[Cyclic AMP level in T- and B lymphocytes in patients with rheumatoid arthritis and systemic lupus erythematosus].

The content of cAMP in blood T and B lymphocytes was measured in 30 patients with rheumatoid arthritis (RA), 10 patients with systemic lupus erythematosus (SLE) and 28 donors. A statistically significant increase in the cAMP content in T lymphocytes of RA and SLE patients was established. On the contrary, in B lymphocytes of blood of RA patients and of SLE patients, in particular, the cAMP content was below normal. In female patients with RA, the cAMP content in T lymphocytes was appreciably higher than in male patients.
