Background and Aim. The best staining to evaluate liver fibrosis in liver
hepatitis is still a debated topic. This study aimed to compare Masson's
trichrome (MT), Sirius Red (SR), and orcein stainings in evaluating liver
fibrosis in chronic HCV hepatitis (CHC) with semiquantitative and quantitative
methods (Collagen Proportionate Area (CPA) by Digital Image Analysis (DIA)) and
correlate them with transient elastography (TE). Methods. Liver stiffness
evaluation of 111 consecutive patients with CHC was performed by TE.
Semiquantitative staging by Metavir score system and CPA by DIA were assessed on
liver biopsy stained with MT, SR, and orcein. Results. MT, SR, and orcein
staining showed concordant results in 89.6% of cases in staging CHC, without
significant difference in both semiquantitative and quantitative evaluations of
fibrosis. TE values were concordant with orcein levels in 86.5% of the cases and
with MT/RS in 77.5% (P < 0.001). No significant correlation between the grade of
necroinflammatory activity and TE values was found. Conclusion. In CHC, SR/MT and
orcein stainings are almost concordant and when discordant, orcein staining is
better related to TE values than MT/RS. This suggests that elastic fibers play a
more important role than reticular or collagenous ones in determining stiffness
values in CHC.
