Efficacy of methylprednisolone in very early systemic sclerosis: results of the "Hit hard and early'' randomized controlled trial.

OBJECTIVE: We hypothesized that glucocorticoids would induce remission in very early Systemic Sclerosis patients by inhibition of inflammation driving the disease. We examined the efficacy and safety of methylprednisolone in very early Systemic Sclerosis. METHODS: In this trial adults with puffy fingers for less than three years, specific auto-antibodies and meeting the Very Early Diagnosis of Systemic Sclerosis criteria were randomly assigned (2:1) to methylprednisolone 1000 mg intravenously or placebo for 3 consecutive days 3 times with monthly intervals. The primary end point was nailfold capillary density at week 12. Capillary density at 52 weeks, number of megacapillaries, and patient-reported outcomes were secondary outcomes. In addition, we assessed disease progression and lung function decline over 52 weeks. We used linear regression analyses adjusted for baseline values and stratification variables to estimate differences between groups. RESULTS: Between February 2017 and February 2021, 87 patients were screened, of whom 30 (70% female, median (IQR) age 52·9 (40·8-60·8) years, median (IQR) disease duration 11.4 (4.6-18.6) months) were randomly assigned to methylprednisolone (n = 21) or placebo (n = 9). We found no difference in nailfold capillary density at 12 weeks: -0.5 (95% CI 1.1, 0.2) nor in any of the secondary outcomes. Eleven (37%) patients showed disease progression during 1 year follow up, 7 (23%) patients had a relevant pulmonary function decline. No serious adverse events were reported. CONCLUSIONS: No clinically relevant effect of short-term methylprednisolone in patients with very early Systemic Sclerosis was observed. A substantial proportion of patients showed disease progression.

Systemic sclerosis-associated pulmonary arterial hypertension is characterized by a distinct peripheral T helper cell profile.

OBJECTIVES: Systemic sclerosis (SSc) is characterized by multiple clinical manifestations. Vasculopathy is a main disease hallmark and ranges in severity from an exacerbated Raynaud phenomenon to pulmonary arterial hypertension (PAH). The potential involvement of the immune system in SSc-associated vascular abnormalities is not clear. Here, we set out to study SSc-related immune parameters and determine whether and which peripheral T cell subsets associate with vascular severity in SSc patients. METHODS: Peripheral blood and clinical data were collected from 30 SSc patients, 5 patients with idiopathic PAH and 15 age and sex-matched healthy donors (HD). In this cross-sectional cohort, SSc patients with PAH (n = 15) were matched for their age, sex and medication with SSc patients with no signs of PAH (n = 15). Lymphocyte subsets were quantified by multi-colour flow cytometry. RESULTS: SSc patients exhibited elevated percentages of T peripheral helper cells (Tph), CD4+GZMB+ T cells and decreased levels of Th1 cells compared with HD. Increased presence of both CD4+ and CD8+ exhausted-like (CD28-) T cells, characterized by raised cytokine and cytotoxic signature, was also observed in SSc compared with HD blood. Furthermore, IL-4 expressing CD4+CD8+ T cells were significantly increased in SSc peripheral blood. Interestingly, the presence of PAH in SSc was accompanied by a distinct T helper profile, characterized by raised percentages of Th17 and Tph cells. CONCLUSION: SSc patients with severe vasculopathy (presence of PAH) exhibited a distinct T cell profile, suggesting a potential role of auto-immune inflammation in SSc vascular complications.

A phase 2 trial investigating the efficacy and safety of the mPGES-1 inhibitor vipoglanstat in systemic sclerosis-related Raynaud's.

