RESUMO

Chemotherapy-induced neutropenia (FN) is the most common infectious complication in pediatric oncology. To our knowledge, no pediatric research has been published in Tunisia. The purpose of our study was to describe the features of FN among Tunisian children and to investigate factors correlated with FN. We conducted a prospective study of children with chemotherapy-induced FN at the Department of Pediatric Medicine A of the Tunis Children´s Hospital from July 2019 to December 2019. We recorded 50 episodes of FN in 32 patients whose mean age was 5.3 years (3 months-16 years). We included 26 patients with solid tumors (81%) and six patients with hemopathies (18.7%). The mean time between last treatment and fever onset was 10.67 days. Bacteriological investigation was contributory in 18% of cases and mainly showed gram positive cocci. Therapeutic protocol including 1st line empirical antibiotic therapy (3rd generation cephalosporin with aminoglycoside) was effective in 62% of cases. Mortality rate of patients with FN was 2%. The statistical study did not reveal any factor of correlation with late-onset neutropenia. In conclusion, our results are consistent with literature data on bacteriological documentation and mortality. Our 1st line treatment option based on 3rd generation cephalosporin associated with aminoglycoside was effective in 2/3 of the cases. In the future, oral antibiotics may be considered in patients at low risk for infection.

RESUMO

La bacteriemia representa una importante causa de morbimortalidad en pacientes oncológicos. Durante el episodio de neutropenia inducida por quimioterapia, un 15%­25% de los pacientes tendrá bacteriemia. Objetivo: identificar factores de riesgo asociados con bacteriemia en pacientes oncológicos pediátricos con neutropenia y fiebre. Material y métodos: estudio de cohorte prospectivo. Se incluyeron pacientes con enfermedades hematooncológicas y neutropenia febril, internados en un hospital pediátrico de alta complejidad entre julio de 2018 y mayo de 2019. Se excluyeron receptores de trasplante de médula ósea. Se compararon las características clínicas según se documentara bacteriemia (B) o no. Resultados: Se incluyeron 160 pacientes (p). Eran varones 93 (58%). La mediana de edad fue 81,5 meses (RIC 36-127,5). La enfermedad de base (EB) más frecuente fue: leucemia linfoblástica aguda (LLA) 88 (55%). Se identificaron 20 (12,5%) pacientes con bacteriemia (B). En el análisis univariado hubo asociación entre B y LMA (p=0,003) y la internación en UCI (p=0,0001). En el modelo multivariado, ajustado por el resto de las variables, se identificaron la LMA (OR 8,24, IC95% 2,5-26,4; p<0,001) y la tiflitis (OR 5,86, IC95% 1,2-27,3; p=0,02) como factores relacionados con bacteriemia. Los principales microorganismos identificados fueron: estreptococos del grupo viridans 6 (30%), Escherichia coli 4 (20%) y estafilococos coagulasa negativos 3 (15%). Quince (75%) fueron bacteriemias secundarias a un foco clínico. El foco más frecuente fue el mucocutáneo (n=7, 35%). En esta cohorte de niños con cáncer y neutropenia febril, los factores asociados con bacteriemia fueron: la LMA, la tiflitis y la internación en UCI (AU)


Bacteremia is an important cause of morbidity and mortality in oncology patients. During an episode of chemotherapy-induced neutropenia, 15%-25% of patients will develop bacteremia. Objective: to identify risk factors associated with bacteremia in pediatric oncology patients with neutropenia and fever. Material and methods: prospective cohort study. Patients with hematology-oncology diseases and febrile neutropenia, admitted to a tertiary-care pediatric hospital between July 2018 and May 2019 were included. Bone marrow transplant recipients were excluded. Clinical characteristics were compared according to whether or not bacteremia was recorded. Results: 160 patients were included of whom 93 (58%) were male. Median age was 81.5 months (IQR 36-127.5). The most common underlying disease was acute lymphoblastic leukemia (ALL) in 88 patients (55%). Twenty (12.5%) patients with bacteremia were identified. In univariate analysis, an association was found between bacteremia and acute myeloid leukemia (AML) (p=0.003) and ICU admission (p=0.0001). In the multivariate model, adjusted for the remaining variables, AML (OR 8.24; 95%CI 2.5-26.4; p<0.001) and typhlitis (OR 5.86; 95%CI 1.2-27.3; p=0.02) were identified as factors related to bacteremia. The main microorganisms identified were viridans group streptococci in 6 (30%), Escherichia coli in 4 (20%), and coagulase negative staphylococci in 3 (15%). In 15 cases (75%), bacteremia was secondary to a clinical focus. The most frequent focus was mucocutaneous (n=7, 35%). In this cohort of children with cancer and febrile neutropenia, the factors associated with bacteremia were AML, typhlitis, and ICU admission (AU)

