ABSTRACT

Resumen Introducción: La Enfermedad de Chagas también conocida como Tripanosomiasis americana es un problema de salud pública. Se calcula que en el mundo hay entre 6 y 7 millones de personas infectadas por Trypanosoma cruzi, la mayoría de ellas en América Latina. Objetivo: Identificar la prevalencia de infección por Trypanosoma cruzi en donantes de un banco de sangre del departamento de Boyacá 2016-2018. Materiales y métodos: Estudio descriptivo retrospectivo realizado en 25.920 donantes de sangre del departamento de Boyacá. La fuente de información fue secundaria. Se determinó la prevalencia de la infección por Trypanosoma cruzi y se compararon según sexo, grupo etario y tipo de donante a través de análisis de frecuencias. Resultados: Se evaluaron 9187 donantes durante el año 2016; 8517 en el 2017 y 8216 en el 2018, de los cuales 56,1% eran de sexo femenino y 43,9% masculino. La prevalencia de la infección por Trypanosoma cruzi fue 0,17 % en la tamización y 0,08 % con las pruebas confirmatorias de las cuales el 70,0% eran mujeres, el 85,0% donantes voluntarios por primera vez, el rango de edad en el que se presentó mayor prevalencia de este marcador serológico fue de 41 a 50 y de 51 a 65 años con un 35,0% cada uno . La prevalencia de la infección de Chagas presentó asociación estadísticamente significativa con la edad (p < 0,05). Conclusiones: Los bancos de sangre resultan ser una de las fuentes de información disponibles para monitorear el comportamiento de la enfermedad de Chagas y evaluar la toma de decisiones en salud pública, teniendo en cuenta que la enfermedad se caracteriza de manera asintomática y sin compromiso clínico en la mayoría de los casos.


Abstract Introduction: Chagas Disease, also known as American Trypanosomiasis, is a public health problem. It is estimated that in the world there are between 6 and 7 million people infected with Trypanosoma cruzi, most of them in Latin America. Objectives: To identify the prevalence of Trypanosoma cruzi infection in donors from a blood bank in the department of Boyacá 2016-2018. Materials and methods: Retrospective-descriptive study carried out in 25,920 blood donors from the department of Boyacá (Colombia). The source of information was secondary. The prevalence of Trypanosoma cruzi infection was determined and compared according to sex, age group and type of donor through frequency analysis. Results: 9187 donors were evaluated during 2016; 8,517 in 2017 and 8,216 in 2018, of which 56.1% were female and 43.9% male. The prevalence of Trypanosoma cruzi infection was 0.17% in screening and 0.08% with confirmatory tests of which 70.0% were women, 85.0% first-time volunteer donors, the range of The age at which the highest prevalence of this serological marker was found was 41 to 50 and 51 to 65 years with 35.0% each. The prevalence of Chagas infection showed a statistically significant association with age (p <0.05). Conclusions: Blood banks turn out to be one of the sources of information available to monitor the behavior of Chagas disease and evaluate decision-making in public health, taking into account the characteristics of the disease in which the majority of cases they are asymptomatic and without clinical compromise.

ABSTRACT

OBJECTIVE@#To explore the molecular basis of two individuals with weak D variant of the Rh blood type.@*METHODS@#Routine serological testing was carried out to detect the D, C, c, E and e antigens of the Rh blood group. The D antigen was further detected with an indirect antiglobulin test. The presence of Rhesus box was detected by PCR to determine the homozygosity of the RHD gene.@*RESULTS@#Both samples were determined as weak D phenotype by the indirect antiglobulin test. DNA sequencing revealed that case 1 harbored a heterozygous 208C>T variant in exon 2 and a heterozygous 1227G>A variant in exon 9; while case 2 harbored homozygous 779A>G variants of exon 5 of the RHD gene. Case 1 was determined as RHD+/RHD+, while case 2 was determined as RHD+/RHD-. The two samples were respectively named as weak D type 122 and weak D type 149 based on the rules of Rhesus Base Nomenclature.@*CONCLUSION@#D negative blood donors should subject to indirect antiglobulin testing and molecular analysis for safer transfusion.

