Treatment For Rare Neonatal Disease Found

An international team of physicians has found a treatment for molybdenum cofactor deficiency Type-A, a rare neonatal disease.

AsianScientist (Sep. 15, 2015) – In a study published in The Lancet, scientists describe a treatment for molybdenum cofactor deficiency Type-A, a congenital disease considered to be universally fatal.

“We don’t use the word cure very often in medicine, but this research shows that under the right circumstances this is a cure,” Dr. Flora Wong, a Monash Health neonatologist and researcher with Monash University and the Hudson Institute of Medical Research, said.

Wong was part of a global research project team that has shown this disease that had no hopes for survival can now be treated effectively.

“We now know that early and careful treatment of babies born with this rare condition can lead to survival with good long-term developmental outcomes,” Wong explained.

In 2009, Monash Health made medical and legal history by curing ‘Baby Z’, who was the first baby to ever survive molybdenum cofactor deficiency Type-A, a previously incurable disease that had no prospects of survival. Babies born with the disease did not survive past early infancy.

Molybdenum cofactor deficiency Type-A is a rare condition that causes toxic sulphites to rapidly accumulate in the brain of newborns, causing seizures and the death of brain tissue, leading to death.

After Baby Z’s diagnosis with the illness, Monash Health neonatologists led by Dr. Alex Veldman identified a possible treatment, cPMP (cyclic pyranopterin monophosphate). It had never before been used in humans and required unprecedented and fast-tracked legal approvals before being administered.

The treatment rapidly improved Baby Z’s sulphite (S-sulfocysteine) levels. Although she has experienced ongoing health issues, the innovative treatment allowed her to become the first human to ever survive the condition. (Please note that Baby Z’s identity remains undisclosed for legal reasons.)

Data showed that S-sulfocysteine levels rapidly improve once treatment commences. The new research published has shown that the compound is even more effective than previously thought. With earlier administration of the treatment before brain injury ensues, we have seen babies survive this illness with no significant complications whatsoever.

“Because this is a rare condition we took a global approach, and treated 11 babies affected by molybdenum cofactor deficiency Type-A from around the world with the compound. It was safe, and we’ve shown that early treatment can be amazingly effective over a long time,” Wong added.
