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.[1]
Neutropenic FUO
These are mostly caused by bacterial, fungal and viral infection because of the decreased neutrophil count.[2]
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.[3]
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.[4]
