Patients with secondary pyelonephritis have a high risk of developing chronic renal failure and a decline in the quality of life already in childhood. This pathology is prone to chronization, recurrence and progression with the formation of nephrosclerosis and the development of CRF, leading to disability of the body and requiring extraordinary interventions. Annually in the world among children it is fixed about 50 million cases of infection of urinary ways. In an open, prospective comparative study, the results of the analysis of the outcomes of the therapeutic and prophylactic efficacy of various therapies are presented in 85 children aged 4-15 years with chronic dysmetabolic pyelonephritis. Objective: to develop the principles of secondary prevention of chronic dysmetabolic pyelonephritis in children. Patients were divided into 2 groups depending on the method of treatment. 1 group consisted of 48 patients who used conventional methods of treatment. Group 2 consisted of 37 patients with children who received complex therapy: regional lymphotropic antibiotic therapy + electrophoresis with 0.5% euphillin. The results of our studies showed that after the conventional treatment there was no positive dynamics of the studied indicators of the functional state of the kidneys. A comparative assessment of the results of the study of the functional state of the kidneys and indices of endogenous intoxication showed a high efficiency of the combined use of regional lymphotropic antibiotic therapy + electrophoresis with euphyllin. Complex treatment, recommended by the authors, promotes renoprophylaxis: prevention of frequent recurrence of the disease and development of renal failure.

The authors present the results of follow-up observations of children that had undergone neonatal nephropathy. A follow-up observation revealed newborns from mothers with chronic kidney diseases are at risk for the development of neonatal nephropathies. The long-term positive results of the examination of children who underwent neonatal nephropathy and received a course of anti-relapse treatment proved the effectiveness of renal protection.

Introduction. Pneumonia remains an acute problem not only in pulmonology, but also in pediatrics in general. The prognosis of neonatal pneumonia depends on the perinatal period course. In this case, the predictor of risk is the state of the brain, the main organ that regulates the whole organism’s work. The most available method for brain condition’ assessing in children of the first year of life is neurosonography. The ability of the brain to restore impaired functions is very high during infancy. Early diagnosis and treatment of the correlation relationships’ violations of brain structures in pneumonia of newborns will help prevent an unfavorable outcome of the disease.Aim. Тo study the features of the correlation relationships of structural changes of the brain in pneumonia in infants.Materials and methods. Neurosonographic study was carried out at 57 children: with pneumonia without concomitant diseases (17 children – group 1), against the background of: perinatal lesions of the nervous system (group 17 – 2), jaundice (group 16 – 3), congenital heart defects (group 7 – 4) with SonoScape 1000 apparatus. Neurosonography and echocardiography were performed with a sector transducer with a frequency of 7.5 MHz. All 377 correlations were assessed for 25 studied parameters.Results. The study of correlations revealed the predominant participation of the sections of the right lateral ventricle and the flow system of the brain. The severity of synchronous functional activity (the number of correlations) characterizes the degree of functional tension, stress reaction of the studied structural part and has a relatively greater risk of depletion and, as a consequence, a greater likelihood of destructuring. In the process of adaptation and the formation of compensatory mechanisms, the predominant functional load falls on the right parts of the brain (right lateral ventricle).Conclusions. The most pronounced changes in brain structures during neurosonography were found in infants with pneumonia, which developed against the background of neonatal jaundice and congenital heart defects. In all groups of patients with neonatal pneumonia, correlations were found between the parameters of the structure and flow system of the brain, laboratory parameters indicating the tension of the compensatory mechanisms of organs and systems. The revealed changes characterized the developing of the hydrocephalus in the absence of pathognomonic clinical and neurological symptoms in patients.