ABSTRACT

OBJECTIVE@#To analyze the polymorphism of the HPA1-5,15 system of the donors in Zhangjiakou area.@*METHODS@#DNA was extracted from the blood samples of the donors, PCR- SSP method was used to divide HPA1-6, 15 genotype. The gene frequency and genotype frequency were calculated, compared with the difference and regiahal specificity of the populations in our country and foregiens was compared other populations.@*RESULTS@#The gene expression in the HPA-1, HPA-2 and HPA-4 systems were all homozygous aa, and the donors who expressed homozygous bb was not exessed. Among them, one heterozygous ab expression was found in both HPA-1 and HPA-4 systems (1%), and 14 cases of heterozygous ab expression were found in HPA-2 system (14%). The gene expression in the HPA-5 system was mainly homozygous aa (98%), and a very few expressed homozygous bb (2%) was found. The degree of heterozygosity of gene expression in the HPA-3 and HPA-15 systems was relatively high. The proprotion of the expression of aa, ab and bb in the HPA-3 system was respectively 46%, 40% and 14%, the proprotion of the expression of aa, ab and bb in the HPA-15 system was respectively 21%, 64% and 15%.@*CONCLUSION@#The gene frequency of platelet-specific antigen HPA1-5,15 system in zhangjiakou region shows local characteristics. The heterozygosity degree of gene expression in the HPA-3 and HPA-15 systems are both high, suggesting that they are more likely to result in alloimmunization and ineffective platelet transfusion, which should be pays attention to.

ABSTRACT

Resumo Objetivo: Avaliar os efeitos da música sobre a ansiedade-estado, parâmetros fisiológicos e laboratoriais, em doadores de sangue. Métodos: Ensaio clínico randomizado, duplo-cego, realizado em um Hemocentro Regional, localizado no interior de Minas Gerais. Participaram do estudo 126 doadores de sangue, divididos aleatoriamente em dois grupos, sendo grupo experimental (intervenção musical antes da doação de sangue) e grupo controle (rotina padrão). Utilizou-se para a avaliação dos escores de ansiedade-estado, o Inventário de Ansiedade Traço-Estado (IDATE). A intervenção musical constitui-se de um repertório de músicas eruditas aplicadas através de fones de ouvidos, por aproximadamente 26 minutos. Para as variáveis quantitativas empregou-se análises descritivas, para análise das diferenças entre os escores de ansiedade-estado, frequência cardíaca e respiratória, utilizou-se Teste t Student e, Teste não paramétrico de Mann-Whitney para avaliar a diferença entre os valores de pressão arterial, saturação de oxigênio e níveis de cortisol. Resultados: O grupo submetido à intervenção musical não apresentou redução estatisticamente significativa dos escores de ansiedade-estado (p=0,31). Entretanto, observou-se reduções significativas na frequência cardíaca (p=0,006), frequência respiratória (p=0,007) e níveis de cortisol sanguíneo (p<0,001). Conclusão: A música não reduziu os níveis de ansiedade-estado. Contudo, foi possível demonstrar a eficácia da intervenção na redução de parâmetros fisiológicos e laboratoriais, os quais apresentam-se alterados frente a situações ansiogênicas.


Resumen Objetivo: Analizar los efectos de la música sobre la ansiedad-estado, parámetros fisiológicos y de laboratorio en donantes de sangre. Métodos: Ensayo clínico aleatorizado, doble ciego, realizado en un centro de donación de sangre regional, ubicado en el interior del estado de Minas Gerais. Participaron en el estudio 126 donantes de sangre, divididos aleatoriamente en dos grupos: un grupo experimental (intervención musical antes de la donación de sangre) y un grupo de control (rutina normal). Para analizar la puntuación de la ansiedad-estado, se utilizó el Cuestionario de Ansiedad Estado Rasgo (IDATE). La intervención musical estaba compuesta por un repertorio de música erudita aplicada con auriculares, durante 26 minutos aproximadamente. Para las variables cuantitativas, se emplearon análisis descriptivos. Se utilizó el test-T Student para analizar las diferencias entre la puntuación de la ansiedad-estado, la frecuencia cardíaca y respiratoria y la prueba no paramétrica de Mann-Whitney para analizar la diferencia entre los valores de presión arterial, saturación de oxígeno y niveles de cortisol. Resultados: El grupo sometido a la intervención musical no presentó reducción estadísticamente significativa en la puntuación de la ansiedad-estado (p=0,31). Sin embargo, se observaron reducciones significativas en la frecuencia cardíaca (p=0,006), frecuencia respiratoria (p=0,007) y niveles de cortisol sanguíneo (p<0,001). Conclusión: La música no redujo los niveles de ansiedad-estado. No obstante, fue posible demostrar la eficacia de la intervención para la reducción de parámetros fisiológicos y de laboratorio, que se presentan alterados ante situaciones ansiógenas.


