TB Hides In Bone Marrow
Michelle Fay Cortez writing in Bloomberg News reported on a study in “Science Translational Medicine. Researchers said they have uncovered the first evidence of tuberculosis hiding in mesenchymal stem cells in the bone marrow of people treated for the disease.”
According to the article, “the bacteria’s hideout in the self-renewing cells, where they capitalize on protection from the body’s own immune system, may explain how the germs survive.”
This is disturbing news since these sequestered tuberculosis bacteria can be protected from drugs used to eradicate them.
This has important implications for patients intending to go on biologic therapy for rheumatoid arthritis and other diseases.