RESUMO

INTRODUCTION: This study was conducted to develop and validate a nomogram for predicting the risk of neutropenia or febrile neutropenia (FN) in tumor patients in the first cycle of etoposide-based chemotherapy. METHODS: This retrospective cohort study used an information system to monitor patients with non-Hodgkin's lymphoma or solid tumors receiving an etoposide regimen in the first chemotherapy cycle in our hospital from 2009 to 2020. Binary logistic regression analysis was used to identify the influencing factors of patients with neutropenia or FN. Those factors were then used to develop a nomogram. RESULTS: A total of 1,554 patients were divided into the development group (n = 1,072) and validation group (n = 482). Variables used to predict neutropenia or FN were Karnofsky performance status (odds ratio [OR] = 0.85, 95% confidence interval [CI] = 0.81-0.89, p < 0.01), metastatic sites ≥3 (OR = 6.33, 95% CI = 2.66-15.11, p < 0.01), comorbidity of heart disease (OR = 4.88, 95% CI = 1.74-13.67, p < 0.01), recent surgery (OR = 7.96, 95% CI = 1.96-32.36, p < 0.01), administration of alkylating agents (OR = 4.50, 95% CI = 1.10-18.48, p < 0.01), total bilirubin ≥25 µmol/L (OR = 11.42, 95% CI = 4.00-32.61, p < 0.01), and lymphocyte count <0.7 × 109/L (OR = 4.22, 95% CI = 2.00-9.75, p < 0.01). CONCLUSION: This model can aid the early identification and screening of the potential risk of neutropenia or FN in the first cycle of treatment for patients using etoposide-based chemotherapy.

RESUMO

Patients undergoing myeloablative chemotherapy and hematopoietic stem cell transplantation (HSCT) experience profound neutropenia and vulnerability to infection. Previous research has indicated that patients with infections have depleted vitamin C status. In this study, we recruited 38 patients with hematopoietic cancer who were undergoing conditioning chemotherapy and HSCT. Blood samples were collected prior to transplantation, at one week, two weeks and four weeks following transplantation. Vitamin C status and biomarkers of inflammation (C-reactive protein) and oxidative stress (protein carbonyls and thiobarbituric acid reactive substances) were assessed in association with febrile neutropenia. The vitamin C status of the study participants decreased from 44 ± 7 µmol/L to 29 ± 5 µmol/L by week one (p = 0.001) and 19 ± 6 µmol/L by week two (p < 0.001), by which time all of the participants had undergone a febrile episode. By week four, vitamin C status had increased to 37 ± 10 µmol/L (p = 0.1). Pre-transplantation, the cohort comprised 19% with hypovitaminosis C (i.e., <23 µmol/L) and 8% with deficiency (i.e., <11 µmol/L). At week one, those with hypovitaminosis C had increased to 38%, and at week two, 72% had hypovitaminosis C, and 34% had outright deficiency. C-reactive protein concentrations increased from 3.5 ± 1.8 mg/L to 20 ± 11 mg/L at week one (p = 0.002), and 119 ± 25 mg/L at week two (p < 0.001), corresponding to the development of febrile neutropenia in the patients. By week four, these values had dropped to 17 ± 8 mg/L (p < 0.001). There was a significant inverse correlation between C-reactive protein concentrations and vitamin C status (r = -0.424, p < 0.001). Lipid oxidation (thiobarbituric acid reactive substances (TBARS)) increased significantly from 2.0 ± 0.3 µmol/L at baseline to 3.3 ± 0.6 µmol/L by week one (p < 0.001), and remained elevated at week two (p = 0.003), returning to baseline concentrations by week four (p = 0.3). Overall, the lowest mean vitamin C values (recorded at week two) corresponded with the highest mean C-reactive protein values and lowest mean neutrophil counts. Thus, depleted vitamin C status in the HSCT patients coincides with febrile neutropenia and elevated inflammation and oxidative stress.

