Efficacy of simvastatin in children with hyperlipidemia secondary to kidney disorders.
Children with hyperlipidemia secondary to renal disease develop premature atherosclerosis and glomerulosclerosis. The aims of this pilot study were to find the dosage and short-term efficacy of simvastatin and potential adverse events in children with chronic kidney diseases. This was a random, double-blind, placebo-controlled, cross-over clinical trial performed on children with hyperlipidemia secondary to kidney disorders. After being placed on a diet for 3 months, patients were randomly placed in one of two balanced group blocks and treated with diet plus placebo or simvastatin at doses of 5 mg for children weighing 30 kg or less and 10 mg for children weighing over 30 kg, for 1 month, and then doubled for two more months. After this treatment, patients were placed on a diet for a 3-month washout period. During the last trial phase, patients previously treated with simvastatin were administered a placebo, and vice versa. A total of 25 patients with ages ranging from 4 years to 17 years were included in the study. A significant decrease in the levels of serum cholesterol (26.4%), low-density lipoprotein (LDL) (35.4%) and triglycerides (23.1%) was noted during the study, primarily during the simvastatin treatments, in which case cholesterol, LDL and triglycerides decreased by 23.3%, 33.7% and 21%, respectively. High-density lipoprotein (HDL) levels increased moderately (10.7%) during the study but without differences during simvastatin treatment. No differences were found across groups with respect to adverse events. In the short-term the combination of diet and simvastatin was effective in lowering hyperlipidemia in children with renal disorders.
