02; 95% CI 1.50–12.0; P = 0.0051). As compared with the group without early AKI, the urinary L-FABP level in early AKI group was significantly higher not only on the day of SCT

but also at the baseline. Then, ROC analysis demonstrated the urinary L-FABP level at baseline had good discriminative ability for the early AKI. Conclusion: One-quarter of allogeneic PI3K inhibitor SCT recipients developed the early AKI, which was linked with increased risk of their short-term mortality. Antecedent kidney damage, which can be identified by urinary L-FABP concentration, may portend the emergence of early-onset AKI.

Methods: This study enrolled 98 patients who were admitted to the adult mixed ICU of The University of Tokyo Hospital from July 2011 to October 2011 by consecutive sampling. Urine TIMP-2 and NAG, and plasma NGAL and IL-6 were measured

on ICU admission. This MAPK inhibitor study was aimed to evaluate whether these biomarkers

could predict AKI and its severity, and mortality by ROC analysis. Results: AKI occurred in 42 (42.9%) patients including 27 (27.6%) severe AKI (KDIGO stage 2 or 3). The area under the ROC curve for each marker was shown in Table. Forty one (41.8%) patients was complicated with sepsis, including 19 (19.4%) severe AKI. In accordance with previous reports, plasma NGAL and IL-6 were increased by sepsis, however urine TIMP-2 and NAG was increased not by sepsis but by the presence of severe AKI (Figure). In-hospital mortality was 15.3% in this cohort and urine TIMP-2 and NAG, and plasma NGAL were significantly higher in the non-survivors than the survivors, whereas plasma IL-6 was not significantly associated with mortality. Conclusion: A new urine biomarker of TIMP-2 is increased especially in severe AKI and associated with mortality. Sepsis appeared to have a smaller impact on urine TIMP-2 and NAG compared with plasma NGAL and IL-6. This distinct feature of biomarkers will enable to evaluate the contribution of sepsis to the development of AKI.
