Abstract
BACKGROUND Acute myeloid leukemia (AML) is a heterogenous and complex blood cancer requiring aggressive treatment. Early identification and prediction of the complications following treatment is vital for effective disease management. AIMS We explored associations between plasma protein levels and fever- and infection-related complications in 26 AML patients during chemotherapy-induced neutropenia. MATERIAL AND METHODS Longitudinal plasma profiling was conducted using data-dependent mass spectrometry analysis. RESULTS Mass spectrometry-based plasma profiling data correlated well with laboratory parameters, including C-reactive protein, and revealed a broader inflammation protein network associated with fever- and infection-related complications. DISCUSSION AND CONCLUSION These data indicate the potential of longitudinal plasma profiling in AML patients for identifying and predicting complications that may aid in improved disease monitoring and treatment.

Kim CJ. Current Status of Antibiotic Stewardship and the Role of Biomarkers in Antibiotic Stewardship Programs. Infect Chemother 2022; 54:674-698. [PMID: 36596680 PMCID: PMC9840952 DOI: 10.3947/ic.2022.0172] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2022] [Accepted: 12/19/2022] [Indexed: 12/27/2022] Open
Abstract
The importance of antibiotic stewardship is increasingly emphasized in accordance with the increasing incidences of multidrug-resistant organisms and accompanying increases in disease burden. This review describes the obstacles in operating an antibiotic stewardship program (ASP), and whether the use of biomarkers within currently available resources can help. Surveys conducted around the world have shown that major obstacles to ASPs are shortages of time and personnel, lack of appropriate compensation for ASP operation, and lack of guidelines or appropriate manuals. Sufficient investment, such as the provision of full-time equivalent ASP practitioners, and adoption of computerized clinical decision systems are useful measures to improve ASP within an institution. However, these methods are not easy in terms of both time commitments and cost. Some biomarkers, such as C-reactive protein, procalcitonin, and presepsin are promising tools in ASP due to their utility in diagnosis and forecasting the prognosis of sepsis. Recent studies have demonstrated the usefulness of algorithmic approaches based on procalcitonin level to determine the initiation or discontinuation of antibiotics, which would be helpful in decreasing antibiotics use, resulting in more appropriate antibiotics use.

Abstract
This study was designed to determine the utility of procalcitonin (PCT) and C-reactive protein (CRP) as predictors of Gram-negative bloodstream infection (GN-BSI) in hematological febrile outpatients at the time of the emergency unit admission. Overall, 286 febrile episodes, which included 42 GN-BSI (16%), were considered. PCT levels at patient admission were statistically higher in GNB-BSI when compared to Gram-positive bacteria BSI (median 4.06 ng/ml (range 1.10-25.04) vs 0.88 ng/ml (0.42-10), p<0.03) and to all other fever etiologies. For CRP, differences within fever etiologies were less profound but statistically significant, except for GN-BSIs vs GP BSIs (p=0.4). ROC analysis of PCT showed that an AUC of 0.85 (95%CI 0.79-0.95) discriminated GN-BSI from all other fever etiologies, with a best cut-off of 0.5 ng/ml, a negative predictive value (NPV) of 98%, and a negative likelihood ratio (negLR) of 0.1. ROC analysis of CRP showed an AUC of 0.67 (95%CI 0.53-0.81) with a best cut-off of 6.64 mg/dl, a NPV of 94%, and a negLR of 0.33. This study confirms that 0.5 ng/ml represents the PCT best cut-off to differentiate the cause of fever and rule out a GN-BSI in febrile hematologic outpatients at the time of the emergency unit admission. Therefore, introducing PCT testing could be a valid measure in order to tailor a more precise prompt antimicrobial therapy to the febrile outpatient while waiting for blood culture results.

Abstract
Background Fatal hemorrhagic pneumonia is one of the most severe manifestations of Stenotrophomonas maltophilia (SM) infections. Here, we aimed to investigate the clinical characteristics of SM bacteremia and to identify the risk factors of hemorrhagic pneumonia caused by SM in patients with hematologic diseases. Methods The clinical records of 55 patients diagnosed with hematologic diseases and SM bacteremia were retrospectively reviewed. We compared patients’ clinical characteristics and outcomes between the hemorrhagic pneumonia group and non-hemorrhagic pneumonia group. Results Twenty-seven (49.1%) patients developed hemorrhagic pneumonia. The overall mortality rate of SM bacteremia was 67.3%. Hemorrhagic pneumonia (adjusted HR 2.316, 95% CI 1.140–4.705; P = 0.020) was an independent risk factor of 30-day mortality in hematological patients with SM bacteremia. Compared with the non-hemorrhagic pneumonia group, patients in the hemorrhagic pneumonia group were older and showed clinical manifestations as higher proportions of isolated SM in sputum culture, neutropenia and elevated procalcitonin (PCT). Multivariate analysis showed that neutropenia, high levels of PCT, prior tigecycline therapy within 1 month were independent risk factors associated with hemorrhagic pneumonia. Conclusions Neutropenia, high level of PCT and prior tigecycline therapy within 1 month were significant independent predictors of hemorrhagic pneumonia in hematologic patients with SM bacteremia. Due to no effective antibiotics to prevent hemorrhagic pneumonia, prophylaxis of SM infection and its progression to hemorrhagic pneumonia is particularly important.

Abstract
INTRODUCTION Historically, the measurement of serum procalcitonin (PCT) levels in patients with leukopenia has been rejected without sufficient prospective evidence to justify this argument. On the other hand, the accumulated use of broad spectrum antibiotics in these patients and their consequences make the use of PCT attractive in an effort to reduce its use. PATIENTS AND METHODS We conducted a prospective study between 2016 and 2018, recruiting newly diagnosed FN patients, evaluating them with PCT levels during the first 24 h. After this we evaluate them with overall survival throughout the follow-up. RESULTS A total of 81 episodes of FN in 72 patients were included. We report a mortality of 27.2% in our cohort. The mean serum PCT in these patients was 4.01 ng/mL compared to 0.42 ng/mL in the survivors group (p < 0.01). Using ROC curves, we determined a cut-off point to predict septic shock/death at 0.46 ng/mL. Patients with a procalcitonin >0.46 ng/mL had an increased risk of death, with a HR of 4.43, (p = 0.048). CONCLUSION In conclusion, in our trial a single PCT on admission at a cut-off value of 0.46 ng/mL was able to predict the occurrence of septic shock and death in FN patients.

