Intensive Care Med 2022; 48:311-321. [PMID: 35106617 PMCID: PMC8866359 DOI: 10.1007/s00134-021-06609-6] [Citation(s) in RCA: 90] [Impact Index Per Article: 45.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2021] [Accepted: 12/21/2021] [Indexed: 12/11/2022]
Abstract
PURPOSE Insufficient antimicrobial exposure is associated with worse outcomes in sepsis. We evaluated whether therapeutic drug monitoring (TDM)-guided antibiotic therapy improves outcomes. METHODS Randomized, multicenter, controlled trial from January 2017 to December 2019. Adult patients (n = 254) with sepsis or septic shock were randomly assigned 1:1 to receive continuous infusion of piperacillin/tazobactam with dosing guided by daily TDM of piperacillin or continuous infusion with a fixed dose (13.5 g/24 h if eGFR ≥ 20 mL/min). Target plasma concentration was four times the minimal inhibitory concentration (range ± 20%) of the underlying pathogen, respectively, of Pseudomonas aeruginosa in empiric situation. Primary outcome was the mean of daily total Sequential Organ Failure Assessment (SOFA) score up to day 10. RESULTS Among 249 evaluable patients (66.3 ± 13.7 years; female, 30.9%), there was no significant difference in mean SOFA score between patients with TDM (7.9 points; 95% CI 7.1-8.7) and without TDM (8.2 points; 95% CI 7.5-9.0) (p = 0.39). Patients with TDM-guided therapy showed a lower 28-day mortality (21.6% vs. 25.8%, RR 0.8, 95% CI 0.5-1.3, p = 0.44) and a higher rate of clinical (OR 1.9; 95% CI 0.5-6.2, p = 0.30) and microbiological cure (OR 2.4; 95% CI 0.7-7.4, p = 0.12), but these differences did not reach statistical significance. Attainment of target concentration was more common in patients with TDM (37.3% vs. 14.6%, OR 4.5, CI 95%, 2.9-6.9, p < 0.001). CONCLUSION TDM-guided therapy showed no beneficial effect in patients with sepsis and continuous infusion of piperacillin/tazobactam with regard to the mean SOFA score. Larger studies with strategies to ensure optimization of antimicrobial exposure are needed to definitively answer the question.

Abstract
Hintergrund Sepsis ist weltweit jährlich für geschätzt 11 Mio. Todesfälle verantwortlich. Die Epidemiologie sepsisassoziierter Todesfälle ist in Deutschland unzureichend verstanden, da Sepsis bisher nicht über die deutsche unikausale Todesursachenstatistik erfasst werden kann. Ziel der Arbeit Epidemiologie und Charakteristika sepsisassoziierter Krankenhaustodesfälle sollen analysiert sowie regionale Unterschiede beschrieben werden. Material und Methoden Retrospektive Beobachtungsstudie basierend auf der deutschlandweiten fallpauschalenbezogenen Krankenhausstatistik (DRG-Statistik) 2016. Sepsisassoziierte Krankenhaustodesfälle wurden über explizite und implizite Sepsis-ICD-10-GM(Internationale statistische Klassifikation der Krankheiten und verwandter Gesundheitsprobleme, 10. Revision, German Modification)-Codierungen identifiziert. Verstorbene wurden anhand der klinischen Merkmale und ihres Wohnortes entsprechend Amtlichem Gemeindeschlüssel (AGS-5-Steller) charakterisiert. Basierend auf der Bevölkerungsstatistik wurde der Anteil an den Gesamttodesfällen ermittelt. Ergebnisse 2016 gab es in Deutschland 58.689 mit explizit codierter Sepsis assoziierte Krankenhaustodesfälle (14,1 % aller Krankenhaustodesfälle). Die Mortalität betrug 73/100.000 Einwohner und variierte 1,8-fach zwischen den Bundesländern und 7,9-fach zwischen den Kreisen. 6,4 % der deutschlandweiten Todesfälle waren sepsisassoziierte Krankenhaustodesfälle. Dieser Anteil war am höchsten in der Altersgruppe der 40- bis 64-Jährigen (9,6 %) und höher bei Männern als bei Frauen (7,7 % vs. 5,2 %). Im Vergleich dazu betrug der Anteil von implizit codierten sepsisassoziierten Krankenhaustodesfällen 47,2 % an allen Krankenhaustodesfällen und 21,6 % an allen Todesfällen. Diskussion Auch wenn die direkte Todesursache nicht sicher ableitbar ist, lässt sich aus dem hohen Anteil sepsisassoziierter Todesfälle an den Krankenhaustodesfällen der Bedarf weiterer Forschung und epidemiologischer Surveillance ableiten, zum Beispiel in Kohortenstudien oder auf Basis von multikausalen Todesursachenstatistiken. Zusatzmaterial online Zusätzliche Informationen sind in der Online-Version dieses Artikels (10.1007/s00103-021-03427-5) enthalten.

Abstract
Urosepsis is a very serious condition with a high mortality rate. The immune response is in the center of pathophysiology. The therapeutic management of these patients includes surgical treatment of the source of infection, antibiotic therapy and life support. The management of this pathology is multidisciplinary and requires good collaboration between the urology, intensive care, imaging and laboratory medicine departments. An imbalance of pro and anti-inflammatory cytokines produced during sepsis plays an important role in pathogenesis. The study of cytokines in sepsis has important implications for understanding pathophysiology and for development of other therapeutic solutions. If not treated adequately, urosepsis may lead to serious septic complications and organ sequelae, even to a lethal outcome.

Abstract
BACKGROUND Early detection of acute kidney injury (AKI) is crucial in the management of multiple-organ dysfunction syndrome in severely injured patients. Standard laboratory parameters usually increase with temporal delay. Therefore, we evaluated neutrophil gelatinase-associated lipocalin (NGAL) as an early marker for acute kidney injury. PATIENTS AND METHODS We retrospectively evaluated patients admitted to a level 1 trauma center. We collected clinicodemographic data and measured kidney-related factors and plasma cytokines. RESULTS A total of 39 patients were included. Patients with AKI had significantly higher levels not only of serum creatinine and urea, but also of NGAL (all p<0.001) than patients without AKI. The optimal NGAL cut-off value was determined to be 177 ng/ml, showing significant correlation with imminent or manifest AKI (p<0.001). Other independent markers correlated with AKI included pre-existing chronic kidney disease, use of catecholamines, and severe injury (p<0.001). CONCLUSION The serum level of NGAL is feasible early predictor of AKI.

Abstract
Urosepsis after upper urinary tract endoscopic lithotripsy (UUTEL) may cause uroseptic shock with high mortality, which can be prevented if early diagnosis and timely intervention are implemented with help of a diagnostic protein panel. The plasma of five rabbits of uroseptic shock and five controls was subjected to exploratory proteomics to search biomarker candidates from proteomic profiles related to uroseptic shock. Then, plasma from 21 nonsepsis and 20 urosepsis patients according to European diagnostic criteria of sepsis was enrolled in the validation study via targeted proteomics. Changes in a massive number of plasma proteins, mainly enriched in immune regulation, coagulation, structural repair, and transport activity, were observed in the rabbit model of septic shock. Fifteen proteins were identified as differential expression proteins between sepsis and nonsepsis patients. A diagnostic model composed of three proteins lipopolysaccharide-binding protein (LBP), clusterin (CLU), and vascular cell adhesion protein 1 (VCAM1) was developed for the early detection (2 hours postoperatively) of urosepsis after UUTEL, with a high area under the receiver operating characteristic (ROC) curve of 0.921. In conclusion, changes in the proteomic profile may reflect the underlying biological mechanisms during the development of urosepsis and produce diagnostic biomarkers for the early detection of urosepsis after UUTEL.

Abstract
BACKGROUND/AIM Multiple organ dysfunction syndrome (MODS) is the leading cause of late posttraumatic mortality. This study analyzed the prognostic values of osteoprotegerin (OPG) and neutrophil gelatinase-associated lipocalin (NGAL/lipocalin 2) compared to interleukin-6 (IL-6) in multiply injured patients. PATIENTS AND METHODS A retrospective observational cohort study on multiply injured patients with an injury severity score (ISS) of ≥16 was performed. OPG, NGAL and IL-6 blood concentrations were measured. Statistical analysis comprised receiver-operating-characteristic (ROC) analysis with the corresponding area under the curve (AUC). RESULTS Thirty-nine patients with a mean ISS of 34±11 were included. Fourteen patients (36%) developed MODS and 8 patients (21%) died. Plasma levels of NGAL, OPG, and IL-6 were significantly elevated in the MODS+ group. Each biomarker positively correlated with MODS score and diagnosis of MODS. CONCLUSION NGAL and OPG might be indicative of MODS and could have the potential to be biomarkers in the early detection of patients at risk of posttraumatic MODS.

Abstract
Introduction This project addresses the important problem of sepsis sequelae resulting in frequent hospital readmissions and higher mortality rate in the post-discharge period. However, neither specific diagnostic methods nor standards for rehabilitation of sepsis patients have been introduced yet. The aim of this study is to evaluate the effectiveness of two different multiparameter-monitored rehabilitation treatments in order to improve the health status and quality of life of sepsis survivors. Methods Decades of failed randomized controlled trials involving sepsis patients strongly suggest the need for a paradigm change. Therefore, we designed a prospective, interventional, controlled, pragmatic, patient-centred trial based on the principles of personalized medicine. Sixty post-sepsis patients after hospital discharge will be individually assigned to a control group (without intervention) and two groups with 3-month diagnostically monitored rehabilitation programs based either on the recumbent cycloergometer training or on the experimental hyperbaric oxygen therapy. In all of the patients a wide range of physiological (spirometry, ECG/cycloergometer exercise test), haematological (microscopy) and biochemical (blood tests) parameters will be assessed at hospital discharge and during subsequent 3 months in order to monitor changes of their physical capacity, immunity and degree of post-sepsis organ damage/recovery. For quality of life monitoring a novel tool—“Life After Sepsis Survey”—will be applied. Planned Outcomes A set of composite quantitative indices resulting from laboratory measurement data combined with the quality of life questionnaire data will constitute the primary outcomes whereas mortality rate and hospital readmission number will be counted as the secondary outcomes. Conclusions Critical analysis of past trials prompted us to implement multiple improvements in tools and procedures. The results of this trial will contribute to the development of rehabilitation therapy addressing not only weakness but also organ damage problems of sepsis survivors.

