“…Patients in whom the risk of PJP is not conclusively established, but is likely to be moderate, include those with autologous bone marrow transplant, and patients with haematological malignancy undergoing certain high‐intensity chemotherapy regimens. In the latter case, clinicians should be particularly vigilant of R‐CHOP14 (rituximab, cyclophosphamide, adriamycin, vincristine, prednisolone chemotherapy on a 14‐day cycle), FCR (fludarabine, cyclophosphamide, rituximab), AVBD (adriamycin, vincristine, bleomycin, dexamethasone), gemcitabine and high‐dose methotrexate. Patients with prolonged CD4 lymphopenia, before or after initiation of chemotherapy, are also likely to be at moderate risk of PJP.…”
