A clinicopathological study was carried out in 200 autopsied cases experienced in our department from 1981 to 1988. Cytomegalovirus infection was detected in 18 cases (9.0%). Eleven patients were male and 7 were female, and their ages ranged from 21 to 72 with a mean of 58.1 years. Primary diseases were mainly Non-Hodgkin's lymphoma (7 cases) and Adult T-cell leukemia (4 cases), and corticosteroid had been administered to all of them. The most commonly involved organ was lung (77.8%), followed by adrenal (55.6%), esophagus, pancreas, ovary (22.2%), stomach, small intestine, thyroid (16.7%), liver, kidney, tongue (11.1%), and so on. Concomitant infections were frequently complicated, which were bacterial pneumonia (5 cases), fungal pneumonia (3 cases), disseminated varicella-zoster infection (2 cases) and herpes simplex virus esophagitis or stomatitis (5 cases), while, ten patients died of cytomegalovirus pneumonia. Cytomegalovirus infection was one of the fatal opportunistic infections in immunocompromised, especially cell-mediated immunity impaired, hosts such as the patients with lymphocytic malignancies.

Twelve patients with hematological malignancies were treated with epirubicin and ten patients were evaluable. One out of our four patients with ALL, who had a previous therapy of anthracycline, achieved a partial remission (PR: 25%). In two patients with AML, remission was not obtained. Of four patients with NHL, one with B-cell lymphoma achieved complete remission (CR) and one with ATLL partial remission (CR + PR: 50%). Stomatitis was observed as a major side effect in three patients with acute leukemia and in one with NHL. In conclusion, our trial seems to show the efficacy of epirubicin in lymphoid malignancies.

We tried to transmit human T-cell leukemia virus type I (HTLV-I) into non-lymphoid cells and found that S+L- CCC cat cells were permissive for HTLV-I. Using these HTLV-positive cat cells, vesicular stomatitis virus (VSV) pseudotypes bearing envelope antigens of Japanese isolates of HTLVs were prepared and their reactivities with human or rabbit serum were examined. Japanese HTLV2M, HTLV10Y, and HTLVMT-2 pseudotypes and American HTLVPL pseudotype were neutralized by sera of Japanese and American patients with adult T-cell leukemia/lymphoma (ATL) and rabbit antisera against HTLV. Each serum showed similar antibody titers against different pseudotypes. Thus, envelope antigens of four HTLVs that reacted with the human and rabbit sera were considered to belong to a single serotype.

To determine if the immunodominant neutralizing epitopes on the external envelope glycoprotein of the recently identified sequence variants of human T cell leukemia/lymphoma virus type I (HTLV-I) from Melanesia are functionally conserved, sera from Japanese patients with adult T cell leukemia and from HTLV-I-infected Melanesians of Papua New Guinea and the Solomon Islands were tested for neutralizing antibodies by use of vesicular stomatitis virus pseudotypes bearing envelope antigens of Japanese and Melanesian HTLV-I strains. Neutralizing antibody titers of the Japanese and Melanesian sera and of monoclonal and polyclonal antibodies directed against a known neutralizing epitope on the external envelope glycoprotein of HTLV-I were equivalent against the Japanese and Melanesian HTLV-I pseudotypes. The demonstrated two-way cross-neutralization between Japanese and Melanesian strains of HTLV-I indicates that their antigenic determinants for neutralization are functionally indistinguishable and that HTLV-I exists as a single serotype worldwide.

Prophylaxis against human T cell lymphotropic virus type I (HTLV-I) is of primary importance for the eradication of adult T cell leukemia and other diseases associated with this virus. Hyperimmune globulin (H-IgG) prepared from healthy blood donors with high antibody titers for HTLV-I was evaluated for its prophylactic effect against HTLV-I in Japanese macaques (Macaca fuscata). Normal IgG (N-IgG) prepared from seronegative healthy blood donors was used as control. Both preparations contained 50 mg/ml IgG and H-IgG had a neutralizing antibody titer of 1:7100 by vesicular stomatitis virus (HTLV-I) pseudotype neutralization assay. Two macaques were infused with 2 ml/kg N-IgG and three macaques were immunized with 2-0.5 ml/kg H-IgG. They were immediately challenged by inoculation of 8 x 10(6)/kg cells from an HTLV-I-producing rabbit lymphoid cell line (Ra-1). Another macaque was immunized with 1 ml/kg H-IgG 24h after inoculation of 8 x 10(6)/kg Ra-1 cells. HTLV-I infection, as determined by seroconversion and verified by polymerase chain reaction, occurred in both of the N-IgG-injected macaques but in none of the four H-IgG-injected macaques. These results demonstrate the protective efficacy of H-IgG against HTLV-I infection in a primate model and provide an experimental basis for passive immunization trials in humans.

We estimated the utility of daily oral administration of etoposide (ETOP) in 25 cases of refractory hematological malignancies who had been admitted to our hospital between February, 1988 and October, 1995. Patients were 9 cases of malignant lymphoma, 7 cases of adult T cell leukemia (ATL), 7 cases of acute leukemia, 1 case of primary macroglobulinemia, and 1 case of chronic lymphocytic leukemia (CLL). Eight cases were elderly patients over 65 years old, 7 cases were refractory to previous chemotherapies, and 13 cases were relapsed cases. ETOP was administered at 25 or 50 mg per day for at least more than 3 consecutive weeks, if the peripheral white blood cell count exceeded 1,000/microliter. Complete and partial responses were obtained in 64% of all cases, especially in 81% of malignant lymphoma and ATL. Probability of survival for 3 years of malignant lymphoma and ATL was 36.7%. As mild toxicities, 2 cases (8%) had nausea and vomiting, 2 cases (8%) had diarrhea, and 3 cases (12%) had stomatitis. Grade 3 leukocytopenia was observed in 16% of cases. Twelve out of 16 evaluable patients recovered in performance status (PS) after this therapy. Daily oral administration of ETOP might be an effective therapy for refractory hematological malignancies, especially for malignant lymphoma.

We examined the effects of polycations, namely, diethylaminoethyl-dextran (DEAE-dextran) and hexadimethrine bromide (Polybrene), on infection with the retroviruses human T cell leukemia virus types I and II (HTLV-I and HTLV-II) and human immunodeficiency virus type 1 (HIV-1). The plating of vesicular stomatitis virus (VSV) pseudotype bearing envelope antigens of HTLV-I [VSV(HTLV-I)] was inhibited about 2- and 10-fold by treatment with DEAE-dextran and Polybrene, respectively. The formation of HTLV-I viral DNA detected 1 day after infection was also inhibited by these polycations. In contrast, polycations enhanced the plating of the VSV (HTLV-II) pseudotype two- to threefold. The polycations did not affect the plating efficiency of HTLV-I or HTLV-II when added after virus adsorption. Infection of human T cell lines, peripheral blood lymphocytes (PBLs), or brain-derived cells with syncytium-inducing (SI) types of HIV-1 strains (GUN1 and IIIB) was inhibited 3- to 20-fold by polycations. However, infection of PBLs or monocyte-derived macrophages with the macrophage-tropic Ba-L or SF162 strain was enhanced 1.5- to twofold by polycations. On the other hand, syncytium formation in coculture induced by HTLV-I, HTLV-II, or HIV-1 was enhanced two- to threefold unanimously by DEAE-dextran or Polybrene. Although polycations have been used to potentiate human retrovirus adsorption, they inhibited infection of cell-free HTLV-I or SI-type HIV-1 strains.
