Relationship between serum neutrophil gelatinase-associated lipocalin levels and cognitive impairment, anxiety, and depressive symptoms in acute ischemic stroke

BACKGROUND Acute ischemic stroke(AIS)is a significant global health issue with increasing incidence owing to aging populations and rising cardiovascular risk factors.In addition to physical impairments,AIS frequently leads to neuropsychiatric co-mplications,such as cognitive impairment,anxiety,and depressive symptoms,which adversely affect patients’quality of life and rehabilitation.Neutrophil ge-latinase-associated lipocalin(NGAL)has emerged as a potential biomarker for various conditions,including AIS.This study investigated the association bet-ween serum NGAL levels at admission and neuropsychiatric complications in patients with AIS.neuropsychiatric complications in patients with AIS.METHODS Between January 2022 and December 2023,150 patients with AIS were enrolled.Serum NGAL levels were measured at admission using an enzyme-linked immu-nosorbent assay.Cognitive function was assessed using the Mini-Mental State Examination,while anxiety and depressive symptoms were evaluated using the Hospital Anxiety and Depression Scale at discharge.The relationship between serum NGAL levels and cognitive impairment,anxiety,and depressive symptoms was analyzed using multivariate logistic regression,adjusted for potential con-founders of age,sex,body mass index,smoking status,hypertension,diabetes mellitus,dyslipidemia,previous stroke,and stroke severity.RESULTS The mean age of the participants was 65.4±10.2 years,and 58%were males.Prevalence rates of cognitive impairment,anxiety,and depressive symptoms at discharge were 34.7%,28.0%,and 32.0%,respectively.Serum NGAL levels were significantly higher in patients with cognitive impairment(median:5.6 ng/mL vs 3.2 ng/mL,P<0.001),anxiety(median:5.1 ng/mL vs 3.5 ng/mL,P=0.002),and depressive symptoms(median:5.4 ng/mL vs 3.3 ng/mL,P<0.001),compared to those without these conditions.Multivariate logistic regression analysis showed that higher serum NGAL levels at admission were independently associated with cognitive impairment[odds ratio(OR)=1.42,95%confidence interval(CI):1.18-1.71,P<0.001],anxiety(OR=1.28,95%CI:1.09-1.51,P=0.003),and depressive symptoms(OR=1.39,95%CI:1.16-1.67,P<0.001)after adjusting for potential confounders.CONCLUSION Elevated serum NGAL levels were independently associated with cognitive impairment,anxiety,and depressive symptoms in patients with AIS;and may function as potential biomarkers for patients at risk.

Reliability of neutrophil gelatinase-associated lipocalin in detecting acute tubular necrosis in decompensated cirrhosis:Systematic review and meta-analysis

BACKGROUND Acute kidney injury(AKI)in cirrhosis is common.The diagnosis of AKI in cirrhosis patients depends on clinical presentation and laboratory tests like serum creatinine.However,urine biomarkers could also be used to assess the type of AKI and the severity of the disease.We performed a systematic review with metaanalysis to evaluate the association with urine neutrophil gelatinase-associated lipocalin(NGAL)marker in identifying acute tubular necrosis(ATN)in patients with cirrhosis.AIM To assess the reliability of urine NGAL in the detection of ATN in patients with cirrhosis.METHODS We systematically searched MEDLINE and PubMed using keywords including“urine biomarkers”,“NGAL”,“kidney dysfunction”,and“cirrhosis”to identify relevant studies.Data was screened and extracted.Included studies assessed hospitalized cirrhosis patients with AKI using the urine NGAL biomarker.We synthesized the data using diagnostic odds ratio(DOR),comparative and descriptive analyses,and Cochran Mantel-Haenszel(CMH)statistics to evaluate heterogeneity.RESULTS Three thousand seven hundred and one patients with cirrhosis were analyzed from a total of 21 cohort studies.The DOR of 14 of those studies[pooled DOR:22.150,(95%CI:17.58-27.89),P<0.0001]demonstrated a significant association between urine NGAL levels and its identification of ATN.Following stratification by cirrhosis status,heterogeneity was analyzed and showed a significant non-zero correlation between NGAL and AKI(CMH statistic=702.19,P<0.0001).CONCLUSION In patients with cirrhosis,the use of urine NGAL is a reliable biomarker for detecting ATN and identifying the etiology of AKI.

