Abstract
Introduction Urosepsis is a systemic, dysregulated, inflammatory reaction to a urinary tract infection and can have severe effects on all systems, which can often lead to multi-organ failure and death. Sepsis-associated delirium is a common complication in critically ill patients, contributing to adverse outcomes and prolonged hospital stays. The neutrophil-to-lymphocyte ratio (NLR) has emerged as a potential biomarker for sepsis severity and prognosis. Material and methods Our study investigates the utility of NLR in the diagnostic strategies for urosepsis-associated delirium in a cohort of 76 patients with sepsis and septic shock admitted to the Intensive Care Unit (ICU). We performed a single-centre retrospective observational study in the Craiova Clinical Emergency Hospital between June and October 2023. Results Patients with urological conditions that were diagnosed with urosepsis included 76 patients. These patients were clustered as follows: a group with delirium (37 patients, 48.7%) and another group without delirium (39 patients, 51.3%). Complete blood count parameters were obtained upon admission, and delirium was assessed using standardized diagnostic criteria. We identified a strong significant positive correlation between elevated NLR values on ICU admission and the development of delirium during hospitalization in urosepsis patients. Receiver operating characteristic (ROC) analysis showed similar diagnostic performance for NLR score. Conclusions The findings suggest that NLR may serve as a valuable biomarker for early detection, risk stratification, and guiding therapeutic interventions in urosepsis-associated delirium, thus improving outcomes in critically ill patients.

Clinical usefulness of presepsin and monocyte distribution width (MDW) kinetic for predicting mortality in critically ill patients in intensive care unit. Front Med (Lausanne) 2024; 11:1393843. [PMID: 38831992 PMCID: PMC11144889 DOI: 10.3389/fmed.2024.1393843] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/29/2024] [Accepted: 05/02/2024] [Indexed: 06/05/2024] Open
Abstract
Background In this study, we explored the accuracy of two new sepsis biomarkers, monocyte distribution width (MDW) and presepsin (PSP), compared to traditional ones, C-reactive protein (CRP) and Procalcitonin (PCT), to identify sepsis and predict intra-hospital mortality by analyzing their kinetic at different time points during hospitalization stay. Methods We enrolled 104 patients admitted to the intensive care unit (ICU) of University Hospital "Paolo Giaccone", Palermo. Among these, 30 (29%) had a clinical diagnosis of sepsis. MDW, PCT, CRP, and PSP were evaluated at admission (T0), after 24 h (T24), 48 h (T48), 72 h (T72), at day 5 (T5), and at discharge (TD). Results Patients with sepsis displayed higher levels of PCT and PSP than patients without sepsis at each timepoint; differently, CRP displayed statistically significant differences only at T0, while MDW only at T0 and T24. Patients with increasing levels of PSP displayed lower median survival time than patients with decreasing levels; differences reached statistical significance only at 48 h (20 vs. 29 days, log rank test, p = 0.046). Interestingly, PSP was an independent predictor of ICU mortality at 48 and 72 h after hospital admission. Also, the kinetic of PSP had prognostic value, with increased values at 48 h after admission being associated with reduced survival. Conclusion Our findings support the role of PSP and its kinetic as a predictor of ICU mortality.

Abstract
Background Early diagnosis of sepsis is essential for a favorable disease outcome. The aim of this study was to evaluate the association of initial and subsequent presepsin concentrations with sepsis outcomes. Methods One hundred sepsis patients were enrolled in the study from two different university centers. Four times during study, concentrations of presepsin, procalcitonin (PCT), and C-reactive protein (CRP) were measured, and Sequential Organ Failure Assessment (SOFA) score and Acute Physiology and Chronic Health Evaluation (APACHE II) score were calculated. Patients were grouped into survivors and nonsurvivors. A sandwich ELISA kit was used to measure presepsin concentrations. To test the changes in biomarkers concentrations and SOFA score and APACHE II score during the disease course and to estimate the differences between outcome groups, generalized linear mixed effects model was used. Receiver operating characteristic curve analysis was performed to determine the prognostic value of presepsin concentrations. Results Initial values of presepsin, SOFA score, and APACHE II score were significantly higher in nonsurvivors compared to survivors. Concentrations of PCT and CRP did not differ significantly between outcome groups. ROC curve analyses show a greater predictive ability of initial presepsin concentrations for predicting mortality compared to subsequent measurements of presepsin concentrations. Conclusions Presepsin has a good ability to predict mortality. Initial presepsin concentrations better reflects poor disease outcome compared to presepsin concentrations 24 and 72 hours after admission.

