RESUMO
Statins are among the most commonly prescribed medications worldwide. Statin-associated muscle symptoms (SAMS) represent a frequent statin-related adverse effect associated with statin discontinuation and increased cardiovascular disease (CVD) events. Emerging evidence indicate that the majority of SAMS might not be actually caused by statins, and the nocebo/drucebo effect (i.e. adverse effects caused by negative expectations) might also explain SAMS. Physical activity (PA) is a cornerstone in the management of CVD risk. However, evidence of increased creatine-kinase levels in statin-treated athletes exposed to a marathon has been generalized, at least to some extent, to the general population and other types of PA. This generalization is likely inappropriate and might induce fear around PA in statin users. In addition, the guidelines for lipid management focus on aerobic PA while the potential of reducing sedentary behavior and undertaking resistance training have been overlooked. The aim of this report is to provide a novel proposal for the concurrent prescription of statin therapy and PA addressing the most common and clinically relevant scenarios by simultaneously considering the different stages of statin therapy and the history of PA. These scenarios include i) statin therapy initiation in physically inactive patients, ii) PA/exercise initiation in statin-treated patients, iii) statin therapy initiation in physically active patients, and iv) statin therapy in athletes and very active individuals performing SAMS-risky activities.

OBJECTIVES: To assess the associations and prognostic value of scleroderma patterns by nailfold videocapillaroscopy (NVC) in patients with systemic sclerosis (SSc) and cutaneous subsets. METHODS: At baseline, 1356 SSc patients from the RESCLE registry were compared according to the scleroderma pattern as Late pattern and non-Late pattern, which included Early and Active patterns. Patient characteristics, disease features, survival time and causes of death were analysed. RESULTS: Late pattern was identified in 540 (39.8%), and non-Late pattern in 816 (60.2%) patients (88% women; 987 lcSSc/251 dcSSc). Late pattern was associated to dcSSc (OR=1.96; p<0.001), interstitial lung disease (ILD) (OR=1.29; p=0.031), and scleroderma renal crisis (OR=3.46; p<0.001). Once the cutaneous subset was disregarded in an alternative analysis, both digital ulcers (DU) (OR=1.29; p<0.037) and anti-topoisomerase I antibodies (OR=1.39; p< 0.036) emerged associated with the Late pattern. By cutaneous subsets, associations with Late pattern were: (1) in dcSSc, acro-osteolysis (OR=2.13; p=0.022), and systolic pulmonary artery pressure >40 mmHg by Doppler echocardiogram (OR=2.24; p<0.001); and (2) in lcSSc, ILD (OR=1.38; p=0.028). Survival was reduced in dcSSc with Late pattern compared to non-Late pattern (p=0.049). Risk factors for SSc mortality in multivariate regression Cox analysis were age at diagnosis (HR=1.03; p<0.001), dcSSc (HR=2.48; p<0.001), DU (HR=1.38; p=0.046), ILD (HR=2.81; p<0.001), and pulmonary arterial hypertension (HR=1.99; p<0.001). CONCLUSIONS: SSc patients with Late pattern more frequently present dcSSc and develop more fibrotic and vascular manifestations. Advanced microangiopathy by NVC identifies dcSSc patients at risk of reduced survival due to SSc-related causes.

INTRODUCTION: Endothelin antagonist receptors (ERAs) and phosphodiesterase-5 inhibitors (PDE5i) are beneficial in pulmonary arterial hypertension (PAH) and digital ulcers (DU) and prevent from DU recurrences. Our study aimed to determine the difference in the incidence rate of PAH and scleroderma renal crisis (SRC) in patients with SSc and DU (SSc-DU) under ERAs/PDE5i or without treatment. METHODS: We conducted a retrospective cohort study including SSc-DU patients from the Spanish Scleroderma Registry (RESCLE). The primary outcome was the incidence rate of PAH and SRC in patients under ERAs/PDE5i or not. RESULTS: Some 544 patients out of 1817 (29.9%) in the RESCLE database had DU, 221 (40.6%) under ERAs/PDE5i and 323 (59.4%) not. The incidence rate (95% CI) difference between patients under treatment or not under did not reach statistical significance in PAH [-0.1 (-4.8, 4.69), P = 0.988] or in SRC [0.7 (-2.2, 3.7), P = 0.620]. However, the time from the first DU to the diagnosis of SRC was delayed in treated patients [mean (s.d.) 7.6 (5.8) years vs 2.9 (5.3); P = 0.021]. The dcSSc subset was more prevalent in the treatment group (36 vs 26%; P = 0.018), along with anti-topoisomerase I antibodies (34 vs 18%; P < 0.001) and tendon friction rubs (12 vs 6%; P = 0.038), whereas the lcSSc subset was more prevalent in the no-treatment group (57 vs 66%; P = 0.031) along with ACA (37 vs 46%; P = 0.031). CONCLUSION: There was no difference in the incidence rate of PAH and SRC between groups. However, treatment with ERAs and/or PDE5i appeared to delay the occurrence of SRC.

