Clinical significance of urinary neopterin in chronic liver disease

ABSTRACT

Increased neopterin concentration in serum, urine and other biological fluids have been reported in conditions causing stimulation of cellular immunity with increased macrophage activity. Assessment of neopterin production in these conditions conveys useful information on disease activity and prognosis. In our study, urinary neopterin was measured in 40 patients with liver cirrhosis of different etiologies other than hepatitis B infection and 30 controls. The results showed high significant statistical difference between group I [HCV with viremia], group II [HCV without virenlia], group III [HCV+viremia+Bilharziasis] [P<0.001] and significant statistical difference for group IV [Bilhraziasis without HCV] [P<0.05] compared with the control group. The highest mean value of urinary neopterin was in group 1 [299.98 +/- 94.785] which was significantly higher than group II [216.18 +/- 37.55] and group IV [201.29 +/- 52.46] [P<0.05] no statistical difference with group III [226.56 +/- 80.18] [P> 0.05]. In conclusion, urinary neopterin has proved to be a simple and reliable method which helps in the diagnosis of activity in chronic HCV infection in patients with chronic liver disease
