ABSTRACT

OBJETIVO: Avaliar a presença de lipodistrofia clínica em crianças com síndrome da imunodeficiência adquirida e relacioná-la com o esquema antirretroviral utilizado, alterações do perfil lipídico e resistência insulínica. MÉTODOS: Por meio de estudo transversal, foram avaliadas 30 crianças e adolescentes (mediana de idade = 9,1 anos) com síndrome da imunodeficiência adquirida, no período entre 2004 e 2005. As avaliações clínico-laboratoriais incluíram: classificação da infecção pelo HIV, medidas antropométricas (peso e estatura), glicemia e insulina séricas e perfil lipídico (LDL-c, HDL-c, triglicérides). A lipodistrofia foi definida por parâmetros clínicos. O teste do qui-quadrado foi utilizado na análise estatística. RESULTADOS: Todos os pacientes recebiam terapia antirretroviral regularmente (mediana de tempo de uso = 28,4 meses), 80 por cento utilizavam três drogas em associação (terapia fortemente ativa) e 30 por cento usavam inibidores de protease. Lipodistrofia e dislipidemia foram observadas em 53,3 e 60 por cento dos pacientes, respectivamente. Crianças que utilizavam terapia fortemente ativa com inibidor de protease apresentaram maior percentual de lipodistrofia mista, com diferença estatisticamente significante em relação ao grupo com terapia fortemente ativa sem inibidor de protease e ao grupo sem terapia fortemente ativa (44,4 versus 16,7 por cento; p = 0,004). Não se observou diferença estatisticamente significante entre presença de lipodistrofia e gênero, idade (> 10 anos), alterações do perfil lipídico e resistência insulínica. CONCLUSÕES: A elevada prevalência de dislipidemia e lipodistrofia verificada nas crianças com síndrome da imunodeficiência adquirida, mostrando relação com o esquema antirretroviral empregado, pode significar um risco elevado para o desenvolvimento futuro de complicações, especialmente as cardiovasculares.


OBJECTIVE: To evaluate the presence of clinical lipodystrophy in children with the acquired immunodeficiency syndrome and to relate it to the antiretroviral regimen employed, to changes in lipid profile and to insulin resistance. METHODS: This was a cross-sectional study that evaluated 30 children and adolescents (median age = 9.1 years) with the acquired immunodeficiency syndrome during 2004 and 2005. The following clinical and laboratory evaluations were performed: classification of HIV infection, anthropometric measurements (weight and height), serum glycemia, serum insulin and lipid profile (LDL-c, HDL-c, triglycerides). Lipodystrophy was diagnosed using clinical parameters. The chi-square test was used for statistical analysis. RESULTS: All of the patients were taking antiretroviral therapy regularly (median duration of 28.4 months); 80 percent were on three drugs in combination (highly active therapy) and 30 percent were on protease inhibitors. Lipodystrophy and dyslipidemia were observed in 53.3 and 60 percent of the patients, respectively. Children on a highly active therapy regimen with protease inhibitors exhibited a higher percentage of mixed lipodystrophy; the difference between these children and the group on highly active therapy without protease inhibitors and the group not on a highly active therapy was statistically significant (44.4 vs. 16.7 percent; p = 0.004). There was no statistically significant association between the presence of lipodystrophy and sex, age (> 10 years), changes to the lipid profile or insulin resistance. CONCLUSIONS: The elevated prevalence of dyslipidemia and lipodystrophy observed among children with acquired immunodeficiency syndrome, which exhibited a relationship with the antiretroviral regimen employed, may represent an increased risk for future complications, in particular cardiovascular problems.
