Since the 1970s in Korea, consistent with the global trend, there's been a rapid decline in positive rates for syphilis. In 2000, 0.2% of the general Korean population was estimated to be syphilis-positive; since that time, amounts seem to have decreased, and the prevalence rate is still very low. 1 Despite these low rates, syphilis is an important infection because it can cause serious health problems including neurosyphilis and congenital disease. Appropriate evidence, screening and follow-up protocols are demanded. Std test in Coral MI, United States. 2-4 Serological analysis of non-treponemal reagin tests, including the Venereal Disease Research Laboratory (VDRL), rapid plasma reagin (RPR) and treponemal tests including the Treponema pallidum haemagglutination assay (TPHA), the Treponema pallidum particle agglutination (TPPA) evaluation, the fluorescent treponemal antibody absorption test, and also the Treponema-specific antibody test, have been employed to diagnose and track syphilis diseases. Recently, there have been problems regarding selection of the most effective algorithm for initial screening and follow up by either non-treponemal- or treponemal-specific tests. 2 5 6 The Centers for Disease Control and Prevention (CDC) still urge that a non-treponemal reagin test is utilized as the first-line diagnostic strategy. 2 Two types of non-treponemal test have been broadly used: VDRL and RPR. RPR is the most common first-line non-treponemal test used to screen for syphilis infection. Coral Michigan Std Test. 7 Lately, automated RPR tests are introduced, but variable results were reported when the automated evaluation was compared with standard RPR card tests. 8 The automated RPR test has some advantages over the traditional RPR card test, including greater ability to manage a great number of samples, minimal person to person variation, and straightforward automated procedures.

All sera testing positive for syphilis by one or more tests from November 2012 from a university hospital to April 2013 were included, together with matched controls. Remnant sera from requested treponemal tests after evidence were contained and maintained at 70C until analysis. Patients were not categorised according to syphilis phase due to the infrequency of syphilis disease. Cases of syphilis that is authentic were quite rare due to the low prevalence of syphilis in this state. The purpose of this study was to evaluate the same RPR tests with ethically protected remnant specimens. The institutional review board exempted this case. All study processes complied with the World Medical Association Declaration of Helsinki.

HiSens Auto RPR LTIA (HBI, Anyang, Korea) is a latex turbidimetric immunoassay using latex particles coated with lecithin and cardiolipin. The latex particles react with the reagin in the serum of patients with syphilis. The 15 L serum samples were allowed to react with 120 L Hisens vehicle RPR LTIA R1 (buffer) and 60 L Hisens auto RPR LTIA R2 (latex reagent comprising cardiolipin-lecithin-cholesterol, 1.0 mg/mL) in CA 400 autoanalyzer (Furuno Electric Co, Nishinomiya, Japan). The CA400 photometric analyser was utilized for the automated process and analysis. Absorbance at 600 nm was read after 5.3 and 10 s at room temperature, in duplicate. Results of the HiSens vehicle RPR test equal to or greater than 1.0 RPR unit (RU) were considered to indicate reactive RPR. The upper detection limit was 20 RU.

The Serodia TPPA assay (Fujirebio, Tokyo, Japan) is based on agglutination of coloured gelatine particles that have been sensitised (coated) with T. pallidum (Nichols strain) antigen. For every specimen, a 100 L sample of diluent and 25 L test specimen were blended, and twofold serial dilutions were made with 25 L sample diluent. The particles that are sensitised were combined in the neighbouring wells with a plate mixer for 30 s. After 2 h of incubation at room temperature, the consequence of the agglutination assay was read. The Serodia TPPA assay results were interpreted using the agglutination patterns of negative and positive controls.

The percentage deal ( coefcient) of the automated RPR test with the manual RPR card test was calculated. The overall sensitivity and specificity of each and every test were calculated predicated on the TPPA results. values were used to categorise results as really good (0.81-1.0), great (0.61-0.8), average (0.41-0.6), fair (0.21-0.4) or inferior (0-0.2). Std test near me Coral MI. 9 The McNemar test was utilized to compare seroconversion rates between the automated RPR test and the conventional manual RPR card test and was performed using SPSS Statistics V.20. A p value

There were 24 discrepant results (21.4%) between the two RPR tests, including 22 negative HBI HiSens Auto RPR LTIA test results that demonstrated positive results on the BD Macro-Vue RPR card test. Of these 22 discrepant results, 20 were TPPA positive and 2 were TPPA-negative, while 2 cases were positive on the HBI HiSens Auto RPR LTIA evaluation but negative on the BD Macro-Vue RPR card test. These two instances were negative on the TPPA evaluation. Coral Std Test. There were four results with disparities between both the RPR tests and the TPPA assay, which was due to states aside from syphilis disease ( table 2 ). The power of agreement between the automated RPR and manual RPR evaluations was 'honest' ( worth 0.296, 59 TPPA-favorable results; value 0.293, 53 TPPA-negative effects) according to the TPPA results ( table 3 ).

