ABSTRACT:
Disclosed is a multimodal method and apparatus for extracorporeally treating certain blood borne infections, such as the infection of T-lymphocytes with the Human Immunodeficiency Virus. The method and apparatus of the invention includes (a) hyperthermic, (b) mechanical shear inducing, and (c) irradiation treatment modalities. These three treatment modalities may be carried out separately, in any order, or simultaneously, in any combination. The irradiation treatment mode preferably includes methods and means for subjecting at least a fraction of the blood to ultraviolet and/or x-ray and/or laser radiation. Before the blood is withdrawn from the human subject a chemical agent such as heparin may be administered to the subject for purposes of inducing lymphocyte migration from the lymph system into the circulatory system. Following extraction of a desired maximal volume of blood from the human subject, volume extenders may be mixed with the blood, thereby adjusting the extracorporeal blood volume as required or desired. Following completion of the extracorporeal treatment(s) the treated blood is returned to the patient.