Abstract Objective: To evaluate the effects of music on state-anxiety, physiological and laboratory parameters in blood donors. Methods: Randomized, double-blinded clinical trial, conducted in a regional blood bank, located in the interior of the state of Minas Gerais, Brazil. In total, 126 blood donors participated in the study, randomly divided into two groups, being one experimental group (musical intervention before blood donation) and one control group (standard routine). To assess the state-anxiety scores, the State-Trait Anxiety Inventory (STAI) was used. The musical intervention consists of a repertoire of classical songs played through headphones, lasting approximately 26 minutes. For the quantitative variables, descriptive analyses were used to analyze the differences between state-anxiety, heart rate and respiratory rate, Student's t- test and Mann-Whitney's nonparametric test to evaluate the difference between blood pressure, oxygen saturation and cortisol levels. Results: The group submitted to musical intervention did not present a statistically significant reduction in state-anxiety scores (p = 0.31). Nevertheless, significant reductions in heart rate (p=0.006), respiratory rate (p=0.007) and blood cortisol levels (p<0.001) were observed. Conclusion: Music did not reduce the state-anxiety levels. We were able to demonstrate the effectiveness of the intervention in reducing physiological and laboratory parameters though, which are altered in the face of anxiogenic situations.

ABSTRACT

Introdução: Portadores do traço falciforme podem doar sangue, porém requerem maior atenção ao direcionamento da sua transfusão. Considerando o perfil étnico- racial da região sul do Brasil, o presente artigo teve como objetivo analisar o perfil e a prevalência de Hemoglobina S em um hemocentro público de Porto Alegre. Métodos: Estudo transversal retrospectivo realizado através de uma pesquisa em banco de dados cadastrais e de resultados de testes imunológicos no período de janeiro de 2015 a dezembro de 2019. Resultados: Foram obtidos um total de 8.2363 registros cadastrais e 6.7184 testes imunológicos. Dos testes, 467 foram positivos para Hemoglobina S de 134 doadores distintos. O percentual de Hb S positiva apresentou uma média de 0,7% anual entre todos os doadores. Entre doadores autodeclarados "Negros" a prevalência é de 0,92% e "Caucasianos" é de 0,13%. Conclusão: Os dados corroboram com a literatura, porém o espectro social que abrange as denominações "Caucasiano Brasileiro" e "Mestiço" permanecem em questionamento dentro da relevância do marcador étnico da Hemoglobina S no Rio Grande do Sul.

Introduction: People with sickle cell trait can donate blood, but special attention should be paid to the transfusion recipient. Considering the ethnic-racial profile of Southern Brazil, this article aimed to analyze the profile and prevalence of hemoglobin S in a public blood bank in Porto Alegre. Methods: A quantitative, retrospective, and cross-sectional study was conducted to assess the profile of blood donors positively screened for hemoglobin S from January 2015 to December 2019 in a public blood bank in Southern Brazil. Results: A total of 82,363 records and 67,184 immunohematological tests were obtained. Regarding the tests, 467 were positive for hemoglobin S among 134 different donors. The percentage of positive hemoglobin S has remained stable over the years, with an annual average of 0.7%. The prevalence of self-reported "black" and "Brazilian Caucasian" blood donors was 0.92% and 0.13%, respectively. Conclusions: The data are in accordance with the literature; however, the social spectrum that comprises the terms "Brazilian Caucasian" and "mixed-race" remains in question regarding the relevance of the ethnic marker of hemoglobin S in Southern Brazil.

ABSTRACT

Introdução: A doação de sangue é um ato capaz de salvar vidas. Quando a triagem sorológica é positiva, a bolsa de sangue é descartada. Este trabalho teve como objetivo avaliar a prevalência de descarte de bolsas de sangue em razão da positividade dos testes de triagem para sífilis. Métodos: Foi realizado um estudo epidemiológico observacional, com avaliação transversal e da tendência temporal da positividade do VDRL de acordo com as variáveis epidemiológicas, a partir de dados coletados no banco de sangue do Hemocentro de Sergipe das doações ocorridas de 1 de janeiro de 2007 a 31 de dezembro de 2018. Resultados: Do total de 308.953 doações de sangue, 4.594 bolsas (1,48%) foram descartadas devido a positividade para sífilis. A positividade foi significativamente maior no sexo masculino (OR = 1,14). Houve aumento significativo da prevalência com o aumento da faixa etária, de 0,63% (IC95% 0,51-0,760 em menores de 20 anos até 4,54% (IC95% 3,88-5,30) em pessoas com 60 anos e mais. Entre o período de 2007-2011 foi identificada uma tendência de crescimento da soroprevalência para sífilis (APC = 31,4) seguida pela estabilização do número de descarte de bolsas nos últimos anos. Discussão: O estudo identifica que, apesar de ter havido um aumento significativo no período inicial, a tendência foi de estabilidade nos últimos anos avaliados. É importante destacar a falta de um exame que indique concretamente a presença ativa da sífilis, pois todos os testes podem permanecer como cicatrizes por longos períodos, mesmos em pessoas com o tratamento adequado.