Abstract
BACKGROUND Endophthalmitis is a potentially blinding intraocular infection following intraocular surgery or trauma. Prompt diagnosis and treatment are important in preventing devastating visual complications. Procalcitonin (PCT) is a promising biomarker for diagnosing bacterial infections. The aim of the study was to measure vitreous PCT in infectious endophthalmitis and assess its utility as a biomarker. METHODS In this prospective study, vitreous was collected from patients with non-infectious retinal disorders and infectious endophthalmitis. PCT was measured using the Human Procalcitonin ELISA Kit. The diagnostic performance of PCT was calculated via receiver operating characteristic curves. RESULTS The study included three groups: patients with non-infectious retinal conditions, culture-positive endophthalmitis, and culture-negative endophthalmitis. The average PCT was 75.74 ± 26.8 pg mL-1, 100.24 ± 12.9 pg mL-1, and 126.41 ± 26.47 pg mL-1 in control, culture-negative, and culture-positive endophthalmitis, respectively. There was a significant difference in the vitreous PCT in the study and control groups (p = 0.04), but not between culture-positive and culture-negative endophthalmitis (p = 0.65). The sensitivity (66.7%) and specificity (65%) for PCT with a cut-off of ≤ 54.88 pg mL-1(p = 0.31) implied that its diagnostic accuracy was not significant. But there was a significant difference in gram-negative (68.2 ± 16.5 pg mL-1) and gram-positive (175.09 ± 45 pg mL-1) (p = 0.02) bacterial infections; the sensitivity and specificity were 70%, with a cut-off of ≤ 82.3 pg mL-1. CONCLUSIONS This study showed that vitreous procalcitonin concentration might not be a suitable biomarker for diagnosing culture-negative endophthalmitis though it could help distinguish between gram-positive and gram-negative infections.

Abstract
BACKGROUND We evaluated the diagnostic utility of procalcitonin (PCT) in predicting bacterial bloodstream infections (BSI) in critically ill cancer patients with and without neutropenia. We also investigated the role of PCT as a prognostic marker of supportive modalities (vasopressors, invasive mechanical ventilation, and renal replacement therapy (RRT)) in the intensive care unit (ICU). METHODS We retrospectively analyzed 2200 PCT and blood cultures from adult cancer patients with suspected sepsis. Primary outcome was BSI, defined by positive blood culture, collected within 72 h of PCT collection. RESULTS Median PCT values were higher in encounters with BSI (3.2 vs 0.5 ng/ml, p < 0.001). The area under the ROC curve (AUC) was 0.726 (95%CI 0.698, 0.754). PCT > 2.0 ng/ml was significantly associated with greater likelihood of BSI and this effect was significantly stronger for neutropenic (OR 9.09, 95%CI: 4.39, 18.79) compared with non-neutropenic patients (OR 4.00 (95% CI: 3.13, 5.10), interaction p = 0.036). PCT > 2.0 was associated with vasopressor requirement on ICU admission (OR 1.82 (95% CI 1.31, 2.53), p < 0.001) and RRT (OR 2.20 (95% CI 1.24, 3.91), p = 0.007). CONCLUSIONS Procalcitonin is a fair discriminator of BSI in critically ill cancer patients with and without neutropenia and a PCT > 2.0 ng/ml was significantly more likely to require vasopressors and RRT in the ICU.

Abstract
PURPOSE The purpose of this study was to evaluate the clinical significance of the biomarkers procalcitonin (PCT) and C-reactive protein (CRP) in patients with febrile neutropenia (FN) undergoing chemotherapy for acute leukemia. METHODS We conducted a prospective, observational study in patients who developed FN while undergoing chemotherapy for acute leukemia. PCT and CRP were obtained in patients who presented with FN. Blood cultures also were obtained. The primary goals were to evaluate the ability of PCT and CRP to predict bacteremia in patients with FN. The secondary goals were to assess the prognostic role of PCT and CRP and to assess the microbiologic profile and culture sensitivity patterns in the study population. RESULTS A total of 124 episodes of FN that involved 67 patients with acute leukemia occurred in the study. PCT was superior to CRP in the prediction of bacteremia. The median PCT level in the bacteremia group was 3.25 ng/mL compared with 0.51 ng/mL in the group without bacteremia (P < .01). The median values of CRP in the bacteremia and without-bacteremia groups were 119.3 mg/L and 94.5 mg/L, respectively (P = .07). There were no differences in median PCT and CRP in patients who died and those who improved. Of the 42 positive cultures, Gram-negative bacteremia was common (86%), and Escherichia coli was the most frequent organism isolated. Carbapenem resistance was seen in 39% of positive cultures. CONCLUSION PCT is an effective biomarker to predict bacteremia in patients with FN undergoing chemotherapy for acute leukemia.

[PMID: 32076461 PMCID: PMC7008263 DOI: 10.1155/2020/4873074] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/15/2019] [Accepted: 12/23/2019] [Indexed: 12/23/2022]
Abstract
Objective Gram-negative bloodstream infections (GNBSIs), especially those caused by antibiotic-resistant species, have become a public health challenge. Procalcitonin (PCT) showed promising potential in early diagnosis of GNBSI; however, little was known about its performance under different clinical settings. We here systematically assessed the diagnostic accuracy of PCT in recognizing GNBSI and made direct comparisons with C-reactive protein (CRP) and interleukin 6 (IL-6). Methods PubMed, Embase, ISI Web of Knowledge, and Scopus were searched from inception to March 15th, 2019. Area under the summary receiver operating characteristic curve (AUC), pooled sensitivity, specificity, and diagnostic odds ratio (DOR) were calculated. Hierarchical summary receiver operating characteristic (HSROC) model was used for the investigation of heterogeneity and for comparisons between markers. Results 25 studies incorporating 50933 suspected BSI episodes were included. Pooled sensitivity and specificity for PCT were 0.71 and 0.76, respectively. The overall AUC was 0.80. The lowest AUCs were found in patients with febrile neutropenia (0.69) and hematological malignancy (0.69). The highest AUC was found in groups using electrochemiluminescence immunoassay (0.87). In direct comparisons, PCT showed better overall performance than CRP with the AUC being 0.85 (95% CI 0.81–0.87) for PCT and 0.78 (95% CI 0.74–0.81) for CRP, but the relative DORs varied with thresholds between PCT and CRP (p < 0.001). No significant difference was found either in threshold (p < 0.001). No significant difference was found either in threshold (p < 0.001). No significant difference was found either in threshold ( Conclusions PCT was helpful in recognizing GNBSI, but the test results should be interpreted carefully with knowledge of patients' medical condition and should not serve as the only criterion for GNBSI. Further prospective studies are warranted for comparisons between different clinical settings.

