Brief Summary

Digital ulcers (DUs) in scleroderma result from recurrent Raynaud's phenomenon (RP) and microtrauma with high impact on quality of life, management of DUs is a great challenge for clinicians. Medical use of ozone (triatomic oxygen) was initiated in the 19th century. Ozone has multiple therapeutic effects in wound healing due to the property of releasing nascent oxygen, which has been shown to stimulate antioxidant enzymes.

Outcome Measures

Primary Outcomes (2)

  • scleroderma ulcer healing

    Ulcer size measurement in cm

    4 months

  • Pain

    Using 10 cm scale

    4 months

Secondary Outcomes (1)

  • Ulcer biopsy

    4 months

Study Arms (2)

ozone treated group

EXPERIMENTAL

Therapeutic effects will be graded into 4 levels from grade 0 (no change) to grade 3 (wound healing). The wound sizes will be measured at baseline and day 20, respectively. Tissue biopsies will be performed at baseline and day 20, expressions of VEGF, ETAR and AT1R autoantibodies proteins will be determined by immune-histochemical examinations

Device: the ozone generator device (Human Pro medic, German)

non-ozone treated group

NO INTERVENTION

Therapeutic effects will be graded into 4 levels from grade 0 (no change) to grade 3 (wound healing). The wound sizes will be measured at baseline and day 20, respectively. Tissue biopsies will be performed at baseline and day 20, expressions of VEGF, ETAR and AT1R autoantibodies proteins will be determined by immune-histochemical examinations

Interventions

noninvasive oxygen-ozone treatments with 52 ug/mL ozone (total volume: 20-50 mL) in a special bag for 30 min per day for 20 days using the ozone generator device (Human Pro Medic, German)

ozone treated group