Neutrophil gelatinase-associated lipocalin,kidney injury molecule-1,and periostin:Novel urinary biomarkers in diabetic nephropathy

BACKGROUND Globally,diabetic nephropathy(DN)is the primary cause of chronic kidney disease.Currently,renal function is monitored indirectly using measures of serum creatinine,estimated glomerular filtration rate(eGFR),and proteinuria.Novel urinary biomarkers utilized in the early stages of DN have been described;these indicators can be used in the early identification of the disease,which is important for initiating treatment to halt or impediment the advance of diabetic nephropathy.AIM To estimate neutrophil gelatinase-associated lipocalin(NGAL),kidney injury molecule-1(KIM-1),and periostin(POSTN)levels as novel urinary biomarkers in DN.METHODS In this hospital based cross-sectional study,a total of 160 patients of both genders aged 18 years or more;40 healthy participants and 120 patients with diabetes mellitus(DM)were included.Patients with DM were divided into normoalbuminuria(n=40),microalbuminuria(n=40),and macroalbuminuria(n=40)groups as per urine albumin creatinine ratio(uACR).Blood urea,serum creatinine,uACR were measured.Urine NGAL,KIM-1,and POSTN were measured by enzyme linked immunosorbent assay.The eGFR was calculated and compared with urinary markers.RESULTS NGAL,KIM-1,and POSTN levels increased significantly in normo,micro,and macroalbuminuria with the highest in the macroalbuminuria group.Albumin creatinine ratio(ACR)showed a positive correlation with NGAL,KIM-1,and POSTN levels.The eGFR showed a weak negative correlation with ACR,NGAL,KIM-1,and POSTN.NGAL was significantly lower in stage 1 compared to stage 2,3,and 4 kidney disease.KIM-1 was significantly decreased in stage 1 compared to stage 4 kidney disease.POSTN was significantly decreased in stage 1 compared to stage 3 and 4 kidney disease.The receiver operator curve analysis of ACR,NGAL,KIM-1,and POSTN showed good sensitivity of 80%,75.8%,63.3%,and 80%respectively with a cut-off of 12.5 mg/g,4.5μg/L,1.5 ng/mL,and 37.5 ng/mL.CONCLUSION Urinary NGAL and POSTN are independent markers of DN.

Serum Neutrophil Gelatinase-associated Lipocalin(NGAL)Is Elevated in Patients with Asthma and Airway Obstruction

Neutrophilic airway inflammation is one of the features of severe asthma.Neutrophil gelatinase-associated lipocalin(NGAL),or lipocalin-2,is a glycoprotein associated with neutrophilic inflammation and can be detected in blood.Recently,blood NGAL levels have been reported to be elevated in chronic obstructive pulmonary disease.However,the clinical significance of serum NGAL levels in patients with asthma has not been elucidated.The aim of this study was to explore the association between serum NGAL level and clinical parameters in patients with asthma.Sixty.one non-smoking people with stable asthma were enrolled in this study.All patients underwent blood ollction and pulmonary function tests.The associations between serum NGAL levels and clinical parameters were analyzed retrospectively.Serum NGAL levels in patients with asthma and obstructive ventilatory defect were higher than those in patients with asthma without obstructive ventilatory defect(76.4±51.4 ng/mL vs.39.3±27.4 ng/mL,P=0.0019).Serum NGAL levels were correlated with forced expired flow at 50%of vital capacity%predicted and forced expired flow at 75%of vital capacity%predicted(r=-0.3373,P=0.0078 and r=0.2900,P=0.0234,respectively).Results of a multiple regression analysis demonstrated that serum NGAL level was independently associated with obstructive ventilatory defect.Serum NGAL levels were elevated in patients with asthma and obstructive ventilatory defect.NGAL may be involved in airway remodeling possibly mediated by neutrophilic inflammation in asthma.

