Stem cell transplantation in a 42-year-old HIV patient with leukemia has wiped out the virus from his body, the doctor of Berlin Charité Hospital confirms.
“The patient is fine,” said Dr. Gero Hutter, a haematologist at the Berlin Charité Hospital. “Today, two years after his transplantation, he is still without any signs of HIV disease and without antiretroviral medication.”

The doctor observed that using the stem cells from a donor who carries a unique gene mutation i.e. delta 32 ccr5 along with a tissue match, could now cure the patient from the HIV virus. Delta 32 ccr5 makes the cells resistant to HIV virus and this mutation is found in a little more than 1 percent of Caucasians.
Dr. Hutter told, “When the recipient got the new bone marrow, his cells could now block out the HIV, and, in effect, he was cured. Bone marrow transplants are high risk, so only lymphoma and leukemia patients take the risk to possibly cure their cancer.”

The study is published Wednesday in the New England Journal of Medicine.

Mandi Schwartz ’11 completed a crucial step in her battle with leukemia Wednesday afternoon.

The women’s hockey player received a long-awaited stem cell transplant at about 3:30 p.m. local time at the inpatient transplant unit of the Seattle Cancer Care Alliance at the University of Washington Medical Center. The procedure took 32 minutes and there were no complications, said Dean Forbes, a spokesman for the cancer center.

Schwartz, a native of Saskatchewan, Canada has been in and out of chemotherapy for more than 20 months since first being diagnosed with acute myeloid leukemia in December 2008. After months of searching for an adequate bone marrow or stem cell donor, two “five-out-of-six” stem cell matches were located and Schwartz’s transplant was slated for Aug. 27, as she was declared in remission on June 9. But the timeline changed when Schwartz learned on Aug. 11 that her cancer had returned for a third time.

On Aug. 31, Schwartz entered remission once again after completing additional chemotherapy. She underwent a daily pair of hour-long radiation sessions between Sept. 15 and 17, and had another two days of chemotherapy on Sunday and Monday to prepare for the transplant.

Now, with the procedure completed at last, Schwartz will wait to see if the stem cells engraft. Forbes said it will take about three weeks to determine whether the transplant was successful. Schwartz will remain in the hospital during that stretch of time because her immune system is still weak.

The King Abdulaziz Medical City in Riyadh is getting ready to open a stem cell bank harvested from the umbilical cord. The procedure will be done in laboratories and specially equipped rooms to draw the cells from umbilical cord blood and separate them using a special device.

Then they will be stored in labs for a period from 15 to 20 years after examining them and making sure they are free of contagious and genetic diseases. In addition, a team will be prepared for coordinating, marketing and research within this field.

In a ray of hope for millions of leukaemia patients, American scientists have claimed to have developed a technique which multiplies the small number of stem cells in the donor blood, making it much more potent for the treatment of the fatal disease.

It also eliminates the need for a matching donor, whose bone marrow is usually transplanted to the patient, according to a study which appeared in the journal Nature Medicine. Traditionally, there was always a risk that the patient’s body may reject the new cells from a donor.

(…) Participation in this drive and thus registration with the National Marrow Donor Program consists of simple swabs of the cheeks using Q-tips for a DNA test. DNA information is entered into this lifesaving donor program database. If a potential donor is identified as a potential match for David or someone else in need, he/she will be contacted by the donor program to have a small amount of blood drawn for lab testing.

If that person is then confirmed as a match, he/she will be asked to provide stem cells through a simple donation procedure where blood is taken from one arm through a needle and run through a machine, which separates the stem cells from the blood, and returned into the other arm.

Myelodysplastic Syndromes (MDS) are a group of diseases that affect the bone marrow and blood. Some types of MDS are mild and easily managed, which other types are severe and life-threatening. Mild MDS can grow more severe over time. It can develop into a fast-growing, severe leukemia called acute myelogenous leukemia. Stem cell transplant is the only treatment that can cure MDS.

In this treatment, the patient receives high-dose chemotherapy and/or total body irradiation to kill the cells in the bone marrow (including the abnormal bone marrow cells). The patient would then receive new functioning blood-forming stem cells harvested from the donor (…)

A breakthrough was achieved recently in the case of an 18 year old boy, a case of advanced stage of Aplastic anemia where stem cells of not one but three donors were used to treat him. This spectacular feat was achieved by the doctors at The Netaji Subhash Chandra Bose Cancer Research Institute (NSCBCRI) Kolkata.

18 year old Aman, student of class 12, fainted in school. He was diagnosed for Aplastic Anemia, a disorder where the bone marrow stops producing red blood cells and platelets. He was treated in many hospitals, but no amount of blood transfusions or ‘immuno-suppressant’ medication could help.

Dejected and depressed, Aman’s parents had almost lost their son when they happened to read a news report by chance. The doctors at NSCBCRI had successfully conducted an SCT to treat Aplastic anemia. . “I wanted to live on, and my parents saw a ray of hope, ”said Aman.
With recent advances in medicine the use of stem cells have been very effective in treating Diabetes milletus, Parkinson’s diseases, cancer, leukemia and Aplastic anemia .

They have been very effective in Bone marrow transplantation
Aman was rushed to Kolkata, but by then his condition had deteriorated. The doctors realized that only a multiple- unit SCT could save him. Overruling the risks they conducted the transplant which took three days.

With 50% chances of risk involved in a single unit SCT, the doctors had a bigger risk at hand, but a similar case conducted successfully in Seattle gave them the courage.
Today Aman Khandelwal is recouping. Thanks to the courage, confidence and competence of the doctors who treated upon him.
