Abstract
BACKGROUND Rheumatoid arthritis (RA) is often preceded by symptomatic phases during which classification criteria are not fulfilled. The health burden of these "at-risk" stages is not well described. This study assessed health-related quality of life (HRQoL), function, fatigue and depression in newly presenting patients with clinically suspect arthralgia (CSA), unclassified arthritis (UA) or RA. METHODS Cross-sectional analysis of baseline Patient-Reported Outcome Measures (PROMs) was conducted in patients from the Birmingham Early Arthritis Cohort. HRQoL, function, depression and fatigue at presentation were assessed using EQ-5D, HAQ-DI, PHQ-9 and FACIT-F. PROMs were compared across CSA, UA and RA and with population averages from the HSE with descriptive statistics. Multivariate linear regression assessed associations between PROMs and clinical and sociodemographic variables. RESULTS Of 838 patients included in the analysis, 484 had RA, 200 had CSA and 154 had UA. Patients with RA reported worse outcomes for all PROMs than those with CSA or UA. However, "mean EQ-5D utilities were 0.65 (95%CI: 0.61 to 0.69) in CSA, 0.61 (0.56 to 0.66) in UA and 0.47 (0.44 to 0.50) in RA, which was lower than in general and older (≥ 65 years) background populations." In patients with CSA or UA, HRQoL was comparable to chronic conditions such as heart failure, severe COPD or mild angina. Higher BMI and older age (≥ 60 years) predicted worse depression (PHQ-9: -2.47 (-3.85 to -1.09), P < 0.001) and fatigue (FACIT-F: 5.05 (2.37 to 7.73), P < 0.001). Women were more likely to report worse function (HAQ-DI: 0.13 (0.03 to 0.21), P = 0.01) and fatigue (FACIT-F: -3.64 (-5.59 to -1.70), P < 0.001), and residents of more deprived areas experienced decreased function (HAQ-DI: 0.23 (0.10 to 0.36), P = 0.001), greater depression (PHQ-9: 1.89 (0.59 to 3.18), P = 0.004) and fatigue (FACIT-F: -2.60 (-5.11 to 0.09), P = 0.04). After adjustments for confounding factors, diagnostic category was not associated with PROMs, but disease activity and polypharmacy were associated with poorer performance across all PROMs. CONCLUSIONS Patient-reported outcomes were associated with disease activity and sociodemographic characteristics. Patients presenting with RA reported a higher health burden than those with CSA or UA, however HRQoL in the pre-RA groups was significantly lower than population averages.

Abstract
AIM Periodontitis is independently associated with rheumatoid arthritis (RA); however, there is limited data on whether periodontal treatment improves overall RA disease activity. We conducted a pilot feasibility randomized controlled clinical trial to test whether intensive periodontal therapy reduces RA disease activity in patients with active RA and periodontitis. MATERIALS AND METHODS The following inclusion criteria were applied: patients with RA and periodontitis, aged 18+, stable on treatment with disease-modifying anti-rheumatic drugs for ≥3 months, disease activity score (DAS28) ≥3.2, and DAS28 >5.1 only if patient unwilling to take biologics. Participants meeting the inclusion criteria were randomized to immediate intensive periodontal therapy or to delayed therapy (control group) administered by a dental hygienist in a secondary care setting. Data were collected at baseline and at 3 and 6 months of follow-up. Participants randomized to the control group (delayed therapy) received the standard of care for the duration of the trial, including oral hygiene instructions delivered by a dental hygienist, and the same periodontal therapy as the intervention group after study completion (i.e., 6 months after randomization). The periodontal inflammation surface area was calculated using clinical attachment loss (CAL), periodontal probing pocket depth, and bleeding on probing. Cumulative probing depth was also measured. We examined the effect of periodontal therapy on periodontal outcomes and on clinical markers of disease activity in RA, as measured by the DAS28-C-reactive protein score as well as musculo-skeletal ultrasound grey scale and power Doppler scores. RESULTS A total of 649 patients with RA were invited to participate in the study. Of these, 296 (46%) consented to participate in the screening visit. A sample of 201 patients was assessed for eligibility, of whom 41 (20%) did not meet the RA inclusion criteria and 100 (50%) did not meet the periodontal disease criteria. Among the 60 (30%) eligible participants, 30 were randomized to immediate periodontal therapy and 30 were allocated to the control group. The loss to follow-up was 18% at the end of the trial. There were no major differences with regard to baseline characteristics between the groups. Periodontal therapy was associated with reduced periodontal inflamed surface area, cumulative probing depths, RA disease activity scores, and ultrasound scores over the course of the trial. There was no change in CAL. CONCLUSIONS Overall, the trial was feasible and acceptable to the study participants. Recruitment to and satisfactory retention in a randomized controlled trial on the effect of periodontal treatment on RA patients is possible, albeit challenging. In this feasibility study of patients with RA and periodontitis, periodontal treatment resulted in significant improvements in periodontal disease outcomes and overall RA disease activity, although complete resolution of periodontal inflammation was difficult to achieve in some cases.

