Clinical Characteristics and Epidemiological Analysis of Pneumocystis Jirovecii Pneumonia Infection in Kidney Transplant Patients with Trimethoprim-Sulfamethoxazole Dose Reduction Prophylaxis Strategy. Infect Drug Resist 2024; 17:2299-2306. [PMID: 38868399 PMCID: PMC11168416 DOI: 10.2147/idr.s461206] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2024] [Accepted: 05/21/2024] [Indexed: 06/14/2024] Open
Abstract
Background The administration of trimethoprim-sulfamethoxazole (TMP-SMX) for the prophylaxis of Pneumocystis jirovecii pneumonia (PJP) has proven to be highly efficacious in individuals who have undergone kidney transplantation. Nevertheless, the potential for severe adverse reactions associated with this treatment cannot be overlooked, and the determination of an optimal dosage regimen continues to be a matter of investigation. The current study evaluated the effectiveness of low-dose TMP-SMX for PJP prophylaxis in kidney transplant patients and conducted an analysis of the clinical characteristics and epidemiological trends in patients with PJP infection. Methods This retrospective analysis studied electronic medical records of 1763 kidney transplant recipients from 2017 to 2020. These patients were initially prescribed a daily half-strength TMP-SMX (40 mg/200 mg), and the efficacy of this regimen was assessed during a follow-up period of 3-51 months. Results Under our PJP prevention and adjustment strategy, 24 patients were infected with PJP. The overall morbidity of PJP infection in our study was 1.36%, corroborates with findings from previously published studies. Among these 24 patients, up to 87.5% had their dosage adjusted due to increased creatinine or other adverse reactions, the most frequent dose was daily quarter-strength TMP-SMX (20 mg/100 mg). TMP-SMX prophylaxis successfully postponed and distributed the onset of PJP, with the mean duration from transplantation to the occurrence of PJP being 13.50±7.11 months. Conclusion Daily administration of half-strength TMP-SMX can effectively prevent PJP, and prolonging prophylaxis with this medication may potentially reduce the incidence of infection.

Clinical impact and early prediction of carbapenem-resistant Pseudomonas aeruginosa bacteraemia in allogeneic hematopoietic stem cell transplantation recipients. J Glob Antimicrob Resist 2023; 32:187-194. [PMID: 36806701 DOI: 10.1016/j.jgar.2023.02.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2022] [Revised: 01/29/2023] [Accepted: 02/05/2023] [Indexed: 02/19/2023] Open
Abstract
OBJECTIVE Although antipseudomonal agents are administered in high-risk patients, no reports have focused on the risk of carbapenem-resistant (CR) Pseudomonas aeruginosa bacteraemia in allogeneic hematopoietic stem cell transplantation (allo-HSCT) recipients. METHODS We retrospectively studied a cohort of adult allo-HSCT recipients with P. aeruginosa bacteraemia, focusing on a comparison between carbapenem-sensitive (CS) and CR P. aeruginosa after initiating conditioning chemotherapy at our institute between January 2005 and December 2020. The incidence, all-cause 30-d mortality of P. aeruginosa bacteraemia, and risk factors for carbapenem resistance among patients with P. aeruginosa bacteraemia in allo-HSCT recipients were evaluated. RESULTS Forty-eight patients with P. aeruginosa bacteraemia were included, with an incidence of 3.84/100 recipients (CS = 1.92 vs. CR = 1.92). The all-cause 30-d mortality was significantly higher in CR P. aeruginosa bacteraemia (CS = 4.2% vs. CR = 39.1%; P = 0.003). The factor significantly associated with CR P. aeruginosa bacteraemia was carbapenem use for at least 3 d within 30 d before the onset of bacteraemia (odds ratio = 8.92; 95% confidence interval: 1.35-58.90). Inappropriate antimicrobial selection was significantly more frequent in CR P. aeruginosa bacteraemia (CS = 0% vs. CR = 29.2%; P ˂ 0.009). CONCLUSION Empirical combination therapy with reference to antimicrobial susceptibility profiles in each institution should be considered when CR P. aeruginosa bacteraemia is suspected in allo-HSCT recipients based on the risk of carbapenem exposure.

Stenotrophomonas maltophilia bloodstream infections in adult recipients of umbilical cord blood transplantation. Transplant Cell Ther 2020; 27:269.e1-269.e7.

Abstract
Limited data are available on Stenotrophomonas maltophilia bloodstream infections (SM-BSIs) and the therapeutic efficacy of trimethoprim-sulfamethoxazole (SXT) against SM-BSI in umbilical cord blood transplant (uCBT) recipients. Medical and microbiological records of adult patients who received uCBTs between December 2008 and December 2015 at Toranomon Hospital (Tokyo, Japan) were reviewed. The efficacy and safety of SXT were evaluated only for recipients who were treated with ≥7 days of intravenous SXT for SM-BSI (evaluation cohort). Of 561 uCBT recipients, 34 developed SM-BSI. Diabetes mellitus (P = .005) and age ≥ 60 years (P = .013) were significant independent risk factors for SM-BSI. Moreover, SM-BSI was identified as an independent risk factor for all-cause mortality up to 100 days following uCBT (P = .025). Of the 34 recipients with SM-BSI, 24 were treated with an intravenous SXT-containing regimen (iSXT-CR). Septic shock (P = .0021), pneumonia (P = .011), neutropenia (P = .0015), and systemic steroid administration (P = .018) were identified as significant independent risk factors for 7-day crude mortality. The evaluation cohort included nine recipients. Doses of SXT were 2.4 to 6.9 mg/kg/day of the trimethoprim component. Of the nine recipients, five developed SM-BSI during the pre-engraftment phase. The 30-day crude-mortality rate and clinical cure rate of the cohort were 22% and 67%, respectively. Only one of the nine recipients experienced significant neutrophil toxicity. In this study, the epidemiology of SM-BSI in uCBT recipients was determined and its negative impact on survival was demonstrated. A low- to moderate-dose iSXT-CR appeared to be a tolerable and important therapeutic option for SM-BSI in the uCBT setting, including during the pre-engraftment phase.

Abstract
Hematopoietic stem cell transplant recipients are at increased risk of infection and immune dysregulation due to reception of cytotoxic chemotherapy; development of graft versus host disease, which necessitates treatment with immunosuppressive medications; and placement of invasive catheters. The prevention and management of infections in these vulnerable hosts is of utmost importance and a key “safety net” in stem cell transplantation. In this review, we provide updates on the prevention and management of CMV infection; invasive fungal infections; bacterial infections; Clostridium difficile infection; and EBV, HHV-6, adenovirus and BK infections. We discuss novel drugs, such as letermovir, isavuconazole, meropenem-vaborbactam and bezlotoxumab; weigh the pros and cons of using fluoroquinolone prophylaxis during neutropenia after stem cell transplantation; and provide updates on important viral infections after hematopoietic stem cell transplant (HSCT). Optimizing the prevention and management of infectious diseases by using the best available evidence will contribute to better outcomes for stem cell transplant recipients, and provide the best possible “safety net” for these immunocompromised hosts.

Safety and efficacy of prophylaxis for Pneumocystis jirovecii pneumonia involving trimethoprim-sulfamethoxazole dose reduction in kidney transplantation. BMC Infect Dis 2019; 19:311. [PMID: 30953458 PMCID: PMC6451305 DOI: 10.1186/s12879-019-3944-0] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2018] [Accepted: 03/29/2019] [Indexed: 11/15/2022] Open
Abstract
Background Trimethoprim-sulfamethoxazole (TMP-SMX) is the drug of choice for anti-Pneumocystis jirovecii pneumonia (PcP) prophylaxis in kidney transplant recipients (KTR). Post-transplant management balances preventing PcP with managing TMP-SMX-related adverse effects. TMP-SMX dose reduction addresses adverse effects but its implications to incident PcP are unclear. Methods We performed a retrospective review of all patients transplanted between 2011 and 2015 prescribed daily single strength TMP-SMX for twelve months post-transplantation as PcP prophylaxis. Actual TMP-SMX dose and duration, adverse effects, number of dose reductions and reasons, and PcP events were captured. Multivariate logistic regression analyses for risk factors associated with dose reduction were performed. Results Of 438 KTR, 233 (53%) maintained daily TMP-SMX and 205 (47%) sustained ≥1 dose reduction, with the point prevalence of a reduced dose regimen being between 18 and 25%. Median duration for daily TMP-SMX was 8.45/12 months, contributing 4137 patient-months daily TMP-SMX and 1110 patient-months with a reduced dose. PcP did not occur in any patients. There were 84 documented dose reductions for hyperkalemia and 102 for leukopenia, with 12 and 7 patients requiring TMP-SMX cessation. In multivariate analysis, a living donor transplant protected against hyperkalemia (Odds Ratio 0.46, 95% CI 0.26–0.83, p < 0.01) while acute rejection risked leukopenia (Odds Ratio 3.31, 95% CI 1.39–7.90, p = 0.006). Conclusions TMP-SMX dose reduction is frequent in the first post-transplant year but PcP does not occur. To limit the need for TMP-SMX dose reduction due to adverse effects, a clinical trial comparing daily to thrice weekly single strength TMP-SMX in de-novo KTR is justified.

