An acute pulmonary syndrome possibly representing acute graft-versus-host disease (GVHD) involving lung interstitium occurred in a patient given an allogeneic bone marrow transplant for haematological malignancy. He presented at day 34 with acute GVHD of skin and bowel, and this was associated with cough, dyspnoea and an asymmetrical change on chest X-ray. Lung biopsy demonstrated an interstitial and peribronchial lymphocytic infiltrate and acute bronchial epithelial degeneration. He responded symptomatically to high dose intravenous methylprednisolone. The radiological change resolved completely. This case, thought to represent GVHD involving lung interstitium, emphasizes the need for tissue procurement in the management of non-bacterial lung disease after marrow transplantation.

Lung disease in patients with severe combined immune deficiency (SCID) undergoing bone marrow transplantation (BMT) is most commonly caused by infection. Noninfectious episodes of pulmonary disease following BMT are more frequently encountered in patients with hematologic disorders or malignancy and are probably related to ablation therapy or graft-versus-host disease (GVHD). In contrast, patients with SCID do not receive chemotherapy before an HLA-identical allogeneic BMT and they do not suffer significant GVHD. We report a patient who developed severe lung disease during the period of rapid engraftment following an HLA-identical allogeneic bone marrow transplantation. Lung biopsy showed dense lymphocytic infiltrates in the alveolar septae and no evidence of infection. Following the idea that the acute recruitment of engrafted lymphocytes may have contributed to or caused the pulmonary disease, we have attempted to suppress cellular immunity by administering high-dose methylprednisolone. The patient's lung disease rapidly improved and eventually completely resolved.

A 2-year-old boy underwent bone marrow transplantation for severe aplastic anemia. Eighteen months later he developed chronic lung disease and dryness of the eyes. Ophthalmologic examination revealed obstruction of the nasolacrimal ducts and marked dilatation of the lacrimal sacs bilaterally. It seems likely that the nasolacrimal duct obstruction was a manifestation of chronic graft-versus-host disease.

To describe the clinical presentation and progression of obstructive lung disease after marrow transplantation, we examined a sequential sample of 35 patients who had allogeneic marrow transplantation between January 1980 and January 1987, were 16 years or older, had normal pulmonary function tests before transplantation, and developed airflow obstruction defined as FEV1/FVC less than 70% and FEV1 less than 80% predicted 50 days or more after transplantation. Cases were selected from 1029 adult (older than 16 years) patients who underwent allogeneic marrow transplantation during the same period. Patients with airflow obstruction presented with symptoms of cough, dyspnea, or wheezing, or a combination. In 80% the chest radiograph was normal. Airflow obstruction was diagnosed within 1.5 years after transplantation in 33 of 35 patients. Clinical, extensive, chronic graft-versus-host disease was present in 24 patients. Only 4 patients had a complete response to primary therapy of chronic graft-versus-host disease. Serum IgG and IgA levels were decreased in 15 and 25 patients, respectively. The FEV1 declined rapidly (decrease in FEV1 greater than 30% between tests) in 21 patients, but 14 patients with slowly progressive or reversible disease were identified. Mortality was 65% at 3 years after transplant, a significantly higher value (P = 0.016) than the 3-year mortality rate of 44% in a comparison group of 412 concurrent patients with chronic graft-versus-host disease who were 16 years or older, survived more than 80 days after transplantation, and had normal pulmonary function. We concluded that obstructive lung disease after marrow transplantation may be variable with respect to time of onset and rate of progression. Obstructive lung disease was frequently associated with serum immunoglobulin deficiency and clinical, extensive, chronic graft-versus-host disease that was not readily responsive to treatment. Mortality was high but long-term survivors were identified.

The severity of the graft-versus-host (GVH) reaction, judged by splenomegaly and immunosuppression, was augmented by murine cytomegalovirus (MCMV) infection. Profound GVH-induced immunosuppression was seen in adult unirradiated MCMV-infected F1, mice even after challenge with extremely low doses of parental spleen cells. Mice receiving MCMV+GVH challenge died from days 16-21, with interstitial pneumonia being the most prominent pathological lesion. Pulmonary disease was unrelated to levels of viral replication in the lung. These results suggest that in human marrow recipients, cytomegalovirus infection may play a primary role both in provoking or accentuating GVH disease, as well as in the development of interstitial pneumonia.

Obstructive lung disease is a complication of bone marrow transplantation. To identify risk factors we analyzed pulmonary function tests of 281 adult patients 1 year after marrow transplantation. The forced expiratory volume at 1 second divided by the forced vital capacity (FEV1/FVC) was used to measure airflow rates. Factors associated with a lower year-1 FEV1/FVC (%) included increased age (p less than 0.0001), male gender (p = 0.02), cigarette smoking (p = 0.01), lower FEV1/FVC before transplantation (p less than 0.0001), HLA-nonidentical grafts (p = 0.001), chronic graft-versus-host disease (p = 0.0002), and immunosuppressive therapy with methotrexate (p = 0.01). There was no significant association between the year-1 FEV1/FVC and underlying disease, dose of conditioning irradiation, or development of acute graft-versus-host disease. Linear multivariate regression analysis, after controlling for the FEV1/FVC before transplantation, shows both chronic graft-versus-host disease and administration of methotrexate independently associated with decrements in the year-1 FEV1/FVC. The combined occurrence of chronic graft-versus-host disease and methotrexate also was strongly associated with decreases in the year-1 FEV1/FVC, indicating an interaction of these risk factors.

