ResumenObjetivos: Comparar los niveles de homocisteína según el estado menopáusico en un grupo de mujeres atendidas en un hospital de Lima. Diseño: Estudio descriptivo. Lugar: Centro de Investigación de Bioquímica y Nutrición, Facultad Medicina, Universidad Nacional Mayor San Marcos, Lima, Perú. Participantes: Mujeres de 40 a 60 años de edad. Intervenciones: En 97 mujeres de 40 a 60 años de edad atendidas en el Hospital San Bartolomé, Lima, Perú, se determinó el estado menopáusico en base a evaluación clínica y dosaje de FSH y estradiol en sangre. Para determinar la homocisteína plasmática se usó el método de inmunoanálisis de polarización de fluorescencia. Principales medidas de resultados: Niveles de homocisteína en sangre. Resultados: Los niveles de homocisteína hallados estuvieron dentro de los valores referenciales internacionales (5 a 15 µmol/L). Las mujeres posmenopáusicas presentaron niveles de homocisteína significativamente mayores comparados con las mujeres premenopáusicas (p<0,05). Conclusiones: Los niveles plasmáticos de homocisteína fueron mayores en las mujeres menopáusicas y su incremento podría ser considerado en la predicción de la enfermedad cardiovascular. Palabras clave: Homocisteína, premenopausia, posmenopausia, HFE, estradiol, enfermedades cardiovasculares. Abstract Objectives: To compare serum homocysteine levels according to menopausal status in a group of women. Design: Descriptive study. Setting: Biochemistry and Nutrition Research Center, Faculty of Medicine, Universidad Nacional Mayor de San Marcos, Lima, Peru. Participants: Women 40 to 60 year-old. Interventions: The menopausal status was determined clinically and by serum FSH and estradiol in 97 women 40 to 60 year-old attended at San Bartolome Hospital, Lima, Peru. Plasma homocysteine was determined by fluorescence polarization immunoanalysis. Main outcome measures: Homocysteine levels. Results: Homocysteine levels were within international referential values (5-15 µmol/L). Postmenopausal women levels were significantly higher compared to premenopausal women levels (p< 0.05). Conclusions: Homocysteine levels are increased in menopausal women and could be considered in cardiovascular disease prediction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
