The immunoglobulins in Hodgkin's disease

Immunoglobulins have been measured in fifty patients with Hodgkin's disease. Levels of γG were slightly raised as compared with a control population, but γA tended to be low and γM was generally at or below our lower limit of normal. These findings are discussed in relation to the duration of the disease, its clinical staging, and the possible effects of radiotherapy and chemotherapy.

It is suggested that the reduced γM levels are due to decreased synthesis in the reticulo-endothelial system rather than to increased catabolism. Reference is made to the depression in delayed-type hypersensitivity found early in Hodgkin's disease and this and reduction in γM levels may both reflect the same derangement in lymphoid cells.

The detection of α₃-globulin in the sera of 62 per cent of the patients is referred to and its association with other neoplastic reticuloses is emphasized.
