ABSTRACT

Abstract Introduction: Graft-versus-host disease (GVHD) is a serious complication in allogeneic transplantation. The first-line treatment is high doses of corticosteroids. In the absence of response to corticosteroids, several immunosuppressive drugs can be used, but they entail an elevated risk of severe infections. Added to this, there are patients who do not improve on any immunosuppressive treatment, with subsequent deteriorated quality of life and high mortality. Ruxolitinib has been shown to induce responses in refractory patients. In this study we have presented our real-life experience. Methods: A retrospective analysis was performed on patients with severe GVHD refractory to corticosteroids. Demographic, previous treatment, response and mortality data were collected. Results: Since 2014, seventeen patients with GVHD were treated with ruxolitinib due to refractoriness to corticosteroids and immunosuppressants and a few to extracorporeal photopheresis, 8 with acute GVHD (1 pulmonary, 4 cutaneous grade IV and 3 digestive grade IV) and 9 with chronic GHVD (5 cutaneous sclerodermiform, 2 pulmonary and 1 multisystemic). The overall response to ruxolitinib treatment for acute GVHD was 80%, 40% with partial response and 40% with complete remission. Global response in chronic GVHD was 79%. The GVHD mortality was only seen in acute disease and was 40%. Causes of mortality in those patients were severe viral pneumonia, post-transplantation hemophagocytic syndrome and meningeal GVHD refractory to ruxolitinib. Conclusions: In our series, the use of ruxolitinib as a rescue strategy in acute or chronic GVHD was satisfactory. Ruxolitinib treatment in patients with a very poor prognosis showed encouraging results. However, the GVHD mortality remains high in refractory patients, showing that better therapeutic strategies are needed.

ABSTRACT

Introducción: El cáncer pediátrico es un importante problema de salud pública y el más frecuente es la leucemia. En ocasiones, esta enfermedad puede generar depleción de las líneas celulares y es la transfusión de hemocomponentes un importante pilar de su tratamiento. Este procedimiento puede generar reacciones postransfusionales que pueden ser letales. Objetivo: Exponer las diferentes características clínicas y epidemiológicas de las reacciones postransfusionales en población pediátrica con leucemia. Métodos: Se realizó una búsqueda sistemática en las principales bases de datos de literatura médica. Se incluyeron 46 artículos. Resultados: La complicación más frecuente es la reacción febril no hemolítica. También es frecuente la sobrecarga de hierro. El factor de riesgo más importante para presentar esta sobrecarga es el número de transfusiones. Es necesario monitorizar la cantidad de hierro hepático. La reacción pulmonar aguda relacionada con la transfusión es una condición potencialmente mortal. Las infecciones pueden presentarse y pueden ser mortales dada la inmunosupresión de este grupo de pacientes. Otras reacciones inmunológicas pueden ser raras, pero deben ser tenidas en cuenta. Consideraciones finales: Las reacciones postransfusionales pueden ser más graves en los pacientes con leucemia. Se requiere realizar estudios con modelos epidemiológicos adecuados para identificar las reacciones postransfusionales más frecuentes en población pediátrica con esta enfermedad(AU)


Introduction: Pediatric cancer is a major public health problem and leukemia is the most common. Sometimes this disease can lead to depletion of cell lines and the transfusion of blood components is an important pillar of their treatment. This procedure can generate post-transfusion reactions that can be lethal. Objective: Show the different clinical and epidemiological characteristics of post-transfusion reactions in pediatric population with leukemia. Methods: A systematic search was carried out in the main databases of medical literature. 46 items were included. Results: The most common complication is the non-hemolytic febrile reaction. Iron overloading is also common. The most important risk factor for this overload is the number of transfusions. It is necessary to monitor the amount of iron in the liver. Acute transfusion-related pulmonary reaction is a life-threatening condition. Infections can occur and can be fatal given the immunosuppression of this group of patients. Other immune reactions may be rare, but they should be taken into account. Final considerations: Post-transfusion reactions may be more severe in patients with leukemia. Studies with appropriate epidemiological models are required to identify the most common post-transfusion reactions in the pediatric population with this disease(AU)