Abstract
OBJECTIVE To estimate and compare the diagnostic accuracy of magnetic resonance imaging (MRI) and ultrasound, for the prediction of rheumatoid arthritis (RA) in unclassified arthritis (UA). METHODS MEDLINE, Embase and BIOSIS were searched from 1987 to May 2019. Studies evaluating any imaging test in participants with UA were eligible. Reference standards were RA classification criteria or methotrexate initiation. Two authors independently extracted data and assessed validity using QUADAS-2. Sensitivities and specificities were calculated for each imaging characteristic and joint area. Summary estimates with 95% confidence intervals (CI) were estimated where possible. RESULTS Nineteen studies were included; 13 evaluated MRI (n=1,143; 454 with RA) and 6 evaluated ultrasound (n=531; 205 with RA). Studies were limited by unclear recruitment procedures, inclusion of patients with RA at baseline, differential verification, lack of blinding and consensus grading. Study heterogeneity largely precluded meta-analysis, however summary sensitivity and specificity for MRI synovitis in at least one joint were 93% (95% CI 88%, 96%) and 25% (95% CI 13%, 41%) (3 studies). Specificities may be higher for other MRI characteristics but data are limited. Ultrasound results were difficult to synthesise due to different diagnostic thresholds and reference standards. CONCLUSION The evidence for MRI or ultrasound as single tests for predicting RA in people with UA is heterogeneous and of variable methodological quality. Larger studies using consensus grading and consistently defined RA diagnosis are needed to identify whether combinations of imaging characteristics, either alone or in combination with other clinical findings, can better predict RA in this population.

Abstract
OBJECTIVE To analyze the effect of tooth loss/periodontitis on disease activity in early and established rheumatoid arthritis (RA). METHODS Participants of the Course And Prognosis of Early Arthritis (CAPEA) early arthritis cohort reported their number of teeth at baseline. The number of teeth had been validated as a predictor of periodontitis. Clinical end points, including disease activity score (Disease Activity Score in 28 joints using the erythrocyte sedimentation rate [ESR]), swollen joint count (SJC), ESR, and C-reactive protein level were collected at baseline, 3, 6, 12, 18, and 24 months. We used linear mixed regression models to estimate the association between tooth loss and clinical end points over time in early arthritis. For established RA, we analyzed cross-sectional data from the German National Database (NDB). All models accounted for age, sex, smoking, seropositivity, education level, and disease duration (only NDB). RESULTS Among 1,124 CAPEA participants with early arthritis, those with higher tooth loss were older, more often male, smokers, and seropositive, and they had higher disease activity and inflammation markers at baseline. Tooth loss was associated with higher disease activity and ESR values over time. Inflammatory markers decreased comparably across tooth loss categories. Glucocorticoid use was higher among those with more tooth loss, whereas dose reduction was similar across tooth loss categories. Among 7,179 NDB participants with longstanding RA, disease activity and inflammation markers but not SJC were significantly higher in patients with more tooth loss. CONCLUSION Although we observed an association between tooth loss and disease activity scores and inflammation markers in early and established RA, longitudinal results suggest that tooth loss does not hamper treatment response.

Abstract
OBJECTIVES Non-genetic risk factors for Sjögren's syndrome (SS) are poorly understood. Adherence to a Mediterranean diet has been associated with reduction in other autoimmune diseases. We examined the association of Mediterranean diet with SS. METHODS New patients attending a single centre warranting investigation for primary SS (pSS) were recruited into the Optimising Assessment in Sjögren's Syndrome cohort established in Birmingham, UK (2014-2018). Participants were classified into pSS and non-SS sicca, considered as cases and non-cases, respectively, and asked to complete an optional food frequency questionnaire on their diet before onset of symptoms. A semi-quantitative Mediterranean diet score (MDS) was calculated (possible range=0 to 18). Using multivariate logistic regression, corrected for energy intake, body-mass index, sex, age, symptom duration, and smoking status, we examined the association of MDS with SS. RESULTS Dietary data were available for 133/243 (55%) eligible patients (n=82 pSS and n=51 sicca). In the adjusted model, a higher total MDS (mean ± SD, 9.41±2.31 points) was associated with lower odds of pSS (OR 0.81, 95% CI 0.66-0.99; p=0.038) per one unit of MDS. Among MDS components, the strongest association was seen with fish with OR 0.44 (95% CI 0.24-0.83; p=0.01) in the comparison between <1 portion/week and 1 to 2.5 portions/week. Higher galactose, vitamin A-retinol-equivalents and vitamin C showed associations with lower odds of pSS in multivariate analysis, where the association of vitamin C was attenuated when adjusted for MDS. CONCLUSIONS When adjusted for potential confounders, adherence to the Mediterranean diet was associated with lower likelihood of having pSS.