OBJECTIVES: Diffuse cutaneous systemic sclerosis (dcSSc) is associated with anti-topoisomerase (ATA) whereas limited cutaneous (lcSSc) and sine scleroderma (ssSSc) are mainly associated with anti-centromere antibody (ACA). Serodiscordant patients were defined as lcSSc subjects with ATA, dcSSc with ACA, and ssSSc with ATA. The aim of the present study was to compare the clinical manifestations and prognosis between serodiscordant patients and their counterparts (those with lcSSc with ACA, dcSSc with ATA and ssSSc with ACA, respectively). METHODS: From the Spanish Scleroderma Registry we selected those patients for whom skin involvement (dcSSc, lcSSc or ssSSc) was detailed at baseline and last visit and ACA and ATA had been determined. Demographic, clinical characteristics, and survival data were compared according to the antibody status. RESULTS: The whole cohort comprised 901 patients and six mutually exclusive groups were defined: lcSScACA in 511 (57%) patients, lcSScATA group in 87 (10%), dcSScATA group in 172 (19%), dcSScACA group in 21 (2%), ssSScACA group in 92 (10%), and ssSScATA group in 18 (2%) patients, respectively. Interstitial lung disease (ILD) and severe ILD were more frequent in patients with dcSScATA than in those with dcSScACA. Conversely, the prevalence of isolated pulmonary hypertension (without ILD) was higher in those with dcSScACA (15% vs. 2%; p=0.018). No differences were found regarding survival when comparing serodiscordant patients with the seroconcordants patients. CONCLUSIONS: In our cohort, the prevalence of serodiscordant SSc patients was low. They differed from their counterparts in some clinical manifestations. The management of patients with SSc should be guided by both serology and cutaneous subtype.

OBJECTIVES: Blood pressure (BP) physiologically declines more than 10% at night. Subjects who do not experience this drop are classified as non-dippers. They have a higher risk of cardiovascular diseases (CVD). Vitamin D deficiency and non-dipper pattern have been associated in the general population. Patients with systemic lupus erythematosus (SLE) are more likely to have vitamin D deficiency, a non-dipper pattern and CVD. We aimed to evaluate a possible relationship between vitamin D deficiency and non-dipper pattern in patients with SLE. METHODS: Using 24-hour ambulatory BP monitoring, 77 women with SLE were divided into dippers and non-dippers. 25-hydroxyvitamin D (25(OH)D) levels were compared between both groups. A multivariate analysis was used to determine which variables were independently associated with non-dipper pattern. RESULTS: 62% of patients were non-dippers. They had lower levels of 25(OH)D than dippers (19.4±8.9 vs. 25.9±10.1 ng/ml, p=0.005). Patients with lower 25(OH)D levels were more likely to be non-dippers (OR 3.7, 95%CI 1.2-11.4; p=0.025). The nocturnal decline of mean BP correlated with levels of 25(OH)D (r=0.227, p=0.047). Night-time systolic, diastolic and mean BP inversely correlated with the levels of 25(OH)D (r=-0.274, p=0.016; r=-0.238, p=0.037, and r=-0.260, p=0.022, respectively), but only night- time systolic BP remained significant after adjustment for age and body mass index (r=-0.228, p=0.049). 25(OH)D levels and the use of mycophenolate were found to be independently associated with non-dipper pattern in SLE patients. CONCLUSIONS: Vitamin D deficiency may contribute to the development of a non-dipper pattern in patients with SLE.

