Investigational non-antibiotic therapeutics for infections in hematopoietic cell transplant recipients and patients with hematologic malignancies receiving cellular therapies. Transpl Infect Dis 2023; 25 Suppl 1:e14193. [PMID: 37957893 DOI: 10.1111/tid.14193] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2023] [Revised: 10/14/2023] [Accepted: 10/30/2023] [Indexed: 11/15/2023]
Abstract
In the age of progressive antimicrobial resistance and increased difficulty combating infections in immunocompromised hosts, there has been renewed interest in the use of nontraditional therapeutics for infections. Herein, we review the use of investigational non-pharmaceutical anti-infective agents targeting fungal, bacterial, and viral infections in patients with hematologic malignancies, focusing on those receiving hematopoietic cell transplantation or cellular therapies. We discuss immune checkpoint inhibitors, granulocyte transfusions, bone marrow colony-stimulating factors, bacteriophages, fecal microbiota transplantation, and virus specific T-cell therapy. Although there is promising early experience with many of these treatments, further studies will be required to define their optimal role in the therapeutic armamentarium against infections in immunocompromised hosts.

Abstract
OBJECTIVES Patients with hematological malignancies have dynamic changes in oral microbial communities before and after treatment. This narrative review describes the changes in oral microbial composition and diversity, and discusses an oral microbe-oriented strategy for oral disease management. MATERIALS AND METHODS A literature search was performed in PubMed/Medline, Web of Science, and Embase for articles published between 1980 and 2022. Any articles on the changes in oral microbial communities in patients with hematological malignancies and their effects on disease progression and prognosis were included. RESULTS Oral sample detection and oral microbial sequencing analysis of patients with hematological malignancies showed a correlation between changes in oral microbial composition and diversity and disease progression and prognosis. The possible pathogenic mechanism of oral microbial disorders is the impairment of mucosal barrier function and microbial translocation. Probiotic strategies, antibiotic strategies, and professional oral care strategies targeting the oral microbiota can effectively reduce the risk of oral complications and the grade of severity in patients with hematological malignancies. CLINICAL RELEVANCE This review provides dentists and hematologists with a comprehensive understanding of the host-microbe associated with hematologic malignancies and oral disease management advice.

[PMID: 36651731 PMCID: PMC9979620 DOI: 10.1128/mbio.03055-22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2022] [Accepted: 12/20/2022] [Indexed: 01/19/2023] Open
Abstract
Serious infections are characterized by rapid progression, poor prognosis, and difficulty in diagnosis. Recently, a new technique known as nanopore-targeted sequencing (NTS) was developed that facilitates the rapid and accurate detection of pathogenic microorganisms and is extremely suitable for patients with serious infections. The aim of our study was to evaluate the clinical application of NTS in the diagnosis and treatment of patients with serious infections. We developed an NTS technology that could detect microorganisms within a 6-h window based on the amplification of the 16S rRNA gene of bacteria, the internal transcribed spacer region of fungi, and the rpoB gene of Mycobacterium. The NTS detection results were compared with those of blood cultures and anal swabs from 50 patients with blood diseases suffering serious infections. The patient's condition before and after NTS was compared. The response rate and the infection-related mortality after the adjustment of antibiotics based on NTS were calculated. The positivity rate of pathogens was highest in NTS (90%), followed by blood culture (32.6%) and anal swabs (14.6%). After adjusting antibiotics for bacteria and fungi detected by NTS, the patients' condition improved significantly. Moreover, the response rate of anti-infective treatment based on NTS was 93.02% (40/43), and infection-related mortality was reduced to 0. NTS is an effective method to identify pathogens in the blood specimens of patients with serious infections and can guide anti-infection treatment and reduce infection-related mortality. IMPORTANCE We introduce the application of NTS in blood samples of patients with serious infections and expound the efficiency and accuracy of NTS in detecting pathogenic microorganisms. Our work builds on the considerable interest of the scientific community in the management of serious infection. This issue is becoming more pressing, especially since the incidence of blood diseases is increasing year by year and hematopoietic stem cell transplantation (HSCT) has been widely used in benign and malignant blood diseases in recent years. The infection progression of these patients is faster, and the study further demonstrates the effectiveness of NTS in guiding the diagnosis and treatment of patients with severe infections. We firmly believe that this method will guide clinicians to adjust anti-infection strategies and bring significant benefits to patients, and our study will have implications for the future clinical application of NTS in all kinds of patients with serious infections.

