RESUMO

Multiple myeloma (MM) associated with Chagas disease is rarely described. This disease and its therapy suppress T cell and macrophage functions and increase regulatory T cell function, allowing the increase of parasitemia and the risk of Chagas Disease Reactivation (CDR). We aimed to analyze the role of conventional (cPCR) and quantitative Polymerase Chain Reaction (qPCR) for prospective monitoring of T. cruzi parasitemia, searching for markers of preemptive antiparasitic therapy in MM patients with Chagas disease. Moreover, we investigated the incidence and management of hematological diseases and CDR both inside and outside the transplant setting in the MEDLINE database. We found 293 studies and included 31 of them. Around 1.9-2.0% of patients with Chagas disease were reported in patients undergoing Stem Cell Transplantation. One case of CDR was described in eight cases of MM and Chagas disease. We monitored nine MM and Chagas disease patients, seven under Autologous Stem Cell Transplantation (ASCT), during 44.56±32.10 months (mean±SD) using parasitological methods, cPCR, and qPCR. From these patients, three had parasitemia. In the first, up to 256 par Eq/mL were detected, starting from 28 months after ASCT. The second patient dropped out and died soon after the detection of 161.0 par Eq/mL. The third patient had a positive blood culture. Benznidazole induced fast negativity in two cases; followed by notably lower levels in one of them. Increased T. cruzi parasitemia was related to the severity of the underlying disease. We recommend parasitemia monitoring by qPCR for early introduction of preemptive antiparasitic therapy to avoid CDR.

RESUMO

We described 235 bloodstream infection (BSI) episodes in 146 hematopoietic stem cell transplantation (HSCT) outpatients and evaluated risk factors for hospitalization and death. Records of outpatients presenting with positive blood cultures over a 5-year period (January 2005 to December 2008) were reviewed. Variables with p< 0.1 in bivariate analysis were used in a regression logistic model. A total of 266 agents were identified, being 175 (66.7%) gram-negative, 80 (30.3%) gram-positive bacteria and 9 (3.4%) fungi. The most common underlying disease was acute leukemia 40 (27.4%), followed by lymphoma non-Hodgkin 26 (18%) and 87 patients (59.6%) were submitted to allogeneic hematopoietic stem cell transplant (HSCT). BSI episodes were more frequent during the first 100 days after transplantation (183 or 77.8%), and ninety-one (38.7%) episodes of BSI occurred up to the first 30 days. Hospitalization occurred in 26% of the episodes and death in 10% of cases. Only autologous HSCT was protector for hospitalization. Although, central venous catheter (CVC) withdrawal and the Multinational Association of Supportive Care in Cancer (MASCC) score up to 21 points were protector factors for death in the bivariate analysis, only MASCC remained as protector.

RESUMO

INTRODUCTION/OBJECTIVES: Acute myeloid leukemia (AML) accounts for 90% of all cases of acute leukemia in adults. In Brazil, the mortality from myeloid leukemia is 1.74/100 000 men and 1.37/100 000 women. Our aim was to review and update guidelines of the Brazilian Society of Bone Marrow Transplantation on indications of hematopoietic stem cell transplantation (HSCT) for the treatment AML. CONCLUSIONS: (i) Allo-HSCT is recommended for high-risk AML (IA); (ii) allo-HSCT is recommended for AML of intermediate risk (IA); (iii) allo-HSCT is recommended for AML relapsed/refractory (C4); (iv) auto-HSCT is recommended for AML after 1 consolidation (C4); (v) auto-HSCT is recommended for AML in CR1 (higher than QT in the Brazilian experience) (C4); (vi) auto-HSCT is accepted for AML M3 in second molecular complete remission (2B); (vii) peripheral blood instead of Bone Marrow HSC for advanced disease (2A); (viii) recommended conditioning protocols: Bu-Cy/Bu-Mel, Bu-Flu, TBI-Cy. In umbilical cord HSCT, consider ATG-based protocols (2A); (ix) allogeneic HSCT for the treatment of AML can be used in patients between 60 and 80 yr with good performance status and the absence of significant comorbidities (C4).

