Graft-versus-host disease, a complication of allogeneic bone-marrow transplantation, involves primarily the skin, liver and intestines, but may also be associated with pneumonia. To determine the relation of graft-versus-host disease with pneumonia, we evaluated the autopsies of 59 allogeneic and two autologous recipients and 74 control patients with various pulmonary diseases, who had not received a bone-marrow transplant. Lymphocytic bronchitis, characterized by lymphocyte-associated necrosis of the bronchial mucosa and often the submucosal glands, was present in 12 of 20 patients with Grade 2 or greater graft-versus-host disease but in only three of 39 with Grade 0 to 1 disease (P less than 0.0005). Onset of respiratory disease correlated with the time of onset of graft-versus-host disease. Patients with lymphocytic bronchitis had a higher incidence of bronchopneumonia and acute bronchitis of the lower respiratory tract. Lymphocytic bronchitis did not occur in the controls and appears to be a component of graft-versus-host disease that leads to bronchopneumonia, probably through destruction of the mucociliary apparatus.

Prognosis of second marrow transplantation after leukemia relapse is usually gloomy. We report a patient with AML who was successfully treated by the second marrow transplant following high dose busulfan, etoposide, and Ara-C for the testicular relapse after the first marrow transplantation. A 24-year-old man was diagnosed as having acute myeloid leukemia (AML) in September, 1988. In December of 1989 when he was in early relapse after his 2nd remission, he received the first allogeneic BMT from his HLA identical brother after high dose busulfan and cyclophosphamide conditioning. His posttransplant course was uneventful and graft versus host disease was not observed. Three months after BMT, he noticed swelling on right testicle. Leukemic cell infiltration was confirmed by aspiration cytology. The testicular relapse was followed by marrow relapse. After successful remission induction chemotherapy, he received 17.5 Gy testicular irradiation and second marrow transplantation using high dose busulfan, etoposide, and Ara-C conditioning. Although his posttransplant period was complicated by severe mucositis, high fever and bronchopneumonia, hematologic recovery was obtained by 3 weeks after the second transplant. He is now continuing in complete remission 18 months after the second BMT. This case report suggests that the combination of high dose busulfan, etoposide, and Ara-C could be a choice as a conditioning regimen for resistant AML relapsing after BMT.

A 36-year-old Hispanic man who had undergone allogeneic bone marrow transplantation, complicated by graft versus host disease, was admitted with acute gastrointestinal symptoms, including severe diarrhea and diffuse abdominal pain. He also had a persistent cough with sputum production. Blood cultures yielded Escherichia coli, and sputum cultures grew Apergillus species. The patient was treated with antifungal agents and broad-spectrum antibiotics. Despite aggressive medical therapy, the patient died 10 days after admission. Postmortem examination disclosed severe, bilateral confluent bronchopneumonia, with numerous septated branching hyphae consistent with Aspergillus species fungal organisms that involved the pulmonary parenchyma and tracheobronchial tree. Although the small and large bowels were only mildly congested, the entire gastric mucosa was covered with a 1.5-cm-thick pseudomembrane that contained numerous Aspergillus organisms. Our report represents the first description, to our knowledge, of a diffuse inflammatory pseudomembrane in the stomach, a complication that to date has only been associated with small and large bowel involvement.

Between November 1998 and October 1999 authors treated five multiple myeloma patients with an allogeneic peripheral blood stem cell transplantation from HLA-identical sibling using a non-myeloablative conditioning regimen. The median age at the time of transplantation was 58 (range: 47-65) years. In all patients one (n = 3) or two (n = 2) autologous peripheral blood stem cell transplantations were already performed. Conditioning was performed with fludarabine, oral busulfan and anti-T-lymphocyte globulin. All patients engrafted from 13 to 18 (median: 17) days from transplantation. The duration of neutropenia (absolute neutrophiles count < 500/microl) and thrombocytopenia (platelets < 20,000/microl) ranged between 4 and 19 (median: 18) and between 13 and 18 (median: 17) days, respectively. In the period of posttransplant pancytopenia two patients developed mild gastrointestinal mucositis and two pulmonary complications (bronchopneumonia and dyspnoe of unknown etiology). Two patients had grade III-IV acute graft-versus-host disease (GvHD), none had extensive chronic GvHD. Two patients received prophylactic donor-lymphocytes infusions 200 and 225 days from transplantation. One of them developed grade III acute GvHD. All patients responded. One achieved complete and four partial remission of the disease. One patient died 111 days from transplantation due to bronchopneumonia, four are alive and well, in the stable disease, 35, 36, 51 and 52 weeks after transplantation. It can be concluded that allogenic peripheral blood stem cell transplantation using a non-myeloablative conditioning regimen is an effective way of the multiple myeloma treatment with an acceptable toxicity.

Computed tomography (CT) is a powerful diagnostic tool for invasive aspergillosis (IA) after allogeneic stem cell transplantation (allo-SCT); however, little information is available concerning CT findings of late IA after allo-SCT. To characterize CT findings of late IA, we retrospectively examined medical records and high-resolution CT findings of 27 allo-SCT recipients with late IA. Either acute or chronic GVHD was diagnosed in 24 patients. All 27 patients were given corticosteroids at IA diagnosis. High-resolution CT findings included halo (n=12), centrilobular nodules (n=12), ill-defined consolidation (n=13), ground-glass attenuation (n=8), pleural effusion (n=7), pleural-based consolidation (n=4), and cavitation (n=4). CT findings showing centrilobular nodules and either halo or cavitation were classified into bronchopneumonia type and angioinvasive type, respectively. Angioinvasive-type, bronchopneumonia-type, and combination-type IA were diagnosed in 11, 8, and 4 patients, respectively. CT findings were nonspecific in the other 4 patients. One bronchopneumonia-type case and 2 angioinvasive-type IA cases were subsequently diagnosed as combination type. Although there were no significant differences in patient characteristics between the 2 types of IA, bronchopneumonia-type IA had a poorer prognosis than angioinvasive IA ( P=.022). Halo is a useful diagnostic marker in late IA as well as early IA, and late IA frequently manifests as bronchopneumonia.
