Background: Lichen sclerosus (LS) is a complex autoimmune chronic inflammatory skin disease that leads to tissue sclerosis and atrophy. LS is considered a non-obligate pre-cancerous disease. The treatment of LS is still currently being codified. Actually, the first-line treatment consists in ultra-potent local steroid. Polydeoxyribonucleotide (PDRN), an A2A receptor agonist, has demonstrated anti-inflammatory effects through the reduction of Cytokine production and growth stimulation of fibroblast, as well as through their specific proteins synthesis. PDRN also seemed to promote proliferation of human pre- adipocytes, which constitute the most abundant source of adult stem cells. Objective: To evaluate the efficacy of intra-dermal administration of Polydeoxyribonucleotide (PDRN) solution in adult male patients suffering from mild to severe genital Lichen sclerosus, as compared to administering triamcinolone acetonide intralesional injection without PDRN. Patients/Methods: A group of male patient (n=28; aged 25 to 65 year-old) with a history of mild to severe genital lichen sclerosus (LS) and with a moderate to severe impairment of sexual relationship, selected from our dermo-venereological private practice centre, were enrolled for this clinical study. All patients gave their informed consent to treatment. Inclusion criteria for participation in the study included =18-year old males with first occurrence of genital LS, biopsy-proven. The disease activity at baseline was evaluated as assessed by the investigator on the Investigator?s Global Assessment (IGA). A group of these patients (Group A; n=14) were treated with sub-dermal injections of Polydeoxyribonucleotide solution (5625 mg of PDRN in a 3-mL) plus sub-dermal injections of Triamcinolone acetonide (TA) 10mg solution, on site of pathology, twice a month for 4 months. The remaining patients (Group B; n=14) were treated with only sub-dermal injection of TA 10mg solution. Results: After therapy, in all patients of group A (n=14) there has been a marked regression of most of clinical pathological signs of LS according to IGA assessment, while there has been a slight to moderate improvement in all group B patients (Group B, n=14). Conclusions: On site intra-dermal administration of PDRN, associated with TA 10mg solution therapy, seemed to promote a cellular and anti-inflammatory pathway that could be associated with a marked clinical improvement of Lichen sclerosus.
