The excretion of renal prostaglandins (PGE, PGF2 alpha, 6-keto-PGE1 alpha and TKB2) was studied in 45 children with chronic obstructive pyelonephritis in the presence of vesicoureteral reflux with account for the disease stage (partial remission--group I; total clinical and laboratory remission--group II) in various periods of surgical corrections of the impaired urodynamics in the area of vesicoureteral segments (in the early postoperative period of 12-14 days after the surgery; in the follow-up period of 6-12 months after the surgery). Preoperative observation of Group I children revealed a significant decrease in urinary PGF2 alpha excretion in the presence of an increase in the circadian TKB2 and 6-keto-PGF1 alpha excretion, whereas the patients from Group II who had normal levels of TKB2 and 6-keto-PGF1 alpha excretion, the levels of PGE and PGF2 alpha were lowered. The retention of sodium was documented in both groups. There was a total recovery of renal sodium and water excretion 6-12 months after the surgery. Children without the urinary syndrome (group II) demonstrated normalization of all secreted prostanoids, whereas in those with pronounced severity of pyelonephritis (group I), the excretion of sodium and diuresis were likely to be provided by hyperproduction of vasodilating sodium and diuretic PGE.

This pilot study was undertaken to characterise the pharmacokinetics, pharmacodynamics and potential clinical efficacy of levofloxacin 750 mg once daily for 5 days for treatment of women with acute uncomplicated pyelonephritis. Four women diagnosed with acute pyelonephritis were enrolled. Following pre-therapy specimen collection, an initial oral dose of 750 mg levofloxacin was administered. The mean pharmacokinetic parameters for the first dose were: maximum serum concentration (C(max)) 12.5+/-4.7 mg/L (range 5.6-16.0mg/L) (fC(max) 8.8+/-3.3, where f indicates the levofloxacin free or non-protein-bound fraction), area under the serum concentration-time curve (AUC) 85.4+/-14.1 mgh/L (range 66.2-96.8 mgh/L) (fAUC 59.8+/-9.9) and serum half-life (t(1/2)) 6.7+/-0.5h. Mean urine concentrations were 88.0+/-100mg/L at the 0-3 h collection, 307+/-143 mg/L at 3-6 h, 170+/-107 mg/L at 6-12 h and 85+/-8 mg/L at 12-24 h. Mean levofloxacin serum pharmacodynamics for infecting Escherichia coli were: C(max)/minimum inhibitory concentration (MIC) 323+/-185(fC(max)/MIC 226+/-129); and AUC/MIC 2339+/-830(fAUC/MIC 1647+/-579). Mean urine levofloxacin concentration/MIC ratios were: 900+/-1389 for 0-3 h, 12100+/-4950 for 3-6 h, 5922+/-3912 for 6-12 h and 2233+/-1037 for 12-24 h. Levofloxacin eradicated E. coli from the urine by 3-6 h after the first dose. Levofloxacin 750 mg once daily for 5 days has pharmacodynamics that support further evaluation of this regimen for treatment of women with acute uncomplicated pyelonephritis.

The kidneys of the patients with purulent pyelonephritis (PP) undergo anatomic and functional alterations. The latter may be irreversible in some cases. The severity of the above alterations depends on PP form, choice and time of treatment. Our study included 84 patients who had PP at the age of 15 to 70 years. Primary PP was detected in 47 (56%) patients, secondary--in 37 (44%) patients. Open surgery was performed in 18 patients (group 1), transcutaneous drainage was used in 38 patients (group 2), conservative treatment was conducted in 28 patients (group 3). Comparison of dynamic nephroscintigraphic findings showed that recovery of renal function in groups 2 and 3 lasted 6-12 months versus 60-84 months in group 1. The degree of the renal function recovery depends on the PP form, age of the patient, duration of the disease, virulence of the causing agent, comorbid pathology, immune status, method of treatment. This was confirmed by the data of complex radionuclide examination. Long term complications, for instance, progress of arterial hypertension (41% cases) and chronic pyelonephritis (44% cases) were observed more frequently and earlier in patients after open operations.

Our study prospects of urovaxom in improvement of efficacy and prevention of recurrent urogenital infection. One capsule of oral vaccine uro-vaxom was given daily for a month to 127 patients: 23 males with chronic bacterial prostatitis/urethroprostatitis, 75 females with chronic cystitis, 29 females with urolithiasis complicated with secondary chronic pyelonephritis. Control examination was made each two months for a year. In signs of inflammation the patients received one more course of uro-vaxom for a month. It was followed by control examinations each three month for a year. We observed a 6-12 month "cold" period after one course of uro-vaxom in 86.7% patients. After the second course of immunoprophylaxis recurrent urogenital infection occurred 8 times less often. Thus, immunoprophylaxis of urogenital infection with oral vaccine uro-vaxom is highly effective, is well tolerated and, therefore, must enter the standards of medical care for patients with urogenital infection.
