HSCT – Life Changing Treatment for Chronic Inflammatory Demyelinating Polyneuropathy (CIDP)

CIDP is a serious autoimmune condition — one that slowly chips away at the nerves and, without the right treatment, can significantly change the way you live. But for many patients, Hematopoietic Stem Cell Transplantation (HSCT) is opening a door that once felt firmly closed.

At HSCT Hospital India, a JCI-USA accredited centre, we’ve helped patients from Europe, North America, and Australia get their lives back through HSCT treatment that is both world-class and carefully matched to each individual.

What Is CIDP?

HSCT is not only for CIDP. We also treat multiple sclerosis, lupus (SLE), myasthenia gravis and NMOSD with the same autologous stem cell transplant.

Your immune system is supposed to protect you. In CIDP, it turns on you instead — specifically, on the myelin sheath, the protective coating that wraps around your peripheral nerve fibres. When that coating gets damaged, nerve signals slow down or stop getting through altogether. The result is weakness, numbness, and a loss of coordination that tends to creep up gradually rather than arriving all at once.

CIDP isn’t a short-term problem. Symptoms usually develop over eight weeks or longer, and they can stick around for months or even years. It’s more common in men than women, and while it can happen at any age, most people are diagnosed in their 50s or 60s. Typically, symptoms start in the feet, then work their way up the legs and arms — and they usually affect both sides of the body at the same time.

What Are the Symptoms of CIDP?

CIDP can look different from one person to the next, but the most common symptoms are:

• Progressive weakness in the arms and legs
• Tingling or burning sensations, particularly in the hands and feet
• Numbness and reduced sensation
• Problems with balance and coordination
• Persistent fatigue
• Changes in voice or slurred speech (in some cases)
• Partial or complete paralysis (in severe cases)

For some people, the decline is slow and steady. For others, symptoms come in waves — flaring up and then partially settling down again.

What Triggers CIDP?

• Honestly, in many cases, there’s no clear answer. No single cause has been identified, and for a lot of patients, CIDP seems to appear without an obvious reason.
• That said, it does tend to show up more often alongside certain other conditions, such as:
• Diabetes
• HIV/AIDS
• Chronic hepatitis
• Inflammatory bowel disease
• Lymphoma or other immune-related cancers
• An overactive thyroid
• Side effects from medications used to treat cancer or HIV
• Even when an associated condition is present, the primary problem — and the primary target of treatment — is always the malfunctioning immune system itself.

Is CIDP Progressive? Will It Get Worse?

If left untreated or not properly managed, yes — CIDP does tend to get worse. The immune system keeps attacking the nerve fibres, and over time, that damage adds up.

How the disease progresses isn’t the same for everyone. There are generally three patterns, shown below:

Because no one can predict which pattern a given patient will follow — and because some of the damage can become permanent — acting early really does matter.

What Are the Stages of CIDP?

Unlike some cancers, CIDP doesn’t have a formal numbered staging system. But doctors generally talk about severity in terms of how much the disease is affecting daily life:

• Early stage: Mild weakness, tingling, or sensory changes. Most daily activities are still manageable.
• Moderate stage: Weakness becomes more noticeable, balance starts to go, grip strength reduces. Getting through the day takes more effort.
• Advanced stage: Significant weakness or paralysis, loss of reflexes, and a major impact on independence. At this point, quality of life is seriously affected.

The earlier treatment starts, the better the chances of limiting long-term damage. Waiting rarely helps.

Is CIDP the Same as MS?

They’re related in the sense that both are autoimmune diseases that damage myelin, but they’re not the same condition.

If there’s any uncertainty about whether your diagnosis is CIDP or MS, getting a thorough neurological evaluation is essential — the distinction matters significantly when it comes to planning treatment.

What Happens If CIDP Goes Untreated?

The short answer: things get worse, and some of that damage doesn’t reverse. Untreated CIDP can lead to:

• Permanent numbness and loss of sensation
• Progressive muscle weakness and wasting
• Serious balance problems and a higher risk of falls
• Paralysis of the limbs
• Breathing complications in severe cases
• A significantly shorter, harder life

The immune system won’t stop attacking on its own. Every month without treatment is another month of damage accumulating — which is why getting assessed as early as possible makes such a difference.

Standard CIDP Treatments

Most patients start with one or more of the established first-line therapies:

• Corticosteroids (such as prednisone): Dampen inflammation and slow the immune attack on the nerves
• Intravenous Immunoglobulin (IVIg): Helps regulate the immune response; typically given as regular infusions
• Plasmapheresis (plasma exchange): A procedure that filters damaging antibodies out of the blood

These treatments work well for many people — but they’re not a cure. A significant number of patients need to keep coming back for treatment year after year, and some eventually find that these therapies stop working as well as they once did. For those patients, it’s worth having a serious conversation about HSCT.

Can HSCT Treat CIDP?

Yes — and for patients who haven’t responded well to conventional treatment, it can be genuinely life-changing.

HSCT doesn’t just put a lid on the immune system for a while. It resets it. The process eliminates the immune cells that have been attacking the myelin sheath and replaces them with healthy stem cells, giving the body a chance to build an immune system that behaves the way it’s supposed to.

Most patients who go through HSCT for CIDP see meaningful improvement or stabilisation in their symptoms — and many don’t need any further immunotherapy afterwards.

Here is what that improvement commonly looks like across the symptoms patients describe most often before and after treatment:

How Does HSCT Work for CIDP?

The treatment happens in four stages, and the whole process takes around 30 days in hospital:

1. Mobilisation — Medication is given to prompt the bone marrow to produce extra haematopoietic stem cells and release them into the bloodstream.
2.  Harvest (Leukapheresis) — The stem cells are collected from the blood using a specialised procedure and stored until they’re needed.
3. Conditioning — A targeted chemotherapy regimen is used to clear out the faulty immune system — essentially making room for the new one to take hold.
4. Reinfusion — The patient’s own stored stem cells are reinfused. They travel to the bone marrow and get to work building a fresh immune system — one that, crucially, doesn’t recognise the peripheral nerves as a threat.

Who Is a Candidate for HSCT?

HSCT isn’t the right fit for every CIDP patient, and we’d never suggest it was. Eligibility is assessed carefully, and the decision is always made with patient safety at the centre. The key factors we look at include:

• A confirmed CIDP diagnosis
• Insufficient response to first-line treatments
• How active the disease is and how quickly it’s progressing
• Overall health, including heart, lung, and kidney function
• Age and general fitness
