Abstract
The present work was performed to evaluate the possibility to use testosterone, estradiol, zinc, copper andtheir ratios as a marker for liver insufficienty. Fifty-two positive HCV male patients with liver insufficiency were classified into 4 different groups: steatohepatitis (16), chronic hepatitis (17), cirrhosis (12) and HCC (7) besides, 24 healthy subjects served as control. Blood samples were withdrawn and imidiatly heamatological tests were made and the sera were obtained and liver functions tests, hormonal tesets (testosterone and estradiol) and trace elements determination were made (zinc and copper).The results of the present study showed a significant decrease (P<0.05 and P<0.001) in serum testosterone level and testosterone/estradiol ratio in patients with different liver states when compared with control. The serum testosterone level was significantly lower (P<0.05 and P<0.001)) in patients with cirrhosis than other patients group. On the other hand, there was a significant increase (P<0.01 and P<0.001) in serum estradiol level in all groups compared with control. Serum testosterone/estradiol ratio was less affected and significantly higher (P<0.01 and P<0.001) in patients with steatohepatitis than other patients group. Also, the results showed a significant decrease (P<0.001) in serum Zn level in patients when compared with control; a significant decrease (P<0.05) in cirrhosis compared with HCC. Also, a significant increase (P<0.01 and P<0.001) in serum Cu level and Cu/Zn ratio in different groups compared with control group. Serum Cu level significantly decreased in chronic hepatitis compared with cirrhosis and
