Since the 1970s in Korea, consistent with the global tendency there really has been a rapid decrease in favorable rates for syphilis. In 2000, 0.2% of the general Korean population was estimated to be syphilis-positive; since that time, amounts appear to have decreased, and the prevalence rate is still quite low. 1 Despite these low rates, syphilis is an important disease since it can cause serious health issues including neurosyphilis and congenital infection. Appropriate screening, evidence and follow-up protocols are required. Std Test closest to Crooked Creek, AK, United States. 2-4 Serological evaluation 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 evaluation, have been used to diagnose and monitor syphilis infections. Lately, there have been issues regarding selection of the most effective algorithm for initial screening and follow up by either non-treponemal- or treponemal-specific evaluations. 2 5 6 The Centers for Disease Control and Prevention (CDC) still advocate that a non-treponemal reagin test is utilized as the first-line diagnostic approach. 2 Two kinds of non-treponemal test have been extensively used: VDRL and RPR. RPR is the most common first-line non-treponemal test used to screen for syphilis disease. Crooked Creek, Alaska Std Test. 7 Recently, automated RPR tests are introduced, when the automated evaluation was compared with conventional RPR card evaluations but variable results were reported. 8 The automated RPR test has some advantages over the traditional RPR card test, for example greater capacity 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 to April 2013 from a university hospital were included, together with matched controls. Remnant sera from requested treponemal tests after verification were included and maintained at 70C until investigation. Patients were not categorised according to syphilis phase because of the infrequency of syphilis disease. Cases of syphilis that is accurate were quite rare because of the low prevalence of syphilis in this country. The purpose of the study was to appraise the same RPR evaluations with safe remnant specimens that are ethically. 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 automobile 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 CA-400 photometric analyser was used for analysis and the automated procedure. 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 signify 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 then twofold serial dilutions were made with 25 L sample diluent. The particles that are sensitised were serially combined in the neighbouring wells with a plate mixer for 30 s. After 2 h of incubation at room temperature, the end result of the agglutination assay was read. The Serodia TPPA assay results were interpreted utilizing the agglutination patterns of positive and negative controls.

The percentage deal ( coefcient) of the automated RPR test with the manual RPR card test was computed. The overall sensitivity and specificity of each test were computed based on the TPPA results. values were used to categorise results as quite great (0.81-1.0), great (0.61-0.8), average (0.41-0.6), reasonable (0.21-0.4) or inferior (0-0.2). Std test nearby Crooked Creek AK. 9 The McNemar test was used to compare seroconversion rates between the automated RPR test and the traditional 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 evaluations, 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 favorable on the HBI HiSens Auto RPR LTIA test but negative on the BD Macro-Vue RPR card test. These two cases were negative on the TPPA evaluation. Crooked Creek Std Test. There were four results with discrepancies between both the RPR evaluations and the TPPA assay, which was due to conditions other than syphilis disease ( table 2 ). The strength of agreement between the automated RPR and manual RPR tests was 'reasonable' ( value 0.296, 59 TPPA-favorable results; value 0.293, 53 TPPA-negative effects) according to the TPPA results ( table 3 ).

Std test near Crooked Creek, Alaska. The overall sensitivity and specificity of the HBI HiSens Auto RPR LTIA evaluation 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 normal RPR card test (4.3% (1/23)) (p=0.004) by the McNemar test. A thorough comparison of the treated syphilis cases is given in table 5

The manual RPR test has been put to use for decades, but lately an automated RPR test was established and has been used because of its convenience in clinical settings. However, there was a comparison of results of the new automated test together with the traditional manual RPR test in diagnostic approaches plus a need for thorough inspection. Treponemal test results will not change even after treatment, as well as the patients reside irrespective of treatment or disease activity with positive results for the rest of their lives. Treponemal tests cannot discriminate between past infections, active disease -treated patients. 10 In contrast, non-treponemal tests can discriminate between patients that have been treated during the primary or secondary stage of the illness. When the primary or secondary stage of a first T. pallidum infection is treated, the non-treponemal test titre should demonstrate a twofold dilution fall after treatment, usually within 6 months. Std test closest to AK. 7 Thus, the non-treponemal test is essential for handling syphilitic patients.

In our study, the conventional BD Macro-Vue RPR card test revealed better sensitivity in relation to the HBI HiSens Auto RPR LTIA test in syphilis screening, even though the automated RPR test does have some edges in the clinical setting. As an example, the automated RPR test reduced the workload and total test turnaround time. It does not need test experts and can also deal with greater evaluation quantities in a given time in relation to the RPR card test that is manual. Additionally, we discovered that the automated RPR test could be utilized as a monitoring marker of treatment response, particularly if treponemal tests are used for first-line screening of syphilis as a reverse algorithm of syphilis testing. This reverse algorithm for syphilis testing has been suggested and adopted in many fields since it could 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 urge first screening for syphilis with a non-treponemal test like RPR. 2

The Chancre Of Syphilis

Our study found the automated RPR test revealed earlier seroconversion than the conventional card RPR test after syphilis treatment (p=0.004). If we adopt the reverse algorithm, treponemal tests could be used to screen and then non-treponemal tests can be utilized to correctly show negative changes in treated cases. In this case, we could use treponemal tests for first-line screening and non-treponemal tests for observation patients allowing us to detect seroconversion more efficiently after treatment. 2 13 14 Regrettably, our study had a limited variety of syphilitic patients because of the low prevalence of syphilis in our country, so the variety of samples was little and couldn't been classified according to syphilis stage. In fact, in certain late or latent syphilis cases, the outcome of the non-treponemal test were difficult to interpret after first treatment in our study (cases 8 and 9 in table 5 ). So, further well-designed studies are needed to clarify the serological results of automated RPR tests after treatment and according to the point of syphilis disease.

In clinical laboratories, automated RPR tests have lately been introduced in Korea, and evaluations comparing standard RPR tests and VDRL tests have been reported. 8 15 Nevertheless, the results were varying. Onoe et al 16 additionally proposed that, when the automated serological testing approach is used in clinical settings, exactly the same reagent should be consistently selected to assess the changes in antibody titres, because the manual serological testing way of syphilis showed somewhat different consequences from the automated serological testing processes. In this study, we noticed relatively consistent results between manual and automated RPR evaluations.

In conclusion, the automated RPR test revealed an overall lower sensitivity and similar specificity compared with the conventional manual RPR card test. Therefore, we consider that the automated RPR test is not appropriate for use for initial screening for syphilis. Nevertheless, it generates an seroconversion reaction in treated cases compared to the conventional RPR card test. Applying the inverse algorithm, the sensitive treponemal test can be utilized as the first-line screening evaluation, and then the automated RPR test can be used as an adjunct to discover earlier seroconversion in treated patients.

Results The percentage agreement 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 standard RPR card test revealed overall higher positivity compared to the automated RPR test, whereas the automated RPR test demonstrated higher seroconversion (43.5%, 10/23) than the conventional RPR card test (4.3%, 1/23) in treated patients.
