Much effort has been devoted to the identification of immunologically important antigens of Mycobacterium tuberculosis and to the combination of target antigens to which antibodies from serum of tuberculous patients could react specifically. We searched for IgG antibodies specific for antigens of 45 to 6 kDa obtained after sonication of the(More)
OBJECTIVE This study aimed to verify the association between human leukocyte antigens and the bcr-abl fusion protein resulting from t(9;22)(q34;q11) in chronic leukemia myeloid and acute lymphoblastic leukemia patients. METHODS Forty-seven bcr-abl positive individuals were evaluated. Typing was performed bymicrolymphocytotoxicity and molecular biological(More)
Two recombinant antigens and a crude bacterial antigen of a wild M. tuberculosis strain were used to detect specific IgG antibodies in sera from 52 patients with pulmonary tuberculosis, confirmed by an acid-fast smear and serum culture of these patients and that of 25 contacts. The patients were not infected with HIV. We evaluated the sensitivity and(More)
OBJECTIVES This study aimed to determine the frequency and antibody titers of nuclear dense fine and cytoplasmic patterns with possible clinical correlation. METHODS From 2007 to 2009, the results of 2,788 autoantibody serological tests were assessed by indirect immunofluorescence (IIF) at LAC-HUSM/UFSM, using as substrate HEp-2. RESULTS Among the(More)
We evaluated the performance of the ELISA technique in the detection of IgA antibodies against different Mycobacterium tuberculosis antigenic preparations in serum samples from 49 patients with pulmonary tuberculosis collected before and after the start of specific treatment. The controls consisted of serum samples from healthy patients without any prior(More)
PURPOSE to analyze the clinical and epidemiological profile, the outcome of pregnancy and the vertical transmission of human immunodeficiency virus (HIV)-infected pregnant women receiving prenatal care at the University Hospital of Santa Maria (HUSM). METHODS A prospective study was conducted on 139 HIV-infected pregnant women attended at the High-Risk(More)
The purpose of this study was to measure the level of anticardiolipin antibodies in preeclamptic pregnant women to verify a possible association between the presence of these antibodies and the development of the syndrome. A total of 36 pregnant women with preeclampsia and 19 women with normal pregnancy were evaluated. Anticardiolipin antibodies were(More)
This article seeks to analyze and update the epidemiological situation of meningitis caused by Haemophilus influenzae type b in the past 10 years in the state of Rio Grande do Sul (RS). It is a retrospective, descriptive study, which used the data notification system of meningitis and vaccination campaign coverage, stored in the Epidemiological TABNET(More)
