title: Fever of unknown origin: a report from China of 208 cases.
abstract: Fever of unknown origin (FUO) is a clinical dilemma in western countries and in China. To investigate the causes and prognosis of FUO, 208 patients with FUO admitted to a large university hospital in China were investigated. The final diagnoses established in 158 cases (75.96%) were: infectious disease in 66 cases (31.73%), collagen vascular disease in 46 patients (22.11%), neoplasm in 35 cases (16.83%), and other disease in 11 patients (5.29%). In 66 cases with infectious disease, tuberculosis, septicaemia and typhoid fever were the principal causes. SLE and adult Still's disease were the most important causes among collagen vascular disease. Lymphoma and malignant histiocytosis were mostly associated with FUO among neoplasms. In 50 cases (24.04%), the cause of fever was not found. On discharge from hospital, fever had subsided in 133 cases (63.94%), and had persisted in 63 cases (30.29%); 12 patients (5.87%) died. In China, infectious disease, collagen vascular disease and neoplasm are the main causes of FUO. While most patients recover, there are some differences in the distribution of causes between the West and China, and there are relatively more deaths than in previous reports.
