Effect of calcitriol supplementation on infectious biomarkers in patients with positive systemic inflammatory response: A Randomized Controlled Trial. Ann Med Surg (Lond) 2024; 86:875-880. [PMID: 38333320 PMCID: PMC10849351 DOI: 10.1097/ms9.0000000000001643] [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: 04/03/2023] [Accepted: 12/10/2023] [Indexed: 02/10/2024] Open
Abstract
Background Sepsis is one of the common causes of hospitalization of patients in intensive care units. A significant role for vitamin D in sepsis has been proposed, which is due to its active metabolite, calcitriol. Aims Evaluate the effect of calcitriol supplementation on infectious biomarkers, including procalcitonin and presepsin. Methods Patients with sepsis were divided into intervention and control group. Patients in the intervention group received intravenous calcitriol daily for 3 days. The serum levels of procalcitonin and presepsin were evaluated on days 0, 3, and 5 after administration. Results Fifty-two SIRS-positive patients were evaluated. Baseline characteristics, changes in Sequential Organ Failure Assessment (SOFA) score and blood levels of vitamin D were not significantly different between the two groups. Procalcitonin levels on day 5 and the differences between day 5 and 0 were significantly lower in the intervention group (P = 0.02). Presepsin on the third and fifth days in the intervention group was reduced, but in the control group, there was an ascending trend. However, there was no significant difference between the two groups on days 3 and 5 (P = 0.17 and P = 0.06, respectively) or between days 3 as well as 5 and the baseline presepsin level (P = 0.93 and P = 0.92, respectively). The ICU length of stay and 28-day mortality did not differ significantly either between the two arms of the study. Conclusions Finally, the results of this study showed that the administration of intravenous calcitriol could reduce the levels of procalcitonin but did not have a significant effect on presepsin.

J Anaesthesiol Clin Pharmacol 2023; 39:458-462. [PMID: 38025554 PMCID: PMC10661623 DOI: 10.4103/joacp.joacp_560_21] [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: 12/29/2021] [Revised: 01/18/2022] [Accepted: 02/08/2022] [Indexed: 12/01/2023] Open
Abstract
Background and Aims Mortality associated with sepsis continues to remain high. Early diagnosis and aggressive management may improve outcomes. Biomarkers may help in early diagnosis, but the search for an ideal biomarker continues. Presepsin has been introduced as a new biomarker, however, it still needs validation before its use becomes routine. In this study, we aimed to compare the efficacy of various biomarkers in patients with suspected sepsis. Material and Methods A retrospective analysis of 100 patients with suspected infection, admitted in the medical intensive care unit (ICU) was conducted. Diagnosis of sepsis was made on the basis of the current surviving sepsis guidelines criteria. Results Out of 100 patients, 70 were diagnosed to have sepsis, and overall ICU mortality was 22%. Overall, C-reactive protein (CRP) was positive in 98, procalcitonin in 75, and presepsin in 64 patients. For diagnosis of sepsis the sensitivity, specificity, and AUC, respectively, for CRP was 98.6%, 3.3%, and 0.725. For procalcitonin (>0.5 ng/ml) it was 87.1%, 53.3%, and 0.776, and for procalcitonin (>1 ng/ml) 70%, 70%, and 0.816, respectively. For presepsin sensitivity, specificity, and AUC, respectively, for diagnosis of sepsis was 77.1%, 66.7%, and 0.734. For ICU mortality, sensitivity and specificity for CRP was 95.5% and 1.3%, for procalcitonin (>0.5) 72.7% and 24.4.%, for procalcitonin (>1) 59.1% and 42.3%, and for presepsin 61.5% and 27.3%, respectively. Conclusion Inflammatory markers may be raised in a large proportion of ICU patients, even in those without sepsis. Procalcitnonin and presepsin had similar efficacy in diagnosing sepsis. However, none of the three biomarkers studied were accurate in predicting ICU mortality.