Abstract
Rheumatoid arthritis (RA) and chronic periodontitis are common chronic inflammatory diseases that share numerous clinical and pathobiological characteristics. Due to their similarities, despite manifesting at anatomically distinct sites, the relationship between these two diseases has been investigated for many years. This review attempts to summarise the state of the field based on evidence published in the last ten years.

Abstract
Rheumatoid arthritis (RA) and periodontitis (PD) are inflammatory diseases characterised by an exacerbated immune-inflammatory reaction that leads to the destruction of bone and other connective tissues that share numerous similarities. Although a significant and independent association between these two conditions has been described, the pathophysiological processes that may explain this relationship remain unknown and multiple theories have been proposed. This review presents the most important theories currently proposed to explain the biological link between RA and PD.

Abstract
OBJECTIVES Tenosynovitis (TS) is common in early arthritis. However, the value of US-defined TS in predicting RA development is unclear. We assessed the predictive utility of US-defined TS alongside US-defined synovitis and clinical and serological variables in a prospective cohort of early arthritis patients. METHODS One hundred and seven patients with clinically apparent synovitis of one or more joint and symptom duration ⩽3 months underwent baseline clinical, laboratory and US assessment of 19 bilateral joint sites and 16 bilateral tendon compartments. Diagnostic outcome was determined after 18 months, applying the 2010 ACR/EULAR classification criteria for RA. The predictive values of US-defined TS for persistent RA were compared with those of US-defined synovitis, clinical and serological variables. RESULTS A total of 4066 US joint sites and 3424 US tendon compartments were included in the analysis. Forty-six patients developed persistent RA, 17 patients developed non-RA persistent disease and 44 patients had resolving disease at follow-up. US-defined TS in at least one tendon compartment at baseline was common in all groups (RA 85%, non-RA persistent disease 71% and resolving 70%). On multi-variate analysis, US-defined digit flexor TS provided independent predictive data over and above the presence of ACPA and US-defined joint synovitis. CONCLUSION US-defined digit flexor TS provided independent predictive data for persistent RA development in patients with early arthritis. The predictive utility of this tendon site should be further assessed in a larger cohort; investigators designing imaging-based predictive algorithms for RA development should include this tendon component as a candidate variable.

Abstract
OBJECTIVE Studies that demonstrate an association between rheumatoid arthritis (RA) and dysbiotic oral microbiomes are often confounded by the presence of extensive periodontitis in these individuals. This study was undertaken to investigate the role of RA in modulating the periodontal microbiome by comparing periodontally healthy individuals with RA to those without RA. METHODS Subgingival plaque was collected from periodontally healthy individuals (22 with RA and 19 without RA), and the 16S gene was sequenced on an Illumina MiSeq platform. Bacterial biodiversity and co-occurrence patterns were examined using the QIIME and PhyloToAST pipelines. RESULTS The subgingival microbiomes differed significantly between patients with RA and controls based on both community membership and the abundance of lineages, with 41.9% of the community differing in abundance and 19% in membership. In contrast to the sparse and predominantly congeneric co-occurrence networks seen in controls, RA patients revealed a highly connected grid containing a large intergeneric hub anchored by known periodontal pathogens. Predictive metagenomic analysis (PICRUSt) demonstrated that arachidonic acid and ester lipid metabolism pathways might partly explain the robustness of this clustering. As expected from a periodontally healthy cohort, Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans were not significantly different between groups; however, Cryptobacterium curtum, another organism capable of producing large amounts of citrulline, emerged as a robust discriminant of the microbiome in individuals with RA. CONCLUSION Our data demonstrate that the oral microbiome in RA is enriched for inflammophilic and citrulline-producing organisms, which may play a role in the production of autoantigenic citrullinated peptides in RA.

