Abstract
BackgroundHaving a first- or second-degree relative with chronic kidney disease (CKD) has been reported as a risk factor for CKD development. The aim of the study was to determine the prevalence of CKD in children with a first- or second-degree relative undergoing renal replacement therapy (hemodialysis or renal transplant). MethodsA screening study was performed in asymptomatic children with a family history of CKD in a first- or second-degree relative undergoing renal replacement therapy. Informed consent was obtained in all cases. A clinical examination was performed. Blood and urine samples were obtained for serum creatinine, serum electrolytes, urinalysis, and microalbumin/creatinine ratio. ResultsThere were 45 subjects included with a median age of 9.6 years; 24 (53%) were male. Urinary abnormality/CKD was observed in 11 subjects (24.4%). The most common urinary abnormalities were hematuria (6/11) and microalbuminuria (4/11). Stage 2 CKD was found in seven subjects and four subjects with stage 1 CKD. ConclusionsThe study of families of patients undergoing renal replacement therapy is useful to identify children in early stages of kidney disease.
