Common OTC Supplement Helps 8-Year-Old Walk Again

• LEARN MORE: Physician cautions about five typical supplements that may lead to heart attacks

A substance found in a widely available dietary supplement has enabled an eight-year-old child to regain the power to walk, described as a "dream realized."

The young boy, whose name has not been disclosed, once ranked as the swiftest runner in his class and was passionate about playing football, often spending time engaging in matches with his peers.

However, in August 2023, he began having difficulty walking—and after three months, he was limping frequently, experiencing repeated falls, and required a wheelchair.

His parents took him immediately to medical professionals, who at NYU Langone determined he had a genetic condition called HPDL deficiency.

The illness is uncommon — having been documented in just 90 instances since its discovery in 2022 — and prevents the body from producing sufficient amounts of an enzyme known as coenzyme Q10 (CoQ10), which is essential for providing cellular energy.

Consuming CoQ10 supplements, which cost approximately 20 cents each and can be purchased without a prescription, may offer some benefits, yet they are insufficient to energize brain cells since the enzyme is too big to pass through the blood-brain barrier.

If there isn't sufficient amounts of the enzyme present in the brain, individuals experience difficulty walking or managing their muscle movements and face an increased likelihood of having seizures.

Therefore, instead of just providing the young boy with a supplement, his physicians stated: "We thought, why not supply the cell with the necessary components so that it can produce it on its own?"

The fundamental component of CoQ10 is known as 4-HB and is small enough to pass through the blood-brain barrier. Physicians managed to create a powdered form of it, which the child consumed mixed into a water-based solution.

His parents, speaking to STAT News under the condition of anonymity, he stated: "Our son's health underwent a significant change within a brief time frame."

He transitioned from being the quickest runner in his class and a passionate soccer enthusiast to having difficulty walking, frequently limping and suffering from regular accidents.

It was among the most difficult choices we have ever faced [to pursue the experimental therapy], yet taking no action seemed more dangerous. We witnessed how rapidly our son was deteriorating and understood that we needed to take action.

Following discussions with medical professionals and conducting our own investigations, we found encouragement and belief to face the uncertain.

Just one month after starting the therapy in November 2023, he was laughing and walking once more—completing almost a mile-long trek through Manhattan's Central Park.

He frequently participates in extended walks and physical activities and has marked two birthdays since then.

The matter came to light in the publication Nature with experts now expressing their desire for it to assist others.

HPDL deficiency develops if an individual receives two altered forms of the the human 4-hydroxyphenylpyruvate dioxygenase-like (HPDL) gene, responsible for producing the CoQ10 enzyme.

In certain instances, the illness is extremely serious and manifests at a young age, leading to substantial intellectual development issues and convulsions. According to scientists, individuals affected frequently do not survive past their first eighteen months.

However, it may also affect children during later phases of childhood and teenage years, causing physically fit kids to experience leg muscle weakness and tightness.

Medical professionals have associated this condition with unusual activity in the cerebral cortex—the brain's outer layer—which plays a role in thinking and controlling body movements.

In this instance, the child apparently showed no symptoms until reaching the age of eight—despite medical professionals suggesting there may have been early indicators.

A young boy first began taking CoQ10 supplements, but after consultation with medical professionals, his family was advised to attempt 4-HB — a substance that has not received approval from the FDA.

He stopped using the supplements thereafter.

For the initial 30 days, he consumed the supplement mixed with 600ml of liquid, roughly similar to three cups of water, which frequently caused him to vomit afterwards.

It was subsequently diluted to a 300ml solution, slightly more than one glass of water.

The U.S. Food and Drug Administration has not authorized CoQ10 or 4-HB for use in treating any particular illness or health issue, even though CoQ10 can be purchased without a prescription.

The product is frequently advised to enhance vitality and combat sensations of tiredness.

Medical professionals suggest it may offer assistance to individuals suffering from ailments such as congestive heart failure and headaches.

In a 2021 experiment, 4-HB was evaluated on mice suffering from HPDL deficiency, where scientists observed that it helped restore their walking capability. Administering it to an eight-year-old marked the initial application of this treatment for such a condition in human patients.

"CoQ10 is considered safe. It shows moderate effectiveness in addressing symptoms located outside the brain, yet it is nearly useless for treating conditions inside the brain since it cannot cross the blood-brain barrier," said Michael Pacold, an associate professor of radiation oncology at NYU Langone and co-author of the study, according to STAT.

The proposal to utilize the 4-HB construction kit with the young boy received approval from the parents, the child himself, and the FDA—which permitted its usage as an individualized experimental medication, allowing physicians to administer an untested drug or compound to a particular patient for treating a distinct medical issue.

Owing to its achievements, researchers are referring to it as a significant advancement in healthcare.

"We all aspire to this as researchers. Each morning, I check myself ... is this truly just a fantasy?" stated Pacold.

Dr. Navdeep Chandel, an authority in medicine from Northwestern University who did not participate in the study, remarked: "This represents fundamental scientific findings making their way into practical medical applications—a long-held aspiration."

But here's someone who used a fundamental biochemical method, identified the enzyme, determined its function, and administered the enzyme to individuals with genetic mutations. It led to an improvement.

Currently, Pacold and his group are conducting an expanded research project to evaluate this method with additional children.

He said: "It requires not only the discovery, but also individuals ready to embrace the risk."
