Persistencia mayor a tres meses de tasa de filtrado glomerular disminuida y de marcadores de daño renal en una muestra de estudiantes de bioquímica de la Universidad Nacional del Litoral (Santa Fe, Argentina). 2014-2015

Introduction: Early stages of chronic kidney disease (CKD) are asymptomatic and patients may ignore their condition or discover it in a routine medical consultation or because of the consultation about other disease. CKD high global prevalence is accepted. Reliable data is needed to provide evidence and knowledge about the disease in the region. Methods: Descriptive study. 81 students. Period May 2014 to December 2015. Glomerular Filtration Rate, GFR, was estimated by CKD-EPI and creatinine clearance. Kidney damage was determined in 1st morning urine: test strip and urinary sediment and proteinuria. Students with GFR 150 mg/24 h; 8.6% hematuria and 1.2% cylindruria, isolated or combined with GFR<60 ml/min/1.73m2 and 1.2% had GFR <60 ml/min/1.73m2. At 3 months reevaluation persistent findings were seen in 11.2% of the subjects studied. Conclusions: The high proportion of apparently healthy young people with persistent impaired renal function or markers of renal damage in a follow-up greater than 3 months provides an evidence of the magnitude of the CKD problem.
