[Analysis of the state of patients with rheumatoid arthritis using a personal computer]

The present study was designed to analyze the state of 203 patients with rheumatoid arthritis (RA) in our clinic using a personal computer. The duration of the disease was significantly correlated with the progression of radiographical stages of RA, indicating that no drugs were able to prevent the progression of joint destruction. Nevertheless, bucillamine, a newly developed anti-rheumatic drug, was found to be effective in some patients who did not respond to D-penicillamine, but not vice versa. Although seropositive RA patients had more severe disease than seronegative RA patients, serum rheumatoid factor levels were not significantly correlated with Lansbury indices in seropositive RA patients. Overall, either the liver function or the renal function was not significantly affected in any category of the patients. Taken together, it is suggested that analysis of the data of the RA patients with personal computer systems provide useful information on the management of the RA patients.
