Objective To describe demographic, clinical and laboratory features of systemic sclerosis sine scleroderma (ssSSc) in a large multicentre systemic sclerosis (SSc) cohort.Methods Data involving 1808 SSc patients from Italian Systemic sclerosis PRogression INvestiGation registry were collected. The ssSSc was defined by the absence of any cutaneous sclerosis and/or puffy fingers. Clinical and serological features of ssSSc were compared with limited cutaneous (lcSSc) and diffuse cutaneous (dcSSc) subsets.Results Among patients with SSc, only 61 (3.4%) were classified as having ssSSc (F/M=19/1). Time from Raynaud’s phenomenon (RP) onset to diagnosis was longer in ssSSc (3 years, IQR 1–16.5) than lcSSc (2 years, IQR 0–7), and dcSSc (1 year, IQR 0–3) (p

Objectives: To evaluate the performance of oropharyngoesophageal scintigraphy (OPES) in the assessment of dysphagia in patients with systemic sclerosis (SSc), and to compare OPES results with those of barium esophagogram. Methods: Adult SSc patients who underwent OPES for the assessment of dysphagia were enrolled. OPES was performed with both liquid and semisolid boluses and provided information regarding oropharyngeal transit time, esophageal transit time (ETT), oropharyngeal retention index (OPRI), esophageal retention index (ERI), and site of bolus retention. Barium esophagogram results were also collected. Results: Fifty-seven SSc patients (87.7% female, mean age 57.7 years) with dysphagia were enrolled. OPES identified at least one alteration in each patient and findings were generally worse for the semisolid bolus. Esophageal motility was widely impaired with 89.5% of patients with an increased semisolid ERI, and middle-lower esophagus was the most frequent site of bolus retention. However, oropharyngeal impairment was highlighted by widespread increased OPRI, especially in anti-topoisomerase I positivity. Older patients and with longer disease duration presented slower semisolid ETT (p = 0.029 and p = 0.002, respectively). Eleven patients with dysphagia had a negative barium esophagogram: all of them presented some alterations in OPES parameters. Conclusion: OPES revealed a marked SSc esophageal impairment, in terms of both slowed transit time and increased bolus retention, but also shed light on oropharyngeal swallowing alterations. OPES showed high sensitivity, being able to detect swallowing alterations in dysphagic patients with negative barium esophagogram. Therefore, the use of OPES for the assessment of SSc-related dysphagia in clinical practice should be promoted. [ABSTRACT FROM AUTHOR]

Background: To assess skin involvement in a cohort of patients with systemic sclerosis (SSc) by comparing results obtained from modified Rodnan skin score (mRSS), durometry and ultra-high frequency ultrasound (UHFUS). Methods: SSc patients were enrolled along with healthy controls (HC), assessing disease-specific characteristics. Five regions of interest were investigated in the non-dominant upper limb. Each patient underwent a rheumatological evaluation of the mRSS, dermatological measurement with a durometer, and radiological UHFUS assessment with a 70 MHz probe calculating the mean grayscale value (MGV). Results: Forty-seven SSc patients (87.2% female, mean age 56.4 years) and 15 HC comparable for age and sex were enrolled. Durometry showed a positive correlation with mRSS in most regions of interest (p = 0.025, ρ = 0.34 in mean). When performing UHFUS, SSc patients had a significantly thicker epidermal layer (p < 0.001) and lower epidermal MGV (p = 0.01) than HC in almost all the different regions of interest. Lower values of dermal MGV were found at the distal and intermediate phalanx (p < 0.01). No relationships were found between UHFUS results either with mRSS or durometry. Conclusions: UHFUS is an emergent tool for skin assessment in SSc, showing significant alterations concerning skin thickness and echogenicity when compared with HC. The lack of correlations between UHFUS and both mRSS and durometry suggests that these are not equivalent techniques but may represent complementary methods for a full non-invasive skin evaluation in SSc.