Abstract
BACKGROUND Procalcitonin (PCT) is routinely used for an early recognition of severe infections and for promoting appropriate use of antibiotics. However, limited data correlating values of PCT with etiology of infection has been reported. METHODS During 2016, all positive blood cultures (BC) were retrospectively extracted in a 1100-beds Italian tertiary-care hospital. PCT and C-reactive protein (CRP) values were recorded within 24h from BC collection. Primary endpoint of the study was to investigate the correlation between PCT and CRP values and the occurrence of bloodstream infections (BSI) caused by bacteria or fungi. RESULTS During the study period, 1296 positive BC were included: 712 (54.9%) due to Gram-positive (GP), 525 (40.5%) due to Gram-negative (GN) strains, and 59 (4.6%) caused by fungi. Among GN isolates, enterobacteriaceae were reported in 453 (86.3%) cases. PCT values were higher in patients with GN etiology (26.1±14.2ng/mL) compared to GP (6.9±4.5) and fungi (3.3±2.4). Mean values for CRP in GN, GP, and fungi were not different. Receiver Operating Characteristic (ROC) curves showed an area under curve (AUC) of 0.71 for PCT and 0.51 for CRP among GN isolates; an AUC of 0.7 for PCT and 0.52 for CRP among enterobacteriaceae. Lower AUC for PCT were reported for GP and fungi. CONCLUSIONS PCT showed moderate performance in early detection (within 24h) of Gram-negative infections, especially those caused by enterobacteriaceae. Further prospective studies are mandatory to confirm these observations.

Abstract
OBJECTIVES Unnecessary use of antibiotics is an increasing problem. In this study, we sought to determine the diagnostic accuracy of procalcitonin in predicting bacteremia in children with a central line and fever, and we sought to determine optimal cutoff values to maximize sensitivity and specificity. This is the largest study to date in which procalcitonin is examined as a predictive marker of bacteremia in pediatric patients with a central line and fever. METHODS We conducted a retrospective cohort study of children aged 0 to 23 years with a central line and fever of 38°C who had procalcitonin and blood cultures drawn before initiation of antibiotics and had no other identified bacterial infection. Patients were also prospectively monitored via a custom-built electronic medical record dashboard for eligibility. RESULTS There were 523 patients and >2500 procalcitonin values reviewed for eligibility. Of these, 169 (47%) patients and 335 blood cultures with procalcitonin were included. There were 94 (28%) positive bacterial blood cultures and 241 (72%) negative bacterial blood cultures. In bacteremic cultures, the mean procalcitonin level was 9.96 ± 15.96 ng/mL, and the median procalcitonin level was 4.85 ng/mL (interquartile range 18.5). In nonbacteremic cultures, the mean procalcitonin level was 1.23 ± 10.37 ng/mL, and the median procalcitonin level was 0.3 ng/mL (interquartile range 0.7). A receiver operating characteristic analysis indicated a procalcitonin level of ≥0.6 ng/mL as the best cutoff point that produced a sensitivity of 85.6% and a specificity of 65.7% (area under the curve 0.85). CONCLUSIONS Procalcitonin is a sensitive biomarker in predicting bacteremia in children with a central line and fever.

Comparison of the Power of Procalcitonin and C-Reactive Protein to Discriminate between Different Aetiologies of Fever in Prolonged Profound Neutropenia: A Single-Centre Prospective Observational Study. Mediterr J Hematol Infect Dis 2019; 11:e2019023.

Abstract
Management of fever in prolonged, profound neutropenia remains challenging with many possible infectious and non-infectious causes. We investigated whether procalcitonin (PCT) is superior to C-reactive protein (CRP) in discriminating between different aetiologies of fever in this setting. CRP and PCT were tested daily during 93 neutropenic episodes in 66 patients. During this study period, 121 febrile episodes occurred and were classified into four categories based on clinical and microbiological findings: microbiologically documented infection (MDI); clinically documented infection (CDI); proven or probable invasive fungal disease (IFD); fever of unknown origin (FUO). Values of PCT and CRP at fever onset as well as two days later were considered for analysis of their performance in distinguishing aetiologies of fever. At fever onset, no significant difference in PCT values was observed between different aetiologies of fever, whereas median CRP values were significantly higher in case of IFD (median 98.8 mg/L vs 28.8 mg/L, p=0.027). Both PCT and CRP reached their peak at a median of 2 days after fever onset. Median PCT values on day 2 showed no significant difference between the aetiologies of fever. Median CRP values on day 2 were significantly higher in IFD (median 172 mg/L versus 78.4 mg/L, p=0.002). In MDI median CRP values rose > 100 mg/L, whereas they did not in CDI or FUO. PCT has no added value over CRP for clinical management of fever in prolonged, profound neutropenia. When performing reassessment 2 days after fever onset, CRP has better discriminatory power between aetiologies of fever.

