Neutrophil Gelatinase

Snakebite-induced acute kidney injury (AKI) is frequently observed in patients following bites from vipers such as Russell’s viper (Daboia russelii) in India. Currently, the levels of serum creatinine are mainly used as a marker to determine the necessity for renal replacement therapy (RRT) (haemodialysis) in severe cases of AKI. However, it takes up to 48 h to ascertain a distinct change in creatinine levels compared to its baseline level upon admission. The time lost between admission and the 48 h timepoint significantly affects the clinical management of snakebite victims. Moreover, early diagnosis of AKI and decision on the necessity for RRT in snakebite victims is critical in saving lives, reducing long-term complications, and minimising treatment costs arising from expensive haemodialysis. Neutrophil gelatinase–associated lipocalin (NGAL) has been recently studied as a robust early marker for AKI in non-snakebite patients. However, its suitability for clinical use in snakebite victims has not been rigorously established. Here, we demonstrate the clinical significance of plasma NGAL as a robust marker for RRT following AKI using a large cohort (309) of Russell’s viper victims without any pre-existing health conditions. NGAL levels upon admission are positively correlated with creatinine levels at 48 h in different stages of AKI. Overall, NGAL acts as a robust early marker to ascertain the need for RRT following Russell’s viper bites. The quantification of NGAL can be recommended as a routine test in hospitals that treat snakebites to decide on RRT at early time points instead of waiting for 48 h to confirm the increase in creatinine levels. The diagnostic use of NGAL in Russell’s viper victims with pre-existing comorbidities and for other vipers should be evaluated in future studies.

Abstrak: Gagal ginjal akut (GGA) sering ditemukan dalam praktek klinik namun diagnosisnya dapat tertunda oleh karena keterbatasan alat diagnostik. Dewasa ini, kriteria diagnostik RIFLE, AKIN, dan KDIGO untuk menilai adanya GGA dan keparahannya dianggap tidak cukup untuk menggambarkan kompleksitas sindrom GGA. Proteinuria dan mikroalbuminuria yang merupa-kan marker klasik progresi cedera ginjal kronik, telah dipergunakan dan divalidasi untuk progresi GGA ke CKD. Kidney injury molecule-1 (KIM-1), neutrophil gelatinase-associated lipocalin (NGAL), dan urinary cystatin C dapat berperan dalam memrediksi pemulihan ginjal. Indikasi biopsi ginjal pada pasien kritis ialah gangguan ginjal yang tidak jelas atau progresi CKD dengan hematuria glomerulus dan proteinuria lebih dari 1 gram per hari, manifestasi ginjal dari penyakit sistemik yang mengancam nyawa, kecurigaan penolakan akut atau kronik dari ginjal transplan. Mempertahankan hemodinamik yang adekuat seharusnya bermanfaat dalam pence-gahan onset atau perburukan GGA, namun kelebihan cairan harus dihindari. Sampau saat ini penentuan saat inisiasi acute renal replacement therapy (ARRT) masih kontroversial, demikian pula nilai ambang spesifik untuk memulainya belum sepenuhnya disepakati.

Current practice suggests that RIFLE, AKIN, and KDIGO diagnostic criteria used to assess the presence of AKI and its severity are insufficient to illustrate the complexity of the AKI syndrome. Proteinuria and micro-albuminuria, classical markers of chronic kidney disease (CKD) progression, have been used and validated for the progression of AKI to CKD. Kidney injury molecule-1 (KIM-1), neutrophil gelatinase-associated lipocalin (NGAL), and urinary cystatin C could play a role in prediction of renal recovery. Indication of renal biopsy in critically ill patients are unexplained renal impairment or progression of CKD with both glomerular hematuria and proteinuria more than 1 gr per day, renal manifestations of life threathening systemic disease, suspected acute or chronic rejection of a transplanted kidney. The maintenance of adequate hemodynamics should be beneficial in preventing the onset or the worsening of AKI, but fluid overload should be avoided. Timing of acute renal replacement therapy (ARRT) initiation is still controversial, moreover, specific thresholds for starting are still unclear.Keywords: acute kidney injury (AKI); critically ill; glomerular filtration rate (GFR)

Background: To determine the optimal time for discontinuing continuous renal replacement therapy (CRRT) by evaluating serum neutrophil gelatinase-associated lipocalin (NGAL) in critically ill patients with acute kidney injury (AKI). Methods: A prospective observational study was conducted from September 2015 to March 2018. AKI patients treated with CRRT for at least 24 h were divided into “success” and “failure” groups according to their RRT requirement within 7 days after the initial discontinuation of CRRT. The prefilter and effluent NGAL concentrations were measured to calculate the sieving coefficient (SC) of NGAL in all included subjects from 0 to 72 h. Results: In total, 110 patients were divided into success (n = 78) and failure groups (n = 32). The mean SC of NGAL during CRRT was less than 0.05. The patients in the failure group were associated with higher mortality compared with patients in the success group (37.5 vs. 12.8%, respectively, p = 0.013). There were significant differences in serum NGAL, creatinine, and urine output at discontinuation. In patients without sepsis (n = 70), serum NGAL and urine output were significant predictors of successful cessation. The area under the receiver operating characteristic to predict the successful discontinuation of CRRT was 0.88 for NGAL and 0.86 for urine output. An NGAL level of 403 ng/mL had the highest sensitivity (81%) and specificity (89%) and a urine output of 695 mL/day had the highest sensitivity (83%) and specificity (88%). However, in septic patients (n = 40), urine output but not serum NGAL (OR 0.999, p = 0.69) was a significant variable (OR 1.002, p = 0.005), with a cutoff of 796 mL/day (sensitivity 83%, specificity 88%). Conclusions: Serum NGAL was a significant factor for predicting successful CRRT discontinuation in nonseptic AKI patients. However, urine output, rather than serum NGAL, was a significant predictor in septic AKI patients.
