ABSTRACT

Objective:To explore the value of neutrophil gelatinase-associated lipocalin(NGAL)and neutrophil-to-lymphocyte and platelet ratio(NLPR)for early prediction of kidney injury with Diquat(DQ)poisoning in elderly patients.Methods:In this retrospective study, a total of 106 elderly patients with DQ poisoning treated in the Emergency Intensive Care Unit(EICU)of Harrison International Peace Hospital Affiliated to Hebei Medical University between October 2019 and October 2021 were divided into an acute kidney injury group(AKI group, n=62)and a non-acute kidney injury group(NAKI group, n=44). Meanwhile, 40 non-elderly patients with DQ poisoning served as the control group.Samples of 5 ml venous blood were collected from patients admitted to the EICU to measure NGAL and NLPR levels and Logistic regression analysis was conducted to analyze independent risk factors for AKI in elderly DQ poisoning patients.The area under the curve(AUC)was calculated via the receiver operating characteristic(ROC)curve, and the value of NGAL and NLPR for early prediction of AKI in elderly patients with DQ poisoning and patient prognosis was assessed.Results:Blood NGAL and NLPR levels in the AKI group were significantly higher than in the NAKI group[(387.1±46.6)μg/L vs.(103.5±18.6)μg/L, (13.5±3.4) vs.(5.3±1.1), t=38.243, 15.608, P<0.001 for both]. Logistic regression analysis results showed that elevated levels of NGAL( OR=1.009, 95% CI: 1.003-1.015, P<0.001)and NLPR( OR=1.263, 95% CI: 1.039-1.536, P<0.001)were risk factors for AKI in elderly patients with DQ poisoning.The areas under the ROC curves of NGAL, NLPR and NGAL+ NLPR for AKI prediction were 0.834, 0.803 and 0.873 respectively.The predictive power of NGAL and NLPR for the death of elderly patients with DQ poisoning was higher than that of creatinine clearance(Ccr). The sensitivity of the combination of the two to predict the risk of death was 0.850, the specificity was 0.828, and the AUC was 0.887. Conclusions:NGAL and NLPR are independent risk factors for the occurrence of AKI in elderly patients with DQ poisoning.Combined detection of NGAL and NLPR improves AKI prediction and prognosis assessment in elderly patients with DQ poisoning.

ABSTRACT

Objective:To investigate the effect of continuous hemoperfusion (HP) on the levels of soluble CD14 isoform (sCD14-st) and neutrophil gelatinase-associated lipocalin (NGAL) on patients with diquat (DQ) poisoning and its significance.Methods:A total of 86 patients with acute DQ poisoning admitted to the department of emergency medicine, Harrison International Peace Hospital Affiliated to Hebei Medical University from May 2018 to August 2021 were enrolled and divided into the intermittent HP group (40 cases) and the continuous HP group (46 cases) according to the random number table method. All patients received basic treatment and continuous veno-venous hemofiltration (CVVH) within 24 hours after admission. On this basis, the intermittent HP group received HP treatment within 2 hours, lasting 2 hours each time for every 8 hours, 3 times in all; the continuous HP group received continued HP treatment until there was no DQ component in urine samples. Serum NGAL levels were detected in all patients before treatment and at 3 hours, 12 hours, 24 hours, 2 days, 3 days, 5 days, and 7 days after treatment. At the same time, serum sCD14-st, blood lactate (Lac), arterial partial pressure of oxygen (PaO 2), serum creatinine (SCr), MB isoenzyme of creatine kinase (CK-MB) and interleukin-18 (IL-18) levels were detected before treatment and at 24 hours, 3 days, and 7 days after treatment. Kaplan-Meier survival curve was drawn to analyze the 28-day survival of patients. Results:Before treatment, there was no significant difference in serum NGAL, sCD14-st, Lac, PaO 2, SCr, CK-MB and IL-18 levels between the two groups. With the prolongation of treatment, the serum levels of NGAL, sCD14-st, Lac, SCr, CK-MB and IL-18 in the intermittent HP group increased at first and then decreased. Serum levels of NGAL, sCD14-st, CK-MB and IL-18 reached their peaks at 24 hours after treatment, and the Lac and SCr levels reached their peaks at 3 days after treatment. In addition, the levels of the above indexes at each time point in the continuous HP group were all significantly lower than those in the intermittent HP group [after 24 hours of treatment: NGAL (μg/L) was 345.90±30.75 vs. 404.24±38.79, sCD14-st (ng/L) was 1 941.88±298.02 vs. 2 656.35±347.93, CK-MB (U/L) was 30.67±9.11 vs. 43.28±8.06, IL-18 (ng/L) was 139.49±16.29 vs. 177.98±27.85; 3 days of treatment: Lac (mmol/L) was 2.98±0.26 vs. 3.72±0.49, SCr (μmol/L) was 125.01±24.24 vs. 156.74±28.88; all P < 0.05]. However, there was no significant difference in PaO 2 levels between the two groups at each time point after treatment. The Kaplan-Meier survival curve showed that the 28-day mortality of patients in the continuous HP group was significantly lower than that in the intermittent HP group [26.09% (12/46) vs. 52.50% (21/40); Log-Rank test: χ2 = 7.288, P = 0.007]. Conclusion:Continuous HP could effectively reduce serum sCD14-st, NGAL levels and 28-day mortality in patients with DQ poisoning, with good curative effect.