Abstract
The aim of this study was to explore the predictive value of procalcitonin (PCT) in Gram-negative bloodstream infections (BSIs) in hematological patients with febrile neutropenia. A total of 1466 samples (396 blood culture (BC)-positive, 1052 BC-negative, and 18 contaminated specimens) were included, comprising 268 Gram-negative, 88 Gram-positive, 19 fungal, and 21 polymicrobial BSIs. Median PCT value (0.72 ng/mL; IQR: 0.23-3.87) was significantly higher in Gram-negative than Gram-positive (0.34 ng/mL; IQR: 0.14-2.23; p < .01), or fungal (0.27 ng/mL; IQR: 0.13-0.40; p < .01) BSIs. In mono-microbial BSIs, the best PCT cutoff distinguishing Gram-negative BSIs from all other fever causes was 0.56 ng/ml, with a specificity of 76.8%. PCT levels were significantly higher in BSIs from multidrug-resistant (MDR) Gram-negative strains than from non-MDR (p < .01). This study confirms that elevated PCT may predict Gram-negative BSIs in hematological patients with febrile neutropenia, and demonstrates higher PCT levels in MDR Gram-negative BSIs in these patients.

Abstract
Background This study aimed to evaluate the accuracy of procalcitonin (PCT) serum concentrations to diagnose Gram-negative bacteremia and the association of PCT serum concentrations with more specific pathogens and the focus of infection. Methods Secondary analysis of the prospectively collected patient-level dataset from a cluster randomized quality improvement trial was performed. The trial included sepsis patients with organ dysfunction treated in the participating intensive care units from 2011 to 2015. Test performance for the prediction of Gram-negative bacteremia was assessed by receiver operating curve analysis. Independent effects of specific pathogen groups and foci of infection on PCT concentrations were assessed by linear logistic regression models. Results Blood cultures (BC) and PCT concentrations had been taken in 4858 of 6561 documented patients. PCT was significantly higher in Gram-negative bacteremia compared to Gram-positive bacteremia or candidemia (p < 0.001). The area under the curve was 0.72 (95% confidence interval 0.71–0.74) for the prediction of Gram-negative bacteremia compared to all other blood culture results including negative blood cultures. The optimized cutoff value was 10 ng/ml (sensitivity 69%, specificity 35%). PCT differed significantly between specific groups of pathogens (p < 0.001) with highest concentrations in Escherichia coli, Streptococcus species and other Enterobacteriaceae. PCT was highest in urogenital followed by abdominal infection and lowest in respiratory infection (p < 0.001). In a linear regression model, Streptococci, E. coli and other Enterobacteriaceae detected from BC were associated with three times higher PCT values. Urogenital or abdominal foci of infection were associated with twofold increased PCT values independent of the pathogen. Conclusions Serum PCT concentrations are higher in patients with Gram-negative bacteremia than in patients with Gram-positive bacteremia or candidemia. However, the discriminatory power of this difference is too low to guide therapeutic decisions. Variations in PCT serum concentrations are not determined solely by Gram-negative or Gram-positive bacteria but are also affected by distinct groups of pathogens and different foci of infection.

Abstract
Background Novel potential small molecular biomarkers for sepsis were analyzed with nontargeted metabolite profiling to find biomarkers for febrile neutropenia after intensive chemotherapy for hematological malignancies. Methods Altogether, 85 patients were included into this prospective study at the start of febrile neutropenia after intensive chemotherapy for acute myeloid leukemia or after autologous stem cell transplantation. The plasma samples for the nontargeted metabolite profiling analysis by liquid chromatography-mass spectrometry were taken when fever rose over 38° and on the next morning. Results Altogether, 90 differential molecular features were shown to explain the differences between patients with complicated (bacteremia, severe sepsis, or fatal outcome) and noncomplicated courses of febrile neutropenia. The most differential compounds were an androgen hormone, citrulline, and phosphatidylethanolamine PE(18:0/20:4). The clinical relevance of the findings was evaluated by comparing them with conventional biomarkers like C-reactive protein and procalcitonin. Conclusion These results hold promise to find out novel biomarkers for febrile neutropenia, including citrulline. Furthermore, androgen metabolism merits further studies.

Abstract
BACKGROUND Children undergoing treatment for acute lymphoblastic leukemia (ALL) often present to the emergency department (ED) with a fever. They are at high risk of bacteremia secondary to being immunocompromised. Recent reports indicate that procalcitonin (PCT) is a useful marker of bacteremia in children. OBJECTIVE Our objective was to evaluate the clinical utility of PCT as a rapid marker of bacteremia in children with ALL presenting to the ED with a fever. In addition, we compared the results of PCT with white blood cell (WBC) count, erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP). METHODS Retrospective chart reviews were conducted of 492 patients with a total of 735 visits presenting to the ED from January 2009 to June 2012 with fever and a history of ALL where a PCT and a blood culture (BC) were obtained,. Positive BCs determined to be contaminants were excluded. The predictive powers of PCT, WBC, ESR, and CRP for bacteremia were evaluated using the area under the receiver operating characteristic curve with 95% confidence intervals (CI). In addition, each of the 4 markers were also examined in a logistic regression model as a potential predictor of the BC result. RESULTS A total of 735 PCT values were correlated with BC results. There were 76 (10.3%) true-positive BCs. The area under the receiver operating characteristic curve was 0.729 (95% CI, 0.661-0.792) for PCT, 0.685 (95% CI, 0.531-0.823) for ESR, 0.622 (95% CI, 0.460-0.796) for CRP, and 0.567 (95% CI, 0.483-0.649) for WBC. When logistic regression was used, the transformation log PCT was significantly associated with BC result whereas each of the other 3 markers, after appropriate transformation to remove heavy skewness, was not significant (all P > 0.1). A doubling of PCT was associated with an odds ratio of 1.32 for positive BCs (95% CI, 1.15-1.53). CONCLUSIONS Procalcitonin value was significantly associated with positive BC (P < 0.0001). The diagnostic performance of PCT was better than the other markers of inflammation. Its use in the ED in a select population of patients may be of significant value in identifying bacteremia. This has the potential to lead to a decrease in unwarranted use of antibiotics, hospital length of stay, and health care expenditures.

