INTRODUCTION: Heart involvement is a common problem in systemic sclerosis. Recently, a definition of systemic sclerosis primary heart involvement had been proposed. Our aim was to establish consensus guidance on the screening, diagnosis and follow-up of systemic sclerosis primary heart involvement patients. METHODS: A systematic literature review was performed to investigate the tests used to evaluate heart involvement in systemic sclerosis. The extracted data were categorized into relevant domains (conventional radiology, electrocardiography, echocardiography, cardiac magnetic resonance imaging, laboratory, and others) and presented to experts and one patient research partner, who discussed the data and added their opinion. This led to the formulation of overarching principles and guidance statements, then reviewed and voted on for agreement. Consensus was attained when the mean agreement was ⩾7/10 and of ⩾70% of voters. RESULTS: Among 2650 publications, 168 met eligibility criteria; the data extracted were discussed over three meetings. Seven overarching principles and 10 guidance points were created, revised and voted on. The consensus highlighted the importance of patient counseling, differential diagnosis and multidisciplinary team management, as well as defining screening and diagnostic approaches. The initial core evaluation should integrate history, physical examination, rest electrocardiography, trans-thoracic echocardiography and standard serum cardiac biomarkers. Further investigations should be individually tailored and decided through a multidisciplinary management. The overall mean agreement was 9.1/10, with mean 93% of experts voting above 7/10. CONCLUSION: This consensus-based guidance on screening, diagnosis and follow-up of systemic sclerosis primary heart involvement provides a foundation for standard of care and future feasibility studies that are ongoing to support its application in clinical practice.

OBJECTIVE: To investigate outcomes following the tapering or discontinuation of tocilizumab in patients with diffuse cutaneous SSc (dcSSc) in a real-world setting. METHODS: Fifteen patients who were treated with tocilizumab for dcSSc were selected from a single-centre cohort database and were evaluated for serial changes in the modified Rodnan total skin thickness score (mRSS) and predicted forced vital capacity (FVC) and the occurrence of clinical worsening events after the introduction of tocilizumab. RESULTS: Over 12 months of treatment with tocilizumab, the mRSS decreased from 20.4 ± 10.7 to 12.3 ± 8.5 (P = 0.003) and FVC increased from 84.3 ± 13.7% to 88.5 ± 16.4% (P = 0.04). Tocilizumab was tapered or discontinued in seven and three patients, respectively, after improvement in skin thickening without occurrence or progression of organ manifestations. One (14%) of seven patients who underwent tocilizumab tapering experienced a worsening of skin thickening, while all three patients who discontinued tocilizumab experienced a worsening of skin thickening and/or new development of pericarditis, arthritis, interstitial lung disease or pulmonary arterial hypertension. The additional patient who discontinued tocilizumab due to an adverse event experienced subsequent progression of multiple organ manifestations, including skin, lung, lower gastrointestinal and renal involvement, leading to mortality. CONCLUSION: Our findings suggest potential benefits of prolonged tocilizumab use in dcSSc patients. The discontinuation of tocilizumab can lead to the progression of skin and visceral manifestations. Tapering rather than the discontinuation of tocilizumab is a viable option in dcSSc patients who experience remarkable clinical improvement.

INTRODUCTION: Primary heart involvement in systemic sclerosis may cause morpho-functional and electrical cardiac abnormalities and is a common cause of death. The absence of a clear definition of primary heart involvement in systemic sclerosis limits our understanding and ability to focus on clinical research. We aimed to create an expert consensus definition for primary heart involvement in systemic sclerosis. METHODS: A systematic literature review of cardiac involvement and manifestations in systemic sclerosis was conducted to inform an international and multi-disciplinary task force. In addition, the nominal group technique was used to derive a definition that was then subject to voting. A total of 16 clinical cases were evaluated to test face validity, feasibility, reliability and criterion validity of the newly created definition. RESULTS: In total, 171 publications met eligibility criteria. Using the nominal group technique, experts added their opinion, provided statements to consider and ranked them to create the consensus definition, which received 100% agreement on face validity. A median 60(5-300) seconds was taken for the feasibility on a single case. Inter-rater agreement was moderate (mKappa (95% CI) = 0.56 (0.46-1.00) for the first round and 0.55 (0.44-1.00) for the second round) and intra-rater agreement was good (mKappa (95% CI) = 0.77 (0.47-1.00)). Criterion validity showed a 78 (73-84)% correctness versus gold standard. CONCLUSION: A preliminary primary heart involvement in systemic sclerosis consensus-based definition was created and partially validated, for use in future clinical research.
