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.)

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.
