A 44-year-old woman with malignant T-cell lymphoma and secondary leukemia received an allogeneic bone marrow transplant (BMT). She had received BMT conditioning treatment with total body irradiation and chemotherapy. Hemoptysis and progressive dyspnea developed 11 days after the transplant. A chest roentgenogram showed bilateral diffuse infiltrates. Bronchoalveolar lavage fluid was bloody, and diffuse alveolar hemorrhage (DAH) was diagnosed. Respiratory failure progressed despite mechanical ventilation and administration of corticosteroids. The patient died 58 days after the transplant DAH after BMT has been recognized in western countries as a syndrome with high mortality. We draw attention to the fact that DAH is a serious early pulmonary complication of BMT also in Japan.

We report a patient with adult T-cell leukemia (ATL) complicated with intestinal tuberculosis. A 57-year old man was admitted to our hospital because of fever and dyspnea. He was diagnosed as ATL by leukocytosis [leukocyte count 18,200/microliters with 56% of abnormal lymphocytes which express CD4(+) and CD25(+)] and seropositive result of anti-HTLV-1 antibody. Combination chemotherapy for ATL improved his serum LDH level and peripheral lymph nodes, but fever was still persistent. He had an emergency operation because of perforation of the cecum during the chemotherapy. Histological examination of the resected cecum revealed caseous necrosis and numerous mycobacterium, which induced a diagnosis of intestinal tuberculosis. Although there have been several reports on pulmonary tuberculosis in patients with ATL, this is the first report of intestinal tuberculosis in ATL as far as we know. We conclude that if the patients with ATL have persistent fever of unknown origin, we should take account of intestinal tuberculosis as one of differential diagnosis.

A 46-year old man was admitted complaining of dyspnea. Physical examination revealed superficial lymph nodes swelling, and coarse crackles over the lung. Chest X-ray film showed diffuse small granular shadows, suggesting diffuse panbronchiolitis (DPB). Peripheral blood smears showed cells with flower like nuclei. HTLV-I antibody was positive in the serum. He was diagnosed as having adult T-cell leukemia (ATL). Transbronchial lung biopsy showed diffuse infiltration of mononuclear cells around bronchioalveoli. The mononuclear cells stained positively for Pan T, CD2, CD3, CD4, CD5, CD25, and DNA from the cells showed HTLV-I provirus monoclonal integration. This is a rare case of ATL accompanied by DPB-like bronchioalveolar ATL cell infiltration.

Chondronecrosis of the cricoid cartilage is a rare complication of intubation. The records of two children were reviewed. An 8-month-old girl with myelomonocytic leukaemia developed chondronecrosis 10 days after a 2-day period of ventilation. A 4-year-old girl comatose after poisoning by the histamine antagonist, alimemazine, developed chondronecrosis after a 2-day period of intubation. The complication was suspected when extubation led to dyspnoea owing to laryngeal stridor and was confirmed by direct laryngoscopy. We review the development of the condition, the causative factors, treatment and prevention.

Anti-CD7-dgA, DA7, consists of deglycosylated ricin A chain coupled to a mouse monoclonal anti-human CD7 antibody. This study determined the maximally tolerated dose (MTD) of this immunotoxin administered as a one hour infusion over five days to 11 patients with T-cell lymphoma (>30% CD7+ malignant cells). The MTD was 0.2 mg/kg/day or 1 mg/kg/120 hours (maximal toxicity grade 3) with vascular leak syndrome (VLS) as dose-limiting toxicity (DLT). Predictors of severe VLS included age and absence of circulating lymphoma cells. Two partial responses and one minimal response were seen. Patients with minimal lymphoma burden or T-cell large granular lymphocyte (LGL) leukemia showed the best responses. The mean maximal serum concentration of immunotoxin at the MTD was 2.5 ug/ml. The mean alpha-phase half-life was 1.5 hours and the mean beta-phase half-life was 8 hours. Repeated dosing had minimal effects on either peak serum immunotoxin concentrations or serum half-lives. While human antimouse antibodies were observed, they were low in concentration (<55 ng/ml). Human anti-ricin antibody was elevated in one patient (190 ng/ml). VLS presented with hypoalbuminemia, dyspnea, pulmonary edema, aphasia, and peripheral edema and cleared over a two week period. Serum fibronectin levels were measured in three patients and were very low in one patient who developed VLS. No specific binding of DA7 immunotoxin was seen with vascular endothelium in various human tissues.

A retrospective study of 37 patients with haematological malignancy (21 acute myeloid leukaemia, 11 acute lymphoid leukaemia, two lymphoma, two hairy cell leukaemia, one Hodgkin's disease) and histologically documented mucormycosis was conducted to evaluate the clinical characteristics and ascertain the factors which influenced the outcome from mycotic infection. Patients were admitted to 18 haematology divisions in tertiary care or university hospitals in Italy between 1987 and 1995. Fever, thoracic pain, dyspnoea and cough were the most frequent presenting symptoms. At the onset, 89% patients were neutropenic (neutrophil counts < 0.5 x 10(9)/l) with a median duration of previous neutropenia of 14 d (range 6-60). The most frequent sites of infection were lungs (81%), CNS (27%), sinus (16%), liver (16%) and orbital space (10%). Only three patients were asymptomatic. A correct in vivo diagnosis was made in only 13 (35%) patients. When performed, thoracic and cranial CT scan were the most useful diagnostic investigations. Despite the fact that 26 febrile patients were treated with empirical antifungal treatment, 28 of the 37 patients (76%) died from fungal infection at a median time of 17 d from the onset of clinical symptoms. Nine patients were cured by antifungal therapy plus, in five cases, radical surgery procedures. An analysis of factors influencing outcome demonstrated that the resolution of chemotherapy-induced neutropenia and prolonged treatment with amphotericin B and, if feasible, radical surgical debridement treatment, were significantly correlated with recovery from infection. Mucormycosis, a rare filamentous fungal infection that occurs most frequently in neutropenic acute leukaemia patients, is characterized by a high mortality rate. Extensive and aggressive diagnostic and therapeutic procedures are essential to improve the prognosis in these patients.

