Abstract

Despite the use of conventional chemoprophylaxis regimens, patients receiving unrelated-donor BMT are at high risk of developing severe acute GVHD. We evaluated a prophylactic regimen combining CsA, MTX and anti-CD5-ricin A chain immunotoxin (H65-RTA) in 31 patients; pentoxifylline was also given to reduce the anticipated nephrotoxicity of CsA. In most cases, planned doses of CsA, MTX and H65-RTA were given (i.e. to 77%, 77% and 93% of patients, respectively). Although fluid retention requiring diuretic therapy was frequent, only 1 patient had a > 10% unexplained increase in body weight during the first 21 days post-BMT. Also, while significant increase of the baseline serum creatinine was noted in 7 patients, none required dialysis. One patient suffered a reversible allergic reaction to the immunotoxin; no other side effects attributable to this regimen were observed. All but 2 patients engrafted (1 died of fungemia on d + 19 and the other had persistent leukemia) and no late graft failures were observed. Seventeen patients developed acute GVHD grade > or = II (probability, 58% [95% CI 41-76%]); 7 had grade > or = III (probability, 24% [95% CI 12-43%]). In the 27 patients who achieved stable engraftment and have survived beyon...Continue Reading

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.

Astrocytes

Astrocytes are glial cells that support the blood-brain barrier, facilitate neurotransmission, provide nutrients to neurons, and help repair damaged nervous tissues. Here is the latest research.