Abstract
PURPOSE OF REVIEW The use of prophylactic antibiotics during the neutropenic period in hematopoietic stem cell transplantation has been the standard of care at most institutions for the past 20 years. We sought to review the benefits and risks of this practice. RECENT FINDINGS Emerging data has highlighted the potential costs of antibacterial prophylaxis, from selecting for antibiotic resistance to perturbing the microbiome and contributing to increase risk for Clostridium difficile and perhaps graft-versus-host-disease, conditions which may lead to poorer outcomes. Though in many studies prophylactic antibiotics improved morbidity and mortality outcomes, the potential harms including antibiotic resistance, Clostridium difficile infection, and alterations of the gut microbiome should be considered. Future studies aimed to better risk-stratify patients and limit the use of broad-spectrum antibiotics are warranted.

Abstract
Increasingly, the risk of a radiological or nuclear public health emergency is a major concern for the U.S. government. To address a potential incident and ensure that the U.S. Government is prepared to respond to any civilian or military casualties that could result, the U.S. Department of Health and Human Services (HHS), together with the Department of Defense, has been charged with the development of medical countermeasures (MCMs) to treat individuals experiencing acute and delayed injuries that can result from exposure to radiation. With limited research and development budgets, and the high costs associated with bringing promising approaches from the bench through advanced product development activities, and ultimately, to regulatory approval, the U.S. Government places a priority on repurposing drugs that have already been commercialized for other indications in humans. To address the benefits and challenges of repurposing licensed products for a radiation indication, the National Institute of Allergy and Infectious Diseases convened a workshop with participants from U.S. Government agencies and industry, as well as academic subject matter experts. Topics included U.S. Government efforts (e.g., funding, regulatory, stockpiling and innovative ways to make drugs available for study), as well as the unique regulatory and other challenges faced when repurposing branded or generic drugs.

Abstract
The risk of a radiological or nuclear public health emergency is a major growing concern of the U.S. government. To address a potential incident and ensure that the government is prepared to respond to any subsequent civilian or military casualties, the U.S. Department of Health and Human Services and the Department of Defense have been charged with the development of medical countermeasures (MCMs) to treat the acute and delayed injuries that can result from radiation exposure. Because of the limited budgets in research and development and the high costs associated with bring promising approaches from the bench through advanced product development activities, and ultimately, to regulatory approval, the U.S. government places a priority on repurposing products for which there already exists relevant safety and other important information concerning their use in humans. Generating human data can be a costly and time-consuming process; therefore, the U.S. government has interest in drugs for which such relevant information has been established (e.g., products for another indication), and in determining if they could be repurposed for use as MCMs to treat radiation injuries as well as chemical and biological insults. To explore these possibilities, the National Institute of Allergy and Infectious Diseases (NIAID) convened a workshop including U.S. government, industry and academic subject matter experts, to discuss the challenges and benefits of repurposing products for a radiation indication. Topics covered included a discussion of U.S. government efforts (e.g. funding, stockpiling and making products available for study), as well unique regulatory and other challenges faced when repurposing patent protected or generic drugs. Other discussions involved lessons learned from industry on repurposing pre-license, pipeline products within drug development portfolios. This report reviews the information presented, as well as an overview of discussions from the meeting.

Abstract
OBJECTIVES Clostridium difficile infection (CDI) is the most common cause of healthcare-associated infections in the United States. Despite well-established risk factors, little research has focused on use of these variables to identify a patient population at high risk for CDI to target with primary prevention strategies. A predictive index for healthcare-associated CDI could improve clinical care and guide research for primary prevention trials. Our objective was to develop a predictive index to identify patients at high risk for healthcare-associated CDI. METHODS We performed a secondary database analysis in a five-hospital health system in Houston, Texas. Our cohort consisted of 97 130 hospitalized patients admitted for more than 48 hours between October 2014 and September 2016. The derivation cohort consisted of the initial 80% of admissions (75 545 patients), with the remainder being used in the validation cohort. RESULTS CDI rates in the derivation and validation cohorts were 1.55% and 1.43%, respectively. Thirty-day predictors of CDI were increased number of high-risk antibiotics, Charlson comorbidity index score, age and receipt of a proton pump inhibitor. These variables were incorporated into a simple risk index with a score range of 0 to 10. The final model demonstrated good discrimination and calibration with the observed CDI incidence ranging from 0.1% to 20.4%. CONCLUSIONS We developed a predictive index for 30-day risk of healthcare-associated CDI using readily available and clinically useful variables. This simple predictive risk index may be used to improve clinical decision making and resource allocation for CDI stewardship initiatives, and guide research design.

Abstract
Toxoplasmosis (TXP) is a life-threatening complication of allogeneic haematopoietic stem cell transplantation (AHSCT). Little is known about the risk factors and there is no consensus on prophylactic measures. To investigate the risk factors, we conducted a single-centre, retrospective matched case-control study among adults who underwent AHSCT from January 2006 to March 2015 in our hospital. TXP cases were identified from the prospectively maintained hospital's database. The 1:2 control population consisted of the two patients who received an AHSCT immediately before and after each case with similar donor relationship (related, unrelated) but who did not develop TXP. Risk factors were identified by conditional logistic regression. Clinical features and outcome of TXP were examined. Twenty-three (3.9%) cases of TXP (20 diseases, three infections) were identified among 588 AHSCT recipients. Twenty (87%) cases had a positive pre-transplant Toxoplasma gondii serology. In comparison with 46 matched control patients, risk factors were the absence of effective anti-Toxoplasma prophylaxis (odds ratio (OR) 11.95; 95% CI 3.04-46.88; p <0.001), high-grade (III-IV) acute graft-versus-host-disease (OR 3.1; 95% CI 1.04-9.23; p 0.042) and receipt of the tumour necrosis factor-α blocker etanercept (OR 12.02; 95% CI 1.33-108.6; p 0.027). Mortality attributable to TXP was 43.5% (n = 10). Non-relapse mortality rates during the study period of cases and controls were 69.6% (n = 16) and 17.4% (n = 8), respectively. Lung involvement was the dominant clinical feature (n = 14). Two cases were associated with graft failure, one preceded by haemophagocytic syndrome. Given TXP-related morbidity and attributable mortality, anti-Toxoplasma prophylaxis is essential for optimized management of seropositive AHSCT recipients.