Abstract
Objective To evaluate whether rates of healthcare-associated infections (HAIs) changed during the coronavirus disease 2019 (COVID-19) pandemic in malignant hematology and stem cell transplant patients. Design A retrospective, cohort study. Patients The study included malignant hematology and stem cell transplant patients admitted between March 1, 2019, through July 31, 2019, and March 1, 2020, through July 31, 2020. Methods Rates of catheter-associated urinary tract infections (CAUTIs), central-line-associated bloodstream infections (CLABSIs), central-line-associated mucosal barrier injury infections (CLAMBIs), and Clostridioides difficile infections (CDIs) during the pandemic were compared to those in a control cohort. Secondary outcomes included the rate of non-COVID-19 respiratory viruses. Results The rate of CAUTIs per 1,000 hospital days was 0.435 before the pandemic and 0.532 during the pandemic (incidence rate ratio [IRR], 1.224; 95% confidence interval [CI], 0.0314-47.72; P = .899). The rate of CLABSIs was 0.435 before the pandemic and 1.064 during the pandemic (IRR, 2.447; 95% CI, 0.186-72.18; P = .516). The rate of CLAMBIs was 2.61 before the pandemic and 1.064 during the pandemic (IRR 0.408, 95% CI 0.057-1.927; P = .284). The rate of CDIs was 2.61 before the pandemic and 1.579 during the pandemic (IRR, 0.612; 95% CI, 0.125-2.457; P = .512). Non-COVID-19 respiratory virus cases decreased significantly from 12 (30.8%) to 2 cases (8.3%) (P = 0.014). Conclusions There was no significant difference in HAIs among inpatient malignant hematology and stem cell transplant patients during the COVID-19 pandemic compared to those of a control cohort. Rates of infection were low among both cohorts. Rates of community-acquired respiratory viruses decreased significantly during the pandemic among this population.

Abstract
Background This study assessed pharmacoeconomic costs associated with extracorporeal photopheresis (ECP) compared with other available second‐line therapies for chronic graft‐vs‐host disease (cGvHD) in a tertiary Spanish institution. Methods Patients (≥18 years) diagnosed with steroid‐refractory cGvHD were eligible. Data were collected retrospectively from index date until 1 year or relapse. Patients were distributed in two cohorts (ECP vs non‐ECP), matched by age (≤ or > 40), hematopoietic stem cell transplant (HLA‐identical sibling donor or other) and number of previous immunosuppressive lines (1, 2, or ≥ 3). Costs were assigned using the 2016 diagnosis‐related group (DRG) system: DRG 579 (€22 383) overnight stay due to major complication (ie, sepsis, pneumonia, parenteral nutrition, or respiratory failure), and DRG 875 (€5154) if no major complication. The primary endpoint was healthcare resource utilization per patient. Results Forty patients (n = 20 per cohort) were included. Median age was 49, and 37.5% were female. Mean total cost per patient was €25 319 (95% CI: €17 049–€33 590) across the two cohorts, with a slightly lower mean cost per ECP‐treated patient (€23 120) compared with the non‐ECP cohort (€27 519; P = .597). Twenty‐seven inpatient hospitalizations occurred among ECP‐treated patients, vs 33 in the non‐ECP cohort. Day hospital and external consultations were more frequent in the ECP cohort. However, fewer inpatient admissions included DRG 579 compared with the non‐ECP cohort (44% vs 58%). Inpatient length of stay was slightly shorter in the ECP cohort (30 vs 49 days; P = .298). Conclusions ECP treatment may yield economic savings in Spain through resource savings and moving costs toward outpatient care.

Epidemiological surveillance of health care-associated infections in a pediatric hematopoietic stem cell transplantation unit in South Brazil. Transpl Infect Dis 2020; 23:e13532. [PMID: 33249699 DOI: 10.1111/tid.13532] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2020] [Revised: 10/19/2020] [Accepted: 11/15/2020] [Indexed: 11/30/2022]
Abstract
BACKGROUND Pediatric hematopoietic stem cell transplantation (HSCT) recipients represent a vulnerable population with regard to health care-associated infections (HAI) with a differentiated profile of etiologic agents.1,2 There are few reports in the literature regarding HAI in the pediatric population submitted to HSCT. METHODS This is a retrospective study conducted in a pediatric HSCT unit in Curitiba, Brazil between February 2013 and December 2017 that evaluated 109 pediatric patients. The variables analyzed were: age, gender, baseline disease, type of transplantation, infection topography, etiologic agent, time of HAI occurrence, antimicrobial prophylaxis, period of neutropenia, length of stay, and outcomes RESULTS: Of 113 HSCT procedures, 91 (83.5%) were allogenic and 18 were autologous (16.5%). The mean age of the patients was 7.9 years, with a median of 8.1 years (4.0 months-17.3 years); 71 (65.1%) were male; 55 (50.5%) presented with an oncologic diagnosis, 32 (29.4%) with a hematological diagnosis, 17 (15.6%) with immunodeficiencies, and 5 (4.6%) with other causes. During hospitalization after HSCT, 86 episodes of HAI were detected in 66 patients, with an infection density of 16.5 infections/1000 patient days, 86% of which occurred after allogeneic transplants, appearing, on average, 15.3 days after transplantation. The main topographies were bloodstream infection (BSI), with 24 (27.9%) cases, and central line-associated bloodstream infection (CLABSI), with 11 (12.8%). Gram-positive bacteria predominated in cultures and HAI was more frequent in patients diagnosed with immunodeficiencies and other non-oncologic and non-hematologic conditions. Among the Gram-positive bacteria, Staphylococcus epidermidis was the main agent identified (77.7%), possibly because of colonization. However, Gram-negative bacteria, with a resistance profile, comprised 40% of the cases of bacterial infections, most of them represented by Klebsiella pneumoniae (66.6%). Of the 66 patients who presented HAI, 59 patients (89.4%) were discharged, and 7 (10.6%) died. CONCLUSION The main topographies were CLABSI and BSI. Patients with immunodeficiencies presented a higher risk for HAI Staphylococcus epidermidis was the main agent identified. However, Klebsiella pneumoniae posed a higher risk for Pediatric Intensive Care Unit admission and death.

