Purpose: There is a lack of a valid, definition for skin ulcers in SSc to be used in clinical trials. Our aim was to develop a consensus definition for SSc-skin ulcers based on the results of a systematic literature review (SLR) for skin ulcer definitions and expert opinion; and to evaluate its face validity, reliability and feasibility. Methods: SLR for skin ulcer definitions was conducted using PubMed, Web of Science, and Cochrane library for articles published from inception to January 1st, 2016. SSc experts were to discuss the definitions’ categories and vote for the relevant terms. Reliability of the definition were tested in a second expert meeting, seven SSc experts evaluated 7 SSc pts with skin lesions twice. Face validity and feasibility evaluated by sending out case report forms(CRFs) to 4 SSc experts, they were asked to use the definition in 5 pts each. Results: A total of 3464 abstracts and titles were screened, and 446 articles were fully evaluated. Of these, 66 met eligibility criteria and skin ulcer definitions were extracted. SSc experts discussed, refined and voted on the consensus definition using nominal process. Kappa for inter-, intra-rater rater agreement was 0.51, 0.90 respectively. The mean time to decide if the lesion is an ulcer was 7.4 sec. All investigators endorsed the face validity of the new definition in the CRFs. Conclusion: Using a SLR and a nominal technique, we developed a preliminary consensus-based definition of SSc-skin ulcers. Face validity, feasibility and reliability were demonstrated for the developed definition.

Objective SB5 showed comparable efficacy and safety profile in respect to adalimumab originator (ADA) in randomized clinical trials of rheumatoid arthritis (RA) and psoriasis. We aimed to describe the efficacy and safety of SB5 after switching from ADA in RA, axial spondyloarthritis (axSpA), psoriatic arthritis (PsA) and juvenile idiopathic arthritis (JIA) patients. Method Adult RA, PsA, axSpA, JIA patients treated with ADA for at least 6 months, switched to SB5 in stable clinical conditions, were eligible. Data on safety, activity indexes and patient-reported outcomes were collected at baseline, 3 and 6 months after switching. Results Eighty-two patients (19 RA, 28 PsA, 32 axSpA and 3 JIA; 45 females, mean age 54 ± 14 years, disease duration 13 ± 7 years, ADA duration 6 ± 3 years) were enrolled. RA patients showed stable conditions, while PsA patients showed an increase in both HAQ, DAS28(CRP) and DAPSA and axSpA patients an increase in VAS pain, VAS patient disease activity and ASDAS, both at 3 months. There were changes in the concomitant medications profile, with regression of activity indexes increases at 6 months. Adverse events were reported by 33.7% patients at 3 months and 16.6% patients at 6 months, mostly disease flares and infectious events. Two patients stopped SB5. Conclusions Despite temporary changes in the concomitant medication profile for mild disease flares, our real-life data replicate the safety profile of switching from ADA to SB5 in RA, with additional data for its applicability in PsA and axSpA patients, further supporting switching to biosimilars in treating inflammatory rheumatic conditions. Key Points• Switching from adalimumab originator to SB5 is feasible in real life rheumatic inflammatory joint diseases.• Mild disease flares can present after switching from originator adalimumab to SB5, in particular in axial spondyloarthritis and psoriatic arthritis.• Changes in concomitant medications profile allows the control of minor disease flares presenting after switching from adalimumab originator to SB5.

Our data indicate that calcinosis may be classified in SSc as mousse, stone, net and plate according to its clinical and X-ray features. This classification awaits validation for a possible use in clinical practice and to support early treatment and prevention of complications.

Results of our study indicate that lower limb ulcers in SSc often have a multifactorial pathogenesis that may be difficult to manage. Further studies are needed to validate the proposed classification and to assess the most appropriate management of lower limb ulcers in SSc.

The aim of this study was to evaluate in systemic sclerosis (SSc) retrospectively the effect of Bosentan and Sildenafil and their combination on Raynaud's phenomenon (RP), function, and capillaroscopic patterns. One hundred and twenty-three SSc patients (mean age ± sd, 57.69 ± 14.07 years) were retrospectively evaluated and divided into two groups according to American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR) classification score: group 1 score < 10, group 2 score > 10. Each group was divided into three subgroups according to treatment: Bosentan, Sildenafil, and Bosentan + Sildenafil. Nailfold videocapillaroscopy (NVC), Scleroderma Health Assessment Questionnaire (SHAQ) and Raynaud Condition Score (RCS) were performed at baseline and after 3 and 6 months. In Bosentan (29 patients: 12, group 1; 17, group 2), NVC changed significantly in both groups, after 3 and 6 months (p = 0.00439, group 1; p = 0.00035, group 2). In group 1, the "active" and the "late" patterns reduced, and the "aspecific" increased. In group 2, there was a reduction of late patterns, a worsening of SHAQ (p < 0.005) and an improvement of RCS (p = 0.00014). In Sildenafil (63 patients: 35, group 1; 28, group 2), after 3 months, NVC patterns changed significantly in both groups(p = 0.042 group 1, p = 0.00089 group 2). In group 1, the late and early patterns increased, and the aspecific decreased. In group 2, a significant change of NVC pattern was observed also after 6 months (p = 0.00089): the late pattern increased while the active one reduced. After 6 months, SHAQ was significantly reduced in group 1 (p = 0.00027) and in group 2 (p = 0.0043). RCS improved in both groups (p = 0.0042, group 1; p = 0.0016, group 2). Combination therapy (Bosentan + Sildenafil) (31 patients: 14, group 1; 17, group 2) induced significant changes on NVC only in group 1 after 3 (p = 0.00256) and 6 months (p = 0.000349) with a reduction of the late and active patterns and an increase of the early pattern. In both groups, after 6 months, SHAQ (p < 0.05, group 1; p = 0.00049, group 2) and RCS significantly reduced (group 1, p = 0.00024; group 2, p = 0.0021). Patients treated with Bosentan + Sildenafil show a significant improvement of RCS and NVC. This combination therapy may exert a vascular activity achieving an amelioration of the structure of microvasculature in SSc.