Abstract
BACKGROUND Febrile neutropenia (FN) and other infectious complications are some of the most serious treatment-related toxicities of chemotherapy for cancer, with a mortality rate of 2% to 21%. The two main types of prophylactic regimens are granulocyte (macrophage) colony-stimulating factors (G(M)-CSF) and antibiotics, frequently quinolones or cotrimoxazole. Current guidelines recommend the use of colony-stimulating factors when the risk of febrile neutropenia is above 20%, but they do not mention the use of antibiotics. However, both regimens have been shown to reduce the incidence of infections. Since no systematic review has compared the two regimens, a systematic review was undertaken. OBJECTIVES To compare the efficacy and safety of G(M)-CSF compared to antibiotics in cancer patients receiving myelotoxic chemotherapy. SEARCH METHODS We searched The Cochrane Library, MEDLINE, EMBASE, databases of ongoing trials, and conference proceedings of the American Society of Clinical Oncology and the American Society of Hematology (1980 to December 2015). We planned to include both full-text and abstract publications. Two review authors independently screened search results. SELECTION CRITERIA We included randomised controlled trials (RCTs) comparing prophylaxis with G(M)-CSF versus antibiotics for the prevention of infection in cancer patients of all ages receiving chemotherapy. All study arms had to receive identical chemotherapy regimes and other supportive care. We included full-text, abstracts, and unpublished data if sufficient information on study design, participant characteristics, interventions and outcomes was available. We excluded cross-over trials, quasi-randomised trials and post-hoc retrospective trials. DATA COLLECTION AND ANALYSIS Two review authors independently screened the results of the search strategies, extracted data, assessed risk of bias, and analysed data according to standard Cochrane methods. We did final interpretation together with an experienced clinician. MAIN RESULTS In this updated review, we included no new randomised controlled trials. We included two trials in the review, one with 40 breast cancer patients receiving high-dose chemotherapy and G-CSF compared to antibiotics, a second one evaluating 155 patients with small-cell lung cancer receiving GM-CSF or antibiotics.We judge the overall risk of bias as high in the G-CSF trial, as neither patients nor physicians were blinded and not all included patients were analysed as randomised (7 out of 40 patients). We considered the overall risk of bias in the GM-CSF to be moderate, because of the risk of performance bias (neither patients nor personnel were blinded), but low risk of selection and attrition bias.For the trial comparing G-CSF to antibiotics, all cause mortality was not reported. There was no evidence of a difference for infection-related mortality, with zero events in each arm. Microbiologically or clinically documented infections, severe infections, quality of life, and adverse events were not reported. There was no evidence of a difference in frequency of febrile neutropenia (risk ratio (RR) 1.22; 95% confidence interval (CI) 0.53 to 2.84). The quality of the evidence for the two reported outcomes, infection-related mortality and frequency of febrile neutropenia, was very low, due to the low number of patients evaluated (high imprecision) and the high risk of bias.There was no evidence of a difference in terms of median survival time in the trial comparing GM-CSF and antibiotics. Two-year survival times were 6% (0 to 12%) in both arms (high imprecision, low quality of evidence). There were four toxic deaths in the GM-CSF arm and three in the antibiotics arm (3.8%), without evidence of a difference (RR 1.32; 95% CI 0.30 to 5.69; P = 0.71; low quality of evidence). There were 28% grade III or IV infections in the GM-CSF arm and 18% in the antibiotics arm, without any evidence of a difference (RR 1.55; 95% CI 0.86 to 2.80; P = 0.15, low quality of evidence). There were 5 episodes out of 360 cycles of grade IV infections in the GM-CSF arm and 3 episodes out of 334 cycles in the cotrimoxazole arm (0.8%), with no evidence of a difference (RR 1.55; 95% CI 0.37 to 6.42; P = 0.55; low quality of evidence). There was no significant difference between the two arms for non-haematological toxicities like diarrhoea, stomatitis, infections, neurologic, respiratory, or cardiac adverse events. Grade III and IV thrombopenia occurred significantly more frequently in the GM-CSF arm (60.8%) compared to the antibiotics arm (28.9%); (RR 2.10; 95% CI 1.41 to 3.12; P = 0.0002; low quality of evidence). Neither infection-related mortality, incidence of febrile neutropenia, nor quality of life were reported in this trial. AUTHORS' CONCLUSIONS As we only found two small trials with 195 patients altogether, no conclusion for clinical practice is possible. More trials are necessary to assess the benefits and harms of G(M)-CSF compared to antibiotics for infection prevention in cancer patients receiving chemotherapy.

Abstract
OBJECTIVES We performed a meta-analysis to evaluate the impact of systemic antibiotic prophylaxis in hematopoietic stem cell transplantation (HSCT) recipients. METHODS We collected reports from PubMed, the Cochrane Library, EMBASE, CINAHL, and Web of Science, along with references cited therein. We included prospective, randomized studies on systemic antibiotic prophylaxis in HSCT recipients. RESULTS Seventeen trials with 1453 autologous and allogeneic HSCT recipients were included. Systemic antibiotic prophylaxis was compared with placebo or no prophylaxis in 10 trials and with non-absorbable antibiotics in two trials. Systemic antibiotics other than fluoroquinolones were evaluated in five of these 12 trials. Four trials evaluated the effect of the addition of antibiotics for gram-positive bacteria to fluoroquinolones. One trial compared two different systemic antibiotic regimens: fluoroquinolones versus trimethoprim-sulfamethoxazole. As a result, systemic antibiotic prophylaxis reduced the incidence of febrile episodes (OR 0.16; 95%CI 0.09-0.30), clinically or microbiologically documented infection (OR 0.38; 95%CI 0.22-0.63) and bacteremia (OR 0.31; 95%CI 0.16-0.59) without significantly affecting all-cause mortality or infection-related mortality. CONCLUSIONS Systemic antibiotic prophylaxis successfully reduced the incidence of infection. However, there was no significant impact on mortality. The clinical benefits of prophylaxis with fluoroquinolones were inconclusive because of the small number of clinical trials evaluated.

Abstract
Patients with cancer vary regarding the nature and level of immunocompromise. Both the underlying malignancy and therapy can influence risk of infectious complications. Therefore, decisions about antimicrobial prophylaxis must be guided by a number of factors: (1) the risk of infection; (2) the potential severity of infection and the likelihood of response to therapy; and (3) the safety and efficacy of antimicrobial prophylaxis. The potential for selection for antibiotic-resistant pathogens should also inform decisions about prophylaxis. When assessing clinical trial data on antimicrobial prophylaxis, two major criteria should be considered: the quality of studies supporting prophylaxis (randomized, blinded studies are optimal) and the expected benefit of prophylaxis, measured in terms of prevention of morbidity and potentially mortality. This chapter reviews the epidemiology and clinical trial data on prophylaxis against the major bacterial, viral, and fungal diseases in patients with cancer. Gaps in knowledge and alternative approaches, such as the use of newer diagnostics, are discussed.

Abstract
PURPOSE OF REVIEW To review the most recent data regarding the epidemiology, risks factors, and outcomes among hematopoietic stem cell transplant recipients with Clostridium difficile infection (CDI). RECENT FINDINGS With the emergence of an epidemic strain of C. difficile known as NAP1 in the early 2000s, rates of this infection have escalated globally. Hematopoietic stem cell transplant recipients appear to be one of the most vulnerable populations for the development of CDI. Traditional risk factors for CDI including antimicrobial exposure and older age are likely only a piece of the overall risk profile, with recent study results also emphasizing other factors such as transplant type, conditioning regimen, and graft-versus-host disease (GVHD). The relationship between CDI and subsequent development of GVHD, particularly of the gastrointestinal tract, is of specific interest. A bidirectional relationship of association has been highlighted in a number of recent studies and underscores the need for further prospective studies to address the potential indirect effects of alloreactivity induced by CDI. SUMMARY CDI has emerged as one of the most common infections in the early transplant period. Recent studies have begun to address the epidemiology of disease, risk factors for, and outcomes after infection in the stem cell transplant. However, more research is needed to unravel the observed relationship between CDI and GVHD.

Abstract
Bacterial infections are the most common cause for treatment-related mortality in patients with neutropenia after chemotherapy. Here, we discuss the use of antibacterial prophylaxis against bacteria and Pneumocystis pneumonia (PCP) in neutropenic cancer patients and offer guidance towards the choice of drug. A literature search was performed to screen all articles published between September 2000 and January 2012 on antibiotic prophylaxis in neutropenic cancer patients. The authors assembled original reports and meta-analysis from the literature and drew conclusions, which were discussed and approved in a consensus conference of the Infectious Disease Working Party of the German Society of Hematology and Oncology (AGIHO). Antibacterial prophylaxis has led to a reduction of febrile events and infections. A significant reduction of overall mortality could only be shown in a meta-analysis. Fluoroquinolones are preferred for antibacterial and trimethoprim–sulfamethoxazole for PCP prophylaxis. Due to serious concerns about an increase of resistant pathogens, only patients at high risk of severe infections should be considered for antibiotic prophylaxis. Risk factors of individual patients and local resistance patterns must be taken into account. Risk factors, choice of drug for antibacterial and PCP prophylaxis and concerns regarding the use of prophylactic antibiotics are discussed in the review.

