Title in Portuguese

Abstract in Portuguese
Nesta dissertação, estudamos o efeito da Rosuvastatina (Ros) sob pacientes hipercolesterolêmicos. Dentro de 180 dias de estudo prospectivo, avaliamos a eficácia da utilização de anticorpos contra a LDL oxidada ou contra sequência peptídica da apolipoproteína B (apoBD) como marcadores no acompanhamento de resposta à droga. Acompanhamos 76 pacientes (Ros.,n=40/cont.,n=36) através das seguintes variáveis: perfil lipídico, TBARS, anticorpos IgG e IgM anti-oxLDL e IgG anti-apoBD. A partir dos resultados obtidos, concluímos que: não houve alterações consideradas significativas dentro do perfil lipídico; o tratamento controle reduziu significativamente TBARS; os anticorpos IgM anti-oxLDL e IgG anti-apoBD foram sensíveis como marcadores e houve redução significativa destes apenas no tratamento com Rosuvastatina; os níveis de anticorpos IgM e IgG anti-oxLDL não são correlacionados; existe correlação direta entre anticorpos IgG anti-oxLDL e anti-apoBD; os níveis de LDL se correlacionam inversamente aos níveis de IgG anti-oxLDL e IgG anti-apoBD.

Abstract in English
In this dissertation, we studied the effect of rosuvastatin (Ros) in hypercholesterolemic patients. During 180 days, we evaluated t if antibodies against oxidized LDL or against a peptide from apolipoprotein B (apoBD) would work as markers to monitor a response to the drug. We enrolled 76 patients (Ros.,n = 40/cont.,n = 36 and used the following variables: lipid profile, TBARS, IgG and IgM anti-oxLDL and IgG anti-apoBD., We conclude that there were no significant changes seen in the lipid profile, the control treatment significantly reduced TBARS ,IgM anti-oxLDL and IgG anti-apoBD were sensitive markers and decreased significantly only in the treatment in Ros group; levels of IgM and IgG anti-oxLDL are not correlated; there is a direct correlation between IgG anti-oxLDL and anti-apoBD; LDL levels correlate inversely with levels of IgG anti-oxLDL and IgG anti-apoBD.