ABSTRACT

Allergic transfusion reaction (ATR) caused by plasma transfusion is one of the main adverse transfusion reactions, and severe allergic reactions may even endanger the patient's life. Currently, ATR is mainly prevented and controlled by drug prevention and symptomatic treatment, and there still lack of preventive measures such as in vitro experiments. It has been shown that mast cells and basophils are the main effector cells of allergic reactions, and histamine is one of the main mediators of IgE-mediated allergic reactions. Some experiments can be used to identify patients with allergies or plasma components containing allergens, such as detection of serum-specific IgE, IgA, anti-IgA antibody, tryptase and histamine, mast cell degranulation test, basophil activation test, and so on. The basophil activation test can also be used for functional matching of plasma in vitro. Research of in vitro experiment of ATR is good for directing the precise infusion of plasma, reducing waste of resources, and avoiding the risk of blood transfusion. As a pre-transfusion laboratory test for clinical use, in vitro experiment of functional matching provides a new way to prevent ATR.

ABSTRACT

Blood transfusion is a tool capable of saving lives. Patients undergoing blood transfusion usually present several alterations in the acid-base and electrolyte balance, aggravating the condition of critically ill patients. Some studies have demonstrated haematological alterations in certain species that received whole blood transfusions, however, few studies have evaluated acid base and electrolyte changes in dogs undergoing whole blood haemotherapy. The aim of this study was to analyze clinical, hematological, blood gas and electrolyte changes in anemic dogs after whole blood transfusion. Twenty nine dogs transfused due to anemia were enrolled in the study. Donors blood was collected in a transfusion bag containing citrate phosphate adenine dextrose and stored up to 24 h. Blood collections and evaluations were made before and 24 h after the transfusion. Data distribution normality was tested by the Shapiro Wilk Test. The means of the variables were compared by paired t-test. It was observed an increase in diastolic blood pressure and a reduction in heart rate (P < 0.05). There was a not significant increase in systolic blood pressure, temperature, and a reduction in respiratory rate per minute. Erythrocyte, haemoglobin and haematocrit averages were significantly increased after blood transfusion (P < 0.05). It was observed a reduction in the mean values of pH (P < 0.05), potassium (P > 0.05) and ionized calcium (P > 0.05) and an increase in the mean partial pressure of carbon dioxide (pCO2 ) (P < 0.001), bicarbonate (P > 0.05) and sodium (P < 0.05). The probable cause of anemia was monocytic ehrlichiosis (14/29), visceral leishmaniasis (1/29), babesiosis (1/29), co-infection of Ehrlichia canis and Leishmania infantum (2/29), co-infection of E. canis and Babesia vogeli (1/29). It was not possible to determine the etiology of the anemia in ten dogs. Heart rate significantly reduced after transfusion, probably because of the increase in hematocrit, hemoglobin and erythrocyte values. It may be justified by the displacement of extravascular fluid to the intravascular space. Mean values of systolic blood pressure were slightly elevated before transfusion and remained elevated afterwards, while diastolic and mean arterial pressure increased significantly after transfusion. These changes may be due to the morbid condition and may be influenced by many other factors. Haematocrit, haemoglobin and erythrocyte values increased significantly after transfusion, according to what was observed in other studies. The significant reduction in pH and increase in pCO2 reflects the compensatory mechanism for metabolic acidosis to increase ventilation, leading to pCO2 reduction and changes in pH. The reduction in pH due to the contact of the collected blood with conservative solutions is one of the main changes thar occurs during blood storage. It was described significantly lower pH in dogs' whole blood samples stored for more than 24 h in vacutainer plastic containing CPDA-1. We may assume there was no intense pH reduction in the present study because the bags were stored for up to 24 h. Although not statistically significant, the increase of pO2 mean reflects the improvement of tissue oxygen perfusion. It was observed a significant increase in sodium ions. The mean sodium ion concentration before transfusion was very close to the maximum reference value. Hyperkalaemia was not observed, nor was there significant reduction of potassium ions after transfusion. Several studies report hyperkalaemia and transfusion-associated cardiac arrests in humans, associated with infusion of large volumes of blood. Whole blood transfusion increased erythrogram values and did not negatively affect the electrolyte or acid-base status, representing a safe and useful tool in the intensive care of small animals.(AU)

ABSTRACT

ABSTRACT A 10-year-old Malay girl with underlying HbE/beta-thalassemia, on regular blood transfusion and deferoxamine iron chelation therapy, presented with two-month history of bilateral blurring of vision. On examination, her vision was 6/36 both eyes. Other optic nerve functions were normal. Anterior segment examination of both eyes was unremarkable. Fundus examination of both eyes revealed dull foveal reflex. Optical coherence tomography of both maculae showed increased central subfield thickness. Fundus fluorescence angiography showed patchy hypofluorescence over macular region for both eyes and late staining, indicating retinal pigment epithelium anomalies. A diagnosis of iron-chelation-therapy-related bilateral maculopathy was made. Patient was co-managed with pediatric hematology team to adjust the dose of deferoxamine, and was given three monthly appointments to monitor the progression of maculopathy at the ophthalmology clinic. However patient defaulted ophthalmology follow-up after the first visit.