Abstract
Immunocompromise is a commonly cited risk factor for Clostridium difficile infection (CDI). We reviewed the experimental and epidemiological literature on CDI in three immunocompromised groups, HIV-seropositive individuals, haematopoietic stem cell or bone marrow transplant recipients and solid organ transplant recipients. All three groups have varying degrees of impairment of humoral immunity, a major factor influencing the outcome of CDI. Soluble HIV proteins such as nef and immunosuppressive agents such as cyclosporin, azathioprine and mycophenalate mofetil modify signalling from the key cellular pathways triggered by C. difficile toxin A, although there is a paucity of data on how these factors may interact with pathways activated by toxin B. Despite this, there has been little direct investigation into the effect of immunosuppression on the pathogenesis of CDI. Epidemiological studies consistently show increased rates of CDI in these populations, which are higher in those with greater degrees of immunocompromise such as individuals with advanced AIDS not receiving combination antiretroviral therapy or allogeneic haematopoietic stem cell transplant recipients. Less consistently data suggests immunocompromise in each group also impacts rates of severe, recurrent or complicated CDI. However all these conditions are characterised by high levels of antibiotic use and prolonged hospital stay, both powerful drivers of CDI risk.

Abstract
BACKGROUND Bacterial infections are a major cause of morbidity and mortality in patients who are neutropenic following chemotherapy for malignancy. Trials have shown the efficacy of antibiotic prophylaxis in reducing the incidence of bacterial infections but not in reducing mortality rates. Our systematic review from 2006 also showed a reduction in mortality. OBJECTIVES This updated review aimed to evaluate whether there is still a benefit of reduction in mortality when compared to placebo or no intervention. SEARCH METHODS We searched the Cochrane Cancer Network Register of Trials (2011), Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library Issue 2, 2011), MEDLINE (1966 to March 2011), EMBASE (1980 to March 2011), abstracts of conference proceedings and the references of identified studies. SELECTION CRITERIA Randomised controlled trials (RCTs) or quasi-RCTs comparing different types of antibiotic prophylaxis with placebo or no intervention, or another antibiotic, to prevent bacterial infections in afebrile neutropenic patients. DATA COLLECTION AND ANALYSIS Two authors independently appraised the quality of each trial and extracted data from the included trials. Analyses were performed using RevMan 5.1 software. MAIN RESULTS One-hundred and nine trials (involving 13,579 patients) that were conducted between the years 1973 to 2010 met the inclusion criteria. When compared with placebo or no intervention, antibiotic prophylaxis significantly reduced the risk of death from all causes (46 trials, 5635 participants; risk ratio (RR) 0.66, 95% CI 0.55 to 0.79) and the risk of infection-related death (43 trials, 5777 participants; RR 0.61, 95% CI 0.48 to 0.77). The estimated number needed to treat (NNT) to prevent one death was 34 (all-cause mortality) and 48 (infection-related mortality).Prophylaxis also significantly reduced the occurrence of fever (54 trials, 6658 participants; RR 0.80, 95% CI 0.74 to 0.87), clinically documented infection (48 trials, 5758 participants; RR 0.65, 95% CI 0.56 to 0.76), microbiologically documented infection (53 trials, 6383 participants; RR 0.51, 95% CI 0.42 to 0.62) and other indicators of infection.There were no significant differences between quinolone prophylaxis and TMP-SMZ prophylaxis with regard to death from all causes or infection, however, quinolone prophylaxis was associated with fewer side effects leading to discontinuation (seven trials, 850 participants; RR 0.37, 95% CI 0.16 to 0.87) and less resistance to the drugs thereafter (six trials, 366 participants; RR 0.45, 95% CI 0.27 to 0.74). AUTHORS' CONCLUSIONS Antibiotic prophylaxis in afebrile neutropenic patients significantly reduced all-cause mortality. In our review, the most significant reduction in mortality was observed in trials assessing prophylaxis with quinolones. The benefits of antibiotic prophylaxis outweighed the harm such as adverse effects and the development of resistance since all-cause mortality was reduced. As most trials in our review were of patients with haematologic cancer, we strongly recommend antibiotic prophylaxis for these patients, preferably with a quinolone. Prophylaxis may also be considered for patients with solid tumours or lymphoma.

Abstract
AIMS Patients with haematologic malignancies have a reportedly high incidence of sulfamethoxazole (SMX) hypersensitivity. The objective of this study was to determine whether deficiencies in sulfonamide detoxification pathways, to include glutathione (GSH) and ascorbate (AA), and cytochrome b(5) (b5) and cytochrome b(5) reductase (b5R), were prevalent in these patients. A secondary pilot objective was to determine whether the incidence of drug hypersensitivity following intermittent trimethoprim-SMX (TMP-SMX) prophylaxis approached that reported for high dose daily regimens. METHODS Forty adult patients with haematologic malignancies (HM) and 35 healthy adults were studied; an additional 13 HM patients taking ascorbate supplements (HM-AA) were also evaluated. Twenty-two of 40 HM patients were prescribed and were compliant with TMP-SMX 960 mg three to four times weekly. RESULTS There were no significant differences between HM and healthy groups in plasma AA (median 37.2 µm vs. 33.9 µm) or red blood cell GSH (1.9 mmvs. 1.8 mm). However, plasma AA was correlated significantly with leucocyte b5/b5R reduction (r= 0.39, P= 0.002). Deficient b5/b5R activities were not found in HM patients. In fact, patients with chronic lymphocytic leukaemia or myeloma had significantly higher median activities (80.7 µmol mg(-1) min(-1)) than controls (18.9 µmol mg(-1) min(-1), P= 0.008). After 3-4 weeks of treatment, no patients developed SMX-specific T cells and only one patient developed rash. CONCLUSIONS Deficiencies of blood antioxidants and b5/b5R reduction were not found in this population with haematologic malignancies, and the development of skin rash and drug-specific T cells appeared to be uncommon with intermittent TMP-SMX prophylaxis.

Abstract
Critical illness is a dreaded complication in recipients of hematologic stem cell transplantation, with poor survival described in a number of early series. The perception of futility may impact the approach to therapy. Over the last 20 years, there have been significant advances in the application of intensive care, as well as changes in the management of patients before, during, and after transplantation. These advances and changes may have an impact on this traditionally poor survival. This article discusses the outcomes of critical illness in bone marrow and stem cell transplant recipients, and gives possible reasons for the apparent improvement in outcomes seen in more recent series.

However, both regimens have been shown to reduce the incidence of infections. Since no systematic review has compared the two regimens, a systematic review was undertaken. OBJECTIVES To compare the effectiveness of G-CSF or GM-CSF with antibiotics in cancer patients receiving myeloablative chemotherapy with respect to preventing fever, febrile neutropenia, infection, infection-related mortality, early mortality and improving quality of life. SEARCH STRATEGY We searched The Cochrane Library, MEDLINE, EMBASE, databases of ongoing trials, and conference proceedings of the American Society of Clinical Oncology and the American Society of Hematology (1980 to 2007). We planned to include both full-text and abstract publications. SELECTION CRITERIA Randomised controlled trials comparing prophylaxis with G-CSF or GM-CSF versus antibiotics in cancer patients of all ages receiving chemotherapy or bone marrow or stem cell transplantation were included for review. Both study arms had to receive identical chemotherapy regimes and other supportive care. DATA COLLECTION AND ANALYSIS Trial eligibility and quality assessment, data extraction and analysis were done in duplicate. Authors were contacted to obtain missing data. MAIN RESULTS We included two eligible randomised controlled trials with 195 patients. Due to differences in the outcomes reported, the trials could not be pooled for meta-analysis. Both trials showed non-significant results favouring antibiotics for the prevention of fever or hospitalisation for febrile neutropenia. AUTHORS' CONCLUSIONS There is no evidence for or against antibiotics compared to G(M)-CSFs for the prevention of infections in cancer patients.