Effects of Fluids on the Sublingual Microcirculation in Sepsis. J Clin Med 2022; 11:jcm11247277. [PMID: 36555895 PMCID: PMC9786137 DOI: 10.3390/jcm11247277] [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: 11/15/2022] [Revised: 12/02/2022] [Accepted: 12/06/2022] [Indexed: 12/13/2022] Open
Abstract
Sepsis is one of the most common and deadly syndromes faced in Intensive Care settings globally. Recent advances in bedside imaging have defined the changes in the microcirculation in sepsis. One of the most advocated interventions for sepsis is fluid therapy. Whether or not fluid bolus affects the microcirculation in sepsis has not been fully addressed in the literature. This systematic review of the evidence aims to collate studies examining the microcirculatory outcomes after a fluid bolus in patients with sepsis. We will assimilate the evidence for using handheld intra vital microscopes to guide fluid resuscitation and the effect of fluid bolus on the sublingual microcirculation in patients with sepsis and septic shock. We conducted a systematic search of Embase, CENTRAL and Medline (PubMed) using combinations of the terms "microcirculation" AND "fluid" OR "fluid resuscitation" OR "fluid bolus" AND "sepsis" OR "septic shock". We found 3376 potentially relevant studies. Fifteen studies published between 2007 and 2021 fulfilled eligibility criteria to be included in analysis. The total number of participants was 813; we included six randomized controlled trials and nine non-randomized, prospective observational studies. Ninety percent used Sidestream Dark Field microscopy to examine the microcirculation and 50% used Hydroxyethyl Starch as their resuscitation fluid. There were no clear effects of fluid on the microcirculation parameters. There was too much heterogeneity between studies and methodology to perform meta-analysis. Studies identified heterogeneity of affect in the sepsis population, which could mean that current clinical classifications were not able to identify different microcirculation characteristics. Use of microcirculation as a clinical endpoint in sepsis could help to define sepsis phenotypes. More research into the effects of different resuscitation fluids on the microcirculation is needed.

Transcutaneous oxygen pressure-related variables as noninvasive indicators of low lactate clearance in sepsis patients after resuscitation. J Clin Monit Comput 2020; 35:435-442. [PMID: 32965558 DOI: 10.1007/s10877-020-00594-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2020] [Accepted: 09/18/2020] [Indexed: 12/30/2022]
Abstract
The transcutaneous oxygen challenge test (OCT) is associated with central venous oxygen saturation and cardiac output index, and has predictive value for prognosis. Whether the change of transcutaneous oxygen pressure (PtcO2)-related variables can reflect lactate clearance in sepsis patients is worth studying. We conducted a prospective observational study of 79 patients with sepsis or septic shock in the ICU. Immediately after enrollment, PtcO2 monitoring was continuously performed for 6 h. The OCT was performed at enrollment (T0) and the sixth hour (T6). The correlation between lactate clearance and PtcO2-related variables such as PtcO2 at T6, ΔPtcO2 (PtcO2 at T6 - PtcO2 at T0), ΔPtcO2 index (PtcO2/PaO2 at T6 - PtcO2/PaO2 at T0), 10 OCT [(PtcO2 after 10 min on FiO2 of 1.0) - (PtcO2 at baseline)], Δ10 OCT (10 OCT at T6 - 10 OCT at T0) was analyzed. The difference of PtcO2-related variables was compared between the high and low lactate clearance groups. PtcO2 at T6 (r = 0.477, p < 0.001), ΔPtcO2 (r = 0.592, p < 0.001), ΔPtcO2 index (r = 0.553, p < 0.001) and Δ10 OCT (r = 0.379, p = 0.001) were significantly correlated with the lactate clearance. To discriminate low lactate clearance, the area under the ROC curve was largest for ΔPtcO2, which was 0.804. PtcO2 at T6, PtcO2 index, ΔPtcO2, ΔPtcO2 index and Δ10 OCT were significantly different between the two different lactate clearance groups. Low lactate clearance in the initial 6 h of resuscitation of septic shock was associated to lower improvements in PtcO2-related variables.

Relationship between Microcirculatory Perfusion and Arterial Elastance: A Pilot Study. Crit Care Res Pract 2019; 2019:3256313. [PMID: 31049225 PMCID: PMC6458893 DOI: 10.1155/2019/3256313] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2018] [Revised: 02/26/2019] [Accepted: 03/10/2019] [Indexed: 01/20/2023] Open
Abstract
Background Arterial elastance (Ea) represents the total afterload imposed on the left ventricle, and it is largely influenced by systemic vascular resistance (SVR). Although one can expect that Ea is influenced by peripheral endothelial function, no data are available to support it in patients. The aim of this study was to investigate the relationship between Ea, SVR, and microvascular perfusion in critically ill patients undergoing the fluid challenge (FC). Methods A prospective study in patients receiving a fluid challenge. A pulse wave analysis system (MostCare, Vygon, France) was used to estimate Ea and an incident dark field (IDF) handheld device (Braedius Medical BV, The Netherlands) to evaluate the sublingual microcirculation. Microvascular perfusion was assessed using the proportion of small-perfused vessels (PPV). Relative changes in each variable were calculated before and after FC; fluid responsiveness was defined as an increase in the cardiac index by at least 10% from baseline. Results We studied 20 patients requiring a fluid challenge (n=10 for hypotension; n=5 for oliguria; n=3 for lactate values greater than 2 mmol/l; n=2 for tachycardia), including 12 fluid responders. There was a strong correlation between Ea and SVR (r2 = 0.75; p < 0.001) and only a weak correlation between Ea and PPV at baseline (r2 = 0.22; p=0.04). Ea decreased from 1.4 [1.2–1.6] to 1.2 [1.1–1.4] mmHg/mL (p=0.01), SVR from 1207 [1006–1373] to 1073 [997–1202] dyn ∗ s/cm5 (p=0.06), and PPV from 56 [51–64] % to 59 [47–73] % (p=0.25) after fluid challenge. Changes in Ea were significantly correlated with changes in SVR, but not with changes in PPV. Conclusions The correlation between Ea and indexes of microvascular perfusion in the sublingual region is weak. The impact of microcirculatory perfusion on the arterial load is probably limited.

