title: [The clinical importance of the dynamic determination of the serum neopterin level in patients with dilated cardiomyopathy].
abstract: Serum neopterin was measured over time (from 3 to 24 months) by RIA in 15 patients with dilated cardiomyopathy. Comparison with the clinical data revealed that the initially normal concentration of neopterin (less than 9 nM/l) was associated with a stable disease course on a long-term observation (group I). The second group with an initially high neopterin concentration showed an objective improvement of the health status together with normalization of the neopterin level. The third group of patients were characterized by an increase of the neopterin level measured over time, coupled with a disease progress. It should be noted that 5 out of 8 patients died. In addition to neopterin measurements, the patients with dilated cardiomyopathy were examined for serum beta-2-microglobulin (beta-2M). Analysis of the data obtained has demonstrated a similar relationship between the level of neopterin and beta-2M and the clinical course of dilated cardiomyopathy. Still, neopterin is a more sensitive marker. Therefore, the data obtained attest to a possibility of the use of serum neopterin as a prognostic marker in patients suffering from dilated cardiomyopathy.
