Abstract

The role of high dose intravenous IgG (HDIgG) and of hyperimmune CMV IgG (CMV-IgG) in patients undergoing allogeneic hemopoietic stem cell transplantation (HSCT) is still unclear. The aim of this study was to compare prophylactic CMV-IgG with HDIgGin a randomized prospective trial in allogeneic HSCT recipients: primary end point of the study was the occurrence of post-transplant CMV antigenemia (CMVAg-emia). Secondary end-points were severity of acute and chronic graft-versus-host disease (GvHD), infections and transplant related mortality (TRM). Patients were randomized to receive 100 mg/kg/week of CMV-IgG (group A; n = 64) or 400 mg/kg/week of HDIgG (group B; n = 64) from day -7 to day +100. The two groups were comparable for age, diagnosis, disease status, and acute graft-versus host (aGvHD) prophylaxis. The actuarial risk at 1 year of CMV antigenemia was lower for CMV-IgG (61% vs. 71%) but not significantly (p = 0.37); CMVAg-emia occurred at the same interval from HSCT (47 vs. 48 days, p = 0.9), with a comparable number of CMVAg positive cells (3 vs. 3 p = 0.9). Eight patients died of interstitial pneumonia (IP) (4 in each group), two in group A of CMV-IP. Acute GvHD was scored as O-I, II and III-IV in 39 vs. 35, 23 vs. 22 ...Continue Reading

Antifungals

An antifungal, also known as an antimycotic medication, is a pharmaceutical fungicide or fungistatic used to treat and prevent mycosis such as athlete's foot, ringworm, candidiasis, cryptococcal meningitis, and others. Discover the latest research on antifungals here.

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.

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.
