In this study, we evaluated the diagnostic and prognostic value of the neutrophil gelatinase-associated lipocalin-2 (NGAL) level in urine as an early marker of renal dysfunction in preterm infants with very low and extremely low body weight. Aim - evaluation of diagnostic and prognostic significance of the urinary NGAL level as an early biomarker of acute kidney injury (AKI) in preterm infants. Materials and methods. The study included 104 premature babies, 78 of which formed the main group (AKI), and 26 babies - the comparison group (non-AKI). The main criterion for acute kidney injury in neonates according to neonatal classification AKIN (2011) is creatinine level > 1.5 mg/dL at the age of not earlier than 48 hours after birth. Results. The study identified a statistically significant correlation in the level of NGAL in the urine of children from the main and comparison groups. Conclusion. Biomarkers of kidney damage can give more accurate information than creatinine for the early diagnosis of AKI in children. In a comprehensive assessment of a child, it is necessary to take note of the indicators of renal function (creatinine, GFR) and biomarkers of injury (NGAL). This approach will allow performing the diagnostics and therapy of early AKI in children based on structural and functional criteria.

Aim: To assess and compare the roles of plasma and urine concentrations of neutrophil gelatinase associated lipocalin (NGAL) and Cystatin C for early diagnosis of septic acute kidney injury (AKI) in adult critically ill patients.Methods: Patients were divided into three groups as sepsis-non AKI, sepsis-AKI and non sepsis-non AKI. Plasma samples for NGAL and Cystatin C were determined on admission and on alternate days and urinary samples were collected for every day until ICU discharge.Results: One hundred fifty one patients were studied; 66 in sepsis-non AKI, 63 in sepsis-AKI, 22 in non-sepsis-non-AKI groups. Although plasma NGAL performed less well (AUC 0.44), urinary NGAL showed significant discrimination for AKI diagnosis (AUC 0.80) with a threshold value of 29.5 ng/ml (88% sensitivity, 73% specificity). Both plasma and urine Cystatin C worked well for the diagnosis of AKI (AUC 0.82 and 0.86, thresholds 1.5 and 0.106 mg/L respectively).Conclusion: Plasma and urinary Cystatin C and urinary NGAL are useful markers in predicting AKI in septic critically ill patients. Plasma NGAL raises in patients with sepsis in the absence of AKI and should be used with caution as a marker of AKI in septic ICU patients.

BACKGROUND: Acute kidney injury (AKI) is a complication found in critically ill patients. Current consensus explains that diagnosis of AKI based on increased serum creatinine and decreased urine output. Neutrophil gelatinase-associated lipocalin (NGAL) level is increased a few hours after tubular damage occurred and can predict AKI more significantly than serum creatinine. Renal resistive index (RRI) is also a good marker in predicting the early stage of AKI. AIM: This study aimed to compare RRI and NGAL level as marker to predict incidence of AKI in critically ill patients treated in the Intensive Care Unit (ICU) at H. Adam Malik Hospital Medan. METHODS: This was an observational prospective cohort study and conducted in ICU at H. Adam Malik Hospital Medan in April-May 2021. This study had been approved by the Ethics Committee of Faculty of Medicine, Sumatera Utara University and H. Adam Malik Hospital Medan. Inclusion criteria are critical patients aged 18–65 years with 1st and 2nd priority level. Consecutive sampling was used. Resistive Index (RI) measured using USG Doppler by researcher and the results confirmed by ICU supervisors, while urine NGAL level measured within 3 h after ICU admission. Plasma urea and creatinine level measured after 24h after ICU admission. RESULTS: A total of 40 samples were collected; percentage of men and women are 66–35%, respectively (p = 0.001). There was a significant difference RI between AKI-group and non-AKI group (0.719 ± 0.060 and 0.060 ± 0.077, respectively) (p = 0.001). RI has a sensitivity of 71%, specificity of 84%, and accuracy of 87% in predicting occurrence of AKI with AUROC = 0.873. Meanwhile, NGAL has a sensitivity, specificity, and accuracy (66%, 89%, 78%, respectively) in early prediction of AKI incidence in critically ill patients. CONCLUSION: RI value was higher in AKI group than non-AKI group. RRI has better sensitivity than NGAL in predicting incidence of AKI.

Diagnostic Usefulness

Acute pancreatitis (AP) belongs to the commonest acute gastrointestinal conditions requiring hospitalization. Acute kidney injury (AKI) often complicates moderately severe and severe AP, leading to increased mortality. Among the laboratory markers proposed for early diagnosis of AKI, few have been studied in AP, including cystatin C and neutrophil gelatinase-associated lipocalin (NGAL). Beta-trace protein (BTP), a low-molecular-weight glycoprotein proposed as an early marker of decreased glomerular filtration, has never been studied in AP. We investigated the diagnostic usefulness of serum BTP for early diagnosis of AKI complicating AP in comparison to previously studied markers. BTP was measured in serum samples collected over the first three days of hospital stay from 73 adult patients admitted within 24 h of mild to severe AP. Thirteen patients (18%) developed AKI in the early phase of AP. Serum BTP was higher in patients who developed AKI, starting from the first day of hospitalization. Strong correlations were observed between BTP and serum cystatin C but not serum or urine NGAL. On admission, BTP positively correlated with endothelial dysfunction. The diagnostic usefulness of BTP for AKI was similar to cystatin C and lower than NGAL. Increased BTP is an early predictor of AKI complicating AP. However, it does not outperform cystatin C or NGAL.

To investigate the predictive effects of neutrophil gelatinase-associated lipocalin (NGAL) and kidney injury molecule-1 (KIM-1) on renal-replacement therapy for traumatic acute kidney injury (TAKI). The urinary NGAL and KIM-1 levels of TAKI patients underwent renal-replacement therapy were assessed. The correlation and predictive model were also analyzed. Short-term (28 days) survival rate of patients were 54.5%. As TAKI stage increased, urinary KIM-1 and NGAL level increased significantly ( P < 0.05). The urinary KIM-1 and NGAL level, negatively correlated with 28-day survial, were all higher in deceased patients than survival patients ( P < 0.05). The Youden index demonstrated the predictive value of urinary NGAL area under the curve (AUC; 0.830) and KIM-1 AUC (0.879) levels in the prognosis of patients in this study. NGAL and KIM-1 can predict the prognosis of patients with TAKI and have significant correlation with the prognosis of patients.