ABSTRACT

Objectives:To investigate the relationship between heart rate adjusted QT dispersion (QTcd) and soluble growth stimulating gene 2 protein (sST2) and the severity and prognosis of patients with acute carbon monoxide toxic heart disease.Methods:Retrospective analysis was performed on 135 patients with acute carbon monoxide toxic heart disease admitted to the Emergency Medical Department of our hospital from January 2017 to 2020. Blood sST2, creatine kinase isoenzyme (CK-MB) and troponin I(cTnI) concentrations were recorded at 3 h, 12 h, 2 d and 3 d immediately after admission.The patient was measured and calculated on the day of admission,2 d,3 d and QTcd at discharge.According to the toxicity of carbon monoxide in heart disease severity was divided into mild heart disease group (58 cases), moderate heart disease group (45 cases), severe heart disease group (32 cases), according to whether severe heart disease were divided into severe group (32 cases) and non severe group (103 cases), according to whether the patients death in patients with severe heart disease.Results:Thirty-two of the 135 patients had severe toxic heart disease, with an incidence of 23.7%.In the severe group, sST2, cTnI and CK-MB increased from 24 h and 2 d after admission, and the detected values were all higher than those of the non-severe group and the normal control group, with statistically significant differences ( P<0.05).Before treatment, there were statistically significant differences in sST2 and QTcd between the toxic group and the non-severe group and the normal control group ( P<0.05).After 2 d and 3 d poisoning, there were statistically significant differences between the two groups ( P<0.05). ROC curve analysis showed that the area under the sST2 curve was 0.726, 95% CI was 0.555-0.898, sensitivity was 56.3%, specificity was 94.1%, and truncation was 88.5 ng/mL.The area under the QTcd curve was 0.745, 95% CI was 0.602-0.889, sensitivity was 56.3%, specificity was 82.4%, and truncation value was 68.5 ms.The area under the combined detection curve was 0.939, 95% CI was 0.874-1.000, sensitivity was 81.3%, specificity was 91.2%. Conclusions:In patients with acute carbon monoxide toxic heart disease, the level of sST2 increased earlier than THAT of cTnI and CK-MB, and the combined observation of sST2 and QTcd can be used as an indicator for early prediction of acute carbon monoxide toxic heart disease and its severity.

ABSTRACT

Objective:To investigate the clinical significance of soluble growth stimulating expression gene 2 protein (sST2) combined with neutrophil/lymphocyte ratio (NLR) in the prediction of nosocomial cardiovascular adverse events in patients with acute carbon monoxide poisoning (ACOP) myocardial injury.Methods:Patients with ACOP myocardial injury from January 2017 to December 2019 in Emergency Ward and EICU of Harrson International Peace Hospital, Hebei Medical University were enrolled. NLR was calculated by routine blood examination on admission, and sST2 (T 0sST2, T 3dsST2) was detected by ELISA on admission and at 3 days after admission. According to the occurrence of cardiovascular adverse events, the patients were divided into the event group and the non-event group. Logistic regression was used to analyze the risk factors of in-hospital cardiovascular adverse events. ROC curve was used to analyze the value of sST2, NLR, sST2 and NLR combined in predicting the occurrence of in-hospital cardiovascular adverse events in patients with ACOP myocardial injury. Results:Totally 255 patients with ACOP myocardial injury were included in the final analysis. NLR was (13.38±4.33) in the event group and (9.57±4.22) in the non-event group, T 3dsST2 was (61.59±22.67) ng/mL in the event group and (40.52±13.14) ng/mL in the non-event group, with statistically significant differences (all P<0.01). T 0sST2 was (265.34±89.95) ng/mL in the event group and (242.43±93.09) ng/mL in the non-event group, with no statistically significant difference ( P=0.333). Logistic regression analysis showed that NLR ( OR=1.270, 95% CI: 1.125-1.434, P<0.01) and T 3dsST2 ( OR=1.082, 95% CI: 1.052-1.114, P<0.01) were independent risk factors for nosocomial cardiovascular adverse events in patients with ACOP myocardial injury. The optimal cutoff value of T 3dsST2 was 44.5 ng/mL, and of NLR was 12.08. The sensitivity and specificity of dual T 3dsST2 and NLR in predicting nosocomial cardiovascular adverse events was 79.3% and 82.7%, respectively (AUC 0.857, Youden index 0.620). Conclusions:T 3dsST2 and NLR are independent risk factors for the nosocomial cardiovascular adverse events in patients with ACOP myocardial injury. The predictive cutoff values are 44.5 ng/mL for T 3dsST2 and 12.08 for NLR. Combination of T 3dsST2 and NLR has a practical predictive value for nosocomial cardiovascular adverse events in patients with ACOP myocardial injury.