Abstract
Prophylaxis with fluoroquinolone (FQ) for patients undergoing autologous stem cell transplantation (ASCT) remains controversial. We performed a retrospective review of patients undergoing ASCT with and without bacterial prophylaxis to compare endpoints of interest. In accordance with institutional policy, patients undergoing ASCT for multiple myeloma routinely receive levofloxacin prophylaxis during their period of neutropenia, whereas patients undergoing the ASCT for lymphoma do not. We retrospectively examined patients with multiple myeloma (MM) or lymphoma undergoing ASCT between July 2015 and July 2018 for evidence of positive blood cultures. A total of 172 patients underwent ASCT for lymphoma and 343 underwent ASCT for MM. The 2 cohorts were similar in terms of baseline characteristics. Almost 20% (35 of 172) of the patients with lymphoma and 5.2% (18 of 342) of those with MM had a bloodstream infection (BSI). BSI occurred an average of 2 days earlier in patients with lymphoma compared with patients with MM (day +5 versus day +7; P = .0003). The 2 cohorts recovered absolute neutrophil count at the same time. Hospital length of stay was 2 days shorter for patients with MM (median, 20 days versus 18 days; P = .01). The majority of the organisms were gram-negative in both cohorts. Of the organisms commonly tested for FQ sensitivity, only 1 of 25 was resistant in the lymphoma cohort, compared with 7 of 9 in the MM cohort (P < .0001), with 4 being multidrug resistant. The odds of developing a BSI were 4.6 times greater in the lymphoma cohort compared with the MM cohort (95% confidence interval [CI], 2.52 to 8.40; P < .0001). In total, 23 of 172 patients with lymphoma (13.4%) and 28 of 342 patients with MM (8.2%) developed Clostridium difficile infection (odds ratio, 1.73; 95% CI, .96 to 3.11; P = .066). Two infection-related deaths occurred in the MM cohort. Our data indicate that FQ prophylaxis reduces the risk of BSI in patients undergoing ASCT but increases the incidence of resistant organisms. We recommend routine antimicrobial prophylaxis in patients undergoing ASCT to reduce the risk of BSI, along with a systematic and regular review of outcomes.

A Novel Severity Score Index for Febrile Neutropenic Patients with Colorectal Diseases. Gastroenterol Res Pract 2019; 2019:4175960. [PMID: 31019530 PMCID: PMC6451812 DOI: 10.1155/2019/4175960] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/31/2018] [Accepted: 02/15/2019] [Indexed: 01/03/2023] Open
Abstract
Introduction Abdominal and anorectal disorders may be the cause of clinical decompensation in neutropenic febrile patients, particularly those with hematologic diseases. Infection is a cause for concern for the colorectal surgeon. Some conditions have few manifestations and can lead to death within a short period of time. This study presents the novel colorectal disorder severity score for febrile neutropenic patients. Materials and Methods This was a case series study analyzing the medical records of 897 patients admitted to the Hematology and Hematopoietic Stem Cell Transplant Unit in a university hospital between the years 2008 and 2013. Seventy-four episodes of febrile neutropenia in 69 patients diagnosed with an abdominal or anorectal infection site were eligible for the study. The new scoring system proposed here is based on the author's clinical experience and an extensive literature review. In addition to the extensive literature review, effect measures were calculated, and a statistical analysis was performed. Based on an evaluation of common biological plausibility criteria, five factors were selected as the main predictors of hospital mortality in febrile neutropenic patients with colorectal disease. Results The proposed score demonstrated increased mortality as the condition worsened as reflected by an increasing score (Fisher's exact test: 0.001). When considering the logistic model for the probability of death by score level, the AUC value was 0.82 (0.72-0.925), and the Hosmer-Lemeshow statistic value was 2.3, p = 0.806. Conclusion The proposed scoring system allows prediction of the likelihood of death during hospitalization for febrile neutropenic patients with an abdominal and anorectal focus. New studies on the subject are required, and the proposed scoring scale must be validated on a larger and different sample of patients.

Abstract
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.

