It is proved that HUS in children is the cause of the formation and progression of renal dysfunction with the formation of CKD. At the same time, the outcomes of HUS in childhood remain insufficiently studied. Purpose. To establish the outcomes of hemolytic-uremic syndrome in children and to develop an algorithm for their prediction.Results. Seasonality is established (May and June) HUS in children, an increase in the incidence rate. In the structure of HUS in children of the Orenburg region, STEC-HUS prevails (96.5 %), more often (68.6 %) in infants and young children. Chronic kidney diseases associated with HUS are characterized by a violation of the structure of the kidneys, a decrease in intrarenal hemodynamics, increased blood pressure, microalbuminuria, tubular dysfunction and a decrease in glomerular filtration rate in combination with an increase in the level of endothelin-1 blood, cystatin From urine and blood, uNGAL. An increase in endothelin-1 in blood, cystatin From urine and blood, uNGAL correlates with the level of increased blood pressure, a decrease in intrarenal hemodynamics, GFR and tubular dysfunction and are pathogenetic criteria for kidney damage in HUS convalescent children. Discussion. Clinical and pathogenetic markers of the formation of CKD have been established: an increase in the level of blood EТ-1, blood cystatin, urine lipocalin in combination with arterial hypertension, a decrease in GFR and intrarenal hemodynamics, an increase in tubular dysfunction and the level of microalbuminuria. Conclusion. The outcomes of HUS in children are- favorable (recovery); unfavorable (formation of chronic kidney pathology): TIBP, occurring with isolated urinary syndrome; nephropathies with isolated prenephrotic proteinuria; chronic kidney disease; fatal outcome. The developed «Algorithm for predicting chronic kidney damage in children with HUS convalescents», «Method for predicting tubulo-interstitial kidney disease in children associated with hemolytic-uremic syndrome», allow optimizing the early diagnosis of chronic kidney pathology in children after HUS, contribute to the timely appointment of preventive measures to prevent the progression of renal dysfunction and is recommended for use in the practice of pediatricians, nephrologists.