OBJECTIVE: Our objective was to test the hypothesis, in a double-blind, placebo-controlled study that vipoglanstat, an inhibitor of microsomal prostaglandin E synthase-1 (mPGES-1) which decreases prostaglandin E2 (PGE2) and increases prostacyclin biosynthesis, improves RP. METHODS: Patients with systemic sclerosis (SSc) and ≥7 RP attacks during the last screening week prior to a baseline visit were randomised to four weeks treatment with vipoglanstat 120 mg or placebo. A daily electronic diary captured RP attacks (duration and pain) and Raynaud's Condition Score, with change in RP attacks/week as primary end point. Cold challenge assessments were performed at baseline and end of treatment. Exploratory endpoints included patients' and physicians' global impression of change, Assessment of Scleroderma-associated Raynaud's Phenomenon questionnaire, mPGES-1 activity, and urinary excretion of arachidonic acid metabolites. RESULTS: Sixty-nine subjects received vipoglanstat (n = 33) or placebo (n = 36). Mean weekly number of RP attacks (baseline; vipoglanstat 14.4[SD 6.7], placebo 18.2[12.6]) decreased by 3.4[95% CI -5.8;-1.0] and 4.2[-6.5;-2.0] attacks per week (p= 0.628) respectively. All patient reported outcomes improved, with no difference between the groups. Mean change in recovery of peripheral blood flow after cold challenge did not differ between the study groups. Vipoglanstat fully inhibited mPGES-1, resulting in 57% reduction of PGE2 and 50% increase of prostacyclin metabolites in urine. Vipoglanstat was safe and well tolerated. CONCLUSION: Although vipoglanstat was safe, and well tolerated in a dose achieving full inhibition of mPGES-1, it was ineffective in SSc-related RP. Further development and evaluation of vipoglanstat will therefore be in other diseases where mPGES-1 plays a pathogenetic role.

Evaluation of left cardiac chamber function with cardiac magnetic resonance and association with outcome in patients with systemic sclerosis.

OBJECTIVE: This study aimed to determine whether lower values of feature-tracking cardiovascular magnetic resonance (CMR)-derived left atrial reservoir strain (LARS) and impaired left ventricular (LV) global longitudinal strain (GLS) were associated with the presence of symptoms and long-term prognosis in patients with SSc. METHODS: A total of 100 patients {54 [interquartile range (IQR) 46-64] years, 42% male} with SSc who underwent CMR imaging at two tertiary referral centres were included. All patients underwent analysis of LARS and LV GLS using feature-tracking on CMR and were followed-up for the occurrence of all-cause mortality. RESULTS: The median LV GLS was -21.8% and the median LARS was 36%. On multivariable logistic regression, LARS [odds ratio (OR) 0.964 per %, 95% CI 0.929, 0.998, P = 0.049] was independently associated with New York Heart Association (NYHA) class II-IV heart failure symptoms. Over a median follow-up of 37 (21-62) months, a total of 24 (24%) patients died. Univariable Cox regression analysis demonstrated that LARS [hazard ratio (HR) 0.94 per 1%, 95% CI 0.91, 0.97, P < 0.0001) and LV GLS (HR 1.10 per %, 95% CI 1.03, 1.17, P = 0.005) were associated with all-cause mortality, while LV ejection fraction was not. Likelihood ratio tests demonstrated that LARS provided incremental value over prognostically important clinical and imaging parameters, including late gadolinium enhancement. CONCLUSION: In patients with SSc, LARS was independently associated with the presence of NYHA class II-IV heart failure symptoms. Although both LARS and LV GLS were associated with all-cause mortality, only LARS provided incremental value over all evaluated variables known to be prognostically important in patients with SSc.

ERN ReCONNET points to consider for treating patients living with autoimmune rheumatic diseases with antiviral therapies and anti-SARS-CoV-2 antibody products.

