Abstract
A new immunoadsorbent (I-02), adsorbing rheumatoid factor and immune complex, has been developed. Batchwise adsorption studies revealed that I-02 is more efficient than Protein A- Sepharose CL4B. During ex vivo I-02 plasma perfusion in the dogs, coagulation and fibrinolysis factors were almost constant. Blood biochemical parameters were within normal limits. Platelets aggregation value is almost constant. I-02 plasma perfusion was carried out in the patient with chronic rheumatic arthritis with satisfactory results.
