- Objective-To compare four different inception cohorts of patients with early rheumatoid arthritis (RA) with respect to treatment strategies, disease activity, and outcome during a five year follow up period. Method-Data from cohorts of patients with early RA, with a standardised assessment at least every six months for five years from four different centres, were included in one database. Owing to slight differences in the individual study designs, linearly interpolated values were calculated to complete the standard follow up schedule. Results-Despite similar inclusion criteria, significant differences in demographic factors and baseline disease activity were found between the different cohorts. During the follow up an aggressive treatment strategy was followed in the Dutch and Finnish cohort, an intermediate strategy in the British cohort, and a conservative strategy in the Swedish cohort. A significant improvement in disease activity was seen in all cohorts, though the most rapid and striking improvement was seen in those receiving aggressive treatment. This resulted in less radiographic destruction in the long run. Conclusion-This observational study of cohorts of patients with early RA confirms that early aggressive treatment results not only in a more rapid reduction of disease activity but also in less radiographic progression in the long term.

- Objective: To assess function using the Signals of Functional Impairment (SOFI) instrument over 8 years, to study clinical variables associated with the change, and to study change over time of the SOFI items.Methods: In total, 1,223 patients with early rheumatoid arthritis (RA) from the Better Anti-Rheumatic Farmacotherapy (BARFOT) cohort (mean ± SD age 56.9 ± 15.4 years, 67% women) were included in the analysis. Data from baseline and from 1 and 8 years were studied. The SOFI instrument includes measures of range of motion in the hand, shoulder/arm, and lower extremity (range 0–44, best to worst). The effects of baseline variables (sociodemographic, disease activity, joint destruction, and function) on change in SOFI scores were studied by linear regression analysis.Results: During the first year, the improvement in mean ± SD SOFI scores was 2.7 ± 5.7 (P < 0.001). Worse scores in the Disease Activity Score in 28 joints and Health Assessment Questionnaire score at baseline were associated with this improvement (r2 <= 0.11). During the next 7 years, the deterioration in SOFI scores was mean ± SD 1.5 ± 4.9 (P < 0.001). Based on change scores, we found that finger flexion, pincer grip, and toe-standing were the most important items to measure, explaining 58-61% of the total SOFI score, and these items were also associated with radiographic changes at the 8-year follow-up.Conclusion: Function as assessed with SOFI scores improved during the first year in patients with early RA, but it deteriorated slowly thereafter. Impaired hand and foot function was associated with joint destruction at the 8-year follow-up. Measures of hand and foot function will complement self-reported and medical data, both in clinical work and in long-term research studies. Copyright © 2019, Emerald Publishing Limited

- Objectives. To study the course of impairment measured by signals of functional impairment (SOFI) and disability measured by health assessment questionnaire (HAQ) over 20 years in rheumatoid arthritis (RA) patients followed from diagnosis. To explore the contribution of disease activity, joint damage and comorbidity to variation of SOFI and HAQ over time. Methods. RA patients diagnosed 1985-1989 were prospectively monitored. There were 183 patients, 63 % were women, mean (SD) age was 52 (12) years. Disease activity was measured by 44-joint DAS, joint damage by Larsen score and comorbidity by Charlson Comorbidity Index. Contribution of comorbidity, DAS and joint damage on development of SOFI and HAQ was studied at 0,5,10, 15 and 20 years follow up (hierarchical regression model) and over the total study period using (longitudinal regression model). Results. SOFI progressed over 20 years while progression of HAQ levelled off after 10 years. For SOFI, DAS and joint damage contributed the most (2-28 % and 3-31%, respectively). Over 20 years, SOFI was explained by DAS (20%), joint damage (20%), age (7%) and comorbidity (4%). For HAQ, DAS contributed the most (4-24%). Over 20 years, HAQ was explained by DAS (20%), joint damage (2%), gender (7%), comorbidity (6%) and age (4%). Conclusion. Over 20 years, 51% of the variation of SOFI and 39% of the variation of HAQ could be explained by age, gender and variations in comorbidity, disease activity and joint damage. Over time, disease activity contributed significantly to both SOFI and HAQ. Joint damage contributed predominantly to SOFI. © 2014 American College of Rheumatology.

- ABSTRACT: INTRODUCTION: Change in bone mineral density (BMD) in the hand, as evaluated by digital X-ray radiogrammetry (DXR) of the II-IV metacarpal bones, has been suggested to predict future joint damage in rheumatoid arthritis (RA). This study's objective was to investigate if DXR-BMD loss early in the disease predicts development of joint damage in RA patients followed for up to 20 years. METHODS: 183 patients (115 women and 68 men) with early RA (mean disease duration 11 months) included from 1985 to 1989 were followed prospectively (the Lund early RA cohort). Clinical and functional measures were assessed yearly. Joint damage was evaluated according to the Larsen score on radiographs of hands and feet taken in years 0 to 5, 10, 15 and 20. These radiographs were digitized and BMD of the II-IV metacarpal bones was evaluated by DXR (Sectra, Linkoping. Sweden). Early DXR-BMD change rate (bone loss) per year calculated from the first 2 radiographs taken on average 9 months apart (SD 4.8) were available for 135 patients. Mean values of right and left hand were used. RESULTS: Mean early DXR-BMD loss during the first year calculated was -0.023 g/cm2 (SD 0.025). Patients with marked bone loss, i.e. early DXR-BMD loss above the median for the group, had significantly worse progression of joint damage at all examinations during the 20-year period. CONCLUSIONS: Early DXR-BMD progression rate predicted development of joint damage evaluated according to Larsen at year one and further onwards up to 20 years in this cohort of early RA patients.

