Na presente investigação, buscou-se pesquisar se o conceito de qualidade de vida, preconizado pela Organização Mundial de Saúde (OMS) poderia ser utilizado para pacientes com doença falciforme (DF), uma vez que se apresenta como um problema de saúde pública no país. Utilizou-se uma abordagem qualitativa com a seguinte questão norteadora na entrevista: "Para você o que é QV?". De acordo com o relato dos pacientes, procurou-se identificar a presença dos domínios físico, psicológico, nível de independência, relações sociais, meio ambiente e espiritualidade/crenças pessoais na representação da QV. Participaram do estudo 25 pacientes, dos quais 80% eram portadores da hemoglobina SS (HbSS) e 20% com hemoglobina SC (HbSC). A médiada idade encontrada foi de 33,3 anos, 56% eram do sexo feminino e 44% eram casados(as). Em relação à escolaridade, 44% atingiram até 11 anos de estudo e 56% até 8 anos. A DF representou, para 72%, impedimento para o trabalho, o que revela seu impacto negativo no desenvolvimento das habilidades laborais. Todos os domínios de QV preconizados pela OMS foram detectados no relato dos participantes: domínio físico em 84%, psicológico e relações sociais em 76%, nível de independência em 60%,meio ambiente em 52% e espiritualidade/crenças pessoais em 4% deles. Os aspectos referentes à multidimensionalidade e à subjetividade, apresentados no conceito de QV preconizado pela OMS, e representados pelos seus domínios, podem ser tomadoscomo norteadores de estudos que envolvam o conceito de QV em pacientes com DF.
This study aimed at investigating whether the concept of quality of life advocated by the World Health Organization can be applied to sickle cell patients, as this disease is an important public health problem in the country. A qualitative approach was utilized with the following guide question in the interview: "What is quality of life for you?" According to the patients' replies, the following domains were identified: physical, psychological, level of independence, social relationships, environment and spirituality/personal beliefs. Twentyfivepatients took part in the study, 80% had hemoglobin SS and 20% hemoglobin SC. The average age was 33.3 years old, 56% of the patients were women and 44% were married. In relation to schooling, 12% had concluded the 4th grade of elementary school and 24% completed high school. Sickle cell disease represented a barrier in respect to work for 72% of the patients, which demonstrates its negative impact on the development of the work capabilities ofthe individuals. All quality of life domains advocated by the WHO were present in the patients' replies: physical domain in 84%, psychological and social relationships in 76%, level of independence in 60%, environment in 52% and spirituality/personal believes in 4%. To conclude, the aspects referring to multidimensionality andsubjectivity, presented in the quality of life concept advocated by the WHO and represented by their domains, can be taken as a guide for studies which involve the quality of life in sickle cell patients.

Os vírus linfotrópicos de células T humana tipo 1 (HTLV-1) e tipo 2 (HTLV-2) foram os primeiros retrovírus identificados em humanos, em 1980 e 1982, respectivamente. O HTLV-1 é associado à leucemia/linfoma de células T do adulto (ATL) e mielopatia associada ao HTLV-1/ paraparesia espástica tropical (HAM/TSP). Tais vírus podem ser transmitidos por via vertical (mãe para criança) principalmente pela amamentação; por via sexual e via parenteral (usuários de drogas e transfusão de sangue e componentes). Nas áreas endêmicas, as transmissões vertical e sexual têm sido as principais vias para a disseminação da infecção por HTLV-1. Porém, a hemotransfusão parece ter importante participação na introdução do HTLV em populações não endêmicas. A via mais eficaz de transmissão transfusional do HTLV-1 é através de componentes celulares do sangue contaminado. No passado, isso ocorria principalmente através da transfusão de sangue não testado para o HTLV-1/2. Eficiência de transmissão transfusional da ordem de 60 por cento foi descrita nos primeiros trabalhos japoneses. Subseqüentemente, extremos de 13 por cento a 80 por cento foram descritos nos estudos retrospectivos realizados nos Estados Unidos. Tamanha variação na eficiência da transmissão transfusional foi influenciada pelos parâmetros: tipo do produto sangüíneo, tempo decorrido entre a coleta dos componentes celulares até seu uso transfusional e carga proviral do HTLV no doador. Estima-se que 4 por cento a 8 por cento dos receptores de unidades celulares infectados por HTLV-1 possam desenvolver HAM/TSP, sendo raros os casos descritos de ATL nestes receptores. "Look-back"é o termo usado em hemovigilância para um programa que notifica grupos de receptores de hemotransfusão, de seus riscos quanto à exposição a um agente infeccioso por ocasião de transfusão prévia. "Look-back targeted"é o programa para identificar receptores de unidades previamente doadas por doadores específicos e que subseqüentemente...
In 1980 and 1982, respectively human T-Lymphotropic virus type 1 (HTLV-1) and type 2 (HTLV-2) were the first retroviruses identified in human beings. HTLV-1 is associated with adult T cell leukemia/lymphoma (ATL) and HTLV-associated myelopathy/Tropical Spastic Paraparesis (HAM/TSP). These viruses can be transmitted vertically (from mother to child), mainly by breast feeding; by sexual relationships and parenteral drug delivery (intravenous drug users and transfusion of blood and blood components). In endemic areas, vertical and sexual transmission has been the principal manner of dissemination of HTLV-1 infection. However, blood transfusion seems to have an important role in introducing HTLV in non-endemic populations. The most efficient way of transmission of HTLV-1 is through cell components of contaminated blood. In the past, this occurred chiefly through blood transfusions not tested for HTLV-1. An efficiency of transfusion transmission of 60 percent was described in the first reports of Japanese research. Thereafter, extremes of 13 percent to 80 percent were described in retrospectives studies performed in the USA. Such variations in the efficiency of transmission by transfusions were influenced by parameters such as: blood product type, time spent from collection of the cell components until its transfusion and proviral load of the donor. It is estimated that about 4 to 8 percent of receptors of HTLV infected cell units can develop HAM/TSP, with ATL being rare in these receptors. Look-back is the term used in hemovigilance for a program that notifies blood transfusion receptors of the risks involved in exposure to infectious agents due to a preceding transfusion. "Targeted look-back"is the program used to identify receptors of blood units donated by specific individuals that subsequently have been identified as infected by a specific agent (for example HTLV). This involves identification of previous blood component units transfused...

Results of a HIV prevalence study conducted in hemophiliacs from Belo Horizonte, Brazil are presented. History of exposure to acellular blood components was determined for the five year period prior to entry in the study, which occurred during 1986 and 1987. Patients with coagulations disorders (hemophilia A = 132, hemophilia B = 16 and coagulation disorders other than hemophilia = 16) were transfused with liquid cryoprecipitate, locally produced, lyophilized cryoprecipitate, imported from Säo Paulo (Brazil) and factor VIII and IX, imported from Rio de Janeiro (Brazil), Europe, and United States. Thirty six (22%) tested HIV seropositive. The univariate and multivariate analysis (logistic model) demonstrated that the risk of HIV infection during the study period was associated with the total units of acellular blood components transfused. In addition, the proportional contribution of the individual components to the total acellular units transfused, namely a increase in factor VIII/IX and lyophilized cryoprecipitate proportions, were found to be associated with HIV seropositivity. This analysis suggest that not only the total amount of units was an important determinant of HIV infection, but that the risk was also associated with the specific component of blood transfused
