PERFIL CLÍNICO DE NIÑOS SOMETIDOS A TRASPLANTE DE CÉLULAS MADRE HEMATOPOYÉTICAS

Objective: to identify the clinical profile of children in the hematopoietic stem cell post-transplant period.Method: quantitative, cross-sectional, retrospective study, performed in a transplantation service of the South of Brazil, with data from the medical records of children less than 12 years of age, who had undergone transplantation. Measures of central tendency, dispersion and frequency were used for the analysis and the chi-squared and Fisher’s tests to associate variables.Results: the mean age was 6.2 years, males, with 92 (66.7%), the diagnosis of Fanconi anemia, with 42 (30.4%), and unrelated allogeneic transplantation, with 71 (51.4%), were predominant. Hospital discharge occurred within 30 days after transplantation for 85 (61.6%) patients and 48 (34.8%) were readmitted. Catheter failures occurred in 11 children (8.0%) and the main outpatient clinical intercurrences were pain, cough, runny nose and fever. Viral infection was associated with the unrelated transplant and graft-versus-host disease.Conclusion: the profile identified corroborates the care planning for this population, contributing to the nursing practice.Objetivo: identificar o perfil clínico de crianças em pós-transplante de células-tronco hematopoiéticas.Método: pesquisa quantitativa, transversal, retrospectiva, em serviço transplantador do Sul/Brasil, com dados de prontuários de crianças com 12 anos incompletos, submetidas a transplante. Para análise utilizaram-se medidas de tendência central, dispersão, frequências e testes do qui-quadrado e Fisher para associar variáveis.Resultados: a média de idade foi de 6,2 anos, predomínio do sexo masculino 92 (66,7%), diagnóstico Anemia de Fanconi 42 (30,4%) e transplante alogênico não aparentado 71 (51,4%). A alta hospitalar aconteceu em até 30 dias pós-transplante para 85 (61,6%) e 48 (34,8%) foram reinternadas. As perdas do cateter acometeram 11 crianças (8%) e as principais intercorrências clínicas ambulatoriais foram dor, tosse, coriza e febre. Infecção viral esteve relacionada ao transplante não aparentado e doença do enxerto contra hospedeiro.Conclusão: o perfil identificado corrobora o planejamento de cuidados a esta população, contribuindo com a prática de enfermagem.Objetivo: identificar el perfil clínico de niños tras realización de trasplante de células madre hematopoyéticas.Método: investigación cuantitativa, trasversal, retrospectiva, en servicio trasplantador de Sur/Brasil, con datos de prontuarios de niños con 12 años sin cumplir, sometidos a trasplante. Para análisis, se utilizaron medidas de tendencia central, dispersión, frecuencias y prueba chi cuadrada y Fisher a fin de asociar variables.Resultados: el promedio de edad fue de 6,2 años, predominio del sexo masculino, 92 (66,7%), diagnóstico Anemia de Fanconi 42 (30,4%) y trasplante alógeno sin parentesco 71 (51,4%). El alta hospitalario ocurrió en hasta 30 días tras el trasplante para 85 (61,6%) y 48 (34,8%) se reingresaron. Las pérdidas del catéter atingieron 11 niños (8%) y las principales complicaciones clínicas ambulatorias fueron dolor, tos, secreción nasal y fiebre. Infección viral fue asociada al trasplante sin parentesco y enfermedad del injerto contra huésped.Conclusión: el perfil identificado corrobora el planeamiento de cuidados a esa población, contribuyendo con la práctica de enfermería

The Changing Epidemiology of Bloodstream Infections and Resistance in Hematopoietic Stem Cell Transplantation Recipients

Objective: Patients receiving hematopoietic stem cell transplantation (HSCT) are exposed to highly immunosuppressive conditions and bloodstream infections (BSIs) are one of the most common major complications within this period. Our aim, in this study, was to evaluate the epidemiology of BSIs in these patients retrospectively. Materials and Methods: The epidemiological properties of 312 patients with HSCT were retrospectively evaluated. Results: A total of 312 patients, followed between 2000 and 2011, who underwent autologous (62%) and allogeneic (38%) HSCT were included in the study. The most common underlying malignancies were multiple myeloma (28%) and Hodgkin lymphoma (21.5%). A total of 142 (45%) patients developed at least 1 episode of BSI and 193 separate pathogens were isolated from the blood cultures. There was a trend of increase in the numbers of BSIs in 2005-2008 and a relative increase in the proportion of gram-positive infections in recent years (2009-2011), and central venous catheter-related BSI was found to be most common source. Coagulase-negative staphylococci (49.2%) and Acinetobacter baumannii (8.8%) were the most common pathogens. Extended-spectrum beta-lactamase-producing strains were 23% and 22% among Escherichia coli and Klebsiella spp. isolates, respectively. Quinolone resistance was detected in 10% of Enterobacteriaceae. Resistance to carbapenems was not detected in Enterobacteriaceae, while it was seen at 11.1% and 23.5% in Pseudomonas and Acinetobacter strains, respectively. Conclusion: A shift was detected from gram-negative bacteria to gram-positive in the etiology over the years and central lines were the most common sources of BSIs