The burden of Invasive Aspergillosis in patients with haematological malignancy: A meta-analysis and systematic review. J Infect 2018; 76:550-562. [PMID: 29727605 DOI: 10.1016/j.jinf.2018.02.012] [Citation(s) in RCA: 36] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2017] [Revised: 02/13/2018] [Accepted: 02/16/2018] [Indexed: 12/14/2022]
Abstract
INTRODUCTION Successful treatment of haematological malignancies is frequently complicated by Invasive Aspergillosis (IA), a life-threatening fungal infection that occurs in at least 10% of haemato-oncological patients. Case fatality rates (CFR) may fluctuate over time, depending on host pathogen interactions as well as on treatment and quality of patient care. We conducted a systematic review and metaanalysis of current - i.e. 2008-revised EORTC-MSG criteria era - incidence and case fatality rates (CFR) of IA in patients with haematological malignancy. METHODS A systematic search according to PRISMA guidelines was performed to identify all literature reporting populations with a haematological malignancy and the incidence of IA, defined according to the EORTC/MSG 2008 criteria. Pooled cumulative incidences and CFR within 100 days were estimated using a random effects model for predefined patient populations and stratified by use of prophylaxis. RESULTS The systematic literature search yielded 1285 publications of which n = 49 met the inclusion criteria. Overall, 16.815 patients were involved of which 1056 (6.3%) developed IA. IA risk ranged from 4% (during remission-induction, with prophylaxis) to 11% (during remission-induction, without prophylaxis). Antifungal prophylaxis was associated with a lower rate of IA, especially in the pre-HSCT population. The pooled CFR within 100 days was 29% (95% CI: 20-38%). DISCUSSION This study confirms that IA is a relevant threat in the treatment of haematological cancer despite the universal use of antifungal prophylaxis. These outcomes inform scientists and other stakeholders about the current burden of IA and may be used to direct, implement and improve antifungal stewardship programs.

Abstract
BACKGROUND Hematopoietic stem cell transplantation (HSCT) consists of the intravenous infusion of healthy hematopoietic stem cells to restore the medullary and immunologic function of patients affected by a series of hematologic, oncologic, immunologic, malignant and nonmalignant inherited or acquired diseases, with the possibility of cure or increase of disease-free survival. OBJECTIVE To characterize the epidemiologic profile and the cases of death of patients who underwent HSCT. METHODS This is a cohort quantitative study, nested with a retrospective, descriptive, and analytical study of a hospital-based cohort that included the patients who underwent HSCT at a referral service in the state of Rio Grande do Norte, a region of northeastern Brazil. RESULTS There was a slight male prevalence (52.94%), the age of the patients ranged from 2 to 73 years old, 18.38% were brown, 47.06% were married, 15.07% were students, 78.31% had a diagnosis of multiple myeloma, 93.38% developed gastrointestinal toxicities, all patients received chemotherapeutic treatment, 54.78% had allogeneic HSCT, and the cause of the most recorded deaths was septic shock (48.19%). CONCLUSIONS This study showed relevant scientific evidence on the clinical and epidemiologic profile of patients who underwent HSCT. In general, sociodemographic data are similar to national and international research results.

Abstract
BACKGROUND Hematopoietic stem cell transplantation (HSCT) has been used as treatment in different hematologic and solid malignancies. The aim of this study was to describe the frequency of infectious complications, microbiology, and outcome in patients undergoing HSCT in Mexico during the pre-engraftment period and the impact on mortality rates at 12 months. METHODS We conducted a retrospective study of all hematologic malignancies that received HSCT from January 2009 and December 2014, at an oncology reference center. RESULTS We included 210 patients: 144 autologous (69%) and 66 allogeneic HSCT (31%). There were 184 infections documented in 109 patients; incidence rate was 47.2 per 1000 neutropenia/days and 22.4 per 1000 hospitalization/days. The main infections reported were pneumonia (n = 40, 19%), bloodstream infections (n = 36, 17.1%), and central line-associated bloodstream infections (n = 28, 13.3%). There were 110 bacteria isolated, 31 were multidrug-resistant (26 were extended-spectrum beta-lactamase; Escherichia coli). There were 25 disseminated or complicated viral infections and 20 invasive fungal diseases. Fourteen patients died in the first 30 days (all related to the infectious process). In multivariate analysis leukemia, more than 2 chemotherapy regimens before transplant and pneumonia were related to 12-month mortality rates. CONCLUSIONS Even though infectious processes are frequent in patients with HSCT, multidrug-resistant bacteria were not as frequent as supposed; however, when these microorganisms are involved, mortality rate is increased. It is important to be alert that patients with pneumonia have a significantly increased mortality risk in the first year.

Abstract
Infections are important complications associated with allogeneic HSCT. Describing infection rates in low- and middle-income countries provides data to infer efficacy of supportive care practices in these settings. In this retrospective cohort study, we included patients (age ≤ 18 years) who underwent a first allogeneic HSCT for ALL in a single center in Argentina between 1998 and 2016. The primary outcome was sterile site bacterial infection. Secondary outcomes were proven or probable invasive fungal infection, TRM, and infectious deaths. There were 68 allogeneic HSCT recipients with ALL included in this analysis. Overall, 17 (25.0%) experienced at least one sterile site bacterial infection and 10 (14.7%) experienced at least one proven or probable invasive fungal infection. The TRM rate was 19.1%, and 3 (4.4%) patients died of infection. In a middle-income country center in Argentina, pediatric allogeneic HSCT infection rates, TRM, and infection-related mortality were comparable to high-income countries. These data support continuation of allogeneic HSCT programs in similar resource-limited settings provided that adequate supportive care and monitoring of outcomes can be performed.

