RESUMEN
BACKGROUND: The aim of this study was twofold: (i) to examine the association of cardiorespiratory fitness with arterial stiffness in women with systemic lupus erythematosus; (ii) to assess the potential interaction of cardiorespiratory fitness with age on arterial stiffness in this population. MATERIALS AND METHODS: A total of 49 women with systemic lupus erythematosus (mean age 41.3 [standard deviation 13.8] years) and clinical stability during the previous 6 months were included in the study. Arterial stiffness was assessed through pulse wave velocity (Mobil-O-Graph® 24 hours pulse wave velocity monitor). Cardiorespiratory fitness was estimated with the Siconolfi step test and the 6-minute walk test. RESULTS: Cardiorespiratory fitness was inversely associated with pulse wave velocity in crude analyses (P < .05), although this relationship was attenuated when age and other cardiovascular risk factors were controlled. There was a cardiorespiratory fitness × age interaction effect on pulse wave velocity, regardless of the test used to estimate cardiorespiratory fitness (P < .001 for the Siconolfi step test; P = .005 for the 6-minute walk test), indicating that higher cardiorespiratory fitness was associated with a lower increase in pulse wave velocity per each year increase in age. CONCLUSIONS: The results of this study suggest that cardiorespiratory fitness might attenuate the age-related arterial stiffening in women with systemic lupus erythematosus and might thus contribute to the primary prevention of cardiovascular disease in this population. As the cross-sectional design precludes establishing causal relationships, future clinical trials should confirm or contrast these findings.

BACKGROUND: Systemic Lupus Erythematosus (SLE) is closely related to cardiovascular morbidity and mortality. We aimed to examine the association of ideal cardiovascular health (ICH) with arterial stiffness, inflammation, and physical fitness in women with SLE. METHODS: This cross-sectional study included 76 women with SLE (age 43.4±13.8 years old). Ideal levels of 7 health metrics (smoking, body mass index, physical activity, healthy diet, blood pressure, cholesterol, and glucose) were used to define the ICH score (ranging from 0 to 7 ideal metrics) and the ICH status ( defined as presenting ≥4 ideal metrics). Arterial stiffness was measured through pulse wave velocity (PWV) and inflammation through serum high sensitivity C-reactive protein (hs-CRP). Cardiorespiratory fitness (CRF) was measured by 6-min walk test (6MWT), and Siconolfi step test and muscular strength by handgrip strength and 30-s chair stand, and range of motion (ROM) by the back-scratch test. RESULTS: Higher ICH score was associated with lower PWV (ß = -0.122, p = 0.002), lower hs-CRP (ß = -0.234, p = 0.056), higher CRF [6MWT (ß = 0.263, p = 0.041); Siconolfi step test (ß = 0.330, p < 0.001)], higher ROM (ß = 0.278, p = 0.013) and higher relative handgrip strength (ß = 0.248, p = 0.024). Women with ICH status presented lower PWV (mean difference 0.40 m/s, 95% CI 0.17 to 0.63, p = 0.001), and higher CRF [assessed by 6MWT (mean difference 43.9 m, 95% CI 5.0 to 82.7, p = 0.028)], than women with non-ICH status. Sensitivity analyses using ICH score ranging 0-14 and considering ICH status with ≥5 metrics revealed consistent results. CONCLUSION: ICH is associated with lower arterial stiffness, lower inflammation, and higher fitness in women with SLE. Although these results extend current knowledge about the potential role of ICH for primordial prevention of CVD in SLE, they are yet to be confirmed in future prospective research .

BACKGROUND: Severe and morbid obesity are increasing globally, particularly in women. As BMI increases, the likelihood of anovulation is higher. The primary aim of the EMOVAR clinical trial is to examine, over the short (16 weeks) and medium (12 months) term, the effects of a supervised physical exercise program (focused primarily on aerobic and resistance training) on ovarian function in women with severe/morbid obesity who have undergone bariatric surgery. Secondary objectives are to examine the effects of the intervention on chronic inflammation, insulin resistance, arterial stiffness, physical fitness, and health-related quality of life. METHODS: This is a randomized controlled trial in which â¼40 female bariatric surgery patients, aged between 18 and 45 years old, will be included. Participants assigned to the experimental group will perform a total of 48 sessions of supervised concurrent (strength and aerobic) training (3âsessions/week, 60âmin/session) spread over 16 weeks. Patients assigned to the control group will receive lifestyle recommendations. Outcomes will be assessed at baseline, week 16 (i.e., after the exercise intervention) and 12 months after surgery. The primary outcome is ovarian function using the Sex-Hormone Binding Globuline, measured in serum. Secondary outcomes are serum levels of anti-mullerian hormone, TSH, T4, FSH, LH, estradiol, prolactine, and free androgen index, as well as oocyte count, the diameters of both ovaries, endometrial thickness, and uterine arterial pulsatility index (obtained from a transvaginal ultrasound), the duration of menstrual bleeding and menstrual cycle duration (obtained by personal interview) and hirsutism (Ferriman Gallwey Scale). Other secondary outcomes include serum markers of chronic inflammation and insulin resistance (i.e., C-reactive protein, interleukin 6, tumor necrosis factor-alpha, leptin, glomerular sedimentation rate, glucose, insulin and the HOMA-IR), arterial stiffness, systolic, diastolic and mean blood pressure, body composition, and total weight loss. Physical fitness (including cardiorespiratory fitness, muscular strength, and flexibility), health-related quality of life (SF-36 v2) and sexual function (Female Sexual Function Index) will also be measured. DISCUSSION: This study will provide, for the first time, relevant information on the effects of exercise training on ovarian function and underlying mechanisms in severe/morbid obese women following bariatric surgery. TRIAL REGISTRATION NUMBER: ISRCTN registry (ISRCTN27697878).

