RESUMO

Bloodstream infections (BSI) are a frequently observed complication after hematopoietic stem cell transplant (HSCT). Retrospective analysis of clinical and microbiological data during the first 100 days from 302 consecutive pediatric patients who underwent HSCT for a malignant disease at our institute between January 2013 and June 2017. A total of 164 patients underwent autologous and 138 allogeneic HSCT. The overall incidence of BSI was 37% with 92% of infectious episodes occurring during the pre-engraftment phase. Gram-positive bacteria (GPB) accounted for 54.6% of the isolated pathogens, gram-negative bacteria (GNB) for 43.9%, and fungi for 1.4%. Coagulase-negative staphylococci and Escherichia coli were the most commonly isolated GPB and GNB, respectively. Forty-five percent of GNB were extended-spectrum beta-lactamase producers and 21% were multidrug-resistant organisms. Fluoroquinolone resistance was 92% and 68%, among GPB and GNB, respectively. Risk factors for BSI in univariate analysis were allogeneic HSCT, delayed time to engraftment more than 12 days, previous BSI before HSCT, and alternative donor. In multivariate analysis, only HSCT type (allogeneic vs autologous P = .03) and previous BSI within 6 months before HSCT (P = .016) were significant. Overall survival at day 100 was 98% and did not differ significantly between patients with and without BSI (P = .76). BSI is common in children undergoing HSCT for malignant diseases. Allogeneic HSCT recipients and previous BSI within 6 months before HSCT are associated with increased risk of post-transplant BSI. With current supportive measures, BSI does not seem to confer an increased risk for 100-day mortality.

RESUMO

BACKGROUND/PURPOSE: For high risk of central line-associated bloodstream infections (CLABSIs) in patients of intensive care units (ICUs) and scarcely epidemiology and therapeutic recommendations in Asia, we aimed to evaluate the annual change in epidemiology, antibiogram, and risk factors for 14-day mortality. METHODS: A retrospective study of ICUs patients with CLABSIs at a medical center in Taiwan (2010-2016), where central line care bundle implemented since 2014, by reviewing clinical data, pathogens, and the antibiogram. RESULTS: Gram-negative bacteria (59.3%) were main microorganisms of CLABSIs, and 9.0% of all GNB were MDROs. Acinetobacter spp., Enterobacter spp., and Stenotrophomonas maltophilia were the most frequently isolated. In multivariate analysis, malignancy, inadequate empirical antimicrobial therapy, inadequate definite antimicrobial therapy, and infection by fungi or multidrug-resistant organisms (MDROs) were associated with 14-day mortality (all p < 0.05). The CLABSI incidence rate decreased from 5.54 to 2.18 per 1000 catheter-day (from 2014 to 2015) with improved compliance to care bundle. Carbapenem and aminoglycoside were suitable empirical drugs in the hospital setting when GNB is predominant for CLABSI. Significant decreasing susceptibility of ampicillin/sulbactam in Enterobacter spp. (36.7%-0.0%), and ampicillin/sulbactam (12.5%-0.0%), ceftazidime (100.0%-52.9%), and tigecycline (87.5%-35.3%) in Serratia marcescens. CONCLUSION: We identified Gram-negative bacteria as leading pathogens of CLABSIs in a Taiwan medical center, and good compliance to care bundle is associated with reduced CLABSI incidence rate. Malignancy, infection by MDROs or fungi, inadequate empirical or definite antimicrobial therapy are significant factors for 14-day mortality.