Digital ulcers (DUs) represent one of the major burdens for patients with systemic sclerosis (SSc), especially when associated with skin calcinosis (SC). The aim of this work is to evaluate the impact of SC in DUs of patients with SSc for clinical characteristics and prognosis assessed by the wound bed score (WBS). We prospectively enrolled 55 patients with DUs and SSc followed in our dedicated wound care clinic. For all the patients we collected clinical and anthropometric data and characteristics of the DU, and we calculated the WBS for each DU. Ninety‐nine DUs were evaluated (24 with SC). SC was prevalent in limited cutaneous SSc (75%) and in patients with longer disease duration (P = 0.02). SC‐DUs were prevalent at the fingertip (P = 0.04). The healing time was significantly higher in patients with SC (10.4 ± 7.9 weeks) compared with non‐SC (7.0 ± 5.7 weeks) P = 0.03. The WBS negatively correlated with the time to achieve complete healing (r = −0.237 P = 0.023) and the correlation was maintained in the non‐SC (r = −0.46, P = 0.033). DUs in SSc patients with SC are common and difficult to heal. When DUs are treated in dedicated centres, the prognosis is good. The WBS is fast and easy and maybe commonly applied in clinical practice. [ABSTRACT FROM AUTHOR]

To provide a full characterization of proper palmar digital arteries (PPDA) in systemic sclerosis (SSc) with ultra-high frequency ultrasound (UHFUS), and to investigate possible relationships between digital macroangiopathy and microangiopathy. SSc patients without active digital ulcers and healthy controls (HC) were enrolled. Each subject underwent UHFUS 70 MHz evaluation of PPDA from II to V fingers bilaterally, searching for vessel occlusion and measuring the thickness of the three arterial layers and the systolic-diastolic excursion range. Microcirculation was investigated with capillaroscopy and laser speckle contrast analysis (LASCA). Forty-six SSc patients (87% female, mean age 55.5 years) and 15 HC comparable for age and sex were enrolled. UHFUS in SSc revealed the occlusion of 124 (16.8%) PPDA, whereas in HC they were all patent. Considering a finger with at least one PPDA occluded as ultrasonographically pathological, 67.4% patients presented ≥1 pathological fingers. All three arterial layers were significantly thicker and excursion range significantly reduced in SSc than in HC (p<0.001 for all). Seventy-three percent of fingers previously affected by digital ulcers, were ultrasonographically pathological. Disease duration was directly correlated to the thickness of all three arterial layers. No significant correlations emerged between capillaroscopy or LASCA findings and UHFUS features. UHFUS allows the characterization of vasculopathic involvement of PPDA in SSc, also showing subclinical vasculopathy. The lack of correlations between UHFUS and capillaroscopy or LASCA likely mirrors non-overlapping vasculopathic processes. UHFUS evaluation of PPDA emerges as complementary to microcirculation assessment for a more accurate and complete characterization of SSc vasculopathy. [ABSTRACT FROM AUTHOR]

Joint involvement is a common manifestation of systemic lupus erythematosus (SLE) and is described as a non-erosive mild synovitis. However some SLE patients may present a more severe joint involvement requiring aggressive therapy. We describe the case of a SLE patient with a severe arthritis unresponsive to methotrexate, successfully treated with anti-TNF-alpha drug as induction therapy and we report the results of a systematic literature review on the use of TNF-alpha inhibitors in SLE.

Mixed cryoglobulinemia remains a major challenge to the clinician, both in terms of diagnosis and treatment. The discovery of its association with the hepatitis C virus has helped to shed light on the mechanisms of its pathogenesis and on how this complex disease might be managed. In this respect, interferon represents the first attempt to take an etiological approach to the treatment of a virus-related, immune-mediated human disease. Its uneven results, however, have on the one hand raised hopes that a final solution to the problem may be near, and at the same time underlined the fact that we probably have a long way to go before our goal is actually reached.

Objectives: Lung ultrasound (LUS) and high-resolution CT (HRCT) are commonly used for the evaluation of interstitial lung disease (ILD). Nintedanib (NIN) is an antifibrotic therapy approved for systemic sclerosis-associated ILD (SSc-ILD). We assessed LUS and quantitative HRCT changes in SSc-ILD patients treated with NIN during a 1 year follow-up, evaluating relationships between imaging variations and functional or quality-of-life outcomes., Methods: SSc-ILD patients who started NIN were enrolled and followed for 12 months. Pulmonary function tests and patient-reported outcome measures (PROMs) were assessed half-yearly and quarterly, respectively. LUS was performed quarterly evaluating the presence of B-lines (BL) and pleural line irregularities (PLI). HRCT was repeated after 1 year and quantitatively analysed with CALIPER software., Results: Ten patients (70% female, mean age 62 years) were enrolled. The mean total number of both BL and PLI was constantly decreased during NIN treatment, being significantly reduced after 12 months (from 175.1 [66.7] to 120.8 [70.3] for BL, P = 0.005; and from 50.6 [32.5] to 37.2 [22.4] for PLI, P = 0.05). Male gender, smoking habit and baseline forced vital capacity <70% predicted were associated with worse LUS outcomes. A greater reduction in both BL and PLI was observed in those who improved in PROMs, especially modified Medical Research Council dyspnoea scale (P = 0.016 and P = 0.04, respectively) and Saint George's Respiratory Questionnaire (P = 0.006 and P = 0.026, respectively). No significant changes in the CALIPER percentages of normal parenchyma or ILD elements were observed after 12 months of NIN, thus paralleling the stabilization obtained at pulmonary function tests., Conclusion: We present preliminary results on NIN effects on SSc-ILD as assessed by LUS, a useful method for frequently repeated monitoring, and CALIPER, a valid implementation whenever a HRCT is performed., (© The Author(s) 2023.

