Abstract Acute lymphoblastic leukemia (ALL) is the most common hematologic malignancy in children in childhood. Single-nucleotide polymorphism (SNPs) in key molecules of the immune system, such as Toll-like receptors (TLRs) and CD14 molecules, are associated with the development of several diseases. However, their role in ALL is unknown. A case–control study was performed with 152 ALL patients and 187 healthy individuals to investigate the role of SNPs in TLRs and the CD14 gene in ALL. In this study, TLR6 C > T rs5743810 [OR: 3.20, 95% CI: 1.11–9.17, p = 0.003) and TLR9 C > T rs187084 (OR: 2.29, 95% CI: 1.23–4.26, p = 0.000) seems to be a risk for development of ALL. In addition, the TLR1 T > G rs5743618 and TLR6 C > T rs5743810 polymorphisms with protection against death (OR: 0.17, 95% IC: 0.04–0.79, p = 0.008; OR: 0.48, 95% IC: 0.24–0.94, p = 0.031, respectively). Our results show that SNPs in TLRs genes may be involved in the pathogenesis of ALL and may influence clinical prognosis; however, further studies are necessary to elucidate the role of TLR1, TLR4, TLR5, TLR6, TLR9 and CD14 polymorphisms in this disease.

Introduction The prevalence of human T-cell lymphotropic virus types 1 and 2 (HTLV-1/2) infection is heterogeneous across different populations. We tested the hypothesis that HTLV-1/2 infection occurs more often in dermatological patients. Methods A total of 1,091 patients from a tropical dermatology clinic were tested for HTLV-1/2. In parallel, 6865 first-time blood donors from the same geographic area were screened for HTLV-1/2; HTLV-1/2 positive blood donors underwent dermatological examinations. Results The prevalence of HTLV-1/2 in first-time blood donors was 0.14%. No co-occurrence of HTLV-1/2 infection and dermatological conditions was observed. Conclusions Our results challenge the hypothesis that HTLV-1/2 infection occurs more often in dermatological patients.

Diseases of the blood and blood-forming organs ,RC633-647.5 - Abstract
Background Associations between aplastic anemia and numerous drugs, pesticides and chemicals have been reported. However, at least 50% of the etiology of aplastic anemia remains unexplained.Design and Methods This was a case-control, multicenter, multinational study, designed to identify risk factors for agranulocytosis and aplastic anemia. The cases were patients with diagnosis of aplastic anemia confirmed through biopsy or bone marrow aspiration, selected through an active search of clinical laboratories, hematology clinics and medical records. The controls did not have either aplastic anemia or chronic diseases. A total of 224 patients with aplastic anemia were included in the study, each case was paired with four controls, according to sex, age group, and hospital where the case was first seen. Information was collected on demographic data, medical history, laboratory tests, medications, and other potential risk factors prior to diagnosis.Results The incidence of aplastic anemia was 1.6 cases per million per year. Higher rates of benzene exposure (≥30 exposures per year) were associated with a greater risk of aplastic anemia (odds ratio, OR: 4.2; 95% confidence interval, CI: 1.82–9.82). Individuals exposed to chloramphenicol in the previous year had an adjusted OR for aplastic anemia of 8.7 (CI: 0.87–87.93) and those exposed to azithromycin had an adjusted OR of 11.02 (CI 1.14–108.02).Conclusions The incidence of aplastic anemia in Latin America countries is low. Although the research study centers had a high coverage of health services, the underreporting of cases of aplastic anemia in selected regions can be discussed. Frequent exposure to benzene-based products increases the risk for aplastic anemia. Few associations with specific drugs were found, and it is likely that some of these were due to chance alone.

