Evoluci贸n del riesgo cardiometab贸lico en pacientes supervivientes de leucemia aguda infantil
Introducci贸n: los supervivientes de leucemia aguda (LA) infantil presentan un riesgo incrementado de alteraciones metab贸licas y cardiovasculares que aumentan su morbimortalidad a largo plazo.Objetivo: estimar la prevalencia de obesidad, resistencia a la insulina, dislipemia e hipertensi贸n arterial como factores de riesgo cardiometab贸lico (FRCM) en un grupo de supervivientes de LA infantil, y analizar las posibles causas asociadas a su desarrollo.Material y m茅todos: estudio observacional retrospectivo en 47 supervivientes de LA tratados en un periodo de 4 a帽os, que recibieron seguimiento durante 10 a帽os.Resultados: el 40% de los participantes presentaron al menos un FRCM durante el seguimiento, siendo la dislipemia (aumento LDL) el m谩s frecuente (38, 3%), seguido de obesidad/sobrepeso (31, 9%) y HTA sist贸lica (23, 4%). El sexo femenino se estableci贸 como factor de riesgo parael desarrollo de todos ellos (RR 1, 6; RR 3, 16; RR 1, 69; p < 0, 05). Ning煤n superviviente desarroll贸 diabetes mellitus, pero s铆 resistencia a la insulina el 19, 4%. Los pacientes con leucemias de peor pron贸stico presentaron mayor riesgo de desarrollar obesidad, resistencia a la insulina y aumento de LDL (RR 3, 56; RR 4, 08; RR 2, 53; p < 0, 05). Los pacientes tratados con trasplante de progenitores hematopoy茅ticos presentaron mayor riesgo de obesidad, aumento de LDL e HTA sist贸lica (RR 2, 86; RR 2, 39; RR 3, 12; p<0, 05). La radioterapia se asoci贸 de igual modo con un incremento de resistencia a la insulina e hipertensi贸n arterial sist贸lica (RR 2, 47; RR 2, 53; p < 0, 05).Conclusiones: existe un aumento en la prevalencia de obesidad/sobrepeso, dislipemia, resistencia a la insulina y alteraci贸n de la tensi贸n arterial sist贸lica en supervivientes de leucemia aguda infantil a lo largo del tiempo, especialmente en aquellos con enfermedades y tratamientos m谩s agresivos.
Background: Survivors of childhood acute leukemia (AL) face an increased risk of metabolic and cardiovascular late effects which increase their long-term morbimotality. Objective: To assess the prevalence of obesity, insulinresistance, dyslipidemia and hypertension as cardiometabolic risk factors in survivors of a childhood AL, and also to determine possible causes for these adverse cardiometabolic traits. Material and methods: A retrospective cohort study of 47 pediatric acute leukemia survivors diagnosed between 0-15 years, with a ten years follow-up. Results: Forty percent of participants had at least one cardiometabolic risk factor. Dyslipidemia (increased LDL cholesterol) was the most frequent (38.3%), secondly overweight/obese (31.9%), followed by systolic hypertension (23.4%). Females in contrast to males had an increased risk of developing all three risk factors (RR 1.6; RR 3.16; RR 1.69; p < 0.05). Only 19.4% of participants developed insulin resistance, while none were diagnosed with diabetes mellitus. High risk acute leukemia survivors were significantly more likely than low risk leukemia survivors to manifest multiple cardiometabolic traits like overweight/obesity, insulin resitance and dyslipidemia (RR 3.56; RR 2.39; RR 2.53; p < 0.05). Also, those who received hematopoietic cell trasplantation had an increased prevalence of overweight/obesity, increased LDL-cholesterol and systolic hypertension. Radiotherapy treatment was also associated with insulin resitance and systolic hypertension (RR 2.47; RR 2.53; p < 0.05). Conclusions: There is an increased risk of overweight/obesity, dyslipidemia, insulin resistance and systolic blood pressure modification in childhood acute leukemia survivors, specially in those who were diagnosed as a high risk acute leukemia and those treated with more aggressive treatments