Objective: To optimise the organisation of care and encourage the adoption of good clinical practices, the RarERN Path © methodology was designed within ERN ReCONNET. The aim of our work was to report the application of RarERN Path © on systemic sclerosis within the ERN ReCONNET centres, providing a feasible and flexible organisational reference model for optimising the systemic sclerosis care pathway in different countries., Methods: RarERN Path © is a six-phase methodology which enables the creation of a reference organisational model co-designed on the basis of the expertise of different stakeholders. It foresees six phases, ranging from the map of existing patients' care pathways and patients' stories, to the consensus on a common organisational patient care pathways, and its key performance indicators definition., Results: The agreed reference model highlights the importance of having an organisational flow for referrals that foresees how patients may access directly the specialised unit from the different referrals. Specific specialised visits were considered as mandatory to be organised and they included cardiologist, pneumologist, gastroenterologist, psychologist, nephrologist, dermatologist, wound care specialist/nurses and other healthcare professionals (such as nurses, social workers and nutritional counselling). Moreover, specific services related to therapy were highlighted as strongly recommended to be organised, mainly represented by infusion therapy and wound care, as well as occupation therapy and physiotherapy., Conclusion: The organisational model emerged from our investigation emphasises that the organisation of specific services for systemic sclerosis treatment should be organised as a solid support for implementing the existing recommendations on systemic sclerosis management in real life., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship and/or publication of this article., (© The Author(s) 2024.)

Objective: Raynaud phenomenon (RP) and digital ulcers (DUs) are the main signs of digital vasculopathy in systemic sclerosis (SSc). Selexipag is an oral prostacyclin agonist approved for SSc-related pulmonary arterial hypertension. Following our previous preliminary short-course report, we herein present long-term data on selexipag safety and efficacy in the treatment of SSc digital vasculopathy., Methods: Selexipag was administered to patients with SSc with severe digital vasculopathy refractory or with contraindication to all other vasoactive therapies. Each subject was assessed at baseline and after 3, 6, and 12 months. Clinical outcomes related to RP and DUs were evaluated along with modified Rodnan skin score of the fingers. Digital perfusion was assessed by laser speckle contrast analysis (LASCA). Nailfold videocapillaroscopy (NVC) was also performed., Results: Eight patients with SSc (63% female, mean age 50.1 years) received selexipag. After 12 months of treatment, RP was reported to significantly decrease in the number of daily episodes and mean duration ( P < 0.001 and P = 0.01, respectively). All patients achieved a complete healing of their DUs ( P = 0.03) within 6 months. A progressive reduction of fingers skin score was observed ( P = 0.03). No structural changes of capillaries were noted on NVC. Conversely, LASCA revealed an important increase in total digital perfusion ( P = 0.004) despite seasonal variability. The safety profile was consistent with that reported in the literature., Conclusion: We observed a sustained efficacy of selexipag on SSc digital vasculopathy during 1 year of administration. Our promising results encourage the design of a new randomized controlled trial to evaluate the effect of selexipag on SSc digital vasculopathy., (Copyright © 2024 by the Journal of Rheumatology.)

Systemic sclerosis (SSc) is a rare and chronic connective tissue disease of unknown aetiology and characterised by three main pathogenetic events represented by endothelial damage, inflammation with activation of the immune system leading to production of specific autoantibodies and finally fibrosis. SSc is a heterogeneous disease and the classification in two subsets, the limited cutaneous (lcSSc) subset and the diffuse cutaneous one (dcSSc), is not capable of capturing the broad and different phenotypic expression of the disease. In the last years progress has been made in the knowledge of SSc pathogenesis, in its early diagnosis and new therapeutic strategies have been proposed, however, the management of SSc still represents a challenge for the clinician. For this reason, every year several studies investigate new insights of disease pathogenesis, internal organ involvement and therapeutic approaches. The purpose of this review is to provide an overview of the literature published in 2023.

