Abstract
OBJECTIVE To assess disability and functioning of elderly patients with rheumatoid arthritis (RA) and population controls by linking the items included in the self-report Multidimensional Health Assessment Questionnaire (MDHAQ) with components of the WHO International Classification of Functioning, Disability and Health (ICF) instrument. METHODS In total, 1439 patients with RA (mean age 66 yrs, men 29%) and 957 population controls (65 yrs, men 27%) completed a mailed questionnaire. Functioning was recorded by the Finnish version of MDHAQ. Data included comorbidity, subjective health, education level, employment, exercise habits, self-report joint pain/tenderness, and, for patients, the disease duration. RESULTS Patients had lower levels of functioning compared to controls in all ICF domains, with the exception that male patients functioned comparably to male controls in the "general tasks and demands" domain. In patients, disease activity, education, exercise frequency, and comorbidities were expectedly associated with lower functioning in the body structure and function component, while male sex and subjectively perceived health were associated with more favorable functioning. In the activity and participation components, disease activity, exercise frequency, and comorbidities were associated with impaired functioning, while better health on self-report was associated with better functioning. CONCLUSION There is an extra burden of disability in elderly patients with RA compared to the reference population. With a large patient and control population sample, our study shows that use of the self-report MDHAQ identifies all 3 main components of the ICF framework, thus covering a wide spectrum of functioning. Elderly patients with RA, in comparison to population controls, encounter more difficulties in daily activities and their social life.

Abstract
Because of its high prevalence, fibromyalgia (FM) is a major general health issue. Myotonic dystrophy type 2 (DM2) is a recently described autosomal-dominant multisystem disorder. Besides variable proximal muscle weakness, myotonia, and precocious cataracts, muscle pain and stiffness are prominent presenting features of DM2. After noting that several of our mutation-positive DM2 patients had a previous diagnosis of FM, suggesting that DM2 may be misdiagnosed as FM, we invited 90 randomly selected patients diagnosed as having FM to undergo genetic testing for DM2. Of the 63 patients who agreed to participate, 2 (3.2%) tested positive for the DM2 mutation. Their cases are described herein. DM2 was not found in any of 200 asymptomatic controls. We therefore suggest that the presence of DM2 should be investigated in a large sample of subjects diagnosed as having FM, and clinicians should be aware of overlap in the clinical presentation of these 2 distinct disorders.

Abstract
OBJECTIVE To examine treatment induced changes in health-related quality of life (HR-QoL) in patients with early rheumatoid arthritis (RA). METHODS Changes in HR-QoL were assessed by the Nottingham Health Profile (NHP) instrument in 62 consecutive working age patients with recent onset RA with duration of symptoms of less than two years and naive with regard to disease-modifying antirheumatic drugs (DMARDs) and glucocorticoids. Treatment-response was assessed by the criteria of the European League against Rheumatism (EULAR; 28-joint score; DAS28) at 6 months. RESULTS NHP mean scores for pain (p=0.029) and emotional reaction (p=0.035) at baseline were related to EULAR response at 6 months, i.e. non-responders had the poorest baseline HR-QoL scores. When the patients were grouped according to EULAR response at 6 months there was a statistically significant mean linear change to better HR-QoL in NHP energy (p=0.0023), pain (p<0.001) and mobility (p=0.0085) from baseline to 6 months from the lowest to highest treatment-response level. CONCLUSION Our results show that good treatment-response as measured by the EULAR response criteria translates into improved HR-QoL dimensions for energy, pain and mobility.

Abstract
Fibromyalgia is a controversial pain syndrome with chronic widespread pain (occurring on both sides of the body as well as axially below and above the waist) and unexplained fatigue as the predominating features. Fibromyalgia involves lots of symptoms focusing on different organ systems. In sensory examination the most significant finding is general allodynia. The widespread chronic pain and tender points at certain locations as reported by the patient differentiate fibromyalgia patients from those suffering from other diseases of the musculoskeletal system.

Abstract
Anti-citrulline antibodies are highly specific to rheumatoid arthritis (RA) and are thus helpful in differential diagnosis. Early and aggressive disease modifying anti-rheumatic drug (DMARD) therapy is essential for a positive treatment result in cases of RA. Remission during the 1st year of treatment predicts permanent remission, milder joint damage and better functional ability. It is recommended that patients with an unsatisfactory response to DMARDs, including methotrexate and a combination of DMARDs, should be treated primarily with TNF blockers, and non-responders with rituximab or abatacept. RA is an independent risk factor for cardiovascular diseases. The assessment of cardiovascular risk must not be forgotten in daily practice.

Abstract
OBJECTIVE To develop a continuous composite index of disease activity for rheumatoid arthritis (RA) based on the 7 American College of Rheumatology (ACR) core data set of disease activity measures: Mean Overall Index for Rheumatoid Arthritis (MOI-RA). METHODS The MOI-RA is the mean of standardized values of tender and swollen joint counts (28, 42, or 66/68 joint counts), physical function (Health Assessment Questionnaire 0-3), patient's and physician's assessments of global health and patient's assessment of pain (visual analog scale 0-100 mm) and erythrocyte sedimentation rate (1-100). All the 7 components were standardized (0-100), and the mean of standardized values was calculated. The range of MOI-RA is 0-100; higher values indicate poorer outcomes. The validity and measurement properties of MOI-RA were analyzed in 169 patients in the Finnish RA Combination therapy trial. RESULTS The mean MOI-RA28 decreased from 38.5 to 13.3 [standardized response mean (SRM) = 1.8, effect size (ES) = 1.9] from baseline to 6 months, compared to Disease Activity Score (DAS) 28, which decreased from 5.55 to 2.77 (SRM = 2.0, ES = 2.8). Correlation between MOI-RA28 and DAS28 was 0.90. When compared to the ACR response categories (20/50/ACR remission), changes in MOI-RA versions (using 28/42/66 joints) were similar. The reproducibility of MOI-RA with different joint counts was 0.97. A simulation in which 15% of the component values of MOI-RA were randomly omitted indicated an intraclass correlation coefficient of 0.98 between incomplete and complete data. CONCLUSION MOI-RA is a simple and feasible index based on the ACR core data set of disease activity measures for assessment of disease activity and treatment response in RA trials and clinical settings.

Abstract
OBJECTIVE To study the effect of isometric neck strength exercises on upper cervical stability in patients with rheumatoid arthritis (RA). METHODS Twenty patients with a mean (SD) age of 58 (9) years and duration of RA of 27 (10) years volunteered for the study. Lateral radiographs of the cervical spine were taken to measure the current atlantoaxial distance (AAD) in flexion and extension. Maximal isometric neck flexion and extension strength values were measured by a dynamometer. Thereafter, AADs were measured from radiographs taken at 80-90% resistance of maximal strength. RESULTS According to the full flexion radiographs at baseline, the patients were classified into three groups: eight patients without anterior atlantoaxial subluxation (aAAS) [AAD = 2.1 (2-3) mm], seven with unstable aAAS [AAD = 6.6 (5-8) mm], and five with stable aAAS [AAD = 5.5 (5-7) mm]. During resisted flexion the AAD decreased by 5 (3-7) mm (p<0.001) in the unstable aAAS group, while in the other two groups the changes were minor. During resisted extension the AAD increased by 3 (2-6) mm (p<0.001) in the cases with unstable aAAS only. CONCLUSION Isometric exercising towards flexion decreases the AAD in cases with unstable aAAS. Submaximal loading of the neck extensors by pushing the back of the head against the resistance even in the neutral position of the cervical spine leads to a decrease in the width of the cervical spine canal and is not recommended in unstable aAAS.

