Abstract

Background: Patients with hepatorenal syndrome carry a high short-term mortality. Early diagnosis and treatment are essential for patients’ outcome. Nevertheless diagnosis of HRS remains difficult. First-line therapy terlipressin is often associated with severe complications. Biomarkers become more on focus for an early diagnosis.Objective: The aim of this study was to test the diagnostic accuracy of urinary [TIMP-2]·[IGFBP7] for HRS patients and prognostic value for therapy responding patients.Material and methods: NephroCheck® measures urinary concentrations of TIMP-2 and IGFBP-7, both indicating stress of renal cells and associated with induction of cell cycle arrest. 22 HRS patients and 30 patients with normal kidney function were included. [TIMP-2]·[IGFBP7] was measured using NephroCheck®. HRS patients receiving terlipressin were also examined.Results: [TIMP-2]·[IGFBP7] values did not differ significantly (1.3 ± 2.09 vs. 1.03 ± 1.03; p = 0.55). Furthermore, there was no significant difference of [TIMP-2]·[IGFBP7] regarding response of terlipressin (1.32 ± 2.39 vs. 0.81 ± 1.05; p = 0.56). Low [TIMP-2]·[IGFBP7] values were significantly associated with higher mortality (p = 0.01).Conclusions: The results of this study suggest that [TIMP-2]·[IGFBP7] is not suitable for diagnostic of HRS and prediction of therapy response, but there might be evidence for prognostic value of [TIMP-2]·[IGFBP7] in regard to mortality of liver cirrhosis patients.