Recent studies have shown that people who are immunocompromised may inadvertently play a role in spurring the mutations of the virus that create new variants. This is because some immunocompromised individuals remain at risk of getting COVID-19 despite vaccination, experience more severe disease, are susceptible to being chronically infected and remain contagious for longer if they become infected and considering that immunocompromised individuals represent approximately 2% of the overall population, this aspect should be carefully considered. So far, some autoimmune rheumatic disease (ARD) patients with COVID-19 have been treated with antiviral therapies or anti-SARS-CoV-2 antibody products. However, there is no homogeneous approach to these treatment strategies. This issue was addressed within the European Reference Network (ERN) on Rare and Complex Connective Tissue and Musculoskeletal Diseases (ReCONNET) in a discussion among experts and patient's representatives in the context of the rare and complex connective tissue diseases (rCTDs) covered by the Network. ERN ReCONNET is one of the 24 ERNs launched by the European Commission in 2017 with the aim of tackling low prevalence and rare diseases that require highly specialised treatment and promoting concentration of knowledge and resources through virtual networks involving healthcare providers (HCPs) across the European Union (EU). Considering the urgent need to provide guidance not only to the rCTDs community, but also to the whole ARDs community, a multidisciplinary Task Force, including expert clinicians and European Patient Advocacy Group (ePAG) Advocates, was created in the framework of ERN ReCONNET with the aim of developing overarching principles (OP) and points-to-consider (PtC) on a homogenous approach to treat immunocompromised patients with ARDs (with a particular focus on CTDs) affected by COVID-19 using antiviral therapies and anti-SARS-CoV-2 antibody products. The present work reports the final OP and PtC agreed by the Task Force.

Continued treatment with nintedanib in patients with systemic sclerosis-associated interstitial lung disease: data from SENSCIS-ON.

OBJECTIVES: In the SENSCIS trial in patients with systemic sclerosis-associated interstitial lung disease (SSc-ILD), nintedanib reduced the rate of decline in forced vital capacity (FVC) versus placebo, with adverse events that were manageable for most patients. An open-label extension trial, SENSCIS-ON, is assessing safety and FVC decline during longer term nintedanib treatment. METHODS: Patients who completed the SENSCIS trial or a drug-drug interaction (DDI) study of nintedanib and oral contraceptive on treatment were eligible to enter SENSCIS-ON. Adverse events and changes in FVC over 52 weeks of SENSCIS-ON were assessed in patients who received nintedanib in SENSCIS and continued nintedanib in SENSCIS-ON ('continued nintedanib' group) and in patients who received placebo in SENSCIS and initiated nintedanib in SENSCIS-ON or who received nintedanib for ≤28 days in the DDI study ('initiated nintedanib' group). RESULTS: There were 197 patients in the continued nintedanib group and 247 in the initiated nintedanib group. Diarrhoea was reported in 68.0% and 68.8% of patients in these groups, respectively. Adverse events led to discontinuation of nintedanib in 4.6% and 21.5% of the continued nintedanib and initiated nintedanib groups, respectively. Mean (SE) changes in FVC from baseline to week 52 of SENSCIS-ON were -58.3 (15.5) mL in the continued nintedanib group and -44.0 (16.2) mL in the initiated nintedanib group. CONCLUSIONS: The safety profile of nintedanib over 52 weeks of SENSCIS-ON was consistent with that reported in SENSCIS. The change in FVC over 52 weeks of SENSCIS-ON was similar to that observed in the nintedanib group of SENSCIS.

Biological and clinical insights from a randomized phase 2 study of an anti-oncostatin M monoclonal antibody in systemic sclerosis.

OBJECTIVES: The cytokine oncostatin M (OSM) is implicated in the pathology of SSc. Inhibiting OSM signalling using GSK2330811 (an anti-OSM monoclonal antibody) in patients with SSc has the potential to slow or stop the disease process. METHODS: This multicentre, randomized, double-blind, placebo-controlled study enrolled participants ≥18 years of age with active dcSSc. Participants were randomized 3:1 (GSK2330811:placebo) in one of two sequential cohorts to receive GSK2330811 (cohort 1: 100 mg; cohort 2: 300 mg) or placebo s.c. every other week for 12 weeks. The primary endpoint was safety; blood and skin biopsy samples were collected to explore mechanistic effects on inflammation and fibrosis. Clinical efficacy was an exploratory endpoint. RESULTS: Thirty-five participants were randomized to placebo (n = 8), GSK2330811 100 mg (n = 3) or GSK2330811 300 mg (n = 24). Proof of mechanism, measured by coordinate effects on biomarkers of inflammation or fibrosis, was not demonstrated following GSK2330811 treatment. There were no meaningful differences between GSK2330811 and placebo for any efficacy endpoints. The safety and tolerability of GSK2330811 were not favourable in the 300 mg group, with on-target, dose-dependent adverse events related to decreases in haemoglobin and platelet count that were not observed in the 100 mg or placebo groups. CONCLUSION: Despite a robust and novel experimental medicine approach and evidence of target engagement, anticipated SSc-related biologic effects of GSK2330811 were not different from placebo and safety was unfavourable, suggesting OSM inhibition may not be a useful therapeutic strategy in SSc.