Abstract
Objective: To compare the effectiveness of a 12-month home-based combined strength training and stretching programme against stretching alone in the treatment of chronic neck pain. Design: A randomized follow-up study. Participants: One hundred and one patients with chronic non-specific neck pain were randomized in two groups. Intervention: The strength training and stretching group was supported by 10 group training sessions and the stretching group was instructed to perform stretching exercises only as instructed in one group session. Main outcome measurements: Neck pain, disability, neck muscle strength and mobility of cervical spine were measured before and after the intervention. Results: No significant differences in improvement in neck pain and disability were found between the two training groups. Mean (SD) pain decreased from 64 (17) mm by 37 (95% confidence interval (CI) 44 to 30) mm in the strength training and stretching group, and from 60 (17) mm by 32 (39 to 25) mm in the stretching group. The improvements in disability were significant in both groups ( P<0.001), while the changes in neck strength and mobility were minor. Training adherence decreased over time from the targeted three sessions a week, ending up at 1.1 (0.7) times a week for strength training and stretching group and 1.4 (0.8) times a week for stretching group. Conclusions: No statistically significant differences in neck pain and disability were observed between the two home-based training regimens. Combined strength training and stretching or stretching only were probably as effective in achieving a long-term improvement although the training adherence was rather low most of the time.

Abstract
OBJECTIVE To examine the influence of components of the Disease Activity Score 28 (DAS28) [tender joint count (TJC), swollen joint count (SJC), patient's general health (GH), and erythrocyte sedimentation rate (ESR)] on the total DAS28 score, and overlapping of the 4 individual components in rheumatoid arthritis (RA) patients with low, moderate, or high disease activity. METHODS The effect of each component was studied in the FIN-RACo trial patients at 6 months and in a "theoretical model," where each component of the DAS28 ranged as follows: TJC and SJC from 0 to 28, GH from 0 to 100, and ESR from 1 to 100, while the other 3 components were 0 (ESR1). Overlapping of the components was studied in the FIN-RACo trial patients at 6 months with low (DAS28 < or = 3.2), moderate (DAS28 > 3.2 and < or = 5.1), and high (DAS28 > 5.1) disease activity. The higher limit for overlapping was defined as the highest SJC in the low disease activity group, and the lower limit as the lowest SJC in the high disease activity group; the percentage of patients who fall between these limits represent overlapping in SJC. Overlapping was calculated similarly concerning TJC, ESR, and GH. RESULTS ESR had the greatest effect on DAS28, followed by TJC, GH, and SJC, while in the "theoretical model" TJC had the greatest effect on the DAS28, followed by ESR, SJC, and GH. At 6 months, overlapping was present in 54%, 45%, 49%, and 31% of patients in SJC, TJC, GH, and ESR, respectively. CONCLUSION In real-life patients, ESR had the greatest effect of the 4 components of DAS28 on the total DAS28 score. The values of the individual components of DAS28 overlap considerably among the 3 disease activity groups.

Abstract
OBJECTIVE To study interleukin (IL)-1beta levels in recent onset RA patients treated either with combination DMARD therapy (sulfasalazine, methotrexate, hydroxychloroquine) or a single DMARD therapy. METHODS Serum IL-1beta levels were measured before the treatment and 6 months after the institution of either single or combination DMARD therapy using a high sensitivity ELISA method. Radiographic evaluation of the hands and feet was performed at 0 and 24 months. RESULTS Significant correlations (r = 0.28, 95% CI 0.10-0.45) were found between IL-1beta levels measured at 0 and 6 months. The IL-1beta levels at 0 months correlated significantly (r = 0.23, 95% CI 0.03-0.4, p= 0.021) with the baseline number of eroded joints at 0 months but not with radiographic joint damage at 24 months. The baseline level of IL-1beta was a better indicator for the presence of eroded joints than the baseline level of serum CRP. No significant changes in IL-1beta levels were observed during the first 6 months of anti-rheumatic treatment in either group. No statistically significant difference between IL-1beta levels in the patients with or without the shared epitope could be observed. CONCLUSIONS The serum IL-1beta level is significantly associated with the presence of erosions at the onset of RA but its predictive value is attenuated or lost when single or combination DMARD medication is instituted. Measuring IL-1beta at the time of diagnosis in a single patient cannot be used to estimate the erosive nature of the disease or the prognosis.

Abstract
OBJECTIVE To analyse the proportion of individuals in the general population over age 50 who do not meet American College of Rheumatology (ACR) criteria for rheumatoid arthritis (RA) remission, and OMERACT criteria for minimal disease activity (MDA), and to compare results to RA patients. METHODS A self-report questionnaire was completed by 1400 community control subjects and 1705 RA patients, including the Health Assessment Questionnaire (HAQ), gradual rating scales for pain, fatigue and global health, duration of morning stiffness and painful joints. The prevalence of 4/6 ACR remission criteria and 4/7 OMERACT criteria for MDA was analysed in community control subjects and patients with RA over age 50. RESULTS For ACR criteria, 76% of control subjects reported painful joints, 37% morning stiffness, 62% pain and 66% fatigue, vs 94, 65, 84 and 84% of patients with RA. MDA criteria were not met by 64% of control subjects for painful joints, 38% for pain, 45% for global health and 18% for HAQ, vs 89, 60, 69 and 52% of RA patients. The four ACR remission criteria were met by only 15% of control subjects over age 50 and 3% of RA patients, and MDA criteria by 28% of controls and 7% of patients. CONCLUSIONS The majority of community population over age 50 did not meet criteria for remission or MDA in RA. Although a self-report format may differ from results involving an assessor, the current criteria may not be accurate to identify remission or MDA in people with RA who are older than age 50.

Abstract
OBJECTIVE To study sustainability of remission and good treatment response, and the association of both with radiographic progression, in early rheumatoid arthritis (RA) in the Finnish Rheumatoid Arthritis Combination Therapy trial (FIN-RACo). METHODS Patients were randomized to receive either a combination of disease modifying antirheumatic drugs (DMARD; COMBI, n = 97) or a single DMARD (SINGLE, n = 98). Remission was defined according to modified American College of Rheumatology (ACR) remission criteria and Disease Activity Score 28 joint count (DAS28) < or = 2.6, and sustained remission as presence of remission at 6, 12, and 24 months. Good treatment response was defined as DAS28 (3/4) 3.2 and decrease of DAS28 >1.2. RESULTS In 169 patients with complete data, 33 (42%) COMBI and 18 (20%) SINGLE patients achieved modified ACR remission at 2 years, which was sustained in 11 (14%) COMBI and 3 (3%) SINGLE patients. Fifty-four (68%) COMBI and 37 (41%) SINGLE patients were in DAS28 remission at 2 years, which was sustained in 40 (51%) COMBI and 14 (16%) SINGLE patients. Good treatment response was sustained in 67% of COMBI and 27% of SINGLE patients. Over 2 years, the Larsen score increased by a median of 1 (95% CI 0-2) in patients in sustained DAS28 remission compared to 4 (95% CI 2-16) in patients who were in DAS28 remission at 6 months but lost it later; and by 6 (95% CI 2-10) in patients who were not in remission at 6 months. CONCLUSION A remarkable proportion of patients with early RA treated with combinations of DMARD were in remission at 2 years, and remission was more often sustained compared to patients treated with a single DMARD. Sustained remission protects against radiographic joint damage.