Abstract
OBJECTIVE To use bone marrow transplantation (BMT) as a model for testing the association between hyperglycemia and infection. RESEARCH DESIGN AND METHODS This cohort study included 382 adults (6.5% with diabetes) who had no evidence of infection before neutropenia during BMT. Mean glucose was calculated from central laboratory and bedside measurements taken before neutropenia; the primary outcome was neutropenic infections. RESULTS Eighty-four patients (22%) developed at least one neutropenic infection, including 51 patients (13%) with bloodstream infections. In patients who did not receive glucocorticoids during neutropenia, each 10 mg/dl increase in mean preneutropenia glucose was associated with an odds ratio of 1.08 (95% CI 0.98-1.19) (P = 0.14) for any infection and 1.15 (1.03-1.28) (P = 0.01) for bloodstream infections, after adjusting for age, sex, race, year, cancer diagnosis, transplant type, and total glucocorticoid dose before neutropenia. In those who received glucocorticoids during neutropenia (n = 71), the adjusted odds ratio associated with a 10 mg/dl increase in mean glucose was 1.21 (1.09-1.34) (P < 0.0001) for any infection and 1.24 (1.11-1.38) (P < 0.0001) for bloodstream infections. There was no association between mean glycemia and long length of hospital stay, critical status designation, or mortality. CONCLUSIONS In a BMT population highly susceptible to infection, there was a continuous positive association between mean antecedent glycemia and later infection risk, particularly in patients who received glucocorticoids while neutropenic. Tight glycemic control during BMT and glucocorticoid treatment may reduce infections.

Abstract
We performed a retrospective study to examine the preventive effects of newquinolones for endogenous infection in patients receiving various allogeneic hematopoietic stem cell transplantation including bone marrow transplantation (BMT), peripheral blood stem cell transplantation (PBSCT), and cord blood transplantation (CBT). Forty-nine patients were enrolled. Ciprofloxacin or norfloxacin was orally administered for intestinal sterilization from day -14 until engraftment. As a result, the period from transplantation until engraftment was significantly longer in CBT group than in BMT group. The febrile index (the ratio of the febrile (> or =38.0 degrees C) period during neutropenia (< or =500 cells/mm(3)) and C-reactive protein (CRP)-positive index (the ratio of CRP-positive (> or =2.0 mg/dl) period during neutropenia) were comparable among the three groups. In addition, no gram-negative bacteria in stool was isolated in the three groups; that is, an endogenous infection of gram-negative bacteria, a potential pathogen, was well controlled by newquinolones. We should be careful when interpreting the results of this small study; however, newquinolones are clinically effective for endogenous infection of gram-negative bacteria in patients receiving not only BMT, but also PBSCT and CBT.

Abstract
Limited data exist regarding the incidence and factors associated with outcome of invasive Pseudomonal infections in hematopoietic cell transplant (HCT). A retrospective analysis of cases of invasive Pseudomonas aeruginosa infection and factors associated with outcome was performed. P. aeruginosa invasive infection occurred in 95 of 5772 patients (1.65%) a median of 63 days after HCT (range 5-1435). Only 28% of infections occurred during periods of neutropenia (absolute neutrophil count<500 cells/mm(3)). Infection-attributable mortality during the initial episode of infection was 35.8%. Factors associated with initial mortality included the presence of a copathogen and high-dose steroid use. Ten (16.4%) of those who survived the initial infection experienced a recurrence of P. aeruginosa infection at a median of 9 days (range 3-17) after stopping antibiotics and 60% of those died as a result of recurrent infection a median of 1 day (range 1-7) after onset of recurrence. Grade 3-4 graft-versus-host disease was associated with a higher risk of recurrent infection. The risk of recurrence was not influenced by the presence of copathogens. Thus, invasive P. aeruginosa infections are associated with high recurrence rates and mortality in this immunocompromised population. Aggressive attempts to reduce immunosuppression and to treat copathogens may help during the initial infection.

Abstract
Advances in the management of cancer, particularly the development of new chemotherapeutic agents, have greatly improved the survival and outcome of patients with hematologic malignancies and solid tumors; overall 5-year survival rates in cancer patients have improved from 39% in the 1960s to 60% in the 1990s.1 However, infection, caused by both the underlying malignancy and cancer chemotherapy, particularly myelosuppressive chemotherapy, remains a persistent challenge.

Abstract
Pneumocystis jiroveci pneumonia (PCP) has become a rare opportunistic infection due to the efficacy of prophylactic regimens. We conducted a 6-year retrospective study at our institution. A total of 13 cases of PCP were diagnosed among 519 patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT) (2.5%). In three patients, PCP occurred within the first 5 months following HSCT. These severely immunocompromised patients were receiving prophylaxis and had concomitant aspergillosis that caused rapid death in two of them. In 10 other patients, PCP occurred a median of 14.5 months after HSCT. In all these patients, PCP prophylaxis had been discontinued, mainly because of the suspected bone-marrow toxicity of the prophylactic regimen. Median CD4+ T cell count was 131/microl at diagnosis. Seven of these 10 patients were receiving immunosuppressive therapy for chronic graft versus host disease and three had a relapse of their hematological malignancy. One patient died from PCP despite high doses of cotrimoxazole. We conclude that PCP is still occurring after allogeneic HSCT, mainly as a late complication in patients in whom PCP prophylaxis had been prematurely discontinued. Long-term PCP prophylaxis should be maintained in patients receiving immunosuppressive drugs, and in those with low CD4+ T cell counts or a relapse of their hematological malignancy.

Abstract
BACKGROUND Bacterial infections are a major cause of morbidity and mortality in neutropenic patients following chemotherapy for malignancy. Trials have shown the efficacy of antibiotic prophylaxis in decreasing the incidence of bacterial infections, but not in reducing mortality rates. OBJECTIVES This review aimed to evaluate whether antibiotic prophylaxis in afebrile neutropenic patients reduced mortality when compared to placebo or no intervention. SEARCH STRATEGY Electronic searches on The Cochrane Cancer Network Register of Trials (2004), Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library Issue 4, 2004), MEDLINE (1966 to 2004) and EMBASE (1980 to 2004) and abstracts of conference proceedings; references of identified studies; the first author of each included trial was contacted. SELECTION CRITERIA RCTs or quasi-RCTs comparing different types of antibiotic prophylaxis with placebo or no intervention, or another antibiotic to prevent bacterial infections in afebrile neutropenic patients. DATA COLLECTION AND ANALYSIS Two authors independently appraised the quality of each trial and extracted data from the included trials. Relative risks (RR) or average differences, with their 95% confidence intervals (CI) were estimated. MAIN RESULTS One hundred trials (10,274 patients) performed between the years 1973 to 2004 met inclusion criteria. Antibiotic prophylaxis significantly decreased the risk for death when compared with placebo or no intervention (RR, 0.66 [95% CI 0.54 to 0.81]). The authors estimated the number needed to treat (NNT) in order to prevent 1 death from all causes as 60 (95% CI 34 to 268). Prophylaxis resulted in a significant decrease in the risk of infection-related death, RR 0.58 (95% CI 0.45 to 0.74) and in the occurrence of fever, RR 0.78 (95% CI 0.75 to 0.82). A reduction in mortality was also evident when the more recently conducted quinolone trials were analysed separately. Quinolone prophylaxis reduced the risk for all-cause mortality, RR 0.52 (95% CI, 0.37 to 0.84). AUTHORS' CONCLUSIONS Our review demonstrated that prophylaxis significantly reduced all-cause mortality. The most significant reduction in mortality was observed in trials assessing prophylaxis with quinolones. The benefit demonstrated in our review outweighs harm, such as adverse effects, and development of resistance, since all-cause mortality is reduced. Since most trials in our review were of patients with haematologic cancer, prophylaxis, preferably with a quinolone, should be considered for these patients.

