Background: To investigate whether intensive treatment with methotrexate (MTX) according to a strict protocol and a computerised decision program is more beneficial compared to conventional treatment with MTX in early rheumatoid arthritis. Methods: In a two-year multicentre open label strategy trial, 299 patients with early rheumatoid arthritis were randomly assigned to the intensive strategy group or the conventional strategy group. Patients in both groups received MTX, the aim of treatment being remission. Patients in the intensive treatment group came to the outpatient clinic once every month; adjustment of the MTX dosage was tailored to the individual patient on the basis of predefined response criteria, using a computerised decision program. Patients of the conventional strategy group came to the outpatient clinic once every three months; they were treated according to common practice. Cyclosporine was added if patients had an inadequate response to maximal tolerated MTX doses. Results: Seventy six (50%) patients in the intensive strategy group achieved at least one period of remission during the two year trial, versus 55 patients (37%) in the conventional strategy group (p = 0.03). Areas under the curve for nearly all clinical variables were significantly lower-that is, there was a better clinical effect for the intensive treatment group compared with the conventional treatment group. Conclusion: The results of this study show that it is possible to substantially enhance the clinical efficacy early in the course of the disease by intensifying treatment with MTX, aiming for remission, tailored to the individual patient. Furthermore, participating rheumatologists indicated that the computerised decision program could be a helpful tool in their daily clinical practice.

To evaluate the predictive power of changes in levels of antibodies to double-stranded DNA (antidsDNA) as a predictor of disease exacerbations in systemic lupus erythematosus (SLE), we performed a prospective study on 72 unselected patients with SLE (mean duration of study 18.5 months, range 6-35 months). Patients were seen at least once every 3 months, and disease activity was scored according to a specific protocol. Plasma samples were obtained at least once every month and were assessed for anti-dsDNA antibody (by the Crifhidiu luciliue assay, an enzymelinked immunosorbent assay [ELISA], and the Farr assay) and for complement components C3 and C4. Twenty-seven of 33 disease exacerbations observed during the study period were accompanied by a positive test result for anti-dsDNA antibody (27 by the Farr assay, 19 by the C luciliae assay, and 23 by the ELISA). Twentyfour of these exacerbations were preceded by a significant increase in anti-dsDNA antibody levels (23 by the Farr assay, 12 by the C luciliae assay, and 17 by the ELISA). The first observance of a significant increase in anti-dsDNA antibody levels preceded the exacerbation by 8-10 weeks. Significant increases in anti-dsDNA antibody levels not followed by an exacerbation were observed in 5 cases by the Farr assay, in 7 cases by the C luciliue assay, and in 3 cases by the ELISA; however, in 3 cases, 2 cases, and 1 case, respectively, these increases were followed by an increase in disease activity that did not fulfill the criteria for an exacerbation. Serial measurement of anti-dsDNA antibody levels was more sensitive for predicting exacerbations than was measurement of C3 andor C4 levels (P < 0.03). Serial assessment of anti-dsDNA antibody levels, especially by the Farr assay, is a sensitive and reasonably specific method for predicting disease exacerbations in SLE.Systemic lupus erythematosus (SLE) is characterized by protean clinical manifestations and the occurrence of a variety of autoantibodies. Among these, anti-double-stranded DNA (anti-dsDNA) antibodies are highly specific for SLE and are detected at a high frequency (75-

Early introduction of SAARDs may be more beneficial than delayed introduction for patients with recently diagnosed rheumatoid arthritis.
