Abstract: Rheumatoid arthritis (RA) is an autoimmune disease of unknown aetiology characterized by presence of chronic symmetric synovitis, which leads to the formation of joint erosions. Generally recommended method for activity assessment of RA is so called Disease Activity Score (DAS). In early RA when low disease activity is present with oligo- or monoarthritis antimalarials are drugs of choice, while sulfasalazine (SAS) is recommended in cases with medium activity without erosions. Initial treatment with methotrexate (MTX) or leflunomide (LEF) should be applied in a very active polyarthritis with a rapid development of erosions. MTX is often combined with other disease modifying drugs (DMARD) and the blockers of tumour necrosis factor alpha (TNF-alpha). LEF is to be administered to the patients in whom the other DMARD are contraindicated or not tolerated. In established RA with oligo- or monoarthritis with permanent low activity SAS is DMARD of choice. In cases with insufficient response and medium activity MTX is used and if it is inefficient LEF or combination of DMARD should be considered. In a very active disease with a rapid evolution of erosions high doses of MTX or LEF are recommended. When extraarticular symptoms of RA are present azathioprine is to be applied and in case of involvement of vital organs cyclophosphamide should be used. When DMARD are failing or contraindicated TNF-alpha blockers are to be applied. When one TNF-alpha blocker is inefficient it should by replaced by another one from the same group or another biological should be used. For indication of biologicals the activity limit is DAS28 5.1 and the decrease of DAS28 more than 1.2 is an efficacy criterion. Nonsteroidal antirheumatic drugs are an important part in the management of RA, and also corticosteroids are often of used in oral or parenteral form. To the complex therapy of RA nonpharmacological means are usually implemented--different physical procedures and various surgeries.

Abstract: Autoimmune diseases (AID) result from the impairment of the effector and/or recognition phase of the immune response. The autoimmune process plays a crucial role in the pathogenesis of the systemic lupus erythematosus (SLE), systemic sclerosis (SSc), rheumatoid arthritis (RA), and their treatment is therefore largely based on immunosuppression. However, some patients do not respond to its standard doses. The disease becomes intractable with the survival rate comparable to that of some haematological malignancies, or patients become soon handicapped with very poor quality of life, depending on continual administration of high doses of steroids. The new hope for those patients becomes therapy with high dose myelo- and immuno-ablative chemotherapy with autologous hematopoietic progenitor cell support (PBPC). Tens of patients with intractable forms of AID were transplanted in the pilot clinical studies with promising results. The most frequent indications included: SLE, SSc, and RA. Final conclusion of the therapeutic effects will be drawn from the analysis of larger trails.