Introduction: Blood donation is an act that can save lives. When serological screening is positive, the blood bag is discarded. This study aimed to assess the prevalence of blood bag disposal due to positive screening tests for syphilis. Methods: An observational epidemiological study was carried out, with cross-sectional temporal trend assessment of VDRL positivity according to epidemiological variables, based on data collected in the blood bank of the Sergipe Blood Center, from the donations that occurred from 1 st January, 2007 to December 31 st , 2018. Results: Of the total of 308,953 blood donations, 4,594 bags (1.48%) were discarded due to positive serology for syphilis. Positivity was significantly higher in males (odds ratio = 1.14). There was a significant increase in prevalence with age, from 0.63% (95% CI 0.51-0.76) in individuals under 20 years old to 4.54% (95% CI 3.88-5.30) in those with 60 years and over. Between 2007-2011, a trend of increase in seroprevalence for syphilis was identified (annual percent change = 31.4), followed by stabilization in the disposal of bags in recent years. Discussion: Despite the increase in syphilis reported in society, the study identified that, although there was a significant increase in the initial period, it has been followed by stability in the last years evaluated. What is important is the lack of a test that in fact indicates the active presence of syphilis, since all tests can identify serological scars that remain for long periods, even in people with proper treatment.

ABSTRACT

Resumo O artigo tem por objetivo discutir as consequências das medidas de distanciamento social sobre a disponibilidade de sangue e a organização dos serviços hemoterápicos no início da pandemia de Covid-19 no Brasil. A partir do acesso às notícias publicadas no mês de abril de 2020 nos sites das Hemorredes estaduais do país e organizadas em matriz Excel, foram elaborados quadros-síntese e descrição de resultados. A situação crítica de abastecimento de sangue, em especial para alguns tipos sanguíneos, foi constatada em muitos estados, devido à circulação do novo coronavírus. A adoção de medidas de distanciamento social e a manutenção das demandas por transfusão para tratamentos, urgência e emergência, requereram a implantação e a implementação de estratégias e ações para reorganização dos serviços. Medidas de proteção foram incorporadas, fluxos alterados e rotinas estabelecidas. Este estudo evidencia o quanto a situação epidemiológica da Covid-19 e as medidas necessárias para o seu controle influenciaram sobre a situação dos estoques e disponibilidade de sangue, e, demandaram, mudanças na organização dos serviços hemoterápicos a fim de assegurar a proteção, mitigar os riscos de propagação do vírus e garantir o suprimento de sangue para o atendimento às necessidades do sistema de saúde.


Abstract The article aims to discuss the consequences of social distancing measures on the availability of blood and organization of blood therapy services at the beginning of the Covid-19 pandemic in Brazil. News published in April 2020 on the websites of the country's state Blood Service Networks were consulted and organized in an Excel spreadsheet, presented in summary charts, and descriptions of results were prepared. A critical situation of blood supply, especially of some blood types, has been observed in many states. This situation is influenced by the circulation of the new coronavirus. The adoption of social distancing measures associated with unchanged transfusion demands for outpatient, urgency and emergency care required the implementation of strategies and actions for the reorganization of the services. Protection measures were incorporated, flows were changed and new routines were established. This study shows the extent to which the epidemiological situation of Covid-19 and the necessary measures for its control influenced the stocks and availability of blood. Changes in the organization of blood therapy services were fundamental in order to ensure protection, mitigate the risks of spreading the virus, and ensure the blood supply to meet the needs of the health system.

ABSTRACT

Los posibles efectos adversos que se producen en transfusiones incompatibles ABO son un riesgo latente en el uso de concentrados de plaquetas grupo O, por lo que la titulación de hemolisinas anti-A/B constituye una de las estrategias para su prevención. El objetivo de este estudio fue determinar la frecuencia de títulos de hemolisinas de isotipos IgG e IgM anti-A/B en donantes de sangre. Se trató de un estudio descriptivo, transversal y aleatorio simple con un tamaño muestral de 308 muestras. Se aplicó la metodología en tubo, gel salino y anti-inmunoglobulina IgG y, mediante soluciones seriadas, se evidenció el título. Adicionalmente, se realizó una encuesta sobre los posibles factores de riesgo para el aumento de estos títulos. Se aplicó estadística descriptiva mediante el uso del software informático SPSS versión 22.0 y la relación entre variables independientes a través del análisis estadístico de Chi-cuadrado y, para establecer la concordancia de las lecturas visuales de las tarjetas de gel, se aplicó el índice kappa. Se determinó la existencia de hemolisinas de isotipo IgG e IgM anti-A/B de títulos superiores a 1/64. Existió una relación estadísticamente significativa entre embarazos y títulos de IgG anti-A/B >1/128 y el aumento de hemolisinas de isotipo IgM y la ingesta de probióticos. Los resultados demostraron la necesidad de implementar la titulación de hemolisinas previo a la transfusión de concentrados plaquetarios no isogrupo, por lo que se recomienda una investigación de riesgo-beneficio y el seguimiento de pacientes con transfusiones de concentrados plaquetarios incompatibles ABO.


