ABSTRACT
BACKGROUND: Pediatric kidney transplant patients have an increased risk of developing arterial hypertension, dyslipidemia, carbohydrate intolerance and diabetes mellitus, risk factors associated with increased cardiovascular morbidity and mortality. OBJECTIVE: This study evaluates the frequency of arterial hypertension, dyslipidemia and alteration in carbohydrate metabolism in a cohort of pediatric kidney transplant patients during 2006-2016 at the Pablo Tobon Uribe Hospital, in Colombia. MATERIAL AND METHODS: Retrospective descriptive study in which descriptive statistics were used. Additionally, a bivariate analysis was performed to compare patients according to the outcome of arterial hypertension, dyslipidemia and alteration in carbohydrate metabolism. RESULTS: From a total of 48 pediatric kidney transplants in the period studied, complete information was obtained from 43 patients at one year of follow-up. There was a post-transplant frequency of hypertension of 86%, dyslipidemia 48%, carbohydrate intolerance 14% and diabetes of 2%. CONCLUSIONS: In the evaluated cohort a high frequency of arterial hypertension and dyslipidemia was found after kidney transplantation. The development of early diagnosis and treatment guidelines is suggested to reduce the impact of these diseases associated with cardiovascular risk in adult life.
INTRODUCCIÓN: Los pacientes pediátricos con trasplante renal tienen un riesgo incrementado de desarrollar hipertensión arterial, dislipidemia, intolerancia a los hidratos de carbono y diabetes mellitus, factores de riesgo que se asocian con una mayor morbilidad y mortalidad cardiovascular. OBJETIVO: Evaluar la frecuencia de hipertensión arterial, dislipidemia y alteración en el metabolismo de los hidratos de carbono en una cohorte de pacientes pediátricos con trasplante renal durante 2006-2016 en el Hospital Pablo Tobon Uribe, en Colombia. MATERIAL Y MÉTODOS: Estudio descriptivo retrospectivo en el cual se utilizó estadística descriptiva. Adicionalmente se realizó análisis bivariado para comparar pacientes según el desenlace hipertensión arterial, dislipidemia y alteración en el metabolismo de los hidratos de carbono. RESULTADOS: De un total de 48 trasplantes renales pediátricos en el periodo estudiado, se obtuvo información completa de 43 pacientes al año de seguimiento. Se observó una frecuencia postrasplante de hipertensión arterial del 86%, de dislipidemia del 48%, de intolerancia a los hidratos de carbono del 14% y de diabetes del 2%. CONCLUSIONES: En la cohorte evaluada se encontró una alta frecuencia de hipertensión arterial y dislipidemia postrasplante renal. Se sugiere el desarrollo de guías de diagnóstico precoz y tratamiento que permitan disminuir el impacto de estas enfermedades asociadas a riesgo cardiovascular en la vida adulta.

Introducción: la hidronefrosis es una de las malformaciones congénitas detectadas comúnmente en la ecografía prenatal. Los casos moderados y graves frecuentemente se asocian a anomalías de la vía urinaria. Objetivo: describir las causas de la hidronefrosis, la frecuencia de su diagnóstico prenatal y la de enfermedad renal crónica (ERC) en una serie de pacientes pediátricos. Materiales y métodos: estudio descriptivo, retrospectivo de 924 pacientes atendidos entre 1960 y 2010 en un hospital universitario de Medellín. Resultados: hubo predominio de hombres (64,3%); en el 14,4% el diagnóstico fue prenatal. En el 18,3% no se encontraron anomalías urológicas asociadas. Siete de estos (4,2%) llegaron a la ERC. La estenosis pieloureteral fue la anomalía hallada con mayor frecuencia (28,6%) seguida por el reflujo vesicoureteral (21,5%) y las valvas de la uretra posterior (9,4%); el 10,2% de los pacientes llegaron a la enfermedad renal crónica; al agrupar los pacientes de acuerdo con el método utilizado para el diagnóstico de hidronefrosis, el grupo en que se hizo por urografía excretora tuvo ERC en el 11,3%, en contraste con el 8,4% en quienes el diagnóstico se hizo por ecografía renal; por otro lado. al agrupar los pacientes con diagnóstico ecográfico de hidronefrosis prenatal o posnatal, el porcentaje de ERC fue de 4,8% frente a 10,8%, respectivamente. Conclusión: el diagnóstico temprano de la hidronefrosis permite detectar anomalías urológicas susceptibles de seguimiento o corrección quirúrgica. Todavía existe mucha controversia acerca del mejor seguimiento imaginológico para estos pacientes.
Introduction: Hydronephrosis is one of the most common congenital malformations detected on prenatal ultrasounds. Moderate and severe cases are often associated with urological abnormalities. Objective: To describe the causes of hydronephrosis, and the frequency of its prenatal diagnosis and of chronic kidney disease (CKD) in a series of pediatric patients. Materials and methods: A descriptive, retrospective study of 924 patients under 18 years of age seen at a university hospital in Medellín, Colombia, between 1960 and 2010. Results: 64.3% were male. Diagnosis was prenatal in 133 (14.4%). Hydronephrosis was bilateral in 198 patients (28.5%). In 169 (18.3%) no associated urological abnormality was found; 7 of these (4.2%) reached CKD. Ureteropelvic stenosis was diagnosed in 216 (23.3%) followed by vesicoureteral reflux in 199 (21.5%) and posterior urethral valves in 87 (9.4%); 93 (10.2%) reached CKD. When hydronephrosis was diagnosed by urography, patients developed CKD in 11.3% vs. 8.4% in those whose diagnosis was made by ultrasound; frequency of CKD was 4.8% when diagnosis by ultrasound was prenatal, and 10.8% when it was postnatal. Conclusion: Early diagnosis of hydronephrosis allows the detection of urologic abnormalities susceptible to treatment. There is controversy about the best imaginological method for the follow-up of these patients.

Hydronephrosis is one of the most common congenital malformations detected on prenatal ultrasounds. Moderate and severe cases are often associated with urological abnormality. OBJECTIVE To describe a series of pediatric patients diagnosed with hydronephrosis determining their etiology, prenatal diagnosis and frequency of chronic kidney disease (CKD). MATERIALS AND METHODS A descriptive, retrospective study. RESULTS The records of 924 patients between the ages of 0 and 18 years were evaluated, 35.7% female and 64.3% male. In 14.4% (133) the diagnosis was prenatal. Hydronephrosis was bilateral in 198 patients (28.5%). In 18.3% (169) no associated urological abnormality was found, reaching 4.2% in CKD (7). Ureteropelvic stenosis was diagnosed in 23.3% (216) followed with 21.5% VUR (199) and posterior urethral valves in 9.4% (87), reaching 10.2% ERC (93). When the hydroneprhosis was diagnosed by urography, those patients presented 11.3% of chronic kidney disease vs. 8.4% in whom the diagnosis was made by ultrasound, when the hydronephosis diagnosed was by prenatal vs postnatal ultrasound, the percentage of CKD was 4.8% vs 10.8%, respectively. CONCLUSION Early diagnosis of hydronephrosis allows the detection of urologic abnormalities susceptible of treatment. Although there are still many questions about which one is the ideal strategy of follow up; the ultrasonography, voiding cystourethrogram, urography, scintigraphy and magnetic resonance urography in selected patients are the most useful tools in order to evaluate urinary tract anomaly.
