СПЕЦИФИЧЕСКИЙ ДЛЯ ПАЦИЕНТА ИММУНОАДСОРБЕНТ ДЛЯ ЭКСТРАКОРПОРАЛЬНОГО АФЕРЕЗА И СПОСОБ ЕГО ПОЛУЧЕНИЯ

Номер: RU2167705C2

Изобретение может быть использовано в медицине для лечения аутоиммунных заболеваний. Заявлен иммуноадсорбент для экстракорпорального афереза, специфический для каждого пациента. Он состоит из антигенов и антител, ковалентно связанных с активированным биосовместимым твердым материалом-носителем. Антигены и антитела получены путем расщепления иммунокомплексов, изолированных из крови или других жидкостей тела того же самого пациента, для которого данный иммуноадсорбент предназначен. Способ получения иммуноадсорбента включает выделение иммунокомплексов из крови и/или других жидкостей тела пациента, очистку их и расщепление на антитела и антигены и ковалентное связывание их с активированным биосовместимым материалом-носителем. Изобретение позволяет лечить хронические формы аутоиммунных заболеваний и заболеваний, связанных с дизрегулированием иммунной системы. При этом исключается опасность передачи возбудителей таких заболеваний, как ВИЧ и гепатит. 2 с. и 5 з.п. ф-лы, 7 ил., 7 табл.

A method and apparatus for continuous removal of submicron sized artificial oxygen carriers (rAOC) and other materials such as cancer cells and bacteria from blood and other liquids. A centrifuge rotor having a curved shape is offset on a spinning rotor base and creates contiguous areas of low to high centrifugal force depending on the distances from the axis of the rotor base. This creates a density gradient field that separates materials of different densities input to the centrifuge that exit via different outputs. A monitor detects any red blood cells (RBC) with the rAOC before they exit the centrifuge. If there are any RBC detected logic circuitry changes the speed of rotation of the rotor, and the flow rate of pumps inputting and removing separated blood and rAOC to and from the centrifuge until there are no RBC in the rAOC exiting the centrifuge.

PURIFICATION APPARATUS AND METHOD EMPLOYING A REGENERABLE LIGAND

Номер: CA1248325A

There is disclosed a system and apparatus for purifying a fluid stream which employ a fixed ligand to absorb a ligate carried in the fluid stream. The system and apparatus each includes a bed of ligands affixed to a semipermeable membrane. The ligand has a binding constant which, in the environment normally present in the fluid stream, will predictably bind the ligate and thus remove it from the fluid stream. An agent which regenerates the ligand is conveyed to the ligand bed by diffusion across the semipermeable membrane. The diffused agent breaks the ligateligand bond. The ligand is regenerated for subsequent use, and the ligate is freed for disposal.

The invention is directed to the removal of serum gal-3 from circulation by plasmapheresis using gal-3 binding agents in either a fixed bed, or in a form easily removed, such as by being complexed with magnetic particles. This method, on its own, brings a sharp reduction and relief from the inflammation and fibroses that can be induced by circulating gal-3. The process may be combined with the administration of gal-3 binding agents, such as modified citrus pectin, to further lower unbound gal-3 levels, to the point where gal-3 in the tissues may be addressed. This method may also be combined with removal of TNF receptors to provide an effective treatment for cancer.

The present invention generally relates to systems and methods for targeted removal of a substance or biomolecule such as a protein from a biological fluid, such as blood. In some cases, the blood may be withdrawn from a subject, treated, and returned to the subject. Previous techniques for removal of biological materials from blood, such as hemodialysis and plasmapheresis, were generally non-specific (i.e., they removed a multitude of proteins/toxins from the blood). By contrast, novel methods and devices described herein are capable of removing specific or single substances such as proteins from biological fluids such as blood in a specific manner. Such highly specific protein removal has a broad array of clinical applications, including treatment of inflammatory conditions and autoimmune diseases.

Systems and methods for extracorporeal blood modification

Номер: US20150132312A1
Принадлежит: Childrens Medical Center Corp

The present invention generally relates to systems and methods for targeted removal of a substance or biomolecule such as a protein from a biological fluid, such as blood. In some cases, the blood may be withdrawn from a subject, treated, and returned to the subject. Previous techniques for removal of biological materials from blood, such as hemodialysis and plasmapheresis, were generally non-specific (i.e., they removed a multitude of proteins/toxins from the blood). By contrast, novel methods and devices described herein are capable of removing specific or single substances such as proteins from biological fluids such as blood in a specific manner. Such highly specific protein removal has a broad array of clinical applications, including treatment of inflammatory conditions and autoimmune diseases.