RESUMO

OBJECTIVES: We conducted a retrospective study on the impact of the empiric use of linezolid on mortality in vancomycin-resistant Enterococcus spp (VRE)-colonized hematology and hematopoietic stem cell transplantation (HSCT) patients. METHODS: VRE-colonized inpatients for whom complete data were available (n=100) were divided into two groups: those who received empiric linezolid in the course of fever refractory to broad-spectrum antibiotics, replacing the glycopeptide utilized for the previous 48 h, and those who did not (control group). All patients were followed until hospital discharge or death. The impact of linezolid and risk factors for all-cause mortality were evaluated; variables with p<0.10 were analyzed in a multivariate model. A Kaplan-Meier survival analysis was done to compare survival among febrile patients colonized by VRE who received empiric linezolid with patients who did not receive linezolid. RESULTS: Patients empirically prescribed linezolid were generally younger (median age 33 vs. 44 years; p=0.008) and more likely to be recipients of an allogeneic HSCT (24 (68.6%) vs. 24 (36.9%); p=0.009) than patients who did not receive the drug. Fourteen (21.5%) VRE bloodstream infections were diagnosed, all in patients who did not receive empiric linezolid (p=0.002). In-hospital mortality was comparable in empiric linezolid and non-linezolid users (19 (54.3%) vs. 27 (41.5%), respectively; p=0.293). The Kaplan-Meier survival analysis showed no significant difference in survival comparing the group that received linezolid to the group that did not (p=0.72). Graft-versus-host disease (GVHD; odds ratio (OR) 5.90, 95% confidence interval (CI) 1.46-23.79; p=0.012) and persistence of neutropenia (OR 6.93, 95% CI 1.72-27.94; p=0.0065) were independent predictors of all-cause in-hospital death in HSCT patients, and persistence of neutropenia in non-HSCT patients (OR 8.12, 95% CI 1.22-53.8; p=0.030). CONCLUSIONS: The empiric use of linezolid in VRE-colonized hematology patients had no impact on mortality, which appeared rather to be associated with the persistence of neutropenia in general and GVHD in the HSCT group.

RESUMO

INTRODUCTION: Autologous hematopoietic stem cell transplantation is a conduct used to treat some hematologic diseases and to consolidate the treatment of others. In the field of nursing, the few published scientific studies on nursing care and early hospital discharge of transplant patients are deficient. Knowledge about the diseases treated using hematopoietic stem cell transplantation, providing guidance to patients and caregivers and patient monitoring are important nursing activities in this process. Guidance may contribute to long-term goals through patients' short-term needs. AIM: To analyze the results of early hospital discharge on the treatment of patients submitted to autologous transplantation and the influence of nursing care on this conduct. METHODS: A retrospective, quantitative, descriptive and transversal study was conducted. The hospital records of 112 consecutive patients submitted to autologous transplantation in the period from January to December 2009 were revisited. Of these, 12 patients, who remained in hospital for more than ten days after transplantation, were excluded from the study. RESULTS: The medical records of 100 patients with a median age of 48.5 years (19-69 years) were analyzed. All patients were mobilized and hematopoietic stem cells were collected by leukapheresis. The most common conditioning regimes were BU12Mel100 and BEAM 400. Toxicity during conditioning was easily managed in the outpatient clinic. Gastrointestinal toxicity, mostly Grades I and II, was seen in 69% of the patients, 62% of patients had diarrhea, 61% of the patients had nausea and vomiting and 58% had Grade I and II mucositis. Ten patients required hospitalization due to the conditioning regimen. Febrile neutropenia was seen in 58% of patients. Two patients died before Day +60 due to infections, one with aplasia. The median times to granulocyte and platelet engraftment were 12 days and 15 days, respectively, with median red blood cell and platelet transfusions until discharge of three and four units, respectively. Twenty-three patients required rehospitalization before being discharged from the outpatient clinic. CONCLUSION: The median time to granulocyte engraftment was 12 days and during the aplasia phase few patients were hospitalized or suffered infections. The toxicity of the conditioning was the leading cause of rehospitalization. The nursing staff participated by providing guidance to patients and during the mobilization, transplant and outpatient follow-up phases, thus helping to successfully manage toxicity.