Std test in Coral Michigan. The overall sensitivity and specificity of the HBI HiSens Auto RPR LTIA test based on TPPA results were 52.5% (95% CI 39.1% to 65.7%) and 94.3% (95% CI 84.3% to 98.8%), respectively. The overall sensitivity and specificity of the BD Macro-Vue RPR card test were 86.4% (95% CI 75% to 93.9%) and 94.3% (95% CI 84.3% to 98.8%), respectively ( table 4 ). Automated RPR provided a higher seroconversion rate after syphilis treatment (43.5% (10/23)) than the standard RPR card test (4.3% (1/23)) (p=0.004) by the McNemar test. A detailed comparison of the treated syphilis cases is given in table 5

An automated RPR test was launched and has been used because of its convenience in clinical settings, but although the manual RPR test has been used for decades. Nonetheless, there was a comparison of outcomes of the new automated evaluation with the conventional manual RPR test in diagnostic approaches and a requirement for thorough inspection. Treponemal test results will not change after treatment, and also the patients dwell with positive results for the remainder of their lives regardless of treatment or disease activity. Treponemal tests cannot discriminate between past infections, active disease, treated patients and non -treated patients. 10 In comparison, non-treponemal tests can discriminate between patients that have been treated during the primary or secondary phase of the disease. When the primary or secondary phase of a first T. pallidum infection is treated, the non-treponemal test titre should show a twofold dilution fall after treatment, usually within 6 months. Std Test nearby MI. 7 So, the non-treponemal test is important for managing syphilitic patients.

In our study, the standard BD Macro-Vue RPR card test showed better sensitivity than the HBI HiSens Auto RPR LTIA evaluation in syphilis screening, although the automated RPR test does have some advantages in the clinical setting. For example, the automated RPR test reduced the workload and total evaluation turnaround time. It doesn't need evaluation experts and can also deal with greater evaluation amounts in a given time than the RPR card test that is manual. Moreover, we discovered the automated RPR test could be utilized as a monitoring mark of treatment response, particularly when treponemal tests are used for first-line screening of syphilis as a reverse algorithm of syphilis testing. This inverse algorithm for syphilis testing was proposed and adopted in several fields because it might be more sensitive and powerful in relation to the traditional algorithm 3 4 6 in a low-prevalence area and can be automated. On the other hand, the CDC still advocate first screening for syphilis with a non-treponemal test like RPR. 2

Our study found that the automated RPR test demonstrated earlier seroconversion than the traditional card RPR test after syphilis treatment (p=0.004). If we embrace the reverse algorithm, treponemal tests could be used to screen sensitively, and then non-treponemal tests could be used to precisely reveal negative changes in treated cases. In this case, we could use treponemal tests for first-line screening and non-treponemal tests for tracking patients allowing us to detect seroconversion more effectively after treatment. 2 13 14 Unfortunately, our study had a limited variety of syphilitic patients due to the low prevalence of syphilis in our nation, so the number of samples was little and could not been classified according to syphilis phase. Actually, in certain late or latent syphilis cases, the outcome of the non-treponemal test were difficult to interpret after initial treatment in our study (cases 8 and 9 in table 5 ). So, further well-designed studies are needed as stated by the phase of syphilis infection and to clarify the serological results of automated RPR evaluations after treatment.

In Korea, automated RPR tests have lately been introduced in clinical laboratories, and assessments comparing conventional RPR tests and VDRL tests are reported. 8 15 Nevertheless, the results were variable. Onoe et al 16 additionally proposed that, when the automated serological testing system is utilized in clinical settings, exactly the same reagent should be consistently selected to evaluate the changes in antibody titres, as the manual serological testing way of syphilis revealed somewhat different results from the automated serological testing approaches. In this study, we noticed fairly consistent results between automated and manual RPR evaluations.

In conclusion, an entire lower sensitivity and similar specificity was shown by the automated RPR test compared with the conventional manual RPR card test. Therefore, we consider the automated RPR test is not appropriate for use for first screening for syphilis. Nevertheless, it produces an seroconversion response in treated cases than the normal RPR card test. Using the reverse algorithm, the sensitive treponemal test may be utilized as the first-line screening test, and the automated RPR test can be utilized as an adjunct to detect earlier seroconversion in treated patients.

Results The percentage arrangement between the two RPR tests was 78.6% ( 0.565; 95% CI 0.422 to 0.709). Sensitivity and specificity of the automated RPR test relative to the TPPA test was 52.5% (95% CI 39.1% to 65.7%) and 94.3% (95% CI 84.3% to 98.8%), respectively, while the same values for the conventional RPR card test were 86.4% (95% CI 75% to 93.9%) and 94.3% (95% CI 84.3% to 98.8%), respectively. The normal RPR card test demonstrated overall higher positivity in relation to the automated RPR test, while the automated RPR test revealed higher seroconversion (43.5%, 10/23) than the conventional RPR card test (4.3%, 1/23) in treated patients.
