Bronchiolitis obliterans complicating bone marrow transplantation.

چکیده
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.

Azithromycin in bronchiolitis obliterans complicating bone marrow transplantation: a preliminary study.
Bronchiolitis obliterans (BO) is a serious noninfectious pulmonary complication following allogeneic bone marrow transplantation (BMT). Azithromycin, a macrolide antibiotic, may have a beneficial effect in BO through its anti-inflammatory effect. The aim of the current study was to investigate the potential effect of azithromycin on pulmonary function tests (PFTs) in BO complicating BMT. PFTs o...
متن کامل[A lung transplant in a woman with bronchiolitis obliterans following an allogenic bone marrow transplant].
Graft-versus-host disease is a major complication for bone marrow transplant recipients and is often a cause of late mortality. It can affect any tissue, and involvement of the lungs--target organs of particular importance--can lead to chronic respiratory failure due to bronchiolitis obliterans. We report the case of a lung transplant in a woman who developed bronchiolitis obliterans after rece...

Pneumothorax is very rare after early phase of hematopoietic stem cell transplantation (HSCT) and usually accompanied with pulmonary chronic graft-versus-host disease (GVHD), such as bronchiolitis obliterans and bronchiolitis obliterans organizing pneumonia. The present study describes the case of a seventeen-year-old male diagnosed with acute myeloid leukemia who underwent allogeneic bone marr...

We report a successful case of living-donor lobar lung transplantation (LDLLT) for therapy-resistant broncho-bronchiolitis obliterans (BBO) after allogeneic hematopoietic stem cell transplantation (HSCT). Bronchiolitis obliterans (BO) is one of the late-onset noninfectious pulmonary complications that occur after allogeneic HSCT and is usually resistant to immunosuppressive therapy. A 17-year-o...
