Abstract
IMPORTANCE Although quality care markers exist for patients with rheumatoid arthritis (RA), the predictors of meeting these markers are unclear. OBJECTIVE To explore factors associated with quality care among patients with RA. DESIGN, SETTING, AND PARTICIPANTS A retrospective cohort study using insurance claims from 2009 to 2017 was conducted, and 6 sequential logistic regression models were built to evaluate quality care markers. Quality care markers were measured at 1 year post-RA diagnosis for each patient. The MarketScan Research Database, which contains commercial and Medicare Advantage administrative claims data from more than 100 million individuals in the US, was used to identify patients aged 18 to 64 years with a diagnosis claim for RA. Patients with conditions presenting similar to RA and missing demographic characteristics were excluded. Data analysis occurred between February 18 and May 5, 2022. EXPOSURES Success or failure to meet selected RA quality care markers within 1 year after RA diagnosis. MAIN OUTCOMES AND MEASURES Prevalence of meeting successive quality care markers for RA. RESULTS Among 581 770 patients, 430 843 (74.1%) were women and the mean (SD) age was 48.9 (11.3) years. Most patients (236 285 [40.6%]) resided in the South and had an income less than or equal to $45 200 (490 366 [84.3%]). Of the total study population, 399 862 individuals (68.7%) met at least 1 quality care marker and 181 908 (31.3%) met 0 markers. Most commonly, patients met annual laboratory testing (299 323 [51.5%]) and referral to a rheumatologist (256 765 [44.1%]) markers. The least met marker was receiving hepatitis B screening prior to initiation of disease-modifying antirheumatic drug (DMARD) therapy (18 548 [3.2%]). Women were most likely to meet all quality care markers except receiving DMARDs with hepatitis B screening (odds ratio, 1.14; 95% CI, 1.12-1.16). Individuals with lower median household income had lower odds of receiving a rheumatologist referral, an annual physical examination, or annual laboratory testing, but greater odds of receiving the other quality care markers. Patients with Medicare and those with comorbidities were generally less likely to meet quality care markers. CONCLUSIONS AND RELEVANCE In this cohort study of patients with RA, findings indicated downstream associations with rheumatologist referral and receiving DMARDs and varied associations between meeting quality care markers and patient characteristics. These findings suggest that prioritizing early care, especially for vulnerable patients, will ensure that quality care continues.

[PMID: 34830741 PMCID: PMC8618526 DOI: 10.3390/jcm10225460] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2021] [Revised: 11/04/2021] [Accepted: 11/11/2021] [Indexed: 11/20/2022] Open
Abstract
Objectives: To examine the comorbidity burden in patients with rheumatoid arthritis (RA) patients using a nationwide population-based cohort by assessing the Charlson Comorbidity Index (CCI), Elixhauser Comorbidity Index (ECI), Multimorbidity Index (MMI), and Rheumatic Disease Comorbidity Index (RDCI) scores and to investigate their predictive ability for all-cause mortality. Methods: We identified 24,767 RA patients diagnosed from 1998 to 2008 in Taiwan and followed up until 31 December 2013. The incidence of comorbidities was estimated in three periods (before, during, and after the diagnostic period). The incidence rate ratios were calculated by comparing during vs. before and after vs. before the diagnostic period. One- and 5-year mortality rates were calculated and discriminated by low and high-score groups and modified models for each index. Results: The mean score at diagnosis was 0.8 in CCI, 2.8 in ECI, 0.7 in MMI, and 1.3 in RDCI, and annual percentage changes are 11.0%, 11.3%, 9.7%, and 6.8%, respectively. The incidence of any increase in the comorbidity index was significantly higher in the periods of “during” and “after” the RA diagnosis (incidence rate ratios for different indexes: 1.33–2.77). The mortality rate significantly differed between the high and low-score groups measured by each index (adjusted hazard ratios: 2.5–4.3 for different indexes). CCI was slightly better in the prediction of 1- and 5-year mortality rates. Conclusions: Comorbidities are common before and after RA diagnosis, and the rate of accumulation accelerates after RA diagnosis. All four comorbidity indexes are useful to measure the temporal changes and to predict mortality.

Abstract
OBJECTIVE To examine the fracture risk with use of disease-modifying antirheumatic drugs (DMARDs), statins, proton pump inhibitors (PPIs), opioids, non-opioid analgesics and psychotropic medications in a US-wide observational rheumatoid arthritis (RA) cohort. METHODS Patients with RA without prior fracture from 2001 through 2017 in FORWARD, a longitudinal observational registry, were assessed for osteoporosis-related site fractures (vertebra, hip, forearm and humerus). DMARD exposure was assessed in four mutually exclusive groups: (1) methotrexate monotherapy-reference, (2) tumour necrosis factor-α inhibitors (TNFi), (3) non-TNFi biologics and (4) others. Non-DMARDs and glucocorticoids were classified as current/ever use and based on treatment duration. Fracture Risk Assessment Tool (FRAX) scores estimating for 10-year major osteoporotic fractures were calculated. Cox proportional hazard models stratified by FRAX were used to adjust for confounders. RESULTS During median (IQR) 3.0 (1.5-6.0) years of follow-up in 11 412 patients, 914 fractures were observed. The adjusted models showed a significant fracture risk increase with use of any dose glucocorticoids ≥3 months (HR (95% CI) for <7.5 mg/day 1.26 (1.07 to 1.48) and for ≥7.5 mg/day 1.57 (1.27 to 1.94)), opioids (for weak: 1.37 (1.18 to 1.59); strong: 1.53 (1.24 to 1.88)) and selective serotonin reuptake inhibitors (SSRIs) (1.37 (1.15 to 1.63)). Fracture risk with opioids increased within 1 month of use (1.66 (1.36 to 2.04)) and with SSRIs >3 months of use (1.25 (1.01 to 1.55)). Statins (0.77 (0.62 to 0.96)) and TNFi (0.72 (0.54 to 0.97)) were associated with reduction in vertebral fracture risk only. PPIs and other psychotropic medications were not associated with increased fracture risk. CONCLUSION Use of opioids, SSRIs and glucocorticoids were associated with increased risk of any fracture in patients with RA, whereas statins and TNFi were associated with decreased vertebral fractures.

Abstract
Objective.To evaluate compliance with diabetes screening guidelines for cardiovascular disease (CVD) prevention in rheumatoid arthritis (RA) compared to the general population.Methods.We conducted the first longitudinal study of a population-based RA cohort including all prevalent RA cases in British Columbia between 1996 and 2006 and followed until 2010, with matched general population comparators. Using administrative data, we measured compliance with general population guidelines [i.e., testing plasma glucose (PG) at least once every 3 years after age 45] after excluding individuals with previous diabetes. Followup was divided into 3-year eligibility periods. Compliance was measured as the proportion of periods with ≥ 1 PG test performed. OR (95% CI) of compliance in RA (vs general population) was calculated using generalized estimating equation models, adjusting for age and sex. Mean compliance rate per patient was also calculated and compared using the Mann-Whitney U test.Results.Analysis included 22,624 individuals with RA, contributing 48,724 three-year eligibility periods; and 22,579 people in a general population group, contributing 51,081 three-year eligibility periods. PG was measured in 72.3% (SD 37%) of the eligible time periods in the RA sample and in 70.4% (SD 38%) for the general population (OR 1.05, 95% CI 1.02–1.09, p < 0.0001). RA individuals met recommended screening guidelines in 71.4% of their eligible periods, compared to 70.6% (p < 0.001). Screening improved over time in RA relative to the general population. Family physicians ordered nearly all the PG tests.Conclusion.Compliance with general population guidelines for diabetes screening in RA was suboptimal, with little difference relative to the general population, despite a higher risk of CVD and diabetes.

