Background: Neuron-specific enolase (NSE) and S-100B protein have been reported that they are associated with neurological outcome in out-of-hospital cardiac arrest (OHCA) survivors. However, comparing the prognostic performance between NSE and S-100B obtained from cerebrospinal fluid (CSF) has not been assessed yet. Therefore, this study aimed to investigate the prognostic performance of NSE and S-100B obtained from CSF for poor neurological outcomes in OHCA survivors. Methods: This was a prospective single-centre observational study, conducted from November 2018 to February 2019. The CSF samples of NSE and S-100B were serially obtained until 72 h from immediate as possible from return of spontaneous circulation (ROSC), at 24 h interval (NSE i , 24,48,72 and S-100B i , 24,48,72 ). The area under curves (AUCs) were used to identify the sensitivities of two biomarkers for predicting poor neurologic outcomes. The primary outcome was the 3-months neurological outcomes. Results: We enrolled 35 patients (males, 28), and 16 subjects had a poor neurologic outcome. NSE and S-100B levels were significantly higher in the poor outcome group compared to the good outcome group at each time point. The AUCs of NSE and S-100B for poor neurological outcomes were 0.87 versus 0.95 at immediately, 0.96 versus 0.92 at 24 h, 0.99 versus 0.97, and 0.98 versus 0.97 at 72 h after ROSC, respectively. The sensitivities with 100% specificity of NSE and S-100B for poor neurological outcomes were 62.5 versus 33.3 at immediate, 73.3 versus 71.4 at 24 h, 92.9 versus 92.3 at 48 h, and 91.7 versus 88.9 at 72 h after ROSC, respectively. Conclusions: S-100B can be useful for early predicting the neurological outcomes of comatose OHCA patients within 24 hours from ROSC in spite of low sensitivity, whereas NSE need 24 hours at least for prognostication. Further prospective with large sample size in multicenter studies are needed to confirm out results.

We examined whether combining biomarkers measurements and brain images early after the return of spontaneous circulation improves prognostic performance compared with the use of either biomarkers or brain images for patients with cardiac arrest following target temperature management (TTM). This retrospective observational study involved comatose out-of-hospital cardiac arrest survivors. We analyzed neuron-specific enolase levels in serum (NSE) or cerebrospinal fluid (CSF), grey-to-white matter ratio by brain computed tomography, presence of high signal intensity (HSI) in diffusion-weighted imaging (DWI), and voxel-based apparent diffusion coefficient (ADC). Of the 58 patients, 33 (56.9%) had poor neurologic outcomes. CSF NSE levels showed better prognostic performance (area under the curve (AUC) 0.873, 95% confidence interval (CI) 0.749–0.950) than serum NSE levels (AUC 0.792, 95% CI 0.644–0.888). HSI in DWI showed the best prognostic performance (AUC 0.833, 95% CI 0.711–0.919). Combining CSF NSE levels and HSI in DWI had better prognostic performance (AUC 0.925, 95% CI 0.813–0.981) than each individual method, followed by the combination of serum NSE levels and HSI on DWI and that of CSF NSE levels and the percentage of voxels of ADC (AUC 0.901, 95% CI 0.792–0.965; AUC 0.849, 95% CI 0.717–0.935, respectively). Combining CSF/serum NSE levels and HSI in DWI before TTM improved the prognostic performance compared to either each individual method or other combinations.

Circulating Levels

Outcome prognostication after cardiac arrest (CA) is challenging. Current multimodal prediction approaches would benefit from new biomarkers. MicroRNAs constitute a novel class of disease markers and circulating levels of brain-enriched ones have been associated with outcome after CA. To determine whether these levels reflect the extent of brain damage in CA patients, we assessed their correlation with neuron-specific enolase (NSE), a marker of brain damage. Blood samples taken 48 h after return of spontaneous circulation from two groups of patients from the Targeted Temperature Management trial were used. Patients were grouped depending on their neurological outcome at six months. Circulating levels of microRNAs were assessed by sequencing. NSE was measured at the same time-point. Among the 673 microRNAs detected, brain-enriched miR9-3p, miR124-3p and miR129-5p positively correlated with NSE levels (all p < 0.001). Interestingly, these correlations were absent when only the good outcome group was analyzed (p > 0.5). Moreover, these correlations were unaffected by demographic and clinical characteristics. All three microRNAs predicted neurological outcome at 6 months. Circulating levels of brain-enriched microRNAs are correlated with NSE levels and hence can reflect the extent of brain injury in patients after CA. This observation strengthens the potential of brain-enriched microRNAs to aid in outcome prognostication after CA.