Background and objectives: Higher physical fitness is associated with a more favorable weight and body composition in the general population, although this association has not been studied in patients with systemic lupus erythematosus (SLE). The aim of the present study was to examine the association of different components of physical fitness with body composition in women with SLE with mild disease activity. Materials and Methods: This cross-sectional study included 77 women with SLE (43.2 ± 13.8 years old) and clinical stability during the previous 6 months. Body composition (including body mass index (BMI), fat mass index (FMI), waist circumference, waist-to-height ratio and waist-to-hip ratio) was assessed using a stadiometer, an anthropometric tape, and a bioimpedance device. Physical fitness included cardiorespiratory fitness (Siconolfi step test and 6 min walk test), muscular strength (handgrip strength test as upper body measure and 30 s chair stand as lower body measure), and flexibility (back-scratch test). Participants with a fitness level equal or above the median of the study sample were categorized as "fit" and those below the median were categorized as "unfit". Linear regression assessed the association of physical fitness with body composition parameters. Results: Cardiorespiratory fitness and upper body muscular strength were negatively associated with BMI, FMI, waist circumference, and waist-to-height ratio (all, p < 0.05). Lower body muscular strength and flexibility were negatively related to FMI, waist circumference, waist-to-height ratio, and waist-to-hip ratio (all, p < 0.05). These relationships were still significant after controlling for age, disease duration, accrual damage, and SLE activity. Overall, fit patients presented significantly lower values in all body composition parameters compared to unfit patients (all, p < 0.05). Conclusions: The main findings of the present study suggest that physical fitness is inversely associated with body composition in women with SLE. Given the cross-sectional nature of this study, future clinical trials should study the causal pathways underlying these relationships.

OBJECTIVES: To determine the changes in the pattern of death of patients with systemic sclerosis (SSc) throughout 20 years. METHODS: Data were collected from the Spanish Scleroderma Registry (RESCLE), retrospective multicentre database from 1990 to 2009. SSc-related and SSc-non related causes of death were assessed. RESULTS: 987 patients were recruited. Overall standardised mortality ratio (SMR) was 2.34 (2.24-2.44). SSc-related causes of death were responsible of 72% of all deaths of those patients diagnosed within 1990-99 vs. 48% within 2000-09 (p=0.006). Relative pulmonary death rate was stable over time (68.1% within 1990-99 vs. 63.9% within 2000-09, p=0.815). Relative renal death rate was decreasing over time (17% within 1990-99 vs. 5.5% within 2000-09, p=0.175). Heart distribution tripled its ratio (12.8% within 1990-99 vs. 30.6% within 2000-09, p=0.058). CONCLUSIONS: SSc-related causes of death were decreasing over time and, among them, pulmonary involvement was the leading cause of death in both decades. The ratio of renal causes decreased since 1990 at the time that the ratio of cardiac causes increased.

OBJECTIVES: The low overall prevalence of systemic sclerosis (SSc) and the low proportion of male patients have resulted in a scarcity of studies assessing sex differences in Ssc patients, and contradictory results have often been show among those studies that have been performed. METHODS: A prospective study was conducted with the Spanish RESCLE register to analyse the influence of gender on survival of SSc patients. RESULTS: In total, 1506 SSc patients (1341 women, 165 men) were recruited from 21 centres. Older age at onset (OR 1.02), shorter time from onset to diagnosis (OR 0.96), smoking (OR 2.57), interstitial lung disease (ILD) (OR 1.58), less predisposition to sicca syndrome and to antinuclear antibody positivity (OR 0.29 and 0.43, respectively), and higher compliance with the ACR 1980 criteria (OR 1.79) were independently associated with the male sex. During follow-up, 30.4% of men versus 14.6% of women died (p<0.001). Survival at 10 years from the onset of symptoms was 75.3% for men and 92.9% for women (p<0.001), and the difference remained after selecting only SSc-related deaths (85.6% vs. 96.1%, p<0.001). The mortality predictive factors were diffuse SSc (OR 2.26), ILD (OR 1.82), digital ulcers (OR 1.38), tendon friction rubs (OR 1.74), male sex (OR 1.53), increased age at onset (OR 1.13) and isolated PH (considering only deaths from diagnosis), both in the overall (OR 3.63) and female cohorts (OR 3.97). The same risk factors were observed in the male cohort, except for isolated PH and ILD. CONCLUSIONS: The present study confirms the existence of epidemiological, clinical, laboratory and prognostic gender differences in systemic sclerosis patients.