Abstract
Autoimmune diseases such as rheumatoid arthritis (RA) and Sjögren syndrome (SS) ameliorate during pregnancy, through dampening (immunotolerance) of the maternal immune system which protects the fetus from rejection. A large number of studies have shown that human chorionic gonadotropin (hCG) contributes to this tolerance. Studies on animal models have reaffirmed that hCG treatment mimics the benefits of pregnancy. Based on the scientific evidence, randomized clinical trials comparing hCG with current therapies and/or placebo are recommended for RA, SS, and for other autoimmune diseases such as, type 1 diabetes and ankylosing spondylitis, which also get better during pregnancy and hCG treatment seems to help.

Abstract
The objective of the study was to develop evidence-based and practical recommendations for the detection and management of comorbidity in patients with rheumatoid arthritis (RA) in daily practice. We used a modified RAND/UCLA methodology and systematic review (SR). The process map and specific recommendations, based on the SR, were established in discussion groups. A two round Delphi survey permitted (1) to prioritize the recommendations, (2) to refine them, and (3) to evaluate their agreement by a large group of users. The recommendations cover: (1) which comorbidities should be investigated in clinical practice at the first and following visits (including treatments, risk factors and patient's features that might interfere with RA management); (2) how and when should comorbidities and risk factors be investigated; (3) how to manage specific comorbidities, related or non-related to RA, including major adverse events of RA treatment, and to promote health (general and musculoskeletal health); and (4) specific recommendations to assure an integral care approach for RA patients with any comorbidity, such as health care models for chronic inflammatory patients, early arthritis units, relationships with primary care, specialized nursing care, and self-management. These recommendations are intended to guide rheumatologists, patients, and other stakeholders, on the early diagnosis and management of comorbidity in RA, in order to improve disease outcomes.

Abstract
OBJECTIVE To describe long-term physical functioning and its association with somatic comorbidity and comorbid depression in patients with established rheumatoid arthritis (RA). METHODS Longitudinal data over a period of 11 years were collected from 882 patients with RA at study inclusion. Patient-reported outcomes were collected in 1997, 1998, 1999, 2002, and 2008. Physical functioning was measured with the Health Assessment Questionnaire and the physical component summary score of the Short Form 36 health survey. Somatic comorbidity was measured by a questionnaire including 12 chronic diseases. Comorbid depression was measured with the Center for Epidemiologic Studies Depression Scale. We distinguished 4 groups of patients based on comorbidity at baseline. RESULTS Seventy-two percent of the patients at baseline were women. The mean ± SD age was 59.3 ± 14.8 years and the median disease duration was 5.0 years (interquartile range 2.0-14.0 years). For the total group of patients with RA, physical functioning improved over time. Patients with somatic comorbidity, comorbid depression, or both demonstrated worse physical functioning than patients without comorbidity at all data collection points. Both groups with comorbid depression had the lowest scores. Only patients with both somatic comorbidity and comorbid depression showed significantly less improvement in physical functioning over time. CONCLUSION Both somatic comorbidity and comorbid depression were negatively associated with physical functioning during an 11-year followup period. Furthermore, their combination seems to be especially detrimental to physical functioning over time. These results emphasize the need to take somatic comorbidity and comorbid depression into account in the screening and treatment of patients with RA.

Abstract
Pro-inflammatory mediators produced during inflammatory response have been demonstrated to initiate and aggravate pathological development of several chronic diseases. Plant bioactive constituents have been reported to exert anti-inflammatory activities. Various parts of Moringa oleifera have long been used as habitual diets and traditional remedy along the tropical region. Anti-inflammatory activity of boiled M. oleifera pod extract was assessed by measuring pro-inflammatory mediator expression in the lipopolysaccharide-induced murine RAW264.7 macrophage cells. Prior treatment with 31-250 μg/mL M. oleifera extract for 1 h inhibited elevation of mRNA and protein level of interleukine-6, tumor necrosis factor-alpha, inducible nitric oxide synthase, and cyclooxygenease-2, induced by lipopolysaccharide for 24 h in a dose-dependent manner. The suppressive effect was mediated partly by inhibiting phosphorylation of inhibitor kappa B protein and mitogen-activated protein kinases. These results indicate that the anti-inflammatory activity from bioactive compounds present in the M. oleifera pod constituents may contribute to ameliorate the pathogenesis of inflammatory-associated chronic diseases.

Abstract
The objective of the present review is to highlight the relationship between low vitamin B6 status and CVD through its link with inflammation. While overt vitamin B6 deficiency is uncommon in clinical practice, increasing evidence suggests that marginal vitamin B6 deficiency is rather frequent in a consistent proportion of the population and is related to an increased risk of inflammation-related diseases. Ample evidence substantiates the theory of atherosclerosis as an inflammatory disease, and low plasma vitamin B6 concentrations have been related to increased CVD risk. Several studies have also shown that low vitamin B6 status is associated with rheumatoid arthritis and chronic inflammatory bowel diseases, both of which hold an underlying chronic inflammatory condition. Furthermore, the inverse association observed between inflammation markers and vitamin B6 supports the notion that inflammation may represent the common link between low vitamin B6 status and CVD risk. In addition to the epidemiological evidence, there are a number of cell culture and animal studies that have suggested several possible mechanisms relating impaired vitamin B6 status with chronic inflammation. A mild vitamin B6 deficiency characterises, in most cases, a subclinical at-risk condition in inflammatory-linked diseases which should be addressed by an appropriate individually tailored nutritional preventive or therapeutic strategy.