Neutrophil gelatinase-associated lipocalin does not predict acute kidney injury in heart failure

BACKGROUND Acute cardiorenal syndrome type 1(CRS-1)is defined by a rapid cardiac dysfunction leading to acute kidney injury(AKI).Neutrophil gelatinaseassociated lipocalin(NGAL)is expressed on the surface of human neutrophils and epithelial cells,such as renal tubule cells,and its serum(sNGAL)and urinary have been used to predict AKI in different clinical settings.AIM To characterize CRS-1 in a cohort of patients with acute heart diseases,evaluating the potentiality of sNGAL as an early marker of CRS-1.METHODS We performed a retrospective cohort,multi-centre study.From January 2010 to December 2011,we recruited 202 adult patients admitted to the coronary intensive care unit(CICU)with a diagnosis of acute heart failure or acute coronary syndrome.We monitored the renal function to evaluate CRS-1 development and measured sNGAL levels within 24 h and after 72 h of CICU admission.RESULTS Overall,enrolled patients were hemodynamically stable with a mean arterial pressure of 92(82-107)mmHg,55/202(27.2%)of the patients developed CRS-1,but none of them required dialysis.Neither the NGAL delta value(AUC 0.40,95%CI:0.25-0.55)nor the NGAL peak(AUC 0.45,95%CI:0.36-0.54)or NGAL cutoff(≥140 ng/mL)values were statistically significant between the two groups(CRS-1 vs no-CRS1 patients).The area under the ROC curve for the prediction of CRS-1 was 0.40(95%CI:0.25-0.55)for the delta NGAL value and 0.45(95%CI:0.36-0.54)for the NGAL peak value.Finally,in multivariate analysis,the risk of developing CRS-1 was correlated with age>60 years,urea nitrogen at admission and 24 h-urine output(AUC 0.83,SE=60.5%SP=93%),while sNGAL was not significantly correlated.CONCLUSION In our population,sNGAL does not predict CRS-1,probably as a consequence of the mild renal injury and the low severity of heart disease.So,these data might suggest that patient selection should be taken into account when considering the utility of NGAL measurement as a biomarker of kidney damage.

Combination of neutrophil gelatinase-associated lipocalin and matrix metalloproteinase-9 are biomarkers for the detection of colon tubular adenocarcinoma

BACKGROUND Tubular adenocarcinoma of the colon,which originates from the epithelium of the glands,is a major health concern worldwide.However,it is difficult to detect at an early stage.The lack of biomarkers is a main barrier to the diagnosis and treatment of tubular adenocarcinoma.Neutrophil gelatinase-associated lipocalin(NGAL)is a secreted protein that induces the expression of matrix metalloproteinase-9(MMP-9)and is involved in various tumors.NGAL and MMP-9 have been reported to be associated with tumorigenesis and development.They may have potential as biomarkers for diagnosis of tubular adenocarcinoma of the colon.AIM To determine whether NGAL and MMP-9 can be used as potential biomarkers to indicate the progression of tubular adenocarcinoma of the colon.METHODS Samples were collected from surgically excised tissue from various patients.The content of pro-gastrin-releasing peptide(pro-GRP)in the serum was measured by an electrochemiluminescence immunoassay.The expression patterns of NGAL and MMP-9 and the relationship between NGAL and MMP-9 were examined by quantitative real-time PCR,Western blotting and immunohistochemical analysis.RESULTS In this study,we found that NGAL and MMP-9 can be used as biomarkers for the detection of tubular adenocarcinoma of the colon and that their combination improved diagnostic accuracy.By analyzing the expression of NGAL in tubular adenocarcinoma at different levels,we found that NGAL expression was significantly upregulated in primary tubular adenocarcinoma tissues compared with normal tissues.The upregulation of NGAL expression was strongly correlated with both the degree of differentiation and the disease stage(I–III),indicating that NGAL could serve as a diagnostic biomarker for tubular adenocarcinoma.When using NGAL as a biomarker for diagnosis,the accuracy was similar to that achieved with the widely used biomarker pro-GRP,suggesting that NGAL is reliable.Moreover,the expression of MMP-9 was also strongly correlated with the differentiation stage,demonstrating that MMP-9 could be used as a biomarker to indicate the progression of tubular adenocarcinoma of the colon.More importantly,the combination of NGAL and MMP-9 produced a more accurate diagnosis of tubular adenocarcinoma,and these results were further confirmed by immunohistochemical analysis of tissue sections.CONCLUSION Our study demonstrated that both NGAL and MMP-9 can be used as biomarkers for the diagnosis of colon tubular adenocarcinoma and that the results could be further improved by combining them.