RESUMO

We describe the rate of incidence of Clostridium difficile-associated diarrhea (CDAD) in hematologic and patients undergone stem cell transplant (HSCT) at HC-FMUSP, from January 2007 to June 2011, using two denominators 1,000 patient and 1,000 days of neutropenia and the risk factors associated with the severe form of the disease and death. The ELISA method (Ridascreen-Biopharm, Germany) for the detections of toxins A/B was used to identify C. difficile. A multivariate analysis was performed to evaluate potential factors associated with severe CDAD and death within 14 days after the diagnosis of CDAD, using multiple logistic regression. Sixty-six episodes were identified in 64 patients among 439 patients with diarrhea during the study period. CDA rate of incidence varied from 0.78 to 5.45 per 1,000 days of neutropenia and from 0.65 to 5.45 per 1,000 patient-days. The most common underlying disease was acute myeloid leukemia 30/64 (44%), 32/64 (46%) patients were neutropenic, 31/64 (45%) undergone allogeneic HSCT, 61/64 (88%) had previously used antibiotics and 9/64 (13%) have severe CDAD. Most of the patients (89%) received treatment with oral metronidazole and 19/64 (26%) died. The independent risk factors associated with death were the severe form of CDAD, and use of linezolid.

RESUMO

AIM: The objective was to describe an outbreak of bloodstream infections by Burkholderia cepacia complex (Bcc) in bone marrow transplant and hematology outpatients. METHODS: On February 15, 2008 a Bcc outbreak was suspected. 24 cases were identified. Demographic and clinical data were evaluated. Environment and healthcare workers' (HCW) hands were cultured. Species were determined and typed. Reinforcement of hand hygiene, central venous catheter (CVC) care, infusion therapy, and maintenance of laminar flow cabinet were undertaken. 16 different HCWs had cared for the CVCs. Multi-dose heparin and saline were prepared on counter common to both units. FINDINGS: 14 patients had B. multivorans (one patient had also B. cenopacia), six non-multivorans Bcc and one did not belong to Bcc. Clone A B. multivorans occurred in 12 patients (from Hematology); in 10 their CVC had been used on February 11/12. Environmental and HCW cultures were negative. All patients were treated with meropenem, and ceftazidime lock-therapy. Eight patients (30%) were hospitalized. No deaths occurred. After control measures (multidose vial for single patient; CVC lock with ceftazidime; cleaning of laminar flow cabinet; hand hygiene improvement; use of cabinet to store prepared medication), no new cases occurred. CONCLUSIONS: This polyclonal outbreak may be explained by a common source containing multiple species of Bcc, maybe the laminar flow cabinet common to both units. There may have been contamination by B. multivorans (clone A) of multi-dose vials.