Abstract
OBJECTIVE To determine whether early inflammatory activity in the first year of disease compared to persistent or later occurrence of swelling or tenderness in the wrist joints is associated with 5-year erosions in the same joint in patients with early rheumatoid arthritis (RA). METHODS A cohort of 195 patients with early active RA was enrolled in the Finnish RA Combination Trial. Swelling and tenderness of wrists were assessed at baseline and at 3, 6, 12, 24, 36, and 48 months. Radiographs of the wrists were taken at the baseline and at 5 years. The 237 wrist joints of 125 patients without erosions at baseline were classified according to wrist swelling, i.e., I: never swollen; II: swollen during first year only; III: swollen during the second to fourth year only; and IV: swollen during the first year and followup, and similarly according to tenderness. RESULTS Thirty percent of the wrists were never swollen in all clinical examinations; 43% were swollen only during the first year; 11% were not swollen in the first year, but were swollen at some time during 24-48 months; and 16% of wrists were swollen during the first year and at some time during 24-48 months. At 5 years, 64% of 237 wrists remained free of erosions. Erosions developed in 82% of wrists that were swollen during both the first year and 24-48 months, versus 56% of wrists that were not swollen at first year but were swollen during 24-48 months, 31% of wrists that were swollen during the first year only, and 11% of wrists that were never swollen. Similar results were seen for joint tenderness. CONCLUSION Wrist swelling during the first year only is associated with less future wrist radiographic damage than persistent swelling or swelling only during the followup. Our results emphasize the value of early and continuous suppression of inflammatory activity in early RA.

Abstract
OBJECTIVE To analyze longitudinal data over 5 years for changes in Health Assessment Questionnaire (HAQ) scores in patients with rheumatoid arthritis (RA) and age- and sex-matched controls from the general population. METHODS In 2000 and 2005, identical self-report questionnaires were mailed to a cohort of patients with RA and control cohort from the community. The questionnaire included the HAQ, which was used to assess functional status. Changes in HAQ scores over 5 years were analyzed. RESULTS In 2000, 73% of 1,495 patients with RA and 77% of 2,000 general population controls responded to the questionnaire. In 2005, 84% of 2,022 patients with RA and 77% of 1,817 controls responded. A total of 863 patients with RA and 1,176 community controls responded in both 2000 and 2005 and were included in the analyses. Mean baseline HAQ scores were significantly higher in patients with RA than in controls (0.71 versus 0.17; P < 0.001). Over 5 years, the HAQ scores increased by 0.01 units per year in both the RA cohort and the community population; in both cohorts, the net change was primarily attributable to individuals over age 70 years. Changes in HAQ scores were similar in patients and controls who had low HAQ scores at baseline. Female patients with baseline HAQ scores of >or=0.5 had less potential for improvement than did controls. Among subjects in both groups who had HAQ scores >2, death was a common outcome over the next 5 years. CONCLUSION Currently, progression of functional disability among patients with RA and among persons in the general population is largely explained by the aging process. Our results showing stable function scores over 5 years in most patients with RA who are younger than age 70 years provide further evidence of improved status of RA patients today compared with the major declines observed in previous decades.

Abstract
Various definitions of remission in rheumatoid arthritis (RA) have been proposed. The ACR (American College of Rheumatology--formerly ARA, American Rheumatism Association) remission criteria are strict and include nonspecific symptoms such as fatigue. More recently remission according to the Disease Activity Index (DAS) and DAS28 has been described. However, patients who meet the DAS28 remission cut point of < 2.6 may nonetheless have tender and/or swollen joints. The ACR remission criteria are more rigorous than the requirement of DAS28 <2.6. Newer tools for evaluation of RA activity include the Simplified Disease Activity Index (SDAI) and Clinical Disease Activity Index (CDAI), and cut points for remission according to these new indices have been defined. However, all available remission criteria may ignore important aspects of RA, including physical function and radiographic damage.

Abstract
OBJECTIVE To study the associations of tumor necrosis factor (TNF) a, b and c microsatellite markers with 1) the clinical disease activity and 2) the induction of remissions in patients with early rheumatoid arthritis (RA) treated with two treatment strategies. METHODS In the FIN-RACo (FINnish Rheumatoid Arthritis Combination therapy) trial of two years, 195 patients with recent-onset RA were randomly assigned to receive either a combination (COMBI) (sulphasalazine, methotrexate, hydroxychloroquine, and prednisolone) or a single (SINGLE) (initially sulphasalazine with or without prednisolone) disease modifying antirheumatic drug (DMARD) therapy. TNF a, b and c microsatellite and HLA-DRB1 typings were carried out in 165 (79 COMBI; 86 SINGLE) study completers. RESULTS At baseline the 28 joint disease activity scores (DAS28) of the patients positive for TNFa2, a13 or b1 microsatellite markers were significantly higher than in the other patients. In the SINGLE patients the DAS28 improved comparably in patients with (n = 31) or without (n = 53) the TNFb1 marker (NS), while the DAS28 of the TNFb1-positive COMBI patients (n = 22) improved significantly more than that of the TNFb1-negative cases (n = 57) (p = 0.014). Respective 31.8% (7/22) and 28.1% (16/57) of the COMBI patients with or without TNFb1 allele achieved remission at one year. The corresponding figure in SINGLE patients were 0% (0/31) and 20.8% (11/53) (p = 0.006). At two years the remission frequencies in the TNFb1+/TNFb1- patients in the COMBI and SINGLE were 50.0%/38.6% and 9.7%/22.6%, respectively. CONCLUSION Early TNFb1+ RA patients have more active disease but respond more favourably to COMBI treatment than the patients without this microsatellite allele. The finding may be of clinical relevance for the choice of DMARDs in early RA.

Abstract
The Finnish Rheumatoid Arthritis Combination Therapy (FIN-RACo) trial is the first rheumatoid arthritis (RA) clinical trial in which remission served as the primary outcome measure. This chapter reviews the philosophical background, study design, and results of the FIN-RACo trial. The study showed that a third of patients with active early RA may achieve remission with a combination of methotrexate (MTX), sulfasalazine (SSZ), hydroxychloroquine (HCQ), and prednisolone.

Abstract
BACKGROUND Total joint replacement (TJR) surgery is an important severe long-term outcome of rheumatoid arthritis, but relatively little is known about changes of its incidence in patients with rheumatoid arthritis over the past two decades. METHODS A population-based, retrospective, incidence case review was conducted to analyse the frequency of primary TJR surgery of the knee and hip in all patients, and specifically in patients with rheumatoid arthritis in Central Finland between 1986 and 2003. Patients with TJR surgery of the knee and hip were identified in hospital databases over the 18-year period. Age-standardised incidence rate ratios for the primary TJR of the knee and hip were calculated, stratified to sex and diagnosis, with 1986 as the reference value. RESULTS In patients without rheumatoid arthritis the age-adjusted incidence rate ratios (with 95% CI) for TJR of the knee increased 9.8-fold from 1986 to 2003 in women and men, and for TJR of the hip 1.8-fold in women and 2-fold in men. By contrast, no meaningful change was seen over this period, in age-adjusted incidence rate ratios for TJR of the knee or hip in patients with rheumatoid arthritis, ranging from 0.7 to 1.2 in 2003 compared with 1986. CONCLUSION The prevalence of TJR surgery has increased 2-10-fold in patients without rheumatoid arthritis patients, associated with an ageing population, but has not increased in patients with rheumatoid arthritis between 1986 and 2003. These data are consistent with emerging evidence that long-term outcomes of rheumatoid arthritis have improved substantially, even before the availability of biological agents.

