Description
The clinical records of 93 cases with Staphylococcus aureus (S. aureus) bacteremia of the aged at Tokyo Metropolitan Geriatric Hospital from 1973 through 1984 were reviewed. In this period, the incidence of S. aureus bacteremia was 11% of all bacteremia. Eight cases were monomicrobial and 13 cases were polymicrobial bacteremia.<BR>Patients with malignancy were observed 37.6% and cerebrovascular disease were observed 20.4% of all cases. The most common portal of entry were the urinary tract in 21 cases and indwelling intravenous catheter related in 17 cases. The mean days of the indwelling intravenous catheter at the inguinal region prior to the detection of S. aureus bacteremia was 6 days and were shorter than other sites. Twenty two out of 80 cases of monomicrobial bacteremia developed shock.<BR>Total mortality of the bacteremia which was defined as death within one month at the onset of the bacteremia was 47.3%. A high mortality, 60.0%, was observed in patients with respiratory tract as the portal of entry. The factors which contribute to poor prognosis were malignancy, DIC and shock. And thier mortality were 68.6%, 88.9% and 86.7%, respectively. While, the mortality of the patients without malignancy or DIC, shock were about 16%. There was no significant difference in the mortality between methicillin resistant S. aureus (MIC≥25μg/ml) and methicillin sensitive S. aureus bacteremia.
