    Abstract:
    The patients with active tuberculosis in whom respiratory failure requiring mechanical ventilation developed were studied retrospectively. Nine patients (M 8, F 1) were identified at the National Tokyo Hospital during 5 years from January, 1993 to December, 1997. Seven of 9 patients were single men, and the duration of symptoms before admission was over 1 month in all patients, while the time from first visit to diagnosis was less than 7 days. All patients were identified as malnourished, and 7 patients suffered from another underlying diseases. The patients were classified into two groups. Six of 9 patients had pulmonary tuberculosis and the other three had miliary disease. The proportion of cases requiring mechanical ventilation was 0.3% and 8.6%, respectively, in pulmonary tuberculosis and miliary tuberculosis. At the start of mechanical ventilation, PaO2/FIO2 was lower than 200 in all 9 patients, and 6 patients were probably ARDS. Steroids (methylprednisolone 250-1000 mg/day) were used in all 9 patients. Despite the use of mechanical ventilation and antituberculous therapy, 8 out of 9 patients died. Only one patient with miliary tuberculosis survived. The establishment of the therapy for acute respiratory failure is needed so as to improve prognosis of such cases. At the same time, the delay in consulting a doctor led to acute respiratory failure in most cases, so it is also important to encourage tuberculosis patients to visit a doctor as soon as possible, after the appearance of symptoms.