RESUMO

BACKGROUND: Fungal infections are a major complication of neutropaenia following chemotherapy. Their early diagnosis is difficult, and empirical antifungal treatment is widely used, and uses of less toxic drugs that reduce breakthrough infection are required. OBJECTIVE: We conducted a multicentre, open-label, randomised, non-inferiority trial to compare the safety and efficacy of intravenous itraconazole (ivITCZ) and liposomal amphotericin B (LAmB) as empirical antifungal therapy in patients with haematological malignancies with neutropaenia and persistent fever. METHODS: Patients with haematological malignancies who developed fever refractory to broad-spectrum antibacterial agents under neutropaenia conditions were enrolled. Patients were randomised for treatment with LAmB (3.0 mg/kg/d) or ivITCZ (induction: 400 mg/d, maintenance: 200 mg/d). RESULTS: Observed overall favourable response rates of 17/52 (32.7%) and 18/50 (36.0%) in the LAmB and ivITCZ groups, with a model-based estimate of a 4% difference (90% CI, -12% to 20%), did not fulfil the statistical non-inferiority criterion. In the LAmB group, there were two cases of breakthrough infection and five cases of probable invasive fungal disease, whereas in the itraconazole group, neither breakthrough infection nor probable invasive fungal disease occurred. Patients in the ivITCZ group had significantly fewer grade 3-4 hypokalaemia-related events than LAmB group patients (P < .01). The overall incidence of adverse events tended to be lower in the ivITCZ group (P = .07). CONCLUSION: ivITCZ showed similar efficacy and safety as LAmB as empirical antifungal therapy in haematological malignancy patients with febrile neutropaenia, although the small sample size and various limitations prevented demonstration of its non-inferiority.

RESUMO

BACKGROUND: Invasive fungal disease is a major cause of morbidity and mortality in children with cancer and high-risk febrile neutropenia (HRFN). Repeated serum galactomannan (sGM) measurements have been described as an effective tool to guide therapy in adults under suspicion of invasive aspergillosis. However, the utility of this approach has not been reported in paediatric population. OBJECTIVES: To evaluate the usefulness of sGM measurements in initiating and modifying antifungal therapy (AFT) in children with cancer and persistent HRFN. PATIENTS/METHODS: Nested case-control study in children with cancer and persistent HRFN episodes, between July 2013 and January 2019. Patients were classified as cases and controls depending on if they received AFT or not, respectively. Through odds ratio analysis, we assessed the role of sGM positivity in the AFT initiation decision. Then, we analysed the group of patients that initiated AFT, and compared those who had AFT modifications and those who did not, analysing different sGM kinetics thresholds. RESULTS: A total of 191 episodes from children with persistent HRFN were enrolled, of which 107 received AFT and 84 did not. The median age was 7 years (IQR 4-12), 52% were male and 89% had a haematologic malignancy as underlying disease. Positive sGM was not associated with AFT initiation (OR 0.99, 95% CI 0.43-2.33, P = .99). A difference threshold in sGM Δ ≥ 0.3 sGM was significantly associated with AFT modification (OR 5.07, 95% CI 1.02- 25.70, P = .04). CONCLUSIONS: Our results suggest the utility of serial sGM sampling during AFT in children with persistent HRFN.

RESUMO

BACKGROUND: Bacillus cereus sometimes causes central nervous system infection, especially in compromised hosts. In cases of meningitis arising during neutropenia, CSF abnormalities tend to be subtle and can be easily overlooked, and mortality rate is high. We report a survived case of B. cereus meningitis/brain abscess in severe neutropenia, presenting as immune reconstitution syndrome. CASE PRESENTATION: A 54-year-old Japanese female with acute myelogenous leukemia developed B. cereus bacteremia and meningitis during consolidation chemotherapy. At the onset, she presented with mild meningism. She had marked leukocytopenia (WBC <100/µL, neutrophils 0/µL) and lumbar puncture yielded only mild pleocytosis. She was transferred to intensive care unit, and meropenem, linezolid and vancomycin was started. With intensive therapy, she recovered and once became afebrile. On day 19, however, her fever, meningism and consciousness level dramatically worsened despite recovery of bone marrow function. The antimicrobial chemotherapy was continued and finally she was cured with no complications. CONCLUSIONS: With early diagnosis and prompt initiation and of antibiotics, the case was successfully treated without any sequelae. It is important to remember that, even under optimal antimicrobial therapy, bone marrow recovery can cause transient reaggravation of the disease. In such cases, timely and appropriate evaluation should be done to make the clinical decision to change, continue, or intensify treatment.