Objective: to analyze the epidemiological profile of brain death notifications. Method: this is a retrospective, analytical and descriptive study with a quantitative approach, carried out through the analysis of medical records and forms for opening the Brain Death protocol, identifying its sociodemographic, clinical aspects and aspects of the organ and tissue donation process. Result: there was a prevalence of males, with a mean age of 37.34 years. Regarding the cause of the coma, stroke presented a higher percentage, with subarachnoid hemorrhage as the most prevalent diagnosis. Transcranial doppler was the most widely used confirmatory test. When it comes to the effectiveness of the donation, it was observed that a higher percentage of non-donors, presenting logistical / structural / other problems as the main causes. Conclusion: it was identified the need to carry out continuing education to improve the records of health professionals in the medical records, the importance of sensitizing the population about the process of organ and tissue donation and updates of professionals in relation to the methods of maintaining the potential donor. Objetivo: analizar el perfil epidemiológico de las notificaciones de muerte cerebral. Método: este es un estudio retrospectivo, analítico y descriptivo con un enfoque cuantitativo, realizado a través del análisis de registros médicos y formularios para abrir el protocolo de Muerte Cerebral, identificando sus aspectos sociodemográficos, clínicos y aspectos del proceso de donación de órganos y tejidos. Resultado: hubo una prevalencia de varones, con una edad media de 37,34 años. En cuanto a la causa del coma, el accidente cerebrovascular presentó un porcentaje más alto, con la hemorragia subaracnoidea como el diagnóstico más frecuente. El doppler transcraneal fue la prueba confirmatoria más utilizada. Cuando se trata de la efectividad de la donación, se observó que un mayor porcentaje de no donantes, presentando problemas logísticos / estructurales / de otro tipo como las principales causas. Conclusión: se identificó la necesidad de llevar a cabo una educación continua para mejorar los registros de los profesionales de la salud en los registros médicos, la importancia de sensibilizar a la población sobre el proceso de donación de órganos y tejidos y las actualizaciones de los profesionales en relación con los métodos de mantenimiento del donante potencial. Objetivo: analisar o perfil epidemiológico de notificações de Morte Encefálica. Método: trata-se de um estudo retrospectivo, analítico e descritivo com abordagem quantitativa, realizado através da análise de prontuários e formulários de abertura de protocolo de Morte Encefálica, identificando seus aspectos sociodemográficos, clínicos e aspectos do processo de doação dos órgãos e tecidos. Resultado: verificou-se prevalência do sexo masculino, com média de idade de 37,34 anos. Em relação a causa do coma, o Acidente Vascular Cerebral apresentou maior percentual, sendo a Hemorragia Subaracnóidea como diagnóstico mais prevalente. O doppler Transcraniano foi o exame de confirmação mais utilizado. Em se tratando da efetivação da doação, observou-se que maior percentual de não doadores, apresentando problemas logísticos/estruturais/outros como causas principais. Conclusão: identificou-se a necessidade de realizar educação continuada para melhoria dos registros de profissionais da saúde nos prontuários, a importância de sensibilização da população quanto ao processo de doação de órgãos e tecidos e atualizações dos profissionais em relação aos métodos de manutenção do potencial doador.

LATIN is a multinational case–control study designed to identify risk factors for agranulocytosis and to estimate the incidence rate of the disease in some Latin American countries. Each study site in Brazil, Argentina and Mexico conducted an active search of agranulocytosis patients in hematology clinics and looked for possible associations with drug use. The overall incidence rate was 0.38 cases per 1 million inhabitant–years. Agranulocytosis patients more often took medications already associated with agranulocytosis than controls (p = 0.01), mainly methimazole (OR 44.2, 95% CI 6.8 to infinity). The population attributable risk percentage (etiologic fraction) was 56%. The use of nutrient supplements was more frequent among patients than controls (p = 0.03). Agranulocytosis seems to be very rare in Latin America. The lower than expected number of cases identified during the study period precluded estimation of the risk associated to individual drugs, with the exception of methimazol. However, this is the longest series of agranulocytosis cases ever gathered in Latin America, and information on drug exposures was collected prospectively. The conclusion is that drug-induced agranulocytosis does not seem to be a major public health problem in the study regions.