The Differences of Urinary Neutrophil Gelatinase-Associated Lipocalin (NGAL) Levels between Asphyxiated and Non-Asphyxiated Neonates

Objective: To evaluate the differences of urinary NGAL levels between asphyxiated and non-as- phyxiated neonates. Methods: This was a cross-sectional observational analytic study, including 34 newborns in Dr. Hasan Sadikin Hospital, Bandung, Indonesia. Sample collection was conducted from December 2014 to March 2015. Urine NGAL levels were evaluated using enzyme-linked immunosorbent assays (ELISA) technique. To determine the differences of urinary NGAL levels between asphyxiated and non-asphyxiated group we used Mann-Whitney U test, and to determine the differences of gestational age and birth weight between these two groups we used Fisher’s exact test. Results: Twenty males (60%) and 14 females (40%) neonates participated in the study. From 34 subjects, 17 neonates were diagnosed with asphyxia and 17 neonates without asphyxia. The results showed that urine NGAL levels had significantly increased in asphyxiated neonates. The median urine NGAL level in asphyxiated group is 95% CI: 506.7 (60.0 - 651.7) ng/mL, while the median urine NGAL level in non-asphyxiated group is 95% CI: 6.7 (0.1 - 53.0) ng/mL. Statistically, there were significant urine NGAL levels differences between asphyxiated and non-asphyxi- ated neonates (p < 0.001). There were no differences in gestational age and birth weight between asphyxiated and non-asphyxiated neonates (p > 0.05). Conclusions: Urinary NGAL levels in asphyxiated neonates were significantly higher than those in non-asphyxiated neonates. There were significant differences of urine NGAL levels between the groups.

Evaluation of Reticulocyte Hemoglobin Content and Serum Neutrophil Gelatinase-Associated Lipocalin as Predictive Biomarkers of Anemia in Children on Hemodialysis

Background: Diagnosis of iron deficiency anemia with currently available tests is rendered difficult in hemodialysis patients. The aim: To investigate the role of reticulocyte Hemoglobin Content (CHr) in the diagnosis of iron deficiency anemia in hemodialysis children in comparison to the used traditional markers and assess the impressiveness and the utility of Neutrophil Gelatinase Associated Lipocalin (NGAL) as a novel biomarker of iron status in those patients. Methods: This study investigated CHr in addition to NGAL serum level in the same line with traditional markers for anemia, including: CBC, serum iron, ferritin, total iron-binding capacity (TIBC), and transferrin saturation (TSAT%). Results: It is more significant that CHr content in hemodialysis children is lower than their controls as they are (27.06 ± 2.90) pg and (32.86 ± 3.59) pg, respectively, p = 0.01. There is no significant difference regarding NGAL between the study groups. Significant negative correlation between CHr with ferritin, urea, creatinine, and positively correlated with iron and RBCS. CHr showed a sensitivity of 90% and specificity of 86.67% to detect iron-deficiency anemia with a cut-off value of 27 pg. Conclusion: CHr is superior to ferritin and TSAT % for the early diagnosis of iron deficiency anemia in hemodialysis children;our results do not support NGAL as a marker of anemia in hemodialysis patients.