Abstract
BACKGROUND/AIM Blunt chest trauma is one of the major injuries in multiply injured patients and is associated with an increased risk of acute respiratory distress syndrome (ARDS) and ventilator-associated pneumonia (VAP). Accidental hypothermia is a common accompaniment of multiply injured patients. The objective of this study was to analyze the influence of accidental hypothermia on pulmonary complications in multiply injured patients with blunt chest trauma. PATIENTS AND METHODS Multiply injured patients [injury severity score (ISS) ≥16] with severe blunt chest trauma [abbreviated injury scale of the chest (AISchest) ≥3] were analyzed. Hypothermia was defined as body core temperature <35°C. The primary endpoint was the development of ARDS and VAP. Propensity score matching was performed. RESULTS Data were analyzed for 238 patients, with a median ISS of 26 (interquartile range=12). A total of 67 patients (28%) were hypothermic on admission. Hypothermic patients were injured more severely (median ISS 34 vs. 24, p<0.001) and had a higher transfusion requirement (p<0.001). Their mortality rate was consequently increased (10% vs. 1%, p=0.002); After propensity score matching, the mortality rate was still higher (10% vs. 2%, p=0.046). However, hypothermia was not an independent predictor of mortality. Hypothermic patients had to be ventilated longer (p=0.02). However, there were no differences in occurrence of ARDS and VAP. Hypothermia was not identified as an independent predictor of ARDS and VAP. CONCLUSION Among multiply injured patients with severe blunt chest trauma, accidental hypothermia is not an independent predictor of ARDS and VAP and is more likely to be an accompaniment of injury severity and hemorrhage.

Abstract
Atrial fibrillation (AF) is by far the most frequent cardiac arrhythmia associated with sepsis and infections. Newly occurring AF due to infections is associated with a deterioration of the prognosis for acute events and also for the long-term prognosis of patients. The risk of developing AF during an infection depends on general (e.g. age, structural heart disease) as well as infection-specific risk factors (e.g. sepsis severity, vasopressor treatment). Current guidelines do not make specific recommendations on the treatment of infection-associated AF and very few prospective data are available. The use of beta blockers appears to be safe for both prevention and frequency control of AF even in patients requiring catecholamines. For specific antiarrhythmic treatment, the use of class I antiarrhythmic agents is conceivable as an alternative to the predominantly used amiodarone. Newly occurring AF within infections has long been considered a specific entity with a low risk of recurrence, so that only a small proportion of patients received long-term effective anticoagulation; however, data from large retrospective studies suggest significantly higher recurrence rates. Therefore, the question of whether this group of patients benefits from long-term effective anticoagulation and extended monitoring of arrhythmia should be the subject of future research.

Abstract
Background Sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection with a hospital mortality in excess of 40%. Along with insufficient and delayed empirical antimicrobial therapy, inappropriate antimicrobial exposure has been identified to negatively affect patient outcomes. Receipt of prolonged infusion (i.e. extended or continuous infusion) of piperacillin/tazobactam (TZP) improves antimicrobial exposure and is associated with reduced mortality in patients with sepsis. Using therapeutic drug monitoring (TDM) with dosing tailored to the altered pharmacokinetics of the individual patient to avoid under- and overdosing may be a further strategy to improve patient outcomes. This current trial will address the question whether a TDM-guided therapy with TZP administered by continuous infusion will result in a greater resolution of organ dysfunction and hence better clinical outcome compared to continuous infusion of the total daily dose of TZP without TDM. Methods The study is an investigator-initiated, multi-centre, parallel-group, single-blinded, randomised controlled trial. The trial will be conducted in several centres across Germany. Adult patients (aged ≥ 18 years) with severe sepsis or septic shock will be eligible for study participation. Participants will be randomly assigned to receive either TZP by continuous infusion guided by daily TDM of piperacillin (experimental group) or by continuous infusion without TDM guidance (total daily dose in normal renal function 13.5 g TZP) (control group). The pharmacokinetic (PK)/pharmacodynamic (PD) target will be 100% f T>4MIC (percentage of time during a dosing interval that the free [f] drug concentration exceeds 4 times the minimum inhibitory concentration). The primary efficacy endpoint is the change in mean total Sequential Organ Failure Assessment score from day 1 after randomisation until day 10 or discharge from the intensive care unit or death, whichever comes first. Secondary outcomes include mortality, clinical cure, microbiological cure, overall antibiotic use, individual components of the primary outcome, adverse events and analysis of PK and (PD) indices. Discussion This trial will assess for the first time whether continuous infusion of TZP guided by daily TDM in patients with sepsis will result in a greater resolution of organ dysfunction and hence better clinical outcome compared to continuous infusion without TDM.

Abstract
BACKGROUND The definition of sepsis has evolved over time, along with the clinical and scientific knowledge behind it. For years, sepsis was defined as a systemic inflammatory response syndrome (SIRS) in the presence of a documented or suspected infection. At present, sepsis is defined as a life-threatening organ dysfunction resulting from a dysregulated host response to infection. Even though sepsis is one of the leading causes of mortality in critically ill patients, and the World Health Organization (WHO) recognizes it as a healthcare priority, it still lacks an accurate diagnostic test. Determining the accuracy of interleukin-6 (IL-6) concentrations in plasma, which is proposed as a new biomarker for the diagnosis of sepsis, might be helpful to provide adequate and timely management of critically ill patients, and thus reduce the morbidity and mortality associated with this condition. OBJECTIVES To determine the diagnostic accuracy of plasma interleukin-6 (IL-6) concentration for the diagnosis of bacterial sepsis in critically ill adults. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, LILACS, and Web of Science on 25 January 2019. We screened references in the included studies to identify additional studies. We did not apply any language restriction to the electronic searches. SELECTION CRITERIA We included diagnostic accuracy studies enrolling critically ill adults aged 18 years or older under suspicion of sepsis during their hospitalization, where IL-6 concentrations were evaluated by serological measurement. DATA COLLECTION AND ANALYSIS Two review authors independently screened the references to identify relevant studies and extracted data. We assessed the methodological quality of studies using the Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) tool. We estimated a summary receiver operating characteristic (SROC) curve by fitting a hierarchical summary ROC (HSROC) non-linear mixed model. We explored sources of heterogeneity using the HSROC model parameters. We conducted all analyses in the SAS statistical software package and R software. MAIN RESULTS We included 23 studies (n = 4192) assessing the accuracy of IL-6 for the diagnosis of sepsis in critically ill adults. Twenty studies that were available as conference proceedings only are awaiting classification. The included participants were heterogeneous in terms of their distribution of age, gender, main diagnosis, setting, country, positivity threshold, sepsis criteria, year of publication, and origin of infection, among other factors. Prevalence of sepsis greatly varied across studies, ranging from 12% to 78%. We considered all studies to be at high risk of bias due to issues related to the index test domain in QUADAS-2. The SROC curve showed a great dispersion in individual studies accuracy estimates (21 studies, 3650 adult patients), therefore the considerable heterogeneity in the collected data prevented us from calculating formal accuracy estimates. Using a fixed prevalence of sepsis of 50% and a fixed specificity of 74%, we found a sensitivity of 66% (95% confidence interval 60 to 72). If we test a cohort 1000 adult patients under suspicion of sepsis with IL-6, we will find that 330 patients would receive appropriate and timely antibiotic therapy, while 130 patients would be wrongly considered to have sepsis. In addition, 370 out of 1000 patients would avoid unnecessary antibiotic therapy, and 170 patients would have been undiagnosed of sepsis. This numerical approach should be interpreted with caution due to the limitations described above. AUTHORS' CONCLUSIONS Our evidence assessment of plasma interleukin-6 concentrations for the diagnosis of sepsis in critically ill adults reveals several limitations. High heterogeneity of collected evidence regarding the main diagnosis, setting, country, positivity threshold, sepsis criteria, year of publication, and the origin of infection, among other factors, along with the potential number of misclassifications, remain significant constraints for its implementation. The 20 conference proceedings assessed as studies awaiting classification may alter the conclusions of the review once they are fully published and evaluated. Further studies about the accuracy of interleukin-6 for the diagnosis of sepsis in adults that apply rigorous methodology for conducting diagnostic test accuracy studies are needed. The conclusions of the review will likely change once the 20 studies pending publication are fully published and included.

