  • Abstract Heterozygous familial hypercholesterolemia (FH) is the most common inherited type of primary hyperlipidemia. Patients with familial hypercholesterolemia have an increased level of LDL cholesterol since childhood, and present early associated cardiovascular disease. Ezetimibe reduces LDL by blocking sterol absorption in enterocytes.

    Aim: to show our experience on the use of ezetimibe in children and adolescents with familial hypercholesterolemia, with short and medium term follow-up.

    Patients and Methods: Retrospective and longitudinal study. Patients who were receiving ezetimibe as monotherapy from 2003 to 2009 were included. The primary efficacy parameter was the effect of ezetimibe on the LDL after three months of treatment. Serum levels of aspartate aminotransferase, alanine aminotransferase and creatine kinase were monitored. Patients were asked if they experienced any side effect with the ezetimibe treatment.

    If the Patients did not achieve therapeutical goals with ezetimibe as monotherapy a statin was added. Outcome at medium term follow-up is analysed.

    Results: The study included a total of 32 patients. The mean age at the start of ezetimibe was 9.5 years (range: 2 to 15.5). The mean total time of Ezetimibe was 2.45 years (r: 0.4 - 5.9).The decrease in mean LDL levels was -25.7%±12.3 or 59.5±34 mg% (P<.0001; 95% CI: 47.3-71.5, t test). There were no side effects with ezetimibe monotherapy. At the end of the study, 11 patients required added statins due to failing to achieve the treatment goal.

    Conclusions: Ezetimibe is effective and safe for children and adolescents with FH in short and medium term follow-up.
