ABSTRACT

OBJETIVOS: Investigar a influência do IGF-I e testosterona sobre o perfil lipídico e glicêmico em homens acromegálicos. MÉTODOS: Foram avaliados 15 homens acromegálicos. RESULTADOS: Os pacientes hipogonádicos apresentaram HDL-c mais baixo e triglicérides, LDL-c, glicemia, GH e IGF-I mais elevados. Os valores de IGF-I correlacionaram-se inversamente com HDL-c (r = - 0,57, p = 0,04) e diretamente com triglicerídeos (r = 0,62, p = 0,01) e glicemia (r = 0,66, p = 0,008), enquanto a testosterona correlacionou-se diretamente com HDL-c (r = 0,52, p = 0,05) e inversamente com triglicerídeos (r = - 0,57, p = 0,02); LDL (r = - 0,53, p = 0,04) e glicemia (r = - 0,54, p = 0,03). O IGF-I e a testosterona correlacionaram-se inversamente (r = - 0,585, p = 0,028). CONCLUSÃO: Estes resultados sugerem que a intervenção mais importante na redução do risco cardiovascular nesses pacientes é o controle da atividade da doença.


OBJECTIVES: To evaluate the influence of IGF-I and testosterone on the lipid profile and glycemia in acromegalic men. METHODS: Fifteen acromegalic men were studied. RESULTS: The hypogonadic patients presented lower HDL-c and higher tryglicerides, LDL-c, glycemia, GH and IGF-I. Serum IGF-I was inversely correlated with HDL-c (r = - 0.57, p = 0.04) and directly with TG (r = 0.62, p = 0.01) and glycemia (r = 0.66, p = 0.008), whereas serum testosterone correlated directly with HDL-c (r = 0.52, p = 0.05) and inversely with TG (r = - 0.57, p = 0.02), LDL-c (r = - 0.53, p = 0.04) and fasting blood glucose (r = - 0.54, p = 0.03). IGF-I and testosterone were inversely correlated (r = - 0.585, p = 0.028). CONCLUSION: These results suggest that the most important intervention in reducing cardiovascular risk in these patients is to control the activity of the disease.