Effects of the timing of administration of IgM- and IgA-enriched intravenous polyclonal immunoglobulins on the outcome of septic shock patients. Ann Intensive Care 2018; 8:122. [PMID: 30535962 PMCID: PMC6288102 DOI: 10.1186/s13613-018-0466-7] [Citation(s) in RCA: 28] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2018] [Accepted: 11/30/2018] [Indexed: 12/29/2022] Open
Abstract
BACKGROUND The administration of endovenous immunoglobulins in patients with septic shock could be beneficial and preparations enriched with IgA and IgM (ivIgGAM) seem to be more effective than those containing only IgG. In a previous study Berlot et al. demonstrated that early administration of ivIgGAM was associated with lower mortality rate. We studied a larger population of similar patients aiming either to confirm or not this finding considering also the subgroup of patients with septic shock by multidrug-resistant (MDR) pathogens. METHODS Adult patients with septic shock in intensive care unit (ICU) treated with ivIgGAM from August 1999 to December 2016 were retrospectively examined. Collected data included the demographic characteristics of the patients, the diagnosis at admission, SOFA, SAPS II and Murray Lung Injury Score (LIS), characteristics of the primary infection, the adequacy of antimicrobial therapy, the delay of administration of ivIgGAM from the ICU admission and the outcome at the ICU discharge. Parametric and nonparametric tests and logistic regression were used for statistic analysis. RESULTS During the study period 107 (30%) of the 355 patients died in ICU. Survivors received the ivIgGAM earlier than nonsurvivors (median delay 12 vs 14 h), had significantly lower SAPS II, SOFA and LIS at admission and a lower rate of MDR- and fungal-related septic shock. The appropriateness of the administration of antibiotics was similar in survivors and nonsurvivors (84 vs 79%, respectively, p: n.s). The delay in the administration of ivIgGAM from the admission was associated with in-ICU mortality (odds ratio per 1-h increase = 1.0055, 95% CI 1.003-1.009, p < 0.001), independently of SAPS II, LIS, cultures positive for MDR pathogens or fungi and onset of septic shock. Only 46 patients (14%) had septic shock due to MDR pathogens; 21 of them (46%) died in ICU. Survivors had significantly lower SAPS II, SOFA at admission and delay in administration of ivIgGAM than nonsurvivors (median delay 18 vs 66 h). Even in this subgroup the delay in the administration of ivIgGAM from the admission was associated with an increased risk of in-ICU mortality (odds ratio 1.007, 95% CI 1.0006-1.014, p = 0.048), independently of SAPS II. CONCLUSIONS Earlier administration of ivIgGAM was associated with decreased risk of in-ICU mortality both in patients with septic shock caused by any pathogens and in patients with MDR-related septic shock.

Abstract
Purpose Sepsis contributes considerably to global morbidity and mortality, while reasons for its increasing incidence remain unclear. We assessed risk adjusted secular trends in sepsis and infection epidemiology in Germany. Methods Retrospective cohort study using nationwide German hospital discharge data. We assessed incidence, outcomes and trends of hospital-treated sepsis and infections between 2010 and 2015. Sepsis was identified by explicit ICD-10 sepsis codes. As sensitivity analysis, results were compared with sepsis cases identified by implicit sepsis coding (combined infection and organ dysfunction codes). Results Among 18 664 877 hospital admissions in 2015, 4 213 116 (22.6%) patients had at least one infection code. There were 320 198 patients that had explicit sepsis codes including 136 542 patients with severe sepsis and septic shock; 183 656 patients were coded as sepsis without organ dysfunction. For patients with explicitly coded sepsis (including severe sepsis), or with severe sepsis alone, mortality rates over the period 2010–2015 decreased from 26.6 to 23.5%, and from 47.8 to 41.7%, respectively. Conclusions Sepsis and infection remain significant causes of hospital admission and death in Germany. Sepsis-related mortality is higher and has declined to a lesser degree than in other high-income countries. Although infection rates steadily increased, the observed annual increase of sepsis cases seems to result, to a considerable degree, from improved coding of sepsis.

Abstract
BACKGROUND Atrial fibrillation is the most common new onset arrhythmia in patients hospitalized with sepsis; however, there are no specific treatment guidelines and the ideal therapeutic approaches still remain unclear. OBJECTIVES To begin with the current state of knowledge concerning the underling mechanisms, the incidence and prognostic impact of new onset atrial fibrillation during sepsis are presented. Then a possible therapeutic algorithm for the special situation of sepsis is derived with respect to the currently existing atrial fibrillation guidelines. Finally necessary future research topics are outlined. MATERIAL ANS METHODS A systematic literature search was conducted in MEDLINE. All publications (reviews and studies) relevant for the summary of the current knowledge regarding new onset atrial fibrillation in septic patients were included. RESULTS The underlying patchomechanism is primarily systemic inflammation. Approximately 8% of patients with sepsis and more than 20% of patients with septic shock develop new onset atrial fibrillation. The occurrence of atrial fibrillation is associated with increased morbidity and mortality. The necessity of rhythm control therapy is dependent on the hemodynamic stability. The success rate of electrical cardioversion can be increased by the administration of amiodarone. The necessity of systemic anticoagulation is based on the individual risk of thromboembolism. CONCLUSION Further research is needed to unveil the optimal therapeutic strategies for patients with new onset atrial fibrillation during sepsis.

Abstract
INTRODUCTION Administrative data are used to generate estimates of sepsis epidemiology and can serve as source for quality indicators. Aim was to compare estimates on sepsis incidence and mortality based on different ICD-code abstraction strategies and to assess their validity for sepsis case identification based on a patient sample not pre-selected for presence of sepsis codes. MATERIALS AND METHODS We used the national DRG-statistics for assessment of population-level sepsis incidence and mortality. Cases were identified by three previously published International Statistical Classification of Diseases (ICD) coding strategies for sepsis based on primary and secondary discharge diagnoses (clinical sepsis codes (R-codes), explicit coding (all sepsis codes) and implicit coding (combined infection and organ dysfunction codes)). For the validation study, a stratified sample of 1120 adult patients admitted to a German academic medical center between 2007-2013 was selected. Administrative diagnoses were compared to a gold standard of clinical sepsis diagnoses based on manual chart review. RESULTS In the validation study, 151/937 patients had sepsis. Explicit coding strategies performed better regarding sensitivity compared to R-codes, but had lower PPV. The implicit approach was the most sensitive for severe sepsis; however, it yielded a considerable number of false positives. R-codes and explicit strategies underestimate sepsis incidence by up to 3.5-fold. Between 2007-2013, national sepsis incidence ranged between 231-1006/100,000 person-years depending on the coding strategy. CONCLUSIONS In the sample of a large tertiary care hospital, ICD-coding strategies for sepsis differ in their accuracy. Estimates using R-codes are likely to underestimate the true sepsis incidence, whereas implicit coding overestimates sepsis cases. Further multi-center evaluation is needed to gain better understanding on the validity of sepsis coding in Germany.

Abstract
Bone sialoprotein (BSP), a member of the SIBLINGs (for Small Integrin-Binding LIgand, N-linked Glycoproteins) family, has recently be associated to inflammatory and infectious diseases. We therefore measured BSP concentrations in 136 patients at admission to the intensive care unit (ICU) and 3 days of ICU. BSP levels were compared to 36 healthy blood donors and correlated to clinical data. In these analysis, BSP serum levels were strongly elevated at the time point of admission to the ICU when compared to healthy controls. Moreover BSP concentrations were significantly elevated after 3 days of treatment on the intensive care unit. A further increase in BSP levels was detected in patients with higher APACHE-II-scores and in patients with septic disease. While in most patients, BSP levels decreased during the first three days of treatment on a medical ICU, patients with persistently elevated BSP levels displayed an unfavorable outcome. In these patients, persistently elevated BSP concentrations were a superior predictor of mortality than established indicators of patient´ prognosis such as the SAPS2 or the APACHE-II score. In summary, our data argue for a novel utility for BSP as a biomarker in patients treated on a medical ICU.

Efficacy of introducing a checklist to reduce central venous line associated bloodstream infections in the ICU caring for adult patients. BMC Infect Dis 2018; 18:267.

Abstract
Background Central line-associated bloodstream infections (CLABSI) are a major source of sepsis in modern intensive care medicine. Some years ago bundle interventions have been introduced to reduce CLABSI. The use of checklists may be an additional tool to improve the effect of these bundles even in highly specialized institutions. In this study we investigate if the introduction of a checklist reduces the frequency of CLABSI. Methods During the study period from October 2011 to September 2012, we investigated the effect of implementing a checklist for the placement of central venous lines (CVL). Patients were allocated either to the checklist group or to the control group, roughly in a 1:2 ratio. The frequency of CLABSI was compared between the two groups. Results During the study period 4416 CVL were inserted; 1518 in the checklist group and 2898 in the control group. The use of the checklist during CVL placement resulted in a lower CLABSI frequency. The incidence in the checklist group was 3.8 per 1000 catheter days as compared to 5.9 per 1000 catheter days in the control group (IRR = 0.57; p = 0.001). The use of the checklist also reduced the frequency of catheter colonisation significantly, 36.3 per 1000 catheter days in the checklist group vs 21.2 per 1000 catheter days in the control group, respectively (IRR = 0.58; p < 0.001). Conclusion The introduction of a checklist to improve the adherence to hygiene standards while placement of central venous lines reduced the frequency of infections significantly.

Early immune anergy towards recall antigens and mitogens in patients at onset of septic shock. Sci Rep 2018; 8:1754.

Abstract
The pathology of sepsis is typically characterized by an infection and excessive initial inflammation including a cytokine storm, followed by a state of immune suppression or paralysis. This classical view of a two peak kinetic immune response is currently controversially discussed. This study was a sub-study of the randomized clinical Trial SISPCT registered with www.clinicaltrials.gov (NCT00832039, Registration date: 29/01/2009). Blood samples from 76 patients with severe sepsis and septic shock were incubated for 48 h at 37 °C in vitro with bacterial or fungal recall-antigens or specific mitogen antigens within 24 hours of sepsis onset. Recall-antigen stimulation led to a severe dampening of normal cytokine release. This immunologic anergy was similarly observed after mitogen stimulation. Moreover, patients under hydrocortisone therapy or with lowered arterial oxygen tension had further reductions in cytokine levels upon B- and T-cell mitogen stimulation. This investigation reveals an early onset of immunoparalysis during sepsis. This immune incompetence in mounting an adequate response to further infections includes previously sensitized pathogens, as seen with recall-antigens. Also, the immune-suppressive role of hydrocortisone and low PaO2 is highlighted. Aside from early broad-spectrum antimicrobial therapy, our findings reinforce the need for maximal immunological support and protection against further infections at the onset of sepsis.

