RESUMEN
It is suggested that hyperuricemia is a marker of cardiovascular risk in human adults with metabolic syndrome(MS). The C677T polymorphism in the gene encoding the enzyme methylenetetrahydrofolate reductase (MTHFR) is associated with hyperuricemia. Data on factors associated with uricemia in human adults with MS genotyped for this polymorphism are lacking. We aimed to investigate the factors associated with uricemia in human adults with MSgenotyped for the C677T polymorphism in the MTHFR gene. Cross-sectional study was conducted with 63 human adults (24 men and 39 women) with MS. Body weight, body mass index, waist circumference, body fat, glycemia, lipidprofile, uricemia, insulinemia, homocysteinemia, plasmafolate, erythrocyte folate, blood pressure, smoking, diuretics use, usual dietary alcohol and protein intakes, and the presence of the C677T polymorphism in the MTHFR gene were assessed. Hyperuricemia was observed in 16 (25.4%)human adults (10 men and 6 women). In the group, 33% (n= 21) showed the C677T polymorphism, being 19 heterozygous and 2 mutant homozygous. A significant association between hyperuricemia and C677T polymorphism was not verified. Uricemia was positively associated with homocysteinemia (r = 0.43, p < 0.05), triglyceridemia (r = 0.41,p<0.05), serum concentrations of very-low-density lipoprotein(r = 0.27, p< 0.05) and the habitual alcohol intake (r =0.37, p < 0.05). However, only homocysteinemia, triglyceridemia, and habitual alcohol intake remained in the final model of linear regression. In human adults with MS genotyped for the C677T polymorphism in the MTHFR gene, uricemia was positively associated with homocysteinemia, triglyceridemia and the habitual alcohol intake (AU)
ABSTRACT
Sugiérese que la hiperuricema sea un factor de riesgo cardiovascular en humanos adultos con síndrome metabólico(SM) El polimorfismo C677T en el gen metilenotetrahidrofolato reductasa (MTHFR) ha sido asociado com la hiperuricemia. Datos sobre los factores asociados con la uricemia en humanos adultos con SM genotipados para el polimorfismo C677T en el gen MTHFR son inexistentes. Se objetivó investigar los factores asociados con lauricemia en individuos con SM genotipados para el polimorfismo C677T. Se ha realizado un estudio transversal con 63 humanos adultos (24 hombres y 39 mujeres). Fueron evaluados peso, altura, índice de masa corporal, circunferencia de la cintura, grasa corporal total, glucemia, uricemia, insulinemia, homocisteinemia, folato plasmático, folato en los eritrocitos, presión arterial, tabaquismo,uso de diuréticos, ingesta habitual de proteínas dietéticas y de alcohol y la presencia del polimorfismo C677T. No fue encontrado asociación significativa entre el polimorfismo C677T y la uricemia. Fue verificado que un 25,4% (n = 16) do los individuos presentaban hiperuricemia (10 hombres y 6 mujeres). Se verificó que un 33%(n = 21) de los individuos presentaron el polimorfismo C677T (19 heterocigotos y 2 homocigotos polimórficos). La uricemia se asoció con los niveles de homocisteina (r =0,43, p < 0,05), trigicéridos (r = 0,41, p < 0,05) y de lipoproteínas de muy baja densidad (r = 0.27, p < 0,05) y conla ingesta de alcohol (r = 0,37, p < 0,05). Sin embargo, sólo la homocisteinemia, la trigliceridemia y la ingesta habitual de alcohol permanecerán en el modelo final de regresión lineal. En los humanos adultos con SM genotipados para el polimorfismo C677T en el gen MTHFR, la uricemia se asoció positivamente con los niveles de homocisteína y triglicéridos y con la ingesta habitual de alcohol (AU)
