Stem Cell Clinics

Recent practices at “stem cell clinics” in the United States have resulted in blinding complications for three patients who underwent bilateral intravitreal injection of adipose-derived stem cell injections for dry age-related macular degeneration, as recently published in the New England Journal of Medicine: patient’s vision went from 20/30 to no light perception and 20/200.

The “stem cell clinics” problem is that they provide unproven, unregulated, and costly ($50,000) treatment for a variety of disorders and raise high concern for patients.

By having studies listed on clinicaltrials.gov, “stem cell clinics” seemingly bolster their legitimacy to patients. clinicaltrials.gov website is simply a repository of clinical studies and does not judge the merits of the listed studies.

It is important to encourage patients to speak with a “trusted healthcare professional” prior to enrolling in a study. Exploring the difference between the positive stem cell research and the activities carried out at “stem cell clinics” is essential in preventing such catastrophic outcomes.

Further regulation of these “stem cell clinics” is also necessary to help prevent similar outcomes in the future.
