Abstract (original English)

Digital ulcers (DUs) comprise the main manifestation of vasculopathy and are a major cause of disability in patients with systemic sclerosis (SSc). A literature search in Web of Science, PubMed and Directory of Open Access Journals was performed in December 2022 to identify articles published in the last decade regarding the management of DUs. Prostacyclin analogues, endothelin antagonists and phosphodiesterase 5 inhibitors have shown promising results both as a stand-alone treatment and in combination for the treatment of existing and prevention of new DUs. Moreover, autologous fat grafting and botulinum toxin injections, although not readily available, can be of use in recalcitrant cases. Many investigational treatments with promising results could pave the way for a paradigm shift in the treatment of DUs in the future. Despite these recent advances, challenges remain. Better-designed trials are of paramount importance to optimise DU treatment in the years to come. Key Points • DUs are a major cause of pain and reduced quality of life in patients with SSc. • Prostacyclin analogues and endothelin antagonists have shown promising results both as a stand-alone treatment and in combination for the treatment of existing and prevention of new DUs. • In the future, a combination of more powerful vasodilatory drugs, perhaps in conjunction with topical approaches, may improve outcomes