Representativeness of systemic sclerosis patients in interventional randomized trials: an analysis of the EUSTAR database.

OBJECTIVE: To estimate the extent of and the reasons for ineligibility in randomized controlled trials (RCTs) of SSc patients included in the EUSTAR database, and to determine the association between patient's features and generalizability of study results. METHODS: We searched Clinicaltrials.gov for all records on interventional SSc-RCTs registered from January 2013 to January 2018. Two reviewers selected studies, and information on the main trial features were retrieved. Data from 8046 patients having a visit in the EUSTAR database since 2013 were used to check patient's eligibility. The proportion of potentially eligible patients per trial, and the risk factors for ineligibility were analysed. Complete-, worst- and best-case analyses were performed. RESULTS: Of the 37 RCTs included, 43% were conducted in Europe, 35% were industry-funded, and 87% investigated pharmacological treatments. Ninety-one percent of 8046 patients included could have participated in at least one RCT. In complete-case analysis, the median [range] proportion of eligible patients having the main organ complication targeted by each study was 60% [10-100] in the overall sample of trials, ranging from 50% [32-79] for trials on skin fibrosis to 90% [34-77] for those targeting RP. Among the criteria checked, treatment- and safety-related but not demographic were the main barriers to patient's recruitment. Older age, absence of RP, and lower mRSS were independently associated with the failure to fulfill criteria for any of the included studies. CONCLUSIONS: Patient's representativeness in SSc-RCTs is highly variable and is driven more by treatment- and safety-related rather than demographic criteria.

Evidence and consensus-based recommendations for non-pharmacological treatment of fatigue, hand function loss, Raynaud's phenomenon and digital ulcers in patients with systemic sclerosis.

OBJECTIVE: SSc is a complex CTD affecting mental and physical health. Fatigue, hand function loss, and RP are the most prevalent disease-specific symptoms of systemic sclerosis. This study aimed to develop consensus and evidence-based recommendations for non-pharmacological treatment of these symptoms. METHODS: A multidisciplinary task force was installed comprising 20 Dutch experts. After agreeing on the method for formulating the recommendations, clinically relevant questions about patient education and treatments were inventoried. During a face-to-face task force meeting, draft recommendations were generated through a systematically structured discussion, following the nominal group technique. To support the recommendations, an extensive literature search was conducted in MEDLINE and six other databases until September 2020, and 20 key systematic reviews, randomized controlled trials, and published recommendations were selected. Moreover, 13 Dutch medical specialists were consulted on non-pharmacological advice regarding RP and digital ulcers. For each recommendation, the level of evidence and the level of agreement was determined. RESULTS: Forty-one evidence and consensus-based recommendations were developed, and 34, concerning treatments and patient education of fatigue, hand function loss, and RP/digital ulcers-related problems, were approved by the task force. CONCLUSIONS: These 34 recommendations provide guidance on non-pharmacological treatment of three of the most frequently described symptoms in patients with systemic sclerosis. The proposed recommendations can guide referrals to health professionals, inform the content of non-pharmacological interventions, and can be used in the development of national and international postgraduate educational offerings.

Improvement of microangiopathy after haematopoietic stem cell transplantation in systemic sclerosis.