OBJECTIVES: To study the association of different components of physical fitness [flexibility, muscle strength and cardiorespiratory fitness (CRF)] and a clustered fitness score with health-related quality of life (HRQoL) in women with systemic lupus erythematosus (SLE) and to analyze whether participants with high fitness level have better HRQoL. METHODS: This cross-sectional study included 70 women with SLE (aged 42.5; SD 13.9 years). The back-scratch test assessed flexibility, the 30-sec chair stand and handgrip strength tests assessed muscle strength, and the 6-min walk test (n = 49) assessed CRF. HRQoL was assessed through the 36-item Short-Form Health Survey (SF-36). RESULTS: Flexibility was positively associated with the physical function dimension and the physical component summary (PCS) (rpartial between 0.26 and 0.31; p<0.05), and negatively related with social functioning dimension (rpartial = -0.26; p<0.05). Muscle strength was positively associated with the physical function, physical role, bodily pain dimensions and the PCS (rpartial between 0.27 and 0.49; all p<0.05). CRF was positively associated with the physical function and bodily pain dimensions, and PCS (rpartial between 0.39 and 0.65; all p<0.05). The clustered fitness score was associated with the physical function (B = 17.16) and bodily pain (B = 14.35) dimensions, and the PCS (B = 6.02), all p<0.005. Patients with high fitness level had greater scores in the physical function, physical role, and bodily pain dimensions and the PCS, all p≤0.05. CONCLUSIONS: Our study suggests that muscle strength and CRF are positively associated with HRQoL, while flexibility showed contradictory results. These findings highlight the importance of maintaining adequate fitness levels in women with SLE.

INTRODUCTION: Our objective was to evaluate the pulmonary hypertension (PH) data for Spanish patients with systemic sclerosis (SSc), define the PH types and determine the associated factors. METHOD: Descriptive study of PH-related data from the multicentre RESCLE registry. Estimated systolic pulmonary artery pressure (esPAP), measured via echocardiogram was considered elevated if ≥ 35 mmHg. Left heart disease (LHD) and interstitial lung disease (ILD) were identified. When performed, data from right heart catheterisation (RHC) were collected. RESULTS: esPAP was elevated in 350 of 808 patients (43.3%). One hundred and forty-four patients (17.8%) were considered to have PH (88 via RHC and the rest due to elevated esPAP along with evidence of significant LHD or ILD): PAH 3.7%, secondary to ILD 8.3%, secondary to LHD 2.8% and unclassified 3%. Prevalence of elevated esPAP was greater in diffuse SSc (dSSc) than in limited scleroderma (lSSc) (50.5 vs. 42.2%, p 0.046). In the group with elevated esPAP, a lower prevalence of anti-centromere antibodies (41.9% vs. 52.3%, p 0.006) and a greater prevalence of anti-topoisomerase-1 antibodies (ATA) (25.1% vs. 18.6%, p 0.04) were observed compared to the group with normal esPAP. Patients with elevated esPAP had a lower rate of digital ulcers (50.6% vs. 60.2%, p 0.007) and esophageal involvement (83.6% vs. 88.7%, p 0.07) and higher rate of renal crisis (4.6% vs. 1.8%, p 0.066). CONCLUSIONS: Prevalence of PAH was lower than expected (3.7%). Probability of having elevated esPAP was higher among patients with dSSc and among those with ATA.

OBJECTIVES: To examine the association of objectively measured physical activity (PA) intensity levels and sedentary time with arterial stiffness in women with systemic lupus erythematosus (SLE) with mild disease activity and to analyze whether participants meeting the international PA guidelines have lower arterial stiffness than those not meeting the PA guidelines. METHODS: The study comprised 47 women with SLE (average age 41.2 [standard deviation 13.9]) years, with clinical and treatment stability during the 6 months prior to the study. PA intensity levels and sedentary time were objectively measured with triaxial accelerometry. Arterial stiffness was assessed through pulse wave velocity, evaluated by Mobil-O-Graph® 24h pulse wave analysis monitor. RESULTS: The average time in moderate to vigorous PA in bouts of ≥10 consecutive minutes was 135.1±151.8 minutes per week. There was no association of PA intensity levels and sedentary time with arterial stiffness, either in crude analyses or after adjusting for potential confounders. Participants who met the international PA guidelines did not show lower pulse wave velocity than those not meeting them (b = -0.169; 95% CI: -0.480 to 0.143; P = 0.280). CONCLUSIONS: Our results suggest that PA intensity levels and sedentary time are not associated with arterial stiffness in patients with SLE. Further analyses revealed that patients with SLE meeting international PA guidelines did not present lower arterial stiffness than those not meeting the PA guidelines. Future prospective research is needed to better understand the association of PA and sedentary time with arterial stiffness in patients with SLE.