Abstract
Danger-associated molecular patterns (DAMPs) are activated by endogenous signals that originate from stressed, injured, or necrotic cells, signifying "danger" to the host. In this study, we evaluated the expression of the DAMP heat shock protein 70 (HSP70) in trauma patients with and without secondary infections. Levels of glucose (GLU), procalcitonin (PCT), total cholesterol (T-Chol), and white blood cell (WBC) counts were also evaluated at three time stages after trauma. Our analysis showed that the levels of serum HSP70 in patients with minor, moderate, and severe injuries were significantly higher than in healthy patients at each time point post-injury (P < 0.01), and levels of serum HSP70 in the severe injury group were significantly higher than in the minor injury group at 1-6 h after trauma (P = 0.047). HSP70 was correlated with GLU and was negatively correlated with T-Chol in the period 1-6 h after injury (P = 0.008/0.032). WBC and GLU were elevated after trauma, with mutual positive correlation (P < 0.001). PCT levels increased later than WBC counts and GLU levels; these levels were correlated at the two later time periods, 24-48 h and 60-90 h (P = 0.008/0.041). PCT continued to rise in patients with secondary infection, but PCT dropped at the third time period in patients without secondary infection. In summary, our results suggest that danger and stress theory can be used to predict severity of trauma.

Abstract
Early diagnosis and prompt targeted therapy are essential for septic patients' outcome. Procalcitonin (PCT) has been shown to predict bacteraemia and bacterial DNAaemia. Presepsin, the circulating soluble form of CD14 subtype, increases in response to bacterial infections, and is considered a new, emerging, early marker for sepsis. We evaluated the diagnostic accuracy of presepsin in predicting bacteraemia and bacterial DNAaemia in 92 patients with suspected sepsis, and we compared it with that of PCT and C-reactive protein (CRP). Presepsin median values were significantly higher in bacteraemic vs non-bacteraemic patients [1290 pg ml-1, interquartile range (IQR) 1005-2041 vs 659 pg ml-1, IQR 381-979; P<0.001] and in patients with vs patients without bacterial DNAaemia (1297 pg ml-1, IQR 1001-2046 vs 665 pg ml-1, IQR 381-940; P<0.001). Receiver operating characteristics analysis showed an area under the curve (AUC) for presepsin of 0.788 [95 % confidence interval (CI): 0.687-0.889; P<0.001] in predicting bacteraemia and of 0.777 (95 % CI: 0.676-0.878; P<0.001) in predicting bacterial DNAaemia, lower, but not significantly different, than those of PCT (0.876, P=0.12 and 0.880, P=0.07, respectively). Both biomarkers performed significantly better than CRP, which had an AUC for bacteraemia of 0.602 and for DNAaemia of 0.632 (all P values <0.05). In conclusion, in patients with suspected sepsis, presepsin and PCT showed a good diagnostic accuracy in predicting both bacteraemia and bacterial DNAaemia, superior to CRP.

Abstract
BACKGROUND Neutropaenic patients are at a high risk of contracting severe infections. In particular, in these patients, parameters with a high negative predictive value are desirable for excluding infection or bacteraemia. This study evaluated sepsis biomarkers in neutropaenic patients suffering from systemic inflammatory response syndrome (SIRS). Further, the predictive capacities of evaluated biomarkers in neutropaenic SIRS patients were compared to non-neutropaenic SIRS patients. MATERIAL AND METHODS In this prospective observational cohort study, patients with clinically suspected sepsis were screened. The predictive capacities of procalcitonin (PCT), C-reactive protein and lipopolysaccharide-binding protein (LBP) in neutropaenic SIRS patients were evaluated in terms of their potential to identify infection or bacteraemia and were compared to results for non-neutropaenic SIRS patients. To select an appropriate control cohort, propensity score matching was applied, balancing confounding factors between neutropaenic and non-neutropaenic SIRS patients. RESULTS Of 3370 prospectively screened patients with suspected infection, 51 patients suffered from neutropaenic SIRS. For the identification of infection, none of the assessed biomarkers presented a clinically relevant discriminatory potency. Lipopolysaccharide-binding protein and PCT demonstrated discriminatory capacity to discriminate between nonbacteraemic and bacteraemic SIRS in patients with neutropaenia [receiver-operating characteristics-area under the curves (ROC-AUCs): 0.860, 0.818]. In neutropaenic SIRS patients, LBP had a significantly better ROC-AUC than in a comparable non-neutropaenic patient cohort for identifying bacteraemia (P = 0.01). CONCLUSION In neutropaenic SIRS patients, none of the evaluated biomarkers was able to adequately identify infection. LBP and PCT presented a good performance in identifying bacteraemia. Therefore, these markers could be used for screening purposes to increase the pretest probability of blood culture analysis.

Pros and cons of using biomarkers versus clinical decisions in start and stop decisions for antibiotics in the critical care setting. Intensive Care Med 2015; 41:1739-51.

Abstract
INTRODUCTION Patients in the intensive care unit (ICU) frequently receive prolonged or even unnecessary antibiotic therapy, which selects for antibiotic-resistant bacteria. Over the last decade there has been great interest in biomarkers, particularly procalcitonin, to reduce antibiotic exposure. METHODS In this narrative review, we discuss the value of biomarkers and provide additional information beyond clinical evaluation in order to be clinically useful and review the literature on sepsis biomarkers outside the neonatal period. Both benefits and limitations of biomarkers for clinical decision-making are reviewed. RESULTS Several randomized controlled trials (RCTs) have shown the safety and efficacy of procalcitonin to discontinue antibiotic therapy in patients with severe sepsis or septic shock. In contrast, there is limited utility of procalcitonin for treatment initiation or withholding therapy initially. In addition, an algorithm using procalcitonin for treatment escalation has been ineffective and is probably associated with poorer outcomes. Little data from interventional studies are available for other biomarkers for antibiotic stewardship, except for C-reactive protein (CRP), which was recently found to be similarly effective and safe as procalcitonin in a randomized controlled trial. We finally briefly discuss biomarker-unrelated approaches to reduce antibiotic duration in the ICU, which have shown that even without biomarker guidance, most patients with sepsis can be treated with relatively short antibiotic courses of approximately 7 days. CONCLUSIONS In summary, there is an ongoing unmet need for biomarkers which can reliably and early on identify patients who require antibiotic therapy, distinguish between responders and non-responders and help to optimize antibiotic treatment decisions among critically ill patients. Available evidence needs to be better incorporated in clinical decision-making.