Abstract
BACKGROUND Infections greatly influence the outcome of acute myeloid leukemia (AML) patients receiving intensive treatment. The aim of this study was to establish the incidence, microbial etiology, risk factors and prognosis of bloodstream infections (BSIs) in patients with AML and compare the results with the previous treatment protocol (AML-92). METHODS Registery data were gathered prospectively from 357 patients aged 16-65 years recruited on the AML-2003 treatment protocol between November 2003 and November 2011 during different treatment cycles. RESULTS Blood culture data were available on 977 treatment episodes, in which there were 503 BSIs (51%). The overall incidence rate (IR) for BSIs (per 1000 hospital days) was 16.7. Twenty patients (5.6%) died due to an infection and 16 of them (80%) had a BSI. The most commonly detected microbes (polymicrobial episodes included) in blood cultures were coagulase-negative staphylococci (CoNS, 24.7%), viridans group streptococci (VGS, 19.1%), enterococci (13.9%) and Enterobacteriacae group (25.9%). The etiology of BSIs varied greatly from treatment cycle to cycle. CONCLUSIONS Enterococcal BSIs have increased compared to our previous treatment protocol, and they represent significant pathogens in blood cultures. Infection-related mortality has decreased despite the increase in the IR of BSIs. Enterococci seem to be an increasingly prominent pathogen underlying BSIs in the AML patients, especially during induction therapy (20%).

Abstract
Background Infection is a major cause of morbidity and mortality after allogeneic hematopoietic cell transplantation (HCT). Our object was to better define the epidemiology and outcomes of infections after HCT. Methods This was a prospective, multicenter cohort study of HCT recipients and conducted from 2006 to 2011. The study included 4 US transplant centers and 444 HCT recipients. Data were prospectively collected for up to 30 months after HCT using a standardized data collection tool. Results The median age was 53 years, and median follow up was 413 (range, 5–980) days. The most common reason for HCT was hematologic malignancy (87%). The overall crude mortality was 52%. Death was due to underlying disease in 44% cases and infection in 21%. Bacteremia occurred in 231 (52%) cases and occurred early posttransplant (median day 48). Gram-negative bloodstream infections were less frequent than Gram-positive, but it was associated with higher mortality (45% vs 13%, P = .02). Clostridium difficile infection developed in 148 patients (33%) at a median of 27 days post-HCT. There were 53 invasive fungal infections (IFIs) among 48 patients (11%). The median time to IFI was 142 days. Of 155 patients with cytomegalovirus (CMV) infection, 4% had CMV organ involvement. Varicella zoster infection (VZV) occurred in 13 (4%) cases and was disseminated in 2. Infection with respiratory viruses was seen in 49 patients. Pneumocystis jirovecii pneumonia was rare (1%), and there were no documented cases of nocardiosis, toxoplasmosis, endemic mycoses, or mycobacterial infection. This study lacked standardized antifungal and antiviral prophylactic strategies. Conclusions Infection remains a significant cause of morbidity and mortality after HCT. Bacteremias and C difficile infection are frequent, particularly in the early posttransplant period. The rate of IFI is approximately 10%. Organ involvement with CMV is infrequent, as are serious infections with VZV and herpes simplex virus, likely reflecting improved prevention strategies.

Abstract
Health care associated infections (HAIs) are currently among the major challenges to the care of hematopoietic stem cell transplantation (HSCT) patients. The objective of the present study was to evaluate the impact of 2% chlorhexidine (CHG) bathing on the incidence of colonization and infection with vancomycin-resistant Enterococcus (VRE), multidrug-resistant (MDR) gram-negative pathogens, and to evaluate their CHG minimum inhibitory concentration (MIC) after the intervention.A quasi-experimental study with duration of 9 years was conducted. VRE colonization and infection, HAI rates, and MDR gram-negative infection were evaluated by interrupted time series analysis. The antibacterial susceptibility profile and mechanism of resistance to CHG were analyzed in both periods by the agar dilution method in the presence or absence of the efflux pump inhibitor carbonyl cyanide-m-chlorophenyl hydrazone (CCCP) and presence of efflux pumps (qacA/E, qacA, qacE, cepA, AdeA, AdeB, and AdeC) by polymerase chain reaction (PCR).The VRE colonization and infection rates were significantly reduced in the postintervention period (P = 0.001). However, gram-negative MDR rates in the unit increased in the last years of the study. The CHG MICs for VRE increased during the period of exposure to the antiseptic. A higher MIC at baseline period was observed in MDR gram-negative strains. The emergence of a monoclonal Pseudomonas aeruginosa clone was observed in the second period.Concluding, CHG bathing was efficient regarding VRE colonization and infection, whereas no similar results were found with MDR gram-negative bacteria.

