    Description / Table of Contents: Zusammenfassung Wir untersuchten den Nutzen des Eintauchteststreifens zur Ermittlung einer Leukozyturie und Bakteriurie für die Diagnosestellung einer Harnwegsinfektion (HWI). Der Esterase-Streifentest läßt sich schnell durchführen; damit kann die Leukozytenesterase sehr leicht im Urin festgestellt werden. Der Nitrit- Streifentest zur Ermittlung einer Bakteriurie korrelierte dagegen sehr schlecht mit den Ergebnissen der Urinkultur. Daraus ergibt sich, daß der Esterase-Teststreifen zur Ermittlung einer Leukozyturie im Gegensatz zum Nitrit-Streifentest bei der Diagnosestellung einer HWI nützlich ist. Katheter-bedingte HWI sind die am schwierigsten zu behandelnden Gruppen von HWI. Einer der Gründe dafür ist die Bildung von Biofilm auf der Katheteroberfläche. Wir untersuchten die Wirksamkeit des Katheterwechsels unmittelbar vor Therapiebeginn einer Katheter-bedingten HWI, wobei zur Therapie 300 oder 600 mg/Tag Levofloxacin, eines der neueren Chinolone, verwendet wurde. Wir konnten jedoch keinen Einfluß dieser Maßnahme auf die Medikamentenwirksamkeit nachweisen.
    Notes: Summary We examined the value of the dipstick test for detecting pyuria and bacteriuria in the diagnosis of urinary tract infection (UTI). The dipstick esterase test could be quickly assessed and could easily detect leukocyte esterase in the urine. This was well correlated with the conventional sedimentation method. The dipstick nitrate reduction method for detecting bacteriuria, however, was not well correlated with the urine culture method. These findings suggested that the dipstick esterase test was a useful method for detecting pyuria in the diagnosis of UTI, but not the dipstick nitrate reduction method. Catheter-associated UTI is the most difficult category of UTI to treat and control. One of the reasons for this is the formation of biofilm around the indwelling catheter. We attempted to evaluate the effect of catheter exchange just before treatment of catheter-associated UTI with either 300 or 600 mg/day of levofloxacin, one of the newer quinolones. However, we are unable to find any apparent effect on the drug's efficacy.

    Notes: Abstract  A total of 20 patients with hormone-refractory prostate carcinoma entered a pilot study of combination chemotherapy based on the EAP (etoposide, Adriamycin and cisplatin) regimen, in which Adriamycin was replaced by pirarubicin, a less cardiotoxic derivative of Adriamycin. The response was assessed by criteria modified from those of the National Prostatic Cancer Project: prostate-specific antigen was employed instead of acid phosphatase. Of 18 evaluable patients, 6 achieved a partial response, 5 had stable disease, and in 7 the disease had progressed during therapy; thus, the overall response rate was 33.3% [95% confidence interval (CI) 11.5–55.1%]. Significant pain alleviation and performance status improvement were obtained in 5 of 12 patients (41.7%; CI 13.8–69.6%) and 3 of 13 patients (23.1%; CI 0.2–46.0%), respectively. Although myelosuppression was moderate to severe, no chemotherapy-related deaths or bacteriologically documented sepsis occurred; nor was there any clinical cardiotoxicity. All the responding patients received maintenance chemotherapy with etoposide thereafter. At present, the median duration of response is 33 weeks (range: 23–91 weeks) and the median survival period for all patients is 42 weeks (range: 27+ –136 weeks), with 12 deaths. In spite of the small number of patients treated, these results suggest that this chemotherapy regimen is active in advanced hormone-refractory prostate carcinoma.

    Notes: Summary Renal scars are thought to be the end stage of chronic pyelonephritis and one of the most important causes of renal insufficiency and renal hypertension. The role of bacterial pili was examined in scar formation after an infection of newly constructed bacterial strains using the recombinant DNA technique, which possessed either mannose resistant (MR) or mannose sensitive (MS) pili of Serratia marcescens. Strains that differed in only a single virulence factor, namely, MR or MS pili, were used in a rat model of chronic pyelonephritis. In this model, MS-piliated bacteria stimulated renal scarring more severely than non-piliated or MR-piliated bacteria.

    Notes: Summary Hyperosmolority in the urinary tract inhibits the host defense against bacterial infection. NaCl contributes most to osmolority in the renal medulla and urine. Therefore, we studied the effect of hyperosmolar NaCl on neutrophil function. When osmolarity was increased by NaCl, polymorphonuclear leukocytes (PMNL) became defective in phagocytosis, intracellular killing of bacteria, chemotactic activity, and superoxide production. This coincided with a decrease in the intracellular adenosine triphosphate (ATP) content of PMNL. Both the inhibition of superoxide production and the reduction in ATP content did not occur at 4°C. By increasing ATP content, phosphoenol pyruvic acid (PEP) protected against the decrease in superoxide production. These results suggest that leukocyte function is inhibited by high concentrations of NaCl due to the activation of the Na+−K+ pump. PEP, an ATP precursor, can protect PMNL against osmotic stress by raising the intracellular concentration of ATP.

    Notes: Summary We tested the first portion of voided urine (FVU) and urethral swab from 80 patients with nongonococcal urethritis (NGU) using a novel enzymeamplified immunoassay (IDEIA) for the detection of Chlamydia trachomatis antigen. Urine specimens were positive in all patients with positive urethral swabs (positive coincidence ratio, 100%) and in 6 of 54 patients with negative swabs (negative coincidence ratio, 88.9%). Our data suggest that FVU is suitable for the detection of Chlamydia trachomatis antigen using the IDEIA test in patients with NGU.

    Notes: Summary The role of superoxide in scar formation following renal infection caused by mannose-sensitive (MS) piliated strains of bacteria was studied in the experimental pyelonephritis model using female Sprague-Dawley rats. The MS piliated strain stimulated renal scarring to a significantly greater extent than either the non-piliated or MR-piliated strain. Modulation of leukocytes by administering cyclophosphamide to induce neutropenia and colchicine to inhibit leukocyte migration was effective in preventing renal scarring. Treatment with superoxide dismutase during the early stage of infection was also effective in preventing scar formation. Finally, the production of superoxide by rat leukocytes was significantly larger following stimulation by MS piliated than either the nonpiliated or MR piliated strains. These observations suggest that superoxide released from leukocytes plays a critical role in the development of renal scarring following a bacterial infection, especially by MS piliated strains.

    Notes: Summary Endotoxin is a component of the outer membrane of gram-negative rods (GNR). Since GNR are responsible for the majority of urinary tract infection (UTI), we measured the concentration of endotoxin in urine using chromogenic endotoxin-specific assay and examined its diagnostic utility in patients with suspected UTI. In all 18 urine samples with an endotoxin concentration exceeding 350 pg/ml and 2 samples with 10–350 pg/ml of endotoxin concentration, GNR were detected at a count of 104 cfu/ml. Negative for endotoxin were 3 samples of culture positive for grampositive cocci (GPC), 2 samples containing various bacterial contaminants and all 37 samples with no growth on culture. Two urine samples collected 5 h after antibiotic dosage showed negative culture for GNR but a significant concentration of endotoxin. In an in vitro experiment, a residual concentration of antibiotic in urine inhibited bacterial growth, leading to a falsenegative culture. These results suggest that chromogenic endotoxin assay is a reliable method for diagnosing UTI caused by GNR and detecting false-negative culture of GNR.
