Three years after a stem cell transplant from a donor with rare genetic characteristics, an American patient has overcome the disease.

This information revealed in the professional journal Blood by German scientists have real hope for 33 million people infected with HIV.

Stem cell transplant

The patient is cured, aged about forty years and having the disease for ten years was treated for leukemia in 2007 by stem cell taken from bone marrow from a donor with rare genetic characteristics of preventing contracting AIDS. These same characteristics are present in 1% of the population.Scientifically confirmed by the American Society of Hematology, treatment of this leukemia thereby obtained as an unexpected side effect cure of AIDS in this patient. No recurrence of the virus could be detected from this patient who underwent extensive examinations from 2008, despite a complete cessation of its antiretroviral treatment.

Confirmatory tests

Moreover, before disclosing the incredible news, the scientists involved have made this year to new tests, all negative, thus proving the complete disappearance of the virus in this patient.

Generalization difficult

Effective treatment will still be difficult to reproduce in a short time in that 30% of patients on average do not survive a bone marrow transplant. “More research needs to be put in place to replicate this result without putting lives at risk, “said Karen Tashima, director of HIV clinical trials program at Miriam Hospital in Rhode Island. She adds that antiretroviral treatment is effective in controlling the virus and it would not be ethically correct to refer all patients to such extreme treatments.

This is still a great step forward in research to cure disease, and it gives new hope to the scientists, from this crucial event, will focus part of this research to the transposition of this discovery in new forms like processes safer. According to David Baltimore, Nobel Prize for Medicine in 1975 and founder of a biotechnology company developing its own anti-AIDS treatments by stem cells, you have to be excited about this new value and give a strong argument to guide research in this direction.

Maintaining vigilance

Finally, and to remove any euphoria can be linked to the new, it is important to emphasize that the opinions are unanimous regarding the obligation to continue to protect themselves from infection by the means of protection available to us.
