RENOPROPHYLAXIS IN SECONDARY CHRONIC PYELONEPHRITIS IN CHILDREN
Abstract: The study involved 85 children with chronic pyelonephritis on the background of dysmetabolic disorders of the oxaluria type at the age of 4 to 15 years. Patients were conditionally divided into 4 groups depending on the method of treatment. In the period of exacerbation of chronic dismetabolic (oxalate) pyelonephritis, disturbances of partial kidney functions were noted in patients: a decrease in the glomerular filtration rate, osmolarity of urine, daily diuresis; processes of endotoxicosis: a significant reduction in the total albumin concentration, effective albumin concentration, the binding capacity of albumin in the blood plasma, and an increase in the total albumin concentration, of medium-molecular peptides in the urine.
Keywords: chronic pyelonephritis, children, lymphotropic.
Introduction. Preventive medicine is topical and in Objective: to develop the principles of secondary pre-
many ways discourteous. In connection with the high vention ofchronic dysmetabolic pyelonephritis in children.
frequency of chronic kidney disease in children, the prevention of their exacerbations is gaining increasing recognition [3, 12]. The most prevalent in the structure of nephropathy now are kidney lesions of metabolic origin, which constitute the majority - 40.0% of all kidney diseases in children, and in young children up to 71.6% [4, 11]. In the practice of a pediatrician, signs of metabolic disturbances in the urine are found in every third child [1; 2; 13]. In Uzbekistan, in the structure of dismetabolic nephropathy in children, oxalate crystalluria is the most common, accounting for 68-71% of all metabolic disorders [5; 6]. Dysmetabolic disorders are one of the leading predisposing factors to the recurrence and progression of chronic pyelonephritis in children [8; 14]. At the basis of the pathogenesis of dismetabolic nephropathies, especially those caused by genetic factors, there are metabolic processes ofinterstitium, glomerulus and renal tubules [2; 7]. And therefore, the consequence of renoprophylaxis should be the prevention of marked glomerular sclerosis and tubulointerstitial fibrosis, which is the basis of chronic renal failure [3, 9, 15]. In the case of dismetabolic chronic pyelonephritis, the measures should be directed to reduce the concentration of nephrotoxic salts leading to ischemia, edema and sclerosing of the kidney [5; 10; 16].
The study involved 85 children with chronic pyelonephritis on the background of dysmetabolic disorders of the oxaluria type at the age of 4 to 15 years. Patients were conditionally divided into 4 groups depending on the method of treatment. Group I included 48 children who received conventional therapy (in the first three days, it is usually i\m cefotaxime, after the results ofbacteriological study - antibacterial drug, depending on the sensitivity of the pathogen). Group II consisted of 37 patients who received antibiotics in a lymphotropic way, that is, regional lymphotropic antibacterial therapy (RLAT) was performed in combination with 0.5% euphylln electro-phoresis. The patients of all studied groups received a copious drink and followed a diet used for oxaluria. The control group consisted of 30 practically healthy peers.
All examined patients under went genealogical pedigree analysis in order to establish the fact of hereditary burden. Studies of indices of endogenous intoxication and functional state of the kidneys were performed in all children before and after treatment. Glomerular filtration of the kidneys was determined by the clearance of endogenous creatinine (Van Slayke), osmolarity of urine by cryoscopic method on OMK apparatus A - 1 C - 01, oxalate by NV. Dmitrieva (1966) method.
The severity of endotoxicosis was assessed by the total concentration of albumin (TCA) and the effective concentration of albumin (ECA) in the blood plasma, and also TCA in the urine taking into account the binding capacity of albumin (BCA) in the description of P. E. Kiseleva [6]. The determination of the level of the average molecular peptides (AMP) was carried out according to the method of I. I. Zhadenova and co-authors
was carried out using computer statistical programs Excel. In the study of indices of endogenous intoxication, depending on the method of treatment of chronic dys-metabolic pyelonephritis, it was revealed: in children receiving standard therapy (group I), before discharge from hospital, the level of TCA, ECA, BCA in blood plasma, as well as TAC and AMP in urine remained practically unchanged (Pi > 0.1) (Table 1, 2).

The obtained results allowed to recommend complex treatment (RLAT + electrophoresis with 0.5% of euphyllin) of chronic dismetabolic pyelonephritis for the prevention of frequent relapses, development of renal failure, that is, to use as a method of renoprophylaxis.
Сonclusions. 1. In the period of exacerbation of chronic dismetabolic (oxalate) pyelonephritis, disturbances of partial kidney functions were noted in patients: a decrease in the glomerular filtration rate, osmolarity of urine, daily diuresis; processes of en-dotoxicosis: a significant reduction in the total albu-
min concentration, effective albumin concentration, the binding capacity of albumin in the blood plasma, and an increase in the total albumin concentration, of medium-molecular peptides in the urine. 2. The use of complex treatment: RLAT + electrophoresis with 0.5% of eufillin in CCP is the most acceptable method of therapy, which leads to recovery of daily diuresis, has a positive effect on the level of oxaluria, the functional state of the kidneys and the indices of endogenous intoxication: the level of TCA, ECA, BCA in blood plasma and TCA, AMP in urine.
