Causes
Etiology is different for different categories of FUO:
Classic FUO
- Malignancies such as Hodgkin and non-Hodgkin lymphoma, myeloproliferative disorders, malignancy of colon and 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.
Neutropenic FUO
These are mostly caused by bacterial, fungal and viral infection because of the decreased neutrophil count.
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.
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.
