[Fast and efficient healing of scleroderma-associated acral ulcers with sildenafil]

Area of Science:

• Vascular Medicine
• Rheumatology
• Pharmacology

Background:

• Progressive systemic sclerosis (PSS) frequently causes debilitating acral ulcers, often resistant to standard treatments.
• Pulmonary arterial hypertension (PAH) is a severe complication of PSS, contributing to patient morbidity.

Observation:

• A 35-year-old male with severe PSS, PAH, and refractory acral ulcers was treated with oral sildenafil.
• Sildenafil, a phosphodiesterase-5 inhibitor, enhances endothelial cGMP, promoting vasodilation.

Findings:

• The patient experienced rapid improvement in dyspnea and increased walking distance within one week of sildenafil administration.
• Complete and sustained healing of all acral ulcers was achieved within five weeks of treatment.
• Sildenafil demonstrated significant efficacy in managing scleroderma-associated refractory acral ulcers.

Implications:

• Sildenafil represents a promising therapeutic option for refractory acral ulcers in patients with progressive systemic sclerosis.
• This case highlights the potential of targeting phosphodiesterase-5 pathways for managing complex vascular complications in autoimmune diseases.
• Further research into sildenafil's role in PSS management, particularly for vascular and dermatological manifestations, is warranted.
