Cyclic AMP and cyclic GMP are important regulatory agents of lymphocyte functions. Depressed T-lymphocyte functions are frequently associated with Hodgkin's disease and suppressor monocytes have been implicated in the pathogenesis of this defect. In the present study cAMP and cGMP resting levels were measured in lymphocytes from 18 untreated patients with Hodgkin's disease using a sensitive radioimmunoassay. A significant decrease of cAMP (P less than 0.001) and, to a lesser degree, of cGMP (P less than 0.01) was found in monocyte-depleted lymphocyte suspensions from the patients compared to controls. Studies of patient and control lymphocyte subpopulations showed in patients a clear deficit of cAMP in T-depleted lymphocytes, rather than in T cells, with a low cAMP/cGMP molar ratio in both subpopulations. From this data it is clear that factors other than prostaglandin-mediated suppression of monocyte origin are involved in the pathogenesis of the T-lymphocyte depression associated with Hodgkin's disease.