Abstract
Background Severe sepsis and septic shock remain a major challenge, even in modern intensive care. In Germany, about 68,000 patients die annually because of septic diseases, characterized by a complex systemic inflammatory response. Causal treatment of the underlying infection is essential for successful management of sepsis, but the course can be positively influenced by supportive and adjuvant measures. The cholinergic anti-inflammatory pathway (CAP) represents a new approach to adjunctive therapy of septic diseases and can be pharmacologically activated by the acetylcholinesterase inhibitor physostigmine (Anticholium®). Promising effects can be found in several in vitro and in vivo models of sepsis, such as a reduction in pro-inflammatory cytokines and improved survival. Methods Anticholium® per Se is a randomized, double-blind, placebo-controlled, monocentric trial to assess whether the CAP can be transferred from bench to bedside. In this pilot study, 20 patients with perioperative sepsis and septic shock as a result of intra-abdominal infection are enrolled. According to randomization, participants are treated with physostigmine salicylate (verum group) or 0.9% sodium chloride (placebo group) for up to 5 days. The mean Sequential Organ Failure Assessment (SOFA) score during treatment and subsequent intensive care of up to 14 days is used as surrogate outcome (primary endpoint). Secondary outcome measures include 30- and 90-day mortality. An embedded pharmacokinetics and pharmacodynamics study investigates plasma concentrations of physostigmine and its metabolite eseroline. Further analyses will contribute to our understanding of the role of various cytokines in the pathophysiology of human sepsis. A computer-generated list is used for block randomization. Discussion This randomized, controlled, monocentric trial investigates for the first time the adjunctive use of physostigmine (Anticholium®) in patients with perioperative sepsis and septic shock and may be a pivotal step toward the clinical use in this indication.

Abstract
INTRODUCTION An increasing number of patients survive sepsis; however, we lack valid data on the long-term impact on morbidity from prospective observational studies. Therefore, we designed an observational cohort to quantify mid-term and long-term functional disabilities after intensive care unit (ICU)-treated sepsis. Ultimately, findings for the Mid-German Sepsis Cohort (MSC) will serve as basis for the implementation of follow-up structures for patients with sepsis and help to increase quality of care for sepsis survivors. METHODS AND ANALYSIS All patients surviving ICU-treated sepsis are eligible and are recruited from five study centres in Germany (acute care hospital setting in Jena, Halle/Saale, Leipzig, Bad Berka, Erfurt; large long-term acute care hospital and rehabilitation setting in Klinik Bavaria Kreischa). Screening is performed by trained study nurses. Data are collected on ICU management of sepsis. On written informed consent provided by patients or proxies, follow-up is carried out by trained research staff at 3, 6 and 12 months and yearly thereafter. The primary outcome is functional disability as assessed by (instrumental) activities of daily living. Other outcomes cover domains like mortality, cognitive, emotional and physical impairment, and resource use. The estimated sample size of 3000 ICU survivors is calculated to allow detection of relevant changes in the primary outcome in sepsis survivors longitudinally. ETHICS AND DISSEMINATION The study is conducted according to the current version of the Declaration of Helsinki and has been approved by four local/federal responsible institutional ethics committees and by the respective federal data protection commissioners. Results of MSC will be fed back to the patients and published in peer-reviewed journals. TRIAL REGISTRATION NUMBER German Clinical Trials Registry DRKS00010050.

Abstract
Sepsis is a serious medical condition that occurs in 30% of patients in intensive care units (ICUs). Early detection of sepsis is key to prevent its progression to severe sepsis and septic shock, which can cause organ failure and death. Diagnostic criteria for sepsis are nonspecific and hinder a timely diagnosis in patients. Therefore, there is currently a large effort to detect biomarkers that can aid physicians in the diagnosis and prognosis of sepsis. Mass spectrometry is often the method of choice to detect metabolomic and proteomic changes that occur during sepsis progression. These "omics" strategies allow for untargeted profiling of thousands of metabolites and proteins from human biological samples obtained from septic patients. Differential expression of or modifications to these metabolites and proteins can provide a more reliable source of diagnostic biomarkers for sepsis. Here, we focus on the current knowledge of biomarkers of sepsis and discuss the various mass spectrometric technologies used in their detection. We consider studies of the metabolome and proteome and summarize information regarding potential biomarkers in both general and neonatal sepsis.

Abstract
Background Appropriate and timely recognition of sepsis is a prerequisite for starting goal-directed therapy bundles. We analyzed the appropriateness of sepsis recognition and documentation with regard to adequacy of therapy and outcome in an internal medicine emergency department (ED). Methods This study included 487 consecutive patients ≥18 years of age who presented to a university hospital ED during a 4-week period. Clinical, laboratory, and follow-up data were acquired independently from documentation by ED physicians. The study team independently rated quality of sepsis classification (American College of Chest Physicians/Society of Critical Care Medicine definitions), diagnostic workup, and guideline-adherent therapy in the ED. Results Of 487 included patients, 110 presented because of infection. Of those, 54 patients matched sepsis criteria, including 20 with organ damage and thus severe sepsis, as rated by the study team. Sepsis was not recognized in 32 of these 54 cases (59%). Multivariate binary logistic regression analysis revealed that higher systolic blood pressure (p <0.05), the ability to stand (p <0.01) and a low number of documented vital signs in the ED discharge letter (p < 0.05) were independent predictors of missed sepsis. Surprisingly, adequate detection of the septic focus (81 vs. 93%, p = 0.17), appropriate fluid administration (86 vs. 87%, p = 0.39), and guideline-adherent antibiotic regimen (95 vs. 100%, p = 0.42) did not differ between cases of recognized and unrecognized sepsis, respectively. Non-recognition affected neither death-censored length of hospital stay (median 7.63 d vs. 7.13 d, p = 0.42) nor a combined endpoint of death or ICU admission to (9 vs. 12%, p = 0.55). Conclusions Non-recognition of sepsis in ED patients with serious infections who formally meet organizational sepsis definitions seems to have no deleterious impact on initial therapy adequacy.

Abstract
The secretion of antimicrobial compounds is an ancient mechanism with clear survival benefits for microbes competing with other microorganisms. Consequently, mechanisms that confer resistance are also ancient and may represent an underestimated reservoir in environmental bacteria. In this context, β-lactamases (BLs) are of great interest due to their long-term presence and diversification in the hospital environment, leading to the emergence of Gram-negative pathogens that are resistant to cephalosporins (extended spectrum BLs = ESBLs) and carbapenems (carbapenemases). In the current study, protein sequence databases were used to analyze BLs, and the results revealed a substantial number of unknown and functionally uncharacterized BLs in a multitude of environmental and pathogenic species. Together, these BLs represent an uncharacterized reservoir of potentially transferable resistance genes. Considering all available data, in silico approaches appear to more adequately reflect a given resistome than analyses of limited datasets. This approach leads to a more precise definition of BL clades and conserved motifs. Moreover, it may support the prediction of new resistance determinants and improve the tailored development of robust molecular diagnostics.

Impact of Pre-Analytical Time on the Recovery of Pathogens from Blood Cultures: Results from a Large Retrospective Survey. PLoS One 2017; 12:e0169466. [PMID: 28046040 PMCID: PMC5207733 DOI: 10.1371/journal.pone.0169466] [Citation(s) in RCA: 25] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2016] [Accepted: 12/16/2016] [Indexed: 12/20/2022] Open
Abstract
BACKGROUND Prompt identification of bloodstream pathogens is essential for optimal management of patients. Significant changes in analytical methods have improved the turnaround time for laboratory diagnosis. Less attention has been paid to the time elapsing from blood collection to incubation and to its potential effect on recovery of pathogens. We evaluated the performance of blood cultures collected under typical hospital conditions in relation to the length of their pre-analytical time. METHODS We carried out a large retrospective study including 50,955 blood cultures collected, over a 30-month period, from 7,035 adult septic patients. Cultures were accepted by the laboratory only during opening time (Mon-Fri: 8am-4pm; Sat: 8am-2pm). Samples collected outside laboratory hours were stored at room temperature at clinical wards. All cultures were processed by automated culture systems. Day and time of blood collection and of culture incubation were known for all samples. RESULTS A maximum pre-analytical interval of 2 hours is recommended by guidelines. When the laboratory was open, 57% of cultures were processed within 2 h. When the laboratory was closed, 4.9% of cultures were processed within 2 h (P<0.001). Samples collected when the laboratory was closed showed pre-analytical times significantly longer than those collected when laboratory was open (median time: 13 h and 1 h, respectively, P<0.001). The prevalence of positive cultures was significantly lower for samples collected when the laboratory was closed compared to open (11% vs 13%, P<0.001). The probability of a positive result decreased of 16% when the laboratory was closed (OR:0.84; 95%CI:0.80-0.89, P<0.001). Further, each hour elapsed from blood collection to incubation resulted associated with a decrease of 0.3% (OR:0.997; 95%CI:0.994-0.999, P<0.001) in the probability of a positive result. DISCUSSION Delayed insertions of cultures into automated systems was associated with lower detection rates, with potentially important consequences for patients. In each hospital setting the logistic factors able to shorten pre-analytical time should be carefully investigated and specifically targeted.

Abstract
Postoperative peritonitis is still a life-threatening complication after abdominal surgery and approximately 10,000 patients annually develop postoperative peritonitis in Germany. Early recognition and diagnosis before the onset of sepsis has remained a clinical challenge as no single specific screening test is available. The aim of therapy is a rapid and effective control of the source of infection and antimicrobial therapy. After diagnosis of diffuse postoperative peritonitis surgical revision is usually inevitable after intestinal interventions. Peritonitis after liver, biliary or pancreatic surgery is managed as a rule by means of differentiated therapy approaches depending on the severity.

