Doadores de sangue positivos em triagem sorológica para doença de Chagas no Acre: necessidade de adequação e orientação diagnóstica
(Universidade Federal do Pará, 2011-01-24) SILVA, Pablo Rodrigo de Andrade e; PÓVOA, Marinete Marins; http://lattes.cnpq.br/2256328599939923
This study, which involved 77,893 blood donors who attended for the first time the Blood Center of Acre, from January 1997 to December 2008, aimed to: 1) to identify individuals with positive serology for Chagas disease, 2) characterize clinically, individuals with positive serology for Chagas' disease and 3) properly orient individuals serologically positive for therapy advocated. The sample consisted of 91.6% of male patients, with an average age around 47, all residents of the state of Acre. Serological screening was performed with the application of the ELISA positive results with 102 of these, 12 were included and subjected to confirmatory testing, of whom 11 had confirmed the positive result. According to the evaluation of complementary exams (ECG, echocardiography and endoscopy), a donor had installed the cardiac and the other an indeterminate form of the disease. You must provide the confirmatory test for Chagas disease in the routine of blood banks in order to ensure timely referral to a qualified medical assistance to that blood donor who became Chagas’ patients.

Soroprevalência de anticorpos e padronização do teste ELISA sanduíche indireto para 19 tipos de arbovírus em herbívoros domésticos

The brazilian Amazon region maintains the largest variety of arboviruses and the state of Pará is responsible for 26% of this territory, so the major goal of this work was to determine the prevalence and distribution of HI antibodies to 19 domestic arbovirus in domestic herbivores in the state of Pará and to standardize an indirect sandwich IgG ELISA test to serum samples of equines, cattle, buffaloes and sheep. In all species studied and throughout the State of Pará a large prevalence of HI antibodies to all arbovirus analyzed was observed and SLEV, ILHV, EEEV, MAGV and WEEV, showed higher prevalence, where the SLEV was the most prevalent. Regarding the virus families HI antibodies to MAGV was the most prevalent Bunyaviridae in all species, the most prevalent Flaviviridae was SLEV in all species and in the family Togaviridae the EEEV was more prevalent in horses. In order to analyze the prevalence of HI antibodies by animal species was observed that horses did not show significant differences compared to buffaloes, however, showed significant difference compared to cattle and sheep; there was not observed significant difference between the ruminant species. Using sandwich indirect IgG ELISA a large number of crossed reactions were found. This enzymatic test can be used to detect IgG antibodies among families of arboviruses studied.

Soroprevalência e caracterização molecular do Vírus da imunodeficiência humana (HIV) e do Vírus linfotrópico de células T humanas (HTLV) em mulheres profissionais do sexo do Estado do Pará, Brasil

The Women’s Professional of the Sex (WPS) constitute a vulnerable population to the acquisition of sexually transmissible illnesses (STI) in virtue of the type of activity that they play. The present work had as objective to describe the serumprevalency of the infection and the molecular characterization of the HIV and the HTLV of WPS of the State of Pará, Brazil. Blood sample’s of 339 WPS were collected, being 105 proceeding from the city of Barcarena, 31 of the city of Augusto Correa, 98 of the city of Bragança and 105 of the city of Belém, in the period of April of 2005 the August of 2006. All the plasma samples had been tested for the presence of antibodies anti-HTLV-1/2 and anti-HIV-1/2, by means of the use of a immune enzimatic assay. The prevalence of the HIV-1 and the HTLV-1 in the studied population was of 2,36% and 1,77%, respectively. The amplification of the gene pro of the HIV-1 disclosed subtypes B and F, whereas the samples of HTLV, had been classified as HTLV-1 of the Cosmopolita subtype of the Transcontinental sub-group. It had a significant association of the infection for the HIV-1 with the age band, the number of partners per week and with the capricious use of condoms. However, the infection for the HTLV-1 alone showed significant association in relation to the capricious use of condom. The sexual relation was the most likely way of acquisition of the infection for the two viral agents, considering that the report of use of injective drugs was rare. Being thus, the WPS need bigger attention of the public agencies of health, specially in relation to the prevention and monitoring of transmissible agents by sexual pathways, as these can be important in the acquisition and dissemination of these agents.