Background: Intravenous iloprost has been widely used for the treatment of systemic sclerosis peripheral vasculopathy. No agreement has been found on the regimen and the dosage of intravenous iloprost in different scleroderma subset conditions. This study aimed to evaluate the modalities of intravenous iloprost administration within a large cohort of systemic sclerosis patients from the SPRING Registry and to identify any associated clinical-demographic, instrumental or therapeutic data., Patients and Methods: Data of systemic sclerosis patients treated with intravenous iloprost for at least 1 year (case group) were retrospectively analyzed, including different timing and duration of intravenous iloprost session, and compared with those of untreated patients (control group)., Results: Out of 1895 analyzed patients, 937 (49%) received intravenous iloprost treatment, while 958 (51%) were assigned to the control group. Among cases, about 70% were treated every 4 weeks, 24% with an interval of more than 4 weeks, and only 6% of less than 4 weeks. Most patients receiving the treatment every 4 weeks, or less, underwent infusion cycle for 1 day only, while if it was scheduled with an interval of more than 4 weeks, a total number of 5 consecutive days of infusions was the preferred regimen. The comparison between the two groups revealed that patients treated with intravenous iloprost had a higher frequency of DUs (p < 0.001), pitting scars (p < 0.001), diffuse cutaneous involvement (p < 0.001), interstitial lung disease (p < 0.002), as well as higher rates of anti-topoisomerase I, " late " scleroderma pattern at nailfold videocapillaroscopy. These findings were confirmed by multivariate analysis., Conclusion: Our data provide a picture on the Italian use of intravenous iloprost among systemic sclerosis patients and showed that it was usually employed in patients with a more aggressive spectrum of the disease. The disparity of intravenous iloprost treatment strategies in the different centers suggests the need of a rational therapeutical approach based on the clinical characteristics of different patients' subsets., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2024.)

Systemic sclerosis is a rare and chronic connective tissue disease resulting from an intricate pathogenesis and is expressed in very heterogeneous clinical manifestations. Every year many studies try to unravel and shed new insight into the pathogenesis, organ involvement and treatment of this complex and severe disease. We herein provide an overview of the most relevant studies published in the literature in 2022.

Objective: Systemic sclerosis (SSc) is burdened by Raynaud phenomenon (RP) and digital ulcers (DUs), and sometimes standard vasoactive therapies are ineffective or contraindicated. Selexipag is an oral selective IP prostacyclin receptor agonist approved for the treatment of SSc-related pulmonary arterial hypertension. We aimed to evaluate the clinical and instrumental efficacy of selexipag in SSc digital vasculopathy., Methods: Patients with SSc with severe digital vasculopathy refractory or with contraindication to all other vasoactive therapies were administered selexipag. RP- and DU-related clinical outcomes were evaluated, and digital perfusion was assessed by laser speckle contrast analysis (LASCA), all at baseline and after 3 months., Results: Selexipag was administered to 9 patients with SSc (66.6% female, mean age 52.3 [SD 16.6] yrs). One patient had to stop the drug because of adverse effects. After 3 months of selexipag administration, there was a significant reduction in RP daily episodes ( P = 0.01) and RP mean duration ( P = 0.04). The number of DUs decreased from 10 to 4 without reaching statistical significance. A significant improvement in mean perfusion of the fingers ( P = 0.02) was observed with LASCA., Conclusion: Selexipag showed good potential for the treatment of SSc digital vasculopathy. Our results are certainly preliminary, yet quite encouraging. New trials for the evaluation of selexipag efficacy in SSc digital vasculopathy are needed., (Copyright © 2023 by the Journal of Rheumatology.)