Abstract
BACKGROUND Sepsis is among the most common causes of death in Germany. Urosepsis accounts for 9-31% of all cases and has a mortality of 20-40%, which is low compared with that of sepsis in general. As the population ages, the incidence of urosepsis is likely to rise. METHODS Review of pertinent articles and guidelines retrieved by a selective search in PubMed. RESULTS Enterobacteria and Gram-positive organisms are the pathogens that most commonly cause urosepsis. The diagnosis can and must be made early on the basis of the typical clinical features, altered vital signs, and laboratory abnormalities, so that timely treatment can be initiated. 80% of cases are due to obstructive uropathy. The diagnostic evaluation includes physical examination, blood cultures, urinalysis, procalcitonin measurement, and ultrasonography. In one study, each additional hour of delay in the treatment of urosepsis with antibiotics was found to lower the survival rate by 7.6%. Antibiotics should be chosen in consideration of local resistance patterns and the expected pathogen spectrum. CONCLUSION Urologists, intensive care specialists, and microbiologists should all be involved in the interdisciplinary treatment of urosepsis. Patients' outcomes have improved recently, probably because of the frequent use of minimally invasive treatments to neutralize foci of infection. New biomarkers and new treatments still need to be validated in multicenter trials.

Abstract
Here, we present a case of a tracheal fistula due to an anastomotic insufficiency following abdominothoracic esophageal resection. Despite immediate discontinuity resection, the tracheal fistula could not be surgically closed, resulting in incomplete control of the source of infection and an alternative treatment concept in the form of interventional fistula closure using a Y-tracheal stent. However, owing to existing severe acute respiratory distress syndrome (ARDS), which is associated with a considerable risk of peri-interventional hypoxia, a temporary bridging concept using venovenous extracorporeal membrane oxygenation (ECMO) was implemented successfully.

Li S, Rong H, Guo Q, Chen Y, Zhang G, Yang J. Serum procalcitonin levels distinguish Gram-negative bacterial sepsis from Gram-positive bacterial and fungal sepsis. JOURNAL OF RESEARCH IN MEDICAL SCIENCES 2016; 21:39. [PMID: 27904585 PMCID: PMC5122113 DOI: 10.4103/1735-1995.183996] [Citation(s) in RCA: 45] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/14/2015] [Revised: 01/18/2016] [Accepted: 03/29/2016] [Indexed: 12/26/2022]
Abstract
BACKGROUND Serum procalcitonin (PCT) levels differ in patients with bacterial or fungal infections and are significantly elevated in patients with Gram-negative bacteremia. We evaluated the diagnostic accuracy of different inflammatory markers to discriminate sepsis caused by different pathogens. MATERIALS AND METHODS We included 328 episodes of bacteremia from 292 patients with sepsis and 31 patients with suspected sepsis in this study. Medical records of patients who had bacteremia caused by Gram-negative bacteria (Gram-negative), Gram-positive bacteria (Gram-positive) or fungi were reviewed, and information about PCT and other inflammatory markers was recorded. The diagnostic performance of inflammatory markers was calculated via receiver operating characteristic (ROC) curves. RESULTS Serum PCT levels in Gram-negative, Gram-positive, and fungal sepsis were 7.47 (interquartile range [IQR]: 1.09-41.26) ng/mL, 0.48 (IQR: 0.15-2.16) ng/mL, and 0.60 (IQR: 0.14-2.06) ng/mL, respectively (P < 0.001). ROC analysis revealed an optimal cut-off value of 2.44 ng/mL for PCT in discriminating Gram-negative sepsis from Gram-positive sepsis, which yielded a sensitivity of 68.4% and a specificity of 77.1%. An optimal cut-off value of 3.11 ng/mL for PCT in discriminating Gram-negative sepsis from fungal sepsis, led to a sensitivity of 63.9% and specificity of 93.3%. Neither PCT nor other inflammatory markers could be used to distinguish between Gram-positive and fungal sepsis. CONCLUSION Serum PCT levels were significantly higher in patients with Gram-negative sepsis than in those with Gram-positive or fungal sepsis. PCT is a potential sensitive biomarker for distinguishing Gram-negative sepsis from Gram-positive and fungal sepsis.

Abstract
BACKGROUND Stress hyperglycaemia (SHG) is a common complication in sepsis associated with poor outcome. Chemerin is an adipocytokine associated with inflammation and impaired glucose homeostasis in metabolic diseases such as type 2 diabetes (T2D). We aimed to investigate how alterations of circulating chemerin levels and corresponding visceral adipose tissue (VAT) expression are linked to glucose metabolism and prognosis in sepsis. METHODS Clinical data and tissue samples were taken from a cross-sectional study including control, T2D and sepsis patients, all undergoing laparotomy. A second independent patient cohort of patients with sepsis was included to evaluate associations with prognosis. This was complemented by a murine model of peritoneal infection and a high-fat diet. We analysed circulating chemerin by enzyme-linked immunosorbent assay and VAT messenger RNA (mRNA) expression by real-time polymerase chain reaction. RESULTS Circulating chemerin was increased in sepsis 1.69-fold compared with controls (p = 0.012) and 1.47-fold compared with T2D (p = 0.03). Otherwise, chemerin VAT mRNA expression was decreased in patients with sepsis (p = 0.006) and in septic diabetic animals (p = 0.009). Circulating chemerin correlated significantly with intra-operative glucose (r = 0.662; p = 0.01) and in trend with fasting glucose (r = 0.528; p = 0.052). After adjusting for body mass index or haemoglobin A1c, chemerin correlated in trend with insulin resistance evaluated using the logarithmised homeostasis model assessment of insulin resistance (r = 0.539, p = 0.071; r = 0.553, p = 0.062). Chemerin was positively associated with Acute Physiology and Chronic Health Evaluation II score in patients with sepsis (p = 0.036) and with clinical severity in septic mice (p = 0.031). In an independent study population, we confirmed association of chemerin with glucose levels in multivariate linear regression analysis (β = 0.556, p = 0.013). In patients with sepsis with SHG, non-survivors had significantly lower chemerin levels than survivors (0.38-fold, p = 0.006), while in patients without SHG, non-survivors had higher chemerin levels, not reaching significance (1.64-fold, p = 0.089). No difference was apparent in patients with pre-existing T2D (p = 0.44). CONCLUSIONS We show, for the first time to our knowledge, that chemerin is increased in sepsis and that it associates with impaired glucose metabolism and survival in these patients. It could be further evaluated as a biomarker to stratify mortality risk of patients with SHG.

Med Klin Intensivmed Notfmed 2015; 112:30-37. [PMID: 26681382 DOI: 10.1007/s00063-015-0121-0] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2015] [Revised: 08/30/2015] [Accepted: 09/30/2015] [Indexed: 01/03/2023]
Abstract
INTRODUCTION Endogenous immunoglobulins (Igs) are of fundamental importance in the host defense after microbial infections. However, the therapeutic administration of intravenous IgG (IVIgG) has not yet been shown to improve clinical outcomes in patients suffering from sepsis, and in the case of IgM-containing preparations (IVIgGMA) the positive evidence is only weak. Recently published studies implicate that Ig levels on admission could have an impact on the patient's response to IVIg treatment and on outcomes of critically ill patients. METHODS In this noninterventional study, the serum levels of IgG, IgM, and IgA were determined in 340 medical patients on ICU admission, and clinical outcomes were prospectively recorded (ICU mortality, need for renal replacement therapy (RRT), need for mechanical ventilation, substitution of coagulation factors, and amount of red cell transfusions). Patients were prospectively grouped according to their main reason for ICU admission (sepsis, respiratory failure, cardiovascular diseases, acute renal failure, postoperative condition, state after cardiopulmonal resuscitation, gastrointestinal diseases, and others). RESULTS AND DISCUSSION There was no correlation between the Ig levels on admission and ICU mortality neither in the total cohort of medical ICU patients nor in any prespecified subgroup. However, in a logistic regression model that was adjusted for APACHE II score on admission, an increase in serum IgG was associated with a reduced need for mechanical ventilation in patients suffering from cardiovascular disease. On the other hand, in patients suffering from sepsis, an increased level of IgM was linked to an increased administration of coagulation factors. CONCLUSION Our data do not support the hypothesis that serum levels of immunoglobulins are linked to mortality in medical ICU patients.

