Insights
Systemic sclerosis (SSc) patients often develop digital ulcers (DU). Bosentan effectively prevents new digital ulcers and shortens acute phases, though current therapy guidelines are not fully implemented in practice.
Area of Science:
- Rheumatology
- Dermatology
- Vascular Medicine
Background:
- Digital ulcers (DU) affect up to 60% of systemic sclerosis (SSc) patients, significantly impacting quality of life and morbidity.
- Current utilization of authorized medicines and adherence to therapy guidelines for SSc-associated DU remain unclear.
Purpose of the Study:
- To investigate current treatment standards for the therapy and prevention of SSc-associated DU.
- To analyze the effect of DU treatment on disease progression.
Main Methods:
- A retrospective healthcare study involving an online survey of 83 physicians.
- Analysis of 161 case studies of SSc patients with DU.
Main Results:
- Physicians commonly prescribed topical therapies, calcium channel blockers, iloprost, and endothelin receptor antagonists for active DU.
- Bosentan and iloprost were used in 90% of acute DU episodes.
- Preventive treatment for DU was administered in only 50% of DU-free episodes.
- Bosentan, used in 57% of DU-free episodes for prevention, shortened subsequent acute phases by 32% and increased time to new DU onset by 16%.
Conclusions:
- Bosentan demonstrates efficacy in preventing new digital ulcers in DU-free episodes and potentially during acute phases.
- Therapy recommendations for DU treatment are not consistently implemented in clinical practice.
- Increased attention to digital ulcer management in systemic sclerosis is warranted.
Background:
Digital ulcers (DU) affect up to 60 % of patients with systemic sclerosis (SSc) and have a considerable impact on quality of life and morbidity. It is unclear to what extent authorised medicines are used, and if therapy guidelines are implemented in everyday practice.
Method:
This retrospective health care study examined current standards of treatment for therapy and prevention of SSc-associated DU in an online survey with 83 physicians. Additionally, data from 161 case studies of SSc patients with DU were analysed, and the effect of DU treatment on the course of the disease determined.
Results:
For treatment and prevention of active DU, physicians predominantly indicated topical therapies, calcium channel blockers, iloprost and endothelin receptor antagonists. According to the case studies, 90 % of episodes with acute DU were treated with bosentan and iloprost in mono- or combination therapy. Preventive treatment was only administered during 50 % of episodes without DU, even after three or more phases with active DU. For the prevention of new DU, bosentan was used in mono- or combination therapy in 57 % of episodes without DU. Bosentan therapy during prevention shortened the following acute phase by 32 %. Additionally, continuous treatment with bosentan in acute and prevention phases reduced the duration of the following acute phase and increased the time to onset of new DU by 16 %. Moreover, bosentan stabilised the number of new DU.
Conclusion:
In summary, these data confirm the efficacy of bosentan in preventing new DU when used in DU-free episodes and possibly also in phases of acute DU. Therapy recommendations for the treatment of DU are currently not fully implemented. In the future, even more attention should be paid to DU therapy.
