Dynamic changes of lipid profile in Romanian patients with Gaucher disease type 1 under enzyme replacement therapy: a prospective study

Background Dyslipidemia in Gaucher disease includes reduced total, low-density lipoprotein (LDL)-, and high-density lipoprotein (HDL)-cholesterol (C). No prospective analysis of lipid profile changes in treatment-naïve patients under enzyme replacement therapy (ERT) is available. Methods We analyzed lipid profile changes during ERT in a prospective controlled manner. Twelve treatment-naïve patients, Gaucher disease type 1 (GD1), 29.5 ± 12.9 years, 4M/8F. Diagnosis was made by enzymatic measurement and mutational analysis. Total-, LDL-, and HDL-C, triglycerides (TG), and LDL subfractions were assessed before the start of ERT with imiglucerase and biannually for 3 years. Patients were matched with healthy controls before and after 3 years of ERT. Results At baseline, we found severely reduced HDL-C concentrations (23.6 ± 5.4 mg/dl) and enhanced LDL/HDL ratios (3.1 ± 0.7). HDL-C increased after 6 months (29.2 ± 5.7, p = 0.023), LDL/HDL ratio decreased after 30 months (2.5 ± 0.5, p = 0.039). TG, even not consistently enhanced at baseline (128 ± 31.3 mg/dl), yet higher than in controls ( p