AIM: To determine if there are ethnic differences in the prevalence of antiphospholipid syndrome (APS), clinical presentation and autoantibody profile between Roma and Caucasian patients with systemic lupus erythematosus (SLE). METHOD: A cross-sectional study was conducted including data from Roma and Caucasian SLE patients consecutively attending six hospitals in Spain. Socio-demographic characteristics, prevalence of APS, clinical and analytical features of SLE and APS were compared between ethnic groups. RESULTS: Data from 52 Roma and 98 Caucasian SLE patients were included. Roma SLE patients had a higher risk (odds ratio 2.56, 95% CI 1.02-6.39) and prevalence of APS (28.8% vs. 13.3%, P = 0.027). Furthermore, Roma SLE patients had a statistically significant higher prevalence of abortions (23.5% vs. 10.2%, P = 0.049). In relation to other APS diagnostic criteria, Roma SLE patients had a non-statistically significant higher prevalence of fetal deaths (14.3% vs. 5.1%, P = 0.106) and thrombotic events (21.1% vs. 12.2%, P = 0.160). In relation to SLE clinical features, Roma patients had a significantly higher prevalence of arthritis (75% vs. 57.1%, P = 0.034) and non-significant higher prevalence of serositis (44.2% vs. 29.6%, P = 0.104), discoid lesions (11.5% vs. 5.1%, P = 0.191), oral ulcers (46.1% vs. 34.7%, P = 0.218) and livedo reticularis (21.1% vs. 15.3%, P = 0.374). No statistically significant differences were found in the Systemic Lupus International Collaborating Clinics Damage Index or the autoimmune serological profile. CONCLUSION: Prevalence and risk of APS were significantly higher in Roma SLE patients. Furthermore, Roma patients had a significantly higher prevalence of abortions and a non-significant higher prevalence of fetal deaths and thrombotic events.

OBJECTIVE: Digital ulcers (DU) are the most common vascular complication of systemic sclerosis (SSc). We compared the characteristics between patients with prior or current DU with those never affected and evaluated whether a history of DU may be a predictor of vascular, organ involvement, and/or death in patients with SSc. METHODS: Data from SSc patients with or without prior or current DU were collected by 19 referral centers in an ongoing registry of Spanish SSc patients, named Registro de ESCLErodermia (RESCLE). Demographics, organ involvement, autoimmunity features, nailfold capillary pattern, survival time, and causes of death were analyzed to identify DU related characteristics and survival of the entire series and according to the following cutaneous subsets-diffuse cutaneous SSc (dcSSc), limited cutaneous SSc (lcSSc), and SSc sine scleroderma (ssSSc). RESULTS: Out of 1326, 552 patients enrolled in the RESCLE registry had prior or current DU, 88% were women, the mean age was 50 ± 16 years, and the mean disease duration from first SSc symptom was 7.6 ± 9.6 years. Many significant differences were observed in the univariate analysis between patients with and without prior/current DU. Multivariate analysis identified that history of prior/current DU in patients with SSc was independently associated to younger age at SSc diagnosis, diffuse cutaneous SSc, peripheral vascular manifestations such Raynaud's phenomenon, telangiectasia, and acro-osteolysis but no other vascular features such as pulmonary arterial hypertension or scleroderma renal crisis. DU was also associated to calcinosis cutis, interstitial lung disease, as well as worse survival. Multivariate analysis performed in the cutaneous subsets showed that prior/current DU were independently associated: (1) in dcSSc, to younger age at SSc diagnosis, presence of telangiectasia and calcinosis and rarely a non-SSc pattern on nailfold capillaroscopy; (2) in lcSSc, to younger age at SSc diagnosis, presence of Raynaud's phenomenon as well as calcinosis cutis, interstitial lung disease, and higher incidence of death from all causes; and (3) in ssSSc, to younger age at first SSc symptom and greater incidence of death from all causes. CONCLUSIONS: Digital ulcers develop in patients with SSc younger at diagnosis, mainly in patients with dcSSc and lcSSc, and they are associated to other peripheral vascular manifestations such as Raynaud's phenomenon, telangiectasia, and acro-osteolysis but also to calcinosis, and interstitial lung disease. History of DU in SSc leads to worse survival, also noticeable for lcSSc and ssSSc subsets but not for dcSSc patients.