Abstract
Background The soluble cluster of differentiation 14 (or presepsin) is a free fragment of glycoprotein expressed on monocytes and macrophages. Although many studies have been conducted recently, the diagnostic performance of presepsin for sepsis remains debated. We performed a systematic review and meta-analysis of the available literature to assess the accuracy of presepsin for the diagnosis of sepsis in adult patients and compared the performance between presepsin, C-reactive protein (CRP), and procalcitonin (PCT). Methods A comprehensive systemic search was conducted in PubMed, EMBASE, and Google Scholar for studies that evaluated the diagnostic accuracy of presepsin for sepsis until January 2017. The hierarchical summary receiver operating characteristic method was used to pool individual sensitivity, specificity, diagnostic odds ratio (DOR), positive likelihood ratio (PLR), negative likelihood ratio (NLR), and area under the receiver operating characteristic curve (AUC). Results Eighteen studies, comprising 3470 patients, met our inclusion criteria. The pooled diagnosis sensitivity and specificity of presepsin for sepsis were 0.84 (95% CI 0.80–0.87) and 0.76 (95% CI 0.67–0.82), respectively. Furthermore, the pooled DOR, PLR, NLR, and AUC were 16 (95% CI 10–25), 3.4 (95% CI 2.5–4.6), 0.22 (95% CI 0.17–0.27), and 0.88 (95% CI 0.85–0.90), respectively. Significant heterogeneity was found in both sensitivities (Cochrane Q = 137.43, p < 0.001, I2 = 87.63%) and specificities (Cochrane Q = 180.76, p < 0.001, I2 = 90.60%). Additionally, we found no significant difference between presepsin and PCT (AUC 0.87 vs. 0.86) or CRP (AUC 0.85 vs. 0.85). However, for studies conducted in ICU, the pooled sensitivity of presepsin was found to be higher than PCT (0.88, 95% CI 0.82–0.92 vs. 0.75, 95% CI 0.68–0.81), while the pooled specificity of presepsin was lower than PCT (0.58, 95% CI 0.42–0.73 vs. 0.75, 95% CI 0.65–0.83). Conclusion Based on the results of our meta-analysis, presepsin is a promising marker for diagnosis of sepsis as PCT or CRP, but its results should be interpreted more carefully and cautiously since too few studies were included and those studies had high heterogeneity between them. In addition, continuing re-evaluation during the course of sepsis is advisable.

Abstract
The microcirculation is the anatomical location of perfusion and substrate exchange, and its functional impairment is of paramount importance during the state of shock. The difference in venous-to-arterial carbon dioxide partial pressures (Pv-aCO2) has recently been reported to correlate with microcirculatory dysfunction during early septic shock with greater fidelity than global hemodynamic parameters. This makes it a potential candidate as a point-of-care test in goal directed therapy that aims to restore microcirculatory function in an emergency clinical context. This early work needs to be explored further, and a better understanding of Pv-aCO2 during the resuscitation and subsequent patient progression is required. The quest for an ideal bedside point-of-care test for microcirculatory behavior is ongoing, and is likely to consist of a combination of non-invasive sublingual microcirculatory monitoring and biochemical tests that reflect tissue perfusion. These tools have the potential to provide more accurate and clinically relevant data with regards to the microcirculation that more conventional resuscitative monitoring such as blood pressure, cardiac output, and serum lactate.

Abstract
BACKGROUND In 2004, a new biomarker sCD14-subtypes (presepsin) was found and its value was shown in the diagnosis and evaluation of sepsis. This article is a brief overview of the new biomarker. DATA SOURCES A literature search using multiple databases was performed for articles, especially meta-analyses, systematic reviews, and randomized controlled trials. RESULTS Compared with other markers, presepsin seems to have a better sensitivity and specificity in the diagnosis of sepsis. Presepsin as a biom1arker is not only suitable for the early diagnosis of sepsis, but also for the assessment of its severity and prognosis. CONCLUSIONS Presepsin has a higher sensitivity and specificity in the diagnosis of sepsis as a new biomarker, and is a predictor for the prognosis of sepsis. More importantly, preseptin seems to play a crucial role as a supplemental method in the early diagnosis of sepsis. Since there is no multicenter study on the relationship between presepsin and sepsis, further studies on the clinical values of presepsin are needed.
