initial value and, secondly, apparently, with the reduced effectiveness of lipid-lowering therapy for complex genetic disorders.
