Abstract

Objective: Almost half of intensive care patients are affected by acute kidney injury (AKI). The purpose of this study is to determine parameters that can be used for predicting of early (within 28 days) and late (within 90 days) mortality in patients who are followed-up with AKI in intensive care units. Materials and Methods: In this study, a dataset that contains 50 patients with AKI in intensive care units was used. This dataset contains blood urea nitrogen, creatinine, plasma and urinary neutrophil gelatinase-associated lipocalin (NGAL), lactate dehydrogenase, alkaline phosphatase and gammaglutamyl transpeptidase values of patients who were admitted to intensive care for various reasons and who developed AKI on the days 1, 3 and 7. In addition to these values, laboratory results such as serum electrolytes on day 1, blood gas; vital signs such as mean arterial pressure, central venous pressure; and demographic data were also recorded. Data mining techniques were applied to determine correlation between all of these data and mortality. Results: The threshold level of urinary NGAL on day 7 was determined to be 69 ng/mL, and strong correlation was found between this threshold level and early mortality. Similarly, the threshold level of plasma NGAL on day 7 was determined to be 150 ng/mL, and this was highly correlated with early mortality. Besides, strong correlation was also found between the difference in the urinary NGAL levels on day 1 and 7, and early mortality. Conclusion: In this study, plasma and urinary NGAL levels were found to be closely related to early mortality in patients who were followed-up with AKI in intensive care units. On the other hand, any parameter associated with late mortality was not found.

Özet

Amaç: Yoğun bakım hastalarının yarıya yakını akut böbrek hasarından (ABH) etkilenmektedir. Bu çalışmanın amacı; yoğun bakımda ABH ile takip edilen hastaların, erken (28 gün içinde) ve geç (90 gün içinde) mortalite tahmininde kullanılabilecek parametreleri tespit etmektir. Gereç ve Yöntem: Bu çalışmada, yoğun bakımda 50 hasta ile yapılan bir çalışmanın veri seti kullanıldı. Bu veri seti; çeşitli nedenlerle yoğun bakıma alınan ve ABH gelişen hastaların 1., 3. ve 7. günlerdeki; kan üre azotu, kreatinin, plazma ve idrar nötrofil jelatinaz ilişkili lipokalin (NGAL), laktat dehidrogenaz, alkalen fosfataz ve gama-glutamil transpeptitaz değerlerini içermektedir. Bu değerlere ek olarak, 1. gündeki serum elektrolitleri, kan gazı gibi laboratuvar sonuçları; ortalama arter basıncı, santral venöz basıncı gibi vital bulgular ve demografik veriler de bulunmaktadır. Bu veriler ile mortalite arasındaki korelasyonun tespiti için, veri madenciliği teknikleri kullanıldı. Bulgular: İdrar NGAL’nin 7. gündeki seviyesi için eşik değer 69 ng/mL olarak tespit edilmiş olup, bu eşik seviye ile erken mortalite arasında güçlü korelasyon bulunmuştur. Benzer şekilde, plazma NGAL’nin 7. gündeki seviyesi için eşik değer 150 ng/mL olarak tespit edilmiş olup, bu eşik seviye erken mortalite ile yüksek korelasyon göstermiştir. Ayrıca idrar NGAL’nin 1. ve 7. gündeki seviyeleri arasındaki fark ile erken mortalite arasında da güçlü korelasyon bulunmuştur. Sonuç: Bu çalışmada; yoğun bakımda ABH ile takip edilen hastaların, plazma ve idrar NGAL seviyelerinin erken mortalite ile yakından ilişkili olduğu görülmüştür. Diğer yandan, geç mortalite ile ilişkili herhangi bir parametre ise bulunamamıştır