Abstract
Background Cumulative genetic profiles can help identify individuals at high-risk for developing RA. We examined the impact of 39 validated genetic risk alleles on the risk of RA phenotypes characterized by serologic and erosive status. Methods/Principal Findings We evaluated single nucleotide polymorphisms at 31 validated RA risk loci and 8 Human Leukocyte Antigen alleles among 542 Caucasian RA cases and 551 Caucasian controls from Nurses' Health Study and Nurses' Health Study II. We created a weighted genetic risk score (GRS) and evaluated it as 7 ordinal groups using logistic regression (adjusting for age and smoking) to assess the relationship between GRS group and odds of developing seronegative (RF− and CCP−), seropositive (RF+ or CCP+), erosive, and seropositive, erosive RA phenotypes. In separate case only analyses, we assessed the relationships between GRS and age of symptom onset. In 542 RA cases, 317 (58%) were seropositive, 163 (30%) had erosions and 105 (19%) were seropositive with erosions. Comparing the highest GRS risk group to the median group, we found an OR of 1.2 (95% CI = 0.8–2.1) for seronegative RA, 3.0 (95% CI = 1.9–4.7) for seropositive RA, 3.2 (95% CI = 1.8–5.6) for erosive RA, and 7.6 (95% CI = 3.6–16.3) for seropositive, erosive RA. No significant relationship was seen between GRS and age of onset. Conclusions/Significance Results suggest that seronegative and seropositive/erosive RA have different genetic architecture and support the importance of considering RA phenotypes in RA genetic studies.

Abstract
Introduction Although osteoporosis has been reported to be more common in patients with rheumatoid arthritis (RA), little is known whether the risk of osteoporotic fractures in these patients differs by age, sex, and anatomic site. Methods A retrospective cohort study was conducted using a health care utilization database. Incidence rates (IRs) and rate ratios (RRs) of osteoporotic fractures with 95% confidence intervals (CIs) were calculated. Multivariable Cox proportional hazards models compared the risk of osteoporotic fracture at typical sites between RA and non-RA patients. Results During a median 1.63-year follow-up, 872 (1.9%) of 47,034 RA patients experienced a fracture. The IR for osteoporotic fracture at typical sites among RA patients was 9.6 per 1,000 person-years, 1.5 times higher than the rate of non-RA patients. The IR was highest for hip fracture (3.4 per 1,000 person-years) in RA. The IRs across all age groups were higher for women than men and increased with older age in both groups. The RRs were elevated in RA patients across all common sites of osteoporotic fracture: hip (1.62, 95% CI 1.43 to 1.84), wrist (1.15, 95% CI 1.00 to 1.32), pelvis (2.02, 95% CI 1.77 to 2.30), and humerus (1.51, 95% CI 1.27 to 1.84). After confounding adjustment, a modest increase in risk for fracture was noted with RA (hazard ratio 1.26, 95% CI 1.15 to 1.38). Conclusions Our study showed an increased risk of osteoporotic fractures for RA patients across all age groups, sex and various anatomic sites, compared with non-RA patients.

Abstract
OBJECTIVES To describe and compare the prevalence of lifetime and current self-reported comorbidity and associated quality of life in 4 rheumatic diseases, and to investigate comorbid conditions in light of the overlap between the index condition and comorbid conditions (CC), and in the context of symptom-type diagnoses. METHODS We studied comorbidity in 11,704 patients with fibromyalgia (FM), systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), and noninflammatory rheumatic disorders (NIRD). Patients completed semiannual self-reports relating to 22 present and past illnesses and completed the EuroQol (EQ-5D) utility index. RESULTS CC were most common in FM, followed by SLE. FM comorbidity was dominated by depression, mental illness, and symptom-type comorbidity (e.g., gastrointestinal and genitourinary disorders). In SLE, there were substantial increases in hypertension, depression, cataract, fractures, and cardiovascular and cerebrovascular, neurologic, lung, gall bladder and endocrine disorders compared with RA. Any current CC reduced the EQ-5D utility by 0.08 to 0.16 units. The lowest EQ-5D score was noted for current psychiatric illness (0.55) and current depression (0.60). CONCLUSION Four patterns of comorbidity emerged: that associated with aging; that associated with aging but enhanced by the index condition, as in SLE and cardiovascular disease; comorbidity that is part of the symptoms complex of the index condition; and CC that represent lifetime traits or manifestations of the underlying illness. Depression was the most strongly associated correlate of EQ-5D quality of life, and current depression was present in about 15% of patients with RA or NIRD and 34% to 39% of those with SLE and FM.

Abstract
OBJECTIVE To evaluate the prognostic value of rheumatoid factor (RF), detected in the Waaler-Rose agglutination assay and by nephelometry, in patients with recent-onset rheumatoid arthritis (RA). METHODS Consecutive patients with new-onset RA between 1993 and 1997 were followed for a median period of 4.7 years. Clinical data at baseline and drug use during the disease course were recorded. Outcome parameters studied were disease process, damage (erosions, joint surgery, extra-articular manifestations, and new co-morbidity), and death. Cut-off levels for RF were >40 IU/mL (nephelometry) and titres 1:160 (Waaler-Rose haemagglutination). RESULTS RF tests were negative by both methods in 22% of RA patients (RF- group), while 33% were RF positive by nephelometry only (RF+ group) and 45% were positive by Waaler-Rose and nephelometry (RF++ group). Baseline clinical and laboratory findings as well as the number of subsequently used disease-modifying anti-rheumatic drugs (DMARDs), the number of patients starting and the time spent on steroid therapy were similar in the three RF groups. Odd ratios for death (n = 23), erosions (n = 62), and serious extra-articular disease manifestations (EAMs) (n = 13) as well as patient survival, erosion-free or surgery-free survival rates did not differ between the RF groups. Only rheumatoid nodules were more frequent in RF++ patients. CONCLUSION The baseline presence of RF by either Waaler-Rose or nephelometry was not associated with differences in drug therapy, morbidity other than rheumatoid nodules, or mortality in RA patients in the first 5 years of disease. Being immunoglobulin M (IgM) RF positive thus had little impact on RA patient outcome.

Abstract
The introduction of biologic response modifiers has revolutionized treatment approaches in rheumatoid arthritis. The ideal treatment approach to induce remission and minimize joint destruction is yet to be determined, however. The guidelines for the treatment of rheumatoid arthritis were updated in 2008. Evidence published recently may help to guide treatment decisions. In this review, advances in treatment approaches are discussed with added emphasis on the cardiovascular risks to this patient population. New data regarding the biologic response modifiers currently available in the US, abatacept and rituximab, are reviewed. Finally, emerging therapies are introduced, including tocilizumab. Investigational agents in development may provide additional options in the future treatment of rheumatoid arthritis.

Abstract
OBJECTIVE RANKL is essential for osteoclast development, activation, and survival. Denosumab is a fully human monoclonal IgG2 antibody that binds RANKL, inhibiting its activity. The aim of this multicenter, randomized, double-blind, placebo-controlled, phase II study was to evaluate the effects of denosumab on structural damage in patients with rheumatoid arthritis (RA) receiving methotrexate treatment. METHODS RA patients received subcutaneous placebo (n = 75), denosumab 60 mg (n = 71), or denosumab 180 mg (n = 72) injections every 6 months for 12 months. The primary end point was the change from baseline in the magnetic resonance imaging (MRI) erosion score at 6 months. RESULTS At 6 months, the increase in the MRI erosion score from baseline was lower in the 60-mg denosumab group (mean change 0.13; P = 0.118) and significantly lower in the 180-mg denosumab group (mean change 0.06; P = 0.007) than in the placebo group (mean change 1.75). A significant difference in the modified Sharp erosion score was observed as early as 6 months in the 180-mg denosumab group (P = 0.019) as compared with placebo, and at 12 months, both the 60-mg (P = 0.012) and the 180-mg (P = 0.007) denosumab groups were significantly different from the placebo group. Denosumab caused sustained suppression of markers of bone turnover. There was no evidence of an effect of denosumab on joint space narrowing or on measures of RA disease activity. Rates of adverse events were comparable between the denosumab and placebo groups. CONCLUSION Addition of twice-yearly injections of denosumab to ongoing methotrexate treatment inhibited structural damage in patients with RA for up to 12 months, with no increase in the rates of adverse events as compared with placebo.

