Girl, 8, becomes first UK transplant patient not to need life-long drugs

A UK-first procedure means Aditi Shankar’s body accepts her new kidney as its own, following pioneering work by doctors at London’s Great Ormond Street Hospital.

Girl receives ”rejection free’ kidney from mum

An eight-year-old girl has become the first person in the UK to have a transplant – and not need to take immunosuppressant drugs for the rest of her life.

Aditi Shankar, who has a rare genetic condition, has received both a new kidney and bone marrow from her mother, Divya.

Because she had a stem cell transplant, via the bone marrow, she was able to come off immunosuppressants a month after receiving the new organ.

Following pioneering work by doctors at London’s Great Ormond Street Hospital (GOSH), her body has accepted the new kidney as its own.

Immunosuppressants are an important part of most transplant patients’ lives, because they stop the body from rejecting a donated organ.

But while they provide a vital function, they work by dampening down the body’s immune system.

Anyone taking them is therefore at higher risk of infection, among other complications.

Aditi was referred to GOSH when she was five and doctors discovered she had a condition called Schimke’s immuno-osseous dysplasia, which impacts the immune system and kidneys.

In the UK, it affects about one child in every three million.
Aditi’s underlying immune condition initially meant she would “not be able to receive a kidney transplant”, said Professor Stephen Marks, children’s kidney specialist at GOSH.

But working with international colleagues, the renal, immunology and stem cell transplant teams at GOSH came up with a treatment plan.

Prof Marks added: “Her immune deficiency had to be corrected by having her mum’s bone marrow first, and because Aditi was able to accept her mum’s bone marrow, that therefore meant her body could then see her mum’s kidney as being part of her.

Elon Musk’s Neuralink looking for people to trial its brain-computer chip

Tesla and X CEO Elon Musk’s neurotechnology company Neuralink has revealed it is looking for people to trial its brain-computer chip, despite fierce criticism of its ‘deadly’ animal tests.

The company got the green light from an independent review board to start their brain-computer interface testing on people suffering from paralysis from from cervical spinal cord injuries or amyotrophic lateral sclerosis (ALS). Musk has previously claimed that his BCI “will enable someone with paralysis to use a smartphone with their mind faster than someone using thumbs.”

He and his company will now initiate recruitment for the first human trial of its brain implant, but neither stated the number of participants to be enrolled in the trial, which is expected to span approximately six years. During the study, a robot will implant the chip in a brain region responsible for the intention to move. Musk’s aim is for the person’s thoughts to control a computer cursor or keyboard.

Hope for artificial kidney as scientists announce first successful animal tests with implantable device

A Bangladesh-born bioengineer and his colleagues at the University of California, San Francisco, have shown that kidney cells in an implantable device survived in a pig for seven days, mimicking several key kidney functions

Scientists on Tuesday announced the first successful animal tests with an implantable device that represents a key step towards an artificial kidney that could someday eliminate the need for dialysis in patients with kidney failure.

A Bangladesh-born bioengineer and his colleagues at the University of California, San Francisco, have shown that kidney cells in an implantable device survived in a pig for seven days, mimicking several key kidney functions.

The scientists say their study provides the “first proof of concept” of an implantable bioreactor that sustains human kidney cells in a pig model without being attacked by the recipient’s immune system.

After implantation into pigs, the cells maintained over 90 per cent viability and functionality, the researchers said, describing their work in a paper published on Tuesday in the research journal Nature Communications.

“We are focused on safely replicating the key functions of a kidney,” Shuvo Roy, a professor of bioengineering at the UCSF School of Pharmacy, said in a media release issued by the university. “The bioartificial kidney will make treatment for kidney disease more effective and much more tolerable and comfortable,” said Roy. Their goal is to develop a bioreactor with kidney cells that perform critical functions — such as balancing the body’s fluids and releasing hormones that help regulate blood pressure — and pair it with a device that filters waste from the blood.

Current treatment options for kidney failure include dialysis and transplants. But not enough organs are available for transplants and, the scientists say, dialysis partially replaces kidney cell functions and most dialysis patients develop long-term complications.
