Therapeutic Plasma Exchange

Published with the inputs from Dr Jayameena P, Senior Consultant, Nephrology, Kidney Transplant, Baby Memorial Hospitals - Kozhikode

Therapeutic Plasma Exchange (TPE), also called Plasmapheresis, is a specialized blood purification procedure used to remove harmful antibodies, toxins, or abnormal proteins from the blood.

During this procedure, a portion of the patient’s plasma (portion of blood without RBC) is separated and replaced with fresh plasma or a plasma substitute, helping to control autoimmune diseases, neurological conditions, and certain blood disorders. TPE is performed under expert supervision using advanced apheresis machines at Baby Memorial Hospital’s Intensive Care Unit

What is therapeutic plasma exchange?

Therapeutic plasma exchange is a medical treatment that cleans the blood by removing and replacing plasma. Plasma often contains antibodies or harmful substances that cause disease or interfere with normal body function.

By replacing this plasma, TPE helps the body recover and reduces disease activity in conditions where the immune system is overactive.

When is therapeutic plasma exchange recommended?

TPE is used for a wide range of serious medical conditions, including:

Neurological conditions

• Guillain–Barré Syndrome (GBS)
• Myasthenia Gravis
• Multiple Sclerosis (MS) relapses
• Autoimmune encephalitis

Renal and autoimmune diseases

• Goodpasture’s syndrome
• Lupus nephritis
• ANCA-associated vasculitis

Hematological disorders

• Thrombotic Thrombocytopenic Purpura (TTP)
• Cryoglobulinemia
• Hyperviscosity syndromes

Toxic or metabolic conditions

• Drug overdose or poisoning (when toxin is plasma-bound)
• Hyperlipidemic pancreatitis

Your specialist will determine the need and frequency of TPE based on the disease and clinical response.

How is therapeutic plasma exchange performed?

• The procedure is done in a critical care or apheresis unit under close monitoring.
• Blood is withdrawn from a vein or catheter and passed through a plasma exchange machine.
• The plasma is separated from blood cells using centrifugal or membrane filtration techniques.
• The removed plasma is replaced with donor plasma, albumin solution, or saline.
• The purified blood is then returned to the patient’s circulation.
• Each session usually lasts 2–3 hours and may be repeated over several days as prescribed.

Is plasma exchange safe?

Yes. When performed in a hospital setting by trained specialists, TPE is safe and well-tolerated. Possible but mild side effects include:

• Temporary low blood pressure or dizziness
• Mild tingling due to low calcium levels
• Fatigue after the procedure
• Rare allergic reaction to replacement fluids

At BMH, patients are continuously monitored by nephrologists, intensivists, blood bank officers and trained nurses throughout the procedure to ensure safety and comfort.

How is TPE different from dialysis or hemoperfusion?

TPE is not a kidney support therapy, but an immunomodulatory treatment that alters disease processes by removing harmful plasma components.

What are the benefits of therapeutic plasma exchange?

• Rapid removal of harmful antibodies or toxins
• Reduces disease activity and flare-ups
• Improves neurological and organ function
• Life-saving in acute autoimmune and blood disorders
• Can be repeated safely as needed
• Performed without surgery or general anesthesia

Who performs therapeutic plasma exchange?

TPE is carried out by a multidisciplinary team at BMH, including:

• Nephrologists, Transfusion medicine department and intensivists (to supervise and guide treatment)
• Trained dialysis and apheresis nurses
• Hematologists or neurologists, depending on the disease being treated

What is recovery like after plasma exchange?

• Most patients feel tired but stable after each session.
• Normal activities can often resume the next day.
• Adequate hydration and rest are advised.
• Follow-up blood tests ensure the stability of electrolytes and proteins.
• The number of sessions depends on the underlying condition — typically 3–6 sessions over several days.
