| How to handle Western blot (WB) seroindeterminate individuals for Human T-lymphotropic Virus 1/2 (HTLV-1/2) constitutes a challenge for blood banks and fam ilies. We made a cross-sectional study of 191 enzyme linked immunoassay (EIA) reactive individuals from the hematological center (HEMOCE) of Fortaleza (Brazil), examining their serological (WB) and molecular (PCR) diagnosis, and demographic profiles, as well as a possible association of their condition with other infectious pathologies and risk factors. Ethical institutional approval and personal consent were obtained. Out of 191 EIA reactive individuals, 118 were WB seroindeterminate and 73 were seropositive for HTLV-1/2. In the PCR analysis of 41 WB seroindeterminate individuals, 9 (22%) were positive... |

| Abstract Background The Roma ethnic group is the largest and most marginalized minority in Europe, believed to be vulnerable to sexually transmitted infections. Aim The purpose of the study was to investigate frequency and characteristics of gonorrhea and syphilis among the Roma population in Belgrade. Methods Data from the City Institute for Skin and Venereal Diseases to which all gonorrhea and syphilis cases are referred were analyzed. Results During the period of 2010–2014 sexually transmitted infections were more frequent among Roma than in rest of Belgrade population. Average percentages of Roma among all reported subjects with syphilis and those with gonorrhea were 9.6% and 13.5%, respectively, while the percentage of Roma in the total Belgrade... |

| Abstract The aim of this study was to evaluate self-reported syphilis and associated factors in sexually active young adults (16-25 years old) in the Public Health System in Brazil. This was a cross-sectional study with 8071 participants recruited from 119 primary care units. Of these, 224 (2.86%, 95% CI 2.29-3.43%) reported having the disease. Age, lower socio-economic class, being a smoker, not using a condom at first sexual intercourse, and ever had a same-sex sexual experience were associated with syphilis. The results reinforce the importance of implementing strategies focused on socio-economic class and early sexual education that encourage condom use from the beginning of sexual activity. |

| Despite the prevalence of syphilis worldwide, little is known about its manifestations when associated with other Sexually Transmitted Infections (STI), specifically the Human Papilloma Virus (HPV). Current epidemiological studies show that there is a high incidence of both diseases in ambulatory clinics all over Brazil. This study aims to estimate the incidence of syphilis - HPV co-infections, among patients from the STI ambulatory clinic at the Santa Casa da Misericórdia Hospital, Rio de Janeiro, Brazil. Two-hundred and seven patients were seen in the clinic between March and December 2005, of which 113 (54.6%) sought care for an HPV infection. Blood samples were taken from all patients to check syphilis serology using the flocculation and the... |

| BACKGROUND: The occurrence of syphilis and HIV-1 infections during pregnancy are major risks to the fetus due to mother-to-child transmission (MTCT). OBJECTIVES: To determine peripartum seroprevalence and risk factors of syphilis and HIV-1 infection among pregnant women in Salvador, Brazil, and the rate of HIV-1 MTCT. METHODS:Cross-sectional study of pregnant women who were admitted for delivery in a reference maternity hospital between May 2008 and March 2009 was conducted. Women were screened for HIV-1 infection and syphilis, and interviewed regarding demographic, behavioral and obstetric data. Newborns to HIV-infected mothers were tested by b-DNA and DNA-PCR to detect HIV-1. RESULTS: A total 3300/8516 women were evaluated. Mean age was 25.8 ± 7.3 years.... |

| Three recombinant antigens of Treponema pallidum Nichols strain were fused with GST, cloned and expressed in Escherichia coli, resulting in high levels of GST-rTp47 and GST-rTp17 expression, and supplementation with arginine tRNA for the AGR codon was needed to obtain GST-rTp15 overexpression. Purified fusion protein yields were 1.9, 1.7 and 5.3 mg/l of cell culture for GST-rTp47, GST-rTp17 and GST-rTp15, respectively. The identities of the antigens obtained were confirmed by automated DNA sequencing using ABI Prism 310 and peptide mapping by Finningan LC/MS. These recombinant antigens were evaluated by immuno-slot blot techniques applied to 137 serum samples from patients with a clinical and laboratory diagnosis of syphilis (61 samples), from healthy... |

| Antiphospholipid antibodies (aPL) are a heterogeneous group of antibodies that are detected in the serum of patients with a variety of conditions, including autoimmune (systemic lupus erythematosus), infectious (syphilis, AIDS) and lymphoproliferative disorders (paraproteinemia, myeloma, lymphocytic leukemias). Thrombosis, thrombocytopenia, recurrent fetal loss and other clinical complications are currently associated with a subgroup of aPL designating the antiphospholipid syndrome. In contrast, aPL from patients with infectious disorders are not associated with any clinical manifestation. These findings led to increased interest in the origin and pathogenesis of aPL. Here we present the clinical features of the antiphospholipid syndrome and review the... |
