A family history of renal lithiasis in children diagnosed of urinary tract infection by Escherichia coli

Introduction: Urinary tract infections (UTI) caused by Escherichia coli (E. coli) are common in patients with idiopathic hypercalciuria. As both UTI and hypercalciuria (prelithiasis) have a genetic basis, we wanted to know whether the family history of urolithiasis is more common in children with UT...

description Introduction: Urinary tract infections (UTI) caused by Escherichia coli (E. coli) are common in patients with idiopathic hypercalciuria. As both UTI and hypercalciuria (prelithiasis) have a genetic basis, we wanted to know whether the family history of urolithiasis is more common in children with UTIs caused by E. coli. Secondarily, we wondered if the renal scars are more common in children with prelithiasis. Material and methods: Ambispective study with collected data from 104 patients (40 male, 64 female) followed after having been diagnosed of UTI by E. coli at least once. These patients were asked about the existence of urolithiasis in relatives. The calcium and citrate urinary elimination was quantified in 80 children. Results: In the total sample, family history was positive for urolithiasis in a significantly higher frequency in those children (n = 71; 68.3%) than in the control population in our area (29.7%; previously published data). Prelithiasis frequency in children with UTI was 47.5% (38/80). An association was observed between the diagnosis of prelithiasis both with family history of urolithiasis (p = 0.030) and the diagnosis of vesicoureteral reflux (p = 0.034). Children who developed renal scarring had an increased risk of prelithiasis (OR 5.3; p = 0.033). Conclusions: The frequency of family history of urolithiasis in children with UTI caused by E. coli is very high. Based on our results we hypothesize that the predisposition to lithiasis can involve a constitutively altered defense to E. coli and, therefore, a greater possibility for renal scars. Resumen: Introducción: Las infecciones de la vía urinaria (IVU) causadas por Escherichia coli (E. coli) son frecuentes en pacientes con hipercalciuria idiopática. Al ser tanto IVU como hipercalciuria (prelitiasis) de origen genético, planteamos si la historia familiar de urolitiasis es más frecuente en niños con IVU causada por E. coli. Secundariamente, planteamos si las cicatrices renales son más frecuentes en niños con prelitiasis. Material y métodos: Estudio ambispectivo con datos de 104 pacientes (40 masculinos y 64 femeninos) seguidos tras haber sido diagnosticados, al menos una vez, de IVU por E. coli. Se preguntó por la existencia de urolitiasis en familiares (primer y segundo grado). En 80 pacientes se determinó la eliminación urinaria de calcio y citrato. Resultados: En toda la muestra, la historia familiar de urolitiasis fue positiva en una frecuencia significativamente mayor de estos niños (n = 71; 68,3%) que en la población de control del mismo área (el 29,7% según datos previos publicados). La frecuencia de prelitiasis en niños con IVU fue del 47,5% (38/80). Se observó asociación entre prelitiasis tanto con la historia familiar de urolitiasis (p = 0,030) como con el reflujo vesicoureteral (p = 0,034). Además, los pacientes que desarrollaron cicatrices renales tenían más prelitiasis (OR 5,3; p = 0,033). Conclusiones: La frecuencia de historia familiar de urolitiasis en niños con IVU causada por E. coli es muy alta. Basándonos en nuestros resultados, sugerimos la hipótesis de que la predisposición a litiasis involucra una defensa alterada contra E. coli y, consecuentemente, una mayor posibilidad de cicatrices renales.
