Abstract

The objective of the study was to compare disease characteristics over the first 5 years of disease in patients with RA, with disease onset in 1990s and 2000s, respectively.

Methods :

All 2235 patients with early RA (disease duration ≤12 months) were recruited from the BARFOT prospective observational study. These patients were divided into group 1 included 1992 to 1999 (N=1084, 66% women) and group 2 included 2000 to 2006 (N=1151, 69% women). Disease Activity Score (DAS28), VAS pain and Health Assessment Questionnaire (HAQ) were assessed during 5 years. Remission was defined as DAS28 <2.6.

Results :

At inclusion, both women and men in group 2 had higher mean DAS28 (SD) than group 1, 5.42 (1.22) vs 5.26 (1.19), p=0.004 and 5.28 (1.22) vs 5.00 (1.27), p=0.004, respectively, mainly dependant on pain and not on inflammatory related measures. Over time DAS28 decreased and was in both genders, from 6 months to the 5-year follow-up, significantly lower in group 2. At 5-year, both women and men in group 2 had higher rate of remission than women and men in group 1. However, despite reduction of VAS pain and HAQ there were no differences in pain and HAQ between groups at any time point.

Conclusion :

Patients included in the 2000s achieved higher frequency of remission at the 5 year follow-up compared with those included in the 1990s, suggested to reflect the more active medical treatment. Interestingly, however, improvement in pain and HAQ did not differ between the two patient cohorts.

"It is important that students and researchers from all over the world can have easy access to relevant, high-standard and timely scientific information. This is exactly what Open Access Journals provide and this is the reason why I support this endeavor."


Jacques Descotes
(Centre Antipoison-Centre de Pharmacovigilance, France)

"Publishing research articles is the key for future scientific progress. Open Access publishing is therefore of utmost importance for wider dissemination of information, and will help serving the best interest of the scientific community."


Patrice Talaga
(UCB S.A., Belgium)

"Open access journals are a novel concept in the medical literature. They offer accessible information to a wide variety of individuals, including physicians, medical students, clinical investigators, and the general public. They are an outstanding source of medical and scientific information."


Jeffrey M. Weinberg
(St. Luke's-Roosevelt Hospital Center, USA)

"Open access journals are extremely useful for graduate students, investigators and all other interested persons to read important scientific articles and subscribe scientific journals. Indeed, the research articles span a wide range of area and of high quality. This is specially a must for researchers belonging to institutions with limited library facility and funding to subscribe scientific journals."


Debomoy K. Lahiri
(Indiana University School of Medicine, USA)

"Open access journals represent a major break-through in publishing. They provide easy access to the latest research on a wide variety of issues. Relevant and timely articles are made available in a fraction of the time taken by more conventional publishers. Articles are of uniformly high quality and written by the world's leading authorities."


Robert Looney
(Naval Postgraduate School, USA)

"Open access journals have transformed the way scientific data is published and disseminated: particularly, whilst ensuring a high quality standard and transparency in the editorial process, they have increased the access to the scientific literature by those researchers that have limited library support or that are working on small budgets."


Richard Reithinger
