This is good news that Dr. Grekos is making future plans. I hope that they will also include membership in ICMS.

Stem-Cell Therapy
My Illegal Heart
Men's Health

Facing death inspires desperate measures. Like having your stem cells drawn in Florida, sent to Israel for processing, and shot into your ailing heart in the Dominican Republic. How far would you go to save your own life?
By: Mark Cohen,

Dr. Grekos says he has already begun planning for the day when stem-cell therapy becomes available in the United States, and he is working on a two-pronged strategy: moving treatment for any approved uses to his cardiology practice in Naples, and continuing to use unapproved treatments off shore. He says he just gained approval to treat patients in Freeport, in the Bahamas.

Recognizing that little can be done to stop the off shore clinics, and in an effort to review those clinics' claims, a group of scientists and doctors recently teamed up to create the International Cellular Medicine Society (ICMS). At this online registry, off shore clinics have patient results tracked and verified by an objective third-party source. But of 20 off-shore clinics contacted for a survey, only 11 responded, and only one met the criteria used by the ICMS to ascertain safety: TheraVitae. The report concluded that the most troubling aspect about the stem-cell clinics was a lack of transparency: "Nearly all the evaluated clinics refused to answer all questions posed."

Regenocyte did not participate because the survey was only for companies that process their own stem cells. But Regenocyte is not sharing its results with the ICMS. "When I first talked to Dr. Grekos last summer, he seemed interested," says Christopher Centeno, M.D., the Denver pain-management specialist and ICMS member who founded Regenerative Sciences. "Then he had me talk to his business manager, who later got back to me and said they'd decided not to participate. The way he put it to me was, he just didn't see what's in it for them." By joining such a registry, Regenocyte would be opening up its treatments to the same statistical metrics used by clinical trials. Patients who failed to respond as favorably would be lumped in with the star performers who achieved 10-minute gains in their treadmill times. The focus of prospective patients could start to shift from the anecdotal evidence that now dominates the company's marketing to the law-of-averages bottom line.

Ron O'Leary answers the phone. He sounds out of breath. "Hey . . . How are you doing?" he says, his voice ragged and halting. "Sorry," he goes on. "I just got in from a bike ride." It's been 6 months since his stem-cell procedure and O'Leary, now 37, sounds to be settling back into his old routine. That is, his old old routine, the one he had before a freak-of-nature heart malady reduced him to puttering around like a geriatric.

A few weeks earlier, O'Leary traveled to Naples for his 6-month follow-up. His ejection fraction had increased to 44, which was 14 points above where it was before the doctors repaired parts of his heart. He didn't experience the 21-point jump that Dr. Grekos says is typical, but 14 points is a significant improvement.

For O'Leary, though, the most telling test may have been one he administered to himself a week before his office visit. He'd ventured out onto a local bike trail for a 20-mile ride with two friends. "It's not like I was racing Lance Armstrong; these guys are in their 50s," he says. "On the way back I took off for a stretch. I left them behind. That's when I knew. I feel like there's nothing I can't do."

I am happy to hear that Dr. Grekos will be doing those stem cell treatments that are currently allowed. Having looked at the stem cell issue in depth before I had my procedure done in Santo Domingo and had contact with other Regenocyte patients who had been through the process at Santo Domingo. I liked what Dr. Grekos and Regneocyte offered. Although I am not by any means back to "normal", I am able able to lead a much more qualitative life. I am able to do five miles every other day on my Recumbent bike something that was out of the question previously where I could hardly breathe. My Ejection Fraction went from 20 to 35 after six months. I was told that it would never go beyond the 20 mark by my regular cardiologist. I don't know what my condition will be three months from now but I am very happy not only with the results but with the Regenocyte process. Much time and effort is given to determine "base line" readings before your stem cell procedure. The follow up at the three and sixth month level is quite extensive and Regenocyte covers every aspect of my health in addition to my stem cell progress. The service provided has been first class and all work is done at Regenocyte's Florida location by their doctors and technical staff. Why Dr. Grekos does not belong to ICMS is open to conjecture I am sure. The Regenocyte procedure does not seem to lack prospective Stem Cell Pioneers, people seeking to hopefully improve their lives through this process. They had six leaving for Santo Domingo during the week of my six month review. They continue to leave on a weekly basis from what I know and I have met a number of them during my follow-up procedures at their Florida office.
Regenocyte probably is and has been doing more of these procedures than any other facility even with their high cost. I am sure Regenocyte keeps detailed records on each patient. It would be nice if they shared those records and I wish they would, but I am sure they have reasons and it is their business decision. It seems that Stem Cells relating to the heart at least have definitely helped people and in many cases kept them alive and even brought many back to productive lives. I believe the FDA is dragging their feet in this area. The day will come, maybe not in my lifetime, when people who have stem procedures will no longer be known as Stem Cell Pioneers, but as people who have had the Stem Cell procedure!

Buddy - Dr. Grekos needs to become a part of ICMS in order to maintain credibility in my opinion. I do hope that he will consider it. Patients should politely ask him to participate if we are to ever achieve safe stem cell therapy options here in the U.S. I believe Dr. Grekos is already responding to some of the past concerns. I am told that the cost of the procedure will probably go down. I also have received interest in Regenocyte doing a forum sponsorship on this forum since the posts criticizing the situation with Dr. Grekos and ICMS. ICMS is a non profit group that is here to help patients. It needs good doctors to become an integral part of it in order to achieve its patient oriented goals. ICMS is about saving as many lives as possible. If Dr. Grekos shares a similar viewpoint, I believe he should become an active, participating member of ICMS, no two ways about it.
