RESUMEN
Resumen Introducción:
Los prematuros extremos tienen mayor incidencia de Hipertensión Arterial (HTA) y riesgo de daño renal, secundario a un menor número de glomérulos con la consiguiente hiperfiltración de los remanentes.Objetivo:
Evaluar la prevalencia de cifras tensionales alteradas usando monitorización ambulatoria de presión arterial (MAPA) y marcadores de daño renal en escolares con antecedentes de prematurez extrema. Pacientes yMétodo:
Realización medición aislada de presión arterial, MAPA, y evaluación de función renal en el seguimiento de prematuros extremos de edad escolar.Resultados:
Se reclutaron 30 pacientes, obteniéndose mediciones válidas de MAPA en 19 casos, de los cuales nueve (47,4%) presentaron alteraciones, principalmente ausencia de diferencia de presión día noche. No hubo alteraciones de la función renal en ellos.Discusión:
Nuestro estudio detectó una alta prevalencia de alteraciones en MAPA en escolares con antecedentes de prematurez extrema, principalmente la ausencia de diferencia de presión día noche, que se relaciona con mayor riesgo de progresión a HTA. Se resalta la importancia de realizar MAPA dentro del estudio en pacien tes con factores de riesgo de desarrollar HTA a fin de detectar en forma precoz alteraciones y realizar un manejo y seguimiento estrecho.ABSTRACT
Abstract Introduction:
Extremely premature children have a higher incidence of High Blood Pressure (HBP) and risk of renal damage due to decreased glomerular count with consequent hyperfiltration of the remnants.Objectives:
To assess the prevalence of altered blood pressure values in outpatient measurement and ambulatory blood pressure monitoring (ABPM) in preterm infants ≤ 32 weeks and/ or ≤ 1,500 g birth weight between 5 and 7 years of age, as well as the presence of early renal damage markers. Patients andMethods:
An isolated measurement of blood pressure, ABPM and laboratory tests (microalbuminuria/creatininuria ratio in an isolated urine sample, serum creatinine, blood urea nitrogen and urinalysis) were performed.Results:
30 patients were recruited, of whom valid measu rements of ABPM were obtained in 19 cases, of which nine (47,4%) presented some abnormalities, principally nocturnal day/night difference or DIP absent. No abnormal laboratory tests were found.Discussion:
Our study detected a high prevalence of abnormalities in ABPM principally DIP absence, which has been related to an increased risk of progression to hypertension. The importance of per forming ABPM in the study is emphasized in patients with risk factors for developing hypertension in order to detect early alterations and close management and follow-up.
