Pentraxin-3 and nitric oxide as indicators of disease severity in alcoholic cirrhosis.

Recent studies have indicated that pentraxin-3 can be used as a marker to assess the severity of hepatic fibrosis in non-alcoholic steatohepatitis. The present study was designed to assess pentraxin-3, nitric oxide and tumour necrosis factor-α (TNFα) in alcoholic cirrhosis and their association with disease severity. We enrolled 47 alcoholic cirrhosis cases and 32 controls. Serum pentraxin-3, nitric oxide (NO) and TNFα levels were estimated in both groups. Serum pentraxin-3, NO and TNFα were significantly increased in alcoholic cirrhosis patients compared to controls. Pentraxin-3 had a significant positive correlation with TNFα (r=0.303, P=0.039), Child-Pugh score (r=0.394, P=0.006) and MELD score (r=0.291, P=0.047) in alcoholic cirrhosis cases. Also we found positive association between NO with Child-Pugh score (r=0.391, P=0.007) and MELD score (r=0.311, P=0.033) in these cases. Linear regression analysis shows significant association of pentraxin-3 and NO (β=0.375, r2=0.141, P=0.009). We conclude that elevated pentraxin-3 and NO levels are associated with severity of alcoholic cirrhosis.
