OBJECTIVES: We evaluated the use of treponemal serum tests in cerebrospinal fluid (CSF) to diagnose neurosyphilis since CSF-Venereal Disease Research Laboratory (VDRL) is specific but lacks sensitivity. METHODS: We tested CSF specimens using the following treponemal serum tests: INNO-LIA, Treponema pallidum particle agglutination (TP-PA), Trep-Sure, and Maxi-Syph. The reference standard to calculate sensitivity and specificity was having two or more reactive/positive tests on CSF...

BACKGROUND: Discordant results have been reported between treponemal-specific enzyme immunoassays (EIA) screening and confirmatory tests such as the Treponemal pallidum particle agglutination (TPPA) assay. The performance of IgG EIA screening in specific populations, such as pregnant women, is not well defined. We reviewed laboratory results of 34,251 samples from individuals who underwent IgG EIA screening at a large Boston academic medical center, so as to calculate positive concordance of these screening tests with a confirmatory TPPA or subsequent rapid plasma reagin (RPR) test by age, gender, pregnancy, and obstetric or gynecologic (Ob/Gyn) service...

Syphilis is a frequent coinfection with human immunodeficiency virus (HIV). Whereas systemic syphilis infection increases plasma HIV RNA levels (viral load; VL), effects of syphilis on cerebrospinal fluid (CSF) VL are unknown. We hypothesized that intrathecal immune activation in neurosyphilis would selectively increase CSF VL in coinfected patients. In this study, HIV-infected research subjects (N = 225) were categorized into three groups based on serum rapid plasma reagin (RPR), microhemaglutination for Treponema pallidum (MHA-TP) MHA-TP, and CSF VDRL: 23 with neurosyphilis (NS+; reactive serum RPR and MHA-TP and positive CSF VDRL); 42 with systemic syphilis but not neurosyphilis (Syph+; reactive serum RPR and MHA-TP; negative CSF VDRL), and 160 without syphilis (Syph-; nonreactive serum RPR)...

Using the Captia Select Syph-G enzyme-linked immunosorbent assay (ELISA), we analyzed the sera of 1,771 patients from a high-risk population attending sexually transmitted disease (STD) clinics. We focused on discrepancies between the results of the immunoglobulin G (IgG) ELISA and the Treponema pallidum hemagglutination (TPHA) test. We identified 57 patients (3.22%) with conflicting results in the IgG ELISA and TPHA test. In order to resolve these discrepancies, these patients' health records were reviewed and additional serological tests (rapid plasma reagin, IgM ELISA, fluorescent treponemal antibody absorption, and Western blotting) were performed...

Enzyme immunoassay (EIA) using recombinant antigens for the detection of Treponema pallidum-specific antibodies in sera of syphilis patients was developed. Four low-molar-mass Treponema antigens (Tp15, Tp17, TmpA, Tp47) were investigated; 17- and 47-kDa proteins were demonstrated as immunodominant as they permitted to obtain the most sensitive EIA. Using a mixture of these proteins a 3rd-generation-EIA kit Dia-Syph was constructed, its sensitivity being 99.4% during tests of 165 sera of syphilitic patients...

Syphacia sp. is a common intestinal parasite in conventionally-housed laboratory rodents. Although gross lesions are rare in oxyuriasis, it is possible that more subtle changes may develop, which may affect research results. In this study, we analysed the responsiveness to beta-adrenergic stimulation by isoproterenol (ISO) of left atria isolated from Syphacia-infested (SYPH) and control, non-infested adult male Wistar rats (CONT). In the non-infested animals, ISO pD(2) was not significantly changed by ivermectin treatment...

While there is little literature on the way in which people protected themselves against the sun, evidence from paintings suggest that clothing covering the body, veils and large brim hats were used by ancient Greeks, and that umbrellas existed in ancient Egypt, Mesopotamia, China and India. Veiel in 1887 (Vierteljahresschr. Derm. Syph. 14, 113-116) was able to protect a patient with eczema solare by the use of a tightly woven red veil. In 1889, Widmark (Uber den Einfluss des Lichtes auf die Haut. Hygiea, Festband #3, Samson and Wallin, Stockholm) used acidified quinine sulfate to absorb UVB, apparently because, since quinine fluoresces when irradiated with UVR, he rightly assumed that it would absorb the short wavelengths...

Anticardiolipin antibodies (aCL) are induced both in the Antiphospholipid Syndrome (APS) and syphilis, but thrombosis, thrombocytopenia, and pregnancy loss occur only in the APS. Differences in specificity and function of aCL antibodies might explain clinical differences between APS and syphilis. This study compared the effects on platelet activation and aggregation of affinity purified IgG anticardiolipin antibodies from 6 patients with the APS (IgG-APS) and 5 patients with syphilis (IgG-syph). Platelet aggregation was studied by aggregometry and platelet activation by flow cytometry...

To determine whether characteristics that are correlated with male homosexual behavior are associated with the incidence of cancer, the names of persons with a diagnosis of cancer in western Washington during 1974 to 1979 were linked to those in the state syphlis registry. Eight of 47 men with anal cancer were found to have had a reactive FTA test result; the expected number, based on the proportion of reactive cases among men with other sites of cancer, was only 0.40. Among men with anal cancer identified through ten population-based cancer-reporting systems in the United States, 24...

AIM: The Captia Syph G enzyme immuno assay (EAI) offers the potential for the rapid automated detection of syphilis antibodies. This study was designed to assess the role of other sexually transmitted diseases (STDs) in producing false positive reactions in the Captia Syph G EIA. The role of rheumatoid factor (RF) as a potential source of false positives was also analysed. METHODS: Patients who attended a genitourinary medicine (GUM) department and gave a false positive reaction with the EIA between 1988 and 1990 were compared with women undergoing antenatal testing and with the control clinic population (EIA negative) over the same time period...

AIMS: To review the performance of the Venereal Diseases Research Laboratory (VDRL) test and the Treponema pallidum haemagglutination assay (TPHA) as a combined screen for syphilis to provide a baseline for assessing screening by anti-treponemal IGG EIA. METHODS: Between 1980 and 1987 all serum samples were screened by both VDRL and TPHA tests. The FTA-ABS test was also used in suspected early primary syphilis, or when one of the other tests was positive. A positive result in a screening test was confirmed by quantitative testing...