RESUMO

Background/aim: Bacteremia remains an important cause of morbidity and mortality during febrile neutropenia (FN) episodes. We aimed to define the risk factors for bacteremia in febrile neutropenic children with hemato-oncological malignancies. Materials and methods: The records of 150 patients aged ≤18 years who developed FN in hematology and oncology clinics were retrospectively evaluated. Patients with bacteremia were compared to patients with negative blood cultures. Results: The mean age of the patients was 7.5 ± 4.8 years. Leukemia was more prevalent than solid tumors (61.3% vs. 38.7%). Bacteremia was present in 23.3% of the patients. Coagulase-negative staphylococci were the most frequently isolated microorganism. Leukopenia, severe neutropenia, positive peripheral blood and central line cultures during the previous 3 months, presence of a central line, previous FN episode(s), hypotension, tachycardia, and tachypnea were found to be risk factors for bacteremia. Positive central line cultures during the previous 3 months and presence of previous FN episode(s) were shown to increase bacteremia risk by 2.4-fold and 2.5-fold, respectively. Conclusion: Presence of a bacterial growth in central line cultures during the previous 3 months and presence of any previous FN episode(s) were shown to increase bacteremia risk by 2.4-fold and 2.5-fold, respectively. These factors can predict bacteremia in children with FN.

RESUMO

BACKGROUND: Piperacillin-tazobactam is commonly used in neutropenic sepsis at standard doses that do not account for inter-individual differences in age, bodyweight and renal function. This study was designed to assess the rate of attainment of pharmacokinetic/pharmacodynamic (PK/PD) targets in patients receiving piperacillin/tazobactam therapy and to evaluate the effect on clinical outcomes. METHODS: Patients undergoing intensive chemotherapy for aggressive hematological malignancies were enrolled and treated with piperacillin/tazobactam 4 g/0.5 g every 6 h as initial antimicrobial therapy for first fever. Plasma drug concentrations were assayed at 50% and 100% of the dosing interval and compared with target MIC breakpoint of 16 mg/L to calculate the primary endpoints of 50% and 100% time above MIC (fT > MIC), respectively. Secondary endpoints included time to clinical cure, length of hospital stay, duration of antibiotics, and clinical treatment success. RESULTS: Fifty-eight percent (14/24) of patients achieved 50% fT > MIC while only 4% (1/24) achieved 100% fT > MIC. Higher creatinine clearance was significantly associated with lower trough drug concentration and appeared to be the dominant reason for the poor PK/PD target attainment. Median time to clinical cure, duration of antibiotic therapy, and hospital length of stay was 3, 13 and 21 days, respectively. There were no statistically significant differences in these outcomes between patients who did and did not achieve 100% fT > MIC. CONCLUSIONS: A significant majority of febrile neutropenic patients fail to achieve PK/PD targets with 6-hourly piperacillin dosing, although the clinical implications of this finding are unclear. Larger studies are needed to assess any impact on morbidity and mortality. This trial is registered on the ANZCTR (ACTRN12618000110280).

RESUMO

Raoultella planticola is a gram-negative, encapsulated, aerobic bacterium within the Enterobacteriaceae family. It has been primarily described as pathogen in cases with pneumonia and gastrointestinal infections. Here we describe a case of severe pelvic cellulitis in a patient with neutropenia following induction therapy for myeloid sarcoma. The patient experienced a septic shock and was treated successfully with antibiotic therapy. A literature review is provided to put this case in context with previous reports on R. planticola. This report highlights that awareness for uncommon pathogens is crucial in the clinical management of infections in neutropenic patients.