Abstract
BACKGROUND Sepsis diagnosis and management is aided by the use of newer biomarkers like procalcitonin and presepsin. For prognostication, presepsin may be better than procalcitonin. METHODOLOGY Ninety-two participants, suspected to be suffering from sepsis of varied etiologies were included in this study at the time of their presentation to the emergency health services. Presepsin and procalcitonin were estimated and the patient followed up till discharge or death. Receiver operating curve (ROC) curves, sensitivity, specificity, and positive and negative likelihood ratios were calculated. Association between these markers and mortality was estimated. RESULTS Out of 92 participants enrolled on day 1, 73 survived till day 3. Patients who had thrombocytopenia, high neutrophil counts, and elevated levels of bilirubin, urea, presepsin, and procalcitonin were associated with poor outcomes. Presepsin and procalcitonin levels increased significantly from day 0 to day 3 in the nonsurvivor group as compared to the survivor group. On comparing the ROC curve of presepsin and procalcitonin, the area under the curve (AUC) of presepsin was more than procalcitonin, signifying that it was a better biomarker of mortality due to sepsis. At a cutoff value of 1.47 ng/dL, presepsin was a predictor of mortality in sepsis [odds ratio (OR) = 14]. It had similar sensitivity but better specificity than procalcitonin in predicting mortality.

Abstract
Background Analytical evaluation of newly developed presepsin by a Sysmex HISCL‐5000 (Sysmex, Japan) automated immune analyzer was performed. Methods For evaluation, sepsis patient samples were collected before treatment in an emergency department. Precision, linearity, limit of blank/limit of detection, method comparisons, and reference intervals were evaluated. Method comparisons were performed using a PATHFAST immune analyzer (LSI Medience Corporation, Japan). Results Precision using a 20x2x2 protocol for low (306 pg/mL) and high (1031 pg/mL) levels resulted in within‐laboratory standard deviation (95% confidence interval [CI]) and coefficient of variation (CV) %, which were as follows: 15.3 (13.1–18.7), 5.5% and 47.7, (40.5–58.1), 6.4%, respectively. Linearity using patient samples and calibrators were measured from 201 to 16,177 and 188 to 30,000 pg/mL, respectively. The regression equation was y = −23.2 + 1.008x (SE = 162.4) for low levels and y = 779.9 + 1.006x (SE = 668) for high levels. Method comparison by Passing–Bablock analysis was as follows: y = −209.77 + 1.047x (Syx = 335.3). The correlation coefficient (95% CI) was 0.869 (0.772–0.927) with statistical significance (p < 0.001). Reference intervals from 120 normal healthy subjects showed that 300 pg/mL was the cut off. Presepsin tended to show a higher value at higher ages and in males. Presepsin showed correlation with some parameters, and the correlation coefficient (p value) were as follows: hematocrit, 0.198 (0.03); eGFR (CKD‐EPI), −0.240 (0.0129); MDRD‐eGFR, −0.194 (0.048), respectively. Conclusion Presepsin measurement by HISCL‐5000 showed reliable performance. Further clinical studies are required for the diagnosis and prognosis of sepsis.

