RESUMO
INTRODUCTION: Treatment of pyelonephritis in children should be combined, long-term and individual-based. The success of the therapy in children largely depends on the prompt appointment and the correct choice of antimicrobial therapy. AIM: To evaluate the efficiency of the dietary supplement "Cystenium II" in a group of children aged 7 to 14 years with a diagnosis of acute and chronic recurrent pyelonephritis in the acute phase. MATERIALS AND METHODS: A total of 60 children aged 7 to 14 years with a diagnosis of acute or chronic recurrent pyelonephritis in the acute stage were included in the study. The clinical group consisted of 30 patients (mean age 12.1+/-1.8 years), while the control group included 30 patients of mean age 11.2+/-1.7 years. In the control group patients received only standard antibiotic therapy, while in the clinical group it was combined with a dietary supplement "Cystenium II" 1 tablet 2 times a day with meals for 14 days. After the course of antibacterial treatment, the children in the clinical group continued to take the studied dietary supplement for another 14 days in order to prevent the recurrence of pyelonephritis. The results of treatment (patient's condition, presence of pain, dysuria, fever) were assessed on the 3rd, 7th, 14th day, 1 and 6 months after the start of treatment. A urinalysis was performed at the baseline, on the 7th and 14th days, as well as after 1 and 6 months. Urine culture was performed before and after antibiotic therapy at the baseline, on the 14th day, 1 and 6 months after the start of treatment. RESULTS: The main indicators of urinalysis (leukocytes, red blood cells, protein) returned to normal values in 26 (86.7%) patients of the clinical group and in 23 (76.7%) patients of the control group on the 7th day after the start of treatment. At the completion of the basic therapy (after 14 days) normal clinical parameters (absence of leukocyturia, microhematuria, proteinuria) were observed in all patients of the clinical group and in 28 (93.3%) patients of the control group. After a month of follow-up, the disturbances in urinalysis (leukocytes, red blood cells, protein) in the control group were again seen in 3 (10%) patients, as well as after 6 months. However, in the clinical group all patients had normal urinalysis (absence of leukocyturia, microhematuria, proteinuria) after 1 month and only in 1 (3.3%) case leukocyturia, as well as an increase in the number of red blood cells and protein was detected by 6 months. DISCUSSION: According to our results, the use of dietary supplements "Cystenium II" (manufactured by Akvion, Russia), due to the constituents of D-mannose (450 mg), cranberry fruit extract with a standardized activity of 500 mg (36 mg of proanthocyanidins) and vitamin C (60 mg), may cause anti-inflammatory and anti-adhesive effects (resolving of leukocyturia and bacteriuria). This allows to use the dietary supplement Cystenium II in children from 7 years of age in the combination therapy of acute pyelonephritis, as well as exacerbation of chronic pyelonephritis. The obtained results showed a high overall therapeutic efficacy of combination therapy using Cystenium II after 6 months from the start of treatment (relapse in 1 patient), in contrast to the control group (relapse in 6 patients). CONCLUSIONS: the use of dietary supplement "Cystenium II" allowed to reduce the number of repeated courses of antibiotic therapy in children during 6 months of follow-up and, most likely, reduced the frequency of development of chronic pyelonephritis after an acute inflammation. Therefore, the wide clinical use of dietary supplements "Cystenium II" for the combined treatment of acute and exacerbation of chronic pyelonephritis in children older than 7 years seems to be very reasonable.

Current international and Russian clinical guidelines recommend treating asymptomatic bacteriuria in pregnancy to prevent acute gestational pyelonephritis. At the same time, the growing resistance of uropathogens and the risks associated with antibiotic therapy in pregnancy dictate the need to limit the use of antibiotics and seek alternative approaches to antibacterial therapy. MATERIALS AND METHODS: A retrospective analysis was performed on 60 pregnant women who received either a standard antibiotic regimen (n=32) or the herbal preparation Canephron N (n=28). The primary outcomes were the incidence of symptomatic infections (cystitis or pyelonephritis), premature birth and low birth weight delivery, and incidence of persistent/recurrent bacteriuria. RESULTS: In the group of antibiotic therapy, one patient developed cystitis and three had pyelonephritis; in the Canephron N group, cystitis occurred in one patient, no pyelonephritis cases were observed. Among the whole study cohort (n=60), the incidence of symptomatic infections and pyelonephritis was 8.3 and 5.0%, respectively. The incidence of symptomatic infections (cystitis, pyelonephritis) did not differ statistically significantly between the study groups (p=0.2157). There were three and one premature births in the group of antibiotic therapy and the Canephron N group, respectively (p=0,373), and two low birth weight deliveries in each group (p=0.891). Recurrent bacteriuria was registered in 17 patients from the group of antibiotic therapy and in three in the Canephron N group (p=0.0006). CONCLUSIONS: The management of asymptomatic bacteriuria in pregnancy using Canephron N is not inferior to standard antibiotic therapy regarding the incidence of symptomatic infection, premature birth, and low birth weight delivery. Persistent/recurrent bacteriuria was more common in women receiving the antibiotic therapy.

