Background: A retrospective investigation was conducted to determine whether autologous blood collection could reduce allogenic transfusion after resection of esophageal cancer and whether allogenic transfusion influenced postoperative infection.
Methods: Patients (n = 100) who met the criteria for hemoglobin, age, body weight, and serum protein donated 800 mL of autologous blood from May 1994 to December 1997. The control group (n = 248) was selected from patients who met the same criteria and did not donate autologous blood over the 10 years before the start of autologous blood collection.
Results: Only three patients (3%) from the autologous group required allogenic transfusion versus 84 patients (33.7%) from the control group. Sixteen of the 26 patients who received more than 4 units of allogenic blood contracted postoperative infections compared with 25 of 165 patients who did not (P < .0001). Autologous blood transfusion significantly increased the probability of avoiding allogenic transfusion (odds ratio, 27.58), and allogenic transfusion was significantly related to postoperative infection (odds ratio, 1.19), according to logistic regression analysis.
Conclusions: Autologous blood collection reduces the need for allogenic transfusion in patients undergoing resection of esophageal cancer, and avoidance of allogenic transfusion may reduce the risk of postoperative infection.

Hereditary non-spherocytic hemolytic anemia with GPI mutations successfully treated with allogeneic hematopoietic stem cell transplantation: a first report of two cases.

Glucose phosphate isomerase (GPI) deficiency caused by GPI gene mutations is a rare heterogenous condition that causes hereditary non-spherocytic hemolytic anemia (HNSHA). Patients who suffer from severe anemia may need more effective treatment. Here, clinical data and genetic testing results of two cases of HNSHA with GPI mutations treated with allogeneic hematopoietic stem cell transplantation (allo-HSCT) were retrospectively analyzed.

Transfusion of blood products is a common lifesaving medical procedure in clinical practice. However, it poses the risk of potential adverse reactions for the recipient. Transfusion-associated graft-versus-host-disease (TA-GVHD) is a rare adverse event, fatal in >90% of cases.

We previously reported that the area under the curve of log-transformed cytomegalovirus antigenemia (CMV-AUC) until 100 days after allogeneic hematopoietic cell transplantation (allo-HCT) was associated with an increased risk of non-relapse mortality. We applied a risk-adapted letermovir (LTV) prophylaxis strategy guided by a risk score that predicts a higher CMV-AUC. First, we retrospectively analyzed 278 allo-HCT recipients between 2007 and 2017 (Period 1).

Background: Metastatic spine tumor surgery (MSTS) is often complex and extensive leading to significant blood loss. Allogeneic blood transfusion (ABT) is the mainstay of blood replenishment but with immune-mediated postoperative complications. Alternative blood management techniques (salvaged blood transfusion [SBT]) allow us to overcome such complications.

Allogeneic chimeric antigen receptor (CAR) T cells targeting disialoganglioside-GD2 (ALLO_GD2-CART01) could be a therapeutic option for patients with relapsed or refractory, high-risk neuroblastoma (r/r HR-NB) whose tumors did not respond to autologous GD2-CART01 or who have profound lymphopenia. We present a case series of five children with HR-NB refractory to more than three different lines of therapy who received ALLO_GD2-CART01 in a hospital exemption setting. Four of them had previously received allogeneic hematopoietic stem cell transplantation.
