Abstract

Abstract Background: Sepsis asscociated acute kidney injury (SA-AKI) is common condition that found in sepsis. Due to the lack of creatinine serum, this condition possibly makes therapy delayed. Kidney Injury Molecule-1 (KIM-1) is a a type 1 transmembrane protein with immunoglobulin and mucin domains, which is expressed increased in the proximal tubules of the kidney. Elevated urinary KIM-1 levels are an indicator of AKI. However, previous studies have shown varies results. Objectives: This study aims to determine early diagnosis biomarkers for the presence of AKI in sepsis. Methods: This diagnostic test was conducted at Dr. M. Djamil General Hospital Padang in sepsis patients. The diagnosis of AKI was established based on the 2012 KDIGO criteria. Results: The study involved 94 sepsis patients, only 22,34% (n=21) of them experienced AKI. Serum creatinine levels at admission and within 48 hours of hospitalization were 0,7 (IQR 0,2-1,6) mg/dl and 0,8 (IQR 0,3-2,2m) mg/dl. An urinary KIM-1 level at admission ≥11,74 ng/mL had sensitivity of 44,68%, specificity of 59,57%, positive predictive value of 52,5%, negative predictive value of 51,85%, and accuracy of 52,12% in early diagnosis of AKI in sepsis. Conclusion: Urinary Kidney injury molecule-1 level has poor diagnostic value in diagnosis of AKI in sepsis. Keywords: Sepsis, Kidney injury molecule-1, AKI.
