Amino-terminal pro-brain natriuretic peptide as a prognostic marker in patients with rheumatoid arthritis

Rheumatoid arthritis (RA) is associated with increased cardiovascular (CV) morbidity and mortality, of which amino-terminal pro-brain natriuretic peptide (NT-proBNP) is a predictor. The objective of the study was to investigate associations between NT-proBNP and age, gender, markers of inflammation, disease activity, and kidney function in RA patients, without co-morbidities potentially influencing NT-proBNP concentration. The study group consisted of 90 patients with RA, without clinically relevant coronary heart disease, hypertension, diabetes, advanced chronic kidney disease. The comprehensive assessment of clinical and laboratory parameters of inflammation, disease activity, and kidney function was performed. Plasma samples were frozen for NT-proBNP analysis. Carotid intima media thickness (cIMT) was determined by high-resolution B-mode ultrasonography. The mean NT-proBNP concentrations were significantly higher in a group of RA patients with high disease activity (DAS28 > 5.1) and in a group of patients with subclinical atherosclerosis diagnosed by cIMT ≥ 0.6 mm. In all RA patients, NT-proBNP correlated positively with the age, C-reactive protein, erythrocyte sedimentation rate, cIMT, tricipital skin fold and negatively with hand-grip strength, hemoglobin, red blood cell count, albumin. In the group of women with RA, we found significant positive correlation between NT-proBNP and cystatin-C. Also, patients with NT-proBNP level ≥ 100 pg/ml had significantly higher cystatin-C than those with lower NT-proBNP. NT-proBNP level, in RA patients without co-morbidities potentially influencing this level, is correlated with age, disease activity markers of inflammation, and subclinical renal impairment. It means that risk of CV disorders is higher in older patients with more active RA.     

Prevalence of metabolic syndrome in patients with rheumatoid arthritis in Morocco: a cross-sectional study of 179 cases

Rheumatoid arthritis (RA) is associated with an increased risk for cardiovascular disease (CVD). The prevalence of metabolic syndrome (MetS)—a major contributor to CVD—in RA seems to be increased, suggesting that systemic inflammation and antirheumatic therapy may contribute to its presence. We aimed to determine the prevalence of MetS in RA, to identify the potential factors associated with its presence, and to evaluate the influence of antirheumatic drugs on the occurrence of MetS in a cohort of Moroccan patients with RA. The prevalence of MetS was assessed cross-sectionally in 179 patients with RA over a period of 17 months (July 2011–December 2012). Three definitions of MetS were used (National Cholesterol Education Program/Adult Treatment Panel III 2005, International Diabetes Federation 2005, and American Association of Clinical Endocrinologists 2003). All statistical analyses were done using the SPSS software version 18.0. Multivariate logistic regression model was constructed to identify independent predictors of MetS in patients with RA. The prevalence of MetS in RA varied from 24.6 to 30.7 % according to the definitions used. In a multivariate logistic regression model, the severity of RA and less methotrexate use were identified as significant independent predictors of the presence of MetS in RA patients. Our study suggests that MetS is common among Moroccan patients with severe RA. Methotrexate therapy was identified as an independent factor associated with a reduced risk of having MetS in these patients, suggesting a drug-specific mechanism and making methotrexate a first-line disease-modifying antirheumatic drug in RA patients who are at high risk of developing MetS.     

Angiotensin-converting enzyme deletion allele is beneficial for the longevity of Europeans

The human angiotensin converting enzyme (ACE) gene is one of the most investigated candidate genes for cardiovascular diseases (CVD), but the understanding of its role among the elderly is vague. Therefore, this study focuses at: (a) testing the association of ACE polymorphism with CVD risk factors among the elderly, and (b) detecting the possible unequal distribution of ACE genotypes between senescent and younger segments of the European populations. The association of ACE I/D polymorphism with CVD health status [hypertension (HT), obesity, dislypidemia] in 301 very old subjects (88.2 ± 5 years; F/M = 221/80) was tested by means of logistic regression analysis. The meta-analysis of D allele frequency in general vs. elderly (80+ years) groups was conducted using all publicly available data for European populations comprising both age cohorts. Multiple multinomial logistic regression revealed that within this elderly sample, age (younger olds, 80–90 years), female sex (OR = 3.13, 95% CI = 1.59–6.19), and elevated triglycerides (OR = 2.53, 95% CI = 1.29–4.95) were positively associated with HT, while ACE polymorphism was not. It was also established that the DD genotype was twice as high in 80+ cohort compared to general population of Croatia (p < 0.00001). This trend was confirmed by the meta-analysis that showed higher D allele frequencies in olds from nine of ten considered European populations (OR = 1.19, 95% CI = 1.08–1.31). The data in elderly cohort do not confirm previously reported role of ACE DD genotype to the development of HT. Moreover, meta-analysis indicated that ACE D allele has some selective advantage that contributes to longevity in majority of European populations.     