OBJECTIVES: Haematopoietic stem cell transplantation (HSCT) is a treatment option for patients with severe systemic sclerosis (SSc), but the efficacy of the procedure in remodelling the nailfold microvascular array is largely unknown. Therefore, this study aimed to evaluate the effect of HSCT on microangiopathy assessed through nailfold capillaroscopy (NC) and to compare the results with findings in patients receiving conventional immunosuppression. METHODS: We included SSc patients with severe SSc and whose pre- and post-treatment NC images were available. Findings in patients treated with HSCT were compared with patients not treated with HSCT. Images were scored by two independent observers blinded for clinical data and treatment history. Capillary pattern was determined and semiquantitative scores from 0 (no changes) to 3 (>66% alterations per millimetre) were used to quantify the degree of specific microvascular characteristics. Changes in severity of microangiopathy between baseline and post-treatment were compared between groups. RESULTS: Images of 18 HSCT patients and 21 controls were scored. From baseline to follow-up, 33% of HSCT patients showed improvement from scleroderma pattern to normal NC, compared to 6% of controls (p=0.15). Pre- to post-treatment differences in semiquantitative scores showed significant improvement in HSCT patients compared to controls regarding capillary loss (-0.5 vs. 0.0, p<0.05) and disorganisation (-0.8 vs. 0.0, p<0.05). CONCLUSIONS: The degree of microangiopathy improved significantly in severe SSc patients treated with HSCT compared with patients receiving conventional immunosuppressive therapy.

Feasibility of online home spirometry in systemic sclerosis-associated interstitial lung disease: a pilot study.

OBJECTIVES: Frequent monitoring of forced vital capacity at home may be of added value in patients with SSc-associated interstitial lung disease (SSc-ILD) to monitor disease progression and guide treatment decisions. The aim of this study was to evaluate the feasibility and optimal frequency of online home spirometry using a home monitoring application in patients with SSc-ILD. METHODS: This was a prospective, observational study in patients with SSc-ILD. Patients evaluated for 3 months the online home monitoring application ILD-online integrated with a Bluetooth-connected spirometer. Patients performed daily home spirometry for 6 weeks and weekly home spirometry for 6 weeks. In addition, patients completed an evaluation questionnaire after 3 months and online patient-reported outcomes at baseline and 3 months. RESULTS: Ten consecutive patients participated. Mean adherence to home spirometry was 98.8% (s.d. 1.5). Home and hospital spirometry were highly correlated. The mean coefficient of variation was lower for weekly [2.45% (s.d. 1.19)] than daily [3.86% (s.d. 1.45)] forced vital capacity measurements (P = 0.005). All patients considered the home monitoring application and spirometer easy to use and no patients considered home spirometry burdensome. All patients would recommend home monitoring to other patients with SSc. CONCLUSIONS: Home spirometry using an online home monitoring application is feasible in patients with SSc-ILD, with high adherence and patient satisfaction. Larger long-term studies are needed to assess whether home spirometry can detect the progression of ILD in patients with SSc.

Identifying unmet needs in SSc-ILD by semi-qualitative in-depth interviews.

OBJECTIVES: Interstitial lung disease is frequent in SSc (SSc-ILD) and associates with significantly reduced quality of life. Here we aimed to analyse patient pathways, and experiences of patients and healthcare providers (HCPs) in order to identify unmet needs in the management of SSc-ILD patients. METHODS: Semi-structured qualitative interviews conducted in eight European countries looked at HCP (n = 95) and patient perspectives (n = 47) using two sets of 70 research questions. Pre-diagnostic, diagnostic and post-diagnostic phases of the patient pathway were systematically explored. RESULTS: (i) In the pre-diagnostic phase several gaps were identified by HCPs and patients in all participating countries: limited disease knowledge among primary care physicians and specialists, lack of accurate patient information, and delayed and/or inappropriate referral. (ii) The diagnostic phase is in most countries coordinated by rheumatologists, who are also the main point of care. Depending on the local health system, organization of multidisciplinary collaboration varies. HCPs issued lack of national guidelines, while patients stated difficulties obtaining disease-related information. (iii) In the post-diagnostic phase, HCPs and patients indicated lack of curative treatment, specialized nurses, and paramedical  and psychological support. Patients and caregivers additionally expressed the need for clear information on SSc-ILD. CONCLUSION: Lack of disease specific knowledge, gaps in national healthcare systems and insufficient information and support for patients and caregivers were identified as unmet needs to ensure timely diagnosis, provide better patient management and to improve quality of life in SSc-ILD patients.