PURPOSE: To compare postoperative complications in patients with or without preoperative immunonutrition before cystectomy. METHODS: A prospective, multicenter, pilot, case-control study was conducted during 6 months. Patients with 7-day preoperative immunonutrition were prospectively included and compared with a retrospective, matched control group without immunonutrition. Early complication rates and the length of hospital stay were analyzed. The bilateral type I error was <0.05; the power was 90%. Thirty patients in each group were required. RESULTS: Thirty patients were included in each group, on a comparable basis. In the immunonutrition group, fewer postoperative complications (40 vs. 76.7%; p = 0.008), less paralytic ileus at D7 (6.6 vs. 33.3%; p = 0.02), fewer infections (23.3 vs. 60%; p = 0.008), and in particular less pyelonephritis (16.7 vs. 46.7%; p = 0.03) occurred. Clavien's grades for complications were higher in the control group (p = 0.04). Mortality, pulmonary embolism, anastomotic fistulae, and wound dehiscence were similar between two groups. The length of stay was reduced by 3 days in the immunonutrition group. CONCLUSIONS: In this pilot case-control study, immunonutrition is associated with a decrease in postoperative complications, urinary tract infections, Clavien's grade for complications, and paralytic ileus in patients undergoing cystectomy for bladder cancer. Prospective randomized placebo control studies are needed to confirm these promising results.

The study of efficacy and safety of the drug vitaprost plus (rectal suppositories) in its use for prevention of infectious-inflammatory complications after transurethral resection (TUR) of the prostate for adenoma included 55 male surgical patients with prostatic adenoma (PA). The patients were randomized into two groups matched by age, symptoms and clinical data. The control group consisted of 20 patients (group 1), the study group--of 35 patients (group 2). TUR of the prostate was made in both groups, but patients of group 2 were given additional prophylactic treatment--vitaprost plus, one suppository before going to bed 2 days before surgery and for 8 days after TUR, the course lasted for 10 days. Postoperative blood and urine samples showed inflammatory changes more often in group 1, free of infection bacterial tests were more often in group 2. Renal microcirculation in group 1 after TUR evidenced for functional depression on perfusion intensity and renal ischemia and congestion. These changes persisted on postoperative day 8, being a potential cause of renal inflammation and ascending pyelonephritis. Group 2 patients exhibited insignificant postoperative microcirculatory disorders in the kidneys and were not registered on postoperative day 8. Infectious-inflammatory complications in group 1 patients were registered much more frequently than in group 2 patients. Thus, vitaprost plus can be recommended for prophylaxis of infectious-inflammatory complications of TUR in PA patients.

INTRODUCTION: Not only bacterial characteristics but also oxidative/nitrosative stress could play a significant role in renal parenchymal inflammatory processes in acute pyelonephritis (APN). This study was conducted to evaluate the effect of ozone therapy (OT), as an immunomodulator and antioxidant, on the renal function, morphology and biochemical parameters of oxidative stress in an experimental model of APN in rats. MATERIALS AND METHODS: Forty rats were divided equally into five groups as control, APN, APN + Antibiotic, APN + OT, and APN + Antibiotic + OT. APN was induced by 0.1 ml of freshly prepared Escherichia coli (ATCC 25922) solution containing 10(10) colony-forming unit/ml into the kidney. A control group was administered 0.1 ml of 0.9 % NaCl solution. Treatment was begun 72 h after bacterial inoculation. Control and APN groups were given 0.9% NaCl solution, APN + Antibiotic and APN + OT were given either antibiotic (ciprofloxacine 150 mg/kg intramuscular/twice daily) or OT. APN + Antibiotic + OT group was given both antibiotic and OT for five consecutive days. At the end of the seventh day, animals were killed via decapitation and trunk blood was collected. Both kidneys were harvested and one half of each kidney were immediately stored for antioxidant enzyme activity, tissue lipid peroxidation and protein carbonyl content. The remainder was fixed for histopathologic examination. RESULTS: E. coli-induced APN increased the renal glomerular and tubular dysfunction, oxidative stress parameters and antioxidant enzyme activities. Either antibiotherapy or OT markedly ameliorated renal dysfunction, the antioxidant status of the kidneys and histopathological injuries subjected to E. coli-induced APN. Interestingly, the combination of antibiotherapy and OT was much more effective than either of the treatment modalities alone. CONCLUSION: The combination of antibiotherapy and OT markedly ameliorated renal dysfunction and improved antioxidant status and histopathologic modalities in rats subjected to E. coli-induced APN than either antibiotherapy or OT treatment alone. Therefore, OT may be considered as an adjuvant therapy to classical antibiotherapy to prevent renal inflammation and fibrosis in APN.