Assessment of cardiovascular risk in rheumatoid arthritis: impact of the new EULAR recommendations on the score cardiovascular risk index

To assess the impact of the application of the European League against Rheumatism (EULAR) task force recommendations in the cardiovascular (CV) risk of a series of Spanish patients diagnosed with rheumatoid arthritis (RA). Two hundred consecutive RA patients seen at the rheumatology outpatient clinics of Bellvitge Hospital, Barcelona, were studied. Information on clinical features of the disease, classic CV risk factors, and history of CV events was assessed. Both the systematic coronary risk evaluation (SCORE) CV risk index and the modified SCORE (mSCORE) according to the last EULAR recommendations were calculated. Based on the classic CV risk factors, the mean ± standard deviation SCORE was 2.1 ± 2.3% (median, 2; interquartile range [IQR], 1–3). Twenty-three (11%) patients were above the threshold of high CV risk for the Spanish population (≥5%). Following the EULAR recommendations, a change in the score was required in 119 (59%) patients. Therefore, the mean mSCORE was 2.7 ± 2.9% (median, 2; IQR, 1–3) and, due to this, 28 (14%) patients were above the threshold of high CV risk. Nine (5%) had at least one ischemic CV event. Patients with CV events were older and had more CV risk factors and higher SCORE and mSCORE than those without CV events. Although a large proportion of patients from this series fulfilled the criteria for the application of the EULAR recommendations, the final impact on the calculated CV risk was low and clinically significant in only a few patients. However, an association between the mSCORE and the presence of ischemic CV events was observed.     

Relationship Between Forced Vital Capacity and Framingham Cardiovascular Risk Score Beyond the Presence of Metabolic Syndrome: The Fourth Korea National Health and Nutrition Examination Survey

Impaired lung function is a risk factor for cardiovascular (CV) events. However, it has not been well established whether FVC reduction even within normal range is associated with cardiovascular disease (CVD) risk and whether reduced FVC is an independent relationship of CVD irrespective of metabolic syndrome. Thus, we aimed to explore the relationship between FVC and CV-event risk using the FRS beyond the presence of metabolic syndrome or abdominal obesity in a representative Korean population based on data from the nationwide Korea National Health and Nutrition Examination Survey (KNHANES IV).The study population included 9688 subjects ≥ 30 years of age with no previous diagnosis of CVD and obstructive lung disease. Using a logistic regression model and area under the curve (AUC) analysis, we evaluated the relationship between FVC quintiles and CV-event risk using the Framingham Risk Score (FRS; ≥ 10% or ≥ 20%). In addition, we examined the effect of FVC on CV-event risk based on the presence of metabolic syndrome (MetS) and abdominal obesity.After adjusting for covariates, comparison of subjects in the lowest FVC (% pred) quintile (Q1) with those in the highest quintile (Q5) yielded an odds ratio (OR) of 2.27 (95% CI, 1.91–2.71) for intermediate and high risk, and 2.89 (95% CI, 2.31–3.61) for high risk. The ORs for cardiovascular risk using FRS also increased irrespective of the presence of abdominal obesity and MetS without significant interaction. Furthermore, the addition of FVC status to MetS status and abdominal obesity status significantly increased the AUC of the model predicting CV-event risk (P < 0.001 and P < 0.001).Our study demonstrates that FVC is inversely associated with 10-year CV-event risk, irrespective of MetS and abdominal obesity in the general population without obstructive lung disease. Furthermore, the addition of FVC to MetS or abdominal obesity increased prediction of CVD event risks, implying a potential role of FVC to predict CV events.     