- Objective: To investigate the mortality rate and possible early predictive factors of mortality after 19-23 years in a cohort of patients with rheumatoid arthritis (RA) followed prospectively from disease onset. Patients and methods: A community-based cohort of 183 patients (63% female) with RA and disease duration < 2 years was recruited 1985-1989. The patients were followed yearly from diagnosis until death or 31 December 2008. Mean age and mean duration of symptoms (range) at diagnosis were 52 (18-78) years and 11 (0-24) months, respectively. Death certificates were obtained from the Swedish Cause of Death Register and causes of death were coded by the International Classification of Diseases (ICD-10). Death rates of RA patients were compared to those of age- and sex-matched controls. Possible predictors of mortality were analysed using a Cox regression model. Results: By 31 December 2008, 69 patients (37 women and 32 men) had died. The standardized mortality ratio (SMR) was 1.23 [95% confidence interval (CI) 0.97-1.55] and p < 0.09. Older age, male sex, smoking, and the presence of cardiovascular disease (CVD) at RA diagnosis were identified as early predictors of mortality. CVD was the most common cause of death (46%), followed by malignancies (29%) and infections (13%). RA was not stated as the direct cause of death in any patient and was mentioned among underlying causes in only 16/69 (23%) patients. Conclusion: Mortality rate after 19-23 years of disease duration in this cohort of patients with disease onset in the 1980s was not significantly increased compared to age- and sex-matched controls. No RA disease-related factor predicted mortality.

- Objective: To study the prevalence of orthopaedic surgery and to evaluate possible predictive factors for large joint replacements in patients with early rheumatoid arthritis (RA). Patients and methods: A cohort of 183 patients (116 (63.4%) female) with early RA was monitored for 16-20 years after recruitment during 1985-9. Mean (SD) age of patients 51.4 (12.4) years; mean (SD) duration of symptoms before inclusion 12 (7) months and mean (SD) duration of follow-up 16 (4) years. Occurrence of orthopaedic surgery was recorded continuously. A first prosthesis of a large joint (shoulder, elbow, wrist, hip, knee or ankle) was used as outcome variable in the predictive analyses. Results: In total, 386 orthopaedic interventions were performed in 106/183 (58%) patients during follow-up and a large joint replacement was performed in 44/183 (24%) patients. Using a Cox regression model, it was shown that Health Assessment Questionnaire, C-reactive protein and erythrocyte sedimentation rate at inclusion, and radiographic changes in small joints after 1 year, were associated with an increased risk of receiving prosthesis of large joints. Conclusion: In this cohort of patients with RA monitored from early disease stage, orthopaedic surgical procedures were performed in more than half of the patients. This included first large joint replacements in 24% of the cases. Easily available measures were identified as predictors of such joint replacements. This study could serve as a reference for comparison with cohorts of patients with RA recruited today, in which new more efficacious treatments are used.

- Objectives: To study the prevalence of comorbid conditions at diagnosis and during follow-up in a cohort of patients with early rheumatoid arthritis (RA) followed prospectively over 20 years, and to identify possible early predictive factors for future comorbidities. Methods: A community-based cohort of 183 patients (mean age 52 years, 63% female) with early RA was recruited between 1985 and 1989. The presence of comorbidity at RA diagnosis and the occurrence of additional comorbidities were recorded continuously. Possible predictors of future comorbidities were analysed using the Cox proportional hazards model. Results: At RA diagnosis, at least one comorbid condition was present in 43% of the patients. Cardiovascular diseases (CVDs), including hypertension (16% of patients) and malignancy (6% of patients), were most common. In total, 82% of patients developed additional comorbidities during follow-up. CVD and malignancies remained the most frequent comorbidities. Higher age [p < 0.001, odds ratio (OR) 1.03, 95% confidence interval (CI) 1.01-1.15] and the presence of any comorbidity at diagnosis (p = 0.02; OR 1.64, 95% CI 1.08-2.52) predicted future comorbidity. Measures of inflammation at diagnosis or during follow-up were not predictive for development of CVD. Conclusion: Comorbidity was present in a considerable proportion of patients in this cohort. More than 40% of patients had another disease at inclusion and during follow-up and > 80% developed additional conditions. The pattern of comorbidity remained unchanged, with CVD and malignancy being most common. Older age and the presence of comorbidity at RA diagnosis predicted the development of comorbidities. The degree of inflammation at any time point was not predictive of future CVD.

- Physical, psychological, and social features were assessed with standardized methods in 84 early RA patients followed prospectively for 2 years. During this time disease activity decreased, and disability evaluated by HAQ remained small. Psychological distress measured by SCL-90 (Symptom Check List) was in general not very pronounced and fairly stable over time. A high pain level at baseline provided a 4 times higher risk for a high level of psychological distress after 2 years. The prevalence of early retirement was 37% at the end of the study. Physical demanding work and a high initial HAQ score were the best predictors of work disability, increasing the risk of not working 10.7 and 5.5 times, respectively. At least 28% of patients had lower annual income compared to the year before disease onset. The ability to do shopping, home work, leisure time activities and social activities were negatively influenced by the disease in more than half of the patients. The social and economical consequences were thus considerable in the early stages of RA.
