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.

The results of the treatment of 47 babies treated with the immunocorrecting drugs (t-activin, levamisole, sodium nucleinate, prodigiozan, lysozyme) together with antimicrobial remedies are described. The babies were selected from 120 patients suffering from pyelonephritis. Indications for use of the immunomodulators included the deficiency of the T component of immunity, of phagocytosis and, more rarely, of B lymphocytes, an unfavourable premorbed condition, severe lingering disease course as well as low efficacy of antibacterial therapy. Two control groups consisted of 120 patients who were not given the immunocorrecting remedies and 30 normal children of the first year of life. The immunostimulation therapy minimized the duration of the active phase of pyelonephritis, decreasing the rate of relapses and the probability that the disease may progress to a chronic course. The positive influence of the above drugs on the clinical picture of pyelonephritis enabled the duration of antibacterial therapy, the dosage and the frequency of antibiotic use to be reduced. The favourable outcome of pyelonephritis was followed by gradual normalization of the immunological parameters.

We investigated the relationship between urinary prostaglandin E2 (UPGE2), kallikrein (UKal), graft function and complications after renal transplantation in 11 patients. Grafts of 9 patients were from living-related donors (LRD), and other 2 patients were from a cadaveric donor (CAD). UPGE2 was measured by the radio immunoassay, and UKal was measured by the amidolytic method using Pro-Phe-Arg-MCA. The results were as follows. 1. In 5 of 6 patients from LRD without acute rejection episode (ARE), both UPGE2 and UKAL were within normal and/or slightly less than normal. UKal values of the other patient were high in his donor. 2. In 2 of 3 recipients from LRD who experienced ARE, UKal increased prior to ARE. UPGE2 also increased at the time of ARE, but it showed a periodic rise in the stable condition. 3. In 1 of 2 recipients from CAD, UKal exhibited a transient elevation at the time of acute tubular necrosis (ATN) and pyelonephritis while UPGE2 was low. In another recipient, UKal was almost within normal range at the time of ATN, and UPGE2 showed a periodic rise. 4. A significant correlation was seen between UKal, UPGE2 and UAld in the recipients from LRD without ARE (except 1 patient who showed high UKal values). However, the correlation was blurred inclusive of values in the patients who experienced ARE or other complications. There was no relationship between UKal, UPGE2, creatinine clearance, urine volume and urinary sodium. 5. Soybean trypsin inhibitor (STI) was used for the confirmation of specificity of the amidolytic method.(ABSTRACT TRUNCATED AT 250 WORDS)

The paper presented the experience in the prevention of infectious complications during the renal surgery developed both in the organ operated on (acute postsurgical pyelonephritis) and in the surgical wound later. The package of prophylactic measures was employed in 48 patients operated on for the diseases of kidneys and urinary tract (nephrolithiasis predominantly). It included aseptic, antiseptic techniques, antibacterial treatment and preventive treatment in the pre-, intra- and postoperative periods, as well as intraoperative irrigation of the wound with antiseptic solutions and postoperative local therapy. Antibacterial prophylaxis was started 3-5 days or at night before the indicated surgery. Antibiotics were administered only after a careful adjustment of the dosage. Their intravenous (mainly) injections were performed under the effect of preliminary anesthetics. Clinical materials for microbiological and pharmacokinetic monitoring were being taken during the operation. Sodium chloride solution was electrolyzed and the obtained sodium hypochloride was used for the sanation of pyogangrenous foci. Patients with pyodestructive renal lesions developed in the presence of active chronic or acute pyelonephritis and the drainage of the urinary tract underwent 5-7-day antibacterial therapy. The aforementioned preventive measures allowed the authors to gain a significant reduction in the incidence of postoperative pyelonephritis (from 94.2 to 31.2 per cent) and wound infection (from 19.2 to 8.3 per cent), as well as bacteremia (from 32.3 to 5.4). Postsurgical complications (acute pyelonephritis and wound infection), if appeared, ran a relatively favorable course and were cured 3-5 days later. Uroseptic conditions were not observed.

