Plasma concentrations of various cytokines monitored for 24 h. Ten patients with polymyalgia rheumatica (PMR) and seven non-PMR control subjects were studied before treatment and during the 14th day of treatment with 20 mg of prednisolone. Values are mean ± SEM. Smoothed curves are included. Inverted open triangles, Variation with time in each of the groups (2P < 0.05). Open squares, Difference between untreated patients and control subjects (2P < 0.05). Filled squares, Effect of prednisolone (2P < 0.05) in both patients and control subjects. IL interleukin, TNF tumor necrosis factor
