Two patients receiving oral etoposide therapy developed Pneumocystis jirovecii pneumonia during chemotherapy with significant lymphopenia without corticosteroid use. In this commentary we discuss cellular mechanisms by which etoposide induced CD4+ T lymphocyte dysfunction and reduced survival may lead to predisposition to P. jirovecii infection.
- malignant disease and immunosuppression
- haematology (incl blood transfusion)
- pneumonia (infectious disease)