The possible adverse effects that occur in incompatible ABO transfusions are a latent risk in the use of group O platelet concentrates, so the titration of anti-A/B hemolysins is one of the strategies for its prevention. The objective of this study was to determine the frequency of hemolysins titers IgG and IgM anti-A/B isotypes in blood donours. It was a simple randomized descriptive cross-sectional study with a sample size of 308 samples. The methodology was applied in tube, saline gel and anti-IgG anti-immunoglobulin and by means of serial solutions the title was verified. Additionally, a survey was conducted on the possible risk factors for the increase in securities. Descriptive statistics were used through the application of the SPSS version 22.0 software and the relationship between independent variables through the Chi-square statistical analysis and the kappa index was applied to match the visual readings of the gel cards. The existence of IgG and IgM anti-A/B isotype hemolysins of titers greater than 1/64 was determined. There was a statistically significant relationship between pregnancies and anti-A/B IgG titres>1/128; and the increase in IgM isotype hemolysins and probiotic intake. The results demonstrate the need to implement hemolysin titration prior to transfusion of non-isogroup platelet concentrates, so a risk-benefit investigation and follow-up of patients with transfusions of ABO incompatible platelet concentrates is recommended.


Os possíveis efeitos adversos que ocorrem em transfusões incompatíveis ABO são um risco latente no uso de concentrados de plaquetas do grupo O, portanto a titulação de hemolisinas anti-A/B é uma das estratégias para sua prevenção. O objetivo deste estudo foi determinar a frequência de títulos de hemolisinas de isotipos IgG e IgM anti-A/B em doadores de sangue. Trata-se de um estudo descritivo transversal aleatório simples, com tamanho de amostra de 308 amostras. A metodologia foi aplicada em tubo, gel salino e anti-imunoglobulina IgG e utilizando soluções em série, o título foi verificado. Além disso, foi realizada uma pesquisa sobre os possíveis fatores de risco para o aumento destes títulos. A estatística descritiva foi utilizada através da aplicação do software informático SPSS versão 22.0 e a relação entre variáveis independentes por meio da análise estatística do qui-quadrado e, para estabelecer a concordância com as leituras visuais dos cartões de gel, o índice kappa foi aplicado. Foi determinada a existência de hemolisinas de isotipo IgG e IgM anti-A/B de títulos maiores que 1/64. Existiu uma relação estatisticamente significante entre gestações e títulos de IgG anti-A/B>1/128; e o aumento de hemolisinas do isotipo IgM e a ingestão de probióticos. Os resultados demonstram a necessidade de implementar a titulação da hemolisina antes da transfusão de concentrados de plaquetas não isogrupo, por isso, recomenda-se uma investigação de risco-benefício e acompanhamento de pacientes com transfusões de concentrados de plaquetas incompatíveis com ABO.

ABSTRACT

Introducción: La donación de sangre salva vidas, por lo que la seguridad de la sangre es lo más importante de todo el proceso. La localización demográfica conduce a tener causas específicas de diferimiento. Vivir en zonas altoandinas produciría cambios adaptativos hematológicos. Es por esta razón que resulta importante conocer las causas de rechazo y así poder reorientar los programas de promoción de donación de sangre. Objetivo: Determinar las causas de rechazo de donantes de sangre de un hospital del sur peruano a 3825 m. s. n. m. Métodos: Se realizó un estudio transversal, de corte retrospectivo, sobre las causas de rechazo de posibles donantes de sangre del Hospital III EsSalud, Juliaca. Se analizaron los registros de predonantes que fueron rechazados, desde enero del 2014 a diciembre del 2018. Los datos se analizaron en el programa STATA v.14. Resultados: De los posibles predonantes seleccionados (4057), 1699 (41,87 por ciento) fueron mujeres y 2358 (58,13 por ciento) fueron varones. Fueron diferidos 1458 (41,87 por ciento), los varones tuvieron la tasa de rechazo más alta 882 (60,49 por ciento) en comparación con las mujeres 576 (39,51 por ciento). La polieritrocitemia fue la causa más frecuente de rechazo 669 (45,8 por ciento). Conclusiones: La tasa de rechazo fue moderada (35,93 por ciento) y la principal causa, fue el hematocrito alto (68,4 por ciento), seguido por el bajo (6,8 por ciento).


