BACKGROUND The treatment of rheumatoid arthritis should aim at clinical remission. This multicentre, randomised trial with 2-year follow-up sought evidence on the efficacy and tolerability of combination therapy (sulphasalazine, methotrexate, hydroxychloroquine, and prednisolone) compared with treatment with a single disease-modifying antirheumatic drug,(More)
Patients with rheumatoid arthritis (RA), 500 men and 500 women, aged 40 years and over, together with a control population matched by age and sex were followed up with respect to cause-specific mortality over a 10-year period. The overall mortality was significantly higher in both men and women with RA than in the controls. A statistically significant(More)
Five hundred men and 500 women, aged 40 or over, with rheumatoid arthritis, together with a control population matched for age and sex, were observed over 10 years. During that time 352 patients with rheumatoid arthritis (208 men, 144 women) and 221 controls (148 men, 73 women) died. The overall mortality was significantly higher (p less than 0.0001) in(More)
Patients with rheumatoid arthritis (RA), 500 men and 500 women, aged 40 years and over, together with a control population matched by age and sex, were observed over a 10 year period. The overall mortality was significantly higher in both men and women with rheumatoid arthritis than in the controls due to an excess mortality from infections and(More)
Among 3115 autopsied patients, rheumatoid arthritis was registered in 41 patients (1.3%). The causes of death of these were correlated with the causes of death of 310 non-rheumatoid autopsied patients. Of the RA patients, 32% died from cardiovascular disease, 24% from infection, 27% from renal failure and 7% from malignant disease. Of the control patients,(More)
Patients with rheumatoid arthritis, 500 males and 500 females, aged 40 years or over, together with an age and sex matched control population, were observed over a 5-year period. During the follow-up 176 RA patients and 107 controls died. The most common causes of death in RA patients were cardiovascular diseases (86 patients), renal failure (33 patients),(More)
Patients with rheumatoid arthritis (RA), 500 males and 500 females, aged 40 years and over, together with an age and sex matched control population, were observed over a 10-year period. The overall mortality was significantly higher in both men and women with RA than in the controls. During the followup, 42 patients with RA (28 males, 14 females) and 58(More)
Patients with rheumatoid arthritis, 500 males and 500 females, aged 40 years or over, and an age- and sex-matched control population were observed over a 3-year period. During the follow-up, 122 RA patients and 69 controls had died. The most common causes of death in RA patients were cardiovascular diseases (57 patients), renal failure (27 patients),(More)
Cellular inflammation in rheumatoid arthritis (RA) synovial membrane was studied in biopsy specimens taken at different stages of synovitis and disease. Patients were classified into three subgroups: acute RA, subacute RA, and chronic RA. Inflammatory cells were characterised by a histochemical esterase method and immunohistochemical(More)
The subtype of the proliferating cells in the synovial fluid of patients with rheumatoid arthritis (RA), ankylopoietic spondylarthrosis (SPA), and osteoarthritis (OA) was studied with autoradiography-immunoperoxidase double staining. Of all spontaneously proliferating synovial fluid cells in chronic arthritis, 59 +/- 4% displayed T8 differentiation marker,(More)