RESUMO

BACKGROUND: Posaconazole is used for the prophylaxis of invasive fungal disease (IFD). Previous studies have shown it to be cost-effective compared to fluconazole/itraconazole. However, posaconazole has never been economically evaluated in developing countries. AIMS: The aim of the present study was to perform a cost-effectiveness analysis of posaconazole compared to fluconazole in public (SUS) and private hospitals (PHS) in Brazil. METHODS: A cost-effectiveness simulation was conducted on the basis of a pivotal study on the use of posaconazole in acute myeloid leukemia (AML) patients, adjusting the costs to Brazilian data. RESULTS: A pharmacoeconomic analysis was performed on a hypothetical sample of 100 patients in each drug group. The total cost of posaconazole use alone was USD$ 220,656.31, whereas that for fluconazole was USD$ 83,875.00. Our results showed that patients with IFD remain hospitalized for an additional 12 days, at an average cost of USD$ 850.85 per patient per day. The total money spent by PHS for 100 patients for 100 days was USD$ 342,318.00 for the posaconazole group and USD$ 302,039.00 for the fluconazole group. An analysis of sensitivity (10%) revealed no intergroup difference. CONCLUSIONS: In Brazil posaconazole is cost-effective, and should be considered for the prophylaxis of patients with AMD/myelodysplasia (AML/MDS) undergoing chemotherapy.

RESUMO

OBJECTIVES: To study the management of chronic disseminated candidiasis (CDC) in patients presenting with acute leukemia. PATIENTS AND METHODS: Single-center retrospective study of acute leukemia patients (2006-2015) to investigate three aspects of CDC: its impact on the time interval between diagnosis and hematopoietic stem cell transplantation, when required (non-parametric Wilcoxon-Mann-Whitney test); its impact on overall survival (Cox proportional hazard regression model); antifungal therapeutic strategies implemented. RESULTS: A total of 639 patients presenting with acute leukemia were included; 144 were transplanted and 29 developed CDC. CDC did not significantly increase the time interval between diagnosis and transplantation, nor did it impact the overall survival of recipients. An improved overall survival was observed in non-transplanted acute leukemia patients presenting with CDC. CONCLUSION: CDC should not postpone transplantation if antifungal treatment is optimized.

RESUMO

PURPOSE: To validate a clinical risk prediction score (Ammann score) to predict adverse events (AEs) in paediatric febrile neutropenia (FN). PATIENTS AND METHODS: Patients <16 years of age were enrolled. A risk prediction score (based on haemoglobin ≥ 9 g/dl, white cell count (WCC) < 0.3 G/l, platelet count <50 G/l and chemotherapy more intensive than acute lymphoblastic leukaemia maintenance therapy) was calculated and AEs were documented. RESULTS: In total, 100 FN episodes occurred in 52 patients, male:female ratio was 1.8:1 and median age was 56 months. At reassessment, AEs occurred in 18 of 55 (45%) low-risk FN episodes (score < 9) and 21 of 42 (55%) high-risk episodes (score ≥9) (sensitivity 60%, specificity 65%, positive predictive value 53%, negative predictive value 71%). Total WCC and absolute monocyte count (AMC) were significantly associated with AEs. CONCLUSION: This study identified total WCC and AMC as significantly associated with AEs but failed to validate the risk prediction score.

RESUMO

Fever and neutropenia is an oncologic emergency. Time-to-antibiotics (TTA) refers to the amount of time from initial provider evaluation for fever and neutropenia to intravenous antibiotic administration. Research supports that rapid time-to-antibiotics (RTTA) is associated with improved patient outcomes. This quality improvement project evaluated the success of implementing an RTTA pathway in pediatric oncology patients with fever and neutropenia. The setting was an advanced practice nurse-managed pediatric ambulatory infusion center where patients with fever and neutropenia were often evaluated and treated. In order to improve TTA, a multidisciplinary pathway was implemented with a goal of TTA that was less than 60 minutes from initial provider evaluation. Implementation of the RTTA pathway included discussion of shared expectations with the pharmacy and education departments and discussion of shared expectations with the bedside nurses and advanced practice nurses staffing the unit. Additionally, a preliminary lab test was utilized. Success of the implementation was evaluated through 2 measures: TTA and nurses' knowledge of fever and neutropenia and the importance of RTTA. The aims of this project were to improve TTA as well as nurses' knowledge of fever and neutropenia and the importance of RTTA, and both these aims were successfully attained.