OBJECTIVES: To assess the clinical manifestations and prognosis of Spanish patients with systemic sclerosis (SSc) according to their immunological profile. METHODS: From the Spanish Scleroderma Study Group or RESCLE (Registro de ESCLErodermia as Spanish nomenclature) Registry we selected those patients in which anti-centromere (ACA), anti-topoisomerase I (ATA), and anti-RNA polymerase III (ARA) antibodies had been determined, and a single positivity for each SSc specific antibody was detected. Demographic, clinical, laboratory, and survival data were compared according to the serologic status of these antibodies. RESULTS: Overall, 209 SSc patients were included. In 128 (61%) patients ACA was the only positive antibody, 46 (22%) were only positive for ATA, and 35 (17%) for ARA. Of note, the three groups were mutually exclusive. In univariate analysis, patients with ACA presented more frequently limited cutaneous SSc (lcSSc) (p<0.001), whereas diffuse cutaneous SSc (dcSSc) was the most frequent subtype in patients with ATA (54%) and ARA (62%) (both p<0.001). Positive patients for ARA showed the highest prevalence of joint involvement (p<0.001) and those from ATA group had a higher prevalence of interstitial lung disease (ILD) (p<0.001). Scleroderma renal crisis was more frequent in the ARA group (p<0.001). In multivariate analysis, ACA were associated with female gender and were protective for dcSSc and ILD. ATA were found to be protective for lcSSc and they were independently associated with interstitial reticular pattern. ARA positivity was independently associated with dcSSc. We did not find differences in mortality between the three groups. CONCLUSIONS: In Spanish SSc patients, the presence of SSc specific antibodies conferred a distinctive clinical profile.

OBJECTIVES: To determine whether there is an association between cumulated organ damage and arterial stiffness in women with systemic lupus erythematosus (SLE) with normal renal function and without renal damage. METHODS: Eighty-eight SLE women with normal renal function and without renal damage, and 102 sex- and age-matched controls with no history of coronary heart disease or peripheral arterial disease were studied. Cumulated organ damage and arterial stiffness were measured using the SLICC/ACR Damage Index (SDI) and pulse wave velocity (PWV), respectively. Patients were categorised as with (SDI ≥1) or without cumulated organ damage (SDI=0) and bivariate analyses were performed to compare both groups. A multivariate logistic regression was carried out to analyse the independent factors associated with cumulated organ damage. A multiple linear regression analysis was used to investigate the correlation between SDI and PWV, adjusted for appropriate confounders. RESULTS: PWV was significantly higher in patients with respect to controls (p=0.007). Also, patients with SDI ≥1 had significantly higher PWV than those with SDI=0 (p=0.007). In the multivariate analysis, cumulated organ damage was significantly associated with PWV (p=0.006) and obesity (p=0.003). Furthermore, PWV correlated with SDI after adjustment for age, SLE duration, systolic blood pressure, body mass index, renal function, prednisone and homocysteine (r=0.283, p=0.011). Patients with increased PWV were more likely to have organ damage (SDI ≥1) than those with normal PWV (67% vs. 36%, p=0.023). CONCLUSIONS: Cumulated organ damage was found to be independently associated with the arterial stiffness in SLE women without renal involvement.