A 16 year old man underwent an allogeneic bone marrow transplantation (BMT) from an HLA identical sibling donor for acute lymphoblastic leukaemia in 1984. He developed chronic graft versus host disease involving the skin and kidneys. At day 400 after BMT his condition was complicated by obstructive airways disease, which was partially responsive to azathioprine and steroids. Five years after withdrawal of immunosuppressive treatment he developed dyspnoea and decreased pulmonary function test results, and steroid treatment was resumed. Fibrobronchoscopy revealed the presence of a mucoepidermoid carcinoma in the left main bronchus. After surgical laser resection, there was gradual clinical and functional improvement. There was no evidence of recurrence one year after surgery.

Malignant pericardial effusion is an uncommon disorder and is usually caused by far advanced lung cancer, breast cancer, lymphoma and leukaemia. Pericardial effusion in recurrent gastric cancer has been reported in only three patients. We report the case of a 53-year-old male with sudden onset of dyspnoea, pericardial effusion and cardiac tamponade and the unexpected and the asymptomatic concurrence of gastric cancer. Recurrent haemorrhagic pericardial effusion with physical signs of cardiac tamponade as the initial and only clinical manifestation of gastric cancer has not been described previously.

In three patients, a man aged 34 with aids, a woman aged 67 with recurrent major dyspnoea and a woman aged 73 with chronic lymphatic leukaemia, examination revealed progressive dyspnoea while the chest X-rays showed infiltrative lesions in both lungs. In view of the inadequate response to the treatment administered, an open lung biopsy was performed, following which the diagnosis could be made. Adequate treatment was then started and followed by clinical recovery. It is not clear if open lung biopsy carries higher risks of mortality and morbidity than biopsy by means of flexible bronchoscopy. Open lung biopsy more often leads to a classifying diagnosis. For collection of endobronchial or transbronchial biopsy samples in ununderstood diffuse interstitial lung diseases, flexible bronchoscopy is the method of first choice. Open lung biopsy is a justified supplementary examination, at any rate in severely ill, immunocompromised patients who require adequate therapy without delay.

In this pilot trial of interleukin (IL)-2-treated autologous bone marrow (BM) and peripheral stem cell (PSC)-supported high-dose chemoradiotherapy, we report 36 patients with poor-prognosis leukemia and lymphoma who received BM and/or granulocyte colony-stimulating factor (G-CSF)-mobilized autologous PSCs that had been exposed to IL-2 for 24 hours ex vivo. Patients then received IL-2 by low-dose continuous intravenous (i.v.) infusion until hematologic reconstitution and then by intermediate-dose continuous i.v. infusion for six 2-week maintenance cycles given at 1-month intervals. The median Day to neutrophils over 500/microL was 22 with BM and 10 with PSCs (p = 0.01). The median Day to platelets >20,000/microL was 50 for BM and 25 for PSCs, and to platelets >50,000/microL was 138 for BM and 34 for PSCs (p not significant). After the first three patients received IL-2 at 2 mIU x m(-2) x day(-1) and had slow reconstitution, four patients were treated without IL-2 until the maintenance phase following reconstitution. The remaining 29 patients received the initial "post-infusion" IL-2 at 1 mIU x m(-2) x day(-1). Toxicities associated with the infusion of IL-2-activated cells consisted of chills and fever in about one-half of the patients and transient hypotension in 12%. Low-dose IL-2 by continuous i.v. infusion in the early posttransplant period was associated with exacerbation of fever, diarrhea, and altered mental status in a minority of patients. The major dose-limiting toxicities of maintenance IL-2 were fever, fatigue, gastrointestinal symptoms, skin rash, and dyspnea. Among 24 lymphoma patients, nine are in continuous complete remission (CCR) from 18-48 months, and 15 have died (12 due to relapse and three of therapy-related toxicities). Of 12 acute leukemia patients, two with acute lymphoblastic leukemia (ALL) are in CCR at 38 and 43 months, and one patient who was in cytogenetic but not molecular remission of Philadelphia chromosome-positive ALL died of progressive leukemia at Day 108. Three of nine with myeloid leukemia are in CCR at 21, 46, and 53 months; one is in hematologic and cytogenetic remission of acute promyelocytic leukemia at 55 months with multiple new cytogenetic abnormalities; one is alive at 54 months with pancytopenia after incomplete hematologic recovery followed by multiple new cytogenetic abnormalities (myelodysplasia); and one had an unrelated donor transplant after relapsing 4 months following protocol therapy. One myeloid leukemia patient remains without evidence of relapse, but is transfusion-dependent at 15 months following transplant.