Abstract
BACKGROUND Bacteremia occurs during hematopoietic stem cell transplant (HSCT) in 20%-25% of patients and the use of gut decontamination (GD) to decrease this risk is controversial. Our purpose was to determine the incidence of bacteremia and antimicrobial resistance post-HSCT in pediatric patients receiving GD, and to identify risk factors associated with infection. PROCEDURES This was a retrospective cohort study of 182 pediatric patients undergoing first HSCT for malignant disease at The Children's Hospital of Philadelphia from January, 1999 to December, 2002. We examined the impact of age, sex, race, diagnosis, disease status, conditioning regimen, recent bacteremia, stem cell source, donor, graft versus host disease prophylaxis agents, and mucositis severity using Cox proportional hazard models. GD consisted of amoxicillin (azithromycin, if penicillin allergic) and oral gentamicin. Outcome was first episode of bacteremia prior to absolute neutrophil count (ANC) 500/mm(3). Antibiotic susceptibilities were performed on all isolates. RESULTS Seventy-four patients (41%) developed bacteremia. The majority were Gram-positive cocci, with Staphylococcal (50%) and Streptococcal species (28%) the most common. Gram-negative organisms were identified in 22% with Pseudomonas (5.7%) and Klebsiella species (3.4%) the most common. Of the Streptococcal infections, 72% were resistant to ampicillin; only 25% of the Gram-negative bacteria were resistant to gentamicin. Race was the only factor associated with early bacteremia (hazard ratio 2.3 for non-Caucasian, non-African-American patients, CI 1.3-4.3, P = 0.007). CONCLUSIONS Early bacteremia is common after HSCT, despite the use of GD. Resistant Gram-positive organisms predominate, consistent with recent trends in immunocompromised patients. Although used in practice, there is no clear evidence for the efficacy of GD and this study provides the basis upon which to develop a randomized clinical trial evaluating the current GD regimen with placebo.

Abstract
Patients undergoing allogeneic stem cell transplantation are at high risk for infection with a variety of pathogens during different phases of the procedure. Bacteria and fungi predominate the first phase until engraftment. During the second phase, from engraftment to about day 100, major infectious problems are caused by fungi and cytomegalovirus. Both pathogens remain important under continued immunosuppression, however, in the late post-transplantation period infections with encapsulated bacteria may become a problem. In this review the Infectious Diseases Working Party of the DGHO gives recommendations for prophylaxis of infections under allogeneic stem cell transplantation with drugs and other measures. The aim of the group was to do this on an evidence-based-medicine rating, if possible.

Abstract
The use of oral prophylactic antibiotics in oncology patients is still a matter of debate. A systematic review was performed to assess the evidence for the effectiveness of oral prophylactic antibiotics to decrease bacteraemia and infection-related mortality in oncology patients during neutropenic episodes. Medline, Embase and the Cochrane register of controlled trials were searched from 1966 until 2002. The main outcome was the number of patients with documented bacteraemia (Gram-negative or Gram-positive bacteraemia) and infection related mortality. Data-extraction and quality assessment were performed independently by two reviewers. A total of 22 trials met the inclusion criteria. Seventeen trials compared prophylaxis (quinolones or Trimethoprim/sulfamethoxazole (TMP/SMZ)) to no prophylaxis. The incidence of Gram-negative bacteraemia decreased significantly (pooled OR 0.39, 95% CI 0.24-0.62) without an increase in Gram-positive bacteraemia. Quinolone-based regimens showed a stronger reduction in Gram-negative bacteraemia while TMP/SMZ based regimens were more effective in Gram-positive bacteraemia. Infection related mortality due to bacterial causes decreased with the use of prophylactic antibiotics (pooled OR 0.49, 95% CI 0.27-0.88). No increase in fungaemia or fungal related mortality was seen with the use of oral prophylaxis. In conclusion, this study has shown that oral prophylactic antibiotics decreased Gram-negative bacteraemia and infection related mortality due to bacterial causes during neutropenic episodes in oncology patients.

Abstract
Pneumocystis infection in humans was originally described in 1942. The organism was initially thought to be a protozoan, but more recent data suggest that it is more closely related to the fungi. Patients with cellular immune deficiencies are at risk for the development of symptomatic Pneumocystis infection. Populations at risk also include patients with hematologic and nonhematologic malignancies, hematopoietic stem cell transplant recipients, solid-organ recipients, and patients receiving immunosuppressive therapies for connective tissue disorders and vasculitides. Trimethoprim-sulfamethoxazole is the agent of choice for prophylaxis against Pneumocystis unless a clear contraindication is identified. Other options include pentamidine, dapsone, dapsone-pyrimethamine, and atovaquone. The risk for PCP varies based on individual immune defects, regional differences, and immunosuppressive regimens. Prophylactic strategies must be linked to an ongoing assessment of the patient's risk for disease.

Abstract
In the present study, we analyze the efficacy of prophylaxis with meropenem in patients receiving a matched related donor allogeneic transplant. In total, 38 patients were sequentially treated with meropenem starting on the day of the first febrile episode (n=17, group A) vs prophylactic meropenem starting on the first day with <500/mm(3) granulocytes (n=21, group B), and maintained until resolution of fever or after granulocyte count >500/mm(3). Of these, 16 (94%) patients in group A developed fever as compared to 16 (76%) in group B (P=0.02). While only one patient in group A did not require first-line antibiotherapy, there were seven (33%) in group B who did not require it (P=0.01) since fever lasted less than 72 h. In addition, 52% patients in group B did not require second-line antibiotics as compared to 11% among patients in group A (P=0.04). In multivariate analysis prophylaxis with meropenem (HR=2.83, 95% CI (1-8.02); P=0.04) and disease status at transplant (HR for early stage=0.15, 95% CI (0.04-0.62); P=0.04) significantly influenced the development of fever. In conclusion, the current pilot study suggests that the use of prophylaxis with meropenem during the period of neutropenia in patients undergoing allogeneic transplantation favorably affects the morbidity of the procedure by reducing febrile episodes.

Abstract
This article reviews clinical trials of outpatient management of fever and neutropenia in pediatric cancer patients. The syndrome of fever and neutropenia is discussed, and strategies of identifying patients at low risk for complex or fatal infections are described. A number of clinical trials in a wide range of clinical settings and countries have demonstrated that low risk pediatric cancer patients with fever and neutropenia can be prospectively identified and safely treated as outpatients. In addition outpatient management has been shown to be less costly than conventional intravenous therapy in hospitalized patients. Oral fluoroquinolones, including ciprofloxacin, have been used as a component of therapy in several trials because of their ease of administration and their activity against the majority of pathogenic bacteria causing illness in this group. The article also discusses the role of antibiotic prophylaxis of fever and neutropenia in certain high risk settings, such as hematopoietic stem cell transplantation. In selected high risk patients, prophylactic use of limited spectrum fluoroquinolones such as ciprofloxacin may reduce the incidence of Gram-negative bacteremias. Use of fluoroquinolone therapy as prophylaxis, however, is controversial because of concerns about an emergence of resistant organisms. Prudent use of fluoroquinolones as therapy and prophylaxis is essential to prolonging the benefits of this class of compounds.

Abstract
Gram-negative infection is an important cause of morbidity and mortality after unrelated donor-bone marrow transplantation (UD-BMT). We performed a retrospective case-control study to examine the risk factors, prophylaxis, therapy and outcome of Gram-negative bacteraemia (GNB) in 428 patients undergoing UD-BMT. The incidence of GNB was 3.6% in children and 19% in adults. Of the adults, 11% developed GNB >60 days post UD-BMT. Predisposing risk factors for GNB included 'high-risk' disease status, chronic graft-versus-host disease and use of systemic steroids. Fever, a raised C-reactive protein (CRP) and hypotension were common findings at presentation. Patients were routinely given prophylactic ciprofloxacin: resistance to this antibiotic was seen in 33% of isolates. We identified an age-matched control group undergoing UD-BMT over the same time period as the study group. Gram-positive bacteraemia was significantly more common in cases than controls. Mortality from GNB was 17% in children and 24% in adults. We conclude that GNB is a common complication of UD-BMT with a high associated mortality. Patients should be educated further to present rapidly with symptoms suggestive of infection.

