New treatment approaches for acute chest syndrome in sickle cell disease

Therapeutic Targets in Acute Chest Syndrome

NIH-funded research Emory University · NIH-11343275

What this research studies

If you have sickle cell disease and get acute chest syndrome (ACS), this project studies a natural protein called heme oxygenase-1 (HO-1) that helps clear toxic heme from the blood. Researchers observed that children have higher HO-1 levels and that giving extra HO-1 improved survival in adult mice with ACS, so they will measure HO-1 in blood and study how HO-1 is regulated in people with SCD. The team will also test a lab-made (recombinant) HO-1 treatment in preclinical models to see if it reduces lung injury and improves survival. The aim is to find out whether replacing or boosting HO-1 could become a new molecular therapy for ACS.

Who could benefit from this research

Good fit: Ideal candidates are people with sickle cell disease who have had or are at high risk for acute chest syndrome and who can provide blood samples or join clinical follow-up.

Not a fit: People without sickle cell disease or with lung problems not caused by acute chest syndrome are unlikely to benefit from this specific approach.

Why it matters

Potential benefit: If successful, this work could lead to a new therapy that prevents or reduces life-threatening lung injury during ACS in people with sickle cell disease.

How similar studies have performed: Prior animal studies showed that supplementing HO-1 improved survival in mice with ACS, but using recombinant HO-1 in humans is novel and has not yet been tested clinically.