Introduction: Blood donation saves lives. Blood safety is thus the most important factor throughout the whole process. Demographic location accounts for specific reasons for deferral. Living in high Andean areas causes adaptive hematological changes. Therefore, it is important to be aware of the reasons for deferral with a view to reorienting blood donation promotion programs. Objective: Determine the reasons for blood donor deferral in a Southern Peruvian hospital 3 935 m amsl. Methods: A retrospective cross-sectional study was conducted of the reasons for deferral of potential blood donors in EsSalud III Hospital in Juliaca. An analysis was performed of the records of pre-donors deferred from January 2014 to December 2018. The data were processed with the software STATA version 14. Results: Of the potential pre-donors selected (4 057), 1 699 (41.87 percent) were women and 2 358 (58.13 percent) were men. A total 1 458 (41.87 percent) were deferred. Men had the highest deferral rate with 882 (60.49 percent), whereas the rate for women was 576 (39.51 percent). Polyerythrocythemia was the most common reason for deferral with 669 (45.8 percent). Conclusions: The deferral rate was moderate (35.93 percent) and the main reason was high hematocrit (68.4 percent), followed by low hematocrit (6.8 percent)(AU)

ABSTRACT

Objetivo: Describir los hallazgos hematológicos en donantes preseleccionados a plaquetoferesis sanguínea en el Hospital Nacional Edgardo Rebagliati Martins (HNERM) de Lima, Perú. Materiales y métodos: Estudio de tipo observacional, descriptivo y transversal, realizado entre Mayo-Julio 2019. Se incluyeron hemogramas de donantes que resultaron ̈Aptos ̈ a la entrevista médica, con resultado ̈Negativo ̈ a marcadores serológicos y que fueron diferidos en donar por presentar alteración hematológica. Los datos fueron recolectados del sistema informático del servicio de medicina transfusional del HNERM. Se utilizó estadística descriptiva y analítica (U de Mann Whitney y Chi-cuadrado de Pearson) considerándose un valor p<0,05 como significativo. Resultados: Se analizaron los hemogramas de 330 donantes preseleccionados diferidos, entre los cuales el recuento absoluto de eosinófilos (14,2%), el hematocrito (14,2%) y el recuento de plaquetas (33,9%) fueron las de mayor presencia. Asimismo, en las observaciones la fórmula leucocitaria invertida (20,6%) fue la más frecuente. Además, se observó diferencia estadística significativa (p<0,05) entre la hemoglobina, el hematocrito, la hemoglobina corpuscular media (HCM) y la fórmula leucocitaria invertida de acuerdo al sexo del donante. Conclusiones: La alteración hematológica observada más frecuentemente en esta población fue la plaquetopenia. Además, algunos parámetros de la serie roja y la distribución leucocitaria en el hemograma estuvieron asociados con el género del donante. (AU)


Objective: To describe the hematological findings in preselected donors to blood plateletpheresis at the Edgardo Rebagliati Martins National Hospital (HNERM) in Lima, Peru. Materials and methods: Observational, descriptive and cross-sectional study, carried out between May-July 2019. Blood counts were included from donors that were ̈Approved ̈ to the medical interview, with a ̈Negative ̈ result for serological markers and that were deferred in donating for present hematological alteration. The data was collected from the computer system of the HNERM transfusion medicine service. Descriptive and analytical statistics (Mann Whitney's U and Pearsonʼs Chi-square) were used, considering a p<0.05 as significant. Results: The blood counts of 330 delayed preselected donors were analyzed, among which the absolute eosinophil count (14.2%), the hematocrit (14.2%) and the platelet count (33.9%) were those with the highest presence. Likewise, in observations, the inverted white blood cell formula (20.6%) was the most frequent. In addition, a statistically significant difference (p<0.05) was observed between hemoglobin, hematocrit, mean corpuscular hemoglobin (MCH) and the inverted leukocyte formula according to the sex of the donor. Conclusions: The hematological alteration most frequently observed in this population was plateletpenia. In addition, some parameters of the red series and the leukocyte distribution on the blood count were associated with the gender of the donor. (AU)