Sodium Intake and Mortality Follow-Up in the Third National Health and Nutrition Examination Survey (NHANES III)

Background  Sodium restriction is commonly recommended as a measure to lower blood pressure and thus reduce cardiovascular disease (CVD) and all-cause mortality. However, some studies have observed higher mortality associated with lower sodium intake. Objective  To test the hypothesis that lower sodium is associated with subsequent higher cardiovascular disease (CVD) and all cause mortality in the Third National Health and Nutrition Examination Survey (NHANES III). Design  Observational cohort study of mortality subsequent to a baseline survey. Participants  Representative sample (n = 8,699) of non-institutionalized US adults age ≥30, without history of CVD events, recruited between 1988–1994. Measurements and main results  Dietary sodium and calorie intakes estimated from a single baseline 24-h dietary recall. Vital status and cause of death were obtained from the National Death Index through the year 2000. Hazard ratio (HR) for CVD mortality of lowest to highest quartile of sodium, adjusted for calories and other CVD risk factors, in a Cox model, was 1.80 (95% CI 1.05, 3.08, p = 0.03). Non-significant trends of an inverse association of continuous sodium (per 1,000 mg) intake with CVD and all-cause mortality were observed with a 99% CI of 0.73, 1.06 (p = 0.07) and 0.86, 1.04 (p = 0.11), respectively, while trends for a direct association were not observed. Conclusion  Observed associations of lower sodium with higher mortality were modest and mostly not statistically significant. However, these findings also suggest that for the general US adult population, higher sodium is unlikely to be independently associated with higher CVD or all-cause mortality.     

Relation of metabolic syndrome components to left ventricular mass in Mexican Americans versus non-Hispanic whites

Metabolic syndrome (MetS) is associated with increased risk for cardiovascular disease (CVD). Mexican Americans (MA) exhibit increases in CVD risk factors compared with non-Hispanic whites (NHW), but few data exist comparing the relation of MetS to subclinical CVD, for example, left ventricular (LV) mass. Asymptomatic subjects (104 MA and 101 NHW, 52.2% female, aged 48 ± 12 years) were studied by echocardiography (echo) and by blood and urine tests. Metabolic syndrome was defined based on the American Heart Association/National Heart, Lung, and Blood Institute definition. Echo LV mass was compared with the presence or absence of MetS and with the number of MetS components. Multiple linear regression also examined the association of MetS with LV mass adjusted for non-MetS risk factors. Left ventricular mass was lower in MA (145.5 ± 43.9 g) compared with NHW (160.2 ± 49.9 g) (P < .05), although this difference was attenuated after adjusting for MetS and other risk factors. Left ventricular mass was higher in those with vs without MetS in both MA and NHW men and women (P < .05 to P < .01). There was a significant (P < .001) graded increase in echo LV mass with increasing number of MetS components both in MA (108.3 to 153.8 g) and NHW (144.3 to 215.1 g). In multiple regression analysis, male sex and MetS remained independently associated (P < .0001) with LV mass; however, body mass index explained much of this association, indicating the strong association of obesity with LV mass. Mean LV mass in both MA and NHW adults was higher in those with vs without MetS and with increasing number of MetS components, with body mass index the principal component of MetS associated with LV mass. The prognostic significance of LV mass in persons with MetS requires further study.     

CTLA4 exon1 A49G polymorphism in Slovak patients with rheumatoid arthritis and Hashimoto thyroiditis—results and the review of the literature

