The Correlation Between Serum Collagen III Levels and APRI in Liver Fibrotic HCV Patients

Abstract

Abstract Introduction/Objective Noninvasive Markers (NIM) of Liver Fibrosis help evaluate the stage of fibrosis in patients with no clear indication for a liver biopsy, such as patients with chronic hepatitis C who need monitoring of the stage of fibrosis during or after treatment. The perfect NIM for hepatic fibrosis should be inexpensive, safe, simple, reliable, and well-validated in different forms of chronic liver disease. Aim of the work Find if there is a correlation between serum collagen III and APRI as noninvasive markers in patients with HCV-induced liver fibrosis. Methods/Case Report 118 patients with HCV induced liver fibrosis (60 males and 58 females) and 50 healthy comparable control subjects (27 males and 23 females) were enrolled in the study. Collagen III was identified in serum samples of HCV-induced liver fibrosis patients at 70 kDa using collagen III polyclonal antibody and western blot analysis techniques. Collagen III was purified using the electroelution technique and then quantified using the ELISA technique. AST, ALT, albumin, and total bilirubin were measured. The APRI was calculated as [AST/ (upper limits of normal)/ platelets count 109/L]×100. The AST-ALT ratio was calculated as [AST/ ALT]. Results (if a Case Study enter NA) There was a statistically significant difference between the diseased and control groups (P<0.0001) regarding collagen III and APRI. Also, significant positive correlation between serum collagen III, APRI, and ALT levels (r=0.3 and p=0.02). However, there were no correlations between serum collagen III levels and AST, Albumin, Total Bilirubin, and AST/ALT ratio (r=0.15, -0.26, 0.22, and -0.027), respectively. Conclusion Collagen III and APRI is a promising diagnostic and prognostic potential in the noninvasive assessment of liver fibrosis as their levels elevate with each other. So, we can powerfully depend on them in liver fibrosis diagnosis in chronic HCV patients.