Abstract
Procalcitonin (PCT) can discriminate bacterial from viral systemic infections and true bacteremia from contaminated blood cultures. The aim of this study was to evaluate PCT diagnostic accuracy in discriminating Gram-positive, Gram-negative, and fungal bloodstream infections. A total of 1,949 samples from patients with suspected bloodstream infections were included in the study. Median PCT value in Gram-negative (13.8 ng/mL, interquartile range (IQR) 3.4–44.1) bacteremias was significantly higher than in Gram-positive (2.1 ng/mL, IQR 0.6–7.6) or fungal (0.5 ng/mL, IQR 0.4–1) infections (P < 0.0001). Receiver operating characteristic analysis showed an area under the curve (AUC) for PCT of 0.765 (95% CI 0.725–0.805, P < 0.0001) in discriminating Gram-negatives from Gram-positives at the best cut-off value of 10.8 ng/mL and an AUC of 0.944 (95% CI 0.919–0.969, P < 0.0001) in discriminating Gram-negatives from fungi at the best cut-off of 1.6 ng/mL. Additional results showed a significant difference in median PCT values between Enterobacteriaceae and nonfermentative Gram-negative bacteria (17.1 ng/mL, IQR 5.9–48.5 versus 3.5 ng/mL, IQR 0.8–21.5; P < 0.0001). This study suggests that PCT may be of value to distinguish Gram-negative from Gram-positive and fungal bloodstream infections. Nevertheless, its utility to predict different microorganisms needs to be assessed in further studies.

Abstract
Procalcitonin (PCT) has emerged as the most promising marker of infectious inflammation. This development is critical to the practicing doctor dealing with febrile patients with suspected sepsis. An ideal biomarker would provide data for early diagnosis, differentiation of bacterial from non-bacterial causes of inflammation and information about the clinical course and prognosis of the disease. PCT is an early biomarker that is present within 3 to 4 hours of the triggering infection. An undetectable PCT level would efficiently rule out systemic infection. PCT may also be viewed as a marker of resolving infection as it has a half-life of about 22 hours, and its blood level correlates with bacterial load. Thus, PCT may be used as a clinical tool for early diagnosis, prognosis and therapeutic guide. Automated platforms with short assay times and service that is available 24 hours a day have enabled clinicians to obtain rapid reliable results for the early diagnosis and timely monitoring of appropriate pharmacotherapy. Clinicians should use PCT as an adjunct to clinical and other diagnostic criteria.

Abstract
There is growing interest in the use of procalcitonin as a biomarker of bacterial infection. In particular, focus has been on the use of procalcitonin to facilitate a more timely diagnosis of sepsis and to guide the appropriate duration of antibiotic therapy. However, there is a lack of consensus in the literature concerning the role of measuring procalcitonin levels in clinical practice. This article reviews the evidence surrounding the utility of this biomarker for patients with sepsis in the intensive care environment. It is concluded that raised procalcitonin levels add little as a diagnostic criterion, however evidence supports the incorporation of procalcitonin-based algorithms relating to antibiotic stewardship in this patient population.

Abstract
BACKGROUND The aim of this study was to assess the diagnostic value of procalcitonin (PCT) in emergency department (ED) patients with suspected appendicitis. METHODS A prospective observational study was carried out in the emergency department of a university hospital between July 2007 and June 2008. Adult patients who presented to the ED with clinically suspected appendicitis were enrolled. Each patient underwent serum PCT, C-reactive protein (CRP), and Alvarado score evaluation on admission. The results of these three measurements were analyzed in relation to the final diagnosis determined by histopathological findings or compatible computed tomography findings. RESULTS Of the 214 study patients, 113 (52.8 %) had a confirmed diagnosis of appendicitis and 58 had complicated appendicitis (phlegmon, perforation, or gangrene). For the diagnosis of appendicitis, the area under the receiving operating characteristic (ROC) curve is 0.74 for Alvarado score, 0.69 for PCT, and 0.61 for CRP. Overall, the Alvarado score has the best discriminative capability among the three tested markers. We adopted two cutoff point approaches to harness both ends of the diagnostic value of a biomarker. PCT levels were significantly higher in patients with complicated appendicitis. For diagnosis of complicated appendicitis, a cutoff value of 0.5 ng/mL had a sensitivity of 29 % and a specificity of 95 %, while a cutoff value of 0.05 ng/ml had a sensitivity of 85 % and a specificity of 30 % in diagnosing complicated appendicitis. For those with a PCT value in the gray zone, clinical findings may play a more important role. CONCLUSION The study does not support the hypothesis that the PCT test may be useful for screening ED patients for appendicitis. However, determination of the PCT level may be useful for risk assessment of ED patients with suspected complicated appendicitis.

Abstract
OBJECTIVE To evaluate the clinical use of procalcitonin (PCT) as a rapid marker for the identification of bacteremia in the emergency department (ED) population of children with fever and a central venous catheter (CVC). METHODS Children were identified on presentation to the ED with a chief complaint of fever and who had a CVC. Fever was defined as 38°C or higher orally. Patients were excluded from the study if they had received antibiotics within the previous 24 hours of presenting to the ED, if they had a peripherally inserted central catheter line or by parental refusal. On presentation to the ED, all patients had a complete blood cell count with differential, blood culture from the central line, and PCT levels drawn. All had empiric antibiotics initiated. Blood culture results were recorded, and in the case of positive cultures, time to positive culture was noted. RESULTS Sixty-two patients (aged 5 months-18 y) were enrolled, and 14 (23%) had a positive culture. Mean PCT value in bacteremic patients was 18.47 ± 31.6 ng/mL and 0.65 ± 1.2 ng/mL in nonbacteremic patients (P < 0.001). Median PCT for negative blood culture was 0.23 ng/mL (interquartile range, 0.11-0.61) and 1.15 ng/mL for a positive blood culture (interquartile range, 0.45-29.16). The receiver operating characteristic analysis identified a level of PCT of 0.3 ng/mL as the best cutoff point that produced a sensitivity of 93% and a specificity of 63% (area under the curve, 0.82). CONCLUSIONS The PCT levels are useful in identifying children with fever and a CVC who are bacteremic in the ED.