Pulmonary hypertension in connective tissue diseases, new evidence and challenges.

Pulmonary arterial hypertension is a lethal complication of different connective tissue diseases such as systemic sclerosis, mixed connective tissue disease and systemic lupus erythematosus. Although the treatment possibilities for patients with pulmonary arterial hypertension have increased in the last two decades and survival of patients with idiopathic pulmonary arterial hypertension has improved, the latter is not the case for patients with pulmonary arterial hypertension associated with connective tissue disease. In this narrative review, we review recent literature and describe the improvement of early diagnostic possibilities, screening modalities and treatment options. We also point out the pitfalls in diagnosis in this patient category and describe the unmet needs and what the focus of future research should be.

Opening the black box of non-pharmacological care in systemic sclerosis: a cross-sectional online survey of Dutch health professionals.

The objective is to describe the spectrum of the health professional (HP) treatment approach for systemic sclerosis (SSc) from the perspective of Dutch HPs, including alignment of treatment goals set by HPs with self-reported referral reasons, coverage of patient-reported unmet care needs, and quality of communication between HPs and rheumatologists. Dutch HPs were invited through their patients with SSc to complete an anonymous online survey. The survey covered referral reasons, treatment goals, and interventions of the last patient treated, as well as the perceived quality of communication between HPs and rheumatologists. Referral reasons and treatment targets were linked to the International Classification of Functioning, Disability and Health following the refined ICF Linking Rules. Seventy-nine HPs from 8 professions (including 58 physiotherapists, 73%) completed the survey. One hundred and thirty-three different referral reasons were reported, yielding 58 different ICF codes, with 41 (70.7%) being linked to the ICF domain "body structures and functions." The reported interventions focused on body functions/structures (27.9%), training of daily activities (25.6%), education and advice (26.3%), and psychosocial interventions (20.2%). The quality of communication between HPs and rheumatologists was perceived as low. Our findings revealed numerous treatment options offered by Dutch HPs addressing the unmet care needs of patients with SSc. There is an overlap in the content of the various HP disciplines, and HP treatment goals are not sufficiently aligned with referrals of rheumatologists. HP treatment offer seemed inefficiently organized, possibly precluding rheumatologists from making targeted referrals. Communication between rheumatologists and HPs should be improved.

Fibroblast Activation Protein Targeted Photodynamic Therapy Selectively Kills Activated Skin Fibroblasts from Systemic Sclerosis Patients and Prevents Tissue Contraction.

Systemic sclerosis (SSc) is a rare, severe, auto-immune disease characterized by inflammation, vasculopathy and fibrosis. Activated (myo)fibroblasts are crucial drivers of this fibrosis. By exploiting their expression of fibroblast activation protein (FAP) to perform targeted photodynamic therapy (tPDT), we can locoregionally deplete these pathogenic cells. In this study, we explored the use of FAP-tPDT in primary skin fibroblasts from SSc patients, both in 2D and 3D cultures. Method: The FAP targeting antibody 28H1 was conjugated with the photosensitizer IRDye700DX. Primary skin fibroblasts were obtained from lesional skin biopsies of SSc patients via spontaneous outgrowth and subsequently cultured on plastic or collagen type I. For 2D FAP-tPDT, cells were incubated in buffer with or without the antibody-photosensitizer construct, washed after 4 h and exposed to λ = 689 nm light. Cell viability was measured using CellTiter Glo®®. For 3D FAP-tPDT, cells were seeded in collagen plugs and underwent the same treatment procedure. Contraction of the plugs was followed over time to determine myofibroblast activity. Results: FAP-tPDT resulted in antibody-dose dependent cytotoxicity in primary skin fibroblasts upon light exposure. Cells not exposed to light or incubated with an irrelevant antibody-photosensitizer construct did not show this response. FAP-tPDT fully prevented contraction of collagen plugs seeded with primary SSc fibroblasts. Even incubation with a very low dose of antibody (0.4 nM) inhibited contraction in 2 out of 3 donors. Conclusions: Here we have shown, for the first time, the potential of FAP-tPDT for the treatment of fibrosis in SSc skin.

