Helping the Heart Stand Up to Sepsis

NIH Researcher Explores Why Some Survive Infection-Induced Organ Damage

“When you have eliminated the impossible, whatever remains, however improbable, must be the truth.” That line from Arthur Conan Doyle’s Sherlock Holmes can be applied to mysteries of all sorts, including the ones scientists toil away in their labs to solve. When it comes to solving the many mysteries of sepsis — a life-threatening immune over-reaction to an uncontrolled infection — the process of elimination is leading us closer to answers, thanks to researchers at the NIH Clinical Center.

Sepsis — also known as septic shock in its most severe form — occurs when the body’s immune system kicks into overdrive to fight a severe infection. Unfortunately, rather than just attacking the harmful invaders, the immune system releases chemicals that, when present in excess, cause intense, tissue-damaging inflammation and impair organ function. In recognition of Sepsis Survivors Week, we spoke with IRP Senior Investigator Charles Natanson, M.D., about two of the great mysteries of sepsis: how does sepsis cause organ failure in the first place, and why do some people survive it while so many others die?

Pandemic Brings All Hands on Deck

IRP Investigators Begin Hundreds of New Coronavirus-Related Studies

Within just a few months after COVID-19 began spreading in the United States, IRP researchers had already made numerous important contributions to the fight against the deadly virus. Scientific knowledge about the disease continues to expand at a unprecedented pace, and the IRP will continue to play a major role in this effort over the coming months and years. In fact, nearly 300 new intramural research projects related to the novel coronavirus are currently starting up or have already begun.