Objective: To describe demographic, clinical and laboratory features of systemic sclerosis sine scleroderma (ssSSc) in a large multicentre systemic sclerosis (SSc) cohort., Methods: Data involving 1808 SSc patients from Italian Systemic sclerosis PRogression INvestiGation registry were collected. The ssSSc was defined by the absence of any cutaneous sclerosis and/or puffy fingers. Clinical and serological features of ssSSc were compared with limited cutaneous (lcSSc) and diffuse cutaneous (dcSSc) subsets., Results: Among patients with SSc, only 61 (3.4%) were classified as having ssSSc (F/M=19/1). Time from Raynaud's phenomenon (RP) onset to diagnosis was longer in ssSSc (3 years, IQR 1-16.5) than lcSSc (2 years, IQR 0-7), and dcSSc (1 year, IQR 0-3) (p<0.001). Clinical ssSSc phenotype was comparable to lcSSc, except for digital pitting scars (DPS) (19.7% vs 42%, p=0.01), but significantly milder than dcSSc, particularly for digital ulcers (DU) (6.6% vs 35.7%, p<0.001), oesophagus (46.2% vs 63.5%, p=0.009), lung (mean diffusion capacity for carbon monoxide 72.2±19.6 vs 62.4±22.8, p=0.009; mean forced vital capacity 105.6±21.7 vs 89.2±20.9, p<0.001) and major videocapillaroscopic alterations (late pattern 8.6% vs 47.6%, p<0.001). Moreover, in ssSSc the percentages of anticentromere and antitopoisomerase were comparable to lcSSc (40% and 18.3% vs 36.7% and 26.6%), but divergent respect to dcSSc (8.6% and 67.4%, p<0.001)., Conclusion: The ssSSc is a quite rare disease variant characterised by clinico-serological features comparable to lcSSc, but significantly different from dcSSc. Overall, longer RP duration, low percentages of DPS and peripheral microvascular abnormalities, and increased anti-centromere seropositivity distinguish ssSSc. Further investigations based on national registries might provide useful insights on the actual relevance of the ssSSc within the scleroderma spectrum., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Systemic sclerosis (SSc) is an autoimmune disease characterised by microvasculopathy, immune dysregulation, and skin and visceral organ fibrosis. Every year novel insights into the pathogenesis, organ involvement and treatment of this severe disease are published in the scientific community.In this review we report an overview of some of the most relevant contributions published in 2021.

Objectives: To compare two algorithms for cardiovascular (CV) risk estimation in systemic sclerosis (SSc) patients, investigating correlations with disease characteristics., Methods: Traditional CV risk factors and SSc-specific characteristics were assessed in a cohort of SSc patients. Framingham and QRISK3 algorithms were used to estimate the risk of developing a CV disease over the next 10 years., Results: Seventy-two SSc patients were enrolled. Among those 56 without previous CV events, Framingham reported a median risk score of 9.6%, classifying 24 (42.9%) subjects at high risk. QRISK3 showed a median risk score of 15.8%, with 36 (64.3%) patients considered at high risk. Both algorithms revealed a significant role of some traditional risk factors and a noteworthy potential protective role of endothelin receptor antagonists (p = .003). QRISK3 was also significantly influenced by some SSc-specific characteristics, such as limited cutaneous subset (p = .01), interstitial lung disease (p = .04), and non-ischemic heart involvement (p = .03), with the first two maintaining statistical significance in the multivariate analysis (p = .02)., Conclusions: QRISK3 classifies more SSc patients at high risk to develop CV diseases than Framingham, reflecting the influence of some SSc-specific characteristics. If its predictive accuracy were prospectively verified, the use of QRISK3 as a tool in the early detection of SSc patients at high CV risk should be recommended., (© Japan College of Rheumatology 2021.

Objective: There is still a great deal to learn about the influence of sex in systemic sclerosis (SSc). In this respect, national registries provide large and homogeneous patient cohorts for analytical studies. We therefore investigated a wide-ranging and well-characterized SSc series with the aim of identifying sex differences in disease expression, with a special focus on demographic, clinical, and serological characteristics., Methods: A multicenter SSc cohort of 2281 patients, including 247 men, was recruited in the Italian Systemic sclerosis PRogression INvestiGation (SPRING) registry. Demographic data, disease manifestations, serological profile, and internal organ involvement were compared., Results: The overall female/male ratio was 8.2:1. Female/male ratios for limited cutaneous SSc, diffuse cutaneous SSc, and SSc sine scleroderma subsets were 8.7:1, 4.9:1, and 10.7:1, respectively. A shorter time from onset of Raynaud phenomenon to SSc diagnosis, an increased prevalence of the diffuse cutaneous subset, renal crisis, and digital ulcers were found in males, whereas a significantly higher percentage of sicca syndrome, serum antinuclear antibodies, antiextractable nuclear antigens, anti-La/SSB, and anticentromere protein B was detected in the female group. Males exhibited lower left ventricular ejection fraction, as well as higher prevalence of conduction blocks, arrhythmias, ground glass, and honeycombing. Moreover, forced vital capacity and total lung capacity were medially lower in men than in women. Finally, males were more frequently treated with immunosuppressive drugs., Conclusion: Our study further supports the presence of several sex-related differences in patients with SSc. These differences were pronounced in the severity of cutaneous, peripheral vascular, and cardiopulmonary involvement for male patients, whereas an increased prevalence of sicca syndrome and a specific autoantibody profile characterized the female sex., (© 2022 by the Journal of Rheumatology.)