Abstract
Early diagnosis of complicated course in febrile neutropenia is cumbersome due to the non-specificity of clinical and laboratory signs of severe infection. This prospective study included 100 adult hematological patients with febrile neutropenia after intensive chemotherapy at the onset of fever (d0) and for 3 days (d1-d3) thereafter. The study aim was to find early predictors for complicated course of febrile neutropenia, defined as bacteremia or septic shock. Interleukin 6 (IL-6), interleukin 10 (IL-10), procalcitonin (PCT) and C-reactive protein (CRP) all predicted complicated course of febrile neutropenia on d0, but only PCT was predictive throughout the study period. For IL-10 on d0-1 with cut-off 37 ng/L, sensitivity was 0.71, specificity 0.82, positive predictive value 0.52 and negative predictive value 0.92. For PCT on d0-1 with cut-off 0.13 μg/L, the respective measures were 0.95, 0.53, 0.36, and 0.98. For the combination of IL-10 and PCT on d0-1 with the same cut-offs, specificity improved to 0.85 and positive predictive value to 0.56. In conclusion, the present study confirms the high negative predictive value of PCT and provides new evidence for IL-10 as an early predictor for complicated course of febrile neutropenia in hematological patients. Combining IL-10 with PCT improves the early prediction for complicated course of febrile neutropenia.

Abstract
PURPOSE OF REVIEW Most patients with chemotherapy-induced febrile neutropenia recover rapidly without serious complications. However, it still remains a life-threatening treatment-related toxicity, and is associated with dose reductions and delays of chemotherapeutic agents that may compromise treatment outcomes. Recent developments of risk stratification enabled early discharge with oral antibiotics for low-risk patients. However, even in low-risk patients, medical complications including bacteremia could happen. The authors reviewed recent literature to provide an update on research regarding predictive factors for poor prognosis in patients with febrile neutropenia. RECENT FINDINGS Various prognostic factors have been suggested with controversies. Hematological parameters, prophylactic measurements and patient-specific risk factors showed inconsistent results. MASCC risk-index score, which was originally developed to identify low-risk patients, in turn showed that the lower the MASCC score, the poorer the prognosis of febrile neutropenia, with very low levels (<15), the rate of complications was high. Patients with severe sepsis and septic shock commonly had procalcitonin concentration above 2.0 ng/ml, and this level should be considered at high risk of poor prognosis. SUMMARY Lower MASCC score and higher procalcitonin concentration can predict poor outcomes in febrile neutropenia. More research is required with regard to the other factors showing controversies.

Abstract
Aim To identify predictors of bacteremia in critically ill patients, to evaluate the impact of blood cultures on the outcome, and to define conditions for breakthrough bacteremia despite concurrent antibiotic treatment. Methods A descriptive retrospective study was performed over a two-year period (2007-2008) in the medico-surgical Intensive Care Unit (ICU) of the San Giovanni Hospital in Bellinzona, Switzerland. Results Forty-five out of 231 patients (19.5%) had positive blood cultures. Predictors of positive blood cultures were elevated procalcitonin levels (>2 µg/L, P < 0.001), higher severity scores (Simplified Acute Physiology Score II>43, P = 0.014; Sequential Organ Failure Assessment >4.0, P < 0.001), and liver failure (P = 0.028). Patients with bacteremia had longer hospital stays (31 vs 21 days, P = 0.058), but their mortality was not different from patients without bacteremia. Fever (t > 38.5°C) only showed a trend toward a higher rate of blood culture positivity (P = 0.053). The rate of positive blood cultures was not affected by concurrent antibiotic therapy. Conclusions The prediction of positive blood culture results still remains a very difficult task. In our analysis, blood cultures were positive in 20% of ICU patients whose blood was cultured, and positive findings increased with elevated procalcitonin levels, liver failure, and higher severity scores. Blood cultures drawn >4 days after the start of antibiotic therapy and >5 days after surgery could detect pathogens responsible for a new infection complication.

Abstract
Procalcitonin (PCT) has recently emerged as a powerful biomarker for an early and accurate diagnosis of bacterial infection. Here we summarize our current understanding of the expression pathways of PCT, its potential cellular sources including immune cells, and factors inducing its secretion. Also addressed is the significance of increased blood PCT concentration, which may allow this molecule not only to act as a clinical biomarker but also as an active participant in the development and progression of infectious processes. Experimental approaches to delineate a better understanding of PCT functions, molecular pathways that modulate its expression and therapeutic opportunities to curtail its biological actions are discussed, as well.

Abstract
BACKGROUND Despite advances in therapy, sepsis still has a high mortality rate. To improve the treatment outcome, early diagnosis and treatment is essential, as reflected in many publications about biomarkers for sepsis. Recent models of automatic cell analyzers provide the delta neutrophil index (DN), which corresponds to the fraction of immature granulocytes in circulating blood. This study investigated DN as a prognostic marker in patients with bacteraemia. METHODS We retrospectively collected data on adult patients with bacteraemia admitted to an urban hospital between November 2009 and April 2010. The DN was measured at the onset of bacteraemia and at 24 and 72 h later. Factors associated with 28-day mortality were assessed using logistic regression. RESULTS A total of 102 patients were included in the analysis, and 24 patients died within 28 days. In the univariate analysis, appropriate antibiotic treatment, multidrug-resistant bacterial infection, history of intensive care unit (ICU) stay before the onset of bacteraemia, healthcare-associated infection, DN at 72 h after the onset of bacteraemia (DN-72 h), and platelet count at the onset of bacteraemia were significantly associated with survival. In multivariate analysis, DN-72 h (odds ratio (OR) 1.246, 95% confidence interval (CI) 1.030-1.508; p = 0.023), platelet count at the onset of bacteraemia (OR 0.986, 95% CI 0.977-0.995; p = 0.003), and history of ICU stay before the onset of bacteraemia (OR 4.907, 95% CI 1.045-23.051; p = 0.044) were the independent factors associated with survival. CONCLUSION DN at 72 h after bacteraemia may be valuable to assess the prognosis of patients with bacteraemia.

