PITTSBURGH, PA – A collaborative research effort has yielded a โขpotentially life-saving therapy for carbon monoxide (CO) poisoning, โa pervasiveโค threat to first responders and the public alike. Scientists at the University of Pittsburgh and the University ofโค Maryland School of Medicine have engineeredโค a novel treatment derived from a naturally โคoccurring protein,offering a significantly faster response than current methods.
Theโข Silent Threat of Carbon Monoxide
Carbon monoxide is a colorless, odorlessโ gas that interferes with the blood’s ability to carry oxygen. Worldwide, โtens of thousands succumb to CO poisoning annually, with millions more โขexperiencing non-fatal incidents. The insidious nature of CO stems from its abilityโค toโ bind to hemoglobin-the oxygen-carrying protein in red blood cells-with a far greater affinity than oxygen, leading to hypoxia โขand a range of symptoms from โheadaches and nausea to dizziness and ultimately, loss of consciousness.
Did You Know? Carbon monoxide poisoning is a leading cause of unintentional poisoning deathsโ inโ the United States, with approximately 430 deaths each year, according โto the Centers for Disease Controlโ andโ Prevention.
A Novel Approach: โRcoM-HBD-CCC
the newly developed therapy centers around aโ hemoprotein called RcoM-HBD-CCC, sourced from theโค bacterium Paraburkholderia xenovorans. This protein functions as a “sponge,” actively scavenging carbon monoxide from the bloodstream. researchers detail their findings in aโ recent publication in the Proceedings of the National Academy of Sciences (DOI: 10.1073/pnas.2501389122).

speeding Up Response Times
Current treatments for COโค poisoning primarily involve administering high-flow oxygen,sometimes โin hyperbaric chambers for severe cases. While effective, these โmethods are time-consuming, a critical โฃdrawback in emergency situations where every minute counts. The “golden hour”-and evenโค theโ “platinum ten minutes”-are crucial in trauma care, and conventional CO treatments can feelโค agonizingly slow.
In contrast, RcoM-HBD-CCC demonstratesโ remarkable speed. Studies indicate the protein canโ remove half of the carbon monoxide from the bloodstream in โunder a minute.Researchers discovered that RcoM-HBD-CCC binds to CO nearly 50 times faster than hemoglobin, initiating detoxification immediately upon entering the circulatory system.
Addressing a Key Challenge: Nitric Oxideโ Affinity
A significant โhurdle โคin developing CO antidotes has been finding a substance thatโข selectively targets carbon monoxide without interferingโฃ with nitric oxide. Nitric oxide is vital for โขregulating blood pressure, and disrupting its functionโ could lead to risky hypertension. โFortunately, intravenous administration ofโฃ RcoM-HBD-CCC in mice showed no hypertensive effects, a โcrucial finding for itsโ potential clinical request.
pro tip: Regular maintenance โof fuel-burning appliances, such as โfurnaces and water heaters, and the installation of carbon monoxide โฃdetectors are essential preventativeโค measures against COโข poisoning.
Looking Ahead: Clinical Trials โand Beyond
Timothy johnstone, a guest editor for the research โpaper and a researcher at theโ University of California, Santa Cruz, expressed optimism about the therapy’s future. “This โฃis aโ problem so uniquely suited to a โฃbioinorganic solution,” Johnstone stated. “Technical improvements like the one described here will only continue to bring the application closer to practical realization.”
Beyond its potential as an antidote, RcoM-HBD-CCC’s unique โproperties could pave the way for advancements in oxygen delivery systems, treatments for anemia and blood loss, and even organ preservation techniquesโข for transplantation.Researchers are now focused on โscaling up production and preparing for human clinical trials.

Carbon Monoxide Poisoning: A Persistent Public health Concern
Carbon monoxide poisoning remainsโค aโฃ significant public health issue, especially during colder months when heating systemsโ are in use. Awareness of the risks, proper ventilation, and the use of CO detectors are crucial for prevention. โฃ The development of RcoM-HBD-CCCโฃ represents a major step forward โคin emergency โmedical care,โ offering a fasterโข and more effective treatment option for a potentially deadly condition.
Frequently Asked Questions About Carbon Monoxide Poisoning โฃand New Treatments
- What is carbon monoxideโ poisoning? โCarbon monoxide poisoning occurs when CO gas builds upโข in โคyour โขbloodstream, replacing oxygen and leading to hypoxia.
- What are โขthe symptoms of CO poisoning? Symptoms range from headache, dizziness, and nausea to confusion, loss of consciousness, and ultimately, death.
- How is CO poisoning currently treated? โฃ Current treatment involves administering high-flow oxygen,โฃ sometimes in a hyperbaric chamber.
- How does rcom-HBD-CCC work? This protein acts as a “sponge,” rapidly scavenging carbon monoxide โขfrom the bloodstream.
- When will this new therapy beโฃ available? The therapy is currently in pre-clinical development and is expected to enter human โคclinical trials in 2026.
We hope this article has provided valuable insight into the groundbreakingโค research surrounding carbon monoxide poisoningโฃ and the potential for aโ new, life-saving therapy.
