Patent Claims:	1. A method of treating at least one autoimmune disease selected from autoimmune polyarthritis and multiple sclerosis, but not treating psoriatic arthritis, comprising administering, to a patient in need of treatment for said at least one autoimmune disease but not for said psoriatic arthritis, an amount of a pharmaceutical preparation effective for treating said at least one autoimmune disease, the pharmaceutical preparation comprising at least one excipient or at least one carrier or at least one combination thereof; and dimethyl fumarate, wherein the only active ingredient for the treatment of the at least one autoimmune disease present in said pharmaceutical preparation is the dimethyl fumarate. 2. The method of claim 1, wherein the dimethyl fumarate is present in an amount of from 10 to 300 mg in the pharmaceutical preparation. 3. The method of claim 1, wherein the dimethyl fumarate is provided in one or more capsules. 4. The method of claim 2, wherein at least 50 mg of dimethyl fumarate is present in the pharmaceutical preparation. 5. The method of claim 2, wherein at least 110 mg of dimethyl fumarate is present in the pharmaceutical preparation. 6. The method of claim 2, wherein at least 120 mg of dimethyl fumarate is present in the pharmaceutical preparation. 7. The method of claim 2, wherein 50 mg of dimethyl fumarate is present in the pharmaceutical preparation. 8. The method of claim 2, wherein 110 mg of dimethyl fumarate is present in the pharmaceutical preparation. 9. The method of claim 2, wherein 120 mg of dimethyl fumarate is present in the pharmaceutical preparation. 10. The method of claim 1, wherein the pharmaceutical preparation is formulated for oral administration. 11. The method of claim 1, wherein the pharmaceutical preparation is formulated as a solid dosage form. 12. The method of claim 1, wherein the pharmaceutical preparation is formulated as microtablets. 13. The method of claim 12, wherein the microtablets are provided in one or more capsules, wherein at least 50 mg of dimethyl fumarate is present in each capsule. 14. The method of claim 13, wherein at least 110 mg of dimethyl fumarate is present in each capsule. 15. The method of claim 14, wherein at least 120 mg of dimethyl fumarate is present in each capsule. 16. The method of claim 12, wherein the microtablets are enteric-coated. 17. The method of claim 16, wherein the microtablets have a mean diameter in the range of 0.3 mm to 2.0 mm, exclusive of any coating on the microtablets. 18. The method of claim 17, wherein the microtablets have a mean diameter of 2.0 mm, exclusive of any coating on the microtablets. 19. The method of claim 1, the pharmaceutical preparation comprising at least one carrier. 20. The method of claim 1, the pharmaceutical preparation comprising at least one excipient. 21. The method of claim 1, the pharmaceutical preparation comprising at least one excipient and at least one carrier.
