  Purpose
  • Systemic sclerosis (scleroderma; SSc) is a connective tissue disease characterized by a progressive fibrosis of the skin and visceral organs.
  • A diffuse cutaneous microvascular damage occurs in 30-50% of patients, often leading to digital ulcers development, responsible for pain, functional disability, disfiguring scars, digital bony reabsorption, infection and osteomyelitis.
  • Although the availability of drugs as i.v. prostacyclin analogs, oral vasodilating agents, oral phosphodiesterase-5 inhibitors, oral endothelin receptor blockers has improved the prognosis, digital ulcers are frequently refractory to the medical treatment.
  • Preliminary data seems to demonstrate a pivotal role played by some growth factors (PDGF, TGF beta 1-2, IGF) in the process of ulcers healing: tissue regeneration and re-epithelization. Alpha-granules in the platelets store these factors in significant amount.
  • Recently, the application of a gel rich in platelets, prepared from donors’ plasma taken by apheresis, seems to be beneficial to enhance pressure and vascular ulcers healing.
  • On the basis of these considerations we expect that application of a platelet gel, combined with advanced dressing and conventional medical therapy, makes a more rapid healing of digital ulcers in patients with systemic sclerosis. We decided to conduct a double blind RCT to test this hypothesis