RESUMO

The epidemiology of invasive fungal disease (IFD) due to filamentous fungi other than Aspergillus may be changing. We analysed clinical, microbiological and outcome data in Australian patients to determine the predisposing factors and identify determinants of mortality. Proven and probable non-Aspergillus mould infections (defined according to modified European Organization for Research and Treatment of Cancer/Mycoses Study Group criteria) from 2004 to 2012 were evaluated in a multicentre study. Variables associated with infection and mortality were determined. Of 162 episodes of non-Aspergillus IFD, 145 (89.5%) were proven infections and 17 (10.5%) were probable infections. The pathogens included 29 fungal species/species complexes; mucormycetes (45.7%) and Scedosporium species (33.3%) were most common. The commonest comorbidities were haematological malignancies (HMs) (46.3%) diabetes mellitus (23.5%), and chronic pulmonary disease (16%); antecedent trauma was present in 21% of cases. Twenty-five (15.4%) patients had no immunocompromised status or comorbidity, and were more likely to have acquired infection following major trauma (p <0.01); 61 (37.7%) of cases affected patients without HMs or transplantation. Antifungal therapy was administered to 93.2% of patients (median 68 days, interquartile range 19-275), and adjunctive surgery was performed in 58.6%. The all-cause 90-day mortality was 44.4%; HMs and intensive-care admission were the strongest predictors of death (both p <0.001). Survival varied by fungal group, with the risk of death being significantly lower in patients with dematiaceous mould infections than in patients with other non-Aspergillus mould infections. Non-Aspergillus IFD affected diverse patient groups, including non-immunocompromised hosts and those outside traditional risk groups; therefore, definitions of IFD in these patients are required. Given the high mortality, increased recognition of infections and accurate identification of the causative agent are required.

RESUMO

The number of emerging organisms causing invasive fungal infections has increased in the last decades. These etiological agents include Scedosporium, Fusarium and mucorales. All of them can cause disseminated, virulent, and difficult-to treat infections in immunosuppressed patients, the most affected, due to their resistance to most available antifungal agents. Current trends in transplantation including the use of new immunosuppressive treatments, the common prescription of antifungal agents for prophylaxis, and new ecological niches could explain the emergence of these fungal pathogens. These pathogens can also affect immunocompetent individuals, especially after natural disasters (earthquakes, floods, tsunamis), combat wounds or near drowning. All the invasive infections caused by Scedosporium, Fusarium, and mucorales are potentially lethal and a favourable outcome is associated with rapid diagnosis by direct microscopic examination of the involved tissue, wide debridement of infected material, early use of antifungal agents including combination therapy, and an improvement in host defenses, especially neutropenia.

RESUMO

Chronic granulomatous disease (CGD) is a primary immunodeficiency characterized by recurrent infections and a dysregulated inflammatory response. Infection-triggered hemophagocytic lymphohistiocytosis (HLH), which manifests itself as pathologic hyperactive inflammation, has been observed in subjects with CGD. However, there have been no reports of HLH as the initial presentation with subsequent diagnosis of CGD. Furthermore, the primary therapeutic strategy for HLH focuses on immunosuppressive therapies, which limits immune-mediated tissue damage. With immunodeficiency, this therapeutic strategy may worsen the outcome. This article discusses an 8-week-old Hispanic male who presented with fever of unknown origin. The initial diagnostic evaluation demonstrated pathologic hyperactive inflammation, meeting the HLH-2004 diagnostic criteria without an identified infectious etiology. Immunosuppressive therapy was initiated, with subsequent disseminated candida septic shock and sepsis-induced multisystem organ failure. Additional evaluations ultimately established the diagnosis of CGD. We transitioned to an immune-enhancing strategy with granulocyte and immunoglobulin infusions, and intensified antifungal therapies. These interventions ultimately led to the clearance of the fungal infection and the resolution of the hyperactive inflammatory state. This case represents the first reported case of HLH as the presenting finding leading to the subsequent diagnosis of CGD. It serves as a reminder that both immunodeficiency and inflammatory disorders may share features of pathologic hyperactive inflammation and highlights the conundrum that clinicians face when treating HLH in the setting of an unresolved infection. In this case report, we demonstrate that immune-enhancing therapies may aid in the control and the clearance of the infection, thus paradoxically decreasing the pathologic hyperactive inflammatory response.

