Little Sister Saves Her Brother By Donating Bone Marrow

A three-year-old girl from Iraq saved her brother by donating bone marrow.

The girl's 18-year old brother was suffering from a sickle-cell disease with symptomatic anemia and jaundice. Symptomatic anemia occurs when the hemoglobin level is //so less that it does not meet the body's oxygen-carrying demands. Blood loss can be profound, requiring blood transfusions.

New Method Improves Stem Cells to Improve Bone Marrow Transplantation
Mount Sinai researchers have discovered new approach for use of stem cells to improve bone marrow transplantation.

‘The allogenic bone marrow transplantation was successfully conducted on the 18-year old boy from Iraq at the Manipal Hospital in Bengaluru. The bone marrow was donated by his healthy 3-year old sister, whose human leukocyte antigen (HLA)-matched her older brother.’

Ahmed, the 18-year-old boy from Iraq, underwent successful bone marrow transplantation in Manipal Hospital in Bengaluru.

Back in his native, Ahmed had undergone a splenectomy, from where he was referred to Bengaluru for further treatment.

According to Dr. Mallikarjun Kalashetty, consultant Hematology, Hemato -Oncology & Bone Marrow Transplantation at Manipal Hospital, said that Ahmed required an allogeneic bone marrow transplantation.

Bone Marrow Failure Due To Various Causes Now Predicted
Human Bone Marrow Chip that effectively replicates drug- and radiation-induced toxicity responses observed in human patients at clinically relevant doses can be used to predict bone marrow failure.

"The best donors for such patients are the human leukocyte antigen (HLA)-matched siblings who are normal or with a minor form of hemoglobinopathy (a hereditary condition involving an abnormality in the structure of haemoglobin) or thalassemia (a blood disorder involving lower-than-normal amounts of an oxygen-carrying protein)," Dr. Kalashetty explained.

However, things were not as easy for the medical team at the hospital, considering the donor's age, weight, and blood volume. The process required 8-10 liters of blood from the donor who was three years old and weighed 18kgs. The donor only had a blood volume of 1.3 liters.

Vasopressin Cuts Blood Transfusions by Half in Trauma Patients
Penn study shows that trauma patients with severe blood loss, most often gunshot victims, need only half the usual volume of blood when receiving arginine vasopressin treatment.

The donor had to be sedated to elicit co-operation during apheresis, which involves extracting blood and separating components, and preserving the stem cells through cryopreservation.

The dead spaces in the apheresis machine were filled with compatible RBC to counter the low volume of blood going into the machine. Similarly, to reduce the fluid overload, the volume of the fluid going into the body of the child was monitored.

Tamil Nadu woman claims she was infected with HIV through a blood transfusion at Chennai hospital.

The allogeneic bone-marrow transplantation was successful, and Ahmed has now recovered from the sickle-cell disease. The quality of his life has improved significantly. Minor complications after transplantation like mucositis, febrile neutropenia, and viral reactivation, which were effectively managed.