Abstract
ObjectivesFindings relating to dietary intake of n-3 polyunsaturated fatty acids (PUFA) and risk of rheumatoid arthritis (RA) are mixed. Erythrocyte membrane PUFA is an accurate objective biomarker of PUFA status; however, there are little data on erythrocyte membrane PUFA and risk of RA. The objective was therefore to compare erythrocyte membrane PUFA between pre-RA individuals and matched controls from a population-based sample, and specifically to test the hypothesis that higher levels of longer chain n-3 PUFA are associated with lower risk of RA.MethodsThe European Prospective Investigation into Cancer and Nutrition (EPIC) is a large European prospective cohort study of apparently healthy populations. We undertook a nested case–control study by identifying RA cases with onset after enrolment (pre-RA) in four EPIC cohorts in Italy and Spain. Confirmed pre-RA cases were matched with controls by age, sex, centre, and date, time and fasting status at blood collection. Conditional logistic regression analysis was used to estimate associations of PUFA with the development of RA, adjusting for potential confounders including body mass index, waist circumference, education level, physical activity, smoking status and alcohol intake.ResultsThe study analysed samples from 96 pre-RA subjects and 258 matched controls. In this analysis, the median time to diagnosis (defined as time between date of blood sample and date of diagnosis) was 6.71 years (range 0.8–15). A significant inverse association was observed with n-6 PUFA linoleic acid (LA) levels and pre-RA in the fully adjusted model (highest tertile: OR 0.29; 95% CI 0.12 to 0.75; P for trend 0.01). No association was observed with any individual n-3 PUFA, total n-3 PUFA or total n-3:n-6 ratio.ConclusionsErythrocyte levels of the n-6 PUFA LA were inversely associated with risk of RA, whereas no associations were observed for other n-6 or n-3 PUFA. Further work is warranted to replicate these findings and to investigate if lower LA levels are a bystander or contributor to the process of RA development.

Abstract
AIMS The aims of this study were as follows: (i) To assess the prevalence of periodontitis among patients with primary Sjögren's syndrome (pSS) and comparator groups of patients with rheumatoid arthritis (RA) and osteoarthritis (OA). (ii) To perform a pilot study to compare serum antibody responses to 10 oral/periodontal bacteria in these patient groups and a historical comparator group of patients with periodontitis. MATERIALS AND METHODS Standard clinical periodontal assessments were performed on 39 pSS, 36 RA and 23 OA patients and "In-house" antibody ELISAs for serum antibodies against 10 oral/periodontal bacteria were performed in these groups. RESULTS Forty-six percent of the pSS group, 64% of the RA group and 48% of the OA group had moderate/severe periodontitis. These frequencies did not reach statistical significance between groups. Raised antibody levels to Prevotella denticola were found in the pSS, RA and periodontitis groups compared to the OA group. Significant between group differences were seen for Aggregatibacter actinomycetemcomitans, Prevotella intermedia and Campylobacter showae. None of these differences were specifically associated with pSS. CONCLUSION This study showed no increase in periodontitis in pSS patients. Although the P. denticola data are of interest, identifying bacterial triggering factors for pSS will likely require alternative strategies including modern techniques such as microbiome analysis.

Abstract
Background Antibodies to citrullinated proteins (ACPA) occur years before RA diagnosis. Porphyromonas gingivalis expresses its own peptidylarginine deiminase (PPAD), and is a proposed aetiological factor for the ACPA response. Smoking is a risk factor for both ACPA-positive RA and periodontitis. We aimed to study the relation of these factors to the risk of RA in a prospective cohort. Methods We performed a nested case–control study by identifying pre-RA cases in four populations from the European Prospective Investigation into Cancer and nutrition, matched with three controls. Data on smoking and other covariates were obtained from baseline questionnaires. Antibodies to CCP2 and citrullinated peptides from α-enolase, fibrinogen, vimentin and PPAD were measured. Antibodies to arginine gingipain (RgpB) were used as a marker for P.gingivalis infection and validated in a separate cohort of healthy controls and subjects with periodontitis. Results We studied 103 pre-RA cases. RA development was associated with several ACPA specificities, but not with antibodies to citrullinated PPAD peptides. Antibody levels to RgpB and PPAD peptides were higher in smokers but were not associated with risk of RA or with pre-RA autoimmunity. Former but not current smoking was associated with antibodies to α-enolase (OR 4.06; 95 % CI 1.02, 16.2 versus 0.54; 0.09-3.73) and fibrinogen peptides (OR 4.24; 95 % CI 1.2-14.96 versus 0.58; 0.13-2.70), and later development of RA (OR 2.48; 95 % CI 1.27-4.84 versus 1.57; 0.85-2.93), independent of smoking intensity. Conclusions Smoking remains a risk factor for RA well before the clinical onset of disease. In this cohort, P.gingivalis is not associated with pre-RA autoimmunity or risk of RA in an early phase before disease-onset. Antibodies to PPAD peptides are not an early feature of ACPA ontogeny.

