Three individuals who traveled to Mexico for stem-cell injections that aren’t accredited within the U.S. contracted difficult-to-treat, drug-resistant infections, a Morbidity and Mortality Weekly Report (MMWR) from the Facilities for Illness Management and Prevention warned Thursday (Might 9).
The infections had been brought on by Mycobacterium abscessus, a bacterium that is distantly associated to those behind tuberculosis and leprosy. The microbe generally lurks in soil, water and dirt, and it is identified to typically contaminate medicines and medical gadgets and thus trigger infections in well being care settings.
Signs can embrace boils and pus-filled bubbles, within the case of pores and skin infections, in addition to fever, chills and muscle aches, when soft-tissue infections happen. Typically, the micro organism can invade the bloodstream. Treating the an infection includes eradicating contaminated tissues and draining pus from the physique, in addition to giving antibiotics for a protracted interval.
For a given affected person, docs might have to check totally different medication towards samples of micro organism from their physique, in an effort to discover probably the most deadly mixture towards the drug-resistant bug.
All three sufferers who bought stem-cell injections in Mexico underwent the procedures in 2022, and as of March 2024, they had been nonetheless being handled for M. abscessus an infection in U.S. hospitals, in keeping with the MMWR.
Associated: Harmful ‘superbugs’ are a rising menace, and antibiotics cannot cease their rise. What can?
“Suppliers and public well being businesses want to pay attention to the chance for M. abscessus infections from stem cell remedies for indications not accredited by the Meals and Drug Administration and preserve vigilance for comparable instances,” the report’s authors wrote. “In addition they are suggested to supply steering for individuals contemplating medical tourism.”
The solely stem-cell merchandise presently accredited within the U.S. comprise precursors to totally different cells within the blood, and so they’re cleared to deal with problems that have an effect on the manufacturing of blood.
The primary of the three instances concerned a Colorado girl in her 30s, who in October 2022 had traveled to Baja California to get stem-cell injections within the tissues that encompass the mind and spinal wire.
The injections had been reportedly meant to deal with the autoimmune illness a number of sclerosis, for which there are not any accredited stem-cell remedies within the U.S. After the injections, she developed complications and fever, and at a hospital within the U.S., the fluid round her mind and spinal wire examined optimistic for M. abscessus. This indicated she had a critical an infection known as bacterial meningitis.
Two comparable instances concerned males of their 60s — one from Arizona and one from Colorado. The Arizona man had developed an an infection in his elbow after touring to Baja California for therapy of psoriatic arthritis. He was handled at a special clinic than the Colorado girl was, and the clinics had been 167 miles (269 kilometers) aside.
The Colorado man, in the meantime, had traveled to Guadalajara, Mexico, for therapy of osteoarthritis in his knees after which developed infections in each knees. The usage of stem-cell injections for a number of sclerosis and arthritis are unproven, as potential stem-cell therapies for these situations are nonetheless being investigated.
Whereas treating the sufferers, a U.S. hospital obtained samples of the M. abscessus micro organism from the Colorado girl and Arizona man; samples from the Colorado man nonetheless have to be intently assessed, however they have been confirmed to be M. abscessus.
Genetic analyses revealed that the 2 sufferers’ samples had been a near-perfect match. Subsequently, the investigators “suspect a standard contaminated supply” for these two sufferers, which means the identical merchandise or tools might have been contaminated in each instances.
Nevertheless, authorities “tried to contact clinics that carried out the stem cell injections, however obtained no response,” the MMWR notes, and “makes an attempt to determine the product or collect particulars about its administration have been unsuccessful so far.” Authorities within the U.S. and Mexico are persevering with to analyze the three identified instances and are in search of extra ones.
Medical tourism has been tied to M. abscessus infections previously. For instance, a Canadian man who underwent a hair transplant in Panama developed such an an infection on his scalp. So these superbug infections can come up after each beauty procedures and therapies meant to deal with illness.