Abstract
OBJECTIVE To explore the monetary value of rheumatoid arthritis related loss of productivity in patients with early active disease. METHODS In a prospective cohort substudy of the FIN-RACo Trial, 162 patients with recent onset rheumatoid arthritis, aged 18 to 65 years and available to the workforce, were followed up for five years. Loss of work productivity in euros 2002 was estimated by data on absence for sickness and on income (human capital approach) from official databases. Treatment responses were evaluated by area under the curve (AUC) of the ACR-N measure and by increase in number of erosions in radiographs of hands and feet. The health assessment questionnaire (HAQ) at six months was linked to the International Classification of Functioning, Disability and Health (ICF). RESULTS In all, 120 (75%) patients, women more often (82%) than men (61%) (p=0.002), lost work days. The mean lost productivity per patient-year was euro7217 (95% confidence interval (CI), 5561 to 9148): for women, euro6477 (4858 to 8536) and for men, euro8443 (5389 to 12,898). There was an inverse correlation with improvement: euro1101 (323 to 2156) and euro14 952 (10,662 to 19,852) for the highest and lowest quartiles of AUC of ARC-N, respectively. Lost productivity was associated with increase in the number of erosions and with disability in "changing and maintaining body position" subcategory of the ICF. CONCLUSIONS Despite remission targeted treatment with disease modifying antirheumatic drugs, early rheumatoid arthritis results in substantial loss of productivity. A good improvement in the disease reduces the loss markedly.

Abstract
The aim of this study was to determine whether the +896 A-->G substitution of the Toll-like receptor 4 (TLR4) gene, causing the Asp299-->Gly change in the extracellular domain of TLR4, influences treatment response in recent-onset rheumatoid arthritis. 169 patients with rheumatoid arthritis were genotyped from the Finnish Rheumatoid Arthritis Combination Therapy trial, in which they were treated either with only one disease-modifying antirheumatic drug (DMARD) with or without prednisolone (single group), or with three DMARDs and prednisolone (combination group). Patients homozygotic for the wild-type +896A allele were compared with those having the polymorphic G allele in terms of early clinical response (at 6 months) by the 28-joint Disease Activity Score (DAS28). 1 of 20 (5%; (95% (confidence interval (CI) 1 to 5)) patients of the single group with TLR4 +896AG or GG and 29 of 67 (43%; (95% CI 31 to 56)) patients with AA were in remission (p = 0.001). DAS28 of the single group with TLR4 +896AG or GG was higher than with AA (p = 0.019). In the combination group, remission rates and DAS28 values were comparable between the genotypes. The polymorphic TLR4 +896G allele may impair treatment response to single DMARD treatment in recent-onset rheumatoid arthritis.

Abstract
OBJECTIVE To examine heavy-resistance exercise-induced acute neuromuscular fatigue, blood lactate concentration, and muscle pain in elderly women with fibromyalgia (FM) and in healthy controls before and after a period of strength training. METHODS Thirteen elderly women with FM (mean+/-SD age 60+/-2 years) and 10 healthy women (mean+/-SD age 64+/-3 years) performed a heavy-resistance fatiguing protocol (5 sets of leg presses with 10 repetitions maximum) before and after a 21-week strength training period. Maximal isometric force and electromyography (EMG) activity of leg extensors and blood lactate concentration were measured during the loading. Pain was assessed by visual analog scale. RESULTS The strength training led to large increases in maximal force and EMG activity of the muscles and contributed to the improvement in loading performance (average load/set) at week 21. The fatiguing loading sessions typically applied in strength training before and after the experimental period caused remarkable and comparable acute decreases in maximal force and increases in blood lactate concentration in both groups. Acute exercise-induced muscle pain increased similarly in both groups, and the pain level in women with FM was lowered after the 21-week training period. CONCLUSION The increased strength in women with FM improved high-load performance and also seemed to attenuate perceived pain. Acute exercise-induced neuromuscular changes and the time course of muscle pain in women with FM were comparable with findings in healthy controls, which suggests a typical fatiguing process and a similar trainability of the muscles in elderly women with FM.

Abstract
OBJECTIVE To examine the effects of strength training on maximal force, cross-sectional area (CSA), and electromyographic (EMG) activity of muscles and serum hormone concentrations in elderly females with fibromyalgia (FM). METHODS Twenty-six patients with FM were randomly assigned to a training (FMT; n = 13; mean age 60 years) or a control (FMC; n = 13; 59 years) group. FMT performed progressive strength training twice a week for 21 weeks. The measurements included maximal isometric and concentric leg extension forces, EMG activity of the vastus lateralis and medialis, CSA of the quadriceps femoris, and serum concentrations of testosterone (T), free testosterone (FT), growth hormone (GH), insulin-like growth factor-1 (IGF-1), dehydroepiandrosterone sulfate (DHEAS), and cortisol. Subjectively perceived symptoms of FM were also assessed. RESULTS All patients were able to complete the training. In FMT strength training led to increases of 36% (p<0.001) and 33% (p<0.001) in maximal isometric and concentric forces, respectively. The CSA increased by 5% (p<0.001) and the EMG activity in isometric action by 47% (p<0.001) and in concentric action by 57% (p<0.001). Basal serum hormone concentrations remained unaltered during strength training. The subjective perceived symptoms showed a minor decreasing tendency (ns). No statistically significant changes occurred in any of these parameters in FMC. CONCLUSION Progressive strength training increases strength, CSA, and voluntary activation of the trained muscles in elderly women with FM, while the measured basal serum hormone concentrations remain unaltered. Strength training benefits the overall physical fitness of the patients without adverse effects or any exacerbation of symptoms and should be included in the rehabilitation programmes of elderly patients with FM.

Abstract
OBJECTIVE To study the prevalence of cervical spine subluxation in patients with rheumatoid arthritis waiting for orthopaedic surgery, and symptoms that might be associated with the disorders. METHODS 194 patients with rheumatoid arthritis were referred for orthopaedic surgery at Jyväskylä Central Hospital, 154 (79%) of whom volunteered for the present study including clinical examination, laboratory tests, radiographs of the cervical spine, hands, and feet, and self report questionnaires. Definition of anterior atlantoaxial subluxation (aAAS) was >3 mm and of subaxial subluxation (SAS)>or=3 mm. Atlantoaxial impaction (AAI) was analysed following to the Sakaguchi-Kauppi method. RESULTS 67 patients (44%) had cervical spine subluxation or previous surgical fusion. The prevalence of aAAS, AAI, SAS, or previous fusion was 27 (18%), 24 (16%), 29 (19%), and 8 (5%), respectively; 69% of patients with cervical spine subluxations (those with fusions excluded) reported neck pain, compared with 65% of patients without subluxations (p=0.71). The prevalence of occipital, temporal, retro-orbital, and radicular pain in upper extremities was similar in patients with or without cervical spine subluxations (54% v 43%; 17% v 31%; 25% v 24%; 47% v 48%, respectively). However, patients with subluxations were older, had longer disease duration, more active disease, poorer function according to the Health Assessment Questionnaire, and had more often erosive disease. CONCLUSIONS Asymptomatic cervical spine subluxation is common in patients with rheumatoid arthritis waiting for orthopaedic surgery. Regardless of symptoms, the possibility of cervical spine subluxation in patients with severe rheumatoid arthritis should be considered in preoperative evaluation.

