ABSTRACT
The target cellular response to glucocorticoids is proportional to the concentration or affinity of specific receptors to these substances. To look for a correlation between glucocorticoid receptors concentrations in synovial wall cells and the clinical response to steroidal treatment in patients with rheumatoid arthritis. Twenty eight patients with rheumatoid arthritis were studied. Each subject was subjected to a synovial biopsy in which a dry radioautographic technique for diffusable compounds was used. Patients were treated afterwards with 3 500mg iv pulses of methilprednisolone. A mean of 44.8 percent of synovial cells (range 30.1-62.8 percent) had binding sites for 3H dexamethasone. All patients had a significant clinical improvement after methilprednisolone. Multiple regression analysis did not show a correlation between clinical response and glucocorticoid receptor concentration. The lack of association between glucocorticoid receptor concentration and clinical response could be due to the large steroid dose used, that saturated all available receptors
