Show moreBackground: Since 2009, Dutch patients with a confirmed diagnosis/suspicion of systemic sclerosis (SSc) can be referred to the Leiden Combined Care in Systemic Sclerosis (CCISS) cohort. This study evaluated whether early recognition of SSc has improved over time and whether disease characteristics and survival has changed over time. Methods: 643 SSc patients fulfilling American College of Rheumatology/European Alliance of Associations for Rheumatology 2013 SSc criteria were included and categorised into three groups based on cohort-entry year: (1) 2010-2013 (n=229 (36%)), (2) 2014-2017 (n=207 (32%)) and (3) 2018-2021 (n=207 (32%)). Variables including disease duration, interstitial lung disease (ILD), digital ulcers (DU), diffuse cutaneous SSc (dcSSc), antitopoisomerase (ATA) and anticentromere (ACA) antibodies, and survival from disease onset were compared between cohort-entry groups, including analyses stratified for sex and autoantibodies. Results: Over time, duration between onset of disease symptoms and cohort entry decreased in males and females, but was always longer in females than in males.The proportion of patients presenting with DU decreased, especially in ACA+SSc patients. Almost no ACA+ patients presented with ILD, while in ATA+ patients this proportion was 25% in 2010-2013 and decreased to 19% in 2018-2021. A reduction in patients presenting with clinically meaningful ILD and dcSSc was observed.Overall 8-year survival for males was 59% (95% CI 40% to 73%) and for females 89% (95% CI 82% to 93%). Eight-year survival showed a trend for improvement over time, and was always worse in males. Conclusion: We observed a decrease in disease duration in Leiden CCISS cohort at cohort entry, possibly indicating more timely diagnosis of SSc. This could provide opportunities for early interventions. While symptom duration at presentation is longer in females, mortality is consistently higher in males, underlining the urge for sex-specific treatment and follow-up. Show less

Show moreObjective Hematopoietic stem cell transplantation (HSCT) and cyclophosphamide (CYC) are treatment options for progressive systemic sclerosis associated with interstitial lung disease (SSc-ILD). The aims of our retrospective observational study were to evaluate: 1) the evolution of SSc-ILD in SSc patients treated with HSCT (assessed by high-resolution computed tomography [HRCT]; a group of patients treated with CYC was included as frame of reference); 2) how results of pulmonary function tests (PFTs) are associated with HRCT findings; and 3) which factors predict ILD reduction. Methods We semiquantitatively scored total ILD extent, reticulations, and ground-glass opacities (GGO) scores at baseline and at the 1-year HRCTs of SSc patients treated with HSCT or CYC. Linear association between changes in HRCT scores and PFT results and predictors of ILD improvement were studied. Results We included 51 patients (those treated with HSCT [n = 20] and those treated with CYC [n = 31]). The mean change in total ILD score was -5.1% (95% confidence interval [95% CI] -10.2, 0.0) in the HSCT treatment group (P = 0.050), and -1.0% (95% CI -4.3, 2.3) in the CYC treatment group (P = 0.535). For all patients, the evolution of HRCT scores was weakly associated with relative changes in PFT results. In univariate logistic regression, higher ground-glass opacities, higher total ILD, and lower single-breath diffusing capacity for carbon monoxide scores at baseline predicted improvement of ILD extent after treatment, but a multivariable model could not be built to assess independency of predictors. Conclusion One year after treatment with HSCT, a nonsignificant but clear reduction of SSc-ILD extent was observed. Changes in PFT results were associated with changes in HRCT scores but the correlation was weak and cannot be considered conclusive. Show less

Show moreIn order to provide more patient-centered care for patients suffering from systemic lupus erythematosus (SLE), we studied their current satisfaction and preferences regarding future health care delivery. We sent questionnaires to all SLE patients visiting the rheumatology outpatient clinic in Leiden, the Netherlands. The questionnaire comprised three topics: (a) health care needs using a modified version of SLE Needs Questionnaire (range 0-38), (b) satisfaction with care per provider (visual analogue scale, range 0 (not at all)-100 (very satisfied)), and (c) preferences for future healthcare (four items). One hundred and two patients (63 % response) reported an average of 16 (±6) health care needs, with all patients reporting a need in the physical domain. More needs were significantly associated with worse physical functioning and a higher educational level. The average satisfaction score was 73 (±19) with a lower overall satisfaction score being associated with younger age and an educational level higher or lower than average. Regarding preferences for future health care delivery, 75 % of patients showed interest in a yearly standardized medical assessment, 57 % in regular, specialized nurse contacts using internet, 50 % in a yearly inventory on the need for self-management support, and 36 % in an education course. The association of age, education level and physical functioning with health care needs, and/or satisfaction suggest that the delivery of care should be better tailored to the needs of subgroups of patients.