A 19-year-old woman with extensive, persistent chronic graft versus host disease (GVHD), following an HLA-identical bone marrow graft for acute leukemia, developed rapidly progressive airflow obstruction 140 days post-transplantation (PT) and presented clinically with persistent cough, inspiratory rales, bronchospasm and exertional dyspnea. Pulmonary function tests (PFT) showed rapidly evolving severe airflow obstruction and hypoxemia without restrictive ventilatory defect. Open lung biopsy on the 204th day PT confirmed focal bronchiolitis obliterans. On the 381st day PT, she remained clinically stable. Chest x-ray film showed mild overinflation, but was otherwise unremarkable. PFT's continued to show very severe airflow obstruction without restrictive ventilatory defect. The etiology of the obliterative bronchiolitis might be explained on the basis of a direct immunologic reaction mediated by GVHD or possibly a joint viral-GVHD interaction. Awareness and further detailed documentation and analysis of this unusual respiratory syndrome associated with marrow transplant recipients may help clarify the role of GVHD in the development of lung disease in recipients of marrow grafts.

35 patients were treated for acute myeloid leukaemia or acute lymphoblastic leukaemia with allogeneic bone-marrow grafts from a parent, child, or sibling who was mismatched at the major histocompatibility complex (MHC). 11 of these patients are alive at least 6 months after grafting, 5 of them after more than 2 years. Of the 15 patients aged under 20 at the time of the graft, 8 are alive and well 6 months to 3 years later. Cyclosporin A was given to all patients after grafting. 1 patient died of acute graft-versus-host disease and in 2 other cases this was a major factor in their death. Graft failure caused the death of 2 patients. 4 patients died of recurrent leukaemia. A fatal complication in 12 patients was pulmonary oedema, often associated with convulsions, intravascular haemolysis, and renal failure. Some of these patients had viral or bacterial infections, but in the majority the syndrome was not associated with demonstrable infection. This syndrome, in which the essential lesion appears to be vascular, was much more common in recipients of mismatched than matched grafts. 3 others died from lung disease in which infection was a factor.

Cryptogenic organizing pneumonia (COP), also known as bronchiolitis obliterans organizing pneumonia (BOOP), is an uncommon lung disease characterized by the presence of granulation tissue within the alveolar ducts and alveoli. Because of the limited published literature on this topic and limited information on outcome we reviewed our own experience over an 8-year period and also critically evaluated the literature. We reviewed all cases of COP diagnosed from 1985 through 1992 at Vancouver General Hospital: 25 patients (14 male, 11 female) aged 20-77 years (mean, 49 yr, SD +/- 17 yr). Nine patients had myeloproliferative disorder, including 6 who had allogenic bone marrow transplants; 2 patients had connective tissue disease; and 14 patients had no underlying disease (idiopathic). Data retrieved retrospectively from clinical records included demographics, risk factors, symptoms, chest radiographs, computerized tomograms, lung function tests, therapy prescribed, and response to therapy. Symptoms included dyspnea and cough (n = 15) (60%), cough only (n = 10) (40%), and fever (n = 15) (60%). Twenty-two patients were diagnosed by open lung biopsy and 3 by transbronchial biopsy. Lung imaging showed bilateral patchy airspace consolidation or nodular opacities as the main finding in 22 patients. Pulmonary function tests showed a combined restrictive and obstructive pattern. All patients received prednisone therapy except 1 patient whose idiopathic findings resolved completely with minimal treatment. Eight patients died, including 4 of the 9 patients with myeloproliferative disorder--2 from a combination of respiratory failure due to COP and graft-versus-host disease. One of 2 patients with connective tissue disease died, and 3 of 14 patients with idiopathic COP died. COP is an uncommon condition but should be considered in patients with bilateral airspace disease, especially those who fail to respond to antibiotics for presumed pneumonia. Although pulmonary function tests and CT scan findings in conjunction with the clinical features usually suggest the diagnosis, definite confirmation usually requires either open lung biopsy or transbronchial biopsy. Histologic confirmation of the diagnosis is particularly warranted as therapy with corticosteroids is usually needed for a number of months. The prognosis is excellent with idiopathic cases but more guarded especially when COP is associated with lymphoproliferative or connective tissue disease.

Patients at a single pulmonary centre who developed obstructive lung disease after bone marrow transplantation (BMT) and lung transplantation (LT) were studied, in order to compare the clinical expression of post-transplant obstructive lung disease (PTOLD) (bronchiolitis obliterans) in these two conditions, which have so far been studied separately. Nine out of 179 patients surviving more than 100 days after BMT (5%) and 9 out of 44 patients surviving more than 100 days after LT (20%) developed post-transplant obstructive lung disease. This was defined by an irreversible airflow obstruction, as characterized by a forced expiratory volume in one second divided by forced vital capacity (FEV1/FVC) of less than 70%, and a FEV1 of less than 70% of predicted value. The mean interval between transplantation and the diagnosis of post-transplant obstructive lung disease was 262 days and 217 days for BMT and LT patients, respectively. In all cases, pulmonary symptoms consisted of dyspnoea and progressively productive cough. Bronchial dilatation on high-resolution computed tomography scans was the main imaging feature present in both groups of patients at the onset of post-transplant obstructive lung disease. The mean FEV1/FVC ratio was 51 and 54% for BMT and LT patients, respectively. All BMT and LT patients had normal transfer coefficient. Clinical chronic graft-versus-host disease was present in all BMT patients before or concurrent with the onset of post-transplant obstructive lung disease, and all LT patients had presented at least one episode of acute lung rejection.(ABSTRACT TRUNCATED AT 250 WORDS)