OBJECTIVES: The current knowledge of the influence of systemic sclerosis (SSc) risk loci in the clinical sub-phenotypes is still limited. The main limitation lies in the low frequency of some sub-phenotypes which could be solved by replication studies in independent cohorts and meta-analysis between studies. In this regard, CCR6 gene variants have been recently associated with anti-topoisomerase I positive (ATA+) production in SSc patients in a candidate gene study. This gene has been proposed to have a critical role in IL-17-driven autoimmunity in human diseases. METHODS: In order to confirm the association between CCR6 and ATA+ SSc patients, we performed an independent replication study in populations of European ancestry. We studied two CCR6 genetic variants (rs968334 and rs3093024) in a total of 901 ATA+ SSc cases, 3,258 ATA- SSc cases and 7,865 healthy controls and compared allelic frequencies for those SNPs in ATA+ SSc with healthy controls and also with ATA- SSc patients. RESULTS: The comparison performed between ATA+ SSc patients and healthy controls showed significant association with SNP rs968334 (p=4.88x10(-2), OR=1.11). When we compared ATA+ SSc cases with ATA- SSc, both SNPs, rs3093024 and rs968334, showed significant associations (p=2.89x10(-2), OR=1.13; p=1.69x10(-2), OR=1.15). Finally, in order to increase even more sample size and statistical power, we meta-analysed our study with the previous reported and found a significant association between SNP rs3093024 and ATA+ SSc patients (p=1.00x10(-4), OR=1.16) comparing with healthy controls. CONCLUSIONS: Our work confirms the association of CCR6 gene and ATA+ SSc patients.

INTRODUCTION: Cardiovascular (CV) diseases are among the main causes of death in systemic lupus erythematosus (SLE). Physical activity (PA) and fitness are potential protective factors against the progression of CV risk factors and atherosclerosis. AIM: To analyze trends over time in PA, sedentary time (ST) and physical fitness and their associations of with traditional and novel markers of CV risk and subclinical atherosclerosis in women with SLE over a 3-year follow-up period. METHODS: In this exploratory study, 77 White Hispanic women with SLE (43.3±13.8 years) with mild disease activity were followed after 3 years (n=44). HDL and LDL cholesterol (blood samples), BMI and muscle mass (stadiometer and bioimpedance device), blood pressure (BP), pulse wave velocity (PWV, Mobil-O-Graph® monitor), carotid plaques and intima-media thickness (General Electric Medical Systems, LOGQ-6 model) were assessed. PA and ST were measured using triaxial accelerometers. Physical fitness was assessed with the back-scratch, handgrip strength, 30-s chair stand, and 6-min walk, tests. RESULTS: After 3 years, LDL-c (estimated mean change [est]=13.77mg/dL) and PWV (0.13m/s) increased while diastolic BP (-2.80mmHG) decreased (all, p<0.05). In mixed models, 6-min walk test was positively associated with HDL-c (est=0.07); back scratch (est=0.33) and chair-stand (est=1.19) tests were positively associated with systolic BP (all, p<0.05). No other trends or associations over time were identified (all, p>0.05). CONCLUSIONS: PA, ST, fitness, and most studied CV risk factors remained stable over time, with only marginal changes in LDL-c, PWV, and diastolic BP. Overall, PA and ST were not longitudinally associated with CV risk factors and subclinical atherosclerosis and contradictory weak associations were found for physical fitness.
RESUMO
Systemic Lupus Erythematosus (SLE) is a chronic autoimmune disease linked to high cardiovascular risk. To reach an adequate body composition status while maintaining proper dietary habits are effective strategies for reducing cardiovascular risk, both being potentially modified through exercise. This study aimed to evaluate the effects of a 12-week aerobic training intervention on anthropometry, body composition and adherence to the Mediterranean diet in women with SLE. A total of 58 women with SLE were assigned to either an exercise group (EG; n = 26) or a comparison group (CG; n = 32) in this non-randomized controlled trial. The EG comprised 12 weeks of aerobic exercise (two sessions/week) between 40-75% of the individual's heart rate reserve (calculated as maximum heart rate - resting heart rate) and the CG received usual care. At baseline and after the intervention, the anthropometry (i.e., weight, waist circumference, waist-to-hip ratio, and body mass index) and body composition (i.e., fat mass and lean mass) were assessed using a stadiometer, an anthropometric tape, and a bioimpedance device, respectively. Dietary habits were assessed with the Mediterranean Diet score. There were no between-group differences in neither anthropometric nor body composition parameters (all p > 0.05). Similarly, no between-group differences were obtained in the adherence to the Mediterranean diet after the exercise intervention (all p > 0.05). Contrary to the initial hypothesis, these results suggest that the 12-week aerobic training intervention performed in this study did not improve anthropometry, body composition or adherence to the Mediterranean diet in women with SLE.