ABSTRACT

Introducción: Los sistemas sanguíneos ABO, Rh y Kell son lo más relevantes desde el punto de vista clínico por su inmunogenicidad y ser los principales causantes de reacciones hemolíticas. Objetivo: Determinar las frecuencias de los grupos sanguíneos ABO y Rh, y la frecuencia del antígeno Kell en pacientes y donantes de Costa Rica. Métodos: Durante el periodo de 2009 al 2018 se obtuvo de las bases de datos de los bancos de sangre de tres hospitales de adultos de Costa Rica, las frecuencias de los grupos sanguíneos ABO, Rh y Kell en muestras de donantes y pacientes. Para contrastar las frecuencias de cada grupo sanguíneo se realizó una prueba de independencia de variables Chi cuadrado, con el 95 por ciento de confianza. Los datos se analizaron con el paquete estadístico SPSS versión 23. Resultados: Las frecuencias de los grupos ABO en las muestras de donantes y pacientes mostraron diferencias pequeñas pero significativas. La frecuencia del fenotipo Rh D negativo fue más alta en pacientes (8,0 por ciento) que en donantes (6,1 por ciento). Se estimaron las frecuencias de los antígenos C (67,8 por ciento), c (80,5 por ciento), E (41,4 por ciento), e (94,4 por ciento) y K (3,1 por ciento) a partir de las muestras de los donantes. Conclusiones: Las estrategias de reclutamiento de donantes de sangre aumentan la frecuencia del fenotipo Rh negativo en donantes con respecto a los pacientes. Las estadísticas recopiladas demuestran un aumento en la frecuencia del grupo O en comparación con los últimos estudios relacionados. Finalmente, los otros antígenos presentaron pocas variaciones en comparación a estudios previos(AU)


Introduction: The ABO, Rh and Kell blood systems are the most relevant from the clinical point of view, due to their immunogenicity and because they are the main causes of hemolytic reactions. Objective: To determine the frequencies of ABO and Rh blood groups, and the frequency of the Kell antigen in patients and donors from Costa Rica. Methods: During the period from 2009 to 2018, the frequencies of ABO, Rh and Kell blood groups in donor and patient samples were obtained from the blood bank databases of three adult hospitals in Costa Rica. To contrast the frequencies of each blood group, a chi-square test of independence of variables was performed, with 95 percent confidence interval. The data were analyzed with the statistical package SPSS version 23. Results: The frequencies of ABO groups in donor and patient samples showed small but significant differences. The frequency of the negative Rh D phenotype was higher in patients (8.0 percent) than in donors (6.1 percent). The frequencies of the antigens C (67.8 percent), c (80.5 percent), E (41.4 percent), e (94.4 percent), and K (3.1 percent) were estimated from donor samples. Conclusions: Blood donor recruitment strategies increase the frequency of negative Rh phenotype in donors compared to patients. The statistics collected demonstrate an increase in the frequency of the O group compared to recent related studies. Finally, the other antigens did not show as much variation compared to previous studies(AU)

ABSTRACT

Resumen: Introducción: La sangre de cordón umbilical (SCU) como fuente para trasplante de células proge- nitoras hematopoyéticas (TPH) está bien establecida. Internacionalmente, menos del 10% de los TPH de SCU corresponde a donantes hermanos compatibles. Dentro de la red del Programa Infantil Nacional de Drogas Antineoplásicas (PINDA), existe desde enero 2004 un programa de donación dirigida de SCU para TPH. Pacientes y Método: Se diseñó un estudio observacional, retrospectivo, descriptivo, se revisaron el número y características de las unidades de SCU recolectadas en el PINDA y el número, características y evolución de los pacientes trasplantados con esas unidades entre enero de 2004 y octubre de 2018. Resultados: Sesenta unidades de SCU han sido recolectadas, de ellas 55 con registro completo. La mediana de volumen de las unidades almacenadas fue 74,8 ml (30,0-170,8), la mediana de células nucleadas totales 7,6 x 10e8 (2,0-21,1), mediana de células CD34+ 1,6 x 10e6 (0,2-11,6). Cuatro pacientes con leucemias de alto riesgo fueron trasplantados; mediana de segui miento es de 8 años. Todos desarrollaron complicaciones severas post TPH, uno de ellos falleció de recaída y los tres actualmente vivos presentan un Karnofsky/Lansky 100%. Conclusión: El programa ha permitido el trasplante de 4 pacientes que de otro modo no habrían tenido acceso a un donante. Este programa de donación dirigida puede ser considerado una primera etapa para el desarrollo de un banco público de sangre de cordón umbilical en Chile.