Abstract
OBJECTIVE The purpose of this study was to determine if nonsupplementing older women (aged >or=55 years) with rheumatoid arthritis had higher plasma homocysteine and lower B-vitamin status compared to healthy controls. Elevated plasma homocysteine, a risk factor for cardiovascular disease, may help explain why individuals with rheumatoid arthritis have an increased risk of cardiovascular disease. METHODS Older, free-living women were classified as rheumatoid arthritis (n=18) or healthy control (n=33). Participants were not using B-vitamin supplements. Fasting blood samples were measured for pyridoxal 5'phosphate (PLP) (the metabolically active coenzyme form of vitamin B-6), folate, red blood cell folate, vitamin B-12, transcobalamin II, homocysteine, C-reactive protein, and lipid concentrations. Participants completed 7-day weighed food records, the Stanford Health Assessment Questionnaire (HAQ), and a visual analog pain scale. RESULTS PLP concentrations were lower in the rheumatoid arthritis vs healthy control participants (4.93+/-3.85 vs 11.35+/-7.11 ng/mL [20+/-16 vs 46+/-29 nmol/L]; P<0.01) whereas plasma homocysteine was higher in the rheumatoid arthritis group (1.63+/-0.74 vs 1.15+/-0.38 mg/L [12.1+/-5.5 vs 8.5+/-2.8 micromol/L]; P=0.02). Red blood cell folate concentrations were lower in the rheumatoid arthritis vs healthy control participants [414+/-141 vs 525+/-172 ng/mL [938+/-320 vs 1,190+/-390 nmol/L]; P=0.02). No significant differences were found for plasma folate, vitamin B-12, and transcobalamin II. An inverse correlation was found between PLP concentrations and the HAQ disability index (r=-0.37; P<0.01). A positive correlation was found between homocysteine concentrations and the HAQ disability index (r=0.36; P=0.01). Total cholesterol and low-density lipoprotein cholesterol levels were lower in the rheumatoid arthritis group (cholesterol 191+/-43 vs 218+/-33 mg/dL [4.95+/-1.11 vs 5.65+/-0.85 mmol/L]; P=0.02; low-density lipoprotein cholesterol 110+/-36 vs 137+/-29 mg/dL [2.85+/-0.93 vs 3.55+/-0.75 mmol/L]; P<0.01). No significant differences were seen between groups for protein (g/day), fat (g/day), cholesterol (mg/day), folate (microg/day), vitamin B-12 (microg/day), and vitamin B-6 (mg/day) dietary intakes. CONCLUSIONS Poor vitamin B-6 status and elevated plasma homocysteine concentrations were seen in older women with rheumatoid arthritis compared to healthy controls and may contribute to their increased risk of cardiovascular disease.

Abstract
BACKGROUND People with rheumatoid arthritis (RA) often have comorbidities with associated disability and complex medication regimens. Little published evidence exists about why people with RA require so many medications, although it is logical to hypothesize that this may relate to older age, longer duration of RA, more active RA, worse functional disability and a greater number of comorbidities. OBJECTIVES We set out to quantify polypharmacy in RA and identify its predictors in an observational cohort. METHODS The case notes of 348 people receiving secondary care for RA were reviewed to record polypharmacy. The 28-joint Disease Activity Score (DAS28) was calculated and the Health Assessment Questionnaire (HAQ) and the Self-administered Comorbidity Questionnaire (SCQ) were completed. RESULTS The mean total number of medications was 5.39, with a maximum of 16; of these, a mean of 2.41 medications were directly for RA. A mediational relationship was identified: older age and longer RA duration were significant predictors of a greater total number of medications, but these relationships were explained by the greater number of comorbidities in older participants and those with longer RA duration. Polypharmacy was not related to RA activity or functional disability. CONCLUSIONS Polypharmacy is common among people with RA and associates with older age and longer RA duration through a greater number of comorbidities. Regular review of the full treatment plan of individuals with RA by pharmacists and other health professionals specializing in rheumatology, to weigh the benefits and risks of each medication and their interactions in light of RA activity and comorbidities, is advocated.

Abstract
It has been emphasized recently that there is a strong association between atrial fibrillation and inflammation. Rheumatoid arthritis (RA), characterized by ongoing inflammatory activity, can increase the risk of atrial arrhythmia. P-wave dispersion has been encountered as a risk factor for atrial fibrillation and the effect of inflammation on P-wave dispersion has not been studied thoroughly. The aim of this study was to examine the effect of ongoing inflammatory activity in RA on P-wave dispersion. The study comprised 82 patients diagnosed with RA and 41 healthy volunteers as controls. Systolic functions of all participants were evaluated by echocardiography. Maximum P-wave duration and dispersion were calculated and found to be significantly increased in the RA group compared with the healthy controls. These parameters were also significantly correlated with C-reactive protein levels. The findings of this study suggest that RA may be associated with increases in P-wave dispersion and maximum P-wave duration, and that this association may result from ongoing inflammation.

Abstract
BACKGROUND Increased risks of morbidity and mortality from cardiovascular (CV) events are reported in patients with rheumatoid arthritis (RA). Recent reviews recommend aggressive treatment of modifiable CV risk factors, including systemic hypertension (HTN). OBJECTIVES We examined possible contributory factors influencing HTN treatment among RA patients by rheumatologists. METHODS We conducted a cross-sectional 36-item survey of randomly chosen rheumatologists from the American College of Rheumatology directory collecting the rheumatologists' demographics, practice, and perceptions regarding HTN treatment in their RA patients. Our response variable was initiation of HTN treatment. Independent variables were derived from responses to the survey, and data were analyzed using bivariate analysis and logistic regression. RESULTS Of 938 rheumatologists surveyed, 285 (30%) responded, 236 were subsequently analyzed. Respondents' mean age was 52.8 years; 75% were male and most were white (83%). Respondents reported routinely screening for HTN (92.8%), and initiating treatment for HTN (31%) in RA patients. Rheumatologists who believed that their RA patients did not have adequate visits with their primary care providers (PCP) were 2.2 times as likely to initiate treatment for HTN (41.1% vs. 24.3%; P = 0.006). Conversely, 33% of rheumatologists who did not routinely initiate treatment for HTN in their RA patients also did not believe patient access to PCP care was adequate. No associations were observed between initiation of HTN treatment and physician demographic or practice items. CONCLUSION The need for more effective minimization of CV risks in RA patients should prompt rheumatologists to consider a revision of routine practice standards to include treatment of uncontrolled HTN or promotion of improved communication with their PCPs.

