Abstract
One hundred and four patients with Hodgkin's disease have been studied retrospectively in order to evaluate the relationship between fever associated with the disease (Pel-Ebstein type) and the development of anaemia. In the material 19 episodes of fever were found to be of this type. The mean loss of Hb during a fever period was 14% (range 2-33). From the rate of decrease in Hb it was deduced that this was at least partly caused by an increased destruction of erythrocytes. There was a significant correlation between the thermal exposure (expressed either as the duration of fever, the maximum body temperature during the fever period, or the sum of the temperature maxima) and the degree of erythrocyte loss. The loss of Hb was self-limited in spite of persistent fever. Furthermore, there seemed to be an inverse relationship between the degree of preexisting anaemia and the fever-induced relative loss of Hb. A possible explanation is that the older part of the erythrocyte population is more sensitive to the effect of fever.
