A study of relationship between serum SIL-2R titer and severity of involved muscles in patients with myasthenia gravis / 临床神经病学杂志

ABSTRACT

Objective To study the relationship between serum soluble interleukin-2 receptor (SIL-2R) titer and severity of involved muscles and transient aggravation due to large dose corticosteroid therapy in patients with myasthenia gravis.Methods 30 severe patients with MG were classified according to improved Osserman method. The involved voluntary muscles were divided into seven groups. The severity of MG was recorded with five grades and four parts formulation. The absolute integral was taken as the index of MG degree. ELISA was used to measure the titer of serum SIL-2R.Results Remarkable difference was found between patient group and control group both in the SIL-2R titer and the severity of MG(all P0.05) when the cases aggravated transiently during large-dose corticosteroid therapy.Conclusion Cell immunity is abnormal in patients with MG. SIL-2R may reflect the severity of involved muscles.
