ABSTRACT

Abstract Background: Children with familial hypercholesterolemia may develop early endothelial damage leading to a high risk for the development of cardiovascular disease (CVD). Statins have been shown to be effective in lowering LDL cholesterol levels and cardiovascular events in adults. The effect of statin treatment in the pediatric population is not clearly demonstrated. Objective: To systematically review the literature to evaluate the effects of different statins and dosages in total cholesterol levels in children and adolescents with familial hypercholesterolemia. We also aimed to evaluate statin safety in this group. Methods: PubMed, EMBASE, Bireme, Web of Science, Cochrane Library, SciELO and LILACS databases, were searched for articles published from inception until February 2016. Two independent reviewers performed the quality assessment of the included studies. We performed a meta-analysis with random effects and inverse variance, and subgroup analyses were performed. Results: Ten trials involving a total of 1543 patients met the inclusion criteria. Our study showed reductions in cholesterol levels according to the intensity of statin doses (high, intermediate and low): (-104.61 mg/dl, -67.60 mg/dl, -56.96 mg/dl) and in the low-density lipoprotein cholesterol level: [-105.03 mg/dl (95% CI -115.76, -94.30), I2 19.2%], [-67.85 mg/dl (95% CI -83.36, -52.35), I2 99.8%], [-58.97 mg/dl (95% CI -67.83, -50.11), I2 93.8%. The duration of statin therapy in the studies ranged from 8 to 104 weeks, precluding conclusions about long-term effects. Conclusion: Statin treatment is efficient in lowering lipids in children with FH. There is need of large, long-term and randomized controlled trials to establish the long-term safety of statins.


Resumo Fundamentos: Crianças com hipercolesterolemia familiar podem desenvolver dano endotelial precoce, aumentando o risco de desenvolver doenças cardiovasculares. As estatinas tiveram sua eficácia em diminuir níveis de colesterol LDL e eventos cardiovasculares em adultos comprovada. O efeito das estatinas na população pediátrica não está claramente demonstrado. Objetivo: Revisar sistematicamente a literatura para avaliar os efeitos e a segurança de diferentes estatinas e suas dosagens nos níveis de colesterol total em crianças e adolescentes com hipercolesterolêmica familiar. Métodos: Artigos publicados desde o início até fevereiro de 2016 foram pesquisados nas bases PubMed, EMBASE, Bireme, Web of Science, Cochrane Library, SciELO e LILACS. Dois revisores independentes avaliaram a qualidade dos estudos incluídos. Realizamos meta-análise com efeitos aleatórios e variância inversa. Análises de subgrupos foram realizadas. Resultados: Dez ensaios envolvendo 1.543 pacientes preencheram os critérios de inclusão. Em nosso estudo, as análises demostraram reduções nos níveis de colesterol, de acordo com a intensidade das doses de estatina (alta, intermediária e baixa): (-104,61 mg/dl, -67,60 mg/dl, -56,96 mg/dl) e no nível de lipoproteínas de baixa densidade: [-105,03 mg/dl (IC95% -115.76, -94.30), I2 19.2%], [-67.85 mg/dl (IC95% -83.36, -52.35), I2 99.8%], [-58.97 mg/dl (IC95% -67.83, -50.11), I2 93,8%. A duração da terapia com estatina variou de 8 a 104 semanas, impedindo conclusões sobre os efeitos a longo prazo. Conclusão: O tratamento com estatinas é eficiente na redução de lipídios em crianças com hipercolesterolemia familiar. É necessário realizar ensaios controlados randomizados de longo prazo para estabelecer a segurança do uso de estatinas a longo prazo.
