Abstract
OBJECTIVE: This research is aimed at investigating the relationship between liver fibrosis in viral hepatitis and macrophage colony-stimulating factor (M-CSF), tissue inhibitor of matrix metalloproteinase (TIMP-1), and ceruloplasmin (CER) in serum level. METHODS: Patients were randomly selected among those admitted to our hospital, and 60 healthy volunteers were chosen to serve as control participants. The levels of serum M-CSF, CER, and TIMP-1 were compared. According to the severity of their liver fibrosis, patients with CHB were separated into four groups: S1, S2, S3, and S4. Serum levels of M-CSF, CER, and TIMP-1 were correlated with liver fibrosis and hepatitis markers, and the diagnostic usefulness of the three indices was assessed with liver cirrhosis patients. RESULTS: Increases in M-CSF and TIMP-1 in the CHB group but decreases in CER were statistically significant (P < 0.05). Serum levels of M-CSF, CER, TIMP-1, HA, PC-III, C-IV, and LN differed significantly across the four study groups (P < 0.05). Over time, as liver fibrosis worsened, we observed a progressive uptick in M-CSF, TIMP-1, LN, HA, C-IV, and PC-III levels and a progressive downtick in CER levels, with significant (P < 0.05) differences between the groups. There was a significant positive correlation between liver fibrosis and serum M-CSF, PC-III, TIMP-1, HA, LN, and C-IV levels in the CHB group (P < 0.05) and a significant negative correlation between serum CER and these same factors (P < 0.05). The AUC of 0.956 for diagnosing the S4 stage was greater than that of 0.857, 0.851, and 0.817 for M-CSF, CER, and TIMP-1, respectively. CONCLUSIONS: In CHB patients, the liver fibrosis degree is associated with the M-CSF, CER, and TIMP-1 levels, and the combined clinical detection of these three markers has better diagnostic significance.
