[Increased urinary excretion of neopterin in patients with malignant tumors and with virus diseases (author's transl)].

Heightened urinary concentrations of neopterin were detected in patients with malignant tumors. The levels of neopterin were quantified by high performance liquid chromatography. The normal range for male individuals was 280 +/- 1,7 ng neopterin/mg creatinin, for women 340 +/- 116 ng neopterin/mg creatinin. The values found in patients with malignant tumors were 1370 +/- 495 ng neopterin/mg creatinin and in patients with virus diseases 1637 +/- 696 ng neopterin/mg creatinin.