RESUMO

INTRODUCTION: Fungal sepsis is an increasingly common problem in intensive care unit patients.Mortality from fungal sepsis remains high despite antimicrobial therapy that is highly active against most fungal pathogens, a finding consistent with defective host immunity that is present in many patients with disseminated fungemia.One recently recognized immunologic defect that occurs in patients with sepsis is T cell "exhaustion" due to increased expression of programmed cell death -1 (PD-1).This study tested the ability of anti-PD-1 and anti-programmed cell death ligand -1 (anti-PD-L1) antagonistic antibodies to improve survival and reverse sepsis-induced immunosuppression in two mouse models of fungal sepsis. METHODS: Fungal sepsis was induced in mice using two different models of infection, that is, primary fungal sepsis and secondary fungal sepsis occurring after sub-lethal cecal ligation and puncture (CLP).Anti-PD-1 and anti-PD-L1 were administered 24 to 48 h after fungal infection and effects on survival, interferon gamma production, and MHC II expression were examined. RESULTS: Anti-PD-1 and anti-PD-L1 antibodies were highly effective at improving survival in primary and secondary fungal sepsis.Both antibodies reversed sepsis-induced suppression of interferon gamma and increased expression of MHC II on antigen presenting cells.Blockade of cytotoxic T-lymphocyte antigen-4 (CTLA-4), a second negative co-stimulatory molecule that is up-regulated in sepsis and acts like PD-1 to suppress T cell function, also improved survival in fungal sepsis. CONCLUSIONS: Immuno-adjuvant therapy with anti-PD-1, anti-PD-L1 and anti-CTLA-4 antibodies reverse sepsis-induced immunosuppression and improve survival in fungal sepsis.The present results are consistent with previous studies showing that blockade of PD-1 and CTLA-4 improves survival in bacterial sepsis.Thus, immuno-adjuvant therapy represents a novel approach to sepsis and may have broad applicability in the disorder.Given the relative safety of anti-PD-1 antibody in cancer clinical trials to date, therapy with anti-PD-1 in patients with life-threatening sepsis who have demonstrable immunosuppression should be strongly considered.

RESUMO

In adults, hepatic complications after allogeneic hematopoietic stem cell transplantation (allo-HSCT) are associated with significant morbidity and transplantation-related mortality (TRM). However, there is a paucity of parallel data on the incidence of, and risk factors for, liver injury (LI) and the impact of LI on TRM in pediatric allo-HSCT recipients. We compared total bilirubin, direct bilirubin, and alanine aminotransferase values before allo-HSCT and at 1 month, day +100, and 12 months after allo-HSCT in 248 patients who received either a myeloablative conditioning (MAC) regimen (n = 109) or a reduced-toxicity/reduced-intensity conditioning (RTC/RIC) regimen (n = 139). LI was defined as grade ≥ 2 hyperbilirubinemia according to the National Cancer Institute's Common Terminology Criteria for Adverse Events 3.0/4.0 (total bilirubin, >1.95 mg/dL, 1.5 times above the upper limit of normal for our laboratory). Univariate and multivariate logistic regression models were used to identify risk factors for LI and TRM. The incidence of LI at 1 month after allo-HSCT was 14.1%. The median bilirubin level was 3.5 mg/dL (range, 1.97 to 32.2 mg/dL). Only LI as defined by total bilirubin level, but not by direct bilirubin or alanine aminotransferase level, was found to be a significant predictor for TRM. The 1-year TRM was 60.7% (95% confidence interval, 42.6% to 78.7%) in patients with LI at 1 month after allo-HSCT, compared with 14.6% (95% confidence interval, 9.9% to 19.4%) (P < .0001) in patients those who did not have liver injury. Multivariate analysis identified age (P = .03), total body irradiation (P = .007), bacterial bloodstream infection (BBSI) (P = .001), and invasive fungal infection (IFI) (P = .002) as significant risk factors for developing LI at 1 month. On multivariate analysis for risk factors for TRM, only LI at 1 month after allo-HSCT (P < .0001), primary graft failure (P = .001), BBSI (P = .003), and systemic viral infection (P = .04) were identified as significant risk factors for TRM. LI before allo-HSCT conditioning was not associated with higher TRM. Although the incidence of LI in pediatric allo-HSCT recipients is low, LI is associated with very high TRM. BBSI and IFI are the primary risk factors for LI.