Abstract
We review data on the in-vitro, ex-vivo, in-vivo, and clinical effects of fluoroquinolones on the synthesis of cytokines and their mechanisms of immunomodulation. In general, most fluoroquinolone derivatives superinduce in-vitro interleukin 2 synthesis but inhibit synthesis of interleukin 1 and tumour necrosis factor (TNF)alpha; furthermore, they enhance significantly the synthesis of colony-stimulating factors (CSF). Fluoroquinolones affect in-vivo cellular and humoral immunity by attenuating cytokine responses. Interleukins 10 and 12 have an important role in the functional differentiation of immunocompetent cells and trigger the initiation of the acquired immune response. In addition, certain fluoroquinolones were seen to enhance haematopoiesis by increasing the concentrations of CSF in the lung as well as in the bone marrow and shaft. Those fluoroquinolones exerting significant effects on haematopoiesis were those with a cyclopropyl moiety at position N1 of their quinolone core structure. Mechanisms that could explain the various immunomodulatory effects of fluoroquinolones include: (1) an effect on intracellular cyclic adenosine-3',5'-monophosphate and phosphodiesterases; (2) an effect on transcription factors such as nuclear factor (NF)kappaB, activator protein 1, NF-interleukin-6 and nuclear factor of activated T cells; and (3) a triggering effect on the eukaryotic equivalent of bacterial SOS response with its ensuing intracellular events. Further studies are required, especially in the clinical setting to exploit fully the potential of the immunomodulatory effect of fluoroquinolones during, for example, immunosuppression, chronic airway inflammatory diseases, and sinusitis.

Abstract
BACKGROUND Infections remain a major cause of morbidity and mortality in patients undergoing autologous or allogeneic hematopoietic stem cell transplantation (HSCT). About 80% of patients experience fever during aplasia and early engraftment despite oral antibacterial chemoprophylaxis. METHODS In a pilot study, 50 patients undergoing autologous or allogeneic HSCT received a prophylactic antibacterial treatment with intravenous piperacillin/tazobactam beginning on day of stem cell or bone marrow transfusion. They were analyzed retrospectively for frequencies of fever of unknown origin (FUO), documented infection, bacteremia and death because of infection. Furthermore, data from microbiological monitoring and tolerability were evaluated. RESULTS Among 28 autologous transplanted patients, 10 (36%) developed fever more than 38.5 degrees C; 9/10 FUO, 1/28 pulmonary infiltrates. Eighteen patients (64%) remained without any symptom of infection. In the allogeneic group (n = 22), there were eight patients (36%) with FUO, and five patients (23%) with documented infections (pneumonia 2, enteritis 1, pyelonephritis 1, Escherichia coli bacteremia 1). In nine patients (41%), escalation of antimicrobial treatment was not necessary. The majority of detected microbes in cultures of throat and nose secretions, blood, urine and stool were gram-positive bacteria (77.8%), among them Staphylococcus epidermidis (23.5%), streptococci (group A, B, C; 21.0%) and enterococci (10.6%). Incidence of gram-negative bacteria and fungi was similar with 11.8% and 10.4%, respectively. The most frequent gram-negative strains were Escherichia coli (6.5%) and Pseudomonas aeruginosa (1.7%). There was no severe toxicity or hypersensitivity. CONCLUSION Compared to oral decontamination and chemoprophylaxis, an intravenous prophylactic regimen as described above could be an effective and well-tolerated approach in prevention of bacterial infections and related complications, with a higher acceptance in recipients of bone marrow or stems cell grafts. Further evaluation in comparison with fluoroquinolone prophylaxis regarding efficacy, development of resistances as well as cost-benefit analyses is warranted.

Abstract
BACKGROUND Infection is still a frequent cause of morbidity and mortality in acute myelogenous leukemia (AML) patients receiving chemotherapy. Recently the main cause of infection has changed from gram-negative to gram-positive bacteria and the resistance to antibiotics has increased. This study aimed to access the effectiveness of antimicrobial prophylaxis (AP) with orally absorbable antibiotics. METHODS Ninety-five AML patients receiving chemotherapy at Catholic Hemopoietic Stem Cell Transplantation Center from March 1999 to July 1999 were randomly divided into the AP group (250 mg ciprofloxacin twice a day, 150 mg roxithromycin twice a day, 50 mg fluconazole once a day) and the control group for a prospective analysis. RESULTS The incidence of fever was 82.6% in the AP group and 91.6% in the control group (p = 0.15). Though classification and sites of infections showed no difference between the two groups, the catheter associated infection occurred more frequently in the AP group in significance. The time interval between initiation of chemotherapy and onset of fever, white blood cell (WBC) count at the onset of fever, duration of leukopenia (WBC < 1,000/mm3), duration of systemic antibiotic therapy, mortality due to infection and hospitalization period from the data starting chemotherapy showed no differences between the two groups. Infections due to gram negative bacteria decreased to 33.3% in the AP group (vs. 92% in the control group), but infections due to gram positive bacteria increased to 66.7% (vs. 8% in the control group). Gram negative bacteria showed 100% resistance to ciprofloxacin in the AP group and gram-positive bacteria showed 90-100% resistance to erythromycin, regardless of the presence of AP. CONCLUSION The AP could not reduce the occurrence of infection or infection associated death in AML patients receiving chemotherapy. On considering increased gram-positive infection and resistance to fluoroquinolone and macrolide, routine prescription of AP should be reconsidered. Further studies that assess the effectiveness of AP in other malignancies, aplastic anemia and bone marrow transplantation are required.

Abstract
Autologous peripheral blood stem cells (PBSC), for transplantation following high-dose chemotherapy, are collected using regimens containing cytokines with or without chemotherapy. The added period of neutropenia prior to stem cell transplantation (SCT) in patients receiving chemotherapy mobilization may increase the risk of infections following transplantation. We studied the incidence of culture-positive infections in 107 consecutive patients who were divided into three groups, according to whether they experienced extended neutropenia during chemotherapy for stem cell mobilization as well as post autotransplant. All the patients received antibiotic prophylaxis and hematopoietic growth factors during neutropenia. The total duration of pre-transplant neutropenia differed among the three mobilization schemes (growth factors alone; one cycle; or two cycles of chemotherapy plus growth factor for mobilization) at 0, 6 and 18 days, respectively (median). However the post-autograft time to myeloid engraftment was similar at 10 days (median). The incidence of culture-proven infections in all three groups was similar. Using fluconazole for yeast prophylaxis, 40% patients developed gastrointestinal colonization with yeast, and the majority of speciated isolates were Candida glabrata. Bacteremia developed in 22% and 9% of patients with S. epidermidis and Gram-negative organisms, respectively, while 11% developed C. difficile-associated diarrhea. In conclusion, treatment using none, one or two cycles of mobilizing chemotherapy pre-transplant does not influence the overall incidence of infections among autologous SCT recipients. However, although post-transplant neutropenia is brief, infections remain a significant cause of morbidity.

Abstract
Following a 2-year study, the combination of oral ciprofloxacin and colistin has been used continuously for 10 years without the emergence of resistance. During a 2-year period (1987-1989), we compared ciprofloxacin + colistin (CIP + COL) with neomycin + colistin (NEO + COL) in a randomized trial--combinations chosen because of the potential for prophylaxis of Gram-negative infection by ciprofloxacin, with colistin given to reduce the risk of emergence of resistance. Sixty-four patients with similar demographics in each arm were evaluable for efficacy analysis. Patients on CIP + COL had a significantly lower proportion of neutropenic days with fever (P < 0.001) and neutropenic days on intravenous antibiotics (P < 0.001) than patients on NEO + COL. A total of 54 (15 bacteriologically documented) pyrexial episodes occurred in patients on CIP + COL and 77 (41 bacteriologically documented) in patients on NEO + COL. Only two Gram-negative bacterial infections occurred in the CIP + COL arm compared with 16 in the NEO + COL arm. No Staphylococcus aureus infections occurred in the CIP + COL group compared with 10 in the other patients. Two CIP-resistant Gram-negative bacilli were isolated from patients on CIP + COL compared with 13 NEO-resistant Gram-negative bacilli from patients on NEO + COL. Following a subsequent decade of unchanged use of this prophylactic strategy in neutropenic patients, a 2-year follow-up study between 1 January 1998 and 31 December 1999 showed 66 significant infections during 700 [corrected] neutropenic episodes. Thirty-five of the 111 (31%) isolates were ciprofloxacin-resistant, involving 5% of the neutropenic episodes [corrected].