Abstract
OBJECTIVES We undertook this study to test the hypotheses that patients with active rheumatoid arthritis (RA) are insulin resistant and that anti-tumour necrosis factor-alpha (TNFalpha) therapy improves not only the clinical state of these patients but also their glucose metabolism. METHODS Nine RA patients with active disease and nine healthy subjects, matched for sex, age, and body mass index (BMI), underwent a hyperinsulinaemic euglycaemic clamp. The RA patients received anti-TNFalpha therapy with Humira(adalimumab) and had the insulin clamp re-evaluated after 8 weeks of treatment. RESULTS Patients with RA had marked insulin resistance (glucose infusion rate (GIR) area under the curve (AUC) was 499+/-55 mg/kg in the RA group compared to 710+/-77 mg/kg in the control group; p<0.05). However, insulin sensitivity did not differ before and after 8 weeks of adalimumab therapy. The RA patients demonstrated a reduction in C-reactive protein (CRP) and interleukin-6 (IL-6) levels after the therapy as compared to pretreatment values, but there was no concomitant effect on plasma levels of TNFalpha. CONCLUSION RA patients with active disease showed marked insulin resistance that was not influenced by anti-TNFalpha therapy despite a reduction in systemic inflammation during the treatment.

Abstract
OBJECTIVE To identify risk factors for functional limitations in patients with ankylosing spondylitis (AS) of at least 20 years' duration. METHODS Patients with AS for > or =20 years were enrolled in the cross-sectional component of the Prospective Study of Outcomes in AS. All patients had clinical evaluations and completed questionnaires on functional limitations and potential risk factors. Functional limitations were assessed using the Bath Ankylosing Spondylitis Functional Index (BASFI; score range 0-100, higher scores indicate more limitations) and the Health Assessment Questionnaire for the Spondylarthropathies (HAQS). Risk factors included demographic characteristics, duration of AS, smoking status, number of comorbid medical conditions, recalled level of recreational activity in teens and twenties, occupational physical activity throughout life (rated 1 = little, 2 = moderate, 3 = heavy, and weighted by the number of years in each job), and history of AS in a first-degree relative. RESULTS The 326 patients (74% men) had a mean +/- SD age of 55.0 +/- 10.7 years, a mean duration of AS symptoms of 31.7 +/- 10.2 years, and a mean BASFI score of 40.7 +/- 25.6. BASFI scores increased with higher lifetime occupational physical activity (r = 0.31; P < 0.0001), the number of comorbid conditions (r = 0.25; P < 0.0001), and the duration of AS (r = 0.12; P = 0.04). BASFI scores were higher among current smokers compared with former/nonsmokers (55.5 versus 38.9; P = 0.0002), and among nonwhites compared with whites (49.9 versus 39.3; P = 0.02). In multivariable analyses, lifetime occupational physical activity, current smoking, education level, number of comorbid conditions, and family history were significantly associated with BASFI scores. The same risk factors were associated with the HAQS. CONCLUSION Functional limitations in patients with AS for >/=20 years are greater among those with a history of more physically demanding jobs, more comorbid conditions, and among smokers, and are less severe among those with higher levels of education and a family history of AS.

Abstract
OBJECTIVE The aim of this study was to evaluate left ventricular diastolic function in patients with active rheumatoid arthritis (RA), analyzing conventional Doppler and tissue Doppler echocardiographic imaging (TDI) which is a new echocardiographic application, with special regard to disease duration. METHODS Fifty-two patients with active RA and 47 healthy persons were included in this study. Duration of disease ranged from 3 to 324 months (mean 76+/-85 months). All patients and the control group were evaluated by M-mod, two-dimensional, conventional Doppler echocardiography and TDI. RESULTS Among conventional Doppler transvalvular mitral flow parameters, late diastolic flow velocity (A) and deceleration time (DT) values were higher in patients with RA than that in the control group (p<0.001). E (early diastolic flow velocity)/A ratio was found to be lower in patients with RA than that in the control group (p<0.001). Mitral annular early diastolic velocity (E (m)), among TDI parameters, was found to be lower in patients with RA than that in the control group (p<0.001). E (m)/A (m) (mitral annular late diastolic velocity) ratio was found to be lower in RA patients compared with that in the control group (p<0.001). The relation was found between A (r=0.43, p=0.001), DT (r=0.30, p=0.03), E/A ratio (r=0.40, p=0.004), E (m) (r=0.32, p=0.02), E (m)/A (m) ratio (r=0.30, p=0.03), and E/E (m) (r=0.32, p=0.02), with disease duration in patients with RA. CONCLUSION At present, it is concluded that active RA patients, in the absence of clinical evidence of heart disease, show diastolic dysfunction characterized by impaired E/A ratio, E (m)/A (m) ratio, and DT. The relation between diastolic dysfunction and disease duration suggests a subclinical myocardial involvement.

Abstract
Osteoarthritis (OA) of the knee and hip is a debilitating disease affecting more women than men and the risk of developing OA increases precipitously with aging. Rheumatoid arthritis (RA), the most common form of inflammatory joint diseases, is a disease of unknown etiology and affects approximately 1% of the population worldwide, and unlike OA, generally involves many joints because of the systemic nature of the disease. Non-steroidal anti-inflammatory drugs (NSAIDs) are the first drugs of choice for the symptomatic treatment of both OA and RA. Because of the risks associated with the use of NSAIDs and other limitations, the use of alternative therapies, such as acupuncture and medicinal herbs, is on the rise and according to reports approximately 60-90% of dissatisfied arthritis patients are likely to seek the option of complementary and alternative medicine (CAM). This paper reviews the efficacy of some of the common herbs that have a history of human use and their anti-inflammatory or antiarthritic properties have been evaluated in animal models of inflammatory arthritis, in studies employing well defined and widely accepted in vitro models that use human chondrocytes/cartilage explants or in clinical trials. Available data suggests that the extracts of most of these herbs or compounds derived from them may provide a safe and effective adjunctive therapeutic approach for the treatment of OA and RA. This, in turn, argues for trials to establish efficacy and optimum dosage of these compounds for treating human inflammatory and degenerative joint diseases.

METHODS Fifty-two patients with active RA and 47 healthy persons were included in this study. All patients and the control group were evaluated by M-mod, two-dimensional, conventional Doppler echocardiography and TDI. RESULTS Left ventricular early diastolic (E)/late diastolic (A) flow velocity (E/A ratio) was found to be lower in patients with RA than in the control group (p<0.001). Mitral annular early diastolic (E(m))/late diastolic (A(m)) velocity(E(m)/A(m) ratio) was found to decrease in RA patients compared with the control group (p<0.001). E/E(m) ratio was higher in patients with RA than in the control group (p<0.001). CONCLUSION Left ventricular diastolic functions were impaired in patients with RA. We have concluded that TDI alone, or together with conventional Doppler echocardiography, is useful for the evaluation of diastolic functions in RA patients.

