VIDEO: Hero grandmother donates kidney to Doncaster toddler

Even before Jack Cox was born, his family knew they were extremely unlikely to be able to bring a healthy baby into the world when early scans showed signs of severe kidney problems.

Parents Jennifer and Steven hoped for the best, and little Jack was born six weeks early missing one kidney, and with only four per cent function in the other.

The adorable youngster spent his first two months of life in hospital while medics tried to determine the extent of damage caused to his organs.

After his proud parents were finally able to bring him back to their Tickhill home, Jack spent his first two years of life in constant agony vomiting 30-40 times a day and being fed by a tube into his stomach.

Jack’s grandmother Julie Cox, or ‘nanan’ as Jack calls her, says she knew from the moment he was born that she was ‘destined’ to donate one of her kidneys to him.

The 59-year-old said: “I just knew it would be me, don’t ask me why but I just had this feeling.

“I even started getting ready to save holiday so I could book time off work because I knew it.

“The surgeons told me this happens more than you think - there’s just something in the genes that tells you.”

Last Autumn when Jack’s kidney began to fail and he was put onto dialysis at the age of just two, most of Jack’s family began to get tested to see if they were a match.

Only Julie and Jack’s dad Steven were found to share the same rare blood type, B positive. and so they were put forward to the next stage for tissue testing.

Each person is born with three sets of unique genetic markers known as antigens from each parent.

When looking for kidney donor parents are often the best person to receive the organ from because they share at least three antigens out of six with you, and identical twins are even better because they share six out of six.

When Julie was tested, she was found to miraculously share five out of the six sets of unique genetic markers with Jack.

The grandmother-of-seven said: “It was the best match we could have hoped for. The doctors don’t even understand it how it’s possible for me to share that many of sets of genes with him.

“Doctors are often concerned about children receiving adult kidneys, but when they looked at my left kidney it was only two thirds the size of a normal adult kidney but it was doing 45 per cent of the work so was fine.

“And my ureter, which is one of the parts Jack was born without, was longer than normal so it meant it was easier to attach my kidney. I feel like I was born to donate a kidney to Jack.”

And in May this year, after months of testing and waiting for a spot with the surgeon Julie was finally able to donate to her kidney to Jack.

Thinking back to the night before the transplant operation, Julie says she did not even consider the risks to her health.

She said: “They test to make sure you’re fit and healthy before you’re very far into this process, but I didn’t even think about my age or anything like that I was so determined to be able to give him my kidney. I wasn’t scared before the operation, again because of that determination.”

After some initial medical issues for both Jack and Julie, the kidney transplant was successful.

Four months on and Julie says the transformation in Jack has been ‘miraculous’.

She said: “It’s been unbelievable. Because he was vomiting so much before Jack had a muslin cloth over his mouth most of the time, and so even though he could talk he didn’t much. He also couldn’t stand for long periods of time because he was in so much pain. But now he’s just got so much energy and is running about all the time. He’s like any normal three-year-old now, which is something a lot of the family never thought they’d see. When he was born his parents were told to go home and expect the worse, and so for two years every time the phone rang we expected the worst.

“When his aunties and uncles see him now they just burst into tears, because of how bad things were before. In the back of my mind though I always knew that I’d be able to give him a transplant and that he’d make it.”

There is a 56 year age gap between Julie and Jack - which is one of the largest ever recorded in the UK.

While Jack’s life is finally beginning to resemble that of any normal toddler, he will need to take immunosuppressants in order to prevent his body from rejecting his kidney for the rest of his life and may even need another transplant one day.

Because of the thousands of children just like Jack in need of a kidney, Julie is now encouraging more people to sign up to become an organ donor.

She said: “I was a live donor and it didn’t hurt me, so it’s not going to hurt you when you’re dead!

“We’re living longer now, but the number of organs being donated is going down.

“There are hundreds of parents and grandparents out there who love their sons and grandsons just as much as we love Jack, but they might not have the same outcome we’ve had because of this which is just heartbreaking to think about.”
