    Abstract:
    BACKGROUND: Early identification of children with familial hypercholesterolemia (FH) makes it possible to start lipid-lowering therapy at a young age in order to prevent cardiovascular disease. Numerous randomized, often placebo-controlled, studies have assessed the efficacy and safety of statins in children with FH. OBJECTIVE: The aim of this pragmatic observational study was to evaluate pravastatin treatment efficacy and tolerability for a long period of time, and to assess how these results translate in 'real-life' clinical practice. METHODS: We analyzed all medical files of young hypercholesterolemic patients referred to two specialized French centers. This population of 185 pravastatin-treated children with FH, with a mean baseline cholesterol level above 300 mg/dL, in most of whom genetic diagnosis was achieved, was followed-up for a mean duration of 2 years 2 months. The mean age for starting pravastatin was 11 years; in one of five children, treatment was started before the age of 8 years, mostly because of severe hypercholesterolemia or a family history of coronary heart disease. RESULTS: A 16.9-19.2% decrease in total cholesterol level (21-24% for low-density lipoprotein cholesterol) was observed. Growth and puberty were not affected by statin treatment. A review of the medical files showed that 13% of children had side effects, most of which were minor; four of these children had muscular symptoms possibly related to the treatment. This frequency is lower than that observed in adults, and comparable to other studies in children. CONCLUSIONS: In this large cohort of FH children, the efficacy and tolerability of pravastatin therapy in real-life conditions was demonstrated to be similar to that in randomized controlled studies.