PURPOSE: To evaluate the effects of aerobic exercise on patient-reported outcomes (PROs) in women with systemic lupus erythematosus (SLE), and whether changes in cardiorespiratory fitness (CRF) mediate the changes in PROs. METHODS: A total of 58 women with SLE were assigned to either an exercise group (EG; n = 26) or a control group (CG; n = 32) in this non-randomized clinical trial. The EG comprised 12 weeks of aerobic exercise (2 sessions/week) between 40%-75% of the individual's heart rate reserve. At baseline, and at week 12, CRF (Bruce test) and PROs were assessed including psychological stress (Perceived Stress Scale), sleep quality (Pittsburg Sleep Quality Index), fatigue (Multidimensional Fatigue Inventory), depressive symptoms (Beck Depression Inventory), and quality of life (36-item Short-Form Health Survey). RESULTS: In comparison to the CG, the EG showed a significant reduction in general fatigue (mean difference (MD) -2.86 units; 95%CI -5.70 to -0.01; p = 0.049), physical fatigue (MD -4.33 units; 95%CI -7.02 to -1.65; p = 0.002) and a non-significant reduction of reduced motivation (MD - 1.29 units; 95%CI -2.60 to 0.03; p = 0.055). There were no significant between-group differences in the changes in psychological stress, sleep quality, depressive symptoms, quality of life, or other fatigue dimensions (all p > 0.05). Changes in CRF mediated the effects of the exercise intervention on general fatigue by 53.8%. CONCLUSION: The results suggest that 12 weeks of progressive aerobic exercise might improve relevant dimensions of fatigue in women with SLE, despite the absence of effects on other PROs. Improvements in CRF seem to mediate the effect of exercise on general fatigue.Implications for rehabilitationAerobic exercise could be safely introduced in rehabilitation programs for inactive patients with SLE with mild disease activity.Including physical activity recommendations as part of rehabilitation could improve relevant aspects of fatigue in women with SLE.When rehabilitation aims at reducing fatigue, cardiorespiratory fitness improvements derived from physical activity might enhance benefits.

AIM: Patients with systemic sclerosis (SSc) are at increased risk of cancer, a growing cause of non-SSc-related death among these patients. We analyzed the increased cancer risk among Spanish patients with SSc using standardized incidence ratios (SIRs) and identified independent cancer risk factors in this population. MATERIAL AND METHODS: Spanish Scleroderma Registry data were analyzed to determine the demographic characteristics of patients with SSc, and logistic regression was used to identify cancer risk factors. SIRs with 95% confidence intervals (CIs) relative to the general Spanish population were calculated. RESULTS: Of 1930 patients with SSc, 206 had cancer, most commonly breast, lung, hematological, and colorectal cancers. Patients with SSc had increased risks of overall cancer (SIR 1.48, 95% CI 1.36-1.60; P < 0.001), and of lung (SIR 2.22, 95% CI 1.77-2.73; P < 0.001), breast (SIR 1.31, 95% CI 1.10-1.54; P = 0.003), and hematological (SIR 2.03, 95% CI 1.52-2.62; P < 0.001) cancers. Cancer was associated with older age at SSc onset (odds ratio [OR] 1.22, 95% CI 1.01-1.03; P < 0.001), the presence of primary biliary cholangitis (OR 2.35, 95% CI 1.18-4.68; P = 0.015) and forced vital capacity <70% (OR 1.8, 95% CI 1.24-2.70; P = 0.002). The presence of anticentromere antibodies lowered the risk of cancer (OR 0.66, 95% CI 0.45-0.97; P = 0.036). CONCLUSIONS: Spanish patients with SSc had an increased cancer risk compared with the general population. Some characteristics, including specific autoantibodies, may be related to this increased risk.