RESUMO

Several data support the view that impairment of the inflammatory-immune response is a hallmark of severe sepsis and the level and time of recovery to immunocompetence has a major impact on the clinical outcome of ICU patients. Recent studies demonstrate that improvement of anti-tumour immune response by targeting negative regulatory molecules, such as CD25, chronic T-lymphocyte activation antigen 4, and programmed death-1 receptor (PD-1)/PD-1 L, offers a novel opportunity to prevent or even reverse progression of tumour growth in experimental models and patients. Likewise, severe sepsis is associated with enhanced expression of those negative regulatory molecules, suggesting a novel approach to reverse immunoparalysis in sepsis. Consequently, targeting negative molecules in sepsis can reverse immunoparalysis and improve survival in experimental sepsis, as shown by Chang and colleagues in a recent issue of Critical Care. This opens new opportunities to overcome overwhelming downregulation of the adaptive immune response to prevent and/or improve recovery from sepsis.

RESUMO

HISTORY: Small bowel resection had to be performed because of an acute ileus in a 16-year old girl with mucoviscidosis. Severe respiratory insufficiency developed and she was transferred to the intensive care unit. INVESTIGATIONS: The clinical signs of a severe ARDS were demonstrated: Horowitz index < 200, pO (2) 57 mm Hg, FiO (2) 1,0, pCO (2) 82 mm Hg. Candida serology was positive (titer 1 : 5120), and there was a leukocytosis (20 000/µl), hypalbuminemia (14 g/l) and elevation of C-reactive protein (190 mg/l). TREATMENT AND COURSE: Because all non invasive treatment options had failed to improve the patient's condition, an extracorporal membrane oxygenation (ECMO) device was connected. Seven days later, after the pulmonary situation had improved, the device was successfully removed; the patient was discharged in a satisfactory condition after another month. CONCLUSION: ECMO is a another treatment option for serious ARDS in infection-related worsening of pulmonary cystic fibrosis.

RESUMO

Invasive fungal disease by Candida spp. is on the rise in the modem era of prolonged patient survival by virtue of improved critical care measures, novel chemotherapy regimens, and increasing immunosuppression following organ transplants. Invasive candidiasis (IC) in the setting of an intensive care unit results in prolonged hospital stay and increased morbidity. Clinical suspicion plays a major role in the diagnosis of IC, as current laboratory methods are not very sensitive. Various serum markers and molecular techniques are under development to improve diagnostic strategies. Treatment options involve an expanding spectrum of antifungals. Knowledge of local epidemiology and the risk factors that predispose patients to this disease are essential for effective patient care in an intensive care setting.

RESUMO

OBJECTIVE: To explore the impact of retention of non-tunneled central venous catheters (CVCs) on survival in candidemic cancer patients, where CVCs are commonly used and essential. A second object was to determine whether early CVC removal would benefit a subset of cancer patients. METHODS: We retrospectively evaluated 92 cancer patients who had a single, non-tunneled CVC in place. Patients were grouped according to CVC retention or removal; the later group was subdivided into early (CVC removed

RESUMO

OBJECTIVE: To analyze the incidence, clinical features and the predisposing factors of fungal septicemia, and investigate the risk factors for death due to fungal septicemia and the prognosis of the patients. METHODS: We retrospectively analyzed the clinical data of 91 patients with fungal septicemia diagnosed in the last 17 years, including 60 patients with clinical cure or improvement, and 31 who die of the disease. Based on the results by univariate analysis, the data were analyzed using logistic multiple regression and Fisher's discriminant analysis. RESULTS: Fungal septicemia had many predisposing factors with high mortality rate. Univariate analysis revealed significant differences between the cured/improved cases and the fatal cases for 12 variables, including advanced age, complication by bacterial infection, septic shock, multiple organ dysfunction syndrome (MODS), ICU patients, cortical hormone therapy, surgery, chemotherapy, use of immunopotentiating agents, length of hospital stay before antifungal therapy, time of anti-fungus therapy and types of invasive procedures. Logistic multiple regression analysis showed that the types of invasive procedures, MODS, surgery and prolonged hospital stay before antifungal therapy were the independent risk factors for fungal septicemia-related death. Fisher's linear discriminant equation was established for predicting the prognosis of the disease. CONCLUSION: The types of invasive procedure, MODS, surgery and prolonged hospital stay before antifungal therapy are the independent risk factors for fungal septicemia-related death, and the patients' prognosis can be predicted using Fisher's linear discriminant equation.