RESUMO

BACKGROUND: A new 23S ribosomal RNA genes-targeted in situ hybridization (ISH) probe to detect global bacterial genomic DNA (59 species from 35 genera; referred to as the GB probe) phagocytized in leukocytes was recently developed. This method provided early and direct evidence of bacterial infection with high sensitivity and specificity in spontaneous bacterial peritonitis ascites. However, the utility of this method in febrile neutropenia (FN) is unknown. METHODS: We prospectively evaluated the utility of the ISH approach using the GB probe and previously reported probes in patients with neutropenia and fever undergoing chemotherapy at our institution between June 2011 and July 2013. Blood samples for culture analysis and ISH tests were collected simultaneously at the onset of fever; the latter were performed repeatedly. RESULTS: Fifty febrile episodes were evaluated. In 24 episodes of fever of unknown origin and 15 episodes of local infection (all negative for blood cultures), ISH tests identified causal bacteria in 21% and 13% of cases, respectively, at the onset of fever. In seven sepsis cases (all positive for blood culture), positive ISH test results at fever onset were achieved in 71%; for two patients with neutrophil counts of 0/µl and 171/µl, respectively, negative results were obtained. CONCLUSIONS: This new ISH approach could prove useful for early detection of bacteria in patients with neutropenia and blood culture-negative, with fever of unknown etiology after chemotherapy. Using this method in combination with blood culture, even in cases with extremely low neutrophil counts, might contribute to better management of FN.

RESUMO

Introduction: Invasive fungal infection is among the leading causes of morbidity, mortality, and economic burden for patients with acute leukemia after induction of chemotherapy. In the past few decades, the incidence of invasive fungal infection has increased dramatically. Its management has been further complicated by the increasing frequency of infection by non-Aspergillus molds (e.g. Mucorales). Neutropenic patients are at a high risk of developing an invasive mucormycosis with fulminant course and high mortality rate (35­100%). Case Outline: We are presenting the case of a 72-year-old male with an acute monoblastic leukemia. The patient was treated during five days with hydroxycarbamide 2 × 500 mg/day, followed by cytarabine 2 × 20 mg/sc over the next 10 days. He developed febrile neutropenia, headache, and edema of the right orbital region of the face. Computed tomography of the sinuses revealed shadow in sinuses with thickening of mucosa of the right paranasal sinuses. Lavage and aspirate from the sinuses revealed Rhizopus oryzae. Mucormycosis was successfully treated with amphotericin B (5 mg/kg/day) followed by ketoconazole (400 mg/day). Two months later the patient died from primary disease. Conclusion: In patients with acute leukemia who developed aplasia, febrile neutropenia, and pain in paranasal sinuses, fungal infection should be taken into consideration. New and non-invasive methods for taking samples from sinuses should be standardized in order to establish an early and accurate diagnosis of mucormycosis with the source in paranasal sinuses, and to start early treatment by a proper antifungal drug. Clear communication between physician and mycologist is critical to ensure proper and timely sampling of lavage and aspirate from sinuses and correct specimen processing when mucormycosis is suspected clinically.

RESUMO

OBJECTIVES: To describe the French routine use of G-CSF in patients treated for breast cancer as per the EORTC recommendations. PATIENTS AND METHODS: A prospective multicenter observational study conducted between February 2008 and September 2009 in 869 breast cancer patients treated by chemotherapy (CT) and for whom G-CSF treatment will be delivered in primary (PP) or secondary prophylaxis. RESULTS: The mean age was 55 years. A total of 80.3% of CT was in neoadjuvant/adjuvant setting (NAS). PP was delivered in 78.9% of the NAS patients and 67.5% in metastatic situation. Of the 702 evaluable patients, incidences of severe (SN) and febrile neutropenias (FN) in patients who received PP were 9.3% and 4.2%, respectively. In patients who did not received G-CSF at first cycle, SN and FN were 12.4% and 7.3%, respectively. The use of PP was mainly driven by the type of CT for patients treated in the NAS and by patient or disease related risk factors in the locally advanced/metastatic setting. CONCLUSION: This study has shown that the use of G-CSF was in accordance with the 2010 updates of the EORTC recommendations. However, G-CSF appears more widely used in the routine practice.
