HTLV-III-Durchseuchung bei Personen mit intravenösem Drogenmißbrauch: Korrelation von Antikörpern gegen HTLV-III mit Neopterin und TH/TS

: Antibodies against HTLV-III, neopterin levels in blood and urine, TH/TS ratio and hepatitis marker were determined in 34 clinically symptom-free persons known to be intravenous drug abusers. 15 persons were positive in the ELISA and Western-blot tests. There was a strong reaction to protein p24 compared with that to protein p41. In 12 of 14 persons who were antibody-positive the neopterin level in morning urine was elevated; an abnormal TH/TS ratio was present in nine of 13 persons. In future, determination of neopterin and of antibodies against certain proteins of HTLV-III may make it possible to provide a simple way of prognosticating on the course of an HTLV-III infection.