Abstract
INTRODUCTION Critically ill patients are at high risk of nosocomial infections, with between 20% and 40% of patients admitted to the intensive care unit (ICU) acquiring infections. These infections result in increased antibiotic use, and are associated with morbidity and mortality. Although critical illness is classically associated with hyperinflammation, the high rates of nosocomial infection argue for an importance of effect of impaired immunity. Our group recently demonstrated that a combination of 3 measures of immune cell function (namely neutrophil CD88, monocyte HLA-DR and % regulatory T cells) identified a patient population with a 2.4-5-fold greater risk for susceptibility to nosocomial infections. METHODS AND ANALYSIS This is a prospective, observational study to determine whether previously identified markers of susceptibility to nosocomial infection can be validated in a multicentre population, as well as testing several novel markers which may improve the risk of nosocomial infection prediction. Blood samples from critically ill patients (those admitted to the ICU for at least 48 hours and requiring mechanical ventilation alone or support of 2 or more organ systems) are taken and undergo whole blood staining for a range of immune cell surface markers. These samples undergo analysis on a standardised flow cytometry platform. Patients are followed up to determine whether they develop nosocomial infection. Infections need to meet strict prespecified criteria based on international guidelines; where these criteria are not met, an adjudication panel of experienced intensivists is asked to rule on the presence of infection. Secondary outcomes will be death from severe infection (sepsis) and change in organ failure. ETHICS AND DISSEMINATION Ethical approval including the involvement of adults lacking capacity has been obtained from respective English and Scottish Ethics Committees. Results will be disseminated through presentations at scientific meetings and publications in peer-reviewed journals. TRIAL REGISTRATION NUMBER NCT02186522; Pre-results.

Abstract
Bacteremia is a significant complication of allogeneic hematopoietic stem cell transplantation (HSCT). We aimed to study bacteremia occurring during early post-transplant period at Bone Marrow Transplantation Unit of Ain Shams University regarding its risk factors and impact on survival. Patients performing allogeneic HSCT were followed up for occurrence of bacteremia. Survival status was assessed at 180 days post-transplant. Bacteremia occurred in 53.3 % of patients. On univariate analysis, CD34 +ve cell dose (P = 0.004), duration of neutropenia (P = 0.018), time interval between day of stem cell infusion and day of neutrophil engraftment (P = 0.043) and > 1 apheresis days (P = 0.040) were associated with higher rates of bacteremia. On multivariate analysis, CD34 +ve cell dose (P = 0.002) and apheresis day number (P = 0.038) remained significant. There was significant difference between patients who developed bacteremia and those who did not regarding overall survival (OS) (P = 0.042). Patients developing bacteremia caused by Gram negative bacteria (GNB) had lower OS than Gram positive bacteria (GPB) (P < 0.001). In conclusion, stem cell dose and apheresis day number influence bacteremia risk. Also, Gram negative bacteremia has negative impact on allogeneic transplant recipient survival rates.

[PMID: 27103500 DOI: 10.1016/j.jmii.2016.02.003] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 09/07/2015] [Revised: 12/18/2015] [Accepted: 02/24/2016] [Indexed: 10/22/2022]
Abstract
BACKGROUND The aim of this study was to compare the risk factors and clinical outcomes of bacteremia in allogeneic and autologous hematopoietic stem cell transplant (allo-HSCT and auto-HSCT) recipients with levofloxacin prophylaxis during the early period after transplantation. METHODS Characteristics of bacteremia within 45 days after transplantation between allo-HSCT and auto-HSCT recipients who received levofloxacin prophylaxis between January 2005 and December 2014 were retrospectively reviewed. RESULTS Of 105 HSCT recipients included in this study, 55 (52.4%) received an allo-HSCT and 50 (47.6%) received an auto-HSCT. Twenty-five patients (23.8%) with HSCT developed 28 episodes of bacteremia. Of these 25 bacteremia patients, 15 received an allo-HSCT, while 10 received an auto-HSCT. The occurrence of Grade 3-4 graft-versus-host disease and longer engraftment duration were associated with bacteremia in allo- and auto-HSCT recipients (p = 0.001 and p = 0.002, respectively). Auto-HSCT recipients with bacteremia had a longer hospital stay after transplantation, while allo-HSCT recipients with bacteremia had an increased 45-day mortality rate as compared with those without bacteremia (p = 0.014 and p = 0.013, respectively). All 14 Gram-negative blood isolates in this study were resistant to fluoroquinolone. CONCLUSION Levofloxacin prophylaxis in HSCT recipients is associated with the emergence of fluoroquinolone-resistant Gram-negative bacteria. The risk factors and clinical outcomes of bacteremia differ between allo- and auto-HSCT recipients, and these differences should be taken into account when designing strategies to prevent bacteremia.

