Objetivos: Evaluar la hipertensión venosa gestacional (HTVG) como factor de riesgo de hipoxia e insuficiencia placentaria con repercusión en el crecimiento fetal, e identificar y caracterizar biomarcadores de daño hipóxico. Metodología: Diseño: Estudio de casos-control anidado en una cohorte. Población: Gestantes que acudan al control habitual en el tercer trimestre (32-35 semanas) de dos centros hospitalarios (HGUGM y HUCD). Estimado una muestra de 503 pacientes. Variables: Características clínicas de las gestantes con y sin hipertensión venosa. Presencia de marcadores de hipoxia en placenta, sangre materna y cordón mediante estudios histopatológico, genómicos y metabolómicos para determinación de: Fenótipo hipóxico: HIF-1alfa, HIF-2alfa, HIF-3alfa, KDM3A, SLC2A1, EGLN-3, CDKN1C y PHLDA2; Activación de transducción celular: PI3K/Akt/mTOR; Eritopoyesis: EPO; Angiogenésis: VEGF; Fenotipo glucolitico: PGK1, ALDA y GLUT-1 y Apoptosis: Bax/Bcl-2, Caspasas, BNIP3 y PARP-1. Resultados perinatales registrados de forma habitual. Análisis estadístico: Se realizará, tanto de la cohorte como del estudio de casos-control, un análisis descriptivo de las variables recogidas, se estimaran las medidas de asociación y sus intervalos de confianza. Finalmente, se generarán los modelos multivariantes para ajustar por los posibles factores de confusión, describiendo las interacciones encontradas. (Spanish)

Objectives: Evaluate gestational venous hypertension (GVH) as a risk factor for hypoxia and placental insufficiency with an impact on fetal growth, and identify and characterise biomarkers of hypoxic damage. Methodology: Design: Case-control study nested in a cohort. Population: Pregnant women who attend the usual control in the third trimester (32-35 weeks) of two hospital centers (HGUGM and huCD). Estimated a sample of 503 patients. Variables: Clinical characteristics of pregnant women with and without venous hypertension. Presence of markers of hypoxia in placenta, maternal blood and cord using histopathological, genomic and metabolomic studies to determine: Hypoxic phenotype: HIF-1alfa, HIF-2alfa, HIF-3alfa, KDM3A, SLC2A1, EGLN-3, CDKN1C and PHLDA2; Cell transduction activation: PI3K/Akt/mTOR; Eritopoyesis: EPO; Angiogenesis: VEGF; Glucolitic phenotype: PGK1, ALDA and GLUT-1 and Apoptosis: Bax/Bcl-2, Caspasas, BNIP3 and PARP-1. Perinatal results recorded on a regular basis. Statistical analysis: A descriptive analysis of the variables collected will be performed from both the cohort and the case-control study. The association measures and their confidence intervals will be estimated. Finally, multivariate models will be generated to adjust for possible confounding factors, describing the interactions found. (English)