Diagnostic potentialities of the crystallo-optic++ analysis of cupric chloride crystallographs++ were studied in 76 children with pyelonephritis and in 50 children with glomerulonephritis. The structural and morphological characteristics of cupric chloride crystallization under the influence of the urine from children with pyelo- and glomerulonephritis may serve as the additional differential-diagnostic signs of the diseases. The use of raster electron microscopy widens the diagnostic potentialities of the crystallographic method. Different dimensions of the little crystals formed as a result of isomorphic replacement of copper atoms by potassium ions (and, possibly, by sodium ions) and in the presence of urea and creatinine underlie the differences in cupric chloride crystallographs.

Ifosfamide (isophosphamide) and mesna (2-mercaptoethane sodium sulfonate) were administered intravenously at monthly intervals to 46 patients with advanced epithelial ovarian carcinoma refractory to or recurrent after cisplatin-containing combination chemotherapy. Initially, ifosfamide was given as 1.5 g/m2/d x 5 days and mesna as 300 mg/m2 every 4 hours for three doses following ifosfamide, but the initial dose of ifosfamide was reduced to 1.2 g/m2 because of toxicity. Four of the patients initially entered were found to be ineligible: two who had had more than one prior chemotherapy regimen and two who did not have ovarian primaries. One patient received an inadequate trial and four patients had discontinuation of therapy because of toxicity, leaving 41 evaluable for response. Three patients (7.0%) had complete responses and five (13.0%) had partial responses for an overall response rate of 20.0%. Response duration ranged from 2.1 to 20.3 + months with a median of 6.9 + months. Two patients died of renal failure, one of whom had no known renal disease and received 1.5 g/m2/d x 5 days ifosfamide. The second patient received the 1.2 g/m2 dose and was found to have chronic pyelonephritis and pyonephrosis at autopsy. Gynecologic Oncology Group (GOG) grade 3 or 4 granulocytopenia was seen in eight (19.5%), grade 3 or 4 thrombocytopenia in four (9.8%), and grade 3 or 4 neurotoxicity in six (14.6%) of the 41 patients evaluable for toxicity. Ifosfamide/mesna is active in epithelial ovarian cancer. GOG trials in untreated patients are being initiated and toxicity is being evaluated.

Pathophysiological characteristics and long-term prognosis were studied retrospectively in 69 malignant hypertensives associated with grade III or IV retinopathy and the diastolic blood pressure greater than 120 mmHg. Thirty three (48%) cases had essential hypertension (EHT) as the underlying disease, 26 (38%) as chronic glomerulonephritis (CGN), and the remaining 10 (14%) as others including chronic pyelonephritis, renovascular hypertension, hydronephrosis, multiple calyceal diverticula, and unknown original disease. The role of the renin-angiotensin system in malignant hypertension was investigated by measuring plasma renin activity (PRA) and determining the blood pressure response to angiotensin (ANG)II antagonist, (Sar1, Ile8) ANG II. Basal PRA was significantly higher in the EHT group than the CGN group, and the ANG II antagonist-induced reduction of blood pressure was only evident in the former group. The regression analysis revealed that PRA was linearly correlated with both mean blood pressure (MBP) and serum creatinine prior to antihypertensive treatment in the EHT group but not in CGN patients, although there was inverse correlation between PRA and serum sodium in both groups. Therefore, the renin-angiotensin system seems to play a significant role in elevating blood pressure and deteriorating renal function in malignant hypertension developed from EHT, while it is less important in that from CGN. The 5-year survival rate was 90% in total 69 patients with malignant hypertension, while the 5-year renal survival rate defined as the probability of surviving without maintenance hemodialysis was 37%, indicating that the treatment with hemodialysis as well as antihypertensive drug therapy contributed to an improvement of prognosis of malignant hypertension. The EHT group showed a poor prognosis for life compared with the CGN group, while in the latter group most patients rapidly developed endstage renal failure. Although the pretreatment serum creatinine levels were matched, the renal function more rapidly deteriorated after development of malignant hypertension in the CGN group than did in the EHT group, indicating renal survival rate to be shorter in the former group. Hence, underlying diseases may affect the long-term prognosis of malignant hypertension. The results obtained from this study suggest that the pathophysiological characteristics of malignant hypertension are different and its long-term prognosis is varied by underlying diseases such as EHT and CGN.