RESUMO

Invasive fungal infections (IFI) are an important complication in hematologic malignancies and stem-cell transplantation (SCT). However, there are limited data characterizing IFI in children. The clinical feature of IFI after chemotherapy and SCT were analyzed in 334 pediatric patients treated at Hokkaido University Hospital from 1997 to 2006. The cumulative incidence of IFI was 6.9%; this comprised cases of proven, probable and possible IFI at rates of 1.2%, 3.0%, and 2.7%, respectively. The infected lesions were lung in 14 patients, liver in 5 patients, brain in 3 patients, fungemia in 2 patients, kidney in 1 patient, and endophthalmitis in 1 patient. The mortality of IFI was 48.2%, excluding patients who died due to relapse and interstitial pneumonitis; in particular, 71.4% patients with a lung lesion (10/14) died due to IFI. Fifty-nine pediatric patients died in our institution over the 10-year period of the study and IFI was the direct cause of death in 18.6% (11/59) of the patients. Risk factors for IFI with chemotherapy and SCT were also analyzed. Univariate analysis showed that age at diagnosis older than 10 years, relapse of original disease, long-term administration of broad-spectrum antibiotics, and acute myelogenous leukemia (AML) were the risk factors for IFI. All patients with IFI received long-term antibiotic therapy. AML was most strongly associated using a multivariate analysis. The prognosis of IFI has been expected poor; therefore, prevention of this condition, especially for older patients with AML, would be important.

RESUMO

BACKGROUND: Opportunistic invasive fungal infections are increasingly frequent in intensive care patients. Their clinical spectrum goes beyond the patients with malignancies, and for example invasive pulmonary aspergillosis has recently been described in critically ill patients without such condition. Liver failure has been suspected to be a risk factor for aspergillosis. CASE PRESENTATION: We describe three cases of adult respiratory distress syndrome with sepsis, shock and multiple organ failure in patients with severe liver failure among whom two had positive Aspergillus antigenemia and one had a positive Aspergillus serology. In all cases bronchoalveolar lavage fluid was positive for Aspergillus fumigatus. Outcome was fatal in all cases despite treatment with voriconazole and aggressive symptomatic treatment. CONCLUSION: Invasive aspergillosis should be among rapidly raised hypothesis in cirrhotic patients developing acute respiratory symptoms and alveolar opacities.

RESUMO

Population-based surveillance for candidemia in Australia from 2001 to 2004 identified 1,095 cases. Annual overall and hospital-specific incidences were 1.81/100,000 and 0.21/1,000 separations (completed admissions), respectively. Predisposing factors included malignancy (32.1%), indwelling vascular catheters (72.6%), use of antimicrobial agents (77%), and surgery (37.1%). Of 919 episodes, 81.5% were inpatient healthcare associated (IHCA), 11.6% were outpatient healthcare associated (OHCA), and 6.9% were community acquired (CA). Concomitant illnesses and risk factors were similar in IHCA and OHCA candidemia. IHCA candidemia was associated with sepsis at diagnosis (p<0.001), death <30 days after infection (p<0.001), and prolonged hospital admission (p<0.001). Non-Candida albicans species (52.7%) caused 60.5% of cases acquired outside hospitals and 49.9% of IHCA candidemia (p = 0.02). The 30-day death rate was 27.7% in those > or =65 years of age. Adult critical care stay, sepsis syndrome, and corticosteroid therapy were associated with the greatest risk for death. Systematic epidemiologic studies that use standardized definitions for IHCA, OHCA, and CA candidemia are indicated.

