In order to investigate the character of pulmonary complications in patients with adult T-cell leukemia (ATL), a pathological and bacteriological study was performed in 92 autopsy cases with hematologic malignancies including 17 cases of ATL and 103 autopsy cases with solid malignancies from 1981 to 1990. Among 17 cases with ATL, pulmonary complications were seen in 16 cases (94.1%); pulmonary infection in 14 (82.3%), leukemic cell pulmonary infiltration in 9 (52.9%), pulmonary hemorrhage in 5 (29.4%), pulmonary alveolar calcinosis in 2 (11.8%), and idiopathic interstitial pneumonia in 2 (11.8%). The causative microorganisms were virus in 10; 9 of which were cytomegalovirus, followed by bacteria infection in 4 cases, mainly pseudomonas aeruginosa, and fungal infection in 3, mainly cryptococcus. pneumocystic carinii and mycobacterium tuberculosis were not detected. It is suggested that patients with ATL are severely compromised with chiefly cellular immunodeficiency, and administration of sulfamethoxazole-trimethoprim and isoniazid is very effective in prevention of pneumocystis carinii pneumonia and pulmonary tuberculosis.

Hepatomegaly and deranged liver functions are common findings in reactive haemophagocytic syndrome (RHS). We report the findings of 12 fatal cases of RHS in which histological materials of the liver are available for study. The underlying diseases of these patients included lymphoma/leukaemia (6 cases), disseminated undifferentiated carcinoma of the ovary (1 case), disseminated nasopharyngeal carcinoma complicated by tuberculosis (1 case), adenovirus pneumonia (1 case), pneumococcal pneumonia (1 case), typhoid fever (1 case), and possible drug intoxication (1 case). Ten patients had involvement of the liver by the underlying disease process which contributed to the marked hepatic derangement. Non-specific reactive hepatitis, sinusoidal dilatation and steatosis resulting from systemic or local effects of the associated diseases and the haemophagocytosis also added to the high incidence of liver abnormalities. A diffuse Kupffer cell hyperplasia with haemophagocytosis is characteristic of the syndrome, as all the cases showed increased numbers of bland-looking histiocytes within the hepatic sinusoids and haemophagocytosis which was moderate to marked in 8 cases and mild in 4. Thus the finding of Kupffer cell hyperplasia with prominent haemophagocytosis in liver biopsy is indicative of an element of RHS and warrants clinical monitoring. Differential diagnoses of haemophagocytosis in liver are also discussed.

The role of selected prior medical conditions in the etiology of hematopoietic malignancies was examined in a case-control study of members of two regional branches of the Kaiser Permanente Medical Care Program (USA). Past history of chronic infectious, autoimmune, allergic, and musculoskeletal disorders was abstracted from medical records for leukemia (n = 299), non-Hodgkin's lymphoma (NHL, n = 100), and multiple myeloma (n = 175) cases and matched controls (n = 787). Little difference was found between cases and controls for most of the chronic conditions evaluated, including sinusitis, carbuncles, urinary tract infections, pelvic infections, herpes zoster, asthma, rheumatoid arthritis, psoriasis, bursitis, and gout. Only three statistically significant elevated risks were found, i.e., with combined disc disease myeloma among patients with prior eczema and disk and other musculoskeletal conditions, and NHL following tuberculosis. Only two of these associations showed consistent patterns by sex and geographic region (myeloma with eczema and with musculoskeletal conditions). While prior history of eczema and musculoskeletal conditions may slightly increase risk of myeloma, this study provided little if any support for an association of chronic infectious, autoimmune, allergic, and musculoskeletal conditions with subsequent occurrence of the leukemias or NHL. Additionally, these data did not support a role for chronic antigenic stimulation, as defined in previous epidemiologic studies, in the etiology of hematopoietic malignancies.

A Japanese patient with adult T-cell leukemia-lymphoma (ATL) showed a disease progression from the smoldering type to the chronic type and finally to the acute type. The patient was variously treated, including 2'-deoxycoformycin, with some beneficial effects. During the chronic type he developed a composite lymphoma consisting of T-cell lymphoma (ATL) of medium-sized cells and B-cell lymphoma of diffuse large cell type. At that time, he also suffered from miliary tuberculosis and adenovirus type 11-induced hemorrhagic cystitis, indicating that he was in a marked immunodeficient state. Southern-blot analysis revealed that the two malignancies have distinct clonal origin on the basis of the following results: (1) clonally rearranged T-cell receptor beta-chain gene (TcR-beta gene) and germline configuration of immunoglobulin heavy chain gene (IgH gene) in ATL leukemic cells, (2) clonal rearrangement of IgH gene in lymphoma cells, indicating a monoclonal B-cell lymphoma, (3) monoclonal integration of HTLV-I provirus in ATL leukemic cells, (4) definite presence and monoclonal origin of EBV genome in lymphoma cells. This is the first report of secondary EBV genome carrying monoclonal B-cell lymphoma in an ATL patient. It is suggested that the immunodeficient state in the patient with ATL allows the emergence of EBV-related B-cell lymphoma.

