RESUMO
Resumen OBJETIVO: Emitir recomendaciones para la vigilancia y seguimiento de pacientes embarazadas con diabetes mellitus tipos 1, 2 y gestacional con base en la experiencia de un grupo de especialistas y en lo reportado en la bibliografía, desde la perspectiva del sistema de salud mexicano. MATERIALES Y MÉTODOS: Se utilizó la metodología del panel Delphi modificado, mediante la unanimidad de criterios de un grupo de especialistas en Ginecoobstetricia, Biología de la Reproducción y Medicina Materno Fetal mexicanos, tomando en cuenta un nivel de unanimidad del 80% de los participantes. RESULTADOS: Con base en un ejercicio de consenso se recomienda el monitoreo continuo de la glucosa en todas las pacientes embarazadas con diabetes mellitus tipos 1 y 2 a partir del primer trimestre de la gestación. En pacientes con diabetes gestacional considerar, a partir del segundo o tercer trimestre, el monitoreo continuo de la glucosa en usuarias de insulina o en descontrol glucémico, dependiendo del momento en que se diagnostique la diabetes gestacional, del descontrol glucémico y de la necesidad de insulina. La hemoglobina glucosilada y el tiempo en las concentraciones límite también son métricas de control glucémico. CONCLUSIONES: El monitoreo continuo de la glucosa tiene ventajas en: menos complicaciones perinatales, detección oportuna y reducción de eventos de hiper o hipoglucemia, menor descontrol, ajuste de dosis respecto del tratamiento con insulina y mejora en los hábitos para controlar las concentraciones de glucosa.
Abstract OBJECTIVE: To issue recommendations for the surveillance and follow-up of pregnant patients with types 1, 2 and gestational diabetes mellitus based on the experience of a group of experts and on what is reported in the literature, from the perspective of the Mexican health system. MATERIALS AND METHODS: A modified Delphi Panel methodology was performed, through consensus among gynecology, reproductive biologist, and fetal-maternal specialists, and an 80% consensus of all participants. RESULTS: Based on the consensus exercise, we recommend continuous glucose monitoring in all pregnant patients with type I and II diabetes starting on the first trimester; meanwhile in patients with gestational diabetes, continuous monitoring should be considered in patients treated with insulin or uncontrolled glycemia, starting in the second or third trimester, depending on the moment of diagnosis, glycemic levels and insulin requirements, taking into account HbA1c levels and time in range as well as glycemic control metrics. CONCLUSIONS: Continuous glucose monitoring has advantages including the reduction of perinatal complications, timely detection, reduction in the number of hyper/hypoglycemia events, fewer uncontrolled patients, and the capacity for insulin dosage adjustments and improvement of habits for glucose control.
RESUMO
Preeclampsia is characterized by an imbalance in angiogenic factors. Urinary prolactin (PRL) levels and its antiangiogenic PRL fragments have been associated with disease severity. In this study, we assessed whether these biomarkers are associated with an increased risk of adverse maternal and perinatal outcomes in preeclamptic women. We studied 501 women with preeclampsia attended at a tertiary care hospital. Serum concentrations of soluble fms-like tyrosine kinase-1 (sFlt-1), placental growth factor (PlGF), and soluble endoglin (sEng), as well as urinary PRL levels, were measured by enzymed-linked immunosorbent assay. Antiangiogenic PRL fragments were determined by immunoblotting. The risk for any adverse maternal outcome and for having a small-for-gestational-age infant was higher among women with sFlt-1/PlGF ratios, sEng, and urinary PRL level values in the highest quartile (odds ratios ≥ 2.7), compared with the lowest quartile. Both urinary PRL levels and the presence of antiangiogenic PRL fragments were more closely associated with the risk of specific adverse maternal outcomes (placental abruption, hepatic hematoma or rupture, acute renal failure, pulmonary edema, maternal death, and need for endotracheal intubation, positive inotropic drug support, and hemodialysis; odds ratios ≥ 5.7 and ≥ 4.7, respectively) than either sFlt-1/PlGF ratio or sEng alone. We concluded that in preeclamptic women at the time of initial evaluation, sFlt-1/PlGF ratio and sEng are associated with increased risk of combined adverse maternal outcomes. However, urinary PRL concentrations and its antiangiogenic fragments appear to be better predictors of an adverse maternal outcome and may be useful for risk stratification in preeclampsia.