ABSTRACT

Objective:To investigate the predictive neutrophil/lymphocyte ratio (NLR) combined with soluble growth stimulating expression gene 2 protein (sST2) on in-hospital major adverse cardiovascular events (MACE) in patients with myocardial injury following moderate-severe acute carbon monoxide poisoning (ACOP).Methods:A single-cente prospective observational approach was conducted. Moderate-severe ACOP patients with myocardial damage from November 2016 to February 2020 in department of emergency medicine of Harrison International Peace Hospital Affiliated to Hebei Medical University were enrolled. The baseline data of the patients, NLR and sST2 (T0 sST2) on admission, sST2 at 3 days after admission (T3 d sST2), and the other myocardial injury and biochemical indicators were collected. According to whether MACE occurred, the patients were divided into MACE group and non-MACE group. The clinical data of the two groups were compared. Pearson correlation analysis was used to analyze the correlation of each index. Binary Logistic regression was used to analyze the independent risk factors of in-hospital MACE in patients with moderate-severe ACOP myocardial injury. The receiver operator characteristic curve (ROC curve) was drawn and area under ROC curve (AUC) was calculated to analyze the predictive value of NLR, sST2, and NLR combined with sST2 for the occurrence of in-hospital MACE in patients with moderate-severe ACOP myocardial injury.Results:A total of 278 patients with moderate-severe ACOP myocardial injury were included in the final analysis, and the incidence of MACE was 11.51% (32/278). Cardiac troponin I (cTnI), lactic acid (Lac), NLR, and T3 d sST2 in the MACE group were significantly higher than those in the non-MACE group [cTnI (μg/L): 0.83±0.15 vs. 0.46±0.37, Lac (mmol/L): 2.96±1.14 vs. 2.43±1.35, NLR: 13.14±4.37 vs. 9.49±4.21, T3 d sST2 (μg/L): 59.88±23.42 vs. 39.83±12.60, all P < 0.05], there was no significant difference in T0 sST2 between the MACE group and the non-MACE group (μg/L: 269.09±90.89 vs. 240.14±113.02, P > 0.05). Pearson correlation analysis showed that there were significantly positive correlations in NLR with acute physiology and chronic health evaluationⅡ(APACHEⅡ), T3 d sST2 with APACHEⅡ, and NLR with T3 d sST2 ( r values were 0.226, 0.209, 0.193, all P < 0.01). Binary Logistic regression analysis showed that T3 d sST2 and NLR were both independent risk factors for MACE in moderate-severe ACOP patients with myocardial injury [odds ratio ( OR) and 95% confidence interval (95% CI) respectively was 1.064 (1.039-1.090), 1.176 (1.066-1.298), both P < 0.01]. ROC curve analysis showed that the predictive efficacy of NLR combined with T3 d sST2 for the occurrence of in-hospital MACE in patients with ACOP myocardial injury (AUC = 0.876) was better than that of NLR (AUC = 0.754) and T3 d sST2 (AUC = 0.813). When the optimal critical value of NLR was 10.02 and that of T3 d sST2 was 43.50 μg/L, the sensitivity of predicting the occurrence of MACE in patients with moderate-severe ACOP myocardial injury was 69.8% and 86.2% respectively, and the specificity was 74.3% and 70.4%, respectively. The specificity and sensitivity of the combined detection was 83.4% and 79.8%, respectively. Conclusions:NLR and T3 d sST2 were independent predictors of in-hospital MACE in moderate-severe ACOP patients with myocardial injury, and combined application of NLR and T3 d sST2 had good predictive value. For patients with moderate-severe ACOP myocardial injury with NLR > 10.02 and T3 d sST2 > 43.50 μg/L, the occurrence of in-hospital MACE should be alert.

