Urinary Cystatin C

Aim. To examine the assumption that significant concentrations of cystatin C in urine are the manifestation of the tubular necrosis and, respectively, the severity of kidney damage after heart transplantation (HTx).Materials and methods. In this study we evaluated 33 heart recipients (6 women and 27 men, aged from 24 to 68 years old) who had risk factors of acute kidney injury: serum creatinine level >113 μmol/l and/or mechanical circulatory support requirement (20 patients, in 14 cases before HTx). Cystatin C concentration in serum and in urine was measured by DyaSis particle-enhanced immunoturbidimetric assay test «Cystatin C FS».Results. Recipients were divided into two groups according to the levels of cystatinuria. In the group with the significant (more than 0.18 mg/l) urinary cystatin C concentrations the requirement of renal replacement therapy (RRT) was 2.5-fold higher, and the mean duration of RRT was more than 10-fold longer. In 2 patients with the significant cystatinuria acute kidney injury (AKI) has transformed into end-stage renal disease (ESRD).Conclusion. Due to data obtained we may suppose that significant concentrations of cystatin C in urine are the marker of the tubular necrosis with the prolonged RRT requirement. Further studies are needed to justify this relationship.

Urine Levels

Purpose. To assess urinary tissue inhibitor of metalloproteinases-2 and insulin-like growth factor binding protein 7 ([TIMP-2]·[IGFBP7]), urinary neutrophil gelatinase-associated lipocalin (NGAL), and urinary cystatin-C as acute kidney injury predictors (AKI) exploring the association of nonrenal factors with elevated biomarker levels.Methods. We studied 94 patients with urine collected within 48 hours of ICU admission and no AKI at sampling. AKI was defined by the Kidney Disease: Improving Global Outcomes criteria. Predictive performance was assessed by the area under the receiver operating characteristics (ROC) curve. Associations between biomarkers and clinical factors were assessed by multivariate linear regression.Results. Overall, 19 patients (20%) developed AKI within 48 hours. [TIMP-2]·[IGFBP7], NGAL, or cystatin-C admission levels did not differ between patients without AKI and patients developing AKI. [TIMP-2]·[IGFBP7], NGAL, and cystatin-C were poor AKI predictors (ROC areas 0.34–0.51). Diabetes was independently associated with higher [TIMP-2]·[IGFBP7] levels (P=0.02) but AKI was not (P=0.24). Sepsis was independently associated with higher NGAL (P<0.001) and cystatin-C (P=0.003) levels.Conclusions. Urinary [TIMP-2]·[IGFBP7], NGAL, and cystatin-C should be used cautiously as AKI predictors in general ICU patients since urine levels of these biomarkers are affected by factors other than AKI and their performance can be poor.
