    Abstract:
    OBJECTIVE: Clinical remission is now a realistic goal in managing RA following the introduction of biologic agents. As there are limited data on sustained remission in conventionally treated RA, this study examines prevalence and predictive factors of sustained remission in a pre-biologic inception cohort of RA. METHODS: Patients with recent onset RA and before use of DMARDs were recruited from nine centres. Standard clinical and radiological assessments were recorded at baseline and yearly. Point remission was defined by DAS of <1.6, and sustained remission if DAS was <1.6 at all 3-, 4- and 5-year follow-ups. Sustained remission was compared with baseline features, with mortality and with radiological and functional progression in 704 patients. RESULTS: Point remission at 3, 4 and 5 years was 25, 26 and 22%, respectively. Eleven per cent (n = 78) had sustained remission. Male sex, short duration of symptoms and less tender joints at baseline were independent predictors of sustained remission. These patients had fewer DMARD therapies and less radiographic progression by 5 years. Mean HAQ decreased from 0.79 to 0.13 (P < 0.001) in sustained remission, compared with an increase from 0.92 to 1.1 (P < 0.001) in the non-remission group. CONCLUSION: Sustained clinical remission by 5 years with conventional DMARDs was 11%, half as likely as point remission. Prognostic factors were similar to comparable studies and simple to measure. Patients in sustained clinical remission showed less structural damage and better functional outcomes.
