A 12-year-old girl with Sly disease (mucopolysaccharidosis VII; beta-glucuronidase deficiency), who is homozygous for the A619V mutation, had a successful allogeneic BMT, donored by an HLA-identical unrelated female to replace the deficient enzyme. Within 5 months after BMT, the enzyme activity of the recipient's lymphocytes increased to normal range. No signs of acute or chronic GVHD were observed. For the successive 31 months post-BMT, beta-glucuronidase activity in her lymphocytes was maintained at almost normal levels and excretion of glycosaminoglycans in the urine was greatly diminished. Ultrastructural findings demonstrated no abnormal vacuoles and inclusion bodies in the cytoplasm of her rectal mucosal cells. Coincident with the restoration of the enzyme activity, clinical improvement was dramatic. Especially notable were improvements in motor function. The patient was able to walk alone for a long time without aid, and she even became able to ride a bicycle and take a bath. In addition, recurrent infections of the upper respiratory tract and the middle ears decreased in frequency and severity, and dyspnea on exertion, severe snoring and vertigo have substantially improved. Thus, allogeneic BMT in this patient produced a better quality of life and provided a more promising outlook.

A 16-year-old boy developed bronchiolitis obliterans (BO) 10 years after BMT for myelodysplastic syndrome. Although the patient complained of almost no dyspnea on exertion, he had mild hypercapnea with a markedly reduced forced expiratory volume of 0.32 l. Chest X-rays showed occasional bilateral minimal pneumothoraces, which is in accordance with the existence of multiple small bullae found on the pleural surface at video-assisted thoracic surgery. Histologic examination of the biopsied lung revealed BO. This case indicates that BO in adolescence following BMT and possible chronic GVHD may be masked because of lung immaturity at BMT, and BO after BMT may be associated with multiple pleural bullae.

A 45-year-old man was diagnosed as having Ph1+ acute lymphocytic leukemia (ALL) in February 1997. Complete remission was achieved by chemotherapy. Allogeneic BMT from his HLA-identical sister was performed on June 11, 1997. Engraftment was relatively quick, but acute GVHD (grade I) developed. The patient was discharged on day 113. Seven months after BMT, in January 1998, exertional dyspnea developed gradually. Chest X-ray examination showed diffuse interstitial pneumonia, for which corticosteroid was started immediately. The symptoms and signs gradually improved. However, on the 20th hospital day (February 23), bilateral subcutaneous emphysema developed in the neck and supraclavicular region. Chest X-ray and CT examinations showed pneumomediastinum without pneumothorax. The pneumomediastinum and subcutaneous emphysema gradually subsided after 3 weeks of bed rest. Subcutaneous emphysema and pneumomediastinum are relatively rare complications of allogeneic BMT.