Abstract
Perinatal sepsis constitutes a medical emergency and is still one of the major causes of mortality and morbidity. The possibility of an early diagnosis of sepsis is still debated and controversial. In particular, clinical symptoms can be hidden by the association of sepsis with other perinatal diseases and/or by therapeutic strategies performed. In this context, there is evidence that the accuracy of standard of care diagnostic parameters (i.e. blood culture, C-reactive protein, procalcitonin) can be biased by additional confounding factors (gestational age, birth-weight, acute-chronic hypoxia). Therefore, the inclusion in clinical daily practice of new biomarkers of sepsis is of utmost importance. Of a panel of biomarkers, Presepsin (P-SEP) plays an important role in the development and response of the immune system and as an early marker of sepsis both in adult and pediatric patients. Therefore, in the present review we aim to offer an overview of the role of P-SEP in the early detection of perinatal sepsis as a trustworthy marker according to actual statements of official international institutions. Future perspectives regard the possibility of a longitudinal non-invasive biological fluids P-SEP assessment thus limiting the sample stress in high risk newborns.

Neutrophil to Lymphocyte Ratio (NLR)—A Useful Tool for the Prognosis of Sepsis in the ICU. Biomedicines 2021; 10:biomedicines10010075.

Abstract
Sepsis is a life-threatening medical emergency induced by the body′s extreme response to an infection. Despite well-defined and constantly updated criteria for diagnosing sepsis, it is still underdiagnosed worldwide. Among various markers studied over time, the neutrophil to lymphocyte ratio (NLR) recently emerged as a good marker to predict sepsis severity. Our study was a single-center prospective observational study performed in our ICU and included 114 patients admitted for sepsis or septic shock. Neutrophil to lymphocyte ratio (NLR) is easy to perform, CBC being one of the standard blood tests routinely performed upon admission for all ICU patients. We found that NLR was increased in all patients with sepsis and significantly raised in those with septic shock. NLR correlates significantly with sepsis severity evaluated by the SOFA score (R = 0.65) and also with extensively studied sepsis prognosis marker presepsin (R = 0.56). Additionally, NLR showed good sensitivity (47%) and specificity (78%) with AUC = 0.631 (p < 0.05). NLR is less expensive and easier to perform compared with other specific markers and may potentially become a good alternate option for evaluation of sepsis severity. Larger studies are needed in the future to demonstrate the prognosis value of NLR.

Abstract
BACKGROUND Acute cholangitis is caused by bacterial infection and has high morbidity and mortality risk. The grade of cholangitis can guide clinical treatment from single antibiotic treatment to biliary drainage. With the introduction of white blood cell (WBC) count, C-reactive protein (CRP), and total bilirubin (T-Bil) into the diagnostic criteria and severity grading for acute cholangitis, the diagnosis rate and grading have significantly improved. However, early risk stratification assessments are challenging in the emergency department. Therefore, we hope to find an ideal predictive biomarker for cholangitis grade. Presepsin is a promising biomarker for the early diagnosis, severity, and prognosis of acute bacterial infections.
AIM To assess the grading value of presepsin in patients with acute cholangitis.
METHODS This clinical study was conducted at the Beijing Friendship Hospital, a 2000-bed teaching hospital with approximately 200000 emergency admissions per year. In this prospective observational study, 336 patients with acute cholangitis meeting the Tokyo Guidelines 2018 diagnostic criteria in the emergency department from May 2019 to December 2020 were analyzed. WBC count, CRP, procalcitonin (PCT), presepsin, T-Bil, and blood culture results were collected. The values were compared using the Pearson χ2 test, Fisher’s exact test, or Mann-Whitney U test. The area under the receiver operating characteristic curve (AUC) of the value was examined using the Delong test. The correlations among the key research indicators were determined using Pearson correlation.
RESULTS In total, 336 patients were examined, which included 107, 106, and 123 patients classified as having mild, moderate, and severe cholangitis, respectively. WBC count, CRP, PCT, presepsin, T-Bil, direct bilirubin, and sequential organ failure assessment scores of moderate and severe cholangitis patients were higher than those of mild cholangitis patients (P = 0.000). The AUC of presepsin in predicting moderate acute cholangitis was 0.728, which was higher than that of CRP (0.631, P = 0.043) and PCT (0.585, P = 0.002), and same as that of WBC count (0.746, P = 0.713) and T-Bil (0.686, P = 0.361). The AUC of presepsin in predicting severe acute cholangitis was 0.715, which was higher than that of WBC count (0.571, P = 0.008), CRP (0.590, P = 0.009), PCT (0.618, P = 0.024), and T-Bil (0.559, P = 0.006). The presepsin levels in the positive blood culture group were higher (2830.8pg/mLvs1987.8pg/mL, P = 0.000), and the AUC of presepsin (0.688) proved that it was a good biomarker for predicting positive bacterial culture.
CONCLUSION Presepsin can predict positive blood culture in patients with acute cholangitis. It is superior to WBC count, CRP, PCT, and T-Bil for the risk stratification of acute cholangitis.