Abstract
Rheumatoid arthritis (RA) is a chronic, systemic inflammatory disease, which continues to cause significant morbidity in affected persons. In the past few years, a number of new exciting therapeutic options have become available. These reflect the application of knowledge obtained from advancements in understanding of disease pathogenesis and underlying molecular mechanisms. A number of these therapies are outlined in the following review, including the various biological modifiers, in particular, anti-tumour necrosis factor-alpha agents and interleukin-1 (IL-1) receptor antagonists, which have been developed in recognition of the role of pro-inflammatory cytokines in RA. Also notable, is the current interest centring on the development and trials with B cell depletion therapies, specifically rituximab, in patients with RA. This demonstrates acknowledgment for a more significant role for B cells in the aetiology of RA, in contrast to the long held view that RA was a predominantly T cell mediated disease. To evaluate this therapeutic option for RA, salient features from recent rituximab trials have been collated. Finally, a selection of other therapeutic alternatives, including anti-IL-6 receptor monoclonal antibody and tacrolimus, and newer anti-rheumatic therapies presently in development are summarized.

Abstract
OBJECTIVE To determine whether systemic inflammation confers any additional risk for cardiovascular death among patients with rheumatoid arthritis (RA), after adjusting for traditional cardiovascular risk factors and comorbidities. METHODS Using the population-based data resources of the Rochester Epidemiology Project, we assembled an incidence cohort of all Rochester, Minnesota residents ages >or=18 years who first fulfilled the American College of Rheumatology 1987 criteria for RA between January 1, 1955 and January 1, 1995. All subjects were followed up longitudinally through their complete (inpatient, outpatient) medical records, beginning at age 18 years and continuing until death, migration, or January 1, 2001. Detailed information on the occurrence of various cardiovascular risk factors (personal history of coronary heart disease [CHD], congestive heart failure, smoking, hypertension, dyslipidemia, body mass index [BMI], diabetes mellitus, menopausal status) as well as indicators of systemic inflammation and RA disease severity (rheumatoid factor [RF] seropositivity, erythrocyte sedimentation rate [ESR], joint swelling, radiographic changes, RA nodules, RA complications, RA treatments, disease duration) and comorbidities were collected on all subjects. Causes of death were ascertained from death certificates and medical records. Cox regression models were used to estimate the independent predictors of cardiovascular death. RESULTS This inception cohort comprised a total of 603 RA patients whose mean age was 58 years, of whom 73% were women. During a mean followup of 15 years, 354 patients died and cardiovascular disease was the primary cause of death in 176 patients. Personal history of CHD, smoking, hypertension, low BMI, and diabetes mellitus, as well as comorbidities, including peripheral vascular disease, cerebrovascular disease, chronic pulmonary disease, dementia, ulcers, malignancies, renal disease, liver disease, and history of alcoholism, were all significant risk factors for cardiovascular death (P < 0.01 for each). Multivariable Cox regression analyses, controlled for cardiovascular risk factors and comorbidities, revealed that the risk of cardiovascular death was significantly higher among RA patients with at least 3 ESR values of >or=60 mm/hour (hazard ratio [HR] 2.03, 95% confidence interval [95% CI] 1.45-2.83), RA vasculitis (HR 2.41, 95% CI 1.00-5.81), and RA lung disease (HR 2.32, 95% CI 1.11-4.84). CONCLUSION These results indicate that markers of systemic inflammation confer a statistically significant additional risk for cardiovascular death among patients with RA, even after controlling for traditional cardiovascular risk factors and comorbidities.

Abstract
OBJECTIVE To develop a set of indicators for assessing the severity of rheumatoid arthritis (RA) through medical records. METHODS A list of 47 potential indicators of RA was reviewed by an expert Delphi panel of 6 rheumatologists. The Delphi method is a formal approach for gathering expert opinion. The 47 potential indicators included items from the following 5 categories: radiologic and laboratory findings, clinical and functional status measures, extraarticular manifestations, prior surgical history, and medications. The panelists rated the potential indicators' relationship to RA disease severity. Each panelist rated each indicator on a scale of 0-6, in which 0 indicated no relationship at all with severe RA and 6 indicated a perfect relationship with severe RA. After a baseline set of ratings, a literature review was distributed to the panelists along with the panel's initial mean ratings and the ranges. The panelists then met to discuss the literature and rerate all indicators. RESULTS After repeat ratings and review of relevant literature, the panel rated 28 of 47 (60%) potential indicators as having a strong or very strong relationship to severe RA. These 28 indicators were drawn from all 5 categories of potential indicators. There was agreement among the panelists on ratings for 41 of 47 indicators. Agreement was defined as a range of scores among the panelists </=3. CONCLUSION A Delphi panel of rheumatologists agreed that data generally available in medical records may serve as potential indicators of severe RA.

Abstract
First descriptions about cardiovascular manifestations (mostly myocarditis and endocarditis) in inflammatory rheumatic diseases were dated at the end of the 19(th) century. Inflammatory rheumatic diseases show an increased cardiovascular manifestation and mortality, but the reasons for this are unknown. This overview presents the current knowledge about cardiovascular manifestations in different inflammatory rheumatic diseases for an efficient differential diagnostic and clarification in the daily practice.

Abstract
BACKGROUND The risk of coronary heart disease (CHD) is increased in rheumatoid arthritis (RA). The reasons for this remain unknown, but traditional risk factors for CHD identified in the general population may be important contributors. OBJECTIVE To assess comparatively the prevalence of traditional CHD risk factors and the absolute 10-year CHD risk in patients with RA or osteoarthritis (OA) without known cardiovascular co-morbidity. METHODS Consecutive Caucasian hospital outpatients with RA (n = 150) or OA (n = 100) aged 40-75 years were assessed for known cardiovascular co-morbidity, age, sex, smoking status, presence of diabetes mellitus (DM), height, weight, systolic blood pressure (BP), total cholesterol (TC) and HDL cholesterol. Absolute 10-year CHD risk for each individual was calculated using the Joint British Societies CHD risk calculator. RESULTS Prevalence and distribution of known cardiovascular co-morbid conditions were similar in RA (56/150, 37%) and OA (34/100, 34%). The resulting subgroups of patients without known co-morbidity (RA: n = 94; OA: n = 66) were not significantly different for age, sex, DM, smoking, systolic BP or TC: HDL cholesterol ratio. There was no significant difference in the absolute 10-year CHD risk between RA and OA (15.6+/-11.0 versus 14.8+/-9.3, p = 0.63). However, a significant proportion of patients without known cardiovascular disease in both the RA and OA subgroups had a 10-year CHD risk above the 15% or 30% risk levels, indicating the need for possible or definite intervention respectively. Over 80% of RA patients had at least 1 CHD risk factor that could be modified. CONCLUSION Absolute 10-year CHD risk was not different between RA and OA patients in this study. Substantial numbers of RA and OA patients have potentially modifiable CHD risk factors present. We suggest that CHD risk should be assessed and modifiable risk factors addressed in the routine rheumatology clinic setting.