Abstract: Introduction: Cord blood (CB) as a source of Hematopoietic Stem Cells for Transplantation (HSCT) is well established. Worldwide, nonetheless, less than 10% of the CB HSCTs are performed with a match sibling donor. Since 2004, the Chilean National Childhood Cancer Program (PINDA) net work, has established a CB directed donation program for HSCT. Patients and Method: An obser vational, descriptive and retrospective study was designed to assess the number and characteristics of the CB units collected in the program as well as the number, clinical characteristics and follow-up of the patients who received an HSCT from those CB units between January 2004 and October 2018. Results: Sixty CB units have been collected; 55 of them with full records and stored. The median volume collected was 74.8 ml (30.0-170.8), the median number of total nucleated cells was 7.6 x 10e8 (2.0-21.1), and the median of CD34+ cells was 1.6 x 10e6 (0.2-11.6). Four high-risk leukemia patients received HSCT, all of them developed severe complications after transplantation and one patient died due to relapse. Those patients currently alive have a 100% Karnofsky/Lansky score. The median follow-up time was 8 years. Conclusion: The PINDA program has allowed 4 patients to be transplan ted who otherwise would not have had access to a donor. This directed donation program could be seen as a model for the development of a public cord blood bank in Chile.

ABSTRACT

Ante la emergencia nacional decretada por la pandemia de la enfermedad COVID-19, se ha presentado una considerable reducción de la asistencia de personas donantes voluntarias altruistas de sangre a la Red Nacional de Bancos de Sangre, lo cual a corto plazo, puede ocasionar un desabastecimiento de hemocomponentes que son vitales para la atención de emergencias, así como también en el tratamiento de pacientes con diversas enfermedades en la Red de Hospitales del Sistema Nacional Integrado de Salud. Con el propósito de facilitar que las personas que son donantes voluntarios, puedan asistir a los Bancos de sangre, se elaboran los presentes lineamientos en los cuales se establecen los mecanismos para facilitar el traslado de los donantes, así como también se brindan las indicaciones a seguir por los Bancos de Sangre del Sistema Nacional Integrado de Salud


Given the national emergency decreed by the COVID-19 pandemic, there has been a considerable reduction in the assistance of voluntary altruistic blood donors to the National Network of Blood Banks, which in the short term, may cause a shortage of blood components that are vital for emergency care, as well as in the treatment of patients with various diseases in the Hospital Network of the National Integrated Health System. With the purpose of facilitating that people who are voluntary donors, can attend the blood banks, these guidelines are prepared in which the mechanisms to facilitate the transfer of donors are established, as well as the instructions to follow. by the Blood Banks of the National Integrated Health System

ABSTRACT

El uso de los componentes sanguíneos se ha vuelto muy importante para el manejo clínico de diversas patologías, sin embargo, no está exento de complicaciones, una de ellas son las infecciones transmisibles por transfusión (ITT). En las últimas décadas el riesgo de ITT se ha reducido eficazmente gracias a la pesquisa de marcadores serológicos en los donantes. El objetivo del trabajo fue determinar la seroprevalencia de marcadores para infecciones transmitidas por transfusión en donantes de un Hospital de Referencia Nacional de Paraguay durante el año 2016. Este fue un estudio observacional descriptivo de corte transversal. Fueron incluidos todos los pacientes registrados como donantes voluntarios y de reposición que acudieron al hospital durante los meses de enero a diciembre del 2016. La población base estuvo conformado por 21.428 donantes, de los cuales 10.05% presentó pruebas serológicas reactivas. La mediana de edad fue de 32 años, el rango etario más frecuente fue entre 25 a 29 años, el sexo masculino tuvo una frecuencia de 66.89% en los donantes, y el 56.69% de los donantes contaba con seguro médico. El 0.75% fueron donantes voluntarios mientras que el marcador más prevalente fue para sífilis con 5.36%. En relación al Informe del Estado Global de la seguridad de la sangre y su disponibilidad publicado por la Organización Mundial de la Salud (OMS) en el año 2012, los resultados son coherentes con las seroprevalencias dadas por el mismo


The use of blood components has become very important for the clinical management of various pathologies, however, it is not exempt from complications, one of them being transfusion-transmitted infections (TTI). In the last decades, the risk of ITT has been reduced effectively thanks to the screening of serological markers in donors. The objective of this study was to determine the seroprevalence of markers for transfusion-transmitted infections in donors of a national reference hospital of Paraguay during 2016. This was a descriptive observational cross-sectional study with non-probabilistic convenience sampling. All patients registered as voluntary and replacement donors who attended the hospital during the months of January to December 2016 were included. The base population consisted of 21,428 donors, of which 10.05% presented reactive serological tests. The median age was 32 years, the most frequent age range was 25 to 29 years, 66.89% was men, 56.69% of donors had health insurance and 0.75% was voluntary donors. The most prevalent marker was for syphilis (5.36%). In relation to the Report of the Global State of blood safety and its availability published by the World Health Organization (WHO) in 2012, the results are consistent with the prevalence given by this report