Systemic sclerosis is a rare and chronic connective tissue disease with a multifaceted pathogenesis characterised by heterogeneous multi-organ clinical manifestations. Every year, many studies contribute to enrich the knowledge on the pathogenesis, organ involvement and treatment of this complex and severe disease. We herein provide an overview on the most relevant contributions published in the literature in 2020.

Objectives: Systemic sclerosis (SSc) is a severe multiple-organ disease characterised by unpredictable clinical course, inadequate response to treatment, and poor prognosis. National SSc registries may provide large and representative patients cohorts required for descriptive and prognostic studies. Therefore, the Italian Society for Rheumatology promoted the registry SPRING (Systemic sclerosis Progression INvestiGation)., Methods: The SPRING is a multi-centre rheumatological cohort study encompassing the wide scleroderma spectrum, namely the primary Raynaud's phenomenon (pRP), suspected secondary RP, Very Early Diagnosis of Systemic Sclerosis (VEDOSS), and definite SSc. Here we describe the demographic and clinical characteristics of a population of 2,028 Italian patients at the initial phase of enrolment, mainly focusing on the cohort of 1,538 patients with definite SSc., Results: Definite SSc showed a significantly higher prevalence of digital ulcers, capillaroscopic 'late' pattern, oesophageal and cardio-pulmonary involvement compared to VEDOSS, as expected on the basis of the followed classification criteria. The in-depth analysis of definite SSc revealed that male gender, diffuse cutaneous subset, and anti-Scl70 seropositivity were significantly associated with increased prevalence of the most harmful disease manifestations. Similarly, patients with very short RP duration (≤1 year) at SSc diagnosis showed a statistically increased prevalence of unfavourable clinico-serological features., Conclusions: Nationwide registries with suitable subsetting of patients and follow-up studies since the prodromal phase of the disease may give us valuable insights into the SSc natural history and main prognostic factors.

Systemic sclerosis (SSc) is a connective tissue disease characterised by diffuse microangiopathy and immune dysregulation which ultimately results in widespread fibrosis of the skin and internal organs. This complex autoimmune disease is characterised by heterogeneous clinical manifestations and variable disease course in which the severity of pathology dictates the disease prognosis and course. Every year novel insights into the pathogenesis, organ involvement and treatment of this severe disease are published. Herewith, we provide an overview of the most significant literature contributions published last year, with the aim of helping the clinician in the understanding and management of SSc patients.

Systemic sclerosis (SSc) is a complex disorder characterised by the involvement of small arteries, microvessels and connective tissue, with deposition of fibrotic tissue and microvascular obliteration in the skin and internal organs. Due to the multifaceted nature of the disease, several articles are published in the medical literature every year, aimed at exploring different aspects of the pathogenesis, internal organ involvement and clinical aspects, and possible therapeutic approaches. In this article we have reviewed the literature on SSc of the past year, with the aim of identifying novel approaches that may help the treating physician in the clinical management of patients.

Systemic sclerosis (SSc) is an orphan disease characterised by autoimmunity, fibrosis of the skin and internal organs, and vasculopathy. SSc may be associated with high morbidity and mortality. In this narrative review we summarise the results of a systematic literature research, which was performed as part of the European Reference Network on Rare and Complex Connective Tissue and Musculoskeletal Diseases project, aimed at evaluating existing clinical practice guidelines or recommendations. Only in the domains 'Vascular & Ulcers' (ie, non-pharmacological approach to digital ulcer), 'PAH' (ie, screening and treatment), 'Treatment' and 'Juveniles' (ie, evaluation of juveniles with Raynaud's phenomenon) evidence-based and consensus-based guidelines could be included. Hence there is a preponderance of unmet needs in SSc referring to the diagnosis and (non-)pharmacological treatment of several SSc-specific complications. Patients with SSc experience significant uncertainty concerning SSc-related taxonomy, management (both pharmacological and non-pharmacological) and education. Day-to-day impact of the disease (loss of self-esteem, fatigue, sexual dysfunction, and occupational, nutritional and relational problems) is underestimated and needs evaluation., Competing Interests: Conflicts of interest: VS, None to declare.