RESUMO Uma menina malaia de 10 anos de idade com doença de base- B/beta-talassemia, em transfusão de sangue regular e terapia quelante de ferro deferoxamina, apresentou história de dois meses de visão turva bilateral. Ao exame, sua visão era de 6/36 em ambos os olhos. Outras funções do nervo óptico estavam normais. O exame do segmento anterior de ambos os olhos foi normal. Exame do fundo de ambos os olhos revelou reflexo foveal opaco. A tomografia de coerência óptica de ambas as máculas mostrou aumento da espessura do subcampo central. A angiografia de fluorescência do fundo mostrou hipofluorescência irregular sobre a região macular de ambos os olhos e coloração tardia, indicando anomalias de epitélio pigmentar da retina. Um diagnóstico de maculopatia bilateral relacionada à terapia quelante de ferro foi feito. A paciente foi avaliada em conjunto com a equipe de hematologia pediátrica para ajustar a dose de deferoxamina, e foram oferecidas três consultas mensais na clínica oftalmológica, para monitorar a progressão da maculopatia. No entanto, ela não compareceu para acompanhamento oftalmológico após a primeira visita.

ABSTRACT

Quando um indivíduo é exposto a antígenos eritrocitários não próprios, ocorre uma resposta imunológica, que leva à produção de anticorpos irregulares voltados contra esses antígenos. Esse processo é conhecido como aloimunização eritrocitária e acontece em decorrência de transfusões de sangue ou gestações incompatíveis. Na medicina transfusional a pesquisa de anticorpos irregulares é fundamental, pois a falha na detecção de um aloanticorpo pode provocar reações transfusionais, aloimunizações, anemias hemolíticas autoimunes e doença hemolítica perinatal. Este estudo tem por objetivo analisar a frequência de anticorpos irregulares de pacientes atendidos no Hemocentro Regional de Francisco Beltrão, Paraná, no ano de 2017. Os dados foram coletados a partir da revisão de registros em arquivos do Laboratório de Imunohematologia do Hemonúcleo. Foram avaliados dados de 49 protocolos de pacientes que apresentaram dificuldades transfusionais no ano de 2017. Dentre os pesquisados, 37 pacientes (75,5%) apresentaram anticorpos irregulares. Dentre os anticorpos anti-eritrocitários observados neste estudo, evidenciou-se a presença de doze pacientes com anti-D (27,2%), seis pacientes com anti-K (13,6%), quatro pacientes com anti-C (9,0%) e em seis pacientes (13,6%) foi observada a presença de autoanticorpos. Este estudo indica que, nos pacientes transfundidos, os anticorpos mais frequentes foram os aloanticorpos Anti-D do Sistema Rh, provavelmente devido ao seu alto grau de imunogenicidade. A prevalência desses anticorpos é semelhante a vários estudos encontrados na literatura.


When an individual is exposed to not-self red blood cell antigens, an immune response occurs, which leads to the production of irregular antibodies directed against these antigens. This process is known as erythrocyte alloimmunization and occurs as a result of blood transfusions or incompatible pregnancies. In transfusion medicine, the search for irregular antibodies is essential, since failure to detect an alloantibody can cause transfusion reactions, alloimmunizations, autoimmune hemolytic anemias, and perinatal hemolytic disease. This study aims at analyzing the frequency of irregular antibodies of patients seen at the Regional Blood Center of Francisco Beltrão, Paraná, in 2017. The data were collected from the review of records in files of the Immunohematology Laboratory of Hemonúcleo. Data from 49 protocols of patients who had transfusion difficulties in 2017 were evaluated. Among those surveyed, 37 patients (75.5%) had irregular antibodies. Among the anti-erythrocyte antibodies observed in this study, the presence of twelve patients with anti-D (27.2%), six patients with anti-K (13.6%), four patients with anti-C (9.0 %), and in six patients (13.6%) with the presence of autoantibodies were observed. This study indicates that, in transfused patients, the most frequent antibodies were the Rh System Anti-D alloantibodies, probably due to their high degree of immunogenicity. The prevalence of these antibodies is similar to several studies found in the literature.