Abstract
This article reviews the use of conventional disease-modifying antirheumatic drugs (DMARDs) in the treatment of early rheumatoid arthritis (RA). The Finnish early RA cohorts are used as examples of how early and active treatment strategies have improved over time with increasing variety of available DMARDs. Therapy goals of early RA include remission to prevent severe long-term outcomes of RA. Remission can be achieved in a third of patients with early RA using a combination of conventional DMARDs, including methotrexate, sulfasalazine, hydroxychloroquine, and prednisolone. Of patients with early RA, 20% to 30% do not improve enough with conventional treatments and should be identified at early phases to consider institution of biologic agents.

Abstract
OBJECTIVE To compare neck muscle strength and mobility of the cervical spine in rheumatoid arthritis (RA) patients with and without atlantoaxial (AA) disorders (anterior atlantoaxial subluxation [AAS], AA impaction). DESIGN Clinical cross-sectional study. SETTING Outpatient rheumatology and rehabilitation clinics in a Finnish hospital. PARTICIPANTS Patients with RA (N=124; mean age +/- standard deviation, 62+/-12y [corrected]) on a waiting list for orthopedic surgery. Thirty (24%) patients presented with AA disorders (16 with anterior AAS, 8 with AA impaction, 6 with a combination of anterior AAS and AA impaction). INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Neck function was measured by isometric neck strength and mobility tests, neck pain by a visual analog scale, erosion of the hands and feet by radiography, and the patients' function by the Health Assessment Questionnaire (HAQ). RESULTS Maximal neck muscle strength against flexion, extension, and rotation was lower in patients with AA disorders compared with the other patients in both women (P=.012) and men (P=.017). Mobility was lowest in the AA impaction group in all measured directions (P<.001). Peripheral erosive disease was more frequent in the group with AA disorders. They also had longer disease duration and were more disabled (HAQ) than the other patients. CONCLUSIONS Neck muscle strength is significantly decreased in patients with AA disorders. Mobility of the cervical spine is most limited in patients with AA impaction, but can be normal in cases with solitary anterior AAS.

Abstract
OBJECTIVE The effects of a 21-week combined strength and endurance training period on physical fitness, serum hormone concentrations, and subcutaneous fat in 23 women with rheumatoid arthritis (RA) and in 12 matched healthy subjects was studied. METHODS The measurements included leg extension forces and EMG activity, muscle and fat thickness on thigh, maximal oxygen uptake (VO2max) and serum concentrations of testosterone, free testosterone, growth hormone, insulin-like growth factor-I (IGF-I), dehydroepiandrosterone sulphate (DHEAS), and cortisol. RESULTS During the training period significant increases took place in VO2max, muscle strength and EMG activity in both groups. The increases of the quadriceps femoris thickness were 6.5% (p < 0.001) in the healthy controls and 7.4% (p < 0.001) in the RA cases. The decreases in subcutaneous fat thicknesses were 9.9% (p < 0.001) and 12.3% (p < 0.001), respectively. No significant changes were found in serum hormone concentrations, but RA women showed lower levels of IGF-I during the whole follow-up. CONCLUSIONS In RA women with stable disease the combined strength and endurance training increases physical fitness. Further the training increases muscle mass and decreases subcutaneous fat. It may decrease risks of cardiovascular diseases in RA patients. The intensive training had minor effects on serum hormone concentrations.

Abstract
OBJECTIVES To study which cut off point of DAS28 corresponds to fulfilment of the American Rheumatism Association (ARA) preliminary remission criteria, and clinical remission criteria in patients with rheumatoid arthritis (RA). METHODS All adult patients diagnosed with RA at Jyväskylä Central Hospital 1997-98 were assessed for remission at 5 years. Remission was defined as (a) ARA remission; (b) clinical remission (defined as no tender or swollen joints and normal erythrocyte sedimentation rate). DAS28 was used to measure disease activity. A receiver operating characteristics curve analysis was performed to calculate a cut off point of DAS28 that best corresponds to the ARA remission criteria and the clinical remission criteria. RESULTS 161 patients (mean age 57 years, 107 (66%) female, 98 (61%) with positive rheumatoid factor, and 51 (32%) with erosions) were studied. At 5 years, 19 (12%) patients met the ARA remission criteria, and 55 (34%) met the clinical remission criteria. The cut off value of DAS28 was 2.32 for the ARA remission criteria, and 2.68 for the clinical remission criteria. In patients with DAS28 <2.32, 11/57 (19%) had tender joints, 6/57 (11%) had swollen joints, and 4/57 (7%) had both tender and swollen joints (66 joint count). CONCLUSION In this study the DAS28 cut off point for the ARA remission was lower than in previous studies. The cut off point for DAS28 remission remains controversial. A substantial proportion of patients below the DAS28 cut off point for remission have tender or swollen joints, or both. DAS28 may not be an appropriate tool for assessment of remission in RA.

Abstract
OBJECTIVE To study the extent to which muscle strength and performance, pain, and disease activity are associated with the total Health Assessment Questionnaire (HAQ) disability index and its subdimensions in male and female patients with rheumatoid arthritis. METHODS HAQ for functional capacity was completed by 135 patients with rheumatoid arthritis referred for orthopaedic surgery (74% women; mean (SD) age 62 (10) years; disease duration 19 (13) years, 70% positive for rheumatoid factor). Knee extension, trunk extension and flexion, grip strength, walking speed, and sit-to-stand test were measured to mirror physical function. Radiographs of hands and feet, pain, and the modified 28 joint disease activity score (DAS28) were also assessed. RESULTS Mean total HAQ was 1.08 (0.68) in women and 0.67 (0.70) in men (p = 0.0031). Women had greater disability than men in five of the eight subdimensions of the HAQ. Grip strength was 48%, knee extension strength 46%, trunk extension strength 54%, and trunk flexion strength 43% lower in women than in men. Knee extension strength was inversely correlated with walking time (r = -0.63 (95% confidence interval, -0.73 to -0.51)) and with sit-to-stand test (r = -0.47 (-0.60 to -0.31)). In an ordered logistic regression analysis in female rheumatoid patients, DAS28, pain, knee extension strength, and grip strength were associated with the total HAQ disability index. CONCLUSIONS Women reported greater disability than men both in the total HAQ and in the majority of its eight subdimensions. In addition to disease activity and pain, muscle strength has a major impact on disability especially in female rheumatoid patients.

Abstract
OBJECTIVE To determine whether nonresponse to a mailed health survey predicts mortality in patients with rheumatoid arthritis (RA) and in a community sample in Finland. METHODS A 5-page health questionnaire was administered in 2000. Two years later the vital status of the subjects was ascertained from the Population Registry. RESULTS A total of 1095 (73%) patients with RA and 1530 (77%) community control subjects returned a completed questionnaire. Over the 2-year period, the number of deaths was 57 (5.2%) in RA responders and 37 (9.3%) in RA nonresponders (p = 0.004). The corresponding figures in community controls were 34 (2.2%) and 23 (4.9%) (p = 0.002). In a Cox regression model adjusted for age and sex, RA patient and community control nonresponders were respectively 1.65 (95% CI 1.07 to 2.55) and 2.89 (95% CI 1.69 to 4.94) times more likely to die over the 2 years compared to the responders. CONCLUSION Nonresponders to a mailed health survey were more likely to die over 2 years compared to responders. The possible nonresponse bias should be kept in mind in the interpretation of the results of studies that are based on mail questionnaires only.

