Resumo: | We conducted a molecular epidemiological study to investigate HIV-1 strains in Rio Grande, southern Brazil, searching for an association with transmission mode and risk behavior. Patients (185) identified at an AIDS treatment reference Hospital, from 1994 to 1997, were included; from which 107 blood samples were obtained. Nested PCR was realized once for each sample; for amplified samples (69) HIV subtypes were classified using the heteroduplex mobility assay. Subtypes identified were B (75%), C (22%) and F (3%). All infections with C were diagnosed after 1994. Comparing patients with B and C, no differences were detected regarding demographic, clinical and laboratory characteristics; survival analysis did not reveal differences in HIV to AIDS evolution. A higher proportion of injecting drug users, IDU (not significant, p<.07) was found among those with C. This suggests that C may have been introduced in this area through IDU, and is being spread, probably by their sexual partners, to persons with other risk practices. |

Pacientes (185) identificados de 1994 a 1997, em um Hospital de referência para o tratamento da AIDS foram incluidos; amostras de sangue foram obtidas de 107. A reação em cadeia da polimerase (PCR) foi realizada uma única vez; nas amostras que amplificaram, (69) o subtipo foi classificado pelo ensaio de mobilidade do heteroduplex (HMA). Os subtipos de HIV identificados foram B (75%), C (22%) e F (3%). As infecções com C foram diagnosticadas após 1994. Pacientes infectados com B e C não mostraram diferenças (características demográficas, clínicas e laboratoriais); a análise de sobrevida não mostrou diferenças na evolução HIV-AIDS. Maior proporção de usuários de drogas injetáveis (UDI) (não significativa, p<0,07), foi identificada entre infectados com C. Este resultado sugere C ter sido introduzido nesta área através dos UDI,sendo transmitido pelos seus parceiros sexuais, a pessoas com outras práticas de risco.engMolecular epidemiologyHIV subtypesModes of transmissionEpidemiologia molecularSubtipos do HIVModos de transmissãoMolecular epidemiology of HIV-1 in Rio Grande, RS, Brazilinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da FURG (RI FURG)instname:Universidade Federal do Rio Grande (FURG)instacron:FURGORIGINALMolecular epidemiology of HIV-1 in Rio Grande, RS, Brazil.pdfMolecular epidemiology of HIV-1 in Rio Grande, RS, Brazil.pdfapplication/pdf47668https://repositorio.furg.br/bitstream/1/2491/1/Molecular%20epidemiology%20of%20HIV-1%20in%20Rio%20Grande%2c%20RS%2c%20Brazil.pdf08d898be09c40a63218a60d486922a85MD51open accessLICENSElicense.txtlicense.txttext/plain; charset=utf-81678https://repositorio.furg.br/bitstream/1/2491/2/license.txtd3be63d3b3eee02729709361dac69efeMD52open access1/24912019-12-12 10:36:13.696open accessoai:repositorio.furg.br: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ório InstitucionalPUBhttps://repositorio.furg.br/oai/request || http://200.19.254.174/oai/requestopendoar:2019-12-12T13:36:13Repositório Institucional da FURG (RI FURG) - Universidade Federal do Rio Grande (FURG)false |

Nested PCR was realized once for each sample; for amplified samples (69) HIV subtypes were classified using the heteroduplex mobility assay. Subtypes identified were B (75%), C (22%) and F (3%). All infections with C were diagnosed after 1994. Comparing patients with B and C, no differences were detected regarding demographic, clinical and laboratory characteristics; survival analysis did not reveal differences in HIV to AIDS evolution. A higher proportion of injecting drug users, IDU (not significant, p<.07) was found among those with C.