ABSTRACT

RESUMO: Estudo analítico, transversal, retrospectivo. Objetivos: Verificar a relação entre reações transfusionais imediatas, características demográficas e clínicas dos pacientes e características das hemotransfusões em um hemocentro universitário. Metodologia: O estudo foi realizado com dados de transfusões realizadas em 2016 no hemocentro da Universidade Federal de São Paulo. Foram coletados dados demográficos dos pacientes, características das hemotransfusões e ocorrência de reações transfusionais imediatas. Possíveis associações foram avaliadas usando os Testes de Fisher, Mann-Whitney, Qui-quadrado e t de Student. Associações com valores de p<0,05 foram consideradas significativas. Resultados: Foram analisados dados de 320 fichas de pacientes, totalizando 938 transfusões. Dos produtos sanguíneos transfundidos, 90,3% eram concentrados de hemácias, administrados por auxiliares de enfermagem em 43,8% das situações. As reações transfusionais ocorreram em 4,3% das situações (n=40). O sinal de reações mais frequente foi a febre (47,5%), seguido de prurido (22,5%). As reações foram mais prevalentes em pacientes com maior idade média (p= 0,0037), que receberam duas transfusões sanguíneas em comparação a uma (p<0,0001), consequentemente mais bolsas de transfusões (p=0,0002), maior volume total transfundido (p<0,0001) e maior tempo de administração (p=0,0017). Pacientes com anemia aplásica, leucemia mieloide aguda e neoplasias de órgãos sólidos tiveram reações transfusionais imediatas mais frequentemente do que pacientes com outros diagnósticos (p≤0,05). Conclusões: A ocorrência de reações transfusionais imediatas teve relação com a idade, diagnóstico médico, número de hemotransfusões, número de bolsas transfundidas, volume total transfundido e tempo de transfusão. O conhecimento desses fatores pode subsidiar treinamentos específicos voltados para a vigilância quanto às reações transfusionais imediatas. (AU)


ABSTRACT An analytical, cross-sectional, retrospective study. Objectives: To investigate the relationship among immediate transfusion reactions, patient's demographic and clinical characteristics, and transfusion-related characteristics in a university blood center. Methodology: The study was performed with data regarding blood transfusions of the blood center at Universidade Federal de São Paulo in 2016. Patient's demographic and clinical characteristics and the characteristics of the immediate trans-fusion reactions were collected. Possible associations were evaluated using Fisher's exact test, Mann-Whitney, Chi-square, and Student's t-test. Associations with p≤0.05 were considered statistically significant. Results: Data from 320 patient records were analyzed, totaling 938 blood transfusions. Of the blood products transfused, 90.3% were packed red blood cells administered by nursing assistants in 43.8% of the situations. Immediate transfusion reactions occurred in 4.3% of the situations (n=40). The most common transfusion reaction was fever (47.5%), followed by pruritus (22.5%). The transfusion reactions were more frequent in older patients (p=0.0037) who received two blood transfusions compared to one (p<0.0001), consequently more transfusion bags (p=0.0002), greater total transfused volume (p <0.0001), and longer length of administration (p=0.0017). Patients with aplastic anemia, acute myeloid leukemia, and solid organ neoplasms had immediate transfusion reactions more frequently than patients with other diagnoses (p <0.05). Conclusion: The occurrence of immediate transfusion reactions was related to age, medical diagnosis, number of blood transfusions, number of transfused bags, total transfused volume, and length of administration. Knowledge of these factors may support specific training for immediate transfusion reactions surveillance.

ABSTRACT

ABSTRACT Background: Blood transfusion is a life-saving procedure, but may cause adverse transfusion reactions (TRs). The reporting of TRs is often missed due to various reasons. The aim of this study was to determine the incidence of unreported acute TRs through active surveillance and to compare it with the incidence of passively reported TRs. Methods: This prospective observational study was done over a period of four months at a tertiary care hospital. A total of 500 consecutive transfusion episodes (TEs) in patients who had received blood component transfusions in the intensive care units were included in the study. Comprehensive data were collected from the blood bank records, patient records and through interviews with the attending clinical staff. The TEs were defined as all blood components issued to a single patient in 24 h. Results: The overall incidence of TRs was 1.8 % (9 cases), with 0.4 % (2 cases) being reported passively, while 1.4 % (7 cases) were identified during active surveillance. The transfusion-associated cardiac overload (TACO) had the highest incidence of 1.2 % (6 cases) in active surveillance. A single case of acute hemolytic transfusion reaction was also observed during active surveillance. The passively reported TRs were one allergic reaction and one febrile non-hemolytic transfusion reaction. Conclusion: Active surveillance of TRs provided an insight into the true incidence of TRs, which is higher when compared with the passively reported TRs. The TACO was found to have the highest incidence and not a single case was reported. There is a need to improve awareness regarding TR reporting.

