ABSTRACT

We evaluated the correlation between the conventional manual serological testing method for syphilis and a novel automated serological testing method and between six different reagents used in the automated method. Twenty-six serum samples, which were positive on non-treponemal manual serological testing, were obtained from 19 patients with early syphilis. The samples were manually analyzed using the non-treponemal serological test for syphilis kit and automatically analyzed using six different reagents approved by the Ministry of Health, Labor and Welfare in Japan. Statistically significant correlations were observed between most of the reagents used in the automated testing (r = 0.652-0.996, P < 0.001), except for one combination of the reagents. In the simple regression analysis, the slope of the simple regression line (range, 0.014-3.040) and some of the regression coefficients were not equal to 1.0. Therefore, it is recommended that when the automated serological testing method is used to test for syphilis, the same reagent should be consistently selected to evaluate the changes in antibody titers. Statistically significant correlations were also observed between the manual method and all the reagents used in the automated method (r = 0.682-0.811, P < 0.001). In this case, the regression coefficients ranged 0.375-6.270, and the simple regression line intercept ranged -71.926 to 4.184. The regression coefficient and the intercept between the manual method and some of the reagents used in the automated method were not similar to the values described in the documentation attached to the reagents used in this study.

ABSTRACT

We investigated the efficacy and safety of levofloxacin (LVFX) 500mg once a day in patients with non-gonorrheal urethritis. Men, aged 20 years or older, with urethritis symptoms, and detection of Chlamydia trachomatis (C. trachomatis) or Mycoplasma genitalium (M. genitalium) by a microbiological examination were eligible for this study. Patients were administered LVFX 500mg, orally, once a day and the dosage period was seven days. We assumed 22 patients for a safety and efficacy analysis. In 22 patients, 17 patients had urethritis with C. trachomatis, 4 patients urethritis with M. genitalium, and one patient mixed infection of C. trachomatis and M. genitalium. In the clinial study, the primary endpoint was set as the bacteriological eradication rate at two to four weeks after completion of treatment. The bacterial eradication rate in the urethritis was 86.4% (19/22). The bacterial eradication rate in the urethritis with C. trachomatis, M. genitalium, and mixed infection of C. trachomatis and M. genitalium were 94.1% (16/17), 50.0% (2/4), 100% (1/1), respectively. A significant difference was not recognized among the three groups. The clinical efficacy at two to four weeks after completion of treatment was 90.9% (20/22). The clinical efficacy rates in the urethritis with C. trachomatis, M. genitalium, and mixed infection of C. trachomatis and M. genitalium were 100% (17/17), 50.0% (2/4), 100% (1/1), respectively. The efficacy rate of urethritis with M. genitalium was significantly low. No adverse drug reactions were observed. These results suggest that once-a-day levofloxacin (500mg) is effective and safe treatment for non-gonorrheal urethritis.

ABSTRACT

Neisseria gonorrhoeae were isolated from pharyngeal specimens of male and female patients and also from urethral and cervical discharges of male and female patients, respectively, suspected of having gonococcal infections in a urologic clinic in Kawasaki City. Microbiological and epidemiological studies were performed in 127 male and 41 female patients. The specimens were streaked onto the modified Thayer-Martin Selective Agar and the plates were incubated at 35 degrees C for 48 h under an atmosphere of 10% CO2. In 127 male patients, N. gonorrhoeae were detected in 117 (92.1%) of the urethral specimens. In these patients, N. gonorrhoeae were detected in pharyngeal specimens from 14 (11.0%) patients, but the pathogen was also detected in urethral specimens from these patients without exception. In 41 female patients. N. gonorrhoeae were detected in 20 (48.8%) of the 41 cervical discharges. When the pharyngeal specimens were tested, N. gonorrhoeae were detected in 14 (34.1%) of the 41 specimens. N. gonorrhoeae was simultaneously detected only in pharyngeal and cervical specimens from 11 of the 41 female patients and the pathogen was detected only in pharyngeal specimens from other 3 patients. There were no marked differences in antimicrobial susceptibilities between N. gonorrhoeae isolates from pharyngeal specimens and those from urethral or cervical discharges in all the patients tested. The PFGE patterns of 50 gonococcal isolates (25 pairs) from 25 patients (14 males and 11 females) in whom N. gonorrhoeae were simultaneously detected from pharyngeal and urethral or cervical specimens were analyzed. In 24 of 25 patients. N. gonorrhoeae isolated from the pharyngeal and urethral or cervical specimens in the same patients showed the same PFGE patterns. However, the 25 pairs showed the different PFGE patterns. From these results it is clarified that N. gonorrhoeae are detected in the pharyngeal specimens from considerable numbers of patients with gonorrhea, and there is a possibility that the pathogens prevailing among the patients differ in genetic sources.