[PMID: 26555619 DOI: 10.1007/s00063-015-0111-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2015] [Revised: 08/02/2015] [Accepted: 09/04/2015] [Indexed: 12/29/2022]
Abstract
BACKGROUND Appropriate fluid resuscitation is a fundamental aspect for the hemodynamic management of septic shock patients and should ideally be achieved before vasopressors and positive inotropic substances are administered. The development of hemodynamic monitoring has revealed that in some cases patients had been improperly treated with high-dose catecholamines for initially insufficient fluid resuscitation. The aim of this study was to show that in some cases it is possible to actively reduce catecholamines by a volume challenge adapted according to the individual patient needs. MATERIAL AND METHODS In this retrospective observational study 29 patients with septic shock in a surgical intensive care unit (ICU) at a university hospital (17 male, 12 female, mean age 71 ± 10 years) on high-dose catecholamines (median values norepinephrine 0.204 µg/kg body weight/min, dobutamine 3.876 µg/kg/min and epinephrine 0.025 µg/kg/min, ranging up to 0.810 µg/kg/min, 22.222 µg/kg/min and 0.407 µg/kg/min in 28, 20 and 17 patients, respectively) were analyzed. The extremities of the patients were initially cold with a mottled marbled appearance whereas the mean arterial pressure (MAP) was ≥ 65 mmHg. The median central venous pressure (CVP) was 17 mmHg (range 55-34 mmHg) and the mean lactate concentration was 2.78 mmol/l (range 0.93-10.67 mmol/l). The standard therapy concept consisted of a forced volume challenge combined with active reduction of catecholamines to achieve an adequate fluid loading status, guided by the passive leg raising test (PLR), clinical signs and in 19 cases by hemodynamic monitoring (pulmonary artery catheter Vigilance II(™) n = 10, FloTrac(™), Vigileo(™) n = 9 and PreSep(™) n = 5; Edwards Life Sciences). The forced volume challenge was stopped after clinical improvement with rewarmed extremities, increasing diuresis volumes and lack of improvement by PLR. RESULTS Catecholamine doses could be significantly reduced in all patients: norepinephrine to 0 µg/kg/min, dobutamine to 1.852 µg/kg/min and epinephrine to 0 µg/kg/min (up to 0.133 µg/kg/min, 6.289 µg/kg/min and 0.091 µg/kg/min, respectively, p < 0.05 Wilcoxon signed rank test). Volume challenge test: + 4,500 ml Ringer solution (range 0-24,000 ml) and 1,000 ml hydroxyethyl starch (range 0-2,500 ml) and mean fluid balance + 6,465 ml (range + 2,040 ml to + 27,255 ml). The median weaning time from catecholamines was 12 h (range 4-43 h). After treatment all patients showed rewarmed extremities and a decrease in mean lactate levels from 2.78 mmol/l (range 0.93-10.67 mmol/l) to 2.05 mmol/l (range 0.7-5.4 mmol/l). The measured hemodynamic constellations showed clear interindividual differences but no cardiac deterioration occurred. The median oxygenation index (paO2/FiO2) showed a statistically insignificant change from 264 mmHg (range 75-418 mmHg) to 250 mmHg (range 120-467 mmHg). Of the patients 20 survived and 9 died. CONCLUSION It is possible to wean a substantial proportion of septic shock patients from high-dose catecholamines in combination with a needs-adapted forced volume challenge test. The importance of appropriate fluid loading prior to the use of high catecholamine doses should be a main subject of discussion in patients with severe septic shock and was confirmed in this study. This should be oriented to clinical and if possible, hemodynamic parameters and should not be underestimated.

Abstract
OBJECTIVE To detect connections between parameters of ventilation and outcomes of cardiac intensive care patients. DESIGN AND SETTING Noninterventional study. Between 05/11 and 05/12 all patients with acute heart failure and post cardiopulmonary resuscitation were registered. Lung protective ventilation was defined as peak inspiratory pressure (PIP) < 30 mmHg and tidal volume (Vt) < = 6 ml/kg. RESULTS In total, 129 patients were included in the study, 68.2 % male, age 67.9 ± 13.4 years, weight 71.4 ± 37.2 kg, predictive body weight 66.9 ± 8.8 kg, mortality 47.3 %. Lung protective ventilated patients at day 1: 17.3 % with a significant difference between surviving and nonsurviving patients (24.1 % vs. 9.6 %; p < 0.05). Logistic regression models showed a strong connection between PIP and survival (odds ratio 1.13; p < 0.05). Vt showed no significant influence on survival. CONCLUSION Our data recommends a strict observance of a low PIP for cardiac intensive care patients, whereas Vt seems to be of secondary importance.

Abstract
PURPOSE Infections and subsequent septicemia are major complications in neutropenic patients with hematological malignancies. Here, we identify biomarker candidates for the early detection of an infectious origin, and monitoring of febrile neutropenia (FN). METHODS Proteome, metabolome, and conventional biomarkers from 20 patients with febrile neutropenia without proven infection (FNPI) were compared to 28 patients with proven infection, including 17 patients with bacteremia. RESULTS Three peptides (mass to charge ratio 1017.4-1057.3; p-values 0.011-0.024), six proteins (mass to charge ratio 6881-17,215; p-values 0.002-0.004), and six phosphatidylcholines (p-values 0.007-0.037) were identified that differed in FNPI patients compared to patients with infection or bacteremia. Seven of these marker candidates discriminated FNPI from infection at fever onset with higher sensitivity and specificity (ROC-AUC 0.688-0.824) than conventional biomarkers i.e., procalcitonin, C-reactive protein, or interleukin-6 (ROC-AUC 0.535-0.672). In a post hoc analysis, monitoring the time course of four lysophosphatidylcholines, threonine, and tryptophan allowed for discrimination of patients with or without resolution of FN (ROC-AUC 0.648-0.919) with higher accuracy compared to conventional markers (ROC-AUC 0.514-0.871). CONCLUSIONS Twenty-one promising biomarker candidates for the early detection of an infectious origin or for monitoring the course of FN were found which might overcome known shortcomings of conventional markers.

Persistently elevated osteopontin serum levels predict mortality in critically ill patients. CRITICAL CARE : THE OFFICIAL JOURNAL OF THE CRITICAL CARE FORUM 2015; 19:271. [PMID: 26111529 PMCID: PMC4490692 DOI: 10.1186/s13054-015-0988-4] [Citation(s) in RCA: 39] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/23/2015] [Accepted: 06/12/2015] [Indexed: 01/09/2023]
Abstract
Introduction Inflammatory, autoimmune and metabolic disorders have been associated with alterations in osteopontin (OPN) serum levels. Furthermore, elevated serum levels of OPN were reported from a small cohort of patients with sepsis. We therefore analyzed OPN serum concentrations in a large cohort of critically ill medical patients. Methods A total of 159 patients (114 with sepsis, 45 without sepsis) were studied prospectively upon admission to the medical intensive care unit (ICU) as well as after 3 days of ICU treatment and compared to 50 healthy controls. Clinical data, various laboratory parameters as well as investigational inflammatory cytokine profiles were assessed. Patients were followed for approximately 1 year. Results We found significantly elevated serum levels of OPN at admission to the ICU and after 3 days of treatment in critically ill patients compared to healthy controls. OPN concentrations were related to disease severity and significantly correlated with established prognosis scores and classical as well as experimental markers of inflammation and multi-organ failure. In the total cohort, OPN levels decreased from admission to day 3 of ICU treatment. However, persistently elevated OPN levels at day 3 of ICU treatment were a strong independent predictor for an unfavorable prognosis, with similar or better diagnostic accuracy than routinely used markers of organ failure or prognostic scoring systems such as SAPS2 or APACHE II score. Conclusions Persistently elevated OPN serum concentrations are associated with an unfavourable outcome in patients with critical illness, independent of the presence of sepsis. Besides a possible pathogenic role of OPN in critical illness, our study indicates a potential value for OPN as a prognostic biomarker in critically ill patients during the early course of ICU treatment.

Prospective evaluation of regional oxygen saturation to estimate central venous saturation in sepsis. J Clin Monit Comput 2015; 29:443-53. [PMID: 25757404 DOI: 10.1007/s10877-015-9683-x] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2014] [Accepted: 02/27/2015] [Indexed: 01/01/2023]
Abstract
Current treatment guidelines for sepsis claim an early goal-directed hemodynamic optimization including fluid resuscitation, use of vasopressors and inotropic agents. We investigated the correlation between the prominent treatment goal central venous saturation (ScvO2) and the frontal and the thenar regional oxygen saturation (rSO2) measured by near infrared spectroscopy. Secondary, we examined the value of ScvO2, lactate levels and rSO2 as surrogate markers of an impaired tissue oxygenation for outcome prediction in sepsis. This prospective, observational study was performed at the surgical intensive care unit of the University Hospital Giessen. A total of 50 patients with sepsis, severe sepsis or septic shock were included. ScvO2, rSO2 and lactate were measured at sepsis diagnosis (baseline), 24 and 48 h, thereafter. We investigated the predictive value of frontal and thenar rSO2 for a decreased SvcO2 under 70%. For survivor and non-survivors ScvO2, rSO2 and lactate were analysed. Patients with ScvO2 >70% showed a trend to higher levels of fontal rSO2 (62.81 ± 8.06 vs. 53.54 ± 15.48; p = 0.058). ROC-analysis revealed a minor prediction of a decreased ScvO2 by frontal rSO2 levels at baseline (AUC = 0.687; 95% CI 0.511-0.863; p = 0.047). Combined measurements of lactate and ScvO2 showed significantly elevated mortality for patients with ScvO2 ≥70% and lactate levels ≥2.5 mmol/l (log rank test p = 0.004). In the group with ScvO2 <70% and lactate levels <2.5 mmol/l no patients died during the observation period. Frontal rSO2 correlates with ScvO2 but both frontal and thenar rSO2 do not exactly discriminate between patients with high or low ScvO2 in sepsis. The combination of elevated lactate >2.5 mmol/l and ScvO2 >70 % is highly associated with poor outcome in ICU patients with sepsis, severe sepsis and septic shock.

