Modern medicine has evolved rapidly, moving from purely symptomatic treatment toward advanced therapies that target the root cause of disease. One such innovation is therapeutic blood purification, which helps remove harmful substances from the bloodstream. This approach has become a cornerstone in treating autoimmune, neurological, hematological, and metabolic disorders.
At leading international medical centers such as swiss health clinic, advanced blood therapies are increasingly used to manage complex, chronic, and treatment-resistant conditions. Among these therapies, the use of an apheresis machine stands out as one of the most effective and versatile tools in modern medicine.
Apheresis is not a single treatment but a family of procedures designed to separate and remove specific components from the blood such as plasma, white blood cells, red blood cells, platelets, antibodies, toxins, or lipids while returning the rest to the patient. This selective removal allows physicians to directly reduce disease-causing factors, often achieving faster and more targeted results than medication alone.
This comprehensive guide explores what diseases are treated using an apheresis system, why it is used, the different types of apheresis procedures, their advantages and benefits, how the treatment process works, and what patients can expect before, during, and after therapy. Whether you are a patient, caregiver, or healthcare professional, this article provides a clear, evidence-based overview of this powerful medical technology.
Why Apheresis Is Used in Modern Medicine
Traditional treatments often rely on medications to suppress symptoms or modify disease progression. However, many diseases are driven by harmful substances circulating in the bloodstream such as autoantibodies, immune complexes, inflammatory cytokines, toxins, or excess lipids. In such cases, medications alone may not be sufficient, or they may take weeks or months to show results.
Apheresis offers a direct, mechanical method to remove these disease-causing substances from the blood. This makes it especially valuable in:
- Autoimmune diseases
- Neurological disorders
- Hematological conditions
- Metabolic and lipid disorders
- Severe infections and inflammatory syndromes
- Organ transplant medicine
The core reasons for using apheresis include:
- Rapid Symptom Relief
By removing harmful blood components, apheresis can lead to faster improvement in symptoms compared to drug therapy alone. This is particularly critical in acute or life-threatening conditions.
- Targeted Therapy
Instead of suppressing the entire immune system, apheresis selectively removes specific pathological substances, reducing the risk of systemic side effects.
- Adjunct to Standard Treatment
Apheresis is often used alongside medications, biologics, or immunotherapies to enhance their effectiveness and speed recovery.
- Treatment for Drug-Resistant Conditions
Some diseases do not respond well to conventional treatments. In such cases, apheresis offers an alternative or supportive therapy.
- Detoxification and Blood Purification
Apheresis is used to remove toxins, heavy metals, abnormal proteins, and metabolic waste products that contribute to disease.
For these reasons, advanced medical institutions, including swiss health clinic, integrate apheresis into personalized treatment plans for complex and chronic illnesses.
Types of Apheresis Procedures
Apheresis is not a single technique but a group of specialized procedures, each targeting different blood components. The most common types include:
- Plasmapheresis (Plasma Exchange)
This procedure removes plasma (the liquid part of blood) and replaces it with donor plasma or a plasma substitute. It is commonly used to eliminate autoantibodies, immune complexes, and toxins.
- Immunoadsorption
Instead of discarding plasma, this technique passes plasma through special filters or columns that selectively remove antibodies or immune complexes. The cleansed plasma is then returned to the patient.
- Leukapheresis
This procedure removes excess white blood cells, often used in leukemia or severe inflammatory conditions.
- Erythrocytapheresis
Red blood cells are selectively removed and replaced, used in diseases like sickle cell anemia or malaria.
- Thrombocytapheresis
Platelets are removed, typically in conditions with dangerously high platelet counts.
- LDL Apheresis
This specialized technique removes low-density lipoprotein (LDL) cholesterol from the blood, used in patients with severe hypercholesterolemia.
- Photopheresis (Extracorporeal Photochemotherapy)
White blood cells are collected, treated with a photosensitizing agent and ultraviolet light, and then returned to the patient. This is often used in immune-mediated conditions.
Each of these procedures utilizes an apheresis machine designed for precise separation and filtration of blood components, ensuring both safety and effectiveness.
Diseases Treated Using an Apheresis Machine

This helps determine whether apheresis is appropriate and which type of procedure is best.
Step 2: Treatment Planning
A personalized treatment plan is developed, specifying:
- Type of apheresis
- Number of sessions
- Frequency and duration
- Replacement fluids or filters used
Step 3: Vascular Access
A catheter or large-bore intravenous line is placed in a vein (usually in the arm or neck) to allow blood to flow into and out of the apheresis machine.
Step 4: Blood Processing
During the procedure:
- Blood is drawn into the machine.
- The targeted component is separated and removed.
- The remaining blood components are returned to the patient along with replacement fluids if needed.
Sessions typically last 1.5 to 4 hours, depending on the type of procedure and patient condition.
Step 5: Monitoring and Safety
Throughout the session:
- Vital signs are continuously monitored.
- Blood pressure, heart rate, and oxygen levels are checked.
- The patient is observed for any discomfort or side effects.
Step 6: Post-Treatment Care
After the session:
- Patients may rest briefly.
- Hydration and nutrition are encouraged.
- Follow-up tests assess treatment effectiveness.
Step 7: Ongoing Management
Many conditions require multiple sessions or maintenance therapy. Physicians adjust treatment based on clinical response and laboratory results.