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

ABSTRACT

OBJECTIVE@#To investigate the related factors of adverse reactions of blood transfusion, and clinical precautions so as to reduce the adverse reactions.@*METHODS@#Data of 2108 patients with allogeneic transfusion in our hospital from January 2017 to June 2017 collected and analyzed.@*RESULTS@#These patients received 15 244 time of blood transfusion, and 213 time of adverse reactions occurred in 178 patients in totality, the incidence is 1.4%, and there was no significant difference between the male (1.31%) and female (1.53%). The main type of transfusion reaction were allergy (73.23%), FNHTR (11.74%) and TACO (10.80%). Among all kinds of blood components, the incidence of adverse reactions of apheresis platelet transfusion was the highest (4.31%), significantly higher than that of cryoprecipitate and other blood components. The incidence rate of adverse reactions of blood transfusion in the hematopathy patients was 2.56%, significantly higher than that of immune diseases (1.48%), cancer diseases (1.28%) and other diseases (1.08%), (P<0.01). The rate of transfusion history of apheresis platelets was 42.67% (the incidence of adverse reactions was 4.31%), significantly higher than other groups (P<0.01); the rate of transfusion history of cryoprecipitate was 4.11% (the incidence of adverse reaction was 0.45%), significantly lower than other groups (P<0.05). Among the disease types, the rate of transfusion history in the hematopathy patients was 48.79% (the incidence of adverse reaction was 2.56%), significantly higher than that of other groups (P<0.01). The incidence of drug allergy in patients with the adverse reactions to blood transfusion was 11.25%, significantly higher than that of patients without adverse reactions (4.71%) (P<0.01).@*CONCLUSION@#The main risk factors of adverse reactions of blood transfusion are as follows: blood varieties, disease type, transfusion history and drug allergy history. For the patients with transfusion, multiple factors should be controlled, so as to reduce the adverse reactions.

ABSTRACT

ABSTRACT The correct identification of erythrocyte antibodies is fundamental for the searching for compatible blood and haemolytic transfusion reactions prevention. Antibodies against antigens of high prevalence are difficult to identify because of the rarity of their occurrence and unavailability of negative red cells for confirmation. We report a case of 46-years-old woman, diagnosed with hemoglobinopathy, and who had symptomatic fall in hemoglobin levels (5.3g/dL) after blood transfusion suggestive of transfusion reaction. The patient's blood type was O RhD-positive. Irregular antibody screening was positive and demonstrated a panreaction against all erythrocytes tested, but this result was not reactive with dithiothreitol. Using negative red cells for antigens of high prevalence of our inventory we could identify in the serum of the same erythrocytes an anti-Holley antibody associated with anti-E. Molecular analysis confirmed that the patient was negative for E and Holley antigens. The crossmath with compatible units confirmed the results. Holley is a high prevalence antigen of the Dombrock blood system whose negative phenotype is extremely rare in all populations and is associated with hemolytic transfusion reactions. This is an antibody that is difficult to identify because laboratories need to have experience in solving complex cases, and have available a large stock of rare sera and erythrocytes, as well other tools such as enzymes, thiol reagents and molecular tests. The correct identification of a rare antibody is initial and mandatory for searching of compatible donors, and to guarantee a satisfactory transfusional support.


