ABSTRACT

As primeiras descrições da síndrome da imunodeficiência adquirida (Aids) associavam-se à síndrome de emaciamento, e os distúrbios metabólicos às alterações na composição corporal. Após a introdução da terapia anti-retroviral altamente ativa (HAART), houve declínio na desnutrição, e surge a lipodistrofia como importante distúrbio metabólico. A Aids também se caracteriza por distúrbios hormonais, principalmente no eixo hormônio de crescimento/fator de crescimento insulina-like tipo 1 (GH/IGF-1). O uso do GH recombinante humano (hrGH) foi inicialmente indicado na síndrome de emaciamento, a fim de aumentar a massa muscular. Embora também não existam dúvidas quanto aos efeitos do hrGH na lipodistrofia, a diminuição na sensibilidade à insulina limita o seu uso, o qual ainda não está oficialmente aprovado. A diversidade nos esquemas de tratamento é outro limitante do uso dessa medicação em pacientes com Aids. Esta revisão apresenta os principais distúrbios endócrino-metabólicos associados à Aids e ao uso do hrGH nessas condições.


Acquired Immunodeficiency Syndrome (Aids) was initially related to HIV-associated wasting syndrome, and its metabolic disturbances to altered body composition. After Highly Active Antiretroviral Therapy (HAART) was started, malnutrition has declined and HIV-associated lipodystrophy syndrome has emerged as an important metabolic disorder. Aids is also characterized by hormonal disturbances, principally in growth hormone/insulin-like growth factor 1 (GH/IGF-1) axis. The use of recombinant human GH (hrGH) was formerly indicated to treat wasting syndrome, in order to increase lean body mass. Even though the use of hrGH in lipodystrophy syndrome has been considered, the decrease in insulin sensitivity is a limitation for its use, which has not been officially approved yet. Diversity in therapeutic regimen is another limitation to its use in Aids patients. The present study has reviewed the main HIV-related endocrine-metabolic disorders as well as the use of hrGH in such conditions.