OBJECTIVES: Left ventricular diastolic dysfunction (LVDD) remains poorly studied in Systemic Sclerosis (SSc). To determine the prevalence and to define factors associated with LVDD and survival in a large cohort of patients with SSc. METHODS: An observational study was conducted with data from the multicentre Spanish Scleroderma Registry (RESCLE) to identify factors associated with LVDD and estimate survival. RESULTS: Out of 1517 patients, 319 (21.0%) had LVDD. The subset of sine scleroderma SSc was associated to LVDD (14.7% vs. 10.6%, p =0.048), whilst diffuse cutaneous SSc was more prevalent in non-LVDD (16.0 % vs. 21.2%, p =0.041). Multivariable analysis identified that LVDD was associated with older age at diagnosis of SSc (OR 1.05; 95% CI 1.04 to 1.06), longer time from diagnosis (OR 1.04; 95% CI 1.03 to 1.06), presence of telangiectasia (OR 1.42; 95% CI 1.08 to 1.88), treatment with calcium channel blockers (CCB) (OR 1.51; 95% CI 1.16 to 1.96), and inversely related to angiotensin-converting-enzyme inhibitors (ACEi) use (OR 0.59; 95% CI 0.44 to 0.80). SSc patients with LVDD had increased mortality (23.8 vs. 17.4%, p =0.010) and shortened survival from the first SSc symptom (p =0.040), even though it was not found to be an independent risk factor for death. CONCLUSIONS: LVDD is relatively common in SSc patients, and it is associated with worst prognosis, older age, longer time from diagnosis of SSc, presence of telangiectasia and vasodilator treatment.

OBJECTIVE: Evaluation of the effectiveness and safety of long-term low molecular weight heparin (LMWH) in patients with antiphospholipid syndrome (APS) that had not previously responded to or tolerated oral vitamin K antagonists. METHODS: 23 patients with confirmed diagnosis of APS were retrospectively recruited. All patients were receiving LMWH as a result of intolerance and/or lack of response to warfarin therapy. The type of LMWH, the duration of treatment, the reason for switching to LMWH and the adverse effects were recorded. Outcomes were classified as no improvement, partial improvement or total improvement after at least 1 year of using LMWH. RESULTS: The average duration of LMWH treatment was 36 months. Most of the patients were on treatment with enoxaparin (n=16, 69%) and were switched to LMWH from warfarin mainly because of thrombosis despite therapeutic international normalised ratio (n=9, 39%). Good quality of life with no evidence of recurrent thrombotic events was noted in nine patients (39%), whereas 11 (48%) showed partial clinical improvement but no evidence of recurrent thrombotic episodes. Osteoporosis was reported in five patients (23%), all of whom were also receiving treatment with corticosteroids. CONCLUSIONS: Long-term LMWH may be a safe and effective alternative to warfarin for APS patients.

Aims: Higher body mass and adiposity represent independent contributors to the systemic low-grade inflammatory state often observed in patients with systemic lupus erythematosus (SLE). This study assessed the role of physical fitness in the association of body mass and adiposity with inflammation in women with SLE. Methods: A total of 77 women with SLE were included in this cross-sectional study. We obtained body mass index, waist-to-height ratio, and body fat percentage as indicators of body mass and adiposity. Inflammation was assessed through Serum levels of C-reactive protein, interleukin 6, and leptin. Cardiorespiratory fitness was assessed with the 6-minute walk test, range of motion with the back-scratch test, and muscular strength with handgrip dynamometry. Results: Cardiorespiratory fitness attenuated the association of both body mass index and body fat percentage with interleukin 6 (all, P<0.05). Range of motion attenuated the association of body mass index with interleukin 6 (P<0.05) and the association of body fat percentage with C-reactive protein (P<0.05). These interactions indicated that higher fitness was associated with a lower increase in inflammation per unit increase of body mass or adiposity. Muscular strength showed a non-significant trend to attenuate the association of body fat percentage with interleukin 6 (P=0.057) but potentiated the association of body fat percentage with leptin (P<0.05). Conclusion: These findings suggest that higher levels of cardiorespiratory fitness and range of motion might attenuate the impact of higher body mass and adiposity on inflammation in women with SLE. The role of muscular strength requires further investigation.
