PrevalÃncia de co-infecÃÃo pelos vÃrus linfotrÃpico de cÃlulas T humanas do adulto â HTLV e vÃrus da imunodeficÃncia adquirida â HIV, no Cearà / Prevalence of co-infection with human T-lymphotropic adult - HTLV and acquired immunodeficiency virus - HIV, CearÃ

Leila Maria Machado Bezerra 16 July 2003 (has links)
No Brasil vÃrios estudos demonstraram prevalÃncia de coinfecÃÃo pelos vÃrus linfotrÃpico de cÃlulas T humanas â HTLV e vÃrus da imunodeficiÃncia humana â HIV, dentre grupos especÃficos de indivÃduos, que variou de 0,58% a 11,4%. O CearÃ, segundo dados anteriores, representa dentre os Estados do Nordeste, uma Ãrea de baixa endemicidade para a infecÃÃo pelos vÃrus HTLV. Este estudo tem por objetivo estudar aspectos clÃnicos e epidemiolÃgicos da coinfecÃÃo por HTLV e HIV, em Hospital de referÃncia para tratamento de pacientes com HIV do CearÃ. Este estudo à descritivo, do tipo transversal, realizado no perÃodo de maio de 2001 a outubro de 2002. Foram colhidas 420 amostras de sangue de pacientes soropositivos ao HIV, confirmados por Elisa e Western Blot que posteriormente foram testadas para HTLV-I/II, no Centro de Hematologia do Cearà â HEMOCE. Entrevistou-se 337 pacientes e pesquisou-se 165 prontuÃrios mÃdicos para obtenÃÃo de informaÃÃes referentes à dados sÃcio-econÃmicos, fatores de risco para HTLV, prÃticas sexuais e aspectos clÃnicos. Os resultados revelaram valor de soroprevalÃncia geral de 0,95%, distribuÃdos em 0,23% de HIV-HTLV-I e 0,47% de HIV-HTLV-II, seguido de 01 (0,23%) amostra com sorologia indeterminada. NÃo foi evidenciada concomitÃncia de infecÃÃo pelos vÃrus HTLV-I e HTLV-II. A populaÃÃo estudada concentrou maior nÃmero de pacientes na faixa etÃria de 30 a 39 anos, era predominantemente de baixa renda (67,6%), menor grau de escolaridade (44,8%) e constituÃda na sua maioria por heterossexuais (67,8%). Quanto Ãs manifestaÃÃes clÃnicas pesquisadas em 119 indivÃduos, 105 (88,2%) manifestaram doenÃa intercorrente e 14 (11,8%) foram assintomÃticos, sendo 111 (93,27%) com definiÃÃo para diagnÃstico de AIDS. Um percentual elevado dos entrevistados amamentou (38,5%), sendo baixa a exposiÃÃo ao uso de tatuagem (12,2%) e a transfusÃo de sangue (15,9%). Foi notada que a escassez no uso de drogas intravenosas (4,8%), um menor nÃmero de negros (5,6%) e maior nÃmero de preferÃncia heterossexual (67,8%), poderiam ser os principais fatores apontados como responsÃveis pela baixa prevalÃncia encontrada em nosso Estado. / Several studies carried out in Brazil have shown a serum-prevalence rate of HIV / HTLV (Human Immunodeficiency - virus / Human T-Lymphotropic virus) co-infection of 0.58% to 11.4% among specific groups of individuals. Based on previous data, the State of Cearà is considered an area of low HTLV prevalence in the northeastern Brasil. This study evaluated the clinical and epidemiological aspects of the HIV / HTLV co-infection in a reference hospital for the treatment of HIV infected patients in CearÃ. A descriptive, cross sectional study was performed, in the period of May of 2001 to October of 2002. Blood samples were randomly collected from 420 HIV-positive patients, through Elisa and Western Blot tests, that later were serologically tested for HTLV-I/II in the Hematological Center of Cearà - HEMOCE. Interviews were done in 337 patients and 165 files were searched for socio-economic, risk factors for HTLV, sexual practice and clinical aspects. The results confirmed a general seroprevalence value of 0.95%, distributed as 0.23% of HIV-HTLV-I and 0.47% of HIV-HTLV-II, followed by one (0.23%) sample of undetermined serology. Concomitant infection was not evidenced by the viruses HTLV-I and HTLV-II. The population studied was more frequently 30 to 39 years old, had predominantly lower income (67.6%) and educational (44.8%) levels and were heterosexual mainly (67,8%). In 119 patients evaluated, 105 (88.2%) complained of HIV-related diseases, 14 (11.8%) were asymptomatic and 111 (93.3%) were diagnosed with AIDS. An elevated percentage was breast fed (38.5%), few had had tattoos (12.2%), and also did receive blood products (15,9%). The scarce use of intravenous drugs (4.8%), the few numbers of black individuals (5.6%) and higher numbers of heterosexuals (67.8%), were pointed as possible reasons for the low HTLV prevalence found in this research.
