A team of doctors from the Children’s Hospital in Philadelphia was able to save the life of a seven-year-old leukemia patient using a genetically modified human immunodeficiency virus or HIV.
For two years, Emily Whitehead, the young patient, had been under chemotherapy. Despite the treatment, she still suffered from two relapses. The doctors later declared that her cancer was in the terminal stage.
In February last year, the doctors decided to subject Emily to an experimental treatment using a genetically modified HIV.
HIV is the cause of AIDS, a disease which weakens the immune system of the body, making the body prone to getting diseases.
In the case of Emily, doctors removed genes from the HIV responsible for developing AIDS. The doctors then added a new gene to the HIV that helps antibodies target cancer cells.
The therapy started with doctors removing millions of Emily’s natural antibodies. Afterwards, the safe HIV with the cancer-fighting gene was introduced to the antibodies, transforming the antibodies. Lastly, these boosted antibodies were injected back into Emily’s body so they could combat the cancer cells.
According to the doctors, the experiment had great results. There were no signs that the patient developed AIDS. More importantly, the boosted cells remain in the patient’s body after the treatment, thereby preventing a relapse. However, the experiment will only be considered successful if these positive results remain for several years.
Because of the promising results, doctors believe the therapy might someday replace the painful bone marrow transplant, the last option for terminal cancer patients.