O objetivo foi descrever um surto de infecções da corrente sanguínea por complexo B. cepacia (Bcc) nos ambulatórios de hematologia e transplante de medula óssea. Métodos: Em 15/02/2008, um surto de Bcc foi suspeitado. 24 casos foram identificados. Os dados demográficos e clínicos foram avaliados. Mãos de profissionais da saúde e ambiente foram cultivadas. Espécies foram determinadas e tipadas. Reforço da higiene das mãos, cuidados com cateteres, terapia de infusão e manutenção da câmara de fluxo laminar foram realizadas. 16 profissionais de saúde (PS) diferentes manipularam os cateteres. Heparina multidoses e soro eram preparadas em um balcão comum a ambas as unidades. Resultados: 14 pacientes tiveram B. multivorans (um paciente teve também B. cenopacia), 6 Bcc não-multivorans e um teve um agente não pertencente a Bcc. Clone A de B. multivorans ocorreu em 12 pacientes (da Hematologia), em 10 o cateter havia sido utilizado nos dias 11 ou 12 de fevereiro. Culturas ambientais e de PS foram negativos. Todos os pacientes foram tratados com meropenem e selo de ceftazidima. Oito pacientes (30%) foram hospitalizados. Não ocorreram mortes. Após as medidas de controle, nenhum novo caso ocorreu. Conclusões: Este surto policlonal pode ser explicado por uma fonte comum contendo várias espécies de Bcc, talvez a câmara de fluxo laminar comum a ambas as unidades. Pode ter havido contaminação por B. multivorans (clone A) de frascos multi-dose.

RESUMO

OBJECTIVES: Oral mucositis is a complication frequently associated with hematopoietic stem cell transplantation, decreasing a patient's quality of life and increasing the occurrence of opportunistic infections. The purpose of this study was to determine the incidence and severity of oral mucositis and to assess the correlation of this disease with the oral health of an individual at the time of hematopoietic stem cell transplantation. METHODS: Before transplantation, patients' oral health and inflammatory conditions were determined using the gingival index and the plaque index, which are based on gingival bleeding and the presence of dental plaque, respectively. Additionally, the dental health status was determined using the decayed, missing, and filled teeth index. The monitoring of oral mucositis was based on the World Health Organization grading system and was performed for five periods: from Day 0 to D+5, from D+6 to D+10, from D+11 to D+15, from D+16 to D+20, and from D+21 to D+30. RESULTS: A total of 97 patients (56% male and 44% female) who underwent hematopoietic stem cell transplantation at the Hospital das Clinicas da Faculdade de Medicina da Universidade de Sao Paulo between January 2008 and July 2009 were prospectively examined. The incidence of ulcerative mucositis was highest from days +6 to +10 and from days +11 to +15 in the patients who underwent autologous and allogeneic hematopoietic stem cell transplantation, respectively. CONCLUSION: The data, including the dental plaque and periodontal status data, showed that these oral health factors were predictive of the incidence and severity of oral mucositis in a cohort of patients with similar conditioning regimens before hematopoietic stem cell transplantation.

RESUMO

OBJECTIVE: The objective of this study was to analyze the incidence of and risk factors for healthcare-associated infections (HAI) among hematopoietic stem cell transplantation (HSCT) patients, and the impact of such infections on mortality during hospitalization. METHODS: We conducted a 9-year (2001-2009) retrospective cohort study including patients submitted to HSCT at a reference center in São Paulo, Brazil. The incidence of HAI was calculated using days of neutropenia as the denominator. Data were analyzed using EpiInfo 3.5.1. RESULTS: Over the 9-year period there were 429 neutropenic HSCT patients, with a total of 6816 days of neutropenia. Bloodstream infections (BSI) were the most frequent infection, presenting in 80 (18.6%) patients, with an incidence of 11.7 per 1000 days of neutropenia. Most bacteremia was due to Gram-negative bacteria: 43 (53.8%) cases were caused by Gram-negative species, while 33 (41.2%) were caused by Gram-positive species, and four (5%) by fungal species. Independent risk factors associated with HAI were prolonged neutropenia (odds ratio (OR) 1.07, 95% confidence interval (CI) 1.04-1.10) and duration of fever (OR 1.20, 95% CI 1.12-1.30). Risk factors associated with death in multivariate analyses were age (OR 1.02, 95% CI 1.01-1.43), being submitted to an allogeneic transplant (OR 3.08, 95% CI 1.68-5.56), a microbiologically documented infection (OR 2.96, 95% CI 1.87-4.6), invasive aspergillosis disease (OR 2.21, 95% CI 1.1-4.3), and acute leukemias (OR 2.24, 95% CI 1.3-3.6). CONCLUSIONS: BSI was the most frequent HAI, and there was a predominance of Gram-negative microorganisms. Independent risk factors associated with HAI were duration of neutropenia and fever, and the risk factors for a poor outcome were older age, type of transplant (allogeneic), the presence of a microbiologically documented infection, invasive aspergillosis, and acute leukemia. Further prospective studies with larger numbers of patients may confirm the role of these risk factors for a poor clinical outcome and death in this transplant population.