Abstract
Objective Conditioning regimens for hematopoietic stem cell transplantation (HSCT) are well known to cause severe gastrointestinal toxicities that often disturb the oral intake of the patients followed by poor nutrition and life-threatening infection. An oral elemental diet (ED) is an easily consumed and assimilated form of liquid nutrients mainly composed of amino acids. It alleviates the digestive loading from the intestine and is mainly used for enteral nutritional support in patients with Crohn's disease. We herein report, for the first time, the efficacy of ED for patients undergoing HSCT. Methods We evaluated the efficacy of ED in a prospective cohort study. The primary endpoint for this study was the hospitalization period. The secondary endpoint was the occurrence of oral mucositis, nausea, diarrhea and fever. Patients A total of 73 patients were consecutively enrolled between March 2011 and March 2013. Twenty-three patients underwent autologous HSCT and 50 patients underwent allogeneic HSCT. The first 21 patients did not receive ED (non-ED group; NEG) while in the successive 52 patients (ED group; EG), oral ED was started before conditioning and was continued until 28 days after transplantation. Results The patient characteristics were similar between the two groups. The mean duration of ED administration for EG was 28.7 days (range, 3-37 days), and the mean total-dose of ED administration was 1904 g (range, 240-2,960 g). The median hospitalization period was significantly shorter in EG compared to NEG, (34 days vs. 50 days; p=0.007). Grade 3-4 oral mucositis occurred less in EG than NEG (25% vs. 48%; p=0.06). Conclusion Oral ED may promote an early mucosal recovery and thereby shorten the duration of hospitalization.

Abstract
The China Assessment of Antifungal Therapy in Hematological Disease study, the first large-scale observational study of invasive fungal disease (IFD) in China, enrolled 1401 patients undergoing hematopoietic stem cell transplantation (HSCT) (75.2% allogeneic and 24.8% autologous) at 31 hospitals across China. The overall incidence of proven or probable IFD was 7.7% (108 of 1401); another 266 cases (19.0%) were possible IFD. After allogeneic or autologous HSCT, the incidence of proven/probable IFD was 8.9% (94 of 1053) and 4.0% (14 of 348), respectively. Some cases (14 of 108) developed during conditioning before transplantation. The cumulative incidence of proven/probable IFD increased steeply in the first month after transplantation and after 6 months, the incidence was significantly higher in allogeneic than it was in autologous transplant recipients (9.2% versus 3.5%; P = .001) and when stem cells were derived from cord blood or bone marrow and peripheral blood (P = .02 versus other sources). Independent risk factors for proven/probable IFD in allogeneic HSCT were diabetes, HLA-matched unrelated donor, prolonged severe neutropenia (absolute neutrophil count > 500/mm(3) for >14 days), and immunosuppressants (odds ratio, 2.0 to 3.4 for all). Antifungal prophylaxis was independently protective (P = .01). Previous IFD and prolonged severe neutropenia were significant independent risk factors among autologous transplantation patients (P < .01, P = .04, respectively). In total, 1175 (83.9%) patients received antifungal prophylaxis (91.6% triazoles) and 514 (36.7%) were treated in the hospital with therapeutic antifungals (89.1% triazoles; median 27 days). Empirical, pre-emptive, and targeted antifungals were used in 82.3%, 13.6%, and 4.1% of cases, respectively. Overall mortality (13.4%; 188 deaths) was markedly higher in patients with proven (5 of 16; 31.3%), probable (20 of 92; 21.7%), or possible (61 of 266; 22.9%) IFD; allogeneic (171 of 1053; 16.2%) rather than autologous (17 of 348; 4.9%) HSCT and was significantly higher in patients receiving pre-emptive (18.6%) rather than empirical (6.1%) or targeted (9.5%) antifungal therapy (P = .002). Improvements in the selection and timing of prophylactic antifungals would be welcome. Health care providers should remain alert to the increased risk of IFD and associated mortality in allogeneic HSCT recipients and the ongoing risk of IFD even after discharge from the hospital.

Abstract
Children undergoing HSCT are at risk for complications due to immune system impairment, toxicity from prior therapies and conditioning regimens, and long-term use of indwelling catheters. These problems may require assessment by the surgical team. We sought to characterize the role of surgical consultation during primary hospital stay for HSCT. We retrospectively reviewed the records of consecutive patients undergoing HSCT between September 2010 and September 2012. One hundred and seventy-three patients underwent 189 HSCTs. General surgery consultations occurred during 33% (n = 62) of primary hospitalizations for HSCT, with a total of 85 consults. Sixty-three (73%) consults resulted in an intervention in the operating room or at the bedside. The majority of consults were for CVL issues (59%, n = 50), followed by abdominal complaints (16%, n = 14). Patients requiring surgical consultation had significantly higher in-hospital mortality (16% vs. 2%, p < 0.01) and 100-day TRM (10% vs. 2%, p < 0.01), compared with those not requiring consultation. Patients undergoing HSCT often require surgical consultation, most commonly for line-related issues. Surgical consultation heralded an increased risk of in-hospital and 100-day TRM. Issues among this high-risk cohort of children who have undergone HSCT must be familiar to the general surgeon and oncologist alike.

