LEHMANN F, Paula  y  CANO SC, Francisco. Cardiovascular disease in pediatric patients under chronic peritoneal dialysis. Rev. chil. pediatr. [online]. 2017, vol.88, n.2, pp.236-242. ISSN 0370-4106.

Peritoneal dialysis (PD) is the most common renal replacement therapy used in pediatric patients with end stage renal disease. This population has a mortality rate 1,000 times greater compare to pediatric population, mainly due to cardiovascular causes. Objective: To characterize pediatric patients on chronic PD in relation to dialysis and cardiovascular outcome. Patients and Methods: Cross sectional study. Patients in stable PD according to DOQI criteria were selected. Epidemiological, dialytic, biochemical and cardiovascular variables were registered. Left Ventricular Mass Index (LVMI) was calculated by height/age (g/m2.7). Left Ventricular Hypertrophy (LVH) was diagnosed with > 38.6 g/m2.7, severe LVH > 51 g/m2.7. Data were analyzed using STATA 11.0. continuous variables using ANOVA test and categorical variables were analyzed using χ2 test or Fisher’s exact test. Results: 21 patients, 11 males. Mean age 9.2 ± 3.52 years. The most frequent diagnosis was renal dysplasia (52%). Residual and Peritoneal KtV were 0.8 and 1.9 respectively. Fifty-two percent of patients showed LVH, 91% in severe range. A significant relationship between ultrafiltration/m2 and systolic blood pressure was depicted. Also a significant relationship between left ventricular mass index and hemoglobin (p < 0.05) was founded. Conclusions: The majority of the population showed left ventricular hypertrophy -particularly severe LVH-, which confirms an increased CV risk in this population. Blood pressure and loss of ultrafiltration were founded to be correlated to LVH.
