It is assumed that serum concentrations of type I, III, IV collagen (Col I, Col III, Col IV) and hyaluronic acid (HA) can provide informative evidence for the diagnosis of liver fibrosis (LF) using non-invasive procedures, however, there is insufficient data on the subject in paediatrics. Objectives: to study characteristics of changes in concentrations of Col I, Col III, Col IV and HA in blood serum in accordance with the stages of liver fibrosis in children. Materials and methods of research: a prospective study was carried out, which included 80 patients aged 5 to 17 years with chronic liver diseases of various etiologies, who underwent marginal resection of liver tissue under laparoscopic control, then a morphological study of the obtained biopsy was performed with determination of the stage of fibrosis on the METAVIR scale and the content of Col I, Col III, Col IV and HA in blood serum by the method of enzyme immunoassay. Results: the assessment of the content of K-I in the blood serum allows differentiating the stage F1 and F3 from F4 (p=0,025, p=0,006), Col IV – F1 from F2 (p=0,011), F3 (p=0,002) and F4 (p<0,001), HA – F1 from F3 (p=0,041), and also F4 from F1 (p<0,001), F2 (p<0,001) and F3 (p<0,001). There were no statistically significant differences in the content of Col III at different stages of LF (p=0,061). Statistically significant correlations of the histological stage of LF with changes in serological levels of Col I (ρ=–0,267, p=0,023), Col IV (ρ=0,409, p<0,001), and HA (ρ=0,575, p<0,001), and also the relationship between the concentrations of Col IV and HA (ρ=0,265, p=0,023). Conclusions: the correlations found in the histological phase of LF with changes in serological levels of Col I, Col IV and HA lead to the conclusion that fibrosis direct biomarkers are of diagnostic importance in determining the stage of LF, which is of great importance for practical medicine, especially in pediatrics.

Abstract Background Liver biopsy is the gold standard for detecting the degree of liver fibrosis; however, invasiveness constitutes its main limiting factor in clinical application, so we aimed to evaluate the non-invasive biomarker formulas (APRI and FIB-4) and their modified forms by BMI z-score (M-APRI, M-FIB-4, and B-AST) compared to liver biopsy in the assessment of liver fibrosis in children with chronic liver diseases. Two hundred children aged 6.3 ± 3.8 years (98 males, 102 females) with chronic liver diseases underwent liver biopsy. The stage of fibrosis was assessed according to the METAVIR system for all children, and the following non-invasive biomarker formulas were calculated: APRI, modified APRI (M-APRI: BMI z-score × APRI), Fibrosis-4 index (FIB-4), modified FIB-4 (M-FIB-4: BMI z-score × FIB-4), and B-AST (BMI z-score × AST). The best cutoff value was calculated to detect early fibrosis (F1–F2) from advanced liver fibrosis (F3–F4). Results There were positive correlations between all studied non-invasive biomarker models (APRI, FIB-4, M-APRI, M-FIB-4, B-AST) and fibrosis score as an increase in fibrosis score was associated with an increase in mean ± SD of all studied biomarker formulas. The best cutoff values of non-invasive biomarker models in the diagnosis of early fibrosis (F1–F2) were APRI > 0.96, M-APRI > 0.16, FIB-4 > 0.019, M-FIB-4 > 0.005, and B-AST > −8 with an area under the curve above 0.7 each, while the best cutoff values of non-invasive biomarker models (APRI, M-APRI, FIB-4, M-FIB-4, and B-AST) in the diagnosis of advanced liver fibrosis (F3–F4) were >1.96, >2.2, >0.045, and >0.015, >92.1, respectively, with an area under the curve above 0.8 each. Conclusion APRI, M-APRI, FIB-4, M-FIB-4, and B-AST are good non-invasive alternatives to liver biopsy in the detection of liver fibrosis in children with chronic liver diseases of different etiologies especially those that include BMI z-scores in their formulas.

Non-invasive techniques for liver fibrosis assessment were developed for adults and recent researches tested their accuracy in children. The only validated elastographic method for non-invasive liver fibrosis evaluation in children is Transient Elastography (TE). The aim of our study was to investigate the feasibility of liver stiffness (LS) measurement in paediatric patients with chronic liver diseases by means of Acoustic Radiation Force Impulse Elastography (ARFI) and 2D-Shear Wave Elastography (2D-SWE), compared to TE as reference method. Material and methods: We enrolled 54 consecutive children and adolescents with different chronic liver diseases. All patients were examined by means of TE, ARFI, and 2D-SWE. All measurements were performed in the right liver lobe, in the same session, in fasting condition. We considered reliable LS elastographic measurements as follows: for TE and ARFI - the median value of ten measurements with a success rate≥60% and an interquartile range<30%, for 2D-SWE - the median value of five measurements. Results: The successful measurement rate for TE was 94.4% (51/54). Taking TE as a reference method, sensitivity of ARFI for detecting fibrosis F1 was 71.42%, for F2-77.77%, for F3-62.5% and for F4-71.42%. Sensitivity of 2D-SWE for detecting F1 was 92.85%, for F2-83.33%, for F3-87.5% and for F4-85.71%. We found  significant correlations between TE and 2D-SWE on the entire lot (Kappa correlation factor=0.843, p=0.001). Analyzing the subgroup with SR=60%-70%, we did not find significant correlation between TE and ARFI (Kappa correlation factor=0.172, p=0.452). Assessing the subgroup with SR>70%, we found a significant correlation between TE and ARFI (Kappa correlation factor=0.761, p=0.001). Conclusions: Overall, 2D-SWE correlate better with TE compared to ARFI in children. Excluding patients with less satisfactory technical parameters, we obtained significant correlations between all three methods. Both SWE and ARFI are non-invasive techniques feasible of performing  on paediatric patients along with TE.
