Abandono do tratamento de tuberculose em co-infectados TB/HIV

Este estudo objetivou analisar os motivos que levam os pacientes coinfectados TB/HIV a abandonar o tratamento da TB e conhecer a conduta da equipe de saúde frente a esse abandono. A abordagem foi qualitativa. Utilizou-se a entrevista semiestruturada, aplicada a quarenta e cinco profissionais que atuam em uma Unidade de Referência no Pará. Após análise temática, foram construídas duas unidades: fatores relacionados aos doentes que dificultam adesão ao tratamento da TB; e fatores relacionados ao serviço que contribuem para o abandono. Mostrou-se, com relação aos pacientes, que a baixa condição socioeconômica foi o fator mais frequente que propicia o abandono. Também efeitos adversos dos medicamentos, uso de drogas lícitas, e pouca motivação pessoal facilitam esse desfecho. Quanto ao Serviço, as questões relacionadas à estrutura física, organização do processo de trabalho e acesso mostraram-se relevantes para não adesão. Os resultados apontam para a necessidade de alterar as práticas desenvolvidas nos Serviços.

Coexistencia de variantes HIV-1 com insercao dipeptidica no gene da transcriptase reversa

O objetivo desta comunicação foi descrever a detecção de coexistência de variantes HIV-1 com inserções de dois aminoácidos entre os códons 69 e 70 da transcriptase reversa. Tais variantes foram isoladas de paciente do sexo masculino, 16 anos de idade, em tratamento no interior do estado de São Paulo. Após confirmação de falha terapêutica, foi realizado teste de resistência a antirretrovirais, a partir do qual foram detectadas duas variantes contendo inserções dos aminoácidos Ser-Gly/Ser-Ala no códon 69 da transcriptase reversa, além da mutação T69S. Tais inserções possuem baixa prevalência, não foram relatadas em caráter de coexistência no Brasil e estão relacionadas com a resistência a múltiplas drogas, tornando o achado relevante do ponto de vista epidemiológico.

Late diagnosis and vulnerabilities of the elderly living with HIV/AIDS

Objective: To identify vulnerabilities of elderly people with HIV/AIDS and the trajectory that they follow until reaching the diagnosis of the disease. Method: Qualitative research conducted in specialized clinics in the state of Sao Paulo, from January to June 2011. Semi-structured interviews were conducted with 11 elderly people who were found to be infected with the virus at the age of 60 years or older. The interviews were analyzed using content analysis. Results: In this process four categories emerged, then analyzed with reference to the theoretical framework of vulnerability. Conclusion: Late diagnosis of HIV infection or AIDS among the elderly happens in the secondary or tertiary service. Issues related to sexual life of the elderly are only questioned by health professionals after the diagnosis, also the time that condom use becomes absolute. It is believed that the investigation of the vulnerability of the elderly to HIV/AIDS allows for carrying out appropriate interventions for this population.

A flow cytometry method for testing the susceptibility of Cryptococcus spp. to amphotericin B

Human fungal infections have increased at an alarming rate in recent years, particularly in immunocompromised individuals. Cryptococcosis is the second most prevalent systemic fungal infection worldwide, and the most prevalent systemic infection in immunocompromised individuals, representing more than 70% of cases. The incidence of cryptococcosis is high in people with HIV/acquired immunodeficiency syndrome (AIDS), with recent estimates indicating that there are one million cases of cryptococcal meningitis globally per year in AIDS patients. The aim of this research was to develop a rapid flow cytometric antifungal susceptibility test and to compare the results with the standard methods. A reference strain and clinical isolates of Cryptococcus neoformans and Cryptococcus gattii were tested for susceptibility to amphotericin B by flow cytometry using propidium iodide as indicator of viability. Flow cytometry (FC) results were compared with the minimum inhibitory concentration (MIC) values determined by microdilution. The antifungal activity of amphotericin B ranged from MICs of 0.06 to 2μg/ml for the 11 isolates studied. The same results were found by FC. The FC method allows same-day results, assisting in the selection of appropriate antifungal therapies. These results demonstrate an excellent correlation between FC and the classic methods of testing for susceptibility to antifungal agents. This rapid diagnosis method makes it possible to quickly administer effective therapeutic interventions, often saving lives.

HOPE IN HIV-POSITIVE WOMEN

The objective of this study was to assess the hope in the lives of HIV-positive women, using the Herth Hope Scale (HHS). Participants were 111 HIV-positive women who attended a referral outpatient clinic in Fortaleza-CE. From January to May 2009, interviews were held to collect biopsychosocial variables, and the HHS was applied. Data were analyzed using SPSS-8.0 and revealed an average hope index of 34.86, indicating that these women have little hope in life in view of their diagnosis of HIV. The scale item with the highest score was faith. This probably derives from the fact that Aids is incurable, transmissible and generates negative stigma, in addition to its relation with the idea of imminent death. In conclusion, measuring hope among HIV patients through the use of an instrument permits intervention assessment and planning, promoting assistance and motivation to live better and maintain a hopeful attitude.