Introducción: En la búsqueda de alternativas a la quimioprofilaxis antibiótica en la prevención de las infecciones urinarias (ITU) en el niño, hemos comenzado a utilizar un extracto de arándano rojo americano con 118 mg de proantocianidinas. Éstas inhiben la adherencia a la pared de la vía urinaria de Escherichia coli fimbriada tipo P. Objetivos: Observar la eficacia y la tolerancia de un extracto de arándanos en niños con ITU frecuentes. Material y métodos: Se seleccionan grupos de pacientes con ITU recidivantes frecuentes sin patología orgánica malformativa ni vejiga neuropática, litiasis o insuficiencia renal. El estudio observacional se efectuó durante 1 año en 62 niños de 5-17años de edad. Resultados: Se obtuvo un 100% de prevención de la pielonefritis aguda y un 92% de ausencia de infecciones sintomáticas. Conclusiones: Hemos observado una gran eficacia del producto, ausencia de efectos adversos y una muy buena aceptación por parte de los padres y los pacientes para realizar un tratamiento prolongado, así como una baja tasa de abandonos. Será necesario realizar estudios prospectivos, doble ciego, aleatorizados y controlados con placebo para poder establecer recomendaciones con un alto grado de evidencia (AU)
Introduction: In our search for alternatives to antibiotic chemoprophylaxis to prevent pediatric urinary infections, we have started to use a concentrated extract of North American red cranberries containing 118 mg of proanthocyanidins, the before mentioned inhibit the adherence of P-fimbriated Escherichia coli to the urinary tract wall. Objectives: To observe the effectiveness and tolerance of a concentrated extract of cranberries in children with frequent urinary tract infections. Material and methods: We selected groups of patients with frequently recurrent urinary infections, with no malformative systemic pathologies and either neuropathic bladder, lithiasis or renal failure. The observational study was conducted over one year in 62 children from 5 to 17 years old. Results: The results were quite satisfactory: 100% prevention of acute pyelonephritis, and 92% absence of symptomatic infections. Conclusions: We have been able to confirm the high effectiveness of the product, the absence of adverse effects, an excellent acceptance by the parents and patients regarding along-term treatment, and a very low rate of dropouts. Prospective double-blind randomized and placebo-controlled trials will be required in order to issue recommendations supported by a high degree of evidence (AU)

BACKGROUND: Serious infectious morbidity is high in preterm infants. Enteral supplementation of prebiotics may reduce the incidence of serious infections, especially infections related to the gastrointestinal tract. OBJECTIVE: The objective was to determine the effect of enteral supplementation of a prebiotic mixture consisting of neutral oligosaccharides ((SC)GOS/(LC)FOS) and acidic oligosaccharides (AOS) on serious infectious morbidity in preterm infants. DESIGN: In a randomized controlled trial, preterm infants (gestational age <32 wk and/or birth weight <1500 g) received enteral supplementation of 80% (SC)GOS/(LC)FOS and 20% AOS (1.5 g . kg(-1) . d(-1)) or placebo (maltodextrin) between days 3 and 30 of life. Serious infectious morbidity was defined as a culture positive for sepsis, meningitis, pyelonephritis, or pneumonia. The analysis was performed by intention-to-treat and per-protocol, defined as > or =50% supplementation dose during the study period. RESULTS: In total, 113 preterm infants were included. Baseline and nutritional characteristics were not different between groups. In the intention-to-treat analysis, the incidence of > or =1 serious infection, > or =1 serious endogenous infection, or > or =2 serious infectious episodes was not significantly different in the (SC)GOS/(LC)FOS/AOS-supplemented and placebo groups. In the per-protocol analysis, there was a trend toward a lower incidence of > or =1 serious endogenous infection and > or =2 serious infectious episodes in the (SC)GOS/(LC)FOS/AOS-supplemented group than in the placebo group (P = 0.09 and P = 0.07, respectively). CONCLUSIONS: Enteral supplementation of (SC)GOS/(LC)FOS/AOS does not significantly reduce the risk of serious infectious morbidity in preterm infants. However, there was a trend toward a lower incidence of serious infectious morbidity, especially for infections with endogenous bacteria. This finding suggests a possible beneficial effect that should be evaluated in a larger study. This trial was registered at isrctn.org as ISRCTN16211826.