Autoimmune thyroid diseases frequently overlaps with rheumatoid arthritis (RA). Among genetic factors, the role of the HLA antigens and CTLA4 gene polymorphisms in the overlapping has been suggested. The aim of this study was to investigate the alleles and genotypes frequency of the CTLA4 exon1 A49G polymorphism in Slovak patients with RA, Hashimoto thyroiditis (HT), both (RA + HT) and in healthy controls. Fifty-seven unrelated adults with RA, 57 patients with HT, 34 patients with both (RA + HT), and 51 normal subjects were studied. All were ethnic Slovaks living in the same geographical area. The CTLA4 exon1 A49G polymorphism was genotyped by using small amplicon melting analysis after real-time PCR. The CTLA4 49GG genotype and G allele frequency in the group with RA was not significantly higher in comparison with controls (10.53% vs. 9.8%, p = 0.62, OR 1.39, 95% CI 0.35–5.74 and 39.47% vs. 34.31%, p = 0.43, OR 1.25, 95% CI 0.72–2.18). The frequency of GG genotype was slightly but not significantly higher in patients with HT as compared with control group (19.3% vs. 9.8%, p = 0.17, OR 2.27, 95% CI 0.67–8.45). However, the frequency of GG genotype and G allele in patients with both RA and HT was significantly higher than that in controls (29.41% vs. 9.8%, p = 0.02, OR 4.49, 95% CI 1.20–18.54 and 51.47% vs. 34.31%, p = 0.03, OR 2.02, 95% CI 1.08–3.81). The frequency of GG genotype of CTLA4 A49G gene polymorphism in Slovak patients with RA is not significantly higher in comparison to control group. However, carriers of GG genotype with RA may be susceptible to develop HT.     

Prevalence of metabolic syndrome in rheumatoid arthritis patients from Northeastern Brazil: Association with disease activity

Objectives: To determine the prevalence of metabolic syndrome (MetS) in patients with rheumatoid arthritis (RA) and controls from Northeastern Brazil and to verify its association with specific RA parameters and cardiovascular risk factors.

Methods: The prevalence of MetS was assessed cross-sectionally in 338 RA patients from a single center and 84 age and gender-matched controls from the local community. MetS was defined according to NCEP/ATPIII guidelines. Disease activity was assessed with CDAI, SDAI and DAS28 scores. Independent risk factors for MetS in RA patients were identified by multivariate logistic regression.

Results: The prevalence of MetS was higher in RA patients than in controls (51.3% vs. 21.8%; p?p?p?=?.016) as independent risk factors for MetS in patients with RA.

Conclusion: RA in patients from Northeastern Brazil was found to be associated with increased WC, high prevalence of MetS (one of the highest in the world) and disease activity. Patients with MetS displayed a higher frequency of cardiovascular risk factors, indicating the need for better control of disease activity and modifiable risk factors for cardiovascular disease (CVD).     

Very recent onset arthritis: the value of initial rheumatologist evaluation and anti-cyclic citrullinated peptide antibodies in the diagnosis of rheumatoid arthritis

The objective of this study is to identify baseline factors associated with rheumatoid arthritis (RA) diagnosis at the end of 1-year follow-up in a cohort of patients with very recent onset arthritis. Incident cases with self-reported arthritis (≤12 weeks) referred by primary care physicians were assessed by a designated rheumatologist who predicted in those with ≥1 swollen joint the diagnosis of RA at the end of follow-up. Patients were regularly seen and diagnosed through follow-up by staff rheumatologists who were blind to diagnostic prediction. Of 119 referrals, 78 (65.5%; age 35.5 ± 13.5 years; 69 females) were diagnosed at baseline as very recent onset arthritis (median duration 6 weeks (0–12 weeks)); of 75 patients completing 1-year follow-up, 51 (66.5%) were classified as RA; 12 (16%) had self-limited arthritis; and 13 (17.5%) other diagnoses. The characteristics of patients with RA as final diagnosis were polyarthritis, morning stiffness ≥1 h, high counts of swollen joints, and low frequency of systemic symptoms. Rheumatologist prediction of RA and anti-cyclic citrullinated peptide (anti-CCP) antibodies was strongly associated with RA as a final diagnosis in the logistic regression analysis. Sensitivity and specificity of the rheumatologist prediction were 94% and 74%, for anti-CCP antibodies, 56% and 96%; the combination of both variables had a specificity of 100% and a sensitivity of 53%, and a positive predictive value of 98%. The combination of RA as predicted diagnosis by a rheumatologist and anti-CCP antibodies is highly specific for RA diagnosis in patients with very early arthritis.     