Different duration strategies of perioperative antibiotic prophylaxis in adult patients undergoing cardiac surgery: an observational study. J Cardiothorac Surg 2015; 10:25. [PMID: 25880032 PMCID: PMC4345000 DOI: 10.1186/s13019-015-0225-x] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2014] [Accepted: 02/10/2015] [Indexed: 11/25/2022] Open
Abstract
Background All international guidelines recommend perioperative antibiotic prophylaxis (PAB) should be routinely administered to patients undergoing cardiac surgery. However, the duration of PAB is heterogeneous and controversial. Methods Between 01.01.2011 and 31.12.2011, 1096 consecutive cardiac surgery patients were assigned to one of two groups receiving PAB with a second-generation cephalosporin for either 56 h (group I) or 32 h (group II). Patients’ characteristics, intraoperative data, and the in-hospital follow-up were analysed. Primary endpoint was the incidence of surgical site infection (deep and superficial sternal wound-, and vein harvesting site infection; DSWI/SSWI/VHSI). Secondary endpoints were the incidence of respiratory-, and urinary tract infection, as well as the mortality rate. Results 615/1096 patients (56,1%) were enrolled (group I: n = 283 versus group II: n = 332). There were no significant differences with regard to patient characteristics, comorbidities, and procedure-related variables. No statistically significant differences were demonstrated concerning primary and secondary endpoints. The incidence of DSWI/SSWI/VHSI were 4/283 (1,4%), 5/283 (1,7%), and 1/283 (0,3%) in group I versus 6/332 (1,8%), 9/332 (2,7%), and 3/332 (0,9%) in group II (p = 0,76/0,59/0,63). In univariate analyses female gender, age, peripheral arterial obstructive disease, operating-time, ICU-duration, transfusion, and respiratory insufficiency were determinants for nosocomial infections (all ≤ 0,05). Subgroup analyses of these high-risk patients did not show any differences between the two regimes (all ≥ 0,05). Conclusions Reducing the duration of PAB from 56 h to 32 h in adult cardiac surgery patients was not associated with an increase of nosocomial infection rate, but contributes to reduce antibiotic resistance and health care costs.

Polymorphisms of Toll-like receptors (TLR2 and TLR4) are associated with the risk of infectious complications in acute myeloid leukemia. Genes Immun 2014; 16:83-8. [PMID: 25427560 DOI: 10.1038/gene.2014.67] [Citation(s) in RCA: 31] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2014] [Revised: 10/03/2014] [Accepted: 10/10/2014] [Indexed: 01/26/2023]
Abstract
Infectious complications continue to be one of the major causes of morbidity and mortality in patients with acute myeloid leukemia (AML). Several single-nucleotide polymorphisms (SNPs) of Toll-like receptors (TLRs) can affect the genetic susceptibility to infections or even sepsis. We sought to investigate the impact of different SNPs on the incidence of developing sepsis and pneumonia in patients with newly diagnosed AML following induction chemotherapy. We analyzed three SNPs in the TLR2 (Arg753Gln) and TLR4 (Asp299Gly and Thr399Ile) gene in a cohort of 155 patients with AML who received induction chemotherapy. The risk of developing sepsis and pneumonia was assessed by multiple logistic regression analyses. The presence of the TLR2 Arg753Gln polymorphism was significantly associated with pneumonia in AML patients (odds ratio (OR): 10.78; 95% confidence interval (CI): 2.0-58.23; P=0.006). Furthermore, the cosegregating TLR4 polymorphisms Asp299Gly and Thr399Ile were independent risk factors for the development of both sepsis and pneumonia (OR: 3.55; 95% CI: 1.21-10.4, P=0.021 and OR: 3.57, 95% CI: 1.3-9.86, P=0.014, respectively). To our best knowledge, this study represents the first analysis demonstrating that polymorphisms of TLR2 and TLR4 influence the risk of infectious complications in patients with AML undergoing induction chemotherapy.

Tidal volume and plateau pressure use for acute lung injury from 2000 to present: a systematic literature review. Crit Care Med 2014; 42:2278-89. [PMID: 25098333 DOI: 10.1097/ccm.0000000000000504] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 01/30/2023]
Abstract
OBJECTIVE Since publication of the Respiratory Management of Acute Lung Injury and Acute Respiratory Distress Syndrome (ARMA) trial in 2000, use of tidal volume (VT) less than or equal to 6 mL/kg predicted body weight with corresponding plateau airway pressures (PPlat) less than or equal to 30 cm H2O has been advocated for acute lung injury. However, compliance with these recommendations is unknown. We therefore investigated VT (mL/kg predicted body weight) and PPlat (cm H2O) practices reported in studies of acute lung injury since ARMA using a systematic literature review (i.e., not a meta-analysis). DATA SOURCES PubMed, Scopus, and EMBASE. STUDY SELECTION Randomized controlled trials and nonrandomized studies enrolling patients with acute lung injury from May 2000 to June 2013 and reporting VT. DATA EXTRACTION Whether the study was a randomized controlled trial or a nonrandomized study and performed or not at an Acute Respiratory Distress Syndrome Network center; in randomized controlled trials, the pre- and postrandomization VT (mL/kg predicted body weight) and PPlat (cm H2O) and whether a VT protocol was used postrandomization; in nonrandomized studies, baseline VT and PPlat. DATA SYNTHESIS Twenty-two randomized controlled trials and 71 nonrandomized studies were included. Since 2000 at acute respiratory distress syndrome Network centers, routine VT was similar comparing randomized controlled trials and nonrandomized studies (p = 0.25) and unchanged over time (p = 0.75) with a mean value of 6.81 (95% CI, 6.45, 7.18). At non-acute respiratory distress syndrome Network centers, routine VT was also similar when comparing randomized controlled trials and nonrandomized studies (p = 0.71), but decreased (p = 0.001); the most recent estimate for it was 6.77 (6.22, 7.32). All VT estimates were significantly greater than 6 (p ≤ 0.02). In randomized controlled trials employing VT protocols, routine VT was reduced in both acute respiratory distress syndrome Network (n = 4) and non-acute respiratory distress syndrome Network (n = 11) trials (p ≤ 0.01 for both), but even postrandomization was greater than 6 (6.47 [6.29, 6.65] and 6.80 [6.42, 7.17], respectively; p ≤ 0.0001 for both). In 59 studies providing data, routine PPlat, averaged across acute respiratory distress syndrome Network or non-acute respiratory distress syndrome Network centers, was significantly less than 30 (p ≤ 0.02). CONCLUSIONS For clinicians treating acute lung injury since 2000, achieving VT less than or equal to 6 mL/kg predicted body weight may not have been as attainable or important as PPlat less than or equal to 30 cm H2O. If so, there may be equipoise to test if VT less than or equal to 6 mL/kg predicted body weight are necessary to improve acute lung injury outcome.

Early therapy with IgM-enriched polyclonal immunoglobulin in patients with septic shock. Intensive Care Med 2014; 40:1888-96.

Abstract
PURPOSE To determine whether there was an association between adjunctive therapy with IgM-enriched immunoglobulin (IgM) and the 30-day mortality rate in patients with septic shock. METHODS In 2008 we introduced IgM as a possible adjunctive therapy to be provided within 24 h after shock onset in the management protocol for patients with septic shock. In this retrospective study we included the adult patients suitable for IgM therapy admitted to our ICU from January 2008 to December 2011. An unadjusted comparison between patients who did or did not receive IgM therapy, a multivariate logistic model adjusted for confounders and propensity score-based matching were used to evaluate the association between early IgM treatment and mortality. RESULTS One hundred and sixty-eight patients were included in the study. Of these, 92 (54.8%) received IgM therapy. Patients who did or did not receive IgM were similar with regards to infection characteristics, severity scores and sepsis treatment bundle compliance. Patients who received IgM were more likely to have blood cultures before antibiotics and to attain a plateau inspiratory pressure less than 30 cmH2O (p < 0.05). The 30-day mortality rate was reduced by 21.1% (p < 0.05) in the group that received IgM compared to the group that did not. The multivariate adjusted regression model (OR 0.17; CI 95% 0.06-0.49; p = 0.001) and the propensity score-based analysis (OR 0.35; CI 95% 0.14-0.85; p = 0.021) confirmed that IgM therapy was associated with reduced mortality at 30 days after the onset of septic shock. CONCLUSIONS Our experience indicates that early adjunctive treatment with IgM may be associated with a survival benefit in patients with septic shock. However, additional studies are needed to better evaluate the role of IgM therapy in the early phases of septic shock.

Abstract
Background Sepsis sequelae include critical illness polyneuropathy, myopathy, wasting, neurocognitive deficits, post-traumatic stress disorder, depression and chronic pain. Little is known howlong-term sequelae following hospital discharge are treated. The aim of our study is to determine the effect of a primary care-based, long-term program on health-related quality of life in sepsis survivors. Methods/Design In a two-armed randomized multicenter interventional study, patients after sepsis (n = 290) will be assessed at 6, 12 and 24 months. Patients are eligible if severe sepsis or septic shock (ICD-10), at least two criteria of systemic inflammatory response syndrome (SIRS), at least one organ dysfunction and sufficient cognitive capacity are present. The intervention comprises 1) discharge management, 2) training of general practitioners and patients in evidence-based care for sepsis sequelae and 3) telephone monitoring of patients. At six months, we expect an improved primary outcome (health-related quality of life/SF-36) and improved secondary outcomes such as costs, mortality, clinical-, psycho-social- and process-of-care measures in the intervention group compared to the control group. Discussion This study evaluates a primary care-based, long-term program for patients after severe sepsis. Study results may add evidence for improved sepsis care management. General practitioners may contribute efficiently to sepsis aftercare. Trial registration U1111-1119-6345. DRKS00000741, CCT-NAPN-20875 (25 February 2011).

