Histoplasmose InfecÃÃo em Pacientes HIV/AIDS Residentes na Cidade de Fortaleza, Cearà / Histoplasmosis infection in patients HIV / AIDS in the city of Fortaleza, CearÃFabricia Salvador Bezerra 15 May 2009 (has links)
CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel Superior / A histoplasmose à uma doenÃa causada por Histoplasma capsulatum var. capsulatum, nos seres humanos e em vÃrias outras espÃcies de animais. Trata-se de um fungo encontrado na natureza, principalmente em locais ricos em fezes de aves e morcegos: galinheiros sujos e abandonados, ambiente de cavernas, construÃÃes antigas, cÃpula de prÃdios e Ãrvores ocas. A infecÃÃo em humanos ocorre atravÃs das vias aÃreas superiores. Desde o inicio da epidemia de HIV na dÃcada de 80 à notada uma detecÃÃo crescente de histoplasmose disseminada em pacientes com aids de serviÃos de referÃncia em Fortaleza, sugerindo ser o Estado do Cearà uma Ãrea com elevada endemicidade para esse fungo. Este estudo teve o intuito de identificar a prevalÃncia de histoplasmose infecÃÃo em pacientes com HIV/aids, residentes na cidade de Fortaleza, CearÃ. Trata-se de um estudo transversal, descritivo e analÃtico, com uma amostra composta por 161 pacientes, acompanhados no ambulatÃrio de HIV/aids do Centro de Especialidades MÃdicas Josà de Alencar e que ao serem abordados, aceitaram participar do estudo. Para tanto, foi preenchido um formulÃrio, realizou-se teste intradÃrmico com histoplasmina (fase miceliana, fornecido pela Fiocruz-RJ) e coleta sanguÃnea para sorologia por imunodifusÃo (antÃgenos e anticorpos comerciais de Histoplasma capsulatum e Coccidioides immitis fornecidos pelo Centro Especializado em Micologia MÃdica-CEMM). A caracterizaÃÃo geral dos pacientes revelou que a maioria tinha, em mÃdia 35,11 anos, era do sexo masculino (76,40%; n=123), solteiros (67,70%, n=109), com renda familiar de no mÃximo trÃs salÃrios mÃnimos (81,99%; n=132) e com mais de 10 anos de estudo (44,10%; n=71). O tipo de ocupaÃÃo no passado obteve distribuiÃÃo variÃvel e atualmente parte do grupo (20,5%; n=33) encontrava-se desempregada. Um nÃmero de 137 pacientes (85,10%) relatou residir em casas, sendo Messejana o bairro de moradia mais citado pelos participantes (8,7%; n=14). Prevaleceram na amostra os pacientes com diagnÃstico recente de infecÃÃo por HIV, (66,46% identificados no ano de 2008). A prevalÃncia de histoplasmose infecÃÃo em pacientes com HIV/aids em Fortaleza foi de 12,42%. PresenÃa de galinheiro na vizinhanÃa atual do paciente (p=0,031); presenÃa de mangueira na residÃncia atual (p=0,023); atividade com terra no passado (p=0,021) e visitar sÃtio no passado (p=0,009), mostraram-se significantes para a infecÃÃo por Histoplasma capsulatum; jà o uso de medicaÃÃo anti-retroviral e o fato do paciente ter ou nÃo aids, nÃo influenciaram na reatividade à histoplasmina (ambos p=1,00). Pode-se concluir que Fortaleza constitui-se Ãrea com significativa prevalÃncia de histoplasmose infecÃÃo, levando-se em conta que a populaÃÃo estudada se referia a pacientes com supressÃo da resposta imune. O valor obtido aponta para a necessidade de identificaÃÃo dessas pessoas em risco para histoplasmose doenÃa e a implementaÃÃo de medidas profilÃticas naqueles susceptÃveis Ãs formas graves desta infecÃÃo. / Histoplasmosis is an infection disease caused by the fungus Histoplasma capsulatum var. capsulatum that can affect humans and several other animal. This fungus can be found in nature, mainly in places rich in bat and bird droppings: dirty and abandoned chicken coops, cave environments, old constructions, building domes and hollow trees. The infection in humans occurs through the upper airways. Since the HIV outbreak in the 1980s, it is noticed an increasing detection of disseminated histoplasmosis among aids patients assisted in reference clinics of Fortaleza, suggesting the Brazilian State of Cearà as an area with high endemicity related to this fungus. The purpose of this study is to identify histoplasmosis infection prevalence among HIV/aids-infected patients, who live in the city of Fortaleza, CearÃ. It is a transverse, descriptive and analytic study, with a sample of 161 patients observed at the HIV/aids ambulatory from Josà de Alencar Center of Medical Specialties, and when invited, agreed to participate. For this, they filled in a form, took an intradermal test with histoplasmin (mycelial phase, provided by Fiocruz â RJ), and had their blood collected to serology via immunodiffusion (commercial antigens and antibodies from Histoplasma capsulatum and Coccidioides immitis were provided by Immy Immunodiagnostics laboratory). The general characterization of patients revealed that, on average, most participants were 35,11 years old, men (76,40%; n=123), single (67,70%, n=109), with a maximum family income of three minimum salaries (81,99%; n=132), and having more than 10 years of education (44,10%; n=71). Their previous employment situation had a variable distribution, although the majority of the group is currently unemployed. A number of 137 patients (85,10%) live in houses, and Messejana was the most informed quarter by the participants (8,7%; n=14). The year of 2008 had the most frequent HIV diagnoses among patients, with 66,46% (n=107). The prevalence of histoplasmosis infection among HIV/aids-infected patients, who live in the city of Fortaleza, was 12,42%. Some variables, such as the presence of chicken coops in the patientâs current neighborhood (p=0,031), the presence of mango trees in the current residence (p=0,023), dealing with soil in the past (p=0,021) and visiting small farms in the past (p=0,009) proved to be significant to the Histoplasma infection. However, the use of antiretroviral medication and having or not AIDS did not influence the reactivity to histoplasmin (both p=1,000). It can be concluded that Fortaleza constitutes an area with significant prevalence of histoplasmosis infection, considering that the analyzed population referred to people with suppression of the immune response. This result points out the necessity of identifying patients at risk for histoplasmosis, and also of implementing prophylactic measures on those susceptible to the severe forms of this disease.