Abstract
BACKGROUND Increasing numbers of studies identify new prognostic factors for categorising chemotherapy-induced febrile neutropenia adult cancer patients into high- or low-risk groups for adverse outcomes. These groupings are used to tailor therapy according to level of risk. However many emerging factors with prognostic significance remain controversial, being based on single studies only. OBJECTIVES A systematic review was conducted to determine the strength of association of all identified factors associated with the outcomes of chemotherapy-induced febrile neutropenia patients. INCLUSION CRITERIA The participants included were adults of 15 years old and above, with a cancer diagnosis and who underwent cancer treatment.The review focused on clinical factors and their association with the outcomes of cancer patients with chemotherapy-induced febrile neutropenia at presentation of fever.All quantitative studies published in English which investigated clinical factors for risk stratification of adult cancer patients with chemotherapy-induced febrile neutropenia were considered.The primary outcome of interest was to identify the clinical factors for risk stratification of adult cancer patients with chemotherapy-induced febrile neutropenia. SEARCH STRATEGY Electronic databases searched from their respective inception date up to December 2011 include MEDLINE, EMBASE, CINAHL, Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science, Science-Direct, Scopus and Mednar. METHODOLOGICAL QUALITY The quality of the included studies was subjected to assessment by two independent reviewers. The standardised critical appraisal tool from the Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument (JBI-MAStARI) was used to assess the following criteria: representativeness of study population; clearly defined prognostic factors and outcomes; whether potential confounders were addressed and appropriate statistical analysis was undertaken for the study design. DATA COLLECTION Data extraction was performed using a modified version of the standardised extraction tool from the JBI-MAStARI. Prognostic factors and the accompanying odds ratio reported for the significance of these factors that were identified by multivariate regression, were extracted from each included study. DATA SYNTHESIS Studies results were pooled in statistical meta-analysis using Review Manager 5.1. Where statistical pooling was not possible, the findings were presented in narrative form. RESULTS Seven studies (four prospective cohort and three retrospective cohort) investigating 22 factors in total were included. Fixed effects meta-analysis showed: hypotension [OR=1.66, 95%CI, 1.14-2.41, p=0.008] and thrombocytopenia [OR=3.92, 95%CI, 2.19-7.01, p<0.00001)] were associated with high-risk of adverse outcomes for febrile neutropenia. Other factors that were statistically significant from single studies included: age of patients, clinical presentation at fever onset, presence or absence of co-morbidities, infections, duration and severity of neutropenia state. Five prognostic factors failed to demonstrate an association between the variables and the outcomes measured and they include: presence of pneumonia, total febrile days, median days to fever, recovery from neutropenia and presence of moderate clinical symptoms in association with Gram-negative bacteraemia. CONCLUSIONS Despite the overall limitations identified in the included studies, this review has provided a synthesis of the best available evidence for the prognostic factors used in risk stratification of febrile neutropenia patients. However, the dynamic aspects of prognostic model development, validation and utilisation have not been addressed adequately thus far. Given the findings of this review, it is timely to address these issues and improve the utilisation of prognostic models in the management of febrile neutropenia patients. IMPLICATIONS FOR PRACTICE The identified factors are similar to the factors in current prognostic models. However, additional factors that were reported to be statistically significant in this review (thrombocytopenia, presence of central venous catheter, and duration and severity of neutropenia) have not previously been included in prognostic models. This review has found these factors may improve the performance of current models by adding or replacing some of the factors. IMPLICATIONS FOR RESEARCH The role of risk stratification of chemotherapy-induced febrile neutropenia patients continues to evolve as the practice of risk-based therapy has been demonstrated to be beneficial to patients, clinicians and health care organisations. Further research to identify new factors /markers is needed to develop a new model which is reliable and accurate for these patients, regardless of cancer types. A robust and well-validated prognostic model is the key to enhance patient safety in the risk-based management of cancer patients with chemotherapy-induced febrile neutropenia.

Abstract
There are a number of limitations to using conventional diagnostic markers for patients with clinical suspicion of infection. As a consequence, unnecessary and prolonged exposure to antimicrobial agents adversely affect patient outcomes, while inappropriate antibiotic therapy increases antibiotic resistance. A growing body of evidence supports the use of procalcitonin (PCT) to improve diagnosis of bacterial infections and to guide antibiotic therapy. For patients with upper and lower respiratory tract infection, post-operative infections and for severe sepsis patients in the intensive care unit, randomized-controlled trials have shown a benefit of using PCT algorithms to guide decisions about initiation and/or discontinuation of antibiotic therapy. For some other types of infections, observational studies have shown promising first results, but further intervention studies are needed before use of PCT in clinical routine can be recommended. The aim of this review is to summarize the current evidence for PCT in different infections and clinical settings, and discuss the reliability of this marker when used with validated diagnostic algorithms.

Abstract
We compared biomarkers and their changes as predictors for bacteremia and severe sepsis during neutropenic fever after intensive chemotherapy in hematological patients. Serum C-reactive protein (CRP), semi-quantative procalcitonin, aminoterminal pro-brain natriuretic peptide (NT-proBNP), cortisol, lactate, plasma antithrombin and fibrinogen were measured daily from day 0 to day 3/day 4 in 89 neutropenic fever episodes of 65 hematological patients. The best predictors for bacteremia and gram-negative bacteremia were procalcitonin and its change, with odds ratios (ORs) and 95% confidence intervals of 2.63 (1.56-4.44) and 3.20 (1.77-5.80) for bacteremia and 4.14 (2.00-8.58) and 5.04 (2.18-11.63) for gram-negative bacteremia, respectively. For severe sepsis, the best predictors were CRP and fibrinogen, with ORs of 1.94 (1.07-3.52) and 1.92 (1.05-3.54). Factor analysis provided two predictive factors: procalcitonin-NT-proBNP-antithrombin factor predicted gram-negative bacteremia and CRP-fibrinogen predicted severe sepsis. Applying a combination of markers reflecting different aspects of infection might improve the recognition of risk for complications in patients with neutropenic fever.
