OPTIMIZATION OF METHODS OF DIAGNOSTICS AND TREATMENT OF SECONDARY CHRONIC PYELONEPHRITIS IN CHILDREN
Abstract: The point finger of intersection of the XII rib and the outer edge of the long back muscle (m. Sacro-spinalis), was determined by the index finger of the left arm and that place was pre-treated with alcohol or iodine. The use of complex treatment: regional lymphotropic antibacterial therapy + vitamin A in chronic pyelonephritis is an effective method of therapy, which leads to the restoration of daily diuresis, has a positive effect on the level of oxaluria, the functional state of the kidneys and cytokine urine profile: IL-10, IL -1, IL-6, IL-8.

Objective: to evaluate the complex treatment of chronic pyelonephritis in children.
The study involved 177 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 2 groups depending on the method of treatment. Group I included 48 children who received conventional therapy (in the first three days, usually cefotaxime i/m, after the results of bacteriological study - antibacterial drug, depending on the sensitivity of the pathogen). Group II consisted of 37 patients who received antibiotics in a lym-photropic way, that is, RLAT method (regional lymphotropic antibacterial therapy) in combination with vitamin A.
Method: The point finger of intersection of the XII rib and the outer edge of the long back muscle (m. Sacrospinalis), was determined by the index finger of the left arm and that place was pre-treated with alcohol or iodine. Then, at this place, a thin needle puncture was performed and 0.25% solution of novocaine was administered as a lymphostimulator at the rate: 3-5 ml to children with a body weight of up to 16 kg, and 5-10 ml to ones with more than 16 kg, after 5-10 min an antibiotic (cefotaxime) was administered in an amount of1/3 of the daily age dose (ie, from the calculation of 50 mg / kg of body weight) [1].
Patients of both groups received a profuse drinking and were on a diet used for oxaluria. The control group consisted of 25 practically healthy children of the same age.
Genealogical analysis of pedigree was carried out to establish the fact of hereditary burden of all examined children. The indices of the urinary cytokine profile and the functional state of the kidneys were studied in all children before and after treatment. Glomerular filtration of the kidneys was determined by the clearance of endogenous creatinine (Van Slayke) and osmolarity of urine by cryoscopic method on OMK apparatus A - 1 C - 01, oxalate by NV. Dmitrieva (1966).
Commercial sets were used to measure interleukin lev-els-1, 6, 8, 10 in serum and urine in children with chronic pyelonephritis: CYTELISA-IL-1b, CYTELISA-IL-1, CY-TELISA-IL-6, CYTELISA-IL-8, CYTELISA - IL-10 (CY-TIMMUNE, USA). Their application is based on the "sandwich" method of solid state enzyme-linked immunosorbent analysis (ELISA-enzyme-linked immunosorbent assay), the principle ofwhich is the qualitative and quantitative determination of the antigen under study by its layer-by-layer binding to antibodies specific for it. Mathematical processing of the obtained results was carried out using computer statistical programs Excel.
When studying the parameters of the cytokine profile of urine, depending on the method of treatment of chronic pyelonephritis, it was revealed: in children receiving standard therapy (group I), before discharge from hospital, the level of IL-1, IL-6, IL-8, IL-10 in urine was almost not changed (Pj > 0.1) (Table 1).

More pronounced changes in the cytokine urine profile in patients were revealed on the background of the use of RLAT in combination with vitamin A (group II). Our study showed that the "average" concentration of IL-1, IL-6, IL-8 in urine in children of the 2nd group after treatment with 4th scheme had a more positive downward trend, compared to group 1 (Table 1).
After treatment of group II of patients, the level of IL-10 had a relatively high tendency toward normalization (Px < 0.01, P2 > 0.01), compared to group 1 (Px > 0.1) (Table 1).
After the therapy in both groups, we recorded a relatively high tendency to normalize the concentration of cytokines: IL-1, IL-6, IL-8, IL-10 in urine in children of group 2, which indicates the advantage of the 4th scheme of treatment.
Analyzing the state of kidney function in the examined patients who received traditional treatment, there was an improvement in the indices, but the difference was statistically unreliable (Px > 0.1). In Group II patients, after the treatment, there was a significant increase in the clearance of
endogenous creatinine (Px < 0.001), urine osmolality (Px < < 0.001), daily diuresis (Px < 0.001), oxaluria (Px < 0.001) compared with pre-treatment and post-treatment using conventional treatment of children of clinical group I (P2 < 0.001) (Table 2).

The obtained results allowed to recommend complex treatment (RLAT + vitamin A) of chronic pyelonephritis for the prevention of frequent relapses, development of renal failure, that is, to use at as a method of renoprophylaxis.
Conclusions. 1. In the period of exacerbation of chronic (oxalate) pyelonephritis, damages to partial functions of the kidneys were noted in patients: a decrease in the glomerular filtration rate, osmolarity of urine, daily diuresis; immune dis-
orders: a significant decrease in IL-10 and an increase in IL-1, IL-6, IL-8 in urine. 2. The use of complex treatment: regional lymphotropic antibacterial therapy + vitamin A in chronic pyelonephritis is an effective method of therapy, which leads to the restoration of daily diuresis, has a positive effect on the level of oxaluria, the functional state of the kidneys and cytokine urine profile: IL-10, IL-1, IL-6, IL-8.
