Pel-Ebstein fever
Pel-Ebstein fever, also known as Ebstein-Cardarelli fever, is a rarely seen condition noted in patients with Hodgkin's lymphoma in which the patient experiences fevers which cyclically increase then decrease over an average period of one or two weeks. A cyclic fever may also be associated with other conditions, but it is not called "Pel-Ebstein fever" unless the fever is associated with Hodgkin's.
Causes
The cause is currently unknown although speculation centers on host immune response - particularly the cyclical release of cytokines, lymph node necrosis, and damaged stromal cells.
Treatment
Treatment with non-steroidal anti-inflammatory agents or treatment of the underlying Hodgkin's (usually with chemotherapy) will help the symptoms.
Eponym
The condition is named after Wilhelm Ebstein and P.K. Pel who both published papers in 1887 noting the phenomenon. Both doctors published in the same journal, though Pel published first by several months. Interestingly, a long-term dispute persisted between Pel and Ebstein on the etiology of the condition.
