An article published in Frontiers in Immunology suggests that sepsis can cause alterations in the functioning of defense cells that persist even after the patient is discharged from hospital. This cellular reprogramming creates a disorder the authors call post-sepsis syndrome, whose symptoms include frequent reinfections, cardiovascular alterations, cognitive disabilities, declining physical functions, and poor quality of life. The phenomenon explains why so many patients who survive sepsis die sooner after hospital discharge than patients with other diseases or suffer from post-sepsis syndrome, immunosuppression and chronic inflammation.