Antibodies against oxidized low-density lipoprotein are associated with subclinical atherosclerosis in recent-onset rheumatoid arthritis

Rheumatoid arthritis (RA) patients have increased mortality largely as a result of cardiovascular diseases (CVD) that cannot be explained by traditional risk factors, suggesting that systemic inflammation may accelerate atherosclerosis. We investigated the presence of subclinical atherosclerosis in early RA (<12 months) and the possible association of RA-related risk factors. Forty patients with early RA and 40 controls matched for age, sex, and traditional risk factors for CVD were selected. Carotid US examination, assay of lipogram, C-reactive protein (CRP), and oxidized low-density lipoprotein antibodies (OxLDL-ab) were done. RA patients had significantly higher carotid intima-media thickness (cIMT) values and more plaque than the control (P < 0.001 and P = 0.0122, respectively). CRP and OxLDL-ab were significantly higher in RA patients than controls. Traditional risk factors and RA-related risk factors (disease duration, DAS-28, duration of treatment with steroids, erythrocyte sedimentation rate, and CRP) as well as OxLDL and cIMT were significantly higher in RA with plaques compared to those without plaques. Regression analysis identified the age of patients, CRP, and OxLDL-ab as an independent risk factor associated with the presence of atherosclerosis. Conclusion: there is increased prevalence of carotid plaques in patients with recent-onset RA compared to matched controls. The accelerated atherosclerosis is predicted by age, CRP, and oxLDL-ab. The association of plaques with elevated CRP and OxLDL-ab support the hypothesis that chronic systemic autoimmune inflammatory process is probably a driving force for premature atherosclerosis.     

Prevalence and associations of hypertension and its control in patients with rheumatoid arthritis

OBJECTIVES: Rheumatoid arthritis (RA) associates with excessive cardiovascular morbidity and mortality. Hypertension (HT) contributes significantly to the development of cardiovascular disease (CVD). Little is known about the factors that influence blood pressure (BP) in patients with RA. In this study, we assessed the prevalence of HT in a secondary care cohort of RA patients, and aimed to identify factors associated with its presence and inadequate control. METHODS: A total of 400 consecutive RA patients were studied. HT was defined as systolic BP >/=140 mmHg and/or diastolic BP >/=90 mmHg or current use of antihypertensive drugs. The association of HT with several demographic and RA-related factors, comorbidities and drugs was evaluated using logistic regression. RESULTS: HT was present in 282 (70.5%) patients. Of those, 171 (60.6%) received anti-hypertensive therapy, but 111 (39.4%) remained undiagnosed. Of those treated, only 37/171 (21.8%) were optimally controlled. Multivariable logistic regression revealed age (OR = 1.054, CI: 1.02 to 1.07, P = 0.001), body mass index [BMI (OR = 1.06, CI: 1.003-1.121, P = 0.038)] and prednisolone use (OR = 2.39, CI: 1.02-5.6, P = 0.045) to be independently associated with the presence of HT. BMI (OR = 1.11, CI: 1.02-1.21, P = 0.002) and the presence of CVD (OR = 4.01, CI: 1.27-12.69, P = 0.018) associated with uncontrolled HT. CONCLUSIONS: HT is highly prevalent in RA, under-diagnosed particularly in the young, and under-treated particularly in old RA patients with CVD. RA patients receiving steroids should be specifically targeted for screening and treatment; those with any cardiovascular comorbidity may require particularly aggressive monitoring and treatment strategies.     

Relationship of elevated casual blood glucose level with coronary heart disease, cardiovascular disease and all-cause mortality in a representative sample of the Japanese population. NIPPON DATA80

