[Correlation of IgG Subclass with Blood Cell Parameters in Patients with Autoimmune Hemolytic anemia].

Objective: To investigate the correlation of IgG subclasses with blood cell parameters in the patients with autoimmune hemolytic anemia (AIHA).

Methods: Thirty-four patients with AIHA (except C3d types) of immune complex type (IgG+C3d) and single IgG type, including 26 cases of primary AIHA and 8 cases of secondary AIHA from December 2010 to August 2016 in our hospital were selected and enrolled in AIHA group; 30 healthy persons were selected and enrolled in healthy control group. The levels of IgG subclasses in blood plasma were detected by double antibody sandwich ELISA in healthy persons and AIHA patients, at the same time.