RESUMO

Foi realizado um estudo para verificar a ocorrência de leveduras do gênero Rhodotorula, em hemocultura por um período de 8 anos. Os pacientes identificados foram descritos clinicamente segundo variáveis de interesse incluindo dados sobre terapêutica e desfecho. Determinou-se também as concentrações inibitórias mínimas de 20 cepas frente a diferentes antifúngicos de acordo com NCCLS e EUCAST. Realizou-se tipagem molecular através da cariotipagem eletroforética em campo pulsátil.


A study was conducted to verify the frequency of occurrence of Rhodotorula spp. from blood cultures over an 8-year period, clinically and microbiologically characterizing patients affected, including data regarding antifungal treatment and outcome. The minimal inhibitory concentrations of antifungal agents were determined against 20 isolates. Molecular typing of the strains were performed using pulsed field gel electrophoresis method.

RESUMO

BACKGROUND: The efficacy and feasibility of donor granulocyte transfusion therapy (GTX) have changed considerably over the past four decades. The authors sought to determine the impact of high-dose (approximately 5.5 x 10(10) cells) GTX in patients with candidemia. METHODS: The authors' case-control retrospective analysis comprised 491 consecutive patients treated at The University of Texas M. D. Anderson Cancer Center (Houston,TX) from 1993 to 2000. The cohort included 29 patients with Candida species bloodstream infection who had received GTX and 462 who had not. RESULTS: Both groups were comparable in age, gender, APACHE II score, recent chemotherapy received, broad-spectrum antibiotics, systemic corticosteroids, radiotherapy, intravascular catheter, and concordant antifungal therapy (P > or = 0.1). The patients who received GTX compared with those who did not had a higher incidence of underlying leukemia (86% vs. 29%, P <0.001), persistent neutropenia (59% vs. 18%, P <0.001), non-Candida albicans candidemia (Candida glabrata, 35%; Candida krusei, 31%: 90% vs. 67%, P=0.01), and breakthrough invasive mycosis (62% vs. 23%, P <0.001). Neutropenia was more prolonged in patients who received GTX (28 vs. 10 days, P <0.001). Also, more of the patients who received GTX had received hematopoietic stem cell transplantations (28% vs. 13%, P = 0.03), exposure (within 4 weeks) to antifungals (79% vs. 38%, P <0.001), and stays in critical care units (62% vs. 40%, P=0.02). The overall attributable mortality rate for 25 evaluable recipients of GTX was 48% (n=12), compared with 45% (n=115) of 254 evaluable patients in the control group (P=0.5). Of the 158 patients with leukemia, 25 (16%) had received GTX. In patients with leukemia, more of those who had received GTX experienced disseminated candidiasis (44% vs. 26%; P <0.07) and persistent neutropenia (68% vs. 43%, P <0.02), had candidemia that was more prolonged (> 72 hours, P <0.02), and had more stays in critical care units (68% vs. 44%, P <0.03). On the bases of a reduced multivariate model, a significantly increased risk of death was found for patients with hematopoietic stem cell transplantation (odds ratio [OR]=2.51; 95% confidence interval [95% CI], 0.99-6.31; P <0.05), for patients with persistent neutropenia (OR=4.57; 95% CI, 1.99-10.47; P <0.0003), and for patients with leukemia who also had prolonged candidemia (OR=3.59; 95% CI, 1.61-7.98; P <0.002), disseminated candidiasis (OR=5.19; 95% CI, 2.17-12.42; P <0.0002), or non-C. albicans candidemia (OR=5.02; 95% CI, 1.07-23.64; P <0.04). In patients with leukemia, death was attributable to candidemia in 50% of the GTX recipients, compared with 59% of the non-GTX patients who had received antifungal therapy alone (P=0.4). CONCLUSIONS: Despite the presence of multiple predictors of increased mortality, high-dose GTX therapy in these high-risk patients with cancer was associated with better than expected survival rates.
