Abstract:
BACKGROUND: Physicians find fever of unknown origin (FUO) a difficult problem to solve. Analysis of the causes of FUO may be useful in the diagnosis of FUO. We investigated the causes of FUO in the last two decades from 1980 to 1999 and compared the two decades to seek for a trend of changes of the causes of FUO. METHODS: Among 854 patients diagnosed as FUO on discharge, we retrospectively reviewed 278 patients compatible with the Petersdorf's criteria through inpatient and outpatient medical records. RESULTS: There were 144 (51.5%) men and 134 (48.2%) women. Among the 98 patients in the 1980s, infectious disease was the cause in 37 (37.8%) patients, collagen vascular disease in 17 (17.3%), malignancy in 8 (8.2%), miscellaneous in 11 (11.2%), and unidentifiable cause in 25 (25.5%) patients. Among the 180 patients in the 1990s, infectious disease was the cause in 45 (25.0%) patients, collagen vascular disease in 37 (20.5%), malignancy in 34 (18.9%), miscellaneous in 45 (25.0%), and unidentifiable cause in 19 (10.6%) patients. According to the order of frequency, the causes of infectious disease were pulmonary tuberculosis (19.4%), extrapulmonary tuberculosis (8.2%), liver abscess (4.1%) in the 1980s and extrapulmonary tuberculosis (17.2%), pulmonary tuberculosis (4.4%), liver abscess (1.1%) in the 1990s. The diagnostic methods for evaluation of FUO were culture (45.6%), radiology (17.6%), serology (16.2%), and biopsy (10.3%) in the 1980s and radiology (31.5%), biopsy (26.9%), culture (21.5%) and serology (20.0%) in the 1990s. CONCLUSION: Among the causes of FUO, infectious disease decreased and collagen disease and malignancy increased with time. The most common cause of infectious disease was pulmonary tuberculosis in the 1980s but extrapulmonary tuberculosis in the 1990s. Use of radiology and biopsy as diagnostic methods for FUO increased.