Show moreThis study aims to examine healthcare utilization and its determinants among patients with systemic sclerosis (SSc). A cross-sectional survey among all patients with SSc visiting an outpatient clinic of an academic hospital in the Netherlands was done. Assessments included sociodemographic characteristics and a survey on healthcare utilization including a registration of contacts with healthcare services since onset of disease, contacts, and number of visits with healthcare services over the last 12 months. A total healthcare utilization score of all visits over the last 12 months was computed and classified as high and low care utilization according to the median. In addition, the Short Form-36 and the Scleroderma Health Assessment Questionnaire (SHAQ) were administered. Logistic regression analysis was used to determine the relationship between high and low healthcare utilization as dependent variable and sociodemographic and disease characteristics as independent variables. Sixty-four patients returned the questionnaires. Over the last 12 months, 83 % of the patients had had contact with one or more physicians. On average, patients reported 3.9 visits (SD, 2.9) to a rheumatologist and 6.9 visits (SD, 9.3) to other medical specialists over the last 12 months. The median total health-care utilization was six visits over the last 12 months. Multivariate regression showed that a higher SHAQ score was significantly associated with higher health-care utilization. Patients with SSc visited a considerable number of various health-care providers. Patients with more functional disability were using more healthcare. Show less

Show moreOBJECTIVE Systemic sclerosis (SSc) is a connective tissue disease characterized by vascular inflammation and fibrosis. Visceral involvement, including cardiac manifestations, can lead to severe clinical complications, such as congestive heart failure, arrhythmias, and sudden death. Conventional echocardiography parameters have limited sensitivity to detect subtle myocardial dysfunction in patients with SSc. The aim of this study was to assess, using novel speckle-tracking strain analysis, the presence of myocardial dysfunction in patients with SSc, and to investigate its relationship to functional capacity and ventricular arrhythmias. METHODS A total of 104 patients with SSc (mean ± SD age 54 ± 12 years, 77% female) were included and underwent cardiopulmonary exercise testing, 24-hour electrocardiography (EKG) Holter monitoring, and transthoracic echocardiography. For comparison, 37 matched healthy control subjects were included. RESULTS The total patient population consisted of 51 patients with limited cutaneous SSc and 53 with diffuse cutaneous SSc. Peak VO(2) was a mean ± SD 91 ± 20% predicted, and 28 patients had abnormal findings (ventricular tachycardia or ventricular ectopics >100/day) on EKG Holter monitoring. Patients with SSc, as compared with controls, had impaired global longitudinal and circumferential strains (mean ± SD -18.2 ± 1.8% versus -21.3 ± 1.7% and -18.2 ± 2.3% versus -21.3 ± 2.1%, respectively; each P < 0.01), but there was no difference in the left ventricular ejection fraction between patients and controls (mean ± SD 63.5 ± 7.2% versus 64.6 ± 4.4%; P = 0.20). In patients with SSc, global longitudinal and circumferential strains each correlated with the peak VO(2) (r = -0.46 and r = -0.41, respectively; both P < 0.01), and multivariate analysis confirmed the independent association of each strain measure with the peak VO(2) . Compared to SSc patients with normal results on EKG Holter monitoring, SSc patients with abnormal results showed impaired global longitudinal strains (-18.5 ± 1.5% versus -17.1 ± 2.1%; P < 0.01) and circumferential strains (-18.7 ± 2.0% versus -17.3 ± 2.5%; P = 0.01), and each strain measure was independently associated with abnormal Holter findings. CONCLUSION Speckle-tracking strain analysis can detect subtle myocardial dysfunction in patients with SSc. Importantly, decreased global longitudinal and circumferential strains are associated with lower functional capacity and rhythm disturbances in patients with SSc. Show less
