ABSTRACT
A new artificial carrier particle agglutination test using polyamino acid (polyamino PA) was developed for anti HTLV-I assay. We carried out the comparative study on anti-HTLV-I among polyamino PA, gelatin PA, EIA and WB methods. All of 76 ATL, 20 HAM/TSP, 53 patients with uveitis and 50 HTLV-I carriers were seropositive and 50 HTLV-I non carriers were seronegative with four methods. Eighteen of 503 patients include autoimmune diseases showed seropositive by polyamino PA and gelatin PA. One of 19 seropositives by EIA was false positive. All of 25 sera showed non-specific reaction by the gelatin PA were clearly negative by the polyamino PA. This is due to the fact that the polyamino acid particle has a greater specific gravity as carrier. The final judgement was got within 45 minutes. It was earlier more 30 minutes than the gelatin PA. The polyamino PA is a simple, rapid, sensitive and specific method. Therefore, it is useful for mass screening and clinical diagnosis.

Investigation for prevalence of antibodies to hepatitis C virus (HCV) and to Treponema pallidum was conducted in 883 females with gynecologic disorders who were admitted to the gynecological ward of the Department of Obstetrics and Gynecology, Siriraj Hospital during April to August 1991. The study population consisted of 678 patients with malignancies and 205 patients with benign diseases. Anti-HCV antibody was found in 3.1% of the cases with malignancies and 1.46% of those with benign diseases. Among the gynecologic malignant group, the patients with carcinoma of cervix had the highest prevalence of HCV antibody (3.6%). The positive serologic tests for syphilis in patients with carcinoma of cervix (9.8%) were significantly higher from those in patients with ovarian carcinoma (3.75%) (p < 0.01). There were 3 cases with carcinoma of cervix who were simultaneously sero-positive for both HCV and syphilis.

We evaluated Retrovirus EIA kit (Roche Co.), in which virus components of three different viruses, HIV-1, HIV-2, and HTLV-I were used antigens. All the specimens from the patients with ATL, HAM, HTLV-I carrier, AIDS and AC, and from HIV-2 infected individuals were found to be positive. Four out of 40 specimens from hemophiliacs not infected with HIV-1 were found out to be positive. These specimens were confirmed to contain antibody against HTLV-I. Pseudo-negative or -positive reactions were not found in this study. Therefore, Retrovirus EIA kit should be evaluated more extensively, for the possible applications for screening of blood donors, and for selecting the sources of blood products as well as for clinical diagnoses.