Predictive factors for treatment-related mortality and major adverse events after autologous haematopoietic stem cell transplantation for systemic sclerosis: results of a long-term follow-up multicentre study.

BACKGROUND: Autologous haematopoietic stem cell transplantation (HSCT) improves survival in systemic sclerosis (SSc) with poor prognosis, but is hampered by treatment-related mortality (TRM). OBJECTIVE: To evaluate event-free survival (EFS), TRM, response to treatment, disease progression and patient characteristics associated with events. METHODS: All patients treated with HSCT for SSc in The Netherlands until 2017 (n=92) were included. Data on skin involvement (modified Rodnan skin score (mRSS), pulmonary function (forced vital capacity (FVC) and diffusion capacity of the lungs for carbon monoxide (DLCO)), extent of interstitial lung disease on high-resolution CT using Goh scores and left ventricular ejection fraction (LVEF) were collected at baseline, 1, 2 and 5 years. Occurrence of events, defined as death or major organ failure, were collected until 2019. As control, a comparison between patients treated with cyclophosphamide (CYC) and patients with HSCT who participated in the Autologous Stem Cell Transplantation International Scleroderma (ASTIS) trial was performed. RESULTS: Median follow-up was 4.6 years. EFS estimates at 5, 10 and 15 years were 78%, 76% and 66%, respectively. Twenty deaths occurred. Mean FVC, DLCO, mRSS and Goh scores all improved significantly. Disease progression occurred in 22 patients. Frequency of TRM decreased over time and occurred more often in males. Events were independently associated with male sex, LVEF <50% and older age. In ASTIS, patients treated with HSCT (n=23) 7 events occurred versus 13 in the CYC group (n=22). CONCLUSION: Our data confirm long-term efficacy of HSCT in improving survival, skin and lung involvement in SSc. Male sex, lower LVEF and older age at baseline were identified as risk factors for events.

Treatment with cyclophosphamide i.v. pulse therapy is an option for effective treatment of skin fibrosis in patients with early systemic sclerosis.

OBJECTIVES: SSc is a autoimmune disease characterized by fibrosis of the skin and internal organs. There is a lack of evidence for the efficacy of i.v. CYC pulse therapy on skin thickening. We aimed to examine the response of i.v. CYC pulse therapy on skin thickening in our cohort of SSc patients and analysed factors that predict this response. METHODS: We retrospectively evaluated the data for 143 patients with SSc from baseline to 12, 24 and 36 months. All patients were treated with at least 6 i.v. CYC pulses (750 mg/m2/month). We applied the modified Rodnan Skin Score (mRSS) to assess skin thickening. A clinically relevant response was defined as a decrease in mRSS of 5 points and 25% from baseline. Different baseline variables for predicting response on month 12 were tested in logistic regression analyses. RESULTS: Baseline characteristics of the patients with dcSSc and lcSSc were collected. Forty-three percent (n = 42) of dcSSc patients had a clinically relevant response on month 12. Non-responding on month 6 predicts non-response on month 12 (odds ratio 37.1; 95% CI 4.5, 306.4). CONCLUSION: We concluded that i.v. CYC pulse therapy should be considered as an effective treatment option for skin thickening in dcSSc patients, because 43% of this group of patients were found to have a clinically relevant response. Of the dcSSC patients who did not respond by month 6, only 29% had a response by month 12. This finding can help the physician and patient in shared decision making about whether or not to continue therapy.

Treatment decision-making in diffuse cutaneous systemic sclerosis: a patient's perspective.

