Three Patients Who Received Embryonic Stem Cell Injections In Mexico Developed Difficult-To-Treat Mycobacterium Abscessus Infections, Study Finds

MedPage Today (5/9, Putka) says, “Three patients developed difficult-to-treat Mycobacterium abscessus infections after receiving embryonic stem cell injections in Mexico in 2022, researchers reported.” Two men “acquired the infections in Guadalajara and Baja California, Mexico, from donor embryonic stem cell injections for joint pain, reported” researchers in the Morbidity and Mortality Weekly Report. Previously, a third patient “had received intrathecal donor embryonic stem cell injections, also in Baja California, to treat her multiple sclerosis and also contracted an M. abscessus infection.”