Abstract
Introduction Severe infections in intensive care patients show high morbidity and mortality rates. Linezolid is an antimicrobial drug frequently used in critically ill patients. Recent data indicates that there might be high variability of linezolid serum concentrations in intensive care patients receiving standard doses. This study was aimed to evaluate whether standard dosing of linezolid leads to therapeutic serum concentrations in critically ill patients. Methods In this prospective observational study, 30 critically ill adult patients with suspected infections received standard dosing of 600 mg linezolid intravenously twice a day. Over 4 days, multiple serum samples were obtained from each patient, in order to determine the linezolid concentrations by liquid chromatography tandem mass spectrometry. Results A high variability of serum linezolid concentrations was observed (range of area under the linezolid concentration time curve over 24 hours (AUC24) 50.1 to 453.9 mg/L, median 143.3 mg*h/L; range of trough concentrations (Cmin) < 0.13 to 14.49 mg/L, median 2.06 mg/L). Furthermore, potentially subtherapeutic linezolid concentrations over 24 hours and at single time points (defined according to the literature as AUC24 < 200 mg*h/L and Cmin < 2 mg/L) were observed for 63% and 50% of the patients, respectively. Finally, potentially toxic levels (defined as AUC24 > 400 mg*h/L and Cmin > 10 mg/L) were observed for 7 of the patients. Conclusions A high variability of linezolid serum concentrations with a substantial percentage of potentially subtherapeutic levels was observed in intensive care patients. The findings suggest that therapeutic drug monitoring of linezolid might be helpful for adequate dosing of linezolid in critically ill patients. Trial registration Clinicaltrials.gov

Abstract
Dysphagia is a major risk factor for morbidity and mortality in critically ill patients treated in intensive care units (ICUs). Structured otorhinolaryngological data on dysphagia in ICU survivors with severe sepsis are missing. In a prospective study, 30 ICU patients with severe sepsis and thirty without sepsis as control group were examined using bedside fiberoptic endoscopic evaluation of swallowing after 14 days in the ICU (T1) and 4 months after onset of critical illness (T2). Swallowing dysfunction was assessed using the Penetration-Aspiration Scale (PAS). The Functional Oral Intake Scale was applied to evaluate the diet needed. Primary endpoint was the burden of dysphagia defined as PAS score >5. At T1, 19 of 30 severe sepsis patients showed aspiration with a PAS score >5, compared to 7 of 30 in critically ill patients without severe sepsis (p = 0.002). Severe sepsis and tracheostomy were independent risk factors for severe dysphagia with aspiration (PAS > 5) at T1 (p = 0.042 and 0.006, respectively). 4-month mortality (T2) was 57 % in severe sepsis patients compared to 20 % in patients without severe sepsis (p = 0.006). At T2, more severe sepsis survivors were tracheostomy-dependent and needed more often tube or parenteral feeding (p = 0.014 and p = 0.040, respectively). Multivariate analysis revealed tracheostomy at T1 as independent risk factor for severe dysphagia at T2 (p = 0.030). Severe sepsis appears to be a relevant risk factor for long-term dysphagia. An otorhinolaryngological evaluation of dysphagia at ICU discharge is mandatory for survivors of severe critical illness to plan specific swallowing rehabilitation programs.

Abstract
Procalcitonin (PCT) is used as a biomarker for the diagnosis of sepsis, severe sepsis and septic shock. At the same time, PCT has also been used to guide antibiotic therapy. This review outlines the main indications for PCT measurement and points out possible pitfalls. The classic indications for PCT measurement are: (i) confirmation or exclusion of diagnosis of sepsis, severe sepsis, or septic shock, (ii) severity assessment and follow up of systemic inflammation mainly induced by microbial infection, and (iii) individual, patient adapted guide of antibiotic therapy and focus treatment. Using serially monitored PCT levels, the duration and need of antibiotic therapy can be better adapted to the individual requirements of the patient. This individualized approach has been evaluated in various studies, and it is recommended to be a part of an antibiotic stewardship program.

Abstract
BACKGROUND Organ dysfunction consequent to infection ('severe sepsis') is the leading cause of admission to an intensive care unit (ICU). In both animal models and early clinical studies the calcium channel sensitizer levosimendan has been demonstrated to have potentially beneficial effects on organ function. The aims of the Levosimendan for the Prevention of Acute oRgan Dysfunction in Sepsis (LeoPARDS) trial are to identify whether a 24-hour infusion of levosimendan will improve organ dysfunction in adults who have septic shock and to establish the safety profile of levosimendan in this group of patients. METHODS/DESIGN This is a multicenter, randomized, double-blind, parallel group, placebo-controlled trial. Adults fulfilling the criteria for systemic inflammatory response syndrome due to infection, and requiring vasopressor therapy, will be eligible for inclusion in the trial. Within 24 hours of meeting these inclusion criteria, patients will be randomized in a 1:1 ratio stratified by the ICU to receive either levosimendan (0.05 to 0.2 μg.kg⁻¹.min⁻¹ or placebo for 24 hours in addition to standard care. The primary outcome measure is the mean Sequential Organ Failure Assessment (SOFA) score while in the ICU. Secondary outcomes include: central venous oxygen saturations and cardiac output; incidence and severity of renal failure using the Acute Kidney Injury Network criteria; duration of renal replacement therapy; serum bilirubin; time to liberation from mechanical ventilation; 28-day, hospital, 3 and 6 month survival; ICU and hospital length-of-stay; and days free from catecholamine therapy. Blood and urine samples will be collected on the day of inclusion, at 24 hours, and on days 4 and 6 post-inclusion for investigation of the mechanisms by which levosimendan might improve organ function. Eighty patients will have additional blood samples taken to measure levels of levosimendan and its active metabolites OR-1896 and OR-1855. A total of 516 patients will be recruited from approximately 25 ICUs in the United Kingdom. DISCUSSION This trial will test the efficacy of levosimendan to reduce acute organ dysfunction in adult patients who have septic shock and evaluate its biological mechanisms of action.

Improved management of sepsis during neutropenia may reduce the mortality of cancer therapies. Clinical guidelines on sepsis treatment have been published by others. However, optimal management may differ between neutropenic and non-neutropenic patients. Our aim is to give evidence-based recommendations for haematologist, oncologists and intensive care physicians on how to manage adult patients with neutropenia and sepsis.

Efficacy and feasibility of cyclophosphamide combined with intermediate- dose or high-dose cytarabine for relapsed and refractory acute myeloid leukemia (AML). J Cancer Res Clin Oncol 2014; 140:1391-7. [PMID: 24728467 DOI: 10.1007/s00432-014-1666-7] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2014] [Accepted: 03/28/2014] [Indexed: 11/26/2022]
Abstract
BACKGROUND Approximately, 70 % of adult patients with de novo acute myeloid leukemia (AML) achieve a complete remission (CR) while 10-20 % of AML are refractory to induction chemotherapy. Furthermore, a significant proportion of AML patients in CR will relapse during or after consolidation treatment. There is no evidence for a standard salvage regimen and most centers use a combination of an anthracycline and cytarabine (AraC). The aim of this study was to investigate the impact of two age-adjusted regimens containing AraC and cyclophosphamide applied for the treatment of relapsed or refractory AML. PATIENTS AND METHODS We retrospectively analyzed 60 patients (24 male, 36 female; median age 56 years) with relapsed or refractory AML who were treated with a combination of AraC and cyclophosphamide monocentrically between October 2000 and January 2013. Two different protocols containing either high-dose (hAC) or intermediate-dose cytarabin (iAC) have been applied dependent on age and performance status. RESULTS We demonstrate an overall response rate (CR + PR) induced by hAC and iAC of 56.7 %. Importantly, a complete remission rate (CR + CRp) of 52.2 % was found in patients who received the hAC regimen while only 8.8 % of patients achieved a CR following the iAC protocol (p < 0.001). The rate of refractory disease was 26.1 and 47.1 %, respectively. High-risk cytogenetics, i.e., a complex aberrant or monosomal karyotype had no effect on achievement of CR after hAC. In addition, there was no impact of activating FLT3 mutations on response to treatment according to the hAC regimen. In the cohort of patients treated with the iAC protocol, treatment-related mortality of 11.8 % within 60 days was observed but none of the patients who received the hAC regimen died within the first 2 months following chemotherapy. The toxicity profile was acceptable at both cytarabine dose levels. Importantly, 19 patients (82.6 %) of the hAC cohort underwent allogeneic hematopoietic stem cell transplantation (HSCT) as consecutive treatment. CONCLUSION The hAC regimen represents a promising therapeutic approach to induce a second CR in younger patients with relapsed or refractory AML prior to HSCT without using anthracyclines.

Therapeutic plasma exchange as rescue therapy in severe sepsis and septic shock: retrospective observational single-centre study of 23 patients. BMC Anesthesiol 2014; 14:24. [PMID: 24708653 PMCID: PMC3986467 DOI: 10.1186/1471-2253-14-24] [Citation(s) in RCA: 40] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2013] [Accepted: 03/31/2014] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND Several case series and small randomized controlled trials suggest that therapeutic plasma exchange (TPE) improves coagulation, hemodynamics and possibly survival in severe sepsis. However, the exact role of TPE in modern sepsis therapy remains unclear. METHODS We performed a retrospective observational single-centre study on the use of TPE as rescue therapy in 23 consecutive patients with severe sepsis or septic shock from 2005 to 2012. Main surrogate markers of multiple organ failure (MOF) before, during and after TPE as well as survival rates are reported. RESULTS At baseline, mean SOFA score was 13 (standard deviation [SD] 4) and median number of failed organ-systems was 5 (interquartile range [IQR] 4-5). TPEs were performed 3 days (IQR 2-10) after symptom onset and 1 day (IQR 0-8) after ICU admission. The median total exchange volume was 3750 ml (IQR 2500-6000), which corresponded to a mean of 1.5 times (SD 0.9) the individual plasma volume. Fresh frozen plasma was used in all but one treatments as replacement fluid. Net fluid balance decreased significantly within 12 hrs following the first TPE procedure by a median of 720 mL (p = 0.002), irrespective of outcome. Reductions of norepinephrine dose and improvement in cardiac index were observed in individual survivors, but this was not significant for the overall cohort (p = 0.574). Platelet counts decreased irrespective of outcome between days 0 and 2 (p < 0.003), and increased thereafter in many survivors. There was a non-significant trend towards younger age and higher procalcitonin levels among survivors. Nine out of 23 TPE treated patients (39%) survived until ICU discharge (among them 3 patients with baseline SOFA scores of 15, 17, and 20). CONCLUSIONS Our data suggest that some patients with severe sepsis and septic shock may experience hemodynamic stabilisation by early TPE therapy.
