  1. Possible etiologies of FUO • Infections • Localized pyogenic (ex. Appendicitis, Liver abcess) • Intravascular infection (ex. Bacterial endocarditis) • Systemic (ex. Leptospirosis) • Mycobacterial (ex. Tuberculosis) • Other bacterial (ex. Actinomycosis) • Rickettsial (ex. Anaplasmosis) • Mycoplasmal infections • Chlamydial infections (ex. Lymphogranuloma venereum) • Viral infections (ex. HIV) • Fungal infections (ex. Candidiasis, Pneumocystis) • Parasitic infection (ex. Amoebiasis) • Presumed infections agent undetermined (ex. Kawasaki’s Disease)

  2. Possible etiologies of FUO • Neoplasms • Malignant (ex. Colon cancer) • Benign (ex. Renal angiomyolipoma) • Habitual Hyperthermia • Collagen vascular/ hypersensitivity disease • Ex. Adult Still’s Disease • Granulomatous diseases • Ex. Crohn’s disease • Miscellaneous • Ex. Drug Fever

  3. Possible etiologies of FUO • Inherited and Metabolic Diseases • Ex. Cyclic neutropenia • Thermoregulatory disorders • Central (ex. Brain tumor) • Peripheral (ex. Hyperthyroidism) • Factitious fevers

  4. Possible etiologies for the present case • Drug fever • patient has been taking cardiovascular drugs such as Atenolol and unrecalled antibiotics (may be B-lactam) • Infection • previous travel history may indicate malaria • Patient also has a history of hepatitis A infection, signs such as icteric sclerae • Neoplasm (probably in the GI tract) • Signs and symptoms such as RUQ pain, weight loss, malaise, pale colored stool, icteric sclerae • Patient is >50 years old and is predisposed to have colon cancer

  7. FUO etiology (child vs. adult) CHILD ADULT Infection Neopastic d/o Drug fever Collagen vascular/ hypersensitivity diseases Factitious fever Principal cause: Rheumatological diseases and infections In elderly, most frequent cause is Multi-system disease such as: Infection- TB Malignancy- colon cancer
