title: Potential of urinary neopterin excretion in differentiating chronic non-A, non-B hepatitis from fatty liver.
abstract: Urinary neopterin excretion was measured in 26 patients with histologically proven chronic non-A, non-B hepatitis (16 chronic persistent hepatitis, 10 chronic active hepatitis) and in 16 patients with steatosis. The potential of neopterin levels to discriminate between the two patient groups was compared with that of standard laboratory variables. Neopterin levels and triglycerides were shown to be the best variables for discriminating between the hepatitis and fatty liver patients, neopterin being the more specific of the two. Neopterin excretion in chronic persistent hepatitis was not statistically different from that in chronic active hepatitis. In the absence of specific tests, increased neopterin excretion seems to be a useful marker for diagnosing chronic non-A, non-B hepatitis and particularly in differentiating it from fatty liver.
