Abstract
The aim of the study was to assess the role of hepatocellular death and systemic inflammation in the development of acute kidney injury (AKI) in acute decompensation of alcoholic liver cirrhosis (AD ALC).Materials and methods. 125 patients with ALC were examined: 20 (16.0%) (group I) with signs of hepatorenal syndromeacute kidney injury (HRS-AKI) at the age of 57.13 ± 9,08 years, 13 men (65.0%) and 105 (84.0%) patients (group II) without such a syndrome at the age of 56.30 ± 9.6 years., 62 men (59.0%). Along with liver tests, a markers of hepatocyte apoptosis and cytokines were determined by ELISA: fragments of cytokeratin-18 (FCK-18) ("Biotech" Sweden), cytokines — TNF-α, IL-1β, IL-4, IL-6, IL-8 (“Vector-Best”, Russia). Grade and index of acute on chronic liver failure (ACLF) were determined using an on-line calculator (www.efclif.com/scientific-activity/score-calculators/clif-c-aclf).Results. The hepatocellular death indicators were significantly higher in patients of group I with HRS-AKI compared with patients of group II without HRS-AKI: FCK-18-1609.44 ± 542.79 U / l versus 975.77±607.59 U / l, bilirubin — 242.64 ± 98.14 pmol/l versus 145.09 ± 79.35 pmol/l, inflammation indicators — TNF-α — 9.28 ± 3,11 pg/ml versus 6.59 ± 2.21 pg/ml, IL-6-54.79 ± 17.7 pg/ml versus 36.71 ± 18.05 pg/ml, CRP — 49.68 ± 23.23 mg/l versus 22.07 ± 20.40 mg/l, leukocytes — 12.23 ± 3.28x109/l versus 8,66 ± 2,31x109/l (everywhere p <0.05). ACLF developed in all (100.0%) patients of group I, its grade was 2.73±0.76 and score — 56.33 ± 4.01; ACLF developed only in 37 (35,2%) patients of group II, its grade was1.05±0.24 (p<0,05) and score was 47.45 ± 4,80 (p <0.05).Conclusion. The development of HRS-AKI in patients with acute decompensation of ALC was associated with significantly higher rates of hepatocytic apoptosis, hyperbilirubinemia, systemic inflammation, frequency and severity of ACLF.