RESUMO

BACKGROUND: Allogeneic hematopoietic stem cell transplantation with HLA-identical donors has been established for the treatment of acute myeloid leukemia patients for over 30 years with a cure rate of 50 percent to 60 percent. OBJECTIVES: To analyze the overall survival of patients and identify factors that influence the outcomes of this type of transplant in patients in 1st complete remission who received a busulfan and melphalan combination as conditioning regimen. METHODS: Twenty-five consecutive patients with acute myeloid leukemia were enrolled between 2003 and 2008. The median age was 34 years old (Range: 16 - 57 years). All patients received cyclosporine and methotrexate for prophylaxis against graft-versus-host disease. Median neutrophil engraftment time was 16 days (Range: 7 - 22 days) and 17 days (Range: 7 - 46 days) for platelets. Sinusoidal obstructive syndrome was observed in three patients, seven had grade II acute graft-versus-host disease and one extensive chronic graft-versus-host disease. RESULTS: The overall survival by the Kaplan-Meier method was 48 percent after 36 months with a plateau at 36 months after transplantation. Intensive consolidation with high-dose arabinoside resulted in an improved survival (p-value = 0.0001), as did grade II acute graft-versus-host disease (p-value = 0.0377) and mild chronic graft-versus-host disease (p-value < 0.0001). Thirteen patients died, five due to infection within 100 days of transplant, two due to hemorrhages, one to infection and graftversus-host disease and three relapses followed by renal failure (one) and infection (two). The cause of death could not be determined for two patients. CONCLUSION: The busulfan and melphalan conditioning regimen is as good as other conditioning regimens providing an excellent survival rate.

RESUMO

BACKGROUND: Hodgkin's lymphoma has high rates of cure, but in 15 percent to 20 percent of general patients and between 35 percent and 40 percent of those in advanced stages, the disease will progress or will relapse after initial treatment. For this group, hematopoietic stem cell transplantation is considered one option of salvage therapy. OBJECTIVES: To evaluate a group of 106 patients with Hodgkin's lymphoma, who suffered relapse or who were refractory to treatment, submitted to autologous hematopoietic stem cell transplantation in a single transplant center. METHODS: A retrospective study was performed with data collected from patient charts. The analysis involved 106 classical Hodgkin's lymphoma patients who were consecutively submitted to high-dose chemotherapy followed by autologous transplants in a single institution from April 1993 to December 2006. RESULTS: The overall survival rates of this population at five and ten years were 86 percent and 70 percent, respectively. The disease-free survival was approximately 60 percent at five years. Four patients died of procedure-related causes but relapse of classical Hodgkin's lymphoma after transplant was the most frequent cause of death. Univariate analysis shows that sensitivity to pre-transplant treatment and hemoglobin < 10 g/dL at diagnosis had an impact on patient survival. Unlike other studies, B-type symptoms did not seem to affect overall survival. Lactic dehydrogenase and serum albumin concentrations analyzed at diagnosis did not influence patient survival either. CONCLUSION: Autologous hematopoietic stem cell transplantation is an effective treatment strategy for early and late relapse in classical Hodgkin's lymphoma for cases that were responsive to pre-transplant chemotherapy. Refractory to treatment is a sign of worse prognosis. Additionally, a hemoglobin concentration below 10 g/dL at diagnosis of Hodgkin's lymphoma has a negative impact on the survival of patients after transplant. As far as we know this relationship has not been previously reported.