Aims/hypothesis High fasting blood glucose is one of the well-known risk factors for CHD. However, in certain settings, patients cannot always be expected to fast. For example, community screenings for cardiovascular disease (CVD) risk factors in Japan are performed under non-fasting conditions to achieve high participation rates. Thus, we examined a representative cohort of the Japanese population (n = 9,444, follow-up period 17.3 years) to clarify whether high casual blood glucose (CBG) can predict CVD mortality. Methods We defined CBG groups as follows: high CBG ≥ 11.1 mmol/l or participants with a history of diabetes mellitus; borderline high, 7.77 ≤ CBG < 11.1 mmol/l; higher normal, 5.22 ≤ CBG < 7.77 mmol/l); and lower normal, CBG < 5.22 mmol/l. The multivariate-adjusted hazard ratios (HRs) for CHD, CVD and all-cause mortality were calculated. Results The crude CHD mortality rate was 0.84 per 1,000 person-years. Age- and sex-adjusted HRs for CHD mortality were high among participants with CBG levels  ≥ 7.77 mmol/l, regardless of time since last meal. Multivariate-adjusted HRs (95% CI) of CHD mortality in high and borderline high CBG groups were 2.62 (1.46–4.67) and 2.43 (1.29–4.58), respectively. Similar results were observed for both CVD and all-cause mortality. Even within the normal blood glucose range, each 1 mmol/l increase in CBG was associated with a statistically significant increase in the HR for CVD mortality (1.12, 95% CI 1.02–1.22). Population-attributable fractions of the combined groups of high and borderline high CBG for CHD, CVD and all-cause mortality were 12.0, 4.9 and 3.5%, respectively. Conclusions/interpretation Increases in CBG, even within the normal range, predict CVD mortality.

Association of cardiovascular disease and traditional cardiovascular risk factors with the incidence of dementia among patients with rheumatoid arthritis

ObjectiveTo determine the incidence of dementia in patients with rheumatoid arthritis (RA) 65 years and older, and compare the incidence of dementia in patients with RA with prevalent cardiovascular (CV) disease (CVD), CV risk factors but no prevalent CVD and neither (referent group).MethodsWe analyzed claims data from the Center for Medicare & Medicaid Services (CMS) from 2006–2014. Eligibility criteria included continuous medical and pharmacy coverage for ≥ 12 months (baseline period 2006), > 2 RA diagnoses by a rheumatologist and at least 1 medication for RA. CVD and CV risk factors were identified using codes from the Chronic Condition Data Warehouse. Incident dementia was defined by 1 inpatient or 2 outpatient claims, or one dementia specific medication. Age-adjusted incident rates were calculated within each age strata. Univariate and multivariate Cox proportional hazard models were used to calculate Hazard Ratios (HR) and 95% confidence intervals.ResultsAmong 56,567 patients with RA, 11,789 (20.1%) incident cases of dementia were included in the main analysis. Age adjusted incident rates were high among all groups and increased with age. After adjustment for age, sex, comorbidities and baseline CV and RA medications, patients with CVD and CV risk factors between 65 and 74 years had an increased risk for incident dementia compared to those without CVD and without CV risk factors (HR 1.18 (95% CI 1.04–1.33) and HR 1.03 (95% CI 1.00–1.11), respectively). We observed a trend towards increased risk in patients between 75 and 84 years with CVD at baseline.ConclusionPatients with RA with both CVD and CV risk factors alone are at an increased risk for dementia compared to those with neither CVD nor CV risk factors; however, this risk is attenuated with increasing age. The impact of RA treatment and CV primary prevention strategies in the prevention of dementia in patients with RA warrants further studies.     

Influence of Caregiving on Lifestyle and Psychosocial Risk Factors Among Family Members of Patients Hospitalized with Cardiovascular Disease

Background  Few data have evaluated the relationship between caregiving and cardiovascular disease (CVD) risk. Objective  The purpose of this study was to determine the prevalence and predictors of caregiver strain and to evaluate the association between caregiving and CVD lifestyle and psychosocial risk factors among family members of recently hospitalized CVD patients. Design and Participants  Participants in the NHLBI Family Intervention Trial for Heart Health (FIT Heart) who completed a 6-month follow-up were included in this analysis (n = 263; mean age 50 ± 14 years, 67% female, 29% non-white). Measurements  At 6 months, standardized information was collected regarding depression, social support, and caregiver strain (high caregiver strain = ≥7). Information on lifestyle risk factors, including obesity, physical activity, and diet, were also collected using standardized questionnaires. Logistic regression models on the association between caregiving and CVD risk factors were adjusted for significant confounders. Results  The prevalence of serving as a CVD patient’s primary caregiver or caring for the patient most of the time was 50% at 6 months. Caregivers (primary/most) were more likely to be women (81% vs 19%, p < .01), married/living with someone (p < .01), >50 years old (p < .01), have ≤ high school education (p < .01), be unemployed (p < .01), get less physical activity (p < .01), and have a higher waist circumference (p < .01) than non-caregivers (some/occasional/none). Mean caregiver strain scores were significantly higher among those with depressive symptoms (p < .01) and low social support (p < .01) in a multivariable adjusted model. Conclusions  Caregivers of cardiac patients may be at increased risk themselves for CVD morbidity and mortality compared to non-caregivers due to suboptimal lifestyle and psychosocial risk factors.     