Abstract
BACKGROUND CDE (cyclophosphamide, doxorubicin, etoposide) is one of the standard chemotherapy regimens in the treatment of small-cell lung cancer (SCLC), with myelosuppression as dose-limiting toxicity. In this trial the impact of prophylactic antibiotics on incidence of febrile leucopenia (FL) during chemotherapy for SCLC was evaluated. PATIENTS AND METHODS Patients with chemo-naïve SCLC were randomized to standard-dose CDE (C 1,000 mg/m2 day 1, D 45 mg/m2 day 1, E 100 mg/m2 days 1-3. i.v., q 3 weeks, x5) or to intensified CDE chemotherapy (125% dose, q 2 weeks, x4, with filgrastim 5 microg/kg/day days 4-13) to assess the impact on survival (n = 240 patients). Patients were also randomized to prophylactic antibiotics (ciprofloxacin 750 mg plus roxithromycin 150 mg, bid. days 4-13) or to placebo in a 2 x 2 factorial design (first 163 patients). This manuscript focuses on the antibiotics question. RESULTS The incidence of FL during the first cycle was 25% of patients in the placebo and 11% in the antibiotics arm (P = 0.010; 1-sided), with an overall incidence through all cycles of 43% vs. 24% respectively (P = 0.007; 1-sided). There were less Gram-positive (12 vs. 4), Gram-negative (20 vs. 5) and clinically documented (38 vs. 15) infections in the antibiotics arm. The use of therapeutic antibiotics was reduced (P = 0.013; 1-sided), with less hospitalizations due to FL (31 vs. 17 patients, P = 0.013: 1-sided). However, the overall number of days of hospitalization was not reduced (P = 0.05; 1-sided). The number of infectious deaths was nil in the antibiotics vs. five (6%) in the placebo arm (P = 0.022; 2-sided). CONCLUSIONS Prophylactic ciprofloxacin plus roxithromycin during CDE chemotherapy reduced the incidence of FL, the number of infections, the use of therapeutic antibiotics and hospitalizations due to FL by approximately 50%, with reduced number of infectious deaths. For patients with similar risk for FL, the prophylactic use of antibiotics should be considered.

Abstract
Numerous advances have been made in the management of infection in HSCT recipients. With increasing knowledge the authors are able to prevent several serious infections from occurring, and reduce the severity of infections once they occur. Despite these advances, several previously unrecognized pathogens have emerged and pose risks to this population. Ongoing surveillance and reporting of atypical infections are warranted. Transplant and infectious disease clinicians alike must be vigilant to the shifts in infectious syndromes as a consequence of various prophylaxis and preemptive strategies, and be ready to modify empiric strategies to meet the changing microbiologic milieu. As we increase our understanding of the HSCT process, and use the immune system rather than relying on high-dose chemotherapy, the authors are likely to reduce toxicities and improve patient outcomes.

Abstract
We analyzed the effect of the two quinolones moxifloxacin and ciprofloxacin on the repopulation of hematopoietic organs and on the production of cytokines by various organs of cyclophosphamide (CP)-induced leukopenic mice. The effect was compared to that of G-CSF. Cyclophosphamide injection induced a severe leukopenia, with nadir at day 4 post-injection. All the quinolone and G-CSF-treated animals showed WBC>500/microL at the nadir, compared to 50% of saline-treated mice. Cyclophosphamide induced a marked decrease in the number of myeloid progenitors (CFU-C) in bone marrow (BM) and spleen. Quinolone or G-CSF treatment resulted in a 1.4-4.3-fold increase in CFU-C numbers in the BM; no enhancement was observed in the spleen. Treatment with CP resulted in enhanced colony-stimulating activity (CSA) in bone shaft and spleen and decreased activity in bladder and lung. Treatment of CP-injected mice with quinolones significantly enhanced CSA in the bone shaft, spleen, lung and bladder on different days. In normal mice the highest levels of GM-CSF and IL-6 were observed in lung-conditioned medium (compared to bone shaft, spleen and bladder). Injection of CP resulted in a 22.5- and 93-fold decrease in GM-CSF and IL-6 levels, respectively, in lung-conditioned medium, while treatment with quinolones resulted in 2-4-fold increase in GM-CSF with no effect on IL-6 production. G-CSF treatment had no enhancing effect on GM-CSF nor on IL-6 production. We conclude that moxifloxacin and ciprofloxacin administered to CP-injected mice revert some of the immune suppressive effects of cyclophosphamide.

Abstract
Few studies have examined the specific incidence of infections after autologous bone marrow transplantation (BMT) or peripheral stem cell transplantation (PSCT) for treatment of breast cancer. We reviewed the medical records of 127 consecutive patients who underwent autologous BMT or PSCT for breast cancer at the University of Pennsylvania Medical Center from 1 May 1991 through 31 March 1995 and through 1 year of follow-up. The mean duration of neutropenia after transplantation was 10 days. Initial infections included catheter-site cellulitis (in 20 patients [16%]), bacteremia (17 [13%]), Clostridium difficile colitis (13 [10%]), and urinary tract infection (in 10 [8%]); there was only 1 documented invasive fungal infection (1% of patients). The mortality from infection was 2%. Infections during the 1 year follow-up included upper respiratory infections (11 patients [10%]) and dermatomal zoster (9 [8%]); neither was significantly associated with death. This group of patients who underwent BMT or PSCT for breast cancer had a low rate of infectious morbidity and mortality. Viral and fungal infections were rare despite inconsistent prophylaxis.

Abstract
Infection remains an important cause of morbidity and mortality after bone marrow or stem cell transplantation. To evaluate the role of obtaining blood cultures for intermittent or persistent fever in neutropenic patients on antibiotic therapy, we performed a retrospective chart review of 196 consecutive patients admitted to the Bone Marrow Transplant Unit at the University of North Carolina Hospitals from 1995 to 1998. From the cohort of 196 patients, 154 patients developed neutropenic fever. The initial blood culture was positive in 16 of 145 patients during the first fever episode giving a prevalence of 11%. From the total of 109 patients that had blood cultures drawn after day 1 of fever, five patients had blood cultures positive for a pathogen, a prevalence of 4.6%. In only one patient, did blood cultures drawn after day 1 identify an organism not present on day 1 (prevalence 0.9%). After reviewing the results in the first 105 patients, we changed our timing of collection of blood cultures. Forty-nine patients were treated in this manner and we found that the mean number of blood cultures decreased from 9.2 to 4.7 per patient without a change in the frequency of infectious complications or length of hospitalization.

Abstract
PURPOSE To determine whether the addition of rifampin to a quinolone-based antibacterial prophylactic regimen in patients undergoing high-dose chemotherapy (HDC) with peripheral-blood stem-cell transplantation (PBSCT) decreases the incidence of neutropenia and fever, Gram-positive bacteremia, and infection-related morbidity. PATIENTS AND METHODS Patients with solid tumors undergoing HDC with PBSCT were randomized to receive prophylactic antibiotics with either ciprofloxacin 500 mg orally every 8 hours or the same ciprofloxacin regimen with rifampin 300 mg orally every 12 hours. Prophylaxis was started 48 hours before stem-cell reinfusion. Patients were monitored to document the occurrence of neutropenia and fever, incidence and cause of bacterial infection, time to onset and duration of fever, requirement for intravenous antimicrobials, and length of hospital admission. RESULTS Sixty-five patients were randomized to receive ciprofloxacin and 65 to receive ciprofloxacin plus rifampin, and from these groups, 62 and 61 were assessable, respectively. The proportion of patients who developed neutropenia and fever was 87% in the group treated with ciprofloxacin and 78% in the group treated with ciprofloxacin and rifampin (P =.25). Although there was a trend toward a reduction in the overall incidence of bacteremia (12 v 4 patients), and Gram-positive bacteremia (8 v 2 patients) with the addition of rifampin, none of these comparisons was statistically significant (P =.05 and P =.09, respectively). CONCLUSION The results of this study, which demonstrate that rifampin does not improve ciprofloxacin antibacterial prophylaxis in cancer patients undergoing HDC with PBSCT support but that it does increase the occurrence of undesirable side effects, do not support the routine use of rifampin in this setting.
