Bone marrow transplants

Bone marrow transplants

The infusion of bone marrow into a patient who has been treated with high dose chemotherapy or radiation therapy. Patients may use their own marrow, which in some cases has been frozen.

LONDON (Reuters) - Scientists have managed to halt a rare and fatal brain disease with an experimental gene therapy technique using a deactivated version of the AIDS virus, a study published on Thursday showed. The international team used a disabled form of human immunodeficiency virus (HIV) to deliver working genes to two boys with the brain disease X-linked adrenoleukodystrophy (ALD). Their success may help shape future treatment. Patrick Aubourg of Inserm-University Paris Descartes, who led the study, said it was the first time scientists had successfully used an HIV-derived delivery technique for gene therapy in humans, and the first time gene therapy had been ...

French scientists mixed gene therapy and bone marrow transplants in two boys to seemingly halt a brain disease that can kill by adolescence. The surprise ingredient: They disabled the HIV virus so it couldn't cause AIDS, and then used it to carry in the healthy new gene. The experiment marks the first time researchers have tried that long-contemplated step in people — and the first effective gene therapy against a severe brain disease, said lead researcher Dr. Patrick Aubourg of the University Paris-Descartes. Although it's a small, first-step study, it has "exciting implications" for other blood and immune disorders that had been feared beyond ... Read Full Story

A strategy that combines gene therapy with blood stem cell therapy may be a useful tool for treating a fatal brain disease, French researchers have found. These findings appear in the 6 November 2009 issue of the journal Science, which is published by AAAS, the nonprofit science society. In a pilot study of two patients monitored for two years, an international team of researchers slowed the onset of the debilitating brain disease X-linked adrenoleukodystrophy (ALD) using a lentiviral vector to introduce a therapeutic gene into patient's blood cells. Although studies with larger cohorts of patients are needed, these results suggest that gene therapy with ... Read Full Story

Sixteen month old Marcus Espino was diagnosed on July 1994 with a grave genetic storage ailment known as Muccopolysaccaridosis 1H, also called as MPS1 or Hurler’s syndrome. The doctors informed his parents that his sole likelihood of survival was if underwent a bone marrow transplant or BMT. The onset of Hurler’s syndrome is the result of the body’s incapability for producing a particular enzyme known as alpha-iduronidase. Generally, the body utilises enzymes for processing proteins, sugars and other matter alongside breaking down and reprocessing cells following their death. However, in kids having Hurler’s syndrome and other storage disorders, the absent or deficient enzyme thwarts ... Read Full Story

Diagnosis & Tests The doctor would initially conduct a thorough physical exam and check whether the liver, spleen, groin, neck and lymph nodes in the under arms are showing any kind of swelling. A CBC blood test would be ordered for finding out the complete blood count that evaluates the number of white and red blood cells and platelet count in the blood. Additionally, the blood sample is microscopically analysed to check for appearance of the cells and in determining the amount of mature cells and leukemia cells known as blasts. Though blood tests might show the presence but they mostly do not reveal ... Read Full Story

Chronic myelogenous leukemia (CML) is a chronic form of leukemia linked to a particular genetic anomaly in the leukemia cell known as the Philadelphia chromosome (T9 or T22). Chronic Myelogenous Leukemia Causes: The production of the anomalous gene occurs due to the displacement of the genetic material ABL from chromosome 9 that occupies the position of the normal part of chromosome 22 located close to a region known as BCR. The resultant fusion gene BCRABL causes the ABL gene to function in anomalous manner leading to the development of leukemia. Chronic Myelogenous Leukemia Symptoms: Majority of the patients that have developed CML initially seek ... Read Full Story

It's long been said that it takes a lot of heart to tackle the Ironman World Championship. Kyle Garlett is the first triathlete to try it with someone else's heart. On Saturday, three years to the day that he received his heart transplant, Garlett will be among nearly 1,800 triathletes lined up along Kailua Bay, eager to get started on the 140.6-mile endurance race that includes a 2.4-mile ocean swim, 112-mile bike ride and a 26.2-mile run. "I really want to finish the race, but it won't define anything about me," said Garlett, 38. "It would put an exclamation on my recovery. Three years ... Read Full Story

Bone marrow  
The soft, sponge-like tissue in the center of most bones. It produces white blood cells, red blood cells, and platelets.

Bone marrow ablation  
The destruction of bone marrow using radiation or drugs.

Bone marrow aspiration
The removal of a small sample of bone marrow, usually from the hip, through a needle for examination under a microscope.

Bone marrow biopsy
The removal of a sample of tissue from the bone marrow with a needle for examination under a microscope.

Bone marrow cancer  
Cancer that forms in the blood-forming cells of the bone marrow. Bone marrow cancer includes leukemias, multiple myeloma, and others.

Bone marrow metastases  
Cancer that has spread from the original tumor to the bone marrow.

Bone marrow transplantation
A procedure to replace bone marrow that has been destroyed by treatment with high doses of anticancer drugs or radiation. Transplantation may be an individual's own marrow saved before treatment, marrow donated by someone else, or marrow donated by an identical twin.

Edema
Swelling caused by excess fluid in body tissues.

Enchondroma
A benign growth of cartilage in bones or in other areas where cartilage is not normally found.

For some individuals with leukemia, the best treatment option is to receive a bone marrow transplant from a person who is not an identical genetic match. The donor bone marrow gives rise to immune cells that attack the leukemia (a response known as a

Treatment on this research study is an experimental and unproven way to treat cancer. This treatment uses healthy donors’ white blood cells to fight your disease. If you agree to participate, you will receive several infusions of white cells through a line inserted into a vein in your arms, or through the central venous line if available. The number of infusions you will receive will depend on the number of white cells obtained from the donors...

Background: The regulation of growth and apoptosis in K562 cells by human bone marrow mesenchymal stem cells (MSCs) from leukemia patients was investigated. Methods: K562 cells were cocultured with leukemic MSCs under serum deprivation. Cell Counting Kit-8 (CCK-8), PI staining, Annexin V/PI binding and FACS assays were used to investigate cell proliferation, cell cycle status, and apoptosis of K562 cells cultures in the presence or absence of...