Coffee consumption and risk of cardiovascular events and all-cause mortality among women with type 2 diabetes

Aims/hypothesis  Coffee has been linked to both beneficial and harmful health effects, but data on its relationship with cardiovascular disease and mortality in patients with type 2 diabetes are sparse. Methods  This was a prospective cohort study including 7,170 women with diagnosed type 2 diabetes but free of cardiovascular disease or cancer at baseline. Coffee consumption was assessed in 1980 and then every 2–4 years using validated questionnaires. A total of 658 incident cardiovascular events (434 coronary heart disease and 224 stroke) and 734 deaths from all causes were documented between 1980 and 2004. Results  After adjustment for age, smoking and other cardiovascular risk factors, the relative risks were 0.76 (95% CI 0.50–1.14) for cardiovascular diseases (p trend = 0.09) and 0.80 (95% CI 0.55–1.14) for all-cause mortality (p trend = 0.05) for the consumption of ≥4 cups/day of caffeinated coffee compared with non-drinkers. Similarly, multivariable RRs were 0.96 (95% CI 0.66–1.38) for cardiovascular diseases (p trend = 0.84) and 0.76 (95% CI 0.54–1.07) for all-cause mortality (p trend = 0.08) for the consumption of ≥2 cups/day of decaffeinated coffee compared with non-drinkers. Higher decaffeinated coffee consumption was associated with lower concentrations of HbA_1c (6.2% for ≥2 cups/day versus 6.7% for <1 cup/month; p trend = 0.02). Conclusions  These data provide evidence that habitual coffee consumption is not associated with increased risk of cardiovascular diseases or premature mortality among diabetic women.

Serum adiponectin concentrations correlate with severity of rheumatoid arthritis evaluated by extent of joint destruction

Adiponectin is a hormone released by adipose tissue with antidiabetic, antiatherogenic, and anti-inflammatory properties. The present observational study focused on the relation between serum adiponectin level and the disease severity of established rheumatoid arthritis (RA). Ninety patients with more than 5-year diagnosis of RA and 42 age- and BMI-matched control were enrolled. The severity of RA was evaluated according to the number of destructed joints of overall 68 joints on plain radiographs (37 patients had mild RA and 53 had severe RA). Serum adiponectin level was significantly higher in the severe RA group (17.7 ± 6.7 μg/ml) than in the control (9.1 ± 3.8 μg/ml) and mild RA groups (13.9 ± 6.5 μg/ml) (control vs. mild RA group, P < 0.001; mild RA vs. severe RA group, P < 0.01). These results suggest that increased number of joint destruction is associated with hyperadiponectinemia in established RA patients.     

Impact of using a non-diabetes-specific risk calculator on eligibility for statin therapy in type 2 diabetes

Aims/hypothesis  The aim of this study was to investigate the impact of using a non-diabetes-specific cardiovascular disease (CVD) risk calculator to determine eligibility for statin therapy according to current UK National Institute for Health and Clinical Excellence (NICE) guidelines for those patients with type 2 diabetes who are at an increased risk of CVD (10 year risk ≥20%). Methods  The 10 year CVD risks were estimated using the UK Prospective Diabetes Study (UKPDS) Risk Engine and the Framingham equation for 4,025 patients enrolled in the Lipids in Diabetes Study who had established type 2 diabetes and LDL-cholesterol <4.1 mmol/l. Results  The mean (SD) age of the patients was 60.7 (8.6) years, blood pressure 141/83 (17/10) mmHg and the total cholesterol:HDL-cholesterol ratio was 3.9 (1.0). The median (interquartile range) diabetes duration was 6 (3–11) years and the HbA_1c level was 8.0% (7.2–9.0%). The cohort comprised 65% men, 91% whites, 4% Afro-Caribbeans, 5% Asian Indians and 15% current smokers. More patients were classified as being at high risk by the UKPDS Risk Engine (65%) than by the Framingham CVD equation (63%) (p < 0.0001). The Framingham CVD equation classified fewer men and people aged <50 years old as high risk (p < 0.0001). There was no difference between the UKPDS Risk Engine and Framingham classification of women at high risk (p = 0.834). Conclusions/interpretation  These results suggest that the use of Framingham-derived rather than UKPDS Risk Engine-derived CVD risk estimates would deny about one in 25 patients statin therapy when applying current NICE guidelines. Thus, under these guidelines the choice of CVD risk calculator is important when assessing CVD risk in patients with type 2 diabetes, particularly for the identification of the relatively small proportion of younger people who require statin therapy.     

