All You Need to Know about a Swap Donor Kidney Transplant (Paired Exchange Kidney Donation )

Ever wondered what would happen if your loved one needs a transplant and you are not a compatible match? What next? What could be done?

A swap donor kidney transplant is the answer. Also known as paired exchange kidney donation is an innovative method that helps thousands of patients in India.

Despite incompatible donors, patients have hope for better success and lifestyle with a paired exchange kidney transplant.

NU Hospitals Bangalore (Bengaluru) has top-notch transplant programs, advanced technology, experienced transplant physicians, and surgeons backed by exceptional care.

Read on as we explain how a swap donor transplant works, who qualifies, the cost of the transplant, and its benefits.

What is a Swap Donor Kidney Transplant?

A swap donor kidney transplant (paired kidney exchange) is an arrangement between two or more recipient-donor pairs who are incompatible with each other. This arrangement, where they exchange the donors, so all the patients (recipients) are known as a swap donor transplant. 

Now all patients receive compatible kidneys for the transplant.

Example:

There are two patients - A and B, their donors being C and D, respectively.

Now, Donor C is incompatible with A but matches B, and D is compatible with A.

The Donors are now swapped. Patient A gets the kidney from D, and Patient B gets from C.

This process can happen between two, three, or more patient-donor pairs. This is known as a domino or chain exchange.

How does a Kidney Swap Transplant Work?

A swap donation requires meticulous coordination medically, legally, and ethically.

Here is a step-by-step process on how it works:

1. Patient-Donor Evaluation

Every patient-donor pair will undergo standard evaluation for a kidney transplant. This includes

• Blood group matching

• HLA typing

• Crossmatch tests

• Health screening

• Additional tests as prescribed by the doctors

2. Finding a Compatible Match

If the patient-donor pair is found incompatible, they will be registered in a kidney swap registry by the transplant centre. This is a database of other incompatible pairs.

3. Matching with Another Pair

The registry finds a pair where the donors can be swapped. (This is completely run by algorithms to ensure a transparent and unbiased match)

4. Legal and Ethical Clearance

As this involves exchanging organs between unrelated individuals, a strict adherence to be followed with Transplantation of Human Organs Act (THOA), 1994. Additionally, an approval from the authorization committee is required in India.

5. Simultaneous Surgery

All transplants are done simultaneously, ensuring fairness and medical success. This helps in preventing last-minute withdrawals.

Who is Suitable for a Swap Donor Kidney Transplant?

Paired exchange kidney transplants are ideal for:

• Donor-recipient pairs with blood group or HLA incompatibility (Donor is B+ but recipient is O+)

• Donor-recipient pairs with positive crossmatch results and high antibody levels. They are also known as sensitized patients (patients with a highly reactive immune system, specifically towards HLAs). This makes it difficult to find a compatible donor. (sensitization might be due to prior exposures like pregnancy, blood transfusions, or previous transplants)

• Recipients wishing to avoid long waiting times for deceased donors.

Note: Both donor and recipient of each pair must be willing to swap transplants, be healthy, and meet transplant eligibility criteria.

Cost of a Swap Donor Kidney Transplant in India

The cost of a swap donor kidney transplant in India depends on various factors, like city, hospital, technology, and complexity of the match.

The approximate cost breakdown of a paired exchange:

The average cost includes surgery cost, pre-transplant evaluation, donor evaluation, hospitalisation, and medications. 

Swap transplant is expensive and more predictable than desensitization therapy for incompatible transplants.

Advantages of a Swap Donor Kidney Transplant

• Better Matching

There are better chances of finding a compatible kidney with a close immunological match. This helps with reduced rejection risk. Better matching provides better medical outcomes.

• Avoids desensitisation

Paired donation helps patients avoid expensive therapy for desensitisation.

• More lives saved

This helps in utilising available donors for more transplants

• Short waiting time

The waiting time is shorter compared to a deceased donor transplant, where patients have to wait for years.

• Transparent

The transplants are always approved and overseen by the indian government and THOA.

Is a Swap Transplant Common in India?

Swap transplants are quite common in India. 

According to the Indian Society of Organ Transplantation, more than 500 swap transplants were conducted in India between 2015 and 2023.

NU Hospitals Bengaluru (Bangalore) has a well-established paired kidney exchange program.

New technologies in registries and government databases have improved pairing speed and accuracy.

Is a Swap Transplant Safe?

Swap transplants are living donor transplants, and their outcomes and risks are similar.

Success rates:

• 1-year graft survival is 90-95%

• 5-year graft survival is 80-90%

• Donor risk is very low with minimally invasive nephrectomy

Both donor and recipient pairs are thoroughly evaluated to ensure safety.
