Aims of the study to evaluate the radiologically detected progression of joint damage in patients with psoriatic arthritis (PA) treated with cyclosporin-A (CsA) and to look for clinical and/or immunological parameters that might predict outcome. Twenty-four out-patients suffering from active PA entered a 2-year open prospective study on low-dose CsA (starting dose 3 mg/kg/day). Fifteen patients completed the study. Plain radiographs of hands and feet at study entry and at the end of follow-up were compared for the number of eroded joints. Serum-soluble IL-2 receptor (sIL-2R) levels were available in 13/15 patients before CsA therapy, after 6 months and after 2 years. The mean number of eroded joints per patient increased significantly during the study period (P = 0.017). Nine patients had less than two new eroded joints (responders) while the remaining six patients had five or more new eroded joints (non-responders). Serum sIL-2R levels were in the normal range after 6 months and 2 years of CsA treatment in all the responder patients and were above the 95th percentile of the control population in the six non-responders. We did not find any other demographical, clinical, radiological or laboratory parameter predictive of outcome in conclusion. (1) CsA seems to be able to control the 2-year progression of the radiologically measured damage in peripheral joints in 60% of PA patients. (2) A normal serum sIL-2R level after 6 months of therapy seems to have a prognostic value for a good outcome in PA patients treated with CsA.

Interleukin (IL)-9 is a 28-30 kDa monomeric glycosylated polypeptide belonging to the IL-7/IL-9 family of proteins that bind to a composite receptor consisting of the private receptor IL-9R and the IL-2 receptor, gamma (IL-2RG), a common gamma subunit shared by the receptors of many different cytokines. The IL-9R is expressed widely and IL-9 impacts a number of effector cells, such as effector T cells, B cells, innate lymphoid cells, mast cells, polymorphonuclear cells, epithelial cells and smooth muscle cells, playing an important role in regulating inflammatory immunity. The critical role of IL-9 in promoting cellular and humoral immune responses makes it an important focus of potential therapeutic interventions. Recently, a defined subset of T helper type cells, Th9 cells, has been identified by the potent production of IL-9. The involvement of the Th9 cell subset has been described in many types of inflammatory diseases, namely atopic diseases, helminth infections, experimental autoimmune encephalomyelitis and ulcerative colitis. In this review, we summarize the IL-9 biological activities, highlighting roles for IL-9 and Th9 cells in rheumatoid and psoriatic arthritis, systemic vasculitis, systemic lupus erythematosus and systemic sclerosis.
