Umbilical cord stem cells treat heart failure?

Cord blood stem cells show promise treating heart failure....


A heart failure treatment using umbilical cord-derived stem cells may lead to notable improvements in heart muscle function and quality of life.
"We are encouraged by our findings because they could pave the way to a non-invasive, promising new therapy for a group of patients who face grim odds."

Fernando Figueroa MD, Professor of Medicine, Universidad de los Andes, Chile.

The work appears in Circulation Research Journal Report.

In this trial, 30 patients, ages 18 to 75, with stable heart failure receiving optimal drug therapy underwent intravenous infusions with either umbilical cord-derived stem cells or placebo. The umbilical cords were obtained from full-term human placentas of healthy donors by caesarean section after informed consent.

Compared to placebo - stem cell therapy one year following treatment:

• shows sustained, "significant" improvement in heart ability to pump blood
• showed greater improvement in functional status and quality of life
• had no adverse effects — or development of alloantibodies (a common immune complication in patients receiving organ transplants or blood transfusions)

Researchers had previously assessed bone marrow-derived stem cells as potential for treatment, but never evaluated intravenous umbilical cord-derived stem cells. Cord blood stem cells are particularly appealing as they are easily accessible, widely available, unlikely to cause immune complications, and free of the ethical concerns of embryonic stem cells.
"Standard drug-based regimens can be suboptimal in controlling heart failure, and patients often have to progress to more invasive therapies such as mechanical ventricular assist devices and heart transplantation."

Jorge Bartolucci MD, Cells for Cells, Professor, Universidad de los Andes, and lead study author.

Heart failure, marked as the heart's inability to pump blood efficiently, affects some 37 million people worldwide. Despite medical advances, half of patients diagnosed with heart failure die within five years, according to Dr. Figueroa. If affirmed by larger studies, these findings could provide a promising new treatment option for a condition that currently has few.

Abstract
Rationale: Umbilical cord-derived mesenchymal stem cells (UC-MSC) are easily accessible and expanded in vitro, possess distinct properties, and improve myocardial remodeling and function in experimental models of cardiovascular disease. While bone marrow-derived mesenchymal stem cells (BM-MSCs) have been previously assessed for their therapeutic potential in individuals with heart failure and reduced ejection fraction (HFrEF), no clinical trial has evaluated UC-MSCs in these patients.

Objective: Evaluate the safety and efficacy of the infusion of UC-MSC in patients with chronic stable HFrEF.
