Abstract
A apolipoproteína (apo) B faz parte das frações lipídicas aterogênicas (Qm e VLDL remanescentes, LDL,Lp (a)) e a apo A-I da fração não-aterogênica (HDL). A determinação dessas apos é direta, automatizada, padronizada, com coeficiente de variação pequeno e não requer jejum. Os autores revisaram os principais estudos clinico-epidemiológicos e de intervenção terapêutica nas hiperlipidemias nos quais as apos B e A-I foram avaliadas. Esses estudos sinalizaram a importância das apos B e A-I no prognóstico de risco e permitiram que especialistas recomendassem a relação apo B / apo A-I como alternativa à já utilizada CT / HDL-c no cálculo de risco. Aguarda-se posicionamento futuro das Diretrizes para incluir as apos na avaliação do risco individual e objetivo terapêutico a ser atingido. Os autores sugerem que, na prática clínica, a determinação de apo B deve ser reservada ao coronariopatas com valores desejáveis de LDL-c ou na impossibilidade de seu cálculo e a de apo A-I, quando os valores de HDL-c são muito baixos.
Apolipoprotein (apo) B is present in atherogenic lipoproteins (remnant Qm and VLDL, LDL and Lp (a)) and apo A is present in non-atherogenic lipoprotein (HDL). Measurement of the apos is automated, standardized, with a small variation of coefficient and does not require fasting blood samples. The authors reviewed clinical, epidemiological and therapeutic trials on hyperlipidemia with apo B and A-I evaluation. These works showed the importance of apo B and A-I as cardiovascular risk factors. Experts recommended apo B / apo A-I ratio as an alternative to TC / HDL-c ratio for risk estimate. Future positioning from the Guidelines is expected to include apos in individual risk prediction and as a therapeutic target. The authors suggest that, in clinical practice, measurement of apo B is necessary for coronary heart disease patients with desirable LDLc levels or when this assessment is not possible and the measurement of apo A-I if HDL-c values are very low.
