Glucocorticoid is widely used in clinical treatment. Recently, there was research about
glucose fluctuations under low-dose and pulse steroid therapy in elderly patients with active
autoimmune diseases. Through this prospective trial, the investigators wanted to know the
blood glucose characteristics under high dosage glucocorticoid (1-2 mg/kg/day prednisone or
equivalent) in young patients (30-40 years) with active autoimmune diseases with or without
low-dose glucocorticoid maintenance. The investigators used continuous glucose monitoring for
72 hours to get a better understanding of the glucose levels.
