How Plasmapheresis Dialysis Helps in Kidney Treatment?

When we think of kidney disease, we often blame infections or diabetes. However, there are times when the body’s own immune system turns against the kidneys, creating inflammation and serious complications. When this happens, doctors may suggest plasmapheresis, also called plasmapheresis dialysis, as part of the treatment plan. 

Although plasmapheresis and dialysis are different procedures, they are sometimes grouped as ‘plasmapheresis-dialysis' because both use a machine to filter unwanted substances from the blood. We will explore this difference and more about plasmapheresis in this blog. Let’s understand this step by step.

What Is Plasmapheresis Dialysis?

To understand plasmapheresis dialysis, we first need to know what plasma is. You may have learnt in school that blood has four main parts:

• Red blood cells
• White blood cells
• Platelets
• Plasma (the yellowish liquid part)

Plasma carries proteins, antibodies and other substances around the body. Sometimes, harmful antibodies or immune proteins in the plasma attack the kidneys. Some common questions that one may have are:

What is plasmapheresis therapy?

It is a medical procedure in which plasma is removed from the blood and replaced with a clean fluid, usually donor plasma or a special solution.

Is plasmapheresis dialysis the same as regular dialysis?

The answer is no. Regular dialysis removes waste and extra fluid. Plasmapheresis removes harmful immune substances from plasma.

What is plasmapheresis treatment used for?

It is mainly used in autoimmune diseases, severe kidney inflammation and some transplant-related conditions.

How Does Plasmapheresis Dialysis Work?

If you are recommended to get plasmapheresis, knowing how plasmapheresis is done can reduce anxiety before the procedure. Here is how plasmapheresis dialysis works:

• A needle or catheter is placed in a vein.
• Blood is drawn into a special machine.
• The machine separates plasma from blood cells.
• The harmful plasma is removed.
• Blood cells are mixed with replacement fluid.
• The cleaned blood is returned to the body.

The entire process usually takes 2–3 hours per session. When people search for 'plasmapheresis' and 'plasma exchange’, they are usually referring to the same procedure. 'Plasma exchange' is the technical term for removing and replacing plasma.

Why Plasmapheresis Dialysis Is Used in Kidney Treatment

Now, let’s understand why plasmapheresis is done in kidney patients. Doctors recommend plasmapheresis dialysis when:

• The immune system is attacking the kidney tissues.
• There is rapidly progressing kidney inflammation.
• There are harmful antibodies in the blood.
• A patient is preparing for a certain kidney transplant.

In conditions like lupus nephritis, anti-GBM disease or certain types of vasculitis, plasmapheresis for kidney disease treatment may help control damage. Plasmapheresis for kidney disease helps by removing the harmful proteins that are damaging the kidneys.

When Is Plasmapheresis Dialysis Recommended?

Doctors may suggest that you get plasmapheresis dialysis in the following situations:

• If you have severe autoimmune kidney diseases
• Because of sudden kidney failure due to immune causes
• When the kidney is rejected after transplant because of antibodies
• Blood type–incompatible kidney transplant preparation

Doctors do not recommend this treatment for every kidney patient. It is usually recommended when medicines alone are not enough.

Potential Risks and Side Effects of Plasmapheresis

Like any medical treatment, plasmapheresis dialysis has possible side effects. Common risks include:

• Low blood pressure
• Dizziness
• Fatigue
• Allergic reactions to replacement plasma
• Risk of infection at the catheter site

Because plasma contains clotting factors, removing it may slightly increase the risk of bleeding. However, the procedure is done under strict medical supervision.

Advantages of Plasmapheresis in Kidney Care

Despite the risks, plasmapheresis dialysis offers important benefits:

• Quickly removes harmful antibodies
• Slows down immune-related kidney damage
• Supports transplant success in certain cases
• Can be combined with medicines for better results

In many cases of plasmapheresis kidney disease, early treatment improves outcomes.

Plasmapheresis Dialysis vs. Other Kidney Treatments

There are several treatments used in kidney care; it’s helpful to know where plasmapheresis fits in.

• Regular dialysis: Removes waste and excess fluid.
• Medications: Suppress the immune system.
• Plasmapheresis dialysis: Removes harmful antibodies directly.

Doctors may combine treatment options. For example, plasmapheresis for kidney disease is often used along with steroids or immunosuppressive medicines. So, if you wonder if plasmapheresis is enough on its own? It is usually part of a larger treatment plan.

Preparing for Plasmapheresis Dialysis

If you are scheduled for plasmapheresis, preparation may include:

• Getting your blood tested before the procedure
• You will have to check your blood pressure and heart health
• Informing the doctor about medications
• Stay hydrated

Patients often ask, 'How often is plasmapheresis done?’ It depends on the condition. Some may need daily sessions for a few days; others may need 2–3 sessions per week or a fixed number like 5–7 sessions monthly or weekly. The answer is that it depends on how severe the disease is and how the patient responds.

Future Prospects of Plasmapheresis Dialysis in Medicine

Medical science advances and so there is ongoing research to improve plasmapheresis:

• More efficient plasma separation machines
• Better replacement fluids
• Targeted antibody removal techniques

As knowledge grows, plasmapheresis dialysis may become safer and more precise, especially in complex immune-related kidney diseases

Conclusion

Plasmapheresis dialysis is a specialised treatment that removes harmful immune substances from the blood to protect the kidneys. It is not the same as regular dialysis but in certain kidney conditions, it can play a life-saving role.

If you or a loved one has been advised of this treatment, speak to a kidney specialist and understand your options. For expert kidney care and guidance, you can book an appointment with NephroPlus.

FAQs

What conditions make a patient eligible for plasmapheresis dialysis?

Patients with severe autoimmune kidney diseases, rapidly progressing glomerulonephritis, antibody-mediated transplant rejection or anti-GBM disease may be eligible. Doctors decide based on lab tests, biopsy results and the rate of worsening kidney function.

How often do patients undergo plasmapheresis dialysis?

The number of plasmapheresis dialysis sessions depends on the condition and stage of kidney disease. Some patients need daily sessions for 3–5 days, while others may need treatments several times a week. The schedule is personalized based on disease severity and response.

Can plasmapheresis dialysis be combined with other treatments?

Yes. It is commonly combined with steroids, immunosuppressive drugs or regular dialysis. The goal is to remove harmful antibodies while also stopping the immune system from producing more.

Is there any specific diet recommended for patients undergoing plasmapheresis dialysis?

There is no special diet only for plasmapheresis dialysis. However, patients with kidney disease may need to limit salt, potassium or protein depending on their condition. You should always ask your dietitian and follow a nephrologist’s dietary advice.

How do healthcare providers determine the number of necessary plasmapheresis sessions?

Doctors assess blood test results, antibody levels, kidney function and clinical symptoms. Improvement in lab values and patient condition helps the doctor determine whether you will need additional plasmapheresis sessions.