A 77-year-old man, who had been a subway construction worker, was admitted to our hospital for surgical treatment of left cheek carcinoma and an examination for pancytopenia on November 17, 1986. Bone marrow aspiration revealed that 10% of the nucleated cells were blasts with morphological atypism. Bone marrow biopsy showed hypocellular marrow and a diffuse increase of argyrophil fibers with the presence of asbestos fibers was observed by microscope. A chest X-ray showed the findings of old tuberculosis and pulmonary asbestosis, and asbestos fibers were demonstrated in the broncho-pulmonary lavage fluid. He was diagnosed to have pulmonary asbestosis complicated with hypoplastic low percentage leukemia.

Eighteen patients with leukemia have received HLA-identical allogeneic bone marrow transplantation (BMT) at our hospital since 1981. Fifteen of these patients have been living without relapse. for prophylaxis of GVHD, MTX was used in 8 patients, and cyclosporine (CSP) together with MTX in 6 patients, 3 received multiple agents at much smaller dosage, including monoclonal antibody. All patients received intravenous placental gamma-globulin, and 16 received garlic extract. Three patients died. One, who neither received MTX, nor CSP died of hyperacute GVHD, one who did not receive garlic extract died of GMV pneumonia, and the third one died of tuberculosis 18 months after BMT.

This paper intends to present an overview concerning the risks and benefits of BCG-immunisation basing on a research of the actual literature. The historical controversy is well known, but regarding the epidemiological situation with respect to morbidity and mortality of tuberculosis in Middle and Western Europe by now it seems to be necessary again to reflect on vaccination recommendations. While complications after vaccination may be serious or even life-threatening, immunization with BCG seems to have a beneficial effect on the incidence of infantile leukemia. Nevertheless, this effect is discussed controversially on recent research. In addition there should be drawn special attention to the problem of life-vaccines, in particular of BCG under the view of the increasing number of children with acquired immunodeficiencies.

In 13 cases of leukemia, different clinical forms showed pleuropulmonary and mediastinal lesions consisting in: mediastinal-hilar adenopathies without the parenchyma involvement (2 cases), with involvement of the pulmonary parenchyma (6 cases) and only one case of pulmonary lesions without adenopathies. In 3 cases leukemia overlapped pulmonary TB, TB sequela (2 cases) or active-evolutive TB (1 case). One case developed to bronchopulmonary neoplasm. While the treatment of parenchymatous complications, appeared by nonspecific infections, and of the single case of active tuberculosis proved adequate, the ganglionic-mediastinal lesions continued their acute or chronic unfavourable evolution.

Natural killer (NK) cell activity is capable of mediating an antileukaemic effect. Accordingly this phenomenon was studied during the course of the 13-year disease-free survival of a patient after treatment for acute non-lymphoblastic leukaemia in order to test the hypothesis that concurrent tuberculosis may have induced this cell population and thereby modulated clinical and haematological course of the disease. An unusually high spontaneous cytotoxicity was demonstrated, which may have played a role in the prolonged survival. This latter finding is consistent with the theoretical possibility that chronic inflammation may enhance the activity of this particular cell population and supports the concept that therapeutic modulation of NK activity remains an achievable goal in clinical medicine.

Three cases of pulmonary atypical mycobacteriosis (AM) were reported. Two cases were associated with lung cancer in which the diagnosis of malignancy was difficult and delayed by the coexistence of AM. The third was a case of adult T-cell leukemia (ATL) which manifested during the course of AM. In case 1 (73 years, male) and case 2 (86 years, male), chest roentgenogram abnormalities as well as clinical symptoms were considered to be caused by mycobacteriosis because of positive smear of acid-fast bacilli in sputa on admission. Therefore it took four months and three months respectively for final diagnosis of lung cancer. The autopsy of case 1 revealed a poorly differentiated adenocarcinoma with coexisting foci of squamous cell carcinoma in right lower lung, and granulomatous inflammations with caseating necroses in right mid and lower lungs. M. avium complex was cultured from sputum on admission, and also a high titer of HTLV-I antibody was demonstrated. In case 2 malignant cells were detected in sputa (class V), however his general condition did not allow an aggressive anticancer chemotherapy and he died of malignancy with complication of thromboangiitis obliterans on right lower leg. Case 3 was a 76-year-old male who had been diagnosed as lung AM for more than two years. His chest radiography showed bilateral infiltrative shadows with frequent positive cultures of M. avium complex (more than 100 colonies) from sputum. A generalized lymphadenopathy including right hilar lymph node on chest X-ray film was followed by the presence of atypical lymphocytes in peripheral blood and the elevation of HTLV-I antibody in serum. Four months later he died with hypercalcemia and renal failure in spite of chemotherapy (CPM + VCR + ADR + PLS). The above cases suggest that AM as well as tuberculosis should be considered when pulmonary infiltrates were observed in malignant patients, especially in patients with retrovirus infections.
