Patients with an autoimmune condition are known to be at higher risk of developing other autoimmune disorders. Type 1 diabetes may be associated with additional autoimmune disorders including autoimmune thyroid disease. The aim of this study was to investigate the prevalence of thyroid autoantibodies in a group of children, adolescents, and young adults(More)
Chlamydia trachomatis (CT) is the most common bacterial cause of sexually transmitted disease. High-risk human papillomavirus (HR-HPV) is considered the main etiological agent for cervical neoplasia. Evidences showed that the presence of co-infection of CT and HR-HPV plays a central role in the etiology of cervical intraepithelial neoplasia (CIN) and(More)
The Human Papillomavirus (HPV) is a sexually transmitted organism associated with Cervical Intraepithelial Neoplasia (CIN) and cervical cancer, the second main cause of malignancy in women worldwide. The virus itself, however, is not enough to cause lesions on the cervix. Several studies suggest that some polymorphic sites changes the cytokines levels and(More)
In our study we investigated the possible role of MBL2 functional single nucleotide polymorphisms (SNPs) in the augmented susceptibility to develop other autoimmune diseases in presence of type 1 diabetes (T1D) in a group of Brazilian patients. Patients were stratified for the presence of autoimmune diseases known to be associated with T1D, such as(More)
This study compares the detection rates of Chlamydia trachomatis by two techniques, direct immunofluorescence (IMF) and real time polymerase chain reaction (PCR), in patients with and without intra-epithelial cervical lesions (SIL) in Recife. We conducted a transversal study involving 35 women with SIL and 35 without SIL attended at Ambulatório(More)
In our study, we identified a polymorphism (C-607A) in the promoter region of the IL-18 gene that shows different frequencies between human immunodeficiency virus (HIV)-1-infected children and healthy controls in a pediatric Brazilian population. The presence of the −607 C allele correlates to HIV-1 infection and confers an increased risk of infection in(More)
Patients with acute lymphoblastic leukemia presenting the immunophenotypic marker CD10+ (calla), usually has treatment profile good. The FLT3 molecular marker is listed as a prognostic factor, an important leukaemogenic marker in acute leukemias, also the polymorphism (G1082A) of the IL10 interleukin can to present pleiotropic effects in many diseases and(More)
To investigate the association of the IL-6 gene promoter polymorphism (-174 G/C) with SLE susceptibility and disease features in Brazilian patients, a case-control study of 80 lupus cases and 60 volunteer healthy women was performed. Genotyping was carried out by polymerase chain reaction and PCR product was digested by HSP92II restriction enzyme, being(More)
OBJECTIVE To evaluate agreement between 3 methods for screening anal intraepithelial lesions: anal cytology, anoscopy and human papillomavirus (HPV) detection by PCR. STUDY DESIGN This prospective, cross-sectional study screened 324 women with cervical neoplasia for anal neoplasia. Agreement between methods was calculated using the κ coefficient. (More)
OBJECTIVE To describe high-resolution anoscopy (HRA) findings and compare them with histopathology results. METHODS In a cross-sectional, observational study performed between December 2008 and December 2009, women receiving care at a center in Recife, Brazil, after a histopathologic diagnosis of cervical intraepithelial neoplasia or cervical cancer were(More)