Abstract
OBJECTIVES To examine the diagnostic outcomes associated with clinical ankle synovitis in an early inflammatory arthritis cohort. METHODS Data from the Birmingham early inflammatory arthritis cohort (BEACON) were used to obtain information about baseline disease and demographic variables and diagnostic outcomes at 18 month follow-up. The prevalence of clinical ankle synovitis (defined as joint swelling on examination) was calculated. Relative risk (RR) and 95% confidence interval (95% CI) were used to estimate whether clinical ankle synovitis at baseline predicts diagnostic outcomes independent of age, sex, baseline 66-joint swollen joint count, and presence of either rheumatoid factor (RF) or anti-CCP antibody. RESULTS 324 patients (52% women) were included. 103 had clinical ankle synovitis at the first clinic visit. Patients with bilateral ankle synovitis were more likely to be classified as having acute sarcoid arthritis (aRR (95%CI) 10.15 (1.13-90.89)). Among patients presenting with oligoarthritis and seronegative for RF and anti-CCP antibodies those with ankle synovitis were significantly more likely to be classified as having seronegative spondyloarthritis (RR (95%CI) 6.15 (1.58-23.88) and unclassified arthritis (RR (95%CI) 4.07 (1.05-15.81)) than RA. CONCLUSIONS Current predictive algorithms for patients with early arthritis focus on the prediction of RA or persistent arthritis. This alternative approach focused on a specific joint shows that baseline ankle synovitis predicts specific diagnostic outcomes besides RA. Future work should address the development of models to predict the totality of potential outcomes based on clinical phenotype and the results of routinely available investigations and clinical data.

Abstract
BACKGROUND Studies suggest that periodontitis may be a risk factor for rheumatoid arthritis (RA). The purpose of this study was to determine whether periodontitis is associated with autoantibodies characteristic of RA. METHODS Serum samples were tested for anti-cyclic citrullinated peptide (CCP), anti-mutated citrullinated vimentin (MCV), anti-citrullinated α-enolase peptide-1 (CEP-1), anti-citrullinated vimentin (cit-vim), anti-citrullinated fibrinogen (cit-fib) and their uncitrullinated forms anti-CParg (negative control for anti-CCP), anti-arginine-containing α-enolase peptide-1 (REP-1), anti-vimentin and anti-fibrinogen antibodies in patients with and without periodontitis, none of whom had RA. RESULTS Periodontitis, compared with non-periodontitis, was associated with a normal frequency of anti-CCP and anti-MCV (∼1%) but a higher frequency of positive anti-CEP-1 (12% vs 3%; p=0.02) and its uncitrullinated form anti-REP-1 (16% vs 2%; p<0.001). Positive antibodies against uncitrullinated fibrinogen and CParg were also more common among those with periodontitis compared to non-periodontitis patients (26% vs 3%; p<0.001, and 9% vs 3%; p=0.06). After adjusting for confounders, patients with periodontitis had 43% (p=0.03), 71% (p=0.002) and 114% (p<0.001) higher anti-CEP-1, anti-REP-1 and anti-fibrinogen titres, compared with non-periodontitis. Non-smokers with periodontitis, compared with non-periodontitis, had significantly higher titres of anti-CEP-1 (103%, p<0.001), anti-REP-1 (91%, p=0.001), anti-vimentin (87%, p=0.002), and anti-fibrinogen (124%, p<0.001), independent of confounders, confirming that the autoantibody response in periodontitis was not due to smoking. CONCLUSIONS We have shown that the antibody response in periodontitis is predominantly directed to the uncitrullinated peptides of the RA autoantigens examined in this study. We propose that this loss of tolerance could then lead to epitope spreading to citrullinated epitopes as the autoimmune response in periodontitis evolves into that of presymptomatic RA.

Abstract
OBJECTIVE Several studies suggest that bone mineral density (BMD) is reduced in chronic inflammatory diseases. Higher serum levels of C-reactive protein (CRP) have been associated with lower BMD in women and older adults. However, it is not clear whether this association holds in a representative sample of the general population. The purpose of this study was to examine the relationship between BMD and CRP level in a large representative US population-based sample from the National Health and Nutrition Examination Survey (NHANES). METHODS We included participants age ≥20 years with BMD (total and subregions) measured by dual x-ray absorptiometry scans and complete information on covariates from NHANES. The association between CRP level and BMD was evaluated using multivariate linear regression models, adjusting for potential confounders and further adjusting for comorbid diseases, medications, and serum vitamin D levels. RESULTS The study sample included 10,475 participants (53% Caucasian, 22% Mexican American, 18% African American, and 7% other races). Men had higher BMD and lower CRP concentrations than women. BMD (total body BMD as well as subtotal BMD and BMD of the extremities, ribs, and trunk subregions) was inversely associated with quintiles of CRP concentration both in men and in women in a dose-dependent manner (for total BMD, P for trend < 0.0001 for men, P for trend = 0.0005 for women). The associations were independent of medications, comorbidities, and other potential confounders. The results remained largely unchanged with further adjustment for serum vitamin D levels. CONCLUSION Among men and women in a large representative population-based sample, the CRP level was inversely and independently associated with total BMD in a dose-dependent manner.

