[Clinical usefulness of polyamino acid particle agglutination test for detection of anti-HTLV-I antibody].

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.

[Prevention of stomatitis in patients with acute myelogenous leukemia using PVP-iodine (Isodine) gargle].

From November 1987 to October 1990, we investigated the efficacy of povidine iodine gargle solution (Isodine Gargle) for preventing stomatitis in 26 patients (19 males and 7 females; mean age 53.2 years) with acute myelogenous leukemia (AML). The patients were given a concentrated preparation of the gargle solution which they had to dilute 50 times, and were asked to use it 8 times/day for one year. Twenty patients (76.9%) frequently suffered from stomatitis despite the gargling. Therefore, in the second year they were instructed to use the gargle solution at a higher concentration (30-fold dilution). On the third year, they were asked to increase the frequency of gargling to 10 times/day; this resulted in a significant decrease in frequency of the episodes of stomatitis. Severe and painful stomatitis no longer occurred. Gargling with povidine iodine gargle solution was thus considered effective for preventing stomatitis in AML patients.

[Evaluation of specificity of EIA kit (ED-007)].

EIA (Eitest: Eisai) and Gelatin Particle Agglutination: PA (SERODIA: Fujirebio) assays were performed for the detection of HTLV-I antibodies with 10,780 sera from patients since 1986. Eleven point five percent were reactive by both EIA and PA, while 1.1% was PA(+), EIA(-), these PA false positive occurred on low titer. Conversely 0.2% on EIA positive seems PA false negative because of Western blot (WB) positivity. Zero point nine percent was EIA(+), PA(-), of these 80.6% were not inhibited by EIA confirmatory test. The main cause of EIA false positive was due to reactivity of auto antibody with MT-2 cell lysate. We used new EIA (ED-007: Eisai) coated with HTLV-I antigen purified from supernatant of culture medium of MT-2 cell. The results completely matched with EIA confirmatory test and WB. Cut off index value of sera from SLE patients were down to 0.2 (mean +/- SD) from 0.7 +/- 0.4 of Eitest ATL. EIA (ED-007) are probably useful and more specific assays for the detection of HTLV-I antibodies, especially, the sera of patients with autoimmune diseases.
