Introduction

There is a significant correlation between elevated LDL cholesterol (LDL-C) levels sustained from childhood and future vascular disease. The study aimed to evaluate the effectiveness and safety of the therapy chosen for children with lipid disorders.

Material and methods

The study group consisted of 37 children with increased LDL-C (13 boys) aged 8.99 ±4.03 years. After 6 months of behavioral treatment, study group was divided into G1 (n = 24) which continued non-pharmacological treatment supported by dietary supplements and G2 (n = 13) in which statin (5–10 mg/day) was added to non-pharmacological treatment. Analysis included: BMI Z-score, total cholesterol (TCh), LDL-C, HDL cholesterol (HDL-C) and triglycerides (TG) measured at several time points.

Results

The concentrations of TCh and LDL-C before treatment were significantly higher in G2 than in G1 (p < 0.001). Due to the treatment, these differences were no longer noticeable at the last visit. In G1 and G2 concentrations of TCh and LDL-C were reduced significantly, greater reduction after the treatment in TCh and LDL-C was observed in G2 than in G1. Moreover, in G1 we noticed reduction of TG after treatment (p < 0.05). The BMI Z-score did not change significantly through the treatment in both groups. G1 also showed a significant negative correlation between BMI Z-score and HDL-C before and after treatment (r = –0.57, p = 0.009; r = –0.52, p = 0.02). Same relationship was noticed also in G2 after treatment (r = 0.67, p = 0.05).

Conclusions

In children with dyslipidemia, regardless of its background, statin therapy is the most effective in lowering LDL-C. However, therapy with lipids-lowering supplements seems to be safe and effective.