ABSTRACT

Objective:To investigate clinical value of early cerebral oxygen utilization(O 2UCc)combined with the bispectral index(BIS)for monitoring delayed encephalopathy after acute carbon monoxide poisoning(DEACMP)in elderly patients. Methods:This was a retrospective analysis.A total of 90 elderly patients with acute severe carbon monoxide poisoning(ASCMP)treated in Harrison International Peace Hospital from Nov.2018 to Jan.2020 were considered as research objects.Patients were divided into the DEACMP group(n=25)and the good prognosis group(n=65)according to their prognosis.Oxygen quantity absorbed into UCC(O 2UCc)and Bispectral index(BIS)at different times in the early stages were compared between the two groups.Correlations of O 2UCc and BIS with the occurrence of DEACMP were analyzed.Clinical significance of O 2UCc or BIS alone and of the two parameters in combination for the prediction of DEACMP was investigated. Results:O 2UCc was higher and BIS was lower in the DEACMP group than in the good prognosis group at 0 h, 6 h, 12 h, and 24 h after admission(all P<0.01). Pearson correlation analysis showed that O 2UCc was negatively correlated with DEACMP( r0 h=-0.482, r6 h=-0.534, r12 h=-0.587, r24 h=-0.514, all P<0.01), BIS was positively correlated with DEACMP( r0 h=0.348, r6 h=0.583, r12 h=0.679, r24 h=0.489, all P<0.01), and the correlation was the strongest at 12h after admission.ROC curve analysis was performed with O2UCc, BIS and the combined predictors at 12 h, and the results showed that the areas under the ROC curve of O 2UCc, BIS and the two in combination for DEACMP prediction were 0.845, 0.850 and 0.909, respectively, the sensitivities were 78.5%, 90.8% and 96.9% and the specificities were 80.0%, 76.0% and 84.0%, respectively. Conclusions:Early detection of O 2UCc or BIS has a good clinical value for predicting the development of ASCMP to DEACMP, and their combined value is even better.

ABSTRACT

Objective:The predictive value of LCR and BIS monitoring for delayed encephalopathy in acute severe carbon monoxide poisoning.Methods:Ninety-four patients with acute severe carbon monoxide poisoning treated in the Harrison International Peace Hospital Affiliated to Hebei Medical University between January 2017 and March 2019 were selected. According to whether DEACMP occurred within 60 days after discharge, the patients were divided into the DEACMP group ( n=33) and good prognosis group ( n=61). LCR and BIS of the two groups at different time points were compared, and the correlation between LCR and BIS was analyzed. The predictive value of LCR, BIS and the combination of the two for DEACMP was analyzed by receiver operating characteristic (ROC) curve. Results:The LCR and BIS of the DEACMP group at day 1t, 3 and 5 were significantly lower than those of the good prognosis group ( P<0.05). Pearson correlation analysis showed that there was a positive correlation between BIS and LCR in the DEACMP group at day 1, 3 and 5 ( r=0.371, P<0.05). There was also a positive correlation between LCR and BIS in the good prognosis group at day 1, 3 and 5 ( r=0.373, P<0.05). ROC curve analysis showed that the areas under the curves of LCR, BIS and the combination of the two for predicting the occurrence of DEACMP in patients with ASCOP were 0.803 (95% CI: 0.707~0.897), 0.941 (95% CI: 0.886~0.997), and 0.949 (95% CI: 0.879~1.000), respectively. Conclusions:LCR combined with BIS is of high predictive value for the occurrence of DEACMP in patients with ASCOP.