Abstract Background Little is known about the effectiveness of surface cooling (SC) and endovascular cooling (EC) on the outcome of out-of-hospital cardiac arrest (OHCA) patients receiving target temperature management (TTM) according to their initial rhythm. Methods We retrospectively analysed data from the Japanese Association for Acute Medicine Out‐of‐Hospital Cardiac Arrest registry, a multicentre, prospective nationwide database in Japan. For our analysis, OHCA patients aged ≥ 18 years who were treated with TTM between June 2014 and December 2017 were included. The primary outcome was 30-day survival with favourable neurological outcome defined as a Glasgow–Pittsburgh cerebral performance category score of 1 or 2. Cooling methods were divided into the following groups: SC (ice packs, fans, air blankets, and surface gel pads) and EC (endovascular catheters and any dialysis technique). We investigated the efficacy of the two categories of cooling methods in two different patient groups divided according to their initially documented rhythm at the scene (shockable or non-shockable) using multivariable logistic regression analysis and propensity score analysis with inverse probability weighting (IPW). Results In the final analysis, 1082 patients were included. Of these, 513 (47.4%) had an initial shockable rhythm and 569 (52.6%) had an initial non-shockable rhythm. The proportion of patients with favourable neurological outcomes in SC and EC was 59.9% vs. 58.3% (264/441 vs. 42/72), and 11.8% (58/490) vs. 21.5% (17/79) in the initial shockable patients and the initial non-shockable patients, respectively. In the multivariable logistic regression analysis, differences between the two cooling methods were not observed among the initial shockable patients (adjusted odd ratio [AOR] 1.51, 95% CI 0.76–3.03), while EC was associated with better neurological outcome among the initial non-shockable patients (AOR 2.21, 95% CI 1.19–4.11). This association was constant in propensity score analysis with IPW (OR 1.40, 95% CI 0.83–2.36; OR 1.87, 95% CI 1.01–3.47 among the initial shockable and non-shockable patients, respectively). Conclusion We suggested that the use of EC was associated with better neurological outcomes in OHCA patients with initial non-shockable rhythm, but not in those with initial shockable rhythm. A TTM implementation strategy based on initial rhythm may be important.

Aim: We aimed to investigate the prognostic performance between serum NSE and cerebrospinal fluid (CSF) NSE for 6-month neurologic outcome in OHCA survivors underwent target temperature management (TTM). Hypothesis: We hypothesized that the NSE levels measured in the CSF would affect the change, earlier and more sensitively than serum, according to severity of hypoxic brain damage. Methods: This single-centre prospective observational study included out-of-hospital cardiac arrest (OHCA) patients underwent TTM. NSE levels were assessed in blood and CSF samples obtained immediately (Day 0), and 24 h (Day 1), 48 h (Day 2), and 72 h (Day 3) after return of spontaneous circulation (ROSC). The primary outcome was the 6-month neurological outcome. Results: We enrolled 34 patients (males, 24; 70.6%), 16 (47.1%) had a poor neurologic outcome. CSF NSE and serum NSE values were significantly higher in the poor outcome group compared to the good outcome group at each time point, except for serum Day 0. CSF NSE and serum NSE had area under curve (AUC) of 0.819-0.972 and 0.648-0.920, respectively. CSF NSE prognostic performances were significant higher than serum NSE at Day 1 and showed excellent AUC values (0.969; 95% Confidential Interval [CI] 0.844-0.999) and high sensitivity (93.8%; 95% CI 69.8-99.8) at 100% specificity. Conclusion: We found CSF NSE values were highly predictive and sensitive markers of 6-month poor neurological outcome in OHCA survivors treated with TTM at Day 1 after ROSC. Thus, CSF NSE level at day 1 after ROSC can be a useful early prognosticator in OHCA survivors.

Abstract Background: This study aimed to compare the day-specific association of blood–brain barrier (BBB) disruption with neurological outcomes in out-of-hospital cardiac arrest (OHCA) survivors treated with target temperature management (TTM).Methods: This retrospective single-center study included 68 OHCA survivors, who underwent TTM between April 2018 and December 2019. The albumin quotient (QA) was calculated as [albuminCSF] / [albuminserum] immediately (day 1), and at 24 h (day 2), 48 h (day 3), and 72 h (day 4) after return of spontaneous circulation (ROSC). The degree of BBB disruption was weighted using the following scoring system: 0.07 ≥ QA (normal), 0.01 ≥ QA > 0.007 (mild), 0.02 ≥ QA > 0.01 (moderate), and QA > 0.02 (severe). This system gave it 0 (normal), 1 (mild), 4 (moderate), and 9 (severe) points. Poor neurological outcome was determined at six months after ROSC and was defined as cerebral performance categories 3–5.Results: We enrolled 68 patients (males, 48; 71%); 37 (54%) of them had a poor neurological outcome. The distributions of this outcome at six months in patients with moderate and severe BBB disruption versus the other groups were 19/22 (80%) vs. 18/46 (50%) on day 1, 31/37 (79%) vs. 6/31 (32%) on day 2, 32/37 (81%) vs. 5/31 (30%) on day 3, and 32/39 (85%) vs. 5/29 (30%) on day 4 (P < 0.001). Using ROC analyses, the optimal cutoff values of QA levels for prediction of neurological outcomes were determined as: day 1, > 0.009 (sensitivity 56.8%, specificity 87.1%); day 2, > 0.012 (sensitivity 81.1%, specificity 87.1%); day 3, > 0.013 (sensitivity 83.8%, specificity 87.1%); day 4, > 0.013 (sensitivity 86.5%, specificity 87.1%); sum of all time points, > 0.039 (sensitivity 89.5%, specificity 79.4%); and scoring system, > 9 (sensitivity 91.9%, specificity 87.1%). Conclusions: Our results suggested that QA is a useful tool for predicting neurological outcomes in OHCA survivors treated with TTM. However, the prediction of poor neurological outcome using QA showed low sensitivity at 100% specificity. Thus, it could be used as part of a multimodal approach than as a single prognostic prediction tool.