Repeated tuberculin skin testing following therapy with TNF-alpha inhibitors

To determine the rate of true tuberculin skin test (TST) response in a cohort of patients with rheumatic disease treated with tumor necrosis factor inhibitors (TNFi). The study population included consecutive patients with rheumatoid arthritis (RA), ankylosing spondylitis (AS), and psoriatic arthritis (PsA) treated with TNFi for at least 3 months. Patients with a positive TST at screening who began Tb prophylaxis before the beginning of TNFi therapy were excluded. All patients underwent a second TST. True TST response was defined as an increase of 6 mm of induration between the screening test and the second test. Forty patients (12 men and 28 women) were included. Mean age was 51.2 years. Of them, 27 (67.5%) had RA, eight (20%) had PsA, and five patients (12.5%) had AS. At pre-treatment TST, 15 patients had a TST ≥ 5 mm. A significantly higher percent of patients with TST ≥ 5 mm was seen among men compared with women (75% vs. 21%, p = 0.012) and patients with PsA compared with patients with RA (75% vs. 22%, p = 0.014). At the second test, eight (20%) had an increase of 6 mm between readings with four having an increase of 10 mm or more. Four patients received infliximab and the other four were treated with etanercept. Seven of these eight patients had RA and one was a patient with PsA. Patients with true TST response were significantly older and non-smokers with elevated sedimentation rate and a higher rate of anemia. Nationality, comorbid conditions, treatment with immunosuppressives, and BCG vaccination status had no significant influence on the TST response. Serial TST testing in patients receiving TNFi is indicated to identify patients with reactivation of latent tuberculosis infection or those exposed to mycobacterium.     

Prevalence of overweight in Moroccan patients with rheumatoid arthritis and its relationships with disease features

We aimed to estimate the prevalence of overweight in Moroccan patients with rheumatoid arthritis (RA) and its relationships with disease activity, functional disability, structural damage, and immunological status. Two hundred fifty patients with RA were consecutively included. Patients’ characteristics were specified. The following data were collected: age, disease duration, disease activity (evaluated with physical examination data, biological tests (erythrocyte sedimentation rate and C-reactive protein), and the disease activity score (DAS28)), radiographic changes (assessed by the Sharp’s method), functional disability (assessed by using the Health Assessment Questionnaire), extra-articular manifestations, immunological status, and treatment details. Overweight was defined according to the body mass index (BMI) values: underweight, <18.5; normal weight, 18.5–24.9; overweight, 25–29.9; and obesity, ≥30. The mean age of patients was 46.31 ± 12.64 years. The mean disease duration was 9.46 ± 8.43 years. Seventy-five patients (30%) were overweight, 42 (16.8%) were obese, and 133 (53.2%) were normal. Increased BMI was associated with the activity of disease (DAS28) (r = 0.426), structural damage (Sharp total score) (r = 0.297), the rate of rheumatoid factor (r = 0.311), and with the rate of anti-cyclic citrullinated protein antibodies (for all p ≤ 0.01). There were no statistically significant differences in BMI according to gender, dose and duration of corticosteroids, or functional impairment. In our sample, overweight seems to be prevalent in our RA patients. Overweight seems to occur independently of treatment and shown to be mainly associated to disease activity, structural damage, and immunological status. Large studies are needed to confirm those results.