Abstract
OBJECTIVE To study the frequency of remission using 3 sets of criteria in patients with rheumatoid arthritis (RA) at 5 years after the diagnosis. METHODS All adult patients with recent onset inflammatory arthritis who did not meet criteria or show clinical signs of other specific arthritides were included in the RA1997 inception cohort at Jyväskylä Central Hospital, Finland, and were assessed for remission at 5-year control examination. Remission was defined as (1) American College of Rheumatology (ACR) remission (fatigue excluded), (2) clinical remission with no tender and no swollen joints and normal erythrocyte sedimentation rate, and (3) radiographic remission with no worsening of erosions and no new erosions from baseline to 5 years. RESULTS The study included 127 patients with early RA (mean age 56 yrs, 61% female, 54% with positive rheumatoid factor, and 25% with erosions). At 5 years, 111 patients were examined, 17% (95% CI 11%-25%) of whom met ACR remission criteria, 37% (95% CI 28%-47%) met clinical remission criteria, and 55% (95% CI 49%-68%) met radiographic remission criteria. Only 13 (12%) patients met all 3 sets of remission criteria. The rate of remission was statistically significantly different (p < 0.001) using the 3 sets. CONCLUSION The rate of remission in RA depends on the criteria used. No gold standard exists for defining remission in RA. A set of criteria including no sign of inflammatory activity and no radiographic progression might be a basis for development of clinically relevant remission criteria for RA.

Abstract
OBJECTIVE To determine to what extent health status impairment in rheumatoid arthritis (RA) measured by self report of pain, global assessment, and functional disability is attributable to age and other comorbid conditions as opposed to the disease itself. METHODS Pain, global assessment, and Health Assessment Questionnaire Disability Index (HAQ-DI) were measured in a random sample of 1530 adults in the Central Finland District, Finland. Median regressions were used for multivariable analyses. RESULTS The mean age was 55.4 years and 72% were women. A large majority of the population reported some pain (76%) and less than perfect general health (83%). The overall mean values of pain, HAQ-DI, and general health were 20 mm, 0.25 units, and 21 mm, respectively. The most common self reported musculoskeletal comorbidities were osteoarthritis (24%) and chronic back pain (25%). Age and number of comorbidities were the only statistically significant correlates of pain and general health in multivariable analyses. CONCLUSIONS Self reported disability, pain, and poor health were widely prevalent in the general population and are related to age and comorbid conditions. This needs to be taken into account when interpreting remission and response rates using current criteria and for future development of definitions for these end points in RA and other rheumatic diseases.

Abstract
OBJECTIVE To study the value of baseline serum levels of circulating soluble interleukin-2 receptor (sIL-2R) and soluble E-selectin as predictors of early remission in patients with recent-onset rheumatoid arthritis (RA) receiving a single disease-modifying anti-rheumatic drug (DMARD) (SINGLE) or therapy with a combination of DMARDs (COMBI). METHODS Baseline (n = 157) serum samples originate from the FIN-RACo (FINnish Rheumatoid Arthritis Combination therapy) trial, in which 195 patients with early and clinically active RA were randomly assigned to receive either SINGLE (initially sulfasalazine) with or without prednisolone, or COMBI therapy (sulfasalazine, methotrexate, hydroxychloroquine, and prednisolone). Of the samples, 76 were from SINGLE patients and 81 from COMBI patients. sIL-2R was measured by automated immunoassay analyzer and sE-selectin by enzyme-linked immunosorbent assay. RESULTS At six months, 7 (9% [95% CI: 4 to 18]) SINGLE and 19 (23% [95% CI: 15 to 34]) COMBI patients were in remission. In multivariate logistic regression analysis, sIL-2R <442 U/ml and COMBI therapy were the only predictors of remission. The area under receiver operating characteristic curve for sIL-2R level was 0.86 (95% CI: 0.62 to 0.95) in SINGLE and 0.57 (95% CI: 0.42 to 0.71) in COMBI (p = 0.006). In SINGLE, the optimal cut offpoint was 442 U/ml, lower levels predicting remission with sensitivity of 83% (95% CI: 73% to 91%) and specificity of 86% (95% CI: 42% to 100%). Likelihood ratio for positive test was 5.9 (95% CI: 1.6 to 32.8). In multivariate logistic regression analysis, sIL-2R <442 U/ml and COMBI therapy were the only predictors of remission. CONCLUSION Low baseline serum sIL-2R level predicts early remission of patients with active early RA treated with a single DMARD.

Abstract
OBJECTIVE To explore baseline risk factors for productivity loss and work disability over 5 years in patients with early, active RA. PATIENTS AND METHODS In the FIN-RACo trial, 195 patients with recent onset RA were randomised to receive either a combination of DMARDs with prednisolone or a single DMARD for 2 years. At baseline, 162 patients were working or available for work. After 5 years' follow up, data on sick leave and retirement were obtained from social insurance registers or case records. The cumulative duration of sick leaves and RA related disability pensions was counted for each patient. To analyse predictors of productivity loss, the patients were divided into four groups according to duration of work disability per patient year. RESULTS Patient's and physician's global assessment of RA severity > or =50 and HAQ score > or =1.0 were risk factors for extension of productivity loss (OR (95% (CI) 1.77 (1.00 to 3.16), 1.85 (1.03 to 3.32), and 1.78 (1.01 to 3.14), respectively). Additional risk factors were low education level (2.40 (1.18 to 4.88)) and older age (1.03 (1.00 to 1.06)); combination treatment was a protective factor (0.59 (0.35 to 0.99)). CONCLUSION At baseline, the risk of future productivity loss is best predicted by education level, age, global assessments of RA severity, and HAQ score.

Abstract
OBJECTIVE To explore the impact of an early treatment response on maintenance of work capacity in patients with early, active rheumatoid arthritis (RA). METHODS In the Finnish Rheumatoid Arthritis Combination Therapy trial, 195 patients with recent-onset RA were randomized to receive either a combination of disease-modifying antirheumatic drugs (DMARDs) with prednisolone or a single DMARD with or without prednisolone for 2 years. Treatment responses were evaluated according to the American College of Rheumatology (ACR) criteria. After a 5-year followup, the cumulative number of days of sick leave and RA-related permanent work disability was calculated for each of the 162 patients who were available for the active work force at baseline. RESULTS Of the 159 patients assessed at 6 months, 29 were in clinical remission, 66 achieved an ACR50 response but not remission, 29 achieved an ACR20 response but not an ACR50 response, and 35 failed to achieve an ACR20 response. In these 4 groups, the median numbers of work disability days per patient-year from 6 months through 60 months of followup were 0 (interquartile range [IQR] 0-3), 4 (IQR 0-131), 16 (IQR 0-170), and 352 (16-365), respectively (P < 0.001). Pairwise multiple comparisons showed a statistically significant difference between all groups except the ACR50 and ACR20 groups. At 12 months, 30 patients were in remission. None of the 44 patients in remission at 6 or 12 months became permanently work disabled over the 5-year followup, as compared with 15 patients in the ACR50 group (23%), 6 in the ACR20 group (21%), and 19 without an ACR20 response at 6 months (56%). CONCLUSION Prompt induction of remission translates into maintenance of work capacity. At 6 months, an ACR50 response is no better than an ACR20 response with regard to future productivity, while failure to achieve an ACR20 response carries a high risk for work disability.