Abstract Background Platelet/lymphocyte ratio (PLR), an inflammatory marker associated with poor outcomes in different clinical situations, may play a role in the proinflammatory state triggered during hypoxic-ischemic brain injury secondary to cardiac arrest. Purpose To study PLR dynamics and its relationship with neurologic outcomes in survivors after CA treated with target-temperature-management (TTM). Methods Observational retrospective study from a prospective database of survivors of in-hospital and out-of-hospital CA admitted to our Acute Cardiac Care Unit between August 2006 to December 2018. All patients received TTM according to our local protocol. Results A total of 466 patients were included. Mean age was 62.7±14.4 years and 102 (21.9%) were women. Baseline characteristics are shown in Table 1. 430 (92.2%) of CA were witnessed, 312 (67.0%) had ventricular fibrillation as initial cardiac rhythm. Among them, 236 (51.1%) survived until hospital discharge and 208 (45.1%) presented favorable neurological outcomes (a score 1 or 2 on cerebral performance category (CPC)). The mean value of PLR at admission and during targeted temperature was 100.4±5.2 and 224.5±7.3 respectively (mean difference 123.1±7.1, p<0.0001). This increase in PLR was significantly higher among patients with worse neurological outcomes (CPC 3–5, mean DPLR 138.2±5.5) at 3 months compared with survivors with CPC 1–2 (mean DPLR 108.2±6.3, p=0.0348 for paired comparison between both groups). Table 1 Hypertension, n (%) 235 (54.9) Diabetes, n (%) 113 (26.4) Dyslipidaemia, n (%) 171 (40.0) Smocking habit, n (%) 208 (48.5) Time to ROSC mean ± SD, min 26.6±18.6 Mean arterial pressure at HA mean±DS, mmHg 81.3±22.1 pH at HA mean ± SD 7.18±0.16 Lactic at HA mean ± SD 6.37±4.42 ROSC: return of spontaneus circulation; HA: hospital admission. Conclusion Our findings reflect the impact of inflammation in neurological outcomes after OHCA treated with TTM. Major increases of PLR constitute a novel marker of poor prognosis during early assessment of OHCA patients.

Purpose: Target temperature management (TTM) and extracorporeal cardiopulmonary resuscitation (ECPR) have been established as important interventions during cardiopulmonary arrest. However, the impact of combined TTM and ECPR on clinical outcomes has not been studied in detail. Methods: We reviewed the records of 245 patients who received extracorporeal life support (ECLS) between January 2012 and June 2015. Exclusion criteria were as follows: Extracorporeal life support performed for reasons other than cardiac arrest, age less than 18 years, and death within 24 hours. A total of 101 patients were finally included in the study. Twenty-five patients underwent TTM, and 76 patients did not. Results: The patients’ mean age was 55 ± 16.7 years. The mean cardiac arrest time was 44.6 ± 33.5 minutes. There were 84 patients whose cardiac arrest was due to a cardiac cause (83.2%) and 79 patients with in-hospital cardiac arrest (78.2%). There was a significant difference in average body temperature during the first 24 hours following ECPR (33.4°C vs 35.6°C; P = .001). The overall favorable neurological outcome rate was 34% and hospital survival rate was 47%. There was no difference in favorable neurological outcomes and hospital survival between the TTM and non-TTM groups ( P = .91 and .84, respectively). On multivariate analysis of neurological outcomes and hospital survival, TTM was not a significant prognostic factor. Conclusion: We did not observe any benefits of TTM in patients undergoing ECPR. Natural hypothermia or normothermia related to ECLS may explain this result. Further research is needed to understand the role of TTM in ECPR.

A TTM implementation strategy based on initial rhythm may be important.Trial registration: None
