title: [Immune system and rheumatic diseases in the elderly].
abstract: Impairments of the immune system play an important role in all immun-mediated rheumatic diseases. Recently, the following news were reported: · Early aging of the immune system with thymus insufficiency has now been reported for both patients with rheumatoid arthritis and axial spondyloarthritis, without prethymic lack of progenitors at least in rheumatoid arthritis.. · For giant cell arteritis, the most frequent vasculitis in the elderly, an increased expression of IL-17A in temporal artery biopsies coincides with good prognosis and reponse to glucocorticoids.. · Concerning immunosenescence in systemic lupus erythematosus, BAFF appears to have an important role for relapses after B-cell depletion.. For the future it can be anticipated that the use of unified classification criteria for rheumatic diseases (as with the new 2012 EULAR / ACR classification criteria for polymyalgia rheumatica) will ensure better comparability of immunological studies also in the elderly.