The 2010 American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR) classification criteria, which replace the 1987 classification criteria, have been developed to facilitate such identification in patients with newly presenting inflammatory arthritis. This study therefore assesses the performance of these new criteria in patients with early synovitis.MethodsData were analysed from patients with synovitis seen within 3 months of the onset of inflammatory arthritis. Patients were followed for 18 months to determine outcomes, and data on the cumulative fulfilment of 2010 and 1987 criteria and therapy were recorded.Results265 patients were included in the study. 60 had alternative diagnoses at baseline. Of the remaining 205 patients, 20% fulfilled both 1987 and 2010 criteria, 3% fulfilled only 1987 criteria and 22% fulfilled only 2010 criteria at baseline. The 2010 criteria, when applied at baseline, detected more patients who eventually required disease-modifying antirheumatic drugs (DMARD) (65 (62%) vs 40 (38%); p<0.001), especially methotrexate (50 (68%) vs 31 (42%); p<0.01), within the first 18 months. However, more patients whose disease eventually resolved without ever requiring DMARD were classified at baseline as RA according to the 2010 criteria than with the 1987 criteria (16 (8%) vs 5 (2%); p=0.01).ConclusionThe 2010 ACR/EULAR criteria allow more rapid identification of patients requiring methotrexate compared with the 1987 ACR criteria when applied at baseline. However, overdiagnosis is an important issue to consider if these criteria are to be used in very early disease.

Abstract
OBJECTIVES Early therapy improves outcomes in rheumatoid arthritis (RA). It is therefore important to improve predictive algorithms for RA in early disease. This study evaluated musculoskeletal ultrasound, a sensitive tool for the detection of synovitis and erosions, as a predictor of outcome in very early synovitis. METHODS 58 patients with clinically apparent synovitis of at least one joint and symptom duration of ≤3 months underwent clinical, laboratory, radiographic and 38 joint ultrasound assessments and were followed prospectively for 18 months, determining outcome by 1987 American College of Rheumatology (ACR) and 2010 ACR/European League Against Rheumatism criteria. Sensitivity and specificity for 1987 RA criteria were determined for ultrasound variables and logistic regression models were then fitted to evaluate predictive ability over and above the Leiden rule. RESULTS 16 patients resolved, 13 developed non-RA persistent disease and 29 developed RA by 1987 criteria. Ultrasound demonstrated subclinical wrist, elbow, knee, ankle and metatarsophalangeal joint involvement in patients developing RA. Large joint and proximal interphalangeal joint ultrasound variables had poor predictive ability, whereas ultrasound erosions lacked specificity. Regression analysis demonstrated that greyscale wrist and metacarpophalangeal joint involvement, and power Doppler involvement of metatarsophalangeal joints provided independently predictive data. Global ultrasound counts were inferior to minimal power Doppler counts, which significantly improved area under the curve values from 0.905 to 0.962 combined with the Leiden rule. CONCLUSION In a longitudinal study, extended ultrasound joint evaluation significantly increased detection of joint involvement in all regions and outcome groups. Greyscale and power Doppler scanning of metacarpophalangeal joints, wrists and metatarsophalangeal joints provides the optimum minimal ultrasound data to improve on clinical predictive models for RA.

Abstract
Periodontitis is a chronic inflammatory disease that is characterized by loss of the periodontal ligament and alveolar bone, and is a major cause of tooth loss. Results from clinical and epidemiologic studies have suggested that periodontitis and tooth loss are more prevalent in individuals with rheumatoid arthritis (RA). However, the strength and temporality of the association are uncertain. Several biologically plausible causal and noncausal mechanisms might account for this association between periodontitis and RA. There is evidence to suggest that periodontitis could indeed be a causal factor in the initiation and maintenance of the autoimmune inflammatory response that occurs in RA. If proven, chronic periodontitis might represent an important modifiable risk factor for RA. In addition, patients with RA might show an increased risk of developing periodontitis and tooth loss through various mechanisms. Moreover, exposure to common genetic, environmental or behavioral factors might contribute to a noncausal association between both conditions.

Abstract
OBJECTIVE To test for an association of periodontitis and tooth loss with rheumatoid arthritis (RA). METHODS The third National Health and Nutrition Examination Survey (NHANES III) is a nationally representative cross-sectional survey of noninstitutionalized civilians. We included participants aged > or = 60 years who had undergone both musculoskeletal and dental examinations. RA was defined based on American College of Rheumatology criteria. Dental examinations quantified decayed and filled surfaces, missing teeth, and periodontitis. Periodontitis was defined as at least 1 site exhibiting both attachment loss and a probing depth of > or = 4 mm. We classified dental health status as (1) no periodontitis, (2) periodontitis, or (3) edentulous (i.e., complete tooth loss). We performed multivariate multinomial logistic regression models with dental health status as the dependent and RA as the independent variables. RESULTS The sample consisted of 4461 participants, of whom 103 were classified as having RA. Participants with RA had more missing teeth (20 vs 16 teeth; p < 0.001), but less decay (2% vs 4%; p < 0.001) than participants without RA. After adjusting for age, sex, race/ethnicity, and smoking, subjects with RA were more likely to be edentulous [odds ratio (OR) 2.27, 95% confidence interval (CI) 1.56 3.31] and have periodontitis (OR 1.82, 95% CI 1.04 3.20) compared with non-RA subjects. In participants with seropositive RA there was a stronger association with dental health status, in particular with edentulism (OR 4.5, 95% CI 1.2 17). CONCLUSION RA may be associated with tooth loss and periodontitis.