The study of dietary supplement (biologically active additive) Prolit in 20 patients and 20 controls (mean age 44.0 +/- 13.8 years) hospitalized for urolithiasis, uncomplicated renal colic proved that Prolit use in combined therapy of urolithiasis effectively relieves pain syndrome (renal colic) and prevents its recurrence. Prolit has a pronounced anti-inflammatory and spasmolytic effects which prevent attacks of acute (chronic) pyelonephritis. Combined treatment of urolithiasis with Prolit addition has one more advantage over conventional therapy in evacuation of the concrements and elimination of urostasis, especially in small concrements (up to 1 cm) in the ureter.

Vesicoureteral reflux (VUR) is one of the most frequent diseases which leads to pyelonephritis and furthermore, renal damage. The treatment of VUR (surgical or endoscopic) remains a controversial topic. Autologous blood injection--autohemotherapy (AHT) is used in the endoscopic treatment of VUR. The aim of the research was the comparison of efficacy of AHT and conservative therapy in children with bilateral VUR grade III. 125 children were treated endoscopically. The results of the AHT were compared with the results of conservative treatment in 121 children with the same kind of disease. Complete disappearance of VUR after AHT was observed in 61.6% of children and in 59.5% after two years of medical treatment. These results were not significantly different (p > 0.73) in contrast to the results reached after one year of conservative therapy (p < 0.01). After the conservative treatment in 33.5% of kidneys reflux nephropathy (NR) was observed. In the group treated by AHT NR developed in 25.2% of kidneys. The frequency of NR was significantly higher in children after conservative treatment (p < 0.001). 29.8% of children after conservative therapy and 8% of children after AHT were operated. The results of research proved that usefulness of intravesical autohemotherapy in the treatment of VUR. The method was safe with a low quantity of complications. The efficacy of AHT in the elimination of bilateral high grade VUR was comparable to this reached after two years of conservative treatment.

OBJECTIVE: To investigate the relationship between chronic pyelonephritis (CPN) and immune function, and the therapeutic mechanism of Yishenkang granule (YSKG). METHODS: One hundred and twenty patients of CPN were divided into 3 groups randomly, the YSKG group (treated with YSKG), the control A group (treated with Sanjin tablet) and the control B group (treated with western medicine). Serum levels of immunoglobulin (Ig), complement 3 (C3), interleukin-2 (IL-2), peripheral T-lymphocyte subsets, and urinary secretory immunoglobulin A (sIgA) were determined before and after treatment with monoclonal antibody assay, agar diffusion method, radioimmunoassay (RIA), and radioimmuno-equilibrium method, and compared with normal control. RESULTS: There were disorders of T-lymphocyte subsets in CPN, lowering of serum Ig, C3 and urinary sIgA, and increase of blood IL-2 (P < 0.05 or P < 0.01). These abnormalities could be normalized after YSKG treatment. CONCLUSION: Functional disorders of cellular and humoral immunity exist in CPN patients of chronic stage, YSKG could correct the immune functional disorder, control the recurrence of CPN effectively and alleviate the immunopathological damage.

Renal scarring, which occurs following refluxing pyelonephritis, is considered to be involved in the development of reflux nephropathy. Prevention of renal scar formation requires immediate initiation of antimicrobial treatment; treatment delay results in renal scarring. We demonstrate that Ebselen, an antioxidant agent, given at a dose of 15 mg/kg twice a day prevents renal scarring in rats following direct renal parenchymal bacterial inoculation. In addition, using an ascending pyelonephritis model, which clinically resembles refluxing pyelonephritis in humans, we show that when initiation of antimicrobial treatment was delayed, coadministration of Ebselen prevents renal scar formation. These results show that Ebselen is effective in preventing renal scarring and suggest that the clinical use of this drug may prevent renal scar formation following pyelonephritis and progression to reflux nephropathy.

It has been shown in experimental animals that an ileorectal valve incorporated into the operation of uretero-ileosigmoidostomy cannot be relied upon to prevent ascending urinary tract infection. However, a colorectal valve, not previously described, has been effective in preventing the development of a metabolic acidosis in piglets in whom this method of urinary diversion has been carried out.
