title: Clinical spectrum of fever of unknown origin among adult Egyptian patients admitted to Ain Shams University Hospitals: a hospital based study.
abstract: This prospective study was designed to analyze the clinical spectrum of fever of unknown origin (FUO) among adult Egyptian patients admitted to Ain Shams University Hospitals during the period from May 2009 till the end of December 2010. All Egyptian patients fulfilling the criteria of FUO admitted during this period were followed up till reaching the diagnosis. 93 patients were included in the study. They were 48 (51.6%) females and 45 (48.4%) males, their ages ranged from 15 to 65 years (34.39 +/- 13.6). Infections were the commonest cause of FUO (41.94%) followed by malignancies (30.11%). While autoimmune diseases represented 15.05% and in 12.9% of patients the diagnosis was not established. Brucellosis and infective endocarditis were the commonest infections, while hematological malignancies were the commonest oncological diseases. Systemic lupus erythematosus (SLE) was the commonest auto-immune disease. Brucellosis, infective endocarditis, hematological malignancies and SLE must be considered in the differential diagnosis of adult FUO in Egypt.
