CORELLA AZNAR, Elena Guadalupe et al. Evolution of cardiometabolic risk among childhood acute leukemia survivors. Nutr. Hosp. [online]. 2016, vol.33, n.3, pp.549-555. ISSN 1699-5198.  https://dx.doi.org/10.20960/nh.260.

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 laukemia and those treated with more aggressive treatments.