OBJECTIVES: To examine the treatment decision-making process of patients with dcSSc in the context of haematopoietic stem cell transplantation (HSCT). METHODS: A qualitative semi-structured interview study was done in patients before or after HSCT, or patients who chose another treatment than HSCT. Thematic analysis was used. Shared decision-making (SDM) was assessed with the 9-item Shared Decision Making Questionnaire (SDM-Q-9). RESULTS: Twenty-five patients [16 male/nine female, median age 47 (range 27-68) years] were interviewed: five pre-HSCT, 16 post-HSCT and four following other treatment. Whereas the SDM-Q-9 showed the decision-making process was perceived as shared [median score 81/100 (range 49-100)], we learned from the interviews that the decision was predominantly made by the rheumatologist, and patients were often steered towards a treatment option. Strong guidance of the rheumatologist was appreciated because of a lack of accessible, reliable and SSc-specific information, due to the approach of the decision-making process of the rheumatologist, the large consequence of the decision and the trust in their doctor. Expectations of outcomes and risks also differed between patients. Furthermore, more than half of patients felt they had no choice but to go for HSCT, due to rapid deterioration of health and the perception of HSCT as 'the holy grail'. CONCLUSION: This is the first study that provides insight into the decision-making process in dcSSc. This process is negatively impacted by a lack of disease-specific education about treatment options. Additionally, we recommend exploring patients' preferences and understanding of the illness to optimally guide decision-making and to provide tailor-made information.

How do patients with systemic sclerosis experience currently provided healthcare and how should we measure its quality?

OBJECTIVES: To gain insight into SSc patients' perspective on quality of care and to survey their preferred quality indicators. METHODS: An online questionnaire about healthcare setting, perceived quality of care (CQ index) and quality indicators, was sent to 2093 patients from 13 Dutch hospitals. RESULTS: Six hundred and fifty patients (mean age 59 years, 75% women, 32% limited cutaneous SSc, 20% diffuse cutaneous SSc) completed the questionnaire. Mean time to diagnosis was 4.3 years (s.d. 6.9) and was longer in women compared with men (4.8 (s.d. 7.3) vs 2.5 (s.d. 5.0) years). Treatment took place in a SSc expert centre for 58%, regional centre for 29% or in both for 39% of patients. Thirteen percent of patients was not aware of whether their hospital was specialized in SSc. The perceived quality of care was rated with a mean score of 3.2 (s.d. 0.5) (range 1.0-4.0). There were no relevant differences between expert and regional centres. The three prioritized process indicators were: good patient-physician interaction (80%), structural multidisciplinary collaboration (46%) and receiving treatment according to SSc guidelines (44%). Absence of disease progression (66%), organ involvement (33%) and digital ulcers (27%) were the three highest rated outcome indicators. CONCLUSION: The perceived quality of care evaluated in our study was fair to good. No differences between expert and regional centres were observed. Our prioritized process and outcome indicators can be added to indicators suggested by SSc experts in earlier studies and can be used to evaluate the quality of care in SSc.

Chronic Q fever associated with systemic sclerosis.

BACKGROUND: After the Q fever outbreak in the Netherlands between 2007 and 2010, more than 300 patients with chronic Q fever have been identified. Some patients were also diagnosed with systemic sclerosis, a rare immune-mediated disease. We aimed to increase awareness of concomitant chronic Q fever infection and systemic sclerosis and to give insight into the course of systemic sclerosis during persistent Q fever infection. MATERIALS AND METHODS: Chronic Q fever patients were identified after the Dutch Q fever outbreak in 2007-2010. Systemic sclerosis was diagnosed by a scleroderma expert and patients fulfilled the 2013 Classification Criteria for Systemic Sclerosis. RESULTS: Four cases presented with chronic Q fever, persistent Coxiella burnetii infection, shortly preceded or followed by the diagnosis of limited cutaneous systemic sclerosis. The three male patients of 60 years or older developed a relatively mild systemic sclerosis, which did not require immunosuppressive therapy during adequate treatment of the chronic Q fever infection. The 58-year-old female patient used immunosuppressives for her newly diagnosed systemic sclerosis at the time she likely developed a chronic Q fever infection. CONCLUSIONS: In this case series, chronic Q fever preceding systemic sclerosis was associated with a mild course of systemic sclerosis without the necessity of immunosuppressive drugs, while chronic Q fever development due to immunocompromised state was associated with a more deteriorating course of systemic sclerosis.
