“We have started stem cell treatment for Nick and that just finished. We decided on this a couple of days ago,” Kloots said in her latest Instagram update on Cordero’s health.

Cordero, 41, has been hospitalized since April at Cedars-Sinai Medical Center in LA with COVID-19 symptoms. His leg was amputated due to complications of the virus, and he has struggled with a lingering lung infection.

Kloots, a 38-year-old fitness trainer, said Thursday there are “no guarantees” the treatment works, but they hope it will “help repair, help strengthen Nick’s lungs and get him better. So finger’s crossed. That’s the news.”

She also asked her followers for advice on medical treatments that could aid “the release of carbon dioxide from the lungs.

“If you think you know of a doctor or trial to help ONLY THAT please reach out to me. Real medically based information from credited sources please!”
