Rheumatic diseases in migrant patients resident in Tuscany: epidemiological data analysis and single-center experience.

OBJECTIVE: In the last decades, the number of foreigners in Tuscany has considerably increased with a multiethnic distribution. We reviewed the main rheumatic diseases in the foreign population resident in Tuscany and also reported the experience at the Rheumatology Division of the University Hospital of Careggi, Florence, in order to identify the areas of origin of these patients and the main rheumatic diseases observed in them. METHODS: The collaboration with the Tuscan Region provided data about foreign patients residing in Tuscany on January 1, 2021 (country of origin, chronic diseases). Moreover, we conducted a retrospective review of the clinical charts of our Rheumatologic Division from January 1, 2019, to December 31, 2020. RESULTS: In Tuscany, on January 1, 2021, there were 61,373 patients with chronic inflammatory rheumatic diseases, and 3994 of them (6.51%) were foreigners. Most patients were born in Europe (39.03%), followed by the Balkans (15%), South America (11.27%), and North Africa (10.31%). Inflammatory joint diseases, Sjögren syndrome, and systemic lupus erythematosus were the most frequent diseases. In the period 2019-2020, 511 foreign patients visited our Rheumatology Division and mainly originated from the Balkans (34.64%), South America (18%), and European countries (16.44%). In these patients, chronic inflammatory joint diseases and connective tissue diseases (systemic sclerosis, Sjögren syndrome, and systemic lupus erythematosus) were the most prevalent diseases. CONCLUSIONS: This study provides a picture of the rheumatic diseases affecting foreign patients residing in Tuscany that are in agreement with the epidemiological data previously provided.

Use of vasoactive/vasodilating drugs for systemic sclerosis (SSc)-related digital ulcers (DUs) in expert tertiary centres: results from the analysis of the observational real-life DeSScipher study.

INTRODUCTION: DeSScipher is the first European multicentre study on management of systemic sclerosis (SSc), and its observational trial 1 (OT1) evaluated the efficacy of different drugs for digital ulcer (DU) prevention and healing. The aim of this study was to assess current use of vasoactive/vasodilating agents for SSc-related DU in the expert centres by analysing the baseline data of the DeSScipher OT1. METHOD: Baseline characteristics of patients enrolled in the OT1 and data regarding DU were analysed. RESULTS: The most commonly used drugs, in both patients with and without DU, were calcium channel blockers (CCBs) (71.6%), followed by intravenous iloprost (20.8%), endothelin receptor antagonists (ERAs) (20.4%) and phosphodiesterase 5 (PDE-5) inhibitors (16.5%). Of patients, 32.6% with DU and 12.8% without DU received two drugs (p < 0.001), while 11.5% with DU and 1.9% without DU were treated with a combination of three or more agents (p < 0.001). Sixty-five percent of the patients with recurrent DU were treated with bosentan and/or sildenafil. However, 64 out of 277 patients with current DU (23.1%) and 101 (23.6%) patients with recurrent DU were on CCBs alone. CONCLUSIONS: Our study shows that CCBs are still the most commonly used agents for DU management in SSc. The proportion of patients on combination therapy was low, even in patients with recurrent DU: almost one out of four patients with current and recurrent DU was on CCBs alone. Prospective analysis is planned to investigate the efficacy of different drugs/drug combinations on DU healing and prevention. Key Points • The analysis of DeSScipher, the first European multicentre study on management of SSc, has shown that the most commonly used vasoactive/vasodilating drugs for DU were CCBs, followed by intravenous Iloprost, ERAs and PDE-5 inhibitors. • More than half of the patients with recurrent DU received bosentan and/or sildenafil. • However, the proportion of patients on combination therapy of more than one vasoactive/vasodilating drug was low and almost one out of four patients with current and recurrent DU was on CCBs alone.

Classification, categorization and essential items for digital ulcer evaluation in systemic sclerosis: a DeSScipher/European Scleroderma Trials and Research group (EUSTAR) survey.

BACKGROUND: A consensus on digital ulcer (DU) definition in systemic sclerosis (SSc) has been recently reached (Suliman et al., J Scleroderma Relat Disord 2:115-20, 2017), while for their evaluation, classification and categorisation, it is still missing. The aims of this study were to identify a set of essential items for digital ulcer (DU) evaluation, to assess if the existing DU classification was useful and feasible in clinical practice and to investigate if the new categorisation was preferred to the simple distinction of DU in recurrent and not recurrent, in patients with systemic sclerosis (SSc). METHODS: DeSScipher is the largest European multicentre study on SSc. It consists of five observational trials (OTs), and one of them, OT1, is focused on DU management. The DeSScipher OT1 items on DU that reached ≥ 60% of completion rate were administered to EUSTAR (European Scleroderma Trials and Research group) centres via online survey. Questions about feasibility and usefulness of the existing DU classification (DU due to digital pitting scars, to loss of tissue, derived from calcinosis and gangrene) and newly proposed categorisation (episodic, recurrent and chronic) were also asked. RESULTS: A total of 84/148 (56.8%) EUSTAR centres completed the questionnaire. DeSScipher items scored by ≥ 70% of the participants as essential and feasible for DU evaluation were the number of DU defined as a loss of tissue (level of agreement 92%), recurrent DU (84%) and number of new DU (74%). For 65% of the centres, the proposed classification of DU was considered useful and feasible in clinical practice. Moreover, 80% of the centres preferred the categorisation of DU in episodic, recurrent and chronic to simple distinction in recurrent/not recurrent DU. CONCLUSIONS: For clinical practice, EUSTAR centres identified only three essential items for DU evaluation and considered the proposed classification and categorisation as useful and feasible. The set of items needs to be validated while further implementation of DU classification and categorisation is warranted. TRIAL REGISTRATION: Observational trial on DU (OT1) is one of the five trials of the DeSScipher project (ClinicalTrials.gov; OT1 Identifier: NCT01836263 , posted on April 19, 2013).

Defining Skin Ulcers in Systemic Sclerosis: Systematic Literature Review and Proposed World Scleroderma Foundation (WSF) definition.

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.

Combination therapy with Bosentan and Sildenafil improves Raynaud's phenomenon and fosters the recovery of microvascular involvement in systemic sclerosis.

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.