Abstract
OBJECTIVE The aim of the present study was to evaluate cardiac involvement in patients with active rheumatoid arthritis (RA). METHODS Forty patients with active RA participated. All were submitted to standard Doppler echocardiography and myocardial performance index (MPI) grading. RESULTS There were left and right ventricular diastolic function abnormalities in RA patients. Left ventricular MPI was also significantly higher than in controls ( P<0.05). A relationship was found between left ventricular early diastolic (E)/atrial (A) flow velocities (E/A ratio), isovolumic relaxation time (IRT), and disease duration ( r=-0.47 and P=0.002, r=0.618 and P=0.000, respectively). CONCLUSION Diastolic function was impaired in both ventricles in patients with active RA. There was a direct relationship between some of the parameters of left ventricular diastolic function and disease duration as well. These findings suggest a subclinical myocardial involvement in RA patients.

Abstract
OBJECTIVE The strongest known genetic association in rheumatoid arthritis (RA) is with HLA-DRB1 alleles that share a similar amino acid sequence, termed the shared epitope (SE). Although many studies have examined the association of the SE with disease severity, the results have been inconsistent, which may reflect the relatively small sample sizes or ethnic differences. The aim of this study was to assess the association of HLA-DRB1 SE alleles and genotype with the development of bony erosions in RA by meta-analysis. METHODS We identified English-language articles published between January 1, 1987 and June 1, 1999 through Medline, EMBase, and manual searches of 6 relevant journals. Included were studies in which molecular typing of HLA-DRB1 alleles was performed and in which the presence or absence of bony erosions was reported. Data were extracted from the studies, and erosions were coded as present or absent. Authors were contacted for missing information and data on individual patients. RESULTS A total of 29 studies and 3,240 patients were available for analysis. The summary odds ratios (ORs), when all patients were evaluated as a single group, demonstrated a significant association of the presence of the SE (2 or 1 versus 0 SE alleles) with erosions (OR 2.0; 95% confidence interval [95% CI] 1.8-2.2), although significant heterogeneity was present (P = 0.002). Subgroup analyses demonstrated the important influence of ethnic background. For example, no association of the SE with erosions was demonstrated in Greeks (OR 0.8 [95% CI 0.2-1.5]). In contrast, there was a striking dose-dependent relationship in southern European Caucasians and Asians, with ORs as high as 6.2 and 5.4, respectively, in patients with 2 SE alleles. Although our ability to assess the relationship between SE genotype and erosions was limited, particular importance of the DRB1*0401 SE allele was suggested in an analysis restricted to northern European Caucasians. CONCLUSION The SE is associated with the development of erosive disease in many ethnic groups; however, striking exceptions exist. These variations may be due to allele differences between populations, such as the frequency of DRB1*0401 among different ethnic groups. Further study to better understand the genetic and environmental differences between these populations may provide insight into mechanisms that influence the clinical expression of RA.

Abstract
Patients with rheumatoid arthritis (RA) face considerable physical, social and emotional disabilities. In this chronic disease, for which a cure is not yet available, improving patients' health-related quality of life (HRQoL) is of the utmost concern, particularly as the use of long-term and potentially toxic therapy increases. Early HRQoL outcome measures in RA focused on physical functioning, but the social and emotional aspects of the disease are now increasingly important. Thus, several generic and RA-specific HRQoL instruments have been developed, but no one tool covers all areas of HRQoL that affect the patient with RA. For this reason, a combination of generic and disease-specific tools is currently recommended for RA clinical trials.

Abstract
Rheumatoid arthritis (RA) is an immunologically mediated disorder characterized by progressive joint destruction that leads to significant impairment of functioning and quality of life. Its signs and symptoms vary, depending on disease activity. The goals of therapy in patients with RA include a reduction of symptoms, inhibition of structural damage, and improvement in physical function. The paradigm for managing RA calls for adopting a three-pronged strategy that addresses the different aspects of the disease. Infliximab, a biologic response modifier, has been shown to be an effective and safe therapy in patients with RA. Infliximab, in combination with oral or subcutaneous methotrexate, is administered intravenously, most commonly in an office-based setting. As with any intravenously administered protein, infusion-related adverse events have been reported with infliximab; however, such events are infrequent, and slowing the rate of the infusion may reduce their likelihood of occurring. These adverse events can generally be managed easily. Nurses who administer infliximab should have a thorough understanding of the product to prevent or manage adverse events. In this way, they can help ensure the safe delivery of the agent and optimize patient outcomes.

Abstract
Chronic pain and psychiatric disorders frequently co-occur. However, estimates of the magnitude of these associations have been biased by the use of select clinical samples. The present study utilized the National Comorbidity Survey [Arch. Gen. Psychiatry 51 (1994) 8-19] Part II data set to investigate the associations between a chronic pain condition (i.e. arthritis) and common mood and anxiety disorders in a sample representative of the general US civilian population. Participants (N=5877) completed the Composite International Diagnostic Interview [World Health Organization (1990)], a structured interview for trained non-clinician interviewers based on the revised third edition of the Diagnostic and Statistical Manual of Mental Disorders [American Psychiatric Association (1987)], and provided self-reports of pain and disability associated with a variety of medical conditions. Significant positive associations were found between chronic pain and individual 12-month mood and anxiety disorders [odds ratios (OR) ranged from 1.92 to 4.27]. The strongest associations were observed with panic disorder (OR=4.27) and post-traumatic stress disorder (OR=3.69). The presence of one psychiatric disorder was not significantly associated with pain-related disability, but the presence of multiple psychiatric disorders was significantly associated with increased disability. The findings of the present study raise the possibility that improved efforts regarding the detection and treatment of anxiety disorders may be required in pain treatment settings.

