[Characterization of unusual macro CK1 of IgG3kappa-cK-MM type detected in the serum of a patient with idiopathic thrombocytopenic purpura].

An unusual creatine kinase (CK) band detected in the serum of a patient with idiopathic thrombocytopenic purpura (ITP) was studied. The number of platelets of the patient decreased to 2.3 x 10(4)/microL, and serum CK and CK-MB activities increased to 899 and 62.
