In 30 cancer patients, a blood treatment calmed severe immune reactions caused by cancer drugs.
A blood filtering treatment helped cancer patients whose immune systems attacked their own bodies after cancer drugs. The treatment is called photopheresis. In a trial of 30 patients, it was safe and worked for 96% of people with these harmful immune reactions. Patients also showed lower levels of inflammation markers in their blood and gut tissue.
The share of patients whose severe immune side effects improved after the blood treatment.
Small trial of 30 patients, no control group yet.