Lipid peroxidation (LPO) and transmembranous transportation were analysed in the red cells of 56 patients with chronic pyelonephritis with regard to the pathologic changes in the membranes. LPO registration was made on the basis of the levels of diene conjugates and Schiff's bases. The activity of enzymes of transmembranous transportation-calcium, magnesium, sodium/potassium pump--was studied. The levels of the LPO markers were found to be tending to an increase in the active stage of the disease and to a decrease in its remission. Though the initial control levels of the markers were not reached. In the active stage of the disease the levels of diene conjugates were 59.66 +/- 6.43 nmol (42.6 +/- 94 nmol/litre in the control) while in the remission they were 22.16 +/- 3.22 a. u. (14.80 +/- 1.06 in the control). The results obtained are indicative of the polymorphism of clinically manifest metabolic changes. In the patients with higher levels of Ca2-ATPase the disease ran more silent than in those in whom the enzymic functional activity were lower. Inadequate activity of enzyme transmembranous transportation revealed in some patients in the course of manifest inflammation was a direct reflection of the failure in the mechanism of adaptation and an evidence of the initially heterogeneous activity (individuality) the enzymes of transmembranous cation transportation. The revealed phenomena contributed to the clinical course of pyelonephritis in a particular person and with regard to pathogenetic mechanisms required an approach to the therapy on an individual basis.

Two new laboratory diagnostic tests for chronic glomerulonephritis and pyelonephritis have been developed. The first one is based on electrophoretic mobility of urinary lysozyme under certain conditions, such as the use of 12% polyacrylamide gel with pH of 4.3 and acid electrode buffer with pH of 4.0. After electrophoresis was discontinued, lysozyme position was determined by lysis of Micrococcus lysodeikticus, used as test agents and added to the gel as a suspension prior to polymerization. Urinary lysozyme was found to be in the anode area of the gel in 95% of patients with chronic pyelonephritis, and in its cathode area in 92% of patients with chronic glomerulonephritis. There was no lysozyme in the urine of normal subjects. The other laboratory technique, the ethanol test, is based on comparative assessment of the degree of urinary opacification after ethanol is added in conditions of neutral reaction (following the addition of physiologic saline) and marked alkaline reaction (following the addition of sodium hydroxide solution). The ratio of optic density of the alkaline specimen to that of the neutral specimen was above 1 in patients with chronic glomerulonephritis, and below 1 in patients with chronic pyelonephritis and normal subjects. Examination of biochemical mechanisms of the proposed tests has demonstrated that the pattern of proteinuria is the most important factor affecting the results.

Patients with pyelonephritic renal scarring are at risk of developing renal failure and hypertension. We studied glomerular filtration rate (GFR), renal plasma flow (RPF), filtration fraction (FF), systolic (SBP) and diastolic (DBP) blood pressure, fractional sodium, potassium and phosphate excretion, peripheral renin activity (PRA), plasma aldosterone (p-Aldo), urinary albumin excretion (U-Alb) and urinary beta 2-microglobulin excretion (beta 2-M) in hydropenia and during transition to 3% volume expansion with isotonic saline infusion in 22 female patients with renal scarring due to pyelonephritis and 9 healthy controls. The patients had significantly lower GFR, higher SBP and higher PRA in hydropenia, but there was no significant difference in RPF, FF, DBP or p-Aldo. After volume expansion, SBP, DBP, PRA and p-Aldo were significantly higher in patients than in controls. Transition to 3% volume expansion was associated with a similar increase in SBP in both patients and controls, whereas DBP increased significantly more in the patients (p less than 0.01). Volume expansion resulted in a significant suppression of PRA and p-Aldo in both patients and controls. The patients with renal scarring had the same capacity to excrete sodium and water during transition to volume expansion as the healthy controls. The renin-aldosterone system seems abnormally activated and is probably more important than hypervolemia in the development of hypertension in this group of patients.
