[Evaluation on the clinical background on early death in patients with pulmonary tuberculosis during the past five...

We evaluated the clinical background of early death (within 3 months after admission to our hospital) in patients with active pulmonary tuberculosis during the past five years (1992-1996). Among 65 active pulmonary tuberculosis patients who died during the past five years, 32 (49%) died directly of tuberculosis. Thirteen (41%) of those 32 patients died of acute respiratory failure and 9 patients (28%) died in emacitation state. Twenty two patients (69%) died within 3 months after admission to our hospital (the early death group) and 10 patients (31%) died after 3 months (the late death group). Thirteen patients (59%) in the early death group died of acute respiratory failure. On the other hand, none in the late death group died of acute respiratory failure but 4 patients died of chronic heart and/or respiratory failure and 4 patients died in emarciation state. Compared to the patients in the late death group, more patients in the early death group had long total delays (patient's and doctor's delays), had coexisiting diseases, had fallen into acute respiratory failure, and were under malnutrition. We evaluated the nutritional condition of patients using the Onodera's PNI (Prognostic Nutritional Index; 10 x serum almumin concentration + 0.005 x peripheral lymphocyte count) and the PNI value was lower among the patients in the early death group than among those in the late death group. To prevent death due to tuberculosis, we emphasize that it is important to start anti-tuberculosis therapy before patients fall into acute respiratory failure and/or malnutrition.
