Abstract
- BACKGROUND/AIMS
To investigate the degree of cyclooxygenase-2 (COX-2) protein expression in chronic hepatitis and cirrhosis.
METHODS
COX-2 protein expression was evaluated in 43 cases of chronic hepatitis and 24 cases of cirrhosis using immunohistochemical techniques. The COX-2 immunohistochemical staining score was assessed using the scoring systems of Pazirandeh et al and Qiu et al. and each scoring system was based on a sum of the parameters of staining intensity and distribution.
RESULTS
The mean COX-2 expression scores in chronic hepatitis and cirrhosis were 2.5 +/- 1.3 vs. 3.3 +/- 1.1 (p = 0.008), and 3.2 +/- 2.0 vs. 4.5 +/- 1.7 (p = 0.006), respectively, based on the Pazirandeh et al. and Qiu et al. scoring systems. The percentage samples of high COX-2 expression score (4 to 5) in chronic hepatitis and cirrhosis were 16.3% vs. 45.8% (p = 0.022), and 23.3% vs. 50% (p = 0.021), respectively, based on the two scoring systems. The mean COX-2 expression scores based on the severity of hepatic fibrosis scored using Ishak's modified staging system (fibrosis score 0 to 3 vs. 4 to 6) were 2.4 +/- 1.3 vs. 3.2 +/- 1.1 (p = 0.009), and 3.1 +/- 2.0 vs. 4.3 +/- 1.8 (p = 0.009), respectively, based on the two scoring systems.
CONCLUSIONS
COX-2 expression was significantly higher in liver cirrhosis group than in chronic hepatitis. COX-2 expression scores according to Ishak's staging was significantly higher in the advanced fibrosis group. COX-2 may play a role in the progression of hepatic fibrosis.
