Platelet-rich plasma for the treatment of scleroderma-associated ulcers: a single-center experience and literature review.

Systemic sclerosis (SS) is a complex connective tissue disease characterized by vasculopathy and progressive fibrosis, primarily considered an autoimmune disorder. SS can affect multiple organs and tissues, including the skin, respiratory, gastrointestinal, genitourinary, cardiovascular, and musculoskeletal systems. Skin involvement is common, and SS-related ulcers, especially digital ulcers, occur in roughly 50% of patients. These ulcers not only cause pain but also significantly impact patients' quality of life, and in severe cases, they can lead to infection, gangrene, and amputation. The search for novel therapies for scleroderma-related ulcers remains an ongoing research area. Platelet-rich plasma (PRP) has been investigated as a potential treatment for difficult-to-heal ulcers, including diabetic, pressure, and vascular ulcers. In this study, we share our experience in treating scleroderma ulcers with PRP. Ten patients with confirmed SS and chronic skin ulcers lasting at least six weeks, which had not responded to conventional treatments, were selected for the study. Homologous PRP gel was prepared and applied once a week for up to eight weeks. The ulcers were documented photographically before and after PRP treatment, and pain levels were assessed using a visual analog scale (VAS). We also conducted a systematic review of the literature focusing on the use of PRP in the setting of SS. The results from our casuistry showed that the ten patients, including eight females and two males with a median age of 52.5 years, had ulcer sizes ranging from 0.78 cm
