The invention concerns the field of human auto-immune and/or inflammatory diseases, and more specifically the use of arsenic compounds for the preparation of drugs intended for the treatment and/or prevention of skin injuries associated with auto-immune and/or inflammatory diseases in a human subject. The invention concerns an arsenic compound As2O5 for use in the treatment and/or prevention of skin injuries associated with auto-immune and/or inflammatory diseases in a human subject, a pharmaceutical composition comprising an arsenic compound As2O5, preferably for the treatment and/or prevention of skin injuries associated with auto-immune diseases in a human subject, and products containing an arsenic compound As2O5 and an arsenic compound As2O3 as a combination product for simultaneous, separated or time-spread use in the treatment and/or prevention of skin injuries associated with auto-immune diseases in a human subject.
Please help me write a proper abstract based on the patent claims. CLAIM: 1. A composition comprising a combination of arsenic compounds, said combination comprises the arsenic compound As2O5 and in addition at least one arsenic compound selected from the list consisting of As2O3, As2O5, As4O6, As2S2, As2S3, As2S5 and As4S4. 2. The composition according to claim 1, characterized in that said combination comprises the arsenic compound As2O5 and the additional arsenic compound As2O3. 3. The composition according to claim 1 characterized in that said combination consists of the arsenic compound As2O5 and the additional arsenic compound As2O3. 4. The composition according to claim 2, characterized in that it comprises between 0.01% and 0.15% of the arsenic compound As2O5 relative to the total weight of the composition, and between 0.05% and 5% of the arsenic compound As2O3 relative to the total weight of the composition. 5. The composition according to claim 1, characterized in that it is formulated in a form suitable for topical administration, in particular dermatological administration. 6. The composition according to claim 1, characterized in that it is formulated in a form suitable for systemic administration. 7. The composition according to claim 1, for use in the treatment and/or prevention of skin lesions associated with autoimmune and/or inflammatory diseases in a human subject. 8. Products containing an arsenic compound As2O5 and an additional arsenic compound selected from the list consisting of As2O3, As2O5, As4O6, As2S2, As2S3, As2S5 and As4S4, as a combination product for simultaneous, separate or sequential use in the treatment and/or prevention of skin lesions associated with autoimmune and/or inflammatory diseases in a human subject. 9. The products for use according to claim 8, characterized in that they contain an arsenic compound As2O5 and the additional arsenic compound As2O3. 10. A method for treating and/or preventing skin lesions associated with autoimmune diseases in a human subject, comprising a step of administering to said subject a composition according to claim 1. 11. The method according to claim 10, wherein the application of As2O5 is alternated with the administration of at least one additional arsenic compound selected from the list consisting of As2O3, As2O5, As4O6, As2S2, As2S3, As2S5 and As4S4. 12. The method according to claim 11, wherein the application of As2O5 is alternated with the administration of the arsenic compound As2O3. 13. A method for treating and/or preventing skin lesions associated with autoimmune diseases in a human subject, comprising administering products according to claim 8. 14. The method according to claim 13, wherein the application of As2O5 is alternated with the administration of at least one additional arsenic compound selected from the list consisting of As2O3, As2O5, As4O6, As2S2, As2S3, As2S5 and As4S4. 15. The method according to claim 13, wherein the application of As2O5 is alternated with the administration of the arsenic compound As2O3.