Abstract
Background Febrile neutropenia is an important cause of mortality and morbidity in hematology–oncology patients undergoing chemotherapy. The management of febrile neutropenia is typically algorithm-driven. The aim of this study was to assess the results of a standardized protocol for the treatment of febrile neutropenia. Methods A retrospective cohort study (2011–2012) was conducted of patients with high-risk neutropenia in a hematology–oncology service. Results Forty-four episodes of 17 patients with a median age of 48 years (range: 18–78 years) were included. The incidence of febrile neutropenia was 61.4%. The presence of febrile neutropenia was associated with both the duration and severity of neutropenia. Microbiological agents were isolated from different sources in 59.3% of the episodes with bacteremia isolated from blood being the most prevalent (81.3%). Multiple drug-resistant gram-negative bacilli were isolated in 62.5% of all microbiologically documented infections. Treatment of 63% of the episodes in which the initial treatment was piperacillin/tazobactam needed to be escalated to meropenem. The mortality rate due to febrile neutropenia episodes was 18.5%. Conclusion The high rate of gram-negative bacilli resistant to piperacillin/tazobactam (front-line antibiotics in our protocol) and the early need to escalate to carbapenems raises the question as to whether it is necessary to change the current protocol.

Abstract
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.

Abstract
BACKGROUND The morbidity and mortality in hematopoietic stem cell transplantation (HSCT) occur due to infectious complications and constitute the major clinical problems in HSCT recipients. The role of the use of biomarkers in post-HSCT patients is still controversial. OBJECTIVES To assess the serum values of biomarkers interleukin 6 (IL-6), procalcitonin (PCT) and C-reactive protein (CRP) and risk factors for post-HSCT death. PATIENTS AND METHODS Prospective study conducted in patients submitted to HSCT at a university hospital. Biomarkers (IL-6, PCT and CRP) were assessed on the day afebrile neutropenia was detected, in the febrile event, 24 and 72 h after fever onset and 48 h or 5 days if fever persisted. Patients were compared as to the death outcome within 30 days from the HSCT. Variables with p < 0.15 were included in the multivariate analysis model (MVA) that were performed for all patients included in the study and separated for autologous and allogeneic HSCT patients. RESULTS 296 patients with ages ranging between 15 and 70 years, neutropenic, submitted to HSCT, being 216 (73%) autologous and 80 (20%) allogeneic were assessed. One hundred and ninety (64.2%) patients presented fever after the transplantation and infection microbiologically controlled in 78 (26.4%). Twenty-three cases (7.8%) evolved to death. The risk factors associated with death in the bivariate analysis were age, allogeneic transplantation, unrelated transplantation, GVHD, bloodstream infection by Gram-negative, IL-6 >140 pg/mL and CRP ≥ 120 mg/L and the protective ones were lymphoma and hospital outpatient support. The independent variables in the MVA associated with death were allogeneic and unrelated transplantation, blood stream infection (BSI) by Gram-negative, LDH ≥ 390 UI/L, urea ≥ 25 mg/dL and CRP ≥ 120 mg/L for HSCT transplanted patients and BSI due to Gram-negative and CRP ≥ 120 mg/L for allogeneic HSCT, however, CRP ≥ 120 mg/L did not remain in the model when urea ≥ 25 mg/L was included. No independent risk factor was found for autologous patients. CONCLUSIONS Out of the biomarkers assessed, only CRP ≥ 120 mg/L was independently associated with death. Other risk factors found were: type of transplantation (allogeneic and unrelated), bloodstream infection by Gram-negative, LDH ≥ 390 UI/L and urea ≥ 25 mg/dL. For allogeneic patients only CRP ≥ 120 mg/L and BSI due to Gram-negative were risk factors for death; however, CRP did not remain in the model when urea ≥ 25 mg/L was included.

Abstract
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.

Abstract
OBJECTIVES Information on the efficacy of extended meropenem administration in neutropenic patients is scarce. Our objective was to determine whether the administration of meropenem in a 4 h extended infusion (EI) leads to a better clinical outcome in patients with febrile neutropenia than the conventional short infusion (SI). METHODS This was a retrospective observational study. The subjects were neutropenic patients who presented with fever after receiving haematopoietic stem-cell transplantation or induction chemotherapy for acute myeloid leukaemia. The primary endpoint was the success of treatment after 5 days of meropenem therapy, defined as follows: the disappearance of fever leading to a maintained (≥ 24 h) feverless state; the resolution or improvement of the clinical signs and symptoms of infection; the absence of persistent or breakthrough bacteraemia; and no additional antibiotics prescribed because of an unsatisfactory clinical evolution. RESULTS Eighty-eight patients received meropenem (1 g/8 h) in SI and 76 received the same dose in EI. Treatment success on day 5 was superior in the EI group [52/76 (68.4%) versus 36/88 (40.9%); P<0.001]. Meropenem administered in EI was independently associated with success (OR 3.13, 95% CI 1.61-6.10). Fewer additional antibiotics were prescribed in the EI group during the first 5 days of treatment [20/76 (26.3%) versus 44/88 (50.0%); P=0.002]. Using Kaplan-Meier survival analysis a more prompt defervescence and a faster decrease in C-reactive protein concentration were observed in the EI group (P=0.021 and P=0.037, respectively). There were no significant differences in the length of hospital stay and in the mortality rate. CONCLUSIONS Meropenem administration in EI results in a better clinical outcome for febrile neutropenia episodes, with fewer additional antibiotics needed.