ABSTRACT

Objective:To investigate the effect of clinical factors on the short-term prognosis of patients with acute carbon monoxide toxic heart disease.Methods:From October 2017 to December 2019, 92 patients with acute carbon monoxide poisoning (ACOP) and toxic heart disease admitted to the Department of Emergency of our hospital were enrolled in this study. The duration from poisoning to hospital admission, duration of coma, length of hospital stay, endotracheal intubation or not, admission to ICU ward or not, acute physiology and chronic health evaluation (APACHEⅡscore) at admission were recorded. The heart rate-corrected QT dispersion (QTcd) calculated based on electrocardiography results, as well as levels of serum trocalin I (cTnI) and creatine kinase isoenzyme (CK-MB) were recorded at admission, day 2, day 3, and hospital discharge. According to the diagnostic criteria of occupational cute toxic cardiopathy caused by chemicals, the patients were divided into three groups: 45 cases in the mild heart disease group (mild group), 35 cases in the moderate heart disease group (moderate group) and 12 cases in the severe heart disease group (severe group). The variables data of each group were presented as Mean±SD, and analyzed using one-way anova test. LSD- t test was used for pairwise comparison between the groups. Attributes data were compared using χ 2 comparisontest, and correlations were analyzed using Spearman correlation method and binary logistic regression analysis. Results:APACHE II score was significantly higher, and the durations of coma, and hospitalization time of severe heart disease group were significantly higher longer in the severe heart disease group than those ofin the mild and moderate groups, and the proportions of patients with early tracheal intubation to protect airway and admission in ICU ward were both significantly lower in the severe heart disease group than those ofin the mild and moderate moderate groups (all P < 0.05). The levels of CTnI and QTcd in each group increased immediately after admission, which was statistically different from that in the normal control group ( P < 0.05), while cTnI and QTcd at admission in the severe group were significantly higher than those in the mild and moderateother two groups ( P < 0.05). The levels of CK-MB in the severe group wereas significantly different from thoseat of the mild to and moderate groups at day 2 and day 3 after admission ( P < 0.05). The correlation between serum cTnI and APACHE II score at admission was R1 = 1.000 and R2 = 0.458. The correlation between QTcd and APACHE II score at admission was R1 = 1.000 and R2 = 0.765. Both of them were positively correlationsed with statistical difference ( P < 0.01). Conclusions:Patients with ACOP should admit to hospital as early as possible. For patients with severe hypoxia and no airway protection ability, an artificial airway should be established as soon as possible, and the patients should admit to the ICU at the early stage of poisoning to stabilize their condition. Changes of QTcd, serum cTnI, CK-MB and other related indicators should be monitored to detect cardiac injury in time and protect heart.

ABSTRACT

Objective:To investigate the value of combined detection of neutrophil gelatinase-associated lipocalin(NGAL), cystatin C(CysC)and heme oxygenase-1(HO-1)in the early diagnostic of acute kidney injury(AKI)caused by acute paraquat poisoning(APP)in elderly patients.Methods:One hundred and two elderly APP patients admitted to the emergency department of our hospital from May 2015 to June 2019 were assigned to the observation group, and 50 patients who took physical examinations served as the control group.The observation group was divided into the AKI sub-group(n=59)and the non-AKI sub-group(n=43)based on whether AKI occurred within 72 h of admission.Serum levels of NGAL, CysC, HO-1 and creatinine(Scr)were detected in all APP patients at 0 h(admission), 12 h, 24 h, 48 h and 72 h. Measurements of the same parameters were made on the day of physical examination for the control group.The correlations of serum levels of NGAL, CysC and HO-1 with the occurrence of AKI were analyzed.Relative operating characteristic curve(ROC)was drawn to analyze the diagnostic value of NGAL, CysC, HO-1 and the combination of the three for the early diagnosis of renal injury in APP patients.Results:Serum levels of NGAL, CysC, HO-1 and Scr at admission showed no significant difference between the AKI sub-group, non-AKI sub-group and control group( P>0.05). After admission, all the parameters showed an upward trend in the observation group.Serum levels of NGAL, CysC and HO-1 at 12 h after admission( P<0.05)and Scr levels at 72 h after admission( P<0.05)were significantly different between the AKI sub-group and the non-AKI sub-group.Correlation analysis showed that serum NGAL, CysC and HO-1 levels were positively correlated with the occurrence of AKI in APP patients at 12 h, 24 h, 48 h and 72 h after admission, with the best correlation at 48 h after admission(NGAL: r=0.203, 0.545, 0.707 and 0.560, P<0.05; CysC: r=0.242, 0.340, 0.754 and 0.467, P<0.05; HO-1: r=0.249, 0.536, 0.677 and 0.509, P<0.05). The area under ROC curve predicted by NGAL, CysC, HO-1, Scr and NGAL+ CysC+ HO-1 for AKI at 48 h after admission was 0.777, 0.718, 0.888, 0.602 and 0.969, respectively. Conclusions:Serum levels of NGAL, CysC and HO-1 are significantly elevated at 12 h after admission in elderly APP patients, and reach the peak at 48 h after admission.Each of them can give an earlier diagnosis for AKI than Scr, and the combination of the three provides a higher diagnostic accuracy for AKI.
