Abstract: 121 young children with pneumonia with dysmetabolic nephropathy, as well as 20 children with pneumonia with urinary syndrome, were studied. For these children, glomerular function was assessed by the clearance of endogenous formation, ammonia, titratable acidity, osmolarity of urine, and metabolites (oxalates, urates, uric acid). In children with pneumonia with dysmetabolic nephropathy changes in kidney partial functions, structural and functional states of erythrocyte cytomembrane as well as strengthening of lipid peroxidation were observed. In this regard, metabolic corrective therapy for these children was recommended.
