Case Reports
Treatment of bronchorrhea by corticosteroids in a case of bronchioloalveolar carcinoma producing CA19-9.
A case of gastrointestinal cancer-associated antigen (CA19-9)-positive bronchioloalveolar carcinoma accompanied by bronchorrhea and respiratory failure successfully treated with corticosteroids is reported. The patient was treated with pulse methylprednisolone at a dose of 1,000 mg/day for three days, followed by oral prednisolone (60 mg/day). ⋯ The levels of CA19-9 in the serum and the sputum were extremely high and an immunocytochemical study showed that the tumor cells were stained by CA19-9 antibody. This case demonstrates the therapeutic value of corticosteroids in the treatment of bronchorrhea in subjects with bronchioloalveolar carcinoma.

There is clinical and pathological evidence of thrombosis in pulmonary vessels of patients with chronic obstructive pulmonary disease (COPD). The purpose of this study was to investigate the presence of hypercoagulability and determine the extent of this abnormality in COPD patients. ⋯ Our results showed an enhanced prothrombotic process in COPD patients, which could potentially account for the increased thrombosis in pulmonary vessels in these patients.
