Summary

Increased neopterin levels in urine and serum of living humans indicate an activation of the cellular immune system. We investigated 119 urine and 48 serum samples from 129 corpses taken at necropsy; 29 cases with a background of cellular immune activation were compared to 100 corpses with no such indication. Our investigations show the feasibility of postmortem neopterin measurements. However, different kinetics of serum and urine concentrations after death were observed. In addition, the data show that urine and serum neopterin concentrations were significantly higher when cellular immunological abnormalities were present when compared to the control group and to living healthy controls. The findings suggest, that increased postmortem urine neopterin concentrations in necropsy indicate pathological processes linked with cellular immune activation.

Zusammenfassung

Erhöhte Neopterinspiegel in Serum und Harn Lebender sind ein Hinweis auf eine gesteigerte Aktivität des zellulären Immunsystems. Wir untersuchten 119 Harn- und 48 Serumproben von insgesamt 129 Leichen; bei 29 Fällen (Gruppe I) konnten Erkrankungen, die bekannterweise mit zellulären immunologischen Veränderungen einhergehen, festgestellt werden, bei den restlichen 100 Fällen (Gruppe II) lieferte die Obduktion keinen Anhalt auf derartige Erkrankungen. Die Auswertung unserer Ergebnisse ergab eine signifikante Erhöhung der Neopterinkonzentrationen in Serum und Harn in Gruppe I, sowohl gegenüber der Kontrollgruppe (Gruppe II) als auch gegenüber gesunden Personen. Da Neopterin im Harn zumindest über 24 Stunden post mortem stabil ist, könnte ein erhöhter Neopterinwert einen diagnostischen Hinweis auf eine Erkrankung, die mit zellulärer Immunaktivierung einhergeht, liefern.
