Overview
Classic FUO may be caused by infection, neoplasia, inflammatory , miscellaneous diseases, and undiagnosed illness.Common causes of neutropenic FUO include bacterial, fungal and viral infection.Causes of nosocomial FUO are related to hospital setting such as drugs, infections acquired during hospitalization and complications that occur during and after surgery.This may due to acute infection from HIV itself earlier or later due to opportunistic bacterial, fungal and viral infections such as mycobacteria, toxoplasma etc.
Causes
Etiology is different for different categories of FUO:
Classic FUO
- Malignancies such as Hodgkin and non-Hodgkin lymphoma, myeloproliferative disorders, colorectal carcinoma and carcinoma of liver.
- Infections such as intrabdominal and pelvic abscesses, inflammation of the endocardium, tuberculosis, cat scratch disease, CMV and EBV infections.
- Inflammatory causes such as autoimmune diseases (systemic lupus erythematosus, Rheumatoid arthritis) and polymyalgia rheumatica.[1]
- Miscellaneous such as Medication/drug fever,Hyperthyroidism Hematoma,Chronic pulmonary.[2]
Neutropenic FUO
These are mostly caused by bacterial, fungal and viral infection because of the decreased neutrophil count.[3]
HIV associated FUO
This may due to acute infection from HIV itself earlier or later due to opportunistic bacterial, fungal and viral infections such as mycobacteria, toxoplasma etc.[4]
Nosocomial FUO
Causes of nosocomial FUO are related to hospital setting such as drugs, infections acquired during hospitalization and complications that occur during and after surgery.[2]