Lemierre's Syndrome: Case Presentation of a Rare and Possibly Life-Threatening Condition. MEDICINA-LITHUANIA 2021; 57:medicina57101102. [PMID: 34684139 PMCID: PMC8537463 DOI: 10.3390/medicina57101102] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/04/2021] [Revised: 10/01/2021] [Accepted: 10/12/2021] [Indexed: 11/23/2022]
Abstract
Lemierre’s syndrome is, presently, a very rare condition, but a life-threatening one. The syndrome was first described in 1936 by Andre Lemierre and comprises an oropharyngeal infection (most commonly associated with anaerobic bacteria Fusobacterium necrophorum), internal jugular vein thrombophlebitis and, possibly, secondary septic metastasis (common sites are lungs or brain). We describe such a rare case diagnosed at our Infectious Diseases Department in September 2019.

Infect Drug Resist 2021; 14:2901-2909. [PMID: 34349525 PMCID: PMC8326282 DOI: 10.2147/idr.s325635] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2021] [Accepted: 07/20/2021] [Indexed: 01/11/2023] Open
Abstract
Aim To evaluate the diagnostic and prognostic value of CSF presepsin levels in patients with postneurosurgical ventriculitis/meningitis (PNVM). Methods We conducted a case-control study to achieve our aims. First, we prospectively enrolled patients who had undergone neurosurgery in Beijing Tiantan Hospital from June to November 2020 and measured the CSF levels of 8 biomarkers, including presepsin and other meningitis biomarkers. The diagnostic and prognostic accuracies of presepsin levels were evaluated by determining the values for the area under the receiver operating characteristic curve (AUC). Results Two hundred thirty-nine patients were enrolled in this study; 34 were diagnosed with confirmed ventriculitis/meningitis (cVM), 138 were classified as probable ventriculitis/meningitis (pVM), and the others were rejected ventriculitis/meningitis (rVM). Presepsin levels effectively diagnose cVM and predict the outcomes of patients with PNVM, with thresholds of 1257.4 pg/mL and 1276.2 pg/mL and AUCs of 0.746 and 0.825, respectively. Furthermore, a joint analysis with CSF lactate (C-Lac) levels shows that the AUCs of the two markers increased to 0.856 and 0.872, respectively. Conclusion The rapid diagnosis and prediction of the clinical outcome is important in neurosurgery. CSF presepsin levels are an impressive diagnostic and prognostic biomarker for meningitis, and when combined with C-Lac, they indeed improve the diagnostic and predictive efficiency of PNVM.

Human Anthrax in Dolj County, Romania-A Series of Three Cases. Pathogens 2021; 10:pathogens10060644. [PMID: 34071062 PMCID: PMC8224695 DOI: 10.3390/pathogens10060644] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2021] [Revised: 05/16/2021] [Accepted: 05/21/2021] [Indexed: 12/03/2022] Open
Abstract
Bacillus anthracis is the causative agent of anthrax, primarily a disease of herbivorous animals, which can be accidentally transmitted to humans. Three cases of cutaneous human anthrax were recorded in August 2020 in Dolj county, Romania. These cases included livestock farmers (husband and wife, as well as a man from their entourage). The women presented malignant edema, which required surgery for compartment syndrome; and the men presented the common form of cutaneous anthrax. According to the laboratory investigation, two cases complied with the criteria in the case definition. All cases were successfully treated with antibiotics and the women received reconstructive plastic surgery of the skin defects, restoring normal hand function. The contact with sick animals was ruled out by the health authorities concluding that it was the contamination of pre-existing skin lesions with B. anthracis spores from the soil, the anthracogenic area.
