Balanço entre ácidos graxos ômega-3 e 6 na resposta inflamatória em pacientes com câncer e caquexia
Palabras clave:
ácidos graxos, caquexia, desnutrição, inflamação, neoplasiasResumen
O emagrecimento, associado à perda de massa magra, é um fenômeno observado com freqüência em pacientes com câncer. Tal condição predispõe o paciente ao maior risco de infecções, pior resposta aos tratamentos implantados e, como conseqüência, desfavorece o prognóstico de cura. Além disso, a desnutrição também está associada à pior qualidade de vida. Dessa forma, algumas terapias têm sido propostas na tentativa de reverter o catabolismo, por meio da atenuação da resposta inflamatória, observado em grande porcentagem de pacientes com câncer e caquexia. Entre elas, a suplementação com ácidos graxos da família ômega-3 pode representar uma estratégia na redução da formação de citocinas pró-inflamatórias, favorecendo a tolerância metabólica dos substratos energéticos e atenuando o catabolismo protéico, com o intuito de melhorar o prognóstico de cura de pacientes com câncer. Entretanto, os estudos mostram alguns resultados conflitantes da suplementação com ômega-3 na resposta imunológica. Por outro lado, em pacientes com câncer, os ensaios clínicos mostraram atenuar a resposta inflamatória e melhorar o estado nutricional. O objetivo deste artigo é realizar uma revisão criteriosa do assunto.