Abstract
OBJECTIVE To estimate the extent of radiographic and orthopedic followup among recipients of total hip replacement (THR), and to identify patients who are less likely to have consistent followup over 6 years postoperatively. METHODS We studied a population-based sample of 622 patients who received THR in 1995. We developed a multivariate ordinal regression model with the extent of radiographic followup as the dependent variable (none, early, and consistent), adjusting for demographic and preoperative clinical characteristics, and hospital and surgeon volume. RESULTS Ninety-four (15%) patients indicated that they had no followup radiographs, 269 (43%) had early followup only, and 259 (42%) had consistent followup radiographs over 6 years. Ninety percent of those with consistent followup orthopedic visits also had consistent followup radiographs over 6 years. Multivariate analyses revealed that older patients were less likely to have radiographic followup than younger patients (OR 0.76, 95% CI 0.65, 0.89) per each 5-year increase in age. Subjects with no college education were less likely to have radiographic followup than those with more education (OR 0.58, 95% CI 0.41, 0.83), and those with lower income were less likely to have radiographic followup than those with a higher income (OR 0.50, 95% CI 0.27, 0.92). CONCLUSION Only 42% of THR recipients reported consistent radiographic followup. Older patients, patients with lower income, and those with lower education level were less likely to have consistent radiographic followup over 6 years after THR. These population groups can serve as targets for interventions to improve followup after elective THR.

Abstract
OBJECTIVE Although early initiation of disease-modifying antirheumatic drugs (DMARDs) is effective in controlling short-term joint damage in individuals with rheumatoid arthritis (RA), the long-term benefit in disease progression is still controversial. We examined the long-term benefit of early DMARD initiation on radiographic progression in early RA. METHODS We identified published and unpublished clinical trials and observational studies from 1966 to September 2004 examining the association between delay to treatment initiation and progressive radiographic joint damage. We included studies of persons with RA disease duration <2 years and DMARD therapy of similar efficacy during followup. The differences in annual rates of radiographic progression between early and delayed therapy were pooled as standardized mean differences (SMDs). RESULTS A total of 12 studies met the inclusion criteria. The pooled estimate of effects from these studies demonstrated a significant reduction of radiographic progression in patients treated early (-0.19 SMD, 95% confidence interval [95% CI] -0.34, -0.04), which corresponded to a -33% reduction (95% CI -50, -16) in long-term progression rates compared with patients treated later. Patients with more aggressive disease seemed to benefit most from early DMARD initiation (P = 0.04). CONCLUSION These results support the existence of a critical period to initiate antirheumatic therapy, a therapeutic window of opportunity early in the course of RA associated with sustained benefit in radiographic progression for up to 5 years. Prompt initiation of antirheumatic therapy in persons with RA may alter the long-term course of the disease.

Abstract
OBJECTIVE To compare the diagnostic performance of a computer-based method for measuring joint space width with the Sharp joint space narrowing (JSN) scoring method in patients with rheumatoid arthritis (RA). METHODS A random sample of patients with early RA, for whom sequential hand radiographs and Sharp scores were available, was selected from the National Data Bank for Rheumatic Diseases. Hand joint space width was measured using an automated, computer-based method in random order and with blinding for clinical information. We constructed a receiver operating characteristic curve and compared the diagnostic performance of the computer-based and Sharp methods based on the areas under the curve. RESULTS One hundred twenty-nine patients with early RA who underwent serial radiography were included. Changes in the computer-based and Sharp methods were highly correlated (r = 0.75, P < 0.001). The computer-based method was significantly more discriminant than the Sharp JSN subscale. The area under the curve of the computer-based method was 0.96 (95% confidence interval [95% CI] 0.94, 0.99) compared with 0.93 (95% CI 0.89, 0.96) for the Sharp subscale (P = 0.024). At the most discriminant cutoff, specificity of the computer-based method was 88.4% compared with 81.4% for the Sharp subscale (P = 0.11); sensitivity was 87.6% for the computer-based method compared with 82.2% for Sharp subscale (P = 0.19). The signal-to-noise ratio for the computer-based method was 83% compared with 70% for the Sharp subscale (P = 0.013). CONCLUSION The computer-based method for measuring joint space width is more discriminant than the semiquantitative Sharp JSN subscale.

