The phenotypic characteristics of peripheral blood lymphocytes were investigated in 22 patients suffering from active polymyalgia rheumatica/giant cell arteritis (PMR/GCA) prior to steroid treatment. We observed a significant reduction in the absolute number and the relative percentage of CD4-, CD8+ and CD3+, CD16+ and/or CD56+ cells compared to controls. Fifteen patients were investigated prospectively over a 6-month period of prednisone therapy. At the end of the study CD4-CD8+ cells had increased significantly compared to baselines, CD3+ CD16+ and/or CD56+ cells remained significantly lower when compared to controls. We did not observe any abnormalities in the absolute number and percentage of HLA-DR+ T lymphocytes, CD5+ B cells and NK cell phenotypes before or during steroid treatment. Our study confirms that there was significant increase in the absolute number of CD8+ T cells during steroid treatment in the PMR/GCA patients, but indicates the persistence of an immunological alteration despite the control of disease manifestations.

D011111 Polymyalgia Rheumatica A syndrome in the elderly characterized by proximal joint and muscle pain, high erythrocyte sedimentation rate, and a self-limiting course. Pain is usually accompanied by evidence of an inflammatory reaction. Women are affected twice as commonly as men and Caucasians more frequently than other groups. The condition is frequently associated with GIANT CELL ARTERITIS and some theories pose the possibility that the two diseases arise from a single etiology or even that they are the same entity.
