Prediction of cardiovascular complications and progression of renal failure in pediatric patients with chronic kidney disease according to NKF-K/DOQI (2002) and KDIGO (2012) classifications

Abstract

Chronic kidney disease in pediatric and adult patients is an overarching global problem. Stratification of chronic kidney disease C1–5 severity by classifications of the National Kidney Foundation’s Kidney Disease Outcomes Quality Initiative (NKF-K/DOQI) (2002) and Kidney Disease: Improving Global Outcomes (KDIGO) (2012) carried out in pediatric patients over the age of 2 years old, taking into account the low glomerular filtration rate at the age of 0 to 2 years. Differences were found in the prognosis of cardiovascular complications and the progression of renal failure in adult patients with chronic kidney disease at stages С3а and C3b according to KDIGO (2012). The literature data demonstrate different risks of cardiovascular complications and progression of renal functions by stages of chronic kidney disease in accordance with the NKF-K/DOQI (2002) and KDIGO (2012) classifications in pediatric patients. The results indicate that children with chronic kidney disease in the pre-dialysis stages C2–4 form a high-risk group, while those on C4–5 dialysis form a group of very high risk of cardiovascular complications.
