Abstract
Abstract Methods are provided for the treatment of pathological conditions connected with the production of other interferons possessing the damaging action on the cell systems of the organism via the continuous removal of interferon from the organism. This is achieved for example by extracorporeal perfusion of the blood of the patient through the substances absorbing, disintegrating, or inactivating biological activity of interferon. The removal of defective interferon is an effective treatment of cancers and leukemias, and immunodeficiencies.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
141 words
In a method of treating diseases comprising the step of selectively clearing the blood of a patient from interferon using an apparatus having, in continuous fluid communication, an inlet tube, absorbing means for absorbing and thereby removing interferon from the whole blood, and an outlet tube, said method comprising: connecting the inlet tube of said apparatus to a blood vessel of a patient and connecting the outlet tube of said apparatus to a vein of the patient; removing blood from the blood vessel of the patient; passing the removed blood through the absorbing means for absorbing interferon to thereby reduce the amount of interferon in the blood; and returning the blood to the vein of the patient, the improvement comprising: administering normal interferon after completion of the clearance of interferon process and returning the blood containing normal interferon to the patient.
Claim 2
Dependent Claim
141 words
In a method of treating diseases comprising the step of selectively clearing the blood of a patient from interferon using an apparatus having, in continuous fluid communication, an inlet tube, absorbing means for absorbing and thereby removing interferon from the whole blood, and an outlet tube, said method comprising: connecting the inlet tube of said apparatus to a blood vessel of a patient and connecting the outlet tube of said apparatus to a vein of the patient; removing blood from the blood vessel of the patient; passing the removed blood through the absorbing means for absorbing interferon to thereby reduce the amount of interferon in the blood; and returning the blood to the vein of the patient, the improvement comprising: administering normal interferon after completion of the clearance of interferon process and returning the blood containing normal interferon to the patient.
Claim 3
Dependent Claim
171 words
In a method of treating diseases comprising the step of selectively clearing the blood of a patient from interferon using an apparatus having, in continuous fluid communication, an inlet tube, absorbing means for absorbing and thereby removing interferon from the whole blood, and an outlet tube, said method comprising: connecting the inlet tube of said apparatus to a blood vessel of a patient and connecting the outlet tube of said apparatus to a vein of the patient; removing blood from the blood vessel of the patient; separating the removed blood into blood cells and plasma: passing the plasma through the absorbing means for absorbing interferon to thereby reduce the level of interferon within the plasma; combining the plasma having a reduced level of interferon with the blood cells previously removed from the blood; and returning the combined blood cells and plasma to the vein of the patient; the improvement comprising: administering normal interferon after completion of the clearance of interferon process and returning the blood containing normal interferon to the patient.