Abstract
OBJECTIVES To elucidate the contribution of HLA-DR-DQ haplotypes and their genotypic combinations to susceptibility to rheumatoid arthritis, and to evaluate the various models for HLA associated risk for the disease in a series of Finnish patients. METHODS 322 Finnish patients with rheumatoid arthritis were typed for common north European HLA-DR-DQ haplotypes and compared with a series of 1244 artificial family based control haplotypes. RESULTS The association of the so called shared epitope (SE) haplotypes (DRB1*0401, *0404, *0408, and *01) with rheumatoid arthritis was confirmed. The DRB1*0401 haplotypes carried a far stronger risk for the disease than the (DRB1*01/10)-(DQA1*01)-DQB1*0501 haplotypes. Seven protective HLA haplotypes--(DRB1*15)-(DQA1*01)-DQB1*0602; (DRB1*08)-(DQA1*04)-DQB1*04; (DRB1*11/12)-DQA1*05-DQB1*0301; (DRB1*1301)-(DQA1*01)-DQB1*0603; (DRB1*1302)-(DQA1*01)-DQB1*0604; (DRB1*07)-DQA1*0201-DQB1*0303; and (DRB1*16)- (DQA1*01)-DQB1*0502--were identified. In accordance with the reshaped shared epitope hypothesis, all the protective DRB1 alleles in these haplotypes share either isoleucine at position 67 or aspartic acid at position 70 in their third hypervariable region motif. However, differences in the disease risk of haplotypes carrying the same DR but different DQ alleles were also found: (DRB1*07)-DQA1*0201-DQB1*0303 was protective, while (DRB1*07)-DQA1*0201-DQB1*02 was neutral. The same haplotypes carried different risks for rheumatoid arthritis depending on their combination in genotypes. CONCLUSIONS When assessing the influence of HLA genes on the susceptibility to rheumatoid arthritis, not only should the HLA-DR or -DQ alleles or haplotypes be unravelled but also the genotype. The effect of HLA class II region genes is more complicated than any of the existing hypotheses can explain.

Abstract
OBJECTIVE To evaluate the long-term frequency of disease remissions and the progression of joint damage in patients with early rheumatoid arthritis (RA) who were initially randomized to 2 years of treatment with either a combination of 3 disease-modifying antirheumatic drugs (DMARDs) or a single DMARD. METHODS In this multicenter prospective followup study, a cohort of 195 patients with early, clinically active RA was randomly assigned to treatment with a combination of methotrexate, sulfasalazine, hydroxychloroquine, and prednisolone or with a single DMARD (initially, sulfasalazine) with or without prednisolone. After 2 years, the DMARD and prednisolone treatments became unrestricted, but were still targeted toward remission. The long-term effectiveness was assessed by recording the frequency of remissions and the extent of joint damage seen on radiographs of the hands and feet obtained annually up to 5 years. Radiographs were assessed by the Larsen score. RESULTS A total of 160 patients (78 in the combination group and 82 in the single group) completed the 5-year extension study. At 2 years, 40% of the patients in the combination-DMARD group and 18% in the single-DMARD group had achieved remission (P < 0.009). At 5 years, the corresponding percentages were 28% and 22% (P not significant). The median Larsen radiologic damage scores at baseline, 2 years, and 5 years in the combination-DMARD and single-DMARD groups were 0 and 2 (P = 0.50), 4 and 12 (P = 0.005), and 11 and 24 (P = 0.001), respectively. CONCLUSION Aggressive initial treatment of early RA with the combination of 3 DMARDs for the first 2 years limits the peripheral joint damage for at least 5 years. Our results confirm the earlier concept that triple therapy with combinations of DMARDs contributes to an improved long-term radiologic outcome in patients with early and clinically active RA.

Abstract
OBJECTIVE To investigate at 5 years whether an initial 2 year home based strength training period imposes sustained effects on muscle strength, bone mineral density (BMD), structural joint damage, and on disease activity in patients with early rheumatoid arthritis (RA). METHODS Seventy patients were randomised either to perform home based strength training with loads of 50-70% of repetition maximum (EG) or range of motion exercises (CG). Both groups were encouraged to take part in aerobic activities 2-3 times a week. Maximal muscle strength of different muscle groups was measured by dynamometers, and BMD at the femoral neck and lumbar spine by dual x ray densitometry. Disease activity was assessed by the 28 joint disease activity score, and joint damage by x ray findings. RESULTS 62 patients completed 2 years' training and 59 patients attended check up at 5 years. Mean (SD) maximum muscle strength indices increased from baseline to 2 years-in EG from 212 (78) kg by a mean (95% CI) of 68 (55 to 80) and in CG from 195 (72) kg by 35 (13 to 60) kg-and remained at that level for the next 3 years. Development of BMD in EG tended to be more favourable than that in CG. Muscle strength training was not detrimental to joint structures or disease activity. CONCLUSION The patients' exercise induced muscle strength gains during a 2 year training period were maintained throughout a subsequent self monitored training period of 3 years. Despite substantial training effects in muscle strength, BMD values remained relatively constant. Radiographic damage remained low even at 5 years.

Abstract
BACKGROUND The self report health assessment questionnaire (HAQ) quantifies disability in activities of daily living (ADL). In patients with rheumatoid arthritis, the HAQ predicts mortality, work disability, and hip replacement surgery. It has been widely used in rheumatology, but population based data are rare. OBJECTIVE To determine whether the HAQ predicts mortality in patients with rheumatoid arthritis (n = 1095) and community controls (n = 1490). METHODS A mailed questionnaire including the HAQ, visual analogue scales for pain and global health, comorbidities, education level, height, weight, and smoking status was administered in June 2000. Two years later, the vital status of the subjects was ascertained from the Finnish Population Register database. RESULTS There were 41 deaths (10.1%) among the 404 patients with rheumatoid arthritis who had a baseline HAQ > or =1 (indicating at least some difficulty in most ADL), and 16 (2.3%) among 691 patients with HAQ <1 (p<0.001); in the community controls the values were 20 (13.6%) among 147 with HAQ > or =1, and 14 (1.0%) among 1343 with HAQ <1 (p<0.001). A higher HAQ score was an independent predictor of mortality in patients with rheumatoid arthritis (hazard ratio 2.73 (95% confidence interval, 1.86 to 4.02); p<0.001) and in community controls (2.75 (1.61 to 4.70); p<0.001). CONCLUSIONS The HAQ predicts mortality in the community population as well as in patients with rheumatoid arthritis. People with similar levels of disability appear to have a similar likelihood of mortality over two years.

Abstract
OBJECTIVE There is a common impression, rarely documented, that the outlook of patients with rheumatoid arthritis (RA) is different today compared to previous decades. We investigated the 5-year radiographic progression of 3 cohorts of patients with early RA enrolled in the 1980s and 1990s. METHODS Patients with early RA were enrolled into 3 separate studies in 1983-85 (n = 58; Cohort A), 1988-89 (n = 77; Cohort B), and 1995-96 (n = 62; Cohort C) at one rheumatology center; all were subsequently treated actively with disease-modifying antirheumatic drugs according to the "sawtooth strategy" to control inflammation, and monitored regularly to collect data for evaluation of longterm outcome. Evaluation over 5 years included disease activity measures and medications. Radiographs of hands and feet taken at baseline and at 2 and 5 years were analyzed by Larsen score (0-100). RESULTS Larsen score increased by a median of 12, 6, and 4 points by Year 5 in cohorts A, B, and C, respectively (p = 0.001), adjusted for age, sex, rheumatoid factor (+/-), and the baseline values for Larsen score and erythrocyte sedimentation rate. RF positivity and persistent high disease activity over 5 years were associated with greater progression of radiographic damage. CONCLUSION Radiographic progression was greatest in the earliest cohort and mildest in the most recent cohort, a phenomenon that was also seen in the literature review. The reasons for the observation may include (1) improved therapy, (2) milder disease, and (3) patient selection.

