Impairment of hand function burdens both limited and diffuse cutaneous subsets and therefore could be targeted as \u2018basket\u2019 endpoint in SSc. Nevertheless, its natural history in current standard of care is not well characterised, limiting the design of targeted trials. The aim of this study is to describe prevalence, natural history and clinical factors associated with hand function deterioration in a longitudinal, multicentre, observational SSc cohort.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods<\/jats:title>\n                  <jats:p>Hand function was captured through the validated Cochin Hand Function Scale in patients consecutively enrolled in a multicentre observational study and observed over 24 months. Minimal clinically important differences and patient acceptable symptom state were analysed as previously described.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>Three hundred and ninety-six consecutive patients were enrolled from 10 centres; 201 with complete follow-up data were included in the analysis. Median (IQR) disease duration was 5 (2\u201311) years. One hundred and five (52.2%) patients reported clinically significant worsening. Accordingly, the proportion of patients reporting unacceptable hand function increased over 2 years from 27.8% to 35.8% (p&lt;0.001). Least absolute shrinkage and selection operator analysis identified male gender, disease subset, Raynaud\u2019s Condition Score, tenosynovitis and pain, as some of the key factors associated with worsening hand involvement.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>Hand function deteriorates over time in more than 50% of SSc patients despite available therapies. The analysis of factors associated with hand function worsening supports the involvement of both inflammation, vascular and fibrotic processes in hand involvement, making it a hallmark clinical manifestation of SSc. Our data are poised to inform the design of intervention studies to target this major driver of disability in SSc.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1136\/rmdopen-2023-003216","type":"journal-article","created":{"date-parts":[[2024,1,12]],"date-time":"2024-01-12T12:21:06Z","timestamp":1705062066000},"page":"e003216","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":14,"title":["Clinical trajectories of hand function impairment in systemic sclerosis: an unmet clinical need across disease subsets"],"prefix":"10.1136","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9819-105X","authenticated-orcid":false,"given":"Enrico","family":"De Lorenzis","sequence":"first","affiliation":[{"name":"Leeds Institute of Rheumatic and Musculoskeletal Medicine, University of Leeds, Leeds, UK"},{"name":"Division of Rheumatology, Catholic University of the Sacred Heart, Fondazione Policlinico Universitario A.