Abstract
OBJECTIVE To review the pharmacology, pharmacokinetics, efficacy, safety, and pharmacoeconomic impact of infliximab in the treatment of Crohn's disease (CD) and rheumatoid arthritis (RA). DATA SOURCES MEDLINE and Pre-MEDLINE (1966-June 2002) and manufacturer prescribing literature were employed to find English-language articles on infliximab. Additional studies and abstracts were identified from the bibliographies of reviewed literature and conference proceedings. STUDY SELECTION/DATA EXTRACTION All articles identified from data sources were evaluated, and all information deemed relevant was included in this review. Information regarding basic pharmacology was collected from studies in animals. Pharmacokinetic data were collected from human trials. Safety data were extracted from clinical trials and postmarketing surveillance. Priority was given to randomized, double-blind, placebo-controlled studies for the assessment of efficacy. All available economic evaluations were included. DATA SYNTHESIS Infliximab is a new monoclonal antibody that appears to work by a unique mechanism: inhibiting the action of tumor necrosis factor-alpha (TNF-alpha). Infliximab is administered by intravenous infusion. In clinical trials in CD, infliximab significantly decreased the CD activity index compared with placebo in treatment-resistant disease and significantly reduced the number of draining fistulas in fistulizing disease. In RA, when infliximab was added to methotrexate (MTX), it resulted in a significant improvement in most disease outcome measures when compared with MTX plus placebo. Few major adverse effects were reported in the clinical trials; however, serious adverse events, including malignancy and demyelination, have been reported in postmarketing surveillance. Also, increased susceptibility to infections (including tuberculosis) has been reported. CONCLUSIONS Infliximab is an effective new agent for the treatment of CD and RA. Its apparent unique mechanism of action makes infliximab an important addition to therapy. Caution should be exercised when considering infliximab for individuals who have chronic or recurrent infections, mild congestive heart failure (New York Heart Association [NYHA] class I/II), nervous system disorders, or live or have lived in an area endemic for histoplasmosis. Infliximab is contraindicated for patients with a clinically important, active infection, moderate to severe congestive heart failure (NYHA class III/IV), or an allergy to mouse proteins or any of the ingredients in infliximab. Further long-term efficacy, safety, and economic data on infliximab are required. Also, for the treatment of RA, the burden of administering infliximab (as a 2-hour supervised infusion) has to be considered when choosing among anti-TNF-alpha medication (as the other 2 approved agents, etanercept and adalimumab, can be self-administered by subcutaneous injection).

Abstract
In the last decade, there have been substantial advances in the treatment of rheumatoid arthritis with the addition of several new disease-modifying agents to the therapeutic armamentarium. Biological agents targeting tumour necrosis factor (TNF) represent one such important addition. Infliximab, a chimeric anti-TNF monoclonal antibody, has shown remarkable promise in alleviating the signs and symptoms of rheumatoid arthritis in addition to retarding radiographic disease progression when used in combination with methotrexate. In its pivotal phase III trial, the addition of infliximab to patients with methotrexate-refractory disease was associated with substantial clinical benefit. Using American College of Rheumatology criteria for improvement, one-half of patients receiving infliximab (3 mg/kg every 8 weeks) plus methotrexate showed at least 20% improvement compared with only 20% of those receiving placebo plus methotrexate (p < 0.001) with over one-half of eventual responders obtaining criteria for improvement by the second week of observation. Although its use has been met with much deserved enthusiasm, recent reports have highlighted several potential serious adverse effects associated with infliximab (and other TNF antagonists), including infusion reactions, congestive heart failure, drug-induced lupus, and CNS demyelination. In addition, recent reports have cited the potential for reactivation of mycobacterial and fungal infection in patients receiving infliximab, mandating appropriate tuberculosis screening prior to drug initiation. Although the frequency of serious drug-related toxicity (requiring discontinuation of the agent) appears to be quite low, these reports underscore the need for caution and close surveillance with the administration of TNF inhibitors, particularly given that strategies aimed at preventing toxicity remain unproven. Despite its potential for toxicity, infliximab remains a valuable alternative for patients with rheumatoid arthritis.

Abstract
Agents that block the action of tumor necrosis factor-alpha and recombinant interleukin-1 have been shown to be effective biologic treatment modalities in patients with rheumatoid arthritis. Given the immunosuppressive effects of tumor necrosis factor-alpha and interleukin-1 blockers, infections have emerged as possible complications of using these agents, an observation foreshadowed in prelicensure animal studies. At this time, hundreds of thousands of patients have received these drugs, and a wide variety of infectious complications has been reported, among which reactivation tuberculosis is most notable. Case reports alone, however, do not necessarily reflect a causal association between a therapeutic product and an adverse event. The authors review the infectious complications of the use of these agents as reported in the medical literature from November 2001 through October 2002.

Abstract
OBJECTIVE To determine whether rheumatoid arthritis (RA) is associated with excess mortality among older women. METHODS RA associated mortality was examined in a prospective cohort study that was started in 1986, and included 31 336 women aged 55-69 years without a history of RA at baseline. Up to 1997, 158 cases of RA were identified and validated against medical records. The relative risk (RR) and 95% confidence interval (CI) were calculated as measures of association between RA onset and subsequent mortality (overall and cause-specific) using Cox proportional hazards regression. RESULTS Compared with non-cases, women developing RA during follow up had a significantly increased mortality risk (RR=1.52; 95% CI 1.05 to 2.20). Mortality was higher among rheumatoid factor (RF) positive cases (RR=1.90; 95% CI 1.24 to 2.92) than among RF negative cases (RR=1.00; 95% CI 0.45 to 1.99). There were trends towards increased proportions of RA related deaths from infection (RR=3.61; 95% CI 0.89-14.69) and circulatory disease (RR=1.46; 95% CI 0.76 to 2.81) but not malignancy (RR=0.97; 95% CI 0.46 to 2.04). CONCLUSIONS RA was associated with significantly increased mortality in a cohort of older women, and the association appeared to be restricted to those with RF positive disease.

Abstract
Immunocompromised patients with rheumatic diseases have an increased risk of infections. A major risk factor for infection seems to be the immunosuppressive therapy used. Newer therapies for RA may lead to increased rates of infection by opportunistic pathogens such as Mycobacteria tuberculosis. Because disease manifestation may mimic signs and symptoms of infection, prompt diagnosis may be difficult. Familiarity with the likely infections and their causes should aid in obtaining the appropriate culture specimens.

Abstract
Rheumatoid arthritis (RA) is associated with increased comorbidity and mortality resulting from cardiovascular disease. A review of past and recent studies suggests that inflammation and thrombosis may provide a link between both diseases. This association has significant clinical implications for therapy, because many of the drugs used in the symptomatic treatment of RA, such as nonsteroidal anti-inflammatory drugs and the new cyclooxygenase (COX)-2-specific inhibitors, affect mediators of both inflammation and thrombosis. Recent studies have elucidated the potential effects of COX-2-specific inhibitors on thrombogenic events and their potential impact on cardiovascular disease. Although a causal effect of these drugs to increase the risk of cardiovascular disease has not been established, further investigation is needed on the effects of COX-2-specific inhibitors on cardiovascular risk. Such data would be of particular importance in determining appropriate therapeutic approaches to the treatment of patients with RA who are also at risk for cardiovascular events.

Abstract
Patients with rheumatoid arthritis (RA) have a reduced life expectancy when compared with the general population. Cardiovascular death is considered the leading cause of mortality in patients with RA; it is responsible for approximately half the deaths observed in RA cohorts. The prevalence of cardiovascular comorbidity is difficult to assess accurately, because cardiovascular disease (CVD) has a tendency to remain silent in the rheumatoid patient. It is not clear why rheumatoid patients have higher rates of coronary disease. Traditional cardiovascular risk factors do not seem to be wholly responsible for the increased cardiovascular risk. Novel cardiovascular risk factors, including inflammatory markers, have been identified over the past few years. It may be that these new cardiovascular risk factors are responsible for accelerating coronary heart disease in patients with RA. This article reviews recent literature relating to the epidemiology of cardiovascular disease in the context of RA.