Abstract
OBJECTIVE To explore the associations between individual subdimensions of the health assessment questionnaire (HAQ) and clinical variables in patients with rheumatoid arthritis. METHODS 304 patients with rheumatoid arthritis (73% female, mean (SD) age, 58 (13) years; disease duration 6 (9) years, 69% rheumatoid factor positive) completed the HAQ for functional capacity (0-3) and a 100 mm visual analogue scale for pain. Grip strength, range of motion of the large joints, Larsen score for radiographic damage of hand and foot joints, and the number of tender and swollen joints were recorded. A logit regression model was used to study associations between subdimensions of the HAQ and other variables. RESULTS Mean (range) total HAQ score was 0.92 (0 to 2.88) and varied from 0.73 to 1.04 in the subdimensions. Disability was lowest in the "walking" and highest in the "reach" subdimension. Pain was an explanatory variable in all individual subdimensions. Decreased grip strength, limitation of shoulder and wrist motion, and a larger number of swollen and tender joints in the upper extremities were related to several subdimensions. A higher pain score and swollen joint count in the upper extremities, decreased grip strength, and limited motion of wrist, shoulder, and knee joints explained increased disability (higher total HAQ scores). CONCLUSIONS In patients with rheumatoid arthritis, pain and range of movements of joints have the greatest impact on individual subdimensions of the HAQ. Extent of radiographic damage in peripheral joints and the number of swollen and tender joints are of lesser importance for function.

Abstract
OBJECTIVE To evaluate the impact of a 2-year home-based strength-training program on physical function in patients with early rheumatoid arthritis (RA) after a subsequent 3-year followup. METHODS Seventy patients with early RA were randomized to perform either strength training (experimental group [EG]) or range-of-motion exercises (control group [CG]). Maximal strength values were recorded by dynamometers. The Modified Disease Activity Score (DAS28), pain, Health Assessment Questionnaire (HAQ), walking speed, and stair-climbing speed were also measured. RESULTS The maximum strength of assessed muscle groups increased by 19-59% in the EG during the training period and remained at the reached level throughout the subsequent 3 years. Muscle strength improved in the CG by 1-31%, but less compared with the EG. During the 2-year training period, DAS28 decreased by 50% and 45% and pain by 67% and 39% in the EG and CG, respectively. The differences in muscle strength, DAS28, and HAQ were significantly in favor of the EG both at the 2-year and 5-year followup assessments. CONCLUSIONS The improvements achieved during the 2-year strength-training period were sustained for 3 years in patients with early RA.

Abstract
OBJECTIVE The Health Assessment Questionnaire (HAQ) disability index (DI) has been commonly used in rheumatology to quantify functional disability in patient groups, but current general population values of this index are not available. This study was undertaken to establish normative values for the HAQ DI in a general population and to analyze its correlates. METHODS The HAQ DI (range of scores 0-3) was measured in a random sample of 1,530 adults in the Central Finland District. Prevalence rates of disability by strata of age, sex, education level, body mass index (BMI), and health behaviors (including smoking and exercise habits) were calculated. Pearson's product-moment correlation coefficient and ordinary least squares regression were used to analyze the data. RESULTS The estimated population mean HAQ DI was 0.25 (95% confidence interval 0.22-0.28), and 32% of respondents had at least some disability. Both for men and for women, functional disability increased exponentially with age. The HAQ DI was correlated with pain (r = 0.58) and global self assessment (r = 0.61). The prevalence of disability decreased with increasing number of years of education, lower BMI, and increasing frequency of physical exercise. CONCLUSION Almost one-third of the general population has some functional disability. Functional disability is associated in part with lifestyle choices and increases with age in a nonlinear manner. The normative values of the HAQ DI that we have presented could be used as a reference benchmark for clinical and epidemiologic studies using this measure of disability.

Abstract
OBJECTIVE To investigate the effects of strength training on neuromuscular functions in elderly females with fibromyalgia (FM). METHODS Thirteen females with fibromyalgia [group FMt; mean age (s.d.) 60.2 (2.5) years] and 11 healthy controls [group HCt; 64.2 (2.7) yr] carried out supervised strength training twice a week for 21 weeks. Thirteen FM patients [group FMc; 59.1 (3.5) yr] served as non-training controls. Maximal isometric force and electromyographic (EMG) activity of the right quadriceps femoris in knee extension and flexion actions, maximal 10-m walking speed, and 10-step stair-climbing time were measured. Tender points were assessed by palpation, subjectively perceived symptoms with a visual analogue scale, and the self-reported physical function capacity by Health Assessment Questionnaire (HAQ). RESULTS The mean (s.d.) increases in maximal extension force during the training period in groups FMt and in HCt were 32 (33)% (P < 0.001) and 24 (12)% (P < 0.001) respectively and those of flexion were 13 (20)% (P < 0.05) and 24 (17)% (P < 0.01). Explosive force of the extensors increased in both FMt and in HCt. The integrated EMGs of the vastus lateralis and medialis muscles increased in both FMt and HCt. Muscle forces and EMGs in group FMc remained at the basal level. Walking speed, stair-climbing time and the HAQ index improved in group FMt. The changes in the number of tender points and in perceived symptoms were in favour of the training group FMt. CONCLUSIONS The data support the hypothesis that elderly female FM patients have normal neuromuscular function. Supervised strength training also suits elderly FM patients, has positive effects on perceived symptoms and improves functional capacity without complications.

Abstract
OBJECTIVE To compare the efficacy of therapy with a combination of disease-modifying antirheumatic drugs (DMARDs) versus therapy with a single DMARD in the prevention of work disability in patients with early rheumatoid arthritis (RA). METHODS In the Finnish Rheumatoid Arthritis Combination Therapy trial, 195 patients with recent-onset RA were randomly assigned to receive either combination therapy with DMARDs (sulfasalazine, methotrexate, hydroxychloroquine) plus prednisolone or single therapy with a DMARD with or without prednisolone. After 2 years, the drug treatment strategy was no longer restricted. At baseline, 162 patients (80 in the combination-treatment group and 82 in the single-treatment group) were still working or at least available for work. After 5 years of followup, data on all sick leave and retirement were obtained from social insurance registers or case records. The main outcome for each patient was the cumulative duration of all sick leaves and RA-related disability pensions, divided by the observation period during which the patient was not retired because of another disease or because of age. RESULTS The cumulative duration of work disability per patient-observation year was significantly lower in those randomized to combination therapy than in those randomized to single therapy: median 12.4 days (interquartile range [IQR] 0-54) versus 32.2 days (IQR 6-293) (P = 0.008, sex- and age-adjusted P = 0.009). This was mainly due to the difference in sick leaves (i.e., work disability periods </=300 days): median 11.7 days (IQR 0-44) per patient-observation year in those treated with combination therapy and 30.0 days (IQR 6-68) in those treated with single therapy (P = 0.002). No statistically significant difference was seen in RA-related disability pensions. CONCLUSION Aggressive initial treatment of RA with a combination of DMARDs improves 5-year outcome in terms of lost productivity in patients with RA of recent onset.
