Abstract :

Background & Aim: Cardiac surgery-associated acute kidney injury (CSA-AKI) is a highly progressive problem characterized by long-term ICU with devastating renal dysfunction over time resulting in a permanent renal tubular damage and/ or high susceptibility for deaths after days of the surgery. However, CSA-AKI is a multifactorial, but remains the effect of cardiopulmonary bypass (CPB) used during surgery with the prominent one. In this study, we assessed NGAL and Cystatin C in serum levels with routine serum creatinine to evaluate whether there are any reliable markers for AKI in the earlier timings. Methods: Fifty (50) patients were classified according to KDIGO criteria into AKI (n=26) and non-AKI (n=24) groups where, serum creatinine, NGAL and Cystatin C levels were quantified in the preoperative, perioperative and within 2 days of the surgery. Results: Preoperative levels of Serum NGAL were increased in the AKI group (100±39.2) than non-AKI group (78.6±45.5), reaches the uttermost values at 0 h in both groups with significant distinct proportions but, suddenly reduced from 2 h to 2 days of CPB with (p?0.05). Further, serum Cystatin C levels exhibited a significant increasingly behavior (p?0.001) in AKI vs. non-AKI starting with baseline (856±400 vs. 747±276), at 0 h (932±480 vs. 724±177), at 2 h (949±557 vs. 700±170) and persisted high until 48 h of CPB (1421±739 vs. 910±422) respectively. Conclusion: Despite controversial results of serum NGAL, Cystatin C levels showed a highly discriminative power against CSA-AKI in the earlier 2 h of CPB. Therefore, studies on large scale are recommended to reveal which comorbidities affected serum NGAL levels.