RESUMO A correta identificação dos anticorpos eritrocitários é fundamental na busca de sangue compatível e na prevenção das reações transfusionais hemolíticas. Anticorpos contra antígenos de alta prevalência são de difícil identificação, devido à raridade de sua ocorrência e à indisponibilidade de hemácias negativas para sua confirmação. Apresentamos aqui o caso de uma paciente do sexo feminino, 46 anos, com diagnóstico de hemoglobinopatia, que apresentou queda sintomática dos níveis de hemoglobina (5,3g/dL) após transfusão sanguínea, sugestiva de reação transfusional. O tipo sanguíneo da paciente era O RhD-positivo. A pesquisa de anticorpos irregulares foi positiva, demonstrando panreação contra todos os eritrócitos testados, mas não reativo ao ditiotreitol. Utilizando hemácias selecionadas negativas para antígenos de alta prevalência do nosso inventário, foi possível identificar no soro da mesma um anticorpo anti-Holley associado a um anti-E. A análise molecular confirmou que a paciente era negativa para os antígenos E e Holley, e as provas de compatibilidade com unidades fenotipadas confirmaram os resultados. Holley é um antígeno de alta prevalência do sistema sanguíneo Dombrock, cujo fenótipo negativo é extremamente raro em todas as populações e está associado a reações transfusionais hemolíticas. Trata-se de anticorpo de difícil identificação, pois os laboratórios precisam ter experiência na resolução de casos complexos, grande estoque de soros e eritrócitos raros, além de outras ferramentas, como enzimas, reagentes tiol e testes moleculares. A identificação correta de um anticorpo raro é inicial e obrigatória para a busca de doadores compatíveis, garantindo um suporte transfusional satisfatório.

ABSTRACT

ABSTRACT Background: Blood transfusion-transmitted infections in individuals suffering from beta-thalassemia have been reported in Pakistan, but the information on their sociodemographic and clinical determinants is lacking. This study aims to describe the prevalence, as well as the factors, contributing in blood transfusion-transmitted infections. Method: Between December 2011 and December 2013, in a non-probable sampling, 350 thalassemia patients were recruited in Lahore, Multan, Karachi and Peshawar, Pakistan. Subjects were screened for transfusion-transmitted infections. Results: A seropositive rate of 36.5% was observed; males (94, 73.4%) and females (34, 26.6%). Among several risk factors associated with transfusion-transmitted infections, province (p = 0.001), gender (p = 0.003), age (p < 0.03), education (p < 0.00), degree of consanguinity (p = 0.05), age at fetal blood test (p = 0.005), fetal hemoglobin levels (p = 0.005), death due to thalassemia (p = 0.001) and iron-related complications (p = 0.04) showed significant correlation. Participants with an age >10 years were significantly more prone to seropositivity than those aged ≤10 years. Moreover, the ferritin level was also significantly higher in those aged >10 years than in those ≤10 years. It was observed that males had a higher seroprevalence rate (94, 73.4%) than females (34, 26.6%). The most prevalent transfusion-transmitted infections was the hepatitis C virus, with 115 cases (89.8%). Conclusion: A high prevalence rate of HCV in subjects with transfusion-dependent thalassemia is linked with insufficient facilities, poor management and compromised socioeconomic status. Therefore, more multicenter studies covering cities from different regions of the country are needed in order to develop preventive measurements at the regional and national level.

ABSTRACT

Abstract Bartonellosis are diseases caused by any kind of Bartonella species. The infection manifests as asymptomatic bacteremia to potentially fatal disorders. Many species are pathogenic to humans, but three are responsible for most clinical symptoms: Bartonella bacilliformis, Bartonella quintana, and Bartonella henselae. Peruvian wart, caused by B. bacilliformis, may be indistinguishable from bacillary angiomatosis caused by the other two species. Other cutaneous manifestations include maculo-papular rash in trench fever, papules or nodules in cat scratch disease, and vasculitis (often associated with endocarditis). In addition, febrile morbilliform rash, purpura, urticaria, erythema nodosum, erythema multiforme, erythema marginatus, granuloma annularis, leukocytoclastic vasculitis, granulomatous reactions, and angioproliferative reactions may occur. Considering the broad spectrum of infection and the potential complications associated with Bartonella spp., the infection should be considered by physicians more frequently among the differential diagnoses of idiopathic conditions. Health professionals and researchers often neglected this diseases.

ABSTRACT

Transfusion-associated circulatory overload (TACO) is recently becoming more important than transfusion-related acute lung injury (TRALI) in terms of the number of patients with definite diagnosis as well as its prognosis. In order to diagnose TACO, it is helpful to recognize early the symptoms suspicious of transfusion reaction through electronic medical record system and computer network, and this will be of help for obtaining samples for brain natriuretic peptide (BNP) measurement before and after the onset of transfusion reaction. We report a case in which a transfusion reaction was diagnosed as TACO. A 62-year-old woman was admitted to the emergency room due to bleeding tendency. Two fresh frozen plasma units and one unit of leukocyte-reduced red blood cells were transfused. Blood pressure increased during transfusion, and the chest X-ray showed findings suggestive of newly developed pulmonary edema. N-terminal prohormone of BNP (NT-proBNP) test was carried out using the specimens in refrigerated storage. Compared with the NT-proBNP level measured 12 hours before the transfusion, that measured 6 hours after the transfusion was markedly increased (>48 fold of pre-transfusion level). As a result, this case was diagnosed with TACO.