Abstract
OBJECTIVE The effectiveness of aggressive management of traditional risk factors for accelerated atherosclerosis in systemic lupus erythematosus (SLE) has been advocated but not proven. We conducted a pilot, randomized, controlled trial of known prevention medications (pravastatin, ramipril, aspirin, and a combination B vitamin) plus individualized cardiovascular prevention education. We describe our experience in recruiting and retaining patients with SLE in this trial. METHODS Patients with SLE by American College of Rheumatology criteria who lived within 1 hour of the hospital and had visits within the past 3 years were screened. All eligible patients were contacted by the principal investigator who was not their physician. The reasons for nonparticipation were elicited in a nonjudgmental manner. RESULTS A total of 662 patients met the selection criteria for the study. Of these, 295 patients (45%) with contraindications to study medications were excluded. Ninety-seven (40%) of 244 eligible patients refused to participate. More than 40% of those phoned were unwilling to participate and, among those, 19% felt they were too sick, too well, or taking too many medications already. A total of 41 patients were enrolled in the trial, and 22 dropped out within 4 months. CONCLUSION SLE is a chronic disease, and the development and testing of interventions aimed at the prevention of long-term sequelae are of paramount importance. Prevention trials in SLE face serious challenges, including the recruitment and retention of participants. Our experience provides insights into the barriers to participation in randomized prevention trials in SLE.

Abstract
OBJECTIVE To identify the factors associated with discharge to an inpatient rehabilitation facility versus discharge directly to home after elective total hip replacement (THR). METHODS Data were obtained from a medical record review and a cross-sectional survey of a population-based cohort of patients who received elective primary or revision THR in 1995. Postoperative functional status was measured as the ability to walk independently prior to discharge. A multivariate regression model was developed with discharge to an inpatient rehabilitation facility versus directly to home as the dependent variable. The model adjusted for demographic characteristics, socioeconomic features, and several preoperative and postoperative clinical factors. RESULTS We included 1,276 patients age 65-94 years in the analysis. Of these, 58% were discharged from the acute care hospital to a rehabilitation facility. The cohort had mean age of 73 years; 96% were white; 62% were female; 32% were living alone; 38% had an annual income less than $20,000; and 78% were unable to walk independently in the hospital before discharge. For primary THR patients, multivariate analysis showed a significant association between being discharged to a rehabilitation facility and being unable to walk at discharge, older age, obesity, and living alone. For revision THR patients, multivariate analysis also showed a significant association between being discharged to a rehabilitation facility and being unable to walk at discharge. CONCLUSION In a large population-based sample, postoperative functional status, age, obesity, and social support all influenced the discharge destination following elective THR.

Abstract
The main event in blood coagulation is the thrombincatalyzed conversion of fibrinogen into fibrin. This singular transformation of a soluble protein into an insoluble polymeric network occurs with faultless precision. Abnormalities of fibrin polymerization can lead to hemorragic and thrombotic disorders. Increased fibrinogen plasma concentration (Fg) and fibrin polymerization rate (FPR) could be additional risk factors associated with atherothrombosis in antiphospholipid syndrome (APS) and in systemic lupus erythematosus (SLE). Our objective was to investigate Fg and FPR in consecutive patients with APS and SLE. Thirty-nine patients and 31 age- and gender-matched healthy controls were studied. Sixteen patients had primary APS, 13 patients had SLE, and 10 patients had SLE plus APS. The mean of the FPR was significantly increased (0.2799 +/- 0.091) in patients with APS plus SLE as compared with the control group (0.2052 +/- 0.055) (p < 0.05). Fg was higher in APS plus SLE (3.15 g/L +/- 0.43) and in primary APS (3.03 g/L +/- 0.29) than in controls (2.87 g/L +/- 0.49). Our results demonstrated an increased FPR in patients with APS plus SLE. This phenomenon could be an additional risk factor for thrombosis in these autoimmune diseases.

Abstract
Carpal tunnel syndrome (CTS) is the most common peripheral nerve entrapment syndrome. CTS is a compression neuropathy caused by elevated pressure in the carpal tunnel. CTS has the potential to substantially limit performance of activities of daily living for some individuals. The goal of therapy for CTS is to improve symptoms and reduce signs of the disease, as well as prevent progression and loss of hand function. There are several treatment alternatives to relieve the pressure on the median nerve, both surgical and conservative. The most common measures employed in the initial treatment of CTS are NSAIDs, local and systemic corticosteroids, diuretics and pyridoxine. However, CTS treatment usually includes a combination of pharmacotherapy with other strategies such as splinting and activity modification. Injections of corticosteroids into the carpal tunnel are often employed for cases not responding to conservative treatment. Surgery is superior to conservative therapies for most persistently symptomatic patients. The aim of this paper is to review the pharmacological agents used for relieving the symptoms of CTS.