ABSTRACT

Transfusion-related acute lung injury (TRALI) is defined as a new episode of acute lung injury that occurs during or within 6 hours of a completed transfusion, which is one of the leading causes of transfusion-related morbidity and mortality. We present a case of TRALI in a 29-year-old parturient with myelodysplastic syndrome scheduled for cesarean section. The parturient developed hypoxemia and dyspnea after preoperative transfusion of platelets following apheresis to eliminate a unit of leucocyte in order to correct thrombocytopenia. She underwent emergent caesarean section for fetal distress. After surgery, the chest radiograph showed diffuse haziness of both lung fields. Direct and indirect antiglobulin tests were negative, and hemolytic transfusion reaction was ruled out. Pro-BNP 347.3 pg/ml also excluded transfusion-associated circulatory overload. The parturient completely recovered after oxygen support for 2 days. It is important to recognize TRALI as soon as possible to minimize perioperative morbidity and mortality.

ABSTRACT

OBJECTIVE@#To explore the feasibility of RhCcEe blood group antigen mixed visual field identification in patients with regular blood transfusion, to follow up and evaluate the efficacy of matched transfusion and its clinical significance.@*METHODS@#RhCcEe genotyping for 142 patients with regular transfusion in our hospital was carried out by PCR-SSP method. According to the results of genotyping, 48 patients voluntarily selected the continuous transfusion of RhCcEe matched red blood cells, 46 patients received random blood transfusion (RhCcEe mismatched transfusion), 42 patients received partial RhCcEe matched transfusion (unable to provide fully matched RhCcEe donors each time), and 6 patients' blood transfusion data were lost. After 3-6 months of the RhCcEe matched transfusion, all patients were tested by RhCcEe microcolumn gel card and compared with the results before RhCcEe matched transfusion. The positive rates of alloantibodies, DAT and the percentage of red blood cell invalid transfusion were followed up and evaluated for the above-mentsioned 3 types of regular transfusion patients in the past 5 years.@*RESULTS@#Out of the 48 patients who underwent conti-nuous RhCcEe matched transfusion, only 1 case showed stratification, the remaining 47 cases had clear gel card results without stratification, suggesting that PCR-SSP genotyping was feasible. In addition, another 42 patients who could not receive RhCcEe matched transfusion each time and 46 patients with random blood transfusion were found to have a mixed vision phenomenon again. but the results was still difficult to confirm the results. For the transfusion results in the past 5 years, follow-up analysis showed that there were 1 case alloantibody (anti-Jka) (1/48) , 1 case of DAT positive (1/48) and 2 cases of invalid transfusion (2/48) in the RhCcEe matched transfusion group; 7 cases of alloantibodies (3 anti-E, 1 anti-E+anti-c, 1 anti-C, 1 anti-M, 1 anti-Fya) (7/46), 6 case of DAT positive (6/46) and 9 case of invalid transfusion (9/46) in the random transfusion group; 6 cases of alloantibodies (1 anti-E, 1 anti-E+autoantibody, 1 anti-C, 1 anti-c, 1 anti-M and 1 other antibody) (6/42) and 7 case of DAT positive (7/42) and 8 case of invalid transfusion (8/42) in the partial RhCcEe matched transfusion group. The statistical analysis showed that the positive rate of alloantibodies and the invalid infusion rate of RBC in each group were significant differences between RhCcEe matched transfusion group and the random transfusion group as well as betwen Rhce fe matched transfusion group and the partial matched transfusion group(P<0.05), but there was no statistical difference between the random transfusion group and the partial matched transfusion group(P>0.05).@*CONCLUSION@#PCR-SSP genotyping technique can be used to detect RhCcEe mixed vision in patients with regular blood transfusion. Continuous RhCcEe matched transfusion can effectively prevent the occurrence of alloimmunization, and improve the clinical transfusion efficacy and safety of the patients with regular blood transfusion, which has very important clinical significance.
